1845 2008-08-01 Gary Dismukes <dismukes@adacore.com>
1847 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1848 Orig_Prev to Prev in the case where the actual is N_Function_Call or
1849 N_Identifier. This was interfering with other cases that are rewritten
1850 as N_Identifier, such as allocators, resulting in passing of the wrong
1851 accessibility level, and based on testing this code is apparently no
1852 longer needed at all.

4013 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4014 non-controlling formals (and the return type, even though this is not
4015 explicit in the standard) must support external streaming.

4017 as above for of RAS types and RCI subprograms. (The return type is not

4022 * sem_util.ads, sem_util.adb
4023 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4024 Is_Remote_Call_Interface to identify RACW types in a stable and
4025 consistent way. We used to rely in this predicate on the privateness of
4026 the designated type and its ancestors, but depending on the currently
4027 visible private parts, this caused false negatives. We now uniformly
4028 rely on checks made at the point where the RACW type is declared.

4040 constants declared in scopes other than packages since they can be
4041 completed with pragma Import.
4042 Add missing escaping of all-caps word 'CPP' in error messages.
4043 (Build_Discriminated_Subtype): Do not inherit representation clauses
4044 from parent type if subtype already carries them, because they are
4045 inherited earlier during derivation and already include those that may
4046 come from a partial view.
4048 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

4084 operation of an RACW stub type (these primitives are only executed
4085 through dispatching, never through static calls).
4086 (Collect_Interps): When only one interpretation has been found, set N's
4087 Entity and Etype to that interpretation, otherwise Entity and Etype may
4088 still refer to an interpretation that was ignored by Add_One_Interp,
4089 in which case would end up with being marked as not overloaded but with
4090 an Entity attribute not pointing to its (unique) correct interpretation.

4106 (packed) array itype, because it is an unrelated type whose source
4107 location is independent of the point of creation of the itype itself.

8390 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid
8391 generation of spurious error if parent is an interface type; caused
8392 because predefined primitive bodies will be generated later by
8394 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
8396 (Derive_Subprograms): Handle derivations of predefined primitives
8397 after all the user-defined primitives to ensure that they are
8398 found in proper order in instantiations.

8400 of Related_Interface to Related_Type.
8401 (Record_Type_Declaration): Minor reordering of calls to decorate the

8403 before setting its Is_Tag attribute.
8404 (Analyze_Subtype_Declaration): In the case of subtypes with
8405 Private_Kind, inherit Known_To_Have_Preelab_Init from the parent.

8410 * sem_ch4.adb (Analyze_Selected_Component): Include the requeue
8411 statement to the list of contexts where a selected component with a
8412 concurrent tagged type prefix should yield a primitive operation.
8413 (Find_Primitive_Operation): Handle case of class-wide types.
8414 (Analyze_Overloaded_Selected_Component): If type of prefix is
8415 class-wide, use visible components of base type.
8416 (Resolve_Selected_Component): Ditto.
8417 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
8418 formal of a generic subprogram. find candidate interpretations by
8419 scanning the list of generic formal declarations.:
8420 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8421 type from a limited_with_clause, and the full view is available, use it
8422 for subsequent semantic checks.
8423 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
8424 (Find_Primitive_Operation): New function.
8425 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8426 only once if several interpretations of the prefix yield an access type.
8427 (Try_Object_Operation): Code and comment cleanup.
8428 (Analyze_Selected_Component): Reorder local variables. Minot comment and
8429 code reformatting. When the type of the prefix is tagged concurrent, a
8430 correct interpretation might be available in the primitive and

8455 perform subtype conformance between the formals of the current entry
8456 and those of the target interface primitive.
8457 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8458 Timed_Entry_Call): Analyze the triggering statement as the first step of
8459 the processing. If this is a dispatching select, postpone the analysis
8460 of all select statements until the Expander transforms the select. This

8462 replicated some of the select statements. In case the Expander is
8463 disabled, perform regular analysis.
8464 (Check_Triggering_Statement): New routine.
8465 (Analyze_Requeue): Exclude any interpretations that are not entries when
8466 checking overloaded names in a requeue. Also test type conformance for
8467 matching interpretations rather than requiring subtype conformance at
8468 that point to conform with the RM's resolution rule for requeues.

8472 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8473 inherited operation is a defaulted tag-indeterminate call, and there is
8474 a statically tagged actual, use the static tag as a controlling actual
8475 for the defaulted actual.
8477 2007-12-13 Geert Bosch <bosch@adacore.com>

8504 latest Ada 2005 rules about renaming and 'Access of
8505 discriminant-dependent components.

9059 a predefined entity (as happens for array index types), the line is set
9061 Add support for parsing multiple array index types info, or
9062 multiple inherited interfaces info. This information cannot be stored
9063 in Xref_Entity_Record, which only supports a single instance of Tref_*,
9064 and is therefore stored in the list of references instead. It has a
9065 special treatement later on in tools that use this information.

9079 Dismukes). After this patch there is no need to perform any
9080 additional management on these nodes in Expand_Interface_Actuals.
9082 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9083 that handles use of 'Access and 'Unchecked_Access applied to
9084 actuals covering interface types. Such code is now
9085 centralized in Expand_N_Attribute_Reference.
9087 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9089 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
9090 of tagged types whose ultimate ancestor is a CPP type.

9121 * vx_stack_info.c: New file.
9123 * i-forbla-unimplemented.ads: New file.
9125 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
9126 for unsupported configurations; use it on VMS targets instead of the

9129 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9130 used by VxWorks targets to have access to task-specific data and be
9131 able to extract the stack boundaries for stack checking.
9132 Use system-vms-ia64.ads on ivms.
9134 * Make-lang.in: Update dependencies.

9175 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9176 association for an access component, add an association with null as
9177 the expression. Remove testing for array subtypes and the setting in
9178 that case of Ctyp to the array component type, which prevented proper
9179 inclusion of an association for null-initialized arrays. Collapse
9180 condition that tests for array subtypes into just a test of
9181 Is_Partially_Initialized_Type (which already covers arrays anyway).

9198 * sem_ch4.adb: Minor code and comment reformatting.
9199 (Analyze_Allocator): When the designated type of an unconstrained
9200 allocator is a record with unknown discriminants or an array with
9201 unknown range bounds, emit a detailed error message depending on the
9202 compilation mode and whether the designated type is limited.

9416 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9418 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9421 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9423 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9426 * sem_dist.ads: Minor comment fix
9428 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9430 2007-09-26 Javier Miranda <miranda@adacore.com>
9431 Eric Botcazou <ebotcazou@adacore.com>
9434 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9435 indirection added to the HT_Link component of the TSD. This is required
9436 to statically allocate the TSD.
9439 Minor reordering of the declarations in the private part. Required to
9440 add a level of indirection to the contents of the TSD component HT_Link.
9441 This is required to statically allocate the TSD.
9443 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9444 Is_Statically_Allocated set from constant objects.
9445 Do not make exported constants created by the compiler volatile.
9446 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9449 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9450 before returning them.
9452 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9453 public part of the package.
9454 (Make_DT): Move HT_Link component out of the TSD record. For this
9455 purpose Make_DT now declares a separate object that stores the
9456 HT_Link value, and initializes the TSD component with the address
9457 of this new object. The addition of this level of indirection is
9458 required to statically allocate the TSD because the TSD cannot
9459 have variable components.
9460 (Expand_Interface_Conversion): Improve the expanded code.
9461 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9463 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9464 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9465 if we are building static dispatch tables then we must not generate
9466 extra code to register the primitive because the dispatch table will
9467 be built at the end of the library package; otherwise we notify that
9468 we cannot build the static dispatch table.
9470 2007-09-26 Robert Dewar <dewar@adacore.com>
9472 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
9475 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
9476 (Analyze_Record_Representation_Clause): Suppress junk warning for
9477 missing component clause.
9478 (Analyze_Attribute_Definition_Clause, case Address): Apply the special
9479 tests for controlled type overlay to composites with controlled
9481 (Analyze_Record_Representation_Clause): Add reference for component name
9483 2007-09-26 Javier Miranda <miranda@adacore.com>
9484 Gary Dismukes <dismukes@adacore.com>

9487 for thunks associated with interface types.
9489 * einfo.ads: Improve documentatation of Is_Internal
9490 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9491 associated with interface types.
9492 Extensive comment fixes regarding flags that appear in all entities. The
9493 documentation is now consistent for all such flags (there were a number
9494 of errors in the documentation in this regard).
9496 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9498 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9499 of these procedures are passed a function call that already has
9500 build-in-place actuals (testing new flag
9501 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9502 the case where processing continues.
9503 (Expand_Call): If the call is generated from a thunk body then we
9504 propagate the extra actuals associated with the accessibility
9505 level of the access type actuals.
9507 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9508 of each extra formal of a protected operation to reference the
9509 corresponding extra formal of the subprogram denoted by the
9510 operation's Protected_Body_Subprogram.
9512 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9513 N_Function_Call nodes.
9515 2007-09-26 Robert Dewar <dewar@adacore.com>
9517 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9519 * debug.adb: Add d.s flag.
9521 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9523 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9524 debug variable so that it won't be initialized when pragma
9525 Initialize_Scalars is in effect.
9527 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9529 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9530 initialization of a full view. This is moved to
9531 Analyze_Package_Specification.
9533 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9534 preelaborable initialization of a full view in entity loop.
9535 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9536 its child units are use-visible only if they are visible child units.
9538 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9539 whether an expression can be used within a type declaration that
9540 requires preelaborable init.
9541 (Check_Components): Replace inline code that does partial checking for
9542 preelaborable default expressions with call to
9543 Is_Preelaborable_Expression.
9544 (Has_Preelaborable_Initialization): In the case of a generic actual
9545 subtype, (that is, Is_Generic_Actual is True), return the result of
9546 applying Has_Preelaborable_Initialization to the generic actual's base
9549 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9551 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9552 call to Jan_1_Day _Of_Week to optimize its performance.
9553 (Is_Leap): Move the routine to the scope of Week_In_Year.
9554 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9555 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9556 avoids calling Time_Of and Split, thus making it more efficent.
9557 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9559 * g-calend.ads (Week_In_Year): Change comment to reflect new
9562 2007-09-26 Emmanuel Briot <briot@adacore.com>
9564 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9565 Command_Line): New types
9566 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9567 support for defining how switches can be grouped on a command line (as
9568 is the case for -gnatw... for GNAT), and how simple switches can be
9569 used as aliases for more complex switches (-gnatwa is same as
9571 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9572 (Start, Current_*): New subprograms
9573 Added support for parsing an array of strings in addition to the real
9575 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9576 be moved from the body to the private part of the spec.
9577 (*): All subprograms now have an extra parameter with default value to
9578 specify which parser should be used. For backward compatibility, it
9579 defaults to parsing the command line of the application. They were also
9580 modified to properly handle cases where each of the argument does not
9581 start at index 1 (which is always true for Ada.Command_Line, but not
9582 when processing any Argument_List).
9583 (Free): New subprogram
9584 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9585 Argument): New subprograms
9586 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9587 special characters like ':', '=',... are now handled in a single place,
9588 which makes the code more extensible eventually.
9589 (Getopt, Full_Switch): When the switch was returned as part of the
9590 special character '*', make sure it is prepended by the switch character
9591 ('-' in general), so that the application knows whether "foo" or "-foo"
9592 was specified on the command line.
9594 2007-09-26 Florian Villoing <villoing@adacore.com>
9596 * g-dirope.adb (Remove_Dir): In case we are removing directories
9597 recursively, make sure that if an exception is raised during the
9598 processing, the current working directory is reset to its initial
9599 value before propagating the exception.
9601 2007-09-26 Vincent Celier <celier@adacore.com>
9603 * gnatbind.adb: If there are several ALI files specified and there is
9604 a main program to bind, the first ALI is expected to contain the main
9605 subprogram and the names of the binder generated files will be derived
9606 from the first ALI file name.
9607 (Gnatbind): Fix insertion character in invocation of Error_Msg
9609 2007-09-26 Vincent Celier <celier@adacore.com>
9611 * gnatcmd.adb (Check_Files): Do not include sources that have been
9612 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9614 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9616 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9617 information about each of its index types, following the type
9618 reference for its component type.
9620 2007-09-26 Vincent Celier <celier@adacore.com>
9622 * make.adb: (Kill): New procedure (__gnat_kill imported)

9629 sources, so that the correct paths will be found.
9631 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9633 2007-09-26 Vincent Celier <celier@adacore.com>
9635 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9637 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9638 Replace components Compiler_Min_Options and Binder_Min_Options with
9639 Compiler_Required_Switches and Binder_Required_Switches in record
9641 Remove components Default_Language and Config in Project_Tree_Data,
9644 * prj-attr.adb: New attributes Required_Switches (<language>) in
9645 packages Compiler and Binder.
9647 * prj-nmsc.adb: Major rewrite of the processing of configuration
9648 attributes for gprbuild. No impact on GNAT tools.
9650 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9651 process configuration attributes: this is done in Prj.Nmsc.Check.
9652 (Recursive_Process): Make a full copy of packages inherited from project
9653 being extended, instead of a shallow copy.
9654 (Process_Project_Tree_Phase_1): New procedure

9656 (Process): Implementation now uses the two new procedures
9658 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9659 from the project config, not the tree config that no longer exists.

9685 ancestor of the derived type, the operations are inherited from the
9686 primary dispatch table of the parent.
9687 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9688 when the context is an explicit type conversion.

9987 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
9988 create an abstract subprogram in the case of 'Input. For 'Output we now
9989 create a real spec/body when the type is abstract, since it can
9990 potentially be called.
9991 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
9992 body for 'Output when the type is abstract (only the creation of the
9993 body for 'Input is excluded when the type is abstract).
9994 (Stream_Operation_OK): Add an additional condition in the return
9995 statement, so that False will be returned for TTS_Stream_Input if the
9996 associated tagged type is an abstract extension. Add comments for
9998 (Expand_N_Object_Declaration): For the case of a shared passive
9999 variable, insert init proc call only after the shared variable
10000 procedures have been processed, because the IP call needs to undergo
10001 shared passive variable reference expansion, which requires these
10002 procedures to be available (and elaborated).

10012 given a box association, the type of the component is discriminated,
10013 and the value of the discriminant is the discriminant of the enclosing
10014 type, retrieve its value from the aggregate itself, where it must have
10017 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10018 to remove other spurious ambiguities on arithmetic operations involving
10019 literals and addresses, on systems where Address is a visible integer
10020 type, when the operator is called in functional notation.
10021 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10022 is legal when the types match, even if the operation is currently
10025 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10027 * sem_ch12.adb (Build_Local_Package): A formal package with no
10028 associations is legal if all formals have defaults. It is not
10029 equivalent to a formal declared with a box.

10064 the N_Indexed_Component case.
10065 <N_Indexed_Component>: Fall through to above case.

10147 (Write_Entity_Flags): Write the status of flag Is_Raised.
10148 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10149 spurious ambiguities when integer literals appear in the context of an
10150 address type that is a visible integer type.

10175 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10176 occurring in the list of entities to qualify, and do not attempt to

10210 value of the right operand directly.
10212 * stringt.adb (Store_String_Chars): Optimize by growing the
10213 String_Chars table all at once, rather than appending characters one by
10215 (Write_String_Table_Entry): If the string to be printed is very long,
10216 just print the first few characters, followed by the length. Otherwise,
10217 doing "pn(n)" in the debugger can take an extremely long time.
10219 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10220 Store_String_Char with Store_String_Chars.

10237 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10239 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10240 flag, for effiency. It is called when analyzing arithmetic operators
10241 and also for actuals in calls that are universal_integers. The flag is
10242 set for the predefined type address, and for any type or subtype
10245 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10246 Universal_Integer, when the formal is a descendent of address and the
10247 call appears in user code.

10320 (Set_Debug_Renaming_Link): Change to set Node25.
10321 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10322 (Write_Field25_Name): Add case for E_Variable to output
10323 "Debug_Renaming_Link".
10324 (Write_Field23_Name): Correct the output string for "Limited_View".
10326 * exp_dbug.adb: Add with and use of Tbuild.
10327 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10328 and literal with creation of a variable of type
10329 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10330 and the entity of the renaming declaration.
10331 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10332 part of the name of a variable that has a Debug_Renaming_Link.
10334 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10335 special type to be associated with variables that provide debugger
10336 encodings for renaming declarations.

10339 Ed Schonberg <schonberg@adacore.com>
10340 Javier Miranda <miranda@adacore.com>
10342 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10343 ancestor part given by an aggregate to test for an unchecked conversion,
10344 since this can occur in some cases when the ancestor part is a function
10345 call, and we don't want to fall into the recursive call to this
10346 procedure in that case.
10348 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10349 stream attributes on limited types to account for user-specified
10350 attributes as well as whether Input (resp. Output) becomes available
10351 due to Read (resp. Write) being available for the type. Change Boolean
10352 variable to the more accurate name
10353 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10354 double-"not" predicate at beginning of return statement to more
10355 understandable form.
10357 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10358 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10359 in a block statement and use that as the first statement of the
10360 expanded return rather than incorrectly using the handled sequence as
10361 the first statement.
10363 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10364 operation, generate an explicit freeze node for it rather than
10365 generating extra formals, to ensure that gigi has the proper order of
10366 elaboration for anonymous subtypes in the signature of the subprograms.
10367 (Build_In_Place_Formal): Move assertion to beginning of loop.
10368 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10369 applied to a function call (occurs for some cases of 'Input).

10371 applied to a function call (occurs for some cases of 'Input).
10373 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10374 2005, generate an extended return statement enclosing the result object
10377 * freeze.adb (Freeze_Record_Type): Extend the current management of
10378 components that are access type with an allocator as default value: add
10379 missing support to the use of qualified expressions of the
10380 allocator (which also cause freezing of the designated type!)
10381 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10382 dispatching operation, since extra formals may be needed by calls to
10383 build-in-place functions (such as stream 'Input).
10385 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10386 formals for 'Constrained and accessibility level in the case of a
10387 predefined dispatching operation.
10389 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10390 point, no need to find the parent node.
10392 2007-08-16 Javier Miranda <miranda@adacore.com>
10394 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10395 and entry barriers.
10397 2007-08-16 Javier Miranda <miranda@adacore.com>
10399 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10400 is not really required and can introduce regression with the debugger.
10401 The original problem is fixed with the patch written for checks.adb.
10403 2007-08-16 Thomas Quinot <quinot@adacore.com>
10405 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10406 Range_Check on Allocated_Table.
10408 2007-08-16 Vincent Celier <celier@adacore.com>
10410 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10411 Including_Non_Switch set to False.
10412 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10413 Including_Non_Switch set to False.
10415 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10416 parameter Including_Non_Switch, defaulted to True. When
10417 Including_Non_Switch is False, options that are not switches and
10418 appear as relative path are not converted to absolute paths.
10420 2007-08-16 Nicolas Roche <roche@adacore.com>
10422 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
10425 * Make-lang.in: Update dependencies
10427 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10429 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10430 currently inspected is a selected component, retrieve the entity of
10432 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10433 from the immediate ancestor of Main_Unit_Entity.
10434 (Install_Limited_Withed_Unit): Do not install the limited view of
10435 package P if P is reachable through an ancestor chain from package C
10436 and C also has a with clause for P in its body.
10437 (Has_Limited_With_Clause): New routine.
10438 (Has_With_Clause): New routine.
10440 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10442 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10443 generic for an enclosing instance is a global reference, even though
10444 its scope is the enclosing instance.
10446 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10447 Javier Miranda <miranda@adacore.com>
10449 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10450 initialize a limited object.
10451 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
10453 Make sure Has_Complex_Representation is inherited by derived type.
10455 2007-08-16 Robert Dewar <dewar@adacore.com>
10457 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10460 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10462 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10463 implements an operation inherited from a progenitor interface, verify
10464 that they are subtype-conformant.
10466 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10467 Bob Duff <duff@adacore.com>
10468 Nicolas Setton <setton@adacore.com>
10470 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10471 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10472 the statement which is being resolved comes from a predefined library
10473 unit, all non-predefined library interpretations are skipped.
10474 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10475 but the "&" is user defined, give an error, because the folding would
10478 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10479 the parser has folded a long sequence of concatenations of string
10482 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10483 and "JMP_BUF" variables as artificial.
10484 (N_String_Literal): Do not use alloca for very long string literals. Use
10485 xmalloc/free instead. Otherwise the stack might overflow.
10487 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
10490 2007-08-16 Vincent Celier <celier@adacore.com>
10492 * vms_conv.adb (Process_Argument): Ensure that project related options
10493 are not put in the -cargs section when using GNAT COMPILE.
10495 2007-08-16 Robert Dewar <dewar@adacore.com>

10523 s-osinte-solaris.adb, s-osinte-solaris.ads,
10524 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
10526 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
10527 switch -gnatyS. Enable -gnatyS in GNAT style check mode
10529 2007-08-14 Robert Dewar <dewar@adacore.com>
10530 Ed Schonberg <schonberg@adacore.com>
10532 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10533 Suppress unmodified in-out parameter warning in some cases
10534 This patch is a also fairly significant change to the way suppressible
10535 checks are handled.
10537 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10538 needed for access to concurrent record types generated by the expander.
10539 (Generate_Range_Check): When generating a temporary to capture the
10540 value of a conversion that requires a range check, set the type of the
10541 temporary before rewriting the node, so that the type is always
10542 properly placed for back-end use.
10543 (Apply_Float_Conversion_Check): Handle case where the conversion is
10545 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10546 for a protected type in order to examine its discriminants.

10550 Ed Schonberg <schonberg@adacore.com>
10551 Thomas Quinot <quinot@adacore.com>
10553 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10554 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10555 tests optimized out.
10557 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10558 (Get_Allocator_Final_List): For the case of an anonymous access type
10559 that has a specified Associated_Final_Chain, do not go up to the
10561 (Expand_N_Type_Conversion): Test for the case of renamings of access
10562 parameters when deciding whether to apply a run-time accessibility
10564 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10565 aggregate code before allocator, and ahead of declaration for
10566 temporary, to prevent access before elaboration when the allocator is
10567 an actual for an access parameter.
10568 (Expand_N_Type_Conversion): On an access type conversion involving an
10569 access parameter, do not apply an accessibility check when the
10570 operand's original node was an attribute other than 'Access. We now
10571 create access conversions for the expansion of 'Unchecked_Access and
10572 'Unrestricted_Access in certain cases and clearly accessibility should
10573 not be checked for those.
10575 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10576 includes a type conversion of a packed component that has been expanded,
10577 recover the original expression for the object, and use this expression
10578 in the post-call assignment statement, so that the assignment is made
10579 to the object and not to a back-end temporary.
10580 (Freeze_Subprogram): In case of primitives of tagged types not defined
10581 at the library level force generation of code to register the primitive
10582 in the dispatch table. In addition some code reorganization has been
10583 done to leave the implementation clear.
10584 (Expand_Call): When expanding an inherited implicit conversion,
10585 preserve the type of the inherited function after the intrinsic
10586 operation has been expanded.
10588 * exp_ch2.ads, exp_ch2.adb
10589 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10590 of an entry formal appearing in an assignment statement does not assign
10592 (Expand_Current_Value): Instead of calling a routine to determine
10593 whether the prefix of an attribute reference should be optimized or
10594 not, prevent the optimization of such prefixes all together.
10596 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10597 component whose prefix is known to be of an access type is an implicit
10598 dereference and does not assign to the prefix.
10600 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10601 Robert Dewar <dewar@adacore.com>
10603 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10604 itype is visited, make an entry into table to link associated node and
10606 Add comments and correct harmless error in Build_NCT_Hash_Tables
10607 (Array_Aggr_Subtype): Associate each itype created for an index type to
10608 the corresponding range construct, and not to the aggregate itself. to
10609 maintain a one-to-one correspondence between itype and its associated
10610 node, to prevent errors when complex expression is copied.
10611 Fix mishandling of multiple levels of parens
10613 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10614 treatment of limited views uniform for all visible declarations in a
10615 limited_withed package.
10616 (New_Copy_Tree): If hash table is being used and itype is visited,
10617 make an entry into table to link associated node and new itype.
10618 (Resolve_Record_Aggregate): Do not add an others box association for a
10619 discriminated record component that has only discriminants, when there
10620 is a box association for the component itself.
10622 * par-ch4.adb: Fix mishandling of multiple levels of parens
10624 2007-08-14 Robert Dewar <dewar@adacore.com>
10626 * comperr.adb: Fix problem with suppressing warning messages from gigi
10628 * erroutc.ads, erroutc.adb, errout.ads,
10629 errout.adb (Write_Eol): Remove trailing spaces before writing the line
10630 (Write_Eol_Keep_Blanks): New procedure to write a line, including
10631 possible trailing spaces.
10632 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
10633 Fix problem with suppressing warning messages from back end
10634 Improve handling of deleted warnings
10637 Fix problem with suppressing warning messages from back end
10638 Handle setting of Static_Dispatch_Tables flag.
10641 Fix problem with suppressing warning messages from back end
10643 * exp_intr.adb: Improve handling of deleted warnings
10645 2007-08-14 Robert Dewar <dewar@adacore.com>
10647 * debug.adb: Improve -gnatdI to cover all cases of serialization
10648 Add documentation of dZ, d.t

10658 Gary Dismukes <dismukes@adacore.com>
10660 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10661 to make treatment of limited views uniform for all visible declarations
10662 in a limited_withed package.
10663 Improve warnings for in out parameters
10664 (Set_Related_Interaface/Related_Interface): Allow the use of this
10665 attribute with constants.
10666 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10667 Warn on duplicate pragma Preelaborable_Initialialization
10669 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10670 generation of a freezing node to ensure proper management of null
10671 excluding access types in the backend.
10672 (Create_Extra_Formals): Test base type of the formal when checking for
10673 the need to add an extra accessibility-level formal. Pass the entity E
10674 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10675 originally being done in a couple of cases), to ensure that the
10676 Extra_Formals list gets set on the entity E when the first entity is
10678 (Conforming_Types): Add missing calls to Base_Type to the code that
10679 handles anonymous access types. This is required to handle the
10680 general case because Process_Formals builds internal subtype entities
10681 to handle null-excluding access types.
10682 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10683 functions that need it, even when not marked Requires_Overriding.
10684 Improve warnings for in out parameters
10685 (Analyze_Function_Return): Warn for disallowed null return
10686 Warn on return from procedure with unset out parameter
10687 Ensure consistent use of # in error messages
10688 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10689 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10690 the implicit conversion of the expression done for anonymous access
10691 types. This is required to generate the code of the null excluding
10692 check (if required).
10694 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10695 A formal parameter is never publicly referenceable outside of its body.
10696 (Check_References): For an unreferenced formal parameter in an accept
10697 statement, use the same warning circuitry as for subprogram formal
10699 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10700 Output_Unreferenced_Messages, containing the part of that routine that
10701 is now reused for entry formals as described above.
10702 (Goto_Spec_Entity): New function
10703 (Check_References): Do not give IN OUT warning for dispatching operation
10704 Improve warnings for in out parameters
10705 (Test_Ref): Check that the entity is not undefinite before calling
10706 Scope_Within, in order to avoid infinite loops.
10707 Warn on return from procedure with unset out parameter

10714 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10715 (Expand_N_Attribute_Reference): Further unify the handling of the
10716 three forms of access attributes, using common code now for all three
10717 cases. Add a test for the case of applying an access attribute to
10718 an explicit dereference when the context is an access-to-interface
10719 type. In that case we need to apply the conversion to the prefix
10720 of the explicit dereference rather than the prefix of the attribute.
10721 (Attribute_Version, UET_Address): Set entity as internal to ensure
10722 proper dg output of implicit importation.
10723 (Expand_Access_To_Type): Removed.
10724 (Expand_N_Attribute_Reference): Merge the code from the three cases
10725 of access attributes, since the processing is largely identical for
10726 these cases. The substantive fix here is to process the case of a
10727 type name prefix (current instance case) before handling the case
10728 of interface prefixes.

10735 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10736 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10737 type that is an anonymous access to controlled object, establish
10738 an associated finalization chain to avoid corrupting the global
10739 finalization list when a dynamically allocated object designated
10740 by such a component is deallocated.
10741 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10742 functions that need it, even when not marked Requires_Overriding.
10743 (Initialize_Tag): Replace call to has_discriminants by call to
10744 Is_Variable_Size_Record in the circuitry that handles the
10745 initialization of secondary tags.
10746 (Is_Variable_Size_Record): New implementation.
10747 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10748 Suppress_Initialization pragma for a derived type.
10749 (Is_Variable_Size_Record): New subprogram.
10750 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10751 initial version of this routine and also fixes problems causing
10752 incomplete initialization of the table of interfaces.
10753 (Build_Init_Procedure): Improve the generation of code to initialize the
10754 the tag components of secondary dispatch tables.
10755 (Init_Secondary_Tags): New implementation that simplifies the previous
10756 version of this routine.
10757 (Make_DT): Add parameter to indicate when type has been frozen by an
10758 object declaration, for diagnostic purposes.
10759 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10760 diagnose attemps to freeze a subprogram when some untagged type of its
10761 profile is a private type whose full view has not been analyzed yet.
10762 (Freeze_Array_Type): Generate init proc for packed array if either
10763 Initialize or Normalize_Scalars is set.
10764 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10765 constructing the new profile, copy the null_exclusion indicator for each
10766 parameter, to ensure full conformance of the new body with the spec.
10768 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10769 Create wrappers for constructor functions that need it, even when not
10770 marked Requires_Overriding.
10771 (Covers): Handle properly designated types of anonymous access types,
10772 whose non-limited views are themselves incomplete types.
10773 (Add_Entry): Use an entity to store the abstract operation which hides
10775 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10776 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10777 initialization aggregate.
10778 (Function_Interp_May_Be_Hidden): Rename to
10779 Function_Interp_Has_Abstract_Op.
10780 (Has_Compatible_Type): Remove machinery that skips interpretations if
10781 they are labeled as potentially hidden by an abstract operator.

10804 the proper body of a stub.
10805 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10806 of the same dispatch table slot to renamed primitives.
10807 (Make_Select_Specific_Data_Table): Handle private types.
10808 (Tagged_Kind): Handle private types.
10809 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10810 output of implicit importation and exportation.
10811 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10812 first formal of the thunk is always associated with the controlling
10813 type. In addition perform the following code cleanup: remove formal
10814 Thunk_Alias which is no longer required, cleanup evaluation of the
10815 the controlling type, and update the documentation.
10816 Replace occurrence of Default_Prim_Op_Count by
10817 Max_Predef_Prims. Addition of compile-time check to verify
10818 that the value of Max_Predef_Prims is correct.
10819 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10820 (Make_DT): Add parameter to indicate when type has been frozen by an
10821 object declaration, for diagnostic purposes.
10822 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10823 construction of statically allocated dispatch tables.
10824 (Make_DT): In case of library-level tagged types export the declaration

10827 tables. Take care of building tables for asynchronous interface types
10828 (Make_Tags): New subprogram that generates the entities associated with
10829 the primary and secondary tags of Typ and fills the contents of Access_
10830 Disp_Table. In case of library-level tagged types imports the forward
10831 declaration of the primary tag that will be declared later by Make_DT.

10840 * exp_util.ads, exp_util.adb:
10841 This patch replaces a number of occurrences of explicit tests for N_Null
10842 with calls to Known_Null. This improves tracking of null values, since
10843 Known_Null also catches null constants, and variables currently known to
10844 be null, so we get better tracking.
10845 (Ensure_Defined): create an itype reference only in the scope of the
10847 (Side_Effect_Free): A selected component of an access type that
10848 denotes a component with a rep clause must be treated as not
10849 side-effect free, because if it is part of a linked structure its
10850 value may be affected by a renaming.
10851 (Expand_Subtype_From_Expr): For limited objects initialized with build
10852 in place function calls, do nothing; otherwise we prematurely introduce
10853 an N_Reference node in the expression initializing the object, which
10854 breaks the circuitry that detects and adds the additional arguments to
10855 the called function. Bug found working in the new patch for statically
10856 allocated dispatch tables.
10857 (Is_Library_Level_Tagged_Type): New subprogram.
10858 (Remove_Side_Effects): If the expression of an elementary type is an
10859 operator treat as a function call.
10860 (Make_Literal_Range): If the index type of the array is not integer, use
10861 attributes properly to compute the constraint on the resulting aggregate
10864 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10865 class-wide type whose base type is an incomplete private type, leave
10866 class-wide type unfrozen so that freeze nodes can be generated
10867 properly at a later point.
10868 (Freeze_Entity, array case): Handle case of pragma Pack and component
10869 size attributre clause for same array.

11497 (Set_Item): When the new item is an element of the currently allocated
11498 table passed by reference, save a copy on the stack if we're going

11515 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11516 derived type with interface progenitors use the analyzed formal as the
11517 parent of the actual, to create renamings for all the inherited
11518 operations in Derive_Subprograms.
11519 (Collect_Previous_Instances): new procedure within of
11520 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11521 unit being loaded, to ensure that the generation of global symbols is
11522 consistent in different compilation modes.
11523 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11524 takes progenitor types into account.
11525 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11526 traversing over the primitives of the formal and actual types to locate
11527 any abstract subprograms of the actual type that correspond to a
11528 nonabstract subprogram of the formal type's ancestor type(s), and issue
11529 an error if such is found.
11530 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11531 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11532 Remove bogus guard around calls to Inherit_Context.
11533 (Reset_Entity): If the entity is the selector of a selected component

11537 a predefined or internal unit.
11539 2007-08-14 Ed Schonberg <schonberg@adacore.com>

11542 parameter to determine whether operation applies to the prefix.
11543 (Complete_Object_Operation): If actual has an access type and
11544 controlling formal is not an in_parameter, reject the actual if it is
11545 an access_to_constant type.
11546 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11547 type, the candidate operations are found in the scope of declaration of
11548 the type, because the type has no primitive subprograms.
11549 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11550 a private extension, only examine visible components before trying to
11551 analyze as a prefixed call.
11552 Change Entity_List to Type_To_Use, for better readability.
11553 (Has_Fixed_Op): Use base type when checking whether the type of an
11554 operator has a user-defined multiplication/division

11562 formal At_Any_Place indicating, when True, that we want to test for
11563 availability of the stream attribute at any place (as opposed to the
11564 current visibility context only).
11565 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11566 purpose of enforcing E.2.2(8) only if it is not available at any place.
11567 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11568 when checking the legality of an extension aggregate in a preelaborable
11569 package. Treat the literal null as a valid default expression in a
11570 component declaration for a type with preelaborable initialization.
11571 A limited interface is a legal progenitor for the designated type of a
11572 remote access to class-wide type.

11584 mark the full view as referenced, to prevent spurious warnings.
11585 (Find_Selected_Component, Has_Components): Handle properly non-limited
11586 views that are themselves incomplete types.
11587 Handle interfaces visible through limited-with clauses.
11588 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11589 subprogram generic actual for which we have generated a renaming.
11590 Warn when the renaming introduces a homonym of
11591 the renamed entity, and the renamed entity is directly visible.

11599 (Resolve_Allocator): Perform cleanup if resolution has determined that
11600 the allocator is not a coextension.
11601 (Resolve): Skip an interpretation hidden by an abstract operator only
11602 when the type of the interpretation matches that of the context.
11603 (Resolve): When looping through all possible interpretations of a node,
11604 do not consider those that are hidden by abstract operators.
11605 (Resolve_Actuals): When verifying that an access to class-wide object
11606 is an actual for a controlling formal, ignore anonymous access to
11607 subprograms whose return type is an access to class_wide type.
11608 (Resolve_Slice): If the prefix of the slice is a selected component
11609 whose type depends on discriminants, build its actual subtype before
11610 applying range checks on the bounds of the slice.
11611 (Valid_Conversion): In an instance or inlined body, compare root types,
11612 to prevent anomalies between private and public views.
11613 (Resolve): Improve error message for ambiguous fixed multiplication
11614 expressions that involve universal_fixed multiplying operations.

11634 elabration statements, register the package with the name server
11635 at the beginning, not at the end, of the elaboration statements so
11636 that they can create remote access to subprogram values that designate
11637 remote subprograms from the package.

12726 Zero_Formatting is set.
12727 Add case for CLI_Target.

12766 bounds of the slice to construct the required constraint checks.
12767 Improve NOT NULL error messages
12768 (Apply_Constraint_Check): If the context is a null-excluding access
12769 type, diagnose properly the literal null.

12785 Arnaud Charlet <charlet@adacore.com>
12787 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12788 applicable to types that have the With_Type flag set. Returns the
12789 non-limited view of the type, if available, otherwise the type itself.
12790 For class-wide types, there is no direct link in the tree, so we have
12791 to retrieve the class-wide type of the non-limited view of the Etype.
12792 New attributes Static_Initialization and Static_Elaboration_Desired.
12793 Remove the pragma Thread_Body, and the associated flag
12794 Is_Thread_Body in entities, and all related code.

12808 (Root_Type): Handle properly subtypes of class-wide-types.
12811 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12812 class-wide types visible through limited-with clauses.
12813 (Try_Primitive_Operation): When examining all primitive operations of a
12814 tagged type, do not consider subprograms labeled as hidden unless they
12815 belong to a private generic type with a tagged parent.
12816 (Try_Object_Operation): Extensive rewriting, to handle properly various
12817 overloading cases, when several ancestors may have class-wide operations
12818 that are possible candidates, and when the overloaded functions return
12819 array types and have defaulted parameters so that the call may be
12820 interpreted as an indexing.
12821 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12822 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12823 successive actuals before analyzing the call itself.
12824 (Try_Primitive_Operation): A primitive operation is compatible with the
12825 prefix if the prefix has a synchronized type and the type of the formal
12826 is its corresponding record, as can be the case when the primitive
12827 operation is declared outside of the body of the type.
12828 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12829 perform homonym traversal, looking for class-wide operation matches
12830 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12831 access parameters are now restricted to anonymous access types.
12832 (Mark_Allocator): An allocator with a discriminant association parent is
12834 (Try_One_Prefix_Interpretation): If the type of the object is
12835 incomplete, as can be happen when it is a limited view obtained through
12836 a limited_with_clause, the selected component is not part of a prefixed
12838 (Complete_Object_Operation): Diagnose properly an object that is not
12839 aliased when the corresponding controlling formal is an access
12841 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12842 ambiguous calls in prefixed notation, where two primitives differ only
12843 in that the controlling argument of one is an access parameter.
12845 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12846 whether a function that returns an unconstrained type can be inlined.
12847 (Process_Formals): Diagnose properly the illegal use of an incomplete
12848 type in the profile of an access_to_subprogram declaration.
12849 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12850 operations are attached to the corresponding record.
12851 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12852 When processing a primitive of a concurrent type which implements an
12853 interface change the type of all controlling formals to that of the
12854 corresponding record type.
12855 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12856 to determine the tagged type to which a primitive belongs.
12857 (Check_Conventions): Capture condition to ignore a primitive operation
12858 (which is shared between the loop in Check_Conventions and the one in
12859 Check_Convention) in a new local function Skip_Check.
12860 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12861 confusion with Check_Conventions' own Prim_Op local variable.
12862 (Create_Extra_Formals): Test for a tagged result type rather than a
12863 controlling result when determining whether to add a BIP_Alloc_Form
12864 formal and a BIP_Final_List formal to the function.
12865 (Check_Conformance); For parameters that are anonymous access types,
12866 subtype conformance requires that the not null and the constant
12867 indicators must match
12868 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12869 to retrieve the appropriate type when processing a concurrent type
12870 declared within a generic. Minor comment reformatting. Change invocation
12871 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12873 (Analyze_Subprogram_Body): If the return type of a function is an
12874 anonymous access to the limited view of a class-wide type, and the
12875 non-limited view of the type is available, update the type of the
12876 function so that code can be generated.
12877 (Process_Formals): In case of access-subtype itype whose designated
12878 type is also an itype (situation that happens now with access to
12879 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12880 attribute to avoid backend problems.
12881 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12882 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12883 anonymous types' designated types are same before testing
12884 Subtypes_Statically_Match.
12885 (Create_Extra_Formals): Test for a named access parameter that is a
12886 controlling formal as an additional condition for adding an
12887 accessibility level formal. This can occur in the subp type created for
12888 dispatching calls in Expand_Dispatching_Call, and allows calling
12889 Create_Extra_Formals from that procedure rather than special-casing the
12890 extra formals there.
12891 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12892 when the function has a controlling result.
12893 (Check_Returns): Add much more knowledge of the optimization of local
12894 raise statements to gotos, to retain proper warnings in this case.
12895 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12896 nodes when looking for last statement.
12898 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12899 class-wide types visible through limited with clauses.
12900 (Add_One_Interp): If the operands are anonymous access types, the
12901 predefined operator on universal_access is immediately visibles
12902 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12903 other anonymous access types.
12904 (Disambiguate): Take into account CIL convention.
12905 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

12925 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12926 in extension aggregates.
12927 (Flatten): Other conditions being met, an aggregate is static if the
12928 low bound given by component associations is different from the low
12929 bound of the base index type.
12930 (Packed_Array_Aggregate_Handled): If the component type is itself a
12931 packed array or record, the front-end must expand into assignments.
12932 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12933 Init_Pr, instead of Ancestor_Is_Expression.
12934 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12935 coextension chain root, either generate a list controller or use the
12936 already existing one.
12937 (Static_Array_Aggregate): New procedure to construct a positional
12938 aggregate that can be handled by the backend, when all bounds and
12939 components are compile-time known constants.
12940 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12941 types covering interface types into assignments.
12942 (Replace_Type): move to Build_Record_Aggr_Code.
12943 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12944 interface type, convert to the definite type of the aggregate itself,
12945 so that needed components are visible.
12946 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12947 components and the context is an extended return statement do not
12948 create a transient block for it, to prevent premature finalization
12949 before the return is executed.
12950 (Gen_Assign): Do not generate a call to deep adjust routine if the
12951 component type is itself an array of controlled (sub)-components
12952 initialized with an inner aggregate.
12953 (Component_Check): New name for Static_Check. This name is now more
12954 appropriate, and documentation is added which was missing.
12955 (Component_Check): Add test for bit aligned component value
12956 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12957 Tagged_Comps, name is more appropriate given added function below.

12962 Robert Dewar <dewar@adacore.com>
12964 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12965 Terminated: Add unchecked type conversion from System.Address to
12966 System.Tasking.Task_Id when calling the predefined primitive
12968 Disable new Ada 05 accessibility check for JVM.NET targets, which
12969 cannot be implemented in a practical way.
12970 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12971 the sources always references the tag of the actual object. Therefore,
12972 if 'Tag is applied in the sources to class-wide interface objects we
12973 generate code that displaces "this" to reference the base of the object.
12974 (Expand_N_Attribute_Reference, case Size): Return specified size if
12975 known to front end.
12976 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12977 has code that displaces the pointer of the object to manage interface
12978 types. However this code must not be executed when the prefix is a
12979 subprogram. This bug caused the wrong expansion of the internally
12980 generated assignment that fills the dispatch table when the primitive
12981 is a function returning a class-wide interface type.
12982 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12983 Set_Attribute_Name for Name_Unaligned_Valid.

12988 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12989 If the initialization is the equivalent aggregate of the initialization
12990 procedure of the type, do not remove it.
12991 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12992 initialized to null from having their expression reset to empty and
12993 note this exception in the comment.

13001 Add "with" and "use" clauses for Sem_Attr.
13002 (Expand_Current_Value): Do not replace occurences of attribute
13003 references where the prefix must be a simple name.
13005 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13006 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13007 Attribute_Requires_Simple_Name_Prefix.
13008 (Name_Modifies_Prefix): Body of new function.
13009 (Requires_Simple_Name_Prefix): Body of new function.
13010 (Resolve_Attribute, case Access): Improve error message for case of
13011 mismatched conventions.
13012 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13014 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13015 constrained subtype for a nominal unconstrained type, use its base type
13016 to check for conformance with the context.
13017 (Resolve_Attribute): Remove test of the access type being associated
13018 with a return statement from condition for performing accessibility
13019 checks on access attributes, since this case is now captured by
13020 Is_Local_Anonymous_Access.
13021 (Analyze_Access_Attribute): Set Address_Taken on entity
13022 (Analyze_Attribute, case Address): Set Address_Taken on entity
13023 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13024 validating an access attribute whose prefix is a current instance.
13025 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13026 applied to dispatching operations, if freezing is required then we set
13027 the attribute Has_Delayed_Freeze in the prefix's entity.
13028 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13029 current scope if access of local subprogram taken
13030 (Analyze_Access_Attribute): Check legality of self-reference even if the
13031 expression comes from source, as when a single component association in
13032 an aggregate has a box association.
13033 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13034 the prefix if it is a protected operation and the attribute is
13035 Unrestricted_Access.
13036 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13037 reference to the base type of the context, to force a constraint check
13038 when the context is an access subtype with an explicit constraint.
13039 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13040 node is rewritten as an interface conversion. leave unanalyzed after
13041 resolution, to ensure that type checking against the context will take

13046 Robert Dewar <dewar@adacore.com>
13048 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13049 wrapper when the full view of the controlling type of an inherited
13050 function that dispatches on result implements interfaces.
13051 (Expand_N_Object_Declaration): In cases where the type of the
13052 declaration is anonymous access, create finalization list for it.
13053 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13054 if the object has no explicit initialization, to match description of
13055 functionality of pragam Persistent_BSS.
13056 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13057 new function to build static aggregates, to replace initialization call
13058 when static initialization is desired.
13059 (Freeze_Type): Generate a list controller for an access type whenever
13060 its designated type has controlled anonymous access discriminants.
13061 (Build_Equivalent_Aggregate): New procedure to compute a static
13062 aggregate to be used as default initialization for composite types,
13063 instead of a generating a call to the initialization procedure for the
13065 (Build_Initialization_Call): When available, replace a call to the
13066 initialization procedure with a copy of the equivalent static aggregate
13068 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13069 declarations for objects of a class-wide interface type, rather than
13070 just identifiers, to prevent visibility problems.
13071 (Expand_N_Object_Declaration): When expanding the declaration for an
13072 object of a class-wide interface type, preserve the homonym chain of
13073 the original entity before exchanging it with that of the generated
13074 renaming declaration.
13075 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13076 active, because there is no way to handle the exception.
13077 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13078 to do a minimum decoration of the Access_Disp_Table list.
13079 (Expand_Record_Controller): Avoid the addition of the controller between
13080 the component containing the tag of a secondary dispatch table and its
13081 adjacent component that stores the offset to the base of the object.
13082 This latter component is only generated when the parent type has
13083 discriminants ---documented in Add_Interface_Tag_Components).
13084 (Apply_Array_Size_Check): Removed, no longer needed.
13085 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13086 components, create a Master_Entity for it only if it contains tasks.
13087 (Build_Init_Procedure): Suppress the tag assignment compiling under
13089 (Freeze_Record_Type): Remove code associated with creation of dispatch
13091 (Init_Secondary_Tags): Update type of actuals when generating calls to
13092 Ada.Tags.Set_Offset_To_Top
13093 (Stream_Operation_OK): Disable use of streams compiling under no
13095 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13096 if Has_Init_Expression set.
13097 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13098 Register_Primitive, which provides the same functionality.
13099 (Requires_Init_Proc): Return false in case of interface types.
13100 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13102 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13103 is always associated with a predefined primitive because the internal
13104 entities associated with interface types are not predefined primitives.
13105 Therefore, the call to Is_Internal is replaced by a call to the
13106 function Is_Predefined_Dispatching_Operation.
13107 (Make_Eq_If): When generating the list of comparisons for the
13108 components of a given variant, omit the controller component that is
13109 present if the variant has controlled components.

13113 Bob Duff <duff@adacore.com>
13115 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13116 handle the creation of finalization lists and calls for nested
13117 coextensions when the root of the chains is part of a return statement.
13118 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13120 (Expand_Record_Equality): Skip components that are interface types.
13121 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13122 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13123 with Rewrite_Coextension. Change the condition for detecting coextension
13125 (Is_Local_Access_Discriminant): Removed.
13126 (Rewrite_Coextension): New routine which rewrites a static coextension
13127 as a temporary and uses its unrestricted access in the construction of
13129 (Complete_Coextension_Finalization): New routine. Generate finalization
13130 attachment calls to all delayed coextensions.
13131 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13132 the allocator is not a coextension itself and has delayed coextensions.
13133 If the current allocator is controlled, but also a coextension, delay
13134 the generation of the finalization attachment call.
13135 Rename local variable "Node" to "Nod" in order to avoid confusion with
13137 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13138 limited types that are not inherently limited. Such an allocator is
13139 illegal, but is generated by the expander for a return statement, to
13140 copy the result onto the secondary stack. This is the only case where a
13141 limited object can be copied. Generate code to displace the pointer
13142 to the object if the qualified expression is a class-wide interface
13143 object. Such displacement was missing and hence the copy of the object
13145 (Apply_Accessibility_Check): Handle allocated objects initialized in
13147 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13148 and Expand_Allocator_Expression. Allocating class-wide interface objects
13149 this routine displaces the pointer to the allocated object to reference
13150 the component referencing the corresponding secondary dispatch table.
13151 Expand_Allocator_Expression): Add missing support to allocate class-wide
13152 interface objects initialized with a qualified expression.
13153 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13154 function result type, and use the finalization list associated with the
13155 function scope in that case (such an anonymous type should not be
13156 treated like an access parameter's type).

13159 Gary Dismukes <dismukes@adacore.com>
13160 Javier Miranda <miranda@adacore.com>
13162 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13163 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13164 required exception handler.
13165 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13166 properly the case of a function whose return type is a limited
13167 class-wide interface type. Modify the code of the accessibility
13168 check to handle class-wide interface objects. In this case we need to
13169 displace "this" to reference the primary dispatch table to get access
13170 to the TSD of the object (to evaluate its accessibility level).
13171 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13172 rather than a controlling result as one of the conditions for
13173 generating tests of the implicit BIP_Alloc_Form formal. The
13174 initialization assignment is also handled according to whether the
13175 result is tagged instead of controlling.
13176 In the case where the init assignment is inserted in the "then" part of
13177 the allocation conditional, rewrite the target to be a dereference of
13178 the implicit BIP_Object_Access formal.
13179 If the returned value is unconstrained and created on the secondary
13180 stack, mark the enclosing block and function so that the secondary
13181 stack is not reclaimed on return.
13182 Treat returns from functions with controlling results similarly to
13183 returns from functions with unconstrained result subtypes.
13184 If the object returned is unconstrained, and an allocator must be
13185 created for it, analyze the allocator once the block for the extended
13186 return is installed, to ensure that finalizable components
13187 of the expression use the proper finalization list. Guard the call to
13188 Move_Final_List with a check that there is something to finalize.
13189 (Make_Tag_Ctrl_Assignment): Use "old" handling
13190 of controlled type assignment for virtual machines, since new code uses
13191 unsupported features (such as direct access to bytes in memory).

13194 Ed Schonberg <schonberg@adacore.com>
13196 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13197 accessibility actual, check for the case of an aliased object that has
13198 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13199 we fall into processing for the attribute rather than the name of the
13201 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13202 formal has its address taken in the body, create a temporary to capture
13203 value. If the return type is a limited interface, do not treat the
13204 return value as Controlled.
13205 (Is_In_Place_Function): If the return type is a limited interface,
13206 treat as returning in place. The actual returned object may not always
13207 be limited, but the caller has to assume that it is returned in place.
13208 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13209 context of an allocator, use the correct finalization chain (that is,
13210 the chain belonging to the access type, rather than the chain belonging
13211 to the current scope).
13212 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13213 result type rather than a controlling result as a precondition for
13214 adding an allocation form actual to a build-in-place call.
13215 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13216 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13217 primitive in the dispatch tables. This work is now done by Make_DT when
13218 the type is frozen.
13219 (Register_Predefined_DT_Entry): Removed.
13220 (Add_Return): If end label is not present, use sloc of last statement
13221 for generated return statement in procedure, for better gdb behavior
13223 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13224 object address nodes to ensure proper processing by routines like
13226 (Expand_Call): Fix generation of validity check for parameter
13227 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13228 the allocation form parameter if the result subtype is constrained,
13229 except when the function has a controlling result.
13230 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13231 rather than Is_Controlled and Has_Controlled_Component, since we want to
13232 include class-wide result types in this treatment. Also test for a
13233 controlling result, since that also requires passing a finalization
13235 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13236 even when the result subtype is constrained, to handle calls involving
13237 controlling results.
13238 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13239 is now called even when the result subtype is constrained, to handle
13240 calls involving controlling results.
13241 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13242 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13243 now performs the test).
13244 (Make_Build_In_Place_Call_In_Object_Declaration):
13245 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13246 constrained, to handle calls involving controlling results.
13247 (Add_Return): Accomodate rewritten pattern from local raise to goto
13248 transformation, so that we still recognize an transfer statement
13249 and do the right thing here in that case.
13250 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13251 and end of subprogram code.
13252 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13253 support for primitives that are functions (without formals) with a
13254 controlling result.
13255 (Inherited_From_Formal): If the actual subtype has not generic parent
13256 type, it is not an actual for a formal derived type, and there is no
13257 operation to inherit from the formal.

13260 Thomas Quinot <quinot@adacore.com>
13262 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13263 inserted cleanup code appropriately for GDB use.
13264 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13265 exception handler for Deep_Adjust or Deep_Finalize.
13266 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13267 Raise_From_Controlled_Operation is available, use a call to that
13268 subprogram instead of a plain "raise Program_Error" node to raise
13269 Program_Error if an exception is propagated from an Adjust or Finalize
13271 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13272 appears in the optional statement list of a triggering alternative, the
13273 scope actions can be inserted directly there, and not in the list that
13274 includes the asynchronous select itself.

13280 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13281 generated exception handler appropriately when debugging generated code.
13282 Deal properly with No_Exception_Propagation restriction mode.
13283 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13284 System.Address to System.Tasking.Task_Id when processing the result of
13285 the predefined primitive _disp_get_task_id.
13286 (Expand_N_Asynchronous_Select): Clarify comment.
13287 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13288 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13289 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13290 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13291 privals and for generated call to Complete_Entry_Body, for better gdb
13293 (Copy_Result_Type): Utility to construct a parameter and result profile
13294 for protected functions whose return type is an anonymous access to
13296 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13298 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13299 point when the local-raise-to-goto transformation has taken place.
13301 2007-06-06 Javier Miranda <miranda@adacore.com>
13302 Nicolas Setton <setton@adacore.com>
13304 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13305 functionality when the backend is generating code.
13306 Otherwise any serious error
13307 reported by the backend calling the frontend routine Error_Msg
13308 changes the Compilation_Mode to Check_Semantics, disables the
13309 functionality of this routine and causes the generation of
13310 spureous additional errors.
13312 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13313 debugging information now generated by the compiler for fat-pointer
13315 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13317 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13319 2007-06-06 Thomas Quinot <quinot@adacore.com>
13321 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13322 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13323 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13324 For a remote call to a function with a classwide return type, apply an
13325 E.4(18) check to the returned value.
13326 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13327 stream attributes of the designated type of an RACW, as they are not
13328 dispatching primitive operations.
13330 2007-06-06 Geert Bosch <bosch@adacore.com>
13332 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a

13344 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13346 2007-06-06 Javier Miranda <miranda@adacore.com>
13348 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13349 deallocation of class-wide interface objects.
13350 (Expand_Dispatching_Constructor_Call): Take into account that if the
13351 result of the dispatching constructor is an interface type, the
13352 function returns a class-wide interface type; otherwise the returned
13353 object would be actual. The frontend previously accepted returning
13354 interface types because Expand_Interface_Actuals silently performed
13355 the management of the returned type "as if" it were a class-wide
13357 (Expand_Dispatching_Constructor_Call): Replace call to
13358 Make_DT_Access_Action by direct call to Make_Function_Call.

13361 Ed Schonberg <schonberg@adacore.com>
13363 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13364 compute masking constant, since we now set Esize properly to the
13366 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13367 to match the alignment.
13368 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13369 packed arrays of 8 bits or less.
13371 * freeze.adb (Freeze_Entity): When freezing the formals of a
13372 subprogram, freeze the designated type of a parameter of an access type
13373 only if it is an access parameter.
13374 Increase size of C convention enumeration object
13375 (Freeze_Entity, array type case): Make sure Esize value is properly
13376 adjusted for the alignment if it is known.
13377 (Freeze_Entity, array type case): When checking bit packed arrays for
13378 the size being incorrect, check RM_Size, not Esize.
13379 (Freeze_Record_Type): Check for bad discriminated record convention
13380 (In_Exp_Body): Return true if the body is generated for a subprogram
13381 renaming, either an attribute renaming or a renaming as body.
13382 (Check_Itype): If the designated type of an anonymous access component
13383 is a non-protected subprogram type, indicate that it is frozen, to
13384 prevent out-of-scope freeze node at some subsequent call.
13385 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13386 only if the subprogram is neither imported nor exported, as well as the
13387 NCA descriptor class if the subprogram is exported.

13395 default initialization on an imported object, when there is no
13396 initialization call generated for it.
13397 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13400 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13401 Static_Elaboration_Desired.
13402 Remove pragma Thread_Body.
13403 Implement a new pragma No_Body
13404 Removes the Explicit_Overriding pragma
13405 Remove Optional_Overriding pragma
13406 (Prag): Deal with Universal_Aliasing.
13407 (Name_CIL, Name_CIL_Constructor, Convention_CIL,

13977 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
13978 associated with dispatch tables is known at compile time.
13979 (Get_Value): If an association in a record aggregate has a box
13980 association, and the corresponding record component has a default
13981 expression, always copy the default expression, even when the

15420 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15421 when -gnatg is not specified.

15451 (Convert_Aggr_In_Allocator): If the allocator is for an access
15452 discriminant and the type is controlled. do not place on a finalization
15453 list at this point. The proper list will be determined from the

15473 parameter of the containing subprogram.
15474 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15475 under No_Dispatching_Calls restriction. During the semantic analysis
15476 we already notified such violation.

15647 statements in the HSS at the end of the pacakge.
15648 When expanding a package spec, this list correspond to the
15650 (Add_Receiving_Stubs_To_Declarations): Append the function
15651 registering the receiving stubs at the end of the 'Stmts' list.
15652 (RCI_Package_Locator): Pass the new Version generic formal when
15653 instantiating a RCI_Locator package.
15654 (Build_From_Any_Function): To compute the High bound for an
15655 unconstrained array actual, we add the Low bound with the length.
15656 Thus we must convert the low bound and the length to an appropriate
15657 type before doing the sum.
15658 (Build_Subprogram_Receiving_Stubs, PolyORB):
15659 * Retrieve the extra formals parameters at the
15660 end of the parameter stream.
15661 * Use Move_Any_Value to write back out parameters
15662 after executing the request as it is more efficient
15663 than Copy_Any_Value.
15664 * Build the any containing Extra Formals with the
15665 appropriate typecode.
15666 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15667 empty Component_List.
15668 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15669 the tree the declaration for an object that serves as actual parameter
15670 in server-side stubs.
15671 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15672 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15673 Use Build_Actual_Object_Declaration to prepare the actuals.
15674 (Add_Parameter_To_NVList): Set the parameter mode to In for
15675 Extra Constrained Parameters.
15676 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15677 Extra Constrained parameters.
15678 (Build_To_Any_Function, Build_From_Any_Function,
15679 Built_TypeCode_Function): When Typ is implicit, call the correct
15680 function with the first not implicit parent type.
15681 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15682 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15683 typecode from the Etype. Therefore we retrieve the correct typecode
15684 with a call to Get_Any_Type.
15685 (Copy_Specification): Do controlling formal type substitution based on
15686 Is_Controlling_Formal flag, instead of caller-provided object type.
15687 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15688 a RACW primitive operation, we might get a subprogram declaration for an
15689 ancestor of the RACW designated type (not for the designated type
15690 itself), in the case where this operation is inherited. In this case we
15691 have no easy means of determining the original tagged type for which
15692 the primitive was declared, so instead we now rely on
15693 Copy_Specification to use the Is_Controlling_Formal flag to determine
15694 which formals require type substitution.

15700 GNAT.Current_Exception are not allowed if pragma Restrictions
15701 (No_Exception_Propagation) is set and in any case make the associated
15702 handler unsuitable as a target for a local raise statement.
15703 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15704 run-time subprogram CW_Membership by call to Build_CW_Membership.
15705 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15706 by a function call, a temporary must be created before expanding the
15707 Constructor_Call itself, to prevent out-of-order elaboration in the
15708 back-end when stack checking is enabled..
15710 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15712 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15713 result are the bounds of the left operand, not the right.
15715 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15718 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

16119 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16120 full word is no longer compared twice.
16122 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16124 * sem_ch10.adb (Install_Limited_Context_Clauses.
16125 Expand_Limited_With_Clause): Use a new copy of selector name in the
16126 call to Make_With_Clause. This fixes the tree structure for ASIS
16127 purposes. Nothing is changed in the compiler behaviour.
16128 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16129 a package renaming.
16130 (Install_Limited_With_Clauses): Do not install non-limited view when it
16131 is still incomplete.
16133 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16134 Gary Dismukes <dismukes@adacore.com>
16136 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16137 when capturing size information, instead of base type, which for a
16138 formal array type will be the unconstrained type.
16139 (Analyze_Formal_Object_Declaration): Add check for illegal default
16140 expressions for a formal in object of a limited type.
16141 (Instantiate_Object): Ditto.
16142 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16143 because they were defaulted in the formal package and no check applies
16145 (Check_Formal_Package_Instance): Extend conformance check to other
16146 discrete types beyond Integer.
16147 (Process_Default): Copy directly the unmatched formal. A generic copy
16148 has already been performed in Analyze_Formal_Package.
16149 (Analyze_Associations): If a formal subprogram has no match, check for
16150 partial parametrization before looking for a default, to prevent
16152 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16153 not set the instantiation environment before analyzing the actuals.
16154 Fixes regression on 8515-003 with implementation of AI-133.
16155 Set_Instance_Env checks whether the generic unit is a predefined
16156 unit, in which case the instance must be analyzed with the latest Ada
16157 mode. This setting must take place after analysis of the actuals,
16158 because the actuals must be analyzed and frozen in the Ada mode extant
16159 outside of the current instantiation.
16160 (Save_Env, Restore_Env): Preserve and restore the configuration
16161 parameters so that predefined units can be compiled in the proper Ada
16163 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16164 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16165 and Is_Abstract_Type.
16166 (Analyze_Formal_Package): For better error recovery, Add exception
16167 handler to catch Instantion_Error, which can be raised in
16168 Analyze_Associations
16170 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16171 Bob Duff <duff@adacore.com>
16172 Gary Dismukes <dismukes@adacore.com>
16174 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16175 prefix type is a discriminated subtype of the type of the formal.
16176 (Analyze_Allocator): Collect all coextensions regardless of the context.
16177 Whether they can be allocated statically is determined in exp_ch4.
16178 (Analyze_Selected_Component): If the prefix is a limited view and the
16179 non-limited view is available, use the non-limited one.
16180 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16181 therefore illegal), suggest a qualified expression rather than a type
16182 conversion, because a type conversion would be illegal in this context.
16183 (Anayze_Allocator): Trace recursively all nested allocators so that all
16184 coextensions are on the corresponding list for the root. Do no mark
16185 coextensions if the root allocator is within a declaration for a stack-
16186 allocated object, because the access discriminants will be allocated on
16188 (Analyze_Call): Remove restriction on calls to limited functions for the
16189 cases of generic actuals for formal objects, defaults for formal objects
16190 and defaults for record components.
16191 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16192 element list. Their expansion is delayed until the enclosing allocator
16193 is processed and its finalization list constructed.
16194 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16195 for an operation with the given name among the primitive operations of
16196 the corresponding record type.
16197 (Analyze_Selected_Component): If the prefix is a task type that
16198 implements an interface, and there is no entry with the given name,
16199 check whether there is another primitive operation (e.g. a function)
16201 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16202 properly the indexing of a function call written in prefix form, where
16203 the function returns an array type, and all parameters of the function
16204 except the first have defaults.
16205 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16206 the original operands, rather than relocating them, for efficiency and
16207 to work properly when an operand is overloaded.
16208 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16209 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16210 (Analyze_Selected_Component): If the prefix is a private extension, only
16211 scan the visible components, not those of the full view.
16212 (Try_Primitive_Operation): If the operation is a procedure, collect all
16213 possible interpretations, as for a function, because in the presence of
16214 classwide parameters several primitive operations of the type can match
16215 the given arguments.
16217 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16218 Robert Dewar <dewar@adacore.com>
16220 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16221 tag-indeterminate call to an abstract function, when the left-hand side
16223 (Analyze_Loop_Statement): Improve detection of infinite loops
16225 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16226 Thomas Quinot <quinot@adacore.com>
16228 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16229 out of Analyze_Package_Declaration, because processing must be applied
16230 to package bodies as well, for deferred constants completed by pragmas.
16231 (Analyze_Package_Declaration): When the package declaration being
16232 analyzed does not require an explicit body, call Check_Completion.
16233 (May_Need_Implicit_Body): An implicit body is required when a package
16234 spec contains the declaration of a remote access-to-classwide type.
16235 (Analyze_Package_Body): If the package contains RACWs, append the
16236 pending subprogram bodies generated by exp_dist at the end of the body.
16237 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16238 Is_Abstract_Subprogram and Is_Abstract_Type.
16239 (Preserve_Full_Attributes): The full entity list is not an attribute
16240 that must be preserved from full to partial view.
16242 * sem_dist.adb (Add_RAS_Dereference_TSS):
16243 Change primitive name to _Call so it cannot clash with any legal
16244 identifier, and be special-cased in Check_Completion.
16245 Mark the full view of the designated type for the RACW associated with
16246 a RAS as Comes_From_Source to get proper view switching when installing
16247 private declarations.
16248 Provite a placeholder nested package body along with the nested spec
16249 to have a place for Append_RACW_Bodies to generate the calling stubs
16250 and stream attributes.
16252 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16253 Robert Dewar <dewar@adacore.com>
16255 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16256 that is a limited view, check the non-limited view if available.
16257 (Undefined): Refine error message for missing with of Text_IO
16258 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16259 to distinguish real missing with cases.
16260 Fix format of all missing with messages
16261 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16262 renaming as body when renamed entity is abstract.
16264 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16265 Javier Miranda <miranda@adacore.com>
16267 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16268 predicate recursive, to handle complex expressions on literals whose
16269 spurious ambiguity comes from the abstract interpretation of some
16271 (Interface_Present_In_Ancestor): Add support to concurrent record
16273 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16274 Is_Abstract_Subprogram and Is_Abstract_Type.
16276 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16277 Javier Miranda <miranda@adacore.com>
16279 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16280 dereference of a local object R created as a reference to another
16281 object O, use the access level of O.
16282 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16283 rather than local Same_Formal_Type, to check whether protected operation
16284 overrides an inherited one.
16285 (Same_Formal_Type): New predicate, used when matching signatures of
16286 overriding synchronized operations, to handle the case when a formal
16287 has a type that is a generic actual.
16288 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16289 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16290 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16291 syntactic ambiguities involving indexing of function calls that return
16293 (Abstract_Interface_List): New subprogram that returns the list of
16294 abstract interfaces associated with a concurrent type or a
16295 concurrent record type.
16296 (Interface_Present_In_Parent): New subprogram used to check if a
16297 given type or some of its parents implement a given interface.
16298 (Collect_Abstract_Interfaces): Add support for concurrent types
16299 with interface types.
16300 (Has_Abstract_Interfaces): Add support for concurrent types with
16302 (Is_Parent): New subprogram that determines whether E1 is a parent
16303 of E2. For a concurrent type its parent is the first element of its
16304 list of interface types; for other types this function provides the
16305 same result than Is_Ancestor.
16306 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16307 (Collect_Synchronized_Interfaces): Removed because the subprogram
16308 Collect_Abstract_Interfaces provides this functionality.
16309 (Collect_Abstract_Interfaces): Minor update to give support to
16310 concurrent types and thus avoid undesired code duplication.
16311 (Get_Subprogram_Entity): Handle entry calls.
16312 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16314 (Enter_Name): Do not give -gnatwh hiding warning for record component
16315 entities, they never result in hiding.

16322 of the enclosing object.
16323 Add N_Push and N_Pop nodes
16324 New field Exception_Label added
16325 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16326 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

16330 can be an E_Return_Statement.
16331 (Is_Coextension): New flag for allocators.
16332 Remove all code for DSP option

16340 before propagating exception.
16342 2007-04-06 Olivier Hainque <hainque@adacore.com>

16350 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16351 expression with a COMPOUND_EXPR including the call instead of emitting
16352 the call directly here.
16353 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16354 high bound is constant and the slice is empty. Tidy.
16355 (tree_transform, case N_Op_Not): Handle properly the case where the
16356 operation applies to a private type whose full view is a modular type.
16357 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16358 Address_Clause, use the associated Expression as the GNAT tree
16359 representing the choice value to ensure the corresponding GCC tree is
16360 of the proper kind.
16361 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16362 instead of just the operands, as the base GCC stabilize_reference does.
16363 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16364 requested; otherwise fail.
16365 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16370 implementation of UI_Div.
16371 (UI_Div): Reimplement as a call to UI_Div_Rem.
16372 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16373 remainder, avoiding the cost of a multiplication and a subtraction.
16374 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16375 provides both quotient and remainder in a single computation.
16376 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16377 functions for uint.
16378 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

16398 builtin_decls list.
16399 (gnat_install_builtins): Adjust comments.
16400 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

16625 (mainly static expression evaluation).
16626 Reword some continuation messages
16627 Add some \\ sequences to continuation messages
16628 (Resolve_Call): Refine infinite recursion case. The test has been

16642 during analysis, and use May_Be_Lvalue to distinguish read/write.
16643 (Valid_Array_Conversion): New procedure, abstracted from
16644 Valid_Conversion, to incorporate accessibility checks for arrays of
16645 anonymous access types.
16646 (Valid_Conversion): For a conversion to a numeric type occurring in an
16647 instance or inlined body, no need to check that the operand type is
16648 numeric, since this has been checked during analysis of the template.

17237 assignments where the target subtype is unconstrained and the target
17238 object is a parameter or dereference (other aliased cases are known

17443 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17444 return-by-reference has no meaning in Ada 2005.
17445 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17446 to register tag of the immediate ancestor interfaces in the
17447 run-time structure.
17448 (Init_Secondary_Tags): Moved to the specification to allow the
17449 initialization of extension aggregates with abstract interfaces.
17450 (Build_Master_Renaming): Make public, for use by function declarations
17451 whose return type is an anonymous access type.
17452 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17453 Insert_List_Before_And_Analyze after the generation of the specs
17454 associated with null procedures.
17455 (Expand_Tagged_Root): Update documentation in its specification.
17456 (Init_Secondary_Tags): Update documentation.
17457 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17458 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17459 then generate code to inherit the contents of the dispatch table
17460 directly from the ancestor.
17461 (Expand_Record_Controller): Insert controller component after tags of
17462 implemented interfaces.
17463 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17464 create null procedure overridings when null procedures are inherited
17466 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17467 declarations for overriding null primitives inherited from interfaces.
17468 (Is_Null_Interface_Procedure): New function in
17469 Make_Null_Procedure_Specs.
17470 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17471 immediate ancestor of a tagged type is an abstract interface type we
17472 must generate the specification of the predefined primitives associated
17473 with controlled types (because the dispatch table of the ancestor is
17474 null and hence these entries cannot be inherited). This is required to
17475 elaborate well the dispatch table.

17483 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17485 (Expand_N_In): Do validity checks on range
17486 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17487 (Expand_N_Allocator): For "new T", if the object is constrained by
17488 discriminant defaults, allocate the right amount of memory, rather than
17489 the maximum for type T.
17490 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17491 when the allocator is initialized by a build-in-place call, since the
17492 allocator is already rewritten as a reference to the function result,
17493 and this prevents an unwanted duplication of the function call.
17494 Add with and use of Exp_Ch6.
17495 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17496 is a call to build-in-place function and apply
17497 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17498 untagged designated types).
17499 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17500 optimization if source or target is biased.
17501 (Expand_N_Allocator): Add comments for case of an allocator within a
17502 function that returns an anonymous access type designating tasks.
17503 (Expand_N_Allocator): apply discriminant checks for access
17504 discriminants of anonymous access types (AI-402, AI-416)

17509 Ed Schonberg <schonberg@adacore.com>
17511 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17513 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17514 (Expand_N_Assignment_Statement): Call
17515 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17516 build-in-place function call. Currently, this can happen only for
17517 assignments that come from aggregates.
17518 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17519 in order to alleviate the upward compatibility introduced by AI-318.
17520 (Expand_N_Extended_Return_Statement): Add support for handling the
17521 return object as a build-in-place result.
17522 (Expand_Non_Function_Return): Implement simple return statements nested
17523 within an extended return.
17524 (Enable_New_Return_Processing): Turn on the new processing of return
17526 (Expand_Non_Function_Return): For a return within an extended return,
17527 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17528 (Expand_N_Extended_Return_Statement): Implement AI-318
17529 (Expand_Simple_Function_Return): Ditto.
17530 (Expand_N_If_Statement): Handle new -gnatwt warning
17531 (Expand_N_Case_Statement): Handle new -gnatwt warning
17532 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17533 a protected object.
17534 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17535 validity checking of assignments to elementary record components.
17536 (Expand_N_Return_Statement): return Class Wide types on the secondary
17537 stack independantly of their controlled status since with HIE runtimes,
17538 class wide types are not potentially controlled anymore.
17540 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17543 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17544 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17545 it expects a block, procedure, or task. The return statement will get
17546 turned into a block, and Expand_Cleanup_Actions will happen then.

17550 Bob Duff <duff@adacore.com>
17551 Gary Dismukes <dismukes@adacore.com>
17553 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17555 (Expand_Inlined_Call): Tagged types are by-reference types, and
17556 therefore should be replaced by a renaming declaration in the expanded
17557 body, as is done for limited types.
17558 (Expand_Call): If this is a call to a function with dispatching access
17559 result, propagate tag from context.
17560 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17562 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17563 build-in-place when the right-hand side of an assignment is a
17564 build-in-place function call.
17565 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17566 of the explicit dereference of the allocator to the result subtype of
17567 the build-in-place function. This is needed to satisfy type checking
17568 in cases where the caller's return object is created by an allocator for
17569 a class-wide access type and the type named in the allocator is a
17571 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17572 conversion of the reference to the declared object to the result subtype
17573 of the build-in-place function. This is needed to satisfy type checking
17574 in cases where the declared object has a class-wide type. Also, in the
17575 class-wide case, change the type of the object entity to the specific
17576 result subtype of the function, to avoid passing a class-wide object
17577 without explicit initialization to the back end.
17578 (Register_Interface_DT_Entry): Moved outside the body of
17579 Freeze_Subprogram because this routine is now public; it is called from
17580 Check_Dispatching_Overriding to handle late overriding of abstract
17581 interface primitives.
17582 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17583 adding an implicit access actual on a call to a build-in-place function.
17584 (Expand_Actuals): Test for an actual parameter that is a call to a
17585 build-in-place function and apply
17586 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17587 (Is_Build_In_Place_Function): New function to determine whether an
17588 entity is a function whose calls should be handled as build-in-place.
17589 (Is_Build_In_Place_Function_Call): New function to determine whether an
17590 expression is a function call that should handled as build-in-place.
17591 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17592 calls to build-in-place functions as the initialization of an allocator.
17593 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17594 handling calls to build-in-place functions in contexts that do not
17595 involve init of a separate object (for example, actuals of subprogram
17597 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17598 handling calls to build-in-place functions as the initialization of an
17599 object declaration.
17600 (Detect_Infinite_Recursion): Add explicit parameter Process to
17601 instantiation of Traverse_Body to avoid unreferenced warning.
17602 (Check_Overriding_Inherited_Interfaces): Removed.
17603 (Register_Interface_DT_Entry): Code cleanup.
17604 (Register_Predefined_DT_Entry): Code cleanup.
17605 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17606 inlined statements if within a transient scope.
17607 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17608 formal parameters with occurrences of actuals in inlined body, establish
17609 visibility on the proper view of the actual's subtype for the body's
17611 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17612 compatibility mode and we have an imported CPP subprogram because
17613 for now we assume that imported CPP primitives correspond with
17614 objects whose constructor is in the CPP side (and therefore we
17615 don't need to generate code to register them in the dispatch table).
17616 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17617 aligned selected component.
17618 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17619 the actual of an in-mode parameter is a type conversion.
17620 (Expand_Actuals): If the call does not come from source and the actual
17621 is potentially misaligned, let gigi handle it rather than rejecting the
17622 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17623 Class Wide types as returning by reference independantly of their
17624 controlled status since with HIE runtimes class wide types are not
17625 potentially controlled anymore.
17627 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17629 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17630 references that are private components of the protected object.
17631 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17632 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17633 instantiation to deal with warnings.

17635 System_Priority as its expected type, in case the expression has not
17638 2006-10-31 Robert Dewar <dewar@adacore.com>
17640 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17641 initialization of Homonym_Len.
17642 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17643 names from fully qualified name. Fixes problem of duplicate
17644 external names differing only in the presence of such a block name.
17646 2006-10-31 Thomas Quinot <quinot@adacore.com>
17647 Pablo Oliveira <oliveira@adacore.com>
17649 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17650 subprogram Ids, even if they are not yet assigned.
17651 (Build_Subprogram_Id): It is now this function that will take care of
17652 calling Assign_Subprogram_Ids if necessary.
17653 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17654 should be done only once they are assigned.
17655 (Build_From_Any_Function, case of tagged types): Add missing call to
17657 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17658 type for an RACW type.
17659 (Add_RACW_Features): When processing an RACW declaration for which the
17660 designated type is already frozen, enforce E.2.2(14) rules immediately.
17661 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17662 special reordering of controlling formals.
17664 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17665 associated stub type for an RACW type.
17667 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17669 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17670 fixed-point operations in an integer context, i.e. as operands of a
17671 conversion to an integer type, indicate that result must be rounded.
17673 2006-10-31 Robert Dewar <dewar@adacore.com>
17675 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17676 cases, pass the encoding method, since it is now required by the run
17679 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17680 assumption that Str'First = 1.
17681 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17682 it on to the Value_Wide_Wide_Character call.
17683 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17684 properly handles a string of the form quote-encoded_wide_char-quote.
17686 * s-wchcnv.adb: Minor reformatting
17688 2006-10-31 Javier Miranda <miranda@adacore.com>
17690 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17691 run-time membership test to ensure that the constructed object
17692 implements the target abstract interface.
17694 2006-10-31 Robert Dewar <dewar@adacore.com>
17696 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17697 Machine_Attribute pragma internally to implement the user pragma.
17698 Add processing for pragma Interface so that it is now completely
17699 equivalent to pragma Import.
17701 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17702 so that it can be applied to all entities, including record components
17703 and enumeration literals.
17704 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17705 priority ranges are correct, verify compatibility against task
17706 dispatching and locking policies, and if everything is correct an entry
17707 is added to the table containing priority specific dispatching entries
17708 for this compilation unit.
17709 (Delay_Config_Pragma_Analyze): Delay processing
17710 Priority_Specific_Dispatching pragmas because when processing the
17711 pragma we need to access run-time data, such as the range of
17712 System.Any_Priority.
17713 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17714 Allow pragma Unreferenced as a context item
17715 Add pragma Preelaborable_Initialization
17716 (Analyze_Pragma, case Interface): Interface is extended so that it is
17717 now syntactically and semantically equivalent to Import.
17718 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17719 insertion characters.
17720 Add handling for Pragma_Wide_Character_Encoding
17721 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17722 never supercedes a real restriction, and that a real restriction
17723 always supercedes a warning.
17724 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17731 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17732 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17733 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17735 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17736 type of the function containing a return statement, because the
17737 Return_Type field was removed. We now use the Return_Applies_To field.
17739 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17740 (Build_Task_Image_Decl): If procedure is not called from an
17741 initialization procedure, indicate that function that builds task name
17742 uses the sec. stack. Otherwise the enclosing initialization procedure
17743 will carry the indication.
17744 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17745 N_Object_Declaration instead.
17746 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17747 conditional dead code killed, and change implementation accordingly.
17748 (Insert_Actions): Add N_Return_Object_Declaration case.
17749 Correct comment to mention N_Extension_Aggregate node.
17750 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17751 attempts to save information for global variables which cannot be
17753 (Get_Current_Value_Condition): Handle conditions the other way round
17754 (constant on left). Also handle right operand of AND and AND THEN
17755 (Set_Current_Value_Condition): Corresponding changes
17756 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17757 (Get_Current_Value_Condition): Handle simple boolean operands
17758 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17759 (Get_Current_Value_Condition): If the variable reference is within an
17760 if-statement, does not appear in the list of then_statments, and does
17761 not come from source, treat it as being at unknown location.
17762 (Get_Current_Value_Condition): Enhance to allow while statements to be
17763 processed as well as if statements.
17764 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17766 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17767 of loop. This is safe now that we fixed Kill_Current_Values.
17768 (OK_To_Do_Constant_Replacement): Check whether current scope is
17769 Standard, before examining outer scopes.
17771 2006-10-31 Vincent Celier <celier@adacore.com>
17773 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17774 When True, apply VMS treatment to children of packages A, G, I and S.
17777 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17779 2006-10-31 Robert Dewar <dewar@adacore.com>
17780 Ed Schonberg <schonberg@adacore.com>

17783 (Warn_Overlay): Supply missing continuation marks in error msgs
17784 (Freeze_Entity): Add check for Preelaborable_Initialization
17786 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17788 * g-expect.adb: Add Warnings (Off) to prevent new warning
17790 * lib-xref.adb: Add handling of Last_Assignment field
17791 (Generate_Reference): Centralize handling of pragma Obsolescent here
17792 (Generate_Reference): Accept an implicit reference generated for a
17793 default in an instance.
17794 (Generate_Reference): Accept a reference for a node that is not in the
17795 main unit, if it is the generic body corresponding to an subprogram
17798 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17800 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17802 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17804 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17805 use clauses, to avoid messages on packages used to qualify, and also
17806 to avoid messages from obsolescent units.
17807 (Warn_On_Useless_Assignments): Don't generate messages for imported
17808 and exported variables.
17809 (Warn_On_Useless_Assignments): New procedure
17810 (Output_Obsolescent_Entity_Warnings): New procedure
17811 (Check_Code_Statement): New procedure
17813 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
17814 Change name Is_Ada_2005 to Is_Ada_2005_Only
17815 (Last_Assignment): New field for useless assignment warning
17817 2006-10-31 Olivier Hainque <hainque@adacore.com>
17819 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17820 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17822 2006-10-31 Bob Duff <duff@adacore.com>
17823 Robert Dewar <dewar@adacore.com>
17824 Ed Schonberg <schonberg@adacore.com>
17826 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17827 Ada 95 mode, because it violates the new rules for AI-318.
17829 * g-awk.ads: Use overloaded subprograms in every case where we used to
17830 have a default of Current_Session. This makes the code closer to be
17831 correct for both Ada 95 and 2005.
17833 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17834 code, relying on the fact that the compiler generates a warning
17835 instead of an error in -gnatg mode.
17837 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17838 E_Return_Statement entity kind.
17839 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17841 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17842 report an error if the reserved word abstract has been previously found.
17843 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17845 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17846 parenthesized range attribute usage
17847 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17849 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17850 in the syntax for extended_return_statement. This is not in the latest
17851 RM, but the ARG is expected to issue an AI allowing this.
17852 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17853 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17854 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17855 P_Return_Statement): Parse the new syntax for extended_return_statement.
17857 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17858 Output_End_Missing): Add error-recovery code for the new
17859 extended_return_statement syntax; that is, the new E_Return entry on
17862 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17863 limited to nonlimited, because otherwise we violate the new Ada 2005
17864 rules about returning limited types in function Create_AST_Handler in
17867 * sem.adb (Analyze): Add cases for new node kinds
17868 N_Extended_Return_Statement and N_Return_Object_Declaration.
17870 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17871 type is in the same category as type of context before applying check,
17872 to prevent anomalies in instantiations.
17873 (Resolve_Aggregate): Remove test for limited components in aggregates.
17874 It's unnecessary in Ada 95, because if it has limited components, then
17875 it must be limited. It's wrong in Ada 2005, because limited aggregates
17877 (Resolve_Record_Aggregate): Move check for limited types later, because
17878 OK_For_Limited_Init requires its argument to have been resolved.
17879 (Get_Value): When copying the component default expression for a
17880 defaulted association in an aggregate, use the sloc of the aggregate
17881 and not that of the original expression, to prevent spurious
17882 elaboration errors, when the expression includes function calls.
17883 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17884 were missing. We also didn't handle qualified expressions. Now also
17885 allow function calls. Use new common routine OK_For_Limited_Init.
17886 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17887 with space can upper case letter).
17889 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17890 Has_Static_Discriminants flag
17891 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17892 type with discriminants.

17894 (Build_Discriminant_Constraints): Use updated form of
17895 Denotes_Discriminant.
17896 (Process_Subtype): If the subtype is a private subtype whose full view
17897 is a concurrent subtype, introduce an itype reference to prevent scope
17899 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17900 Record_Type_Declaration): The functionality of the subprograms
17901 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17902 is now performed by a single routine.
17903 (Build_Derived_Record_Type): If the type definition includes an explicit
17904 indication of limitedness, then the type must be marked as limited here
17905 to ensure that any access discriminants will not be treated as having
17906 a local anonymous access type.
17907 (Check_Abstract_Overriding): Issue a detailed error message when an
17908 abstract subprogram was not overridden due to incorrect mode of its
17910 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17911 synchronized private extension declarations. Verify that the ancestor is
17912 a limited or synchronized interface or in the generic case, the ancestor
17913 is a tagged limited type or synchronized interface and all progenitors
17914 are either limited or synchronized interfaces.
17915 Derived_Type_Declaration): Check for presence of private extension when
17916 dealing with synchronized formal derived types.
17917 Process_Full_View): Enchance the check done on the usage of "limited" by
17918 testing whether the private view is synchronized.
17919 Verify that a synchronized private view is completed by a protected or
17921 (OK_For_Limited_Init_In_05): New function.
17922 (Analyze_Object_Declaration): Move check for limited types later,
17923 because OK_For_Limited_Init requires its argument to have been resolved.
17924 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17925 in order to alleviate the upward compatibility introduced by AI-318.
17926 (Constrain_Corresponding_Record): If the constraint is for a component
17927 subtype, mark the itype as frozen, to avoid out-of-scope references to
17928 discriminants in the back-end.
17929 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17930 this subprogram against wrong sources.
17931 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17932 discriminant of limited type completed with a protected type, when the
17933 discriminant is used to constrain a private component of the type, and
17934 expansion is disabled.
17935 (Find_Type_Of_Object): Do not treat a return subtype that is an
17936 anonymous subtype as a local_anonymous_type, because its accessibility
17937 level is the return type of the enclosing function.
17938 (Check_Initialization): In -gnatg mode, turn the error "cannot
17939 initialize entities of limited type" into a warning.
17940 (OK_For_Limited_Init): Return true for generated nodes, since it
17941 sometimes violates the legality rules.
17942 (Make_Incomplete_Declaration): If the type for which an incomplete
17943 declaration is created happens to be the currently visible entity,
17944 preserve the homonym chain when removing it from visibility.
17945 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17946 inherited subprograms.
17947 (Access_Definition): If this is an access to function that is the return
17948 type of an access_to_function definition, context is a type declaration
17949 and the scope of the anonymous type is the current one.
17950 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17951 incomplete subtype to the set of private dependents of the original
17953 (Constrain_Discriminated_Type): Emit an error message whenever an
17954 incomplete subtype is being constrained.
17955 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17956 corresponding subtype of the full view of the original incomplete type.
17957 (Check_Incomplete): Properly detect invalid usage of incomplete types

17993 2006-10-31 Vincent Celier <celier@adacore.com>
17995 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17996 call it with -static-libgcc, as there are some platforms, such as
17997 Darwin, where one of these two switches is compulsory to link.
17999 2006-10-31 Vincent Celier <celier@adacore.com>
18001 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18002 instead of ADA_PROJECT_PATH, for the project path.
18003 (Gnatls): When displaying the project path directories, use host dir
18006 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18007 names in the project path, as absolute paths may correspond to
18008 multi-valued VMS logical names.

18025 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18027 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and

18041 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18043 (Layout_Variant_Record): Retrieve the discriminants from the entity
18044 rather than from the type definition, because in the case of a full
18045 type for a private type we need to take the discriminants from the
18047 (Layout_Component_List): When applying the Max operator to variants with
18048 a nonstatic size, check whether either operand is static and scale that
18049 operand from bits to storage units before applying Max.
18050 (Layout_Type): In VMS, if a C-convention access type has no explicit
18051 size clause (and does not inherit one in the case of a derived type),
18052 then the size is reset to 32 from 64.
18054 2006-10-31 Vincent Celier <celier@adacore.com>
18056 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18057 its file has already been loaded, according to the unit being loaded,
18058 not to the current value of Multiple_Unit_Index.
18060 2006-10-31 Thomas Quinot <quinot@adacore.com>
18061 Eric Botcazou <ebotcazou@adacore.com>

18096 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18098 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18099 Process_Body_Clauses): If the context of a body includes a use clause
18100 for P.Q then a with_clause for P in the same body is not redundant,
18101 even if the spec also has a with_clause on P.
18102 Add missing continuation mark to error msg
18103 (Build_Limited_Views): A limited view of a type is tagged if its
18104 declaration includes a record extension.
18105 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18106 node, even if the subunit has errors. This avoids malfunction by
18107 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18108 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18109 generation of obsolescent messages for with statements (cannot do
18110 this too early, or we cannot implement avoiding the messages in the
18111 case of obsolescent units withing obsolescent units).
18112 (Install_Siblings): If the with_clause is on a remote descendant of
18113 an ancestor of the current compilation unit, find whether there is
18114 a sibling child unit that is immediately visible.
18115 (Remove_Private_With_Clauses): New procedure, invoked after completing
18116 the analysis of the private part of a nested package, to remove from
18117 visibility the private with_clauses of the enclosing package
18119 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18120 now centralized in Generate_Reference.
18121 (Install_Limited_Context_Clauses): Remove superfluous error
18122 message associated with unlimited view visible through use
18123 and renamings. In addition, at the point in which the error
18124 is reported, we add the backslash to the text of the error
18125 to ensure that it is reported as a single error message.
18126 Use new // insertion for some continuation messages
18127 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18128 to create implicit with_clause for parent unit mentioned in original
18129 limited_with_clause.
18130 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18131 unit is a child unit. For ASIS queries.

18148 a formal object declaration with an access definition or a subtype mark
18149 with a null exclusion.
18150 (P_Generic_Association): Handle association with box, and others_choice
18151 with box, to support Ada 2005 partially parametrized formal packages.
18153 2006-10-31 Robert Dewar <dewar@adacore.com>
18154 Javier Miranda <miranda@adacore.com>
18156 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18157 (P_Type_Declaration): Remove barrier against the reserved word "limited"

18160 private extensions.
18161 (P_Type_Declaration): Add the new actual Abstract_Present to every call

18189 2006-10-31 Vincent Celier <celier@adacore.com>
18191 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18192 on VMS, change "__" to '.' before checking the name.

18196 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18197 dot, instead of replacing only the first '_'.
18199 * prj-part.adb (Parse): Convert project file path to canonical form
18201 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18202 extended, the project id of the project extending it is recorded in its
18203 data, even when it has already been processed as an imported project.

18211 Robert Dewar <dewar@adacore.com>
18213 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18214 only a restriction warning is active for the given restriction. This is
18215 desirable because we do not want to modify code in the case where only
18217 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18218 causes overriding of real restrictions.
18219 Take advantage of new No_Restrictions constant.
18221 * raise.h: (__gnat_set_globals): Change profile.
18223 2006-10-31 Arnaud Charlet <charlet@adacore.com>

18250 (OK_Self_Reference): New subprogram to check the legality of an access
18251 attribute whose prefix is the type of an enclosing aggregate.
18252 Generalizes previous mechanism to handle attribute references nested
18253 arbitrarily deep within the aggregate.
18254 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18255 can appear in an aggregate if this is a default-initialized aggregate
18256 for a self-referential type.
18257 (Resolve_Attribute, case Access): Ditto.
18258 Add support for new implementation defined attribute Stub_Type.

18270 a class-wide interface to a tagged type.
18271 Add support for the attribute Priority.
18272 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18273 whether the designated type is discriminated with a constrained partial
18274 view and require static matching in that case.
18275 Add local variable Des_Btyp. The Designated_Type
18276 of an access to incomplete subtype is either its non-limited view if
18277 coming from a limited with or its etype if regular incomplete subtype.
18279 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18280 Fix predicate to identify and allow cases of (expander-generated)
18281 references to tag of designated object of a RACW.
18282 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18283 non-static, and therefore cannot appear as a primary in a preelaborable

18286 Has_Read_Write_Attributes.
18287 (Has_Read_Write_Attributes): Reimplement in termes of
18288 Has_Stream_Attribute_Definition.

18293 2006-10-31 Robert Dewar <dewar@adacore.com>
18295 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18296 useless assignments here and conditionalize it on absence of exception
18298 (Analyze_Exception_Handlers): Small code reorganization of error
18299 detection code, for new handling of formal packages.

18309 synchronized. Carry synchronized present over to the generated private
18311 (Validate_Derived_Type_Instance): Ensure that the actual of a
18312 synchronized formal derived type is a synchronized tagged type.
18313 (Instantiate_Formal_Package): When creating the instantiation used to
18314 validate the actual package of a formal declared without a box, check
18315 whether the formal itself depends on a prior actual.
18316 (Instantiate_Formal_Subprogram): Create new entities for the defining
18317 identifiers of the formals in the renaming declaration, for ASIS use.
18318 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18319 a renaming declaration or a subtype declaration for an actual in an
18320 instance, capture location information of declaration in generic, for
18322 (Instantiate_Formal_Package): Add comments on needed additional tests.
18323 AI-317 (partial parametrization) is fully implemented.
18324 (Validate_Private_Type_Instance): Add check for actual which
18325 must have preelaborable initialization
18326 Use new // insertion for some continuation messages
18327 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18328 Default_Expression. Add type retrieval when the declaration has an
18329 access definition. Update premature usage of incomplete type check.
18330 (Check_Access_Definition): New subsidiary routine. Check whether the
18331 current compilation version is Ada 05 and the supplied node has an
18333 (Instantiate object): Alphabetize local variables. Handle the creation
18334 of new renaming declarations with respect to the kind of definition
18335 used - either an access definition or a subtype mark. Guard against
18336 unnecessary error message in the context of anonymous access types after
18337 they have been resolved. Add check for required null exclusion in a
18338 formal object declaration.
18339 (Switch_View): A private subtype of a non-private type needs to be
18340 switched (the base type can have been switched without its private
18341 dependents because of the last branch of Check_Private_View.
18342 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18344 (Instantiate_Type): Emit an error message whenever a class-wide type of
18345 a tagged incomplete type is used as a generic actual.
18346 (Find_Actual_Type): Extend routine to handle a component type in a child
18347 unit that is imported from a formal package in a parent.
18348 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18349 agree on constrainedness, rather than checking against ultimate ancestor
18350 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18351 generic body, for navigation purposes.
18353 2006-10-31 Robert Dewar <dewar@adacore.com>
18354 Thomas Quinot <quinot@adacore.com>
18356 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18358 (New_Stream_Subprogram): When processing an attribute definition clause
18359 for a stream-oriented subprogram, record an entity node occurring at
18360 the point of clause to use for checking the visibility of the clause,
18361 as defined by 8.3(23) as amended by AI-195.
18362 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18363 New_Stream_Function and New_Stream_Procedure.
18364 (New_Stream_Function, New_Stream_Procedure): Removed.
18365 (Analyze_Attribute_Definition_Clause, case Address): Check new
18366 Alignment_Check check

18369 Javier Miranda <miranda@adacore.com>
18370 Robert Dewar <dewar@adacore.com>
18372 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18373 generate the same errors compiling under -gnatc.
18374 (Try_Object_Operation): If no candidate interpretation succeeds, but
18375 there is at least one primitive operation with the right name, report
18376 error in call rather than on a malformed selected component.
18377 (Analyze_Selected_Component): If the prefix is an incomplete type from
18378 a limited view, and the full view is available, use the full view to
18379 determine whether this is a prefixed call to a primitive operation.
18380 (Operator_Check): Verify that a candidate interpretation is a binary
18381 operation before checking the type of its second formal.
18382 (Analyze_Call): Add additional warnings for function call contexts not
18384 (Analyze_Allocator): Move the check for "initialization not allowed for
18385 limited types" after analyzing the expression. This is necessary,
18386 because OK_For_Limited_Init looks at the structure of the expression.
18387 Before analysis, we don't necessarily know what sort of expression it
18388 is. For example, we don't know whether F(X) is a function call or an
18389 indexed component; the former is legal in Ada 2005; the latter is not.
18390 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18391 were missing. We also didn't handle qualified expressions. Now also
18392 allow function calls. Use new common routine OK_For_Limited_Init.
18393 (Analyze_Type_Conversion): Do not perform some legality checks in an
18394 instance, because the error message will be redundant or spurious.
18395 (Analyze_Overloaded_Selected_Component): Do not do style check when
18396 setting an entity, since we do not know it is the right entity yet.
18397 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18398 (Analyze_Overloaded_Selected_Component): Same change
18399 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18400 since regular incomplete subtypes are transformed into corresponding
18401 subtypes of their full views.
18402 (Complete_Object_Operation): Treat name of transformed subprogram call
18403 as coming from source, for browsing purposes.
18404 (Try_Primitive_Operation): If formal is an access parameter, compare
18405 with base type of object to determine whether it is a primitive
18407 (Operator_Check): If no interpretation of the operator matches, check
18408 whether a use clause on any candidate might make the operation legal.
18409 (Try_Class_Wide_Operation): Check whether the first parameter is an
18410 access type whose designated type is class-wide.
18412 2006-10-31 Robert Dewar <dewar@adacore.com>
18413 Ed Schonberg <schonberg@adacore.com>
18414 Gary Dismukes <dismukes@adacore.com>
18416 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18417 warn on infinite loops.
18418 Add \\ to some continuation messages
18419 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18420 (Process_Bounds): If the bounds are integer literals that result from
18421 constant-folding, and they carry a user-defined type, preserve that type
18422 rather than treating this as an integer range.
18423 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18424 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18425 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18426 left hand side of assignment.
18427 (Analyze_Assignment): Add suport to manage assigments to the attribute
18428 priority of a protected object.
18429 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18430 not just identifiers.
18431 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18432 or AND THEN for possible tracking.
18433 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18434 case of while loops so we can track values in the loop body.
18436 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18437 Hristian Kirtchev <kirtchev@adacore.com>
18438 Bob Duff <duff@adacore.com>
18440 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18441 procedure cannot be a protected operation (it is a basic_declaration,
18442 not a subprogram_declaration).
18443 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18444 Subp. Add logic for entry processing.
18445 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18446 Determine whether an entry or subprogram of a protected or task type
18447 override an inherited primitive of an implemented interface.
18448 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18449 Update the actual used in calls to Check_Overriding_Indicator.
18450 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18451 generate the proper reference to the parent unit, for cross-reference.
18452 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18454 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18455 (Add_Extra_Formal): Revise procedure to allow passing in associated
18456 entity, scope, and name suffix, and handle setting of the new
18457 Extra_Formals field.
18458 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18459 pass new parameters. Add support for adding the new extra access formal
18460 for functions whose calls are treated as build-in-place.
18461 (Analyze_A_Return_Statement): Correct casing in error message.
18462 Move Pop_Scope to after Analyze_Function_Return, because an extended
18463 return statement really is a full-fledged scope. Otherwise, visibility
18464 doesn't work right. Correct use of "\" for continuation messages.
18465 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18466 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18467 the node doesn't get properly marked as analyzed.
18468 (Analyze_Subprogram_Body): If subprogram is a function that returns
18469 an anonymous access type that denotes a task, build a Master Entity
18471 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18472 proper usage of null exclusion in a result definition.
18473 (Process_Formals): Code cleanup and new error message.
18474 (Process_Formals): Detect incorrect application of null exclusion to
18476 (Conforming_Types): Handle conformance between [sub]types and itypes
18477 generated for entities that have null exclusions applied to them.
18478 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18479 base type is an access subtype. This case arrises with null exclusions.
18480 (New_Overloaded_Entity): Do not remove the overriden entity from the
18481 homonym chain if it corresponds with an abstract interface primitive.
18482 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18483 call to the synthesized predicate Is_Incomplete_Type.
18484 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18486 (Analyze_Subprogram_Declaration): Check that abstract interface
18487 primitives are abstract or null.
18488 (Analyze_Subprogram_Specification): Remove previous check for abstract
18489 interfaces because it was not complete.
18490 (Has_Interface_Formals): Removed.
18492 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18493 Javier Miranda <miranda@adacore.com>
18495 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18496 of Analyze_Package_Body, to create Itype references for anonymous
18497 access types created in the package declaration, whose designated types
18498 may have only a limited view.
18499 (Analyze_Package_Specification): For the private part of a nested
18500 package, install private_with_clauses of enclosing compilation unit if
18501 we are in its visible part.
18502 (Declare_Inherited_Private_Subprograms): Complete barrier
18503 to ensure that the primitive operation has an alias to some parent
18504 primitive. This is now required because, after the changes done for the
18505 implementation of abstract interfaces, the contents of the list of
18506 primitives has entities whose alias attribute references entities of
18507 such list of primitives.
18508 (Analyze_Package_Specification): Simplify code that handles parent units
18509 of instances and formal packages.
18510 (Uninstall_Declarations): Check the convention consistency among
18511 primitive overriding operations of a tagged record type.
18513 2006-10-31 Robert Dewar <dewar@adacore.com>

18515 Javier Miranda <miranda@adacore.com>
18516 Ed Schonberg <schonberg@adacore.com>
18518 * sem_ch8.adb: Minor error msg rewording
18519 (Undefined): When checking for misspellings, invert arguments (to get
18520 expected and found set right)
18521 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18522 (Analyze_Generic_Renaming): Same fix
18523 (Use_One_Package): Do not take into account the internal entities of
18524 abstract interfaces during the analysis of entities that are marked
18525 as potentially use-visible.
18526 (Find_Type): Handle the case of an attribute reference for
18527 implementation defined attribute Stub_Type (simply let the analysis of
18528 the attribute reference rewrite it).
18529 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18530 type that appears in a Use_Type clause.
18531 (Analyze_Object_Renaming): Add support for renaming of the Priority
18533 (Find_Type): In Ada 2005, a task type can be used within its own body,
18534 when it appears in an access definition.
18535 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18536 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18537 in a formal object declaration or in a subtype declaration.
18538 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18539 (Check_Null_Exclusion): New local routine to
18540 Analyze_Subprogram_Renaming. Check whether the formals and return
18541 profile of a renamed subprogram have required null exclusions when
18542 their counterparts of the renaming already impose them.
18543 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18544 Determine whether an entity is inside a generic scope.
18545 (In_Open_Scope): First pass of documentation update.
18546 (Find_Expanded_Name): Add support for shadow entities associated with
18547 limited withed packages. This is required to handle nested packages.
18548 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18549 that makes a renaming of a limited withed package illegal.
18551 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18552 Ed Schonberg <schonberg@adacore.com>
18554 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18555 Check_Overriding_Indicator.
18556 (Analyze_Task_Definition): Ditto.
18557 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18558 (Check_Overriding_Indicator): To find overridden interface operation,
18559 examine only homonyms that have an explicit subprogram declaration, not
18560 inherited operations created by an unrelated type derivation.
18561 (Check_Overriding_Indicator): When checking for the presence of "null"
18562 in a procedure, ensure that the queried node is a procedure
18564 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18565 type when the formal is an access to variable.
18566 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18567 (Analyze_Task_Type): Same addition
18568 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18569 provide navigation capabilities for entries.

18574 Gary Dismukes <dismukes@adacore.com>
18576 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18577 inherited from an interface ancestor by another interface in the
18578 context of an instance as 'late'.
18579 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18580 of a call to a function that dispatches on access result.
18581 (Check_Dispatching_Operation): In case of late overriding of a primitive
18582 that covers abstract interface subprograms we register it in all the
18583 secondary dispatch tables associated with abstract interfaces.
18584 (Check_Dispatching_Call): Add check that a dispatching call is not made
18585 to a function with a controlling result of a limited type. This is a
18586 current implementation restriction.
18587 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18588 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18589 argument is an interface type that is a generic formal.
18590 (Is_Interface_Subprogram): Removed.
18591 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18592 operation, check the formals to handle the case in which it is
18593 associated with an abstract interface type.
18595 2006-10-31 Robert Dewar <dewar@adacore.com>
18596 Ed Schonberg <schonberg@adacore.com>

18606 Current_Value in the conditional case, to evaluate additional
18607 comparisons at compile time.

18610 Hristian Kirtchev <kirtchev@adacore.com>
18611 Javier Miranda <miranda@adacore.com>
18613 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18614 subprogram type to provide better diagnostics in case of ambiguity.
18615 (Covers): Handle coverage of formal and actual anonymous access types in
18616 the context of generic instantiation.
18617 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18618 abstract interface types; this is required to handle concurrent types
18619 with discriminants and abstract interface types.
18620 (Covers): Include type coverage of both regular incomplete subtypes and
18621 incomplete subtypes of incomplete type visibles through a limited with

18633 Add missing continuation marks in error msgs
18634 (Unqualify): New function for removing zero or more levels of
18635 qualification from an expression. There are numerous places where this
18636 ought to be used, but we currently only deal properly with zero or one
18638 (In_Instance); The analysis of the actuals in the instantiation of a
18639 child unit is not within an instantiation, even though the parent
18640 instance is on the scope stack.
18641 (Safe_To_Capture_Value): Exclude the case of variables that are
18643 (Check_Obsolescent): Removed
18644 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
18645 is an aliased view, even when rewritten as a reference to the target
18646 object in an assignment.
18647 (Get_Subprogram_Entity): New function
18648 (Known_To_Be_Assigned): New function
18649 (Type_Access_Level): Compute properly the access level of a return

18656 has a null exclusion depending on its Nkind.
18657 Change Is_Lvalue to May_Be_Lvalue
18658 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18659 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18660 (Safe_To_Capture_Value): Extend functionality so it can be used for
18661 the current value condition case.
18662 (Has_Compatible_Alignment): New function
18663 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18664 objects to handle the Ada 2005 case, where aliasedness no longer implies
18665 that the object is constrained. In particular, for dereferenced names,
18666 the designated object must be assumed to be unconstrained.
18667 (Kill_Current_Values): Properly deal with the case where we encounter
18668 a loop in the scope chain.
18669 (Safe_To_Capture_Value): Do not let a loop stop us from capturing

18679 * s-osinte-tru64.adb:
18680 Mark Asm statements Volatile to prevent warnings (seems a
18681 reasonable change anyway)
18684 * s-mastop-irix.adb: Add Volatile to Asm statements
18685 Suppresses warning, and seems appropriate in any case
18687 * s-osinte-vms.adb: Add Volatile to Asm statement

18703 (Has_Self_Reference): New flag on aggregates, to indicate that they
18704 contain a reference to the enclosing type, inserted through a default
18706 (Next_Rep_Item): Move from Node4 to Node5.
18707 (Entity): Add this field for N_Attribute_Definition_Clause.
18708 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
18709 (N_Return_Object_Declaration): Remove this node kind. We now use

18712 N_Extended_Return_Statement.
18713 (Procedure_To_Call): Move to a different place to make room in
18714 N_Extended_Return_Statement.
18715 (Return_Type): Removed this field to make room in return statements
18717 (Return_Statement_Entity): New field in return statements, in part to
18718 replace Return_Type, and in part to support the fact that return
18719 statements are now pushed on the scope stack during semantic analysis.
18720 (Return_Object_Declarations): New field to support extended return
18722 (N_Extended_Return_Statement): New node for extended_return_statement
18724 (N_Return_Object_Declaration): New node for part of
18725 extended_return_statement nonterminal. Needed because all the necessary
18726 fields won't fit in N_Extended_Return_Statement.
18727 Generic_associations now carry the Box_Present flag, to indicate a
18728 default for an actual in a partially parametrized formal package.
18730 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
18731 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
18732 and for the new predefined dispatching policies: EDF_Across_Priorities,

18746 print null exclusion twice in the case of an access definition,
18747 Implement new -gnatL switch
18748 Remove N_Return_Object_Declaration. We now use
18749 N_Object_Declaration instead. Implement the case for
18750 N_Extended_Return_Statement. Alphabetize the cases.
18751 Add cases for new nodes N_Extended_Return_Statement and
18752 N_Return_Object_Declaration. The code is not yet written.
18753 Update the output for N_Formal_Object_Declaration
18754 and N_Object_Renaming_Declaration.

18773 * s-scaval.adb (Initialize): Add new Boolean flag AFloat that is set
18774 True when AAMP extended floating-point is in use (48-bit). Change type
18775 ByteLF to ByteLLF, add new array type ByteLF and condition the size of
18776 the two byte array types on AFloat. Change type of IV_Ilf overlay
18777 variable from Byte8 to ByteLF. Add appropriate initializations of
18778 floating-point overlays for AAMP cases.

19357 then we close To if it is valid.
19359 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
19361 * init.c (facility_resignal_table): new array
19362 (__gnat_default_resignal_p): enhance default predicate to resignal if
19363 VMS condition has one of the predefined facility codes.
19365 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
19367 * Makefile.in: Use VMS64 specialized versions of several units in
19368 Interfaces.C hierarchy to be compatible with HP C default size choices.
19369 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
19371 2006-02-17 Ed Schonberg <schonberg@adacore.com>
19373 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
19374 instantiation, the corresponding entity is the related_instance of the
19375 wrapper package created for the instance.
19377 2006-02-17 Ed Schonberg <schonberg@adacore.com>
19379 * sem_ch12.adb (Analyze_Package_Instantiation): Inline_Now is false if
19380 the current instance is nested within another instance in a child unit.

19383 Ed Schonberg <schonberg@adacore.com>
19385 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
19386 type we cannot inherit the primitive operations; we inherit the
19387 Corresponding_Record_Type (which has the list of primitive operations).
19388 (Check_Anonymous_Access_Types): When creating anonymous access types for
19389 access components, use Rewrite in order to preserve the tree structure,
19391 (Analyze_Object_Declaration): For limited types with access
19392 discriminants with defaults initialized by an aggregate, obtain
19393 subtype from aggregate as for other mutable types.
19394 (Derived_Type_Declaration): If the derived type is a limited interface,
19395 set the corresponding flag (Is_Limited_Record is not sufficient).

19401 expression must be the first variable declared in the body of the
19404 2006-02-17 Javier Miranda <miranda@adacore.com>
19406 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19407 abstract interface type, the static analysis is not enough to know if
19408 the interface is implemented or not by the source tagged type. Hence
19409 we must pass the work to the expander to generate the required code to
19410 evaluate the conversion at run-time.
19411 (Resolve_Equality_Op): Do not apply previous
19412 transformation if expansion is disasbled, to prevent anomalies when
19413 locating global references in a generic unit.

19447 this to ["5B"] and the new comments say why not.
19450 Add note for -gnatVo that this now includes the cases of type
19451 conversions and qualified expressions.

19593 table to take advantage of the 16 priority levels available on Windows
19594 2000 and XP. On NT4 there are only 7 priority levels, this is properly
19595 supported by this new mapping.

19641 (Read): Change the implementation to support unicode characters. It is
19642 not possible to use strlen() on Windows as this version supports only
19643 standard ASCII characters. So the length of the directory entry is now
19644 returned from the imported __gnat_readdir routine.
19645 Update copyright notice.

19682 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
19683 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
19684 necessary since these are not different types and pointers may
19685 actually designate any subtype in this hierarchy.
19686 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
19687 discriminants but put them into record only if not Unchecked_Union;
19688 pass flag to components_to_record showing Unchecked_Union.
19689 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
19690 components before variants; don't set TYPE_UNCHECKED_UNION_P.
19691 (components_to_record): New argument UNCHECKED_UNION.
19692 Remove special case code for Unchecked_Union and instead use main code
19693 with small changes.
19696 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
19697 variable with the expression being built, only its inner field.
19699 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Remove call to
19700 emit_sequence_entry_statements.
19701 (emit_sequence_entry_statements, body_with_handlers_p): Delete.

19705 for a subprogram if it has a foreign convention or is exported.
19706 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
19707 substituted for a CONST_DECL.
19708 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
19709 Etype to assoc_to_constructor.
19710 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
19711 discriminants of Unchecked_Union.
19712 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
19713 don't need cluttering preprocessor directives.
19714 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
19715 condition handler as current in the compiled function.
19716 (body_with_handlers_p): New function. Tell whether a given sequence of
19717 statements node is attached to a package or subprogram body and involves
19718 exception handlers possibly nested within inner block statements.
19719 (emit_sequence_entry_statements): New function, to emit special
19720 statements on entry of sequences when necessary. Establish GNAT
19721 condition handler in the proper cases for VMS.
19722 (Handled_Sequence_Of_Statements_to_gnu): Start block code with
19723 emit_sequence_entry_statements.
19725 * utils2.c (find_common_type): If both input types are BLKmode and
19726 have a constant size, use the smaller one.

19750 Add comments that this version is now used only by the compiler and
19751 other basic tools. The full version that includes the Ada 2005 stuff
19752 is in separate files a-except-2005.ads/adb. The reason is that we do
19753 not want to cause bootstrap problems with compilers not recognizing

20222 (Offset_To_Top): The type of the actual has been changed to Address to
20223 give the correct support to tagged types with discriminants. In this
20224 case this value is stored just immediately after the tag field.
20225 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20226 offset_to_top value is static and hence pass this value to the run-time
20227 to store it in the table of interfaces, or else if this value is dynamic
20228 and then pass to the run-time the address of a function that is
20229 generated by the expander to provide this value for each object of the

20244 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20245 in a subprogram are wrapped in a cleanup block, indicate that the
20246 subprogram contains an inner block with an exception handler.
20247 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20248 Adjust call is for a newly-allocated object. In that case we must not
20249 assume that the finalization list chain pointers are correct (since they
20250 come from a bit-for-bit copy of the original object's pointers) so if
20251 the attach level would otherwise be zero (no change), we set it to 4
20252 instead to cause the pointers to be reset to null.
20254 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20255 reset chain pointers to null.
20257 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20259 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20260 string, and the context requires a loop for the assignment (e.g.
20261 because the left-hand side is packed), generate a unique name for the
20262 temporary that holds the string, to prevent spurious name clashes.
20264 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20265 Javier Miranda <miranda@adacore.com>
20266 Robert Dewar <dewar@adacore.com>
20267 Gary Dismukes <dismukes@adacore.com>
20269 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20270 return unconstrained arrays.
20272 (Expand_Call): An indirect call through an access parameter of a
20273 protected operation is not a protected call.
20274 Add circuit to raise CE in Ada 2005 mode following call
20275 to Raise_Exception.
20276 (Register_DT_Entry): Do nothing if
20277 the run-time does not give support to abstract interfaces.
20278 (Freeze_Subprogram): In case of dispatching operations, do not generate
20279 code to register the operation in the dispatch table if the source
20280 is compiled with No_Dispatching_Calls.
20281 (Register_Predefined_DT_Entry): Generate code that calls the new
20282 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20283 Set_Prim_Op_Address.
20285 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20286 on array assignments if the right-hand side is a function call that has
20287 been inlined. Check is performed on the assignment in the block.
20288 (Process_Bounds): If bounds and range are overloaded, apply preference
20289 rule for root operations to disambiguate, and diagnose true ambiguity.
20290 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20291 a tag-indeterminate right-hand side even when Expander_Active is True.
20292 Needed to ensure that dispatching calls to T'Input are allowed and
20293 get the tag of the target class-wide object.
20295 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20296 an inherited primitive operation that already overrides several
20297 abstract interface primitives. For transitivity, the new entity must
20298 also override all the abstract interface primitives covered by the
20299 inherited overriden primitive.
20300 Emit warning if new entity differs from homograph in same scope only in
20301 that one has an access parameter and the other one has a parameter of
20302 a general access type with the same designated type, at the same
20303 position in the signature.
20304 (Make_Inequality_Operator): Use source locations of parameters and
20305 subtype marks from corresponding equality operator when creating the
20306 tree structure for the implicit declaration of "/=". This does not
20307 change anything in behaviour except that the decoration of the
20308 components of the subtree created for "/=" allows ASIS to get the
20309 string images of the corresponding identifiers.
20310 (Analyze_Return_Statement): Remove '!' in warning message.
20311 (Check_Statement_Sequence): Likewise.
20312 (Analyze_Subprogram_Body): For an access parameter whose designated type
20313 is an incomplete type imported through a limited_with clause, use the
20314 type of the corresponding formal in the body.
20315 (Check_Returns): Implicit return in No_Return procedure now raises
20316 Program_Error with a compile time warning, instead of beging illegal.
20317 (Has_Single_Return): Function returning unconstrained type cannot be
20318 inlined if expression in unique return statement is not an identifier.
20319 (Build_Body_To_Inline): It is possible to inline a function call that
20320 returns an unconstrained type if all return statements in the function
20321 return the same local variable. Subsidiary procedure Has_Single_Return
20322 verifies that the body conforms to this restriction.
20324 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20325 same type, and one of them is of an anonymous access type, convert
20326 the other operand to it, so that this is a valid binary operation for
20328 (Resolve_Type_Conversion): Handle subtypes of protected types and
20329 task types when accessing to the corresponding record type.
20330 (Resolve_Allocator): Add '\' in 2-line warning message.
20331 Remove '!' in warning message.
20332 (Resolve_Call): Add '\' in 2-line warning message.
20333 (Valid_Conversion): Likewise.
20334 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20335 resulting type may be an access type with an implicit dereference.
20336 Obtain the proper component from the designated type.
20337 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20338 given by an expanded name with prefix Standard, when the operands are
20339 of an anonymous access type.
20340 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20341 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20342 prefix of the expression is not of an incomplete type. Allows full
20343 diagnoses of all semantic errors.
20344 (Resolve_Actuals): If the actual is an allocator whose directly
20345 designated type is a class-wide interface we build an anonymous
20346 access type to use it as the type of the allocator. Later, when
20347 the subprogram call is expanded, if the interface has a secondary
20348 dispatch table the expander will add a type conversion to force
20349 the displacement of the pointer.
20350 (Resolve_Call): If a function that returns an unconstrained type is
20351 marked Inlined_Always and inlined, the call will be inlined and does
20352 not require the creation of a transient scope.
20353 (Check_Direct_Boolean_Op): Removed
20354 (Resolve_Comparison_Op): Remove call to above
20355 (Resolve_Equality_Op): Remove call to above
20356 (Resolve_Logical_Op): Inline above, since this is only call.
20357 (Valid_Conversion): Handle properly conversions between arrays of
20358 convertible anonymous access types.
20361 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20362 the literal in an unchecked conversion, because GCC 4.x needs a static
20363 value for a string bound.
20365 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20366 Hristian Kirtchev <kirtchev@adacore.com>
20368 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20369 components of the corresponding record, take into account component
20370 definitions that are access definitions.
20371 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20372 procedure is not considered a dispatching call and will be expanded
20375 2006-02-13 Javier Miranda <miranda@adacore.com>
20377 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20378 controlling argument of the dispatching call is an abstract interface
20379 class-wide type then we use it directly.
20380 Check No_Dispatching_Calls restriction.
20381 (Default_Prim_Op_Position): Remove the code that looks for the last
20382 entity in the list of aliased subprograms. This code was wrong in
20384 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20385 when the source is compiled with the No_Dispatching_Calls restriction.
20386 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20387 if we are compiling with restriction No_Dispatching_Calls.
20388 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20389 subprograms if we are compiling under No_Dispatching_Calls restriction.
20390 (Make_DT): Generate a dispatch table with a single dummy entry if
20391 we are compiling with the No_Dispatching_Calls restriction. In
20392 addition, in this case we don't generate code that calls to the
20393 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20394 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20395 of this subprogram if compiling with the No_Dispatching_Calls
20397 (Expand_Type_Conversion): Instead of using the actual parameter,
20398 the argument passed as parameter to the conversion function was
20399 erroneously referenced by the expander.
20400 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20401 Set_Predefined_Primitive_Op_Address and Set_Signature.
20402 (Expand_Dispatching_Call): Generate call to
20403 Get_Predefined_Prim_Op_Address for predefined primitives.
20404 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20405 predefined primitives.
20406 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20407 primitives we reserve one dummy entry to ensure that the tag does not
20408 point to some memory that is associated with some other object. In
20409 addition, remove all the old code that generated the assignments
20410 associated with the signature of the dispatch table and replace them
20411 by a call to the new subprogram Set_Signature.
20412 (Set_All_DT_Position): Change the algorithm because now we have a
20413 separate dispatch table associated with predefined primitive operations.
20414 (Expand_Interface_Conversion): In case of non-static offset_to_top
20415 add explicit dereference to get access to the object after the call
20416 to displace the pointer to the object.
20417 (Expand_Interface_Thunk): Modify the generation of the actual used
20418 in the calls to the run-time function Offset_To_Top to fulfil its
20420 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20422 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20424 * exp_dist.adb (Copy_Specification): For access parameters, copy
20425 Null_Exclusion flag, which will have been set for stream subprograms
20428 2006-02-13 Pascal Obry <obry@adacore.com>
20430 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20431 previous implementation was using the C runtime spawnve routine but
20432 the corresponding wait was using directly the Win32 API. This was
20433 causing some times a lock when waiting for an event using
20434 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20435 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20436 API fixes this problem.
20438 2006-02-13 Robert Dewar <dewar@adacore.com>
20440 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20449 (packed) array reference as analyzed to prevent a forthcoming
20450 reanalysis from resetting its type to the original (non-packed) array
20453 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20454 Javier Miranda <miranda@adacore.com>
20455 Eric Botcazou <ebotcazou@adacore.com>
20457 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20458 Is_Predefined_Primitive_Operation): When
20459 searching for the predefined equality operator, verify that operands
20460 have the same type.
20461 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20462 for the last entity in the list of aliased subprograms. This code
20463 was wrong in case of renamings.
20464 (Set_Renamed_Subprogram): New procedure
20465 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20466 Exp_Type constant computed when entering this subprogram.

20469 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20470 (Side_Effect_Free): An attribute reference 'Input is not free of
20471 side effect, unlike other attributes that are functions. (from code
20473 (Remove_Side_Effects): Expressions that involve packed arrays or records
20474 are copied at the point of reference, and therefore must be marked as
20475 renamings of objects.
20476 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20477 not a dispatching operation.
20480 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20481 elementary types in all cases.

20486 task types when accessing to the corresponding record type.
20487 Remove '!' in warning message.
20489 2006-02-13 Olivier Hainque <hainque@adacore.com>
20491 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20492 to avoid useless and space inefficient overalignments on targets where
20493 Max_Alignment is larger than 16.
20495 2006-02-13 Pascal Obry <obry@adacore.com>
20497 * g-catiio.adb (Sec_Number): New type used to compute the number of
20498 seconds since 1-1-1970.
20499 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20500 negative numbers (years, months...) it is better to have a Natural here.
20502 (Image) [Number]: Change parameter from Long_Integer to Number.
20503 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20504 overflow for dates past year 2038.
20506 2006-02-13 Matthew Heaney <heaney@adacore.com>
20508 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20511 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20513 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20515 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20516 finalization can occur normally.
20518 2006-02-13 Vincent Celier <celier@adacore.com>
20520 * gnatcmd.adb (Rules_Switches): New table
20521 (Add_To_Rules_Switches): New procedure
20522 (GNATCmd): For command CHECK, put all options following "-rules" in the
20523 Rules_Switches table. Append these -rules switches after the -cargs
20526 2006-02-13 Robert Dewar <dewar@adacore.com>
20528 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20529 These two cases were generating incorrect output, and if this unit
20530 was built with checks on, generated a discriminant mismatch constraint
20533 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20534 Robert Dewar <dewar@adacore.com>
20536 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20537 view is an array type, indicate the component type as well, for
20538 navigation purposes.

20540 of violating pragma Unreferenced.
20541 Do not give Ada 2005 warning except on real reference.

20545 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20546 main source, add switch -mdebug-main=_ada_ so that the executable can
20547 be debugged by the standard VMS debugger.
20548 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20549 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20550 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20551 of the last source, as the binding and linking phases are never
20553 Set all executable obsolete when rebuilding a library.
20555 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20558 2006-02-13 Javier Miranda <miranda@adacore.com>
20561 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20562 code to improve the error message reported when the program has
20563 declarations of abstract interface types and it is not compiled with
20564 the -gnat05 switch.
20565 (P_Access_Definition): Reorganize the code to improve the error
20566 message reported when the new Ada 2005 syntax for anonymous
20567 access types is used and the program is not compiled with the

20620 When removing nodes (attributes Source_Dirs, Source_Files,
20621 Source_List_File and package Naming), save the comments and attach the
20622 saved comments to the newly created nodes.

20639 No_Return procedure with procedure that is not No_Return
20640 (Check_Dispatching_Call): Suppress the check for an abstract operation
20641 when the original node of an actual is a tag-indeterminate attribute
20642 call, since the attribute, which must be 'Input, can never be abstract.
20643 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20644 call to the Input attribute (even when rewritten).
20645 (Propagate_Tag): Augment comment to indicate the possibility of a call

20663 handles default-initialized components to keep separate the management
20664 of this feature but also avoid the unrequired resolution and
20665 expansion of components that do not have partially initialized
20667 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20668 (Check_Bounds): Likewise.
20669 (Check_Length): Likewise.

20672 Ed Schonberg <schonberg@adacore.com>
20674 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20675 abstract interface type call analyze_and_resolve to expand the type
20676 conversion into the corresponding displacement of the
20677 reference to the base of the object.
20678 (Eval_Attribute, case Width): For systems where IEEE extended precision
20679 is supported, the maximum exponent occupies 4 decimal digits.
20680 (Accessibility_Message): Add '\' in 2-line warning message.
20681 (Resolve_Attribute): Likewise.
20682 (case Attribute_Access): Significantly revise checks
20683 for illegal access-to-subprogram Access attributes to properly enforce
20684 the rules of 3.10.2(32/2).
20685 Diagnose use of current instance with an illegal attribute.
20687 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal

20690 enclosing generic declaration node.
20691 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20692 (Type_Access_Level): The accessibility level of anonymous acccess types
20693 associated with discriminants is that of the current instance of the
20694 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20695 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20696 (Kill_Current_Values_For_Entity): New function
20697 (Enter_Name): Change formal type to Entity_Id

20700 Ed Schonberg <schonberg@adacore.com>
20701 Gary Dismukes <dismukes@adacore.com>
20703 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20704 Analyze_Compilation_Unit.

20711 unused packages can be properly generated
20712 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20713 has Error_Posted set. Prevent infinite loops in illegal programs.
20714 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20715 to the point of the error test requiring the current unit to be private.
20716 This ensures that private with clauses are not exempted from the basic
20717 checking for being a descendant of the same library unit parent as a
20718 withed private descendant unit.
20719 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20720 handle private with clauses properly, as well as to account for cases
20721 where the withed unit is a public descendant of a private ancestor
20722 (in which case the current unit must be a descendant of the private
20723 ancestor's parent). The spec comments were updated accordingly. Also,
20724 the old error message in this subprogram was replaced with error
20725 messages that mirror the errors tested and reported by
20726 Check_Private_Child_Unit.
20727 Parameter and variable names improved for readability.
20728 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20729 private as the precondition for calling
20730 Check_Private_Limited_Withed_Unit since that subprogram has been
20731 revised to test public units as well as private units.

20736 Javier Miranda <miranda@adacore.com>
20738 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20739 that Scope_Stack.First = 1.
20740 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20741 were not always properly handled previously.
20742 (Formal_Entity): Complete rewrite, to handle properly some complex case
20743 with multiple levels of parametrization by formal packages.
20744 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20745 to the corresponding derived type declaration for proper semantics.
20747 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20748 (Check_Component): Enforce restriction on components of
20749 unchecked_unions: a component in a variant cannot contain tasks or
20751 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20753 Add pragma Ada_2005 (synonym for Ada_05)
20754 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20755 were not always properly handled previously.
20756 Document that pragma Propagate_Exceptions has no effect
20757 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20758 (Set_Convention_From_Pragma): Check that if a convention is
20759 specified for a dispatching operation, then it must be
20760 consistent with the existing convention for the operation.
20761 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20762 longer required to specify an vtable-ptr component in the record. For
20763 compatibility reasons we leave the support for the previous definition.
20764 (Analyze_Pragma, case No_Return): Allow multiple arguments
20766 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20767 non-overrideen inherited operation with a controlling result as
20768 illegal only its implicit declaration comes from the derived type
20769 declaration of its result's type.
20770 (Check_Possible_Deferred_Completion): Relocate the object definition
20771 node of the subtype indication of a deferred constant completion rather
20772 than directly analyzing it. The analysis of the generated subtype will
20773 correctly decorate the GNAT tree.
20774 (Record_Type_Declaration): Check whether this is a declaration for a
20775 limited derived record before analyzing components.
20776 (Analyze_Component_Declaration): Diagnose record types not explicitly
20777 declared limited when a component has a limited type.
20778 (Build_Derived_Record_Type): Code reorganization to check if some of
20779 the inherited subprograms of a tagged type cover interface primitives.
20780 This check was missing in case of a full-type associated with a private
20782 (Constant_Redeclaration): Check that the subtypes of the partial and the
20783 full view of a constrained deferred constant statically match.
20784 (Mentions_T): A reference to the current type in an anonymous access
20785 component declaration must be an entity name.
20786 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20787 class_wide type to refer to full type, not to the incomplete one.
20788 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20789 available. Required to give support to the certified run-time.
20790 (Analyze_Component_Declaration): In case of anonymous access components
20791 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20792 (Process_Discriminants): For an access discriminant, use the
20793 discriminant specification as the associated_node_for_itype, to
20794 simplify accessibility checks.
20796 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20797 Javier Miranda <miranda@adacore.com>
20799 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20800 abstract interpretations on an operator, remove interpretations that
20801 yield Address or a type derived from it, if one of the operands is an
20803 (Try_Object_Operation.Try_Primitive_Operation,
20804 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20805 location when creating the new reference to a primitive or class-wide
20806 operation as a part of rewriting a subprogram call.
20807 (Try_Primitive_Operations): If context requires a function, collect all
20808 interpretations after the first match, because there may be primitive
20809 operations of the same type with the same profile and different return
20810 types. From code reading.
20811 (Try_Primitive_Operation): Use the node kind to choose the proper
20812 operation when a function and a procedure have the same parameter
20814 (Complete_Object_Operation): If formal is an access parameter and prefix
20815 is an object, rewrite as an Access reference, to match signature of
20816 primitive operation.
20817 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20818 by an expanded name with prefix Standard, when the operands are of an
20819 anonymous access type.
20820 (Remove_Abstract_Operations): If the operation is abstract because it is
20821 inherited by a user-defined type derived from Address, remove it as
20822 well from the set of candidate interpretations of an overloaded node.
20823 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20826 2006-02-13 Bob Duff <duff@adacore.com>
20828 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20829 redundant use clauses.
20830 In particular, if the scope of two use clauses overlaps, but one is not
20831 entirely included in the other, we should not warn. This can happen
20832 with nested packages.
20833 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20834 reported errors. The bug was reported when the compiler was built
20835 with assertions enabled.
20836 (Find_Type): If the node is a 'Class reference and the prefix is a
20837 synchronized type without a corresponding record, return the type
20840 2006-02-13 Javier Miranda <miranda@adacore.com>
20842 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20843 if this is the full-declaration associated with a private declaration
20844 that implement interfaces, then the private type declaration must be
20846 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20847 as aliased. The use of the 'access attribute is not available for such
20848 object (for this purpose the object should be explicitly marked as
20849 aliased, but being an anonymous type this is not possible).
20851 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20852 Robert Dewar <dewar@adacore.com>
20854 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20855 compilation unit is an elaboration scope.
20856 (Add_Task_Proc): Add '\' in 2-line warning message.
20857 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20859 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20860 Javier Miranda <miranda@adacore.com>
20862 * sem_type.adb (Write_Overloads): Improve display of candidate
20864 (Add_One_Interp): Do not add to the list of interpretations aliased
20865 entities corresponding with an abstract interface type that is an
20866 immediate ancestor of a tagged type; otherwise we have a dummy
20867 conflict between this entity and the aliased entity.
20868 (Disambiguate): The predefined equality on universal_access is not
20869 usable if there is a user-defined equality with the proper signature,
20870 declared in the same declarative part as the designated type.
20871 (Find_Unique_Type): The universal_access equality operator defined under
20872 AI-230 does not cover pool specific access types.
20873 (Covers): If one of the types is a generic actual subtype, check whether
20874 it matches the partial view of the other type.
20876 2006-02-13 Thomas Quinot <quinot@adacore.com>
20878 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20879 line. This is necessary to allow In_Extended_Main_Unit to provide
20880 correct results for itypes while writing out expanded source.
20881 (Close_File): No need to update the source_index_table here since it's
20882 now done for each line.
20884 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20885 Robert Dewar <dewar@adacore.com>
20887 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20888 preserve the source unit where the itype is declared, and prevent a
20890 (Note_Implicit_Run_Time_Call): New procedure
20891 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20894 * sprint.ads: Document use of $ for implicit run time routine call
20896 2006-02-13 Quentin Ochem <ochem@adacore.com>
20898 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20901 2006-02-13 Bob Duff <duff@adacore.com>
20903 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20904 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20905 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20906 raise Constraint_Error.
20908 * s-vallli.adb (Scan_Long_Long_Integer): Call
20909 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20910 do not scan leading blanks and sign twice.
20911 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20912 raise Constraint_Error.
20914 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20915 Scan_Long_Long_Unsigned): Split out most of the processing from
20916 Scan_Long_Long_Unsigned out into
20917 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20918 This prevents scanning leading blanks and sign twice.
20919 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20922 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20923 out most of the processing from Scan_Unsigned out into
20924 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20925 This prevents scanning leading blanks and sign twice.
20927 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20928 use with Modular'Value attribute.
20929 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20932 2006-02-13 Robert Dewar <dewar@adacore.com>
20934 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20936 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20938 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20939 (PPC VxWorks): Likewise.
20940 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20941 (forced_callee): Make non-inlinable and non-pure.
20942 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21058 Ada bind file prefix on VMS from b$ to b__.
21060 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
21061 --GCC so that Get_Target_Parameters can find system.ads.
21062 (Gnatlink): Call Get_Target_Parameters in mainline.
21063 Initialize standard packages for Targparm.
21064 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

21101 (Target_Object_Suffix): Initialize with target object suffix.
21103 * rident.ads: Add special exception to license.
21105 * targparm.adb (Get_Target_Parameters): Set the value of
21106 Multi_Unit_Index_Character after OpenVMS_On_Target gets its definitive
21108 (Get_Target_Parameters): Set OpenVMS_On_Target if openvms.

21127 * a-taster.ads, a-taster.adb: New files.
21129 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21130 link to the version that does nothing. This way the task termination
21131 routine is not executed twice for the environment task when finishing
21132 because of an unhandled exception.
21134 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21135 handler because of an unhandled exception.
21137 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21138 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21140 * s-finimp.adb (initialization code): Modify the soft link for the
21141 finalization of the global list instead of Adafinal.
21143 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21144 non-tasking version of the soft link for task termination. We do
21145 nothing since if we are using the non-tasking version it
21146 means that the task termination functionality is not used.
21147 (Null_Finalize_Global_List): Add this null version for the procedure
21148 in charge of finalizing the global list for controlled objects.
21149 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21150 instead for handling run-time termination in a more flexible way.
21151 (Adafinal_NT): This new procedure will take care of finalizing the
21152 global list for controlled objects if needed, but no tasking
21155 * s-tarest.adb (Task_Lock): Do not try to lock again the
21156 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21157 some run-time operations.
21158 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21159 until all nested locks have been released.
21160 (Task_Wrapper): Call the fall-back task termination handler. It
21161 applies to all tasks but the environment task.
21162 (Finalize_Global_Tasks): Add the call for the task termination
21163 procedure for the environment task.
21164 (Task_Wrapper): suppress warnings around declaration of
21165 Secondary_Stack_Address.
21167 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21168 moved to the Common_ATCB record.
21169 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21170 Common_ATCB record.
21171 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21172 Common_ATCB record.
21174 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21175 Fall_Back_Handler, and Specific_Handler.
21177 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21178 defined in Ada.Task_Termination, to avoid circular dependencies.
21179 (Termination_Handler): Redefine this type here, alredy defined in
21180 Ada.Task_Termination, for avoiding circular dependencies.
21181 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21182 for storing task termination handlers. In addition,
21183 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21184 Common_ATCB because it is used by both the regular and the restricted
21186 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21187 Common_ATCB because it is used by both the regular and the restricted
21189 (Common_ATCB): Added a dynamic task analyzer field.
21191 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking

21196 environment task. The call to Finalize_Global_List is now performed
21197 using the soft links mechanism.
21198 (Task_Wrapper): added dynamic stack analysis.
21200 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21201 potentially blocking operations has been moved from
21202 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21203 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21204 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21205 this run-time check.

21251 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21252 to the specification because the frontend generates code that uses this
21254 (Set_Interface_Table): Add missing assertion.
21255 Update documentation describing the run-time structure.
21256 (Displace): New subprogram that displaces the pointer to the object
21257 to reference one of its secondary dispatch tables.
21258 (IW_Membership): Modified to use the new table of interfaces.
21259 (Inherit_TSD): Modified to use the new table of interfaces.
21260 (Register_Interface_Tag): Use the additional formal to fill the

21279 record component containing the tag of the secondary dispatch table we
21280 have to use the Offset_To_Top run-time function to get this information;
21281 otherwise if the pointer to the base of the object has been displace
21282 we get a wrong value if we use the 'position attribute.
21284 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21285 all the calls to Expand_Interface_Thunk.
21286 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21289 ensure that the interfaces implemented by the ancestors are placed
21290 at the header of the generated list.
21291 (Expand_Interface_Conversion): Handle the case in which the displacement
21292 associated with the interface conversion is not statically known. In

21320 RE_TK_Tagged, RE_TK_Task.
21322 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21323 Init_Secondary_Tags_Internal to allow its use with interface types and
21324 also to generate the code for the new additional actual required
21325 by Set_Offset_To_Top.
21326 (Build_Init_Statements): In case of components associated with abstract
21327 interface types there is no need to generate a call to its IP.
21328 (Freeze_Record_Type): Generate Select Specific Data tables only for
21330 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21331 the bodies and specifications of the predefined primitive operations

21337 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21338 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21339 properly protected objects and attach handler in the case of the
21340 restricted profile.
21341 Move embeded package Select_Expansion_Utilities into a separate external

21353 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21354 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21355 about the use and expansion of SAVE_EXPRs in the various possible
21356 renaming handling cases.
21357 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21358 abusing DECL_FCONTEXT.

21460 2005-12-09 Robert Dewar <dewar@adacore.com>
21462 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

21477 component associated with the secondary table of an abstract interface
21478 type, return the entity associated with such abstract interface type.
21479 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21480 base type to create anonymous subtype, because entity may be a locally
21481 declared subtype or generic actual.
21482 (Find_Interface): New subprogram that given a tagged type and one of its
21483 component associated with the secondary table of an abstract interface
21484 type, return the entity associated with such abstract interface type.

21526 legal within a protected type that implements an interface.
21527 (Collect_Interfaces): Do not add to the list the interfaces that
21528 are implemented by the ancestors.
21529 (Derived_Type_Declaration): If the parent of the full-view is an
21530 interface perform a transformation of the tree to ensure that it has
21531 the same parent than the partial-view. This simplifies the job of the
21532 expander in order to generate the correct object layout, and it is
21533 needed because the list of interfaces of the full-view can be given in
21535 (Process_Full_View): The parent of the full-view does not need to be
21536 a descendant of the parent of the partial view if both parents are
21538 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21539 "limited" the parent must be a limited type.

21553 (Process_Full_View): Improve the check for the "no hidden interface"
21554 rule as defined by AI-396.
21556 2005-12-09 Robert Dewar <dewar@adacore.com>

21613 available user-specified stream attributes on limited parameters to
21614 also test the type directly rather than only its underlying type (for

21616 attributes are visible at the point of the subprogram declaration.
21617 For Ada 2005, the error message is modified to indicate that the
21618 type's stream attributes must be visible (again, only for -gnat05).

21876 TARGET, as it has the form of a math expression, and some components
21877 may be platform-defined macros.
21878 For VxWorks, generate the OK and ERROR values.
21879 New constants giving the sizes of the components of C struct timeval.

21891 deal with different cases of static and dynamic elaboration checks (all
21892 checks does not count in the first case, but does in the second).

21898 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21899 elementary types using the operator in standard. It is cleaner not to
21900 modify the programmers intent, especially in the case of floating-point.
21901 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21902 it did not matter because we always rewrote a/=b to not(a=b).
21903 (Expand_Allocator_Expression): For an allocator expression whose nominal
21904 subtype is an unconstrained packed type, convert the expression to its
21905 actual constrained subtype.
21906 Implement warning for <= or >= where < or > not possible
21907 Fix to Vax_Float tests (too early in many routines, causing premature
21908 Vax_Float expansions.
21910 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21911 to be used with packages and generic packages as well as with

21926 Allow optional = after -gnatm
21927 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21928 longer sets Elaboration_Checks.
21929 Code to set warning mode moved to Sem_Warn
21930 so that it can be shared by pragma processing.
21932 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21935 * s-taprop-solaris.adb:
21936 Change some <= to =, to avoid new warning

21944 * exp_vfpt.adb: Handle /= case
21945 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21946 so that we do not get duplicate scaling for fixed point conversions.
21948 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
21950 2005-11-14 Matthew Gingell <gingell@adacore.com>
21952 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21953 Increase default priority on Lynx from 15 to 17, and meet the Ada
21954 requirement that Default_Priority be ((Priority'First +
21955 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22057 we are not defining the type.
22058 <E_Record_Type>: Likewise.
22059 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22060 to get advantage of the new maybe_stabilize_reference interface, to
22061 ensure that what we reference is indeed stabilized instead of relying
22062 on assumptions on what the stabilizer does.
22063 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22064 type imported through a limited_with clause, use its non-limited view.
22065 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22067 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22068 of #if sections + explicit comparisons of convention identifiers.

22070 before early-returning for certain types when code generation is
22072 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22074 that we are not defining.
22075 (elaborate_expression_1): Do not create constants when creating
22076 variables needed by the debug info: the dwarf2 writer considers that
22077 CONST_DECLs is used only to represent enumeration constants, and emits
22079 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22080 object with an address clause into an indirect reference, drop the
22081 initializing expression.

22092 if there is an actual subtype provided by the front-end, use that
22093 subtype to build an actual type with bounds template.
22094 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22095 is provided by the front-end, use that subtype to compute the size of
22096 the deallocated object.
22097 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22098 check for a potential violation of a No_Elaboration_Code restriction.
22099 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22100 with extra arguments to control whether to recurse through non-values
22101 and to let the caller know if the stabilization has succeeded.

22103 maybe_stabilize, for common uses without restriction on lvalues and
22104 without need to check for the success indication.
22105 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22106 pass false instead of 0 as the FORCE argument which is a bool.
22107 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22108 attached to a renaming pointer has been properly stabilized, as no such
22109 object is attached otherwise.
22110 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22111 function uses the "target pointer" return mechanism.
22112 Reinstate conversion of the actual to the type of the formal
22113 parameter before any other specific treatment based on the passing
22114 mechanism. This turns out to be necessary in order for PLACEHOLDER
22115 substitution to work properly when the latter type is unconstrained.

22119 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22120 with extra arguments to control whether to recurse through non-values
22121 and to let the caller know if the stabilization has succeeded.
22123 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22124 static output of record constructor if all the components are constant.
22125 (gnat_build_constructor): For a record type, sort the list of field
22126 initializers in increasing bit position order.
22127 Factor common code to build a storage type for an unconstrained object
22128 from a fat or thin pointer type and a constrained object type.
22129 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22130 types variants, and process special cases of VIEW_CONVERT expressions
22131 as their NOP_EXPR counterpart to ensure we get to the
22132 CORRESPONDING_VARs associated with CONST_DECls.
22133 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22134 on the right-hand side.

22141 extracting the object if converting to a type variant.
22142 (create_var_decl): When a variable has an initializer requiring code
22143 generation and we are at the top level, check for a potential violation
22144 of a No_Elaboration_Code restriction.
22145 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22146 SIZE and SIZE_UNIT which we need for later back-annotations.
22147 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
22148 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22149 is an unchecked union.
22150 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22151 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22152 main variant, just replace the VIEW_CONVERT_EXPR.

22331 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22332 'Unrestricted_Access, if the designated type is an interface we

22335 Use Universal_Real instead of Long_Long_Float when we need a high
22336 precision float type for the generated code (prevents gratuitous
22337 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22338 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22339 'Terminated for task interface class-wide objects. Generate a call to
22340 the predefined dispatching routine used to retrieve the _task_id from

22369 (Expand_N_Return_Statement): When returning a mutable record, convert
22370 the return value into its actual subtype in order to help the backend

22401 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22421 attribute of the N_Free_Statement.
22422 Generate itype for classwide designated object in both cases of
22423 user-specified storage pool: specific and class-wide, not only in the
22425 Raise CE when trying to set a not null access type object to null.

22639 Package_Instantiation field.
22640 (Get_Package_Instantiation_Node): Move declaration to package spec.
22641 Retrieve the N_Package_Instantiation node when the Package_Instantiation
22643 (Check_Generic_Child_Unit): Within an inlined call, the only possible
22644 instantiation is Unchecked_Conversion, for which no parents are needed.
22645 (Inline_Instance_Body): Deinstall and record the use_clauses for all
22646 parent scopes of a scope being removed prior to inlining an instance
22648 (Analyze_Package_Instantiation): Do not perform front-end inlining when
22649 the current context is itself an instance within a non-instance child
22650 unit, to prevent scope stack errors.
22651 (Save_References): If the node is an aggregate that is an actual in a
22652 call, rewrite as a qualified expression to preserve some type
22653 information, to resolve possible ambiguities in the instance.
22654 (Instance_Parent_Unit): New global variable to record the ultimate
22655 parent unit associated with a generic child unit instance (associated
22656 with the existing Parent_Unit_Visible flag).

22663 not already set. Replace test of Is_Child_Unit with test of parent's
22664 scope against package Standard. Add comments and a ??? comment.
22665 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22666 on a child instance parent to test that the parent equals

22681 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
22683 (Build_Private_Derived_Type): The entity of the created full view of the
22684 derived type does not come from source. If after installing the private
22685 declarations of the parent scope the parent is still private, use its
22686 full view to construct the full declaration of the derived type.
22687 (Build_Derived_Record_Type): Relax the condition that controls the
22688 execution of the check that verifies that the partial view and
22689 the full view agree in the set of implemented interfaces. In
22690 addition, this test now only takes into account the progenitors.
22691 (Derive_Interface_Subprograms): No need to derive subprograms
22692 of ancestors that are interfaces.
22693 (Derive_Subprograms): Remove formal No_Predefined_Prims and the

22697 view is a transitive derivation of the ancestor of the partial view.
22698 (Process_Full_View): Rename local subprogram Find_Interface_In_
22699 Descendant to Find_Ancestor_Interface to leave the code more clear.
22700 Remove wrong code that avoids the generation of an error message
22701 when the immediate ancestor of the partial view is an interface.
22702 In addition some minor reorganization of the code has been done to
22703 leave it more clear.
22704 (Analyze_Type_Declaration): If type has previous incomplete tagged
22705 partial view, inherit properly its primitive operations.
22706 (Collect_Interfaces): Make public, for analysis of formal

22714 (Access_Type_Declaration): Clean up declaration of malformed type
22715 declared as an access to its own classwide type, to prevent cascaded
22717 (Collect_Interfaces): For private extensions and for derived task types
22718 and derived protected types, the parent may be an interface that must
22719 be included in the interface list.
22720 (Access_Definition): If the designated type is an interface that may
22721 contain tasks, create Master_Id for it before analyzing the expression
22722 of the declaration, which may be an allocator.
22723 (Record_Type_Declaration): Set properly the interface kind, for use
22724 in allocators, the creation of master id's for task interfaces, etc.

22732 appear immediately after a subprogram body, when there is no previous
22733 subprogram declaration.
22734 Change name Is_Package to Is_Package_Or_Generic_Package
22735 (Process_Formals): A non null qualifier on a non null named access
22736 type is not an error, and is a warning only if Redundant_Constructs

22740 Ed Schonberg <schonberg@adacore.com>
22742 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
22743 nested within Analyze_Package_Specification to install the private
22744 declarations and use clauses within each of the parent units of a
22745 package instance of a generic child package.
22746 (Analyze_Package_Specification): When entering a private part of a
22747 package associated with a generic instance or formal package, the
22748 private declarations of the parent must be installed (by calling new
22749 procedure Install_Parent_Private_Declarations).
22750 Change name Is_Package to Is_Package_Or_Generic_Package
22751 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22752 record is absent in a generic context, which does not indicate a
22755 2005-11-14 Ed Schonberg <schonberg@adacore.com>
22757 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22758 not try to rewrite a renamed stream attribute, because the operations
22759 on the type may not have been generated.
22760 Handle properly a renaming_as_body generated for a stream operation
22761 whose default is abstract because the object type itself is abstract.
22762 (Find_Type): If the type is incomplete and appears as the prefix of a
22763 'Class reference, it is tagged, and its list of primitive operations
22764 must be initialized properly.
22765 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22766 private declaration of a parent unit, prior to compiling the private
22767 part of a child unit, find on the scope stack the proper parent entity
22768 on which to link the use clause.
22769 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22771 (Analyze_Object_Renaming): An attribute reference is not a legal object
22772 if it is not a function call.

22788 * sem_res.adb (Resolve_Call): Provide a better error message whenever
22789 a procedure call is used as a select statement trigger and is not an
22790 entry renaming or a primitive of a limited interface.
22791 (Valid_Conversion): If the operand has a single interpretation do not
22792 remove address operations.
22793 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22794 statement to inhibit warning.
22795 (Resolve_Unary_Op): Do not produce a warning when
22796 processing an expression of the form -(A mod B)
22797 Use Universal_Real instead of Long_Long_Float when we need a high
22798 precision float type for the generated code (prevents gratuitous
22799 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22800 (Resolve_Concatenation_Arg): Improve error message when argument is an
22801 ambiguous call to a function that returns an array.
22802 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22803 there is an implicit operator in the given scope if we are within an
22804 instance: legality check has been performed on the generic.

23386 (Expand_Allocator_Expression): Add tests for suppression of the AI-344
23387 check for proper accessibility of the operand of a class-wide allocator.
23388 The check can be left out if checks are suppressed or if the expression

23742 2005-09-01 Robert Dewar <dewar@adacore.com>
23744 * checks.adb (Check_Needed): New procedure, deals with removing checks
23745 based on analysis of short-circuited forms. Also generates warnings for
23746 improper use of non-short-circuited forms.
23749 2005-09-01 Robert Dewar <dewar@adacore.com>
23751 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
23754 2005-09-01 Robert Dewar <dewar@adacore.com>
23756 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

23760 (conditional warning).
23761 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
23762 (Error_Msg_Warn): New variable for < insertion char.
23763 * prj-nmsc.adb: Implement new errout insertion char < (conditional
23765 (Check_For_Source): Change value of Source_Id only after the current
23766 source has been dealt with.
23768 2005-09-01 Robert Dewar <dewar@adacore.com>
23769 Doug Rupp <rupp@adacore.com>
23771 * exp_attr.adb: Handle vax fpt for 'Valid attribute

23777 Hristian Kirtchev <kirtchev@adacore.com>
23778 Javier Miranda <miranda@adacore.com>
23780 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23781 from object notation, the original node is unanalyzed and carries no
23782 semantic information, so that accessiblity checks must be performed on
23783 the type of the actual itself.
23784 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23785 compatibility with Build_Protected_Sub_Specification.
23786 (Check_Overriding_Inherited_Interfaces): Add suport to handle
23787 overloaded primitives.
23788 (Register_Interface_DT_Entry): Use the new name of the formal
23789 the the calls to Expand_Interface_Thunk
23791 * exp_dbug.ads: Augment comments on encoding of protected types to
23792 include the generation of dispatching subprograms when the type
23793 implements at least one interface.
23795 * lib.ads: Extend information in Load_Stack to include whether a given
23796 load comes from a Limited_With_Clause.
23798 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23799 whether a potential circularity is harmless, because it includes units
23800 loaded through a limited_with clause. Extends previous treatment which
23801 did not handle properly arbitrary combinations of limited and
23802 non-limited clauses.
23804 2005-09-01 Nicolas Setton <setton@adacore.com>
23806 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23807 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23808 typ___XB_lowerbound__upperbound.
23810 2005-09-01 Thomas Quinot <quinot@adacore.com>
23812 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23813 dummy access formal for RACW/RAS TypeCode TSS.
23814 (Build_TypeCode_Call): Do not generate dummy null access actual for
23815 calls to the TypeCode TSS.
23817 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23819 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23820 fully qualified name, to distinguish instances with the same local name.
23822 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
23825 2005-09-01 Robert Dewar <dewar@adacore.com>

23832 * g-expect.adb (Non_Blocking_Spawn): Initialize the filters field to
23833 (Free): New deallocation procedure for filter elements
23834 (Close): Deallocate any existing filter for the concerned connection
23836 2005-09-01 Laurent Pautet <pautet@adacore.com>
23838 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23839 position set is provided, we compute one in order to reduce the maximum
23840 length of the keys. This computation first selects a character
23841 position between 1 and the minimum length of the keys in order to
23842 avoid reducing one of the keys to an empty string.
23843 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23844 does not converge. The initialization procedure now comes with a
23845 maximum number of iterations such that when exceeded, an exception is
23846 raised in Compute. The user can initialize this ratio to another value
23848 Reformating and updated headers.
23850 2005-09-01 Javier Miranda <miranda@adacore.com>
23852 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23853 that given an entity T creates and returns an Itype that duplicates the
23854 contents of T. The returned Itype has the null-exclusion
23855 attribute set to True, and its Etype attribute references T
23856 to keep the association between the two entities.
23857 Update copyright notice
23859 * sem_aggr.adb (Check_Can_Never_Be_Null,
23860 Aggregate_Constraint_Checks, Resolve_Aggregate,
23861 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23863 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23866 Robert Dewar <dewar@adacore.com>
23867 Hristian Kirtchev <kirtchev@adacore.com>

23876 plus null exclusions. Call Set_Result_Definition instead of
23879 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23880 (P_Access_Type_Definition): Add parsing for an anonymous access result
23881 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23882 instead of Set_Subtype_Mark.
23884 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23885 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23886 (Result_Definition): New function for N_Function_Specifications.
23887 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23888 N_Function_Specification.
23889 (Set_Null_Exclusion_Present): Allow this flag for
23890 N_Function_Specification.
23891 (Set_Result_Definition): New procedure for N_Function_Specifications.
23892 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23893 and N_Function_Specification.
23895 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23896 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23897 Add support for LIMITED NEW for Ada 2005 AI-419
23898 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23899 syntax for anonymous access results.
23900 Replace Subtype_Mark field by Result_Definition in
23901 N_Function_Specification and N_Access_Definition specs.
23902 Add Null_Exclusion_Present to spec of N_Function_Specification.
23903 (Result_Definition): New function for N_Function_Specification and
23904 N_Access_Function_Definition.
23905 (Set_Result_Definition): New procedure for N_Function_Specification and
23906 N_Access_Function_Definition.
23908 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23909 Result_Definition for cases of N_Access_Function_Definition and
23910 N_Function_Specification.
23911 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23913 2005-09-01 Vincent Celier <celier@adacore.com>
23915 * lib-writ.adb: Update Copyright notice
23916 (Write_With_Lines): On platforms where file names are case-insensitive,
23917 record the file names in lower case.
23918 (Write_ALI): For D lines, on platforms where file names are
23919 case-insensitive, record the file names in lower case.
23921 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23922 Emmanuel Briot <briot@adacore.com>
23924 * lib-xref.adb (Output_Overridden_Op): Display information on
23925 overridden operation.
23927 * lib-xref.ads: Add documentation on overridden operations.
23929 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23932 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23933 overriding entity information.
23935 2005-09-01 Vincent Celier <celier@adacore.com>
23937 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23938 including those that are inherited.
23940 2005-09-01 Robert Dewar <dewar@adacore.com>
23942 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23944 * par-prag.adb: Implement new pragma Debug_Policy
23946 * sem_prag.adb Implement new pragma Debug_Policy
23947 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23948 Component_Size attribute specification. Give warning for ignored pragma
23951 * snames.h, snames.ads, snames.adb: Introduce entries in
23952 Preset_Names for Name_Disp_Asynchronous_Select,
23953 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23954 Name_Disp_Timed_Select.
23955 New pragma Debug_Policy
23957 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23959 Switch -gnata also sets Debug_Pragmas_Enabled
23961 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23962 handle an explicit -gnata when compiling predefined files.
23964 2005-09-01 Vincent Celier <celier@adacore.com>
23966 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23967 directories of projects that have no Ada sources.
23969 2005-09-01 Robert Dewar <dewar@adacore.com>
23971 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23972 (makes a difference for wide characters)
23974 * widechar.adb, widechar.ads:
23975 Add Wide_Char_Byte_Count feature to count chars vs bytes
23977 2005-09-01 Thomas Quinot <quinot@adacore.com>
23978 Ed Schonberg <schonberg@adacore.com>
23979 Robert Dewar <dewar@adacore.com>
23981 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23982 'Address attribute reference with an overloaded prefix, use the
23983 location of the prefix (not the location of the attribute reference) as
23984 the error location.
23985 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23986 a function renaming thereof, is a valid prefix for 'Size (where it is
23987 intepreted as a function call).
23988 (Statically_Denotes_Entity): New predicate to determine whether the
23989 prefix of an array attribute can be considered static.
23992 (Eval_Attr): Fix failure to evaluate Component_Size for
23993 unconstrained arrays (resulted in wrong value in packed case, since
23994 back end cannot handle this case)
23996 2005-09-01 Robert Dewar <dewar@adacore.com>
23998 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23999 error msgs for most common cases.
24000 Use new errout insertion char < (conditional warning)
24002 2005-09-01 Javier Miranda <miranda@adacore.com>
24003 Ed Schonberg <schonberg@adacore.com>
24005 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24006 become local to the whole package.
24007 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24008 the package was already analyzed the new algorithm "replaces" the
24009 real entities by the shadow ones. This is required to ensure that
24010 the order of these entities in the homonym chains does not change;
24011 otherwise we can have undefined references at linking time because
24012 in case of conflicts the external name of the entities will have
24013 a suffix that depends on the order of the entities in the chain.
24014 (Remove_Limited_With_Clause): Complementary code that completes the
24015 new algorithm and replaces the shadow entities by the real ones.
24016 (Install_Limited_Withed_Unit): When unchaining entities before the
24017 installation of the shadow entities, only regular entities of the
24018 public part must be taken into account. This is required to
24019 keep this routine in synch with the work done by Remove_Limited_
24021 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24022 even if unit is analyzed, because the analysis of the unit is
24023 idempotent in any case, and the limited view of the unit may have to
24024 be installed for proper visibility.
24025 (Expand_Limited_With_Clause): Even if the unit in the implicit
24026 with_clause has been analyzed already, a limited view of the package
24027 must be built for the current context, if it does not exist yet.
24029 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24030 Javier Miranda <miranda@adacore.com>
24031 Gary Dismukes <dismukes@adacore.com>
24033 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24034 defining entity for the instance body, make a new defining identifier
24035 rather than copying the entity of the spec, to prevent accidental
24036 sharing of the entity list.
24037 (Check_Private_View): When exchanging views of private types, build the
24038 list of exchanged views as a stack, to ensure that on exit the exchanges
24039 are undone in the proper order.
24040 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24041 Restore the compilation environment in case of instantiation_error.
24042 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24043 for an anonymous access result.
24044 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24045 (Formal_Entity): Handle properly the case of a formal package that
24046 denotes a generic package renaming.
24048 2005-09-01 Thomas Quinot <quinot@adacore.com>
24050 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24051 clause if the array aggregate is surrounded by parentheses.
24053 2005-09-01 Cyrille Comar <comar@adacore.com>
24054 Gary Dismukes <dismukes@adacore.com>
24055 Ed Schonberg <schonberg@adacore.com>
24056 Javier Miranda <miranda@adacore.com>
24058 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24060 to check if a type is Constrained in cases related to code generation
24061 (rather than semantic checking) since otherwise we do not generate
24062 similar code for mutable private types depending if their
24063 discriminants are visible or not.
24064 (Check_Abstract_Overriding): Do not complain about failure to override
24065 the primitive operations used in dispatching selects since they will
24066 always be overriden at the freeze point of the type.
24067 (Access_Definition): Separate out handling for resetting the scope
24068 of an anonymous access function result type. Retrieve the scope
24069 of the associated function rather than using Current_Scope, which
24070 does not have a consistent value (depends on whether we're in the
24071 middle of analyzing formal parameters). Add ??? comment about
24072 finding a cleaner way to handle the special cases of scope setting.
24073 (Process_Incomplete_Dependents): A protected operation is never a
24074 dispatching operation (only its wrapper may be).
24075 (Build_Derived_Record_Type): In case of tagged private types that
24076 implement interfaces add derivation of predefined primitive
24078 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24079 by two parameters that are used in case of derivation from abstract
24080 interface types: No_Predefined_Prims is used to avoid the derivation
24081 of predefined primitives from the interface, and Predefined
24082 Prims_Only is used to complete the derivation predefined primitives
24083 in case of private tagged types implementing interfaces.
24084 Fix typo in comments
24085 (Find_Interface_In_Descendant): Protect the frontend against
24086 wrong code with large circularity chains.
24087 (Is_Private_Overriding): Add support for entities overriding interface
24088 subprograms. The test failed because Entities associated with overriden
24089 interface subprograms are always marked as hidden (and used to build
24090 the secondary dispatch table); in this case the overriden entity is
24091 available through the field abstract_interface_alias (cf. override_
24092 dispatching_operation)
24093 (Access_Definition): Set the scope of the type to Current_Scope for the
24094 case of a function with an anonymous access result type.
24095 (Access_Subprogram_Declaration): Handle creation of the type entity for
24096 an access-to-function type with an anonymous access result.
24097 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24098 in handling for N_Access_Function_Definition.
24099 (Analyze_Subtype_Declaration): Modify the text of error message.
24100 (Derived_Type_Declaration): Modify the text of error message.
24101 (Process_Subtype): Modify the text of error message plus cleanup
24102 of one redundant error message.
24103 (Analyze_Component_Declaration): Code cleanup.
24104 (Analyze_Object_Declaration): Code cleanup.
24105 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24106 attribute in case of access types. Code cleanup.
24107 (Array_Type_Declaration): Code cleanup.
24108 (Process_Discriminants): Create the new null-excluding itype
24109 if required. Code cleanup.
24110 (Process_Subtype): Create the new null-excluding itype if
24111 required. Code cleanup.
24112 (Build_Derived_Record_Type): Code cleanup to avoid calling
24113 twice the subprogram derive_subprograms in case of private
24114 types that implement interfaces. In this particular case the
24115 subprogram Complete_Subprograms_Derivation already does the
24116 job associated with the second call.
24118 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24119 conversion to the full view when generating an operation for a
24120 discriminant whose type may currently be private.
24122 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24123 Javier Miranda <miranda@adacore.com>
24125 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24126 V (Obj.F), the rewriting does not involve the indexed component, but
24127 only the selected component itself.
24128 Do not apply the transformation if the analyzed node is an actual of a
24129 call to another subprogram.
24130 (Complete_Object_Operation): Retain the entity of the
24131 dispatching operation in the selector of the rewritten node. The
24132 entity will be used in the expansion of dispatching selects.
24133 (Analyze_One_Call): Improve location of the error message associated
24135 (Analyze_Selected_Component): No need to resolve prefix when it is a
24136 function call, resolution is done when parent node is resolved, as
24138 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24139 when attempting to resolve a call transformed from its object notation.
24140 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24141 of the argument list for each interpretation of the operation.
24142 (Try_Object_Operation): The designated type of an access parameter may
24143 be an incomplete type obtained through a limited_with clause, in which
24144 case the primitive operations of the type are retrieved from its full
24146 (Analyze_Call): If this is an indirect call, and the return type of the
24147 access_to_subprogram is incomplete, use its full view if available.
24149 2005-09-01 Javier Miranda <miranda@adacore.com>
24150 Gary Dismukes <dismukes@adacore.com>
24152 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24153 access types the null-exclusion and access-to-constant attributes must
24155 (Analyze_Return_Statement): When the result type is an anonymous access
24156 type, apply a conversion of the return expression to the access type
24157 to ensure that appropriate accessibility checks are performed.
24158 (Analyze_Return_Type): For the case of an anonymous access result type,
24159 generate the Itype and set Is_Local_Anonymous_Access on the type.
24160 Add ??? placeholder for check to disallow returning a limited object
24161 in Ada 2005 unless it's an aggregate or a result of a function call.
24162 Change calls from Subtype_Mark to Result_Definition.
24163 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24164 Result_Definition in call to Make_Function_Specification.
24165 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24166 Set_Result_Definition.
24167 (Make_Inequality_Operator): Change formal Subtype_Mark to
24168 Result_Definition in call to Make_Function_Specification.
24169 (Process_Formals): Create the new null-excluding itype if required.
24170 (New_Overloaded_Entity): For an entity overriding an interface primitive
24171 check if the entity also covers other abstract subprograms in the same
24172 scope. This is required to handle the general case, that is, overriding
24173 other interface primitives and overriding abstract subprograms inherited
24174 from some abstract ancestor type.
24175 (New_Overloaded_Entity): For an overriding entity that comes from
24176 source, note the operation that it overrides.
24177 (Check_Conformance, Type_Conformant): Addition of one new formal
24178 to skip controlling formals in the analysis. This is used to
24179 handle overloading of abstract interfaces.
24180 (Base_Types_Match): Add missing case for types imported from
24181 limited-with clauses
24182 (New_Overloaded_Entity): Add barrier to protect the use of
24183 the "alias" attribute.
24185 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24187 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24188 verify that the procedure and the entry are mode conformant.
24189 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24190 as a different operator, which is often a cut-and-paste error.
24192 2005-09-01 Javier Miranda <miranda@adacore.com>
24193 Ed Schonberg <schonberg@adacore.com>
24195 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24196 used in controlling parameters exclude null because it is necessary to
24197 read the tag to dispatch, and null has no tag.
24198 (Override_Dispatching_Operation): If the previous operation is inherited
24199 from an interface, it becomes hidden and does not participate in later

24206 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24207 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24208 the expander will generate the corresponding run-time check to evaluate
24210 (Resolve_Call): Check for legal type of procedure name or prefix that
24211 appears as a trigger in a triggering alternative.
24212 (Valid_Conversion): If expression is ambiguous and the context involves
24213 an extension of System, remove System.Address interpretations.
24214 (Resolve_Qualified_Expression): Reject the case of a specific-type
24215 qualification applied to a class-wide argument. Enhance comment
24216 to explain checking of Original_Node.
24217 (Resolve_Type_Conversion): The location of the error message was not
24218 general enough to handle the general case and hence it has been removed.
24219 In addition, this patch improves the text of the message.
24220 (Resolve_Type_Conversion): Add missing support for access to interface
24222 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24223 do not expand if the expression is the actual in a call, because proper
24224 expansion will take place when the call itself is expanded.
24225 (Resolve_Allocator): If the context is an unchecked conversion, the
24226 allocator inherits its storage pool, if any, from the target type of

24232 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24233 inherited interface operation that has an implementation, use the
24234 implementation to avoid spurious ambiguities.
24235 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24236 use the Corresponding_Record_Typ attribute to look for the interface
24237 because it is set by the expander (and hence it is not always
24238 available). For this reason we traverse the list of interfaces
24239 (available in the parent of the concurrent type).
24240 (Interface_Present_In_Ancestor): Handle entities from the limited view

24251 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24252 capture if it is generated in the second operand of a short-circuit
24254 Do not capture values for variables with address clauses.
24255 (Is_Object_Reference): Treat a function call as an object reference only
24256 if its type is not Standard_Void_Type.

25044 longer protected objects. They have been replaced by lower-level
25045 suspension objects made up by a mutex and a condition variable (or
25046 their equivalent given a particular OS) plus some internal data to
25047 reflect the state of the suspension object.

25424 misaligned because of packing or representation clauses.
25425 (Is_Legal_Copy): New predicate to determine whether a possibly
25426 misaligned in-out actual can actually be passed by copy/return. This
25427 is an error in case the type is by_reference, and a warning if this is
25428 the consequence of a DEC import pragma on the subprogram.
25429 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
25431 (Expand_Inlined_Call): Mark temporary generated for the return value as

25449 (Expand_Subtype_From_Expr): If the expression is a selected component
25450 within an initialization procedure, compute its actual subtype, because
25451 the component may depend on the discriminants of the enclosing record.
25453 * i-cpp.ads, i-cpp.adb:
25454 This package has been left available for compatibility with previous

25479 the generic that is created to represent the formal package.
25480 (Analyze_Package_Instantiation): Instantiate body immediately if the
25481 package is a predefined unit that contains inlined subprograms, and
25482 we are compiling for a Configurable_Run_Time.

25487 error message condition, null procedures are correctly detected now.
25488 (New_Overloaded_Entity): Bypass trivial overriding indicator check

25498 by the corresponding record type.
25499 (Analyze_Subprogram_Body): Undo the previous work.
25500 (Analyze_Procedure_Call): If the call has the form Object.Op, the

25504 subprogram_specification that returns true if some non
25505 class-wide interface subprogram is found

25508 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
25509 access to subprograms must be recursive.
25510 (Is_Unchecked_Conversion): Improve the test that recognizes
25511 instantiations of Unchecked_Conversion, and allows them in bodies that
25512 are to be inlined by the front-end. When the body comes from an
25513 instantiation, a reference to Unchecked_Conversion will be an
25514 Expanded_Name, even though the body has not been analyzed yet.

25533 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
25534 in the case where the target type is an anonymous access type of an
25535 object or component (that is, when Is_Local_Anonymous_Access is true).
25536 Prevent the special checks for conversions of access discriminants in
25537 the case where the discriminant belongs to a nonlimited type, since
25538 such discriminants have their accessibility level defined in the same
25539 way as a normal component of an anonymous access type.
25540 (Resolve_Allocator): When an allocator's designated type is a class-wide
25541 type, check that the accessibility level of type given in the
25542 allocator's expression or subtype indication is not statically deeper
25543 than the level of the allocator's access type.

25558 Call to obsolescent subprogram is now considered to be a violation of
25559 pragma Restrictions (No_Obsolescent_Features).
25560 (Check_Direct_Boolean_Operator): If the boolean operation has been
25561 constant-folded, there is nothing to check.
25562 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25563 check on possible violation of restriction No_Direct_Boolean_Operators
25564 until after expansion of operands, to prevent spurious errors when

25600 both bound checks, rather than a conjunction.
25601 (Insert_Valid_Check): If the expression is an actual that is an indexed
25602 component of a bit-packed array, force expansion of the packed element
25603 reference, because it is specifically inhibited elsewhere.

26569 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26570 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26571 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26572 analyzed if expansion is disabled (which could otherwise cause spurious
26573 error messages if expansion has been disabled due to previous
26574 (unrelated) errors).
26576 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26577 is disabled, the entity denoted by the argument is the access type
26578 itself, not an underlying record type, so there is no need to go back
26579 to the Corresponding_Remote_Type.
26581 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26582 Robert Dewar <dewar@adacore.com>
26584 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
26585 expand a call to an instance of
26586 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
26587 Constructor actual of the instance. A class-wide membership
26588 check is also generated, to ensure that the tag passed to the instance
26589 denotes a type in the class.
26590 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26591 of Name_Generic_Dispatching_Constructor.
26593 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26594 05 unit for AI-260-02).

26608 the case of renaming of stream attributes when the renaming denotes a
26609 generic formal subprogram association for an abstract formal subprogram.
26610 Check that the attribute is a primitive stream attribute (and not
26611 a class-wide stream attribute) and then rewrite the attribute name
26612 as the name of the appropriate compiler-generated stream primitive.
26614 2005-03-29 Robert Dewar <dewar@adacore.com>
26616 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26623 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26624 itype whose parent is controlled and not yet frozen, do not create a
26625 freeze node for the itype if expansion is disabled.
26627 2005-03-29 Vincent Celier <celier@adacore.com>
26629 * make.adb (Gnatmake): Don't fail if the main project file is declared
26630 as having no Ada sources. Do not display message "no sources to
26631 compile" in quiet output.
26633 2005-03-29 Doug Rupp <rupp@adacore.com>
26635 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26646 missing TYPE Improve the error message generated when compiling a
26647 limited interface in Ada83 or Ada95 mode.
26649 2005-03-29 Robert Dewar <dewar@adacore.com>
26651 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26652 rather than proceed ahead using a junk attribute name.
26654 2005-03-29 Vincent Celier <celier@adacore.com>
26656 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26658 * prj-part.adb (Parse_Single_Project): Set the location of a project
26659 on its defining identifier, rather than on the reserved word "project".
26661 * prj-proc.adb (Expression): Adapt to the fact that default of external
26662 references may be string expressions, not always literal strings.
26663 (Recursive_Process): Set Display_Name equal to Name
26664 when Location is No_Location, that is when there is no actual file.
26665 Get the Display_Name of the project from the source, when it is not a
26667 (Process): Use the Display_Name in error messages
26669 * prj-strt.adb (External_Reference): Allow default to be string
26670 expressions, not only literal strings.
26672 2005-03-29 Vincent Celier <celier@adacore.com>
26674 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
26675 file and the reference symbol file to be the same file.

26679 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26680 forbid conversion of a local access-to-subprogram type to a remote one.
26682 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26683 equivalent type for a remote access-to-subprogram type, go back to the
26684 original RAS entity when displaying an error message, so the casing is
26685 the original source casing.
26687 2005-03-29 Robert Dewar <dewar@adacore.com>
26689 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26692 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26694 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26695 subtype if code is being pre-analyzed, to prevent un-expanded
26696 references to protected formals, among others.
26697 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26698 interpretation that can be a call, include the result of the call as a
26699 possible interpretation of the dereference.
26701 * sem_ch5.adb (Process_Bounds): Determine type of range by
26702 pre-analyzing a copy of the original range, and then analyze the range
26703 with the expected type.
26705 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26706 with an overloaded prefix where not all interpretations yield an
26707 access to subprogram, do not rewrite node as a call.
26708 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26709 the node as a call once the context identifies the interpretation of
26710 the prefix whose call yields the context type.
26711 (Valid_Conversion): For the case of a conversion between
26712 local access-to-subprogram types, check subtype conformance using
26713 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26714 detailed error message.
26716 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26718 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26719 indicator, indicate that the formal can never be null.
26720 (Process_Formals): If a formal has a non_null indicator, insert the
26721 resulting subtype immediately before the enclosing subprogram decl,
26722 and not at the beginning of the corresponding declarative part, to
26723 prevent access before elaboration (Ada2005).

26832 to install the visible declarations of the enclosing scope of a
26833 record_type_with_private to establish the proper visibility before
26834 freezing the entity and related subprograms.

26844 (Check_Stream_Attribute): Move the code for 13.13.2(9/1) enforcement
26845 into a new Check_Attr subprogram, in order to provide a more
26846 explanatory error message (including the name of the missing attribute).
26847 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
26848 subprogram determines whether a default implementation exists for a
26849 given stream attribute.

27327 (Set_Task_Body_Procedure): New subprogram to set this attribute.
27328 (Has_Controlled_Component): Now applies to all entities.
27329 This is only a documentation change, since it always worked to apply
27330 this to other than composite types (yielding false), but now this is
27332 Update documentation on Must_Be_Byte_Aligned for new spec
27334 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27335 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27336 uses of the Access_Disp_Table attribute to reference the first dispatch
27337 table associated with a tagged type. As
27338 part of the implementation of abstract interface types,
27339 Access_Disp_Table has been redefined to contain a list of dispatch
27340 tables (rather than a single dispatch table).
27341 Similarly, upgrade all the references to Tag_Component by the
27342 new attribute First_Tag_Component.
27343 (Find_Inherited_TSS): Moved to exp_tss.
27344 Clean up test in Expand_N_Object_Declaration for cases
27345 where we need to do a separate assignment of the initial value.
27346 (Expand_N_Object_Declaration): If the expression in the
27347 declaration of a tagged type is an aggregate, no need to generate an
27348 additional tag assignment.
27349 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27351 Bit packed array ops are only called if operands are known to be
27353 (Component_Equality): When returning an N_Raise_Program_Error statement,
27354 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27355 expects that only expressions have a bona fide type).
27356 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27357 determine the amount of data to be copied.
27359 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27360 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
27361 INTERFACE_TYPE_DEFINITION ::=
27362 [limited | task | protected | synchronized] interface
27363 [AND interface_list]
27365 * par-ch3.adb (P_Type_Declaration): Modified to give support to
27367 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
27369 (P_Interface_Type_Definition): New subprogram that parses the new
27370 syntax rule of Ada 2005 interfaces
27371 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
27372 messages by the correct RENAMES (quotes removed).
27374 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
27375 attribute First_Tag_Component.
27377 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
27378 (Interface_List, Set_Interface_List): New subprograms.
27379 (Interface_Present, Set_Interface_Present): New subprograms.
27380 (Limited_Present, Set_Limited_Present): Available also in derived
27381 type definition nodes.
27382 (Protected_Present, Set_Protected_Present): Available also in
27383 record type definition and
27384 derived type definition nodes.
27385 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
27386 (Task_Present, Set_Task_Present): New subprogram.
27387 (Task_Body_Procedure): Removed.
27388 (Set_Task_Body_Procedure): Removed.
27389 These subprogram have been removed because the attribute
27390 Task_Body_Procedure has been moved to the corresponding task type
27391 or task subtype entity to leave a field free to store the list
27392 of interfaces implemented by a task (for AI-345)
27393 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27394 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27395 expression flag Do_Range_Check
27396 (Exception_Junk): Change to Flag7 to accomodate above change
27397 (Box_Present, Default_Name, Specification, Set_Box_Present,
27398 Set_Default_Name, Set_Specification): Expand the expression
27399 "X in N_Formal_Subprogram_Declaration" into the corresponding
27400 two comparisons. Required to use the csinfo tool.
27402 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
27403 "with string" given.
27405 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27408 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27411 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27412 attribute Task_Body_Procedure rather than the old semantic field that
27413 was available in the task_type_declaration node.
27415 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27416 interface type definitions.
27417 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27420 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27421 task type declaration.
27422 (P_Protected): Modified to handle the list of interfaces in a
27423 protected type declaration.
27425 2005-03-15 Doug Rupp <rupp@adacore.com>
27426 Vincent Celier <celier@adacore.com>
27428 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27429 (Gen_Output_File_C): Likewise.
27430 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27432 2005-03-15 Thomas Quinot <quinot@adacore.com>
27434 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27435 is an N_Raise_Constraint_Error node, create a new copy of it without
27436 going through a call to Duplicate_Subexpr.
27438 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27439 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27440 Nicolas Setton <setton@adacore.com>
27441 Ed Schonberg <schonberg@adacore.com>
27447 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27448 representation clause that prescribes a size not equal to the rounded
27449 size of their types.
27450 (gnat_to_gnu_entity, case E_Component): Always look at
27451 Original_Record_Component if Present and not the entity.
27452 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27453 of tagged extension types by not making field for components that are
27455 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27456 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27457 expression to the type of the object when the object is constant.
27458 Reverse defer_debug_incomplete_list before traversing it, so that trees
27459 are processed in the order at which they were added to the list. This
27460 order is important when using the stabs debug format.
27461 If we are deferring the output of debug information, also defer this
27462 output for a function return type.
27463 When adding fields to a record, prevent emitting debug information
27464 for incomplete records, emit the information only when the record is
27466 (components_to_record): New parameter defer_debug.
27467 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27468 (gnat_to_gnu_field_decl): New function.
27469 (substitution_list, annotate_rep): Call it.
27470 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27471 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27472 No longer update discriminants to not be a COMPONENT_REF.
27473 (copy_alias_set): Strip padding from input type; also handle
27474 unconstrained arrays properly.
27476 * gigi.h (write_record_type_debug_info): New function.
27477 Convert to use ANSI-style prototypes. Remove unused
27478 declarations for emit_stack_check, elab_all_gnat and
27479 set_second_error_entity.
27480 (gnat_to_gnu_field_decl): New decl.
27482 * utils.c (write_record_type_debug_info): New function.
27483 (finish_record_type): Delegate generation of debug information to
27484 write_record_type_debug_info.
27485 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27486 (update_pointer_to): Fix pasto.
27487 (convert) <UNION_TYPE>: Accept slight type variations when
27488 converting to an unchecked union type.
27490 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27491 replace the N_Freeze_Entity with a null statement.
27493 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27494 within a constrained subcomponent of an enclosing record, place the
27495 freeze nodes in the scope stack entry for the enclosing record.
27496 (Undelay_Type): New Subprogram.
27497 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27498 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27499 within records; allow them to have freeze nodes if their base types
27502 * exp_util.adb (Remove_Side_Effects): Properly test for
27503 Expansion_Delayed and handle case when it's inside an
27504 N_Qualified_Expression.
27506 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27507 Comes_From_Generic, to recognize accurately that the parent type in a
27508 derived type declaration can be traced back to a formal type, because
27509 it is one or is derived from one, or because its completion is derived
27511 (Constrain_Component_Type): If component comes from source and has no
27512 explicit constraint, no need to constrain in in a subtype of the
27514 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27515 Minor change to propagate Is_Ada_2005 flag
27517 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27518 Expansion_Delayed is False.
27519 (assoc_to_constructor): Ignore fields that have a
27520 Corresponding_Discriminant.
27521 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27522 function returns "by target", dereference the target pointer using the
27523 type of the actual return value.
27524 <all>: Be prepared for a null gnu_result.
27525 (processed_inline_subprograms): Check flag_really_no_inline
27526 instead of flag_no_inline.
27527 (set_second_error_entity): Remove unused function.

27532 2005-03-15 Robert Dewar <dewar@adacore.com>
27533 Ed Schonberg <schonberg@adacore.com>
27534 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27536 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27537 Must_Be_Byte_Aligned for cases where we do not need to use a
27538 System.Pack_nn unit.
27540 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27542 Needed now that we do some processing for IN parameters as well. This
27543 may well fix some unrelated errors.
27544 (Expand_Call): Handle case of unaligned objects (in particular those
27545 that come from packed arrays).
27546 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27547 renamed entity is an inherited operation, re-expand the call using the
27548 original operation, which is the one to call.
27549 Detect attempt to inline parameterless recursive subprogram.
27550 (Represented_As_Scalar): Fix to work properly with private types
27551 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27552 accurate estimate. Yields True in far fewer cases than before,
27553 improving the quality of code that depends on this test.
27555 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27556 over both visible and private declarations to remove them from tree,
27557 and mark subprograms declared in package as eliminated, to prevent
27558 spurious use in subsequent compilation of generic units in the context.
27560 * exp_util.ads: Minor cleanup in variable names
27562 * sem_eval.ads, sem_eval.adb: Minor reformatting
27563 (Compile_Time_Known_Bounds): New function
27565 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27567 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27568 determining whether an unchecked conversion is needed for the argument
27569 of an initialization call.
27571 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27573 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27574 that appears in the instantiation rather than the internal subtype
27575 generated in the wrapper package, to avoid anomalies in gigi when the
27576 target is derived from a private type whose full view is an access type.
27578 2005-03-15 Robert Dewar <dewar@adacore.com>
27580 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27582 Add documentation to replace the use of this flag
27583 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27586 2005-03-15 Thomas Quinot <quinot@adacore.com>
27588 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27589 here from exp_attr so it can be shared between exp_attr and exp_dist.
27590 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27591 all TSS names, not a subset thereof, and the previous name introduced
27592 an unnecessarily confusion that a distinction might exist between
27593 "OK" TSS names and some "not OK" TSS names.
27595 2005-03-15 Doug Rupp <rupp@adacore.com>
27597 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27600 2005-03-15 Pascal Obry <obry@adacore.com>
27601 Eric Botcazou <ebotcazou@adacore.com>
27605 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27606 when IN_RTS. This is to work around a bootstrap path problem.
27608 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27609 table and pass it to __gnat_install_SEH_handler().
27610 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27612 * lang.opt: Fix specification of -fRTS=.
27614 2005-03-15 Doug Rupp <rupp@adacore.com>
27615 Bernard Banner <banner@adacore.com>
27616 Vincent Celier <celier@adacore.com>
27617 Arnaud Charlet <charlet@adacore.com>
27620 This change works fine when gnatlib is built from the gcc directory,
27621 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27622 is not passed to ada/Makefile.in, so more work is needed by a
27623 Makefile/configure expert.
27625 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27626 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27627 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27629 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27630 Run ranlib on libgccprefix.a
27631 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27632 (ADA_INCLUDE_SRCS): Split Ada packages.
27634 2005-03-15 Robert Dewar <dewar@adacore.com>
27636 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27638 * impunit.adb: Add GNAT.UTF_32
27640 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27642 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27643 now uses GNAT.UTF_32).
27645 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27646 capabilities for categorizing characters using Unicode categories
27648 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27650 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27651 instantiation that has been rewritten as a package body, retrieve spec
27652 to generate proper name for implicit_with_clause.
27653 (Install_Parents): Recognize a parent that is an instantiation but has
27654 been rewritten as a package declaration during analysis.
27656 2005-03-15 Javier Miranda <miranda@adacore.com>
27657 Ed Schonberg <schonberg@adacore.com>
27659 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27660 parameter reported some error we immediately return. This improves the
27661 behaviour of the frontend in case of errors.
27662 (Install_Parent, Remove_Parent): Introduce new flag
27663 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27664 ancestor of a generic child unit, when the child is being instantiated.
27665 (Inline_Instance_Body): If we are compiling the private
27666 part or the body of a child unit, restore the proper visibility of the
27667 parents after compiling the instance body.
27669 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27670 Javier Miranda <miranda@adacore.com>
27673 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27674 of a private type, in which case it is underlying_type that denotes
27675 the proper task. Also modified to use the new entity attribute
27676 that is directly available in the task type and task subtype entities
27677 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27678 arrays when other dimensions than the first are constrained by
27679 discriminants of an enclosing record.
27680 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27681 a combination of indexed and selected components, find ultimate entity
27682 and generate the appropriate reference for it, to suppress spurious
27684 (Note_Possible_Modification): If an entity name has no entity, return.
27685 (Is_Variable): A function call never denotes a variable.
27686 (Requires_Transient_Scope): For record types, recurse only on
27687 components, not on internal subtypes that may have been generated for
27688 constrained components.
27690 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27692 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27693 Eliminated as candidates for resolution. Both efficient, and avoids
27694 anomalies with operators declared in deleted code.
27695 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27696 expansion is disabled (as when compiling a generic) to prevent spurious
27697 warnings on prefixes of selected components.
27699 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27701 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27702 attached to a list before checking whether it appears in the private
27703 declarations of the current package.
27704 (Make_Inequality_Operator): Insert declaration in proper declarative
27705 list rather than just setting the Parent field, so that
27706 Is_Private_Declaration can handle it properly.
27708 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27710 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27711 a renaming a body, check that the renamed subprogram in not intrinsic.
27712 (Find_Direct_Name): If several use_visible entities hide
27713 each other, and the context is a predefined file compiled through
27714 rtsfind, keep only the entity that comes from a predefined file.
27716 2005-03-15 Geert Bosch <bosch@adacore.com>
27718 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27719 long float padding to also cover AMD64 and IA64.
27721 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27723 * s-imgwch.adb: Add with and use of Interfaces.
27724 (Img_Wide_Character): Change type of Val to Unsigned_16.
27725 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27727 2005-03-15 Matthew Gingell <gingell@adacore.com>
27729 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27731 2005-03-15 Robert Dewar <dewar@adacore.com>
27733 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
27735 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27737 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
27739 2005-03-15 Robert Dewar <dewar@adacore.com>
27741 * s-bitops.adb, s-bitops.ads,

27762 * comperr.adb (Compiler_Abort): remove references to obsolete
27763 procedures in the bug boxes for various GNAT builds.
27765 2005-03-15 Vincent Celier <celier@adacore.com>
27767 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file

27772 Cyrille Comar <comar@adacore.com>
27773 Sergey Rybin <rybin@adacore.com>
27775 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27776 too specific and long-winded to be appropriate for the GNAT User's
27778 Warn about use of GCC switches not documented in the GNAT User's Guide,
27779 as these may cause generated code to not conform to Ada semantics.
27780 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
27781 Add documentation for -gnat95 and -gnat05 switches
27782 Remove paragraph documenting obsolete way to refer to third party
27784 Add a few references to Ada_05 that were missing.
27785 Update documentation on -gnatZ/-gnatL.
27786 Document limitation when using -m64 under Solaris.
27787 Change the "Name Casing" subsection of the pretty-printer section
27788 according to the changes in the dictionary processing.
27790 * gnat_rm.texi: Document the Ada_05 pragma.

28201 the formal subprogram.
28202 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28203 which is an unclean use of that field, we set the new field

28222 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28223 mark in function specification, in a context where the formals are
28224 visible and hide outer homographs.
28226 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28227 as the tagged type for the cases of abstract formal subprograms and
28228 renamings of those. Clean up spec comments.

28230 procedure", covering the case of a call to a formal abstract procedure
28231 that has statically tagged operands.
28232 (Check_Dispatching_Call): Check for the case of an actual given by
28233 a tag-indeterminate function call whose type is an ancestor of the
28234 containing call's associated tagged type. This situation can occur
28235 for inherited primitives with function defaults. In this case we
28236 use the tagged type's tag directly as the controlling argument for

28303 GNAT.OS_Lib.Set_Close_On_Exec.
28305 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
28306 the parent side as close-on-exec so that they are not inherited by the

28313 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28317 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28318 on the field if Pragma Component_Alignment (Storage_Unit).
28319 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28320 side-effects as if it were a constant; also make SAVE_EXPR to protect
28322 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28324 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.

28338 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28340 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28341 component of an array of arrays in an assignment context, and the
28342 aggregate has component associations that require sliding on
28343 assignment, force reanalysis of the aggregate to generate a temporary
28344 before the assignment.
28345 (Must_Slide): Make global to the package, for use in Gen_Assign.
28347 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28349 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28350 unchecked union with no inferable discriminants, return a

28353 (Expand_Record_Equality, Component_Equality): Handle properly the case
28354 where some subcomponent is an unchecked union whose generated equality
28355 code raises program error.

28363 Arnaud Charlet <charlet@adacore.com>
28365 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28366 address of the exception registration. The Win32 version of this
28367 routine calls __gnat_install_SEH_handler() to initialize the SEH
28368 (Structured Exception Handling) handler.
28369 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28370 SEH (Structured Exception Handling) now.
28371 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28372 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28373 preprocessor condition protecting the call to the extra eh setup
28374 subprogram, which is only available for the ppc target.
28375 (__gnat_clear_exception_count): replaced reference to
28376 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28378 * seh_init.c: New file.

28381 (GNATBIND_OBJS): Idem.
28383 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28384 routine takes a new parameter (a pointer to the exception registration
28385 for the SEH (Structured Exception Handling) support.
28387 * raise.h: (__gnat_install_SEH_handler): New prototype.
28388 Update copyright notice.
28390 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28391 record and initialize it by calling __gnat_install_SEH_handler.

28416 -shared-libgcc is now used by default on some systems (e.g. linux with
28418 Remove references to Makefile.prolog/generic, no longer used.
28420 2005-02-09 Vincent Celier <celier@adacore.com>
28422 * prj-makr.adb (Process_Directory): Put file name in canonical case
28423 before matching against the patterns.
28424 If gnatname has been invoked as <prefix>-gnatname
28425 then invoke the compiler as <prefix>-gcc, not just "gcc".
28427 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28429 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28430 with expansion disabled. The actual subtype is needed among other
28431 places when the selected component appears in the context of a loop
28432 bound, and denotes a packed array.
28433 (Operator_Check): Always use the first subtype in the
28434 error message, to avoid the appearance of internal base types.
28435 (Transform_Object_Operation): Copy each actual in full
28436 to the parameter associations of the constructed call, rather than
28437 using the shallow copy mechanism of New_Copy_List. This ensures that
28438 the chaining of named associations is done properly.
28439 (Complete_Object_Operation): Rewrite node, rather than
28440 replacing it, so that we can trace back to the original selected
28443 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28444 and calls that use object notation, if the called function is not
28445 declared in a withed unit, place the elaboration constraint on the
28446 unit in the context that makes the function accessible.
28447 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28448 imposes an elaboration constraint between two packages.
28450 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28452 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28453 views of a private type after handling its private dependents, to
28454 maintain proper stack discipline between entry and exit from the
28457 2005-02-09 Cyrille Comar <comar@adacore.com>

28477 * xr_tabls.ads: Add ??? comment for missing overall comment
28479 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28480 we now use by default.
28482 * xsnames.adb: Adjust end of file test to look for five space followed
28483 by '#' instead of six spaces. The format of xsnames.adb was modified
28484 in the last update.
28486 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28489 * clean.adb: Minor reformatting.
28491 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

28497 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28500 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28502 2005-02-09 Sergey Rybin <rybin@adacore.com>
28504 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28505 the difference between compact and incompact layout and add the record
28506 representation clause to the example illustrating different layouts.
28507 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28508 component clauses").
28510 2005-02-09 Florian Villoing <villoing@adacore.com>
28512 * gnat_ugn.texi: Fix typos.
28513 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28560 * exp_util.ads: Minor correction in comment.
28562 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28564 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28565 since this procedure is now too complex to be worth inlining.

28754 exception Bad_R_Line, instead of calling Fatal_Error, so that, when
28755 Ignore_Errors is True, default restrictions are set and scanning of the
28756 ALI file continues with the next line. Also, when Bad_R_Line is raised
28757 and Ignore_Errors is True, skip to the end of le line.

28815 is to check if two function signatures for a call-site and a callee are
28816 compatible enough for the call to be valid. The underlying purpose is
28817 to check if a call to a mapped builtin is using the right interface.
28818 The current code actually does not check antyhing - this a placeholder
28819 for future refinements.
28820 (gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle

28864 variable Dynamic_Async.
28865 (Build_Subprogram_Receiving_Stubs): Make PCS-specific

28870 structure of GARLIC and PolyORB RPC receivers.
28871 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28873 Simplify elaboration code for RCI packages.
28875 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

28987 Ada 2005 AI-368 restriction No_Obsolescent_Features.
28988 Preliminary rewriting of GNAT & libraries chapter in order to take

29215 (process_attributes): Clear DECL_COMMON again when a section attribute

29233 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29234 with an implicit dereference as its prefix, use

29237 prefix is generated, if appropriate.
29239 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29240 dereference is rewritten to an explicit one, generate a reference to
29241 the entity denoted by its prefix using the original prefix node, so
29242 the dereference can be properly recorded as a read of the denoted
29243 access value, if appropriate.
29245 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29246 emitting 'assigned but never read' warning on a variable on the basis

29359 prefix when operating under -gnatc. Necessary to avoid spurious
29360 'variable assigned but never read' warnings in that mode.
29361 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29362 is a non-overloaded implicit dereference, call the above subprogram to
29363 ensure proper recording of references.
29365 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29367 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29417 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29418 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29419 and -eit to -ept. Added qualifier

29428 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29429 internal implementation unit GNAT.Sockets.Thin,
29430 as their usage for sockets is non-portable (using the read and write
29431 functions from the system runtime library is fine on UNIX but won't
29432 work under Windows).

29485 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29487 * gigi.h (others_decl, all_others_decl): New decls representing the
29488 new Others_Value and All_Others_Value objects.
29489 (struct attrib): Rename "arg" component as "args", since GCC expects a
29490 list of arguments in there.
29492 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29493 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29496 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29497 others_decl and all_others_decl instead of hardcoded dummy addresses
29498 to represent "others" and "all others" choices, which is cleaner and
29499 more flexible with respect to the possible eh pointer encoding policies.
29501 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29502 (process_attributes): Account for the naming change of the "args"
29503 attribute list entry component.

29506 cumulating attributes for different entities into a single list.
29507 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29508 attributes for the current entity and propagate first subtype
29509 attributes to other subtypes.
29510 <E_Procedure>: Attribute arguments are attr->args and not
29511 attr->arg any more.
29512 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29513 argument provided, as this is what GCC expects. Use NULL_TREE instead

29551 (First_RCI_Subprogram_Id): Document this constant.
29552 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29554 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29555 replaced with calls to Get_Library_Unit_Name_String. Previously there
29556 were several instances of the same code in different locations in the
29557 compiler; this checkin completes the replacement of all of these
29558 instances with calls to a common subprogram.
29559 Minor reformatting.

29593 nodes are improperly shared.
29595 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29596 pragmas to Exp_Prag, which is more appropriate.
29597 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to

29604 Use new Make_String_Literal function with string.
29605 (Get_Stream_Convert_Pragma): New function, replaces the use of
29606 Get_Rep_Pragma, which had to be kludged to work in this case.
29608 * freeze.adb: Use new Has_Rep_Pragma function
29610 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29611 function with string.

29638 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29639 discriminant of a constrained subtype, analyze the copy of the
29640 corresponding constraint, because in some cases it may be only
29641 partially analyzed.

29644 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29645 handled controlled or secondary-stack expressions within the
29646 iteration_scheme of a loop.
29648 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29649 bounds that may contain functions calls, to prevent memory leaks when
29650 the bound contains a call to a function that uses the secondary stack.
29651 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29652 generate temporaries for loop bounds that might contain function calls
29653 that require secondary stack and/or finalization actions.

29656 selected component and the selector is overloadable (not just a
29657 function) treat as function call, Analyze_Call will disambiguate if

29660 selected component if expansion is disabled. The actual subtype is only
29661 needed for constraint checks.

29663 not permit objects to be declared of a stream type, or of a
29664 composite type containing a stream.

29667 No_Streams no longer prohibits with'ing this package.
29669 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29670 discriminants, but the parent base has unknown discriminants, there is
29671 no discriminant constraint to inherit. Such a discrepancy can arise
29672 when the actual for a formal type with unknown discriminants is a
29673 similar private type whose full view has discriminants.
29674 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29675 do not permit objects to be declared of a stream type, or of a
29676 composite type containing a stream.

29681 protected operations.
29683 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29684 generated name, it complicates decoding in gdb and hinders debugging

29730 procedure Protected_Single_Entry_Call.
29731 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29732 Detect_Blocking which is redundant with the check done within the

29774 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29777 * Makefile.in (darwin): Set soext to .dylib.
29779 2004-10-26 Vincent Celier <celier@gnat.com>
29780 Thomas Quinot <quinot@act-europe.fr>
29782 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29783 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29784 there is no use of GNAT.Sockets.Constants.
29785 Remove remaining pragma Import for C_Write
29786 Remove C_Read and C_Write from internal implementation unit
29787 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29788 the read and write functions from the system runtime library is fine
29789 on UNIX but won't work under Windows).
29791 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29792 (Check_Selector): Use C_Recv instead of C_Read.
29793 Selectors are the GNAT.Sockets abstraction to perform a select()
29794 call on a set of descriptors. To allow abortion of an ongoing
29795 select operation, some data is written to a dedicated socket that
29796 is always monitored.
29797 Under Windows, the write and read library functions cannot operate
29798 on sockets, so we need to use send and recv instead, which is portable
29799 across all supported platforms.
29801 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29802 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29803 (using the read and write functions from the system runtime library is
29804 fine on UNIX but won't work under Windows).
29806 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29808 * mlib-tgt-darwin.adb: New file.
29810 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29811 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29812 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29813 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29816 * Makefile.in: Add support for building shared libraries under Darwin.
29817 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29818 the low level EH init subprogram to be called from __gnat_initialize.
29820 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29821 indicates which options to pass to the archive indexer.
29823 * mlib-utl.adb: Add support for calling ranlib with additional
29824 options. This is needed for instance under Mac OS X.
29825 (Ranlib_Options): New global variable, used to store the potential
29826 options to pass to ranlib.
29827 (Ar): Use Ranlib_Options when spawning ranlib.
29828 (Initialize): Set the value of ranlib option.
29830 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29832 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29833 instead of 8K, to reflect the real potential needs for stack-checking
29836 2004-10-26 Pascal Obry <obry@gnat.com>
29838 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29840 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29841 Windows only the initial thread stack size can be set so it is good to
29842 start we a low stack size.
29843 The OS will adjust the size as needed.
29845 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29846 Nicolas Setton <setton@act-europe.fr>
29848 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29849 "__unix__" instead of "unix".
29850 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29851 sections were just mistakenly ignored. The former is
29852 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29853 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29854 of hpux. This prevents an unwanted definition of the symbol
29855 convert_addresses in adaint.o.
29857 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29859 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29860 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29862 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29864 * a-filico.ads, a-filico.adb: fix incorrect header.
29866 2004-10-26 Javier Miranda <miranda@gnat.com>
29868 * a-ststio.ads: Fix typo in identifier
29870 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29872 * sem_ch4.adb: Minor reformatting.
29874 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29876 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29877 enabled, check the result of unary and binary operations when the
29878 expression is the right-hand side of an assignment.
29880 2004-10-26 Vincent Celier <celier@gnat.com>
29882 * clean.adb (Delete): Do not output warnings when in quiet output and
29883 not in verbose mode.
29884 (Force_Deletions): New Boolean flag, defaulted to False
29885 (Delete): Only delete a file if it is writable, and when
29886 Force_Deletions is True.
29887 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29888 (Usage): Line for new switch -f
29889 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29892 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29894 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29895 JM type only if its size matches that of the wrapper. When a size is
29896 prescribed and the field is not aliased, remove the wrapper of a JM
29897 type only if the size is not greater than that of the packed array.
29898 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29901 2004-10-26 Geert Bosch <bosch@gnat.com>
29903 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29904 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29905 (Pred): Implement in terms of Succ.
29907 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29909 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29910 unchecked conversion is safe for in-place use if the expression of the
29911 conversion is safe.
29912 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29913 be expandable in place even if the aggregate does not come from source.
29914 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29915 designated object of an allocator in place, rather than building it
29916 first on the stack. The previous scheme forces a full copy of the array,
29917 and may be altogether unsusable if the size of the array is too large
29918 for stack allocation.
29920 2004-10-26 Robert Dewar <dewar@gnat.com>
29922 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29923 compares if the component is atomic.
29925 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29926 array assignment if the component type is atomic.
29928 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29929 Eric Botcazou <ebotcazou@act-europe.fr>
29931 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29932 is aliased and is a by_reference type, do not pass by copy.
29933 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29934 detect whether the call is in the right side of an assignment or
29935 the expression of an object declaration. Recurse on component
29936 association within aggregates.
29937 Call it in the condition that determines whether the temporary is
29938 necessary for correct stack-checking.
29940 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29942 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29943 RACW_Type, used in the PolyORB version.
29944 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29945 version and the GARLIC version.
29947 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29948 Rename RCI_Info to RCI_Locator for better consistency between the
29949 GARLIC and PolyORB versions of the distributed systems annex.
29950 (DSA_Implementation_Name): This enumeration lists the possible
29951 implementations of the Partition Communication Subsystem for the
29952 Distributed Systems Annex (DSA). The three available implementations
29953 are the dummy stub implementation (No_DSA), and two versions based on
29954 two different distribution runtime libraries: GARLIC and PolyORB. Both
29955 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29957 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29960 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29961 between the GARLIC and PolyORB versions of the distributed systems
29963 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29965 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29967 * gnat1drv.adb: Suppress calling the back end when
29968 Frontend_Layout_On_Target is true.
29970 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29972 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29973 Set_Read_Only): New subprograms.
29974 These new routines allow the user to set or unset the Owner execute
29975 and Owner write permission flags on a file.
29977 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29978 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29980 2004-10-26 Matthew Gingell <gingell@gnat.com>
29982 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29984 2004-10-26 Pascal Obry <obry@gnat.com>
29986 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29987 memory before the faulting page we properly test the process read
29988 access for this address using appropriate Win32 routine.
29989 (HPUX sections): guard with "__hpux__" instead of "hpux".
29991 2004-10-26 Robert Dewar <dewar@gnat.com>
29993 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29994 entry parameter if pragma Unreferenced set, since we do not properly
29995 handle the case of multiple parameters.
29997 2004-10-26 Vincent Celier <celier@gnat.com>
29999 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30000 (Ada_Objects_Path.Add): For a library project, add to the object path
30001 the library directory only if there is no object directory or if the
30002 library directory contains ALI files.
30003 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30005 2004-10-26 Vincent Celier <celier@gnat.com>
30007 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30008 extension of library projects.
30010 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30011 path defaults to ".:<prefix>/lib/gnat".
30012 (Parse): For an extending all project, allow direct import of a project
30013 that is virtually extended.
30015 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30016 the specified name is directly imported, return its ID. Otherwise, if
30017 an extension of this project is imported, return the ID of the
30020 2004-10-26 Robert Dewar <dewar@gnat.com>
30022 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30023 (Sub3): New procedure, used by Scaled_Divide
30024 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30025 correct more than one instance of failure to propagate carries
30027 (Double_Divide): Handle overflow case of largest negative number
30028 divided by minus one.
30030 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30031 the case of a quotient value out of range.
30034 2004-10-26 Robert Dewar <dewar@gnat.com>
30036 * s-bitops.adb (Bit_Eq): Remove redundant check.
30038 * s-bitops.ads: Minor comment updates
30039 Change some occurrences of Address to System.Address
30041 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30043 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30045 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30046 accessibility check to prefix that is a protected operation.
30048 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30050 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30051 empty, post message on stub.
30053 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30054 Javier Miranda <miranda@gnat.com>
30056 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30057 current instance appears within a unit that is directly in the context
30059 Used to determine whether the body of the instance should be analyzed
30060 immediately after its spec, to make its subprogram bodies available
30061 for front-end inlining.
30062 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30063 constraint is not allowed on the component type (AARM 12.5.3(3))
30065 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30067 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30068 'Storage_Pool): enhance, document & limit detection of non-sharable
30071 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30073 * s-pooglo.ads: Add more documentation now that this pool is properly
30076 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30078 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30079 or protected type with discriminants, do not constrain the
30080 corresponding record type if the subtype declaration has no
30081 discriminant constraints. This can be the case in source code, or in
30082 the subtype declaration created to rename an actual type within an
30085 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30087 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30088 different kind of stub (possibly wrong name for file), do not check
30090 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30091 includes call to some function that returns an unconstrained type, do
30094 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30096 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30097 appear in the code for the main unit. Dependencies among units in the
30098 context of the main unit are established when those other units are
30099 compiled. Otherwise spurious elaboration constraints can generate
30100 incorrect elaboration circularities.
30102 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30103 Ed Schonberg <schonberg@gnat.com>
30105 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30106 subprogram is called with a parameter that is not an object name. This
30107 situation arises for some cases of illegal code, which is diagnosed
30108 later, and in this case it is wrong to call Is_Aliased, as that might
30109 cause a compiler crash.
30110 (Explain_Limited_Type): Refine previous fix to include
30111 inherited components of derived types, to provide complete information.
30113 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30114 is the prival for a protected object.
30115 It is necessary to mark this entity as a variable, in addition to
30116 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30117 modified to avoid checking the Aliased flag on entities that are not
30118 objects. (Checking that flag for non-objects is erroneous and could
30119 lead to a compiler crash).
30121 2004-10-26 Robert Dewar <dewar@gnat.com>
30123 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30124 X_Frac = 0.5, then we know that the number X must be positive.
30125 (Succ): Remove the same redundant test, and also fix the primary test
30126 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30128 (Decompose): Add fuller comments to spec
30130 2004-10-26 Pascal Obry <obry@gnat.com>
30132 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30133 validity (process must have read access). Set to 0 in all other cases.
30134 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30135 violation on Win32.
30136 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30137 segmentation violation.
30139 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30141 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30142 whose type is a constructed subtype of an aliased object with an
30143 unconstrained nominal subtype, convert the actual to the constructed
30144 subtype before taking its address.
30146 2004-10-26 Vincent Celier <celier@gnat.com>
30148 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30149 (Is_Path_Name_Case_Sensitive): New function
30151 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30152 (Base_Name, Simple_Name, Current_Directory, Compose,
30153 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30156 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30157 Vasiliy Fofanov <fofanov@act-europe.fr>
30158 Vincent Celier <celier@gnat.com>
30160 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30161 "memory management issues" section and document some of the useful
30162 memory pools provided as part of the GNAT library.
30163 Remove "virtual" from declaration of A::method2 in
30164 the simple example of Ada/C++ mixed system.
30165 Library Projects may be virtually extended: their virtual extensions
30166 are not Library Projects.
30167 Added section on extending project hierarchies.
30169 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30171 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30173 (__gnat_portable_spawn): Remove const.
30175 * mingw32.h (MAXPATHLEN): Check for previous definition.
30177 2004-10-17 Matthias Klose <doko@debian.org>
30179 * gnatvsn.ads: Set gnat library version to 4.0.
30181 2004-10-05 Vincent Celier <celier@gnat.com>
30183 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30185 2004-10-04 Laurent Guerby <laurent@guerby.net>
30188 * Makefile.in: Define and use RANLIB_FLAGS.
30190 2004-10-04 Pascal Obry <obry@gnat.com>
30192 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30193 other x86 platforms).
30195 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30197 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30198 in general and triggers stack alignment adjustment for thread entry
30199 points on targets where this is necessary.
30201 2004-10-04 Bernard Banner <banner@gnat.com>
30204 * Makefile.in: Add section for powerpc linux
30205 Add variant i-vxwork-x86.ads
30207 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30209 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30211 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30212 table registration calls when need be. Ensures no reference to the crt
30213 ctors symbol are issued in the SJLJ case, which avoids possible
30214 undefined symbol errors in the case of modules to be statically linked
30217 2004-10-04 Javier Miranda <miranda@gnat.com>
30219 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30220 in-line the code corresponding to subprogram Analyze_Actuals. In
30221 addition, analyze the actuals only in case of subprogram call.
30223 2004-10-04 Ed Falis <falis@gnat.com>
30225 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30227 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30229 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30230 in the documentation.
30232 2004-10-04 Robert Dewar <dewar@gnat.com>
30234 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30236 (Analyze_Block_Statement): Add circuitry to detect following dead code
30237 (Check_Unreachable_Code): Handle case of block exit
30239 2004-10-04 Robert Dewar <dewar@gnat.com>
30241 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30242 (XMatchD): Avoid warning for Logic_Error call
30244 2004-10-04 Robert Dewar <dewar@gnat.com>
30246 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30247 consider expressions buried within a procedure actual to be an actual.
30248 This caused some blowups with uses of packed slices within a procedure
30251 2004-10-04 Robert Dewar <dewar@gnat.com>
30253 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30254 longer need to be initialized to zero.
30255 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30256 initialized to zero.
30258 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30259 considered valid, even if the representation is modular. That's correct
30260 now that we no longer initialize packed modular arrays to zero.
30262 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30263 suffixes. These are now documented as the only cases in which the
30264 debugger ignores outer records.
30265 Previously, the spec allowed arbitrary suffixes for this purpose.
30266 Change name of LJM to JM for packed array pad records
30267 Create separate section on packed array handling, and add a whole new
30268 set of comments to this section describing the situation with packed
30269 modular types and justification requirements depending on endianness.
30271 2004-10-04 Robert Dewar <dewar@gnat.com>

30286 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30287 Inline_Always when in Configurable_Run_Time mode.
30289 * sem_prag.adb (Process_Convention): If entity is an inherited
30290 subprogram, apply convention to parent subprogram if in same scope.
30291 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30292 when in Configurable_Run_Time mode.
30294 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30296 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30297 class_wide type after component list has been inherited.

30301 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30302 Denotes_Previous_Actual, to handle properly the case of a private
30303 actual that is also the component type of a subsequent array actual.
30304 The visibility status of the first actual is not affected when the
30305 second is installed.
30306 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30307 make fully recursive the treatment of formals of packages declared
30309 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30310 the above on exit from an instantiation.
30311 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30312 current instantiation which is now complete.
30313 (Analyze_Package_Instantiation): No instantiated body is needed if the
30314 main unit is generic. Efficient, and avoid anomalies when a instance
30315 appears in a package accessed through rtsfind.
30317 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30319 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30320 do not generate a declaration for a temporary if the call is part of a
30321 library-level instantiation.
30323 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30325 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30326 searching for a limited component to flag.
30328 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30329 expansion of Input, to account for the fact that the implicit call
30330 generated by the attribute reference must freeze the user-defined
30331 stream subprogram. This is only relevant to 'Input, because it can
30332 appear in an object declaration, prior to the body of the subprogram.
30334 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30335 expansion can proceed and further errors uncovered.
30336 (Minor clean up): Fix cases of using | instead of \ for continuation
30339 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30341 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30343 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30344 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30345 Use gcc_assert and gcc_unreachable.
30347 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30348 specified alignment before validating size.
30349 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30350 stripped-down declaration for the type of the inner field when making
30353 * utils.c (finish_record_type): Do not compute the size in units
30354 incrementally. Instead compute it once for the rep clause case.
30355 Use gcc_assert and gcc_unreachable.
30357 2004-10-04 Vincent Celier <celier@gnat.com>
30359 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30361 (Is_Valid_Path_Name): Take '/' as a directory separator.
30363 2004-10-04 Vincent Celier <celier@gnat.com>
30365 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30366 (Extended_Project) only if Extended_Project is defined, to avoid
30368 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30370 (Parse_Single_Project): Ditto.
30372 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30373 Add_To_Project_Path for virtual projects.
30375 2004-10-04 Vincent Celier <celier@gnat.com>
30377 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30381 parameter Options_2.
30383 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30384 Build_Dynamic_Library with an empty Options_2.
30386 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30389 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30390 directory separator, if any.
30391 (Gprmake): Do not allow mains on the command line for library projects.
30392 Do not attempt to link when the project is a library project.
30393 (Library_Opts): New table to store Library_Options.
30394 (Build_Library): If Library_Options is specified, pass these options
30395 when building a shared library.

30419 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30420 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30421 used to signal whether the compiler creates the required stacks and
30422 descriptors for the different tasks (when True) or it is done by the
30423 underlying operating system at run time (when False).
30424 It is initially set to False in all targets.
30426 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30427 if it is supported by the target.
30428 (Make_Task_Create_Call): Pass the stack address if it has been
30429 previously created. Otherwise pass a Null_Address.

30434 statically allocated task stacks.
30436 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30437 Stack_Address argument.
30438 Check that its value is equal to Null_Address because this target does
30439 not support the static stack allocation.
30441 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30443 * usage.adb: Change "pragma inline" to "pragma Inline" in information

30448 * exp_dist.adb: Split declaration of asynchronous flag out of
30449 Add_RACW_Read_Attribute.
30450 Minor reformatting for better alignment with PolyORB version.
30451 Store the entity for the asynchronous flag of an RACW, rather than the
30452 expression, in the asynchronous flags table. This will allow this flag
30453 to be used in other subprograms beside Add_RACW_Read_Attribute.
30455 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30457 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30461 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30462 sockets constant MSG_NOSIGNAL (Linux-specific).
30463 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30464 all Send operations.
30465 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30466 from trigerring SIGPIPE.
30467 Rename components to avoid clash with Ada 2005 possible reserved
30469 (Check_Selector): When the select system call returns with an error
30470 condition, propagate Socket_Error to the caller.
30472 2004-10-01 Jan Hubicka <jh@suse.cz>
30474 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.

30482 Change "pragma inline" to "pragma Inline" in information and error
30484 Minor reformatting.
30486 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30487 right way of doing things after all.

30493 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30494 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30495 ensures proper handling of types with rep clauses, which might have
30496 their TYPE_SIZE set already.
30498 2004-09-21 Robert Dewar <dewar@gnat.com>
30500 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30501 packed array types in both little- and big-endian cases. This change
30502 ensures that we no longer count on the unused bits being initialized
30503 for such types (and in particular ensures that equality testing will
30504 only read the relevant bits).
30505 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30506 These changes mean that we no longer need to initialize small packed
30508 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30509 optimization to an LJM field as to its parent field.
30511 * ada-tree.h, trans.c, utils.c, utils2.c:

30514 2004-09-20 Jan Hubicka <jh@suse.cz>
30516 * utils.c (gnat_finalize): Remove.
30517 (end_subprog_body): Directly call cgraph_finalize_function;
30518 do not lower the nested functions.
30520 2004-09-20 Robert Dewar <dewar@gnat.com>
30523 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30524 if an address clause is present, since that means that the Import
30527 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30529 * 5tsystem.ads: Removed, no longer used.

30553 an existing directory.
30554 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30555 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30556 Convert the result to File_Size.
30558 * prj.ads: (Project_Error): New exception
30560 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30561 Prj.Com, not from Osint.
30562 (Attrs, Package_Attributes): Tables moved to private part of spec
30563 (Add_Attribute, Add_Unknown_Package): Moved to new child package

30566 Prj.Project_Error after call to Fail.
30567 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30568 Fail. Check that package name is not already in use.
30570 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30571 used by tools, not only by the project manager, and to indicate that
30572 exception Prj.Prj_Error may be raised in case of problem.
30573 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30575 (Attrs, Package_Attributes): Table instantiations moved from the body to

30693 This procedure does not insert a call for raising the exception because
30694 that is currently done by the run time.
30696 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30698 * init.c: Add the global variable __gl_detect_blocking that indicates

30708 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30709 DB is found in the ali file. Any unit compiled with pragma
30710 Detect_Blocking active forces its effect in the whole partition.

30748 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30749 Asynchrronous that applies to a remote access-to-subprogram type, mark
30750 the underlying RACW type as asynchronous.

30765 a component declaration must remain attached at that point in the
30766 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30767 It is therefore necessary to take a copy of the expression when building
30768 the corresponding assignment statement in the init proc.
30769 As a side effect, in the case of a derived record type, we now see the
30770 original expression, without any rewriting that could have occurred
30771 during expansion of the ancestor type's init proc, and we do not need
30772 to go back to Original_Node.

30782 subprogram. The proxy object is used as the designated object
30783 for RAS values on the same partition (unless All_Calls_Remote applies).
30784 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30785 System.Partition_Interface.Get_Unique_Remote_Pointer.
30786 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30787 Renamed from Add_RAS_*_Attribute.

30790 New implementation of expansion for remote access-to-subprogram types,
30791 based on the RACW infrastructure.
30793 * exp_dist.ads (Copy_Specification): Update comment to note that this
30794 function can copy the specification from either a subprogram
30795 specification or an access-to-subprogram type definition.

30804 add a polling call if the subprogram is to be inlined by the back-end,
30805 to avoid repeated calls with multiple inlinings.
30807 * checks.adb (Apply_Alignment_Check): If the expression in the address
30808 clause is a call whose name is not a static entity (e.g. a dispatching
30809 call), treat as dynamic.

30975 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30976 target names rewrite to fix regressions with recent version of

31030 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31031 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31032 option and not mdll anymore. Update comment.
31034 2004-08-16 Pascal Obry <obry@gnat.com>
31036 * bld.adb (Put_Include_Project): Properly handle directory separators

31054 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31055 for a global aliased object with a variable size and an unconstrained
31056 nominal subtype, pretend there is no initializer if the one we have is
31057 incomplete, and avoid referencing an inexistant component in there. The
31058 part we have will be rebuilt anyway and the reference may confuse

31081 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
31082 unit, this is an attempt to inline a construct that is not available in
31083 the current restricted mode, so abort rather than trying to continue.
31085 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31086 discriminants that rename those of the parent, recover names of
31087 original discriminants for the constraint on the full view of the
31089 (Complete_Private_Subtype): Do not create a subtype declaration if the
31090 subtype is an itype.
31092 * gnat_rm.texi: Added section on implementation of discriminated

31118 returning C.int, to avoid using a derived boolean type.
31120 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31148 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
31149 ignore overflows on low and high bounds of an index to also account for
31150 differences in signedness between sizetype and gnu_index_subtype.
31151 These are as legitimate as the ones caused by a lower TYPE_PRECISION
31154 2004-08-09 Robert Dewar <dewar@gnat.com>

31251 the parent initialization procedure for derived Unchecked_Unions.
31252 Instead, derived Unchecked_Unions build their own initialization
31254 (Build_Variant_Record_Equality): Implement Unchecked_Union equality.
31255 Check the body of the subprogram for details.
31256 (Freeze_Record_Type): Prevent the inheritance of discriminant checking

31818 for a renaming, stabilize the initialization expression if we are at a

31877 when Keep_Temporary_Files is False.
31878 (GNATCmd): When not on VMS, and the GNAT driver has been invoked with
31879 directory information, add the directory in front of the path.
31880 When not on VMS, handle new switch -dn before the command to set

33074 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33778 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33779 overriding, use the operation of the parent unconditionally.
33781 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33782 operation when either operand is a literal, to avoid further
33785 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

35068 complete assignment subtree which is now unnecessary, as the expansion
35069 of inlined call has been improved to preserve a consistent assignment

35332 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35333 executable name when not initialized. Otherwise, use its current value.
35335 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35336 initialize it to another executable name than the current one. This
35337 allows to configure paths for an executable name (gnatmake) different
35338 from the current one (gnatdist).
35340 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35342 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35343 current unit cannot be inlined if it appears in the body of a withed
35344 unit, to avoid order of elaboration problems in gigi.
35346 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35347 information for protected (wrapper) operation as well, to simplify gdb
35350 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35351 protected body, indicate that the entity for the generated spec comes
35352 from source, to ensure that references are properly generated for it.

35387 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35389 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35390 attribute reference does not denote a subtype, it can be any
35391 expression that has a classwide type, potentially after an implicit
35392 dereference. In particular, the prefix can be a view conversion for
35393 a classwide type (for which Is_Object_Reference holds), but it can
35394 also be a value conversion for an access-to-classwide type. In the
35395 latter case, there is an implicit dereference, and the original node
35396 for the prefix does not verify Is_Object_Reference.
35398 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35399 conversion of a discriminant-dependent component of a mutable object
35402 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35404 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35405 inherited, has convention C, and has unconstrained array parameters,

35423 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35424 value expressions to ensure that calls within a component definition
35425 will be checked (since those are evaluated during the record type's

35477 declaration for a child subprogram body that acts as a spec, indicate
35478 that the entity in the declaration needs debugging information.
35480 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35481 full view if the subtype is created for a constrained record component;
35482 gigi has enough information to construct the record, and there is no
35483 place in the tree for the declaration.
35485 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35486 serial number for the dummy body that is built for analysis, to avoid

35524 Minor reformatting.
35526 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35528 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35529 as regular exception objects and not as mere integers representing the
35530 condition code. The latter approach required some dynamics to mask off
35531 severity bits, which did not fit well into the GCC table based model.
35532 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35533 exception data objects. We don't it and it would conflict with the other
35534 external symbol we have to generate for such exceptions.
35536 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35537 the special code for VMS exceptions, since these are now represented
35538 as regular exceptions objects.

35581 When needed (stack checking) the stack size is retrieved
35582 from the VxWorks kernel.
35584 * Makefile.in: Flag -nostdinc is required when building the run time
35585 for avoiding looking for files in the base compiler.
35586 Add the VxWorks specific version of the package body for
35587 System.Stack_checking.Operations (5zstchop.adb).
35589 * Make-lang.in: Add the object file for
35590 System.Stack_Checking.Operations.

35615 the procedures Add_To_Path_File.
35616 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35617 making sure that each directory is present only once and, for object
35618 dirs, when a directory already present is added, the duplicate is
35619 removed and the directory is always put as the last in the table.
35620 Write the path files at the end of these accumulations.

35832 explicit dereference.
35833 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35834 of non-packed slices, since the dereference action generated by

35837 analyze and resolve the rewritten explicit dereference so it is seen
35839 (Insert_Dereference_Action): This procedure is now called only for the

36678 restricted profile.
36680 * sem_ch9.adb (Analyze_Requeue): Check the new restriction
36681 No_Requeue_Statements.
36683 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)

36685 kept for backward compatibility.
36687 2004-02-02 Ed Schonberg <schonberg@gnat.com>
36689 * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,

36716 * utils.c (create_field_decl): Augment the head comment about bitfield
36717 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
36718 here, because the former is not accurate enough at this point.
36719 Let finish_record_type decide instead.
36720 Don't make a bitfield if the field is to be addressable.
36721 Always set a size for the field if the record is packed, to ensure the
36722 checks for bitfield creation are triggered.
36723 (finish_record_type): During last pass over the fields, clear
36724 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
36725 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
36726 from DECL_BIT_FIELD.

37183 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37184 N_String_Literal node always references an E_String_Literal_Subtype
37185 entity. This may not be true in the future.
37186 (Possible_Bit_Aligned_Component): Move processing of
37187 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37189 * exp_ch6.adb (Expand_Thread_Body): Pick up
37190 Default_Secondary_Stack_Size as variable so that we get value modified
37191 by possible -Dnnn binder parameter.
37193 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37194 (Type_May_Have_Bit_Aligned_Components): New function.

37234 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37235 ineffective elaborate all pragmas on non-visible packages (this
37236 happened when a renamed subprogram was called). Now the elaborate all
37237 always goes on the package containing the renaming rather than the one
37238 containing the renamed subprogram.
37240 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37241 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37496 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37497 bounds of a loop, create a separate block in order to generate proper
37498 cleanup actions to prevent memory leaks.
37500 * sem_res.adb (Resolve_Call): After a call to
37501 Establish_Transient_Scope, the call may be rewritten and relocated, in

37520 2003-12-08 Robert Dewar <dewar@gnat.com>
37522 * 7sintman.adb: Minor reformatting
37524 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37525 standard linker options to get standard libraries linked. We now plan
37526 to provide dummy versions of these libraries to match the appropriate
37527 configurable run-time (e.g. if a library is not needed at all, provide
37528 a dummy empty library).
37530 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37531 options (-L parameters and standard libraries). What we plan to do is
37532 to provide dummy libraries where the libraries are not required.
37534 * gnatbind.adb: Minor comment improvement
37536 2003-12-08 Javier Miranda <miranda@gnat.com>
37538 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

37546 of aggregate with default initialized components.
37547 (Has_Default_Init_Comps): Improve implementation to recursively check
37548 all the present expressions.
37550 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37551 to indicate that the initialization call corresponds to a
37552 default-initialized component of an aggregate.
37553 In case of default initialized aggregate with tasks this parameter is
37554 used to generate a null string (this is just a workaround that must be
37555 improved later). In case of discriminants, this parameter is used to
37556 generate a selected component node that gives access to the discriminant
37559 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37560 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37561 allocated aggregates with default-initialized components.
37563 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37564 the box notation is used in positional aggregates.

37606 Process nodes N_Comment.
37608 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37609 without comments and there are some comments, set the flag
37610 Unkept_Comments to True.
37611 (Scan): If there are comments, set the flag Unkept_Comments to True and
37612 clear the comments.
37613 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37614 (Next_End_Nodes: New table

37642 Comment_Id and set Token to Tok_Comment when scanning a comment.
37643 (Set_Comment_As_Token): New procedure
37645 * sinput-p.adb: Update Copyright notice
37646 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

37652 Correct typo in comment
37653 (Resolve_Aggregate): In case of array aggregates set the estimated
37654 type of the aggregate before calling resolve. This is needed to know
37655 the name of the corresponding IP in case of limited array aggregates.

37679 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37680 they are automatically generated by Make-lang.in and cause nothing but
37681 maintenance troubles.

37702 unwind past it. Update the copyright notice.
37704 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37706 * a-elchha.ads: New file.

39160 Remove the test against being in No_Run_Time_Mode before generating a
39161 call to Register_Tag. It is redundant with the test against the
39162 availability of the function Register_Tag.

41105 used elsewhere. This fixes the problem of the back end not
41106 realizing we were clever enough to see that this was

41109 (Expr_Rep_Val): Remove call to Constant_Array_Ref
41111 (Constant_Array_Ref): Deal with string literals (patch
41112 suggested by Zack Weinberg on the gcc list)

41365 rule which was mandated by code generation issues.
41367 * gnat-style.texi (header): Add @dircategory, @direntry.
41368 (title page): Remove date.
41369 (general) Add @./@: where approriate, and two spaces after the
41370 full stop at the end of a sentence. Use @samp markup when
41371 referring concrete lexical entities (keywords, attribute names
41372 etc.), and @syntax for ARM grammar elements. Use @r for English

41387 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41388 function approach did not work well because of a side effect (the
41389 function call could reallocate the table which was being indexed
41390 using its result). Fixes ada/4851.
41392 2001-12-19 Robert Dewar <dewar@gnat.com>

41426 2001-12-19 Olivier Hainque <hainque@gnat.com>
41428 * raise.c (__gnat_eh_personality): Exception handling personality
41429 routine for Ada. Still in rough state, inspired from the C++ version
41430 and still containing a bunch of debugging artifacts.
41431 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
41432 inspired from the C++ library.
41434 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
41435 exception handling integration.

41446 2001-12-19 Robert Dewar <dewar@gnat.com>
41448 * a-ngelfu.adb: Remove ??? comment for inappropriate Inline_Always
41449 Add 2001 to copyright date
41451 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41452 need to force universal inlining for these cases.
41454 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41456 * s-taprob.adb: Minor clean ups so that this unit can be used in
41459 * exp_ch7.adb: Allow use of secondary stack in HI mode.
41460 Disallow it when pragma Restrictions (No_Secondary_Stack) is specified.
41462 2001-12-19 Vincent Celier <celier@gnat.com>
41464 * prj-tree.ads (Project_Node_Record): Add comments for components
41465 Pkg_Id and Case_Insensitive.

41481 * sem_res.adb (Resolve_Selected_Component): do not generate a
41482 discriminant check if the selected component is a component of
41483 the argument of an initialization procedure.
41485 * trans.c (tree_transform, case of arithmetic operators): If result
41486 type is private, the gnu_type is the base type of the full view,
41487 given that the full view itself may be a subtype.

41757 2001-12-17 Laurent Pautet <pautet@gnat.com>
41760 Fix comment of Shutdown_Socket and Close_Socket. These functions
41761 should not fail silently because if they are called twice, this
41762 probably means that there is a race condition in the user program.
41763 Anyway, this behaviour is consistent with the rest of this unit.
41764 When an error occurs, an exception is raised with the error message
41765 as exception message.

43094 (GNATMAKE_RTL_OBJS): add g-crc32.o
43097 (CRC_Match): new function.
43098 (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
43099 instead of the previous simple checksum algorithm.
43100 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43101 (Set_Source_Table): idem.
43104 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43105 instead of simple checksum.
43106 (CRC_Match): new function.
43107 (CRC_Error): new constant.
43109 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43110 a CRC now and not a simple checksum. A CRC uses lower-case hex
43111 letters, fixes ambiguity in parsing.
43113 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43114 is what this variable will store.
43116 * bcheck.adb: Change reference to chechsum in comments by CRC.
43117 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43118 rename All_Checksum_Match to All_CRC_Match. Change due to API
43119 renaming since now GNAT does not use a simple checksum but a
43120 CRC using GNAT.CRC32.
43122 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43123 now and not anymore a simple checksum.
43125 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43128 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43131 (Restore_Scan_State): rename Checksum to CRC.
43132 (Save_Scan_State): idem.
43136 (Checksum): rename to CRC.
43137 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43139 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43140 GNAT.CRC32). Update copyright notice.
43142 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43143 GNAT.CRC32). Update copyright notice.
43146 (Accumulate_Checksum): removed.
43147 (Update): new procedure. Add a wide-character into the CRC.
43150 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43151 (Load_File): fix initialization of S (change Source_Checksum to
43154 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43155 Source_CRC in S initialization.
43157 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43159 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43160 Update comments for the CRC.
43162 * types.adb (Hex): Use lowercase for the letter part.
43164 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43165 for a word. This is currently used only for CRC. In previous version,
43166 the checksum was using a representation with all letter being
43167 upper-case. With the new implementation (using CRC) we do not remove
43168 the 32th bit of the CRC, so we can have an upper-case starting letter
43169 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43170 It is ambigous since the CRC was optional and could be followed by
43171 options like EB, EE. So now this routines uses lower-case letter for
43172 the hexadecimal representation. Strange enough only lower case letters
43173 where checked in Scan_ALI (even if this was not a possible case).
43175 * gnatvsn.ads (Library_Version): changed to 3.15a.
43177 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43180 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43183 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43184 Add 2001 to copyright notice
43185 (Accumulate_Checksum): Modify to use System.CRC32.
43187 * ali-util.ads: Redo changes of previous revision to continue to use
43188 the word Checksum. Add 2001 to copyright notice.
