1961 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1962 Orig_Prev to Prev in the case where the actual is N_Function_Call or

1965 accessibility level, and based on testing this code is apparently no

4012 (Expand_Dispatching_Call): If this is a call to an instance of the
4013 generic dispatching constructor, the type of the first argument may be
4014 a subtype of Tag, so always use the base type to recognize this case.

4038 instantiated package.

4125 New local subprogram Is_Valid_Remote_Object_Type, replaces
4126 Is_Recursively_Limited_Private.
4127 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4128 non-controlling formals (and the return type, even though this is not
4129 explicit in the standard) must support external streaming.
4130 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4131 as above for of RAS types and RCI subprograms. (The return type is not
4132 checked yet).

4137 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4138 Is_Remote_Call_Interface to identify RACW types in a stable and
4139 consistent way. We used to rely in this predicate on the privateness of
4140 the designated type and its ancestors, but depending on the currently
4141 visible private parts, this caused false negatives. We now uniformly
4142 rely on checks made at the point where the RACW type is declared.

4156 Add missing escaping of all-caps word 'CPP' in error messages.
4157 (Build_Discriminated_Subtype): Do not inherit representation clauses
4158 from parent type if subtype already carries them, because they are

4177 function that returns an access to subprogram and the call has

4201 Entity and Etype to that interpretation, otherwise Entity and Etype may
4202 still refer to an interpretation that was ignored by Add_One_Interp,
4203 in which case would end up with being marked as not overloaded but with

8083 limited ancestor part, initialize controllers of enclosing record
8084 before expanding ancestor aggregate.

8086 code to call Initialize if the component is controlled, and explicit
8087 assignment of null if the component is an access type.
8088
8089 Handle properly aggregates for limited types that appear in object
8090 declarations when the aggregate contains controlled values such as

8111 (Predef_Spec_Or_Body): For interface types generate abstract subprogram
8112 declarations.
8113 (Predefined_Primitive_Bodies): Add body of "=" if the parent of the

8217 the context as the base of the string subtype, to prevent type
8218 mismatches in gigi.
8219 (Resolve_Actuals): If the actual is an entity name, generate a
8220 reference before the actual is resolved and expanded, to prevent
8221 spurious warnings on formals of enclosing protected operations.
8222 (Analyze_Overloaded_Selected_Component): If type of prefix if
8223 class-wide, use visible components of base type.
8224 (Resolve_Selected_Component): Ditto.
8225 (Resolve_Short_Circuit): Detect case of pragma Assert argument
8226 evaluating to False, and issue warning message.
8227

8246
8247 * layout.adb (Resolve_Attribute, case 'Access): If designated type of
8248 context is a limited view, use non-limited view when available. If the
8249 non-limited view is an unconstrained array, this enforces consistency
8250 requirements in 3.10.2 (27).
8251 (Layout_Type): For an access type whose designated type is a limited
8252 view, examine its declaration to determine if it is an unconstrained
8253 array, and size the access type accordingly.

8255 pointers in -gnatdm mode, only if real vms target.
8256

8260 violations of the No_Implicit_Dynamic_Code restriction.
8261 (Resolve_Attribute, case 'Access): If designated type of context is a
8262 limited view, use non-limited view when available. If the non-limited

8264 in 3.10.2 (27).
8265 (Layout_Type): For an access type whose designated type is a limited
8266 view, examine its declaration to determine if it is an unconstrained
8267 array, and size the access type accordingly.

8321 Do not give warning on exception raise in No_Return function
8322
8323 * sem_ch13.adb (Analyze_Record_Representation_Clause): If an inherited
8324 component has two inconsistent component clauses in the same record
8325 representation clause, favor the message that complains about
8326 duplication rather than inconsistency.
8327 Update comments.
8328 (Record_Representation_Clause): Do not warn on missing component
8329 clauses for inherited components of a type extension.
8330 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8331 an overloadable item if it is a pragma that can apply to multiple
8332 overloadable entities (e.g. Inline) because a pragma cannot be on
8333 more than one chain at a time.
8334 (Validate_Unchecked_Conversion): Add code to warn on unchecked
8335 conversion where one of the operands is Ada.Calendar.Time.
8336 (Analyze_Attribute_Definition_Clause): Fix typo in error message.

8350 file name.
8351 (Body_Suffix_Id_Of, Spec_Suffix_Id_Of): new version that takes a name_id
8352 as a parameter. This parameter is in fact always "ada" in all calls, and
8353 we were doing 160560 extra calls to Name_Find to convert it to Name_Ada
8354 while loading a project with 40000 files
8355

8397 for the unit.
8398 (Look_For_Sources): Put the unit exceptions in hash table
8399 Unit_Exceptions
8400 (Get_Unit_Exceptions): Give initial value No_Source to local variable
8401 Other_Part to avoid exception when code is compiled with validity
8402 checking.
8403 (Get_Sources_From_File): Check that there is no directory information
8404 in the file names.
8405 (Look_For_Sources): Check that there is no directory information in the
8406 list of file names in Source_Files.
8407 (Look_For_Sources): In multi-language mode, do not allow exception file
8408 names that are excluded.

AC		 8422 Change Opt.Follow_Links to Opt.Follow_Links_For_Files.
8423 (Opt.Follow_Links_For_Dirs): New flag
8424 (Project_Path_Name_Of): Cache information returned by this routine as
8425 Locate_Regular_File is a costly routine. The code to output a log
8426 information and the effective call to Locate_Regular_File is now
8427 factorized into a routine (code clean-up).
8428 (Parse, Parse_Single_Project): new parameter Current_Dir

8462 * sem_ch10.adb (Check_Private_Child_Unit): A non-private library level
8463 subprogram body that acts as its own spec may not have a non-private
8464 WITH clause on a private sibling.
8465 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8466 child unit is a renaming, create an implicit with_clause on that
8467 parent, and not on the unit it renames, to prevent visibility errors
8468 in the current unit.
8469
84702007-12-13 Ed Schonberg <schonberg@adacore.com>
8471
8472 * sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram
8473 renaming declaration, use the Slocs of the formal parameters from the
8474 declaration of the formal subprogram when creating the formal parameter
8475 entities in the renaming declaration.
8476 (Analyze_Formal_Type_Declaration): Change the placement of the error
8477 message concerning illegal known discriminants. It is now posted on the
8478 type rather than on the first discriminant. This change ensures early
8479 error report.
8480 (Freeze_Subprogram_Body): If the generic subprogram is nested within
8481 the package body that contains the instance, do not generate an
8482 out-of-place freeze node for the enclosing package.
8483 (Collect_Previous_Instantiations): Ignore internal instantiations
8484 generated for formal packages.
8485 (Validate_Derived_Type_Instance): Add a check that when a formal

8503
8504 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid
8505 generation of spurious error if parent is an interface type; caused
8506 because predefined primitive bodies will be generated later by

8509 flag.
8510 (Derive_Subprograms): Handle derivations of predefined primitives

8514 of Related_Interface to Related_Type.
8515 (Record_Type_Declaration): Minor reordering of calls to decorate the

8526 concurrent tagged type prefix should yield a primitive operation.
8527 (Find_Primitive_Operation): Handle case of class-wide types.
8528 (Analyze_Overloaded_Selected_Component): If type of prefix is
8529 class-wide, use visible components of base type.
8530 (Resolve_Selected_Component): Ditto.
8531 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
8532 formal of a generic subprogram. find candidate interpretations by
8533 scanning the list of generic formal declarations.:
8534 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8535 type from a limited_with_clause, and the full view is available, use it
8536 for subsequent semantic checks.
8537 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
8538 (Find_Primitive_Operation): New function.
8539 (Analyze_Overloaded_Selected_Component): insert explicit dereference
8540 only once if several interpretations of the prefix yield an access type.
8541 (Try_Object_Operation): Code and comment cleanup.
8542 (Analyze_Selected_Component): Reorder local variables. Minot comment and
8543 code reformatting. When the type of the prefix is tagged concurrent, a

8554 type has a limited view.
8555 (Find_Direct_Name): Use Namet.Sp.Is_Bad_Spelling_Of function
8556 (Find_Expanded_Name): Use Namet.Sp.Is_Bad_Spelling_Of function
8557 (Analyze_Renamed_Primitive_Operation): new procedure to determine the
8558 operation denoted by a selected component.
8559 (Analyze_Renamed_Entry): Resolve the prefix of the entry name, because
8560 it can be an expression, possibly overloaded, that returns a task or
8561 an access to one.

8564 Gary Dismukes <dismukes@adacore.com>
8565
8566 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8567 requeue statement is dispatching. Do not emit an error when the name is
8568 not an entry and the context is a dispatching select. Add code to
8569 perform subtype conformance between the formals of the current entry
8570 and those of the target interface primitive.
8571 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8572 Timed_Entry_Call): Analyze the triggering statement as the first step of
8573 the processing. If this is a dispatching select, postpone the analysis
8574 of all select statements until the Expander transforms the select. This
8575 approach avoids generating duplicate identifiers after the Expander has
8576 replicated some of the select statements. In case the Expander is
8577 disabled, perform regular analysis.
8578 (Check_Triggering_Statement): New routine.
8579 (Analyze_Requeue): Exclude any interpretations that are not entries when
8580 checking overloaded names in a requeue. Also test type conformance for
8581 matching interpretations rather than requiring subtype conformance at
8582 that point to conform with the RM's resolution rule for requeues.
8583
85842007-12-13 Ed Schonberg <schonberg@adacore.com>
8585
8586 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8587 inherited operation is a defaulted tag-indeterminate call, and there is
8588 a statically tagged actual, use the static tag as a controlling actual
8589 for the defaulted actual.
8590

9470 is already in use or the package where it is declared is in use or is
9471 declared in the current package.

68b72a44
AC		 9481 Add a section on leap seconds control along with two entities used to

9546
9e81dbc7 9547 * a-tags.adb:
68b72a44
AC		 9548 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9549 indirection added to the HT_Link component of the TSD. This is required
9550 to statically allocate the TSD.
9551
9e81dbc7 9552 * a-tags.ads:
68b72a44
AC		 9553 Minor reordering of the declarations in the private part. Required to
9554 add a level of indirection to the contents of the TSD component HT_Link.
9555 This is required to statically allocate the TSD.
9556
9557 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9558 Is_Statically_Allocated set from constant objects.
9559 Do not make exported constants created by the compiler volatile.
9560 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9561 as read-only.
9562
9563 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9564 before returning them.
9565
9566 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9567 public part of the package.
9568 (Make_DT): Move HT_Link component out of the TSD record. For this
9569 purpose Make_DT now declares a separate object that stores the
9570 HT_Link value, and initializes the TSD component with the address
9571 of this new object. The addition of this level of indirection is
9572 required to statically allocate the TSD because the TSD cannot
9573 have variable components.
9574 (Expand_Interface_Conversion): Improve the expanded code.
9575 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9576
9577 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9578 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9579 if we are building static dispatch tables then we must not generate
9580 extra code to register the primitive because the dispatch table will
9581 be built at the end of the library package; otherwise we notify that
9582 we cannot build the static dispatch table.
9583
95842007-09-26 Robert Dewar <dewar@adacore.com>
9585
9586 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9593 tests for controlled type overlay to composites with controlled
9594 components.

9601 for thunks associated with interface types.
9602
9603 * einfo.ads: Improve documentatation of Is_Internal
9604 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9605 associated with interface types.
9606 Extensive comment fixes regarding flags that appear in all entities. The
9607 documentation is now consistent for all such flags (there were a number
9608 of errors in the documentation in this regard).
9609
9610 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9611
9612 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9613 of these procedures are passed a function call that already has
9614 build-in-place actuals (testing new flag
9615 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9616 the case where processing continues.
9617 (Expand_Call): If the call is generated from a thunk body then we
9618 propagate the extra actuals associated with the accessibility
9619 level of the access type actuals.
9620
9621 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9622 of each extra formal of a protected operation to reference the
9623 corresponding extra formal of the subprogram denoted by the
9624 operation's Protected_Body_Subprogram.
9e81dbc7 9625

96412007-09-26 Gary Dismukes <dismukes@adacore.com>
9642
9643 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9644 initialization of a full view. This is moved to
9645 Analyze_Package_Specification.
9646
9647 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9648 preelaborable initialization of a full view in entity loop.
9649 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9650 its child units are use-visible only if they are visible child units.
9651
9652 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9653 whether an expression can be used within a type declaration that
9654 requires preelaborable init.
9655 (Check_Components): Replace inline code that does partial checking for
9656 preelaborable default expressions with call to
9657 Is_Preelaborable_Expression.
9658 (Has_Preelaborable_Initialization): In the case of a generic actual
9659 subtype, (that is, Is_Generic_Actual is True), return the result of
9660 applying Has_Preelaborable_Initialization to the generic actual's base
9661 type.
9662
96632007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9664

9667 (Is_Leap): Move the routine to the scope of Week_In_Year.
9668 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9669 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9670 avoids calling Time_Of and Split, thus making it more efficent.
9671 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9672
9673 * g-calend.ads (Week_In_Year): Change comment to reflect new
9674 implementation.
9675
96762007-09-26 Emmanuel Briot <briot@adacore.com>
9677
9678 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9679 Command_Line): New types
9680 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9681 support for defining how switches can be grouped on a command line (as
9682 is the case for -gnatw... for GNAT), and how simple switches can be
9683 used as aliases for more complex switches (-gnatwa is same as
9684 -gnatwbcef...)
9685 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9686 (Start, Current_*): New subprograms
9687 Added support for parsing an array of strings in addition to the real
9688 command line.
9689 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9690 be moved from the body to the private part of the spec.
9691 (*): All subprograms now have an extra parameter with default value to
9692 specify which parser should be used. For backward compatibility, it
9693 defaults to parsing the command line of the application. They were also
9694 modified to properly handle cases where each of the argument does not
9695 start at index 1 (which is always true for Ada.Command_Line, but not
9696 when processing any Argument_List).
9697 (Free): New subprogram
9698 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9699 Argument): New subprograms
9700 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9701 special characters like ':', '=',... are now handled in a single place,
9702 which makes the code more extensible eventually.
9703 (Getopt, Full_Switch): When the switch was returned as part of the
9704 special character '*', make sure it is prepended by the switch character
9705 ('-' in general), so that the application knows whether "foo" or "-foo"
9706 was specified on the command line.
9707
97082007-09-26 Florian Villoing <villoing@adacore.com>
9709
9710 * g-dirope.adb (Remove_Dir): In case we are removing directories
9711 recursively, make sure that if an exception is raised during the
9712 processing, the current working directory is reset to its initial
9713 value before propagating the exception.
9714
97152007-09-26 Vincent Celier <celier@adacore.com>
9716
9717 * gnatbind.adb: If there are several ALI files specified and there is
9718 a main program to bind, the first ALI is expected to contain the main
9719 subprogram and the names of the binder generated files will be derived
9720 from the first ALI file name.
9721 (Gnatbind): Fix insertion character in invocation of Error_Msg
9722
97232007-09-26 Vincent Celier <celier@adacore.com>
9724

9727
97282007-09-26 Ed Schonberg <schonberg@adacore.com>
9729

9731 information about each of its index types, following the type
9732 reference for its component type.

9762 attributes for gprbuild. No impact on GNAT tools.
9763
9764 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9765 process configuration attributes: this is done in Prj.Nmsc.Check.
9766 (Recursive_Process): Make a full copy of packages inherited from project
9767 being extended, instead of a shallow copy.
9768 (Process_Project_Tree_Phase_1): New procedure

9770 (Process): Implementation now uses the two new procedures
9771
9772 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9773 from the project config, not the tree config that no longer exists.

10100
10101 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10102 create an abstract subprogram in the case of 'Input. For 'Output we now
10103 create a real spec/body when the type is abstract, since it can
10104 potentially be called.
10105 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10106 body for 'Output when the type is abstract (only the creation of the
10107 body for 'Input is excluded when the type is abstract).
10108 (Stream_Operation_OK): Add an additional condition in the return
10109 statement, so that False will be returned for TTS_Stream_Input if the
10110 associated tagged type is an abstract extension. Add comments for
10111 return statement.
10112 (Expand_N_Object_Declaration): For the case of a shared passive
10113 variable, insert init proc call only after the shared variable
10114 procedures have been processed, because the IP call needs to undergo
10115 shared passive variable reference expansion, which requires these
10116 procedures to be available (and elaborated).

10126 given a box association, the type of the component is discriminated,
10127 and the value of the discriminant is the discriminant of the enclosing
10128 type, retrieve its value from the aggregate itself, where it must have
10129 been supplied.
10130
10131 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10132 to remove other spurious ambiguities on arithmetic operations involving
10133 literals and addresses, on systems where Address is a visible integer
10134 type, when the operator is called in functional notation.
10135 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10136 is legal when the types match, even if the operation is currently
10137 hidden.

ab6328d0
AC		 10647 Suppress unmodified in-out parameter warning in some cases
10648 This patch is a also fairly significant change to the way suppressible
10649 checks are handled.
10650
10651 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10652 needed for access to concurrent record types generated by the expander.
10653 (Generate_Range_Check): When generating a temporary to capture the
10654 value of a conversion that requires a range check, set the type of the
10655 temporary before rewriting the node, so that the type is always
10656 properly placed for back-end use.
10657 (Apply_Float_Conversion_Check): Handle case where the conversion is
10658 truncating.
10659 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10660 for a protected type in order to examine its discriminants.

ab6328d0
AC		 10668 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10669 tests optimized out.
10670
10671 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10672 (Get_Allocator_Final_List): For the case of an anonymous access type
10673 that has a specified Associated_Final_Chain, do not go up to the
10674 enclosing scope.
10675 (Expand_N_Type_Conversion): Test for the case of renamings of access
10676 parameters when deciding whether to apply a run-time accessibility
10677 check.
10678 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10679 aggregate code before allocator, and ahead of declaration for
10680 temporary, to prevent access before elaboration when the allocator is
10681 an actual for an access parameter.
10682 (Expand_N_Type_Conversion): On an access type conversion involving an
10683 access parameter, do not apply an accessibility check when the
10684 operand's original node was an attribute other than 'Access. We now
10685 create access conversions for the expansion of 'Unchecked_Access and
10686 'Unrestricted_Access in certain cases and clearly accessibility should
10687 not be checked for those.
10688
10689 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10690 includes a type conversion of a packed component that has been expanded,
10691 recover the original expression for the object, and use this expression
10692 in the post-call assignment statement, so that the assignment is made
10693 to the object and not to a back-end temporary.
10694 (Freeze_Subprogram): In case of primitives of tagged types not defined
10695 at the library level force generation of code to register the primitive
10696 in the dispatch table. In addition some code reorganization has been
10697 done to leave the implementation clear.
10698 (Expand_Call): When expanding an inherited implicit conversion,
10699 preserve the type of the inherited function after the intrinsic
10700 operation has been expanded.
10701
10702 * exp_ch2.ads, exp_ch2.adb
10703 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10704 of an entry formal appearing in an assignment statement does not assign
10705 to the formal.
10706 (Expand_Current_Value): Instead of calling a routine to determine
10707 whether the prefix of an attribute reference should be optimized or
10708 not, prevent the optimization of such prefixes all together.
10709
10710 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10711 component whose prefix is known to be of an access type is an implicit
10712 dereference and does not assign to the prefix.

10715 Robert Dewar <dewar@adacore.com>

10718 itype is visited, make an entry into table to link associated node and
10719 new itype.
10720 Add comments and correct harmless error in Build_NCT_Hash_Tables
10721 (Array_Aggr_Subtype): Associate each itype created for an index type to
10722 the corresponding range construct, and not to the aggregate itself. to
10723 maintain a one-to-one correspondence between itype and its associated
10724 node, to prevent errors when complex expression is copied.
10725 Fix mishandling of multiple levels of parens
10726
10727 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10728 treatment of limited views uniform for all visible declarations in a
10729 limited_withed package.
10730 (New_Copy_Tree): If hash table is being used and itype is visited,
10731 make an entry into table to link associated node and new itype.
10732 (Resolve_Record_Aggregate): Do not add an others box association for a
10733 discriminated record component that has only discriminants, when there
10734 is a box association for the component itself.
10735
10736 * par-ch4.adb: Fix mishandling of multiple levels of parens

10778 (Set_Related_Interaface/Related_Interface): Allow the use of this
10779 attribute with constants.
10780 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10781 Warn on duplicate pragma Preelaborable_Initialialization
10782
10783 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10784 generation of a freezing node to ensure proper management of null
10785 excluding access types in the backend.
10786 (Create_Extra_Formals): Test base type of the formal when checking for
10787 the need to add an extra accessibility-level formal. Pass the entity E
10788 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10789 originally being done in a couple of cases), to ensure that the
10790 Extra_Formals list gets set on the entity E when the first entity is
10791 added.
10792 (Conforming_Types): Add missing calls to Base_Type to the code that
10793 handles anonymous access types. This is required to handle the
10794 general case because Process_Formals builds internal subtype entities
10795 to handle null-excluding access types.
10796 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10797 functions that need it, even when not marked Requires_Overriding.
10798 Improve warnings for in out parameters
10799 (Analyze_Function_Return): Warn for disallowed null return
10800 Warn on return from procedure with unset out parameter
10801 Ensure consistent use of # in error messages
10802 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10803 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10804 the implicit conversion of the expression done for anonymous access
10805 types. This is required to generate the code of the null excluding
10806 check (if required).
10807
10808 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10809 A formal parameter is never publicly referenceable outside of its body.
10810 (Check_References): For an unreferenced formal parameter in an accept
10811 statement, use the same warning circuitry as for subprogram formal
10812 parameters.
10813 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10814 Output_Unreferenced_Messages, containing the part of that routine that
10815 is now reused for entry formals as described above.
10816 (Goto_Spec_Entity): New function
10817 (Check_References): Do not give IN OUT warning for dispatching operation
10818 Improve warnings for in out parameters
10819 (Test_Ref): Check that the entity is not undefinite before calling
10820 Scope_Within, in order to avoid infinite loops.
10821 Warn on return from procedure with unset out parameter
10822 Improved warnings for unused variables

10827
10828 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10829 (Expand_N_Attribute_Reference): Further unify the handling of the
10830 three forms of access attributes, using common code now for all three
10831 cases. Add a test for the case of applying an access attribute to
10832 an explicit dereference when the context is an access-to-interface
10833 type. In that case we need to apply the conversion to the prefix
10834 of the explicit dereference rather than the prefix of the attribute.
10835 (Attribute_Version, UET_Address): Set entity as internal to ensure
10836 proper dg output of implicit importation.
10837 (Expand_Access_To_Type): Removed.
10838 (Expand_N_Attribute_Reference): Merge the code from the three cases
10839 of access attributes, since the processing is largely identical for
10840 these cases. The substantive fix here is to process the case of a
10841 type name prefix (current instance case) before handling the case
10842 of interface prefixes.

10848
10849 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10850 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10851 type that is an anonymous access to controlled object, establish
10852 an associated finalization chain to avoid corrupting the global
10853 finalization list when a dynamically allocated object designated
10854 by such a component is deallocated.
10855 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10856 functions that need it, even when not marked Requires_Overriding.
10857 (Initialize_Tag): Replace call to has_discriminants by call to
10858 Is_Variable_Size_Record in the circuitry that handles the
10859 initialization of secondary tags.
10860 (Is_Variable_Size_Record): New implementation.
10861 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10862 Suppress_Initialization pragma for a derived type.
10863 (Is_Variable_Size_Record): New subprogram.
10864 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10865 initial version of this routine and also fixes problems causing
10866 incomplete initialization of the table of interfaces.
10867 (Build_Init_Procedure): Improve the generation of code to initialize the
10868 the tag components of secondary dispatch tables.
10869 (Init_Secondary_Tags): New implementation that simplifies the previous
10870 version of this routine.
10871 (Make_DT): Add parameter to indicate when type has been frozen by an
10872 object declaration, for diagnostic purposes.
10873 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10874 diagnose attemps to freeze a subprogram when some untagged type of its
10875 profile is a private type whose full view has not been analyzed yet.
10876 (Freeze_Array_Type): Generate init proc for packed array if either
10877 Initialize or Normalize_Scalars is set.
10878 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10879 constructing the new profile, copy the null_exclusion indicator for each
10880 parameter, to ensure full conformance of the new body with the spec.
10881
10882 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10883 Create wrappers for constructor functions that need it, even when not
10884 marked Requires_Overriding.
10885 (Covers): Handle properly designated types of anonymous access types,
10886 whose non-limited views are themselves incomplete types.
10887 (Add_Entry): Use an entity to store the abstract operation which hides
10888 an interpretation.
10889 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10890 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10891 initialization aggregate.
10892 (Function_Interp_May_Be_Hidden): Rename to
10893 Function_Interp_Has_Abstract_Op.
10894 (Has_Compatible_Type): Remove machinery that skips interpretations if
10895 they are labeled as potentially hidden by an abstract operator.
10896 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10897 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10898 (Write_Overloads): Output the abstract operator if present.
10899 (Add_Entry): Before inserting a new entry into the interpretation table
10900 for a node, determine whether the entry will be disabled by an abstract
10901 operator.
10902 (Binary_Op_Interp_May_Be_Hidden): New routine.
10903 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10904 aggregate.
10905 (Function_Interp_May_Be_Hidden): New routine.
10906 (Has_Compatible_Type): Do not consider interpretations hidden by
10907 abstract operators when trying to determine whether two types are
10908 compatible.
10909 (Has_Hidden_Interp): New routine.
10910 (Set_May_Be_Hidden_Interp): New routine.
10911 (Write_Overloads): Write the status of flag May_Be_Hidden.

10915
10916 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10917 types declared in the declarative part of a nested package body or in
10918 the proper body of a stub.
10919 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10920 of the same dispatch table slot to renamed primitives.
10921 (Make_Select_Specific_Data_Table): Handle private types.
10922 (Tagged_Kind): Handle private types.
10923 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10924 output of implicit importation and exportation.
10925 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10926 first formal of the thunk is always associated with the controlling
10927 type. In addition perform the following code cleanup: remove formal
10928 Thunk_Alias which is no longer required, cleanup evaluation of the
10929 the controlling type, and update the documentation.
10930 Replace occurrence of Default_Prim_Op_Count by
10931 Max_Predef_Prims. Addition of compile-time check to verify
10932 that the value of Max_Predef_Prims is correct.
10933 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10934 (Make_DT): Add parameter to indicate when type has been frozen by an
10935 object declaration, for diagnostic purposes.
10936 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10937 construction of statically allocated dispatch tables.
10938 (Make_DT): In case of library-level tagged types export the declaration
10939 of the primary tag. Remove generation of tags (now done by Make_Tags).
10940 Additional modifications to handle non-static generation of dispatch
10941 tables. Take care of building tables for asynchronous interface types
10942 (Make_Tags): New subprogram that generates the entities associated with
10943 the primary and secondary tags of Typ and fills the contents of Access_
10944 Disp_Table. In case of library-level tagged types imports the forward
10945 declaration of the primary tag that will be declared later by Make_DT.
10946 (Expand_Interface_Conversion): In case of access types to interfaces
10947 replace an itype declaration by an explicit type declaration to avoid
10948 problems associated with the scope of such itype in transient blocks.

10953
9e81dbc7 10954 * exp_util.ads, exp_util.adb:
ab6328d0
AC		 10955 This patch replaces a number of occurrences of explicit tests for N_Null
10956 with calls to Known_Null. This improves tracking of null values, since
10957 Known_Null also catches null constants, and variables currently known to
10958 be null, so we get better tracking.
10959 (Ensure_Defined): create an itype reference only in the scope of the
10960 itype.
10961 (Side_Effect_Free): A selected component of an access type that
10962 denotes a component with a rep clause must be treated as not
10963 side-effect free, because if it is part of a linked structure its
10964 value may be affected by a renaming.
10965 (Expand_Subtype_From_Expr): For limited objects initialized with build
10966 in place function calls, do nothing; otherwise we prematurely introduce
10967 an N_Reference node in the expression initializing the object, which
10968 breaks the circuitry that detects and adds the additional arguments to
10969 the called function. Bug found working in the new patch for statically
10970 allocated dispatch tables.
10971 (Is_Library_Level_Tagged_Type): New subprogram.
10972 (Remove_Side_Effects): If the expression of an elementary type is an
10973 operator treat as a function call.
10974 (Make_Literal_Range): If the index type of the array is not integer, use
10975 attributes properly to compute the constraint on the resulting aggregate
10976 which is a string.
10977
10978 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10979 class-wide type whose base type is an incomplete private type, leave
10980 class-wide type unfrozen so that freeze nodes can be generated
10981 properly at a later point.
10982 (Freeze_Entity, array case): Handle case of pragma Pack and component
10983 size attributre clause for same array.

11031 can be used by gprbuild.
11032 Major update of the Project Manager and of the project aware tools,

11630 derived type with interface progenitors use the analyzed formal as the
11631 parent of the actual, to create renamings for all the inherited
11632 operations in Derive_Subprograms.
11633 (Collect_Previous_Instances): new procedure within of
11634 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11635 unit being loaded, to ensure that the generation of global symbols is
11636 consistent in different compilation modes.
11637 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11638 takes progenitor types into account.
11639 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11640 traversing over the primitives of the formal and actual types to locate
11641 any abstract subprograms of the actual type that correspond to a
11642 nonabstract subprogram of the formal type's ancestor type(s), and issue
11643 an error if such is found.
11644 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

11646 Remove bogus guard around calls to Inherit_Context.

11656 parameter to determine whether operation applies to the prefix.
11657 (Complete_Object_Operation): If actual has an access type and
11658 controlling formal is not an in_parameter, reject the actual if it is
11659 an access_to_constant type.
11660 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11661 type, the candidate operations are found in the scope of declaration of
11662 the type, because the type has no primitive subprograms.
11663 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11664 a private extension, only examine visible components before trying to
11665 analyze as a prefixed call.
11666 Change Entity_List to Type_To_Use, for better readability.
11667 (Has_Fixed_Op): Use base type when checking whether the type of an

11676 formal At_Any_Place indicating, when True, that we want to test for
11677 availability of the stream attribute at any place (as opposed to the
11678 current visibility context only).
11679 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11680 purpose of enforcing E.2.2(8) only if it is not available at any place.
11681 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11682 when checking the legality of an extension aggregate in a preelaborable
11683 package. Treat the literal null as a valid default expression in a
11684 component declaration for a type with preelaborable initialization.
11685 A limited interface is a legal progenitor for the designated type of a
11686 remote access to class-wide type.

11698 mark the full view as referenced, to prevent spurious warnings.
11699 (Find_Selected_Component, Has_Components): Handle properly non-limited
11700 views that are themselves incomplete types.
11701 Handle interfaces visible through limited-with clauses.
11702 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a

11714 the allocator is not a coextension.
11715 (Resolve): Skip an interpretation hidden by an abstract operator only
11716 when the type of the interpretation matches that of the context.
11717 (Resolve): When looping through all possible interpretations of a node,
11718 do not consider those that are hidden by abstract operators.
11719 (Resolve_Actuals): When verifying that an access to class-wide object
11720 is an actual for a controlling formal, ignore anonymous access to
11721 subprograms whose return type is an access to class_wide type.
11722 (Resolve_Slice): If the prefix of the slice is a selected component
11723 whose type depends on discriminants, build its actual subtype before
11724 applying range checks on the bounds of the slice.
11725 (Valid_Conversion): In an instance or inlined body, compare root types,
11726 to prevent anomalies between private and public views.
11727 (Resolve): Improve error message for ambiguous fixed multiplication
11728 expressions that involve universal_fixed multiplying operations.

12901 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12902 applicable to types that have the With_Type flag set. Returns the
12903 non-limited view of the type, if available, otherwise the type itself.
12904 For class-wide types, there is no direct link in the tree, so we have
12905 to retrieve the class-wide type of the non-limited view of the Etype.
12906 New attributes Static_Initialization and Static_Elaboration_Desired.
12907 Remove the pragma Thread_Body, and the associated flag
12908 Is_Thread_Body in entities, and all related code.
12909 (Suppress_Value_Tracking_On_Call): New flag

12921 (Original_Access_Type): Remove, not needed.
12922 (Root_Type): Handle properly subtypes of class-wide-types.
12923 Update comments.
12924
12925 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12926 class-wide types visible through limited-with clauses.
12927 (Try_Primitive_Operation): When examining all primitive operations of a
12928 tagged type, do not consider subprograms labeled as hidden unless they
12929 belong to a private generic type with a tagged parent.
12930 (Try_Object_Operation): Extensive rewriting, to handle properly various
12931 overloading cases, when several ancestors may have class-wide operations
12932 that are possible candidates, and when the overloaded functions return
12933 array types and have defaulted parameters so that the call may be
12934 interpreted as an indexing.
12935 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12936 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12937 successive actuals before analyzing the call itself.
12938 (Try_Primitive_Operation): A primitive operation is compatible with the
12939 prefix if the prefix has a synchronized type and the type of the formal
12940 is its corresponding record, as can be the case when the primitive
12941 operation is declared outside of the body of the type.
12942 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12943 perform homonym traversal, looking for class-wide operation matches
12944 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12945 access parameters are now restricted to anonymous access types.
12946 (Mark_Allocator): An allocator with a discriminant association parent is
12947 a coextension.
12948 (Try_One_Prefix_Interpretation): If the type of the object is
12949 incomplete, as can be happen when it is a limited view obtained through
12950 a limited_with_clause, the selected component is not part of a prefixed
12951 call.
12952 (Complete_Object_Operation): Diagnose properly an object that is not
12953 aliased when the corresponding controlling formal is an access
12954 parameter.
12955 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12956 ambiguous calls in prefixed notation, where two primitives differ only
12957 in that the controlling argument of one is an access parameter.
12958
12959 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12960 whether a function that returns an unconstrained type can be inlined.
12961 (Process_Formals): Diagnose properly the illegal use of an incomplete
12962 type in the profile of an access_to_subprogram declaration.
12963 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12964 operations are attached to the corresponding record.
12965 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12966 When processing a primitive of a concurrent type which implements an
12967 interface change the type of all controlling formals to that of the
12968 corresponding record type.
12969 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12970 to determine the tagged type to which a primitive belongs.
12971 (Check_Conventions): Capture condition to ignore a primitive operation
12972 (which is shared between the loop in Check_Conventions and the one in
12973 Check_Convention) in a new local function Skip_Check.
12974 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12975 confusion with Check_Conventions' own Prim_Op local variable.
12976 (Create_Extra_Formals): Test for a tagged result type rather than a
12977 controlling result when determining whether to add a BIP_Alloc_Form
12978 formal and a BIP_Final_List formal to the function.
12979 (Check_Conformance); For parameters that are anonymous access types,
12980 subtype conformance requires that the not null and the constant
12981 indicators must match
12982 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12983 to retrieve the appropriate type when processing a concurrent type
12984 declared within a generic. Minor comment reformatting. Change invocation
12985 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12986 mitive.
12987 (Analyze_Subprogram_Body): If the return type of a function is an
12988 anonymous access to the limited view of a class-wide type, and the
12989 non-limited view of the type is available, update the type of the
12990 function so that code can be generated.
12991 (Process_Formals): In case of access-subtype itype whose designated
12992 type is also an itype (situation that happens now with access to
12993 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12994 attribute to avoid backend problems.
12995 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12996 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12997 anonymous types' designated types are same before testing
12998 Subtypes_Statically_Match.
12999 (Create_Extra_Formals): Test for a named access parameter that is a
13000 controlling formal as an additional condition for adding an
13001 accessibility level formal. This can occur in the subp type created for
13002 dispatching calls in Expand_Dispatching_Call, and allows calling
13003 Create_Extra_Formals from that procedure rather than special-casing the
13004 extra formals there.
13005 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13006 when the function has a controlling result.
13007 (Check_Returns): Add much more knowledge of the optimization of local
13008 raise statements to gotos, to retain proper warnings in this case.
13009 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13010 nodes when looking for last statement.
13011
13012 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13013 class-wide types visible through limited with clauses.
13014 (Add_One_Interp): If the operands are anonymous access types, the
13015 predefined operator on universal_access is immediately visibles
13016 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13017 other anonymous access types.
13018 (Disambiguate): Take into account CIL convention.
13019 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13020
130212007-06-06 Robert Dewar <dewar@adacore.com>
13022
13023 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13024 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13025 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13026 Fix lower bound of tables.
13027 Add rep clauses.
13028
13029 * nlists.adb: Ditto.
13030 (Prev_Node, Next_Node): Change index type to Int so that it properly
13031 covers the range First_Node_Id - 1 up.

13037
9e81dbc7 13038 * exp_aggr.ads, exp_aggr.adb:
ec11296f
AC		 13039 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13040 in extension aggregates.
13041 (Flatten): Other conditions being met, an aggregate is static if the
13042 low bound given by component associations is different from the low
13043 bound of the base index type.
13044 (Packed_Array_Aggregate_Handled): If the component type is itself a
13045 packed array or record, the front-end must expand into assignments.
13046 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13047 Init_Pr, instead of Ancestor_Is_Expression.
13048 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13049 coextension chain root, either generate a list controller or use the
13050 already existing one.
13051 (Static_Array_Aggregate): New procedure to construct a positional
13052 aggregate that can be handled by the backend, when all bounds and
13053 components are compile-time known constants.
13054 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13055 types covering interface types into assignments.
13056 (Replace_Type): move to Build_Record_Aggr_Code.
13057 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13058 interface type, convert to the definite type of the aggregate itself,
13059 so that needed components are visible.
13060 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13061 components and the context is an extended return statement do not
13062 create a transient block for it, to prevent premature finalization
13063 before the return is executed.
13064 (Gen_Assign): Do not generate a call to deep adjust routine if the
13065 component type is itself an array of controlled (sub)-components
13066 initialized with an inner aggregate.
13067 (Component_Check): New name for Static_Check. This name is now more
13068 appropriate, and documentation is added which was missing.
13069 (Component_Check): Add test for bit aligned component value
13070 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13071 Tagged_Comps, name is more appropriate given added function below.
13072 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13076 Robert Dewar <dewar@adacore.com>
13077
13078 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13079 Terminated: Add unchecked type conversion from System.Address to
13080 System.Tasking.Task_Id when calling the predefined primitive
13081 _disp_get_task_id.
13082 Disable new Ada 05 accessibility check for JVM.NET targets, which
13083 cannot be implemented in a practical way.
13084 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13085 the sources always references the tag of the actual object. Therefore,
13086 if 'Tag is applied in the sources to class-wide interface objects we
13087 generate code that displaces "this" to reference the base of the object.
13088 (Expand_N_Attribute_Reference, case Size): Return specified size if
13089 known to front end.
13090 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13091 has code that displaces the pointer of the object to manage interface
13092 types. However this code must not be executed when the prefix is a
13093 subprogram. This bug caused the wrong expansion of the internally
13094 generated assignment that fills the dispatch table when the primitive
13095 is a function returning a class-wide interface type.
13096 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13097 Set_Attribute_Name for Name_Unaligned_Valid.
13098
130992007-06-06 Ed Schonberg <schonberg@adacore.com>
13100 Gary Dismukes <dismukes@adacore.com>
13101
13102 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13103 If the initialization is the equivalent aggregate of the initialization
13104 procedure of the type, do not remove it.
13105 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13106 initialized to null from having their expression reset to empty and
13107 note this exception in the comment.
13108

13111 Ed Schonberg <schonberg@adacore.com>
13112 Gary Dismukes <dismukes@adacore.com>
13113
13114 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13115 Add "with" and "use" clauses for Sem_Attr.
13116 (Expand_Current_Value): Do not replace occurences of attribute
13117 references where the prefix must be a simple name.
13118
13119 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13120 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13121 Attribute_Requires_Simple_Name_Prefix.
13122 (Name_Modifies_Prefix): Body of new function.
13123 (Requires_Simple_Name_Prefix): Body of new function.
13124 (Resolve_Attribute, case Access): Improve error message for case of
13125 mismatched conventions.
13126 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13127 incomplete type.
13128 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13129 constrained subtype for a nominal unconstrained type, use its base type
13130 to check for conformance with the context.
13131 (Resolve_Attribute): Remove test of the access type being associated
13132 with a return statement from condition for performing accessibility
13133 checks on access attributes, since this case is now captured by
13134 Is_Local_Anonymous_Access.
13135 (Analyze_Access_Attribute): Set Address_Taken on entity
13136 (Analyze_Attribute, case Address): Set Address_Taken on entity
13137 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13138 validating an access attribute whose prefix is a current instance.
13139 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13140 applied to dispatching operations, if freezing is required then we set
13141 the attribute Has_Delayed_Freeze in the prefix's entity.
13142 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13143 current scope if access of local subprogram taken
13144 (Analyze_Access_Attribute): Check legality of self-reference even if the
13145 expression comes from source, as when a single component association in
13146 an aggregate has a box association.
13147 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13148 the prefix if it is a protected operation and the attribute is
13149 Unrestricted_Access.
13150 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13151 reference to the base type of the context, to force a constraint check
13152 when the context is an access subtype with an explicit constraint.
13153 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13154 node is rewritten as an interface conversion. leave unanalyzed after
13155 resolution, to ensure that type checking against the context will take
13156 place.
13157

13159 Javier Miranda <miranda@adacore.com>
13160 Robert Dewar <dewar@adacore.com>
13161
13162 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13163 wrapper when the full view of the controlling type of an inherited
13164 function that dispatches on result implements interfaces.
13165 (Expand_N_Object_Declaration): In cases where the type of the
13166 declaration is anonymous access, create finalization list for it.
13167 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13168 if the object has no explicit initialization, to match description of
13169 functionality of pragam Persistent_BSS.
13170 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13171 new function to build static aggregates, to replace initialization call
13172 when static initialization is desired.
13173 (Freeze_Type): Generate a list controller for an access type whenever
13174 its designated type has controlled anonymous access discriminants.
13175 (Build_Equivalent_Aggregate): New procedure to compute a static
13176 aggregate to be used as default initialization for composite types,
13177 instead of a generating a call to the initialization procedure for the
13178 type.
13179 (Build_Initialization_Call): When available, replace a call to the
13180 initialization procedure with a copy of the equivalent static aggregate
13181 for the type.
13182 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13183 declarations for objects of a class-wide interface type, rather than
13184 just identifiers, to prevent visibility problems.
13185 (Expand_N_Object_Declaration): When expanding the declaration for an
13186 object of a class-wide interface type, preserve the homonym chain of
13187 the original entity before exchanging it with that of the generated
13188 renaming declaration.
13189 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13190 active, because there is no way to handle the exception.
13191 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13192 to do a minimum decoration of the Access_Disp_Table list.
13193 (Expand_Record_Controller): Avoid the addition of the controller between
13194 the component containing the tag of a secondary dispatch table and its
13195 adjacent component that stores the offset to the base of the object.
13196 This latter component is only generated when the parent type has
13197 discriminants ---documented in Add_Interface_Tag_Components).
13198 (Apply_Array_Size_Check): Removed, no longer needed.
13199 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13200 components, create a Master_Entity for it only if it contains tasks.
13201 (Build_Init_Procedure): Suppress the tag assignment compiling under
13202 no run-time mode.
13203 (Freeze_Record_Type): Remove code associated with creation of dispatch
13204 table.
13205 (Init_Secondary_Tags): Update type of actuals when generating calls to
13206 Ada.Tags.Set_Offset_To_Top
13207 (Stream_Operation_OK): Disable use of streams compiling under no
13208 run-time mode
13209 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13210 if Has_Init_Expression set.
13211 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13212 Register_Primitive, which provides the same functionality.
13213 (Requires_Init_Proc): Return false in case of interface types.
13214 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13215 cleanup the code.
13216 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13217 is always associated with a predefined primitive because the internal
13218 entities associated with interface types are not predefined primitives.
13219 Therefore, the call to Is_Internal is replaced by a call to the
13220 function Is_Predefined_Dispatching_Operation.
13221 (Make_Eq_If): When generating the list of comparisons for the
13222 components of a given variant, omit the controller component that is
13223 present if the variant has controlled components.

13227 Bob Duff <duff@adacore.com>
13228
13229 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13230 handle the creation of finalization lists and calls for nested
13231 coextensions when the root of the chains is part of a return statement.
13232 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13233 Finalization.
13234 (Expand_Record_Equality): Skip components that are interface types.
13235 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13236 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13237 with Rewrite_Coextension. Change the condition for detecting coextension
13238 root nodes.
13239 (Is_Local_Access_Discriminant): Removed.
13240 (Rewrite_Coextension): New routine which rewrites a static coextension
13241 as a temporary and uses its unrestricted access in the construction of
13242 the outer object.
13243 (Complete_Coextension_Finalization): New routine. Generate finalization
13244 attachment calls to all delayed coextensions.
13245 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13246 the allocator is not a coextension itself and has delayed coextensions.
13247 If the current allocator is controlled, but also a coextension, delay
13248 the generation of the finalization attachment call.
13249 Rename local variable "Node" to "Nod" in order to avoid confusion with
13250 "Elists.Node".
13251 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13252 limited types that are not inherently limited. Such an allocator is
13253 illegal, but is generated by the expander for a return statement, to
13254 copy the result onto the secondary stack. This is the only case where a
13255 limited object can be copied. Generate code to displace the pointer
13256 to the object if the qualified expression is a class-wide interface
13257 object. Such displacement was missing and hence the copy of the object
13258 was wrong.
13259 (Apply_Accessibility_Check): Handle allocated objects initialized in
13260 place.
13261 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13262 and Expand_Allocator_Expression. Allocating class-wide interface objects
13263 this routine displaces the pointer to the allocated object to reference
13264 the component referencing the corresponding secondary dispatch table.
13265 Expand_Allocator_Expression): Add missing support to allocate class-wide
13266 interface objects initialized with a qualified expression.
13267 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13268 function result type, and use the finalization list associated with the
13269 function scope in that case (such an anonymous type should not be
13270 treated like an access parameter's type).
13271

13273 Gary Dismukes <dismukes@adacore.com>
13274 Javier Miranda <miranda@adacore.com>
13275
13276 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13277 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13278 required exception handler.
13279 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13280 properly the case of a function whose return type is a limited
13281 class-wide interface type. Modify the code of the accessibility
13282 check to handle class-wide interface objects. In this case we need to
13283 displace "this" to reference the primary dispatch table to get access
13284 to the TSD of the object (to evaluate its accessibility level).
13285 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13286 rather than a controlling result as one of the conditions for
13287 generating tests of the implicit BIP_Alloc_Form formal. The
13288 initialization assignment is also handled according to whether the
13289 result is tagged instead of controlling.
13290 In the case where the init assignment is inserted in the "then" part of
13291 the allocation conditional, rewrite the target to be a dereference of
13292 the implicit BIP_Object_Access formal.
13293 If the returned value is unconstrained and created on the secondary
13294 stack, mark the enclosing block and function so that the secondary
13295 stack is not reclaimed on return.
13296 Treat returns from functions with controlling results similarly to
13297 returns from functions with unconstrained result subtypes.
13298 If the object returned is unconstrained, and an allocator must be
13299 created for it, analyze the allocator once the block for the extended
13300 return is installed, to ensure that finalizable components
13301 of the expression use the proper finalization list. Guard the call to
13302 Move_Final_List with a check that there is something to finalize.
13303 (Make_Tag_Ctrl_Assignment): Use "old" handling
13304 of controlled type assignment for virtual machines, since new code uses
13305 unsupported features (such as direct access to bytes in memory).
13306
133072007-06-06 Gary Dismukes <dismukes@adacore.com>
13308 Ed Schonberg <schonberg@adacore.com>
13309
13310 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13311 accessibility actual, check for the case of an aliased object that has
13312 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13313 we fall into processing for the attribute rather than the name of the
13314 object.
13315 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13316 formal has its address taken in the body, create a temporary to capture
13317 value. If the return type is a limited interface, do not treat the
13318 return value as Controlled.
13319 (Is_In_Place_Function): If the return type is a limited interface,
13320 treat as returning in place. The actual returned object may not always
13321 be limited, but the caller has to assume that it is returned in place.
13322 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13323 context of an allocator, use the correct finalization chain (that is,
13324 the chain belonging to the access type, rather than the chain belonging
13325 to the current scope).
13326 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13327 result type rather than a controlling result as a precondition for
13328 adding an allocation form actual to a build-in-place call.
13329 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13330 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13331 primitive in the dispatch tables. This work is now done by Make_DT when
13332 the type is frozen.
13333 (Register_Predefined_DT_Entry): Removed.
13334 (Add_Return): If end label is not present, use sloc of last statement
13335 for generated return statement in procedure, for better gdb behavior
13336 on expanded code.
13337 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13338 object address nodes to ensure proper processing by routines like
13339 Insert_After*.
13340 (Expand_Call): Fix generation of validity check for parameter
13341 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13342 the allocation form parameter if the result subtype is constrained,
13343 except when the function has a controlling result.
13344 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13345 rather than Is_Controlled and Has_Controlled_Component, since we want to
13346 include class-wide result types in this treatment. Also test for a
13347 controlling result, since that also requires passing a finalization
13348 list.
13349 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13350 even when the result subtype is constrained, to handle calls involving
13351 controlling results.
13352 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13353 is now called even when the result subtype is constrained, to handle
13354 calls involving controlling results.
13355 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13356 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13357 now performs the test).
13358 (Make_Build_In_Place_Call_In_Object_Declaration):
13359 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13360 constrained, to handle calls involving controlling results.
13361 (Add_Return): Accomodate rewritten pattern from local raise to goto
13362 transformation, so that we still recognize an transfer statement
13363 and do the right thing here in that case.
13364 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13365 and end of subprogram code.
13366 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13367 support for primitives that are functions (without formals) with a
13368 controlling result.
13369 (Inherited_From_Formal): If the actual subtype has not generic parent
13370 type, it is not an actual for a formal derived type, and there is no
13371 operation to inherit from the formal.
13372

13374 Thomas Quinot <quinot@adacore.com>
13375
13376 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13377 inserted cleanup code appropriately for GDB use.
13378 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13379 exception handler for Deep_Adjust or Deep_Finalize.
13380 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13381 Raise_From_Controlled_Operation is available, use a call to that
13382 subprogram instead of a plain "raise Program_Error" node to raise
13383 Program_Error if an exception is propagated from an Adjust or Finalize
13384 operation.
13385 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13386 appears in the optional statement list of a triggering alternative, the

13408 for protected functions whose return type is an anonymous access to
13409 subprogram.

13417
13418 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13419 functionality when the backend is generating code.
13420 Otherwise any serious error
13421 reported by the backend calling the frontend routine Error_Msg
13422 changes the Compilation_Mode to Check_Semantics, disables the
13423 functionality of this routine and causes the generation of
13424 spureous additional errors.
13425
13426 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13427 debugging information now generated by the compiler for fat-pointer
13428 types.
13429 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13430 DWARF2/3.
13431 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.

13439 E.4(18) check to the returned value.
13440 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13441 stream attributes of the designated type of an RACW, as they are not
13442 dispatching primitive operations.

13461
13462 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13463 deallocation of class-wide interface objects.
13464 (Expand_Dispatching_Constructor_Call): Take into account that if the
13465 result of the dispatching constructor is an interface type, the
13466 function returns a class-wide interface type; otherwise the returned
13467 object would be actual. The frontend previously accepted returning
13468 interface types because Expand_Interface_Actuals silently performed
13469 the management of the returned type "as if" it were a class-wide
13470 interface type.
13471 (Expand_Dispatching_Constructor_Call): Replace call to
13472 Make_DT_Access_Action by direct call to Make_Function_Call.

13476
13477 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to

13481 to match the alignment.
13482 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for

13487 only if it is an access parameter.
13488 Increase size of C convention enumeration object
13489 (Freeze_Entity, array type case): Make sure Esize value is properly
13490 adjusted for the alignment if it is known.
13491 (Freeze_Entity, array type case): When checking bit packed arrays for
13492 the size being incorrect, check RM_Size, not Esize.
13493 (Freeze_Record_Type): Check for bad discriminated record convention
13494 (In_Exp_Body): Return true if the body is generated for a subprogram
13495 renaming, either an attribute renaming or a renaming as body.
13496 (Check_Itype): If the designated type of an anonymous access component
13497 is a non-protected subprogram type, indicate that it is frozen, to
13498 prevent out-of-scope freeze node at some subsequent call.
13499 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13500 only if the subprogram is neither imported nor exported, as well as the
13501 NCA descriptor class if the subprogram is exported.

13512 restriction
13513
13514 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma

13522 Pragma_CIL_Constructor): New names.
13523
13524 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13525 uses the equivalent aggregate of a type must be treated as an implicit
13526 initialization.
13527 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13528 has none of the other categories.
13529 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13530 to apply Import to an object renaming declaration.
13531
13532 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13533 from a C++ class should be declared as limited and that it will be
13534 considererd limited.
13535 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13536 should be declared as limited and that it will be considererd limited.

13559
13560 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13561 object of a limited type can be initialized with a call to a function
13562 that returns in place. If the limited type has unknown discriminants,
13563 and the underlying type is a constrained composite type, build an actual
13564 subtype from the function call, as is done for private types.
13565 (Side_Effect_Free): An expression that is the renaming of an object or
13566 whose prefix is the renaming of a object, is not side-effect free
13567 because it may be assigned through the renaming and its value must be
13568 captured in a temporary.
13569 (Has_Controlled_Coextensions): New routine.
13570 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13571 as is done for other limited types.

13645 return objects.
13646 Also reject attempt to rename function return object in Ada 83 mode.

13669 absolute value of Header.Block_Size when displaying the freed physical
13670 memory in traces.
13671 (Allocate): Compute Storage_Address using Integer_Address, not
13672 Storage_Offset, because the range of Storage_Offset may not be large

13682 (Is_Valid): Adjust comment to mention that a positive reply means that
13683 Header_Of may be used to retrieve the allocation header associated with
13684 the subprogram Storage address argument. Return False early if this
13685 address argument is misaligned.
13686
136872007-06-06 Vincent Celier <celier@adacore.com>
13688

13708 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13709 targets.
13710
137112007-06-06 Vincent Celier <celier@adacore.com>
13712

13726 they aren't modified.
13727 (Print_Back_Traces): allocate root arrays on the heap rather than stack.

13746 before processing the project files.
13747 (Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
13748 specified when symbol policy is Direct. Check that when there is a
13749 symbol file defined (either by default or with attribute
13750 Library_Symbol_File) it is not the same as the reference symbol file.
13751 (Check_Stand_Alone_Library): Recognize new symbol policy Direct.

13787 binding to obtain proper message.
13788 (Close_Selector): Use GNAT.Sockets.Thin.Signalling_Fds.Close.
13789 Replace various occurrences of Arry (Arry'First)'Address with the
13790 equivalent Arry'Address (GNAT always follows implementation advice from

13792 (Get_Host_By_Address, Get_Host_By_Name,
13793 Get_Service_By_Name, Get_Service_By_Port): Do not use GNAT.Task_Lock;
13794 instead, rely on platform-specific task safe netdb operations provided

13900 declaration, to ensure that the interface list is processed correctly.
13901 (Inline_Instance_Body): If enclosing scope is an instance body, remove
13902 its entities from visibiility as well.
13903 (Pre_Analyze_Actuals): if the actual is an allocator with constraints
13904 given with a named association, analyze the expression only, not the
13905 discriminant association itself.
13906 (Reset_Entity): If the analysis of a selected component is transformed
13907 into an expanded name in the prefix of a call with parameters, do not
13908 transform the original node into an expanded name, to prevent visibility

13910 (Check_Private_View): For an array type, check whether the index types
13911 may need exchanging.

14038 to Void.
14039 (Find_Type_Of_Object): In the case of an access definition, always set
14040 Is_Local_Anonymous_Access. We were previously not marking the anonymous

14059 improve the condition that avoids inheriting the components associated
14060 with secondary tags of the parent.
14061 (Build_Discriminanted_Subtype): Indicate to the backend that the
14062 size of record types associated with dispatch tables is known at

14082 of the type that specify the position of interface tags when the type
14083 inherits discriminated array components from the parent type.
14084 If a component is initialized with a box, check for the presence of a
14085 default expression in its declaration before using its default
14086 initialization procedure.
14087 (Resolve_Record_Aggregate): If a component is box-initialized, and the
14088 component type has a discriminants, create a partial aggregate for it
14089 by copying the discriminants of the component subtype.
14090 Reject attempt to initialize a discriminant with a box.
14091 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
14092 associated with dispatch tables is known at compile time.
14093 (Get_Value): If an association in a record aggregate has a box
14094 association, and the corresponding record component has a default
14095 expression, always copy the default expression, even when the
14096 association has a single choice, in order to create a proper
14097 association for the expanded aggregate.

14106 not null indicator.
14107
14108 * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If

14272 occurs on an allocator node. Add processing and cleanup for static
14273 coextensions.
14274 (Valid_Conversion): If the operand type is the limited view of a
14275 class-wide type, use the non-limited view is available to determine

14278 (Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
14279 (Resolve_Range): Diagnose properly an ambiguous range whose bounds are
14280 character literals.
14281 (Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
14282 Do_Division_Check flag explicitly.
14283 (Resolve_Actuals): If the actual is of a synchronized type, and the
14284 formal is of the corresponding record type, this is a call to a
14285 primitive operation of the type, that is declared outside of the type;
14286 the actual must be unchecked-converted to the type of the actual
14287 (Resolve_Call): Kill all current values for any subprogram call if
14288 flag Suppress_Value_Tracking_On_Call is set.

14321 both entities. This is required to statically build the dispatch table.
14322 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14323 of calling Set_All_DT_Position to re-evaluate the position of the
14324 entries in the dispatch table. Such reevaluation is not desired if

14355 return statement, call Type_Access_Level recursively on the enclosing
14356 function's result type to determine the level of the return object's
14357 type.
14358 (Build_Elaboration_Entity): Build name of elaboration entity from the
14359 scope chain of the entity, rather than the unit name of the file name.

15228 types.
15229 (Expr_Known_Valid): Validity checks do not apply to discriminants, but

15401 move tasks from the activation chain belonging to a return statement to
15402 the one passed in by the caller, and update the master to the one
15403 passed in by the caller.
15404 (Vulnerable_Complete_Master, Check_Unactivated_Tasks): Check the master
15405 of unactivated tasks, so we don't kill the ones that are being returned

15430
15431 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15432 for all access attributes, because overload resolution should work the
15433 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
15434 causes the error message for the ambiguous "X'Access = Y'Access" and
15435 "X'Unrestricted_Access = Y'Access" and so forth to match.
15436 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15437 now that anonymous access to protected operations have their own kind.

15446 already have been used in a self-referential anonymous access component.
15447 (Mentions_T): Recognize self-referential anonymous access components
15448 that use (a subtype of) the class-wide type of the enclosing type.
15449 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15450 Derived_Type for Prev formal on call to
15451 Check_Anonymous_Access_Components rather than Empty.
15452 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15453 a record extension in deciding whether to create a class-wide type,
15454 rather than just checking Tagged_Present.
15455 (Replace_Anonymous_Access_To_Protected_Subprogram): Procedure applies
15456 to stand-alone object declarations as well as component declarations.
15457 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15458 prevent accidental overwriting when enclosing package appears in
15459 a limited_with_clause.
15460 (Array_Type_Declaration): If the component type is an anonymous access,
15461 the associated_node for the itype is the type declaration itself.
15462 (Add_Interface_Tag_Components): Modified to support concurrent
15463 types with abstract interfaces.
15464 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
15465 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).
15466 (Build_Derived_Record_Type): Add call to Analyze_Interface_Declaration
15467 to complete the decoration of synchronized interface types. Add also

15470 with abstract interfaces.
15471 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15472 mark, rather than delaying the full resolution depending on context.

15478 Process_Full_View,Record_Type_Declaration): Split Is_Abstract flag into
15479 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
15480 called only when appropriate.

15482 to private type.
15483 (Analyze_Subtype_Declaration): For an access subtype declaration, create
15484 an itype reference for the anonymous designated subtype, to prevent
15485 scope anonmalies in gigi.

15501 (Compile): When compiling a predefined source, add -gnatpg
15502 as the second switch, after -c.
15503 (Compile_Sources): Allow compilation of Annex J renames without -a
15504 (Is_In_Object_Directory): Check if the ALI file is in the object
15505 even if there is no project extension.
15506 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15507 gnatbind if the ALI file effectively exists.
15508 (Initialize): Add the directory where gnatmake is invoked in front of
15509 the path if it is invoked from a bin directory, even without directory
15510 information, so that the correct GNAT tools will be used when spawned
15511 without directory information.
15512
15513 * makeusg.adb: Change switch -S to -eS
15514 Add lines for new switches -we, -wn and -ws

15533 * par.adb: Allow library units Calendar, Machine_Code,
15534 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15535 when -gnatg is not specified.
15536 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15537 there is no need to generate always a record_definition_node in case
15538 of synchronized interface types.
15539 (SIS_Entry_Active): Initialize global variable to False
15540 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15549 (Initialize): Add the directory where gprmake is invoked in front of the
15550 path, if it is invoked from a bin directory or with directory
15551 information, so that the correct GNAT tools will be used when invoked

15553 (Check_Compilation_Needed): Process correctly backslashes on Windows.
15554
15555 * vms_data.ads: Update switches/qualifiers

15559
15560 * exp_aggr.adb:
15561 If the array component is a discriminated record, the array aggregate
15562 is non-static even if the component is given by an aggregate with
15563 static components.
15564 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15565 (Convert_Aggr_In_Allocator): If the allocator is for an access
15566 discriminant and the type is controlled. do not place on a finalization
15567 list at this point. The proper list will be determined from the
15568 enclosing object.
15569 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15570 initialize record controller if needed, before the components, to ensure
15571 that they are properly finalized.
15572 (Build_Record_Aggr_Code): For the case of an array component that has a
15573 corresponding array aggregate in the record aggregate, perform sliding
15574 if required.

15580 * exp_ch13.adb (Expand_External_Tag_Definition): Replace call to the
15581 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
15582
15583 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
15584 accessibility on class-wide allocators if the allocator occurs at the
15585 same scope level as the allocator's type. The check is guaranteed to
15586 succeed in that case, even when the expression originates from a
15587 parameter of the containing subprogram.
15588 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15589 under No_Dispatching_Calls restriction. During the semantic analysis
15590 we already notified such violation.

15608 initialize most the TSD components by means of an aggregate.
15609 Modify the declaration of the object containing the TSD
15610 because we now expand code that has a higher level of abstraction.
15611 The TSD has a discriminant containing the Inheritance Depth Level,
15612 value that is used in the membership test but also to fix the size
15613 of the table of ancestors.
15614 (Expand_Interface_Conversion): Insert function body at the closest place
15615 to the conversion expression, to prevent access-before-elaboration
15616 errors in the backend.

15642 (Expand_Dispatching_Call): Replace generation of call to the run-time
15643 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by

15645 Address.
15646 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15647 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15648 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15649 Build_Set_Prim_Op_Address.
15650 (Get_Remotely_Callable): Subprogram removed.
15651 (Init_Predefined_Interface_Primitives): Replace generation of call to
15652 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15653 Prims.
15654
15655 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15656 First (Parameter_Associations ()) with the call to First_Actual that
15657 returns an actual parameter expression for both named and positional
15658 associations.
15659
15660 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15661 check violation of restriction No_Dispatching_Calls.

15666 First/Next_Component_Or_Discriminant
15667 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15668 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15669 specify Any_Limited_Interface, and this functionality is already
15670 provided by the function Has_Abstract_Interfaces.
15671 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15672 support concurrent types implementing interfaces.
15673 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15674 specify kind Any_Limited_Interface, and this functionality is already
15675 provided by the function Has_Abstract_Interfaces.
15676 (Remove_Side_Effects): replace Controlled_Type by
15677 CW_Or_Controlled_Type whenever the issue is related to
15678 using or not the secondary stack.
15679
15680 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15681 P_Interface_Type_Definition to fulfill the new interface (the formal
15682 Is_Synchronized is no longer required).

15720 a protected object, because they may be invoked through a callback.
15721 (Set_Privals): If the type of a private component is an anonymous access
15722 type, do not create a new itype for each protected body.
15723 If the body of a protected operation creates
15724 controlled types (including allocators for class-widetypes), the
15725 body of the corresponding protected subprogram must include a
15726 finalization list.
15727 (Build_Activation_Chain_Entity): Build the chain entity for extended
15728 return statements.
15729 (Type_Conformant_Parameters): Use common predicate Conforming_Types

15749 parameter that requires an extra constrained parameter, declare
15750 temporary for actual as a variable, not a constant.
15751 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15752 the unit being compiled is the one that contains the stub type.
15753 Change primitive operation name for the RACW associated with a RAS

15762 When expanding a package spec, this list correspond to the
15763 spec declarations.
15764 (Add_Receiving_Stubs_To_Declarations): Append the function
15765 registering the receiving stubs at the end of the 'Stmts' list.
15766 (RCI_Package_Locator): Pass the new Version generic formal when
15767 instantiating a RCI_Locator package.
15768 (Build_From_Any_Function): To compute the High bound for an
15769 unconstrained array actual, we add the Low bound with the length.
15770 Thus we must convert the low bound and the length to an appropriate
15771 type before doing the sum.
15772 (Build_Subprogram_Receiving_Stubs, PolyORB):
15773 * Retrieve the extra formals parameters at the
15774 end of the parameter stream.

15796 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15797 typecode from the Etype. Therefore we retrieve the correct typecode
15798 with a call to Get_Any_Type.
15799 (Copy_Specification): Do controlling formal type substitution based on
15800 Is_Controlling_Formal flag, instead of caller-provided object type.
15801 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15802 a RACW primitive operation, we might get a subprogram declaration for an
15803 ancestor of the RACW designated type (not for the designated type
15804 itself), in the case where this operation is inherited. In this case we
15805 have no easy means of determining the original tagged type for which
15806 the primitive was declared, so instead we now rely on
15807 Copy_Specification to use the Is_Controlling_Formal flag to determine
15808 which formals require type substitution.

16253 (Analyze_Formal_Object_Declaration): Add check for illegal default
16254 expressions for a formal in object of a limited type.
16255 (Instantiate_Object): Ditto.
16256 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16257 because they were defaulted in the formal package and no check applies
16258 to them.
16259 (Check_Formal_Package_Instance): Extend conformance check to other
16260 discrete types beyond Integer.
16261 (Process_Default): Copy directly the unmatched formal. A generic copy
16262 has already been performed in Analyze_Formal_Package.
16263 (Analyze_Associations): If a formal subprogram has no match, check for
16264 partial parametrization before looking for a default, to prevent
16265 spurious errors.
16266 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16267 not set the instantiation environment before analyzing the actuals.
16268 Fixes regression on 8515-003 with implementation of AI-133.
16269 Set_Instance_Env checks whether the generic unit is a predefined
16270 unit, in which case the instance must be analyzed with the latest Ada
16271 mode. This setting must take place after analysis of the actuals,
16272 because the actuals must be analyzed and frozen in the Ada mode extant
16273 outside of the current instantiation.

16275 parameters so that predefined units can be compiled in the proper Ada

16287
16288 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16289 prefix type is a discriminated subtype of the type of the formal.
16290 (Analyze_Allocator): Collect all coextensions regardless of the context.
16291 Whether they can be allocated statically is determined in exp_ch4.
16292 (Analyze_Selected_Component): If the prefix is a limited view and the
16293 non-limited view is available, use the non-limited one.
16294 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16295 therefore illegal), suggest a qualified expression rather than a type
16296 conversion, because a type conversion would be illegal in this context.
16297 (Anayze_Allocator): Trace recursively all nested allocators so that all
16298 coextensions are on the corresponding list for the root. Do no mark
16299 coextensions if the root allocator is within a declaration for a stack-
16300 allocated object, because the access discriminants will be allocated on
16301 the stack as well.
16302 (Analyze_Call): Remove restriction on calls to limited functions for the
16303 cases of generic actuals for formal objects, defaults for formal objects
16304 and defaults for record components.
16305 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16306 element list. Their expansion is delayed until the enclosing allocator
16307 is processed and its finalization list constructed.
16308 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16309 for an operation with the given name among the primitive operations of
16310 the corresponding record type.
16311 (Analyze_Selected_Component): If the prefix is a task type that
16312 implements an interface, and there is no entry with the given name,
16313 check whether there is another primitive operation (e.g. a function)
16314 with that name.
16315 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16316 properly the indexing of a function call written in prefix form, where
16317 the function returns an array type, and all parameters of the function
16318 except the first have defaults.
16319 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16320 the original operands, rather than relocating them, for efficiency and
16321 to work properly when an operand is overloaded.
16322 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16323 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16324 (Analyze_Selected_Component): If the prefix is a private extension, only
16325 scan the visible components, not those of the full view.
16326 (Try_Primitive_Operation): If the operation is a procedure, collect all
16327 possible interpretations, as for a function, because in the presence of
16328 classwide parameters several primitive operations of the type can match
16329 the given arguments.

16345 (Analyze_Package_Declaration): When the package declaration being
16346 analyzed does not require an explicit body, call Check_Completion.
16347 (May_Need_Implicit_Body): An implicit body is required when a package
16348 spec contains the declaration of a remote access-to-classwide type.
16349 (Analyze_Package_Body): If the package contains RACWs, append the
16350 pending subprogram bodies generated by exp_dist at the end of the body.
16351 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16352 Is_Abstract_Subprogram and Is_Abstract_Type.

16354 that must be preserved from full to partial view.

16359 Mark the full view of the designated type for the RACW associated with

16361 private declarations.
16362 Provite a placeholder nested package body along with the nested spec

16395 object O, use the access level of O.
16396 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16397 rather than local Same_Formal_Type, to check whether protected operation
16398 overrides an inherited one.
16399 (Same_Formal_Type): New predicate, used when matching signatures of
16400 overriding synchronized operations, to handle the case when a formal
16401 has a type that is a generic actual.
16402 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16403 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16404 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16405 syntactic ambiguities involving indexing of function calls that return

16413 with interface types.

16415 interface types.
16416 (Is_Parent): New subprogram that determines whether E1 is a parent
16417 of E2. For a concurrent type its parent is the first element of its
16418 list of interface types; for other types this function provides the
16419 same result than Is_Ancestor.
16420 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.

17293 compiling under full ABI compatibility mode we avoid the generation of

17468 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17469 are build-in-place function calls.
17470 (Replace_Self_Reference): New subsidiary of
17471 Make_OK_Assignment_Statement, to replace an access attribute that is a
17472 self-reference into an access to the appropriate component of the
17473 target object. Generalizes previous mechanism to handle self-references
17474 nested at any level.
17475 (Is_Self_Referential_Init): Remove, not needed.
17476 (Is_Self_Referential_Init): New predicate to simplify handling of self
17477 referential components in record aggregates.

17479 check for presence of entity before checking for self-reference.
17480 (Has_Default_Init_Comps): Return True if a component association is a

17482 default initialization.
17483 (Make_OK_Assignment_Statement): If the expression is of the form
17484 Typ'Acc, where Acc is an access attribute, the expression comes from a
17485 default initialized self-referential component.
17486 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17487 that has been derived from several abstract interfaces we must also
17488 initialize the tags of the secondary dispatch tables.

6f7f72f9
EB		 17496 (Expand_Access_To_Protected_Op): If the context indicates that an access
17497 to a local operation may be transfered outside of the object, create an
17498 access to the wrapper operation that must be used in an external call.
70198b9f
AC		 17499 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17500 target, pass the Valid attribute applied to a floating-point prefix on
17501 to the back end without expansion.
17502 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17503 the allocated storage when it is specified by a per-object expression.

17507 (Expand_Attribute_Reference): Handle expansion of the new Priority
17508 attribute
17509 (Find_Fat_Info): Handle case of universal real
17510 (Expand_Access_To_Protected_Op): Fix use of access to protected
17511 subprogram from inside the body of a protected entry.
17512 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17513 'Access and 'Unrestricted_Access, to transform the attribute reference
17514 into a fat pointer.
17515 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17516 subcomponent's enclosing variable is aliased with a constrained subtype.
17517 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17518 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17519 an aliased prefix must be known to be constrained in order to use True
17520 for the attribute value, and now it's possible for some aliased views
17521 to be unconstrained.

6f7f72f9 17534 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
70198b9f
AC		 17535 register in the final list objects containing class-wide interfaces;
17536 otherwise we incorrectly register the tag of the interface in the final
17537 list.
6f7f72f9
EB		 17538 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17539 generate the wrapper if the parent primitive is abstract. This is
17540 required to report the correct error message.
17541 (Expand_N_Subtype_Indication): Do validity checks on range
70198b9f
AC		 17542 (Clean_Task_Names): If an initialization procedure includes a call to
17543 initialize a task (sub)component, indicate that the procedure will use
17544 the secondary stack.
17545 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17546 compatibility for interfacing with CPP by default.
17547 (Expand_N_Object_Declaration): Only build an Adjust call when the
17548 object's type is a nonlimited controlled type.
17549 * exp_ch3.adb: Add with and use of Exp_Ch6.
17550 (Expand_N_Object_Declaration): Check for object initialization that is a
17551 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17552 Object_Declaration to the call.
17553 (Freeze_Type): When the designated type of an RACW was not frozen at the
17554 point where the RACW was declared, validate the primitive operations
17555 with respect to E.2.2(14) when it finally is frozen.
17556 (Build_Initialization_Call,Expand_Record_Controller): Rename
17557 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17558 return-by-reference has no meaning in Ada 2005.
17559 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17560 to register tag of the immediate ancestor interfaces in the
17561 run-time structure.
17562 (Init_Secondary_Tags): Moved to the specification to allow the
17563 initialization of extension aggregates with abstract interfaces.
17564 (Build_Master_Renaming): Make public, for use by function declarations
17565 whose return type is an anonymous access type.
17566 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17567 Insert_List_Before_And_Analyze after the generation of the specs
17568 associated with null procedures.
17569 (Expand_Tagged_Root): Update documentation in its specification.
17570 (Init_Secondary_Tags): Update documentation.
17571 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17572 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17573 then generate code to inherit the contents of the dispatch table
17574 directly from the ancestor.
17575 (Expand_Record_Controller): Insert controller component after tags of
17576 implemented interfaces.
17577 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17578 create null procedure overridings when null procedures are inherited
17579 from interfaces.
17580 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17581 declarations for overriding null primitives inherited from interfaces.
17582 (Is_Null_Interface_Procedure): New function in
17583 Make_Null_Procedure_Specs.
17584 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17585 immediate ancestor of a tagged type is an abstract interface type we
17586 must generate the specification of the predefined primitives associated
17587 with controlled types (because the dispatch table of the ancestor is
17588 null and hence these entries cannot be inherited). This is required to
17589 elaborate well the dispatch table.

AC		 17600 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17601 (Expand_N_Allocator): For "new T", if the object is constrained by
17602 discriminant defaults, allocate the right amount of memory, rather than
17603 the maximum for type T.
17604 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17605 when the allocator is initialized by a build-in-place call, since the
17606 allocator is already rewritten as a reference to the function result,
17607 and this prevents an unwanted duplication of the function call.
17608 Add with and use of Exp_Ch6.
17609 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17610 is a call to build-in-place function and apply
17611 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17612 untagged designated types).
17613 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17614 optimization if source or target is biased.
17615 (Expand_N_Allocator): Add comments for case of an allocator within a
17616 function that returns an anonymous access type designating tasks.

70198b9f
AC		 17628 (Expand_N_Assignment_Statement): Call
17629 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17630 build-in-place function call. Currently, this can happen only for
17631 assignments that come from aggregates.
17632 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17633 in order to alleviate the upward compatibility introduced by AI-318.
17634 (Expand_N_Extended_Return_Statement): Add support for handling the
17635 return object as a build-in-place result.
17636 (Expand_Non_Function_Return): Implement simple return statements nested
17637 within an extended return.
17638 (Enable_New_Return_Processing): Turn on the new processing of return
17639 statements.
17640 (Expand_Non_Function_Return): For a return within an extended return,
17641 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17642 (Expand_N_Extended_Return_Statement): Implement AI-318
17643 (Expand_Simple_Function_Return): Ditto.
17644 (Expand_N_If_Statement): Handle new -gnatwt warning
17645 (Expand_N_Case_Statement): Handle new -gnatwt warning
17646 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17647 a protected object.
17648 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17649 validity checking of assignments to elementary record components.
17650 (Expand_N_Return_Statement): return Class Wide types on the secondary
17651 stack independantly of their controlled status since with HIE runtimes,
17652 class wide types are not potentially controlled anymore.
17653
17654 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17655 node kind.
17656
17657 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17658 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17659 it expects a block, procedure, or task. The return statement will get
17660 turned into a block, and Expand_Cleanup_Actions will happen then.

17667 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17668 capability.
17669 (Expand_Inlined_Call): Tagged types are by-reference types, and
17670 therefore should be replaced by a renaming declaration in the expanded
17671 body, as is done for limited types.
17672 (Expand_Call): If this is a call to a function with dispatching access
17673 result, propagate tag from context.
17674 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17675 CPP by default.
17676 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17677 build-in-place when the right-hand side of an assignment is a
17678 build-in-place function call.
17679 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17680 of the explicit dereference of the allocator to the result subtype of
17681 the build-in-place function. This is needed to satisfy type checking
17682 in cases where the caller's return object is created by an allocator for
17683 a class-wide access type and the type named in the allocator is a
17684 specific type.
17685 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17686 conversion of the reference to the declared object to the result subtype
17687 of the build-in-place function. This is needed to satisfy type checking
17688 in cases where the declared object has a class-wide type. Also, in the
17689 class-wide case, change the type of the object entity to the specific
17690 result subtype of the function, to avoid passing a class-wide object
17691 without explicit initialization to the back end.
17692 (Register_Interface_DT_Entry): Moved outside the body of
17693 Freeze_Subprogram because this routine is now public; it is called from
17694 Check_Dispatching_Overriding to handle late overriding of abstract
17695 interface primitives.
17696 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17697 adding an implicit access actual on a call to a build-in-place function.
17698 (Expand_Actuals): Test for an actual parameter that is a call to a
17699 build-in-place function and apply
17700 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17701 (Is_Build_In_Place_Function): New function to determine whether an
17702 entity is a function whose calls should be handled as build-in-place.
17703 (Is_Build_In_Place_Function_Call): New function to determine whether an
17704 expression is a function call that should handled as build-in-place.
17705 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17706 calls to build-in-place functions as the initialization of an allocator.
17707 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17708 handling calls to build-in-place functions in contexts that do not
17709 involve init of a separate object (for example, actuals of subprogram
17710 calls).
17711 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17712 handling calls to build-in-place functions as the initialization of an
17713 object declaration.
17714 (Detect_Infinite_Recursion): Add explicit parameter Process to
17715 instantiation of Traverse_Body to avoid unreferenced warning.
17716 (Check_Overriding_Inherited_Interfaces): Removed.
17717 (Register_Interface_DT_Entry): Code cleanup.
17718 (Register_Predefined_DT_Entry): Code cleanup.
17719 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17720 inlined statements if within a transient scope.
17721 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17722 formal parameters with occurrences of actuals in inlined body, establish
17723 visibility on the proper view of the actual's subtype for the body's
17724 context.
17725 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17726 compatibility mode and we have an imported CPP subprogram because
17727 for now we assume that imported CPP primitives correspond with
17728 objects whose constructor is in the CPP side (and therefore we
17729 don't need to generate code to register them in the dispatch table).
17730 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17731 aligned selected component.
17732 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17733 the actual of an in-mode parameter is a type conversion.
17734 (Expand_Actuals): If the call does not come from source and the actual
17735 is potentially misaligned, let gigi handle it rather than rejecting the
17736 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17737 Class Wide types as returning by reference independantly of their
17738 controlled status since with HIE runtimes class wide types are not
17739 potentially controlled anymore.

17771 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17772 type for an RACW type.
17773 (Add_RACW_Features): When processing an RACW declaration for which the
17774 designated type is already frozen, enforce E.2.2(14) rules immediately.
17775 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17776 special reordering of controlling formals.
17777
17778 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17779 associated stub type for an RACW type.
17780
177812006-10-31 Ed Schonberg <schonberg@adacore.com>
17782
17783 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17784 fixed-point operations in an integer context, i.e. as operands of a
17785 conversion to an integer type, indicate that result must be rounded.
17786
177872006-10-31 Robert Dewar <dewar@adacore.com>
17788
17789 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17790 cases, pass the encoding method, since it is now required by the run
17791 time.
17792
17793 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17794 assumption that Str'First = 1.
17795 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17796 it on to the Value_Wide_Wide_Character call.
17797 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17798 properly handles a string of the form quote-encoded_wide_char-quote.
17799
17800 * s-wchcnv.adb: Minor reformatting
17801
178022006-10-31 Javier Miranda <miranda@adacore.com>
6f7f72f9 17803
70198b9f
AC		 17804 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17805 run-time membership test to ensure that the constructed object
17806 implements the target abstract interface.
17807
178082006-10-31 Robert Dewar <dewar@adacore.com>
17809
17810 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17811 Machine_Attribute pragma internally to implement the user pragma.
17812 Add processing for pragma Interface so that it is now completely
17813 equivalent to pragma Import.
17814
17815 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17816 so that it can be applied to all entities, including record components
17817 and enumeration literals.
17818 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17819 priority ranges are correct, verify compatibility against task
17820 dispatching and locking policies, and if everything is correct an entry
17821 is added to the table containing priority specific dispatching entries
17822 for this compilation unit.
17823 (Delay_Config_Pragma_Analyze): Delay processing
17824 Priority_Specific_Dispatching pragmas because when processing the
17825 pragma we need to access run-time data, such as the range of
17826 System.Any_Priority.
17827 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17828 Allow pragma Unreferenced as a context item
17829 Add pragma Preelaborable_Initialization
17830 (Analyze_Pragma, case Interface): Interface is extended so that it is
17831 now syntactically and semantically equivalent to Import.
17832 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17833 insertion characters.
17834 Add handling for Pragma_Wide_Character_Encoding
17835 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17836 never supercedes a real restriction, and that a real restriction
17837 always supercedes a warning.
17838 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
17839 appropriate form.
17840
178412006-10-31 Bob Duff <duff@adacore.com>
17842 Ed Schonberg <schonberg@adacore.com>
17843 Robert Dewar <dewar@adacore.com>
17844
17845 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17846 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17847 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17848 in Ada 2005.
17849 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17850 type of the function containing a return statement, because the
17851 Return_Type field was removed. We now use the Return_Applies_To field.
17852
6f7f72f9 17853 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
70198b9f
AC		 17854 (Build_Task_Image_Decl): If procedure is not called from an
17855 initialization procedure, indicate that function that builds task name
17856 uses the sec. stack. Otherwise the enclosing initialization procedure
17857 will carry the indication.
17858 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17859 N_Object_Declaration instead.
17860 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17861 conditional dead code killed, and change implementation accordingly.
17862 (Insert_Actions): Add N_Return_Object_Declaration case.
17863 Correct comment to mention N_Extension_Aggregate node.
17864 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17865 attempts to save information for global variables which cannot be
17866 safely tracked.
17867 (Get_Current_Value_Condition): Handle conditions the other way round
17868 (constant on left). Also handle right operand of AND and AND THEN
17869 (Set_Current_Value_Condition): Corresponding changes
17870 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17871 (Get_Current_Value_Condition): Handle simple boolean operands
17872 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17873 (Get_Current_Value_Condition): If the variable reference is within an
17874 if-statement, does not appear in the list of then_statments, and does
17875 not come from source, treat it as being at unknown location.
17876 (Get_Current_Value_Condition): Enhance to allow while statements to be
17877 processed as well as if statements.
17878 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17879 come from source.
17880 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17881 of loop. This is safe now that we fixed Kill_Current_Values.
17882 (OK_To_Do_Constant_Replacement): Check whether current scope is
17883 Standard, before examining outer scopes.
17884
178852006-10-31 Vincent Celier <celier@adacore.com>
17886
17887 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17888 When True, apply VMS treatment to children of packages A, G, I and S.
17889 For F320-016
17890
17891 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17892
178932006-10-31 Robert Dewar <dewar@adacore.com>
17894 Ed Schonberg <schonberg@adacore.com>
17895
17896 * freeze.adb: Add handling of Last_Assignment field
17897 (Warn_Overlay): Supply missing continuation marks in error msgs
17898 (Freeze_Entity): Add check for Preelaborable_Initialization
17899
17900 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17901
17902 * g-expect.adb: Add Warnings (Off) to prevent new warning
17903
17904 * lib-xref.adb: Add handling of Last_Assignment field
17905 (Generate_Reference): Centralize handling of pragma Obsolescent here
17906 (Generate_Reference): Accept an implicit reference generated for a
17907 default in an instance.
17908 (Generate_Reference): Accept a reference for a node that is not in the
17909 main unit, if it is the generic body corresponding to an subprogram
17910 instantiation.
17911
17912 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17913
6f7f72f9 17914 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
70198b9f
AC		 17915 -gnatwq/Q.
17916 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17917 exception handler.
17918 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17919 use clauses, to avoid messages on packages used to qualify, and also
17920 to avoid messages from obsolescent units.
17921 (Warn_On_Useless_Assignments): Don't generate messages for imported
17922 and exported variables.
17923 (Warn_On_Useless_Assignments): New procedure
17924 (Output_Obsolescent_Entity_Warnings): New procedure
17925 (Check_Code_Statement): New procedure
17926
6f7f72f9 17927 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
70198b9f
AC		 17928 Change name Is_Ada_2005 to Is_Ada_2005_Only
17929 (Last_Assignment): New field for useless assignment warning
17930
179312006-10-31 Olivier Hainque <hainque@adacore.com>
17932
17933 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17934 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17935
179362006-10-31 Bob Duff <duff@adacore.com>
17937 Robert Dewar <dewar@adacore.com>
17938 Ed Schonberg <schonberg@adacore.com>
17939
17940 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17941 Ada 95 mode, because it violates the new rules for AI-318.
17942
17943 * g-awk.ads: Use overloaded subprograms in every case where we used to
17944 have a default of Current_Session. This makes the code closer to be
17945 correct for both Ada 95 and 2005.
17946
17947 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17948 code, relying on the fact that the compiler generates a warning
17949 instead of an error in -gnatg mode.
17950
17951 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17952 E_Return_Statement entity kind.
17953 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17954
17955 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17956 report an error if the reserved word abstract has been previously found.
17957 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
6f7f72f9
EB		 17958
17959 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
70198b9f
AC		 17960 parenthesized range attribute usage
17961 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17962
17963 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17964 in the syntax for extended_return_statement. This is not in the latest
17965 RM, but the ARG is expected to issue an AI allowing this.
17966 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17967 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17968 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17969 P_Return_Statement): Parse the new syntax for extended_return_statement.
17970
17971 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17972 Output_End_Missing): Add error-recovery code for the new
17973 extended_return_statement syntax; that is, the new E_Return entry on
17974 the scope stack.
17975
17976 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17977 limited to nonlimited, because otherwise we violate the new Ada 2005
17978 rules about returning limited types in function Create_AST_Handler in
17979 s-asthan.adb.
17980
17981 * sem.adb (Analyze): Add cases for new node kinds
17982 N_Extended_Return_Statement and N_Return_Object_Declaration.
17983
17984 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17985 type is in the same category as type of context before applying check,
17986 to prevent anomalies in instantiations.
17987 (Resolve_Aggregate): Remove test for limited components in aggregates.
17988 It's unnecessary in Ada 95, because if it has limited components, then
17989 it must be limited. It's wrong in Ada 2005, because limited aggregates
17990 are now allowed.
17991 (Resolve_Record_Aggregate): Move check for limited types later, because
17992 OK_For_Limited_Init requires its argument to have been resolved.
17993 (Get_Value): When copying the component default expression for a
17994 defaulted association in an aggregate, use the sloc of the aggregate
17995 and not that of the original expression, to prevent spurious
17996 elaboration errors, when the expression includes function calls.
17997 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17998 were missing. We also didn't handle qualified expressions. Now also
17999 allow function calls. Use new common routine OK_For_Limited_Init.
18000 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18001 with space can upper case letter).
18002
6f7f72f9 18003 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
70198b9f 18004 Has_Static_Discriminants flag
6f7f72f9
EB		 18005 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18006 type with discriminants.
18007 (Process_Range_Expr_In_Decl): Do validity checks on range
70198b9f
AC		 18008 (Build_Discriminant_Constraints): Use updated form of
18009 Denotes_Discriminant.
18010 (Process_Subtype): If the subtype is a private subtype whose full view
18011 is a concurrent subtype, introduce an itype reference to prevent scope
18012 anomalies in gigi.
18013 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18014 Record_Type_Declaration): The functionality of the subprograms
18015 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18016 is now performed by a single routine.
18017 (Build_Derived_Record_Type): If the type definition includes an explicit
18018 indication of limitedness, then the type must be marked as limited here
18019 to ensure that any access discriminants will not be treated as having
18020 a local anonymous access type.
18021 (Check_Abstract_Overriding): Issue a detailed error message when an
18022 abstract subprogram was not overridden due to incorrect mode of its
18023 first parameter.
18024 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18025 synchronized private extension declarations. Verify that the ancestor is
18026 a limited or synchronized interface or in the generic case, the ancestor
18027 is a tagged limited type or synchronized interface and all progenitors
18028 are either limited or synchronized interfaces.
18029 Derived_Type_Declaration): Check for presence of private extension when
18030 dealing with synchronized formal derived types.
18031 Process_Full_View): Enchance the check done on the usage of "limited" by
18032 testing whether the private view is synchronized.
18033 Verify that a synchronized private view is completed by a protected or
18034 task type.
18035 (OK_For_Limited_Init_In_05): New function.
18036 (Analyze_Object_Declaration): Move check for limited types later,
18037 because OK_For_Limited_Init requires its argument to have been resolved.
18038 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18039 in order to alleviate the upward compatibility introduced by AI-318.
18040 (Constrain_Corresponding_Record): If the constraint is for a component
18041 subtype, mark the itype as frozen, to avoid out-of-scope references to
18042 discriminants in the back-end.
18043 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18044 this subprogram against wrong sources.
18045 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18046 discriminant of limited type completed with a protected type, when the
18047 discriminant is used to constrain a private component of the type, and
18048 expansion is disabled.
18049 (Find_Type_Of_Object): Do not treat a return subtype that is an
18050 anonymous subtype as a local_anonymous_type, because its accessibility
18051 level is the return type of the enclosing function.
18052 (Check_Initialization): In -gnatg mode, turn the error "cannot
18053 initialize entities of limited type" into a warning.
18054 (OK_For_Limited_Init): Return true for generated nodes, since it
18055 sometimes violates the legality rules.
18056 (Make_Incomplete_Declaration): If the type for which an incomplete
18057 declaration is created happens to be the currently visible entity,
18058 preserve the homonym chain when removing it from visibility.
18059 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18060 inherited subprograms.
18061 (Access_Definition): If this is an access to function that is the return
18062 type of an access_to_function definition, context is a type declaration
18063 and the scope of the anonymous type is the current one.
18064 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18065 incomplete subtype to the set of private dependents of the original
18066 incomplete type.
18067 (Constrain_Discriminated_Type): Emit an error message whenever an
18068 incomplete subtype is being constrained.
18069 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18070 corresponding subtype of the full view of the original incomplete type.
18071 (Check_Incomplete): Properly detect invalid usage of incomplete types
18072 and subtypes.
18073

18085 Robert Dewar <dewar@adacore.com>
18086
18087 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18088 handling executable extension manually and duplicating code.
18089
18090 * make.adb: Implement new -S switch
18091 (Gnatmake): Use new function Osint.Executable_Name instead
18092 of handling executable extension manually.
18093
18094 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18095 is specified, the executable name ends with this suffix.
18096 Take advantage of Osint.Executable_Name instead of duplicating code.
18097
18098 * switch-m.adb: Recognize new gnatmake -S switch
18099
18100 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New

18106
181072006-10-31 Vincent Celier <celier@adacore.com>
18108
18109 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18110 call it with -static-libgcc, as there are some platforms, such as
18111 Darwin, where one of these two switches is compulsory to link.
18112

6f7f72f9 18114
70198b9f
AC		 18115 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18116 instead of ADA_PROJECT_PATH, for the project path.
18117 (Gnatls): When displaying the project path directories, use host dir
18118 specs.
18119
18120 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18121 names in the project path, as absolute paths may correspond to
18122 multi-valued VMS logical names.
18123
181242006-10-31 Vincent Celier <celier@adacore.com>
18125
18126 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18127 absolute path name.
18128 (Locate_Regular_File): Ditto
18129 (Change_Dir): Remove, no longer used
18130 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18131 on Windows. Get it calling Get_Current_Dir.
18132 (OpenVMS): Remove imported boolean, no longer needed.
18133 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18134 (Pid_To_Integer): New function to convert a Process_Id to Integer
18135
181362006-10-31 Thomas Quinot <quinot@adacore.com>
18137
18138 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18139 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18140 to No_Socket.
18141 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18142 W_Sig_Socket.
18143
181442006-10-31 Robert Dewar <dewar@adacore.com>

18154
6f7f72f9
EB		 18155 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18156 variant records
18157 (Layout_Variant_Record): Retrieve the discriminants from the entity
70198b9f
AC		 18158 rather than from the type definition, because in the case of a full
18159 type for a private type we need to take the discriminants from the
18160 partial view.
6f7f72f9
EB		 18161 (Layout_Component_List): When applying the Max operator to variants with
18162 a nonstatic size, check whether either operand is static and scale that
18163 operand from bits to storage units before applying Max.
70198b9f
AC		 18164 (Layout_Type): In VMS, if a C-convention access type has no explicit
18165 size clause (and does not inherit one in the case of a derived type),
18166 then the size is reset to 32 from 64.
18167
181682006-10-31 Vincent Celier <celier@adacore.com>
18169
18170 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18171 its file has already been loaded, according to the unit being loaded,

18177
18178 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18179 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18180 possible.
18181 (a-except.o): Pass it to the compiler.
18182 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18183 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18184 a-calend-mingw.adb version.
18185
6f7f72f9 18186 * Makefile.rtl: Added s-dsaser.
70198b9f

18188 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18189 Ada.Dispatching.Round_Robin.
18190 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18191
18192 * Make-lang.in: Remove all references to gt-ada-decl.h.
18193 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18194 sources.
18195 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18196 Update dependencies.
18197
18198 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18199
182002006-10-31 Vincent Celier <celier@adacore.com>
18201
18202 * mlib-utl.adb (Initialized): Remove, no longer used
18203 (Initialize): Remove, no longer used
18204 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18205 if there is one, the archive indexer. Fail if the archive builder cannot
18206 be found.
18207 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18208 be found.
18209
182102006-10-31 Ed Schonberg <schonberg@adacore.com>
18211
18212 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18213 Process_Body_Clauses): If the context of a body includes a use clause
18214 for P.Q then a with_clause for P in the same body is not redundant,
18215 even if the spec also has a with_clause on P.
18216 Add missing continuation mark to error msg
18217 (Build_Limited_Views): A limited view of a type is tagged if its
18218 declaration includes a record extension.
18219 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18220 node, even if the subunit has errors. This avoids malfunction by
18221 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18222 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18223 generation of obsolescent messages for with statements (cannot do
18224 this too early, or we cannot implement avoiding the messages in the
18225 case of obsolescent units withing obsolescent units).
18226 (Install_Siblings): If the with_clause is on a remote descendant of
18227 an ancestor of the current compilation unit, find whether there is
18228 a sibling child unit that is immediately visible.
18229 (Remove_Private_With_Clauses): New procedure, invoked after completing
18230 the analysis of the private part of a nested package, to remove from
18231 visibility the private with_clauses of the enclosing package
18232 declaration.
18233 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18234 now centralized in Generate_Reference.
18235 (Install_Limited_Context_Clauses): Remove superfluous error
18236 message associated with unlimited view visible through use
18237 and renamings. In addition, at the point in which the error
18238 is reported, we add the backslash to the text of the error
18239 to ensure that it is reported as a single error message.
18240 Use new // insertion for some continuation messages
18241 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18242 to create implicit with_clause for parent unit mentioned in original
18243 limited_with_clause.
18244 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18245 unit is a child unit. For ASIS queries.
18246 (Analyze_Subunit): If the subunit appears within a child unit, make all
18247 ancestor child units directly visible again.

18257 (P_Formal_Type_Definition, P_Formal_Derived_Type_Definition): Add
18258 support for synchronized derived type definitions.
18259 Add the new actual Abstract_Present to every call to
18260 P_Interface_Type_Definition.
18261 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18262 a formal object declaration with an access definition or a subtype mark
18263 with a null exclusion.
18264 (P_Generic_Association): Handle association with box, and others_choice
18265 with box, to support Ada 2005 partially parametrized formal packages.
18266

70198b9f
AC		 18270 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18271 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18272 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18273 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18274 private extensions.
18275 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18276 to P_Interface_Type_Definition.
18277 (P_Interface_Type_Definition): Addition of one formal to report an error
18278 if the reserved word abstract has been previously found.
18279 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18280 object renaming declaration with an access definition or subtype mark
18281 with a possible null exclusion.
18282
18283 * par-ch9.adb: Minor error msg fix
18284
18285 * par-load.adb: Add missing continuation mark to error msg
18286
18287 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation
18288
182892006-10-31 Vincent Celier <celier@adacore.com>
18290
18291 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
18292 unknown attribute in unknown package or in package that does not need
18293 to be checked.
18294 (Parse_Package_Declaration): Do not issue warning for unknown package in
18295 quiet output.
18296
182972006-10-31 Vincent Celier <celier@adacore.com>
18298
18299 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18300 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18301 Packages_To_Check.
18302
183032006-10-31 Vincent Celier <celier@adacore.com>
18304
18305 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18306 on VMS, change "__" to '.' before checking the name.
18307 (Record_Ada_Source): Always add the source file name in the list of
18308 of sources, even if it is not the first time, as it is for another
18309 source index.
18310 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18311 dot, instead of replacing only the first '_'.
18312
18313 * prj-part.adb (Parse): Convert project file path to canonical form
18314
18315 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18316 extended, the project id of the project extending it is recorded in its
18317 data, even when it has already been processed as an imported project.
18318
183192006-10-31 Robert Dewar <dewar@adacore.com>
18320
18321 * repinfo.adb (List_Entities): Don't list entities from renaming
18322 declarations.

18325 Robert Dewar <dewar@adacore.com>
18326
18327 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18328 only a restriction warning is active for the given restriction. This is
18329 desirable because we do not want to modify code in the case where only
18330 a warning is set.
18331 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18332 causes overriding of real restrictions.
18333 Take advantage of new No_Restrictions constant.
18334
18335 * raise.h: (__gnat_set_globals): Change profile.
18336

18343 Move all the entities in obsolete package System.PolyORB_Interface to
18344 System.Partition_Interface.
70198b9f
AC		 18345 (RE_Storage_Size): New function in System.Tasking.
18346 (RE_Get_Ceiling): New entity.
18347 (RE_Set_Ceiling): New entity.
18348 (RO_PE_Get_Ceiling): New entity.
18349 (RO_RE_Set_Ceiling): New entity.
18350 (Inherit_CPP_DT): New entity
18351
183522006-10-31 Robert Dewar <dewar@adacore.com>
18353
18354 * scng.adb (Scan, case of numeric literal): Better msg for identifier
18355 starting with a digit.

18361
18362 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18363 properly an attempt to apply Unchecked_Access to a protected operation.
18364 (OK_Self_Reference): New subprogram to check the legality of an access
18365 attribute whose prefix is the type of an enclosing aggregate.
18366 Generalizes previous mechanism to handle attribute references nested
18367 arbitrarily deep within the aggregate.
18368 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18369 can appear in an aggregate if this is a default-initialized aggregate
18370 for a self-referential type.
18371 (Resolve_Attribute, case Access): Ditto.
18372 Add support for new implementation defined attribute Stub_Type.
18373 (Eval_Attribute, case Attribute_Stub_Type): New case.
18374 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18375 (Stream_Attribute_Available): Implement using new subprogram from
18376 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18377 Has_Specified_Stream_Attribute flag.
18378 Disallow Storage_Size and Storage_Pool for access to subprogram
18379 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18380 access types of return subtypes in extended return statements. Remove
18381 accessibility checks on anonymous access types when Unchecked_Access is
18382 used.
18383 (Analyze_Attribute): Add support for the use of 'Class to convert
18384 a class-wide interface to a tagged type.
18385 Add support for the attribute Priority.
18386 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18387 whether the designated type is discriminated with a constrained partial
18388 view and require static matching in that case.
18389 Add local variable Des_Btyp. The Designated_Type
18390 of an access to incomplete subtype is either its non-limited view if
18391 coming from a limited with or its etype if regular incomplete subtype.
18392
18393 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18394 Fix predicate to identify and allow cases of (expander-generated)
18395 references to tag of designated object of a RACW.
18396 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18397 non-static, and therefore cannot appear as a primary in a preelaborable
18398 package.
18399 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18400 Has_Read_Write_Attributes.
18401 (Has_Read_Write_Attributes): Reimplement in termes of
18402 Has_Stream_Attribute_Definition.
18403 (Missing_Read_Write_Attributes): When checking component types in a
18404 record, unconditionally call Missing_Read_Write_Attributes recursively
18405 (remove guard checking for Is_Record_Type / Is_Access_Type).
18406
184072006-10-31 Robert Dewar <dewar@adacore.com>
18408
18409 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18410 useless assignments here and conditionalize it on absence of exception
18411 handlers.
18412 (Analyze_Exception_Handlers): Small code reorganization of error
18413 detection code, for new handling of formal packages.
18414

6f7f72f9
EB		 18417
18418 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
70198b9f
AC		 18419 that has been constant-folded, preserve information of original tree,
18420 for ASIS uses.
18421 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18422 generated private extension declaration if the formal derived type is
18423 synchronized. Carry synchronized present over to the generated private
18424 extension.
18425 (Validate_Derived_Type_Instance): Ensure that the actual of a
18426 synchronized formal derived type is a synchronized tagged type.
18427 (Instantiate_Formal_Package): When creating the instantiation used to
18428 validate the actual package of a formal declared without a box, check
18429 whether the formal itself depends on a prior actual.
18430 (Instantiate_Formal_Subprogram): Create new entities for the defining
18431 identifiers of the formals in the renaming declaration, for ASIS use.
18432 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18433 a renaming declaration or a subtype declaration for an actual in an
18434 instance, capture location information of declaration in generic, for
18435 ASIS use.
18436 (Instantiate_Formal_Package): Add comments on needed additional tests.
18437 AI-317 (partial parametrization) is fully implemented.
18438 (Validate_Private_Type_Instance): Add check for actual which
18439 must have preelaborable initialization
18440 Use new // insertion for some continuation messages
18441 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18442 Default_Expression. Add type retrieval when the declaration has an
18443 access definition. Update premature usage of incomplete type check.
18444 (Check_Access_Definition): New subsidiary routine. Check whether the
18445 current compilation version is Ada 05 and the supplied node has an
18446 access definition.
18447 (Instantiate object): Alphabetize local variables. Handle the creation
18448 of new renaming declarations with respect to the kind of definition
18449 used - either an access definition or a subtype mark. Guard against
18450 unnecessary error message in the context of anonymous access types after
18451 they have been resolved. Add check for required null exclusion in a
18452 formal object declaration.
18453 (Switch_View): A private subtype of a non-private type needs to be
18454 switched (the base type can have been switched without its private
18455 dependents because of the last branch of Check_Private_View.
18456 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18457 value from BT.
18458 (Instantiate_Type): Emit an error message whenever a class-wide type of
18459 a tagged incomplete type is used as a generic actual.
18460 (Find_Actual_Type): Extend routine to handle a component type in a child
18461 unit that is imported from a formal package in a parent.
18462 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18463 agree on constrainedness, rather than checking against ultimate ancestor
18464 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18465 generic body, for navigation purposes.
18466
184672006-10-31 Robert Dewar <dewar@adacore.com>
18468 Thomas Quinot <quinot@adacore.com>
18469
18470 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18471 type.
18472 (New_Stream_Subprogram): When processing an attribute definition clause
18473 for a stream-oriented subprogram, record an entity node occurring at
18474 the point of clause to use for checking the visibility of the clause,
18475 as defined by 8.3(23) as amended by AI-195.
18476 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18477 New_Stream_Function and New_Stream_Procedure.
18478 (New_Stream_Function, New_Stream_Procedure): Removed.
18479 (Analyze_Attribute_Definition_Clause, case Address): Check new
18480 Alignment_Check check

18484 Robert Dewar <dewar@adacore.com>
18485
18486 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18487 generate the same errors compiling under -gnatc.
18488 (Try_Object_Operation): If no candidate interpretation succeeds, but
18489 there is at least one primitive operation with the right name, report
18490 error in call rather than on a malformed selected component.
18491 (Analyze_Selected_Component): If the prefix is an incomplete type from
18492 a limited view, and the full view is available, use the full view to
18493 determine whether this is a prefixed call to a primitive operation.
18494 (Operator_Check): Verify that a candidate interpretation is a binary
18495 operation before checking the type of its second formal.
18496 (Analyze_Call): Add additional warnings for function call contexts not
18497 yet supported.
18498 (Analyze_Allocator): Move the check for "initialization not allowed for
18499 limited types" after analyzing the expression. This is necessary,
18500 because OK_For_Limited_Init looks at the structure of the expression.
18501 Before analysis, we don't necessarily know what sort of expression it
18502 is. For example, we don't know whether F(X) is a function call or an
18503 indexed component; the former is legal in Ada 2005; the latter is not.
18504 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18505 were missing. We also didn't handle qualified expressions. Now also
18506 allow function calls. Use new common routine OK_For_Limited_Init.
18507 (Analyze_Type_Conversion): Do not perform some legality checks in an
18508 instance, because the error message will be redundant or spurious.
18509 (Analyze_Overloaded_Selected_Component): Do not do style check when
18510 setting an entity, since we do not know it is the right entity yet.
18511 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18512 (Analyze_Overloaded_Selected_Component): Same change
18513 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18514 since regular incomplete subtypes are transformed into corresponding
18515 subtypes of their full views.
18516 (Complete_Object_Operation): Treat name of transformed subprogram call
18517 as coming from source, for browsing purposes.
18518 (Try_Primitive_Operation): If formal is an access parameter, compare
18519 with base type of object to determine whether it is a primitive
18520 operation.
18521 (Operator_Check): If no interpretation of the operator matches, check
18522 whether a use clause on any candidate might make the operation legal.
18523 (Try_Class_Wide_Operation): Check whether the first parameter is an
18524 access type whose designated type is class-wide.

18529
18530 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18531 warn on infinite loops.
18532 Add \\ to some continuation messages
18533 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18534 (Process_Bounds): If the bounds are integer literals that result from
18535 constant-folding, and they carry a user-defined type, preserve that type
18536 rather than treating this as an integer range.
18537 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18538 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18539 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18540 left hand side of assignment.
18541 (Analyze_Assignment): Add suport to manage assigments to the attribute
18542 priority of a protected object.
18543 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18544 not just identifiers.
18545 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18546 or AND THEN for possible tracking.
18547 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18548 case of while loops so we can track values in the loop body.

70198b9f
AC		 18554 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18555 procedure cannot be a protected operation (it is a basic_declaration,
18556 not a subprogram_declaration).
18557 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18558 Subp. Add logic for entry processing.
18559 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18560 Determine whether an entry or subprogram of a protected or task type
18561 override an inherited primitive of an implemented interface.
18562 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18563 Update the actual used in calls to Check_Overriding_Indicator.
18564 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18565 generate the proper reference to the parent unit, for cross-reference.
18566 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18567 Is_Formal.
18568 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18569 (Add_Extra_Formal): Revise procedure to allow passing in associated
18570 entity, scope, and name suffix, and handle setting of the new
18571 Extra_Formals field.
18572 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18573 pass new parameters. Add support for adding the new extra access formal
18574 for functions whose calls are treated as build-in-place.
18575 (Analyze_A_Return_Statement): Correct casing in error message.
18576 Move Pop_Scope to after Analyze_Function_Return, because an extended
18577 return statement really is a full-fledged scope. Otherwise, visibility
18578 doesn't work right. Correct use of "\" for continuation messages.
18579 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18580 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18581 the node doesn't get properly marked as analyzed.
18582 (Analyze_Subprogram_Body): If subprogram is a function that returns
18583 an anonymous access type that denotes a task, build a Master Entity
18584 for it.

18586 proper usage of null exclusion in a result definition.
18587 (Process_Formals): Code cleanup and new error message.

18591 generated for entities that have null exclusions applied to them.
18592 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18593 base type is an access subtype. This case arrises with null exclusions.
18594 (New_Overloaded_Entity): Do not remove the overriden entity from the
18595 homonym chain if it corresponds with an abstract interface primitive.

18614 package, install private_with_clauses of enclosing compilation unit if
18615 we are in its visible part.
18616 (Declare_Inherited_Private_Subprograms): Complete barrier
18617 to ensure that the primitive operation has an alias to some parent
18618 primitive. This is now required because, after the changes done for the
18619 implementation of abstract interfaces, the contents of the list of
18620 primitives has entities whose alias attribute references entities of
18621 such list of primitives.
18622 (Analyze_Package_Specification): Simplify code that handles parent units
18623 of instances and formal packages.
18624 (Uninstall_Declarations): Check the convention consistency among
18625 primitive overriding operations of a tagged record type.

18657 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18658 Determine whether an entity is inside a generic scope.
18659 (In_Open_Scope): First pass of documentation update.

18674 inherited operations created by an unrelated type derivation.
18675 (Check_Overriding_Indicator): When checking for the presence of "null"
18676 in a procedure, ensure that the queried node is a procedure
18677 specification.

18679 type when the formal is an access to variable.
18680 (Analyze_Protected_Type): Add check for Preelaborable_Initialization

18699 to a function with a controlling result of a limited type. This is a
18700 current implementation restriction.
18701 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18702 (Check_Dispatching_Operation): Do no emit a warning if the controlling

AC		 19013 This is a significant redesign primarily for the sake of automatic
19014 timer task termination but also to fix a design flaw.

19016 object, to provide mutual exclusion to the queue of pending events
19017 and the type Timing_Event is no longer a protected type.

20204 (Tree_Read): Change the way of reading Tree_Version_String - now we
20205 read the version string from the tree even if its length is not the

20238 whose ancestor has discriminants.

20266 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20267 does not exist in the Ada RM.
20268 (Compatible_Int_Bounds): Determine whether two integer range bounds

20270 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20271 (Build_Record_Aggr_Code): Perform proper sliding of a nested array

20283 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20284

20293 availability of RE_Interface_Tag.
20294 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20295 (Freeze_Record_Type): Do not generate the tables associated with
20296 timed and conditional dispatching calls through synchronized
20297 interfaces if compiling under No_Dispatching_Calls restriction.
20298 When compiling for Ada 2005, for a nonabstract
20299 type with a null extension, call Make_Controlling_Function_Wrappers
20300 and insert the wrapper function declarations and bodies (the latter
20301 being appended as freeze actions).
20302 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20303 predefined primitives associated with timed and conditional
20304 dispatching calls through synchronized interfaces if we are
20305 compiling under No_Dispatching_Calls.
20306 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20307 service is available before generating a call.
20308 (Make_Controlling_Function_Wrappers): New procedure.
20309 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20310 access-to-limited-interfaces because they can be used to reference
20311 tasks that implement such limited interface.
20312 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20313 procedure spec and body of the Offset_To_Top function that is generated
20314 when the parent of a type with discriminants has secondary dispatch
20315 tables.
20316 (Init_Secondary_Tags): Handle the case in which the parent of the type
20317 containing secondary dispatch tables has discriminants to generate the
20318 correct arguments to call Set_Offset_To_Top.
20319 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20320
20321 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20322 Add Wide_[Wide_]Expanded_Name.
20323 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20324 the same functionality of Get_Prim_Op_Address but applied to predefined
20325 primitive operations because the pointers to the predefined primitives
20326 are now saved in a separate table.
20327 (Parent_Size): Modified to get access to the separate table of primitive
20328 operations or the parent type.
20329 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20330 functionality of Set_Prim_Op_Address but applied to predefined primitive
20331 operations.
20332 (Set_Signature): New subprogram used to store the signature of a DT.
20333 (Displace): If the Offset_To_Top value is not static then call the
20334 function generated by the expander to get such value; otherwise use
20335 the value stored in the table of interfaces.
20336 (Offset_To_Top): The type of the actual has been changed to Address to
20337 give the correct support to tagged types with discriminants. In this
20338 case this value is stored just immediately after the tag field.
20339 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20340 offset_to_top value is static and hence pass this value to the run-time
20341 to store it in the table of interfaces, or else if this value is dynamic
20342 and then pass to the run-time the address of a function that is
20343 generated by the expander to provide this value for each object of the
20344 type.
20345
20346 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20347 (Default_Prim_Op_Count): New entity
20348 (Get_Predefined_Prim_Op_Address): New entity
20349 (Set_Predefined_Prim_Op_Address): New entity

20355 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20356 Make_Adjust_Call done for a newly-allocated object.
20357
20358 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20359 in a subprogram are wrapped in a cleanup block, indicate that the
20360 subprogram contains an inner block with an exception handler.
20361 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20362 Adjust call is for a newly-allocated object. In that case we must not
20363 assume that the finalization list chain pointers are correct (since they
20364 come from a bit-for-bit copy of the original object's pointers) so if
20365 the attach level would otherwise be zero (no change), we set it to 4
20366 instead to cause the pointers to be reset to null.
20367
20368 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20369 reset chain pointers to null.
20370
203712006-02-13 Ed Schonberg <schonberg@adacore.com>
20372
20373 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20374 string, and the context requires a loop for the assignment (e.g.
20375 because the left-hand side is packed), generate a unique name for the
20376 temporary that holds the string, to prevent spurious name clashes.

20382
20383 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20384 return unconstrained arrays.
20385 Update comments.
20386 (Expand_Call): An indirect call through an access parameter of a
20387 protected operation is not a protected call.
20388 Add circuit to raise CE in Ada 2005 mode following call
20389 to Raise_Exception.
20390 (Register_DT_Entry): Do nothing if
20391 the run-time does not give support to abstract interfaces.
20392 (Freeze_Subprogram): In case of dispatching operations, do not generate
20393 code to register the operation in the dispatch table if the source
20394 is compiled with No_Dispatching_Calls.
20395 (Register_Predefined_DT_Entry): Generate code that calls the new
20396 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20397 Set_Prim_Op_Address.
20398
20399 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20400 on array assignments if the right-hand side is a function call that has
20401 been inlined. Check is performed on the assignment in the block.
20402 (Process_Bounds): If bounds and range are overloaded, apply preference
20403 rule for root operations to disambiguate, and diagnose true ambiguity.
20404 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20405 a tag-indeterminate right-hand side even when Expander_Active is True.
20406 Needed to ensure that dispatching calls to T'Input are allowed and
20407 get the tag of the target class-wide object.
20408
20409 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20410 an inherited primitive operation that already overrides several
20411 abstract interface primitives. For transitivity, the new entity must
20412 also override all the abstract interface primitives covered by the
20413 inherited overriden primitive.
20414 Emit warning if new entity differs from homograph in same scope only in
20415 that one has an access parameter and the other one has a parameter of
20416 a general access type with the same designated type, at the same
20417 position in the signature.
20418 (Make_Inequality_Operator): Use source locations of parameters and
20419 subtype marks from corresponding equality operator when creating the
20420 tree structure for the implicit declaration of "/=". This does not
20421 change anything in behaviour except that the decoration of the
20422 components of the subtree created for "/=" allows ASIS to get the
20423 string images of the corresponding identifiers.
20424 (Analyze_Return_Statement): Remove '!' in warning message.
20425 (Check_Statement_Sequence): Likewise.
20426 (Analyze_Subprogram_Body): For an access parameter whose designated type
20427 is an incomplete type imported through a limited_with clause, use the
20428 type of the corresponding formal in the body.
20429 (Check_Returns): Implicit return in No_Return procedure now raises
20430 Program_Error with a compile time warning, instead of beging illegal.
20431 (Has_Single_Return): Function returning unconstrained type cannot be
20432 inlined if expression in unique return statement is not an identifier.
20433 (Build_Body_To_Inline): It is possible to inline a function call that
20434 returns an unconstrained type if all return statements in the function
20435 return the same local variable. Subsidiary procedure Has_Single_Return
20436 verifies that the body conforms to this restriction.
20437
20438 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20439 same type, and one of them is of an anonymous access type, convert
20440 the other operand to it, so that this is a valid binary operation for
20441 gigi.
20442 (Resolve_Type_Conversion): Handle subtypes of protected types and
20443 task types when accessing to the corresponding record type.
20444 (Resolve_Allocator): Add '\' in 2-line warning message.
20445 Remove '!' in warning message.
20446 (Resolve_Call): Add '\' in 2-line warning message.
20447 (Valid_Conversion): Likewise.
20448 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20449 resulting type may be an access type with an implicit dereference.
20450 Obtain the proper component from the designated type.
20451 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20452 given by an expanded name with prefix Standard, when the operands are
20453 of an anonymous access type.
20454 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20455 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20456 prefix of the expression is not of an incomplete type. Allows full
20457 diagnoses of all semantic errors.
20458 (Resolve_Actuals): If the actual is an allocator whose directly
20459 designated type is a class-wide interface we build an anonymous
20460 access type to use it as the type of the allocator. Later, when
20461 the subprogram call is expanded, if the interface has a secondary
20462 dispatch table the expander will add a type conversion to force
20463 the displacement of the pointer.
20464 (Resolve_Call): If a function that returns an unconstrained type is
20465 marked Inlined_Always and inlined, the call will be inlined and does
20466 not require the creation of a transient scope.
20467 (Check_Direct_Boolean_Op): Removed
20468 (Resolve_Comparison_Op): Remove call to above
20469 (Resolve_Equality_Op): Remove call to above
20470 (Resolve_Logical_Op): Inline above, since this is only call.
20471 (Valid_Conversion): Handle properly conversions between arrays of
20472 convertible anonymous access types.

AC		 20475 (Set_Literal_String_Subtype): If the lower bound is not static, wrap

20494 Check No_Dispatching_Calls restriction.
20495 (Default_Prim_Op_Position): Remove the code that looks for the last
20496 entity in the list of aliased subprograms. This code was wrong in
20497 case of renamings.
20498 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20499 when the source is compiled with the No_Dispatching_Calls restriction.
20500 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20501 if we are compiling with restriction No_Dispatching_Calls.
20502 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20503 subprograms if we are compiling under No_Dispatching_Calls restriction.
20504 (Make_DT): Generate a dispatch table with a single dummy entry if
20505 we are compiling with the No_Dispatching_Calls restriction. In
20506 addition, in this case we don't generate code that calls to the
20507 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20508 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20509 of this subprogram if compiling with the No_Dispatching_Calls
20510 restriction.
20511 (Expand_Type_Conversion): Instead of using the actual parameter,
20512 the argument passed as parameter to the conversion function was
20513 erroneously referenced by the expander.
20514 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20515 Set_Predefined_Primitive_Op_Address and Set_Signature.
20516 (Expand_Dispatching_Call): Generate call to
20517 Get_Predefined_Prim_Op_Address for predefined primitives.
20518 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20519 predefined primitives.
20520 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20521 primitives we reserve one dummy entry to ensure that the tag does not
20522 point to some memory that is associated with some other object. In
20523 addition, remove all the old code that generated the assignments
20524 associated with the signature of the dispatch table and replace them
20525 by a call to the new subprogram Set_Signature.
20526 (Set_All_DT_Position): Change the algorithm because now we have a
20527 separate dispatch table associated with predefined primitive operations.
20528 (Expand_Interface_Conversion): In case of non-static offset_to_top
20529 add explicit dereference to get access to the object after the call
20530 to displace the pointer to the object.
20531 (Expand_Interface_Thunk): Modify the generation of the actual used
20532 in the calls to the run-time function Offset_To_Top to fulfil its

20611 * g-catiio.adb (Sec_Number): New type used to compute the number of
20612 seconds since 1-1-1970.
20613 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20614 negative numbers (years, months...) it is better to have a Natural here.
20615 Code clean-up.
20616 (Image) [Number]: Change parameter from Long_Integer to Number.
20617 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an

20921 (Try_Primitive_Operations): If context requires a function, collect all
20922 interpretations after the first match, because there may be primitive
20923 operations of the same type with the same profile and different return
20924 types. From code reading.
20925 (Try_Primitive_Operation): Use the node kind to choose the proper
20926 operation when a function and a procedure have the same parameter
20927 profile.
20928 (Complete_Object_Operation): If formal is an access parameter and prefix
20929 is an object, rewrite as an Access reference, to match signature of

21030 Scan_Long_Long_Unsigned out into
21031 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21032 This prevents scanning leading blanks and sign twice.

21264 instead for handling run-time termination in a more flexible way.

21294 Ada.Task_Termination, for avoiding circular dependencies.
21295 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21296 for storing task termination handlers. In addition,
21297 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21298 Common_ATCB because it is used by both the regular and the restricted
21299 run times.

21391 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21392 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21393 record component containing the tag of the secondary dispatch table we
21394 have to use the Offset_To_Top run-time function to get this information;
21395 otherwise if the pointer to the base of the object has been displace
21396 we get a wrong value if we use the 'position attribute.
21397
21398 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21399 all the calls to Expand_Interface_Thunk.
21400 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21401 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21402 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21403 ensure that the interfaces implemented by the ancestors are placed
21404 at the header of the generated list.
21405 (Expand_Interface_Conversion): Handle the case in which the displacement
21406 associated with the interface conversion is not statically known. In
21407 this case we generate a call to the new run-time subprogram Displace.
21408 (Make_DT): Generate and fill the new table of interfaces.

21412 with respect to limitedness and concurrency and returns a reference to
21413 RE_Tagged_Kind.
21414 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21415 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21416 primary dispatch table for a type.
21417 (Make_DT, Make_Secondary_DT): Set the tagged kind in the primary and
21418 secondary dispatch table respectively of a tagged type.

21437 Init_Secondary_Tags_Internal to allow its use with interface types and
21438 also to generate the code for the new additional actual required

21594 base type to create anonymous subtype, because entity may be a locally
21595 declared subtype or generic actual.
21596 (Find_Interface): New subprogram that given a tagged type and one of its
21597 component associated with the secondary table of an abstract interface
21598 type, return the entity associated with such abstract interface type.
21599
21600 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the

21643 (Derived_Type_Declaration): If the parent of the full-view is an
21644 interface perform a transformation of the tree to ensure that it has
21645 the same parent than the partial-view. This simplifies the job of the
21646 expander in order to generate the correct object layout, and it is
21647 needed because the list of interfaces of the full-view can be given in
21648 any order.
21649 (Process_Full_View): The parent of the full-view does not need to be
21650 a descendant of the parent of the partial view if both parents are
21651 interfaces.
21652 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21653 "limited" the parent must be a limited type.

21665 lists of interfaces constitute a set equality. If not, the first
21666 differing interface is returned.
21667 (Process_Full_View): Improve the check for the "no hidden interface"
21668 rule as defined by AI-396.

21681 * gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U
21682 If GNAT CHECK is called with a project file, but with no
21683 source on the command line, call gnatcheck with all the compilable
21684 sources of the project.
21685 Take into account the new command Check, for gnatcheck. Treat as for
21686 other ASIS tools: take into account project, specific package Check and

21726 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
21727 available user-specified stream attributes on limited parameters to
21728 also test the type directly rather than only its underlying type (for
21729 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21730 attributes are visible at the point of the subprogram declaration.
21731 For Ada 2005, the error message is modified to indicate that the
21732 type's stream attributes must be visible (again, only for -gnat05).

22257 generation and we are at the top level, check for a potential violation
22258 of a No_Elaboration_Code restriction.
22259 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

22441 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22442 and related): For a prefix that is an explicit dereference of an

22445 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22446 'Unrestricted_Access, if the designated type is an interface we
22447 add a type conversion to force the displacement of the pointer
22448 to the secondary dispatch table.
22449 Use Universal_Real instead of Long_Long_Float when we need a high
22450 precision float type for the generated code (prevents gratuitous
22451 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)

22474 * exp_ch5.adb (Expand_N_Assignment_Statement, Tagged_Case): For an
22475 assignment of a value of a tagged type that has been rewritten to a
22476 block statement, it is known by construction that no checks are
22477 necessary for the statements within the block: analyze it with checks
22478 suppressed.
22479 (Expand_N_If_Statement): When killing a dead then-branch in an
22480 if-statement that has elsif_parts, recompute the Current_Value node

22483 (Expand_N_Return_Statement): When returning a mutable record, convert
22484 the return value into its actual subtype in order to help the backend

22504 (__gnat_waitpid): Fix implementation, the pid returned by spawnve is
22505 a process handle, not need to convert.

22523 used).

22535 attribute of the N_Free_Statement.
22536 Generate itype for classwide designated object in both cases of
22537 user-specified storage pool: specific and class-wide, not only in the
22538 specific case.
22539 Raise CE when trying to set a not null access type object to null.

22552 requirement under Ada05 mode.
22553

22760 parent scopes of a scope being removed prior to inlining an instance
22761 body.
22762 (Analyze_Package_Instantiation): Do not perform front-end inlining when
22763 the current context is itself an instance within a non-instance child
22764 unit, to prevent scope stack errors.
22765 (Save_References): If the node is an aggregate that is an actual in a
22766 call, rewrite as a qualified expression to preserve some type
22767 information, to resolve possible ambiguities in the instance.
22768 (Instance_Parent_Unit): New global variable to record the ultimate
22769 parent unit associated with a generic child unit instance (associated
22770 with the existing Parent_Unit_Visible flag).

22778 scope against package Standard. Add comments and a ??? comment.
22779 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22780 on a child instance parent to test that the parent equals
22781 Instance_Parent rather than simply checking that the unit is not a

22797 (Build_Private_Derived_Type): The entity of the created full view of the
22798 derived type does not come from source. If after installing the private
22799 declarations of the parent scope the parent is still private, use its
22800 full view to construct the full declaration of the derived type.
22801 (Build_Derived_Record_Type): Relax the condition that controls the
22802 execution of the check that verifies that the partial view and
22803 the full view agree in the set of implemented interfaces. In
22804 addition, this test now only takes into account the progenitors.
22805 (Derive_Interface_Subprograms): No need to derive subprograms
22806 of ancestors that are interfaces.

22811 view is a transitive derivation of the ancestor of the partial view.
22812 (Process_Full_View): Rename local subprogram Find_Interface_In_
22813 Descendant to Find_Ancestor_Interface to leave the code more clear.
22814 Remove wrong code that avoids the generation of an error message
22815 when the immediate ancestor of the partial view is an interface.
22816 In addition some minor reorganization of the code has been done to
22817 leave it more clear.
22818 (Analyze_Type_Declaration): If type has previous incomplete tagged
22819 partial view, inherit properly its primitive operations.
22820 (Collect_Interfaces): Make public, for analysis of formal
22821 interfaces.
22822 (Analyze_Interface_Declaration): New procedure for use for regular and
22823 formal interface declarations.
22824 (Build_Derived_Record_Type): Add support for private types to the code
22825 that checks if a tagged type implements abstract interfaces.
22826 (Check_Aliased_Component_Type): The test applies in the spec of an
22827 instance as well.
22828 (Access_Type_Declaration): Clean up declaration of malformed type
22829 declared as an access to its own classwide type, to prevent cascaded
22830 crash.
22831 (Collect_Interfaces): For private extensions and for derived task types
22832 and derived protected types, the parent may be an interface that must
22833 be included in the interface list.
22834 (Access_Definition): If the designated type is an interface that may
22835 contain tasks, create Master_Id for it before analyzing the expression
22836 of the declaration, which may be an allocator.
22837 (Record_Type_Declaration): Set properly the interface kind, for use
22838 in allocators, the creation of master id's for task interfaces, etc.

22843 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
22844 omitted in case of stream attribute subprograms.
22845 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
22846 appear immediately after a subprogram body, when there is no previous
22847 subprogram declaration.
22848 Change name Is_Package to Is_Package_Or_Generic_Package
22849 (Process_Formals): A non null qualifier on a non null named access
22850 type is not an error, and is a warning only if Redundant_Constructs
22851 are flagged.

22858 declarations and use clauses within each of the parent units of a
22859 package instance of a generic child package.
22860 (Analyze_Package_Specification): When entering a private part of a
22861 package associated with a generic instance or formal package, the
22862 private declarations of the parent must be installed (by calling new
22863 procedure Install_Parent_Private_Declarations).
22864 Change name Is_Package to Is_Package_Or_Generic_Package
22865 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22866 record is absent in a generic context, which does not indicate a
22867 compiler error.

22871 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22872 not try to rewrite a renamed stream attribute, because the operations
22873 on the type may not have been generated.
22874 Handle properly a renaming_as_body generated for a stream operation
22875 whose default is abstract because the object type itself is abstract.
22876 (Find_Type): If the type is incomplete and appears as the prefix of a
22877 'Class reference, it is tagged, and its list of primitive operations
22878 must be initialized properly.
22879 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22880 private declaration of a parent unit, prior to compiling the private
22881 part of a child unit, find on the scope stack the proper parent entity
22882 on which to link the use clause.
22883 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22884 detected.
22885 (Analyze_Object_Renaming): An attribute reference is not a legal object

22905 (Valid_Conversion): If the operand has a single interpretation do not
22906 remove address operations.
22907 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22908 statement to inhibit warning.
22909 (Resolve_Unary_Op): Do not produce a warning when
22910 processing an expression of the form -(A mod B)
22911 Use Universal_Real instead of Long_Long_Float when we need a high
22912 precision float type for the generated code (prevents gratuitous
22913 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22914 (Resolve_Concatenation_Arg): Improve error message when argument is an
22915 ambiguous call to a function that returns an array.
22916 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23748 gsocket.h, in order to ensure that any C code in socket.c will see a
23749 set of constants that is consistent with the contents of g-soccon.ads.
23750
23751 * gsocket.h: Code imported from gen-soccon.c:
23752 Move all target-specific file inclusions and macro definitions to
23753 gsocket.h, in order to ensure that any C code in socket.c will see a set
23754 of constants that is consistent with the contents of g-soccon.ads.
23755 This change also makes gen-soccon self-contained (removing dependencies
23756 upon GCC internal headers).

24122 the package was already analyzed the new algorithm "replaces" the
24123 real entities by the shadow ones. This is required to ensure that
24124 the order of these entities in the homonym chains does not change;
24125 otherwise we can have undefined references at linking time because
24126 in case of conflicts the external name of the entities will have
24127 a suffix that depends on the order of the entities in the chain.
24128 (Remove_Limited_With_Clause): Complementary code that completes the
24129 new algorithm and replaces the shadow entities by the real ones.
24130 (Install_Limited_Withed_Unit): When unchaining entities before the
24131 installation of the shadow entities, only regular entities of the

24173 underlying type
24174 to check if a type is Constrained in cases related to code generation
24175 (rather than semantic checking) since otherwise we do not generate
24176 similar code for mutable private types depending if their
24177 discriminants are visible or not.
24178 (Check_Abstract_Overriding): Do not complain about failure to override
24179 the primitive operations used in dispatching selects since they will
24180 always be overriden at the freeze point of the type.
24181 (Access_Definition): Separate out handling for resetting the scope
24182 of an anonymous access function result type. Retrieve the scope
24183 of the associated function rather than using Current_Scope, which
24184 does not have a consistent value (depends on whether we're in the
24185 middle of analyzing formal parameters). Add ??? comment about
24186 finding a cleaner way to handle the special cases of scope setting.
24187 (Process_Incomplete_Dependents): A protected operation is never a
24188 dispatching operation (only its wrapper may be).
24189 (Build_Derived_Record_Type): In case of tagged private types that
24190 implement interfaces add derivation of predefined primitive
24191 operations.
24192 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24193 by two parameters that are used in case of derivation from abstract
24194 interface types: No_Predefined_Prims is used to avoid the derivation
24195 of predefined primitives from the interface, and Predefined
24196 Prims_Only is used to complete the derivation predefined primitives
24197 in case of private tagged types implementing interfaces.
24198 Fix typo in comments
24199 (Find_Interface_In_Descendant): Protect the frontend against
24200 wrong code with large circularity chains.
24201 (Is_Private_Overriding): Add support for entities overriding interface
24202 subprograms. The test failed because Entities associated with overriden
24203 interface subprograms are always marked as hidden (and used to build
24204 the secondary dispatch table); in this case the overriden entity is
24205 available through the field abstract_interface_alias (cf. override_
24206 dispatching_operation)
24207 (Access_Definition): Set the scope of the type to Current_Scope for the
24208 case of a function with an anonymous access result type.

24270 type, apply a conversion of the return expression to the access type
24271 to ensure that appropriate accessibility checks are performed.
24272 (Analyze_Return_Type): For the case of an anonymous access result type,
24273 generate the Itype and set Is_Local_Anonymous_Access on the type.
24274 Add ??? placeholder for check to disallow returning a limited object
24275 in Ada 2005 unless it's an aggregate or a result of a function call.

24284 (New_Overloaded_Entity): For an entity overriding an interface primitive
24285 check if the entity also covers other abstract subprograms in the same
24286 scope. This is required to handle the general case, that is, overriding
24287 other interface primitives and overriding abstract subprograms inherited
24288 from some abstract ancestor type.
24289 (New_Overloaded_Entity): For an overriding entity that comes from
24290 source, note the operation that it overrides.

24323 the expression.
24324 (Resolve_Call): Check for legal type of procedure name or prefix that

24326 (Valid_Conversion): If expression is ambiguous and the context involves
24327 an extension of System, remove System.Address interpretations.
24328 (Resolve_Qualified_Expression): Reject the case of a specific-type
24329 qualification applied to a class-wide argument. Enhance comment
24330 to explain checking of Original_Node.
24331 (Resolve_Type_Conversion): The location of the error message was not

24334 (Resolve_Type_Conversion): Add missing support for access to interface
24335 types.
24336 (Resolve_Type_Conversion): If the target is a class-wide interface type,

24338 expansion will take place when the call itself is expanded.
24339 (Resolve_Allocator): If the context is an unchecked conversion, the

24349 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24350 use the Corresponding_Record_Typ attribute to look for the interface
24351 because it is set by the expander (and hence it is not always
24352 available). For this reason we traverse the list of interfaces

25156
25157 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25158 longer protected objects. They have been replaced by lower-level
25159 suspension objects made up by a mutex and a condition variable (or
25160 their equivalent given a particular OS) plus some internal data to
25161 reflect the state of the suspension object.
25162 (Initialize, Finalize): Add this initialization procedure for
25163 Suspension_Object, which is a controlled type.
25164 (Finalize): Add the finalization procedure for Suspension_Object,
25165 which is a controlled type.
25166
25167 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25168 Ada.Synchronous_Task_Control because there is no longer a need for a
25169 VxWorks specific version of this package. Target dependencies

25171
25172 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25173 longer needed.
25174 (InitializeCriticalSection, EnterCriticalSection,

25186 suspension object.
25187 (Set_False): Add this procedure that sets the state of the suspension
25188 object to False.
25189 (Set_True): Add this procedure that sets the state of the suspension
25190 object to True, releasing the task that was suspended, if any.
25191 (Suspend_Until_True): Add this procedure that blocks the calling task
25192 until the state of the object is True. Program_Error is raised if
25193 another task is already waiting on that suspension object.
25194 (Initialize): Add this procedure for initializing the suspension
25195 object. It initializes the mutex and the condition variable which are
25196 used for synchronization and queuing, and it sets the internal state
25197 to False.
25198 (Finalize): Add this procedure for finalizing the suspension object,
25199 destroying the mutex and the condition variable.

25205 which provides a low-level abstraction (using operating system
25206 primitives) for Ada.Synchronous_Task_Control.
25207 This object is made up by a mutex (for ensuring mutual exclusion), a
25208 condition variable (for queuing threads until the condition is
25209 signaled), a Boolean (State) indicating whether the object is open,
25210 and a Boolean (Waiting) reflecting whether there is a task already
25211 suspended on this object.

25419 same functionality and it is more clear in case of primitives
25420 associated with abstract interfaces.
25421 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
25422 clean up, the functionality of this subprogram is now provided
25423 by Set_All_DT_Position.

25436 the object to give access to the interface tag associated with the
25437 secondary dispatch table.
25438 (Expand_Interface_Thunk): New subprogram that generates the code of the
25439 thunk. This is required for compatibility with the C+ ABI.

25467 access component.
25468 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
25469 an access component in this context is a Local_Anonymous_Access, for

25488 declared in the formal part of an enclosing generic.
25489 (Analyze_Object_Declaration): For protected objects, remove the check
25490 that they cannot contain interrupt handlers if not declared at library
25491 level.

25519
25520 * exp_ch3.adb: Implement config version of persistent_bss pragma

25524 Make_Abstract_Interfaces_DT to generate the secondary tables
25525 associated with abstract interfaces.
25526 (Build_Init_Procedure): Modified to initialize all the tags
25527 corresponding.

25533 a scalar temporary marked as internal.
25534
25535 * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an
25536 in-out parameter that is a component in an initialization procedure,
25537 whose constraint might depend on discriminants, and that may be
25538 misaligned because of packing or representation clauses.
25539 (Is_Legal_Copy): New predicate to determine whether a possibly
25540 misaligned in-out actual can actually be passed by copy/return. This
25541 is an error in case the type is by_reference, and a warning if this is
25542 the consequence of a DEC import pragma on the subprogram.
25543 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
25544 interface types
25545 (Expand_Inlined_Call): Mark temporary generated for the return value as
25546 internal, so that no useless scalar normalization is generated for it.

25548 null procedure can always be inlined.
25549 (Expand_N_Subprogram_Declaration): If this is the declaration of a null
25550 procedure, generate an explicit empty body for it.
25551

25556 interface, returns the record component containing the tag of the
25557 interface.

25560 entities.
25561 (Is_Predefined_Dispatching_Operation): Determines if a subprogram
25562 is a predefined primitive operation.
25563 (Expand_Subtype_From_Expr): If the expression is a selected component
25564 within an initialization procedure, compute its actual subtype, because
25565 the component may depend on the discriminants of the enclosing record.

0adcdb66
AC		 25568 This package has been left available for compatibility with previous
25569 versions of the frontend. As part of the new layout this is now a
25570 dummy package that uses declarations available at a-tags.ads
25571
25572 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of
25573 "constant access" and "aliased [constant] access" when not compiling
25574 with -gnat05.

25593 the generic that is created to represent the formal package.
25594 (Analyze_Package_Instantiation): Instantiate body immediately if the

25601 error message condition, null procedures are correctly detected now.
25602 (New_Overloaded_Entity): Bypass trivial overriding indicator check
25603 for subprograms in the context of protected types. Instead, the
25604 indicator is examined in Sem_Ch9 while analysing the subprogram
25605 declaration.
25606 (Check_Overriding_Indicator): Check consistency of overriding indicator
25607 on subprogram stubs as well.
25608 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
25609 the library level.
25610 (Analize_Subprogram_Specification): When analyzing a subprogram in which
25611 the type of the first formal is a concurrent type, replace this type
25612 by the corresponding record type.
25613 (Analyze_Subprogram_Body): Undo the previous work.
25614 (Analyze_Procedure_Call): If the call has the form Object.Op, the
25615 analysis of the prefix ends up analyzing the call itself, after which
25616 we are done.
25617 (Has_Interface_Formals): New subprogram subsidiary to analyze
25618 subprogram_specification that returns true if some non
25619 class-wide interface subprogram is found
25620 (New_Overloaded_Entity): Modified to give support to abstract
25621 interface types
25622 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
25623 access to subprograms must be recursive.
25624 (Is_Unchecked_Conversion): Improve the test that recognizes
25625 instantiations of Unchecked_Conversion, and allows them in bodies that
25626 are to be inlined by the front-end. When the body comes from an
25627 instantiation, a reference to Unchecked_Conversion will be an
25628 Expanded_Name, even though the body has not been analyzed yet.
25629 Replace Is_Overriding and Not_Overriding in subprogram_indication with
25630 Must_Override and Must_Not_Override, to better express intent of AI.
25631 (Analyze_Subprogram_Body): If an overriding indicator is given, check

25645 to give support to abstract interface types
25646
25647 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
25648 in the case where the target type is an anonymous access type of an
25649 object or component (that is, when Is_Local_Anonymous_Access is true).
25650 Prevent the special checks for conversions of access discriminants in
25651 the case where the discriminant belongs to a nonlimited type, since
25652 such discriminants have their accessibility level defined in the same
25653 way as a normal component of an anonymous access type.
25654 (Resolve_Allocator): When an allocator's designated type is a class-wide
25655 type, check that the accessibility level of type given in the

25664 types.
25665 (Valid_Tagged_Conversion): The conversion of a tagged type to an

25668 (Resolve_Actuals): Enable full error reporting on view conversions
25669 between unrelated by_reference array types.
25670 The rule for view conversions of arrays with aliased components is
25671 weakened in Ada 2005.
25672 Call to obsolescent subprogram is now considered to be a violation of
25673 pragma Restrictions (No_Obsolescent_Features).
25674 (Check_Direct_Boolean_Operator): If the boolean operation has been
25675 constant-folded, there is nothing to check.
25676 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25677 check on possible violation of restriction No_Direct_Boolean_Operators
25678 until after expansion of operands, to prevent spurious errors when
25679 operation is constant-folded.

25692 2005 users.
25693 (Analyze_Allocator): For an allocator without an initial value, where
25694 the designated type has a constrained partial view, a discriminant
25695 constraint is illegal.

25713 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25714 both bound checks, rather than a conjunction.
25715 (Insert_Valid_Check): If the expression is an actual that is an indexed
25716 component of a bit-packed array, force expansion of the packed element
25717 reference, because it is specifically inhibited elsewhere.

25730 may be deallocated by Normalize_Arguments.
25731 (Collect_Arguments): Eliminate empty arguments
25732
25733 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
25734 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.
25735 (Check_Project): Return False when Project is No_Project. Return True
25736 when All_Projects is True.

25777 Has_Specified_Stream_Write (Flag193)
25778 Present in all type and subtype entities. Set for a given view if the
25779 corresponding stream-oriented attribute has been defined by an
25780 attribute definition clause. When such a clause occurs, a TSS is set

25805
25806 * freeze.adb (Freeze_Entity): Issue error message if

25831 (Has_Overriding_Pragma): Remove obsolete implementation of AI-218.
25832 Declare_Inherited_Private_Subprograms): If an explicit operation

25848 actual (if it is constrained), and only finally reading the components
25849 into a constrained temporary object.
25850 (Build_Elementary_Input_Call): Adjust the specific circuitry for the
25851 case of reading discriminants of a mutable record type to recognize

25861 Is_Local_Anonymous_Access to check legaliy of attributes in the
25862 context of access components and stand-alone access objects.
25863 (Stream_Attribute_Available): In Ada 95 mode, a stream attribute is
25864 treated as available for a limited private type if there is an
25865 attribute_definition_clause that applies to its full view, but not in

25867 (specifically, the sole fact that the full view is non-limited does not
25868 make the attribute available for the partial view).

25893 be rejected, as mandated by AI-195 item 5.
25894
25895 * sem_util.ads, sem_util.adb (Type_Access_Level): Use flag

25958 * exp_aggr.adb (Aggr_Size_OK): An array with no components can always
25959 be expanded in place. The size computation does not require a
25960 subtraction, which would raise an exception on a compiler built with
25961 assertions when the upper bound is Integer'first.
25962 (Flatten): For an array of composite components, take into account the
25963 size of the components to determine whether it is safe to expand the

28154
28155 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
28156 "dispatching" rather than "primitive" operations, since dispatching
28157 calls are now allowed to abstract formal subprograms (which are not
28158 primitive).
28159 Char_Literal_Value field is now a Uint
28160 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28161 compute the actual subtype of the designated object to impose the proper
28162 index constraints.
28163 (Resolve_Selected_Component): Do not insert an access check if the
28164 prefix is an access type: such a node is expanded into an explicit
28165 dereference, on which the access check is performed anyway. Removes
28166 expensive duplicate checks.

28168 Obsolescent_Warning so that pragma Obsolescent works on library
28169 subprograms.

28171 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28172 value by a warning message.
28173 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28174 as fixed-point, and one of the operands is non-static and universal, it
28175 can only be an illegal exponentiation operation, in which case there is
28176 no real value to retrieve.
28177
28178 * exp_strm.adb: Add support for wide wide character type
28179 (Build_Elementary_Input_Call): Compute the size of the stream element by

28194
28195 * sem_ch3.adb: Add support for wide wide character type
28196 (Process_Subtype): If constraint is illegal for the type, set Ekind of
28197 now-useless Itype, to prevent cascaded errors on a compiler built
28198 without -gnatp.
28199
28200 * sem_ch8.adb: Add with and use of Sem_Disp.
28201 (Analyze_Subprogram_Renaming): Replace unclean uses of
28202 Corresponding_Spec with Corresponding_Formal_Spec (and delete setting
28203 of Corresponding_Spec to Empty).
28204 (Attribute_Renaming): Replace use of Corresponding_Spec with
28205 Corresponding_ Formal_Spec and simplify condition.
28206 (Use_One_Package): Check that scope of homonym of identifier is defined,
28207 before checking whether it is a wrapper package.
28208 Add support for wide wide character type
28209
28210 * sem_eval.adb: Add support for wide wide character type.
28211 (Eval_Arithmetic_Op): Check for compile time known signed integer
28212 overflow in the non-static case.
28213 (Subtypes_Statically_Match): A formal scalar type and its base type do
28214 not statically match.
28215
28216 * sem_util.adb (Collect_Primitive_Operations): Minor change of "/=" to
28217 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28218 subtype).
28219 (Unit_Declaration_Node): Ditto.
28220 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28221 has a packed array type, the prefix has been rewritten into a type

28224
28225 * stand.ads: Add types Wide_Wide_Character and Wide_Wide_String
28226
28227 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28228 Remove ["0A"] from comment, since it can look like a line terminator.
28229 Currently we don't permit this, but this is under discussion by the
28230 ARG, and it is easy enough to use a different example.
28231
28232 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28233 handling UTF-32 encoding for wide wide character.

28241 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28242 notify that constraint error will be raised at run-time
28243 because a null value is assigned to a null-excluding object.
28244 Remove some obsolete declarations and make Char_Code
28245 unsigned.
28246
28247 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28248 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28249 Rcheck subprograms.

28252 wrong null-exclusion value by a warning message.
28253 (Enable_Range_Check): Do range check if the prefix is an
28254 explicit dereference whose designated object is an unconstrained array.
28255 Current algorithm for removing duplicate checks is over-eager in this
28256 case.
28257
28258 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
28259 null-exclusion value by a warning message
28260

28271
28272 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28273 defined for subprogram renaming declarations. When set, the field
28274 indicates the defining entity of a corresponding formal subprogram
28275 when the renaming corresponds to a formal subprogram association in an
28276 instantiation.
28277 (Set_Corresponding_Formal_Spec): New procedure to return
28278 Corresponding_Formal_Spec field.
28279 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

28287 associated with a tagged primitive subprogram.
28288 (Expand_Dispatching_Call): Add support for a controlling actual that is
28289 directly a value of type Ada.Tag rather than a tagged object.
28290
28291 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28292 describing the new layout.
28293 (Dispatch_Table): The expander computes the actual array size, allocates
28294 the Dispatch_Table record accordingly, and generates code that displaces
28295 the base of the record after the Typeinfo_Ptr component. The access to
28296 these components is done by means of local functions.
28297 (Offset_To_Top): New function.
28298 (Typeinfo_Ptr): New function.
28299 (Get_TSD): Modified to access the new position of the TSD.

28310 N_Formal_Subtype_Declaration (which is now a subtype).
28311 (Analyze_Formal_Subprogram): Add handling for
28312 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28313 dispatching, setting the controlling status of the formal parameters
28314 and result, and issuing an error if there is no controlling type for
28315 the formal subprogram.
28316 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28317 which is an unclean use of that field, we set the new field
28318 Corresponding_Formal_Spec to make the formal subprogram available to
28319 processing in Analyze_Subprogram_Declaration.
28320 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28321 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28322 Constrained, so that it is is does not statically match its anonymous

28326 abstract formal subprograms in error check for functions returning
28327 abstract types. Set scope of new designator for
28328 a parameterless subprogram, so that it is available when checking the
28329 body for nested subprograms, before full analysis of said body.
28330 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28331 subprogram only if inner one comes from source.
28332 (Analyze_Function_Call): If the call is given in object notation, the
28333 analysis of the name rewrites the node and analyzes it with the proper
28334 argument list. After analyzing the name, if the call has been rewritten
28335 and the result type is set, no further analysis is needed.
28336 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28337 mark in function specification, in a context where the formals are
28338 visible and hide outer homographs.
28339
28340 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28341 as the tagged type for the cases of abstract formal subprograms and
28342 renamings of those. Clean up spec comments.

28344 procedure", covering the case of a call to a formal abstract procedure
28345 that has statically tagged operands.
28346 (Check_Dispatching_Call): Check for the case of an actual given by
28347 a tag-indeterminate function call whose type is an ancestor of the
28348 containing call's associated tagged type. This situation can occur
28349 for inherited primitives with function defaults. In this case we
28350 use the tagged type's tag directly as the controlling argument for
28351 the calls.
28352 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28353
28354 * sprint.adb (Sprint_Node_Actual): Split
28355 N_Formal_Subprogram_Declaration into two alternatives for the new

28380 source is loaded.
28381
28382 * errout.adb (Finalize): Do not check Num_SRef_Pragmas
28383 (Main_Source_File) when no main source has been loaded, to avoid
28384 potential crash.

29354 dereference is rewritten to an explicit one, generate a reference to
29355 the entity denoted by its prefix using the original prefix node, so

29357 access value, if appropriate.
29358

29400 for generation of DSA code targeted to the PolyORB PCS.

29471 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29472 used to record an implicit dereference as a read operation on its
29473 prefix when operating under -gnatc. Necessary to avoid spurious
29474 'variable assigned but never read' warnings in that mode.
29475 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29476 is a non-overloaded implicit dereference, call the above subprogram to

29657 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29658 string distribution identifiers assigned to a given subprogram.
29659 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29660 (Add_RAS_Dereference_TSS): Add comments.
29661 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29662 is not referenced yet because it will be used by the PolyORB DSA
29663 implementation.
29664 (Insert_Partition_Check): Remove fossile code.
29665 (First_RCI_Subprogram_Id): Document this constant.
29666 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29667 RAS_Access TSS.
29668 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29669 replaced with calls to Get_Library_Unit_Name_String. Previously there
29670 were several instances of the same code in different locations in the
29671 compiler; this checkin completes the replacement of all of these
29672 instances with calls to a common subprogram.
29673 Minor reformatting.
29674
29675 * sem_dist.adb: Remove comment noting that RPC receiver generation
29676 should be disabled for RACWs that implement RASs.
29677 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29678
29679 * sem_util.ads, sem_util.adb (Has_Stream): New function
29680 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29681 qualified name of a library unit into the name buffer.

29701 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29702 (Expand_Pragma_Psect_Object): New procedure
29703 These procedures contain the revised and cleaned up processing for
29704 these two pragmas. This processing was formerly in Sem_Prag, but
29705 is more appropriately moved here. The cleanup involves making sure
29706 that the pragmas are properly attached to the tree, and that no
29707 nodes are improperly shared.
29708
29709 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29710 pragmas to Exp_Prag, which is more appropriate.
29711 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29712 check for duplicates Remove use of Is_Psected flag, no longer needed.
29713 Use new Make_String_Literal function with string.
29714
29715 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29716 that are functions return universal values, that have to be converted
29717 to the context type.
29718 Use new Make_String_Literal function with string.
29719 (Get_Stream_Convert_Pragma): New function, replaces the use of
29720 Get_Rep_Pragma, which had to be kludged to work in this case.
29721
29722 * freeze.adb: Use new Has_Rep_Pragma function
29723
29724 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29725 function with string.
29726 Use new Has_Rep_Pragma function.

29733 * errout.ads, errout.adb: (First_Sloc): New function
29734
29735 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29736 check (-gnatyx) instead of being included as a redundant construct
29737 warning.
29738
29739 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29740 Style_Check_Order_Subprograms.

29751
29752 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29753 discriminant of a constrained subtype, analyze the copy of the
29754 corresponding constraint, because in some cases it may be only
29755 partially analyzed.
29756 Removes long-lived ??? comments.
29757
29758 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29759 handled controlled or secondary-stack expressions within the
29760 iteration_scheme of a loop.
29761
29762 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29763 bounds that may contain functions calls, to prevent memory leaks when
29764 the bound contains a call to a function that uses the secondary stack.
29765 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29766 generate temporaries for loop bounds that might contain function calls
29767 that require secondary stack and/or finalization actions.
29768
29769 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29770 selected component and the selector is overloadable (not just a
29771 function) treat as function call, Analyze_Call will disambiguate if
29772 necessary.
29773 (Analyze_Selected_Component): Do not generate an actual subtype for the
29774 selected component if expansion is disabled. The actual subtype is only
29775 needed for constraint checks.
29776 (Analyze_Allocator): If restriction No_Streams is set, then do
29777 not permit objects to be declared of a stream type, or of a
29778 composite type containing a stream.
29779
29780 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29781 No_Streams no longer prohibits with'ing this package.
29782
29783 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29784 discriminants, but the parent base has unknown discriminants, there is
29785 no discriminant constraint to inherit. Such a discrepancy can arise
29786 when the actual for a formal type with unknown discriminants is a
29787 similar private type whose full view has discriminants.
29788 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29789 do not permit objects to be declared of a stream type, or of a
29790 composite type containing a stream.

29794 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29795 protected operations.
29796
29797 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29798 generated name, it complicates decoding in gdb and hinders debugging
29799 of protected operations.
29800 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29801 flag for the protected entry barrier function.
29802 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29803 flag for the protected entry function.

29818 type of the object with the packed array type, set the Analyzed flag
29819 on the object if it is an entity or simple indexed component, to avoid
29820 spurious type errors.

29844 procedure Protected_Single_Entry_Call.
29845 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29846 Detect_Blocking which is redundant with the check done within the

29852 Compiler and on the command line) immediately after "-c", instead of
29853 at the end of the command line invocation of the compiler, when
29854 compiling a non-Ada file.
29855 (Build_Global_Archive): When there is no need to rebuild the archive,
29856 set Global_Archive_Exists, so that the archive is passed to the linker
29857 if one is needed.

29898 there is no use of GNAT.Sockets.Constants.
29899 Remove remaining pragma Import for C_Write
29900 Remove C_Read and C_Write from internal implementation unit
29901 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29902 the read and write functions from the system runtime library is fine
29903 on UNIX but won't work under Windows).
29904
29905 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29906 (Check_Selector): Use C_Recv instead of C_Read.
29907 Selectors are the GNAT.Sockets abstraction to perform a select()
29908 call on a set of descriptors. To allow abortion of an ongoing
29909 select operation, some data is written to a dedicated socket that
29910 is always monitored.
29911 Under Windows, the write and read library functions cannot operate
29912 on sockets, so we need to use send and recv instead, which is portable
29913 across all supported platforms.

29964 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29965 sections were just mistakenly ignored. The former is
29966 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.

30027 be expandable in place even if the aggregate does not come from source.
30028 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30029 designated object of an allocator in place, rather than building it
30030 first on the stack. The previous scheme forces a full copy of the array,
30031 and may be altogether unsusable if the size of the array is too large

30174 immediately after its spec, to make its subprogram bodies available
30175 for front-end inlining.

30177 constraint is not allowed on the component type (AARM 12.5.3(3))

30193 or protected type with discriminants, do not constrain the
30194 corresponding record type if the subtype declaration has no
30195 discriminant constraints. This can be the case in source code, or in
30196 the subtype declaration created to rename an actual type within an
30197 instantiation.
30198
301992004-10-26 Ed Schonberg <schonberg@gnat.com>

30202 different kind of stub (possibly wrong name for file), do not check
30203 for conformance.
30204 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30205 includes call to some function that returns an unconstrained type, do
30206 not inline.
30207
302082004-10-26 Ed Schonberg <schonberg@gnat.com>
30209
30210 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30211 appear in the code for the main unit. Dependencies among units in the
30212 context of the main unit are established when those other units are
30213 compiled. Otherwise spurious elaboration constraints can generate
30214 incorrect elaboration circularities.

30217 Ed Schonberg <schonberg@gnat.com>
30218
30219 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30220 subprogram is called with a parameter that is not an object name. This
30221 situation arises for some cases of illegal code, which is diagnosed
30222 later, and in this case it is wrong to call Is_Aliased, as that might
30223 cause a compiler crash.
30224 (Explain_Limited_Type): Refine previous fix to include
30225 inherited components of derived types, to provide complete information.
30226
30227 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30228 is the prival for a protected object.
30229 It is necessary to mark this entity as a variable, in addition to
30230 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30231 modified to avoid checking the Aliased flag on entities that are not
30232 objects. (Checking that flag for non-objects is erroneous and could
30233 lead to a compiler crash).
30234
302352004-10-26 Robert Dewar <dewar@gnat.com>
30236
30237 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30238 X_Frac = 0.5, then we know that the number X must be positive.
30239 (Succ): Remove the same redundant test, and also fix the primary test
30240 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30241 Minor reformatting
30242 (Decompose): Add fuller comments to spec
30243
302442004-10-26 Pascal Obry <obry@gnat.com>
30245
30246 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30247 validity (process must have read access). Set to 0 in all other cases.
30248 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30249 violation on Win32.
30250 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30251 segmentation violation.

30257 unconstrained nominal subtype, convert the actual to the constructed
30258 subtype before taking its address.

30276 memory pools provided as part of the GNAT library.
30277 Remove "virtual" from declaration of A::method2 in
30278 the simple example of Ada/C++ mixed system.
30279 Library Projects may be virtually extended: their virtual extensions
30280 are not Library Projects.

30882 the corresponding assignment statement in the init proc.
30883 As a side effect, in the case of a derived record type, we now see the
30884 original expression, without any rewriting that could have occurred
30885 during expansion of the ancestor type's init proc, and we do not need

31828 generated name for string variable, to avoid spurious conflicts with
31829 the name of the type of a single protected object.

31839 might not be analyzed yet, even if its Etype is already set (case of an

331172004-06-07 Thomas Quinot <quinot@act-europe.fr>
33118
33119 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
33120 the index of the last element is Units.Last, not Units.Table'Last
33121 (which is usually not a valid index within the actually allocated
33122 storage for the table).
33123
33124 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
33125 determines whether to generate a call to a checked storage pool

33154
33155 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33156 includes case of a variable referenced on the left hand side of an
33157 assignment, therefore remove redundant code. Variables and prefixes of
33158 indexed or selected components are now marked as referenced on left
33159 hand side. Warnings are now properly emitted when variables or prefixes
33160 are assigned but not read.
33161
33162 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33163 left hand side referenced variables. Private access types do not
33164 produce the warning "variable ... is assigned but never read".
33165 Add also additional checks to left hand side referenced variables.
33166 Aliased, renamed objects and access types do not produce the warning
33167 "variable ... is assigned but never read" since other entities may read
33168 the memory location.

33183 distinct from the operator appearing in the source, call appropriate
33184 routine to insert conversions when needed, and complete resolution of
33185 node.
33186 (Resolve_Intrinsic_Operator): Fix cut-and-paste bug on transfer of
33187 interpretations for rewritten right operand.
33188 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33256 * sem_ch12.adb (Same_Instantiated_Constant): New name for
33257 Same_Instantiated_Entity.
33258 (Same_Instantiated_Variable): Subsidiary to

33260 formals that are obtained from a previous formal package.
33261 (Instantiate_Subprogram_Body): Emit proper error when
33262 generating code and the proper body of a stub is missing.
33263
33264 * sem_ch4.adb (Remove_Address_Interpretations): If the operation still
33265 has a universal interpretation, do the disambiguation here.
33266
33267 * exp_ch4.adb (Expand_N_Type_Conversion,
33268 Expand_N_Unchecked_Type_Conversion): Special handling when target type
33269 is Address, to avoid typing anomalies when Address is a visible integer
33270 type.
33271
33272 * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
33273 to determine whether a subprogram should not be marked Pure, even when
33274 declared in a pure package.

33283 definition found in AI-249.
33284
33285 * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when

33303 a significant reference. Warnings are now properly emitted when a
33304 discriminated type is not referenced.
33305
33306 * lib-xref.adb (Generate_Reference): A deferred constant completion,
33307 record representation clause or record type discriminant does not
33308 produce a reference to its corresponding entity. Warnings are now

33337 arguments X with a maximum relative error of T'Machine_Epsilon, for X
33338 in -2.0**32 .. 2.0**32.
33339 (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
33340 reduction by the processor, which only uses a 68-bit approximation of
33341 Pi.
33342 (Tan): Always reduce arguments and compute function either using
33343 the processor's fptan instruction, or by dividing sin and cos as needed.

33384 (Build_Limited_Views): Replace the previous implementation of the
33385 limited view by a package entity that references the first shadow
33386 entity plus the first shadow private entity (required for limited-
33387 private-with clause)
33388 (New_Internal_Shadow_Entity): Code cleanup.
33389 (Remove_Limited_With_Clause): Update the implementation to undo the
33390 new work carried out by Build_Limited_Views.

35448
35449 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35450 initialize it to another executable name than the current one. This
35451 allows to configure paths for an executable name (gnatmake) different
35452 from the current one (gnatdist).

35456 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35457 current unit cannot be inlined if it appears in the body of a withed
35458 unit, to avoid order of elaboration problems in gigi.
35459
35460 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35461 information for protected (wrapper) operation as well, to simplify gdb
35462 use.
35463
35464 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35465 protected body, indicate that the entity for the generated spec comes
35466 from source, to ensure that references are properly generated for it.
35467 (Build_Body_To_Inline): Do not inline a function that returns a
35468 controlled type.
35469

35471 apply convention to homonyms that are declared explicitly.
35472
35473 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function

35491 in the naming scheme.

355012004-03-25 Thomas Quinot <quinot@act-europe.fr>
35502
35503 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35504 attribute reference does not denote a subtype, it can be any
35505 expression that has a classwide type, potentially after an implicit
35506 dereference. In particular, the prefix can be a view conversion for
35507 a classwide type (for which Is_Object_Reference holds), but it can
35508 also be a value conversion for an access-to-classwide type. In the
35509 latter case, there is an implicit dereference, and the original node
35510 for the prefix does not verify Is_Object_Reference.
35511
35512 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35513 conversion of a discriminant-dependent component of a mutable object
35514 is one itself.

35519 inherited, has convention C, and has unconstrained array parameters,
35520 place the corresponding warning on the derived type declaration rather
35521 than the original subprogram.
35522
35523 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35524 indication on renaming declaration, if formal has a box and actual
35525 is absent.
35526
35527 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35528 determine whether to generate an implicit or explicit reference to
35529 the renamed entity.
35530
35531 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35532 subprogram renaming comes from a defaulted formal subprogram in an
35533 instance.

35537 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35538 value expressions to ensure that calls within a component definition
35539 will be checked (since those are evaluated during the record type's
35540 elaboration).

35593
35594 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35595 full view if the subtype is created for a constrained record component;
35596 gigi has enough information to construct the record, and there is no
35597 place in the tree for the declaration.
35598
35599 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without

35951 analyze and resolve the rewritten explicit dereference so it is seen
35952 by the expander.

35957 recursively insert a check for the dereference nodes contained within
35958 the check.

367472004-02-02 Javier Miranda <miranda@gnat.com>
36748
36749 * par-ch3.adb (P_Identifier_Declarations): Give support to the Ada 0Y
36750 syntax rule for object renaming declarations.
36751 (P_Array_Type_Definition): Give support for the Ada 0Y syntax rule for
36752 component definitions.
36753
36754 * sem_ch3.adb (Analyze_Component_Declaration): Give support to access
36755 components.
36756 (Array_Type_Declaration): Give support to access components. In addition
36757 it was also modified to reflect the name of the object in anonymous
36758 array types. The old code did not take into account that it is possible
36759 to have an unconstrained anonymous array with an initial value.
36760 (Check_Or_Process_Discriminants): Allow access discriminant in
36761 non-limited types.
36762 (Process_Discriminants): Allow access discriminant in non-limited types
36763 Initialize the new Access_Definition field in N_Object_Renaming_Decl
36764 node. Change Ada0Y to Ada 0Y in comments
36765
36766 * sem_ch4.adb (Find_Equality_Types): Allow anonymous access types in
36767 equality operators.
36768 Change Ada0Y to Ada 0Y in comments

36770 * sem_ch8.adb (Analyze_Object_Renaming): Give support to access
36771 renamings Change Ada0Y to Ada 0Y in comments
36772
36773 * sem_type.adb (Find_Unique_Type): Give support to the equality
36774 operators for universal access types
36775 Change Ada0Y to Ada 0Y in comments
36776
36777 * sinfo.adb (Access_Definition, Set_Access_Definition): New subprograms
36778
36779 * sinfo.ads (N_Component_Definition): Addition of Access_Definition
36780 field.
36781 (N_Object_Renaming_Declaration): Addition of Access_Definition field
36782 Change Ada0Y to Ada 0Y in comments
36783
36784 * sprint.adb (Sprint_Node_Actual): Give support to the new syntax for
36785 component definition and object renaming nodes
36786 Change Ada0Y to Ada 0Y in comments
36787
367882004-02-02 Jose Ruiz <ruiz@act-europe.fr>
36789
36790 * restrict.adb: Use the new restriction identifier
36791 No_Requeue_Statements instead of the old No_Requeue for defining the
36792 restricted profile.
36793
36794 * sem_ch9.adb (Analyze_Requeue): Check the new restriction
36795 No_Requeue_Statements.
36796
36797 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)
36798 that supersedes the GNAT specific restriction No_Requeue. The later is
36799 kept for backward compatibility.
36800
368012004-02-02 Ed Schonberg <schonberg@gnat.com>
36802
36803 * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,
36804 5staprop.adb, atree.adb, atree.ads, g-crc32.ads: Remove redundant
36805 pragma and fix incorrect ones.
36806
36807 * sem_prag.adb For pragma Inline and pragma Pure_Function, emit a
36808 warning if the pragma is redundant.
36809
368102004-02-02 Thomas Quinot <quinot@act-europe.fr>
36811
36812 * 5staprop.adb: Add missing 'constant' keywords.
36813
36814 * Makefile.in: use consistent value for SYMLIB on
36815 platforms where libaddr2line is supported.
36816
368172004-02-02 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36818
36819 * utils.c (end_subprog_body): Do not call rest_of_compilation if just
36820 annotating types.
36821
368222004-02-02 Olivier Hainque <hainque@act-europe.fr>
36823
36824 * init.c (__gnat_install_handler): Setup an alternate stack for signal
36825 handlers in the environment thread. This allows proper propagation of
36826 an exception on stack overflows in this thread even when the builtin
36827 ABI stack-checking scheme is used without support for a stack reserve
36828 region.
36829
36830 * utils.c (create_field_decl): Augment the head comment about bitfield
36831 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
36832 here, because the former is not accurate enough at this point.
36833 Let finish_record_type decide instead.
36834 Don't make a bitfield if the field is to be addressable.
36835 Always set a size for the field if the record is packed, to ensure the
36836 checks for bitfield creation are triggered.
36837 (finish_record_type): During last pass over the fields, clear
36838 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
36839 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
36840 from DECL_BIT_FIELD.

37295 processing if the type involved has non-bit-aligned components
37296
37297 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37298 N_String_Literal node always references an E_String_Literal_Subtype
37299 entity. This may not be true in the future.
37300 (Possible_Bit_Aligned_Component): Move processing of
37301 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37302
37303 * exp_ch6.adb (Expand_Thread_Body): Pick up

37342
37343 * rtsfind.adb (Load_Fail): Give full error message in configurable
37344 run-time mode if all_errors mode is set. This was not done in the case
37345 of a file not found, which was an oversight.
37346 Note if secondary stack unit is used by compiler.
37347
37348 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37349 ineffective elaborate all pragmas on non-visible packages (this
37350 happened when a renamed subprogram was called). Now the elaborate all
37351 always goes on the package containing the renaming rather than the one
37352 containing the renamed subprogram.
37353
37354 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure

37361 be true in the future.

37378 of Item_Name).
37379

37381 -B is specified. Fail when there are only foreign mains in attribute

37383 steps when -B is specified.

37400 Set_Identifier_Casing.

37403 has size that overflows.

37453 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic

37455 qualified expression. Note that qualified expressions may have to be
37456 checked when limited aggregates are implemented.
37457
37458 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37459 pure, emit warning.
37460 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37461 subprogram is imported, remove warning.

37654 are not supported. Add new formal to pass the component type (Ctype).
37655 It is required to call the corresponding IP subprogram in case of
37656 default initialized components.
37657 (Gen_Assign): In case of default-initialized component, generate a
37658 call to the IP subprogram associated with the component.

37666 default-initialized component of an aggregate.
37667 In case of default initialized aggregate with tasks this parameter is
37668 used to generate a null string (this is just a workaround that must be
37669 improved later). In case of discriminants, this parameter is used to
37670 generate a selected component node that gives access to the discriminant
37671 value.

43279 for a word. This is currently used only for CRC. In previous version,
43280 the checksum was using a representation with all letter being
43281 upper-case. With the new implementation (using CRC) we do not remove
43282 the 32th bit of the CRC, so we can have an upper-case starting letter
43283 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43284 It is ambigous since the CRC was optional and could be followed by
43285 options like EB, EE. So now this routines uses lower-case letter for
43286 the hexadecimal representation. Strange enough only lower case letters
cfac6e9f 43287 where checked in Scan_ALI (even if this was not a possible case).
