2305 result type is class-wide and inherently limited, and the expression

2307 more efficient handling of returns of build-in-place aggregates (avoids
2308 conversions of the class-wide return object to the specific type on
2309 component assignments).
2310
2311 * sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error
2312 about a type mismatch for a class-wide function with a return object
2313 having a specific type when the object declaration doesn't come from

8706 (Check_Version_And_Help): Change Check_Version_And_Help to be generic,
8707 with a parameter "procedure Usage", instead of passing a pointer to a

8710 unnest it).
8711
8712 * g-comlin.adb (For_Each_Simple_Switch): Change For_Each_Simple_Switch
8713 to be generic, with a parameter "procedure Callback (...)", instead of

8756
8757 * exp_aggr.adb (Build_Record_Aggr_Code): If there is an aggregate for a
8758 limited ancestor part, initialize controllers of enclosing record
8759 before expanding ancestor aggregate.

8761 code to call Initialize if the component is controlled, and explicit
8762 assignment of null if the component is an access type.
8763
8764 Handle properly aggregates for limited types that appear in object
8765 declarations when the aggregate contains controlled values such as
8766 protected types.

8781 type of formal Renamed_Eq to Entity_Id (instead of Node_Id).
8782 (Make_Predefined_Primitive_Specs): Spec of "=" needed if the parent is
8783 an interface type. In case of limited interfaces we now declare all the
8784 predefined primitives associated with synchronized interfaces as
8785 abstract.
8786 (Predef_Spec_Or_Body): For interface types generate abstract subprogram
8787 declarations.
8788 (Predefined_Primitive_Bodies): Add body of "=" if the parent of the

8840 and Ada 2005 models of requeue.
8841 (Null_Statements): Still connsider do-end block null if it contains
8842 Unreferenced and Warnings pragmas.

8891 literal is a subtype with non-static constraints, use the base type of
8892 the context as the base of the string subtype, to prevent type
8893 mismatches in gigi.
8894 (Resolve_Actuals): If the actual is an entity name, generate a
8895 reference before the actual is resolved and expanded, to prevent
8896 spurious warnings on formals of enclosing protected operations.

8921
8922 * layout.adb (Resolve_Attribute, case 'Access): If designated type of
8923 context is a limited view, use non-limited view when available. If the

8925 requirements in 3.10.2 (27).
8926 (Layout_Type): For an access type whose designated type is a limited
8927 view, examine its declaration to determine if it is an unconstrained

8939 in 3.10.2 (27).
8940 (Layout_Type): For an access type whose designated type is a limited
8941 view, examine its declaration to determine if it is an unconstrained
8942 array, and size the access type accordingly.

9000 representation clause, favor the message that complains about
9001 duplication rather than inconsistency.
9002 Update comments.
9003 (Record_Representation_Clause): Do not warn on missing component
9004 clauses for inherited components of a type extension.
9005 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
9006 an overloadable item if it is a pragma that can apply to multiple
9007 overloadable entities (e.g. Inline) because a pragma cannot be on
9008 more than one chain at a time.
9009 (Validate_Unchecked_Conversion): Add code to warn on unchecked
9010 conversion where one of the operands is Ada.Calendar.Time.
9011 (Analyze_Attribute_Definition_Clause): Fix typo in error message.

9022 (Hash): Move instantiation of System.HTable.Hash from spec to body
9023 (prj-nmsc.adb): Optimize calls to Name_Find when on case sensitive
9024 systems, since we do not need to recompute the Name_Id for the canonical
9025 file name.
9026 (Body_Suffix_Id_Of, Spec_Suffix_Id_Of): new version that takes a name_id
9027 as a parameter. This parameter is in fact always "ada" in all calls, and
9028 we were doing 160560 extra calls to Name_Find to convert it to Name_Ada
9029 while loading a project with 40000 files
9030
9031 * prj-attr.adb: Fix name of attribute Dependency_Driver

9138 subprogram body that acts as its own spec may not have a non-private
9139 WITH clause on a private sibling.
9140 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
9141 child unit is a renaming, create an implicit with_clause on that
9142 parent, and not on the unit it renames, to prevent visibility errors
9143 in the current unit.

9146
9147 * sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram
9148 renaming declaration, use the Slocs of the formal parameters from the

9150 entities in the renaming declaration.
9151 (Analyze_Formal_Type_Declaration): Change the placement of the error
9152 message concerning illegal known discriminants. It is now posted on the
9153 type rather than on the first discriminant. This change ensures early
9154 error report.
9155 (Freeze_Subprogram_Body): If the generic subprogram is nested within
9156 the package body that contains the instance, do not generate an

9178
9179 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid

9184 flag.
9185 (Derive_Subprograms): Handle derivations of predefined primitives

9189 of Related_Interface to Related_Type.
9190 (Record_Type_Declaration): Minor reordering of calls to decorate the

9202 (Find_Primitive_Operation): Handle case of class-wide types.
9203 (Analyze_Overloaded_Selected_Component): If type of prefix is
9204 class-wide, use visible components of base type.
9205 (Resolve_Selected_Component): Ditto.
9206 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
9207 formal of a generic subprogram. find candidate interpretations by
9208 scanning the list of generic formal declarations.:

9210 type from a limited_with_clause, and the full view is available, use it
9211 for subsequent semantic checks.
9212 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
9213 (Find_Primitive_Operation): New function.
9214 (Analyze_Overloaded_Selected_Component): insert explicit dereference
9215 only once if several interpretations of the prefix yield an access type.
9216 (Try_Object_Operation): Code and comment cleanup.
9217 (Analyze_Selected_Component): Reorder local variables. Minot comment and

9232 (Analyze_Renamed_Primitive_Operation): new procedure to determine the
9233 operation denoted by a selected component.

9239 Gary Dismukes <dismukes@adacore.com>
9240
9241 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
9242 requeue statement is dispatching. Do not emit an error when the name is
9243 not an entry and the context is a dispatching select. Add code to
9244 perform subtype conformance between the formals of the current entry
9245 and those of the target interface primitive.
9246 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9247 Timed_Entry_Call): Analyze the triggering statement as the first step of
9248 the processing. If this is a dispatching select, postpone the analysis
9249 of all select statements until the Expander transforms the select. This
9250 approach avoids generating duplicate identifiers after the Expander has
9251 replicated some of the select statements. In case the Expander is
9252 disabled, perform regular analysis.
9253 (Check_Triggering_Statement): New routine.
9254 (Analyze_Requeue): Exclude any interpretations that are not entries when
9255 checking overloaded names in a requeue. Also test type conformance for
9256 matching interpretations rather than requiring subtype conformance at
9257 that point to conform with the RM's resolution rule for requeues.
9258
92592007-12-13 Ed Schonberg <schonberg@adacore.com>
9260
9261 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
9262 inherited operation is a defaulted tag-indeterminate call, and there is
9263 a statically tagged actual, use the static tag as a controlling actual
9264 for the defaulted actual.
9265

9284 (Collect_Abstract_Interfaces): Update occurrences of Related_Interface
9285 to Related_Type.
9286 (Collect_Interfaces_Info): Minor update to handle the two secondary
9287 dispatch tables. Update occurrence of Related_Interface to Related_Type.

9290 initialize a component of a type with preelaborable initialization.
9291 This includes the case of a discriminal used in such a context.

9293 latest Ada 2005 rules about renaming and 'Access of
9294 discriminant-dependent components.

9296 subprograms (e.g. case of a package body).
9297 (Find_Parameter_Type): Factor routine from several other compiler files.

10345 avoids calling Time_Of and Split, thus making it more efficent.
10346 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10347

103512007-09-26 Emmanuel Briot <briot@adacore.com>
10352
10353 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10354 Command_Line): New types
10355 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10356 support for defining how switches can be grouped on a command line (as
10357 is the case for -gnatw... for GNAT), and how simple switches can be
10358 used as aliases for more complex switches (-gnatwa is same as
10359 -gnatwbcef...)
10360 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10361 (Start, Current_*): New subprograms
10362 Added support for parsing an array of strings in addition to the real
10363 command line.
10364 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10365 be moved from the body to the private part of the spec.
10366 (*): All subprograms now have an extra parameter with default value to
10367 specify which parser should be used. For backward compatibility, it
10368 defaults to parsing the command line of the application. They were also
10369 modified to properly handle cases where each of the argument does not
10370 start at index 1 (which is always true for Ada.Command_Line, but not
10371 when processing any Argument_List).
10372 (Free): New subprogram
10373 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10374 Argument): New subprograms
10375 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10376 special characters like ':', '=',... are now handled in a single place,
10377 which makes the code more extensible eventually.
10378 (Getopt, Full_Switch): When the switch was returned as part of the
10379 special character '*', make sure it is prepended by the switch character
10380 ('-' in general), so that the application knows whether "foo" or "-foo"
10381 was specified on the command line.
10382
103832007-09-26 Florian Villoing <villoing@adacore.com>

10386 recursively, make sure that if an exception is raised during the
10387 processing, the current working directory is reset to its initial
10388 value before propagating the exception.

10393 a main program to bind, the first ALI is expected to contain the main
10394 subprogram and the names of the binder generated files will be derived
10395 from the first ALI file name.

10776 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10777 create an abstract subprogram in the case of 'Input. For 'Output we now
10778 create a real spec/body when the type is abstract, since it can
10779 potentially be called.
10780 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10781 body for 'Output when the type is abstract (only the creation of the
10782 body for 'Input is excluded when the type is abstract).
10783 (Stream_Operation_OK): Add an additional condition in the return
10784 statement, so that False will be returned for TTS_Stream_Input if the
10785 associated tagged type is an abstract extension. Add comments for
10786 return statement.
10787 (Expand_N_Object_Declaration): For the case of a shared passive
10788 variable, insert init proc call only after the shared variable
10789 procedures have been processed, because the IP call needs to undergo
10790 shared passive variable reference expansion, which requires these
10791 procedures to be available (and elaborated).

10803 type, retrieve its value from the aggregate itself, where it must have

10805
10806 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10807 to remove other spurious ambiguities on arithmetic operations involving
10808 literals and addresses, on systems where Address is a visible integer
10809 type, when the operator is called in functional notation.
10810 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10811 is legal when the types match, even if the operation is currently
10812 hidden.

11130
11131 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
11132 ancestor part given by an aggregate to test for an unchecked conversion,
11133 since this can occur in some cases when the ancestor part is a function
11134 call, and we don't want to fall into the recursive call to this
11135 procedure in that case.
11136
11137 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
11138 stream attributes on limited types to account for user-specified
11139 attributes as well as whether Input (resp. Output) becomes available
11140 due to Read (resp. Write) being available for the type. Change Boolean
11141 variable to the more accurate name
11142 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
11143 double-"not" predicate at beginning of return statement to more
11144 understandable form.
11145
11146 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
11147 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
11148 in a block statement and use that as the first statement of the
11149 expanded return rather than incorrectly using the handled sequence as
11150 the first statement.
11151
11152 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
11153 operation, generate an explicit freeze node for it rather than

11155 elaboration for anonymous subtypes in the signature of the subprograms.
11156 (Build_In_Place_Formal): Move assertion to beginning of loop.
11157 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

11167 components that are access type with an allocator as default value: add
11168 missing support to the use of qualified expressions of the
11169 allocator (which also cause freezing of the designated type!)
11170 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
11171 dispatching operation, since extra formals may be needed by calls to
11172 build-in-place functions (such as stream 'Input).
11173
11174 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
11175 formals for 'Constrained and accessibility level in the case of a
11176 predefined dispatching operation.

11189 is not really required and can introduce regression with the debugger.

11205 parameter Including_Non_Switch, defaulted to True. When
11206 Including_Non_Switch is False, options that are not switches and
11207 appear as relative path are not converted to absolute paths.

11222 from the immediate ancestor of Main_Unit_Entity.
11223 (Install_Limited_Withed_Unit): Do not install the limited view of

11260 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11261 the statement which is being resolved comes from a predefined library
11262 unit, all non-predefined library interpretations are skipped.
11263 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11264 but the "&" is user defined, give an error, because the folding would
11265 be wrong.

11327 needed for access to concurrent record types generated by the expander.
11328 (Generate_Range_Check): When generating a temporary to capture the

11330 temporary before rewriting the node, so that the type is always
11331 properly placed for back-end use.
11332 (Apply_Float_Conversion_Check): Handle case where the conversion is

11351 parameters when deciding whether to apply a run-time accessibility
11352 check.
11353 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11354 aggregate code before allocator, and ahead of declaration for
11355 temporary, to prevent access before elaboration when the allocator is
11356 an actual for an access parameter.
11357 (Expand_N_Type_Conversion): On an access type conversion involving an
11358 access parameter, do not apply an accessibility check when the
11359 operand's original node was an attribute other than 'Access. We now
11360 create access conversions for the expansion of 'Unchecked_Access and
11361 'Unrestricted_Access in certain cases and clearly accessibility should
11362 not be checked for those.
11363
11364 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11365 includes a type conversion of a packed component that has been expanded,
11366 recover the original expression for the object, and use this expression
11367 in the post-call assignment statement, so that the assignment is made
11368 to the object and not to a back-end temporary.
11369 (Freeze_Subprogram): In case of primitives of tagged types not defined
11370 at the library level force generation of code to register the primitive
11371 in the dispatch table. In addition some code reorganization has been
11372 done to leave the implementation clear.
11373 (Expand_Call): When expanding an inherited implicit conversion,
11374 preserve the type of the inherited function after the intrinsic
11375 operation has been expanded.
11376
11377 * exp_ch2.ads, exp_ch2.adb
11378 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11379 of an entry formal appearing in an assignment statement does not assign
11380 to the formal.
11381 (Expand_Current_Value): Instead of calling a routine to determine
11382 whether the prefix of an attribute reference should be optimized or
11383 not, prevent the optimization of such prefixes all together.
11384
11385 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11386 component whose prefix is known to be of an access type is an implicit

11406 make an entry into table to link associated node and new itype.
11407 (Resolve_Record_Aggregate): Do not add an others box association for a
11408 discriminated record component that has only discriminants, when there

11463 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11464 originally being done in a couple of cases), to ensure that the
11465 Extra_Formals list gets set on the entity E when the first entity is
11466 added.
11467 (Conforming_Types): Add missing calls to Base_Type to the code that
11468 handles anonymous access types. This is required to handle the
11469 general case because Process_Formals builds internal subtype entities
11470 to handle null-excluding access types.
11471 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11472 functions that need it, even when not marked Requires_Overriding.
11473 Improve warnings for in out parameters

11478 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11479 the implicit conversion of the expression done for anonymous access
11480 types. This is required to generate the code of the null excluding
11481 check (if required).
11482
11483 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11484 A formal parameter is never publicly referenceable outside of its body.
11485 (Check_References): For an unreferenced formal parameter in an accept
11486 statement, use the same warning circuitry as for subprogram formal
11487 parameters.
11488 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11489 Output_Unreferenced_Messages, containing the part of that routine that
11490 is now reused for entry formals as described above.
11491 (Goto_Spec_Entity): New function

11503 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11504 (Expand_N_Attribute_Reference): Further unify the handling of the
11505 three forms of access attributes, using common code now for all three
11506 cases. Add a test for the case of applying an access attribute to
11507 an explicit dereference when the context is an access-to-interface
11508 type. In that case we need to apply the conversion to the prefix
11509 of the explicit dereference rather than the prefix of the attribute.
11510 (Attribute_Version, UET_Address): Set entity as internal to ensure
11511 proper dg output of implicit importation.
11512 (Expand_Access_To_Type): Removed.
11513 (Expand_N_Attribute_Reference): Merge the code from the three cases
11514 of access attributes, since the processing is largely identical for
11515 these cases. The substantive fix here is to process the case of a
11516 type name prefix (current instance case) before handling the case
11517 of interface prefixes.

11534 initialization of secondary tags.
11535 (Is_Variable_Size_Record): New implementation.
11536 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11537 Suppress_Initialization pragma for a derived type.
11538 (Is_Variable_Size_Record): New subprogram.
11539 (Build_Offset_To_Top_Functions): New implementation that simplifies the

11543 the tag components of secondary dispatch tables.
11544 (Init_Secondary_Tags): New implementation that simplifies the previous

11547 object declaration, for diagnostic purposes.
11548 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11549 diagnose attemps to freeze a subprogram when some untagged type of its
11550 profile is a private type whose full view has not been analyzed yet.
11551 (Freeze_Array_Type): Generate init proc for packed array if either
11552 Initialize or Normalize_Scalars is set.
11553 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when

11558 Create wrappers for constructor functions that need it, even when not
11559 marked Requires_Overriding.
11560 (Covers): Handle properly designated types of anonymous access types,

11562 (Add_Entry): Use an entity to store the abstract operation which hides
11563 an interpretation.

11569 (Has_Compatible_Type): Remove machinery that skips interpretations if
11570 they are labeled as potentially hidden by an abstract operator.

11572 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11573 (Write_Overloads): Output the abstract operator if present.
11574 (Add_Entry): Before inserting a new entry into the interpretation table
11575 for a node, determine whether the entry will be disabled by an abstract
11576 operator.
11577 (Binary_Op_Interp_May_Be_Hidden): New routine.
11578 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11579 aggregate.
11580 (Function_Interp_May_Be_Hidden): New routine.
11581 (Has_Compatible_Type): Do not consider interpretations hidden by
11582 abstract operators when trying to determine whether two types are
11583 compatible.
11584 (Has_Hidden_Interp): New routine.

11598 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11599 output of implicit importation and exportation.
11600 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11601 first formal of the thunk is always associated with the controlling
11602 type. In addition perform the following code cleanup: remove formal
11603 Thunk_Alias which is no longer required, cleanup evaluation of the
11604 the controlling type, and update the documentation.
11605 Replace occurrence of Default_Prim_Op_Count by
11606 Max_Predef_Prims. Addition of compile-time check to verify
11607 that the value of Max_Predef_Prims is correct.
11608 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11609 (Make_DT): Add parameter to indicate when type has been frozen by an
11610 object declaration, for diagnostic purposes.
11611 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11612 construction of statically allocated dispatch tables.
11613 (Make_DT): In case of library-level tagged types export the declaration
11614 of the primary tag. Remove generation of tags (now done by Make_Tags).
11615 Additional modifications to handle non-static generation of dispatch
11616 tables. Take care of building tables for asynchronous interface types
11617 (Make_Tags): New subprogram that generates the entities associated with
11618 the primary and secondary tags of Typ and fills the contents of Access_
11619 Disp_Table. In case of library-level tagged types imports the forward
11620 declaration of the primary tag that will be declared later by Make_DT.
11621 (Expand_Interface_Conversion): In case of access types to interfaces
11622 replace an itype declaration by an explicit type declaration to avoid

11628
9e81dbc7 11629 * exp_util.ads, exp_util.adb:
ab6328d0
AC		 11630 This patch replaces a number of occurrences of explicit tests for N_Null
11631 with calls to Known_Null. This improves tracking of null values, since
11632 Known_Null also catches null constants, and variables currently known to
11633 be null, so we get better tracking.
11634 (Ensure_Defined): create an itype reference only in the scope of the
11635 itype.
11636 (Side_Effect_Free): A selected component of an access type that
11637 denotes a component with a rep clause must be treated as not
11638 side-effect free, because if it is part of a linked structure its
11639 value may be affected by a renaming.
11640 (Expand_Subtype_From_Expr): For limited objects initialized with build
11641 in place function calls, do nothing; otherwise we prematurely introduce
11642 an N_Reference node in the expression initializing the object, which
11643 breaks the circuitry that detects and adds the additional arguments to
11644 the called function. Bug found working in the new patch for statically
11645 allocated dispatch tables.
11646 (Is_Library_Level_Tagged_Type): New subprogram.
11647 (Remove_Side_Effects): If the expression of an elementary type is an
11648 operator treat as a function call.
11649 (Make_Literal_Range): If the index type of the array is not integer, use
11650 attributes properly to compute the constraint on the resulting aggregate
11651 which is a string.
11652
11653 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11654 class-wide type whose base type is an incomplete private type, leave
11655 class-wide type unfrozen so that freeze nodes can be generated
11656 properly at a later point.
11657 (Freeze_Entity, array case): Handle case of pragma Pack and component
11658 size attributre clause for same array.

12285 of Set_Item.
12286 (Set_Item): When the new item is an element of the currently allocated
12287 table passed by reference, save a copy on the stack if we're going
12288 to reallocate. Also, in Table.Set_Item, make sure we test the proper
12289 variable to determine whether to call Set_Last.

12304 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
12305 derived type with interface progenitors use the analyzed formal as the
12306 parent of the actual, to create renamings for all the inherited
12307 operations in Derive_Subprograms.
12308 (Collect_Previous_Instances): new procedure within of
12309 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12310 unit being loaded, to ensure that the generation of global symbols is
12311 consistent in different compilation modes.
12312 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12313 takes progenitor types into account.
12314 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12315 traversing over the primitives of the formal and actual types to locate
12316 any abstract subprograms of the actual type that correspond to a
12317 nonabstract subprogram of the formal type's ancestor type(s), and issue
12318 an error if such is found.
12319 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12320 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12321 Remove bogus guard around calls to Inherit_Context.

12323 that denotes a named number, propagate constant-folding to the generic
12324 template only if the named number is global to the generic unit.
12325 (Set_Instance_Env): Only reset the compilation switches when compiling
12326 a predefined or internal unit.

12331 parameter to determine whether operation applies to the prefix.
12332 (Complete_Object_Operation): If actual has an access type and
12333 controlling formal is not an in_parameter, reject the actual if it is
12334 an access_to_constant type.
12335 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12336 type, the candidate operations are found in the scope of declaration of
12337 the type, because the type has no primitive subprograms.
12338 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12339 a private extension, only examine visible components before trying to
12340 analyze as a prefixed call.
12341 Change Entity_List to Type_To_Use, for better readability.

12351 formal At_Any_Place indicating, when True, that we want to test for
12352 availability of the stream attribute at any place (as opposed to the
12353 current visibility context only).
12354 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12355 purpose of enforcing E.2.2(8) only if it is not available at any place.
12356 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12357 when checking the legality of an extension aggregate in a preelaborable
12358 package. Treat the literal null as a valid default expression in a
12359 component declaration for a type with preelaborable initialization.
12360 A limited interface is a legal progenitor for the designated type of a
12361 remote access to class-wide type.

12373 mark the full view as referenced, to prevent spurious warnings.
12374 (Find_Selected_Component, Has_Components): Handle properly non-limited
12375 views that are themselves incomplete types.
12376 Handle interfaces visible through limited-with clauses.
12377 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12378 subprogram generic actual for which we have generated a renaming.

12389 the allocator is not a coextension.
12390 (Resolve): Skip an interpretation hidden by an abstract operator only
12391 when the type of the interpretation matches that of the context.
12392 (Resolve): When looping through all possible interpretations of a node,
12393 do not consider those that are hidden by abstract operators.
12394 (Resolve_Actuals): When verifying that an access to class-wide object
12395 is an actual for a controlling formal, ignore anonymous access to
12396 subprograms whose return type is an access to class_wide type.
12397 (Resolve_Slice): If the prefix of the slice is a selected component
12398 whose type depends on discriminants, build its actual subtype before
12399 applying range checks on the bounds of the slice.
12400 (Valid_Conversion): In an instance or inlined body, compare root types,
12401 to prevent anomalies between private and public views.
12402 (Resolve): Improve error message for ambiguous fixed multiplication
12403 expressions that involve universal_fixed multiplying operations.

12423 elabration statements, register the package with the name server
12424 at the beginning, not at the end, of the elaboration statements so
12425 that they can create remote access to subprogram values that designate
12426 remote subprograms from the package.

12636 Add s-osinte-vxworks-kernel.adb to the target pairs of the
12637 kernel run-time lib for VxWorks 6, which would provide a different
12638 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
12639 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
12640 running ZCX by default.

13168 to compare the sizes.
13169 (convert_vms_descriptor): When converting to a fat pointer type, be

13477 make_aligning_type for super-aligned objects allocated from the default
13478 pool. Leave enough room for a pointer before the aligning field, and
13479 store the system's allocator return value there.
13480 (build_call_alloc_dealloc): When releasing a super-aligned object,
13481 retrieve the system's allocator return value from where build_allocator
13482 has stored it, just ahead of the adjusted address we are passed.
13483 (build_call_raise): Handle properly the generation of line numbers when
13484 the node is marked No_Location.

13515 Zero_Formatting is set.
13516 Add case for CLI_Target.

13518 System_Restrictions and initialization of the data unless there is
13519 some use of System.Restrictions in the partition.
13520 (Check_System_Restrictions_Used): New procedure

13542 which the address-clause is applied to in-mode actuals (allowed by
13543 13.1(22)).
13544 (Apply_Discriminant_Check): Do not generate a check if the type is
13545 constrained by a current instance.
13546 (Activate_Division_Check): New procedure
13547 (Activate_Overflow_Check): New procedure
13548 (Activate_Range_Check): New procedure

13551 Code clean up: remove obsolete code related to GCC 2.
13552 (Get_E_Length): Protect against bomb in case scope is standard
13553 (Selected_Range_Checks): If the node to be checked is a conversion to
13554 an unconstrained array type, and the expression is a slice, use the
13555 bounds of the slice to construct the required constraint checks.
13556 Improve NOT NULL error messages
13557 (Apply_Constraint_Check): If the context is a null-excluding access
13558 type, diagnose properly the literal null.
13559

13575
13576 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13577 applicable to types that have the With_Type flag set. Returns the
13578 non-limited view of the type, if available, otherwise the type itself.
13579 For class-wide types, there is no direct link in the tree, so we have
13580 to retrieve the class-wide type of the non-limited view of the Etype.
13581 New attributes Static_Initialization and Static_Elaboration_Desired.
13582 Remove the pragma Thread_Body, and the associated flag
13583 Is_Thread_Body in entities, and all related code.
13584 (Suppress_Value_Tracking_On_Call): New flag

13586 (Universal_Aliasing): New function.

13591 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13592 (Related_Interface): New attribute. Present in dispatch table pointer
13593 components of records. Set to point to the entity of the corresponding
13594 interface type.
13595 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13596 (Original_Access_Type): Remove, not needed.
13597 (Root_Type): Handle properly subtypes of class-wide-types.
13598 Update comments.
13599
13600 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13601 class-wide types visible through limited-with clauses.
13602 (Try_Primitive_Operation): When examining all primitive operations of a
13603 tagged type, do not consider subprograms labeled as hidden unless they
13604 belong to a private generic type with a tagged parent.
13605 (Try_Object_Operation): Extensive rewriting, to handle properly various
13606 overloading cases, when several ancestors may have class-wide operations
13607 that are possible candidates, and when the overloaded functions return
13608 array types and have defaulted parameters so that the call may be
13609 interpreted as an indexing.
13610 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13611 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13612 successive actuals before analyzing the call itself.
13613 (Try_Primitive_Operation): A primitive operation is compatible with the
13614 prefix if the prefix has a synchronized type and the type of the formal
13615 is its corresponding record, as can be the case when the primitive
13616 operation is declared outside of the body of the type.
13617 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13618 perform homonym traversal, looking for class-wide operation matches
13619 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13620 access parameters are now restricted to anonymous access types.
13621 (Mark_Allocator): An allocator with a discriminant association parent is
13622 a coextension.
13623 (Try_One_Prefix_Interpretation): If the type of the object is
13624 incomplete, as can be happen when it is a limited view obtained through
13625 a limited_with_clause, the selected component is not part of a prefixed
13626 call.
13627 (Complete_Object_Operation): Diagnose properly an object that is not
13628 aliased when the corresponding controlling formal is an access
13629 parameter.
13630 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13631 ambiguous calls in prefixed notation, where two primitives differ only
13632 in that the controlling argument of one is an access parameter.
13633
13634 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13635 whether a function that returns an unconstrained type can be inlined.
13636 (Process_Formals): Diagnose properly the illegal use of an incomplete
13637 type in the profile of an access_to_subprogram declaration.
13638 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13639 operations are attached to the corresponding record.
13640 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13641 When processing a primitive of a concurrent type which implements an
13642 interface change the type of all controlling formals to that of the
13643 corresponding record type.
13644 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13645 to determine the tagged type to which a primitive belongs.
13646 (Check_Conventions): Capture condition to ignore a primitive operation
13647 (which is shared between the loop in Check_Conventions and the one in
13648 Check_Convention) in a new local function Skip_Check.
13649 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13650 confusion with Check_Conventions' own Prim_Op local variable.
13651 (Create_Extra_Formals): Test for a tagged result type rather than a
13652 controlling result when determining whether to add a BIP_Alloc_Form
13653 formal and a BIP_Final_List formal to the function.
13654 (Check_Conformance); For parameters that are anonymous access types,
13655 subtype conformance requires that the not null and the constant
13656 indicators must match
13657 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13658 to retrieve the appropriate type when processing a concurrent type
13659 declared within a generic. Minor comment reformatting. Change invocation
13660 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13661 mitive.
13662 (Analyze_Subprogram_Body): If the return type of a function is an
13663 anonymous access to the limited view of a class-wide type, and the
13664 non-limited view of the type is available, update the type of the
13665 function so that code can be generated.
13666 (Process_Formals): In case of access-subtype itype whose designated
13667 type is also an itype (situation that happens now with access to
13668 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13669 attribute to avoid backend problems.
13670 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13671 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13672 anonymous types' designated types are same before testing
13673 Subtypes_Statically_Match.
13674 (Create_Extra_Formals): Test for a named access parameter that is a
13675 controlling formal as an additional condition for adding an
13676 accessibility level formal. This can occur in the subp type created for
13677 dispatching calls in Expand_Dispatching_Call, and allows calling
13678 Create_Extra_Formals from that procedure rather than special-casing the
13679 extra formals there.
13680 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13681 when the function has a controlling result.
13682 (Check_Returns): Add much more knowledge of the optimization of local
13683 raise statements to gotos, to retain proper warnings in this case.
13684 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13685 nodes when looking for last statement.
13686
13687 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13688 class-wide types visible through limited with clauses.
13689 (Add_One_Interp): If the operands are anonymous access types, the
13690 predefined operator on universal_access is immediately visibles
13691 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13692 other anonymous access types.
13693 (Disambiguate): Take into account CIL convention.
13694 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13695
136962007-06-06 Robert Dewar <dewar@adacore.com>

13700 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13701 Fix lower bound of tables.
13702 Add rep clauses.
13703
13704 * nlists.adb: Ditto.
13705 (Prev_Node, Next_Node): Change index type to Int so that it properly
13706 covers the range First_Node_Id - 1 up.

9e81dbc7 13713 * exp_aggr.ads, exp_aggr.adb:
ec11296f
AC		 13714 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13715 in extension aggregates.
13716 (Flatten): Other conditions being met, an aggregate is static if the
13717 low bound given by component associations is different from the low
13718 bound of the base index type.
13719 (Packed_Array_Aggregate_Handled): If the component type is itself a
13720 packed array or record, the front-end must expand into assignments.
13721 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13722 Init_Pr, instead of Ancestor_Is_Expression.
13723 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13724 coextension chain root, either generate a list controller or use the
13725 already existing one.
13726 (Static_Array_Aggregate): New procedure to construct a positional
13727 aggregate that can be handled by the backend, when all bounds and
13728 components are compile-time known constants.
13729 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13730 types covering interface types into assignments.
13731 (Replace_Type): move to Build_Record_Aggr_Code.
13732 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13733 interface type, convert to the definite type of the aggregate itself,
13734 so that needed components are visible.
13735 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13736 components and the context is an extended return statement do not
13737 create a transient block for it, to prevent premature finalization
13738 before the return is executed.
13739 (Gen_Assign): Do not generate a call to deep adjust routine if the
13740 component type is itself an array of controlled (sub)-components
13741 initialized with an inner aggregate.
13742 (Component_Check): New name for Static_Check. This name is now more
13743 appropriate, and documentation is added which was missing.
13744 (Component_Check): Add test for bit aligned component value
13745 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13746 Tagged_Comps, name is more appropriate given added function below.
13747 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13751 Robert Dewar <dewar@adacore.com>
13752
13753 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13754 Terminated: Add unchecked type conversion from System.Address to
13755 System.Tasking.Task_Id when calling the predefined primitive
13756 _disp_get_task_id.
13757 Disable new Ada 05 accessibility check for JVM.NET targets, which
13758 cannot be implemented in a practical way.
13759 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13760 the sources always references the tag of the actual object. Therefore,
13761 if 'Tag is applied in the sources to class-wide interface objects we
13762 generate code that displaces "this" to reference the base of the object.
13763 (Expand_N_Attribute_Reference, case Size): Return specified size if
13764 known to front end.
13765 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13766 has code that displaces the pointer of the object to manage interface
13767 types. However this code must not be executed when the prefix is a
13768 subprogram. This bug caused the wrong expansion of the internally
13769 generated assignment that fills the dispatch table when the primitive
13770 is a function returning a class-wide interface type.
13771 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13772 Set_Attribute_Name for Name_Unaligned_Valid.

13781 initialized to null from having their expression reset to empty and
13782 note this exception in the comment.

13797 (Name_Modifies_Prefix): Body of new function.
13798 (Requires_Simple_Name_Prefix): Body of new function.
13799 (Resolve_Attribute, case Access): Improve error message for case of
13800 mismatched conventions.
13801 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13802 incomplete type.
13803 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13804 constrained subtype for a nominal unconstrained type, use its base type
13805 to check for conformance with the context.
13806 (Resolve_Attribute): Remove test of the access type being associated
13807 with a return statement from condition for performing accessibility
13808 checks on access attributes, since this case is now captured by
13809 Is_Local_Anonymous_Access.
13810 (Analyze_Access_Attribute): Set Address_Taken on entity
13811 (Analyze_Attribute, case Address): Set Address_Taken on entity
13812 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13813 validating an access attribute whose prefix is a current instance.
13814 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13815 applied to dispatching operations, if freezing is required then we set
13816 the attribute Has_Delayed_Freeze in the prefix's entity.
13817 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13818 current scope if access of local subprogram taken
13819 (Analyze_Access_Attribute): Check legality of self-reference even if the
13820 expression comes from source, as when a single component association in
13821 an aggregate has a box association.
13822 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13823 the prefix if it is a protected operation and the attribute is
13824 Unrestricted_Access.
13825 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13826 reference to the base type of the context, to force a constraint check
13827 when the context is an access subtype with an explicit constraint.
13828 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13829 node is rewritten as an interface conversion. leave unanalyzed after
13830 resolution, to ensure that type checking against the context will take
13831 place.

13835 Robert Dewar <dewar@adacore.com>
13836
13837 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13838 wrapper when the full view of the controlling type of an inherited
13839 function that dispatches on result implements interfaces.
13840 (Expand_N_Object_Declaration): In cases where the type of the
13841 declaration is anonymous access, create finalization list for it.
13842 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13843 if the object has no explicit initialization, to match description of
13844 functionality of pragam Persistent_BSS.
13845 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13846 new function to build static aggregates, to replace initialization call
13847 when static initialization is desired.
13848 (Freeze_Type): Generate a list controller for an access type whenever
13849 its designated type has controlled anonymous access discriminants.
13850 (Build_Equivalent_Aggregate): New procedure to compute a static
13851 aggregate to be used as default initialization for composite types,
13852 instead of a generating a call to the initialization procedure for the
13853 type.
13854 (Build_Initialization_Call): When available, replace a call to the
13855 initialization procedure with a copy of the equivalent static aggregate
13856 for the type.
13857 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13858 declarations for objects of a class-wide interface type, rather than
13859 just identifiers, to prevent visibility problems.
13860 (Expand_N_Object_Declaration): When expanding the declaration for an
13861 object of a class-wide interface type, preserve the homonym chain of
13862 the original entity before exchanging it with that of the generated
13863 renaming declaration.
13864 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13865 active, because there is no way to handle the exception.
13866 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13867 to do a minimum decoration of the Access_Disp_Table list.
13868 (Expand_Record_Controller): Avoid the addition of the controller between
13869 the component containing the tag of a secondary dispatch table and its
13870 adjacent component that stores the offset to the base of the object.
13871 This latter component is only generated when the parent type has
13872 discriminants ---documented in Add_Interface_Tag_Components).
13873 (Apply_Array_Size_Check): Removed, no longer needed.
13874 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13875 components, create a Master_Entity for it only if it contains tasks.
13876 (Build_Init_Procedure): Suppress the tag assignment compiling under
13877 no run-time mode.
13878 (Freeze_Record_Type): Remove code associated with creation of dispatch
13879 table.
13880 (Init_Secondary_Tags): Update type of actuals when generating calls to
13881 Ada.Tags.Set_Offset_To_Top
13882 (Stream_Operation_OK): Disable use of streams compiling under no
13883 run-time mode
13884 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13885 if Has_Init_Expression set.
13886 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13887 Register_Primitive, which provides the same functionality.
13888 (Requires_Init_Proc): Return false in case of interface types.
13889 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13890 cleanup the code.
13891 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13892 is always associated with a predefined primitive because the internal
13893 entities associated with interface types are not predefined primitives.
13894 Therefore, the call to Is_Internal is replaced by a call to the
13895 function Is_Predefined_Dispatching_Operation.
13896 (Make_Eq_If): When generating the list of comparisons for the
13897 components of a given variant, omit the controller component that is
13898 present if the variant has controlled components.

13902 Bob Duff <duff@adacore.com>
13903
13904 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13905 handle the creation of finalization lists and calls for nested
13906 coextensions when the root of the chains is part of a return statement.
13907 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13908 Finalization.
13909 (Expand_Record_Equality): Skip components that are interface types.
13910 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13911 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13912 with Rewrite_Coextension. Change the condition for detecting coextension
13913 root nodes.
13914 (Is_Local_Access_Discriminant): Removed.
13915 (Rewrite_Coextension): New routine which rewrites a static coextension
13916 as a temporary and uses its unrestricted access in the construction of
13917 the outer object.
13918 (Complete_Coextension_Finalization): New routine. Generate finalization
13919 attachment calls to all delayed coextensions.
13920 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13921 the allocator is not a coextension itself and has delayed coextensions.
13922 If the current allocator is controlled, but also a coextension, delay
13923 the generation of the finalization attachment call.
13924 Rename local variable "Node" to "Nod" in order to avoid confusion with
13925 "Elists.Node".
13926 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13927 limited types that are not inherently limited. Such an allocator is
13928 illegal, but is generated by the expander for a return statement, to
13929 copy the result onto the secondary stack. This is the only case where a
13930 limited object can be copied. Generate code to displace the pointer
13931 to the object if the qualified expression is a class-wide interface
13932 object. Such displacement was missing and hence the copy of the object
13933 was wrong.
13934 (Apply_Accessibility_Check): Handle allocated objects initialized in
13935 place.
13936 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13937 and Expand_Allocator_Expression. Allocating class-wide interface objects
13938 this routine displaces the pointer to the allocated object to reference
13939 the component referencing the corresponding secondary dispatch table.
13940 Expand_Allocator_Expression): Add missing support to allocate class-wide
13941 interface objects initialized with a qualified expression.
13942 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13943 function result type, and use the finalization list associated with the
13944 function scope in that case (such an anonymous type should not be
13945 treated like an access parameter's type).
13946
139472007-06-06 Ed Schonberg <schonberg@adacore.com>
13948 Gary Dismukes <dismukes@adacore.com>
13949 Javier Miranda <miranda@adacore.com>
13950
13951 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13952 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13953 required exception handler.
13954 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13955 properly the case of a function whose return type is a limited
13956 class-wide interface type. Modify the code of the accessibility
13957 check to handle class-wide interface objects. In this case we need to
13958 displace "this" to reference the primary dispatch table to get access
13959 to the TSD of the object (to evaluate its accessibility level).
13960 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13961 rather than a controlling result as one of the conditions for
13962 generating tests of the implicit BIP_Alloc_Form formal. The
13963 initialization assignment is also handled according to whether the
13964 result is tagged instead of controlling.
13965 In the case where the init assignment is inserted in the "then" part of
13966 the allocation conditional, rewrite the target to be a dereference of
13967 the implicit BIP_Object_Access formal.
13968 If the returned value is unconstrained and created on the secondary
13969 stack, mark the enclosing block and function so that the secondary
13970 stack is not reclaimed on return.
13971 Treat returns from functions with controlling results similarly to
13972 returns from functions with unconstrained result subtypes.
13973 If the object returned is unconstrained, and an allocator must be
13974 created for it, analyze the allocator once the block for the extended
13975 return is installed, to ensure that finalizable components
13976 of the expression use the proper finalization list. Guard the call to
13977 Move_Final_List with a check that there is something to finalize.
13978 (Make_Tag_Ctrl_Assignment): Use "old" handling
13979 of controlled type assignment for virtual machines, since new code uses
13980 unsupported features (such as direct access to bytes in memory).
13981
139822007-06-06 Gary Dismukes <dismukes@adacore.com>
13983 Ed Schonberg <schonberg@adacore.com>
13984
13985 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13986 accessibility actual, check for the case of an aliased object that has
13987 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13988 we fall into processing for the attribute rather than the name of the
13989 object.
13990 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13991 formal has its address taken in the body, create a temporary to capture
13992 value. If the return type is a limited interface, do not treat the
13993 return value as Controlled.
13994 (Is_In_Place_Function): If the return type is a limited interface,
13995 treat as returning in place. The actual returned object may not always
13996 be limited, but the caller has to assume that it is returned in place.
13997 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13998 context of an allocator, use the correct finalization chain (that is,
13999 the chain belonging to the access type, rather than the chain belonging
14000 to the current scope).
14001 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
14002 result type rather than a controlling result as a precondition for
14003 adding an allocation form actual to a build-in-place call.
14004 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
14005 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
14006 primitive in the dispatch tables. This work is now done by Make_DT when
14007 the type is frozen.
14008 (Register_Predefined_DT_Entry): Removed.
14009 (Add_Return): If end label is not present, use sloc of last statement
14010 for generated return statement in procedure, for better gdb behavior
14011 on expanded code.
14012 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
14013 object address nodes to ensure proper processing by routines like
14014 Insert_After*.
14015 (Expand_Call): Fix generation of validity check for parameter
14016 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
14017 the allocation form parameter if the result subtype is constrained,
14018 except when the function has a controlling result.
14019 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
14020 rather than Is_Controlled and Has_Controlled_Component, since we want to
14021 include class-wide result types in this treatment. Also test for a
14022 controlling result, since that also requires passing a finalization
14023 list.
14024 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
14025 even when the result subtype is constrained, to handle calls involving
14026 controlling results.
14027 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
14028 is now called even when the result subtype is constrained, to handle
14029 calls involving controlling results.
14030 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
14031 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
14032 now performs the test).
14033 (Make_Build_In_Place_Call_In_Object_Declaration):
14034 Add_Alloc_Form_Actual_* is now called even when the result subtype is
14035 constrained, to handle calls involving controlling results.
14036 (Add_Return): Accomodate rewritten pattern from local raise to goto
14037 transformation, so that we still recognize an transfer statement
14038 and do the right thing here in that case.
14039 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
14040 and end of subprogram code.
14041 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14042 support for primitives that are functions (without formals) with a
14043 controlling result.
14044 (Inherited_From_Formal): If the actual subtype has not generic parent
14045 type, it is not an actual for a formal derived type, and there is no
14046 operation to inherit from the formal.
14047

14049 Thomas Quinot <quinot@adacore.com>
14050
14051 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
14052 inserted cleanup code appropriately for GDB use.
14053 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
14054 exception handler for Deep_Adjust or Deep_Finalize.
14055 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14056 Raise_From_Controlled_Operation is available, use a call to that
14057 subprogram instead of a plain "raise Program_Error" node to raise
14058 Program_Error if an exception is propagated from an Adjust or Finalize
14059 operation.
14060 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14061 appears in the optional statement list of a triggering alternative, the
14062 scope actions can be inserted directly there, and not in the list that
14063 includes the asynchronous select itself.
14064

14067 Hristian Kirtchev <kirtchev@adacore.com>
14068
14069 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
14070 generated exception handler appropriately when debugging generated code.
14071 Deal properly with No_Exception_Propagation restriction mode.
14072 (Expand_N_Abort_Statement): Add an unchecked type conversion from
14073 System.Address to System.Tasking.Task_Id when processing the result of
14074 the predefined primitive _disp_get_task_id.
14075 (Expand_N_Asynchronous_Select): Clarify comment.
14076 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
14077 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
14078 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
14079 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
14080 privals and for generated call to Complete_Entry_Body, for better gdb
14081 behavior.
14082 (Copy_Result_Type): Utility to construct a parameter and result profile
14083 for protected functions whose return type is an anonymous access to
14084 subprogram.
14085 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
14086 call the above.
14087 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
14088 point when the local-raise-to-goto transformation has taken place.
14089
140902007-06-06 Javier Miranda <miranda@adacore.com>
14091 Nicolas Setton <setton@adacore.com>
14092
14093 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14094 functionality when the backend is generating code.
14095 Otherwise any serious error
14096 reported by the backend calling the frontend routine Error_Msg
14097 changes the Compilation_Mode to Check_Semantics, disables the
14098 functionality of this routine and causes the generation of
14099 spureous additional errors.
14100
14101 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14102 debugging information now generated by the compiler for fat-pointer
14103 types.
14104 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
14105 DWARF2/3.
14106 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
14107
141082007-06-06 Thomas Quinot <quinot@adacore.com>
14109
14110 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
14111 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14112 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14113 For a remote call to a function with a classwide return type, apply an
14114 E.4(18) check to the returned value.
14115 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
14116 stream attributes of the designated type of an RACW, as they are not
14117 dispatching primitive operations.
14118
141192007-06-06 Geert Bosch <bosch@adacore.com>
14120
14121 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
14122 negative literal
14123 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
14124 positive
14125 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
14126 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
14127 positive
14128 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
14129
141302007-06-06 Javier Miranda <miranda@adacore.com>
14131
14132 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
14133 attribute compiling package Ada.Tags under No_Run_Time_Mode.
14134
141352007-06-06 Javier Miranda <miranda@adacore.com>
14136
14137 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14138 deallocation of class-wide interface objects.
14139 (Expand_Dispatching_Constructor_Call): Take into account that if the
14140 result of the dispatching constructor is an interface type, the
14141 function returns a class-wide interface type; otherwise the returned
14142 object would be actual. The frontend previously accepted returning
14143 interface types because Expand_Interface_Actuals silently performed
14144 the management of the returned type "as if" it were a class-wide
14145 interface type.
14146 (Expand_Dispatching_Constructor_Call): Replace call to
14147 Make_DT_Access_Action by direct call to Make_Function_Call.
14148
141492007-06-06 Robert Dewar <dewar@adacore.com>
14150 Ed Schonberg <schonberg@adacore.com>
14151
14152 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14153 compute masking constant, since we now set Esize properly to the
14154 underlying size.
14155 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14156 to match the alignment.
14157 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
14158 packed arrays of 8 bits or less.
14159
14160 * freeze.adb (Freeze_Entity): When freezing the formals of a
14161 subprogram, freeze the designated type of a parameter of an access type
14162 only if it is an access parameter.
14163 Increase size of C convention enumeration object
14164 (Freeze_Entity, array type case): Make sure Esize value is properly
14165 adjusted for the alignment if it is known.
14166 (Freeze_Entity, array type case): When checking bit packed arrays for
14167 the size being incorrect, check RM_Size, not Esize.
14168 (Freeze_Record_Type): Check for bad discriminated record convention
14169 (In_Exp_Body): Return true if the body is generated for a subprogram
14170 renaming, either an attribute renaming or a renaming as body.
14171 (Check_Itype): If the designated type of an anonymous access component
14172 is a non-protected subprogram type, indicate that it is frozen, to
14173 prevent out-of-scope freeze node at some subsequent call.
14174 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
14175 only if the subprogram is neither imported nor exported, as well as the
14176 NCA descriptor class if the subprogram is exported.
14177

14182
14183 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
14184 default initialization on an imported object, when there is no
14185 initialization call generated for it.
14186 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
14187 restriction
14188
14189 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
14190 Static_Elaboration_Desired.
14191 Remove pragma Thread_Body.
14192 Implement a new pragma No_Body
14193 Removes the Explicit_Overriding pragma
14194 Remove Optional_Overriding pragma
14195 (Prag): Deal with Universal_Aliasing.
14196 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
14197 Pragma_CIL_Constructor): New names.
14198
14199 * sem_cat.adb (Validate_Object_Declaration): An initialization that
14200 uses the equivalent aggregate of a type must be treated as an implicit
14201 initialization.
14202 (Get_Categorization): Check a unit for pragma Preelaborate only if it
14203 has none of the other categories.
14204 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
14205 to apply Import to an object renaming declaration.
14206
14207 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
14208 from a C++ class should be declared as limited and that it will be
14209 considererd limited.
14210 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class

14575 declaration, to ensure that the interface list is processed correctly.
14576 (Inline_Instance_Body): If enclosing scope is an instance body, remove

14580 discriminant association itself.
14581 (Reset_Entity): If the analysis of a selected component is transformed
14582 into an expanded name in the prefix of a call with parameters, do not
14583 transform the original node into an expanded name, to prevent visibility

14585 (Check_Private_View): For an array type, check whether the index types
14586 may need exchanging.

14710 component declaration, when the prefix is an expanded name.
14711 (Inherit_Component): If the derivation is for a private extension,

14713 to Void.
14714 (Find_Type_Of_Object): In the case of an access definition, always set
14715 Is_Local_Anonymous_Access. We were previously not marking the anonymous

14734 improve the condition that avoids inheriting the components associated
14735 with secondary tags of the parent.

14756 * sem_aggr.adb (Resolve_Record_Aggregate): Ignore internal components
14757 of the type that specify the position of interface tags when the type
14758 inherits discriminated array components from the parent type.
14759 If a component is initialized with a box, check for the presence of a
14760 default expression in its declaration before using its default
14761 initialization procedure.
14762 (Resolve_Record_Aggregate): If a component is box-initialized, and the
14763 component type has a discriminants, create a partial aggregate for it
14764 by copying the discriminants of the component subtype.
14765 Reject attempt to initialize a discriminant with a box.
14766 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
14767 associated with dispatch tables is known at compile time.

14781 not null indicator.
14782
14783 * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If
14784 multiple identifier are present, save Scan_State before scanning the
14785 colon, to ensure that separate trees are constructed for each

14862 unimplemented unit.
14863 (Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a
14864 manner similar to GNAT.Current_Exception. This is a violation of
14865 restriction (No_Exception_Propagation), and also inhibits the
14866 optimization of local raise to goto.
14867 (Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,
14868 and if so set Most_Recent_Exception_Used flag in Opt, and also check

14884 protected type does not implement a task interface or a nonlimited
14885 interface.
14886 (Analyze_Task_Type): Rearrange and simplify code for testing that a task
14887 type does not implement a protected interface or a nonlimited interface.

14892 routines if the expander is not active.
14893 (Analyze_Task_Body): Mark all handlers to stop optimization of local

14957 Do_Division_Check flag explicitly.
14958 (Resolve_Actuals): If the actual is of a synchronized type, and the
14959 formal is of the corresponding record type, this is a call to a
14960 primitive operation of the type, that is declared outside of the type;
14961 the actual must be unchecked-converted to the type of the actual
14962 (Resolve_Call): Kill all current values for any subprogram call if
14963 flag Suppress_Value_Tracking_On_Call is set.
14964 (Resolve_Type_Conversion): Generate error message the the operand
14965 or target of interface conversions come from a limited view.
14966 (Check_Infinite_Recursion): Ignore generated calls
14967 (Check_Allocator_Discrim_Accessibility): New procedure for checking
14968 that an expression that constrains an access discriminant in an

15031 function's result type to determine the level of the return object's
15032 type.

15836 attributes that can be handled directly by the back end.
15837 (Expand_N_Attribute_Reference, case 'Access and 'Unchecked_Access):
15838 use new predicate Is_Access_Protected_Subprogram_Type.
15839 (Expand_N_Attribute_Reference, case 'Write): The reference is legal for
15840 and Unchecked_Union if it is generated as part of the default Output
15841 procedure for a type with default discriminants.
15842 (Expand_N_Attribute_Reference): Avoid the expansion of dispatching calls
15843 if we are compiling under restriction No_Dispatching_Calls.
15844 (Constrained): Use Underlying_Type, in case the type is private without

15865 scope treatment. Update comments to describe this exception.
15866 (Resolve_Equality_Op): In case of dispatching call check violation of
15867 restriction No_Dispatching_Calls.
15868 (Resolve_Call): If the call returns an array, the context imposes the
15869 component type of the array, and the function has one non-defaulted
15870 parameter, rewrite the call as the indexing of a call with a single
15871 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15872 in prefix form.
15873 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15874 the master of the created object is the innermost enclosing statement.
15875 (Remove_Conversions): For a binary operator, check if type of second
15876 formal is numeric, to check if an abstract interpretation is present
15877 in the case of exponentiation as well.

15901 * checks.ads, checks.adb (Selected_Range_Checks): No range check is
15902 required for a conversion between two access-to-unconstrained-array
15903 types.
15904 (Expr_Known_Valid): Validity checks do not apply to discriminants, but
15905 to discriminant constraints on discriminant objects. This rule must
15906 apply as well to discriminants of protected types in private components.
15907 (Null_Exclusion_Static_Checks): If No_Initialization is set on an
15908 object of a null-excluding access type then don't require the

15972 (E_Return_Statement): This node type has the Finalization_Chain_Entity
15973 attribute, in case the result type has controlled parts.
15974 (Requires_Overriding): Add this new flag, because "requires
15975 overriding" is subtly different from "is abstract" (see AI-228).
15976 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15977 Is_Abstract_Type. Make sure these are called only when appropriate.
15978 (Has_Pragma_Unreferenced_Objects): New flag

16010 Add_Task_Actuals_To_Build_In_Place_Call with the appropriate master.
16011 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
16012 stubbed procedure with a null body, replace the call with a null
16013 statement without using the full inlining machinery, for efficiency
16014 and to avoid invalid values in source file table entries.
16015
16016 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Add support for
16017 renamings of calls to build-in-place functions.

16035 unit. If this unit has not been loaded, it returns Empty.
16036 (RTE): Addition of a new formal that extends the search to the scopes
16037 of the record types found in the chain of the package.
16038
16039 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
16040 "abstract subprograms must be visible" message, whether or not the type
16041 is an interface; that is, remove the special case for interface types.

16068 Remove no longer used entities.
16069
16070 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

16110 "X'Unrestricted_Access = Y'Access" and so forth to match.

16123 that use (a subtype of) the class-wide type of the enclosing type.
16124 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
16125 Derived_Type for Prev formal on call to
16126 Check_Anonymous_Access_Components rather than Empty.
16127 (Make_Incomplete_Type_Declaration): Add test for case where the type has
16128 a record extension in deciding whether to create a class-wide type,

16131 to stand-alone object declarations as well as component declarations.
16132 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to

16136 the associated_node for the itype is the type declaration itself.

16139 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
16140 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).

16145 with abstract interfaces.

16157 to private type.
16158 (Analyze_Subtype_Declaration): For an access subtype declaration, create

16222 (Scan_Arg): Set Setup_Projects True when -p or --create-missing-dirs
16223 is specified.
16224 (Initialize): Add the directory where gprmake is invoked in front of the
16225 path, if it is invoked from a bin directory or with directory
16226 information, so that the correct GNAT tools will be used when invoked
16227 directly.
16228 (Check_Compilation_Needed): Process correctly backslashes on Windows.
16229
16230 * vms_data.ads: Update switches/qualifiers

16233 Thomas Quinot <quinot@adacore.com>
16234
16235 * exp_aggr.adb:
16236 If the array component is a discriminated record, the array aggregate
16237 is non-static even if the component is given by an aggregate with
16238 static components.
16239 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
16240 (Convert_Aggr_In_Allocator): If the allocator is for an access
16241 discriminant and the type is controlled. do not place on a finalization
16242 list at this point. The proper list will be determined from the
16243 enclosing object.
16244 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
16245 initialize record controller if needed, before the components, to ensure
16246 that they are properly finalized.
16247 (Build_Record_Aggr_Code): For the case of an array component that has a
16248 corresponding array aggregate in the record aggregate, perform sliding
16249 if required.

16254
16255 * exp_ch13.adb (Expand_External_Tag_Definition): Replace call to the
16256 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
16257
16258 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
16259 accessibility on class-wide allocators if the allocator occurs at the
16260 same scope level as the allocator's type. The check is guaranteed to
16261 succeed in that case, even when the expression originates from a
16262 parameter of the containing subprogram.
16263 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
16264 under No_Dispatching_Calls restriction. During the semantic analysis
16265 we already notified such violation.
16266 (Tagged_Membership): Constant folding. There is no need to check
16267 the tag at run-time if the type of the right operand is non
16268 class-wide abstract.

16270 to support concurrent types with interface types.
16271 (Expand_N_Allocator): Add an assertion associated with the generation
16272 of the master_id.
16273 (Expand_N_Slice): Do not enable range check to nodes associated
16274 with the frontend expansion of the dispatch table.
16275 (Is_Local_Access_Discriminant): Subsidiary function to
16276 Expand_N_Allocator.
16277 (Tagged_Membership): Replace generation of call to the run-time
16278 subprogram CW_Membership by call to Build_CW_Membership.

16280 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
16281
16282 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
16283 initialize most the TSD components by means of an aggregate.
16284 Modify the declaration of the object containing the TSD
16285 because we now expand code that has a higher level of abstraction.
16286 The TSD has a discriminant containing the Inheritance Depth Level,
16287 value that is used in the membership test but also to fix the size
16288 of the table of ancestors.
16289 (Expand_Interface_Conversion): Insert function body at the closest place
16290 to the conversion expression, to prevent access-before-elaboration
16291 errors in the backend.
16292 Code improved to reduce the size of the dispatch table if
16293 compiling under restriction No_Dispatching_Calls plus code cleanup.
16294 Code reorganization plus removal of calls to Set_Num_Prim_Ops
16295 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
16296 (Expand_Dispatching_Call): Minor code reorganization plus addition of
16297 code to return immediately if compiling under No_Dispatching_Calls
16298 restriction.
16299 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
16300 CPP_Virtual and CPP_Vtable are no longer supported.

16302 derivations.
16303 (Expand_Interface_Actuals): Replace calls to Is_Ancestor by calls to
16304 Is_Parent to support concurrent types with interfaces.
16305 (Init_Predefined_Interface_Primitives): Removed.
16306 (Make_Secondary_DT): Modified to support concurrent record types.
16307 (Set_All_DT_Position): Modified to support concurrent record types.
16308 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
16309 with Get_External_Tag, Inherit_TSD, Set_External_Tag.

16311 with CW_Membership.
16312 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
16313 with Get_Access_Level, Get_Predefined_Prim_Op_Address,

16316 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
16317 (Expand_Dispatching_Call): Replace generation of call to the run-time
16318 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
16319 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
16320 Address.
16321 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
16322 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
16323 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
16324 Build_Set_Prim_Op_Address.
16325 (Get_Remotely_Callable): Subprogram removed.
16326 (Init_Predefined_Interface_Primitives): Replace generation of call to
16327 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16328 Prims.
16329
16330 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16331 First (Parameter_Associations ()) with the call to First_Actual that
16332 returns an actual parameter expression for both named and positional
16333 associations.
16334
16335 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
16336 check violation of restriction No_Dispatching_Calls.
16337 (Check_Controlling_Type): A formal of a tagged incomplete type is a
16338 controlling argument.

16340 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
16341 First/Next_Component_Or_Discriminant
16342 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
16343 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16344 specify Any_Limited_Interface, and this functionality is already
16345 provided by the function Has_Abstract_Interfaces.
16346 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16347 support concurrent types implementing interfaces.
16348 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16349 specify kind Any_Limited_Interface, and this functionality is already
16350 provided by the function Has_Abstract_Interfaces.
16351 (Remove_Side_Effects): replace Controlled_Type by
16352 CW_Or_Controlled_Type whenever the issue is related to
16353 using or not the secondary stack.
16354
16355 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16356 P_Interface_Type_Definition to fulfill the new interface (the formal
16357 Is_Synchronized is no longer required).
16358
16359 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
16360 Update dependencies.
16361
16362 * exp_atag.ads, exp_atag.adb: New file

16369 anonymous, use finalization list of enclosing dynamic scope.
16370 (Expand_N_Package_Declaration): For a library package declaration
16371 without a corresponding body, generate RACW subprogram bodies in the
16372 spec (just as we do for the task activation call).
16373 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
16374 Is_Abstract_Type. Make sure these are called only when appropriate.
16375 Remove all code for DSP option
16376 (CW_Or_Controlled_Type): new subprogram.

16381
16382 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
16383 parameter. If it is set to true, return a result capped according to
16384 the global upper bound for the index of an entry family.
16385 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
16386 (Build_Find_Body_Index): Adjust for above change.
16387 (Entry_Index_Expression): Likewise.
16388 (Is_Potentially_Large_Family): New function extracted from...

16390 is potentially large.
16391 (Build_Entry_Count_Expression): If the family is potentially large, call
16392 Family_Size with 'Cap' set to true.
16393 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16394 a protected version of an operation declared in the private part of
16395 a protected object, because they may be invoked through a callback.
16396 (Set_Privals): If the type of a private component is an anonymous access
16397 type, do not create a new itype for each protected body.
16398 If the body of a protected operation creates
16399 controlled types (including allocators for class-widetypes), the
16400 body of the corresponding protected subprogram must include a
16401 finalization list.
16402 (Build_Activation_Chain_Entity): Build the chain entity for extended
16403 return statements.
16404 (Type_Conformant_Parameters): Use common predicate Conforming_Types
16405 to determine whether operation overrides an inherited primitive.
16406 (Build_Wrapper_Spec): Add code to examine the parents while looking
16407 for a possible overriding candidate.
16408 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16409 hold an actual parameter value since its initialization is separated
16410 from the the declaration. Prevents errors on null-excluding access
16411 formals.

16416 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16417 Do an Unchecked_Conversion to handle the passage from the Underlying
16418 Type to the Base Type when calling Build_To_Any_Call and
16419 Build_From_Any_Call.
16420 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16421 E_Constant, depending upon Variable formal.
16422 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16423 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16424 parameter that requires an extra constrained parameter, declare
16425 temporary for actual as a variable, not a constant.
16426 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16427 the unit being compiled is the one that contains the stub type.
16428 Change primitive operation name for the RACW associated with a RAS
16429 from Call to _Call so it cannot clash with any legal identifier.
16430 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16431 Is_RAS.
16432 (Append_RACW_Bodies): New subprogram.
16433 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16434 Add_Receiving_Stubs_To_Declarations functions.
16435 When expanding a package body, this list correspond to the
16436 statements in the HSS at the end of the pacakge.
16437 When expanding a package spec, this list correspond to the
16438 spec declarations.
16439 (Add_Receiving_Stubs_To_Declarations): Append the function
16440 registering the receiving stubs at the end of the 'Stmts' list.
16441 (RCI_Package_Locator): Pass the new Version generic formal when
16442 instantiating a RCI_Locator package.
16443 (Build_From_Any_Function): To compute the High bound for an
16444 unconstrained array actual, we add the Low bound with the length.
16445 Thus we must convert the low bound and the length to an appropriate
16446 type before doing the sum.
16447 (Build_Subprogram_Receiving_Stubs, PolyORB):
16448 * Retrieve the extra formals parameters at the
16449 end of the parameter stream.
16450 * Use Move_Any_Value to write back out parameters
16451 after executing the request as it is more efficient
16452 than Copy_Any_Value.
16453 * Build the any containing Extra Formals with the
16454 appropriate typecode.
16455 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16456 empty Component_List.
16457 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

16461 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16462 Use Build_Actual_Object_Declaration to prepare the actuals.
16463 (Add_Parameter_To_NVList): Set the parameter mode to In for
16464 Extra Constrained Parameters.
16465 (Build_General_Calling_Stubs): Set the parameter type to boolean for
16466 Extra Constrained parameters.
16467 (Build_To_Any_Function, Build_From_Any_Function,
16468 Built_TypeCode_Function): When Typ is implicit, call the correct
16469 function with the first not implicit parent type.
16470 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16471 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16472 typecode from the Etype. Therefore we retrieve the correct typecode
16473 with a call to Get_Any_Type.
16474 (Copy_Specification): Do controlling formal type substitution based on
16475 Is_Controlling_Formal flag, instead of caller-provided object type.
16476 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16477 a RACW primitive operation, we might get a subprogram declaration for an
16478 ancestor of the RACW designated type (not for the designated type
16479 itself), in the case where this operation is inherited. In this case we
16480 have no easy means of determining the original tagged type for which
16481 the primitive was declared, so instead we now rely on
16482 Copy_Specification to use the Is_Controlling_Formal flag to determine
16483 which formals require type substitution.

16490 (No_Exception_Propagation) is set and in any case make the associated
16491 handler unsuitable as a target for a local raise statement.
16492 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16493 run-time subprogram CW_Membership by call to Build_CW_Membership.
16494 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16495 by a function call, a temporary must be created before expanding the
16496 Constructor_Call itself, to prevent out-of-order elaboration in the
16497 back-end when stack checking is enabled..

16577 (Non_VMS_Usage): Document that gnatstack accept project file switches.
16578 (GNATCmd): Update the B_Start variable if we are in a VMS environment.

16580 switches, and get the single attribute Switches from the stack package
16581 in a project file when calling gnatstack. Parse the -U flag for
16582 processing files belonging to all projects in the project tree.
16583 Remove all processing for command Setup

16623
16624 * mingw32.h (S2WSU): New macro to convert from a string to a
16625 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16626 standard 8bits encoding.
16627 (WS2SU): As above but converting from wide-sring to string.
16628 This is needed as it is necessary to have access to both versions in the
16629 runtime for the form parameter encoding support.
16630 This set of patch add support for the encoding form parameter.
16631 (S2WS): Improve implementation to handle cases where the filename is not
16632 UTF-8 encoded. In this case we default to using the current code page
16633 for the conversion.
16634
16635 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16636 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match
16637 the constants defined in adaint.h.
16638 (fopen): Add encoding parameter.
16639 (freopen): Idem.
16640
16641 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
16642 encoding. This is needed for the Reset routine (freopen low level-call).
16643
16644 * s-fileio.adb (Open): Decode encoding form parameter and set the
16645 corresponding encoding value into AFCB structure.
16646 (Reset): Pass the encoding value to freopen.
16647 (Close): Move the call to Lock_Task to the beginning of the procedure.

16680 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16681 __gnat_adjust_context_for_raise.
16682 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16683 implementation of floating point operations as native x86 targets.
16684 So the FPU should be initialized in the same way using finit. Fix
16685 floating point operations accuracy issues.
16686 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16687 member in struct sigaction, so as to avoid warning for incompatible
16688 pointer types.

16707 types that the type implements. List each of these interfaces when
16708 building the entry for the type.
16709 (Generate_Definition): Initialize component Def and Typ of new entry
16710 in table Xrefs, to avoid to have these components unitialized.

167542007-04-06 Robert Dewar <dewar@adacore.com>
16755
16756 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16757 it no longer destroys the contents of Name_Buffer or Name_Len and

16773 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16774 illegal in Ada 95, in cases where it is legal. Change the warnings to
16775 errors in other cases. Don't give the error unless the "not null"
16776 parses properly. Correct the source position at which the error occurs.
16777 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16778 P_Null_Exclusion, to suppress "not null" warnings.
16779 (P_Identifier_Declarations): Code cleanup. Removed unrequired label and
16780 associated goto statements.
16781
16782 * par-endh.adb (Pop_End_Context): Allow more flexibility in placement
16783 of END RECORD
16784

16786
16787 * par-ch6.adb (P_Mode): Check specifically for case of IN ACCESS

16820 Shared_Library_Minimum_Options,
16821 Shared_Library_Prefix, Shared_Library_Suffix, Symbolic_Link_Supported.

16831
16832 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16833 switches, without repetition of "eD". Make sure that last character of
16834 -gnatep= switch is not taken as -gnat switch character.
16835 Complete rewrite of circuit for handling saving compilation options
16836 Occasioned by need to support dot switchs for -gnatw, but cleans up
16837 things in general.
16838 -gnatX does not affect Ada_Version
16839 Include -gnatyA in -gnatg style switches
16840

16854 the default project path, initially done during elaboration of the
16855 package.
16856 If the prefix returned by Sdefault is null, get the prefix from a call
16857 to Executable_Prefix_Path.
16858 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16859 null.
16860
16861 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16862 canonical directory name to open the directory from which files are
16863 retrieved.
16864 (Record_Other_Sources): Idem.
16865 (Locate_Directory): Add the possibility to create automatically missing
16866 directories when Setup_Projects is True.

16868 Setup_Projects is True, for object dir, library dir, library ALI dir,
16869 library source copy dir and exec dir.
16870
16871 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older

16896
16897 * opt.ads: (Warn_On_Non_Local_Exception): New flag
16898 (Warn_On_Reverse_Bit_Order): New flag
16899 (Extensions_Allowed): Update the documentation.
16900 (Warn_On_Questionable_Missing_Parens): Now on by default

16904 -gnatq warnings are on by default
16905
169062007-04-06 Ed Falis <falis@adacore.com>
16907
16908 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16909 full word is no longer compared twice.
16910
169112007-04-06 Ed Schonberg <schonberg@adacore.com>
16912
16913 * sem_ch10.adb (Install_Limited_Context_Clauses.
16914 Expand_Limited_With_Clause): Use a new copy of selector name in the
16915 call to Make_With_Clause. This fixes the tree structure for ASIS
16916 purposes. Nothing is changed in the compiler behaviour.
16917 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16918 a package renaming.
16919 (Install_Limited_With_Clauses): Do not install non-limited view when it
16920 is still incomplete.
16921
169222007-04-06 Ed Schonberg <schonberg@adacore.com>
16923 Gary Dismukes <dismukes@adacore.com>
16924
16925 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16926 when capturing size information, instead of base type, which for a
16927 formal array type will be the unconstrained type.
16928 (Analyze_Formal_Object_Declaration): Add check for illegal default
16929 expressions for a formal in object of a limited type.
16930 (Instantiate_Object): Ditto.
16931 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16932 because they were defaulted in the formal package and no check applies
16933 to them.
16934 (Check_Formal_Package_Instance): Extend conformance check to other
16935 discrete types beyond Integer.
16936 (Process_Default): Copy directly the unmatched formal. A generic copy
16937 has already been performed in Analyze_Formal_Package.
16938 (Analyze_Associations): If a formal subprogram has no match, check for
16939 partial parametrization before looking for a default, to prevent
16940 spurious errors.
16941 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16942 not set the instantiation environment before analyzing the actuals.
16943 Fixes regression on 8515-003 with implementation of AI-133.
16944 Set_Instance_Env checks whether the generic unit is a predefined
16945 unit, in which case the instance must be analyzed with the latest Ada
16946 mode. This setting must take place after analysis of the actuals,
16947 because the actuals must be analyzed and frozen in the Ada mode extant
16948 outside of the current instantiation.
16949 (Save_Env, Restore_Env): Preserve and restore the configuration
16950 parameters so that predefined units can be compiled in the proper Ada
16951 mode.
16952 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16953 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16954 and Is_Abstract_Type.
16955 (Analyze_Formal_Package): For better error recovery, Add exception
16956 handler to catch Instantion_Error, which can be raised in
16957 Analyze_Associations

16960 Bob Duff <duff@adacore.com>
16961 Gary Dismukes <dismukes@adacore.com>
16962
16963 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16964 prefix type is a discriminated subtype of the type of the formal.
16965 (Analyze_Allocator): Collect all coextensions regardless of the context.
16966 Whether they can be allocated statically is determined in exp_ch4.
16967 (Analyze_Selected_Component): If the prefix is a limited view and the
16968 non-limited view is available, use the non-limited one.
16969 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16970 therefore illegal), suggest a qualified expression rather than a type
16971 conversion, because a type conversion would be illegal in this context.
16972 (Anayze_Allocator): Trace recursively all nested allocators so that all
16973 coextensions are on the corresponding list for the root. Do no mark
16974 coextensions if the root allocator is within a declaration for a stack-
16975 allocated object, because the access discriminants will be allocated on
16976 the stack as well.
16977 (Analyze_Call): Remove restriction on calls to limited functions for the
16978 cases of generic actuals for formal objects, defaults for formal objects
16979 and defaults for record components.
16980 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16981 element list. Their expansion is delayed until the enclosing allocator
16982 is processed and its finalization list constructed.
16983 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16984 for an operation with the given name among the primitive operations of
16985 the corresponding record type.
16986 (Analyze_Selected_Component): If the prefix is a task type that
16987 implements an interface, and there is no entry with the given name,
16988 check whether there is another primitive operation (e.g. a function)
16989 with that name.
16990 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16991 properly the indexing of a function call written in prefix form, where
16992 the function returns an array type, and all parameters of the function
16993 except the first have defaults.
16994 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16995 the original operands, rather than relocating them, for efficiency and
16996 to work properly when an operand is overloaded.
16997 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16998 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16999 (Analyze_Selected_Component): If the prefix is a private extension, only
17000 scan the visible components, not those of the full view.
17001 (Try_Primitive_Operation): If the operation is a procedure, collect all
17002 possible interpretations, as for a function, because in the presence of
17003 classwide parameters several primitive operations of the type can match
17004 the given arguments.
17005

17007 Robert Dewar <dewar@adacore.com>
17008
17009 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
17010 tag-indeterminate call to an abstract function, when the left-hand side
17011 is not classwide.
17012 (Analyze_Loop_Statement): Improve detection of infinite loops
17013
170142007-04-06 Ed Schonberg <schonberg@adacore.com>
17015 Thomas Quinot <quinot@adacore.com>
17016
17017 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
17018 out of Analyze_Package_Declaration, because processing must be applied
17019 to package bodies as well, for deferred constants completed by pragmas.
17020 (Analyze_Package_Declaration): When the package declaration being
17021 analyzed does not require an explicit body, call Check_Completion.
17022 (May_Need_Implicit_Body): An implicit body is required when a package
17023 spec contains the declaration of a remote access-to-classwide type.
17024 (Analyze_Package_Body): If the package contains RACWs, append the
17025 pending subprogram bodies generated by exp_dist at the end of the body.
17026 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
17027 Is_Abstract_Subprogram and Is_Abstract_Type.
17028 (Preserve_Full_Attributes): The full entity list is not an attribute
17029 that must be preserved from full to partial view.
17030
9e81dbc7
AS		 17031 * sem_dist.adb (Add_RAS_Dereference_TSS):
17032 Change primitive name to _Call so it cannot clash with any legal
17033 identifier, and be special-cased in Check_Completion.
17034 Mark the full view of the designated type for the RACW associated with
17035 a RAS as Comes_From_Source to get proper view switching when installing
17036 private declarations.
17037 Provite a placeholder nested package body along with the nested spec

17718 type_decl is properly set before calling the debug information writers.
17719 (write_record_type_debug_info): The heuristics which compute the
17720 alignment of a field in a variant record might not be accurate. Add a

18208
6f7f72f9 18209 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
70198b9f
AC		 18210 register in the final list objects containing class-wide interfaces;
18211 otherwise we incorrectly register the tag of the interface in the final
18212 list.
6f7f72f9
EB		 18213 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
18214 generate the wrapper if the parent primitive is abstract. This is
18215 required to report the correct error message.
18216 (Expand_N_Subtype_Indication): Do validity checks on range
70198b9f
AC		 18217 (Clean_Task_Names): If an initialization procedure includes a call to
18218 initialize a task (sub)component, indicate that the procedure will use
18219 the secondary stack.
18220 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
18221 compatibility for interfacing with CPP by default.
18222 (Expand_N_Object_Declaration): Only build an Adjust call when the
18223 object's type is a nonlimited controlled type.
18224 * exp_ch3.adb: Add with and use of Exp_Ch6.
18225 (Expand_N_Object_Declaration): Check for object initialization that is a
18226 call to build-in-place function and apply Make_Build_In_Place_Call_In_
18227 Object_Declaration to the call.
18228 (Freeze_Type): When the designated type of an RACW was not frozen at the
18229 point where the RACW was declared, validate the primitive operations
18230 with respect to E.2.2(14) when it finally is frozen.
18231 (Build_Initialization_Call,Expand_Record_Controller): Rename
18232 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18233 return-by-reference has no meaning in Ada 2005.
18234 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
18235 to register tag of the immediate ancestor interfaces in the
18236 run-time structure.
18237 (Init_Secondary_Tags): Moved to the specification to allow the
18238 initialization of extension aggregates with abstract interfaces.
18239 (Build_Master_Renaming): Make public, for use by function declarations
18240 whose return type is an anonymous access type.
18241 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18242 Insert_List_Before_And_Analyze after the generation of the specs
18243 associated with null procedures.
18244 (Expand_Tagged_Root): Update documentation in its specification.
18245 (Init_Secondary_Tags): Update documentation.
18246 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18247 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18248 then generate code to inherit the contents of the dispatch table
18249 directly from the ancestor.
18250 (Expand_Record_Controller): Insert controller component after tags of
18251 implemented interfaces.
18252 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
18253 create null procedure overridings when null procedures are inherited
18254 from interfaces.
18255 (Make_Null_Procedure_Specs): New procedure to generate null procedure
18256 declarations for overriding null primitives inherited from interfaces.
18257 (Is_Null_Interface_Procedure): New function in
18258 Make_Null_Procedure_Specs.
18259 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18260 immediate ancestor of a tagged type is an abstract interface type we
18261 must generate the specification of the predefined primitives associated
18262 with controlled types (because the dispatch table of the ancestor is
18263 null and hence these entries cannot be inherited). This is required to
18264 elaborate well the dispatch table.

6f7f72f9
EB		 18271
18272 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
70198b9f 18273 conversion.
6f7f72f9 18274 (Expand_N_In): Do validity checks on range
70198b9f
AC		 18275 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
18276 (Expand_N_Allocator): For "new T", if the object is constrained by
18277 discriminant defaults, allocate the right amount of memory, rather than
18278 the maximum for type T.
18279 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18280 when the allocator is initialized by a build-in-place call, since the
18281 allocator is already rewritten as a reference to the function result,
18282 and this prevents an unwanted duplication of the function call.
18283 Add with and use of Exp_Ch6.
18284 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18285 is a call to build-in-place function and apply
18286 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18287 untagged designated types).
18288 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18289 optimization if source or target is biased.
18290 (Expand_N_Allocator): Add comments for case of an allocator within a
18291 function that returns an anonymous access type designating tasks.
18292 (Expand_N_Allocator): apply discriminant checks for access
18293 discriminants of anonymous access types (AI-402, AI-416)

18299
18300 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
18301
6f7f72f9 18302 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
70198b9f
AC		 18303 (Expand_N_Assignment_Statement): Call
18304 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
18305 build-in-place function call. Currently, this can happen only for
18306 assignments that come from aggregates.
18307 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18308 in order to alleviate the upward compatibility introduced by AI-318.
18309 (Expand_N_Extended_Return_Statement): Add support for handling the
18310 return object as a build-in-place result.
18311 (Expand_Non_Function_Return): Implement simple return statements nested
18312 within an extended return.
18313 (Enable_New_Return_Processing): Turn on the new processing of return
18314 statements.
18315 (Expand_Non_Function_Return): For a return within an extended return,
18316 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18317 (Expand_N_Extended_Return_Statement): Implement AI-318
18318 (Expand_Simple_Function_Return): Ditto.
18319 (Expand_N_If_Statement): Handle new -gnatwt warning
18320 (Expand_N_Case_Statement): Handle new -gnatwt warning
18321 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18322 a protected object.
18323 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18324 validity checking of assignments to elementary record components.
18325 (Expand_N_Return_Statement): return Class Wide types on the secondary
18326 stack independantly of their controlled status since with HIE runtimes,
18327 class wide types are not potentially controlled anymore.
18328
18329 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18330 node kind.
18331
18332 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18333 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18334 it expects a block, procedure, or task. The return statement will get
18335 turned into a block, and Expand_Cleanup_Actions will happen then.
18336
183372006-10-31 Robert Dewar <dewar@adacore.com>
18338 Ed Schonberg <schonberg@adacore.com>
18339 Bob Duff <duff@adacore.com>
18340 Gary Dismukes <dismukes@adacore.com>
18341
18342 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18343 capability.
18344 (Expand_Inlined_Call): Tagged types are by-reference types, and
18345 therefore should be replaced by a renaming declaration in the expanded
18346 body, as is done for limited types.
18347 (Expand_Call): If this is a call to a function with dispatching access
18348 result, propagate tag from context.
18349 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18350 CPP by default.
18351 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18352 build-in-place when the right-hand side of an assignment is a
18353 build-in-place function call.
18354 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18355 of the explicit dereference of the allocator to the result subtype of
18356 the build-in-place function. This is needed to satisfy type checking
18357 in cases where the caller's return object is created by an allocator for
18358 a class-wide access type and the type named in the allocator is a
18359 specific type.
18360 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18361 conversion of the reference to the declared object to the result subtype
18362 of the build-in-place function. This is needed to satisfy type checking
18363 in cases where the declared object has a class-wide type. Also, in the
18364 class-wide case, change the type of the object entity to the specific
18365 result subtype of the function, to avoid passing a class-wide object
18366 without explicit initialization to the back end.
18367 (Register_Interface_DT_Entry): Moved outside the body of
18368 Freeze_Subprogram because this routine is now public; it is called from
18369 Check_Dispatching_Overriding to handle late overriding of abstract
18370 interface primitives.
18371 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18372 adding an implicit access actual on a call to a build-in-place function.
18373 (Expand_Actuals): Test for an actual parameter that is a call to a
18374 build-in-place function and apply
18375 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18376 (Is_Build_In_Place_Function): New function to determine whether an
18377 entity is a function whose calls should be handled as build-in-place.
18378 (Is_Build_In_Place_Function_Call): New function to determine whether an
18379 expression is a function call that should handled as build-in-place.
18380 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18381 calls to build-in-place functions as the initialization of an allocator.
18382 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18383 handling calls to build-in-place functions in contexts that do not
18384 involve init of a separate object (for example, actuals of subprogram
18385 calls).
18386 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18387 handling calls to build-in-place functions as the initialization of an
18388 object declaration.
18389 (Detect_Infinite_Recursion): Add explicit parameter Process to
18390 instantiation of Traverse_Body to avoid unreferenced warning.
18391 (Check_Overriding_Inherited_Interfaces): Removed.
18392 (Register_Interface_DT_Entry): Code cleanup.
18393 (Register_Predefined_DT_Entry): Code cleanup.
18394 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18395 inlined statements if within a transient scope.
18396 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18397 formal parameters with occurrences of actuals in inlined body, establish
18398 visibility on the proper view of the actual's subtype for the body's
18399 context.
18400 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18401 compatibility mode and we have an imported CPP subprogram because
18402 for now we assume that imported CPP primitives correspond with
18403 objects whose constructor is in the CPP side (and therefore we
18404 don't need to generate code to register them in the dispatch table).
18405 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18406 aligned selected component.
18407 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18408 the actual of an in-mode parameter is a type conversion.
18409 (Expand_Actuals): If the call does not come from source and the actual
18410 is potentially misaligned, let gigi handle it rather than rejecting the
18411 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18412 Class Wide types as returning by reference independantly of their
18413 controlled status since with HIE runtimes class wide types are not
18414 potentially controlled anymore.

70198b9f
AC		 18419 references that are private components of the protected object.
18420 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
18421 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18422 instantiation to deal with warnings.
18423 (Initialize_Protection): If expression for priority is non-static, use
18424 System_Priority as its expected type, in case the expression has not
18425 been analyzed yet.
18426
184272006-10-31 Robert Dewar <dewar@adacore.com>
18428
18429 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18430 initialization of Homonym_Len.
18431 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18432 names from fully qualified name. Fixes problem of duplicate
18433 external names differing only in the presence of such a block name.
18434

EB		 18437
18438 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
70198b9f
AC		 18439 subprogram Ids, even if they are not yet assigned.
18440 (Build_Subprogram_Id): It is now this function that will take care of
18441 calling Assign_Subprogram_Ids if necessary.
18442 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18443 should be done only once they are assigned.
18444 (Build_From_Any_Function, case of tagged types): Add missing call to
18445 Allocate_Buffer.
18446 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18447 type for an RACW type.
18448 (Add_RACW_Features): When processing an RACW declaration for which the
18449 designated type is already frozen, enforce E.2.2(14) rules immediately.
18450 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18451 special reordering of controlling formals.
18452
18453 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18454 associated stub type for an RACW type.
18455
184562006-10-31 Ed Schonberg <schonberg@adacore.com>
18457
18458 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18459 fixed-point operations in an integer context, i.e. as operands of a
18460 conversion to an integer type, indicate that result must be rounded.
18461
184622006-10-31 Robert Dewar <dewar@adacore.com>
18463
18464 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18465 cases, pass the encoding method, since it is now required by the run
18466 time.
18467
18468 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18469 assumption that Str'First = 1.
18470 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18471 it on to the Value_Wide_Wide_Character call.
18472 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18473 properly handles a string of the form quote-encoded_wide_char-quote.
18474
18475 * s-wchcnv.adb: Minor reformatting
18476
184772006-10-31 Javier Miranda <miranda@adacore.com>
6f7f72f9 18478
70198b9f
AC		 18479 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18480 run-time membership test to ensure that the constructed object
18481 implements the target abstract interface.
18482
184832006-10-31 Robert Dewar <dewar@adacore.com>
18484
18485 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18486 Machine_Attribute pragma internally to implement the user pragma.
18487 Add processing for pragma Interface so that it is now completely
18488 equivalent to pragma Import.
18489
18490 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18491 so that it can be applied to all entities, including record components
18492 and enumeration literals.
18493 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18494 priority ranges are correct, verify compatibility against task
18495 dispatching and locking policies, and if everything is correct an entry
18496 is added to the table containing priority specific dispatching entries
18497 for this compilation unit.
18498 (Delay_Config_Pragma_Analyze): Delay processing
18499 Priority_Specific_Dispatching pragmas because when processing the
18500 pragma we need to access run-time data, such as the range of
18501 System.Any_Priority.
18502 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18503 Allow pragma Unreferenced as a context item
18504 Add pragma Preelaborable_Initialization
18505 (Analyze_Pragma, case Interface): Interface is extended so that it is

18523 in Ada 2005.
18524 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18525 type of the function containing a return statement, because the
18526 Return_Type field was removed. We now use the Return_Applies_To field.
18527
6f7f72f9 18528 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
70198b9f
AC		 18529 (Build_Task_Image_Decl): If procedure is not called from an
18530 initialization procedure, indicate that function that builds task name
18531 uses the sec. stack. Otherwise the enclosing initialization procedure
18532 will carry the indication.
18533 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18534 N_Object_Declaration instead.
18535 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18536 conditional dead code killed, and change implementation accordingly.
18537 (Insert_Actions): Add N_Return_Object_Declaration case.
18538 Correct comment to mention N_Extension_Aggregate node.
18539 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18540 attempts to save information for global variables which cannot be
18541 safely tracked.
18542 (Get_Current_Value_Condition): Handle conditions the other way round
18543 (constant on left). Also handle right operand of AND and AND THEN
18544 (Set_Current_Value_Condition): Corresponding changes
18545 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18546 (Get_Current_Value_Condition): Handle simple boolean operands
18547 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18548 (Get_Current_Value_Condition): If the variable reference is within an
18549 if-statement, does not appear in the list of then_statments, and does
18550 not come from source, treat it as being at unknown location.
18551 (Get_Current_Value_Condition): Enhance to allow while statements to be
18552 processed as well as if statements.
18553 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18554 come from source.
18555 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18556 of loop. This is safe now that we fixed Kill_Current_Values.
18557 (OK_To_Do_Constant_Replacement): Check whether current scope is
18558 Standard, before examining outer scopes.

185602006-10-31 Vincent Celier <celier@adacore.com>
18561
18562 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18563 When True, apply VMS treatment to children of packages A, G, I and S.

18571 * freeze.adb: Add handling of Last_Assignment field
18572 (Warn_Overlay): Supply missing continuation marks in error msgs
18573 (Freeze_Entity): Add check for Preelaborable_Initialization
18574
18575 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18576

18591 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18592 exception handler.
18593 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18594 use clauses, to avoid messages on packages used to qualify, and also
18595 to avoid messages from obsolescent units.
18596 (Warn_On_Useless_Assignments): Don't generate messages for imported
18597 and exported variables.
18598 (Warn_On_Useless_Assignments): New procedure
18599 (Output_Obsolescent_Entity_Warnings): New procedure
18600 (Check_Code_Statement): New procedure
18601
6f7f72f9 18602 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
70198b9f
AC		 18603 Change name Is_Ada_2005 to Is_Ada_2005_Only
18604 (Last_Assignment): New field for useless assignment warning
18605
186062006-10-31 Olivier Hainque <hainque@adacore.com>
18607
18608 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18609 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18610
186112006-10-31 Bob Duff <duff@adacore.com>
18612 Robert Dewar <dewar@adacore.com>
18613 Ed Schonberg <schonberg@adacore.com>
18614
18615 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18616 Ada 95 mode, because it violates the new rules for AI-318.
18617
18618 * g-awk.ads: Use overloaded subprograms in every case where we used to
18619 have a default of Current_Session. This makes the code closer to be
18620 correct for both Ada 95 and 2005.
18621
18622 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18623 code, relying on the fact that the compiler generates a warning
18624 instead of an error in -gnatg mode.
18625
18626 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18627 E_Return_Statement entity kind.
18628 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18629
18630 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18631 report an error if the reserved word abstract has been previously found.
18632 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
6f7f72f9
EB		 18633
18634 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
70198b9f
AC		 18635 parenthesized range attribute usage
18636 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18637
18638 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18639 in the syntax for extended_return_statement. This is not in the latest
18640 RM, but the ARG is expected to issue an AI allowing this.
18641 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18642 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18643 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18644 P_Return_Statement): Parse the new syntax for extended_return_statement.
18645
18646 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18647 Output_End_Missing): Add error-recovery code for the new
18648 extended_return_statement syntax; that is, the new E_Return entry on
18649 the scope stack.
18650
18651 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18652 limited to nonlimited, because otherwise we violate the new Ada 2005
18653 rules about returning limited types in function Create_AST_Handler in
18654 s-asthan.adb.
18655
18656 * sem.adb (Analyze): Add cases for new node kinds
18657 N_Extended_Return_Statement and N_Return_Object_Declaration.
18658
18659 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18660 type is in the same category as type of context before applying check,
18661 to prevent anomalies in instantiations.
18662 (Resolve_Aggregate): Remove test for limited components in aggregates.
18663 It's unnecessary in Ada 95, because if it has limited components, then
18664 it must be limited. It's wrong in Ada 2005, because limited aggregates
18665 are now allowed.
18666 (Resolve_Record_Aggregate): Move check for limited types later, because
18667 OK_For_Limited_Init requires its argument to have been resolved.
18668 (Get_Value): When copying the component default expression for a
18669 defaulted association in an aggregate, use the sloc of the aggregate
18670 and not that of the original expression, to prevent spurious
18671 elaboration errors, when the expression includes function calls.
18672 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18673 were missing. We also didn't handle qualified expressions. Now also
18674 allow function calls. Use new common routine OK_For_Limited_Init.
18675 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18676 with space can upper case letter).
18677
6f7f72f9 18678 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
70198b9f 18679 Has_Static_Discriminants flag
6f7f72f9
EB		 18680 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18681 type with discriminants.
18682 (Process_Range_Expr_In_Decl): Do validity checks on range
70198b9f
AC		 18683 (Build_Discriminant_Constraints): Use updated form of
18684 Denotes_Discriminant.
18685 (Process_Subtype): If the subtype is a private subtype whose full view
18686 is a concurrent subtype, introduce an itype reference to prevent scope
18687 anomalies in gigi.
18688 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18689 Record_Type_Declaration): The functionality of the subprograms
18690 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18691 is now performed by a single routine.
18692 (Build_Derived_Record_Type): If the type definition includes an explicit
18693 indication of limitedness, then the type must be marked as limited here
18694 to ensure that any access discriminants will not be treated as having
18695 a local anonymous access type.
18696 (Check_Abstract_Overriding): Issue a detailed error message when an
18697 abstract subprogram was not overridden due to incorrect mode of its
18698 first parameter.
18699 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18700 synchronized private extension declarations. Verify that the ancestor is
18701 a limited or synchronized interface or in the generic case, the ancestor
18702 is a tagged limited type or synchronized interface and all progenitors
18703 are either limited or synchronized interfaces.
18704 Derived_Type_Declaration): Check for presence of private extension when
18705 dealing with synchronized formal derived types.
18706 Process_Full_View): Enchance the check done on the usage of "limited" by
18707 testing whether the private view is synchronized.
18708 Verify that a synchronized private view is completed by a protected or
18709 task type.
18710 (OK_For_Limited_Init_In_05): New function.
18711 (Analyze_Object_Declaration): Move check for limited types later,
18712 because OK_For_Limited_Init requires its argument to have been resolved.
18713 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18714 in order to alleviate the upward compatibility introduced by AI-318.
18715 (Constrain_Corresponding_Record): If the constraint is for a component
18716 subtype, mark the itype as frozen, to avoid out-of-scope references to
18717 discriminants in the back-end.
18718 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18719 this subprogram against wrong sources.
18720 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18721 discriminant of limited type completed with a protected type, when the
18722 discriminant is used to constrain a private component of the type, and
18723 expansion is disabled.
18724 (Find_Type_Of_Object): Do not treat a return subtype that is an
18725 anonymous subtype as a local_anonymous_type, because its accessibility
18726 level is the return type of the enclosing function.
18727 (Check_Initialization): In -gnatg mode, turn the error "cannot
18728 initialize entities of limited type" into a warning.
18729 (OK_For_Limited_Init): Return true for generated nodes, since it
18730 sometimes violates the legality rules.
18731 (Make_Incomplete_Declaration): If the type for which an incomplete
18732 declaration is created happens to be the currently visible entity,
18733 preserve the homonym chain when removing it from visibility.
18734 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18735 inherited subprograms.
18736 (Access_Definition): If this is an access to function that is the return
18737 type of an access_to_function definition, context is a type declaration
18738 and the scope of the anonymous type is the current one.
18739 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18740 incomplete subtype to the set of private dependents of the original
18741 incomplete type.
18742 (Constrain_Discriminated_Type): Emit an error message whenever an
18743 incomplete subtype is being constrained.
18744 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18745 corresponding subtype of the full view of the original incomplete type.
18746 (Check_Incomplete): Properly detect invalid usage of incomplete types
18747 and subtypes.
18748

18760 Robert Dewar <dewar@adacore.com>
18761
18762 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18763 handling executable extension manually and duplicating code.
18764
18765 * make.adb: Implement new -S switch
18766 (Gnatmake): Use new function Osint.Executable_Name instead
18767 of handling executable extension manually.
18768
18769 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18770 is specified, the executable name ends with this suffix.
18771 Take advantage of Osint.Executable_Name instead of duplicating code.
18772
18773 * switch-m.adb: Recognize new gnatmake -S switch
18774
18775 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18776 variable.
18777 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18778 available.

18780 * makeusg.adb: Add line for gnatmake -S switch
18781
187822006-10-31 Vincent Celier <celier@adacore.com>
18783
18784 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18785 call it with -static-libgcc, as there are some platforms, such as
18786 Darwin, where one of these two switches is compulsory to link.
18787
187882006-10-31 Vincent Celier <celier@adacore.com>
6f7f72f9 18789
70198b9f
AC		 18790 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18791 instead of ADA_PROJECT_PATH, for the project path.
18792 (Gnatls): When displaying the project path directories, use host dir
18793 specs.
18794
18795 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18796 names in the project path, as absolute paths may correspond to
18797 multi-valued VMS logical names.
18798
187992006-10-31 Vincent Celier <celier@adacore.com>
18800
18801 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18802 absolute path name.
18803 (Locate_Regular_File): Ditto
18804 (Change_Dir): Remove, no longer used
18805 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18806 on Windows. Get it calling Get_Current_Dir.
18807 (OpenVMS): Remove imported boolean, no longer needed.
18808 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18809 (Pid_To_Integer): New function to convert a Process_Id to Integer
18810
188112006-10-31 Thomas Quinot <quinot@adacore.com>
18812
18813 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18814 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18815 to No_Socket.
18816 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18817 W_Sig_Socket.
18818

18829
6f7f72f9
EB		 18830 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18831 variant records
18832 (Layout_Variant_Record): Retrieve the discriminants from the entity
70198b9f
AC		 18833 rather than from the type definition, because in the case of a full
18834 type for a private type we need to take the discriminants from the
18835 partial view.
6f7f72f9
EB		 18836 (Layout_Component_List): When applying the Max operator to variants with
18837 a nonstatic size, check whether either operand is static and scale that
18838 operand from bits to storage units before applying Max.
70198b9f
AC		 18839 (Layout_Type): In VMS, if a C-convention access type has no explicit
18840 size clause (and does not inherit one in the case of a derived type),
18841 then the size is reset to 32 from 64.
18842
188432006-10-31 Vincent Celier <celier@adacore.com>
18844
18845 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18846 its file has already been loaded, according to the unit being loaded,
18847 not to the current value of Multiple_Unit_Index.
18848
188492006-10-31 Thomas Quinot <quinot@adacore.com>
18850 Eric Botcazou <ebotcazou@adacore.com>

18852
18853 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18854 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18855 possible.

18858 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18859 a-calend-mingw.adb version.
18860
6f7f72f9 18861 * Makefile.rtl: Added s-dsaser.
70198b9f
AC		 18862 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18863 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18864 Ada.Dispatching.Round_Robin.
18865 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18866
18867 * Make-lang.in: Remove all references to gt-ada-decl.h.
18868 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18869 sources.
18870 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18871 Update dependencies.
18872
18873 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18874
188752006-10-31 Vincent Celier <celier@adacore.com>
18876
18877 * mlib-utl.adb (Initialized): Remove, no longer used
18878 (Initialize): Remove, no longer used
18879 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18880 if there is one, the archive indexer. Fail if the archive builder cannot
18881 be found.
18882 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18883 be found.
18884
188852006-10-31 Ed Schonberg <schonberg@adacore.com>
18886
18887 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18888 Process_Body_Clauses): If the context of a body includes a use clause
18889 for P.Q then a with_clause for P in the same body is not redundant,
18890 even if the spec also has a with_clause on P.
18891 Add missing continuation mark to error msg
18892 (Build_Limited_Views): A limited view of a type is tagged if its
18893 declaration includes a record extension.
18894 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18895 node, even if the subunit has errors. This avoids malfunction by
18896 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18897 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18898 generation of obsolescent messages for with statements (cannot do
18899 this too early, or we cannot implement avoiding the messages in the
18900 case of obsolescent units withing obsolescent units).
18901 (Install_Siblings): If the with_clause is on a remote descendant of
18902 an ancestor of the current compilation unit, find whether there is
18903 a sibling child unit that is immediately visible.
18904 (Remove_Private_With_Clauses): New procedure, invoked after completing
18905 the analysis of the private part of a nested package, to remove from
18906 visibility the private with_clauses of the enclosing package
18907 declaration.
18908 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18909 now centralized in Generate_Reference.
18910 (Install_Limited_Context_Clauses): Remove superfluous error
18911 message associated with unlimited view visible through use
18912 and renamings. In addition, at the point in which the error
18913 is reported, we add the backslash to the text of the error
18914 to ensure that it is reported as a single error message.
18915 Use new // insertion for some continuation messages
18916 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18917 to create implicit with_clause for parent unit mentioned in original
18918 limited_with_clause.
18919 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18920 unit is a child unit. For ASIS queries.
18921 (Analyze_Subunit): If the subunit appears within a child unit, make all
18922 ancestor child units directly visible again.
18923

18932 (P_Formal_Type_Definition, P_Formal_Derived_Type_Definition): Add
18933 support for synchronized derived type definitions.
18934 Add the new actual Abstract_Present to every call to
18935 P_Interface_Type_Definition.
18936 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18937 a formal object declaration with an access definition or a subtype mark
18938 with a null exclusion.
18939 (P_Generic_Association): Handle association with box, and others_choice
18940 with box, to support Ada 2005 partially parametrized formal packages.
18941

70198b9f
AC		 18945 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18946 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18947 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18948 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18949 private extensions.
18950 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18951 to P_Interface_Type_Definition.
18952 (P_Interface_Type_Definition): Addition of one formal to report an error
18953 if the reserved word abstract has been previously found.
18954 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18955 object renaming declaration with an access definition or subtype mark
18956 with a possible null exclusion.
18957

189642006-10-31 Vincent Celier <celier@adacore.com>
18965
18966 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
18967 unknown attribute in unknown package or in package that does not need
18968 to be checked.
18969 (Parse_Package_Declaration): Do not issue warning for unknown package in
18970 quiet output.
18971
189722006-10-31 Vincent Celier <celier@adacore.com>
18973
18974 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18975 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18976 Packages_To_Check.
18977
189782006-10-31 Vincent Celier <celier@adacore.com>
18979
18980 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18981 on VMS, change "__" to '.' before checking the name.
18982 (Record_Ada_Source): Always add the source file name in the list of
18983 of sources, even if it is not the first time, as it is for another
18984 source index.
18985 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18986 dot, instead of replacing only the first '_'.
18987
18988 * prj-part.adb (Parse): Convert project file path to canonical form
18989
18990 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18991 extended, the project id of the project extending it is recorded in its
18992 data, even when it has already been processed as an imported project.
18993
189942006-10-31 Robert Dewar <dewar@adacore.com>

19000 Robert Dewar <dewar@adacore.com>
19001
19002 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
19003 only a restriction warning is active for the given restriction. This is
19004 desirable because we do not want to modify code in the case where only
19005 a warning is set.
19006 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
19007 causes overriding of real restrictions.

19038 properly an attempt to apply Unchecked_Access to a protected operation.
19039 (OK_Self_Reference): New subprogram to check the legality of an access
19040 attribute whose prefix is the type of an enclosing aggregate.
19041 Generalizes previous mechanism to handle attribute references nested
19042 arbitrarily deep within the aggregate.
19043 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19044 can appear in an aggregate if this is a default-initialized aggregate
19045 for a self-referential type.
19046 (Resolve_Attribute, case Access): Ditto.
19047 Add support for new implementation defined attribute Stub_Type.
19048 (Eval_Attribute, case Attribute_Stub_Type): New case.
19049 (Analyze_Attribute, case Attribute_Stub_Type): New case.
19050 (Stream_Attribute_Available): Implement using new subprogram from
19051 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
19052 Has_Specified_Stream_Attribute flag.
19053 Disallow Storage_Size and Storage_Pool for access to subprogram
19054 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19055 access types of return subtypes in extended return statements. Remove
19056 accessibility checks on anonymous access types when Unchecked_Access is
19057 used.

19059 a class-wide interface to a tagged type.
19060 Add support for the attribute Priority.
19061 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19062 whether the designated type is discriminated with a constrained partial
19063 view and require static matching in that case.
19064 Add local variable Des_Btyp. The Designated_Type
19065 of an access to incomplete subtype is either its non-limited view if
19066 coming from a limited with or its etype if regular incomplete subtype.
19067
19068 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19069 Fix predicate to identify and allow cases of (expander-generated)
19070 references to tag of designated object of a RACW.
19071 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19072 non-static, and therefore cannot appear as a primary in a preelaborable
19073 package.
19074 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
19075 Has_Read_Write_Attributes.
19076 (Has_Read_Write_Attributes): Reimplement in termes of
19077 Has_Stream_Attribute_Definition.
19078 (Missing_Read_Write_Attributes): When checking component types in a
19079 record, unconditionally call Missing_Read_Write_Attributes recursively
19080 (remove guard checking for Is_Record_Type / Is_Access_Type).

AC		 19094 that has been constant-folded, preserve information of original tree,
19095 for ASIS uses.
19096 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
19097 generated private extension declaration if the formal derived type is
19098 synchronized. Carry synchronized present over to the generated private
19099 extension.
19100 (Validate_Derived_Type_Instance): Ensure that the actual of a
19101 synchronized formal derived type is a synchronized tagged type.
19102 (Instantiate_Formal_Package): When creating the instantiation used to
19103 validate the actual package of a formal declared without a box, check
19104 whether the formal itself depends on a prior actual.
19105 (Instantiate_Formal_Subprogram): Create new entities for the defining
19106 identifiers of the formals in the renaming declaration, for ASIS use.
19107 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19108 a renaming declaration or a subtype declaration for an actual in an
19109 instance, capture location information of declaration in generic, for
19110 ASIS use.
19111 (Instantiate_Formal_Package): Add comments on needed additional tests.
19112 AI-317 (partial parametrization) is fully implemented.
19113 (Validate_Private_Type_Instance): Add check for actual which
19114 must have preelaborable initialization
19115 Use new // insertion for some continuation messages
19116 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19117 Default_Expression. Add type retrieval when the declaration has an
19118 access definition. Update premature usage of incomplete type check.
19119 (Check_Access_Definition): New subsidiary routine. Check whether the
19120 current compilation version is Ada 05 and the supplied node has an
19121 access definition.
19122 (Instantiate object): Alphabetize local variables. Handle the creation
19123 of new renaming declarations with respect to the kind of definition
19124 used - either an access definition or a subtype mark. Guard against
19125 unnecessary error message in the context of anonymous access types after
19126 they have been resolved. Add check for required null exclusion in a
19127 formal object declaration.
19128 (Switch_View): A private subtype of a non-private type needs to be
19129 switched (the base type can have been switched without its private
19130 dependents because of the last branch of Check_Private_View.
19131 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19132 value from BT.
19133 (Instantiate_Type): Emit an error message whenever a class-wide type of
19134 a tagged incomplete type is used as a generic actual.
19135 (Find_Actual_Type): Extend routine to handle a component type in a child
19136 unit that is imported from a formal package in a parent.
19137 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19138 agree on constrainedness, rather than checking against ultimate ancestor
19139 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19140 generic body, for navigation purposes.

19146 type.
19147 (New_Stream_Subprogram): When processing an attribute definition clause
19148 for a stream-oriented subprogram, record an entity node occurring at
19149 the point of clause to use for checking the visibility of the clause,
19150 as defined by 8.3(23) as amended by AI-195.
19151 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19152 New_Stream_Function and New_Stream_Procedure.

19160
19161 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19162 generate the same errors compiling under -gnatc.
19163 (Try_Object_Operation): If no candidate interpretation succeeds, but
19164 there is at least one primitive operation with the right name, report
19165 error in call rather than on a malformed selected component.
19166 (Analyze_Selected_Component): If the prefix is an incomplete type from
19167 a limited view, and the full view is available, use the full view to
19168 determine whether this is a prefixed call to a primitive operation.
19169 (Operator_Check): Verify that a candidate interpretation is a binary
19170 operation before checking the type of its second formal.
19171 (Analyze_Call): Add additional warnings for function call contexts not
19172 yet supported.
19173 (Analyze_Allocator): Move the check for "initialization not allowed for
19174 limited types" after analyzing the expression. This is necessary,
19175 because OK_For_Limited_Init looks at the structure of the expression.
19176 Before analysis, we don't necessarily know what sort of expression it
19177 is. For example, we don't know whether F(X) is a function call or an
19178 indexed component; the former is legal in Ada 2005; the latter is not.
19179 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19180 were missing. We also didn't handle qualified expressions. Now also
19181 allow function calls. Use new common routine OK_For_Limited_Init.
19182 (Analyze_Type_Conversion): Do not perform some legality checks in an
19183 instance, because the error message will be redundant or spurious.
19184 (Analyze_Overloaded_Selected_Component): Do not do style check when
19185 setting an entity, since we do not know it is the right entity yet.
19186 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19187 (Analyze_Overloaded_Selected_Component): Same change
19188 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19189 since regular incomplete subtypes are transformed into corresponding
19190 subtypes of their full views.
19191 (Complete_Object_Operation): Treat name of transformed subprogram call
19192 as coming from source, for browsing purposes.
19193 (Try_Primitive_Operation): If formal is an access parameter, compare
19194 with base type of object to determine whether it is a primitive
19195 operation.
19196 (Operator_Check): If no interpretation of the operator matches, check
19197 whether a use clause on any candidate might make the operation legal.
19198 (Try_Class_Wide_Operation): Check whether the first parameter is an
19199 access type whose designated type is class-wide.

19207 Add \\ to some continuation messages
19208 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19209 (Process_Bounds): If the bounds are integer literals that result from
19210 constant-folding, and they carry a user-defined type, preserve that type
19211 rather than treating this as an integer range.
19212 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
19213 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
19214 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
19215 left hand side of assignment.
19216 (Analyze_Assignment): Add suport to manage assigments to the attribute
19217 priority of a protected object.
19218 (Check_Possible_Current_Value_Condition): Allow fully qualified names
19219 not just identifiers.
19220 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
19221 or AND THEN for possible tracking.
19222 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
19223 case of while loops so we can track values in the loop body.

AC		 19229 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19230 procedure cannot be a protected operation (it is a basic_declaration,
19231 not a subprogram_declaration).
19232 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19233 Subp. Add logic for entry processing.
19234 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
19235 Determine whether an entry or subprogram of a protected or task type
19236 override an inherited primitive of an implemented interface.
19237 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
19238 Update the actual used in calls to Check_Overriding_Indicator.

19242 Is_Formal.
19243 Add -gnatd.l --Use Ada 95 semantics for limited function returns,

19246 Extra_Formals field.
19247 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19248 pass new parameters. Add support for adding the new extra access formal
19249 for functions whose calls are treated as build-in-place.
19250 (Analyze_A_Return_Statement): Correct casing in error message.
19251 Move Pop_Scope to after Analyze_Function_Return, because an extended
19252 return statement really is a full-fledged scope. Otherwise, visibility
19253 doesn't work right. Correct use of "\" for continuation messages.
19254 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19255 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19256 the node doesn't get properly marked as analyzed.
19257 (Analyze_Subprogram_Body): If subprogram is a function that returns
19258 an anonymous access type that denotes a task, build a Master Entity
19259 for it.
19260 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19261 proper usage of null exclusion in a result definition.
19262 (Process_Formals): Code cleanup and new error message.
19263 (Process_Formals): Detect incorrect application of null exclusion to
19264 non-access types.
19265 (Conforming_Types): Handle conformance between [sub]types and itypes
19266 generated for entities that have null exclusions applied to them.
19267 (Maybe_Primitive_Operation): Add an additional type retrieval when the
19268 base type is an access subtype. This case arrises with null exclusions.
19269 (New_Overloaded_Entity): Do not remove the overriden entity from the
19270 homonym chain if it corresponds with an abstract interface primitive.
19271 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19272 call to the synthesized predicate Is_Incomplete_Type.
19273 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19274 primitives.
19275 (Analyze_Subprogram_Declaration): Check that abstract interface
19276 primitives are abstract or null.
19277 (Analyze_Subprogram_Specification): Remove previous check for abstract
19278 interfaces because it was not complete.

19287 may have only a limited view.
19288 (Analyze_Package_Specification): For the private part of a nested
19289 package, install private_with_clauses of enclosing compilation unit if
19290 we are in its visible part.
19291 (Declare_Inherited_Private_Subprograms): Complete barrier
19292 to ensure that the primitive operation has an alias to some parent
19293 primitive. This is now required because, after the changes done for the
19294 implementation of abstract interfaces, the contents of the list of
19295 primitives has entities whose alias attribute references entities of
19296 such list of primitives.
19297 (Analyze_Package_Specification): Simplify code that handles parent units

19330 profile of a renamed subprogram have required null exclusions when
19331 their counterparts of the renaming already impose them.

20988 procedure spec and body of the Offset_To_Top function that is generated
20989 when the parent of a type with discriminants has secondary dispatch
20990 tables.
20991 (Init_Secondary_Tags): Handle the case in which the parent of the type
20992 containing secondary dispatch tables has discriminants to generate the

21003 operations or the parent type.
21004 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
21005 functionality of Set_Prim_Op_Address but applied to predefined primitive
21006 operations.

21008 (Displace): If the Offset_To_Top value is not static then call the
21009 function generated by the expander to get such value; otherwise use
21010 the value stored in the table of interfaces.
21011 (Offset_To_Top): The type of the actual has been changed to Address to
21012 give the correct support to tagged types with discriminants. In this
21013 case this value is stored just immediately after the tag field.
21014 (Set_Offset_To_Top): Two new formals have been added to indicate if the
21015 offset_to_top value is static and hence pass this value to the run-time
21016 to store it in the table of interfaces, or else if this value is dynamic
21017 and then pass to the run-time the address of a function that is
21018 generated by the expander to provide this value for each object of the
21019 type.

21031 Make_Adjust_Call done for a newly-allocated object.
21032
21033 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
21034 in a subprogram are wrapped in a cleanup block, indicate that the
21035 subprogram contains an inner block with an exception handler.
21036 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
21037 Adjust call is for a newly-allocated object. In that case we must not
21038 assume that the finalization list chain pointers are correct (since they
21039 come from a bit-for-bit copy of the original object's pointers) so if
21040 the attach level would otherwise be zero (no change), we set it to 4
21041 instead to cause the pointers to be reset to null.
21042
21043 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning

21058 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21059 return unconstrained arrays.
21060 Update comments.
21061 (Expand_Call): An indirect call through an access parameter of a
21062 protected operation is not a protected call.
21063 Add circuit to raise CE in Ada 2005 mode following call
21064 to Raise_Exception.
21065 (Register_DT_Entry): Do nothing if
21066 the run-time does not give support to abstract interfaces.
21067 (Freeze_Subprogram): In case of dispatching operations, do not generate
21068 code to register the operation in the dispatch table if the source
21069 is compiled with No_Dispatching_Calls.
21070 (Register_Predefined_DT_Entry): Generate code that calls the new
21071 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21072 Set_Prim_Op_Address.
21073
21074 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21075 on array assignments if the right-hand side is a function call that has
21076 been inlined. Check is performed on the assignment in the block.
21077 (Process_Bounds): If bounds and range are overloaded, apply preference
21078 rule for root operations to disambiguate, and diagnose true ambiguity.
21079 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21080 a tag-indeterminate right-hand side even when Expander_Active is True.
21081 Needed to ensure that dispatching calls to T'Input are allowed and
21082 get the tag of the target class-wide object.
21083
21084 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21085 an inherited primitive operation that already overrides several
21086 abstract interface primitives. For transitivity, the new entity must
21087 also override all the abstract interface primitives covered by the
21088 inherited overriden primitive.
21089 Emit warning if new entity differs from homograph in same scope only in
21090 that one has an access parameter and the other one has a parameter of
21091 a general access type with the same designated type, at the same
21092 position in the signature.
21093 (Make_Inequality_Operator): Use source locations of parameters and
21094 subtype marks from corresponding equality operator when creating the
21095 tree structure for the implicit declaration of "/=". This does not
21096 change anything in behaviour except that the decoration of the
21097 components of the subtree created for "/=" allows ASIS to get the
21098 string images of the corresponding identifiers.
21099 (Analyze_Return_Statement): Remove '!' in warning message.
21100 (Check_Statement_Sequence): Likewise.
21101 (Analyze_Subprogram_Body): For an access parameter whose designated type
21102 is an incomplete type imported through a limited_with clause, use the
21103 type of the corresponding formal in the body.
21104 (Check_Returns): Implicit return in No_Return procedure now raises
21105 Program_Error with a compile time warning, instead of beging illegal.
21106 (Has_Single_Return): Function returning unconstrained type cannot be
21107 inlined if expression in unique return statement is not an identifier.
21108 (Build_Body_To_Inline): It is possible to inline a function call that
21109 returns an unconstrained type if all return statements in the function
21110 return the same local variable. Subsidiary procedure Has_Single_Return
21111 verifies that the body conforms to this restriction.
21112
21113 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21114 same type, and one of them is of an anonymous access type, convert
21115 the other operand to it, so that this is a valid binary operation for
21116 gigi.
21117 (Resolve_Type_Conversion): Handle subtypes of protected types and
21118 task types when accessing to the corresponding record type.
21119 (Resolve_Allocator): Add '\' in 2-line warning message.
21120 Remove '!' in warning message.
21121 (Resolve_Call): Add '\' in 2-line warning message.
21122 (Valid_Conversion): Likewise.
21123 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21124 resulting type may be an access type with an implicit dereference.
21125 Obtain the proper component from the designated type.
21126 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21127 given by an expanded name with prefix Standard, when the operands are
21128 of an anonymous access type.
21129 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21130 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21131 prefix of the expression is not of an incomplete type. Allows full
21132 diagnoses of all semantic errors.
21133 (Resolve_Actuals): If the actual is an allocator whose directly
21134 designated type is a class-wide interface we build an anonymous
21135 access type to use it as the type of the allocator. Later, when
21136 the subprogram call is expanded, if the interface has a secondary
21137 dispatch table the expander will add a type conversion to force
21138 the displacement of the pointer.
21139 (Resolve_Call): If a function that returns an unconstrained type is
21140 marked Inlined_Always and inlined, the call will be inlined and does
21141 not require the creation of a transient scope.
21142 (Check_Direct_Boolean_Op): Removed
21143 (Resolve_Comparison_Op): Remove call to above
21144 (Resolve_Equality_Op): Remove call to above
21145 (Resolve_Logical_Op): Inline above, since this is only call.
21146 (Valid_Conversion): Handle properly conversions between arrays of
21147 convertible anonymous access types.

21159 definitions that are access definitions.

21161 procedure is not considered a dispatching call and will be expanded
21162 properly.

21167 controlling argument of the dispatching call is an abstract interface
21168 class-wide type then we use it directly.
21169 Check No_Dispatching_Calls restriction.
21170 (Default_Prim_Op_Position): Remove the code that looks for the last
21171 entity in the list of aliased subprograms. This code was wrong in
21172 case of renamings.
21173 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21174 when the source is compiled with the No_Dispatching_Calls restriction.
21175 (Init_Predefined_Interface_Primitives): No need to inherit primitives
21176 if we are compiling with restriction No_Dispatching_Calls.
21177 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21178 subprograms if we are compiling under No_Dispatching_Calls restriction.
21179 (Make_DT): Generate a dispatch table with a single dummy entry if
21180 we are compiling with the No_Dispatching_Calls restriction. In
21181 addition, in this case we don't generate code that calls to the
21182 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21183 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21184 of this subprogram if compiling with the No_Dispatching_Calls
21185 restriction.
21186 (Expand_Type_Conversion): Instead of using the actual parameter,
21187 the argument passed as parameter to the conversion function was
21188 erroneously referenced by the expander.
21189 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21190 Set_Predefined_Primitive_Op_Address and Set_Signature.
21191 (Expand_Dispatching_Call): Generate call to
21192 Get_Predefined_Prim_Op_Address for predefined primitives.
21193 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21194 predefined primitives.
21195 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21196 primitives we reserve one dummy entry to ensure that the tag does not
21197 point to some memory that is associated with some other object. In
21198 addition, remove all the old code that generated the assignments
21199 associated with the signature of the dispatch table and replace them
21200 by a call to the new subprogram Set_Signature.
21201 (Set_All_DT_Position): Change the algorithm because now we have a
21202 separate dispatch table associated with predefined primitive operations.
21203 (Expand_Interface_Conversion): In case of non-static offset_to_top
21204 add explicit dereference to get access to the object after the call
21205 to displace the pointer to the object.
21206 (Expand_Interface_Thunk): Modify the generation of the actual used
21207 in the calls to the run-time function Offset_To_Top to fulfil its
21208 new interface.
21209 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.

21493 Analyze_Compilation_Unit.
21494 Detect and warn on redundant with clauses detected in a package spec
21495 and/or body when -gnatwr is used.
21496 (Analyze_Context): Analyze config pragmas before other items
21497 (Install_Context_Items): Don't analyze config pragmas here
21498 (Install_Limited_Withed_Unit): Set limited entity of package in
21499 with_clause so that cross-reference information or warning messages on
21500 unused packages can be properly generated
21501 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21502 has Error_Posted set. Prevent infinite loops in illegal programs.
21503 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21504 to the point of the error test requiring the current unit to be private.
21505 This ensures that private with clauses are not exempted from the basic
21506 checking for being a descendant of the same library unit parent as a
21507 withed private descendant unit.
21508 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21509 handle private with clauses properly, as well as to account for cases
21510 where the withed unit is a public descendant of a private ancestor
21511 (in which case the current unit must be a descendant of the private
21512 ancestor's parent). The spec comments were updated accordingly. Also,
21513 the old error message in this subprogram was replaced with error
21514 messages that mirror the errors tested and reported by
21515 Check_Private_Child_Unit.
21516 Parameter and variable names improved for readability.
21517 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21518 private as the precondition for calling
21519 Check_Private_Limited_Withed_Unit since that subprogram has been
21520 revised to test public units as well as private units.

21531 (Formal_Entity): Complete rewrite, to handle properly some complex case
21532 with multiple levels of parametrization by formal packages.

21539 controlled types.
21540 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21541 conform to AI-216.
21542 Add pragma Ada_2005 (synonym for Ada_05)
21543 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21544 were not always properly handled previously.

21547 (Set_Convention_From_Pragma): Check that if a convention is
21548 specified for a dispatching operation, then it must be
21549 consistent with the existing convention for the operation.
21550 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21551 longer required to specify an vtable-ptr component in the record. For
21552 compatibility reasons we leave the support for the previous definition.
21553 (Analyze_Pragma, case No_Return): Allow multiple arguments
21554
21555 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21556 non-overrideen inherited operation with a controlling result as
21557 illegal only its implicit declaration comes from the derived type
21558 declaration of its result's type.
21559 (Check_Possible_Deferred_Completion): Relocate the object definition
21560 node of the subtype indication of a deferred constant completion rather
21561 than directly analyzing it. The analysis of the generated subtype will
21562 correctly decorate the GNAT tree.
21563 (Record_Type_Declaration): Check whether this is a declaration for a
21564 limited derived record before analyzing components.
21565 (Analyze_Component_Declaration): Diagnose record types not explicitly
21566 declared limited when a component has a limited type.
21567 (Build_Derived_Record_Type): Code reorganization to check if some of
21568 the inherited subprograms of a tagged type cover interface primitives.
21569 This check was missing in case of a full-type associated with a private
21570 type declaration.
21571 (Constant_Redeclaration): Check that the subtypes of the partial and the
21572 full view of a constrained deferred constant statically match.
21573 (Mentions_T): A reference to the current type in an anonymous access
21574 component declaration must be an entity name.
21575 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21576 class_wide type to refer to full type, not to the incomplete one.
21577 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21578 available. Required to give support to the certified run-time.
21579 (Analyze_Component_Declaration): In case of anonymous access components
21580 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21581 (Process_Discriminants): For an access discriminant, use the
21582 discriminant specification as the associated_node_for_itype, to
21583 simplify accessibility checks.

21587
21588 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21589 abstract interpretations on an operator, remove interpretations that
21590 yield Address or a type derived from it, if one of the operands is an
21591 integer literal.
21592 (Try_Object_Operation.Try_Primitive_Operation,
21593 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21594 location when creating the new reference to a primitive or class-wide
21595 operation as a part of rewriting a subprogram call.
21596 (Try_Primitive_Operations): If context requires a function, collect all
21597 interpretations after the first match, because there may be primitive
21598 operations of the same type with the same profile and different return
21599 types. From code reading.
21600 (Try_Primitive_Operation): Use the node kind to choose the proper
21601 operation when a function and a procedure have the same parameter
21602 profile.
21603 (Complete_Object_Operation): If formal is an access parameter and prefix
21604 is an object, rewrite as an Access reference, to match signature of
21605 primitive operation.
21606 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21607 by an expanded name with prefix Standard, when the operands are of an
21608 anonymous access type.
21609 (Remove_Abstract_Operations): If the operation is abstract because it is
21610 inherited by a user-defined type derived from Address, remove it as
21611 well from the set of candidate interpretations of an overloaded node.
21612 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21613 types.
21614
216152006-02-13 Bob Duff <duff@adacore.com>
21616
21617 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21618 redundant use clauses.
21619 In particular, if the scope of two use clauses overlaps, but one is not
21620 entirely included in the other, we should not warn. This can happen
21621 with nested packages.
21622 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21623 reported errors. The bug was reported when the compiler was built
21624 with assertions enabled.
21625 (Find_Type): If the node is a 'Class reference and the prefix is a
21626 synchronized type without a corresponding record, return the type
21627 itself.
21628
216292006-02-13 Javier Miranda <miranda@adacore.com>

21632 if this is the full-declaration associated with a private declaration
21633 that implement interfaces, then the private type declaration must be
21634 limited.
21635 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21636 as aliased. The use of the 'access attribute is not available for such
21637 object (for this purpose the object should be explicitly marked as
21638 aliased, but being an anonymous type this is not possible).

21652 interpretations.
21653 (Add_One_Interp): Do not add to the list of interpretations aliased
21654 entities corresponding with an abstract interface type that is an
21655 immediate ancestor of a tagged type; otherwise we have a dummy
21656 conflict between this entity and the aliased entity.
21657 (Disambiguate): The predefined equality on universal_access is not
21658 usable if there is a user-defined equality with the proper signature,
21659 declared in the same declarative part as the designated type.
21660 (Find_Unique_Type): The universal_access equality operator defined under
21661 AI-230 does not cover pool specific access types.
21662 (Covers): If one of the types is a generic actual subtype, check whether
21663 it matches the partial view of the other type.

21702
21703 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,

21706 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21707 This prevents scanning leading blanks and sign twice.

aedc2c2b
AC		 21917
21918 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21919 link to the version that does nothing. This way the task termination
21920 routine is not executed twice for the environment task when finishing
21921 because of an unhandled exception.
21922
21923 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21924 handler because of an unhandled exception.
21925
21926 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21927 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21928
21929 * s-finimp.adb (initialization code): Modify the soft link for the
21930 finalization of the global list instead of Adafinal.
21931
21932 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21933 non-tasking version of the soft link for task termination. We do
21934 nothing since if we are using the non-tasking version it
21935 means that the task termination functionality is not used.
21936 (Null_Finalize_Global_List): Add this null version for the procedure
21937 in charge of finalizing the global list for controlled objects.
21938 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21939 instead for handling run-time termination in a more flexible way.
21940 (Adafinal_NT): This new procedure will take care of finalizing the
21941 global list for controlled objects if needed, but no tasking
21942 finalization.
21943
21944 * s-tarest.adb (Task_Lock): Do not try to lock again the
21945 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21946 some run-time operations.
21947 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21948 until all nested locks have been released.
21949 (Task_Wrapper): Call the fall-back task termination handler. It
21950 applies to all tasks but the environment task.
21951 (Finalize_Global_Tasks): Add the call for the task termination
21952 procedure for the environment task.
21953 (Task_Wrapper): suppress warnings around declaration of
21954 Secondary_Stack_Address.

21959 Common_ATCB record.
21960 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21961 Common_ATCB record.
21962
21963 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21964 Fall_Back_Handler, and Specific_Handler.
21965
21966 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21967 defined in Ada.Task_Termination, to avoid circular dependencies.
21968 (Termination_Handler): Redefine this type here, alredy defined in
21969 Ada.Task_Termination, for avoiding circular dependencies.
21970 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21971 for storing task termination handlers. In addition,
21972 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21973 Common_ATCB because it is used by both the regular and the restricted
21974 run times.
21975 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21976 Common_ATCB because it is used by both the regular and the restricted
21977 run times.
21978 (Common_ATCB): Added a dynamic task analyzer field.
21979
21980 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21981 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21982 (Task_Wrapper): Call the task termination handler. It applies to all
21983 tasks but the environment task.
21984 (Finalize_Global_Tasks): Call the task termination procedure for the
21985 environment task. The call to Finalize_Global_List is now performed
21986 using the soft links mechanism.
21987 (Task_Wrapper): added dynamic stack analysis.
21988
21989 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21990 potentially blocking operations has been moved from
21991 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21992 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21993 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21994 this run-time check.
21995
21996 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21997 of task termination procedure.
21998 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21999 link for the task termination procedure.

22039
22040 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
22041 to the specification because the frontend generates code that uses this
22042 subprogram.
22043 (Set_Interface_Table): Add missing assertion.
22044 Update documentation describing the run-time structure.
22045 (Displace): New subprogram that displaces the pointer to the object
22046 to reference one of its secondary dispatch tables.
22047 (IW_Membership): Modified to use the new table of interfaces.
22048 (Inherit_TSD): Modified to use the new table of interfaces.
22049 (Register_Interface_Tag): Use the additional formal to fill the
22050 contents of the new table of interfaces.
22051 (Set_Interface_Table): New subprogram that stores in the TSD the
22052 pointer to the table of interfaces.
22053 (Set_Offset_To_Top): Use the additional formal to save copy of

22065
22066 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
22067 in all the calls to Expand_Interface_Thunk. Instead of referencing the
22068 record component containing the tag of the secondary dispatch table we
22069 have to use the Offset_To_Top run-time function to get this information;
22070 otherwise if the pointer to the base of the object has been displace
22071 we get a wrong value if we use the 'position attribute.
22072
22073 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
22074 all the calls to Expand_Interface_Thunk.
22075 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

22078 ensure that the interfaces implemented by the ancestors are placed
22079 at the header of the generated list.

22084 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
22085 Get_Tagged_Kind and Set_Tagged_Kind.
22086 (Tagged_Kind): New function that determines the tagged kind of a type
22087 with respect to limitedness and concurrency and returns a reference to
22088 RE_Tagged_Kind.
22089 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,

22109 RE_TK_Tagged, RE_TK_Task.
22110
22111 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22112 Init_Secondary_Tags_Internal to allow its use with interface types and
22113 also to generate the code for the new additional actual required
22114 by Set_Offset_To_Top.
22115 (Build_Init_Statements): In case of components associated with abstract
22116 interface types there is no need to generate a call to its IP.
22117 (Freeze_Record_Type): Generate Select Specific Data tables only for
22118 concurrent types.

22315 legal within a protected type that implements an interface.
22316 (Collect_Interfaces): Do not add to the list the interfaces that

22318 (Derived_Type_Declaration): If the parent of the full-view is an
22319 interface perform a transformation of the tree to ensure that it has
22320 the same parent than the partial-view. This simplifies the job of the
22321 expander in order to generate the correct object layout, and it is
22322 needed because the list of interfaces of the full-view can be given in
22323 any order.
22324 (Process_Full_View): The parent of the full-view does not need to be
22325 a descendant of the parent of the partial view if both parents are
22326 interfaces.
22327 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22328 "limited" the parent must be a limited type.

22401 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
22402 available user-specified stream attributes on limited parameters to
22403 also test the type directly rather than only its underlying type (for
22404 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22405 attributes are visible at the point of the subprogram declaration.
22406 For Ada 2005, the error message is modified to indicate that the
22407 type's stream attributes must be visible (again, only for -gnat05).

22439 types use the corresponding record type. This was not needed before
22440 the implementation of Ada 2005 synchronized types because

22704 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22705 a string literal for precise control over warnings.

22709 * sem_prag.ads: Minor reformatting
22710
22711 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"

22715 Allow optional = after -gnatm
22716 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22717 longer sets Elaboration_Checks.
22718 Code to set warning mode moved to Sem_Warn
22719 so that it can be shared by pragma processing.
22720
22721 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22829 deferral level, when abort is not allowed, to a later stage (the
22830 Task_Wrapper).
22831 (Task_Wrapper): If Abort is not allowed, reset the deferral level since
22832 it will not get changed by the generated code. It was previously done
22833 in Create_Task.
22834

22843 (annotate_rep): Don't restrict the back annotation of inherited
22844 components to the type_annotate_only case.
22845 (gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
22846 we are not defining the type.
22847 <E_Record_Type>: Likewise.
22848 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22849 to get advantage of the new maybe_stabilize_reference interface, to
22850 ensure that what we reference is indeed stabilized instead of relying
22851 on assumptions on what the stabilizer does.
22852 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22853 type imported through a limited_with clause, use its non-limited view.
22854 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22855 differentiation.
22856 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22857 of #if sections + explicit comparisons of convention identifiers.
22858 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
22859 before early-returning for certain types when code generation is
22860 disabled.
22861 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22862 nullification of gnu_expr we do for objects with address clause and
22863 that we are not defining.
22864 (elaborate_expression_1): Do not create constants when creating
22865 variables needed by the debug info: the dwarf2 writer considers that
22866 CONST_DECLs is used only to represent enumeration constants, and emits
22867 nothing for them.
22868 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22869 object with an address clause into an indirect reference, drop the
22870 initializing expression.
22871 Include "expr.h".
22872 (STACK_CHECK_BUILTIN): Delete.

22877 corresponding to the renamed object as ignored for debugging purposes.
22878
22879 * trans.c (tree_transform, case N_Attribute_Reference, case Attr_Size &
22880 related): For a prefix that is a dereference of a fat or thin pointer,
22881 if there is an actual subtype provided by the front-end, use that
22882 subtype to build an actual type with bounds template.
22883 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22884 is provided by the front-end, use that subtype to compute the size of
22885 the deallocated object.
22886 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22887 check for a potential violation of a No_Elaboration_Code restriction.
22888 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22889 with extra arguments to control whether to recurse through non-values
22890 and to let the caller know if the stabilization has succeeded.
22891 (gnat_stabilize_reference): Now a simple wrapper around
22892 maybe_stabilize, for common uses without restriction on lvalues and
22893 without need to check for the success indication.
22894 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22895 pass false instead of 0 as the FORCE argument which is a bool.
22896 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22897 attached to a renaming pointer has been properly stabilized, as no such
22898 object is attached otherwise.
22899 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22900 function uses the "target pointer" return mechanism.
22901 Reinstate conversion of the actual to the type of the formal
22902 parameter before any other specific treatment based on the passing
22903 mechanism. This turns out to be necessary in order for PLACEHOLDER
22904 substitution to work properly when the latter type is unconstrained.
22905
22906 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
22907 common pattern.
22908 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22909 with extra arguments to control whether to recurse through non-values
22910 and to let the caller know if the stabilization has succeeded.
22911
22912 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22913 static output of record constructor if all the components are constant.
22914 (gnat_build_constructor): For a record type, sort the list of field
22915 initializers in increasing bit position order.
22916 Factor common code to build a storage type for an unconstrained object
22917 from a fat or thin pointer type and a constrained object type.
22918 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22919 types variants, and process special cases of VIEW_CONVERT expressions
22920 as their NOP_EXPR counterpart to ensure we get to the
22921 CORRESPONDING_VARs associated with CONST_DECls.
22922 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22923 on the right-hand side.
22924
22925 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
22926 a common pattern.
22927 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
22928 are converting back to its original type.
22929 (convert) <JM input>: Fallthrough regular conversion code instead of
22930 extracting the object if converting to a type variant.
22931 (create_var_decl): When a variable has an initializer requiring code
22932 generation and we are at the top level, check for a potential violation
22933 of a No_Elaboration_Code restriction.
22934 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22935 SIZE and SIZE_UNIT which we need for later back-annotations.
22936 * utils.c: (convert) <STRING_CST>: Remove obsolete code.
22937 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
22938 is an unchecked union.
22939 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22940 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22941 main variant, just replace the VIEW_CONVERT_EXPR.

22943
22944 * repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.
22945
22946 * repinfo.adb (Print_Expr, Rep_Value): Handle Bit_And_Expressions.

23082 (Gen_Assign): If the component being assigned is an array type and the

23117 and related): For a prefix that is an explicit dereference of an
23118 access to unconstrained packed array type, annotate the dereference
23119 with an actual subtype so GIGI can make a correct size computation.
23120 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
23121 'Unrestricted_Access, if the designated type is an interface we
23122 add a type conversion to force the displacement of the pointer
23123 to the secondary dispatch table.
23124 Use Universal_Real instead of Long_Long_Float when we need a high
23125 precision float type for the generated code (prevents gratuitous

23150 assignment of a value of a tagged type that has been rewritten to a
23151 block statement, it is known by construction that no checks are
23152 necessary for the statements within the block: analyze it with checks
23153 suppressed.
23154 (Expand_N_If_Statement): When killing a dead then-branch in an
23155 if-statement that has elsif_parts, recompute the Current_Value node

23157 elsif_part.
23158 (Expand_N_Return_Statement): When returning a mutable record, convert
23159 the return value into its actual subtype in order to help the backend
23160 to return the actual size instead of the maximum. This is another
23161 aftermath of not returning mutable records on the sec-stack anymore.

23534 package instance of a generic child package.
23535 (Analyze_Package_Specification): When entering a private part of a
23536 package associated with a generic instance or formal package, the
23537 private declarations of the parent must be installed (by calling new
23538 procedure Install_Parent_Private_Declarations).
23539 Change name Is_Package to Is_Package_Or_Generic_Package

23548 on the type may not have been generated.
23549 Handle properly a renaming_as_body generated for a stream operation
23550 whose default is abstract because the object type itself is abstract.
23551 (Find_Type): If the type is incomplete and appears as the prefix of a
23552 'Class reference, it is tagged, and its list of primitive operations
23553 must be initialized properly.
23554 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23555 private declaration of a parent unit, prior to compiling the private
23556 part of a child unit, find on the scope stack the proper parent entity
23557 on which to link the use clause.
23558 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23559 detected.

23581 remove address operations.
23582 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
23583 statement to inhibit warning.
23584 (Resolve_Unary_Op): Do not produce a warning when
23585 processing an expression of the form -(A mod B)
23586 Use Universal_Real instead of Long_Long_Float when we need a high
23587 precision float type for the generated code (prevents gratuitous
23588 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23589 (Resolve_Concatenation_Arg): Improve error message when argument is an
23590 ambiguous call to a function that returns an array.
23591 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
23592 there is an implicit operator in the given scope if we are within an
23593 instance: legality check has been performed on the generic.
23594 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
23595 after resolving operand, to avoid false warnings on overloaded calls.

24183 check on the level of the return expression of a class-wide function
24184 can be elided. The check usually isn't needed if the expression has a
24185 specific type (unless it's a conversion or a formal parameter). Also
24186 add a test for whether accessibility checks are suppressed. Augment
24187 the comments to describe the conditions for performing the check.

24322 expanded in the code that returns the value of the displaced actual.
24323 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
24324 conversions that have no effect in the generated code because no
24325 displacement is required. Code cleanup; use local variables to

98b40956
AC		 24422 Move all target-specific file inclusions and macro definitions to

24628 position set is provided, we compute one in order to reduce the maximum
24629 length of the keys. This computation first selects a character
24630 position between 1 and the minimum length of the keys in order to
24631 avoid reducing one of the keys to an empty string.
24632 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24633 does not converge. The initialization procedure now comes with a
24634 maximum number of iterations such that when exceeded, an exception is
24635 raised in Compute. The user can initialize this ratio to another value
24636 and try again

24642 that given an entity T creates and returns an Itype that duplicates the
24643 contents of T. The returned Itype has the null-exclusion
24644 attribute set to True, and its Etype attribute references T

24772 location of the prefix (not the location of the attribute reference) as
24773 the error location.
24774 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24775 a function renaming thereof, is a valid prefix for 'Size (where it is
24776 intepreted as a function call).
24777 (Statically_Denotes_Entity): New predicate to determine whether the

24794 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24795 become local to the whole package.
24796 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24797 the package was already analyzed the new algorithm "replaces" the
24798 real entities by the shadow ones. This is required to ensure that
24799 the order of these entities in the homonym chains does not change;
24800 otherwise we can have undefined references at linking time because
24801 in case of conflicts the external name of the entities will have
24802 a suffix that depends on the order of the entities in the chain.
24803 (Remove_Limited_With_Clause): Complementary code that completes the
24804 new algorithm and replaces the shadow entities by the real ones.
24805 (Install_Limited_Withed_Unit): When unchaining entities before the
24806 installation of the shadow entities, only regular entities of the
24807 public part must be taken into account. This is required to
24808 keep this routine in synch with the work done by Remove_Limited_
24809 With_Clause
24810 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24811 even if unit is analyzed, because the analysis of the unit is
24812 idempotent in any case, and the limited view of the unit may have to
24813 be installed for proper visibility.
24814 (Expand_Limited_With_Clause): Even if the unit in the implicit
24815 with_clause has been analyzed already, a limited view of the package
24816 must be built for the current context, if it does not exist yet.

24824 rather than copying the entity of the spec, to prevent accidental
24825 sharing of the entity list.
24826 (Check_Private_View): When exchanging views of private types, build the
24827 list of exchanged views as a stack, to ensure that on exit the exchanges
24828 are undone in the proper order.
24829 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24830 Restore the compilation environment in case of instantiation_error.
24831 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24832 for an anonymous access result.

24847 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24848 underlying type
24849 to check if a type is Constrained in cases related to code generation
24850 (rather than semantic checking) since otherwise we do not generate
24851 similar code for mutable private types depending if their
24852 discriminants are visible or not.
24853 (Check_Abstract_Overriding): Do not complain about failure to override
24854 the primitive operations used in dispatching selects since they will
24855 always be overriden at the freeze point of the type.
24856 (Access_Definition): Separate out handling for resetting the scope
24857 of an anonymous access function result type. Retrieve the scope
24858 of the associated function rather than using Current_Scope, which
24859 does not have a consistent value (depends on whether we're in the
24860 middle of analyzing formal parameters). Add ??? comment about
24861 finding a cleaner way to handle the special cases of scope setting.
24862 (Process_Incomplete_Dependents): A protected operation is never a
24863 dispatching operation (only its wrapper may be).
24864 (Build_Derived_Record_Type): In case of tagged private types that
24865 implement interfaces add derivation of predefined primitive
24866 operations.
24867 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24868 by two parameters that are used in case of derivation from abstract
24869 interface types: No_Predefined_Prims is used to avoid the derivation
24870 of predefined primitives from the interface, and Predefined
24871 Prims_Only is used to complete the derivation predefined primitives
24872 in case of private tagged types implementing interfaces.
24873 Fix typo in comments
24874 (Find_Interface_In_Descendant): Protect the frontend against
24875 wrong code with large circularity chains.
24876 (Is_Private_Overriding): Add support for entities overriding interface
24877 subprograms. The test failed because Entities associated with overriden
24878 interface subprograms are always marked as hidden (and used to build
24879 the secondary dispatch table); in this case the overriden entity is
24880 available through the field abstract_interface_alias (cf. override_
24881 dispatching_operation)
24882 (Access_Definition): Set the scope of the type to Current_Scope for the
24883 case of a function with an anonymous access result type.
24884 (Access_Subprogram_Declaration): Handle creation of the type entity for
24885 an access-to-function type with an anonymous access result.
24886 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24887 in handling for N_Access_Function_Definition.

24899 (Process_Subtype): Create the new null-excluding itype if
24900 required. Code cleanup.
24901 (Build_Derived_Record_Type): Code cleanup to avoid calling
24902 twice the subprogram derive_subprograms in case of private
24903 types that implement interfaces. In this particular case the
24904 subprogram Complete_Subprograms_Derivation already does the
24905 job associated with the second call.

24915 V (Obj.F), the rewriting does not involve the indexed component, but
24916 only the selected component itself.
24917 Do not apply the transformation if the analyzed node is an actual of a
24918 call to another subprogram.
24919 (Complete_Object_Operation): Retain the entity of the
24920 dispatching operation in the selector of the rewritten node. The
24921 entity will be used in the expansion of dispatching selects.
24922 (Analyze_One_Call): Improve location of the error message associated
24923 with interface.
24924 (Analyze_Selected_Component): No need to resolve prefix when it is a
24925 function call, resolution is done when parent node is resolved, as
24926 usual.
24927 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24928 when attempting to resolve a call transformed from its object notation.
24929 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24930 of the argument list for each interpretation of the operation.
24931 (Try_Object_Operation): The designated type of an access parameter may
24932 be an incomplete type obtained through a limited_with clause, in which
24933 case the primitive operations of the type are retrieved from its full
24934 view.
24935 (Analyze_Call): If this is an indirect call, and the return type of the
24936 access_to_subprogram is incomplete, use its full view if available.

24941 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24942 access types the null-exclusion and access-to-constant attributes must
24943 also match.
24944 (Analyze_Return_Statement): When the result type is an anonymous access
24945 type, apply a conversion of the return expression to the access type
24946 to ensure that appropriate accessibility checks are performed.
24947 (Analyze_Return_Type): For the case of an anonymous access result type,
24948 generate the Itype and set Is_Local_Anonymous_Access on the type.
24949 Add ??? placeholder for check to disallow returning a limited object
24950 in Ada 2005 unless it's an aggregate or a result of a function call.
24951 Change calls from Subtype_Mark to Result_Definition.

24957 Result_Definition in call to Make_Function_Specification.
24958 (Process_Formals): Create the new null-excluding itype if required.
24959 (New_Overloaded_Entity): For an entity overriding an interface primitive
24960 check if the entity also covers other abstract subprograms in the same
24961 scope. This is required to handle the general case, that is, overriding
24962 other interface primitives and overriding abstract subprograms inherited
24963 from some abstract ancestor type.
24964 (New_Overloaded_Entity): For an overriding entity that comes from
24965 source, note the operation that it overrides.
24966 (Check_Conformance, Type_Conformant): Addition of one new formal
24967 to skip controlling formals in the analysis. This is used to
24968 handle overloading of abstract interfaces.
24969 (Base_Types_Match): Add missing case for types imported from
24970 limited-with clauses

24977 verify that the procedure and the entry are mode conformant.
24978 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24979 as a different operator, which is often a cut-and-paste error.

24984 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24985 used in controlling parameters exclude null because it is necessary to
24986 read the tag to dispatch, and null has no tag.
24987 (Override_Dispatching_Operation): If the previous operation is inherited
24988 from an interface, it becomes hidden and does not participate in later
24989 name resolution.

24994
24995 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24996 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24997 the expander will generate the corresponding run-time check to evaluate
24998 the expression.
24999 (Resolve_Call): Check for legal type of procedure name or prefix that
25000 appears as a trigger in a triggering alternative.
25001 (Valid_Conversion): If expression is ambiguous and the context involves
25002 an extension of System, remove System.Address interpretations.
25003 (Resolve_Qualified_Expression): Reject the case of a specific-type
25004 qualification applied to a class-wide argument. Enhance comment
25005 to explain checking of Original_Node.
25006 (Resolve_Type_Conversion): The location of the error message was not
25007 general enough to handle the general case and hence it has been removed.
25008 In addition, this patch improves the text of the message.
25009 (Resolve_Type_Conversion): Add missing support for access to interface
25010 types.
25011 (Resolve_Type_Conversion): If the target is a class-wide interface type,
25012 do not expand if the expression is the actual in a call, because proper
25013 expansion will take place when the call itself is expanded.
25014 (Resolve_Allocator): If the context is an unchecked conversion, the
25015 allocator inherits its storage pool, if any, from the target type of
25016 the conversion.

25021 * sem_type.adb (Add_One_Interp): If a candidate operation is an
25022 inherited interface operation that has an implementation, use the
25023 implementation to avoid spurious ambiguities.
25024 (Interface_Present_In_Ancestor): In case of concurrent types we can't
25025 use the Corresponding_Record_Typ attribute to look for the interface
25026 because it is set by the expander (and hence it is not always
25027 available). For this reason we traverse the list of interfaces
25028 (available in the parent of the concurrent type).

25036 primitive procedure of a limited interface with a controlling first
25037 parameter.
25038 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
25039 of an entry.
25040 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25041 capture if it is generated in the second operand of a short-circuit
25042 operation.
25043 Do not capture values for variables with address clauses.

25045 if its type is not Standard_Void_Type.

25832 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25833 longer protected objects. They have been replaced by lower-level
25834 suspension objects made up by a mutex and a condition variable (or
25835 their equivalent given a particular OS) plus some internal data to
25836 reflect the state of the suspension object.
25837 (Initialize, Finalize): Add this initialization procedure for
25838 Suspension_Object, which is a controlled type.
25839 (Finalize): Add the finalization procedure for Suspension_Object,
25840 which is a controlled type.
25841
25842 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25843 Ada.Synchronous_Task_Control because there is no longer a need for a
25844 VxWorks specific version of this package. Target dependencies
25845 has been moved to System.Task_Primitives.Operations.
25846

25848 longer needed.
25849 (InitializeCriticalSection, EnterCriticalSection,

25859 set the environment task mask here.
25860 (Current_State): Add this function that returns the state of the
25861 suspension object.
25862 (Set_False): Add this procedure that sets the state of the suspension
25863 object to False.
25864 (Set_True): Add this procedure that sets the state of the suspension
25865 object to True, releasing the task that was suspended, if any.
25866 (Suspend_Until_True): Add this procedure that blocks the calling task
25867 until the state of the object is True. Program_Error is raised if
25868 another task is already waiting on that suspension object.
25869 (Initialize): Add this procedure for initializing the suspension
25870 object. It initializes the mutex and the condition variable which are
25871 used for synchronization and queuing, and it sets the internal state
25872 to False.
25873 (Finalize): Add this procedure for finalizing the suspension object,
25874 destroying the mutex and the condition variable.

25880 which provides a low-level abstraction (using operating system
25881 primitives) for Ada.Synchronous_Task_Control.
25882 This object is made up by a mutex (for ensuring mutual exclusion), a
25883 condition variable (for queuing threads until the condition is
25884 signaled), a Boolean (State) indicating whether the object is open,
25885 and a Boolean (Waiting) reflecting whether there is a task already

25994
25995 * mlib-tgt-mingw.adb (Build_Dynamic_Library): Replace the previous
25996 implementation. This new version generates the proper DllMain routine

26091 (Make_Abstract_Interface_DT): Minor code cleanup.
26092 (Set_All_DT_Position): Code cleanup. As part of the code cleanup
26093 this subprogram implements a new algorithm that provides the
26094 same functionality and it is more clear in case of primitives
26095 associated with abstract interfaces.
26096 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
26097 clean up, the functionality of this subprogram is now provided
26098 by Set_All_DT_Position.

26111 the object to give access to the interface tag associated with the
26112 secondary dispatch table.

26142 access component.
26143 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
26144 an access component in this context is a Local_Anonymous_Access, for
26145 proper accessibility checks.
26146 (Access_Definition): Set properly the scope of the anonymous access type

26162 derivation if the derived type has an ancestor that is a formal type
26163 declared in the formal part of an enclosing generic.
26164 (Analyze_Object_Declaration): For protected objects, remove the check
26165 that they cannot contain interrupt handlers if not declared at library
26166 level.
26167 (Add_Interface_Tag_Components): New subprogram to add the tag components
26168 corresponding to all the abstract interface types implemented by a
26169 record type or a derived record type.

26184 Derived_Type_Declaration, Find_Type_Name, Inherit_Components,
26185 Process_Full_View, Record_Type_Declaration): Modified to give
26186 support to abstract interface types

26188 we are in the case of an abstact-interface derivation
26189 (Find_Type_Of_Subtype_Indic): Moved from the body of the package
26190 to the specification because it is requied to analyze all the

26194
26195 * exp_ch3.adb: Implement config version of persistent_bss pragma

26199 Make_Abstract_Interfaces_DT to generate the secondary tables
26200 associated with abstract interfaces.
26201 (Build_Init_Procedure): Modified to initialize all the tags
26202 corresponding.
26203 (Component_Needs_Simple_Initialization): Similar to other tags,

26210 * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an
26211 in-out parameter that is a component in an initialization procedure,
26212 whose constraint might depend on discriminants, and that may be
26213 misaligned because of packing or representation clauses.
26214 (Is_Legal_Copy): New predicate to determine whether a possibly
26215 misaligned in-out actual can actually be passed by copy/return. This
26216 is an error in case the type is by_reference, and a warning if this is
26217 the consequence of a DEC import pragma on the subprogram.
26218 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
26219 interface types
26220 (Expand_Inlined_Call): Mark temporary generated for the return value as
26221 internal, so that no useless scalar normalization is generated for it.
26222 (Expand_N_Subprogram_Declaration): Save unanalyzed body so calls to
26223 null procedure can always be inlined.
26224 (Expand_N_Subprogram_Declaration): If this is the declaration of a null
26225 procedure, generate an explicit empty body for it.
26226
26227 * exp_util.ads, exp_util.adb (Find_Interface_ADT): New subprogram.
26228 Given a type implementing an interface, returns the corresponding
26229 access_disp_table value.

26237 is a predefined primitive operation.
26238 (Expand_Subtype_From_Expr): If the expression is a selected component

0adcdb66
AC		 26243 This package has been left available for compatibility with previous
26244 versions of the frontend. As part of the new layout this is now a
26245 dummy package that uses declarations available at a-tags.ads
26246
26247 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of
26248 "constant access" and "aliased [constant] access" when not compiling
26249 with -gnat05.

26259 for a subprogram or instance declaration.
26260
26261 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Verify that an
26262 instantiation that is a dispatching operation has controlling access
26263 parameters that are null excluding.

26265 (Validate_Derived_Type_Instance): Add check for abstract interface
26266 types.
26267 (Analyze_Formal_Package): Establish Instantiation source for the copy of
26268 the generic that is created to represent the formal package.
26269 (Analyze_Package_Instantiation): Instantiate body immediately if the
26270 package is a predefined unit that contains inlined subprograms, and
26271 we are compiling for a Configurable_Run_Time.

26276 error message condition, null procedures are correctly detected now.
26277 (New_Overloaded_Entity): Bypass trivial overriding indicator check
26278 for subprograms in the context of protected types. Instead, the
26279 indicator is examined in Sem_Ch9 while analysing the subprogram
26280 declaration.
26281 (Check_Overriding_Indicator): Check consistency of overriding indicator
26282 on subprogram stubs as well.
26283 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
26284 the library level.
26285 (Analize_Subprogram_Specification): When analyzing a subprogram in which
26286 the type of the first formal is a concurrent type, replace this type
26287 by the corresponding record type.
26288 (Analyze_Subprogram_Body): Undo the previous work.
26289 (Analyze_Procedure_Call): If the call has the form Object.Op, the
26290 analysis of the prefix ends up analyzing the call itself, after which
26291 we are done.

26293 subprogram_specification that returns true if some non
26294 class-wide interface subprogram is found
26295 (New_Overloaded_Entity): Modified to give support to abstract
26296 interface types
26297 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
26298 access to subprograms must be recursive.
26299 (Is_Unchecked_Conversion): Improve the test that recognizes
26300 instantiations of Unchecked_Conversion, and allows them in bodies that
26301 are to be inlined by the front-end. When the body comes from an
26302 instantiation, a reference to Unchecked_Conversion will be an
26303 Expanded_Name, even though the body has not been analyzed yet.
26304 Replace Is_Overriding and Not_Overriding in subprogram_indication with
26305 Must_Override and Must_Not_Override, to better express intent of AI.
26306 (Analyze_Subprogram_Body): If an overriding indicator is given, check
26307 that it is consistent with the overrinding status of the subprogram
26308 at this point.
26309 (Analyze_Subprogram_Declaration): Indicate that a null procedure is
26310 always inlined.
26311 If the subprogram is a null procedure, indicate that it does not need

26314 * sem_disp.adb (Check_Controlling_Type): Give support to entities
26315 available through limited-with clauses.
26316 (Check_Dispatching_Operation): A stub acts like a body, and therefore is
26317 allowed as the last primitive of a tagged type if it has no previous
26318 spec.
26319 (Override_Dispatching_Operation, Check_Dispatching_Operation): Modified
26320 to give support to abstract interface types
26321
26322 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
26323 in the case where the target type is an anonymous access type of an
26324 object or component (that is, when Is_Local_Anonymous_Access is true).
26325 Prevent the special checks for conversions of access discriminants in
26326 the case where the discriminant belongs to a nonlimited type, since
26327 such discriminants have their accessibility level defined in the same
26328 way as a normal component of an anonymous access type.
26329 (Resolve_Allocator): When an allocator's designated type is a class-wide
26330 type, check that the accessibility level of type given in the
26331 allocator's expression or subtype indication is not statically deeper
26332 than the level of the allocator's access type.

26339 types.
26340 (Valid_Tagged_Conversion): The conversion of a tagged type to an
26341 abstract interface type is always valid.
26342 (Valid_Conversion): Modified to give support to abstract interface types
26343 (Resolve_Actuals): Enable full error reporting on view conversions
26344 between unrelated by_reference array types.
26345 The rule for view conversions of arrays with aliased components is
26346 weakened in Ada 2005.
26347 Call to obsolescent subprogram is now considered to be a violation of
26348 pragma Restrictions (No_Obsolescent_Features).
26349 (Check_Direct_Boolean_Operator): If the boolean operation has been
26350 constant-folded, there is nothing to check.
26351 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26352 check on possible violation of restriction No_Direct_Boolean_Operators
26353 until after expansion of operands, to prevent spurious errors when

26363 prefix is a parameterless function that returns an access_to_procedure.
26364 (Transform_Object_Operation): Handle properly function calls of the
26365 form Obj.Op (X), which prior to analysis appear as indexed components.
26366 (Analyze_One_Call): Complete the error notification to help new Ada
26367 2005 users.
26368 (Analyze_Allocator): For an allocator without an initial value, where
26369 the designated type has a constrained partial view, a discriminant
26370 constraint is illegal.
26371
263722005-06-14 Robert Dewar <dewar@adacore.com>
26373
26374 * a-textio.adb (Set_Col): Fix two errors noticed recently, having to

26807 Specialize the former "hpux" section to "hppa hpux", as this is what the

26809 different contents.
26810 (__gnat_adjust_context_for_raise) i386-linux: First version of this
26811 function for this target. Adjust PC by one in the machine context. This
26812 adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but
26813 it is more reliable to do that in the signal handler itself.
26814 (__gnat_install_handler) i386-linux: Set SA_SIGINFO in the sigaction
26815 flags, so that the handler is passed the context structure to adjust
26816 prior to the raise.

26818 SA_SIGINFO sigaction should look like. Call
26819 __gnat_adjust_context_for_raise before actually raising. Cleanup unused
26820 Machine_State_Operations stuff.

28832 calls are now allowed to abstract formal subprograms (which are not
28833 primitive).
28834 Char_Literal_Value field is now a Uint
28835 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28836 compute the actual subtype of the designated object to impose the proper
28837 index constraints.
28838 (Resolve_Selected_Component): Do not insert an access check if the
28839 prefix is an access type: such a node is expanded into an explicit
28840 dereference, on which the access check is performed anyway. Removes
28841 expensive duplicate checks.
28842 (Resolve_Call): Use new flag Is_Obsolescent and field
28843 Obsolescent_Warning so that pragma Obsolescent works on library
28844 subprograms.
28845 Add support for wide wide character type
28846 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28847 value by a warning message.
28848 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28849 as fixed-point, and one of the operands is non-static and universal, it
28850 can only be an illegal exponentiation operation, in which case there is
28851 no real value to retrieve.

28887 overflow in the non-static case.
28888 (Subtypes_Statically_Match): A formal scalar type and its base type do
28889 not statically match.
28890
28891 * sem_util.adb (Collect_Primitive_Operations): Minor change of "/=" to
28892 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28893 subtype).
28894 (Unit_Declaration_Node): Ditto.
28895 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28896 has a packed array type, the prefix has been rewritten into a type
28897 conversion. Determine variable-ness from the converted expression.

28901

28903 Remove ["0A"] from comment, since it can look like a line terminator.
28904 Currently we don't permit this, but this is under discussion by the
28905 ARG, and it is easy enough to use a different example.
28906
28907 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28908 handling UTF-32 encoding for wide wide character.

28916 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28917 notify that constraint error will be raised at run-time
28918 because a null value is assigned to a null-excluding object.
28919 Remove some obsolete declarations and make Char_Code
28920 unsigned.

28927 wrong null-exclusion value by a warning message.
28928 (Enable_Range_Check): Do range check if the prefix is an
28929 explicit dereference whose designated object is an unconstrained array.
28930 Current algorithm for removing duplicate checks is over-eager in this
28931 case.

28946
28947 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28948 defined for subprogram renaming declarations. When set, the field
28949 indicates the defining entity of a corresponding formal subprogram
28950 when the renaming corresponds to a formal subprogram association in an
28951 instantiation.
28952 (Set_Corresponding_Formal_Spec): New procedure to return
28953 Corresponding_Formal_Spec field.
28954 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28955 (which is now a subtype).
28956 Char_Literal_Value field is now a Uint
28957
28958 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28959 pointer to the base of the dispatch table.
28960 Minor changes to comments.
28961 (Controlling_Type): New function for determining the tagged type
28962 associated with a tagged primitive subprogram.
28963 (Expand_Dispatching_Call): Add support for a controlling actual that is
28964 directly a value of type Ada.Tag rather than a tagged object.
28965
28966 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28967 describing the new layout.
28968 (Dispatch_Table): The expander computes the actual array size, allocates
28969 the Dispatch_Table record accordingly, and generates code that displaces
28970 the base of the record after the Typeinfo_Ptr component. The access to
28971 these components is done by means of local functions.
28972 (Offset_To_Top): New function.
28973 (Typeinfo_Ptr): New function.
28974 (Get_TSD): Modified to access the new position of the TSD.
28975 (Set_TSD): Modified to save the TSD in its new position.

28981 * sem_ch12.adb: Add with and use for Sem_Disp.
28982 (Analyze_Associations): Minor change from "=" to "in" for use of
28983 N_Formal_Subtype_Declaration (which is now a subtype).
28984 (Set_Analyzed_Formal): Minor changes from "=" to "in" for uses of
28985 N_Formal_Subtype_Declaration (which is now a subtype).
28986 (Analyze_Formal_Subprogram): Add handling for
28987 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28988 dispatching, setting the controlling status of the formal parameters
28989 and result, and issuing an error if there is no controlling type for
28990 the formal subprogram.
28991 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28992 which is an unclean use of that field, we set the new field
28993 Corresponding_Formal_Spec to make the formal subprogram available to
28994 processing in Analyze_Subprogram_Declaration.
28995 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28996 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28997 Constrained, so that it is is does not statically match its anonymous
28998 base type.
28999
29000 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
29001 abstract formal subprograms in error check for functions returning
29002 abstract types. Set scope of new designator for
29003 a parameterless subprogram, so that it is available when checking the
29004 body for nested subprograms, before full analysis of said body.
29005 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
29006 subprogram only if inner one comes from source.
29007 (Analyze_Function_Call): If the call is given in object notation, the
29008 analysis of the name rewrites the node and analyzes it with the proper
29009 argument list. After analyzing the name, if the call has been rewritten
29010 and the result type is set, no further analysis is needed.
29011 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
29012 mark in function specification, in a context where the formals are
29013 visible and hide outer homographs.
29014
29015 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
29016 as the tagged type for the cases of abstract formal subprograms and
29017 renamings of those. Clean up spec comments.
29018 (Check_Dispatching_Context): Add error message to indicate "abstract
29019 procedure", covering the case of a call to a formal abstract procedure
29020 that has statically tagged operands.
29021 (Check_Dispatching_Call): Check for the case of an actual given by
29022 a tag-indeterminate function call whose type is an ancestor of the
29023 containing call's associated tagged type. This situation can occur
29024 for inherited primitives with function defaults. In this case we
29025 use the tagged type's tag directly as the controlling argument for
29026 the calls.
29027 (Expand_Call): Name change on call to Expand_Dispatch_Call.
29028
29029 * sprint.adb (Sprint_Node_Actual): Split
29030 N_Formal_Subprogram_Declaration into two alternatives for the new

30447 necessary.
30448 (Analyze_Selected_Component): Do not generate an actual subtype for the

30450 needed for constraint checks.
30451 (Analyze_Allocator): If restriction No_Streams is set, then do

30461 when the actual for a formal type with unknown discriminants is a
30462 similar private type whose full view has discriminants.
30463 (Analyze_Object_Declaration): If restriction No_Streams is set, then

30519 procedure Protected_Single_Entry_Call.
30520 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for

30528 at the end of the command line invocation of the compiler, when
30529 compiling a non-Ada file.

30571 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30572 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30573 there is no use of GNAT.Sockets.Constants.
30574 Remove remaining pragma Import for C_Write
30575 Remove C_Read and C_Write from internal implementation unit
30576 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30577 the read and write functions from the system runtime library is fine
30578 on UNIX but won't work under Windows).
30579
30580 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30581 (Check_Selector): Use C_Recv instead of C_Read.
30582 Selectors are the GNAT.Sockets abstraction to perform a select()
30583 call on a set of descriptors. To allow abortion of an ongoing
30584 select operation, some data is written to a dedicated socket that
30585 is always monitored.
30586 Under Windows, the write and read library functions cannot operate
30587 on sockets, so we need to use send and recv instead, which is portable
30588 across all supported platforms.
30589
30590 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30591 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable

30593 fine on UNIX but won't work under Windows).

30639 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30640 sections were just mistakenly ignored. The former is
30641 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30642 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30643 of hpux. This prevents an unwanted definition of the symbol
30644 convert_addresses in adaint.o.

30672 not in verbose mode.
30673 (Force_Deletions): New Boolean flag, defaulted to False
30674 (Delete): Only delete a file if it is writable, and when
30675 Force_Deletions is True.
30676 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30677 (Usage): Line for new switch -f

30684 JM type only if its size matches that of the wrapper. When a size is
30685 prescribed and the field is not aliased, remove the wrapper of a JM
30686 type only if the size is not greater than that of the packed array.

30700 conversion is safe.
30701 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30702 be expandable in place even if the aggregate does not come from source.
30703 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30704 designated object of an allocator in place, rather than building it
30705 first on the stack. The previous scheme forces a full copy of the array,
30706 and may be altogether unsusable if the size of the array is too large

30725 association within aggregates.
30726 Call it in the condition that determines whether the temporary is

30739 (DSA_Implementation_Name): This enumeration lists the possible
30740 implementations of the Partition Communication Subsystem for the
30741 Distributed Systems Annex (DSA). The three available implementations
30742 are the dummy stub implementation (No_DSA), and two versions based on
30743 two different distribution runtime libraries: GARLIC and PolyORB. Both
30744 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30745 technology.
30746 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe

30817 divided by minus one.

30847 of the main unit.
30848 Used to determine whether the body of the instance should be analyzed
30849 immediately after its spec, to make its subprogram bodies available
30850 for front-end inlining.
30851 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30852 constraint is not allowed on the component type (AARM 12.5.3(3))

30867 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30868 or protected type with discriminants, do not constrain the
30869 corresponding record type if the subtype declaration has no
30870 discriminant constraints. This can be the case in source code, or in
30871 the subtype declaration created to rename an actual type within an
30872 instantiation.

308742004-10-26 Ed Schonberg <schonberg@gnat.com>
30875
30876 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30877 different kind of stub (possibly wrong name for file), do not check
30878 for conformance.
30879 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30880 includes call to some function that returns an unconstrained type, do
30881 not inline.
30882
308832004-10-26 Ed Schonberg <schonberg@gnat.com>
30884
30885 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30886 appear in the code for the main unit. Dependencies among units in the
30887 context of the main unit are established when those other units are
30888 compiled. Otherwise spurious elaboration constraints can generate
30889 incorrect elaboration circularities.

30893
30894 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30895 subprogram is called with a parameter that is not an object name. This
30896 situation arises for some cases of illegal code, which is diagnosed
30897 later, and in this case it is wrong to call Is_Aliased, as that might
30898 cause a compiler crash.
30899 (Explain_Limited_Type): Refine previous fix to include
30900 inherited components of derived types, to provide complete information.
30901
30902 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30903 is the prival for a protected object.
30904 It is necessary to mark this entity as a variable, in addition to
30905 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30906 modified to avoid checking the Aliased flag on entities that are not
30907 objects. (Checking that flag for non-objects is erroneous and could
30908 lead to a compiler crash).
30909
309102004-10-26 Robert Dewar <dewar@gnat.com>
30911
30912 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30913 X_Frac = 0.5, then we know that the number X must be positive.
30914 (Succ): Remove the same redundant test, and also fix the primary test
30915 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30916 Minor reformatting
30917 (Decompose): Add fuller comments to spec

31436
31437 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31438 Common_ATCB record. It contains the dynamic level of protected action
31439 nesting for each task. It is needed for checking whether potentially
31440 blocking operations are called from protected operations.
31441 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31442 Detect_Blocking is active or not in the partition.
31443
31444 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
31445 raise Program_Error if called from a protected operation.
31446 (Task_Entry_Call): When pragma Detect_Blocking is active, raise
31447 Program_Error if called from a protected operation.
31448 (Timed_Task_Entry_Call): When pragma Detect_Blocking is active, raise
31449 Program_Error if called from a protected operation.
31450
31451 * s-tassta.adb (Abort_Tasks): When pragma Detect_Blocking is active,

31475
31476 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
31477 insertion of the statement raising Program_Error. The run time
31478 contains the required machinery for handling that.
31479
31480 * sem_util.ads: Change comment associated to procedure
31481 Check_Potentially_Blocking_Operation.
31482 This procedure does not insert a call for raising the exception because
31483 that is currently done by the run time.
31484
31485 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31486
31487 * init.c: Add the global variable __gl_detect_blocking that indicates
31488 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31489 making the pragma available at run time.

31496
31497 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag

31499 Detect_Blocking active forces its effect in the whole partition.
31500
31501 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31502 Detect_Blocking is active and delay is called from a protected
31503 operation.

31509 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
31510 otherwise).

315122004-09-09 Thomas Quinot <quinot@act-europe.fr>
31513
31514 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
31515 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
31516 package.
31517
31518 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31519 (Register_Receiving_Stub): Add Subp_Info formal parameter.

31521 in distribution runtime library.
31522
31523 * sem_ch3.adb (Expand_Derived_Record): Rename to
31524 Expand_Record_Extension.
31525
31526 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31527 primitive operations of potentially distributed object types that have
31528 non-controlling anonymous access formals.
31529
31530 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31531 subprogram.
31532 New implementation of expansion for remote access-to-subprogram types,
31533 based on the RACW infrastructure.
31534 This version of sem_dist is compatible with PolyORB/DSA as well as
31535 GLADE.
31536
31537 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31538 Asynchrronous that applies to a remote access-to-subprogram type, mark
31539 the underlying RACW type as asynchronous.
31540
31541 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31542 __gnat_using_gnu_linker to 1.
31543
31544 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31545 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31546 GNAT.Perfect_Hash_Generators, and remove the empty
31547 GNAT.Perfect_Hash package.
31548
31549 * atree.adb: Minor reformatting
31550
31551 * exp_ch3.adb (Expand_Derived_Record): Rename to
31552 Expand_Record_Extension.
31553 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31554 a component declaration must remain attached at that point in the
31555 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31556 It is therefore necessary to take a copy of the expression when building
31557 the corresponding assignment statement in the init proc.
31558 As a side effect, in the case of a derived record type, we now see the
31559 original expression, without any rewriting that could have occurred
31560 during expansion of the ancestor type's init proc, and we do not need
31561 to go back to Original_Node.
31562
31563 * exp_ch3.ads (Expand_Derived_Record): Rename to
31564 Expand_Record_Extension.
31565
31566 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31568 type.
31569 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31570 New subprograms. Used to create a proxy tagged object for a remote
31571 subprogram. The proxy object is used as the designated object
31572 for RAS values on the same partition (unless All_Calls_Remote applies).
31573 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31574 System.Partition_Interface.Get_Unique_Remote_Pointer.
31575 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31576 Renamed from Add_RAS_*_Attribute.
31577 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31578 subprograms.
31579 New implementation of expansion for remote access-to-subprogram types,
31580 based on the RACW infrastructure.
31581
31582 * exp_dist.ads (Copy_Specification): Update comment to note that this
31583 function can copy the specification from either a subprogram
31584 specification or an access-to-subprogram type definition.
31585
315862004-09-09 Ed Schonberg <schonberg@gnat.com>
31587
31588 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31589 in an instance, between an explicit subprogram an one inherited from a
31590 type derived from an actual.
31591
31592 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31593 add a polling call if the subprogram is to be inlined by the back-end,
31594 to avoid repeated calls with multiple inlinings.
31595
31596 * checks.adb (Apply_Alignment_Check): If the expression in the address
31597 clause is a call whose name is not a static entity (e.g. a dispatching
31598 call), treat as dynamic.
31599

32976 implementation of __gnat_backtrace.
32977
32978 * raise.c: Don't rely on a C mapping of the GNAT_GCC_Exception record
32979 any more. Use accessors instead. This eases maintenance and relaxes
32980 some alignment constraints.
32981 (_GNAT_Exception structure): Remove the Ada specific fields
32982 (EID_For, Adjust_N_Cleanups_For): New accessors, exported by
32983 a-exexpr.adb.

32993
32994 * a-exexpr.adb: Provide new accessors to a GNAT_GCC occurrence, so that
32995 the personality routine can use them and not have to rely on a C
32996 counterpart of the record anymore. This simplifies maintenance and
32997 relaxes the constraint of having Standard'Maximum_Alignment match
32998 BIGGEST_ALIGNMENT.
32999 Update comments, and add a section on the common header alignment issue.

33049 code in the common constrained array cases.
33050
33051 * a-storio.adb: Change implementation to avoid possible alignment

33054
33055 * checks.adb (Apply_Array_Size_Check): Improve these checks by
33056 killing the overflow checks which we really do not need (64-bits is

33830 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33831 includes case of a variable referenced on the left hand side of an
33832 assignment, therefore remove redundant code. Variables and prefixes of
33833 indexed or selected components are now marked as referenced on left
33834 hand side. Warnings are now properly emitted when variables or prefixes
33835 are assigned but not read.
33836
33837 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33838 left hand side referenced variables. Private access types do not
33839 produce the warning "variable ... is assigned but never read".
33840 Add also additional checks to left hand side referenced variables.
33841 Aliased, renamed objects and access types do not produce the warning
33842 "variable ... is assigned but never read" since other entities may read
33843 the memory location.
33844

33935 formals that are obtained from a previous formal package.
33936 (Instantiate_Subprogram_Body): Emit proper error when
33937 generating code and the proper body of a stub is missing.
33938
33939 * sem_ch4.adb (Remove_Address_Interpretations): If the operation still
33940 has a universal interpretation, do the disambiguation here.
33941
33942 * exp_ch4.adb (Expand_N_Type_Conversion,
33943 Expand_N_Unchecked_Type_Conversion): Special handling when target type
33944 is Address, to avoid typing anomalies when Address is a visible integer
33945 type.
33946
33947 * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
33948 to determine whether a subprogram should not be marked Pure, even when

33958 definition found in AI-249.
33959
33960 * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when

33979 discriminated type is not referenced.
33980
33981 * lib-xref.adb (Generate_Reference): A deferred constant completion,
33982 record representation clause or record type discriminant does not

34012 arguments X with a maximum relative error of T'Machine_Epsilon, for X
34013 in -2.0**32 .. 2.0**32.
34014 (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
34015 reduction by the processor, which only uses a 68-bit approximation of
34016 Pi.
34017 (Tan): Always reduce arguments and compute function either using
34018 the processor's fptan instruction, or by dividing sin and cos as needed.

34060 limited view by a package entity that references the first shadow
34061 entity plus the first shadow private entity (required for limited-
34062 private-with clause)

34064 (Remove_Limited_With_Clause): Update the implementation to undo the
34065 new work carried out by Build_Limited_Views.

34268 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
34269 Assert (False).
34270
34271 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
34272 flag processing. This was suppressing required dependencies in
34273 No_Run_Time mode and is not needed since the binder does not generate
34274 references for things in libgnat anyway.
34275
34276 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
34277 warning.

34293 actions if the object is a renaming.
34294
34295 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
34296 Check_Formal_Package_Instance, to determine more precisely when the
34297 formal and the actual denote the same entity.

34300
34301 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
34302
34303 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
34304 corresponding to a private_with must be removed from visibility; it
34305 will be made visible later, just before we analyze the private part of
34306 the package.
34307 (Check_Private_Child_Unit): Allow private_with clauses in public
34308 siblings.
34309 (Install_Siblings): Make visible the private entities of private-withed
34310 siblings.
34311 (Install_Withed_Unit): Do not install the private withed unit if we
34312 are compiling a package declaration and the Private_With_OK flag was
34313 not set by the caller. These declarations will be installed later,
34314 just before we analyze the private part of the package.
34315
34316 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
34317 during the evaluation of the expression that initializes the object,
34318 decorate it with the expected type to avoid cascade errors.
34319 Code cleanup.
34320
34321 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
34322 subprogram we have to install the private_with clauses after its
34323 specification has been analyzed (as documented in AI-262.TXT).
34324
34325 * sem_ch8.adb (Has_Private_With): New function. Determines if the
34326 current compilation unit has a private with on a given entity.
34327 (Find_Direct_Name): Detect the Beaujolais problem described in
34328 AI-262.TXT
34329
34330 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
34331 provides the functionality of the function Is_Ancestor that was
34332 previously available in sem_ch10. It has been renamed to avoid
34333 overloading.
34334
34335 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
34336
343372004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34338

35838 stored discriminants, use its discriminants to constrain parent type,
35839 as is done for non-private derived record types.
35840
35841 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35842 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35843 candidate interpretation in an overloaded call.
35844
35845 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
35846 expression is Null and target type is not an access type (e.g. a

35851 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35852 statement whose right-hand side is an inlined call, save a copy of the
35853 original assignment subtree to preserve enough consistency for
35854 Analyze_Assignment to proceed.
35855
35856 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35857 complete assignment subtree which is now unnecessary, as the expansion
35858 of inlined call has been improved to preserve a consistent assignment
35859 tree. Note_Possible_Modification must be called only
35860 after checks have been applied, or else unnecessary checks will
35861 be generated.
35862
35863 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35864 of explicit dereferences that do not Come_From_Source:
35865 - be selective on cases where we must go back to the dereferenced
35866 pointer (an assignment to an implicit dereference must not be
35867 recorded as modifying the pointer);
35868 - do not rely on Original_Node being present (Analyze_Assignment
35869 calls Note_Possible_Modification on a copied tree).
35870
35871 * sem_warn.adb (Check_References): When an unset reference to a pointer
35872 that is never assigned is encountered, prefer '<pointer> may be null'

36177
36178 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
36179 attribute reference does not denote a subtype, it can be any
36180 expression that has a classwide type, potentially after an implicit
36181 dereference. In particular, the prefix can be a view conversion for
36182 a classwide type (for which Is_Object_Reference holds), but it can
36183 also be a value conversion for an access-to-classwide type. In the
36184 latter case, there is an implicit dereference, and the original node
36185 for the prefix does not verify Is_Object_Reference.

36622 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36623 of non-packed slices, since the dereference action generated by
36624 expansion of the explicit dereference is needed in any case.
36625 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36626 analyze and resolve the rewritten explicit dereference so it is seen
36627 by the expander.
36628 (Insert_Dereference_Action): This procedure is now called only for the
36629 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36630 dereferences that do not come from source (including explicit
36631 dereferences resulting from rewriting implicit ones), but do not
36632 recursively insert a check for the dereference nodes contained within
36633 the check.
36634 (Insert_Dereference_Action): Clarify and correct comment.

37508 Let finish_record_type decide instead.
37509 Don't make a bitfield if the field is to be addressable.
37510 Always set a size for the field if the record is packed, to ensure the

37512 (finish_record_type): During last pass over the fields, clear
37513 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

38017
38018 * rtsfind.adb (Load_Fail): Give full error message in configurable
38019 run-time mode if all_errors mode is set. This was not done in the case

38021 Note if secondary stack unit is used by compiler.
38022
38023 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
38024 ineffective elaborate all pragmas on non-visible packages (this
38025 happened when a renamed subprogram was called). Now the elaborate all
38026 always goes on the package containing the renaming rather than the one
38027 containing the renamed subprogram.

38034 (Eval_String_Literal): Avoid assumption that N_String_Literal node
38035 always references an E_String_Literal_Subtype entity. This may not
38036 be true in the future.
38037

38327 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
38328 aggregate in the parent. Otherwise constants with limited aggregates
38329 are not supported. Add new formal to pass the component type (Ctype).
38330 It is required to call the corresponding IP subprogram in case of
38331 default initialized components.
38332 (Gen_Assign): In case of default-initialized component, generate a
38333 call to the IP subprogram associated with the component.
38334 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
38335 of aggregate with default initialized components.
38336 (Has_Default_Init_Comps): Improve implementation to recursively check

38339 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
38340 to indicate that the initialization call corresponds to a
38341 default-initialized component of an aggregate.
38342 In case of default initialized aggregate with tasks this parameter is
38343 used to generate a null string (this is just a workaround that must be
38344 improved later). In case of discriminants, this parameter is used to
38345 generate a selected component node that gives access to the discriminant
38346 value.
38347
38348 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New

39286
c0040397 39287 * exp_aggr.adb:
65356e64
AC		 39288 (Has_Default_Init_Comps): New function to check the presence of
39289 default initialization in an aggregate.
39290 (Build_Record_Aggr_Code): Recursively expand the ancestor in case of
39291 extension aggregate of a limited record. In addition, a new formal
39292 was added to do not initialize the record controller (if any) during
39293 this recursive expansion of ancestors.
39294 (Init_Controller): Add support for limited record components.
39295 (Expand_Record_Aggregate): In case of default initialized components
39296 convert the aggregate into a set of assignments.
39297
39298 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Update the comment
39299 describing the new syntax.
39300 Nothing else needed to be done because this subprogram delegates part of
39301 its work to P_Precord_Or_Array_Component_Association.
39302 (P_Record_Or_Array_Component_Association): Give support to the new
39303 syntax for default initialization of components.
39304
c0040397 39305 * sem_aggr.adb:
65356e64
AC		 39306 (Resolve_Aggregate): Relax the strictness of the frontend in case of
39307 limited aggregates.
39308 (Resolve_Record_Aggregate): Give support to default initialized
39309 components.
39310 (Get_Value): In case of default initialized components, duplicate
39311 the corresponding default expression (from the record type
39312 declaration). In case of default initialization in the *others*
39313 choice, do not check that all components have the same type.
39314 (Resolve_Extension_Aggregate): Give support to limited extension
39315 aggregates.
39316
c0040397 39317 * sem_ch3.adb:
65356e64
AC		 39318 (Check_Initialization): Relax the strictness of the front-end in case
39319 of aggregate and extension aggregates. This test is now done in
39320 Get_Value in a per-component manner.
39321
39322 * sem_ch4.adb (Analyze_Allocator): Don't post an error if the
39323 expression corresponds to a limited aggregate. This test is now done
39324 in Get_Value.
39325
39326 * sinfo.ads, sinfo.adb (N_Component_Association): Addition of
39327 Box_Present flag.
39328
39329 * sprint.adb (Sprint_Node_Actual): Modified to print an mbox if
39330 present in an N_Component_Association node
39331

43899 a CRC now and not a simple checksum. A CRC uses lower-case hex
cfac6e9f 43900 letters, fixes ambiguity in parsing.

f8e0aa73
AJ		 43952
43953 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43954 for a word. This is currently used only for CRC. In previous version,
43955 the checksum was using a representation with all letter being
43956 upper-case. With the new implementation (using CRC) we do not remove
43957 the 32th bit of the CRC, so we can have an upper-case starting letter
43958 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43959 It is ambigous since the CRC was optional and could be followed by
43960 options like EB, EE. So now this routines uses lower-case letter for
43961 the hexadecimal representation. Strange enough only lower case letters
cfac6e9f 43962 where checked in Scan_ALI (even if this was not a possible case).
f8e0aa73 43963
