2889 Orig_Prev to Prev in the case where the actual is N_Function_Call or

2892 accessibility level, and based on testing this code is apparently no

5128 Entity and Etype to that interpretation, otherwise Entity and Etype may
5129 still refer to an interpretation that was ignored by Add_One_Interp,
5130 in which case would end up with being marked as not overloaded but with

9010 limited ancestor part, initialize controllers of enclosing record
9011 before expanding ancestor aggregate.
9012 (Gen_Assign): If a component of the aggregate is box-initialized, add
9013 code to call Initialize if the component is controlled, and explicit
9014 assignment of null if the component is an access type.
9015
9016 Handle properly aggregates for limited types that appear in object
9017 declarations when the aggregate contains controlled values such as

9034 (Make_Predefined_Primitive_Specs): Spec of "=" needed if the parent is
9035 an interface type. In case of limited interfaces we now declare all the
9036 predefined primitives associated with synchronized interfaces as
9037 abstract.
9038 (Predef_Spec_Or_Body): For interface types generate abstract subprogram
9039 declarations.
9040 (Predefined_Primitive_Bodies): Add body of "=" if the parent of the

9042 function.

9256 clauses for inherited components of a type extension.
9257 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

9495 not an entry and the context is a dispatching select. Add code to
9496 perform subtype conformance between the formals of the current entry
9497 and those of the target interface primitive.
9498 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9499 Timed_Entry_Call): Analyze the triggering statement as the first step of
9500 the processing. If this is a dispatching select, postpone the analysis
9501 of all select statements until the Expander transforms the select. This
9502 approach avoids generating duplicate identifiers after the Expander has
9503 replicated some of the select statements. In case the Expander is
9504 disabled, perform regular analysis.
9505 (Check_Triggering_Statement): New routine.
9506 (Analyze_Requeue): Exclude any interpretations that are not entries when
9507 checking overloaded names in a requeue. Also test type conformance for
9508 matching interpretations rather than requiring subtype conformance at
9509 that point to conform with the RM's resolution rule for requeues.

9e81dbc7 10474 * a-tags.adb:
68b72a44
AC		 10475 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
10476 indirection added to the HT_Link component of the TSD. This is required
10477 to statically allocate the TSD.
10478
9e81dbc7 10479 * a-tags.ads:
68b72a44
AC		 10480 Minor reordering of the declarations in the private part. Required to
10481 add a level of indirection to the contents of the TSD component HT_Link.
10482 This is required to statically allocate the TSD.
10483
10484 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
10485 Is_Statically_Allocated set from constant objects.
10486 Do not make exported constants created by the compiler volatile.

10488 as read-only.
10489
10490 * trans.c (Identifier_to_gnu): For constants, unshare initializers
10491 before returning them.
10492
10493 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
10494 public part of the package.
10495 (Make_DT): Move HT_Link component out of the TSD record. For this
10496 purpose Make_DT now declares a separate object that stores the
10497 HT_Link value, and initializes the TSD component with the address
10498 of this new object. The addition of this level of indirection is
10499 required to statically allocate the TSD because the TSD cannot
10500 have variable components.
10501 (Expand_Interface_Conversion): Improve the expanded code.
10502 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
10503
10504 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
10505 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
10506 if we are building static dispatch tables then we must not generate
10507 extra code to register the primitive because the dispatch table will
10508 be built at the end of the library package; otherwise we notify that
10509 we cannot build the static dispatch table.

10528 for thunks associated with interface types.
10529
10530 * einfo.ads: Improve documentatation of Is_Internal
10531 (Is_Thunk): New attribute applicable to subprograms. True for thunks
10532 associated with interface types.
10533 Extensive comment fixes regarding flags that appear in all entities. The
10534 documentation is now consistent for all such flags (there were a number
10535 of errors in the documentation in this regard).
10536
10537 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.

10539 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
10540 of these procedures are passed a function call that already has
10541 build-in-place actuals (testing new flag
10542 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
10543 the case where processing continues.

10545 propagate the extra actuals associated with the accessibility
10546 level of the access type actuals.
10547
10548 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
10549 of each extra formal of a protected operation to reference the

10551 operation's Protected_Body_Subprogram.
9e81dbc7 10552

10571 initialization of a full view. This is moved to
10572 Analyze_Package_Specification.
10573
10574 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10575 preelaborable initialization of a full view in entity loop.
10576 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10577 its child units are use-visible only if they are visible child units.
10578
10579 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10580 whether an expression can be used within a type declaration that
10581 requires preelaborable init.
10582 (Check_Components): Replace inline code that does partial checking for
10583 preelaborable default expressions with call to
10584 Is_Preelaborable_Expression.
10585 (Has_Preelaborable_Initialization): In the case of a generic actual
10586 subtype, (that is, Is_Generic_Actual is True), return the result of
10587 applying Has_Preelaborable_Initialization to the generic actual's base
10588 type.

10594 (Is_Leap): Move the routine to the scope of Week_In_Year.
10595 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10596 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10597 avoids calling Time_Of and Split, thus making it more efficent.
10598 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10599
10600 * g-calend.ads (Week_In_Year): Change comment to reflect new
10601 implementation.

10604
10605 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10606 Command_Line): New types
10607 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10608 support for defining how switches can be grouped on a command line (as
10609 is the case for -gnatw... for GNAT), and how simple switches can be
10610 used as aliases for more complex switches (-gnatwa is same as
10611 -gnatwbcef...)
10612 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10613 (Start, Current_*): New subprograms
10614 Added support for parsing an array of strings in addition to the real
10615 command line.
10616 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10617 be moved from the body to the private part of the spec.
10618 (*): All subprograms now have an extra parameter with default value to
10619 specify which parser should be used. For backward compatibility, it
10620 defaults to parsing the command line of the application. They were also
10621 modified to properly handle cases where each of the argument does not
10622 start at index 1 (which is always true for Ada.Command_Line, but not
10623 when processing any Argument_List).
10624 (Free): New subprogram
10625 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10626 Argument): New subprograms
10627 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10628 special characters like ':', '=',... are now handled in a single place,
10629 which makes the code more extensible eventually.
10630 (Getopt, Full_Switch): When the switch was returned as part of the
10631 special character '*', make sure it is prepended by the switch character
10632 ('-' in general), so that the application knows whether "foo" or "-foo"
10633 was specified on the command line.
10634
106352007-09-26 Florian Villoing <villoing@adacore.com>
10636
10637 * g-dirope.adb (Remove_Dir): In case we are removing directories
10638 recursively, make sure that if an exception is raised during the
10639 processing, the current working directory is reset to its initial
10640 value before propagating the exception.
10641
106422007-09-26 Vincent Celier <celier@adacore.com>
10643
10644 * gnatbind.adb: If there are several ALI files specified and there is
10645 a main program to bind, the first ALI is expected to contain the main
10646 subprogram and the names of the binder generated files will be derived
10647 from the first ALI file name.
10648 (Gnatbind): Fix insertion character in invocation of Error_Msg
10649
106502007-09-26 Vincent Celier <celier@adacore.com>

10686 packages Compiler and Binder.
10687
10688 * prj-nmsc.adb: Major rewrite of the processing of configuration
10689 attributes for gprbuild. No impact on GNAT tools.

10694 being extended, instead of a shallow copy.
10695 (Process_Project_Tree_Phase_1): New procedure
10696 (Process_Project_Tree_Phase_1): New procedure
10697 (Process): Implementation now uses the two new procedures
10698

10724
10725 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
10726 ancestor of the derived type, the operations are inherited from the
10727 primary dispatch table of the parent.
10728 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
10729 when the context is an explicit type conversion.

11028 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
11029 create an abstract subprogram in the case of 'Input. For 'Output we now
11030 create a real spec/body when the type is abstract, since it can
11031 potentially be called.
11032 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
11033 body for 'Output when the type is abstract (only the creation of the
11034 body for 'Input is excluded when the type is abstract).
11035 (Stream_Operation_OK): Add an additional condition in the return
11036 statement, so that False will be returned for TTS_Stream_Input if the
11037 associated tagged type is an abstract extension. Add comments for
11038 return statement.
11039 (Expand_N_Object_Declaration): For the case of a shared passive
11040 variable, insert init proc call only after the shared variable
11041 procedures have been processed, because the IP call needs to undergo
11042 shared passive variable reference expansion, which requires these
11043 procedures to be available (and elaborated).

11059 to remove other spurious ambiguities on arithmetic operations involving
11060 literals and addresses, on systems where Address is a visible integer
11061 type, when the operator is called in functional notation.
11062 (Try_Primitive_Operation): Within an instance, a call in prefixed form
11063 is legal when the types match, even if the operation is currently
11064 hidden.

11422 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined

11424 build-in-place functions (such as stream 'Input).

11510
11511 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
11512 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11513 the statement which is being resolved comes from a predefined library
11514 unit, all non-predefined library interpretations are skipped.
11515 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11516 but the "&" is user defined, give an error, because the folding would
11517 be wrong.
11518
11519 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
11520 the parser has folded a long sequence of concatenations of string
11521 literals.

11524 and "JMP_BUF" variables as artificial.
11525 (N_String_Literal): Do not use alloca for very long string literals. Use
11526 xmalloc/free instead. Otherwise the stack might overflow.

ab6328d0
AC		 11574 Suppress unmodified in-out parameter warning in some cases
11575 This patch is a also fairly significant change to the way suppressible
11576 checks are handled.
11577
11578 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
11579 needed for access to concurrent record types generated by the expander.
11580 (Generate_Range_Check): When generating a temporary to capture the
11581 value of a conversion that requires a range check, set the type of the
11582 temporary before rewriting the node, so that the type is always
11583 properly placed for back-end use.
11584 (Apply_Float_Conversion_Check): Handle case where the conversion is
11585 truncating.
11586 (Get_Discriminal): Code reformatting. Climb the scope stack looking
11587 for a protected type in order to examine its discriminants.

11598 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
11599 (Get_Allocator_Final_List): For the case of an anonymous access type
11600 that has a specified Associated_Final_Chain, do not go up to the
11601 enclosing scope.
11602 (Expand_N_Type_Conversion): Test for the case of renamings of access
11603 parameters when deciding whether to apply a run-time accessibility
11604 check.
11605 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11606 aggregate code before allocator, and ahead of declaration for
11607 temporary, to prevent access before elaboration when the allocator is
11608 an actual for an access parameter.
11609 (Expand_N_Type_Conversion): On an access type conversion involving an
11610 access parameter, do not apply an accessibility check when the
11611 operand's original node was an attribute other than 'Access. We now
11612 create access conversions for the expansion of 'Unchecked_Access and
11613 'Unrestricted_Access in certain cases and clearly accessibility should
11614 not be checked for those.
11615
11616 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11617 includes a type conversion of a packed component that has been expanded,
11618 recover the original expression for the object, and use this expression
11619 in the post-call assignment statement, so that the assignment is made
11620 to the object and not to a back-end temporary.
11621 (Freeze_Subprogram): In case of primitives of tagged types not defined
11622 at the library level force generation of code to register the primitive
11623 in the dispatch table. In addition some code reorganization has been
11624 done to leave the implementation clear.
11625 (Expand_Call): When expanding an inherited implicit conversion,
11626 preserve the type of the inherited function after the intrinsic
11627 operation has been expanded.
11628
11629 * exp_ch2.ads, exp_ch2.adb
11630 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11631 of an entry formal appearing in an assignment statement does not assign
11632 to the formal.
11633 (Expand_Current_Value): Instead of calling a routine to determine
11634 whether the prefix of an attribute reference should be optimized or
11635 not, prevent the optimization of such prefixes all together.
11636
11637 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11638 component whose prefix is known to be of an access type is an implicit
11639 dereference and does not assign to the prefix.

11646 new itype.
11647 Add comments and correct harmless error in Build_NCT_Hash_Tables
11648 (Array_Aggr_Subtype): Associate each itype created for an index type to
11649 the corresponding range construct, and not to the aggregate itself. to
11650 maintain a one-to-one correspondence between itype and its associated
11651 node, to prevent errors when complex expression is copied.
11652 Fix mishandling of multiple levels of parens
11653
11654 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11655 treatment of limited views uniform for all visible declarations in a
11656 limited_withed package.
11657 (New_Copy_Tree): If hash table is being used and itype is visited,
11658 make an entry into table to link associated node and new itype.
11659 (Resolve_Record_Aggregate): Do not add an others box association for a
11660 discriminated record component that has only discriminants, when there
11661 is a box association for the component itself.
11662

11708 Warn on duplicate pragma Preelaborable_Initialialization
11709
11710 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11711 generation of a freezing node to ensure proper management of null
11712 excluding access types in the backend.
11713 (Create_Extra_Formals): Test base type of the formal when checking for
11714 the need to add an extra accessibility-level formal. Pass the entity E
11715 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11716 originally being done in a couple of cases), to ensure that the
11717 Extra_Formals list gets set on the entity E when the first entity is
11718 added.
11719 (Conforming_Types): Add missing calls to Base_Type to the code that
11720 handles anonymous access types. This is required to handle the
11721 general case because Process_Formals builds internal subtype entities
11722 to handle null-excluding access types.
11723 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11724 functions that need it, even when not marked Requires_Overriding.
11725 Improve warnings for in out parameters
11726 (Analyze_Function_Return): Warn for disallowed null return
11727 Warn on return from procedure with unset out parameter
11728 Ensure consistent use of # in error messages
11729 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11730 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11731 the implicit conversion of the expression done for anonymous access
11732 types. This is required to generate the code of the null excluding
11733 check (if required).
11734
11735 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11736 A formal parameter is never publicly referenceable outside of its body.
11737 (Check_References): For an unreferenced formal parameter in an accept
11738 statement, use the same warning circuitry as for subprogram formal
11739 parameters.
11740 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11741 Output_Unreferenced_Messages, containing the part of that routine that
11742 is now reused for entry formals as described above.
11743 (Goto_Spec_Entity): New function
11744 (Check_References): Do not give IN OUT warning for dispatching operation
11745 Improve warnings for in out parameters
11746 (Test_Ref): Check that the entity is not undefinite before calling
11747 Scope_Within, in order to avoid infinite loops.

11754
11755 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11756 (Expand_N_Attribute_Reference): Further unify the handling of the
11757 three forms of access attributes, using common code now for all three
11758 cases. Add a test for the case of applying an access attribute to
11759 an explicit dereference when the context is an access-to-interface
11760 type. In that case we need to apply the conversion to the prefix
11761 of the explicit dereference rather than the prefix of the attribute.
11762 (Attribute_Version, UET_Address): Set entity as internal to ensure
11763 proper dg output of implicit importation.
11764 (Expand_Access_To_Type): Removed.
11765 (Expand_N_Attribute_Reference): Merge the code from the three cases
11766 of access attributes, since the processing is largely identical for
11767 these cases. The substantive fix here is to process the case of a
11768 type name prefix (current instance case) before handling the case
11769 of interface prefixes.

11777 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11778 type that is an anonymous access to controlled object, establish
11779 an associated finalization chain to avoid corrupting the global
11780 finalization list when a dynamically allocated object designated
11781 by such a component is deallocated.
11782 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11783 functions that need it, even when not marked Requires_Overriding.
11784 (Initialize_Tag): Replace call to has_discriminants by call to
11785 Is_Variable_Size_Record in the circuitry that handles the
11786 initialization of secondary tags.
11787 (Is_Variable_Size_Record): New implementation.
11788 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11789 Suppress_Initialization pragma for a derived type.
11790 (Is_Variable_Size_Record): New subprogram.
11791 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11792 initial version of this routine and also fixes problems causing
11793 incomplete initialization of the table of interfaces.
11794 (Build_Init_Procedure): Improve the generation of code to initialize the
11795 the tag components of secondary dispatch tables.
11796 (Init_Secondary_Tags): New implementation that simplifies the previous
11797 version of this routine.
11798 (Make_DT): Add parameter to indicate when type has been frozen by an
11799 object declaration, for diagnostic purposes.
11800 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11801 diagnose attemps to freeze a subprogram when some untagged type of its
11802 profile is a private type whose full view has not been analyzed yet.
11803 (Freeze_Array_Type): Generate init proc for packed array if either
11804 Initialize or Normalize_Scalars is set.
11805 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11806 constructing the new profile, copy the null_exclusion indicator for each
11807 parameter, to ensure full conformance of the new body with the spec.
11808
11809 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11810 Create wrappers for constructor functions that need it, even when not
11811 marked Requires_Overriding.
11812 (Covers): Handle properly designated types of anonymous access types,
11813 whose non-limited views are themselves incomplete types.
11814 (Add_Entry): Use an entity to store the abstract operation which hides
11815 an interpretation.
11816 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11817 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11818 initialization aggregate.
11819 (Function_Interp_May_Be_Hidden): Rename to
11820 Function_Interp_Has_Abstract_Op.
11821 (Has_Compatible_Type): Remove machinery that skips interpretations if
11822 they are labeled as potentially hidden by an abstract operator.
11823 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11824 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11825 (Write_Overloads): Output the abstract operator if present.
11826 (Add_Entry): Before inserting a new entry into the interpretation table
11827 for a node, determine whether the entry will be disabled by an abstract
11828 operator.
11829 (Binary_Op_Interp_May_Be_Hidden): New routine.
11830 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11831 aggregate.
11832 (Function_Interp_May_Be_Hidden): New routine.
11833 (Has_Compatible_Type): Do not consider interpretations hidden by
11834 abstract operators when trying to determine whether two types are
11835 compatible.
11836 (Has_Hidden_Interp): New routine.
11837 (Set_May_Be_Hidden_Interp): New routine.

11844 types declared in the declarative part of a nested package body or in
11845 the proper body of a stub.
11846 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11847 of the same dispatch table slot to renamed primitives.
11848 (Make_Select_Specific_Data_Table): Handle private types.
11849 (Tagged_Kind): Handle private types.
11850 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11851 output of implicit importation and exportation.
11852 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11853 first formal of the thunk is always associated with the controlling
11854 type. In addition perform the following code cleanup: remove formal
11855 Thunk_Alias which is no longer required, cleanup evaluation of the
11856 the controlling type, and update the documentation.
11857 Replace occurrence of Default_Prim_Op_Count by
11858 Max_Predef_Prims. Addition of compile-time check to verify
11859 that the value of Max_Predef_Prims is correct.
11860 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11861 (Make_DT): Add parameter to indicate when type has been frozen by an
11862 object declaration, for diagnostic purposes.
11863 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11864 construction of statically allocated dispatch tables.
11865 (Make_DT): In case of library-level tagged types export the declaration
11866 of the primary tag. Remove generation of tags (now done by Make_Tags).
11867 Additional modifications to handle non-static generation of dispatch
11868 tables. Take care of building tables for asynchronous interface types
11869 (Make_Tags): New subprogram that generates the entities associated with
11870 the primary and secondary tags of Typ and fills the contents of Access_
11871 Disp_Table. In case of library-level tagged types imports the forward
11872 declaration of the primary tag that will be declared later by Make_DT.
11873 (Expand_Interface_Conversion): In case of access types to interfaces
11874 replace an itype declaration by an explicit type declaration to avoid
11875 problems associated with the scope of such itype in transient blocks.

11880
9e81dbc7 11881 * exp_util.ads, exp_util.adb:
ab6328d0
AC		 11882 This patch replaces a number of occurrences of explicit tests for N_Null
11883 with calls to Known_Null. This improves tracking of null values, since
11884 Known_Null also catches null constants, and variables currently known to
11885 be null, so we get better tracking.
11886 (Ensure_Defined): create an itype reference only in the scope of the
11887 itype.
11888 (Side_Effect_Free): A selected component of an access type that
11889 denotes a component with a rep clause must be treated as not

12365 generated spec.
12366 (Analyze_Compilation_Unit): If unit is a subprogram body that has no
12367 separate declaration, remove the unit name from visibility after
12368 compilation, so that environment is clean for subsequent compilations.
12369 (Install_Limited_Context_Clauses): Do not install a

12537 of Set_Item.
12538 (Set_Item): When the new item is an element of the currently allocated
12539 table passed by reference, save a copy on the stack if we're going
12540 to reallocate. Also, in Table.Set_Item, make sure we test the proper
12541 variable to determine whether to call Set_Last.

12556 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
12557 derived type with interface progenitors use the analyzed formal as the
12558 parent of the actual, to create renamings for all the inherited
12559 operations in Derive_Subprograms.
12560 (Collect_Previous_Instances): new procedure within of
12561 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12562 unit being loaded, to ensure that the generation of global symbols is
12563 consistent in different compilation modes.
12564 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12565 takes progenitor types into account.
12566 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12567 traversing over the primitives of the formal and actual types to locate
12568 any abstract subprograms of the actual type that correspond to a
12569 nonabstract subprogram of the formal type's ancestor type(s), and issue
12570 an error if such is found.
12571 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12572 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12573 Remove bogus guard around calls to Inherit_Context.
12574 (Reset_Entity): If the entity is the selector of a selected component
12575 that denotes a named number, propagate constant-folding to the generic
12576 template only if the named number is global to the generic unit.
12577 (Set_Instance_Env): Only reset the compilation switches when compiling
12578 a predefined or internal unit.

12582 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
12583 parameter to determine whether operation applies to the prefix.
12584 (Complete_Object_Operation): If actual has an access type and
12585 controlling formal is not an in_parameter, reject the actual if it is
12586 an access_to_constant type.
12587 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12588 type, the candidate operations are found in the scope of declaration of
12589 the type, because the type has no primitive subprograms.
12590 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12591 a private extension, only examine visible components before trying to
12592 analyze as a prefixed call.
12593 Change Entity_List to Type_To_Use, for better readability.
12594 (Has_Fixed_Op): Use base type when checking whether the type of an

12603 formal At_Any_Place indicating, when True, that we want to test for
12604 availability of the stream attribute at any place (as opposed to the
12605 current visibility context only).
12606 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12607 purpose of enforcing E.2.2(8) only if it is not available at any place.
12608 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12609 when checking the legality of an extension aggregate in a preelaborable
12610 package. Treat the literal null as a valid default expression in a
12611 component declaration for a type with preelaborable initialization.
12612 A limited interface is a legal progenitor for the designated type of a
12613 remote access to class-wide type.

12625 mark the full view as referenced, to prevent spurious warnings.
12626 (Find_Selected_Component, Has_Components): Handle properly non-limited
12627 views that are themselves incomplete types.
12628 Handle interfaces visible through limited-with clauses.
12629 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12630 subprogram generic actual for which we have generated a renaming.
12631 Warn when the renaming introduces a homonym of

12641 the allocator is not a coextension.
12642 (Resolve): Skip an interpretation hidden by an abstract operator only
12643 when the type of the interpretation matches that of the context.
12644 (Resolve): When looping through all possible interpretations of a node,
12645 do not consider those that are hidden by abstract operators.
12646 (Resolve_Actuals): When verifying that an access to class-wide object
12647 is an actual for a controlling formal, ignore anonymous access to
12648 subprograms whose return type is an access to class_wide type.
12649 (Resolve_Slice): If the prefix of the slice is a selected component
12650 whose type depends on discriminants, build its actual subtype before
12651 applying range checks on the bounds of the slice.
12652 (Valid_Conversion): In an instance or inlined body, compare root types,
12653 to prevent anomalies between private and public views.
12654 (Resolve): Improve error message for ambiguous fixed multiplication
12655 expressions that involve universal_fixed multiplying operations.

12675 elabration statements, register the package with the name server
12676 at the beginning, not at the end, of the elaboration statements so
12677 that they can create remote access to subprogram values that designate

13834 Remove the pragma Thread_Body, and the associated flag
13835 Is_Thread_Body in entities, and all related code.
13836 (Suppress_Value_Tracking_On_Call): New flag
13837 E_Exception has Esize and Alignment fields
13838 (Universal_Aliasing): New function.
13839 (Set_Universal_Aliasing): New procedure.
13840 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
13841 (Check_Nested_Access): New procedure.
13842 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
13843 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13844 (Related_Interface): New attribute. Present in dispatch table pointer
13845 components of records. Set to point to the entity of the corresponding
13846 interface type.
13847 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13848 (Original_Access_Type): Remove, not needed.
13849 (Root_Type): Handle properly subtypes of class-wide-types.
13850 Update comments.
13851
13852 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13853 class-wide types visible through limited-with clauses.
13854 (Try_Primitive_Operation): When examining all primitive operations of a
13855 tagged type, do not consider subprograms labeled as hidden unless they
13856 belong to a private generic type with a tagged parent.
13857 (Try_Object_Operation): Extensive rewriting, to handle properly various
13858 overloading cases, when several ancestors may have class-wide operations
13859 that are possible candidates, and when the overloaded functions return
13860 array types and have defaulted parameters so that the call may be
13861 interpreted as an indexing.
13862 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13863 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13864 successive actuals before analyzing the call itself.
13865 (Try_Primitive_Operation): A primitive operation is compatible with the
13866 prefix if the prefix has a synchronized type and the type of the formal
13867 is its corresponding record, as can be the case when the primitive
13868 operation is declared outside of the body of the type.
13869 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13870 perform homonym traversal, looking for class-wide operation matches
13871 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13872 access parameters are now restricted to anonymous access types.
13873 (Mark_Allocator): An allocator with a discriminant association parent is
13874 a coextension.
13875 (Try_One_Prefix_Interpretation): If the type of the object is
13876 incomplete, as can be happen when it is a limited view obtained through
13877 a limited_with_clause, the selected component is not part of a prefixed
13878 call.
13879 (Complete_Object_Operation): Diagnose properly an object that is not
13880 aliased when the corresponding controlling formal is an access
13881 parameter.
13882 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13883 ambiguous calls in prefixed notation, where two primitives differ only
13884 in that the controlling argument of one is an access parameter.
13885
13886 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13887 whether a function that returns an unconstrained type can be inlined.
13888 (Process_Formals): Diagnose properly the illegal use of an incomplete
13889 type in the profile of an access_to_subprogram declaration.
13890 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13891 operations are attached to the corresponding record.
13892 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13893 When processing a primitive of a concurrent type which implements an
13894 interface change the type of all controlling formals to that of the
13895 corresponding record type.
13896 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13897 to determine the tagged type to which a primitive belongs.
13898 (Check_Conventions): Capture condition to ignore a primitive operation
13899 (which is shared between the loop in Check_Conventions and the one in
13900 Check_Convention) in a new local function Skip_Check.
13901 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13902 confusion with Check_Conventions' own Prim_Op local variable.
13903 (Create_Extra_Formals): Test for a tagged result type rather than a
13904 controlling result when determining whether to add a BIP_Alloc_Form
13905 formal and a BIP_Final_List formal to the function.
13906 (Check_Conformance); For parameters that are anonymous access types,
13907 subtype conformance requires that the not null and the constant
13908 indicators must match
13909 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13910 to retrieve the appropriate type when processing a concurrent type
13911 declared within a generic. Minor comment reformatting. Change invocation
13912 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13913 mitive.
13914 (Analyze_Subprogram_Body): If the return type of a function is an
13915 anonymous access to the limited view of a class-wide type, and the
13916 non-limited view of the type is available, update the type of the
13917 function so that code can be generated.
13918 (Process_Formals): In case of access-subtype itype whose designated
13919 type is also an itype (situation that happens now with access to
13920 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13921 attribute to avoid backend problems.
13922 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13923 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13924 anonymous types' designated types are same before testing
13925 Subtypes_Statically_Match.
13926 (Create_Extra_Formals): Test for a named access parameter that is a
13927 controlling formal as an additional condition for adding an
13928 accessibility level formal. This can occur in the subp type created for
13929 dispatching calls in Expand_Dispatching_Call, and allows calling
13930 Create_Extra_Formals from that procedure rather than special-casing the
13931 extra formals there.
13932 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13933 when the function has a controlling result.
13934 (Check_Returns): Add much more knowledge of the optimization of local
13935 raise statements to gotos, to retain proper warnings in this case.
13936 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13937 nodes when looking for last statement.
13938
13939 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13940 class-wide types visible through limited with clauses.
13941 (Add_One_Interp): If the operands are anonymous access types, the
13942 predefined operator on universal_access is immediately visibles
13943 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13944 other anonymous access types.
13945 (Disambiguate): Take into account CIL convention.
13946 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13947
139482007-06-06 Robert Dewar <dewar@adacore.com>
13949
13950 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13951 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13952 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13953 Fix lower bound of tables.
13954 Add rep clauses.
13955
13956 * nlists.adb: Ditto.
13957 (Prev_Node, Next_Node): Change index type to Int so that it properly
13958 covers the range First_Node_Id - 1 up.

13964
9e81dbc7 13965 * exp_aggr.ads, exp_aggr.adb:
ec11296f
AC		 13966 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13967 in extension aggregates.
13968 (Flatten): Other conditions being met, an aggregate is static if the
13969 low bound given by component associations is different from the low
13970 bound of the base index type.
13971 (Packed_Array_Aggregate_Handled): If the component type is itself a
13972 packed array or record, the front-end must expand into assignments.
13973 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13974 Init_Pr, instead of Ancestor_Is_Expression.
13975 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13976 coextension chain root, either generate a list controller or use the
13977 already existing one.
13978 (Static_Array_Aggregate): New procedure to construct a positional
13979 aggregate that can be handled by the backend, when all bounds and
13980 components are compile-time known constants.
13981 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13982 types covering interface types into assignments.
13983 (Replace_Type): move to Build_Record_Aggr_Code.
13984 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13985 interface type, convert to the definite type of the aggregate itself,
13986 so that needed components are visible.
13987 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13988 components and the context is an extended return statement do not
13989 create a transient block for it, to prevent premature finalization
13990 before the return is executed.
13991 (Gen_Assign): Do not generate a call to deep adjust routine if the
13992 component type is itself an array of controlled (sub)-components
13993 initialized with an inner aggregate.
13994 (Component_Check): New name for Static_Check. This name is now more
13995 appropriate, and documentation is added which was missing.
13996 (Component_Check): Add test for bit aligned component value
13997 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13998 Tagged_Comps, name is more appropriate given added function below.
13999 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

14002 Javier Miranda <miranda@adacore.com>
14003 Robert Dewar <dewar@adacore.com>
14004
14005 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
14006 Terminated: Add unchecked type conversion from System.Address to
14007 System.Tasking.Task_Id when calling the predefined primitive
14008 _disp_get_task_id.
14009 Disable new Ada 05 accessibility check for JVM.NET targets, which
14010 cannot be implemented in a practical way.
14011 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
14012 the sources always references the tag of the actual object. Therefore,
14013 if 'Tag is applied in the sources to class-wide interface objects we
14014 generate code that displaces "this" to reference the base of the object.
14015 (Expand_N_Attribute_Reference, case Size): Return specified size if
14016 known to front end.
14017 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
14018 has code that displaces the pointer of the object to manage interface
14019 types. However this code must not be executed when the prefix is a
14020 subprogram. This bug caused the wrong expansion of the internally
14021 generated assignment that fills the dispatch table when the primitive
14022 is a function returning a class-wide interface type.
14023 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
14024 Set_Attribute_Name for Name_Unaligned_Valid.
14025
140262007-06-06 Ed Schonberg <schonberg@adacore.com>
14027 Gary Dismukes <dismukes@adacore.com>
14028
14029 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
14030 If the initialization is the equivalent aggregate of the initialization
14031 procedure of the type, do not remove it.
14032 (Expand_N_Attribute_Definition_Clause): Exclude access variables
14033 initialized to null from having their expression reset to empty and
14034 note this exception in the comment.
14035

14038 Ed Schonberg <schonberg@adacore.com>
14039 Gary Dismukes <dismukes@adacore.com>
14040
14041 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
14042 Add "with" and "use" clauses for Sem_Attr.
14043 (Expand_Current_Value): Do not replace occurences of attribute
14044 references where the prefix must be a simple name.
14045
14046 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
14047 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
14048 Attribute_Requires_Simple_Name_Prefix.
14049 (Name_Modifies_Prefix): Body of new function.
14050 (Requires_Simple_Name_Prefix): Body of new function.
14051 (Resolve_Attribute, case Access): Improve error message for case of
14052 mismatched conventions.
14053 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
14054 incomplete type.
14055 (Analyze_Attribute, case 'Access): If the type of the prefix is a
14056 constrained subtype for a nominal unconstrained type, use its base type
14057 to check for conformance with the context.
14058 (Resolve_Attribute): Remove test of the access type being associated
14059 with a return statement from condition for performing accessibility
14060 checks on access attributes, since this case is now captured by
14061 Is_Local_Anonymous_Access.
14062 (Analyze_Access_Attribute): Set Address_Taken on entity
14063 (Analyze_Attribute, case Address): Set Address_Taken on entity
14064 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
14065 validating an access attribute whose prefix is a current instance.
14066 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
14067 applied to dispatching operations, if freezing is required then we set
14068 the attribute Has_Delayed_Freeze in the prefix's entity.
14069 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
14070 current scope if access of local subprogram taken
14071 (Analyze_Access_Attribute): Check legality of self-reference even if the
14072 expression comes from source, as when a single component association in
14073 an aggregate has a box association.
14074 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
14075 the prefix if it is a protected operation and the attribute is
14076 Unrestricted_Access.
14077 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
14078 reference to the base type of the context, to force a constraint check
14079 when the context is an access subtype with an explicit constraint.
14080 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
14081 node is rewritten as an interface conversion. leave unanalyzed after
14082 resolution, to ensure that type checking against the context will take
14083 place.
14084

14087 Robert Dewar <dewar@adacore.com>
14088
14089 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
14090 wrapper when the full view of the controlling type of an inherited
14091 function that dispatches on result implements interfaces.
14092 (Expand_N_Object_Declaration): In cases where the type of the
14093 declaration is anonymous access, create finalization list for it.
14094 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
14095 if the object has no explicit initialization, to match description of
14096 functionality of pragam Persistent_BSS.
14097 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
14098 new function to build static aggregates, to replace initialization call
14099 when static initialization is desired.
14100 (Freeze_Type): Generate a list controller for an access type whenever
14101 its designated type has controlled anonymous access discriminants.
14102 (Build_Equivalent_Aggregate): New procedure to compute a static
14103 aggregate to be used as default initialization for composite types,
14104 instead of a generating a call to the initialization procedure for the
14105 type.
14106 (Build_Initialization_Call): When available, replace a call to the
14107 initialization procedure with a copy of the equivalent static aggregate
14108 for the type.
14109 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
14110 declarations for objects of a class-wide interface type, rather than
14111 just identifiers, to prevent visibility problems.
14112 (Expand_N_Object_Declaration): When expanding the declaration for an
14113 object of a class-wide interface type, preserve the homonym chain of
14114 the original entity before exchanging it with that of the generated
14115 renaming declaration.
14116 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
14117 active, because there is no way to handle the exception.
14118 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
14119 to do a minimum decoration of the Access_Disp_Table list.
14120 (Expand_Record_Controller): Avoid the addition of the controller between
14121 the component containing the tag of a secondary dispatch table and its
14122 adjacent component that stores the offset to the base of the object.
14123 This latter component is only generated when the parent type has
14124 discriminants ---documented in Add_Interface_Tag_Components).
14125 (Apply_Array_Size_Check): Removed, no longer needed.
14126 (Expand_N_Full_Type_Declaration): If the type has anonymous access
14127 components, create a Master_Entity for it only if it contains tasks.
14128 (Build_Init_Procedure): Suppress the tag assignment compiling under
14129 no run-time mode.
14130 (Freeze_Record_Type): Remove code associated with creation of dispatch
14131 table.
14132 (Init_Secondary_Tags): Update type of actuals when generating calls to
14133 Ada.Tags.Set_Offset_To_Top
14134 (Stream_Operation_OK): Disable use of streams compiling under no
14135 run-time mode
14136 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
14137 if Has_Init_Expression set.
14138 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
14139 Register_Primitive, which provides the same functionality.
14140 (Requires_Init_Proc): Return false in case of interface types.
14141 (Add_Secondary_Tables): Use the new attribute Related_Interface to
14142 cleanup the code.
14143 (Predefined_Primitive_Freeze): Do not assume that an internal entity
14144 is always associated with a predefined primitive because the internal
14145 entities associated with interface types are not predefined primitives.
14146 Therefore, the call to Is_Internal is replaced by a call to the
14147 function Is_Predefined_Dispatching_Operation.
14148 (Make_Eq_If): When generating the list of comparisons for the
14149 components of a given variant, omit the controller component that is
14150 present if the variant has controlled components.

14154 Bob Duff <duff@adacore.com>
14155
14156 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
14157 handle the creation of finalization lists and calls for nested
14158 coextensions when the root of the chains is part of a return statement.
14159 (Inside_A_Return_Statement): New function inside Complete_Coextension_
14160 Finalization.
14161 (Expand_Record_Equality): Skip components that are interface types.
14162 (Displace_Allocator_Pointer): Add missing support for interface subtypes
14163 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
14164 with Rewrite_Coextension. Change the condition for detecting coextension
14165 root nodes.
14166 (Is_Local_Access_Discriminant): Removed.
14167 (Rewrite_Coextension): New routine which rewrites a static coextension
14168 as a temporary and uses its unrestricted access in the construction of
14169 the outer object.
14170 (Complete_Coextension_Finalization): New routine. Generate finalization
14171 attachment calls to all delayed coextensions.
14172 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
14173 the allocator is not a coextension itself and has delayed coextensions.
14174 If the current allocator is controlled, but also a coextension, delay
14175 the generation of the finalization attachment call.
14176 Rename local variable "Node" to "Nod" in order to avoid confusion with
14177 "Elists.Node".
14178 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
14179 limited types that are not inherently limited. Such an allocator is
14180 illegal, but is generated by the expander for a return statement, to
14181 copy the result onto the secondary stack. This is the only case where a
14182 limited object can be copied. Generate code to displace the pointer
14183 to the object if the qualified expression is a class-wide interface
14184 object. Such displacement was missing and hence the copy of the object
14185 was wrong.
14186 (Apply_Accessibility_Check): Handle allocated objects initialized in
14187 place.
14188 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
14189 and Expand_Allocator_Expression. Allocating class-wide interface objects
14190 this routine displaces the pointer to the allocated object to reference
14191 the component referencing the corresponding secondary dispatch table.
14192 Expand_Allocator_Expression): Add missing support to allocate class-wide
14193 interface objects initialized with a qualified expression.
14194 (Get_Allocator_Final_List): Test for an anonymous access type that is a
14195 function result type, and use the finalization list associated with the
14196 function scope in that case (such an anonymous type should not be
14197 treated like an access parameter's type).

14202
14203 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
14204 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
14205 required exception handler.
14206 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
14207 properly the case of a function whose return type is a limited
14208 class-wide interface type. Modify the code of the accessibility
14209 check to handle class-wide interface objects. In this case we need to
14210 displace "this" to reference the primary dispatch table to get access
14211 to the TSD of the object (to evaluate its accessibility level).
14212 (Expand_N_Extended_Return_Statement): Test for a tagged result type
14213 rather than a controlling result as one of the conditions for
14214 generating tests of the implicit BIP_Alloc_Form formal. The
14215 initialization assignment is also handled according to whether the
14216 result is tagged instead of controlling.
14217 In the case where the init assignment is inserted in the "then" part of
14218 the allocation conditional, rewrite the target to be a dereference of
14219 the implicit BIP_Object_Access formal.
14220 If the returned value is unconstrained and created on the secondary
14221 stack, mark the enclosing block and function so that the secondary
14222 stack is not reclaimed on return.
14223 Treat returns from functions with controlling results similarly to
14224 returns from functions with unconstrained result subtypes.
14225 If the object returned is unconstrained, and an allocator must be
14226 created for it, analyze the allocator once the block for the extended
14227 return is installed, to ensure that finalizable components
14228 of the expression use the proper finalization list. Guard the call to
14229 Move_Final_List with a check that there is something to finalize.
14230 (Make_Tag_Ctrl_Assignment): Use "old" handling
14231 of controlled type assignment for virtual machines, since new code uses
14232 unsupported features (such as direct access to bytes in memory).

14237 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
14238 accessibility actual, check for the case of an aliased object that has
14239 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
14240 we fall into processing for the attribute rather than the name of the
14241 object.
14242 (Expand_Inline_Call): If an actual is a literal, and the corresponding
14243 formal has its address taken in the body, create a temporary to capture
14244 value. If the return type is a limited interface, do not treat the
14245 return value as Controlled.
14246 (Is_In_Place_Function): If the return type is a limited interface,
14247 treat as returning in place. The actual returned object may not always
14248 be limited, but the caller has to assume that it is returned in place.
14249 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
14250 context of an allocator, use the correct finalization chain (that is,
14251 the chain belonging to the access type, rather than the chain belonging
14252 to the current scope).
14253 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
14254 result type rather than a controlling result as a precondition for
14255 adding an allocation form actual to a build-in-place call.
14256 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
14257 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
14258 primitive in the dispatch tables. This work is now done by Make_DT when
14259 the type is frozen.
14260 (Register_Predefined_DT_Entry): Removed.
14261 (Add_Return): If end label is not present, use sloc of last statement
14262 for generated return statement in procedure, for better gdb behavior
14263 on expanded code.
14264 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
14265 object address nodes to ensure proper processing by routines like
14266 Insert_After*.
14267 (Expand_Call): Fix generation of validity check for parameter
14268 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
14269 the allocation form parameter if the result subtype is constrained,
14270 except when the function has a controlling result.
14271 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
14272 rather than Is_Controlled and Has_Controlled_Component, since we want to
14273 include class-wide result types in this treatment. Also test for a
14274 controlling result, since that also requires passing a finalization
14275 list.
14276 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
14277 even when the result subtype is constrained, to handle calls involving
14278 controlling results.
14279 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
14280 is now called even when the result subtype is constrained, to handle
14281 calls involving controlling results.
14282 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
14283 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
14284 now performs the test).
14285 (Make_Build_In_Place_Call_In_Object_Declaration):
14286 Add_Alloc_Form_Actual_* is now called even when the result subtype is
14287 constrained, to handle calls involving controlling results.
14288 (Add_Return): Accomodate rewritten pattern from local raise to goto
14289 transformation, so that we still recognize an transfer statement
14290 and do the right thing here in that case.
14291 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
14292 and end of subprogram code.
14293 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14294 support for primitives that are functions (without formals) with a
14295 controlling result.
14296 (Inherited_From_Formal): If the actual subtype has not generic parent
14297 type, it is not an actual for a formal derived type, and there is no
14298 operation to inherit from the formal.
14299
143002007-06-06 Ed Schonberg <schonberg@adacore.com>
14301 Thomas Quinot <quinot@adacore.com>
14302
14303 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
14304 inserted cleanup code appropriately for GDB use.
14305 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
14306 exception handler for Deep_Adjust or Deep_Finalize.
14307 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14308 Raise_From_Controlled_Operation is available, use a call to that
14309 subprogram instead of a plain "raise Program_Error" node to raise
14310 Program_Error if an exception is propagated from an Adjust or Finalize
14311 operation.
14312 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14313 appears in the optional statement list of a triggering alternative, the
14314 scope actions can be inserted directly there, and not in the list that
14315 includes the asynchronous select itself.
14316

14319 Hristian Kirtchev <kirtchev@adacore.com>
14320
14321 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
14322 generated exception handler appropriately when debugging generated code.
14323 Deal properly with No_Exception_Propagation restriction mode.
14324 (Expand_N_Abort_Statement): Add an unchecked type conversion from
14325 System.Address to System.Tasking.Task_Id when processing the result of
14326 the predefined primitive _disp_get_task_id.
14327 (Expand_N_Asynchronous_Select): Clarify comment.
14328 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
14329 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
14330 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
14331 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
14332 privals and for generated call to Complete_Entry_Body, for better gdb
14333 behavior.
14334 (Copy_Result_Type): Utility to construct a parameter and result profile
14335 for protected functions whose return type is an anonymous access to
14336 subprogram.
14337 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
14338 call the above.
14339 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
14340 point when the local-raise-to-goto transformation has taken place.
14341
143422007-06-06 Javier Miranda <miranda@adacore.com>
14343 Nicolas Setton <setton@adacore.com>
14344
14345 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14346 functionality when the backend is generating code.
14347 Otherwise any serious error
14348 reported by the backend calling the frontend routine Error_Msg
14349 changes the Compilation_Mode to Check_Semantics, disables the
14350 functionality of this routine and causes the generation of
14351 spureous additional errors.
14352
14353 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14354 debugging information now generated by the compiler for fat-pointer
14355 types.
14356 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
14357 DWARF2/3.
14358 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
14359
143602007-06-06 Thomas Quinot <quinot@adacore.com>
14361
14362 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
14363 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14364 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14365 For a remote call to a function with a classwide return type, apply an
14366 E.4(18) check to the returned value.
14367 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
14368 stream attributes of the designated type of an RACW, as they are not
14369 dispatching primitive operations.
14370
143712007-06-06 Geert Bosch <bosch@adacore.com>
14372
14373 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
14374 negative literal
14375 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
14376 positive
14377 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
14378 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
14379 positive
14380 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
14381
143822007-06-06 Javier Miranda <miranda@adacore.com>
14383
14384 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
14385 attribute compiling package Ada.Tags under No_Run_Time_Mode.
14386
143872007-06-06 Javier Miranda <miranda@adacore.com>
14388
14389 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14390 deallocation of class-wide interface objects.
14391 (Expand_Dispatching_Constructor_Call): Take into account that if the
14392 result of the dispatching constructor is an interface type, the
14393 function returns a class-wide interface type; otherwise the returned
14394 object would be actual. The frontend previously accepted returning
14395 interface types because Expand_Interface_Actuals silently performed
14396 the management of the returned type "as if" it were a class-wide
14397 interface type.
14398 (Expand_Dispatching_Constructor_Call): Replace call to
14399 Make_DT_Access_Action by direct call to Make_Function_Call.
14400
144012007-06-06 Robert Dewar <dewar@adacore.com>
14402 Ed Schonberg <schonberg@adacore.com>
14403
14404 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14405 compute masking constant, since we now set Esize properly to the
14406 underlying size.
14407 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14408 to match the alignment.
14409 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
14410 packed arrays of 8 bits or less.
14411
14412 * freeze.adb (Freeze_Entity): When freezing the formals of a
14413 subprogram, freeze the designated type of a parameter of an access type
14414 only if it is an access parameter.
14415 Increase size of C convention enumeration object
14416 (Freeze_Entity, array type case): Make sure Esize value is properly
14417 adjusted for the alignment if it is known.
14418 (Freeze_Entity, array type case): When checking bit packed arrays for
14419 the size being incorrect, check RM_Size, not Esize.
14420 (Freeze_Record_Type): Check for bad discriminated record convention
14421 (In_Exp_Body): Return true if the body is generated for a subprogram
14422 renaming, either an attribute renaming or a renaming as body.
14423 (Check_Itype): If the designated type of an anonymous access component
14424 is a non-protected subprogram type, indicate that it is frozen, to
14425 prevent out-of-scope freeze node at some subsequent call.
14426 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
14427 only if the subprogram is neither imported nor exported, as well as the
14428 NCA descriptor class if the subprogram is exported.

14434
14435 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
14436 default initialization on an imported object, when there is no
14437 initialization call generated for it.
14438 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
14439 restriction
14440
14441 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
14442 Static_Elaboration_Desired.
14443 Remove pragma Thread_Body.
14444 Implement a new pragma No_Body
14445 Removes the Explicit_Overriding pragma

14448 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
14449 Pragma_CIL_Constructor): New names.
14450
14451 * sem_cat.adb (Validate_Object_Declaration): An initialization that
14452 uses the equivalent aggregate of a type must be treated as an implicit
14453 initialization.
14454 (Get_Categorization): Check a unit for pragma Preelaborate only if it
14455 has none of the other categories.
14456 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
14457 to apply Import to an object renaming declaration.
14458
14459 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
14460 from a C++ class should be declared as limited and that it will be
14461 considererd limited.
14462 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
14463 should be declared as limited and that it will be considererd limited.
14464 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
14465 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
14466 (Analyze_Pragma): Deal with Universal_Aliasing.
14467 (Sig_Flags): Likewise.
14468 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
14469 (Overflow_Checks_Unsuppressed): New flag.
14470 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
14471 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
14472 case of JVM or .NET targets, and compiling user code.
14473 Add debugging convenience routine rv

144752007-06-06 Robert Dewar <dewar@adacore.com>
14476
14477 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
14478 are interface type.
14479 (Build_Elementary_Input_Call): For floating-point use right type in the
14480 absence of strange size or stream size clauses.
14481 (Build_Elementary_Write_Call): Same fix
14482 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
14483 set to value that does not match base type size.

14486
14487 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
14488 object of a limited type can be initialized with a call to a function
14489 that returns in place. If the limited type has unknown discriminants,
14490 and the underlying type is a constrained composite type, build an actual
14491 subtype from the function call, as is done for private types.
14492 (Side_Effect_Free): An expression that is the renaming of an object or
14493 whose prefix is the renaming of a object, is not side-effect free
14494 because it may be assigned through the renaming and its value must be
14495 captured in a temporary.
14496 (Has_Controlled_Coextensions): New routine.
14497 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
14498 as is done for other limited types.
14499 (Non_Limited_Designated_Type): new predicate.
14500 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
14501 objects.
14502 Remove all handling of with_type clauses.

AC		 14548 Add new warning for renaming of function return objects
14549
14550 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
14551 (Tree_Read): Use size of object instead of type'object_size, since the
14552 latter is incorrect for packed array types.
14553 (Tree_Write): Same fix
14554
14555 * opt.ads: Add new warning for renaming of function return objects
14556 (Generating_Code): New boolean variable used to indicate that the

14567
14568 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
14569 unit is a compilation unit, rather than relying on its scope, so that
14570 Standard can be renamed.
14571 (Analyze_Object_Renaming): Add new warning for renaming of function
14572 return objects.
14573 Also reject attempt to rename function return object in Ada 83 mode.
14574 (Attribute_Renaming): In case of tagged types, add the body of the
14575 generated function to the freezing actions of the type.
14576 (Find_Type): A protected type is visible right after the reserved word
14577 "is" is encountered in its type declaration. Set the entity and type
14578 rather than emitting an error message.
14579 (New_Scope): Properly propagate Discard_Names to inner scopes

14594
14595 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
14596 absolute value of Header.Block_Size when displaying the freed physical
14597 memory in traces.
14598 (Allocate): Compute Storage_Address using Integer_Address, not
14599 Storage_Offset, because the range of Storage_Offset may not be large
14600 enough.
14601 (Configure): New parameter Low_Level_Traces
14602 (Allocate, Deallocation, Free_Physically): Added low-level traces
14603 (Configure): new parameter Errors_To_Stdout.

14605 (Deallocate, Dereference): Send error messages to the proper stream
14606 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
14607 documented. Previous code would send it to the current output file
14608 defined in GNAT.IO, which might not be stdout
14609 (Is_Valid): Adjust comment to mention that a positive reply means that
14610 Header_Of may be used to retrieve the allocation header associated with
14611 the subprogram Storage address argument. Return False early if this
14612 address argument is misaligned.
14613
146142007-06-06 Vincent Celier <celier@adacore.com>
14615
14616 * gnatcmd.adb (GNATCmd): Accept switch -aP for commands that accept
14617 switch -P
14618 (ASIS_Main): New global variable
14619 (Get_Closure): New procedure
14620 (GNATCmd): Set ASIS_Main when -P and -U with a main is used for gnat
14621 check, metric or pretty. Call Get_Closure in this case.
14622 (Check_Files): For GNAT LIST, check all sources of all projects when
14623 All_Projects is True.
14624 (GNATCmd): Accept -U for GNAT LIST
14625
146262007-06-06 Vincent Celier <celier@adacore.com>
14627
14628 * gnatlink.adb (Gnatlink): Do not specify -static-libgcc when --LINK=
14629 has been specified
14630 Correct error message when invocation of the linker fails
14631 Add explicit size clause for the C imported variables
14632 Object_List_File_Supported and Using_GNU_Linker to emphasize that
14633 we expect char size.
14634 Read target parameters earlier, since this is needed to set
14635 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
14636 targets.
14637
146382007-06-06 Vincent Celier <celier@adacore.com>
14639
9e81dbc7 14640 * gnatls.adb:
ec11296f
AC		 14641 Add 3 spaces before the default project directory when displaying
14642 the project search path.
14643 Add new command line switch '-l' to display license information.

14673 before processing the project files.
14674 (Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
14675 specified when symbol policy is Direct. Check that when there is a

14815 to simplify handling of formal interfaces that derive from other formal
14816 interfaces.

14827 declaration, to ensure that the interface list is processed correctly.
14828 (Inline_Instance_Body): If enclosing scope is an instance body, remove
14829 its entities from visibiility as well.
14830 (Pre_Analyze_Actuals): if the actual is an allocator with constraints
14831 given with a named association, analyze the expression only, not the
14832 discriminant association itself.
14833 (Reset_Entity): If the analysis of a selected component is transformed
14834 into an expanded name in the prefix of a call with parameters, do not
14835 transform the original node into an expanded name, to prevent visibility

14837 (Check_Private_View): For an array type, check whether the index types
14838 may need exchanging.

14965 to Void.
14966 (Find_Type_Of_Object): In the case of an access definition, always set
14967 Is_Local_Anonymous_Access. We were previously not marking the anonymous

14986 improve the condition that avoids inheriting the components associated
14987 with secondary tags of the parent.
14988 (Build_Discriminanted_Subtype): Indicate to the backend that the
14989 size of record types associated with dispatch tables is known at

15011 If a component is initialized with a box, check for the presence of a
15012 default expression in its declaration before using its default
15013 initialization procedure.
15014 (Resolve_Record_Aggregate): If a component is box-initialized, and the
15015 component type has a discriminants, create a partial aggregate for it
15016 by copying the discriminants of the component subtype.
15017 Reject attempt to initialize a discriminant with a box.
15018 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
15019 associated with dispatch tables is known at compile time.
15020 (Get_Value): If an association in a record aggregate has a box
15021 association, and the corresponding record component has a default
15022 expression, always copy the default expression, even when the
15023 association has a single choice, in order to create a proper
15024 association for the expanded aggregate.

15033 not null indicator.
15034
15035 * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If

15114 unimplemented unit.
15115 (Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a
15116 manner similar to GNAT.Current_Exception. This is a violation of
15117 restriction (No_Exception_Propagation), and also inhibits the
15118 optimization of local raise to goto.
15119 (Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,
15120 and if so set Most_Recent_Exception_Used flag in Opt, and also check

15131 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): When
15132 concurrent types are declared within an Ada 2005 generic, build their
15133 corresponding record types since they are needed for overriding-related

15135 (Analyze_Protected_Type): Rearrange and simplify code for testing that a
15136 protected type does not implement a task interface or a nonlimited
15137 interface.
15138 (Analyze_Task_Type): Rearrange and simplify code for testing that a task
15139 type does not implement a protected interface or a nonlimited interface.

15141 entity for variable declaration, to ensure that debugging information
15142 is correcty generated.
15143 (Analyze_Protected_Type, Analyze_Task_Type): Do not call expander
15144 routines if the expander is not active.
15145 (Analyze_Task_Body): Mark all handlers to stop optimization of local
15146 raise, since special things happen for task exception handlers.

15205 (Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
15206 (Resolve_Range): Diagnose properly an ambiguous range whose bounds are
15207 character literals.
15208 (Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
15209 Do_Division_Check flag explicitly.
15210 (Resolve_Actuals): If the actual is of a synchronized type, and the
15211 formal is of the corresponding record type, this is a call to a
15212 primitive operation of the type, that is declared outside of the type;
15213 the actual must be unchecked-converted to the type of the actual
15214 (Resolve_Call): Kill all current values for any subprogram call if
15215 flag Suppress_Value_Tracking_On_Call is set.
15216 (Resolve_Type_Conversion): Generate error message the the operand
15217 or target of interface conversions come from a limited view.
15218 (Check_Infinite_Recursion): Ignore generated calls
15219 (Check_Allocator_Discrim_Accessibility): New procedure for checking
15220 that an expression that constrains an access discriminant in an
15221 allocator does not denote an object with a deeper level than the
15222 allocator's access type.
15223 (Resolve_Allocator): In the case of an allocator initialized by an

15242
15243 * sem_ch7.adb (Check_Anonymous_Access_Types): Fix error for null body
15244 (Derive_Inherited_Private_Subprogram): Code cleanup. In case of explicit
15245 overriding of an inherited private subprogram now there is no need to
15246 inherit its dispatching slot and reduce the size of the dispatch table.
15247 Set_All_DT_Position now ensures that the same slot is now assigned to
15248 both entities. This is required to statically build the dispatch table.
15249 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
15250 of calling Set_All_DT_Position to re-evaluate the position of the
15251 entries in the dispatch table. Such reevaluation is not desired if

15280 private extension.
15281 (Type_Access_Level): In the case of a type whose parent scope is a
15282 return statement, call Type_Access_Level recursively on the enclosing
15283 function's result type to determine the level of the return object's
15284 type.
15285 (Build_Elaboration_Entity): Build name of elaboration entity from the
15286 scope chain of the entity, rather than the unit name of the file name.
15287 (Check_Nested_Access): New procedure.

15302 special code on ia64-vms to handle major incompatibilities between the
15303 GCC unwinding ABI and the VMS Condition Handling Facility, both calling
15304 this routine with a very different set of arguments and expectations on
15305 the return value.

15322 (Rmsg_28): Fix description for E.4(18) check.
15323 (Raise_Current_Excep): Call Debug_Raise_Exception just before

15329 (Local_Raise): Moved to System.Exceptions
15330
15331 * s-finimp.adb (Raise_From_Finalize): Code to construct an appropriate

16263 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
16264 stubbed procedure with a null body, replace the call with a null
16265 statement without using the full inlining machinery, for efficiency
16266 and to avoid invalid values in source file table entries.

16357
16358 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
16359 for all access attributes, because overload resolution should work the
16360 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
16361 causes the error message for the ambiguous "X'Access = Y'Access" and
16362 "X'Unrestricted_Access = Y'Access" and so forth to match.
16363 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,

16375 that use (a subtype of) the class-wide type of the enclosing type.
16376 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
16377 Derived_Type for Prev formal on call to
16378 Check_Anonymous_Access_Components rather than Empty.
16379 (Make_Incomplete_Type_Declaration): Add test for case where the type has
16380 a record extension in deciding whether to create a class-wide type,
16381 rather than just checking Tagged_Present.

16383 to stand-alone object declarations as well as component declarations.
16384 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to

16409 to private type.
16410 (Analyze_Subtype_Declaration): For an access subtype declaration, create

16461 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
16462 when -gnatg is not specified.

16514 parameter of the containing subprogram.
16515 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling

16535 initialize most the TSD components by means of an aggregate.
16536 Modify the declaration of the object containing the TSD
16537 because we now expand code that has a higher level of abstraction.
16538 The TSD has a discriminant containing the Inheritance Depth Level,
16539 value that is used in the membership test but also to fix the size
16540 of the table of ancestors.
16541 (Expand_Interface_Conversion): Insert function body at the closest place

16577 (Get_Remotely_Callable): Subprogram removed.
16578 (Init_Predefined_Interface_Primitives): Replace generation of call to
16579 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16580 Prims.
16581
16582 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16583 First (Parameter_Associations ()) with the call to First_Actual that

16598 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16599 support concurrent types implementing interfaces.
16600 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16601 specify kind Any_Limited_Interface, and this functionality is already
16602 provided by the function Has_Abstract_Interfaces.
16603 (Remove_Side_Effects): replace Controlled_Type by
16604 CW_Or_Controlled_Type whenever the issue is related to
16605 using or not the secondary stack.
16606
16607 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16608 P_Interface_Type_Definition to fulfill the new interface (the formal

16649 type, do not create a new itype for each protected body.
16650 If the body of a protected operation creates
16651 controlled types (including allocators for class-widetypes), the
16652 body of the corresponding protected subprogram must include a
16653 finalization list.
16654 (Build_Activation_Chain_Entity): Build the chain entity for extended
16655 return statements.
16656 (Type_Conformant_Parameters): Use common predicate Conforming_Types
16657 to determine whether operation overrides an inherited primitive.

16659 for a possible overriding candidate.
16660 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16661 hold an actual parameter value since its initialization is separated
16662 from the the declaration. Prevents errors on null-excluding access
16663 formals.

AC		 16667
16668 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16669 Do an Unchecked_Conversion to handle the passage from the Underlying
16670 Type to the Base Type when calling Build_To_Any_Call and
16671 Build_From_Any_Call.
16672 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16673 E_Constant, depending upon Variable formal.
16674 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16675 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16676 parameter that requires an extra constrained parameter, declare
16677 temporary for actual as a variable, not a constant.
16678 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16679 the unit being compiled is the one that contains the stub type.
16680 Change primitive operation name for the RACW associated with a RAS
16681 from Call to _Call so it cannot clash with any legal identifier.
16682 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16683 Is_RAS.
16684 (Append_RACW_Bodies): New subprogram.
16685 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16686 Add_Receiving_Stubs_To_Declarations functions.
16687 When expanding a package body, this list correspond to the
16688 statements in the HSS at the end of the pacakge.
16689 When expanding a package spec, this list correspond to the
16690 spec declarations.
16691 (Add_Receiving_Stubs_To_Declarations): Append the function
16692 registering the receiving stubs at the end of the 'Stmts' list.
16693 (RCI_Package_Locator): Pass the new Version generic formal when
16694 instantiating a RCI_Locator package.
16695 (Build_From_Any_Function): To compute the High bound for an
16696 unconstrained array actual, we add the Low bound with the length.
16697 Thus we must convert the low bound and the length to an appropriate
16698 type before doing the sum.
16699 (Build_Subprogram_Receiving_Stubs, PolyORB):
16700 * Retrieve the extra formals parameters at the
16701 end of the parameter stream.
16702 * Use Move_Any_Value to write back out parameters
16703 after executing the request as it is more efficient
16704 than Copy_Any_Value.
16705 * Build the any containing Extra Formals with the
16706 appropriate typecode.
16707 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16708 empty Component_List.
16709 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

16711 in server-side stubs.
16712 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16713 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16714 Use Build_Actual_Object_Declaration to prepare the actuals.
16715 (Add_Parameter_To_NVList): Set the parameter mode to In for
16716 Extra Constrained Parameters.
16717 (Build_General_Calling_Stubs): Set the parameter type to boolean for
16718 Extra Constrained parameters.
16719 (Build_To_Any_Function, Build_From_Any_Function,
16720 Built_TypeCode_Function): When Typ is implicit, call the correct
16721 function with the first not implicit parent type.
16722 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16723 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16724 typecode from the Etype. Therefore we retrieve the correct typecode
16725 with a call to Get_Any_Type.
16726 (Copy_Specification): Do controlling formal type substitution based on
16727 Is_Controlling_Formal flag, instead of caller-provided object type.
16728 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16729 a RACW primitive operation, we might get a subprogram declaration for an
16730 ancestor of the RACW designated type (not for the designated type
16731 itself), in the case where this operation is inherited. In this case we
16732 have no easy means of determining the original tagged type for which
16733 the primitive was declared, so instead we now rely on
16734 Copy_Specification to use the Is_Controlling_Formal flag to determine
16735 which formals require type substitution.

16741 GNAT.Current_Exception are not allowed if pragma Restrictions
16742 (No_Exception_Propagation) is set and in any case make the associated
16743 handler unsuitable as a target for a local raise statement.
16744 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16745 run-time subprogram CW_Membership by call to Build_CW_Membership.
16746 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16747 by a function call, a temporary must be created before expanding the
16748 Constructor_Call itself, to prevent out-of-order elaboration in the
16749 back-end when stack checking is enabled..

16769 initialization procedure for the type is not available.
16770 (Resolve_Record_Aggregate): Check that a choice of an association with a
16771 box corresponds to a component of the type.
16772 (Resolve_Record_Aggregate): Split Is_Abstract flag into
16773 Is_Abstract_Subprogram and Is_Abstract_Type.

16833 in a project file when calling gnatstack. Parse the -U flag for
16834 processing files belonging to all projects in the project tree.
16835 Remove all processing for command Setup

16875
16876 * mingw32.h (S2WSU): New macro to convert from a string to a
16877 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16878 standard 8bits encoding.
16879 (WS2SU): As above but converting from wide-sring to string.
16880 This is needed as it is necessary to have access to both versions in the
16881 runtime for the form parameter encoding support.
16882 This set of patch add support for the encoding form parameter.
16883 (S2WS): Improve implementation to handle cases where the filename is not
16884 UTF-8 encoded. In this case we default to using the current code page
16885 for the conversion.
16886
16887 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16888 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16891 (freopen): Idem.
16892
16893 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
16894 encoding. This is needed for the Reset routine (freopen low level-call).

16934 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16935 implementation of floating point operations as native x86 targets.
16936 So the FPU should be initialized in the same way using finit. Fix
16937 floating point operations accuracy issues.
16938 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16939 member in struct sigaction, so as to avoid warning for incompatible
16940 pointer types.

17027 errors in other cases. Don't give the error unless the "not null"
17028 parses properly. Correct the source position at which the error occurs.
17029 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to

17083
17084 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
17085 switches, without repetition of "eD". Make sure that last character of
17086 -gnatep= switch is not taken as -gnat switch character.
17087 Complete rewrite of circuit for handling saving compilation options
17088 Occasioned by need to support dot switchs for -gnatw, but cleans up
17089 things in general.
17090 -gnatX does not affect Ada_Version
17091 Include -gnatyA in -gnatg style switches
17092

17106 the default project path, initially done during elaboration of the
17107 package.
17108 If the prefix returned by Sdefault is null, get the prefix from a call
17109 to Executable_Prefix_Path.
17110 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
17111 null.
17112
17113 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
17114 canonical directory name to open the directory from which files are
17115 retrieved.
17116 (Record_Other_Sources): Idem.
17117 (Locate_Directory): Add the possibility to create automatically missing
17118 directories when Setup_Projects is True.
17119 Call Locate_Directory so that the directory will be created when
17120 Setup_Projects is True, for object dir, library dir, library ALI dir,
17121 library source copy dir and exec dir.
17122
17123 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older

171632007-04-06 Ed Schonberg <schonberg@adacore.com>
17164
17165 * sem_ch10.adb (Install_Limited_Context_Clauses.
17166 Expand_Limited_With_Clause): Use a new copy of selector name in the
17167 call to Make_With_Clause. This fixes the tree structure for ASIS
17168 purposes. Nothing is changed in the compiler behaviour.
17169 (Process_Body_Clauses): Handle properly use clauses whose prefix is
17170 a package renaming.
17171 (Install_Limited_With_Clauses): Do not install non-limited view when it
17172 is still incomplete.

17176
17177 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
17178 when capturing size information, instead of base type, which for a
17179 formal array type will be the unconstrained type.
17180 (Analyze_Formal_Object_Declaration): Add check for illegal default
17181 expressions for a formal in object of a limited type.
17182 (Instantiate_Object): Ditto.
17183 (Check_Formal_Package_Instance): Skip entities that are formal objects,
17184 because they were defaulted in the formal package and no check applies
17185 to them.
17186 (Check_Formal_Package_Instance): Extend conformance check to other
17187 discrete types beyond Integer.
17188 (Process_Default): Copy directly the unmatched formal. A generic copy
17189 has already been performed in Analyze_Formal_Package.
17190 (Analyze_Associations): If a formal subprogram has no match, check for
17191 partial parametrization before looking for a default, to prevent
17192 spurious errors.
17193 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
17194 not set the instantiation environment before analyzing the actuals.
17195 Fixes regression on 8515-003 with implementation of AI-133.
17196 Set_Instance_Env checks whether the generic unit is a predefined
17197 unit, in which case the instance must be analyzed with the latest Ada
17198 mode. This setting must take place after analysis of the actuals,
17199 because the actuals must be analyzed and frozen in the Ada mode extant
17200 outside of the current instantiation.
17201 (Save_Env, Restore_Env): Preserve and restore the configuration
17202 parameters so that predefined units can be compiled in the proper Ada
17203 mode.
17204 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
17205 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
17206 and Is_Abstract_Type.
17207 (Analyze_Formal_Package): For better error recovery, Add exception
17208 handler to catch Instantion_Error, which can be raised in
17209 Analyze_Associations

17213 Gary Dismukes <dismukes@adacore.com>
17214
17215 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
17216 prefix type is a discriminated subtype of the type of the formal.
17217 (Analyze_Allocator): Collect all coextensions regardless of the context.
17218 Whether they can be allocated statically is determined in exp_ch4.
17219 (Analyze_Selected_Component): If the prefix is a limited view and the
17220 non-limited view is available, use the non-limited one.
17221 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
17222 therefore illegal), suggest a qualified expression rather than a type
17223 conversion, because a type conversion would be illegal in this context.
17224 (Anayze_Allocator): Trace recursively all nested allocators so that all
17225 coextensions are on the corresponding list for the root. Do no mark
17226 coextensions if the root allocator is within a declaration for a stack-
17227 allocated object, because the access discriminants will be allocated on
17228 the stack as well.
17229 (Analyze_Call): Remove restriction on calls to limited functions for the
17230 cases of generic actuals for formal objects, defaults for formal objects
17231 and defaults for record components.
17232 (Analyze_Allocator): Before analysis, chain coextensions on the proper
17233 element list. Their expansion is delayed until the enclosing allocator
17234 is processed and its finalization list constructed.
17235 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
17236 for an operation with the given name among the primitive operations of
17237 the corresponding record type.
17238 (Analyze_Selected_Component): If the prefix is a task type that
17239 implements an interface, and there is no entry with the given name,
17240 check whether there is another primitive operation (e.g. a function)
17241 with that name.
17242 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
17243 properly the indexing of a function call written in prefix form, where
17244 the function returns an array type, and all parameters of the function
17245 except the first have defaults.
17246 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
17247 the original operands, rather than relocating them, for efficiency and
17248 to work properly when an operand is overloaded.
17249 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
17250 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
17251 (Analyze_Selected_Component): If the prefix is a private extension, only
17252 scan the visible components, not those of the full view.
17253 (Try_Primitive_Operation): If the operation is a procedure, collect all
17254 possible interpretations, as for a function, because in the presence of
17255 classwide parameters several primitive operations of the type can match
17256 the given arguments.

17262 tag-indeterminate call to an abstract function, when the left-hand side
17263 is not classwide.
17264 (Analyze_Loop_Statement): Improve detection of infinite loops

17268
17269 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
17270 out of Analyze_Package_Declaration, because processing must be applied
17271 to package bodies as well, for deferred constants completed by pragmas.
17272 (Analyze_Package_Declaration): When the package declaration being
17273 analyzed does not require an explicit body, call Check_Completion.
17274 (May_Need_Implicit_Body): An implicit body is required when a package
17275 spec contains the declaration of a remote access-to-classwide type.
17276 (Analyze_Package_Body): If the package contains RACWs, append the
17277 pending subprogram bodies generated by exp_dist at the end of the body.
17278 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
17279 Is_Abstract_Subprogram and Is_Abstract_Type.
17280 (Preserve_Full_Attributes): The full entity list is not an attribute
17281 that must be preserved from full to partial view.
17282
9e81dbc7
AS		 17283 * sem_dist.adb (Add_RAS_Dereference_TSS):
17284 Change primitive name to _Call so it cannot clash with any legal
17285 identifier, and be special-cased in Check_Completion.
17286 Mark the full view of the designated type for the RACW associated with
17287 a RAS as Comes_From_Source to get proper view switching when installing
17288 private declarations.
17289 Provite a placeholder nested package body along with the nested spec
17290 to have a place for Append_RACW_Bodies to generate the calling stubs
17291 and stream attributes.

17297 that is a limited view, check the non-limited view if available.
17298 (Undefined): Refine error message for missing with of Text_IO
17299 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
17300 to distinguish real missing with cases.
17301 Fix format of all missing with messages
17302 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
17303 renaming as body when renamed entity is abstract.

17307
17308 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
17309 predicate recursive, to handle complex expressions on literals whose
17310 spurious ambiguity comes from the abstract interpretation of some
17311 subexpression.
17312 (Interface_Present_In_Ancestor): Add support to concurrent record
17313 types.
17314 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into

17319
17320 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
17321 dereference of a local object R created as a reference to another
17322 object O, use the access level of O.
17323 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
17324 rather than local Same_Formal_Type, to check whether protected operation
17325 overrides an inherited one.
17326 (Same_Formal_Type): New predicate, used when matching signatures of
17327 overriding synchronized operations, to handle the case when a formal
17328 has a type that is a generic actual.
17329 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
17330 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
17331 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
17332 syntactic ambiguities involving indexing of function calls that return
17333 arrays.
17334 (Abstract_Interface_List): New subprogram that returns the list of
17335 abstract interfaces associated with a concurrent type or a
17336 concurrent record type.
17337 (Interface_Present_In_Parent): New subprogram used to check if a
17338 given type or some of its parents implement a given interface.
17339 (Collect_Abstract_Interfaces): Add support for concurrent types
17340 with interface types.
17341 (Has_Abstract_Interfaces): Add support for concurrent types with
17342 interface types.
17343 (Is_Parent): New subprogram that determines whether E1 is a parent
17344 of E2. For a concurrent type its parent is the first element of its
17345 list of interface types; for other types this function provides the
17346 same result than Is_Ancestor.
17347 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
17348 (Collect_Synchronized_Interfaces): Removed because the subprogram
17349 Collect_Abstract_Interfaces provides this functionality.
17350 (Collect_Abstract_Interfaces): Minor update to give support to
17351 concurrent types and thus avoid undesired code duplication.
17352 (Get_Subprogram_Entity): Handle entry calls.
17353 (May_Be_Lvalue): Include actuals that appear as in-out parameters in

17395 high bound is constant and the slice is empty. Tidy.
17396 (tree_transform, case N_Op_Not): Handle properly the case where the
17397 operation applies to a private type whose full view is a modular type.
17398 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
17399 Address_Clause, use the associated Expression as the GNAT tree
17400 representing the choice value to ensure the corresponding GCC tree is
17401 of the proper kind.
17402 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
17403 instead of just the operands, as the base GCC stabilize_reference does.

17413 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
17414 remainder, avoiding the cost of a multiplication and a subtraction.
17415 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
17416 provides both quotient and remainder in a single computation.

17860
17861 * adaint.c (__gnat_get_libraries_from_registry): Call explicitly the

17911 imported_p.
17912 <E_Access_Type>: Use the Non_Limited_View as the full view of the

17930 (gnat_to_gnu_entity): When generating a type representing
17931 a Character or Wide_Character type, set the flag TYPE_STRING_FLAG,
17932 so that debug writers can distinguish it from ordinary integers.

17955 expression into a SAVE_EXPR if stabilization failed.
17956
17957 * utils.c (create_subprog_decl): Turn TREE_ADDRESSABLE on the type of
17958 a result decl into DECL_BY_REFERENCE on this decl, now what is expected
17959 by lower level compilation passes.
17960 (gnat_genericize): New function, lowering a function body to GENERIC.
17961 Turn the type of RESULT_DECL into a real reference type if the decl

17969 rest_of_decl_compilation, to make sure that field TYPE_NAME of
17970 type_decl is properly set before calling the debug information writers.
17971 (write_record_type_debug_info): The heuristics which compute the
17972 alignment of a field in a variant record might not be accurate. Add a
17973 safety test to make sure no alignment is set to a smaller value than
17974 the alignment of the field type.
17975 (make_dummy_type): Use the Non_Limited_View as the underlying type if
17976 the type comes from a limited_with clause. Do not loop on the full view.

18003 (create_true_var_decl): New function, similar to create_var_decl but
18004 forcing the creation of a VAR_DECL node (CONST_DECL not allowed).

18017 * trans.c (process_freeze_entity): Don't abort if we already have a
18018 non dummy GCC tree for a Concurrent_Record_Type, as it might
18019 legitimately have been elaborated while processing the associated
18020 Concurrent_Type prior to this explicit freeze node.
18021 (Identifier_to_gnu): Do not make a variable referenced in a SJLJ

18219 (Make_DT): If the ancestor of the type is a CPP_Class and we are
18220 compiling under full ABI compatibility mode we avoid the generation of
18221 calls to run-time services that fill the dispatch tables because under
18222 this mode we currently inherit the dispatch tables in the IP subprogram.
18223 (Write_DT): Emit an "is null" indication for a null procedure primitive.
18224 (Expand_Interface_Conversion): Use an address as the type of the formal
18225 of the internally built function that handles the case in which the

18234 * bindusg.ads, bindusg.adb:
18235 Change to package and rename procedure as Display, which
18236 now ensures that it only outputs usage information once.

18260 where discriminants may be used for the bounds of entry families.
18261 (Apply_Address_Clause_Check): Remove side-effects if address expression
18262 is non-static and is not the name of a declared constant.

18276 we request a discriminal value only in case of discriminants.
18277 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
18278 assignments where the target subtype is unconstrained and the target

18394 the parent part is a build-in-place function call, generate assignments.
18395 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
18396 are build-in-place function calls.
18397 (Replace_Self_Reference): New subsidiary of
18398 Make_OK_Assignment_Statement, to replace an access attribute that is a
18399 self-reference into an access to the appropriate component of the
18400 target object. Generalizes previous mechanism to handle self-references
18401 nested at any level.
18402 (Is_Self_Referential_Init): Remove, not needed.
18403 (Is_Self_Referential_Init): New predicate to simplify handling of self
18404 referential components in record aggregates.

18406 check for presence of entity before checking for self-reference.
18407 (Has_Default_Init_Comps): Return True if a component association is a
18408 self-reference to the enclosing type, which can only come from a
18409 default initialization.
18410 (Make_OK_Assignment_Statement): If the expression is of the form
18411 Typ'Acc, where Acc is an access attribute, the expression comes from a
18412 default initialized self-referential component.
18413 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
18414 that has been derived from several abstract interfaces we must also
18415 initialize the tags of the secondary dispatch tables.

9e81dbc7 18422 * exp_attr.adb:
6f7f72f9
EB		 18423 (Expand_Access_To_Protected_Op): If the context indicates that an access
18424 to a local operation may be transfered outside of the object, create an
18425 access to the wrapper operation that must be used in an external call.
70198b9f
AC		 18426 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
18427 target, pass the Valid attribute applied to a floating-point prefix on
18428 to the back end without expansion.
18429 (Storage_Size): Use the new run-time function Storage_Size to retrieve
18430 the allocated storage when it is specified by a per-object expression.
18431 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
18432 Nothing to do here, the attribute has been rewritten during semantic
18433 analysis.
18434 (Expand_Attribute_Reference): Handle expansion of the new Priority
18435 attribute
18436 (Find_Fat_Info): Handle case of universal real
18437 (Expand_Access_To_Protected_Op): Fix use of access to protected
18438 subprogram from inside the body of a protected entry.
18439 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
18440 'Access and 'Unrestricted_Access, to transform the attribute reference
18441 into a fat pointer.
18442 (Is_Constrained_Aliased_View): New predicate to help determine whether a
18443 subcomponent's enclosing variable is aliased with a constrained subtype.
18444 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
18445 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
18446 an aliased prefix must be known to be constrained in order to use True
18447 for the attribute value, and now it's possible for some aliased views
18448 to be unconstrained.
18449
184502006-10-31 Robert Dewar <dewar@adacore.com>

18460
6f7f72f9 18461 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
70198b9f
AC		 18462 register in the final list objects containing class-wide interfaces;
18463 otherwise we incorrectly register the tag of the interface in the final
18464 list.
6f7f72f9
EB		 18465 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
18466 generate the wrapper if the parent primitive is abstract. This is
18467 required to report the correct error message.
18468 (Expand_N_Subtype_Indication): Do validity checks on range
70198b9f
AC		 18469 (Clean_Task_Names): If an initialization procedure includes a call to
18470 initialize a task (sub)component, indicate that the procedure will use
18471 the secondary stack.
18472 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
18473 compatibility for interfacing with CPP by default.
18474 (Expand_N_Object_Declaration): Only build an Adjust call when the
18475 object's type is a nonlimited controlled type.
18476 * exp_ch3.adb: Add with and use of Exp_Ch6.
18477 (Expand_N_Object_Declaration): Check for object initialization that is a
18478 call to build-in-place function and apply Make_Build_In_Place_Call_In_
18479 Object_Declaration to the call.
18480 (Freeze_Type): When the designated type of an RACW was not frozen at the
18481 point where the RACW was declared, validate the primitive operations
18482 with respect to E.2.2(14) when it finally is frozen.
18483 (Build_Initialization_Call,Expand_Record_Controller): Rename
18484 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18485 return-by-reference has no meaning in Ada 2005.
18486 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
18487 to register tag of the immediate ancestor interfaces in the
18488 run-time structure.
18489 (Init_Secondary_Tags): Moved to the specification to allow the
18490 initialization of extension aggregates with abstract interfaces.
18491 (Build_Master_Renaming): Make public, for use by function declarations
18492 whose return type is an anonymous access type.
18493 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18494 Insert_List_Before_And_Analyze after the generation of the specs
18495 associated with null procedures.
18496 (Expand_Tagged_Root): Update documentation in its specification.
18497 (Init_Secondary_Tags): Update documentation.
18498 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18499 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18500 then generate code to inherit the contents of the dispatch table
18501 directly from the ancestor.
18502 (Expand_Record_Controller): Insert controller component after tags of
18503 implemented interfaces.
18504 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
18505 create null procedure overridings when null procedures are inherited
18506 from interfaces.
18507 (Make_Null_Procedure_Specs): New procedure to generate null procedure
18508 declarations for overriding null primitives inherited from interfaces.
18509 (Is_Null_Interface_Procedure): New function in
18510 Make_Null_Procedure_Specs.
18511 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18512 immediate ancestor of a tagged type is an abstract interface type we
18513 must generate the specification of the predefined primitives associated
18514 with controlled types (because the dispatch table of the ancestor is
18515 null and hence these entries cannot be inherited). This is required to
18516 elaborate well the dispatch table.

AC		 18527 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
18528 (Expand_N_Allocator): For "new T", if the object is constrained by
18529 discriminant defaults, allocate the right amount of memory, rather than
18530 the maximum for type T.
18531 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18532 when the allocator is initialized by a build-in-place call, since the
18533 allocator is already rewritten as a reference to the function result,
18534 and this prevents an unwanted duplication of the function call.
18535 Add with and use of Exp_Ch6.
18536 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18537 is a call to build-in-place function and apply
18538 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18539 untagged designated types).
18540 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18541 optimization if source or target is biased.
18542 (Expand_N_Allocator): Add comments for case of an allocator within a
18543 function that returns an anonymous access type designating tasks.
18544 (Expand_N_Allocator): apply discriminant checks for access
18545 discriminants of anonymous access types (AI-402, AI-416)

70198b9f
AC		 18555 (Expand_N_Assignment_Statement): Call
18556 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
18557 build-in-place function call. Currently, this can happen only for
18558 assignments that come from aggregates.
18559 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18560 in order to alleviate the upward compatibility introduced by AI-318.
18561 (Expand_N_Extended_Return_Statement): Add support for handling the
18562 return object as a build-in-place result.
18563 (Expand_Non_Function_Return): Implement simple return statements nested
18564 within an extended return.
18565 (Enable_New_Return_Processing): Turn on the new processing of return
18566 statements.
18567 (Expand_Non_Function_Return): For a return within an extended return,
18568 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18569 (Expand_N_Extended_Return_Statement): Implement AI-318
18570 (Expand_Simple_Function_Return): Ditto.
18571 (Expand_N_If_Statement): Handle new -gnatwt warning
18572 (Expand_N_Case_Statement): Handle new -gnatwt warning
18573 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18574 a protected object.
18575 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18576 validity checking of assignments to elementary record components.
18577 (Expand_N_Return_Statement): return Class Wide types on the secondary
18578 stack independantly of their controlled status since with HIE runtimes,
18579 class wide types are not potentially controlled anymore.
18580
18581 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18582 node kind.
18583
18584 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18585 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18586 it expects a block, procedure, or task. The return statement will get
18587 turned into a block, and Expand_Cleanup_Actions will happen then.

18593
18594 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18595 capability.
18596 (Expand_Inlined_Call): Tagged types are by-reference types, and
18597 therefore should be replaced by a renaming declaration in the expanded
18598 body, as is done for limited types.
18599 (Expand_Call): If this is a call to a function with dispatching access
18600 result, propagate tag from context.
18601 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18602 CPP by default.
18603 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18604 build-in-place when the right-hand side of an assignment is a
18605 build-in-place function call.
18606 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18607 of the explicit dereference of the allocator to the result subtype of
18608 the build-in-place function. This is needed to satisfy type checking
18609 in cases where the caller's return object is created by an allocator for
18610 a class-wide access type and the type named in the allocator is a
18611 specific type.
18612 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18613 conversion of the reference to the declared object to the result subtype
18614 of the build-in-place function. This is needed to satisfy type checking
18615 in cases where the declared object has a class-wide type. Also, in the
18616 class-wide case, change the type of the object entity to the specific
18617 result subtype of the function, to avoid passing a class-wide object
18618 without explicit initialization to the back end.
18619 (Register_Interface_DT_Entry): Moved outside the body of
18620 Freeze_Subprogram because this routine is now public; it is called from
18621 Check_Dispatching_Overriding to handle late overriding of abstract
18622 interface primitives.
18623 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18624 adding an implicit access actual on a call to a build-in-place function.
18625 (Expand_Actuals): Test for an actual parameter that is a call to a
18626 build-in-place function and apply
18627 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18628 (Is_Build_In_Place_Function): New function to determine whether an
18629 entity is a function whose calls should be handled as build-in-place.
18630 (Is_Build_In_Place_Function_Call): New function to determine whether an
18631 expression is a function call that should handled as build-in-place.
18632 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18633 calls to build-in-place functions as the initialization of an allocator.
18634 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18635 handling calls to build-in-place functions in contexts that do not
18636 involve init of a separate object (for example, actuals of subprogram
18637 calls).
18638 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18639 handling calls to build-in-place functions as the initialization of an
18640 object declaration.
18641 (Detect_Infinite_Recursion): Add explicit parameter Process to
18642 instantiation of Traverse_Body to avoid unreferenced warning.
18643 (Check_Overriding_Inherited_Interfaces): Removed.
18644 (Register_Interface_DT_Entry): Code cleanup.
18645 (Register_Predefined_DT_Entry): Code cleanup.
18646 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18647 inlined statements if within a transient scope.
18648 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18649 formal parameters with occurrences of actuals in inlined body, establish
18650 visibility on the proper view of the actual's subtype for the body's
18651 context.
18652 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18653 compatibility mode and we have an imported CPP subprogram because
18654 for now we assume that imported CPP primitives correspond with
18655 objects whose constructor is in the CPP side (and therefore we
18656 don't need to generate code to register them in the dispatch table).
18657 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18658 aligned selected component.
18659 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18660 the actual of an in-mode parameter is a type conversion.
18661 (Expand_Actuals): If the call does not come from source and the actual
18662 is potentially misaligned, let gigi handle it rather than rejecting the
18663 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18664 Class Wide types as returning by reference independantly of their
18665 controlled status since with HIE runtimes class wide types are not
18666 potentially controlled anymore.

70198b9f
AC		 18691 subprogram Ids, even if they are not yet assigned.

18693 calling Assign_Subprogram_Ids if necessary.
18694 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18695 should be done only once they are assigned.
18696 (Build_From_Any_Function, case of tagged types): Add missing call to
18697 Allocate_Buffer.
18698 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18699 type for an RACW type.
18700 (Add_RACW_Features): When processing an RACW declaration for which the
18701 designated type is already frozen, enforce E.2.2(14) rules immediately.
18702 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18703 special reordering of controlling formals.
18704

18710 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18711 fixed-point operations in an integer context, i.e. as operands of a
18712 conversion to an integer type, indicate that result must be rounded.
18713
187142006-10-31 Robert Dewar <dewar@adacore.com>
18715
18716 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18717 cases, pass the encoding method, since it is now required by the run
18718 time.
18719
18720 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18721 assumption that Str'First = 1.
18722 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18723 it on to the Value_Wide_Wide_Character call.
18724 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18725 properly handles a string of the form quote-encoded_wide_char-quote.
18726
18727 * s-wchcnv.adb: Minor reformatting

187352006-10-31 Robert Dewar <dewar@adacore.com>
18736
18737 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18738 Machine_Attribute pragma internally to implement the user pragma.
18739 Add processing for pragma Interface so that it is now completely
18740 equivalent to pragma Import.
18741
18742 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18743 so that it can be applied to all entities, including record components
18744 and enumeration literals.
18745 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18746 priority ranges are correct, verify compatibility against task
18747 dispatching and locking policies, and if everything is correct an entry
18748 is added to the table containing priority specific dispatching entries
18749 for this compilation unit.
18750 (Delay_Config_Pragma_Analyze): Delay processing
18751 Priority_Specific_Dispatching pragmas because when processing the
18752 pragma we need to access run-time data, such as the range of
18753 System.Any_Priority.
18754 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18755 Allow pragma Unreferenced as a context item
18756 Add pragma Preelaborable_Initialization
18757 (Analyze_Pragma, case Interface): Interface is extended so that it is

18760 insertion characters.
18761 Add handling for Pragma_Wide_Character_Encoding
18762 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18763 never supercedes a real restriction, and that a real restriction
18764 always supercedes a warning.
18765 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
18766 appropriate form.

18771
18772 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18773 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18774 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18775 in Ada 2005.
18776 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18777 type of the function containing a return statement, because the
18778 Return_Type field was removed. We now use the Return_Applies_To field.
18779
6f7f72f9 18780 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
70198b9f
AC		 18781 (Build_Task_Image_Decl): If procedure is not called from an
18782 initialization procedure, indicate that function that builds task name
18783 uses the sec. stack. Otherwise the enclosing initialization procedure
18784 will carry the indication.
18785 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18786 N_Object_Declaration instead.
18787 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18788 conditional dead code killed, and change implementation accordingly.
18789 (Insert_Actions): Add N_Return_Object_Declaration case.
18790 Correct comment to mention N_Extension_Aggregate node.
18791 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18792 attempts to save information for global variables which cannot be
18793 safely tracked.
18794 (Get_Current_Value_Condition): Handle conditions the other way round
18795 (constant on left). Also handle right operand of AND and AND THEN
18796 (Set_Current_Value_Condition): Corresponding changes
18797 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18798 (Get_Current_Value_Condition): Handle simple boolean operands
18799 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18800 (Get_Current_Value_Condition): If the variable reference is within an
18801 if-statement, does not appear in the list of then_statments, and does
18802 not come from source, treat it as being at unknown location.
18803 (Get_Current_Value_Condition): Enhance to allow while statements to be
18804 processed as well as if statements.
18805 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18806 come from source.
18807 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18808 of loop. This is safe now that we fixed Kill_Current_Values.
18809 (OK_To_Do_Constant_Replacement): Check whether current scope is
18810 Standard, before examining outer scopes.

18833 (Generate_Reference): Accept an implicit reference generated for a
18834 default in an instance.
18835 (Generate_Reference): Accept a reference for a node that is not in the
18836 main unit, if it is the generic body corresponding to an subprogram
18837 instantiation.

AC		 18842 -gnatwq/Q.
18843 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18844 exception handler.
18845 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18846 use clauses, to avoid messages on packages used to qualify, and also
18847 to avoid messages from obsolescent units.
18848 (Warn_On_Useless_Assignments): Don't generate messages for imported
18849 and exported variables.
18850 (Warn_On_Useless_Assignments): New procedure

188582006-10-31 Olivier Hainque <hainque@adacore.com>
18859
18860 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the

18864 Robert Dewar <dewar@adacore.com>
18865 Ed Schonberg <schonberg@adacore.com>
18866
18867 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18868 Ada 95 mode, because it violates the new rules for AI-318.
18869
18870 * g-awk.ads: Use overloaded subprograms in every case where we used to
18871 have a default of Current_Session. This makes the code closer to be
18872 correct for both Ada 95 and 2005.
18873
18874 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18875 code, relying on the fact that the compiler generates a warning
18876 instead of an error in -gnatg mode.
18877
18878 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18879 E_Return_Statement entity kind.
18880 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18881
18882 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18883 report an error if the reserved word abstract has been previously found.
18884 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
6f7f72f9
EB		 18885
18886 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
70198b9f
AC		 18887 parenthesized range attribute usage
18888 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18889
18890 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18891 in the syntax for extended_return_statement. This is not in the latest
18892 RM, but the ARG is expected to issue an AI allowing this.
18893 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18894 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18895 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18896 P_Return_Statement): Parse the new syntax for extended_return_statement.
18897
18898 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18899 Output_End_Missing): Add error-recovery code for the new
18900 extended_return_statement syntax; that is, the new E_Return entry on
18901 the scope stack.
18902
18903 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18904 limited to nonlimited, because otherwise we violate the new Ada 2005
18905 rules about returning limited types in function Create_AST_Handler in
18906 s-asthan.adb.
18907
18908 * sem.adb (Analyze): Add cases for new node kinds
18909 N_Extended_Return_Statement and N_Return_Object_Declaration.
18910
18911 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18912 type is in the same category as type of context before applying check,
18913 to prevent anomalies in instantiations.
18914 (Resolve_Aggregate): Remove test for limited components in aggregates.
18915 It's unnecessary in Ada 95, because if it has limited components, then
18916 it must be limited. It's wrong in Ada 2005, because limited aggregates
18917 are now allowed.
18918 (Resolve_Record_Aggregate): Move check for limited types later, because
18919 OK_For_Limited_Init requires its argument to have been resolved.
18920 (Get_Value): When copying the component default expression for a
18921 defaulted association in an aggregate, use the sloc of the aggregate
18922 and not that of the original expression, to prevent spurious
18923 elaboration errors, when the expression includes function calls.
18924 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18925 were missing. We also didn't handle qualified expressions. Now also
18926 allow function calls. Use new common routine OK_For_Limited_Init.
18927 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18928 with space can upper case letter).
18929
6f7f72f9 18930 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
70198b9f 18931 Has_Static_Discriminants flag
6f7f72f9
EB		 18932 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18933 type with discriminants.
18934 (Process_Range_Expr_In_Decl): Do validity checks on range
70198b9f
AC		 18935 (Build_Discriminant_Constraints): Use updated form of
18936 Denotes_Discriminant.
18937 (Process_Subtype): If the subtype is a private subtype whose full view
18938 is a concurrent subtype, introduce an itype reference to prevent scope
18939 anomalies in gigi.
18940 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18941 Record_Type_Declaration): The functionality of the subprograms
18942 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18943 is now performed by a single routine.
18944 (Build_Derived_Record_Type): If the type definition includes an explicit
18945 indication of limitedness, then the type must be marked as limited here
18946 to ensure that any access discriminants will not be treated as having
18947 a local anonymous access type.
18948 (Check_Abstract_Overriding): Issue a detailed error message when an
18949 abstract subprogram was not overridden due to incorrect mode of its
18950 first parameter.
18951 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18952 synchronized private extension declarations. Verify that the ancestor is
18953 a limited or synchronized interface or in the generic case, the ancestor
18954 is a tagged limited type or synchronized interface and all progenitors
18955 are either limited or synchronized interfaces.
18956 Derived_Type_Declaration): Check for presence of private extension when
18957 dealing with synchronized formal derived types.
18958 Process_Full_View): Enchance the check done on the usage of "limited" by
18959 testing whether the private view is synchronized.
18960 Verify that a synchronized private view is completed by a protected or
18961 task type.
18962 (OK_For_Limited_Init_In_05): New function.
18963 (Analyze_Object_Declaration): Move check for limited types later,
18964 because OK_For_Limited_Init requires its argument to have been resolved.
18965 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18966 in order to alleviate the upward compatibility introduced by AI-318.
18967 (Constrain_Corresponding_Record): If the constraint is for a component
18968 subtype, mark the itype as frozen, to avoid out-of-scope references to
18969 discriminants in the back-end.
18970 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18971 this subprogram against wrong sources.
18972 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18973 discriminant of limited type completed with a protected type, when the
18974 discriminant is used to constrain a private component of the type, and
18975 expansion is disabled.
18976 (Find_Type_Of_Object): Do not treat a return subtype that is an
18977 anonymous subtype as a local_anonymous_type, because its accessibility
18978 level is the return type of the enclosing function.
18979 (Check_Initialization): In -gnatg mode, turn the error "cannot
18980 initialize entities of limited type" into a warning.
18981 (OK_For_Limited_Init): Return true for generated nodes, since it
18982 sometimes violates the legality rules.
18983 (Make_Incomplete_Declaration): If the type for which an incomplete
18984 declaration is created happens to be the currently visible entity,
18985 preserve the homonym chain when removing it from visibility.
18986 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18987 inherited subprograms.
18988 (Access_Definition): If this is an access to function that is the return
18989 type of an access_to_function definition, context is a type declaration
18990 and the scope of the anonymous type is the current one.
18991 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18992 incomplete subtype to the set of private dependents of the original
18993 incomplete type.
18994 (Constrain_Discriminated_Type): Emit an error message whenever an
18995 incomplete subtype is being constrained.
18996 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18997 corresponding subtype of the full view of the original incomplete type.
18998 (Check_Incomplete): Properly detect invalid usage of incomplete types
18999 and subtypes.

19013
19014 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
19015 handling executable extension manually and duplicating code.
19016
19017 * make.adb: Implement new -S switch
19018 (Gnatmake): Use new function Osint.Executable_Name instead
19019 of handling executable extension manually.
19020
19021 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
19022 is specified, the executable name ends with this suffix.
19023 Take advantage of Osint.Executable_Name instead of duplicating code.
19024

190342006-10-31 Vincent Celier <celier@adacore.com>
19035
19036 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
19037 call it with -static-libgcc, as there are some platforms, such as
19038 Darwin, where one of these two switches is compulsory to link.
19039

6f7f72f9 19041
70198b9f
AC		 19042 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
19043 instead of ADA_PROJECT_PATH, for the project path.
19044 (Gnatls): When displaying the project path directories, use host dir
19045 specs.
19046
19047 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
19048 names in the project path, as absolute paths may correspond to
19049 multi-valued VMS logical names.
19050
190512006-10-31 Vincent Celier <celier@adacore.com>
19052
19053 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
19054 absolute path name.

19056 (Change_Dir): Remove, no longer used
19057 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
19058 on Windows. Get it calling Get_Current_Dir.

190632006-10-31 Thomas Quinot <quinot@adacore.com>
19064
19065 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
19066 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
19067 to No_Socket.
19068 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
19069 W_Sig_Socket.

6f7f72f9
EB		 19082 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
19083 variant records
19084 (Layout_Variant_Record): Retrieve the discriminants from the entity
70198b9f
AC		 19085 rather than from the type definition, because in the case of a full
19086 type for a private type we need to take the discriminants from the
19087 partial view.
6f7f72f9
EB		 19088 (Layout_Component_List): When applying the Max operator to variants with
19089 a nonstatic size, check whether either operand is static and scale that
19090 operand from bits to storage units before applying Max.
70198b9f
AC		 19091 (Layout_Type): In VMS, if a C-convention access type has no explicit
19092 size clause (and does not inherit one in the case of a derived type),
19093 then the size is reset to 32 from 64.
19094
190952006-10-31 Vincent Celier <celier@adacore.com>
19096
19097 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
19098 its file has already been loaded, according to the unit being loaded,
19099 not to the current value of Multiple_Unit_Index.
19100
191012006-10-31 Thomas Quinot <quinot@adacore.com>
19102 Eric Botcazou <ebotcazou@adacore.com>
19103 Arnaud Charlet <charlet@adacore.com>
19104

19109 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
19110 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
19111 a-calend-mingw.adb version.
19112
6f7f72f9 19113 * Makefile.rtl: Added s-dsaser.
70198b9f
AC		 19114 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
19115 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
19116 Ada.Dispatching.Round_Robin.
19117 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
19118
19119 * Make-lang.in: Remove all references to gt-ada-decl.h.
19120 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
19121 sources.
19122 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
19123 Update dependencies.
19124
19125 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
19126
191272006-10-31 Vincent Celier <celier@adacore.com>
19128
19129 * mlib-utl.adb (Initialized): Remove, no longer used
19130 (Initialize): Remove, no longer used
19131 (Ar): If Ar_Exec is null, get the location of the archive builder and,
19132 if there is one, the archive indexer. Fail if the archive builder cannot
19133 be found.
19134 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
19135 be found.
19136
191372006-10-31 Ed Schonberg <schonberg@adacore.com>
19138
19139 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
19140 Process_Body_Clauses): If the context of a body includes a use clause
19141 for P.Q then a with_clause for P in the same body is not redundant,
19142 even if the spec also has a with_clause on P.
19143 Add missing continuation mark to error msg
19144 (Build_Limited_Views): A limited view of a type is tagged if its
19145 declaration includes a record extension.
19146 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
19147 node, even if the subunit has errors. This avoids malfunction by
19148 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
19149 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
19150 generation of obsolescent messages for with statements (cannot do
19151 this too early, or we cannot implement avoiding the messages in the
19152 case of obsolescent units withing obsolescent units).
19153 (Install_Siblings): If the with_clause is on a remote descendant of
19154 an ancestor of the current compilation unit, find whether there is
19155 a sibling child unit that is immediately visible.
19156 (Remove_Private_With_Clauses): New procedure, invoked after completing
19157 the analysis of the private part of a nested package, to remove from
19158 visibility the private with_clauses of the enclosing package
19159 declaration.
19160 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
19161 now centralized in Generate_Reference.
19162 (Install_Limited_Context_Clauses): Remove superfluous error
19163 message associated with unlimited view visible through use
19164 and renamings. In addition, at the point in which the error
19165 is reported, we add the backslash to the text of the error
19166 to ensure that it is reported as a single error message.
19167 Use new // insertion for some continuation messages
19168 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
19169 to create implicit with_clause for parent unit mentioned in original
19170 limited_with_clause.
19171 (Install_Limited_With_Unit): Set entity of parent identifiers if the
19172 unit is a child unit. For ASIS queries.
19173 (Analyze_Subunit): If the subunit appears within a child unit, make all
19174 ancestor child units directly visible again.
19175

19186 Add the new actual Abstract_Present to every call to
19187 P_Interface_Type_Definition.
19188 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
19189 a formal object declaration with an access definition or a subtype mark
19190 with a null exclusion.
19191 (P_Generic_Association): Handle association with box, and others_choice
19192 with box, to support Ada 2005 partially parametrized formal packages.

AC		 19197 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
19198 (P_Type_Declaration): Remove barrier against the reserved word "limited"
19199 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
19200 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
19201 private extensions.
19202 (P_Type_Declaration): Add the new actual Abstract_Present to every call
19203 to P_Interface_Type_Definition.
19204 (P_Interface_Type_Definition): Addition of one formal to report an error
19205 if the reserved word abstract has been previously found.
19206 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
19207 object renaming declaration with an access definition or subtype mark
19208 with a possible null exclusion.
19209
19210 * par-ch9.adb: Minor error msg fix
19211
19212 * par-load.adb: Add missing continuation mark to error msg
19213

192162006-10-31 Vincent Celier <celier@adacore.com>
19217
19218 * prj-dect.adb (Parse_Attribute_Declaration): Do not issue warning for
19219 unknown attribute in unknown package or in package that does not need
19220 to be checked.
19221 (Parse_Package_Declaration): Do not issue warning for unknown package in
19222 quiet output.
19223
192242006-10-31 Vincent Celier <celier@adacore.com>
19225
19226 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
19227 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
19228 Packages_To_Check.
19229
192302006-10-31 Vincent Celier <celier@adacore.com>
19231
19232 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
19233 on VMS, change "__" to '.' before checking the name.
19234 (Record_Ada_Source): Always add the source file name in the list of
19235 of sources, even if it is not the first time, as it is for another
19236 source index.
19237 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
19238 dot, instead of replacing only the first '_'.
19239
19240 * prj-part.adb (Parse): Convert project file path to canonical form
19241
19242 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
19243 extended, the project id of the project extending it is recorded in its
19244 data, even when it has already been processed as an imported project.
19245
192462006-10-31 Robert Dewar <dewar@adacore.com>
19247
19248 * repinfo.adb (List_Entities): Don't list entities from renaming

19252 Robert Dewar <dewar@adacore.com>
19253
19254 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
19255 only a restriction warning is active for the given restriction. This is
19256 desirable because we do not want to modify code in the case where only
19257 a warning is set.
19258 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
19259 causes overriding of real restrictions.
19260 Take advantage of new No_Restrictions constant.
19261
19262 * raise.h: (__gnat_set_globals): Change profile.
19263

19270 Move all the entities in obsolete package System.PolyORB_Interface to
19271 System.Partition_Interface.
70198b9f
AC		 19272 (RE_Storage_Size): New function in System.Tasking.
19273 (RE_Get_Ceiling): New entity.
19274 (RE_Set_Ceiling): New entity.
19275 (RO_PE_Get_Ceiling): New entity.
19276 (RO_RE_Set_Ceiling): New entity.

19287 Gary Dismukes <dismukes@adacore.com>
19288
19289 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
19290 properly an attempt to apply Unchecked_Access to a protected operation.
19291 (OK_Self_Reference): New subprogram to check the legality of an access
19292 attribute whose prefix is the type of an enclosing aggregate.
19293 Generalizes previous mechanism to handle attribute references nested
19294 arbitrarily deep within the aggregate.
19295 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19296 can appear in an aggregate if this is a default-initialized aggregate
19297 for a self-referential type.
19298 (Resolve_Attribute, case Access): Ditto.
19299 Add support for new implementation defined attribute Stub_Type.
19300 (Eval_Attribute, case Attribute_Stub_Type): New case.
19301 (Analyze_Attribute, case Attribute_Stub_Type): New case.
19302 (Stream_Attribute_Available): Implement using new subprogram from
19303 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
19304 Has_Specified_Stream_Attribute flag.
19305 Disallow Storage_Size and Storage_Pool for access to subprogram
19306 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19307 access types of return subtypes in extended return statements. Remove
19308 accessibility checks on anonymous access types when Unchecked_Access is
19309 used.
19310 (Analyze_Attribute): Add support for the use of 'Class to convert
19311 a class-wide interface to a tagged type.
19312 Add support for the attribute Priority.
19313 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19314 whether the designated type is discriminated with a constrained partial
19315 view and require static matching in that case.
19316 Add local variable Des_Btyp. The Designated_Type
19317 of an access to incomplete subtype is either its non-limited view if
19318 coming from a limited with or its etype if regular incomplete subtype.
19319
19320 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19321 Fix predicate to identify and allow cases of (expander-generated)
19322 references to tag of designated object of a RACW.
19323 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19324 non-static, and therefore cannot appear as a primary in a preelaborable
19325 package.
19326 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
19327 Has_Read_Write_Attributes.
19328 (Has_Read_Write_Attributes): Reimplement in termes of
19329 Has_Stream_Attribute_Definition.
19330 (Missing_Read_Write_Attributes): When checking component types in a
19331 record, unconditionally call Missing_Read_Write_Attributes recursively
19332 (remove guard checking for Is_Record_Type / Is_Access_Type).
19333
193342006-10-31 Robert Dewar <dewar@adacore.com>
19335
19336 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
19337 useless assignments here and conditionalize it on absence of exception
19338 handlers.
19339 (Analyze_Exception_Handlers): Small code reorganization of error
19340 detection code, for new handling of formal packages.
19341

6f7f72f9
EB		 19344
19345 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
70198b9f
AC		 19346 that has been constant-folded, preserve information of original tree,
19347 for ASIS uses.
19348 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
19349 generated private extension declaration if the formal derived type is
19350 synchronized. Carry synchronized present over to the generated private
19351 extension.
19352 (Validate_Derived_Type_Instance): Ensure that the actual of a
19353 synchronized formal derived type is a synchronized tagged type.
19354 (Instantiate_Formal_Package): When creating the instantiation used to
19355 validate the actual package of a formal declared without a box, check
19356 whether the formal itself depends on a prior actual.
19357 (Instantiate_Formal_Subprogram): Create new entities for the defining
19358 identifiers of the formals in the renaming declaration, for ASIS use.
19359 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19360 a renaming declaration or a subtype declaration for an actual in an
19361 instance, capture location information of declaration in generic, for
19362 ASIS use.
19363 (Instantiate_Formal_Package): Add comments on needed additional tests.
19364 AI-317 (partial parametrization) is fully implemented.
19365 (Validate_Private_Type_Instance): Add check for actual which
19366 must have preelaborable initialization
19367 Use new // insertion for some continuation messages
19368 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19369 Default_Expression. Add type retrieval when the declaration has an
19370 access definition. Update premature usage of incomplete type check.
19371 (Check_Access_Definition): New subsidiary routine. Check whether the
19372 current compilation version is Ada 05 and the supplied node has an
19373 access definition.
19374 (Instantiate object): Alphabetize local variables. Handle the creation
19375 of new renaming declarations with respect to the kind of definition
19376 used - either an access definition or a subtype mark. Guard against
19377 unnecessary error message in the context of anonymous access types after
19378 they have been resolved. Add check for required null exclusion in a
19379 formal object declaration.
19380 (Switch_View): A private subtype of a non-private type needs to be
19381 switched (the base type can have been switched without its private
19382 dependents because of the last branch of Check_Private_View.
19383 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19384 value from BT.
19385 (Instantiate_Type): Emit an error message whenever a class-wide type of
19386 a tagged incomplete type is used as a generic actual.
19387 (Find_Actual_Type): Extend routine to handle a component type in a child
19388 unit that is imported from a formal package in a parent.
19389 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19390 agree on constrainedness, rather than checking against ultimate ancestor
19391 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19392 generic body, for navigation purposes.
19393

19395 Thomas Quinot <quinot@adacore.com>
19396
19397 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
19398 type.
19399 (New_Stream_Subprogram): When processing an attribute definition clause
19400 for a stream-oriented subprogram, record an entity node occurring at
19401 the point of clause to use for checking the visibility of the clause,
19402 as defined by 8.3(23) as amended by AI-195.
19403 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19404 New_Stream_Function and New_Stream_Procedure.
19405 (New_Stream_Function, New_Stream_Procedure): Removed.
19406 (Analyze_Attribute_Definition_Clause, case Address): Check new
19407 Alignment_Check check

19411 Robert Dewar <dewar@adacore.com>
19412
19413 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19414 generate the same errors compiling under -gnatc.
19415 (Try_Object_Operation): If no candidate interpretation succeeds, but
19416 there is at least one primitive operation with the right name, report
19417 error in call rather than on a malformed selected component.
19418 (Analyze_Selected_Component): If the prefix is an incomplete type from
19419 a limited view, and the full view is available, use the full view to
19420 determine whether this is a prefixed call to a primitive operation.
19421 (Operator_Check): Verify that a candidate interpretation is a binary
19422 operation before checking the type of its second formal.
19423 (Analyze_Call): Add additional warnings for function call contexts not
19424 yet supported.
19425 (Analyze_Allocator): Move the check for "initialization not allowed for
19426 limited types" after analyzing the expression. This is necessary,
19427 because OK_For_Limited_Init looks at the structure of the expression.
19428 Before analysis, we don't necessarily know what sort of expression it
19429 is. For example, we don't know whether F(X) is a function call or an
19430 indexed component; the former is legal in Ada 2005; the latter is not.
19431 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19432 were missing. We also didn't handle qualified expressions. Now also
19433 allow function calls. Use new common routine OK_For_Limited_Init.
19434 (Analyze_Type_Conversion): Do not perform some legality checks in an
19435 instance, because the error message will be redundant or spurious.
19436 (Analyze_Overloaded_Selected_Component): Do not do style check when
19437 setting an entity, since we do not know it is the right entity yet.
19438 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19439 (Analyze_Overloaded_Selected_Component): Same change
19440 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19441 since regular incomplete subtypes are transformed into corresponding
19442 subtypes of their full views.
19443 (Complete_Object_Operation): Treat name of transformed subprogram call
19444 as coming from source, for browsing purposes.
19445 (Try_Primitive_Operation): If formal is an access parameter, compare
19446 with base type of object to determine whether it is a primitive
19447 operation.
19448 (Operator_Check): If no interpretation of the operator matches, check
19449 whether a use clause on any candidate might make the operation legal.
19450 (Try_Class_Wide_Operation): Check whether the first parameter is an
19451 access type whose designated type is class-wide.

19458 warn on infinite loops.
19459 Add \\ to some continuation messages
19460 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19461 (Process_Bounds): If the bounds are integer literals that result from
19462 constant-folding, and they carry a user-defined type, preserve that type
19463 rather than treating this as an integer range.
19464 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
19465 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.

19473 or AND THEN for possible tracking.
19474 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
19475 case of while loops so we can track values in the loop body.

70198b9f
AC		 19481 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19482 procedure cannot be a protected operation (it is a basic_declaration,
19483 not a subprogram_declaration).
19484 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19485 Subp. Add logic for entry processing.
19486 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
19487 Determine whether an entry or subprogram of a protected or task type
19488 override an inherited primitive of an implemented interface.
19489 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
19490 Update the actual used in calls to Check_Overriding_Indicator.

19498 Extra_Formals field.
19499 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19500 pass new parameters. Add support for adding the new extra access formal
19501 for functions whose calls are treated as build-in-place.
19502 (Analyze_A_Return_Statement): Correct casing in error message.
19503 Move Pop_Scope to after Analyze_Function_Return, because an extended
19504 return statement really is a full-fledged scope. Otherwise, visibility
19505 doesn't work right. Correct use of "\" for continuation messages.
19506 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19507 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19508 the node doesn't get properly marked as analyzed.
19509 (Analyze_Subprogram_Body): If subprogram is a function that returns
19510 an anonymous access type that denotes a task, build a Master Entity
19511 for it.
19512 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19513 proper usage of null exclusion in a result definition.
19514 (Process_Formals): Code cleanup and new error message.
19515 (Process_Formals): Detect incorrect application of null exclusion to
19516 non-access types.
19517 (Conforming_Types): Handle conformance between [sub]types and itypes
19518 generated for entities that have null exclusions applied to them.
19519 (Maybe_Primitive_Operation): Add an additional type retrieval when the
19520 base type is an access subtype. This case arrises with null exclusions.
19521 (New_Overloaded_Entity): Do not remove the overriden entity from the
19522 homonym chain if it corresponds with an abstract interface primitive.
19523 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19524 call to the synthesized predicate Is_Incomplete_Type.
19525 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19526 primitives.
19527 (Analyze_Subprogram_Declaration): Check that abstract interface
19528 primitives are abstract or null.
19529 (Analyze_Subprogram_Specification): Remove previous check for abstract
19530 interfaces because it was not complete.

19536 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
19537 of Analyze_Package_Body, to create Itype references for anonymous
19538 access types created in the package declaration, whose designated types
19539 may have only a limited view.
19540 (Analyze_Package_Specification): For the private part of a nested
19541 package, install private_with_clauses of enclosing compilation unit if
19542 we are in its visible part.
19543 (Declare_Inherited_Private_Subprograms): Complete barrier
19544 to ensure that the primitive operation has an alias to some parent
19545 primitive. This is now required because, after the changes done for the
19546 implementation of abstract interfaces, the contents of the list of
19547 primitives has entities whose alias attribute references entities of
19548 such list of primitives.
19549 (Analyze_Package_Specification): Simplify code that handles parent units
19550 of instances and formal packages.
19551 (Uninstall_Declarations): Check the convention consistency among
19552 primitive overriding operations of a tagged record type.

19567 (Find_Type): Handle the case of an attribute reference for
19568 implementation defined attribute Stub_Type (simply let the analysis of

19577 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19578 in a formal object declaration or in a subtype declaration.
19579 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19580 (Check_Null_Exclusion): New local routine to
19581 Analyze_Subprogram_Renaming. Check whether the formals and return
19582 profile of a renamed subprogram have required null exclusions when
19583 their counterparts of the renaming already impose them.
19584 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19585 Determine whether an entity is inside a generic scope.
19586 (In_Open_Scope): First pass of documentation update.

19597 (Analyze_Task_Definition): Ditto.
19598 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19599 (Check_Overriding_Indicator): To find overridden interface operation,
19600 examine only homonyms that have an explicit subprogram declaration, not
19601 inherited operations created by an unrelated type derivation.
19602 (Check_Overriding_Indicator): When checking for the presence of "null"
19603 in a procedure, ensure that the queried node is a procedure
19604 specification.
19605 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
19606 type when the formal is an access to variable.
19607 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19608 (Analyze_Task_Type): Same addition

19623 that covers abstract interface subprograms we register it in all the
19624 secondary dispatch tables associated with abstract interfaces.
19625 (Check_Dispatching_Call): Add check that a dispatching call is not made
19626 to a function with a controlling result of a limited type. This is a
19627 current implementation restriction.
19628 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
19629 (Check_Dispatching_Operation): Do no emit a warning if the controlling

19631 (Is_Interface_Subprogram): Removed.
19632 (Check_Dispatching_Operation): If the subprogram is not a dispatching

19657 the context of generic instantiation.
19658 (Covers/Interface_Present_In_Ancestors): Use the base type to manage

19675 (Unqualify): New function for removing zero or more levels of
19676 qualification from an expression. There are numerous places where this
19677 ought to be used, but we currently only deal properly with zero or one
19678 level.
19679 (In_Instance); The analysis of the actuals in the instantiation of a

19703 (Has_Compatible_Alignment): New function
19704 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
19705 objects to handle the Ada 2005 case, where aliasedness no longer implies

19766 extended_return_statement nonterminal. Needed because all the necessary
19767 fields won't fit in N_Extended_Return_Statement.
19768 Generic_associations now carry the Box_Present flag, to indicate a

21160 (Is_Limited_Type): A type whose ancestor is an interface is limited if
21161 explicitly declared limited.
21162 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
21163 entities. Only used for component marked Is_Tag. If present it stores

21165 whose ancestor has discriminants.

21192 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
21193 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
21194 does not exist in the Ada RM.
21195 (Compatible_Int_Bounds): Determine whether two integer range bounds

21197 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
21198 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
21199 aggregate when it is part of an object declaration.

21202 constraints of the ancestor by retrieving them from the
21203 stored_constraint of the parent.

21210 Max/Min attributes now violate Restriction No_Implicit_Conditionals
21211

21220 availability of RE_Interface_Tag.
21221 (Build_Initialization_Call): Fix wrong access to the discriminant value.
21222 (Freeze_Record_Type): Do not generate the tables associated with
21223 timed and conditional dispatching calls through synchronized
21224 interfaces if compiling under No_Dispatching_Calls restriction.
21225 When compiling for Ada 2005, for a nonabstract
21226 type with a null extension, call Make_Controlling_Function_Wrappers
21227 and insert the wrapper function declarations and bodies (the latter
21228 being appended as freeze actions).
21229 (Predefined_Primitive_Bodies): Do not generate the bodies of the
21230 predefined primitives associated with timed and conditional
21231 dispatching calls through synchronized interfaces if we are
21232 compiling under No_Dispatching_Calls.
21233 (Build_Init_Procedure): Use RTE_Available to check if a run-time
21234 service is available before generating a call.
21235 (Make_Controlling_Function_Wrappers): New procedure.
21236 (Expand_N_Full_Type_Declaration): Create a class-wide master for
21237 access-to-limited-interfaces because they can be used to reference
21238 tasks that implement such limited interface.
21239 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
21240 procedure spec and body of the Offset_To_Top function that is generated
21241 when the parent of a type with discriminants has secondary dispatch
21242 tables.
21243 (Init_Secondary_Tags): Handle the case in which the parent of the type
21244 containing secondary dispatch tables has discriminants to generate the
21245 correct arguments to call Set_Offset_To_Top.
21246 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
21247
21248 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
21249 Add Wide_[Wide_]Expanded_Name.
21250 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
21251 the same functionality of Get_Prim_Op_Address but applied to predefined
21252 primitive operations because the pointers to the predefined primitives
21253 are now saved in a separate table.
21254 (Parent_Size): Modified to get access to the separate table of primitive
21255 operations or the parent type.
21256 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
21257 functionality of Set_Prim_Op_Address but applied to predefined primitive
21258 operations.
21259 (Set_Signature): New subprogram used to store the signature of a DT.
21260 (Displace): If the Offset_To_Top value is not static then call the
21261 function generated by the expander to get such value; otherwise use
21262 the value stored in the table of interfaces.
21263 (Offset_To_Top): The type of the actual has been changed to Address to
21264 give the correct support to tagged types with discriminants. In this
21265 case this value is stored just immediately after the tag field.
21266 (Set_Offset_To_Top): Two new formals have been added to indicate if the
21267 offset_to_top value is static and hence pass this value to the run-time
21268 to store it in the table of interfaces, or else if this value is dynamic
21269 and then pass to the run-time the address of a function that is
21270 generated by the expander to provide this value for each object of the
21271 type.
21272
21273 * rtsfind.ads (Default_Prin_Op_Count): Removed.
21274 (Default_Prim_Op_Count): New entity
21275 (Get_Predefined_Prim_Op_Address): New entity
21276 (Set_Predefined_Prim_Op_Address): New entity

21282 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
21283 Make_Adjust_Call done for a newly-allocated object.
21284
21285 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
21286 in a subprogram are wrapped in a cleanup block, indicate that the
21287 subprogram contains an inner block with an exception handler.
21288 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
21289 Adjust call is for a newly-allocated object. In that case we must not
21290 assume that the finalization list chain pointers are correct (since they
21291 come from a bit-for-bit copy of the original object's pointers) so if
21292 the attach level would otherwise be zero (no change), we set it to 4
21293 instead to cause the pointers to be reset to null.
21294
21295 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
21296 reset chain pointers to null.
21297
212982006-02-13 Ed Schonberg <schonberg@adacore.com>
21299
21300 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
21301 string, and the context requires a loop for the assignment (e.g.
21302 because the left-hand side is packed), generate a unique name for the
21303 temporary that holds the string, to prevent spurious name clashes.

21310 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21311 return unconstrained arrays.
21312 Update comments.
21313 (Expand_Call): An indirect call through an access parameter of a
21314 protected operation is not a protected call.
21315 Add circuit to raise CE in Ada 2005 mode following call
21316 to Raise_Exception.
21317 (Register_DT_Entry): Do nothing if
21318 the run-time does not give support to abstract interfaces.
21319 (Freeze_Subprogram): In case of dispatching operations, do not generate
21320 code to register the operation in the dispatch table if the source
21321 is compiled with No_Dispatching_Calls.
21322 (Register_Predefined_DT_Entry): Generate code that calls the new
21323 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21324 Set_Prim_Op_Address.
21325
21326 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21327 on array assignments if the right-hand side is a function call that has
21328 been inlined. Check is performed on the assignment in the block.
21329 (Process_Bounds): If bounds and range are overloaded, apply preference
21330 rule for root operations to disambiguate, and diagnose true ambiguity.
21331 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21332 a tag-indeterminate right-hand side even when Expander_Active is True.
21333 Needed to ensure that dispatching calls to T'Input are allowed and
21334 get the tag of the target class-wide object.
21335
21336 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21337 an inherited primitive operation that already overrides several
21338 abstract interface primitives. For transitivity, the new entity must
21339 also override all the abstract interface primitives covered by the
21340 inherited overriden primitive.
21341 Emit warning if new entity differs from homograph in same scope only in
21342 that one has an access parameter and the other one has a parameter of
21343 a general access type with the same designated type, at the same
21344 position in the signature.
21345 (Make_Inequality_Operator): Use source locations of parameters and
21346 subtype marks from corresponding equality operator when creating the
21347 tree structure for the implicit declaration of "/=". This does not
21348 change anything in behaviour except that the decoration of the
21349 components of the subtree created for "/=" allows ASIS to get the
21350 string images of the corresponding identifiers.
21351 (Analyze_Return_Statement): Remove '!' in warning message.
21352 (Check_Statement_Sequence): Likewise.
21353 (Analyze_Subprogram_Body): For an access parameter whose designated type
21354 is an incomplete type imported through a limited_with clause, use the
21355 type of the corresponding formal in the body.
21356 (Check_Returns): Implicit return in No_Return procedure now raises
21357 Program_Error with a compile time warning, instead of beging illegal.
21358 (Has_Single_Return): Function returning unconstrained type cannot be
21359 inlined if expression in unique return statement is not an identifier.
21360 (Build_Body_To_Inline): It is possible to inline a function call that
21361 returns an unconstrained type if all return statements in the function
21362 return the same local variable. Subsidiary procedure Has_Single_Return
21363 verifies that the body conforms to this restriction.
21364
21365 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21366 same type, and one of them is of an anonymous access type, convert
21367 the other operand to it, so that this is a valid binary operation for
21368 gigi.
21369 (Resolve_Type_Conversion): Handle subtypes of protected types and
21370 task types when accessing to the corresponding record type.
21371 (Resolve_Allocator): Add '\' in 2-line warning message.
21372 Remove '!' in warning message.
21373 (Resolve_Call): Add '\' in 2-line warning message.
21374 (Valid_Conversion): Likewise.
21375 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21376 resulting type may be an access type with an implicit dereference.
21377 Obtain the proper component from the designated type.
21378 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21379 given by an expanded name with prefix Standard, when the operands are
21380 of an anonymous access type.
21381 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21382 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21383 prefix of the expression is not of an incomplete type. Allows full
21384 diagnoses of all semantic errors.
21385 (Resolve_Actuals): If the actual is an allocator whose directly
21386 designated type is a class-wide interface we build an anonymous
21387 access type to use it as the type of the allocator. Later, when
21388 the subprogram call is expanded, if the interface has a secondary
21389 dispatch table the expander will add a type conversion to force
21390 the displacement of the pointer.
21391 (Resolve_Call): If a function that returns an unconstrained type is
21392 marked Inlined_Always and inlined, the call will be inlined and does
21393 not require the creation of a transient scope.
21394 (Check_Direct_Boolean_Op): Removed
21395 (Resolve_Comparison_Op): Remove call to above
21396 (Resolve_Equality_Op): Remove call to above
21397 (Resolve_Logical_Op): Inline above, since this is only call.
21398 (Valid_Conversion): Handle properly conversions between arrays of
21399 convertible anonymous access types.

21420 class-wide type then we use it directly.
21421 Check No_Dispatching_Calls restriction.
21422 (Default_Prim_Op_Position): Remove the code that looks for the last
21423 entity in the list of aliased subprograms. This code was wrong in
21424 case of renamings.
21425 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21426 when the source is compiled with the No_Dispatching_Calls restriction.

21428 if we are compiling with restriction No_Dispatching_Calls.
21429 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21430 subprograms if we are compiling under No_Dispatching_Calls restriction.
21431 (Make_DT): Generate a dispatch table with a single dummy entry if
21432 we are compiling with the No_Dispatching_Calls restriction. In
21433 addition, in this case we don't generate code that calls to the
21434 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21435 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21436 of this subprogram if compiling with the No_Dispatching_Calls
21437 restriction.
21438 (Expand_Type_Conversion): Instead of using the actual parameter,
21439 the argument passed as parameter to the conversion function was
21440 erroneously referenced by the expander.
21441 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21442 Set_Predefined_Primitive_Op_Address and Set_Signature.
21443 (Expand_Dispatching_Call): Generate call to
21444 Get_Predefined_Prim_Op_Address for predefined primitives.
21445 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21446 predefined primitives.
21447 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21448 primitives we reserve one dummy entry to ensure that the tag does not
21449 point to some memory that is associated with some other object. In
21450 addition, remove all the old code that generated the assignments
21451 associated with the signature of the dispatch table and replace them
21452 by a call to the new subprogram Set_Signature.
21453 (Set_All_DT_Position): Change the algorithm because now we have a

21878 synchronized type without a corresponding record, return the type
21879 itself.

21883 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21884 if this is the full-declaration associated with a private declaration
21885 that implement interfaces, then the private type declaration must be
21886 limited.
21887 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21888 as aliased. The use of the 'access attribute is not available for such
21889 object (for this purpose the object should be explicitly marked as
21890 aliased, but being an anonymous type this is not possible).

21905 (Add_One_Interp): Do not add to the list of interpretations aliased
21906 entities corresponding with an abstract interface type that is an
21907 immediate ancestor of a tagged type; otherwise we have a dummy
21908 conflict between this entity and the aliased entity.
21909 (Disambiguate): The predefined equality on universal_access is not
21910 usable if there is a user-defined equality with the proper signature,
21911 declared in the same declarative part as the designated type.
21912 (Find_Unique_Type): The universal_access equality operator defined under
21913 AI-230 does not cover pool specific access types.
21914 (Covers): If one of the types is a generic actual subtype, check whether
21915 it matches the partial view of the other type.

21958 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21959 This prevents scanning leading blanks and sign twice.

22297 (Displace): New subprogram that displaces the pointer to the object
22298 to reference one of its secondary dispatch tables.
22299 (IW_Membership): Modified to use the new table of interfaces.
22300 (Inherit_TSD): Modified to use the new table of interfaces.
22301 (Register_Interface_Tag): Use the additional formal to fill the
22302 contents of the new table of interfaces.
22303 (Set_Interface_Table): New subprogram that stores in the TSD the
22304 pointer to the table of interfaces.

22319 in all the calls to Expand_Interface_Thunk. Instead of referencing the
22320 record component containing the tag of the secondary dispatch table we

22330 ensure that the interfaces implemented by the ancestors are placed
22331 at the header of the generated list.
22332 (Expand_Interface_Conversion): Handle the case in which the displacement
22333 associated with the interface conversion is not statically known. In
22334 this case we generate a call to the new run-time subprogram Displace.
22335 (Make_DT): Generate and fill the new table of interfaces.
22336 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
22337 Get_Tagged_Kind and Set_Tagged_Kind.
22338 (Tagged_Kind): New function that determines the tagged kind of a type
22339 with respect to limitedness and concurrency and returns a reference to
22340 RE_Tagged_Kind.

22361 RE_TK_Tagged, RE_TK_Task.
22362
22363 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22364 Init_Secondary_Tags_Internal to allow its use with interface types and
22365 also to generate the code for the new additional actual required
22366 by Set_Offset_To_Top.
22367 (Build_Init_Statements): In case of components associated with abstract
22368 interface types there is no need to generate a call to its IP.
22369 (Freeze_Record_Type): Generate Select Specific Data tables only for
22370 concurrent types.
22371 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
22372 the bodies and specifications of the predefined primitive operations
22373 dealing with dispatching selects and abort, 'Callable, 'Terminated only
22374 for concurrent types.

22518 component associated with the secondary table of an abstract interface
22519 type, return the entity associated with such abstract interface type.
22520 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
22521 base type to create anonymous subtype, because entity may be a locally
22522 declared subtype or generic actual.
22523 (Find_Interface): New subprogram that given a tagged type and one of its
22524 component associated with the secondary table of an abstract interface
22525 type, return the entity associated with such abstract interface type.
22526
22527 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
22528 conversion cannot be handled at compile time. In this case we pass this

22567 legal within a protected type that implements an interface.
22568 (Collect_Interfaces): Do not add to the list the interfaces that
22569 are implemented by the ancestors.
22570 (Derived_Type_Declaration): If the parent of the full-view is an
22571 interface perform a transformation of the tree to ensure that it has
22572 the same parent than the partial-view. This simplifies the job of the
22573 expander in order to generate the correct object layout, and it is
22574 needed because the list of interfaces of the full-view can be given in
22575 any order.
22576 (Process_Full_View): The parent of the full-view does not need to be
22577 a descendant of the parent of the partial view if both parents are
22578 interfaces.
22579 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22580 "limited" the parent must be a limited type.
22581 (Build_Derived_Record_Type): A derived type that is explicitly limited

22592 lists of interfaces constitute a set equality. If not, the first
22593 differing interface is returned.
22594 (Process_Full_View): Improve the check for the "no hidden interface"
22595 rule as defined by AI-396.

22602 that generates the references for primitive operations. This allows to
22603 remove an unnecessary exception handler.
22604 Code reformatting and comment clean ups.

226062005-12-09 Vincent Celier <celier@adacore.com>
22607
22608 * gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U
22609 If GNAT CHECK is called with a project file, but with no
22610 source on the command line, call gnatcheck with all the compilable
22611 sources of the project.
22612 Take into account the new command Check, for gnatcheck. Treat as for
22613 other ASIS tools: take into account project, specific package Check and

22653 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
22654 available user-specified stream attributes on limited parameters to
22655 also test the type directly rather than only its underlying type (for
22656 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22657 attributes are visible at the point of the subprogram declaration.
22658 For Ada 2005, the error message is modified to indicate that the
22659 type's stream attributes must be visible (again, only for -gnat05).

23120 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
23121 object with an address clause into an indirect reference, drop the
23122 initializing expression.
23123 Include "expr.h".
23124 (STACK_CHECK_BUILTIN): Delete.
23125 (STACK_CHECK_PROBE_INTERVAL): Likewise.

23132 related): For a prefix that is a dereference of a fat or thin pointer,
23133 if there is an actual subtype provided by the front-end, use that
23134 subtype to build an actual type with bounds template.
23135 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
23136 is provided by the front-end, use that subtype to compute the size of
23137 the deallocated object.
23138 (gnat_to_gnu): When adding a statement into an elaboration procedure,
23139 check for a potential violation of a No_Elaboration_Code restriction.
23140 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
23141 with extra arguments to control whether to recurse through non-values
23142 and to let the caller know if the stabilization has succeeded.

23144 maybe_stabilize, for common uses without restriction on lvalues and
23145 without need to check for the success indication.
23146 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
23147 pass false instead of 0 as the FORCE argument which is a bool.
23148 (Identifier_to_gnu): Remove checks ensuring that an renamed object
23149 attached to a renaming pointer has been properly stabilized, as no such
23150 object is attached otherwise.
23151 (call_to_gnu): Invoke create_var_decl to create the temporary when the
23152 function uses the "target pointer" return mechanism.
23153 Reinstate conversion of the actual to the type of the formal
23154 parameter before any other specific treatment based on the passing
23155 mechanism. This turns out to be necessary in order for PLACEHOLDER
23156 substitution to work properly when the latter type is unconstrained.

23169 from a fat or thin pointer type and a constrained object type.
23170 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
23171 types variants, and process special cases of VIEW_CONVERT expressions

23180 are converting back to its original type.
23181 (convert) <JM input>: Fallthrough regular conversion code instead of
23182 extracting the object if converting to a type variant.
23183 (create_var_decl): When a variable has an initializer requiring code
23184 generation and we are at the top level, check for a potential violation
23185 of a No_Elaboration_Code restriction.
23186 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
23187 SIZE and SIZE_UNIT which we need for later back-annotations.

23405 suppressed.
23406 (Expand_N_If_Statement): When killing a dead then-branch in an
23407 if-statement that has elsif_parts, recompute the Current_Value node

23462 attribute of the N_Free_Statement.
23463 Generate itype for classwide designated object in both cases of

23688 body.
23689 (Analyze_Package_Instantiation): Do not perform front-end inlining when
23690 the current context is itself an instance within a non-instance child
23691 unit, to prevent scope stack errors.
23692 (Save_References): If the node is an aggregate that is an actual in a
23693 call, rewrite as a qualified expression to preserve some type
23694 information, to resolve possible ambiguities in the instance.
23695 (Instance_Parent_Unit): New global variable to record the ultimate
23696 parent unit associated with a generic child unit instance (associated

23705 scope against package Standard. Add comments and a ??? comment.
23706 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible

23723 discriminant.
23724 (Build_Private_Derived_Type): The entity of the created full view of the
23725 derived type does not come from source. If after installing the private
23726 declarations of the parent scope the parent is still private, use its
23727 full view to construct the full declaration of the derived type.
23728 (Build_Derived_Record_Type): Relax the condition that controls the
23729 execution of the check that verifies that the partial view and

23740 Descendant to Find_Ancestor_Interface to leave the code more clear.
23741 Remove wrong code that avoids the generation of an error message
23742 when the immediate ancestor of the partial view is an interface.
23743 In addition some minor reorganization of the code has been done to
23744 leave it more clear.
23745 (Analyze_Type_Declaration): If type has previous incomplete tagged
23746 partial view, inherit properly its primitive operations.
23747 (Collect_Interfaces): Make public, for analysis of formal
23748 interfaces.

23750 formal interface declarations.
23751 (Build_Derived_Record_Type): Add support for private types to the code

23754 instance as well.
23755 (Access_Type_Declaration): Clean up declaration of malformed type
23756 declared as an access to its own classwide type, to prevent cascaded
23757 crash.
23758 (Collect_Interfaces): For private extensions and for derived task types
23759 and derived protected types, the parent may be an interface that must
23760 be included in the interface list.
23761 (Access_Definition): If the designated type is an interface that may
23762 contain tasks, create Master_Id for it before analyzing the expression
23763 of the declaration, which may be an allocator.
23764 (Record_Type_Declaration): Set properly the interface kind, for use
23765 in allocators, the creation of master id's for task interfaces, etc.

23770 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
23771 omitted in case of stream attribute subprograms.
23772 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
23773 appear immediately after a subprogram body, when there is no previous
23774 subprogram declaration.
23775 Change name Is_Package to Is_Package_Or_Generic_Package
23776 (Process_Formals): A non null qualifier on a non null named access
23777 type is not an error, and is a warning only if Redundant_Constructs
23778 are flagged.

23786 package instance of a generic child package.
23787 (Analyze_Package_Specification): When entering a private part of a
23788 package associated with a generic instance or formal package, the
23789 private declarations of the parent must be installed (by calling new
23790 procedure Install_Parent_Private_Declarations).
23791 Change name Is_Package to Is_Package_Or_Generic_Package
23792 (Preserve_Full_Attributes): For a synchronized type, the corresponding
23793 record is absent in a generic context, which does not indicate a
23794 compiler error.

23797
23798 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
23799 not try to rewrite a renamed stream attribute, because the operations
23800 on the type may not have been generated.
23801 Handle properly a renaming_as_body generated for a stream operation
23802 whose default is abstract because the object type itself is abstract.
23803 (Find_Type): If the type is incomplete and appears as the prefix of a
23804 'Class reference, it is tagged, and its list of primitive operations
23805 must be initialized properly.
23806 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23807 private declaration of a parent unit, prior to compiling the private
23808 part of a child unit, find on the scope stack the proper parent entity
23809 on which to link the use clause.
23810 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23811 detected.
23812 (Analyze_Object_Renaming): An attribute reference is not a legal object

23830 a procedure call is used as a select statement trigger and is not an
23831 entry renaming or a primitive of a limited interface.
23832 (Valid_Conversion): If the operand has a single interpretation do not
23833 remove address operations.
23834 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
23835 statement to inhibit warning.
23836 (Resolve_Unary_Op): Do not produce a warning when
23837 processing an expression of the form -(A mod B)
23838 Use Universal_Real instead of Long_Long_Float when we need a high

23840 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23841 (Resolve_Concatenation_Arg): Improve error message when argument is an
23842 ambiguous call to a function that returns an array.

24574 expanded in the code that returns the value of the displaced actual.
24575 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
24576 conversions that have no effect in the generated code because no
24577 displacement is required. Code cleanup; use local variables to

24939 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24940 syntax for anonymous access results.
24941 Replace Subtype_Mark field by Result_Definition in
24942 N_Function_Specification and N_Access_Definition specs.
24943 Add Null_Exclusion_Present to spec of N_Function_Specification.
24944 (Result_Definition): New function for N_Function_Specification and
24945 N_Access_Function_Definition.

24947 N_Access_Function_Definition.

24950 Result_Definition for cases of N_Access_Function_Definition and
24951 N_Function_Specification.
24952 Print "not null" if Null_Exclusion_Present on N_Function_Specification.

25025 the error location.
25026 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
25027 a function renaming thereof, is a valid prefix for 'Size (where it is
25028 intepreted as a function call).

25046 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
25047 become local to the whole package.
25048 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
25049 the package was already analyzed the new algorithm "replaces" the
25050 real entities by the shadow ones. This is required to ensure that
25051 the order of these entities in the homonym chains does not change;
25052 otherwise we can have undefined references at linking time because
25053 in case of conflicts the external name of the entities will have
25054 a suffix that depends on the order of the entities in the chain.
25055 (Remove_Limited_With_Clause): Complementary code that completes the
25056 new algorithm and replaces the shadow entities by the real ones.
25057 (Install_Limited_Withed_Unit): When unchaining entities before the
25058 installation of the shadow entities, only regular entities of the
25059 public part must be taken into account. This is required to
25060 keep this routine in synch with the work done by Remove_Limited_
25061 With_Clause
25062 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
25063 even if unit is analyzed, because the analysis of the unit is
25064 idempotent in any case, and the limited view of the unit may have to
25065 be installed for proper visibility.
25066 (Expand_Limited_With_Clause): Even if the unit in the implicit
25067 with_clause has been analyzed already, a limited view of the package
25068 must be built for the current context, if it does not exist yet.

25074 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
25075 defining entity for the instance body, make a new defining identifier
25076 rather than copying the entity of the spec, to prevent accidental
25077 sharing of the entity list.
25078 (Check_Private_View): When exchanging views of private types, build the
25079 list of exchanged views as a stack, to ensure that on exit the exchanges
25080 are undone in the proper order.
25081 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
25082 Restore the compilation environment in case of instantiation_error.
25083 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
25084 for an anonymous access result.
25085 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition

25098
25099 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
25100 underlying type
25101 to check if a type is Constrained in cases related to code generation
25102 (rather than semantic checking) since otherwise we do not generate
25103 similar code for mutable private types depending if their
25104 discriminants are visible or not.
25105 (Check_Abstract_Overriding): Do not complain about failure to override
25106 the primitive operations used in dispatching selects since they will
25107 always be overriden at the freeze point of the type.
25108 (Access_Definition): Separate out handling for resetting the scope
25109 of an anonymous access function result type. Retrieve the scope
25110 of the associated function rather than using Current_Scope, which
25111 does not have a consistent value (depends on whether we're in the
25112 middle of analyzing formal parameters). Add ??? comment about
25113 finding a cleaner way to handle the special cases of scope setting.
25114 (Process_Incomplete_Dependents): A protected operation is never a
25115 dispatching operation (only its wrapper may be).
25116 (Build_Derived_Record_Type): In case of tagged private types that
25117 implement interfaces add derivation of predefined primitive
25118 operations.
25119 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
25120 by two parameters that are used in case of derivation from abstract
25121 interface types: No_Predefined_Prims is used to avoid the derivation
25122 of predefined primitives from the interface, and Predefined
25123 Prims_Only is used to complete the derivation predefined primitives
25124 in case of private tagged types implementing interfaces.
25125 Fix typo in comments
25126 (Find_Interface_In_Descendant): Protect the frontend against
25127 wrong code with large circularity chains.
25128 (Is_Private_Overriding): Add support for entities overriding interface
25129 subprograms. The test failed because Entities associated with overriden
25130 interface subprograms are always marked as hidden (and used to build
25131 the secondary dispatch table); in this case the overriden entity is
25132 available through the field abstract_interface_alias (cf. override_
25133 dispatching_operation)
25134 (Access_Definition): Set the scope of the type to Current_Scope for the
25135 case of a function with an anonymous access result type.
25136 (Access_Subprogram_Declaration): Handle creation of the type entity for
25137 an access-to-function type with an anonymous access result.
25138 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
25139 in handling for N_Access_Function_Definition.
25140 (Analyze_Subtype_Declaration): Modify the text of error message.
25141 (Derived_Type_Declaration): Modify the text of error message.
25142 (Process_Subtype): Modify the text of error message plus cleanup
25143 of one redundant error message.
25144 (Analyze_Component_Declaration): Code cleanup.
25145 (Analyze_Object_Declaration): Code cleanup.
25146 (Analyze_Subtype_Declaration): Propagate the null-exclusion
25147 attribute in case of access types. Code cleanup.
25148 (Array_Type_Declaration): Code cleanup.
25149 (Process_Discriminants): Create the new null-excluding itype
25150 if required. Code cleanup.
25151 (Process_Subtype): Create the new null-excluding itype if
25152 required. Code cleanup.
25153 (Build_Derived_Record_Type): Code cleanup to avoid calling
25154 twice the subprogram derive_subprograms in case of private
25155 types that implement interfaces. In this particular case the
25156 subprogram Complete_Subprograms_Derivation already does the
25157 job associated with the second call.

25165
25166 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
25167 V (Obj.F), the rewriting does not involve the indexed component, but
25168 only the selected component itself.
25169 Do not apply the transformation if the analyzed node is an actual of a
25170 call to another subprogram.
25171 (Complete_Object_Operation): Retain the entity of the
25172 dispatching operation in the selector of the rewritten node. The
25173 entity will be used in the expansion of dispatching selects.
25174 (Analyze_One_Call): Improve location of the error message associated
25175 with interface.
25176 (Analyze_Selected_Component): No need to resolve prefix when it is a
25177 function call, resolution is done when parent node is resolved, as
25178 usual.
25179 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
25180 when attempting to resolve a call transformed from its object notation.
25181 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
25182 of the argument list for each interpretation of the operation.
25183 (Try_Object_Operation): The designated type of an access parameter may
25184 be an incomplete type obtained through a limited_with clause, in which
25185 case the primitive operations of the type are retrieved from its full
25186 view.
25187 (Analyze_Call): If this is an indirect call, and the return type of the
25188 access_to_subprogram is incomplete, use its full view if available.

25192
25193 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
25194 access types the null-exclusion and access-to-constant attributes must
25195 also match.
25196 (Analyze_Return_Statement): When the result type is an anonymous access
25197 type, apply a conversion of the return expression to the access type
25198 to ensure that appropriate accessibility checks are performed.
25199 (Analyze_Return_Type): For the case of an anonymous access result type,
25200 generate the Itype and set Is_Local_Anonymous_Access on the type.
25201 Add ??? placeholder for check to disallow returning a limited object
25202 in Ada 2005 unless it's an aggregate or a result of a function call.
25203 Change calls from Subtype_Mark to Result_Definition.
25204 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
25205 Result_Definition in call to Make_Function_Specification.
25206 (Build_Body_To_Inline): Change Set_Subtype_Mark to
25207 Set_Result_Definition.
25208 (Make_Inequality_Operator): Change formal Subtype_Mark to
25209 Result_Definition in call to Make_Function_Specification.
25210 (Process_Formals): Create the new null-excluding itype if required.
25211 (New_Overloaded_Entity): For an entity overriding an interface primitive
25212 check if the entity also covers other abstract subprograms in the same
25213 scope. This is required to handle the general case, that is, overriding
25214 other interface primitives and overriding abstract subprograms inherited
25215 from some abstract ancestor type.
25216 (New_Overloaded_Entity): For an overriding entity that comes from
25217 source, note the operation that it overrides.
25218 (Check_Conformance, Type_Conformant): Addition of one new formal
25219 to skip controlling formals in the analysis. This is used to
25220 handle overloading of abstract interfaces.
25221 (Base_Types_Match): Add missing case for types imported from
25222 limited-with clauses
25223 (New_Overloaded_Entity): Add barrier to protect the use of
25224 the "alias" attribute.

25229 verify that the procedure and the entry are mode conformant.
25230 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
25231 as a different operator, which is often a cut-and-paste error.

25235
25236 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
25237 used in controlling parameters exclude null because it is necessary to
25238 read the tag to dispatch, and null has no tag.
25239 (Override_Dispatching_Operation): If the previous operation is inherited
25240 from an interface, it becomes hidden and does not participate in later
25241 name resolution.

25245 Gary Dismukes <dismukes@adacore.com>
25246
25247 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
25248 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
25249 the expander will generate the corresponding run-time check to evaluate
25250 the expression.
25251 (Resolve_Call): Check for legal type of procedure name or prefix that
25252 appears as a trigger in a triggering alternative.
25253 (Valid_Conversion): If expression is ambiguous and the context involves
25254 an extension of System, remove System.Address interpretations.
25255 (Resolve_Qualified_Expression): Reject the case of a specific-type
25256 qualification applied to a class-wide argument. Enhance comment
25257 to explain checking of Original_Node.
25258 (Resolve_Type_Conversion): The location of the error message was not
25259 general enough to handle the general case and hence it has been removed.
25260 In addition, this patch improves the text of the message.
25261 (Resolve_Type_Conversion): Add missing support for access to interface
25262 types.
25263 (Resolve_Type_Conversion): If the target is a class-wide interface type,
25264 do not expand if the expression is the actual in a call, because proper
25265 expansion will take place when the call itself is expanded.
25266 (Resolve_Allocator): If the context is an unchecked conversion, the
25267 allocator inherits its storage pool, if any, from the target type of
25268 the conversion.

25272
25273 * sem_type.adb (Add_One_Interp): If a candidate operation is an
25274 inherited interface operation that has an implementation, use the
25275 implementation to avoid spurious ambiguities.
25276 (Interface_Present_In_Ancestor): In case of concurrent types we can't
25277 use the Corresponding_Record_Typ attribute to look for the interface
25278 because it is set by the expander (and hence it is not always
25279 available). For this reason we traverse the list of interfaces
25280 (available in the parent of the concurrent type).

25290 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
25291 of an entry.
25292 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25293 capture if it is generated in the second operand of a short-circuit
25294 operation.
25295 Do not capture values for variables with address clauses.
25296 (Is_Object_Reference): Treat a function call as an object reference only
25297 if its type is not Standard_Void_Type.

26083
26084 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
26085 longer protected objects. They have been replaced by lower-level
26086 suspension objects made up by a mutex and a condition variable (or
26087 their equivalent given a particular OS) plus some internal data to
26088 reflect the state of the suspension object.
26089 (Initialize, Finalize): Add this initialization procedure for
26090 Suspension_Object, which is a controlled type.
26091 (Finalize): Add the finalization procedure for Suspension_Object,
26092 which is a controlled type.
26093
26094 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
26095 Ada.Synchronous_Task_Control because there is no longer a need for a

26115 object to False.
26116 (Set_True): Add this procedure that sets the state of the suspension
26117 object to True, releasing the task that was suspended, if any.
26118 (Suspend_Until_True): Add this procedure that blocks the calling task
26119 until the state of the object is True. Program_Error is raised if
26120 another task is already waiting on that suspension object.
26121 (Initialize): Add this procedure for initializing the suspension
26122 object. It initializes the mutex and the condition variable which are
26123 used for synchronization and queuing, and it sets the internal state
26124 to False.
26125 (Finalize): Add this procedure for finalizing the suspension object,
26126 destroying the mutex and the condition variable.

26345 this subprogram implements a new algorithm that provides the
26346 same functionality and it is more clear in case of primitives
26347 associated with abstract interfaces.
26348 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
26349 clean up, the functionality of this subprogram is now provided

26363 the object to give access to the interface tag associated with the
26364 secondary dispatch table.
26365 (Expand_Interface_Thunk): New subprogram that generates the code of the
26366 thunk. This is required for compatibility with the C+ ABI.

26388 an access discriminant when the containing type is nonlimited.
26389 (Make_Incomplete_Type_Declaration): Create an incomplete type
26390 declaration for a record type that includes self-referential access
26391 components.
26392 (Check_Anonymous_Access_Types): Before full analysis of a record type
26393 declaration, create anonymous access types for each self-referential
26394 access component.
26395 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
26396 an access component in this context is a Local_Anonymous_Access, for
26397 proper accessibility checks.

26414 derivation if the derived type has an ancestor that is a formal type
26415 declared in the formal part of an enclosing generic.
26416 (Analyze_Object_Declaration): For protected objects, remove the check
26417 that they cannot contain interrupt handlers if not declared at library
26418 level.
26419 (Add_Interface_Tag_Components): New subprogram to add the tag components
26420 corresponding to all the abstract interface types implemented by a
26421 record type or a derived record type.

26431 if the discriminants of the designated type have defaults.
26432 (Access_Subprogram_Declaration): Associate the Itype node with the inner

26436 Derived_Type_Declaration, Find_Type_Name, Inherit_Components,
26437 Process_Full_View, Record_Type_Declaration): Modified to give
26438 support to abstract interface types
26439 (Derive_Subprograms): Addition of a new formal to indicate if
26440 we are in the case of an abstact-interface derivation
26441 (Find_Type_Of_Subtype_Indic): Moved from the body of the package
26442 to the specification because it is requied to analyze all the
26443 identifiers found in a list of interfaces
26444

26446
26447 * exp_ch3.adb: Implement config version of persistent_bss pragma
26448 (Check_Stream_Attributes): Use Stream_Attribute_Available instead of
26449 testing for TSS presence to properly enforce visibility rules.

26451 Make_Abstract_Interfaces_DT to generate the secondary tables
26452 associated with abstract interfaces.
26453 (Build_Init_Procedure): Modified to initialize all the tags
26454 corresponding.
26455 (Component_Needs_Simple_Initialization): Similar to other tags,

26465 misaligned because of packing or representation clauses.
26466 (Is_Legal_Copy): New predicate to determine whether a possibly
26467 misaligned in-out actual can actually be passed by copy/return. This
26468 is an error in case the type is by_reference, and a warning if this is
26469 the consequence of a DEC import pragma on the subprogram.
26470 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
26471 interface types
26472 (Expand_Inlined_Call): Mark temporary generated for the return value as
26473 internal, so that no useless scalar normalization is generated for it.
26474 (Expand_N_Subprogram_Declaration): Save unanalyzed body so calls to
26475 null procedure can always be inlined.
26476 (Expand_N_Subprogram_Declaration): If this is the declaration of a null
26477 procedure, generate an explicit empty body for it.
26478
26479 * exp_util.ads, exp_util.adb (Find_Interface_ADT): New subprogram.
26480 Given a type implementing an interface, returns the corresponding
26481 access_disp_table value.

26489 is a predefined primitive operation.
26490 (Expand_Subtype_From_Expr): If the expression is a selected component
26491 within an initialization procedure, compute its actual subtype, because
26492 the component may depend on the discriminants of the enclosing record.

da8f5fd9 26494 * i-cpp.ads, i-cpp.adb:
0adcdb66
AC		 26495 This package has been left available for compatibility with previous
26496 versions of the frontend. As part of the new layout this is now a
26497 dummy package that uses declarations available at a-tags.ads
26498
26499 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of
26500 "constant access" and "aliased [constant] access" when not compiling

26511 for a subprogram or instance declaration.
26512
26513 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Verify that an
26514 instantiation that is a dispatching operation has controlling access
26515 parameters that are null excluding.

26517 (Validate_Derived_Type_Instance): Add check for abstract interface
26518 types.

26520 the generic that is created to represent the formal package.
26521 (Analyze_Package_Instantiation): Instantiate body immediately if the
26522 package is a predefined unit that contains inlined subprograms, and
26523 we are compiling for a Configurable_Run_Time.

26528 error message condition, null procedures are correctly detected now.
26529 (New_Overloaded_Entity): Bypass trivial overriding indicator check
26530 for subprograms in the context of protected types. Instead, the
26531 indicator is examined in Sem_Ch9 while analysing the subprogram
26532 declaration.
26533 (Check_Overriding_Indicator): Check consistency of overriding indicator
26534 on subprogram stubs as well.
26535 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
26536 the library level.
26537 (Analize_Subprogram_Specification): When analyzing a subprogram in which
26538 the type of the first formal is a concurrent type, replace this type
26539 by the corresponding record type.
26540 (Analyze_Subprogram_Body): Undo the previous work.
26541 (Analyze_Procedure_Call): If the call has the form Object.Op, the
26542 analysis of the prefix ends up analyzing the call itself, after which
26543 we are done.
26544 (Has_Interface_Formals): New subprogram subsidiary to analyze
26545 subprogram_specification that returns true if some non
26546 class-wide interface subprogram is found
26547 (New_Overloaded_Entity): Modified to give support to abstract
26548 interface types
26549 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
26550 access to subprograms must be recursive.
26551 (Is_Unchecked_Conversion): Improve the test that recognizes
26552 instantiations of Unchecked_Conversion, and allows them in bodies that
26553 are to be inlined by the front-end. When the body comes from an
26554 instantiation, a reference to Unchecked_Conversion will be an
26555 Expanded_Name, even though the body has not been analyzed yet.

26566 * sem_disp.adb (Check_Controlling_Type): Give support to entities
26567 available through limited-with clauses.
26568 (Check_Dispatching_Operation): A stub acts like a body, and therefore is
26569 allowed as the last primitive of a tagged type if it has no previous
26570 spec.

26572 to give support to abstract interface types
26573
26574 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
26575 in the case where the target type is an anonymous access type of an
26576 object or component (that is, when Is_Local_Anonymous_Access is true).
26577 Prevent the special checks for conversions of access discriminants in
26578 the case where the discriminant belongs to a nonlimited type, since
26579 such discriminants have their accessibility level defined in the same
26580 way as a normal component of an anonymous access type.
26581 (Resolve_Allocator): When an allocator's designated type is a class-wide
26582 type, check that the accessibility level of type given in the

26595 (Resolve_Actuals): Enable full error reporting on view conversions
26596 between unrelated by_reference array types.
26597 The rule for view conversions of arrays with aliased components is
26598 weakened in Ada 2005.
26599 Call to obsolescent subprogram is now considered to be a violation of
26600 pragma Restrictions (No_Obsolescent_Features).
26601 (Check_Direct_Boolean_Operator): If the boolean operation has been
26602 constant-folded, there is nothing to check.
26603 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26604 check on possible violation of restriction No_Direct_Boolean_Operators
26605 until after expansion of operands, to prevent spurious errors when
26606 operation is constant-folded.

26615 prefix is a parameterless function that returns an access_to_procedure.
26616 (Transform_Object_Operation): Handle properly function calls of the
26617 form Obj.Op (X), which prior to analysis appear as indexed components.
26618 (Analyze_One_Call): Complete the error notification to help new Ada
26619 2005 users.
26620 (Analyze_Allocator): For an allocator without an initial value, where
26621 the designated type has a constrained partial view, a discriminant
26622 constraint is illegal.

26640 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
26641 both bound checks, rather than a conjunction.
26642 (Insert_Valid_Check): If the expression is an actual that is an indexed
26643 component of a bit-packed array, force expansion of the packed element
26644 reference, because it is specifically inhibited elsewhere.

26706 corresponding stream-oriented attribute has been defined by an
26707 attribute definition clause. When such a clause occurs, a TSS is set

26771
26772 * exp_strm.adb (Build_Mutable_Record_Read_Procedure): Reorganize to
26773 first read discriminants into temporary objects, performing checks on
26774 the read values, then possibly performing discriminant checks on the
26775 actual (if it is constrained), and only finally reading the components
26776 into a constrained temporary object.
26777 (Build_Elementary_Input_Call): Adjust the specific circuitry for the
26778 case of reading discriminants of a mutable record type to recognize
26779 the new form of the code generated by

26791 treated as available for a limited private type if there is an
26792 attribute_definition_clause that applies to its full view, but not in
26793 other cases where the attribute is available for the full view
26794 (specifically, the sole fact that the full view is non-limited does not
26795 make the attribute available for the partial view).
26796 (Build_Access_Subprogram_Type): Diagnose attempt to apply 'access to a
26797 non-overloaded intrinsic subprogram.
26798 (Check_Stream_Attribute): Reject an attribute reference for an

26802 (Stream_Attribute_Available): New function to determine whether a stream
26803 attribute is available at a place.

29087 (Resolve_Slice): If the prefix is an access to an unconstrained array,
29088 compute the actual subtype of the designated object to impose the proper
29089 index constraints.
29090 (Resolve_Selected_Component): Do not insert an access check if the
29091 prefix is an access type: such a node is expanded into an explicit
29092 dereference, on which the access check is performed anyway. Removes
29093 expensive duplicate checks.
29094 (Resolve_Call): Use new flag Is_Obsolescent and field
29095 Obsolescent_Warning so that pragma Obsolescent works on library
29096 subprograms.
29097 Add support for wide wide character type
29098 (Resolve_Allocator): Replace the error message on wrong null-exclusion
29099 value by a warning message.
29100 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
29101 as fixed-point, and one of the operands is non-static and universal, it
29102 can only be an illegal exponentiation operation, in which case there is
29103 no real value to retrieve.
29104
29105 * exp_strm.adb: Add support for wide wide character type

29138 (Eval_Arithmetic_Op): Check for compile time known signed integer
29139 overflow in the non-static case.
29140 (Subtypes_Statically_Match): A formal scalar type and its base type do
29141 not statically match.
29142
29143 * sem_util.adb (Collect_Primitive_Operations): Minor change of "/=" to
29144 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
29145 subtype).
29146 (Unit_Declaration_Node): Ditto.
29147 (Is_Variable_Prefix): For the case of an indexed component whose prefix
29148 has a packed array type, the prefix has been rewritten into a type

29152 * stand.ads: Add types Wide_Wide_Character and Wide_Wide_String
29153
29154 * stringt.ads, stringt.adb: Handle full UTF-32 range.
29155 Remove ["0A"] from comment, since it can look like a line terminator.
29156 Currently we don't permit this, but this is under discussion by the
29157 ARG, and it is easy enough to use a different example.
29158
29159 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
29160 handling UTF-32 encoding for wide wide character.

29169 notify that constraint error will be raised at run-time
29170 because a null value is assigned to a null-excluding object.
29171 Remove some obsolete declarations and make Char_Code
29172 unsigned.
29173
29174 * a-except.adb (Rcheck_30): New subprogram. Addition of the message

29182 Current algorithm for removing duplicate checks is over-eager in this
29183 case.
29184
29185 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
29186 null-exclusion value by a warning message

29199 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
29200 defined for subprogram renaming declarations. When set, the field
29201 indicates the defining entity of a corresponding formal subprogram
29202 when the renaming corresponds to a formal subprogram association in an
29203 instantiation.
29204 (Set_Corresponding_Formal_Spec): New procedure to return
29205 Corresponding_Formal_Spec field.
29206 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

29217
29218 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
29219 describing the new layout.
29220 (Dispatch_Table): The expander computes the actual array size, allocates
29221 the Dispatch_Table record accordingly, and generates code that displaces
29222 the base of the record after the Typeinfo_Ptr component. The access to
29223 these components is done by means of local functions.
29224 (Offset_To_Top): New function.
29225 (Typeinfo_Ptr): New function.
29226 (Get_TSD): Modified to access the new position of the TSD.

29237 N_Formal_Subtype_Declaration (which is now a subtype).
29238 (Analyze_Formal_Subprogram): Add handling for
29239 N_Formal_Abstract_Subprogram, marking the formal as abstract and
29240 dispatching, setting the controlling status of the formal parameters
29241 and result, and issuing an error if there is no controlling type for
29242 the formal subprogram.
29243 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
29244 which is an unclean use of that field, we set the new field
29245 Corresponding_Formal_Spec to make the formal subprogram available to
29246 processing in Analyze_Subprogram_Declaration.
29247 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
29248 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
29249 Constrained, so that it is is does not statically match its anonymous

29253 abstract formal subprograms in error check for functions returning
29254 abstract types. Set scope of new designator for
29255 a parameterless subprogram, so that it is available when checking the
29256 body for nested subprograms, before full analysis of said body.
29257 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
29258 subprogram only if inner one comes from source.
29259 (Analyze_Function_Call): If the call is given in object notation, the
29260 analysis of the name rewrites the node and analyzes it with the proper
29261 argument list. After analyzing the name, if the call has been rewritten
29262 and the result type is set, no further analysis is needed.
29263 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
29264 mark in function specification, in a context where the formals are
29265 visible and hide outer homographs.
29266
29267 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
29268 as the tagged type for the cases of abstract formal subprograms and
29269 renamings of those. Clean up spec comments.
29270 (Check_Dispatching_Context): Add error message to indicate "abstract
29271 procedure", covering the case of a call to a formal abstract procedure
29272 that has statically tagged operands.

30281 dereference is rewritten to an explicit one, generate a reference to
30282 the entity denoted by its prefix using the original prefix node, so

30284 access value, if appropriate.
30285

30290 subprogram body.

30296 intrinsic
30297
30298 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
30299 leaving call unchanged.
30300 This deals with the case where the pragma Import specified
30301 an external name, to be handled by the back end.
30302
30303 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of

30327 for generation of DSA code targeted to the PolyORB PCS.
30328 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
30329 implementation of the partition communication subsystem in ancillary

30363 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
30364 and the Has_Pragma_Unreferenced flag for each formal before analyzing

30398 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
30399 used to record an implicit dereference as a read operation on its
30400 prefix when operating under -gnatc. Necessary to avoid spurious
30401 'variable assigned but never read' warnings in that mode.
30402 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
30403 is a non-overloaded implicit dereference, call the above subprogram to
30404 ensure proper recording of references.

30510 parameter with the priority class of the parent process instead of
30511 always using the NORMAL_PRIORITY_CLASS.

305202004-11-18 Olivier Hainque <hainque@adacore.com>
30521
30522 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
30523 address of which may be used to represent "others" and "all others"
30524 choices in exception tables, instead of the current harcoded
30525 (void *)0 and (void *)1.
30526 (Setup_Exception): Do nothing in the GNAT SJLJ case.
30527
30528 * gigi.h (others_decl, all_others_decl): New decls representing the
30529 new Others_Value and All_Others_Value objects.
30530 (struct attrib): Rename "arg" component as "args", since GCC expects a
30531 list of arguments in there.
30532
30533 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
30534 corresponding objects exported by a-exexpr, instead of hardcoded dummy
30535 addresses.
30536
30537 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
30538 others_decl and all_others_decl instead of hardcoded dummy addresses
30539 to represent "others" and "all others" choices, which is cleaner and
30540 more flexible with respect to the possible eh pointer encoding policies.
30541
30542 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
30543 (process_attributes): Account for the naming change of the "args"
30544 attribute list entry component.
30545
30546 * decl.c (build_attr_list): Rename into prepend_attributes to allow
30547 cumulating attributes for different entities into a single list.
30548 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
30549 attributes for the current entity and propagate first subtype
30550 attributes to other subtypes.
30551 <E_Procedure>: Attribute arguments are attr->args and not
30552 attr->arg any more.
30553 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
30554 argument provided, as this is what GCC expects. Use NULL_TREE instead
30555 of 0 for trees.

30574 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
30575 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
30576 in use.
30577 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
30578 Add_RACW_Features.
30579 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
30580 Add_RAST_Features.
30581 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
30582 distribution subprogram identifiers that are either subprogram numbers
30583 or strings.

30585 string distribution identifiers assigned to a given subprogram.
30586 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
30587 (Add_RAS_Dereference_TSS): Add comments.
30588 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
30589 is not referenced yet because it will be used by the PolyORB DSA
30590 implementation.
30591 (Insert_Partition_Check): Remove fossile code.
30592 (First_RCI_Subprogram_Id): Document this constant.
30593 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
30594 RAS_Access TSS.
30595 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
30596 replaced with calls to Get_Library_Unit_Name_String. Previously there
30597 were several instances of the same code in different locations in the
30598 compiler; this checkin completes the replacement of all of these
30599 instances with calls to a common subprogram.
30600 Minor reformatting.
30601
30602 * sem_dist.adb: Remove comment noting that RPC receiver generation
30603 should be disabled for RACWs that implement RASs.
30604 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
30605
30606 * sem_util.ads, sem_util.adb (Has_Stream): New function
30607 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
30608 qualified name of a library unit into the name buffer.

30627
30628 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
30629 (Expand_Pragma_Psect_Object): New procedure
30630 These procedures contain the revised and cleaned up processing for
30631 these two pragmas. This processing was formerly in Sem_Prag, but
30632 is more appropriately moved here. The cleanup involves making sure
30633 that the pragmas are properly attached to the tree, and that no
30634 nodes are improperly shared.
30635
30636 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
30637 pragmas to Exp_Prag, which is more appropriate.
30638 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
30639 check for duplicates Remove use of Is_Psected flag, no longer needed.
30640 Use new Make_String_Literal function with string.
30641
30642 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30643 that are functions return universal values, that have to be converted
30644 to the context type.
30645 Use new Make_String_Literal function with string.
30646 (Get_Stream_Convert_Pragma): New function, replaces the use of
30647 Get_Rep_Pragma, which had to be kludged to work in this case.
30648
30649 * freeze.adb: Use new Has_Rep_Pragma function
30650
30651 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30652 function with string.
30653 Use new Has_Rep_Pragma function.
30654
30655 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
30656 string argument.

30660 * errout.ads, errout.adb: (First_Sloc): New function
30661
30662 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
30663 check (-gnatyx) instead of being included as a redundant construct
30664 warning.
30665
30666 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
30667 Style_Check_Order_Subprograms.
30668
30669 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
30670 stylesw.adb: Add Style_Check_Xtra_Parens
30671
30672 * usage.adb: Add line for -gnatyx (check extra parens)
30673

30677 Robert Dewar <dewar@adacore.com>
30678
30679 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30680 discriminant of a constrained subtype, analyze the copy of the
30681 corresponding constraint, because in some cases it may be only
30682 partially analyzed.
30683 Removes long-lived ??? comments.
30684
30685 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30686 handled controlled or secondary-stack expressions within the
30687 iteration_scheme of a loop.
30688
30689 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30690 bounds that may contain functions calls, to prevent memory leaks when
30691 the bound contains a call to a function that uses the secondary stack.
30692 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30693 generate temporaries for loop bounds that might contain function calls
30694 that require secondary stack and/or finalization actions.
30695
30696 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30697 selected component and the selector is overloadable (not just a
30698 function) treat as function call, Analyze_Call will disambiguate if
30699 necessary.
30700 (Analyze_Selected_Component): Do not generate an actual subtype for the
30701 selected component if expansion is disabled. The actual subtype is only
30702 needed for constraint checks.
30703 (Analyze_Allocator): If restriction No_Streams is set, then do
30704 not permit objects to be declared of a stream type, or of a
30705 composite type containing a stream.
30706
30707 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30708 No_Streams no longer prohibits with'ing this package.
30709
30710 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30711 discriminants, but the parent base has unknown discriminants, there is
30712 no discriminant constraint to inherit. Such a discrepancy can arise
30713 when the actual for a formal type with unknown discriminants is a
30714 similar private type whose full view has discriminants.
30715 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30716 do not permit objects to be declared of a stream type, or of a
30717 composite type containing a stream.
30718
307192004-11-18 Ed Schonberg <schonberg@adacore.com>
30720
30721 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30722 protected operations.
30723
30724 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30725 generated name, it complicates decoding in gdb and hinders debugging
30726 of protected operations.
30727 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30728 flag for the protected entry barrier function.
30729 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30730 flag for the protected entry function.
30731
307322004-11-18 Nicolas Setton <setton@adacore.com>
30733
30734 * expect.c: Define __unix__ when __APPLE__ is defined.

30736 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30737 Darwin-specific section.
30738
30739 * lang-specs.h: Change the placement of the %1 marker.
30740 Works around the fact that gcc adds -fPIC by default under Darwin.
30741
307422004-11-18 Ed Schonberg <schonberg@adacore.com>
30743
30744 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30745 type of the object with the packed array type, set the Analyzed flag
30746 on the object if it is an entity or simple indexed component, to avoid
30747 spurious type errors.

30753 separate line from the version message.
30754
307552004-11-18 Ed Falis <falis@adacore.com>
30756

30758 vthreads.
30759 (init_float): Eliminate initialization of floating point status for
30760 AE653. The instructions have no effect for vThreads.
30761
307622004-11-18 Vincent Celier <celier@adacore.com>

30770 for Detect_Blocking which is redundant with the check done within the
30771 procedure Protected_Single_Entry_Call.
30772 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30773 Detect_Blocking which is redundant with the check done within the
30774 procedure Protected_Single_Entry_Call.
30775
307762004-11-18 Vincent Celier <celier@adacore.com>
30777
30778 * makegpr.adb (Compile): Put the compiling switches (in package
30779 Compiler and on the command line) immediately after "-c", instead of
30780 at the end of the command line invocation of the compiler, when
30781 compiling a non-Ada file.
30782 (Build_Global_Archive): When there is no need to rebuild the archive,
30783 set Global_Archive_Exists, so that the archive is passed to the linker
30784 if one is needed.

30794 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30795 objects rather than forbidding dependencies on the package Ada.Streams.

30825 there is no use of GNAT.Sockets.Constants.
30826 Remove remaining pragma Import for C_Write
30827 Remove C_Read and C_Write from internal implementation unit
30828 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30829 the read and write functions from the system runtime library is fine
30830 on UNIX but won't work under Windows).
30831
30832 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30833 (Check_Selector): Use C_Recv instead of C_Read.
30834 Selectors are the GNAT.Sockets abstraction to perform a select()
30835 call on a set of descriptors. To allow abortion of an ongoing
30836 select operation, some data is written to a dedicated socket that
30837 is always monitored.
30838 Under Windows, the write and read library functions cannot operate
30839 on sockets, so we need to use send and recv instead, which is portable
30840 across all supported platforms.
30841
30842 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30843 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable

30892 sections were just mistakenly ignored. The former is
30893 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30894 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30895 of hpux. This prevents an unwanted definition of the symbol

30936 JM type only if its size matches that of the wrapper. When a size is
30937 prescribed and the field is not aliased, remove the wrapper of a JM
30938 type only if the size is not greater than that of the packed array.

30953 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30954 be expandable in place even if the aggregate does not come from source.
30955 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30956 designated object of an allocator in place, rather than building it
30957 first on the stack. The previous scheme forces a full copy of the array,
30958 and may be altogether unsusable if the size of the array is too large

30990 GARLIC and PolyORB versions of the distributed systems annex.
30991 (DSA_Implementation_Name): This enumeration lists the possible
30992 implementations of the Partition Communication Subsystem for the
30993 Distributed Systems Annex (DSA). The three available implementations
30994 are the dummy stub implementation (No_DSA), and two versions based on
30995 two different distribution runtime libraries: GARLIC and PolyORB. Both
30996 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution

31028 memory before the faulting page we properly test the process read
31029 access for this address using appropriate Win32 routine.
31030 (HPUX sections): guard with "__hpux__" instead of "hpux".
31031
310322004-10-26 Robert Dewar <dewar@gnat.com>
31033

31036 handle the case of multiple parameters.
31037

31042 the library directory only if there is no object directory or if the
31043 library directory contains ALI files.

31067 correctly.
31068 (Double_Divide): Handle overflow case of largest negative number
31069 divided by minus one.

31097 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
31098 current instance appears within a unit that is directly in the context
31099 of the main unit.
31100 Used to determine whether the body of the instance should be analyzed
31101 immediately after its spec, to make its subprogram bodies available
31102 for front-end inlining.
31103 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
31104 constraint is not allowed on the component type (AARM 12.5.3(3))
31105
311062004-10-26 Cyrille Comar <comar@act-europe.fr>
31107

31109 'Storage_Pool): enhance, document & limit detection of non-sharable
31110 internal pools.
31111
31112 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
31113
31114 * s-pooglo.ads: Add more documentation now that this pool is properly
31115 documented.
31116
311172004-10-26 Ed Schonberg <schonberg@gnat.com>
31118
31119 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
31120 or protected type with discriminants, do not constrain the
31121 corresponding record type if the subtype declaration has no
31122 discriminant constraints. This can be the case in source code, or in
31123 the subtype declaration created to rename an actual type within an
31124 instantiation.
31125
311262004-10-26 Ed Schonberg <schonberg@gnat.com>
31127
31128 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
31129 different kind of stub (possibly wrong name for file), do not check
31130 for conformance.
31131 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
31132 includes call to some function that returns an unconstrained type, do
31133 not inline.
31134
311352004-10-26 Ed Schonberg <schonberg@gnat.com>
31136
31137 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
31138 appear in the code for the main unit. Dependencies among units in the
31139 context of the main unit are established when those other units are
31140 compiled. Otherwise spurious elaboration constraints can generate
31141 incorrect elaboration circularities.

31144 Ed Schonberg <schonberg@gnat.com>
31145
31146 * sem_util.adb (Is_Aliased_View): Defend against the case where this
31147 subprogram is called with a parameter that is not an object name. This
31148 situation arises for some cases of illegal code, which is diagnosed
31149 later, and in this case it is wrong to call Is_Aliased, as that might
31150 cause a compiler crash.
31151 (Explain_Limited_Type): Refine previous fix to include
31152 inherited components of derived types, to provide complete information.
31153
31154 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
31155 is the prival for a protected object.
31156 It is necessary to mark this entity as a variable, in addition to
31157 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
31158 modified to avoid checking the Aliased flag on entities that are not
31159 objects. (Checking that flag for non-objects is erroneous and could
31160 lead to a compiler crash).
31161
311622004-10-26 Robert Dewar <dewar@gnat.com>
31163
31164 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
31165 X_Frac = 0.5, then we know that the number X must be positive.
31166 (Succ): Remove the same redundant test, and also fix the primary test
31167 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
31168 Minor reformatting
31169 (Decompose): Add fuller comments to spec
31170
311712004-10-26 Pascal Obry <obry@gnat.com>
31172
31173 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
31174 validity (process must have read access). Set to 0 in all other cases.
31175 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
31176 violation on Win32.
31177 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
31178 segmentation violation.

311802004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
31181
31182 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
31183 whose type is a constructed subtype of an aliased object with an
31184 unconstrained nominal subtype, convert the actual to the constructed
31185 subtype before taking its address.

31203 memory pools provided as part of the GNAT library.
31204 Remove "virtual" from declaration of A::method2 in
31205 the simple example of Ada/C++ mixed system.
31206 Library Projects may be virtually extended: their virtual extensions
31207 are not Library Projects.
31208 Added section on extending project hierarchies.

31780 non-controlling anonymous access formals.
31781

31783 subprogram.
31784 New implementation of expansion for remote access-to-subprogram types,
31785 based on the RACW infrastructure.
31786 This version of sem_dist is compatible with PolyORB/DSA as well as
31787 GLADE.
31788
31789 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31790 Asynchrronous that applies to a remote access-to-subprogram type, mark
31791 the underlying RACW type as asynchronous.

31803 * exp_ch3.adb (Expand_Derived_Record): Rename to
31804 Expand_Record_Extension.
31805 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31806 a component declaration must remain attached at that point in the
31807 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31808 It is therefore necessary to take a copy of the expression when building
31809 the corresponding assignment statement in the init proc.
31810 As a side effect, in the case of a derived record type, we now see the
31811 original expression, without any rewriting that could have occurred
31812 during expansion of the ancestor type's init proc, and we do not need
31813 to go back to Original_Node.

31822 New subprograms. Used to create a proxy tagged object for a remote
31823 subprogram. The proxy object is used as the designated object
31824 for RAS values on the same partition (unless All_Calls_Remote applies).
31825 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31826 System.Partition_Interface.Get_Unique_Remote_Pointer.

31833
31834 * exp_dist.ads (Copy_Specification): Update comment to note that this
31835 function can copy the specification from either a subprogram
31836 specification or an access-to-subprogram type definition.

31845 add a polling call if the subprogram is to be inlined by the back-end,

31848 * checks.adb (Apply_Alignment_Check): If the expression in the address
31849 clause is a call whose name is not a static entity (e.g. a dispatching

34081
34082 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
34083 includes case of a variable referenced on the left hand side of an
34084 assignment, therefore remove redundant code. Variables and prefixes of
34085 indexed or selected components are now marked as referenced on left
34086 hand side. Warnings are now properly emitted when variables or prefixes
34087 are assigned but not read.
34088
34089 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
34090 left hand side referenced variables. Private access types do not
34091 produce the warning "variable ... is assigned but never read".
34092 Add also additional checks to left hand side referenced variables.
34093 Aliased, renamed objects and access types do not produce the warning
34094 "variable ... is assigned but never read" since other entities may read
34095 the memory location.

34182
34183 * sem_ch12.adb (Same_Instantiated_Constant): New name for
34184 Same_Instantiated_Entity.
34185 (Same_Instantiated_Variable): Subsidiary to
34186 Check_Formal_Package_Instance, to recognize actuals for in-out generic
34187 formals that are obtained from a previous formal package.
34188 (Instantiate_Subprogram_Body): Emit proper error when
34189 generating code and the proper body of a stub is missing.
34190
34191 * sem_ch4.adb (Remove_Address_Interpretations): If the operation still
34192 has a universal interpretation, do the disambiguation here.
34193
34194 * exp_ch4.adb (Expand_N_Type_Conversion,
34195 Expand_N_Unchecked_Type_Conversion): Special handling when target type
34196 is Address, to avoid typing anomalies when Address is a visible integer
34197 type.
34198
34199 * exp_ch6.adb (Expand_N_Subprogram_Body): Use Is_Descendent_Of_Address
34200 to determine whether a subprogram should not be marked Pure, even when
34201 declared in a pure package.
34202
342032004-05-27 Jose Ruiz <ruiz@act-europe.fr>
34204
34205 * gnat_ugn.texi: Replace pragma Ravenscar by pragma Profile.
34206
34207 * gnat_rm.texi: Replace Max_Entry_Queue_Depth by Max_Entry_Queue_Length
34208 Document No_Dynamic_Attachment, that supersedes No_Dynamic_Interrupts.
34209 Update the documentation about the Ravenscar profile, following the
34210 definition found in AI-249.
34211
34212 * sem_prag.adb: Use FIFO_Within_Priorities and Ceiling_Locking when
34213 setting the Profile (Ravenscar). This must be done in addition to
34214 setting the required restrictions.
34215
34216 * rtsfind.ads: Add the set of operations defined in package
34217 Ada.Interrupts.

34230 a significant reference. Warnings are now properly emitted when a
34231 discriminated type is not referenced.
34232
34233 * lib-xref.adb (Generate_Reference): A deferred constant completion,
34234 record representation clause or record type discriminant does not
34235 produce a reference to its corresponding entity. Warnings are now
34236 properly emitted when deferred constants and record types are not
34237 referenced.

34261
34262 * a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi
34263 with 192 bits of precision, sufficient to reduce a double-extended
34264 arguments X with a maximum relative error of T'Machine_Epsilon, for X
34265 in -2.0**32 .. 2.0**32.
34266 (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
34267 reduction by the processor, which only uses a 68-bit approximation of
34268 Pi.
34269 (Tan): Always reduce arguments and compute function either using
34270 the processor's fptan instruction, or by dividing sin and cos as needed.

34312 limited view by a package entity that references the first shadow
34313 entity plus the first shadow private entity (required for limited-

34567
34568 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
34569 during the evaluation of the expression that initializes the object,

34572
34573 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library

36430 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
36431 attribute reference does not denote a subtype, it can be any
36432 expression that has a classwide type, potentially after an implicit
36433 dereference. In particular, the prefix can be a view conversion for
36434 a classwide type (for which Is_Object_Reference holds), but it can
36435 also be a value conversion for an access-to-classwide type. In the
36436 latter case, there is an implicit dereference, and the original node
36437 for the prefix does not verify Is_Object_Reference.

36456 the renamed entity.

36737 get_action_description_for, and expanded to take care of the VMS
36738 specifities.
36739 (get_action_description_for): Use is_handled_by instead of an explicit
36740 complex condition to decide if the current choice at hand catches the
36741 propagated occurrence.

36754 routine which will now be able to call the appropriate exception data
36755 accessor instead.
36756
36757 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36758 component of Standard_Exception_Type to be the closest possible to
36759 Exception_Code in System.Standard_Library, that we cannot get at this
36760 point. Expand a ??? comment to notify that this type node should
36761 probably be rewritten later on.
36762
36763 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36764 registration call to include a pointer to the exception object in the
36765 arguments.

36788 following -o, in canonical case, does not end with the executable
36789 suffix. When in verbose mode and executable file name does not end
36790 with executable suffix, output the executable name, in canonical case.

36810 tagged type is inherited, and the parent operation is not frozen yet,
36811 force generation of a freeze node for the inherited operation, so the
36812 corresponding dispatch entry is properly initialized.

36820 bit-aligned field and the right-hand side a string literal, introduce
36821 a temporary before expanding assignment into a loop.
36822
36823 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36824 priority in full, to ensure that any expanded subepxressions of it are
36825 elaborated in the scope of the init_proc.
36826
36827 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36828 after object declaration, skipping over code that may have been
36829 generated for validity checks.
36830
36831 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36832 discriminants, ignore the known discriminants of its full view, if
36833 any, to check legality.
36834
36835 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36836 component if type has unknown discriminants.

36870 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36871 Insert_Dereference_Action when rewriting an implicit dereference into
36872 an explicit one, this will be taken care of during expansion of the
36873 explicit dereference.
36874 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36875 of non-packed slices, since the dereference action generated by
36876 expansion of the explicit dereference is needed in any case.
36877 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36878 analyze and resolve the rewritten explicit dereference so it is seen
36879 by the expander.
36880 (Insert_Dereference_Action): This procedure is now called only for the
36881 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36882 dereferences that do not come from source (including explicit
36883 dereferences resulting from rewriting implicit ones), but do not
36884 recursively insert a check for the dereference nodes contained within
36885 the check.
36886 (Insert_Dereference_Action): Clarify and correct comment.

37755 region.
37756
37757 * utils.c (create_field_decl): Augment the head comment about bitfield
37758 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
37759 here, because the former is not accurate enough at this point.
37760 Let finish_record_type decide instead.
37761 Don't make a bitfield if the field is to be addressable.
37762 Always set a size for the field if the record is packed, to ensure the
37763 checks for bitfield creation are triggered.
37764 (finish_record_type): During last pass over the fields, clear
37765 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
37766 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
37767 from DECL_BIT_FIELD.

42412 referring concrete lexical entities (keywords, attribute names
42413 etc.), and @syntax for ARM grammar elements. Use @r for English

44205 * types.ads (Get_Hex_String): Returns the hexadecimal representation
44206 for a word. This is currently used only for CRC. In previous version,
44207 the checksum was using a representation with all letter being
44208 upper-case. With the new implementation (using CRC) we do not remove
44209 the 32th bit of the CRC, so we can have an upper-case starting letter
44210 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
44211 It is ambigous since the CRC was optional and could be followed by
44212 options like EB, EE. So now this routines uses lower-case letter for
44213 the hexadecimal representation. Strange enough only lower case letters
cfac6e9f 44214 where checked in Scan_ALI (even if this was not a possible case).
