1999 result type is class-wide and inherently limited, and the expression
2000 has a specific type, create a return object of the specific type, for

2003 component assignments).
2004
2005 * sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error
2006 about a type mismatch for a class-wide function with a return object
2007 having a specific type when the object declaration doesn't come from

2061 check when the type
2062 of the extended return is an anonymous access_to_subprogram type.

2065 (Resolve_Call): Insert a dereference if the type of the subprogram is an
2066 access_to_subprogram and the context requires its return type, and a

2330 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2331 Orig_Prev to Prev in the case where the actual is N_Function_Call or

2334 accessibility level, and based on testing this code is apparently no
2335 longer needed at all.

4470 (P_Access_Definition): Change the error message when parsing "access

4493 (Validate_Remote_Access_Object_Type_Declaration):
4494 New local subprogram Is_Valid_Remote_Object_Type, replaces
4495 Is_Recursively_Limited_Private.
4496 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4497 non-controlling formals (and the return type, even though this is not
4498 explicit in the standard) must support external streaming.
4499 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4500 as above for of RAS types and RCI subprograms. (The return type is not
4501 checked yet).
4502 Update comments related to RACWs designating limited interfaces per
4503 ARG ruling on AI05-060.
4504
4505 * sem_util.ads, sem_util.adb
4506 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4507 Is_Remote_Call_Interface to identify RACW types in a stable and
4508 consistent way. We used to rely in this predicate on the privateness of
4509 the designated type and its ancestors, but depending on the currently
4510 visible private parts, this caused false negatives. We now uniformly
4511 rely on checks made at the point where the RACW type is declared.

4520 restricting use of predefined assignment with tagged types that have
4521 convention CPP.
4522 (Analyze_Object_Declaration): Relax the check regarding deferred
4523 constants declared in scopes other than packages since they can be
4524 completed with pragma Import.
4525 Add missing escaping of all-caps word 'CPP' in error messages.
4526 (Build_Discriminated_Subtype): Do not inherit representation clauses
4527 from parent type if subtype already carries them, because they are
4528 inherited earlier during derivation and already include those that may
4529 come from a partial view.
4530
4531 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):

4544 mark.
4545 (Analyze_Call): Insert dereference when the prefix is a parameterless
4546 function that returns an access to subprogram and the call has
4547 parameters.
4548 Reject a non-overloaded call whose name resolves to denote
4549 a primitive operation of the stub type generated to support a remote

4568 through dispatching, never through static calls).
4569 (Collect_Interps): When only one interpretation has been found, set N's
4570 Entity and Etype to that interpretation, otherwise Entity and Etype may
4571 still refer to an interpretation that was ignored by Add_One_Interp,
4572 in which case would end up with being marked as not overloaded but with

8289 (Analyze_Pragma, case Complex_Representation): Improve error message.
8290 (Analyze_Pragma, case Assert): When assertions are disabled build the

8452 limited ancestor part, initialize controllers of enclosing record
8453 before expanding ancestor aggregate.

8455 code to call Initialize if the component is controlled, and explicit
8456 assignment of null if the component is an access type.
8457
8458 Handle properly aggregates for limited types that appear in object
8459 declarations when the aggregate contains controlled values such as

8481 declarations.
8482 (Predefined_Primitive_Bodies): Add body of "=" if the parent of the

8587 mismatches in gigi.
8588 (Resolve_Actuals): If the actual is an entity name, generate a
8589 reference before the actual is resolved and expanded, to prevent
8590 spurious warnings on formals of enclosing protected operations.
8591 (Analyze_Overloaded_Selected_Component): If type of prefix if
8592 class-wide, use visible components of base type.
8593 (Resolve_Selected_Component): Ditto.
8594 (Resolve_Short_Circuit): Detect case of pragma Assert argument
8595 evaluating to False, and issue warning message.

8615
8616 * layout.adb (Resolve_Attribute, case 'Access): If designated type of
8617 context is a limited view, use non-limited view when available. If the
8618 non-limited view is an unconstrained array, this enforces consistency
8619 requirements in 3.10.2 (27).
8620 (Layout_Type): For an access type whose designated type is a limited
8621 view, examine its declaration to determine if it is an unconstrained
8622 array, and size the access type accordingly.
8623 (Layout_Type): Do not force 32-bits for convention c subprogram
8624 pointers in -gnatdm mode, only if real vms target.
8625

8632 view is an unconstrained array, this enforces consistency requirements
8633 in 3.10.2 (27).
8634 (Layout_Type): For an access type whose designated type is a limited
8635 view, examine its declaration to determine if it is an unconstrained
8636 array, and size the access type accordingly.

8690 Do not give warning on exception raise in No_Return function
8691
8692 * sem_ch13.adb (Analyze_Record_Representation_Clause): If an inherited
8693 component has two inconsistent component clauses in the same record
8694 representation clause, favor the message that complains about
8695 duplication rather than inconsistency.
8696 Update comments.
8697 (Record_Representation_Clause): Do not warn on missing component
8698 clauses for inherited components of a type extension.
8699 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
8700 an overloadable item if it is a pragma that can apply to multiple
8701 overloadable entities (e.g. Inline) because a pragma cannot be on
8702 more than one chain at a time.
8703 (Validate_Unchecked_Conversion): Add code to warn on unchecked
8704 conversion where one of the operands is Ada.Calendar.Time.
8705 (Analyze_Attribute_Definition_Clause): Fix typo in error message.

8719 file name.
8720 (Body_Suffix_Id_Of, Spec_Suffix_Id_Of): new version that takes a name_id
8721 as a parameter. This parameter is in fact always "ada" in all calls, and
8722 we were doing 160560 extra calls to Name_Find to convert it to Name_Ada
8723 while loading a project with 40000 files
8724
8725 * prj-attr.adb: Fix name of attribute Dependency_Driver

8767 (Look_For_Sources): Put the unit exceptions in hash table
8768 Unit_Exceptions
8769 (Get_Unit_Exceptions): Give initial value No_Source to local variable

8771 checking.
8772 (Get_Sources_From_File): Check that there is no directory information
8773 in the file names.
8774 (Look_For_Sources): Check that there is no directory information in the
8775 list of file names in Source_Files.

8792 (Opt.Follow_Links_For_Dirs): New flag
8793 (Project_Path_Name_Of): Cache information returned by this routine as

8831 * sem_ch10.adb (Check_Private_Child_Unit): A non-private library level
8832 subprogram body that acts as its own spec may not have a non-private
8833 WITH clause on a private sibling.
8834 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8835 child unit is a renaming, create an implicit with_clause on that
8836 parent, and not on the unit it renames, to prevent visibility errors
8837 in the current unit.
8838
88392007-12-13 Ed Schonberg <schonberg@adacore.com>
8840
8841 * sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram
8842 renaming declaration, use the Slocs of the formal parameters from the

8844 entities in the renaming declaration.
8845 (Analyze_Formal_Type_Declaration): Change the placement of the error
8846 message concerning illegal known discriminants. It is now posted on the

8853 generated for formal packages.
8854 (Validate_Derived_Type_Instance): Add a check that when a formal

8872
8873 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid
8874 generation of spurious error if parent is an interface type; caused
8875 because predefined primitive bodies will be generated later by
8876 Freeze_Record_Type.
8877 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
8878 flag.
8879 (Derive_Subprograms): Handle derivations of predefined primitives

8883 of Related_Interface to Related_Type.
8884 (Record_Type_Declaration): Minor reordering of calls to decorate the

8900 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
8901 formal of a generic subprogram. find candidate interpretations by
8902 scanning the list of generic formal declarations.:

8904 type from a limited_with_clause, and the full view is available, use it
8905 for subsequent semantic checks.
8906 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
8907 (Find_Primitive_Operation): New function.
8908 (Analyze_Overloaded_Selected_Component): insert explicit dereference

8926 (Analyze_Renamed_Primitive_Operation): new procedure to determine the
8927 operation denoted by a selected component.
8928 (Analyze_Renamed_Entry): Resolve the prefix of the entry name, because
8929 it can be an expression, possibly overloaded, that returns a task or
8930 an access to one.

8933 Gary Dismukes <dismukes@adacore.com>
8934
8935 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8936 requeue statement is dispatching. Do not emit an error when the name is
8937 not an entry and the context is a dispatching select. Add code to
8938 perform subtype conformance between the formals of the current entry
8939 and those of the target interface primitive.
8940 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8941 Timed_Entry_Call): Analyze the triggering statement as the first step of
8942 the processing. If this is a dispatching select, postpone the analysis
8943 of all select statements until the Expander transforms the select. This
8944 approach avoids generating duplicate identifiers after the Expander has
8945 replicated some of the select statements. In case the Expander is
8946 disabled, perform regular analysis.
8947 (Check_Triggering_Statement): New routine.
8948 (Analyze_Requeue): Exclude any interpretations that are not entries when
8949 checking overloaded names in a requeue. Also test type conformance for
8950 matching interpretations rather than requiring subtype conformance at
8951 that point to conform with the RM's resolution rule for requeues.
8952
89532007-12-13 Ed Schonberg <schonberg@adacore.com>
8954
8955 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8956 inherited operation is a defaulted tag-indeterminate call, and there is
8957 a statically tagged actual, use the static tag as a controlling actual
8958 for the defaulted actual.
8959
89602007-12-13 Geert Bosch <bosch@adacore.com>
8961
8962 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8978 (Collect_Abstract_Interfaces): Update occurrences of Related_Interface
8979 to Related_Type.
8980 (Collect_Interfaces_Info): Minor update to handle the two secondary
8981 dispatch tables. Update occurrence of Related_Interface to Related_Type.
8982 (Generate_Parent_Ref): Add parameter to specify entity to check

8984 initialize a component of a type with preelaborable initialization.
8985 This includes the case of a discriminal used in such a context.
8986 (Is_Dependent_Component_Of_Mutable_Object): Take into account the
8987 latest Ada 2005 rules about renaming and 'Access of
8988 discriminant-dependent components.

8990 subprograms (e.g. case of a package body).
8991 (Find_Parameter_Type): Factor routine from several other compiler files.
8992 Remove routine from Find_Overridden_Synchronized_Primitive.

9564

9661 that case of Ctyp to the array component type, which prevented proper

9663 condition that tests for array subtypes into just a test of

9919 to statically allocate the TSD.
9920
9921 * a-tags.ads:
9922 Minor reordering of the declarations in the private part. Required to
9923 add a level of indirection to the contents of the TSD component HT_Link.
9924 This is required to statically allocate the TSD.
9925
9926 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9927 Is_Statically_Allocated set from constant objects.
9928 Do not make exported constants created by the compiler volatile.
9929 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9930 as read-only.
9931
9932 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9933 before returning them.
9934
9935 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9936 public part of the package.
9937 (Make_DT): Move HT_Link component out of the TSD record. For this
9938 purpose Make_DT now declares a separate object that stores the
9939 HT_Link value, and initializes the TSD component with the address
9940 of this new object. The addition of this level of indirection is
9941 required to statically allocate the TSD because the TSD cannot
9942 have variable components.
9943 (Expand_Interface_Conversion): Improve the expanded code.
9944 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9945
9946 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9947 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9948 if we are building static dispatch tables then we must not generate
9949 extra code to register the primitive because the dispatch table will
9950 be built at the end of the library package; otherwise we notify that
9951 we cannot build the static dispatch table.

9970 for thunks associated with interface types.
9971
9972 * einfo.ads: Improve documentatation of Is_Internal
9973 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9974 associated with interface types.
9975 Extensive comment fixes regarding flags that appear in all entities. The
9976 documentation is now consistent for all such flags (there were a number
9977 of errors in the documentation in this regard).
9978
9979 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.

9981 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9982 of these procedures are passed a function call that already has
9983 build-in-place actuals (testing new flag
9984 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9985 the case where processing continues.
9986 (Expand_Call): If the call is generated from a thunk body then we
9987 propagate the extra actuals associated with the accessibility
9988 level of the access type actuals.
9989
9990 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9991 of each extra formal of a protected operation to reference the
9992 corresponding extra formal of the subprogram denoted by the
9993 operation's Protected_Body_Subprogram.
9994

10014 Analyze_Package_Specification.
10015
10016 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10017 preelaborable initialization of a full view in entity loop.
10018 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10019 its child units are use-visible only if they are visible child units.
10020
10021 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10022 whether an expression can be used within a type declaration that
10023 requires preelaborable init.
10024 (Check_Components): Replace inline code that does partial checking for
10025 preelaborable default expressions with call to
10026 Is_Preelaborable_Expression.
10027 (Has_Preelaborable_Initialization): In the case of a generic actual
10028 subtype, (that is, Is_Generic_Actual is True), return the result of
10029 applying Has_Preelaborable_Initialization to the generic actual's base
10030 type.

100322007-09-26 Hristian Kirtchev <kirtchev@adacore.com>

10036 (Is_Leap): Move the routine to the scope of Week_In_Year.
10037 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10038 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10039 avoids calling Time_Of and Split, thus making it more efficent.
10040 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10041
10042 * g-calend.ads (Week_In_Year): Change comment to reflect new
10043 implementation.
10044
100452007-09-26 Emmanuel Briot <briot@adacore.com>
10046
10047 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10048 Command_Line): New types
10049 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10050 support for defining how switches can be grouped on a command line (as
10051 is the case for -gnatw... for GNAT), and how simple switches can be
10052 used as aliases for more complex switches (-gnatwa is same as
10053 -gnatwbcef...)
10054 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10055 (Start, Current_*): New subprograms
10056 Added support for parsing an array of strings in addition to the real
10057 command line.
10058 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10059 be moved from the body to the private part of the spec.
10060 (*): All subprograms now have an extra parameter with default value to
10061 specify which parser should be used. For backward compatibility, it
10062 defaults to parsing the command line of the application. They were also
10063 modified to properly handle cases where each of the argument does not
10064 start at index 1 (which is always true for Ada.Command_Line, but not
10065 when processing any Argument_List).
10066 (Free): New subprogram
10067 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10068 Argument): New subprograms
10069 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10070 special characters like ':', '=',... are now handled in a single place,
10071 which makes the code more extensible eventually.
10072 (Getopt, Full_Switch): When the switch was returned as part of the
10073 special character '*', make sure it is prepended by the switch character
10074 ('-' in general), so that the application knows whether "foo" or "-foo"
10075 was specified on the command line.
10076
100772007-09-26 Florian Villoing <villoing@adacore.com>
10078
10079 * g-dirope.adb (Remove_Dir): In case we are removing directories
10080 recursively, make sure that if an exception is raised during the
10081 processing, the current working directory is reset to its initial
10082 value before propagating the exception.
10083

10087 a main program to bind, the first ALI is expected to contain the main
10088 subprogram and the names of the binder generated files will be derived
10089 from the first ALI file name.
10090 (Gnatbind): Fix insertion character in invocation of Error_Msg
10091
100922007-09-26 Vincent Celier <celier@adacore.com>

10136 being extended, instead of a shallow copy.
10137 (Process_Project_Tree_Phase_1): New procedure
10138 (Process_Project_Tree_Phase_1): New procedure

10168 ancestor of the derived type, the operations are inherited from the
10169 primary dispatch table of the parent.
10170 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls

10470 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10471 create an abstract subprogram in the case of 'Input. For 'Output we now
10472 create a real spec/body when the type is abstract, since it can
10473 potentially be called.
10474 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10475 body for 'Output when the type is abstract (only the creation of the
10476 body for 'Input is excluded when the type is abstract).
10477 (Stream_Operation_OK): Add an additional condition in the return
10478 statement, so that False will be returned for TTS_Stream_Input if the
10479 associated tagged type is an abstract extension. Add comments for
10480 return statement.
10481 (Expand_N_Object_Declaration): For the case of a shared passive
10482 variable, insert init proc call only after the shared variable
10483 procedures have been processed, because the IP call needs to undergo
10484 shared passive variable reference expansion, which requires these
10485 procedures to be available (and elaborated).

10501 to remove other spurious ambiguities on arithmetic operations involving

10503 type, when the operator is called in functional notation.
10504 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10505 is legal when the types match, even if the operation is currently
10506 hidden.

106832007-08-31 Bob Duff <duff@adacore.com>
10684
10685 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10686 concatenations of string literals into a single literal, in order to
10687 avoid very deep recursion in the front end, which was causing stack
10688 overflow.
10689
10690 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10691 string, and the right operand is a string literal (the case of "" &
10692 "..."), optimize by avoiding copying the right operand -- just use the
10693 value of the right operand directly.
10694
10695 * stringt.adb (Store_String_Chars): Optimize by growing the
10696 String_Chars table all at once, rather than appending characters one by
10697 one.
10698 (Write_String_Table_Entry): If the string to be printed is very long,
10699 just print the first few characters, followed by the length. Otherwise,
10700 doing "pn(n)" in the debugger can take an extremely long time.
10701
10702 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10703 Store_String_Char with Store_String_Chars.
10704

10715
10716 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10717 clauses of subunits, ignore limited_with_clauses that are illegal and
10718 have not been fully analyzed.
10719
107202007-08-31 Ed Schonberg <schonberg@adacore.com>
10721
10722 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10723 flag, for effiency. It is called when analyzing arithmetic operators
10724 and also for actuals in calls that are universal_integers. The flag is
10725 set for the predefined type address, and for any type or subtype
10726 derived from it.
10727
10728 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10729 Universal_Integer, when the formal is a descendent of address and the
10730 call appears in user code.
10731 (Analyze_Selected_Component): if the prefix is a private extension, the
10732 tag component is visible.
10733
10734 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
10735 entity flag.
10736
107372007-08-31 Robert Dewar <dewar@adacore.com>
10738
10739 * s-fileio.adb (Open): Normalize file name to lower case in non-case
10740 sensitive file name systems to avoid unexpected mismatch in Vista.

10771
10772 * vms_data.ads: Add new qualifier /STMT_NAME_ON_NEW_LINE for the new
10773 gnatpp '--separate-stmt-name' option.
10774 Add new qualifier /USE_ON_NEW_LIN for the new gnatpp '--use-on-new-line'
10775 option.
10776
10777 * gnat_ugn.texi: Add description for the new gnatpp
10778 '--separate-stmt-name' and '--use-on-new-line' options.

107952007-08-16 Gary Dismukes <dismukes@adacore.com>
10796
10797 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10798 associated with Standard_Debug_Renaming_Type, to be used as the type of
10799 the special variables whose names provide debugger encodings for
10800 renaming declarations.
10801
10802 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10803 (Set_Debug_Renaming_Link): Change to set Node25.
10804 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10805 (Write_Field25_Name): Add case for E_Variable to output
10806 "Debug_Renaming_Link".
10807 (Write_Field23_Name): Correct the output string for "Limited_View".
10808
10809 * exp_dbug.adb: Add with and use of Tbuild.
10810 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10811 and literal with creation of a variable of type
10812 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10813 and the entity of the renaming declaration.
10814 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10815 part of the name of a variable that has a Debug_Renaming_Link.
10816

10822 Ed Schonberg <schonberg@adacore.com>
10823 Javier Miranda <miranda@adacore.com>
10824
10825 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10826 ancestor part given by an aggregate to test for an unchecked conversion,
10827 since this can occur in some cases when the ancestor part is a function
10828 call, and we don't want to fall into the recursive call to this
10829 procedure in that case.
10830
10831 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10832 stream attributes on limited types to account for user-specified
10833 attributes as well as whether Input (resp. Output) becomes available
10834 due to Read (resp. Write) being available for the type. Change Boolean
10835 variable to the more accurate name
10836 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10837 double-"not" predicate at beginning of return statement to more
10838 understandable form.
10839
10840 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10841 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10842 in a block statement and use that as the first statement of the
10843 expanded return rather than incorrectly using the handled sequence as
10844 the first statement.
10845
10846 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10847 operation, generate an explicit freeze node for it rather than
10848 generating extra formals, to ensure that gigi has the proper order of
10849 elaboration for anonymous subtypes in the signature of the subprograms.
10850 (Build_In_Place_Formal): Move assertion to beginning of loop.
10851 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10852 applied to a function call (occurs for some cases of 'Input).
10853 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10854 applied to a function call (occurs for some cases of 'Input).
10855
10856 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10857 2005, generate an extended return statement enclosing the result object
10858 and 'Read call.
10859
10860 * freeze.adb (Freeze_Record_Type): Extend the current management of
10861 components that are access type with an allocator as default value: add
10862 missing support to the use of qualified expressions of the
10863 allocator (which also cause freezing of the designated type!)
10864 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10865 dispatching operation, since extra formals may be needed by calls to
10866 build-in-place functions (such as stream 'Input).
10867
10868 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10869 formals for 'Constrained and accessibility level in the case of a
10870 predefined dispatching operation.
10871
10872 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10873 point, no need to find the parent node.
10874
108752007-08-16 Javier Miranda <miranda@adacore.com>
10876
10877 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10878 and entry barriers.
10879
108802007-08-16 Javier Miranda <miranda@adacore.com>
10881
10882 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10883 is not really required and can introduce regression with the debugger.
10884 The original problem is fixed with the patch written for checks.adb.
10885
108862007-08-16 Thomas Quinot <quinot@adacore.com>

10893 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10894 Including_Non_Switch set to False.
10895 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10896 Including_Non_Switch set to False.
10897
10898 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10899 parameter Including_Non_Switch, defaulted to True. When
10900 Including_Non_Switch is False, options that are not switches and
10901 appear as relative path are not converted to absolute paths.
10902
109032007-08-16 Nicolas Roche <roche@adacore.com>
10904

10911
10912 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10913 currently inspected is a selected component, retrieve the entity of
10914 its selector.
10915 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10916 from the immediate ancestor of Main_Unit_Entity.
10917 (Install_Limited_Withed_Unit): Do not install the limited view of
10918 package P if P is reachable through an ancestor chain from package C
10919 and C also has a with clause for P in its body.
10920 (Has_Limited_With_Clause): New routine.

10933 initialize a limited object.
10934 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
10935 13/2 and 14/2.
10936 Make sure Has_Complex_Representation is inherited by derived type.

10951 Nicolas Setton <setton@adacore.com>
10952
10953 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10954 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10955 the statement which is being resolved comes from a predefined library
10956 unit, all non-predefined library interpretations are skipped.
10957 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10958 but the "&" is user defined, give an error, because the folding would
10959 be wrong.
10960
10961 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10962 the parser has folded a long sequence of concatenations of string

10966 and "JMP_BUF" variables as artificial.
10967 (N_String_Literal): Do not use alloca for very long string literals. Use
10968 xmalloc/free instead. Otherwise the stack might overflow.

11015 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
11016 Suppress unmodified in-out parameter warning in some cases
11017 This patch is a also fairly significant change to the way suppressible
11018 checks are handled.
11019
11020 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
11021 needed for access to concurrent record types generated by the expander.
11022 (Generate_Range_Check): When generating a temporary to capture the
11023 value of a conversion that requires a range check, set the type of the
11024 temporary before rewriting the node, so that the type is always
11025 properly placed for back-end use.
11026 (Apply_Float_Conversion_Check): Handle case where the conversion is
11027 truncating.
11028 (Get_Discriminal): Code reformatting. Climb the scope stack looking
11029 for a protected type in order to examine its discriminants.

11042 that has a specified Associated_Final_Chain, do not go up to the
11043 enclosing scope.
11044 (Expand_N_Type_Conversion): Test for the case of renamings of access
11045 parameters when deciding whether to apply a run-time accessibility
11046 check.
11047 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11048 aggregate code before allocator, and ahead of declaration for
11049 temporary, to prevent access before elaboration when the allocator is
11050 an actual for an access parameter.
11051 (Expand_N_Type_Conversion): On an access type conversion involving an
11052 access parameter, do not apply an accessibility check when the
11053 operand's original node was an attribute other than 'Access. We now
11054 create access conversions for the expansion of 'Unchecked_Access and
11055 'Unrestricted_Access in certain cases and clearly accessibility should
11056 not be checked for those.
11057
11058 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11059 includes a type conversion of a packed component that has been expanded,
11060 recover the original expression for the object, and use this expression
11061 in the post-call assignment statement, so that the assignment is made
11062 to the object and not to a back-end temporary.
11063 (Freeze_Subprogram): In case of primitives of tagged types not defined
11064 at the library level force generation of code to register the primitive
11065 in the dispatch table. In addition some code reorganization has been
11066 done to leave the implementation clear.
11067 (Expand_Call): When expanding an inherited implicit conversion,
11068 preserve the type of the inherited function after the intrinsic
11069 operation has been expanded.
11070
11071 * exp_ch2.ads, exp_ch2.adb
11072 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11073 of an entry formal appearing in an assignment statement does not assign
11074 to the formal.
11075 (Expand_Current_Value): Instead of calling a routine to determine
11076 whether the prefix of an attribute reference should be optimized or
11077 not, prevent the optimization of such prefixes all together.
11078
11079 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11080 component whose prefix is known to be of an access type is an implicit
11081 dereference and does not assign to the prefix.

11088 new itype.
11089 Add comments and correct harmless error in Build_NCT_Hash_Tables
11090 (Array_Aggr_Subtype): Associate each itype created for an index type to
11091 the corresponding range construct, and not to the aggregate itself. to
11092 maintain a one-to-one correspondence between itype and its associated
11093 node, to prevent errors when complex expression is copied.
11094 Fix mishandling of multiple levels of parens
11095
11096 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11097 treatment of limited views uniform for all visible declarations in a
11098 limited_withed package.
11099 (New_Copy_Tree): If hash table is being used and itype is visited,
11100 make an entry into table to link associated node and new itype.
11101 (Resolve_Record_Aggregate): Do not add an others box association for a
11102 discriminated record component that has only discriminants, when there
11103 is a box association for the component itself.
11104
11105 * par-ch4.adb: Fix mishandling of multiple levels of parens

11153 generation of a freezing node to ensure proper management of null
11154 excluding access types in the backend.
11155 (Create_Extra_Formals): Test base type of the formal when checking for
11156 the need to add an extra accessibility-level formal. Pass the entity E
11157 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11158 originally being done in a couple of cases), to ensure that the
11159 Extra_Formals list gets set on the entity E when the first entity is
11160 added.
11161 (Conforming_Types): Add missing calls to Base_Type to the code that
11162 handles anonymous access types. This is required to handle the
11163 general case because Process_Formals builds internal subtype entities
11164 to handle null-excluding access types.

11166 functions that need it, even when not marked Requires_Overriding.

11172 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11173 the implicit conversion of the expression done for anonymous access
11174 types. This is required to generate the code of the null excluding
11175 check (if required).
11176
11177 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11178 A formal parameter is never publicly referenceable outside of its body.
11179 (Check_References): For an unreferenced formal parameter in an accept
11180 statement, use the same warning circuitry as for subprogram formal
11181 parameters.

11183 Output_Unreferenced_Messages, containing the part of that routine that
11184 is now reused for entry formals as described above.

11196
11197 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11198 (Expand_N_Attribute_Reference): Further unify the handling of the
11199 three forms of access attributes, using common code now for all three
11200 cases. Add a test for the case of applying an access attribute to
11201 an explicit dereference when the context is an access-to-interface
11202 type. In that case we need to apply the conversion to the prefix
11203 of the explicit dereference rather than the prefix of the attribute.
11204 (Attribute_Version, UET_Address): Set entity as internal to ensure
11205 proper dg output of implicit importation.
11206 (Expand_Access_To_Type): Removed.
11207 (Expand_N_Attribute_Reference): Merge the code from the three cases
11208 of access attributes, since the processing is largely identical for
11209 these cases. The substantive fix here is to process the case of a
11210 type name prefix (current instance case) before handling the case
11211 of interface prefixes.

11218 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11219 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11220 type that is an anonymous access to controlled object, establish
11221 an associated finalization chain to avoid corrupting the global
11222 finalization list when a dynamically allocated object designated
11223 by such a component is deallocated.
11224 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11225 functions that need it, even when not marked Requires_Overriding.
11226 (Initialize_Tag): Replace call to has_discriminants by call to
11227 Is_Variable_Size_Record in the circuitry that handles the
11228 initialization of secondary tags.
11229 (Is_Variable_Size_Record): New implementation.
11230 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11231 Suppress_Initialization pragma for a derived type.
11232 (Is_Variable_Size_Record): New subprogram.
11233 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11234 initial version of this routine and also fixes problems causing
11235 incomplete initialization of the table of interfaces.
11236 (Build_Init_Procedure): Improve the generation of code to initialize the
11237 the tag components of secondary dispatch tables.
11238 (Init_Secondary_Tags): New implementation that simplifies the previous
11239 version of this routine.
11240 (Make_DT): Add parameter to indicate when type has been frozen by an
11241 object declaration, for diagnostic purposes.
11242 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11243 diagnose attemps to freeze a subprogram when some untagged type of its
11244 profile is a private type whose full view has not been analyzed yet.
11245 (Freeze_Array_Type): Generate init proc for packed array if either
11246 Initialize or Normalize_Scalars is set.
11247 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11248 constructing the new profile, copy the null_exclusion indicator for each
11249 parameter, to ensure full conformance of the new body with the spec.
11250
11251 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11252 Create wrappers for constructor functions that need it, even when not
11253 marked Requires_Overriding.
11254 (Covers): Handle properly designated types of anonymous access types,
11255 whose non-limited views are themselves incomplete types.
11256 (Add_Entry): Use an entity to store the abstract operation which hides
11257 an interpretation.
11258 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11259 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11260 initialization aggregate.

11262 Function_Interp_Has_Abstract_Op.
11263 (Has_Compatible_Type): Remove machinery that skips interpretations if
11264 they are labeled as potentially hidden by an abstract operator.
11265 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11266 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11267 (Write_Overloads): Output the abstract operator if present.
11268 (Add_Entry): Before inserting a new entry into the interpretation table
11269 for a node, determine whether the entry will be disabled by an abstract
11270 operator.
11271 (Binary_Op_Interp_May_Be_Hidden): New routine.
11272 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11273 aggregate.
11274 (Function_Interp_May_Be_Hidden): New routine.
11275 (Has_Compatible_Type): Do not consider interpretations hidden by
11276 abstract operators when trying to determine whether two types are
11277 compatible.

11286 types declared in the declarative part of a nested package body or in
11287 the proper body of a stub.
11288 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11289 of the same dispatch table slot to renamed primitives.
11290 (Make_Select_Specific_Data_Table): Handle private types.
11291 (Tagged_Kind): Handle private types.
11292 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11293 output of implicit importation and exportation.
11294 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11295 first formal of the thunk is always associated with the controlling
11296 type. In addition perform the following code cleanup: remove formal
11297 Thunk_Alias which is no longer required, cleanup evaluation of the
11298 the controlling type, and update the documentation.
11299 Replace occurrence of Default_Prim_Op_Count by
11300 Max_Predef_Prims. Addition of compile-time check to verify
11301 that the value of Max_Predef_Prims is correct.
11302 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11303 (Make_DT): Add parameter to indicate when type has been frozen by an
11304 object declaration, for diagnostic purposes.
11305 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11306 construction of statically allocated dispatch tables.
11307 (Make_DT): In case of library-level tagged types export the declaration
11308 of the primary tag. Remove generation of tags (now done by Make_Tags).
11309 Additional modifications to handle non-static generation of dispatch
11310 tables. Take care of building tables for asynchronous interface types
11311 (Make_Tags): New subprogram that generates the entities associated with
11312 the primary and secondary tags of Typ and fills the contents of Access_
11313 Disp_Table. In case of library-level tagged types imports the forward
11314 declaration of the primary tag that will be declared later by Make_DT.
11315 (Expand_Interface_Conversion): In case of access types to interfaces
11316 replace an itype declaration by an explicit type declaration to avoid
11317 problems associated with the scope of such itype in transient blocks.

11321 Javier Miranda <miranda@adacore.com>
11322
11323 * exp_util.ads, exp_util.adb:
11324 This patch replaces a number of occurrences of explicit tests for N_Null
11325 with calls to Known_Null. This improves tracking of null values, since
11326 Known_Null also catches null constants, and variables currently known to
11327 be null, so we get better tracking.
11328 (Ensure_Defined): create an itype reference only in the scope of the
11329 itype.
11330 (Side_Effect_Free): A selected component of an access type that
11331 denotes a component with a rep clause must be treated as not
11332 side-effect free, because if it is part of a linked structure its
11333 value may be affected by a renaming.
11334 (Expand_Subtype_From_Expr): For limited objects initialized with build
11335 in place function calls, do nothing; otherwise we prematurely introduce
11336 an N_Reference node in the expression initializing the object, which
11337 breaks the circuitry that detects and adds the additional arguments to
11338 the called function. Bug found working in the new patch for statically
11339 allocated dispatch tables.
11340 (Is_Library_Level_Tagged_Type): New subprogram.
11341 (Remove_Side_Effects): If the expression of an elementary type is an
11342 operator treat as a function call.
11343 (Make_Literal_Range): If the index type of the array is not integer, use
11344 attributes properly to compute the constraint on the resulting aggregate
11345 which is a string.
11346
11347 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11348 class-wide type whose base type is an incomplete private type, leave
11349 class-wide type unfrozen so that freeze nodes can be generated
11350 properly at a later point.
11351 (Freeze_Entity, array case): Handle case of pragma Pack and component
11352 size attributre clause for same array.

11410 same project when the order of the source dirs are known. Detect
11411 duplicate sources/units in the same project when the order of the
11412 source dirs are not known.

11419 directory of non extending project to nil.
11420 Change type of path name variables to be Path_Name_Type
11421 (Locate_Directory): Make sure that on Windows '/' is converted to '\',
11422 otherwise creating missing directories will fail.

11979 of Set_Item.
11980 (Set_Item): When the new item is an element of the currently allocated
11981 table passed by reference, save a copy on the stack if we're going
11982 to reallocate. Also, in Table.Set_Item, make sure we test the proper
11983 variable to determine whether to call Set_Last.

11997
11998 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11999 derived type with interface progenitors use the analyzed formal as the
12000 parent of the actual, to create renamings for all the inherited
12001 operations in Derive_Subprograms.
12002 (Collect_Previous_Instances): new procedure within of
12003 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12004 unit being loaded, to ensure that the generation of global symbols is
12005 consistent in different compilation modes.
12006 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12007 takes progenitor types into account.
12008 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12009 traversing over the primitives of the formal and actual types to locate
12010 any abstract subprograms of the actual type that correspond to a
12011 nonabstract subprogram of the formal type's ancestor type(s), and issue
12012 an error if such is found.
12013 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12014 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12015 Remove bogus guard around calls to Inherit_Context.
12016 (Reset_Entity): If the entity is the selector of a selected component
12017 that denotes a named number, propagate constant-folding to the generic
12018 template only if the named number is global to the generic unit.
12019 (Set_Instance_Env): Only reset the compilation switches when compiling
12020 a predefined or internal unit.

120222007-08-14 Ed Schonberg <schonberg@adacore.com>
12023
12024 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
12025 parameter to determine whether operation applies to the prefix.
12026 (Complete_Object_Operation): If actual has an access type and
12027 controlling formal is not an in_parameter, reject the actual if it is
12028 an access_to_constant type.
12029 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12030 type, the candidate operations are found in the scope of declaration of
12031 the type, because the type has no primitive subprograms.
12032 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12033 a private extension, only examine visible components before trying to
12034 analyze as a prefixed call.
12035 Change Entity_List to Type_To_Use, for better readability.
12036 (Has_Fixed_Op): Use base type when checking whether the type of an

12045 formal At_Any_Place indicating, when True, that we want to test for
12046 availability of the stream attribute at any place (as opposed to the
12047 current visibility context only).
12048 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12049 purpose of enforcing E.2.2(8) only if it is not available at any place.
12050 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12051 when checking the legality of an extension aggregate in a preelaborable
12052 package. Treat the literal null as a valid default expression in a
12053 component declaration for a type with preelaborable initialization.
12054 A limited interface is a legal progenitor for the designated type of a
12055 remote access to class-wide type.

12067 mark the full view as referenced, to prevent spurious warnings.
12068 (Find_Selected_Component, Has_Components): Handle properly non-limited
12069 views that are themselves incomplete types.
12070 Handle interfaces visible through limited-with clauses.
12071 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12072 subprogram generic actual for which we have generated a renaming.
12073 Warn when the renaming introduces a homonym of
12074 the renamed entity, and the renamed entity is directly visible.

12083 the allocator is not a coextension.
12084 (Resolve): Skip an interpretation hidden by an abstract operator only
12085 when the type of the interpretation matches that of the context.
12086 (Resolve): When looping through all possible interpretations of a node,
12087 do not consider those that are hidden by abstract operators.
12088 (Resolve_Actuals): When verifying that an access to class-wide object
12089 is an actual for a controlling formal, ignore anonymous access to
12090 subprograms whose return type is an access to class_wide type.
12091 (Resolve_Slice): If the prefix of the slice is a selected component
12092 whose type depends on discriminants, build its actual subtype before
12093 applying range checks on the bounds of the slice.
12094 (Valid_Conversion): In an instance or inlined body, compare root types,
12095 to prevent anomalies between private and public views.
12096 (Resolve): Improve error message for ambiguous fixed multiplication
12097 expressions that involve universal_fixed multiplying operations.

12117 elabration statements, register the package with the name server
12118 at the beginning, not at the end, of the elaboration statements so

12330 Add s-osinte-vxworks-kernel.adb to the target pairs of the
12331 kernel run-time lib for VxWorks 6, which would provide a different
12332 implementation for Task_Cont and Task_Stop than the VxWorks 5 version.
12333 x86-solaris section (EH_MECHANISM): Set to -gcc, as this port is now
12334 running ZCX by default.

12862 to compare the sizes.
12863 (convert_vms_descriptor): When converting to a fat pointer type, be

13169
13170 * utils2.c (build_allocator): Provide the extra arguments to
13171 make_aligning_type for super-aligned objects allocated from the default
13172 pool. Leave enough room for a pointer before the aligning field, and
13173 store the system's allocator return value there.
13174 (build_call_alloc_dealloc): When releasing a super-aligned object,
13175 retrieve the system's allocator return value from where build_allocator
13176 has stored it, just ahead of the adjusted address we are passed.
13177 (build_call_raise): Handle properly the generation of line numbers when
13178 the node is marked No_Location.

13206 used.
13207 (Gen_Object_Files_Options): Add formatting of Linker Options, when
13208 Output_Linker_Option_List is set. Suppress this formatting when
13209 Zero_Formatting is set.
13210 Add case for CLI_Target.
13211 (System_Restrictions_Used): New flag, used to avoid generating with of
13212 System_Restrictions and initialization of the data unless there is
13213 some use of System.Restrictions in the partition.
13214 (Check_System_Restrictions_Used): New procedure
13215
13216 * s-stalib.adb: Remove with of System.Restrictions. No longer needed
13217 since we only with this unit in the binder file if it is used elsewhere
13218 in the partition.
13219
132202007-06-06 Vincent Celier <celier@adacore.com>

13236 which the address-clause is applied to in-mode actuals (allowed by
13237 13.1(22)).
13238 (Apply_Discriminant_Check): Do not generate a check if the type is
13239 constrained by a current instance.
13240 (Activate_Division_Check): New procedure
13241 (Activate_Overflow_Check): New procedure
13242 (Activate_Range_Check): New procedure
13243 Call these new Activate procedures instead of setting flags directly
13244 (Apply_Array_Size_Check): Removed, no longer needed.
13245 Code clean up: remove obsolete code related to GCC 2.
13246 (Get_E_Length): Protect against bomb in case scope is standard
13247 (Selected_Range_Checks): If the node to be checked is a conversion to
13248 an unconstrained array type, and the expression is a slice, use the
13249 bounds of the slice to construct the required constraint checks.
13250 Improve NOT NULL error messages
13251 (Apply_Constraint_Check): If the context is a null-excluding access
13252 type, diagnose properly the literal null.
13253
132542007-06-06 Pascal Obry <obry@adacore.com>

13268 Arnaud Charlet <charlet@adacore.com>
13269
13270 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13271 applicable to types that have the With_Type flag set. Returns the
13272 non-limited view of the type, if available, otherwise the type itself.
13273 For class-wide types, there is no direct link in the tree, so we have
13274 to retrieve the class-wide type of the non-limited view of the Etype.
13275 New attributes Static_Initialization and Static_Elaboration_Desired.
13276 Remove the pragma Thread_Body, and the associated flag
13277 Is_Thread_Body in entities, and all related code.
13278 (Suppress_Value_Tracking_On_Call): New flag
13279 E_Exception has Esize and Alignment fields
13280 (Universal_Aliasing): New function.

13284 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
13285 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13286 (Related_Interface): New attribute. Present in dispatch table pointer
13287 components of records. Set to point to the entity of the corresponding
13288 interface type.
13289 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13290 (Original_Access_Type): Remove, not needed.
13291 (Root_Type): Handle properly subtypes of class-wide-types.
13292 Update comments.
13293
13294 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13295 class-wide types visible through limited-with clauses.
13296 (Try_Primitive_Operation): When examining all primitive operations of a
13297 tagged type, do not consider subprograms labeled as hidden unless they
13298 belong to a private generic type with a tagged parent.
13299 (Try_Object_Operation): Extensive rewriting, to handle properly various
13300 overloading cases, when several ancestors may have class-wide operations
13301 that are possible candidates, and when the overloaded functions return
13302 array types and have defaulted parameters so that the call may be
13303 interpreted as an indexing.
13304 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13305 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13306 successive actuals before analyzing the call itself.
13307 (Try_Primitive_Operation): A primitive operation is compatible with the
13308 prefix if the prefix has a synchronized type and the type of the formal
13309 is its corresponding record, as can be the case when the primitive
13310 operation is declared outside of the body of the type.
13311 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13312 perform homonym traversal, looking for class-wide operation matches
13313 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13314 access parameters are now restricted to anonymous access types.
13315 (Mark_Allocator): An allocator with a discriminant association parent is
13316 a coextension.
13317 (Try_One_Prefix_Interpretation): If the type of the object is
13318 incomplete, as can be happen when it is a limited view obtained through
13319 a limited_with_clause, the selected component is not part of a prefixed
13320 call.
13321 (Complete_Object_Operation): Diagnose properly an object that is not
13322 aliased when the corresponding controlling formal is an access
13323 parameter.
13324 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13325 ambiguous calls in prefixed notation, where two primitives differ only
13326 in that the controlling argument of one is an access parameter.
13327
13328 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13329 whether a function that returns an unconstrained type can be inlined.
13330 (Process_Formals): Diagnose properly the illegal use of an incomplete
13331 type in the profile of an access_to_subprogram declaration.
13332 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13333 operations are attached to the corresponding record.
13334 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13335 When processing a primitive of a concurrent type which implements an
13336 interface change the type of all controlling formals to that of the
13337 corresponding record type.
13338 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13339 to determine the tagged type to which a primitive belongs.
13340 (Check_Conventions): Capture condition to ignore a primitive operation
13341 (which is shared between the loop in Check_Conventions and the one in
13342 Check_Convention) in a new local function Skip_Check.
13343 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13344 confusion with Check_Conventions' own Prim_Op local variable.
13345 (Create_Extra_Formals): Test for a tagged result type rather than a
13346 controlling result when determining whether to add a BIP_Alloc_Form
13347 formal and a BIP_Final_List formal to the function.
13348 (Check_Conformance); For parameters that are anonymous access types,
13349 subtype conformance requires that the not null and the constant
13350 indicators must match
13351 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13352 to retrieve the appropriate type when processing a concurrent type
13353 declared within a generic. Minor comment reformatting. Change invocation
13354 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13355 mitive.
13356 (Analyze_Subprogram_Body): If the return type of a function is an
13357 anonymous access to the limited view of a class-wide type, and the
13358 non-limited view of the type is available, update the type of the
13359 function so that code can be generated.
13360 (Process_Formals): In case of access-subtype itype whose designated
13361 type is also an itype (situation that happens now with access to
13362 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13363 attribute to avoid backend problems.
13364 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13365 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13366 anonymous types' designated types are same before testing
13367 Subtypes_Statically_Match.
13368 (Create_Extra_Formals): Test for a named access parameter that is a
13369 controlling formal as an additional condition for adding an
13370 accessibility level formal. This can occur in the subp type created for
13371 dispatching calls in Expand_Dispatching_Call, and allows calling
13372 Create_Extra_Formals from that procedure rather than special-casing the
13373 extra formals there.
13374 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13375 when the function has a controlling result.
13376 (Check_Returns): Add much more knowledge of the optimization of local
13377 raise statements to gotos, to retain proper warnings in this case.
13378 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13379 nodes when looking for last statement.
13380
13381 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13382 class-wide types visible through limited with clauses.
13383 (Add_One_Interp): If the operands are anonymous access types, the
13384 predefined operator on universal_access is immediately visibles
13385 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13386 other anonymous access types.
13387 (Disambiguate): Take into account CIL convention.
13388 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13389
133902007-06-06 Robert Dewar <dewar@adacore.com>
13391
13392 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13393 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13394 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13395 Fix lower bound of tables.
13396 Add rep clauses.
13397
13398 * nlists.adb: Ditto.
13399 (Prev_Node, Next_Node): Change index type to Int so that it properly
13400 covers the range First_Node_Id - 1 up.

13406
13407 * exp_aggr.ads, exp_aggr.adb:
13408 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13409 in extension aggregates.
13410 (Flatten): Other conditions being met, an aggregate is static if the
13411 low bound given by component associations is different from the low
13412 bound of the base index type.
13413 (Packed_Array_Aggregate_Handled): If the component type is itself a
13414 packed array or record, the front-end must expand into assignments.
13415 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13416 Init_Pr, instead of Ancestor_Is_Expression.
13417 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13418 coextension chain root, either generate a list controller or use the
13419 already existing one.
13420 (Static_Array_Aggregate): New procedure to construct a positional
13421 aggregate that can be handled by the backend, when all bounds and
13422 components are compile-time known constants.
13423 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13424 types covering interface types into assignments.
13425 (Replace_Type): move to Build_Record_Aggr_Code.
13426 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13427 interface type, convert to the definite type of the aggregate itself,
13428 so that needed components are visible.
13429 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13430 components and the context is an extended return statement do not
13431 create a transient block for it, to prevent premature finalization
13432 before the return is executed.
13433 (Gen_Assign): Do not generate a call to deep adjust routine if the
13434 component type is itself an array of controlled (sub)-components
13435 initialized with an inner aggregate.
13436 (Component_Check): New name for Static_Check. This name is now more
13437 appropriate, and documentation is added which was missing.
13438 (Component_Check): Add test for bit aligned component value
13439 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13440 Tagged_Comps, name is more appropriate given added function below.
13441 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13445 Robert Dewar <dewar@adacore.com>
13446
13447 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13448 Terminated: Add unchecked type conversion from System.Address to
13449 System.Tasking.Task_Id when calling the predefined primitive
13450 _disp_get_task_id.
13451 Disable new Ada 05 accessibility check for JVM.NET targets, which
13452 cannot be implemented in a practical way.
13453 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13454 the sources always references the tag of the actual object. Therefore,
13455 if 'Tag is applied in the sources to class-wide interface objects we
13456 generate code that displaces "this" to reference the base of the object.
13457 (Expand_N_Attribute_Reference, case Size): Return specified size if
13458 known to front end.
13459 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13460 has code that displaces the pointer of the object to manage interface
13461 types. However this code must not be executed when the prefix is a
13462 subprogram. This bug caused the wrong expansion of the internally
13463 generated assignment that fills the dispatch table when the primitive
13464 is a function returning a class-wide interface type.
13465 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13466 Set_Attribute_Name for Name_Unaligned_Valid.
13467

13470
13471 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13472 If the initialization is the equivalent aggregate of the initialization
13473 procedure of the type, do not remove it.
13474 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13475 initialized to null from having their expression reset to empty and
13476 note this exception in the comment.

13486 references where the prefix must be a simple name.
13487
13488 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13489 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13490 Attribute_Requires_Simple_Name_Prefix.
13491 (Name_Modifies_Prefix): Body of new function.
13492 (Requires_Simple_Name_Prefix): Body of new function.
13493 (Resolve_Attribute, case Access): Improve error message for case of
13494 mismatched conventions.
13495 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13496 incomplete type.
13497 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13498 constrained subtype for a nominal unconstrained type, use its base type
13499 to check for conformance with the context.
13500 (Resolve_Attribute): Remove test of the access type being associated
13501 with a return statement from condition for performing accessibility
13502 checks on access attributes, since this case is now captured by
13503 Is_Local_Anonymous_Access.
13504 (Analyze_Access_Attribute): Set Address_Taken on entity
13505 (Analyze_Attribute, case Address): Set Address_Taken on entity
13506 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13507 validating an access attribute whose prefix is a current instance.
13508 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13509 applied to dispatching operations, if freezing is required then we set
13510 the attribute Has_Delayed_Freeze in the prefix's entity.
13511 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13512 current scope if access of local subprogram taken
13513 (Analyze_Access_Attribute): Check legality of self-reference even if the
13514 expression comes from source, as when a single component association in
13515 an aggregate has a box association.
13516 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13517 the prefix if it is a protected operation and the attribute is
13518 Unrestricted_Access.
13519 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13520 reference to the base type of the context, to force a constraint check
13521 when the context is an access subtype with an explicit constraint.
13522 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13523 node is rewritten as an interface conversion. leave unanalyzed after
13524 resolution, to ensure that type checking against the context will take
13525 place.

13530
13531 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13532 wrapper when the full view of the controlling type of an inherited
13533 function that dispatches on result implements interfaces.
13534 (Expand_N_Object_Declaration): In cases where the type of the
13535 declaration is anonymous access, create finalization list for it.
13536 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13537 if the object has no explicit initialization, to match description of
13538 functionality of pragam Persistent_BSS.
13539 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13540 new function to build static aggregates, to replace initialization call
13541 when static initialization is desired.
13542 (Freeze_Type): Generate a list controller for an access type whenever
13543 its designated type has controlled anonymous access discriminants.
13544 (Build_Equivalent_Aggregate): New procedure to compute a static
13545 aggregate to be used as default initialization for composite types,
13546 instead of a generating a call to the initialization procedure for the
13547 type.
13548 (Build_Initialization_Call): When available, replace a call to the
13549 initialization procedure with a copy of the equivalent static aggregate
13550 for the type.
13551 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13552 declarations for objects of a class-wide interface type, rather than
13553 just identifiers, to prevent visibility problems.
13554 (Expand_N_Object_Declaration): When expanding the declaration for an
13555 object of a class-wide interface type, preserve the homonym chain of
13556 the original entity before exchanging it with that of the generated
13557 renaming declaration.
13558 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13559 active, because there is no way to handle the exception.
13560 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13561 to do a minimum decoration of the Access_Disp_Table list.
13562 (Expand_Record_Controller): Avoid the addition of the controller between
13563 the component containing the tag of a secondary dispatch table and its
13564 adjacent component that stores the offset to the base of the object.
13565 This latter component is only generated when the parent type has
13566 discriminants ---documented in Add_Interface_Tag_Components).
13567 (Apply_Array_Size_Check): Removed, no longer needed.
13568 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13569 components, create a Master_Entity for it only if it contains tasks.
13570 (Build_Init_Procedure): Suppress the tag assignment compiling under
13571 no run-time mode.
13572 (Freeze_Record_Type): Remove code associated with creation of dispatch
13573 table.
13574 (Init_Secondary_Tags): Update type of actuals when generating calls to
13575 Ada.Tags.Set_Offset_To_Top
13576 (Stream_Operation_OK): Disable use of streams compiling under no
13577 run-time mode
13578 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13579 if Has_Init_Expression set.
13580 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13581 Register_Primitive, which provides the same functionality.
13582 (Requires_Init_Proc): Return false in case of interface types.
13583 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13584 cleanup the code.
13585 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13586 is always associated with a predefined primitive because the internal
13587 entities associated with interface types are not predefined primitives.
13588 Therefore, the call to Is_Internal is replaced by a call to the
13589 function Is_Predefined_Dispatching_Operation.
13590 (Make_Eq_If): When generating the list of comparisons for the
13591 components of a given variant, omit the controller component that is
13592 present if the variant has controlled components.

13596 Bob Duff <duff@adacore.com>
13597
13598 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13599 handle the creation of finalization lists and calls for nested
13600 coextensions when the root of the chains is part of a return statement.
13601 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13602 Finalization.
13603 (Expand_Record_Equality): Skip components that are interface types.
13604 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13605 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13606 with Rewrite_Coextension. Change the condition for detecting coextension
13607 root nodes.
13608 (Is_Local_Access_Discriminant): Removed.
13609 (Rewrite_Coextension): New routine which rewrites a static coextension
13610 as a temporary and uses its unrestricted access in the construction of
13611 the outer object.
13612 (Complete_Coextension_Finalization): New routine. Generate finalization
13613 attachment calls to all delayed coextensions.
13614 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13615 the allocator is not a coextension itself and has delayed coextensions.
13616 If the current allocator is controlled, but also a coextension, delay
13617 the generation of the finalization attachment call.
13618 Rename local variable "Node" to "Nod" in order to avoid confusion with
13619 "Elists.Node".
13620 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13621 limited types that are not inherently limited. Such an allocator is
13622 illegal, but is generated by the expander for a return statement, to
13623 copy the result onto the secondary stack. This is the only case where a
13624 limited object can be copied. Generate code to displace the pointer
13625 to the object if the qualified expression is a class-wide interface
13626 object. Such displacement was missing and hence the copy of the object
13627 was wrong.
13628 (Apply_Accessibility_Check): Handle allocated objects initialized in
13629 place.
13630 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13631 and Expand_Allocator_Expression. Allocating class-wide interface objects
13632 this routine displaces the pointer to the allocated object to reference
13633 the component referencing the corresponding secondary dispatch table.
13634 Expand_Allocator_Expression): Add missing support to allocate class-wide
13635 interface objects initialized with a qualified expression.
13636 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13637 function result type, and use the finalization list associated with the
13638 function scope in that case (such an anonymous type should not be
13639 treated like an access parameter's type).
13640

13642 Gary Dismukes <dismukes@adacore.com>
13643 Javier Miranda <miranda@adacore.com>
13644
13645 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13646 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13647 required exception handler.
13648 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13649 properly the case of a function whose return type is a limited
13650 class-wide interface type. Modify the code of the accessibility
13651 check to handle class-wide interface objects. In this case we need to
13652 displace "this" to reference the primary dispatch table to get access
13653 to the TSD of the object (to evaluate its accessibility level).
13654 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13655 rather than a controlling result as one of the conditions for
13656 generating tests of the implicit BIP_Alloc_Form formal. The
13657 initialization assignment is also handled according to whether the
13658 result is tagged instead of controlling.
13659 In the case where the init assignment is inserted in the "then" part of
13660 the allocation conditional, rewrite the target to be a dereference of
13661 the implicit BIP_Object_Access formal.
13662 If the returned value is unconstrained and created on the secondary
13663 stack, mark the enclosing block and function so that the secondary
13664 stack is not reclaimed on return.
13665 Treat returns from functions with controlling results similarly to
13666 returns from functions with unconstrained result subtypes.
13667 If the object returned is unconstrained, and an allocator must be
13668 created for it, analyze the allocator once the block for the extended
13669 return is installed, to ensure that finalizable components
13670 of the expression use the proper finalization list. Guard the call to
13671 Move_Final_List with a check that there is something to finalize.
13672 (Make_Tag_Ctrl_Assignment): Use "old" handling
13673 of controlled type assignment for virtual machines, since new code uses
13674 unsupported features (such as direct access to bytes in memory).
13675
136762007-06-06 Gary Dismukes <dismukes@adacore.com>
13677 Ed Schonberg <schonberg@adacore.com>
13678
13679 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13680 accessibility actual, check for the case of an aliased object that has
13681 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13682 we fall into processing for the attribute rather than the name of the
13683 object.
13684 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13685 formal has its address taken in the body, create a temporary to capture
13686 value. If the return type is a limited interface, do not treat the
13687 return value as Controlled.
13688 (Is_In_Place_Function): If the return type is a limited interface,
13689 treat as returning in place. The actual returned object may not always
13690 be limited, but the caller has to assume that it is returned in place.
13691 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13692 context of an allocator, use the correct finalization chain (that is,
13693 the chain belonging to the access type, rather than the chain belonging
13694 to the current scope).
13695 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13696 result type rather than a controlling result as a precondition for
13697 adding an allocation form actual to a build-in-place call.
13698 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13699 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13700 primitive in the dispatch tables. This work is now done by Make_DT when
13701 the type is frozen.
13702 (Register_Predefined_DT_Entry): Removed.
13703 (Add_Return): If end label is not present, use sloc of last statement
13704 for generated return statement in procedure, for better gdb behavior
13705 on expanded code.
13706 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13707 object address nodes to ensure proper processing by routines like
13708 Insert_After*.
13709 (Expand_Call): Fix generation of validity check for parameter
13710 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13711 the allocation form parameter if the result subtype is constrained,
13712 except when the function has a controlling result.
13713 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13714 rather than Is_Controlled and Has_Controlled_Component, since we want to
13715 include class-wide result types in this treatment. Also test for a
13716 controlling result, since that also requires passing a finalization
13717 list.
13718 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13719 even when the result subtype is constrained, to handle calls involving
13720 controlling results.
13721 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13722 is now called even when the result subtype is constrained, to handle
13723 calls involving controlling results.
13724 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13725 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13726 now performs the test).
13727 (Make_Build_In_Place_Call_In_Object_Declaration):
13728 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13729 constrained, to handle calls involving controlling results.
13730 (Add_Return): Accomodate rewritten pattern from local raise to goto
13731 transformation, so that we still recognize an transfer statement
13732 and do the right thing here in that case.
13733 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13734 and end of subprogram code.
13735 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13736 support for primitives that are functions (without formals) with a
13737 controlling result.
13738 (Inherited_From_Formal): If the actual subtype has not generic parent
13739 type, it is not an actual for a formal derived type, and there is no
13740 operation to inherit from the formal.
13741

13743 Thomas Quinot <quinot@adacore.com>
13744
13745 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13746 inserted cleanup code appropriately for GDB use.
13747 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13748 exception handler for Deep_Adjust or Deep_Finalize.
13749 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13750 Raise_From_Controlled_Operation is available, use a call to that
13751 subprogram instead of a plain "raise Program_Error" node to raise
13752 Program_Error if an exception is propagated from an Adjust or Finalize
13753 operation.
13754 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13755 appears in the optional statement list of a triggering alternative, the
13756 scope actions can be inserted directly there, and not in the list that
13757 includes the asynchronous select itself.
13758

13762
13763 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13764 generated exception handler appropriately when debugging generated code.
13765 Deal properly with No_Exception_Propagation restriction mode.
13766 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13767 System.Address to System.Tasking.Task_Id when processing the result of
13768 the predefined primitive _disp_get_task_id.
13769 (Expand_N_Asynchronous_Select): Clarify comment.
13770 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13771 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13772 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13773 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13774 privals and for generated call to Complete_Entry_Body, for better gdb
13775 behavior.
13776 (Copy_Result_Type): Utility to construct a parameter and result profile
13777 for protected functions whose return type is an anonymous access to
13778 subprogram.
13779 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13780 call the above.
13781 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13782 point when the local-raise-to-goto transformation has taken place.
13783
137842007-06-06 Javier Miranda <miranda@adacore.com>
13785 Nicolas Setton <setton@adacore.com>
13786
13787 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13788 functionality when the backend is generating code.
13789 Otherwise any serious error
13790 reported by the backend calling the frontend routine Error_Msg
13791 changes the Compilation_Mode to Check_Semantics, disables the
13792 functionality of this routine and causes the generation of
13793 spureous additional errors.
13794
13795 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13796 debugging information now generated by the compiler for fat-pointer
13797 types.
13798 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13799 DWARF2/3.
13800 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13801
138022007-06-06 Thomas Quinot <quinot@adacore.com>
13803
13804 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13805 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13806 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13807 For a remote call to a function with a classwide return type, apply an
13808 E.4(18) check to the returned value.
13809 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13810 stream attributes of the designated type of an RACW, as they are not
13811 dispatching primitive operations.
13812
138132007-06-06 Geert Bosch <bosch@adacore.com>
13814
13815 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13816 negative literal
13817 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13818 positive
13819 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13820 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13821 positive
13822 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13823
138242007-06-06 Javier Miranda <miranda@adacore.com>
13825
13826 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13827 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13828
138292007-06-06 Javier Miranda <miranda@adacore.com>
13830
13831 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13832 deallocation of class-wide interface objects.
13833 (Expand_Dispatching_Constructor_Call): Take into account that if the
13834 result of the dispatching constructor is an interface type, the
13835 function returns a class-wide interface type; otherwise the returned
13836 object would be actual. The frontend previously accepted returning
13837 interface types because Expand_Interface_Actuals silently performed
13838 the management of the returned type "as if" it were a class-wide
13839 interface type.
13840 (Expand_Dispatching_Constructor_Call): Replace call to
13841 Make_DT_Access_Action by direct call to Make_Function_Call.
13842
138432007-06-06 Robert Dewar <dewar@adacore.com>
13844 Ed Schonberg <schonberg@adacore.com>
13845
13846 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13847 compute masking constant, since we now set Esize properly to the
13848 underlying size.
13849 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13850 to match the alignment.
13851 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13852 packed arrays of 8 bits or less.
13853
13854 * freeze.adb (Freeze_Entity): When freezing the formals of a
13855 subprogram, freeze the designated type of a parameter of an access type
13856 only if it is an access parameter.
13857 Increase size of C convention enumeration object
13858 (Freeze_Entity, array type case): Make sure Esize value is properly
13859 adjusted for the alignment if it is known.
13860 (Freeze_Entity, array type case): When checking bit packed arrays for
13861 the size being incorrect, check RM_Size, not Esize.
13862 (Freeze_Record_Type): Check for bad discriminated record convention
13863 (In_Exp_Body): Return true if the body is generated for a subprogram
13864 renaming, either an attribute renaming or a renaming as body.
13865 (Check_Itype): If the designated type of an anonymous access component
13866 is a non-protected subprogram type, indicate that it is frozen, to
13867 prevent out-of-scope freeze node at some subsequent call.
13868 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13869 only if the subprogram is neither imported nor exported, as well as the
13870 NCA descriptor class if the subprogram is exported.

13876
13877 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13878 default initialization on an imported object, when there is no
13879 initialization call generated for it.
13880 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13881 restriction
13882
13883 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13884 Static_Elaboration_Desired.
13885 Remove pragma Thread_Body.
13886 Implement a new pragma No_Body
13887 Removes the Explicit_Overriding pragma
13888 Remove Optional_Overriding pragma
13889 (Prag): Deal with Universal_Aliasing.
13890 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13891 Pragma_CIL_Constructor): New names.
13892
13893 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13894 uses the equivalent aggregate of a type must be treated as an implicit
13895 initialization.
13896 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13897 has none of the other categories.
13898 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13899 to apply Import to an object renaming declaration.
13900
13901 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13902 from a C++ class should be declared as limited and that it will be
13903 considererd limited.
13904 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13905 should be declared as limited and that it will be considererd limited.
13906 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13907 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13908 (Analyze_Pragma): Deal with Universal_Aliasing.
13909 (Sig_Flags): Likewise.
13910 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13911 (Overflow_Checks_Unsuppressed): New flag.
13912 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13913 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13914 case of JVM or .NET targets, and compiling user code.
13915 Add debugging convenience routine rv

139172007-06-06 Robert Dewar <dewar@adacore.com>
13918
13919 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that

13933 subtype from the function call, as is done for private types.
13934 (Side_Effect_Free): An expression that is the renaming of an object or

14257 to simplify handling of formal interfaces that derive from other formal
14258 interfaces.

14266 generic ancestor is an interface, create a generic actual for the
14267 corresponding record.

14269 declaration, to ensure that the interface list is processed correctly.
14270 (Inline_Instance_Body): If enclosing scope is an instance body, remove
14271 its entities from visibiility as well.
14272 (Pre_Analyze_Actuals): if the actual is an allocator with constraints
14273 given with a named association, analyze the expression only, not the
14274 discriminant association itself.
14275 (Reset_Entity): If the analysis of a selected component is transformed
14276 into an expanded name in the prefix of a call with parameters, do not
14277 transform the original node into an expanded name, to prevent visibility
14278 errors in the case of nested generics.
14279 (Check_Private_View): For an array type, check whether the index types
14280 may need exchanging.

14407 to Void.
14408 (Find_Type_Of_Object): In the case of an access definition, always set
14409 Is_Local_Anonymous_Access. We were previously not marking the anonymous

14428 improve the condition that avoids inheriting the components associated
14429 with secondary tags of the parent.

14450 * sem_aggr.adb (Resolve_Record_Aggregate): Ignore internal components
14451 of the type that specify the position of interface tags when the type
14452 inherits discriminated array components from the parent type.
14453 If a component is initialized with a box, check for the presence of a
14454 default expression in its declaration before using its default
14455 initialization procedure.
14456 (Resolve_Record_Aggregate): If a component is box-initialized, and the
14457 component type has a discriminants, create a partial aggregate for it
14458 by copying the discriminants of the component subtype.
14459 Reject attempt to initialize a discriminant with a box.
14460 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
14461 associated with dispatch tables is known at compile time.

14475 not null indicator.
14476
14477 * par-ch3.adb (P_Known_Discriminant_Part_Opt, P_Component_Items): If

14556 unimplemented unit.
14557 (Analyze_With_Clause): Recognize use of GNAT.Exception_Traces in a
14558 manner similar to GNAT.Current_Exception. This is a violation of
14559 restriction (No_Exception_Propagation), and also inhibits the
14560 optimization of local raise to goto.
14561 (Analyze_With_Clause): Check for Most_Recent_Exception being with'ed,
14562 and if so set Most_Recent_Exception_Used flag in Opt, and also check

14578 protected type does not implement a task interface or a nonlimited
14579 interface.
14580 (Analyze_Task_Type): Rearrange and simplify code for testing that a task
14581 type does not implement a protected interface or a nonlimited interface.

14586 routines if the expander is not active.
14587 (Analyze_Task_Body): Mark all handlers to stop optimization of local
14588 raise, since special things happen for task exception handlers.

14651 Do_Division_Check flag explicitly.
14652 (Resolve_Actuals): If the actual is of a synchronized type, and the
14653 formal is of the corresponding record type, this is a call to a
14654 primitive operation of the type, that is declared outside of the type;
14655 the actual must be unchecked-converted to the type of the actual
14656 (Resolve_Call): Kill all current values for any subprogram call if
14657 flag Suppress_Value_Tracking_On_Call is set.
14658 (Resolve_Type_Conversion): Generate error message the the operand
14659 or target of interface conversions come from a limited view.
14660 (Check_Infinite_Recursion): Ignore generated calls
14661 (Check_Allocator_Discrim_Accessibility): New procedure for checking
14662 that an expression that constrains an access discriminant in an

14725 function's result type to determine the level of the return object's
14726 type.
14727 (Build_Elaboration_Entity): Build name of elaboration entity from the

15566 in prefix form.
15567 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15568 the master of the created object is the innermost enclosing statement.

15705 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
15706 stubbed procedure with a null body, replace the call with a null
15707 statement without using the full inlining machinery, for efficiency
15708 and to avoid invalid values in source file table entries.
15709
15710 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Add support for

15817 that use (a subtype of) the class-wide type of the enclosing type.

15851 to private type.
15852 (Analyze_Subtype_Declaration): For an access subtype declaration, create

15950 run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
15951
15952 * exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
15953 accessibility on class-wide allocators if the allocator occurs at the
15954 same scope level as the allocator's type. The check is guaranteed to
15955 succeed in that case, even when the expression originates from a
15956 parameter of the containing subprogram.
15957 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15958 under No_Dispatching_Calls restriction. During the semantic analysis
15959 we already notified such violation.
15960 (Tagged_Membership): Constant folding. There is no need to check
15961 the tag at run-time if the type of the right operand is non
15962 class-wide abstract.
15963 Replace call to Is_Ancestor by call to Is_Parent
15964 to support concurrent types with interface types.
15965 (Expand_N_Allocator): Add an assertion associated with the generation
15966 of the master_id.
15967 (Expand_N_Slice): Do not enable range check to nodes associated
15968 with the frontend expansion of the dispatch table.
15969 (Is_Local_Access_Discriminant): Subsidiary function to
15970 Expand_N_Allocator.
15971 (Tagged_Membership): Replace generation of call to the run-time
15972 subprogram CW_Membership by call to Build_CW_Membership.
15973 (Expand_Allocator_Expression): Replace generation of call to the
15974 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
15975
15976 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15977 initialize most the TSD components by means of an aggregate.
15978 Modify the declaration of the object containing the TSD
15979 because we now expand code that has a higher level of abstraction.
15980 The TSD has a discriminant containing the Inheritance Depth Level,
15981 value that is used in the membership test but also to fix the size
15982 of the table of ancestors.
15983 (Expand_Interface_Conversion): Insert function body at the closest place
15984 to the conversion expression, to prevent access-before-elaboration
15985 errors in the backend.
15986 Code improved to reduce the size of the dispatch table if
15987 compiling under restriction No_Dispatching_Calls plus code cleanup.
15988 Code reorganization plus removal of calls to Set_Num_Prim_Ops
15989 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
15990 (Expand_Dispatching_Call): Minor code reorganization plus addition of
15991 code to return immediately if compiling under No_Dispatching_Calls
15992 restriction.
15993 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
15994 CPP_Virtual and CPP_Vtable are no longer supported.
15995 (Expand_Interface_Conversion): Add missing support for interface type
15996 derivations.
15997 (Expand_Interface_Actuals): Replace calls to Is_Ancestor by calls to
15998 Is_Parent to support concurrent types with interfaces.
15999 (Init_Predefined_Interface_Primitives): Removed.
16000 (Make_Secondary_DT): Modified to support concurrent record types.
16001 (Set_All_DT_Position): Modified to support concurrent record types.
16002 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
16003 with Get_External_Tag, Inherit_TSD, Set_External_Tag.

16005 with CW_Membership.
16006 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
16007 with Get_Access_Level, Get_Predefined_Prim_Op_Address,
16008 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,

16010 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
16011 (Expand_Dispatching_Call): Replace generation of call to the run-time
16012 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
16013 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
16014 Address.
16015 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
16016 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
16017 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
16018 Build_Set_Prim_Op_Address.
16019 (Get_Remotely_Callable): Subprogram removed.
16020 (Init_Predefined_Interface_Primitives): Replace generation of call to
16021 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16022 Prims.
16023
16024 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16025 First (Parameter_Associations ()) with the call to First_Actual that
16026 returns an actual parameter expression for both named and positional
16027 associations.
16028
16029 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
16030 check violation of restriction No_Dispatching_Calls.
16031 (Check_Controlling_Type): A formal of a tagged incomplete type is a
16032 controlling argument.
16033
16034 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
16035 First/Next_Component_Or_Discriminant
16036 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
16037 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16038 specify Any_Limited_Interface, and this functionality is already
16039 provided by the function Has_Abstract_Interfaces.
16040 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16041 support concurrent types implementing interfaces.
16042 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16043 specify kind Any_Limited_Interface, and this functionality is already
16044 provided by the function Has_Abstract_Interfaces.
16045 (Remove_Side_Effects): replace Controlled_Type by
16046 CW_Or_Controlled_Type whenever the issue is related to
16047 using or not the secondary stack.
16048
16049 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16050 P_Interface_Type_Definition to fulfill the new interface (the formal
16051 Is_Synchronized is no longer required).
16052
16053 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
16054 Update dependencies.
16055

16061
16062 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
16063 anonymous, use finalization list of enclosing dynamic scope.
16064 (Expand_N_Package_Declaration): For a library package declaration
16065 without a corresponding body, generate RACW subprogram bodies in the
16066 spec (just as we do for the task activation call).
16067 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
16068 Is_Abstract_Type. Make sure these are called only when appropriate.
16069 Remove all code for DSP option
16070 (CW_Or_Controlled_Type): new subprogram.

16074 Gary Dismukes <dismukes@adacore.com>
16075
16076 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
16077 parameter. If it is set to true, return a result capped according to
16078 the global upper bound for the index of an entry family.
16079 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
16080 (Build_Find_Body_Index): Adjust for above change.
16081 (Entry_Index_Expression): Likewise.
16082 (Is_Potentially_Large_Family): New function extracted from...
16083 (Collect_Entry_Families): ...here. Call it to detect whether the family
16084 is potentially large.
16085 (Build_Entry_Count_Expression): If the family is potentially large, call
16086 Family_Size with 'Cap' set to true.
16087 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16088 a protected version of an operation declared in the private part of
16089 a protected object, because they may be invoked through a callback.
16090 (Set_Privals): If the type of a private component is an anonymous access
16091 type, do not create a new itype for each protected body.
16092 If the body of a protected operation creates
16093 controlled types (including allocators for class-widetypes), the
16094 body of the corresponding protected subprogram must include a
16095 finalization list.
16096 (Build_Activation_Chain_Entity): Build the chain entity for extended
16097 return statements.
16098 (Type_Conformant_Parameters): Use common predicate Conforming_Types
16099 to determine whether operation overrides an inherited primitive.
16100 (Build_Wrapper_Spec): Add code to examine the parents while looking
16101 for a possible overriding candidate.
16102 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16103 hold an actual parameter value since its initialization is separated
16104 from the the declaration. Prevents errors on null-excluding access
16105 formals.

16108 Pablo Oliveira <oliveira@adacore.com>
16109
16110 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16111 Do an Unchecked_Conversion to handle the passage from the Underlying
16112 Type to the Base Type when calling Build_To_Any_Call and
16113 Build_From_Any_Call.
16114 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16115 E_Constant, depending upon Variable formal.
16116 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16117 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16118 parameter that requires an extra constrained parameter, declare
16119 temporary for actual as a variable, not a constant.
16120 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16121 the unit being compiled is the one that contains the stub type.
16122 Change primitive operation name for the RACW associated with a RAS
16123 from Call to _Call so it cannot clash with any legal identifier.
16124 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16125 Is_RAS.
16126 (Append_RACW_Bodies): New subprogram.
16127 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16128 Add_Receiving_Stubs_To_Declarations functions.
16129 When expanding a package body, this list correspond to the
16130 statements in the HSS at the end of the pacakge.
16131 When expanding a package spec, this list correspond to the
16132 spec declarations.
16133 (Add_Receiving_Stubs_To_Declarations): Append the function
16134 registering the receiving stubs at the end of the 'Stmts' list.
16135 (RCI_Package_Locator): Pass the new Version generic formal when
16136 instantiating a RCI_Locator package.
16137 (Build_From_Any_Function): To compute the High bound for an
16138 unconstrained array actual, we add the Low bound with the length.
16139 Thus we must convert the low bound and the length to an appropriate
16140 type before doing the sum.
16141 (Build_Subprogram_Receiving_Stubs, PolyORB):
16142 * Retrieve the extra formals parameters at the
16143 end of the parameter stream.
16144 * Use Move_Any_Value to write back out parameters
16145 after executing the request as it is more efficient
16146 than Copy_Any_Value.
16147 * Build the any containing Extra Formals with the
16148 appropriate typecode.
16149 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16150 empty Component_List.
16151 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

16155 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16156 Use Build_Actual_Object_Declaration to prepare the actuals.
16157 (Add_Parameter_To_NVList): Set the parameter mode to In for
16158 Extra Constrained Parameters.
16159 (Build_General_Calling_Stubs): Set the parameter type to boolean for
16160 Extra Constrained parameters.
16161 (Build_To_Any_Function, Build_From_Any_Function,
16162 Built_TypeCode_Function): When Typ is implicit, call the correct
16163 function with the first not implicit parent type.
16164 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16165 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16166 typecode from the Etype. Therefore we retrieve the correct typecode
16167 with a call to Get_Any_Type.
16168 (Copy_Specification): Do controlling formal type substitution based on
16169 Is_Controlling_Formal flag, instead of caller-provided object type.
16170 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16171 a RACW primitive operation, we might get a subprogram declaration for an
16172 ancestor of the RACW designated type (not for the designated type
16173 itself), in the case where this operation is inherited. In this case we
16174 have no easy means of determining the original tagged type for which
16175 the primitive was declared, so instead we now rely on
16176 Copy_Specification to use the Is_Controlling_Formal flag to determine
16177 which formals require type substitution.

16182 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
16183 GNAT.Current_Exception are not allowed if pragma Restrictions
16184 (No_Exception_Propagation) is set and in any case make the associated
16185 handler unsuitable as a target for a local raise statement.
16186 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16187 run-time subprogram CW_Membership by call to Build_CW_Membership.
16188 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16189 by a function call, a temporary must be created before expanding the
16190 Constructor_Call itself, to prevent out-of-order elaboration in the
16191 back-end when stack checking is enabled..
16192
161932007-04-06 Ed Schonberg <schonberg@adacore.com>

16209 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
16210 an association with a box as providing a value even though the
16211 initialization procedure for the type is not available.
16212 (Resolve_Record_Aggregate): Check that a choice of an association with a
16213 box corresponds to a component of the type.
16214 (Resolve_Record_Aggregate): Split Is_Abstract flag into
16215 Is_Abstract_Subprogram and Is_Abstract_Type.
16216
16217 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
16218 assert.
16219

16272 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
16273 Add gnatstack to the list of commands that use project file related
16274 switches, and get the single attribute Switches from the stack package
16275 in a project file when calling gnatstack. Parse the -U flag for
16276 processing files belonging to all projects in the project tree.
16277 Remove all processing for command Setup
16278
16279 * prj-attr.adb: Add new package Stack with single attribute Switches
16280
16281 * vms_conv.ads (Command_Type): Add command Stack.

16317
16318 * mingw32.h (S2WSU): New macro to convert from a string to a
16319 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16320 standard 8bits encoding.
16321 (WS2SU): As above but converting from wide-sring to string.
16322 This is needed as it is necessary to have access to both versions in the
16323 runtime for the form parameter encoding support.
16324 This set of patch add support for the encoding form parameter.
16325 (S2WS): Improve implementation to handle cases where the filename is not
16326 UTF-8 encoded. In this case we default to using the current code page
16327 for the conversion.
16328
16329 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16330 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match
16331 the constants defined in adaint.h.

16333 (freopen): Idem.
16334
16335 * s-ficobl.ads (AFCB): Add Encoding field to record the filename
16336 encoding. This is needed for the Reset routine (freopen low level-call).

16373
16374 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16375 __gnat_adjust_context_for_raise.
16376 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16377 implementation of floating point operations as native x86 targets.
16378 So the FPU should be initialized in the same way using finit. Fix
16379 floating point operations accuracy issues.
16380 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16381 member in struct sigaction, so as to avoid warning for incompatible
16382 pointer types.

16398
16399 * lib-xref.ads, lib-xref.adb:
16400 Modify the loop that collects type references, to include interface
16401 types that the type implements. List each of these interfaces when
16402 building the entry for the type.
16403 (Generate_Definition): Initialize component Def and Typ of new entry
16404 in table Xrefs, to avoid to have these components unitialized.
16405 (Output_References): Split Is_Abstract flag into
16406 Is_Abstract_Subprogram and Is_Abstract_Type.
16407 (Generate_Reference): Add barrier to do not generate the warning

164482007-04-06 Robert Dewar <dewar@adacore.com>
16449
16450 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16451 it no longer destroys the contents of Name_Buffer or Name_Len and
16452 non-standard and invalid names are handled better.
16453 (Get_Decoded_Name_String): Improve performance by using

16467 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16468 illegal in Ada 95, in cases where it is legal. Change the warnings to
16469 errors in other cases. Don't give the error unless the "not null"
16470 parses properly. Correct the source position at which the error occurs.
16471 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16472 P_Null_Exclusion, to suppress "not null" warnings.
16473 (P_Identifier_Declarations): Code cleanup. Removed unrequired label and
16474 associated goto statements.
16475
16476 * par-endh.adb (Pop_End_Context): Allow more flexibility in placement
16477 of END RECORD

16514 Shared_Library_Minimum_Options,
16515 Shared_Library_Prefix, Shared_Library_Suffix, Symbolic_Link_Supported.

16525
16526 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16527 switches, without repetition of "eD". Make sure that last character of
16528 -gnatep= switch is not taken as -gnat switch character.
16529 Complete rewrite of circuit for handling saving compilation options
16530 Occasioned by need to support dot switchs for -gnatw, but cleans up
16531 things in general.
16532 -gnatX does not affect Ada_Version
16533 Include -gnatyA in -gnatg style switches
16534

165452007-04-06 Vincent Celier <celier@adacore.com>
16546
16547 * prj-ext.adb (Initialize_Project_Path): New procedure that initialize
16548 the default project path, initially done during elaboration of the
16549 package.
16550 If the prefix returned by Sdefault is null, get the prefix from a call
16551 to Executable_Prefix_Path.
16552 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16553 null.
16554
16555 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16556 canonical directory name to open the directory from which files are
16557 retrieved.
16558 (Record_Other_Sources): Idem.
16559 (Locate_Directory): Add the possibility to create automatically missing
16560 directories when Setup_Projects is True.

16562 Setup_Projects is True, for object dir, library dir, library ALI dir,
16563 library source copy dir and exec dir.
16564
16565 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older

166002007-04-06 Ed Falis <falis@adacore.com>
16601
16602 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16603 full word is no longer compared twice.
16604
166052007-04-06 Ed Schonberg <schonberg@adacore.com>
16606
16607 * sem_ch10.adb (Install_Limited_Context_Clauses.
16608 Expand_Limited_With_Clause): Use a new copy of selector name in the
16609 call to Make_With_Clause. This fixes the tree structure for ASIS
16610 purposes. Nothing is changed in the compiler behaviour.
16611 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16612 a package renaming.
16613 (Install_Limited_With_Clauses): Do not install non-limited view when it
16614 is still incomplete.
16615
166162007-04-06 Ed Schonberg <schonberg@adacore.com>
16617 Gary Dismukes <dismukes@adacore.com>
16618
16619 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16620 when capturing size information, instead of base type, which for a
16621 formal array type will be the unconstrained type.
16622 (Analyze_Formal_Object_Declaration): Add check for illegal default
16623 expressions for a formal in object of a limited type.
16624 (Instantiate_Object): Ditto.
16625 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16626 because they were defaulted in the formal package and no check applies
16627 to them.
16628 (Check_Formal_Package_Instance): Extend conformance check to other
16629 discrete types beyond Integer.
16630 (Process_Default): Copy directly the unmatched formal. A generic copy
16631 has already been performed in Analyze_Formal_Package.
16632 (Analyze_Associations): If a formal subprogram has no match, check for
16633 partial parametrization before looking for a default, to prevent
16634 spurious errors.
16635 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16636 not set the instantiation environment before analyzing the actuals.
16637 Fixes regression on 8515-003 with implementation of AI-133.
16638 Set_Instance_Env checks whether the generic unit is a predefined
16639 unit, in which case the instance must be analyzed with the latest Ada
16640 mode. This setting must take place after analysis of the actuals,
16641 because the actuals must be analyzed and frozen in the Ada mode extant
16642 outside of the current instantiation.
16643 (Save_Env, Restore_Env): Preserve and restore the configuration
16644 parameters so that predefined units can be compiled in the proper Ada
16645 mode.
16646 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16647 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16648 and Is_Abstract_Type.
16649 (Analyze_Formal_Package): For better error recovery, Add exception
16650 handler to catch Instantion_Error, which can be raised in
16651 Analyze_Associations

16654 Bob Duff <duff@adacore.com>
16655 Gary Dismukes <dismukes@adacore.com>
16656
16657 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16658 prefix type is a discriminated subtype of the type of the formal.
16659 (Analyze_Allocator): Collect all coextensions regardless of the context.
16660 Whether they can be allocated statically is determined in exp_ch4.
16661 (Analyze_Selected_Component): If the prefix is a limited view and the
16662 non-limited view is available, use the non-limited one.
16663 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16664 therefore illegal), suggest a qualified expression rather than a type
16665 conversion, because a type conversion would be illegal in this context.
16666 (Anayze_Allocator): Trace recursively all nested allocators so that all
16667 coextensions are on the corresponding list for the root. Do no mark
16668 coextensions if the root allocator is within a declaration for a stack-
16669 allocated object, because the access discriminants will be allocated on
16670 the stack as well.
16671 (Analyze_Call): Remove restriction on calls to limited functions for the
16672 cases of generic actuals for formal objects, defaults for formal objects
16673 and defaults for record components.
16674 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16675 element list. Their expansion is delayed until the enclosing allocator
16676 is processed and its finalization list constructed.
16677 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16678 for an operation with the given name among the primitive operations of
16679 the corresponding record type.
16680 (Analyze_Selected_Component): If the prefix is a task type that
16681 implements an interface, and there is no entry with the given name,
16682 check whether there is another primitive operation (e.g. a function)
16683 with that name.
16684 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16685 properly the indexing of a function call written in prefix form, where
16686 the function returns an array type, and all parameters of the function
16687 except the first have defaults.
16688 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16689 the original operands, rather than relocating them, for efficiency and
16690 to work properly when an operand is overloaded.
16691 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16692 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16693 (Analyze_Selected_Component): If the prefix is a private extension, only
16694 scan the visible components, not those of the full view.
16695 (Try_Primitive_Operation): If the operation is a procedure, collect all
16696 possible interpretations, as for a function, because in the presence of
16697 classwide parameters several primitive operations of the type can match
16698 the given arguments.
16699

16701 Robert Dewar <dewar@adacore.com>
16702
16703 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16704 tag-indeterminate call to an abstract function, when the left-hand side
16705 is not classwide.
16706 (Analyze_Loop_Statement): Improve detection of infinite loops
16707
167082007-04-06 Ed Schonberg <schonberg@adacore.com>
16709 Thomas Quinot <quinot@adacore.com>
16710
16711 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16712 out of Analyze_Package_Declaration, because processing must be applied
16713 to package bodies as well, for deferred constants completed by pragmas.
16714 (Analyze_Package_Declaration): When the package declaration being
16715 analyzed does not require an explicit body, call Check_Completion.
16716 (May_Need_Implicit_Body): An implicit body is required when a package
16717 spec contains the declaration of a remote access-to-classwide type.
16718 (Analyze_Package_Body): If the package contains RACWs, append the
16719 pending subprogram bodies generated by exp_dist at the end of the body.
16720 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16721 Is_Abstract_Subprogram and Is_Abstract_Type.
16722 (Preserve_Full_Attributes): The full entity list is not an attribute
16723 that must be preserved from full to partial view.
16724
16725 * sem_dist.adb (Add_RAS_Dereference_TSS):
16726 Change primitive name to _Call so it cannot clash with any legal
16727 identifier, and be special-cased in Check_Completion.
16728 Mark the full view of the designated type for the RACW associated with
16729 a RAS as Comes_From_Source to get proper view switching when installing
16730 private declarations.
16731 Provite a placeholder nested package body along with the nested spec
16732 to have a place for Append_RACW_Bodies to generate the calling stubs
16733 and stream attributes.
16734

16736 Robert Dewar <dewar@adacore.com>
16737
16738 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16739 that is a limited view, check the non-limited view if available.
16740 (Undefined): Refine error message for missing with of Text_IO
16741 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16742 to distinguish real missing with cases.
16743 Fix format of all missing with messages
16744 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16745 renaming as body when renamed entity is abstract.
16746
167472007-04-06 Ed Schonberg <schonberg@adacore.com>
16748 Javier Miranda <miranda@adacore.com>
16749
16750 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16751 predicate recursive, to handle complex expressions on literals whose
16752 spurious ambiguity comes from the abstract interpretation of some
16753 subexpression.
16754 (Interface_Present_In_Ancestor): Add support to concurrent record
16755 types.
16756 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16757 Is_Abstract_Subprogram and Is_Abstract_Type.
16758
167592007-04-06 Ed Schonberg <schonberg@adacore.com>
16760 Javier Miranda <miranda@adacore.com>
16761
16762 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16763 dereference of a local object R created as a reference to another
16764 object O, use the access level of O.
16765 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16766 rather than local Same_Formal_Type, to check whether protected operation
16767 overrides an inherited one.
16768 (Same_Formal_Type): New predicate, used when matching signatures of
16769 overriding synchronized operations, to handle the case when a formal
16770 has a type that is a generic actual.

17414 alignment of a field in a variant record might not be accurate. Add a

17594 Priority_Specific_Dispatching pragma appearing anywhere in the current
17595 partition. The input argument is the priority number, and the result
17596 is the upper case first character of the policy name.
17597 (__gnat_set_globals): Now a dummy function.
17598 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
17599 mechargs instead of sigargs, as the latter can be retrieved from the

17646 sem_util and renamed as Collect_All_Abstract_Interfaces.
17647 (Set_All_DT_Position): Hidden entities associated with abstract
17648 interface primitives are not taken into account in the check for

17660 alias of a predefined dispatching primitive.
17661 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17662 compiling under full ABI compatibility mode we avoid the generation of
17663 calls to run-time services that fill the dispatch tables because under
17664 this mode we currently inherit the dispatch tables in the IP subprogram.
17665 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17666 (Expand_Interface_Conversion): Use an address as the type of the formal
17667 of the internally built function that handles the case in which the
17668 target type is an access type.

17851 default initialization.
17852 (Make_OK_Assignment_Statement): If the expression is of the form
17853 Typ'Acc, where Acc is an access attribute, the expression comes from a
17854 default initialized self-referential component.
17855 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17856 that has been derived from several abstract interfaces we must also

17869 target, pass the Valid attribute applied to a floating-point prefix on

17872 the allocated storage when it is specified by a per-object expression.
17873 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17874 Nothing to do here, the attribute has been rewritten during semantic

17878 (Find_Fat_Info): Handle case of universal real

17885 subcomponent's enclosing variable is aliased with a constrained subtype.
17886 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17887 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17888 an aliased prefix must be known to be constrained in order to use True
17889 for the attribute value, and now it's possible for some aliased views
17890 to be unconstrained.

17902
17903 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17904 register in the final list objects containing class-wide interfaces;
17905 otherwise we incorrectly register the tag of the interface in the final
17906 list.
17907 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17908 generate the wrapper if the parent primitive is abstract. This is
17909 required to report the correct error message.
17910 (Expand_N_Subtype_Indication): Do validity checks on range
17911 (Clean_Task_Names): If an initialization procedure includes a call to
17912 initialize a task (sub)component, indicate that the procedure will use

17915 compatibility for interfacing with CPP by default.
17916 (Expand_N_Object_Declaration): Only build an Adjust call when the

17920 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17921 Object_Declaration to the call.
17922 (Freeze_Type): When the designated type of an RACW was not frozen at the
17923 point where the RACW was declared, validate the primitive operations
17924 with respect to E.2.2(14) when it finally is frozen.
17925 (Build_Initialization_Call,Expand_Record_Controller): Rename
17926 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17927 return-by-reference has no meaning in Ada 2005.
17928 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17929 to register tag of the immediate ancestor interfaces in the
17930 run-time structure.
17931 (Init_Secondary_Tags): Moved to the specification to allow the
17932 initialization of extension aggregates with abstract interfaces.
17933 (Build_Master_Renaming): Make public, for use by function declarations
17934 whose return type is an anonymous access type.
17935 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17936 Insert_List_Before_And_Analyze after the generation of the specs
17937 associated with null procedures.
17938 (Expand_Tagged_Root): Update documentation in its specification.
17939 (Init_Secondary_Tags): Update documentation.
17940 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17941 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17942 then generate code to inherit the contents of the dispatch table
17943 directly from the ancestor.
17944 (Expand_Record_Controller): Insert controller component after tags of
17945 implemented interfaces.
17946 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17947 create null procedure overridings when null procedures are inherited
17948 from interfaces.
17949 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17950 declarations for overriding null primitives inherited from interfaces.
17951 (Is_Null_Interface_Procedure): New function in
17952 Make_Null_Procedure_Specs.
17953 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17954 immediate ancestor of a tagged type is an abstract interface type we
17955 must generate the specification of the predefined primitives associated
17956 with controlled types (because the dispatch table of the ancestor is
17957 null and hence these entries cannot be inherited). This is required to
17958 elaborate well the dispatch table.

17970 (Expand_N_Allocator): For "new T", if the object is constrained by
17971 discriminant defaults, allocate the right amount of memory, rather than
17972 the maximum for type T.
17973 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17974 when the allocator is initialized by a build-in-place call, since the
17975 allocator is already rewritten as a reference to the function result,
17976 and this prevents an unwanted duplication of the function call.
17977 Add with and use of Exp_Ch6.
17978 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17979 is a call to build-in-place function and apply
17980 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17981 untagged designated types).
17982 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17983 optimization if source or target is biased.
17984 (Expand_N_Allocator): Add comments for case of an allocator within a
17985 function that returns an anonymous access type designating tasks.
17986 (Expand_N_Allocator): apply discriminant checks for access
17987 discriminants of anonymous access types (AI-402, AI-416)
17988
179892006-10-31 Bob Duff <duff@adacore.com>
17990 Robert Dewar <dewar@adacore.com>
17991 Gary Dismukes <dismukes@adacore.com>
17992 Ed Schonberg <schonberg@adacore.com>
17993
17994 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17995
17996 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17997 (Expand_N_Assignment_Statement): Call
17998 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17999 build-in-place function call. Currently, this can happen only for
18000 assignments that come from aggregates.
18001 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18002 in order to alleviate the upward compatibility introduced by AI-318.
18003 (Expand_N_Extended_Return_Statement): Add support for handling the
18004 return object as a build-in-place result.
18005 (Expand_Non_Function_Return): Implement simple return statements nested
18006 within an extended return.
18007 (Enable_New_Return_Processing): Turn on the new processing of return
18008 statements.
18009 (Expand_Non_Function_Return): For a return within an extended return,
18010 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18011 (Expand_N_Extended_Return_Statement): Implement AI-318
18012 (Expand_Simple_Function_Return): Ditto.
18013 (Expand_N_If_Statement): Handle new -gnatwt warning
18014 (Expand_N_Case_Statement): Handle new -gnatwt warning
18015 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18016 a protected object.
18017 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18018 validity checking of assignments to elementary record components.
18019 (Expand_N_Return_Statement): return Class Wide types on the secondary
18020 stack independantly of their controlled status since with HIE runtimes,
18021 class wide types are not potentially controlled anymore.
18022
18023 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18024 node kind.
18025
18026 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18027 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18028 it expects a block, procedure, or task. The return statement will get
18029 turned into a block, and Expand_Cleanup_Actions will happen then.
18030
180312006-10-31 Robert Dewar <dewar@adacore.com>
18032 Ed Schonberg <schonberg@adacore.com>
18033 Bob Duff <duff@adacore.com>
18034 Gary Dismukes <dismukes@adacore.com>
18035
18036 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18037 capability.
18038 (Expand_Inlined_Call): Tagged types are by-reference types, and
18039 therefore should be replaced by a renaming declaration in the expanded
18040 body, as is done for limited types.
18041 (Expand_Call): If this is a call to a function with dispatching access
18042 result, propagate tag from context.
18043 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18044 CPP by default.
18045 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18046 build-in-place when the right-hand side of an assignment is a
18047 build-in-place function call.
18048 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18049 of the explicit dereference of the allocator to the result subtype of
18050 the build-in-place function. This is needed to satisfy type checking
18051 in cases where the caller's return object is created by an allocator for
18052 a class-wide access type and the type named in the allocator is a
18053 specific type.
18054 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18055 conversion of the reference to the declared object to the result subtype
18056 of the build-in-place function. This is needed to satisfy type checking
18057 in cases where the declared object has a class-wide type. Also, in the
18058 class-wide case, change the type of the object entity to the specific
18059 result subtype of the function, to avoid passing a class-wide object
18060 without explicit initialization to the back end.
18061 (Register_Interface_DT_Entry): Moved outside the body of
18062 Freeze_Subprogram because this routine is now public; it is called from
18063 Check_Dispatching_Overriding to handle late overriding of abstract
18064 interface primitives.
18065 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18066 adding an implicit access actual on a call to a build-in-place function.
18067 (Expand_Actuals): Test for an actual parameter that is a call to a
18068 build-in-place function and apply
18069 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18070 (Is_Build_In_Place_Function): New function to determine whether an
18071 entity is a function whose calls should be handled as build-in-place.
18072 (Is_Build_In_Place_Function_Call): New function to determine whether an
18073 expression is a function call that should handled as build-in-place.
18074 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18075 calls to build-in-place functions as the initialization of an allocator.
18076 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18077 handling calls to build-in-place functions in contexts that do not
18078 involve init of a separate object (for example, actuals of subprogram
18079 calls).
18080 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18081 handling calls to build-in-place functions as the initialization of an
18082 object declaration.
18083 (Detect_Infinite_Recursion): Add explicit parameter Process to
18084 instantiation of Traverse_Body to avoid unreferenced warning.
18085 (Check_Overriding_Inherited_Interfaces): Removed.
18086 (Register_Interface_DT_Entry): Code cleanup.
18087 (Register_Predefined_DT_Entry): Code cleanup.
18088 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18089 inlined statements if within a transient scope.
18090 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18091 formal parameters with occurrences of actuals in inlined body, establish
18092 visibility on the proper view of the actual's subtype for the body's
18093 context.
18094 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18095 compatibility mode and we have an imported CPP subprogram because
18096 for now we assume that imported CPP primitives correspond with
18097 objects whose constructor is in the CPP side (and therefore we
18098 don't need to generate code to register them in the dispatch table).
18099 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18100 aligned selected component.
18101 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18102 the actual of an in-mode parameter is a type conversion.
18103 (Expand_Actuals): If the call does not come from source and the actual
18104 is potentially misaligned, let gigi handle it rather than rejecting the
18105 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18106 Class Wide types as returning by reference independantly of their
18107 controlled status since with HIE runtimes class wide types are not
18108 potentially controlled anymore.
18109
181102006-10-31 Ed Schonberg <schonberg@adacore.com>
18111
18112 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
18113 references that are private components of the protected object.
18114 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
18115 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18116 instantiation to deal with warnings.
18117 (Initialize_Protection): If expression for priority is non-static, use
18118 System_Priority as its expected type, in case the expression has not
18119 been analyzed yet.
18120
181212006-10-31 Robert Dewar <dewar@adacore.com>
18122
18123 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18124 initialization of Homonym_Len.
18125 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18126 names from fully qualified name. Fixes problem of duplicate
18127 external names differing only in the presence of such a block name.
18128
181292006-10-31 Thomas Quinot <quinot@adacore.com>
18130 Pablo Oliveira <oliveira@adacore.com>
18131
18132 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18133 subprogram Ids, even if they are not yet assigned.
18134 (Build_Subprogram_Id): It is now this function that will take care of
18135 calling Assign_Subprogram_Ids if necessary.
18136 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18137 should be done only once they are assigned.
18138 (Build_From_Any_Function, case of tagged types): Add missing call to
18139 Allocate_Buffer.
18140 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18141 type for an RACW type.
18142 (Add_RACW_Features): When processing an RACW declaration for which the
18143 designated type is already frozen, enforce E.2.2(14) rules immediately.
18144 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18145 special reordering of controlling formals.
18146
18147 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18148 associated stub type for an RACW type.
18149
181502006-10-31 Ed Schonberg <schonberg@adacore.com>
18151
18152 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18153 fixed-point operations in an integer context, i.e. as operands of a
18154 conversion to an integer type, indicate that result must be rounded.
18155
181562006-10-31 Robert Dewar <dewar@adacore.com>
18157
18158 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18159 cases, pass the encoding method, since it is now required by the run
18160 time.
18161
18162 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18163 assumption that Str'First = 1.
18164 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18165 it on to the Value_Wide_Wide_Character call.
18166 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18167 properly handles a string of the form quote-encoded_wide_char-quote.
18168
18169 * s-wchcnv.adb: Minor reformatting
18170
181712006-10-31 Javier Miranda <miranda@adacore.com>
18172
18173 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18174 run-time membership test to ensure that the constructed object
18175 implements the target abstract interface.
18176
181772006-10-31 Robert Dewar <dewar@adacore.com>
18178
18179 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18180 Machine_Attribute pragma internally to implement the user pragma.
18181 Add processing for pragma Interface so that it is now completely
18182 equivalent to pragma Import.
18183
18184 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18185 so that it can be applied to all entities, including record components
18186 and enumeration literals.
18187 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18188 priority ranges are correct, verify compatibility against task
18189 dispatching and locking policies, and if everything is correct an entry
18190 is added to the table containing priority specific dispatching entries
18191 for this compilation unit.
18192 (Delay_Config_Pragma_Analyze): Delay processing
18193 Priority_Specific_Dispatching pragmas because when processing the
18194 pragma we need to access run-time data, such as the range of
18195 System.Any_Priority.
18196 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18197 Allow pragma Unreferenced as a context item
18198 Add pragma Preelaborable_Initialization
18199 (Analyze_Pragma, case Interface): Interface is extended so that it is
18200 now syntactically and semantically equivalent to Import.
18201 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18202 insertion characters.
18203 Add handling for Pragma_Wide_Character_Encoding
18204 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18205 never supercedes a real restriction, and that a real restriction
18206 always supercedes a warning.
18207 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
18208 appropriate form.
18209
182102006-10-31 Bob Duff <duff@adacore.com>
18211 Ed Schonberg <schonberg@adacore.com>
18212 Robert Dewar <dewar@adacore.com>
18213
18214 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18215 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18216 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18217 in Ada 2005.
18218 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18219 type of the function containing a return statement, because the
18220 Return_Type field was removed. We now use the Return_Applies_To field.
18221
18222 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18223 (Build_Task_Image_Decl): If procedure is not called from an
18224 initialization procedure, indicate that function that builds task name
18225 uses the sec. stack. Otherwise the enclosing initialization procedure
18226 will carry the indication.
18227 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18228 N_Object_Declaration instead.
18229 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18230 conditional dead code killed, and change implementation accordingly.
18231 (Insert_Actions): Add N_Return_Object_Declaration case.
18232 Correct comment to mention N_Extension_Aggregate node.
18233 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18234 attempts to save information for global variables which cannot be
18235 safely tracked.
18236 (Get_Current_Value_Condition): Handle conditions the other way round
18237 (constant on left). Also handle right operand of AND and AND THEN
18238 (Set_Current_Value_Condition): Corresponding changes
18239 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18240 (Get_Current_Value_Condition): Handle simple boolean operands
18241 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18242 (Get_Current_Value_Condition): If the variable reference is within an
18243 if-statement, does not appear in the list of then_statments, and does
18244 not come from source, treat it as being at unknown location.
18245 (Get_Current_Value_Condition): Enhance to allow while statements to be
18246 processed as well as if statements.
18247 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18248 come from source.
18249 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18250 of loop. This is safe now that we fixed Kill_Current_Values.
18251 (OK_To_Do_Constant_Replacement): Check whether current scope is
18252 Standard, before examining outer scopes.
18253
182542006-10-31 Vincent Celier <celier@adacore.com>
18255
18256 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18257 When True, apply VMS treatment to children of packages A, G, I and S.
18258 For F320-016
18259
18260 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18261
182622006-10-31 Robert Dewar <dewar@adacore.com>
18263 Ed Schonberg <schonberg@adacore.com>
18264
18265 * freeze.adb: Add handling of Last_Assignment field
18266 (Warn_Overlay): Supply missing continuation marks in error msgs
18267 (Freeze_Entity): Add check for Preelaborable_Initialization
18268
18269 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18270
18271 * g-expect.adb: Add Warnings (Off) to prevent new warning
18272
18273 * lib-xref.adb: Add handling of Last_Assignment field
18274 (Generate_Reference): Centralize handling of pragma Obsolescent here
18275 (Generate_Reference): Accept an implicit reference generated for a
18276 default in an instance.
18277 (Generate_Reference): Accept a reference for a node that is not in the
18278 main unit, if it is the generic body corresponding to an subprogram
18279 instantiation.
18280
18281 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18282
18283 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18284 -gnatwq/Q.
18285 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18286 exception handler.
18287 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18288 use clauses, to avoid messages on packages used to qualify, and also
18289 to avoid messages from obsolescent units.
18290 (Warn_On_Useless_Assignments): Don't generate messages for imported
18291 and exported variables.
18292 (Warn_On_Useless_Assignments): New procedure
18293 (Output_Obsolescent_Entity_Warnings): New procedure
18294 (Check_Code_Statement): New procedure
18295
18296 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18297 Change name Is_Ada_2005 to Is_Ada_2005_Only
18298 (Last_Assignment): New field for useless assignment warning
18299
183002006-10-31 Olivier Hainque <hainque@adacore.com>
18301
18302 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18303 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18304
183052006-10-31 Bob Duff <duff@adacore.com>
18306 Robert Dewar <dewar@adacore.com>
18307 Ed Schonberg <schonberg@adacore.com>
18308
18309 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18310 Ada 95 mode, because it violates the new rules for AI-318.
18311
18312 * g-awk.ads: Use overloaded subprograms in every case where we used to
18313 have a default of Current_Session. This makes the code closer to be
18314 correct for both Ada 95 and 2005.
18315
18316 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18317 code, relying on the fact that the compiler generates a warning
18318 instead of an error in -gnatg mode.
18319
18320 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18321 E_Return_Statement entity kind.
18322 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18323
18324 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18325 report an error if the reserved word abstract has been previously found.
18326 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18327
18328 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18329 parenthesized range attribute usage
18330 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18331
18332 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18333 in the syntax for extended_return_statement. This is not in the latest
18334 RM, but the ARG is expected to issue an AI allowing this.
18335 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18336 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18337 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18338 P_Return_Statement): Parse the new syntax for extended_return_statement.
18339
18340 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18341 Output_End_Missing): Add error-recovery code for the new
18342 extended_return_statement syntax; that is, the new E_Return entry on
18343 the scope stack.
18344
18345 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18346 limited to nonlimited, because otherwise we violate the new Ada 2005
18347 rules about returning limited types in function Create_AST_Handler in
18348 s-asthan.adb.
18349
18350 * sem.adb (Analyze): Add cases for new node kinds
18351 N_Extended_Return_Statement and N_Return_Object_Declaration.
18352
18353 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18354 type is in the same category as type of context before applying check,
18355 to prevent anomalies in instantiations.
18356 (Resolve_Aggregate): Remove test for limited components in aggregates.
18357 It's unnecessary in Ada 95, because if it has limited components, then
18358 it must be limited. It's wrong in Ada 2005, because limited aggregates
18359 are now allowed.
18360 (Resolve_Record_Aggregate): Move check for limited types later, because
18361 OK_For_Limited_Init requires its argument to have been resolved.
18362 (Get_Value): When copying the component default expression for a
18363 defaulted association in an aggregate, use the sloc of the aggregate
18364 and not that of the original expression, to prevent spurious
18365 elaboration errors, when the expression includes function calls.
18366 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18367 were missing. We also didn't handle qualified expressions. Now also
18368 allow function calls. Use new common routine OK_For_Limited_Init.
18369 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18370 with space can upper case letter).
18371
18372 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18373 Has_Static_Discriminants flag
18374 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18375 type with discriminants.
18376 (Process_Range_Expr_In_Decl): Do validity checks on range
18377 (Build_Discriminant_Constraints): Use updated form of
18378 Denotes_Discriminant.
18379 (Process_Subtype): If the subtype is a private subtype whose full view
18380 is a concurrent subtype, introduce an itype reference to prevent scope
18381 anomalies in gigi.
18382 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18383 Record_Type_Declaration): The functionality of the subprograms
18384 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18385 is now performed by a single routine.
18386 (Build_Derived_Record_Type): If the type definition includes an explicit
18387 indication of limitedness, then the type must be marked as limited here
18388 to ensure that any access discriminants will not be treated as having
18389 a local anonymous access type.
18390 (Check_Abstract_Overriding): Issue a detailed error message when an
18391 abstract subprogram was not overridden due to incorrect mode of its
18392 first parameter.
18393 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18394 synchronized private extension declarations. Verify that the ancestor is
18395 a limited or synchronized interface or in the generic case, the ancestor
18396 is a tagged limited type or synchronized interface and all progenitors
18397 are either limited or synchronized interfaces.
18398 Derived_Type_Declaration): Check for presence of private extension when
18399 dealing with synchronized formal derived types.
18400 Process_Full_View): Enchance the check done on the usage of "limited" by
18401 testing whether the private view is synchronized.
18402 Verify that a synchronized private view is completed by a protected or
18403 task type.
18404 (OK_For_Limited_Init_In_05): New function.
18405 (Analyze_Object_Declaration): Move check for limited types later,
18406 because OK_For_Limited_Init requires its argument to have been resolved.
18407 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18408 in order to alleviate the upward compatibility introduced by AI-318.
18409 (Constrain_Corresponding_Record): If the constraint is for a component
18410 subtype, mark the itype as frozen, to avoid out-of-scope references to
18411 discriminants in the back-end.
18412 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18413 this subprogram against wrong sources.
18414 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18415 discriminant of limited type completed with a protected type, when the
18416 discriminant is used to constrain a private component of the type, and
18417 expansion is disabled.
18418 (Find_Type_Of_Object): Do not treat a return subtype that is an
18419 anonymous subtype as a local_anonymous_type, because its accessibility
18420 level is the return type of the enclosing function.
18421 (Check_Initialization): In -gnatg mode, turn the error "cannot
18422 initialize entities of limited type" into a warning.
18423 (OK_For_Limited_Init): Return true for generated nodes, since it
18424 sometimes violates the legality rules.
18425 (Make_Incomplete_Declaration): If the type for which an incomplete
18426 declaration is created happens to be the currently visible entity,
18427 preserve the homonym chain when removing it from visibility.
18428 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18429 inherited subprograms.
18430 (Access_Definition): If this is an access to function that is the return
18431 type of an access_to_function definition, context is a type declaration
18432 and the scope of the anonymous type is the current one.
18433 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18434 incomplete subtype to the set of private dependents of the original
18435 incomplete type.
18436 (Constrain_Discriminated_Type): Emit an error message whenever an
18437 incomplete subtype is being constrained.
18438 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18439 corresponding subtype of the full view of the original incomplete type.
18440 (Check_Incomplete): Properly detect invalid usage of incomplete types
18441 and subtypes.

18475
184762006-10-31 Vincent Celier <celier@adacore.com>
18477
18478 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18479 call it with -static-libgcc, as there are some platforms, such as
18480 Darwin, where one of these two switches is compulsory to link.
18481
184822006-10-31 Vincent Celier <celier@adacore.com>
18483
18484 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18485 instead of ADA_PROJECT_PATH, for the project path.
18486 (Gnatls): When displaying the project path directories, use host dir
18487 specs.
18488
18489 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18490 names in the project path, as absolute paths may correspond to
18491 multi-valued VMS logical names.
18492
184932006-10-31 Vincent Celier <celier@adacore.com>
18494
18495 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18496 absolute path name.
18497 (Locate_Regular_File): Ditto
18498 (Change_Dir): Remove, no longer used
18499 (Normalize_Pathname): Do not use Change_Dir to get the drive letter

18523
18524 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18525 variant records
18526 (Layout_Variant_Record): Retrieve the discriminants from the entity
18527 rather than from the type definition, because in the case of a full
18528 type for a private type we need to take the discriminants from the
18529 partial view.
18530 (Layout_Component_List): When applying the Max operator to variants with
18531 a nonstatic size, check whether either operand is static and scale that
18532 operand from bits to storage units before applying Max.
18533 (Layout_Type): In VMS, if a C-convention access type has no explicit
18534 size clause (and does not inherit one in the case of a derived type),
18535 then the size is reset to 32 from 64.
18536
185372006-10-31 Vincent Celier <celier@adacore.com>
18538
18539 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18540 its file has already been loaded, according to the unit being loaded,
18541 not to the current value of Multiple_Unit_Index.
18542
185432006-10-31 Thomas Quinot <quinot@adacore.com>
18544 Eric Botcazou <ebotcazou@adacore.com>

18571 * mlib-utl.adb (Initialized): Remove, no longer used
18572 (Initialize): Remove, no longer used
18573 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18574 if there is one, the archive indexer. Fail if the archive builder cannot
18575 be found.
18576 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18577 be found.
18578
185792006-10-31 Ed Schonberg <schonberg@adacore.com>
18580
18581 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18582 Process_Body_Clauses): If the context of a body includes a use clause
18583 for P.Q then a with_clause for P in the same body is not redundant,
18584 even if the spec also has a with_clause on P.
18585 Add missing continuation mark to error msg
18586 (Build_Limited_Views): A limited view of a type is tagged if its
18587 declaration includes a record extension.
18588 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18589 node, even if the subunit has errors. This avoids malfunction by
18590 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18591 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18592 generation of obsolescent messages for with statements (cannot do
18593 this too early, or we cannot implement avoiding the messages in the
18594 case of obsolescent units withing obsolescent units).
18595 (Install_Siblings): If the with_clause is on a remote descendant of
18596 an ancestor of the current compilation unit, find whether there is
18597 a sibling child unit that is immediately visible.
18598 (Remove_Private_With_Clauses): New procedure, invoked after completing
18599 the analysis of the private part of a nested package, to remove from
18600 visibility the private with_clauses of the enclosing package
18601 declaration.
18602 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18603 now centralized in Generate_Reference.
18604 (Install_Limited_Context_Clauses): Remove superfluous error
18605 message associated with unlimited view visible through use
18606 and renamings. In addition, at the point in which the error
18607 is reported, we add the backslash to the text of the error
18608 to ensure that it is reported as a single error message.
18609 Use new // insertion for some continuation messages
18610 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18611 to create implicit with_clause for parent unit mentioned in original
18612 limited_with_clause.
18613 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18614 unit is a child unit. For ASIS queries.
18615 (Analyze_Subunit): If the subunit appears within a child unit, make all
18616 ancestor child units directly visible again.

18628 Add the new actual Abstract_Present to every call to
18629 P_Interface_Type_Definition.
18630 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18631 a formal object declaration with an access definition or a subtype mark
18632 with a null exclusion.
18633 (P_Generic_Association): Handle association with box, and others_choice
18634 with box, to support Ada 2005 partially parametrized formal packages.

18639 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18640 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18641 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).

18643 private extensions.
18644 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18645 to P_Interface_Type_Definition.
18646 (P_Interface_Type_Definition): Addition of one formal to report an error
18647 if the reserved word abstract has been previously found.
18648 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18649 object renaming declaration with an access definition or subtype mark
18650 with a possible null exclusion.
18651
18652 * par-ch9.adb: Minor error msg fix
18653
18654 * par-load.adb: Add missing continuation mark to error msg
18655

18673
18674 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18675 on VMS, change "__" to '.' before checking the name.
18676 (Record_Ada_Source): Always add the source file name in the list of
18677 of sources, even if it is not the first time, as it is for another
18678 source index.
18679 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18680 dot, instead of replacing only the first '_'.
18681
18682 * prj-part.adb (Parse): Convert project file path to canonical form
18683
18684 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18685 extended, the project id of the project extending it is recorded in its

18694 Robert Dewar <dewar@adacore.com>
18695
18696 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18697 only a restriction warning is active for the given restriction. This is
18698 desirable because we do not want to modify code in the case where only
18699 a warning is set.
18700 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18701 causes overriding of real restrictions.
18702 Take advantage of new No_Restrictions constant.
18703
18704 * raise.h: (__gnat_set_globals): Change profile.

18733 (OK_Self_Reference): New subprogram to check the legality of an access
18734 attribute whose prefix is the type of an enclosing aggregate.
18735 Generalizes previous mechanism to handle attribute references nested
18736 arbitrarily deep within the aggregate.
18737 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18738 can appear in an aggregate if this is a default-initialized aggregate
18739 for a self-referential type.
18740 (Resolve_Attribute, case Access): Ditto.
18741 Add support for new implementation defined attribute Stub_Type.
18742 (Eval_Attribute, case Attribute_Stub_Type): New case.
18743 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18744 (Stream_Attribute_Available): Implement using new subprogram from
18745 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18746 Has_Specified_Stream_Attribute flag.
18747 Disallow Storage_Size and Storage_Pool for access to subprogram
18748 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18749 access types of return subtypes in extended return statements. Remove
18750 accessibility checks on anonymous access types when Unchecked_Access is
18751 used.
18752 (Analyze_Attribute): Add support for the use of 'Class to convert
18753 a class-wide interface to a tagged type.
18754 Add support for the attribute Priority.
18755 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18756 whether the designated type is discriminated with a constrained partial
18757 view and require static matching in that case.
18758 Add local variable Des_Btyp. The Designated_Type
18759 of an access to incomplete subtype is either its non-limited view if
18760 coming from a limited with or its etype if regular incomplete subtype.
18761
18762 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18763 Fix predicate to identify and allow cases of (expander-generated)
18764 references to tag of designated object of a RACW.
18765 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18766 non-static, and therefore cannot appear as a primary in a preelaborable
18767 package.
18768 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18769 Has_Read_Write_Attributes.
18770 (Has_Read_Write_Attributes): Reimplement in termes of
18771 Has_Stream_Attribute_Definition.
18772 (Missing_Read_Write_Attributes): When checking component types in a
18773 record, unconditionally call Missing_Read_Write_Attributes recursively
18774 (remove guard checking for Is_Record_Type / Is_Access_Type).
18775
187762006-10-31 Robert Dewar <dewar@adacore.com>
18777
18778 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for

18789 for ASIS uses.
18790 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18791 generated private extension declaration if the formal derived type is
18792 synchronized. Carry synchronized present over to the generated private
18793 extension.
18794 (Validate_Derived_Type_Instance): Ensure that the actual of a
18795 synchronized formal derived type is a synchronized tagged type.
18796 (Instantiate_Formal_Package): When creating the instantiation used to
18797 validate the actual package of a formal declared without a box, check
18798 whether the formal itself depends on a prior actual.
18799 (Instantiate_Formal_Subprogram): Create new entities for the defining
18800 identifiers of the formals in the renaming declaration, for ASIS use.
18801 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18802 a renaming declaration or a subtype declaration for an actual in an
18803 instance, capture location information of declaration in generic, for
18804 ASIS use.
18805 (Instantiate_Formal_Package): Add comments on needed additional tests.
18806 AI-317 (partial parametrization) is fully implemented.
18807 (Validate_Private_Type_Instance): Add check for actual which
18808 must have preelaborable initialization
18809 Use new // insertion for some continuation messages
18810 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18811 Default_Expression. Add type retrieval when the declaration has an
18812 access definition. Update premature usage of incomplete type check.
18813 (Check_Access_Definition): New subsidiary routine. Check whether the
18814 current compilation version is Ada 05 and the supplied node has an
18815 access definition.
18816 (Instantiate object): Alphabetize local variables. Handle the creation
18817 of new renaming declarations with respect to the kind of definition
18818 used - either an access definition or a subtype mark. Guard against
18819 unnecessary error message in the context of anonymous access types after
18820 they have been resolved. Add check for required null exclusion in a
18821 formal object declaration.
18822 (Switch_View): A private subtype of a non-private type needs to be
18823 switched (the base type can have been switched without its private
18824 dependents because of the last branch of Check_Private_View.
18825 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18826 value from BT.
18827 (Instantiate_Type): Emit an error message whenever a class-wide type of
18828 a tagged incomplete type is used as a generic actual.
18829 (Find_Actual_Type): Extend routine to handle a component type in a child
18830 unit that is imported from a formal package in a parent.
18831 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18832 agree on constrainedness, rather than checking against ultimate ancestor
18833 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18834 generic body, for navigation purposes.

18837 Thomas Quinot <quinot@adacore.com>
18838
18839 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18840 type.
18841 (New_Stream_Subprogram): When processing an attribute definition clause
18842 for a stream-oriented subprogram, record an entity node occurring at
18843 the point of clause to use for checking the visibility of the clause,
18844 as defined by 8.3(23) as amended by AI-195.
18845 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18846 New_Stream_Function and New_Stream_Procedure.
18847 (New_Stream_Function, New_Stream_Procedure): Removed.
18848 (Analyze_Attribute_Definition_Clause, case Address): Check new
18849 Alignment_Check check

18853 Robert Dewar <dewar@adacore.com>
18854
18855 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18856 generate the same errors compiling under -gnatc.
18857 (Try_Object_Operation): If no candidate interpretation succeeds, but
18858 there is at least one primitive operation with the right name, report
18859 error in call rather than on a malformed selected component.
18860 (Analyze_Selected_Component): If the prefix is an incomplete type from
18861 a limited view, and the full view is available, use the full view to
18862 determine whether this is a prefixed call to a primitive operation.
18863 (Operator_Check): Verify that a candidate interpretation is a binary
18864 operation before checking the type of its second formal.
18865 (Analyze_Call): Add additional warnings for function call contexts not
18866 yet supported.
18867 (Analyze_Allocator): Move the check for "initialization not allowed for
18868 limited types" after analyzing the expression. This is necessary,
18869 because OK_For_Limited_Init looks at the structure of the expression.
18870 Before analysis, we don't necessarily know what sort of expression it
18871 is. For example, we don't know whether F(X) is a function call or an
18872 indexed component; the former is legal in Ada 2005; the latter is not.
18873 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18874 were missing. We also didn't handle qualified expressions. Now also
18875 allow function calls. Use new common routine OK_For_Limited_Init.
18876 (Analyze_Type_Conversion): Do not perform some legality checks in an
18877 instance, because the error message will be redundant or spurious.
18878 (Analyze_Overloaded_Selected_Component): Do not do style check when
18879 setting an entity, since we do not know it is the right entity yet.
18880 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18881 (Analyze_Overloaded_Selected_Component): Same change
18882 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18883 since regular incomplete subtypes are transformed into corresponding
18884 subtypes of their full views.
18885 (Complete_Object_Operation): Treat name of transformed subprogram call
18886 as coming from source, for browsing purposes.
18887 (Try_Primitive_Operation): If formal is an access parameter, compare
18888 with base type of object to determine whether it is a primitive
18889 operation.
18890 (Operator_Check): If no interpretation of the operator matches, check
18891 whether a use clause on any candidate might make the operation legal.
18892 (Try_Class_Wide_Operation): Check whether the first parameter is an
18893 access type whose designated type is class-wide.

18898
18899 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
18900 warn on infinite loops.
18901 Add \\ to some continuation messages
18902 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18903 (Process_Bounds): If the bounds are integer literals that result from
18904 constant-folding, and they carry a user-defined type, preserve that type
18905 rather than treating this as an integer range.
18906 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18907 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18908 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18909 left hand side of assignment.
18910 (Analyze_Assignment): Add suport to manage assigments to the attribute
18911 priority of a protected object.
18912 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18913 not just identifiers.
18914 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18915 or AND THEN for possible tracking.
18916 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18917 case of while loops so we can track values in the loop body.

18921 Bob Duff <duff@adacore.com>
18922
18923 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18924 procedure cannot be a protected operation (it is a basic_declaration,
18925 not a subprogram_declaration).
18926 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18927 Subp. Add logic for entry processing.
18928 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18929 Determine whether an entry or subprogram of a protected or task type
18930 override an inherited primitive of an implemented interface.
18931 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18932 Update the actual used in calls to Check_Overriding_Indicator.
18933 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18934 generate the proper reference to the parent unit, for cross-reference.
18935 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18936 Is_Formal.
18937 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18938 (Add_Extra_Formal): Revise procedure to allow passing in associated
18939 entity, scope, and name suffix, and handle setting of the new
18940 Extra_Formals field.
18941 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18942 pass new parameters. Add support for adding the new extra access formal
18943 for functions whose calls are treated as build-in-place.
18944 (Analyze_A_Return_Statement): Correct casing in error message.
18945 Move Pop_Scope to after Analyze_Function_Return, because an extended
18946 return statement really is a full-fledged scope. Otherwise, visibility
18947 doesn't work right. Correct use of "\" for continuation messages.
18948 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18949 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18950 the node doesn't get properly marked as analyzed.
18951 (Analyze_Subprogram_Body): If subprogram is a function that returns
18952 an anonymous access type that denotes a task, build a Master Entity
18953 for it.
18954 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18955 proper usage of null exclusion in a result definition.
18956 (Process_Formals): Code cleanup and new error message.
18957 (Process_Formals): Detect incorrect application of null exclusion to
18958 non-access types.
18959 (Conforming_Types): Handle conformance between [sub]types and itypes
18960 generated for entities that have null exclusions applied to them.
18961 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18962 base type is an access subtype. This case arrises with null exclusions.
18963 (New_Overloaded_Entity): Do not remove the overriden entity from the
18964 homonym chain if it corresponds with an abstract interface primitive.
18965 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18966 call to the synthesized predicate Is_Incomplete_Type.
18967 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18968 primitives.
18969 (Analyze_Subprogram_Declaration): Check that abstract interface
18970 primitives are abstract or null.
18971 (Analyze_Subprogram_Specification): Remove previous check for abstract
18972 interfaces because it was not complete.
18973 (Has_Interface_Formals): Removed.

18976 Javier Miranda <miranda@adacore.com>
18977
18978 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18979 of Analyze_Package_Body, to create Itype references for anonymous
18980 access types created in the package declaration, whose designated types
18981 may have only a limited view.
18982 (Analyze_Package_Specification): For the private part of a nested
18983 package, install private_with_clauses of enclosing compilation unit if
18984 we are in its visible part.
18985 (Declare_Inherited_Private_Subprograms): Complete barrier
18986 to ensure that the primitive operation has an alias to some parent
18987 primitive. This is now required because, after the changes done for the
18988 implementation of abstract interfaces, the contents of the list of
18989 primitives has entities whose alias attribute references entities of
18990 such list of primitives.
18991 (Analyze_Package_Specification): Simplify code that handles parent units
18992 of instances and formal packages.
18993 (Uninstall_Declarations): Check the convention consistency among
18994 primitive overriding operations of a tagged record type.

19000
19001 * sem_ch8.adb: Minor error msg rewording
19002 (Undefined): When checking for misspellings, invert arguments (to get
19003 expected and found set right)
19004 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
19005 (Analyze_Generic_Renaming): Same fix
19006 (Use_One_Package): Do not take into account the internal entities of
19007 abstract interfaces during the analysis of entities that are marked
19008 as potentially use-visible.
19009 (Find_Type): Handle the case of an attribute reference for
19010 implementation defined attribute Stub_Type (simply let the analysis of
19011 the attribute reference rewrite it).
19012 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
19013 type that appears in a Use_Type clause.
19014 (Analyze_Object_Renaming): Add support for renaming of the Priority
19015 attribute.
19016 (Find_Type): In Ada 2005, a task type can be used within its own body,
19017 when it appears in an access definition.
19018 (Analyze_Object_Renaming): Remove warning on null_exclusion.
19019 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19020 in a formal object declaration or in a subtype declaration.
19021 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19022 (Check_Null_Exclusion): New local routine to
19023 Analyze_Subprogram_Renaming. Check whether the formals and return
19024 profile of a renamed subprogram have required null exclusions when
19025 their counterparts of the renaming already impose them.
19026 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19027 Determine whether an entity is inside a generic scope.
19028 (In_Open_Scope): First pass of documentation update.
19029 (Find_Expanded_Name): Add support for shadow entities associated with
19030 limited withed packages. This is required to handle nested packages.
19031 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
19032 that makes a renaming of a limited withed package illegal.

19036
19037 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
19038 Check_Overriding_Indicator.
19039 (Analyze_Task_Definition): Ditto.
19040 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19041 (Check_Overriding_Indicator): To find overridden interface operation,
19042 examine only homonyms that have an explicit subprogram declaration, not
19043 inherited operations created by an unrelated type derivation.
19044 (Check_Overriding_Indicator): When checking for the presence of "null"
19045 in a procedure, ensure that the queried node is a procedure
19046 specification.
19047 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
19048 type when the formal is an access to variable.
19049 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19050 (Analyze_Task_Type): Same addition
19051 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
19052 provide navigation capabilities for entries.

19059 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
19060 inherited from an interface ancestor by another interface in the
19061 context of an instance as 'late'.
19062 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
19063 of a call to a function that dispatches on access result.
19064 (Check_Dispatching_Operation): In case of late overriding of a primitive
19065 that covers abstract interface subprograms we register it in all the
19066 secondary dispatch tables associated with abstract interfaces.
19067 (Check_Dispatching_Call): Add check that a dispatching call is not made
19068 to a function with a controlling result of a limited type. This is a
19069 current implementation restriction.
19070 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
19071 (Check_Dispatching_Operation): Do no emit a warning if the controlling
19072 argument is an interface type that is a generic formal.
19073 (Is_Interface_Subprogram): Removed.
19074 (Check_Dispatching_Operation): If the subprogram is not a dispatching
19075 operation, check the formals to handle the case in which it is
19076 associated with an abstract interface type.

190862006-10-31 Robert Dewar <dewar@adacore.com>
19087
19088 * sem_eval.adb (Compile_Time_Compare): Make use of information from
19089 Current_Value in the conditional case, to evaluate additional
19090 comparisons at compile time.

19094 Javier Miranda <miranda@adacore.com>
19095
19096 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
19097 subprogram type to provide better diagnostics in case of ambiguity.
19098 (Covers): Handle coverage of formal and actual anonymous access types in
19099 the context of generic instantiation.
19100 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
19101 abstract interface types; this is required to handle concurrent types
19102 with discriminants and abstract interface types.
19103 (Covers): Include type coverage of both regular incomplete subtypes and
19104 incomplete subtypes of incomplete type visibles through a limited with
19105 clause.

19114 (Overrides_Synchronized_Primitive): New function.
19115 (Denotes_Discriminant): Extend predicate to apply to task types.
19116 Add missing continuation marks in error msgs
19117 (Unqualify): New function for removing zero or more levels of
19118 qualification from an expression. There are numerous places where this
19119 ought to be used, but we currently only deal properly with zero or one
19120 level.
19121 (In_Instance); The analysis of the actuals in the instantiation of a
19122 child unit is not within an instantiation, even though the parent
19123 instance is on the scope stack.
19124 (Safe_To_Capture_Value): Exclude the case of variables that are
19125 renamings.
19126 (Check_Obsolescent): Removed
19127 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
19128 is an aliased view, even when rewritten as a reference to the target
19129 object in an assignment.
19130 (Get_Subprogram_Entity): New function
19131 (Known_To_Be_Assigned): New function
19132 (Type_Access_Level): Compute properly the access level of a return
19133 subtype that is an anonymous access type.
19134 (Explain_Limited_Type): Correct use of "\" for continuation messages.
19135 (Is_Transfer): The new extended_return_statement causes a transfer of
19136 control.
19137 (Has_Preelaborable_Initialization): New function
19138 (Has_Null_Exclusion): New function. Given a node N, determine whether it
19139 has a null exclusion depending on its Nkind.
19140 Change Is_Lvalue to May_Be_Lvalue
19141 (May_Be_Lvalue): Extensive additional code to deal with subprogram
19142 arguments (IN parameters are not Lvalues, IN OUT parameters are).
19143 (Safe_To_Capture_Value): Extend functionality so it can be used for
19144 the current value condition case.
19145 (Has_Compatible_Alignment): New function
19146 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
19147 objects to handle the Ada 2005 case, where aliasedness no longer implies
19148 that the object is constrained. In particular, for dereferenced names,
19149 the designated object must be assumed to be unconstrained.
19150 (Kill_Current_Values): Properly deal with the case where we encounter
19151 a loop in the scope chain.
19152 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
19153 a value.

19155
19156 * exp_ch13.adb (Expand_N_Freeze_Entity): Remove the freezing node

19161
19162 * s-osinte-tru64.adb:
19163 Mark Asm statements Volatile to prevent warnings (seems a
19164 reasonable change anyway)
19165 Fixes new warnings
19166
19167 * s-mastop-irix.adb: Add Volatile to Asm statements
19168 Suppresses warning, and seems appropriate in any case
19169
19170 * s-osinte-vms.adb: Add Volatile to Asm statement
19171
19172 * s-vaflop-vms-alpha.adb: Add Volatile to Asm statements

19185 (Is_Entry_Barrier_Function): New flag
19186 (Has_Self_Reference): New flag on aggregates, to indicate that they
19187 contain a reference to the enclosing type, inserted through a default
19188 initialization.
19189 (Next_Rep_Item): Move from Node4 to Node5.
19190 (Entity): Add this field for N_Attribute_Definition_Clause.
19191 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
19192 (N_Return_Object_Declaration): Remove this node kind. We now use
19193 N_Object_Declaration instead.
19194 (Actual_Designated_Subtype): Move to a different place to make room in
19195 N_Extended_Return_Statement.
19196 (Procedure_To_Call): Move to a different place to make room in
19197 N_Extended_Return_Statement.
19198 (Return_Type): Removed this field to make room in return statements
19199 (both kinds).
19200 (Return_Statement_Entity): New field in return statements, in part to
19201 replace Return_Type, and in part to support the fact that return
19202 statements are now pushed on the scope stack during semantic analysis.
19203 (Return_Object_Declarations): New field to support extended return
19204 statements.
19205 (N_Extended_Return_Statement): New node for extended_return_statement
19206 nonterminal.
19207 (N_Return_Object_Declaration): New node for part of
19208 extended_return_statement nonterminal. Needed because all the necessary
19209 fields won't fit in N_Extended_Return_Statement.
19210 Generic_associations now carry the Box_Present flag, to indicate a
19211 default for an actual in a partially parametrized formal package.
19212
19213 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
19214 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
19215 and for the new predefined dispatching policies: EDF_Across_Priorities,
19216 Non_Preemptive_Within_Priorities, and Round_Robin_Within_Priorities.
19217 Introduce new name Stub_Type for implementation defined attribute.
19218 Add pragma Preelaborable_Initialization

20571 Since we are changing the tree format anyway, also get rid of the
20572 junk obsolete Immediate_Errors flag.
20573 (Tree_Read): Change the way of reading Tree_Version_String - now we
20574 read the version string from the tree even if its length is not the
20575 same as the length of the version string computed from Gnatvsn.
20576 (Search_Directory_Present): New Boolean flag for the compiler.
20577 Define Tree_Version_String as a dynamic string.
20578 (Default_Stack_Size): new variable, used to handle switch -d.

20600 (Has_Pragma_Pure): New flag
20601 (No_Return): Present in all entities, set only for procedures
20602 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20603 explicitly declared limited.
20604 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20605 entities. Only used for component marked Is_Tag. If present it stores
20606 the Offset_To_Top function used to provide this value in tagged types
20607 whose ancestor has discriminants.
20608
20609 * exp_ch2.adb: Update status of new Is_Known_Null flag

20626 (__gnat_install_handler): Restore the global vector setup for GCC
20627 versions before 3.4, as the frame based circtuitry is not available
20628 in this case.
20629 (__gnat_set_globals): added a parameter default_stack_size
20630 (__gl_default_stack_size): new variable.
20631
206322006-02-13 Ed Schonberg <schonberg@adacore.com>
20633
20634 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20635 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20636 does not exist in the Ada RM.
20637 (Compatible_Int_Bounds): Determine whether two integer range bounds
20638 are of equal length and have the same start and end values.
20639 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20640 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20641 aggregate when it is part of an object declaration.

20643 constrains discriminants of its parent, add explicitly the discriminant
20644 constraints of the ancestor by retrieving them from the
20645 stored_constraint of the parent.

206472006-02-13 Robert Dewar <dewar@adacore.com>
20648
20649 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20650 attribute Mechanism_Code is applied to renamed subprogram, modify
20651 prefix to point to base subprogram.
20652 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20653
20654 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20655 renamed subprograms so that the front-end must replace the prefix
20656 appropriately.
20657

20659 Gary Dismukes <dismukes@adacore.com>
20660
20661 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20662 availability of RE_Interface_Tag.
20663 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20664 (Freeze_Record_Type): Do not generate the tables associated with
20665 timed and conditional dispatching calls through synchronized
20666 interfaces if compiling under No_Dispatching_Calls restriction.
20667 When compiling for Ada 2005, for a nonabstract
20668 type with a null extension, call Make_Controlling_Function_Wrappers
20669 and insert the wrapper function declarations and bodies (the latter
20670 being appended as freeze actions).
20671 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20672 predefined primitives associated with timed and conditional
20673 dispatching calls through synchronized interfaces if we are
20674 compiling under No_Dispatching_Calls.
20675 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20676 service is available before generating a call.
20677 (Make_Controlling_Function_Wrappers): New procedure.
20678 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20679 access-to-limited-interfaces because they can be used to reference
20680 tasks that implement such limited interface.
20681 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20682 procedure spec and body of the Offset_To_Top function that is generated
20683 when the parent of a type with discriminants has secondary dispatch
20684 tables.
20685 (Init_Secondary_Tags): Handle the case in which the parent of the type
20686 containing secondary dispatch tables has discriminants to generate the
20687 correct arguments to call Set_Offset_To_Top.
20688 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20689
20690 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20691 Add Wide_[Wide_]Expanded_Name.
20692 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20693 the same functionality of Get_Prim_Op_Address but applied to predefined
20694 primitive operations because the pointers to the predefined primitives
20695 are now saved in a separate table.
20696 (Parent_Size): Modified to get access to the separate table of primitive
20697 operations or the parent type.
20698 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20699 functionality of Set_Prim_Op_Address but applied to predefined primitive
20700 operations.
20701 (Set_Signature): New subprogram used to store the signature of a DT.
20702 (Displace): If the Offset_To_Top value is not static then call the
20703 function generated by the expander to get such value; otherwise use
20704 the value stored in the table of interfaces.
20705 (Offset_To_Top): The type of the actual has been changed to Address to
20706 give the correct support to tagged types with discriminants. In this
20707 case this value is stored just immediately after the tag field.
20708 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20709 offset_to_top value is static and hence pass this value to the run-time
20710 to store it in the table of interfaces, or else if this value is dynamic
20711 and then pass to the run-time the address of a function that is
20712 generated by the expander to provide this value for each object of the
20713 type.
20714
20715 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20716 (Default_Prim_Op_Count): New entity
20717 (Get_Predefined_Prim_Op_Address): New entity
20718 (Set_Predefined_Prim_Op_Address): New entity

20723
20724 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20725 Make_Adjust_Call done for a newly-allocated object.
20726
20727 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20728 in a subprogram are wrapped in a cleanup block, indicate that the
20729 subprogram contains an inner block with an exception handler.
20730 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20731 Adjust call is for a newly-allocated object. In that case we must not
20732 assume that the finalization list chain pointers are correct (since they
20733 come from a bit-for-bit copy of the original object's pointers) so if
20734 the attach level would otherwise be zero (no change), we set it to 4
20735 instead to cause the pointers to be reset to null.
20736
20737 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20738 reset chain pointers to null.
20739
207402006-02-13 Ed Schonberg <schonberg@adacore.com>
20741
20742 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20743 string, and the context requires a loop for the assignment (e.g.
20744 because the left-hand side is packed), generate a unique name for the
20745 temporary that holds the string, to prevent spurious name clashes.

20751
20752 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20753 return unconstrained arrays.
20754 Update comments.
20755 (Expand_Call): An indirect call through an access parameter of a
20756 protected operation is not a protected call.
20757 Add circuit to raise CE in Ada 2005 mode following call
20758 to Raise_Exception.
20759 (Register_DT_Entry): Do nothing if
20760 the run-time does not give support to abstract interfaces.
20761 (Freeze_Subprogram): In case of dispatching operations, do not generate
20762 code to register the operation in the dispatch table if the source
20763 is compiled with No_Dispatching_Calls.
20764 (Register_Predefined_DT_Entry): Generate code that calls the new
20765 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20766 Set_Prim_Op_Address.
20767
20768 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20769 on array assignments if the right-hand side is a function call that has
20770 been inlined. Check is performed on the assignment in the block.
20771 (Process_Bounds): If bounds and range are overloaded, apply preference
20772 rule for root operations to disambiguate, and diagnose true ambiguity.
20773 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20774 a tag-indeterminate right-hand side even when Expander_Active is True.
20775 Needed to ensure that dispatching calls to T'Input are allowed and
20776 get the tag of the target class-wide object.
20777
20778 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20779 an inherited primitive operation that already overrides several
20780 abstract interface primitives. For transitivity, the new entity must
20781 also override all the abstract interface primitives covered by the
20782 inherited overriden primitive.
20783 Emit warning if new entity differs from homograph in same scope only in
20784 that one has an access parameter and the other one has a parameter of
20785 a general access type with the same designated type, at the same
20786 position in the signature.
20787 (Make_Inequality_Operator): Use source locations of parameters and
20788 subtype marks from corresponding equality operator when creating the
20789 tree structure for the implicit declaration of "/=". This does not
20790 change anything in behaviour except that the decoration of the
20791 components of the subtree created for "/=" allows ASIS to get the
20792 string images of the corresponding identifiers.
20793 (Analyze_Return_Statement): Remove '!' in warning message.
20794 (Check_Statement_Sequence): Likewise.
20795 (Analyze_Subprogram_Body): For an access parameter whose designated type
20796 is an incomplete type imported through a limited_with clause, use the
20797 type of the corresponding formal in the body.
20798 (Check_Returns): Implicit return in No_Return procedure now raises
20799 Program_Error with a compile time warning, instead of beging illegal.
20800 (Has_Single_Return): Function returning unconstrained type cannot be
20801 inlined if expression in unique return statement is not an identifier.
20802 (Build_Body_To_Inline): It is possible to inline a function call that
20803 returns an unconstrained type if all return statements in the function
20804 return the same local variable. Subsidiary procedure Has_Single_Return
20805 verifies that the body conforms to this restriction.
20806
20807 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20808 same type, and one of them is of an anonymous access type, convert
20809 the other operand to it, so that this is a valid binary operation for
20810 gigi.
20811 (Resolve_Type_Conversion): Handle subtypes of protected types and
20812 task types when accessing to the corresponding record type.
20813 (Resolve_Allocator): Add '\' in 2-line warning message.
20814 Remove '!' in warning message.
20815 (Resolve_Call): Add '\' in 2-line warning message.
20816 (Valid_Conversion): Likewise.
20817 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20818 resulting type may be an access type with an implicit dereference.
20819 Obtain the proper component from the designated type.
20820 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20821 given by an expanded name with prefix Standard, when the operands are
20822 of an anonymous access type.
20823 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20824 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20825 prefix of the expression is not of an incomplete type. Allows full
20826 diagnoses of all semantic errors.
20827 (Resolve_Actuals): If the actual is an allocator whose directly
20828 designated type is a class-wide interface we build an anonymous
20829 access type to use it as the type of the allocator. Later, when
20830 the subprogram call is expanded, if the interface has a secondary
20831 dispatch table the expander will add a type conversion to force
20832 the displacement of the pointer.
20833 (Resolve_Call): If a function that returns an unconstrained type is
20834 marked Inlined_Always and inlined, the call will be inlined and does
20835 not require the creation of a transient scope.
20836 (Check_Direct_Boolean_Op): Removed
20837 (Resolve_Comparison_Op): Remove call to above
20838 (Resolve_Equality_Op): Remove call to above
20839 (Resolve_Logical_Op): Inline above, since this is only call.
20840 (Valid_Conversion): Handle properly conversions between arrays of
20841 convertible anonymous access types.
20842
20843 PR ada/25885
20844 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20845 the literal in an unchecked conversion, because GCC 4.x needs a static
20846 value for a string bound.

20856 properly.

20861 controlling argument of the dispatching call is an abstract interface
20862 class-wide type then we use it directly.
20863 Check No_Dispatching_Calls restriction.
20864 (Default_Prim_Op_Position): Remove the code that looks for the last
20865 entity in the list of aliased subprograms. This code was wrong in
20866 case of renamings.
20867 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20868 when the source is compiled with the No_Dispatching_Calls restriction.
20869 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20870 if we are compiling with restriction No_Dispatching_Calls.
20871 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20872 subprograms if we are compiling under No_Dispatching_Calls restriction.
20873 (Make_DT): Generate a dispatch table with a single dummy entry if
20874 we are compiling with the No_Dispatching_Calls restriction. In
20875 addition, in this case we don't generate code that calls to the
20876 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20877 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20878 of this subprogram if compiling with the No_Dispatching_Calls
20879 restriction.
20880 (Expand_Type_Conversion): Instead of using the actual parameter,
20881 the argument passed as parameter to the conversion function was

21304 inherited by a user-defined type derived from Address, remove it as
21305 well from the set of candidate interpretations of an overloaded node.
21306 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21307 types.

21310
21311 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21312 redundant use clauses.
21313 In particular, if the scope of two use clauses overlaps, but one is not
21314 entirely included in the other, we should not warn. This can happen
21315 with nested packages.
21316 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21317 reported errors. The bug was reported when the compiler was built
21318 with assertions enabled.
21319 (Find_Type): If the node is a 'Class reference and the prefix is a
21320 synchronized type without a corresponding record, return the type
21321 itself.

213232006-02-13 Javier Miranda <miranda@adacore.com>
21324
21325 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21326 if this is the full-declaration associated with a private declaration
21327 that implement interfaces, then the private type declaration must be
21328 limited.
21329 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21330 as aliased. The use of the 'access attribute is not available for such
21331 object (for this purpose the object should be explicitly marked as
21332 aliased, but being an anonymous type this is not possible).

21347 (Add_One_Interp): Do not add to the list of interpretations aliased
21348 entities corresponding with an abstract interface type that is an
21349 immediate ancestor of a tagged type; otherwise we have a dummy
21350 conflict between this entity and the aliased entity.
21351 (Disambiguate): The predefined equality on universal_access is not
21352 usable if there is a user-defined equality with the proper signature,
21353 declared in the same declarative part as the designated type.
21354 (Find_Unique_Type): The universal_access equality operator defined under
21355 AI-230 does not cover pool specific access types.
21356 (Covers): If one of the types is a generic actual subtype, check whether
21357 it matches the partial view of the other type.

21396
21397 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,

21400 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21401 This prevents scanning leading blanks and sign twice.

21735 to the specification because the frontend generates code that uses this
21736 subprogram.
21737 (Set_Interface_Table): Add missing assertion.
21738 Update documentation describing the run-time structure.
21739 (Displace): New subprogram that displaces the pointer to the object
21740 to reference one of its secondary dispatch tables.
21741 (IW_Membership): Modified to use the new table of interfaces.
21742 (Inherit_TSD): Modified to use the new table of interfaces.
21743 (Register_Interface_Tag): Use the additional formal to fill the
21744 contents of the new table of interfaces.
21745 (Set_Interface_Table): New subprogram that stores in the TSD the
21746 pointer to the table of interfaces.
21747 (Set_Offset_To_Top): Use the additional formal to save copy of

21759
21760 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21761 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21762 record component containing the tag of the secondary dispatch table we
21763 have to use the Offset_To_Top run-time function to get this information;
21764 otherwise if the pointer to the base of the object has been displace
21765 we get a wrong value if we use the 'position attribute.
21766

21772 ensure that the interfaces implemented by the ancestors are placed
21773 at the header of the generated list.
21774 (Expand_Interface_Conversion): Handle the case in which the displacement
21775 associated with the interface conversion is not statically known. In
21776 this case we generate a call to the new run-time subprogram Displace.
21777 (Make_DT): Generate and fill the new table of interfaces.
21778 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21779 Get_Tagged_Kind and Set_Tagged_Kind.
21780 (Tagged_Kind): New function that determines the tagged kind of a type
21781 with respect to limitedness and concurrency and returns a reference to
21782 RE_Tagged_Kind.
21783 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
21784 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21785 primary dispatch table for a type.

21803 RE_TK_Tagged, RE_TK_Task.
21804
21805 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21806 Init_Secondary_Tags_Internal to allow its use with interface types and
21807 also to generate the code for the new additional actual required
21808 by Set_Offset_To_Top.
21809 (Build_Init_Statements): In case of components associated with abstract
21810 interface types there is no need to generate a call to its IP.
21811 (Freeze_Record_Type): Generate Select Specific Data tables only for
21812 concurrent types.
21813 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21814 the bodies and specifications of the predefined primitive operations
21815 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21816 for concurrent types.
21817
21818 * exp_sel.ads, exp_sel.adb: New files.
21819
21820 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21821 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21822 properly protected objects and attach handler in the case of the
21823 restricted profile.
21824 Move embeded package Select_Expansion_Utilities into a separate external
21825 package.

21835
21836 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21837 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21838 about the use and expansion of SAVE_EXPRs in the various possible
21839 renaming handling cases.

21891 Hostparm.Max_Line_Length.
21892
21893 * stylesw.adb (Set_Style_Check_Options, case M): The maximum supported
21894 value for the maximum line length is Max_Line_Length (not
21895 Column_Number'Last).

21937
21938 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21939 and the assignment to a class-wide object, before the assignment we
21940 generate a run-time check to ensure that the tag of the Target is
21941 covered by the tag of the source.

21958 of type conversion.
21959 (Find_Interface): New subprogram that given a tagged type and one of its
21960 component associated with the secondary table of an abstract interface
21961 type, return the entity associated with such abstract interface type.
21962 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21963 base type to create anonymous subtype, because entity may be a locally
21964 declared subtype or generic actual.
21965 (Find_Interface): New subprogram that given a tagged type and one of its
21966 component associated with the secondary table of an abstract interface
21967 type, return the entity associated with such abstract interface type.
21968
21969 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21970 conversion cannot be handled at compile time. In this case we pass this
21971 information to the expander to generate the appropriate code.

21981 interface progenitors.
21982 (Is_Return_By_Reference_Type): Predicate does not apply to limited
21983 interfaces.

22009 legal within a protected type that implements an interface.
22010 (Collect_Interfaces): Do not add to the list the interfaces that
22011 are implemented by the ancestors.
22012 (Derived_Type_Declaration): If the parent of the full-view is an
22013 interface perform a transformation of the tree to ensure that it has
22014 the same parent than the partial-view. This simplifies the job of the
22015 expander in order to generate the correct object layout, and it is
22016 needed because the list of interfaces of the full-view can be given in
22017 any order.
22018 (Process_Full_View): The parent of the full-view does not need to be
22019 a descendant of the parent of the partial view if both parents are
22020 interfaces.
22021 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22022 "limited" the parent must be a limited type.
22023 (Build_Derived_Record_Type): A derived type that is explicitly limited

22032 present in a list.
22033 (Find_Hidden_Interface): New function used to determine whether two
22034 lists of interfaces constitute a set equality. If not, the first
22035 differing interface is returned.
22036 (Process_Full_View): Improve the check for the "no hidden interface"
22037 rule as defined by AI-396.

22045 remove an unnecessary exception handler.
22046 Code reformatting and comment clean ups.
22047
220482005-12-09 Vincent Celier <celier@adacore.com>
22049
22050 * gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U
22051 If GNAT CHECK is called with a project file, but with no
22052 source on the command line, call gnatcheck with all the compilable
22053 sources of the project.
22054 Take into account the new command Check, for gnatcheck. Treat as for
22055 other ASIS tools: take into account project, specific package Check and
22056 Compiler switches.
22057 For ASIS tools, add the switches in package Compiler for
22058 the invocation of the compiler.
22059
22060 * prj-attr.adb: Add package Check and its attributes

22095 * sem_cat.adb (Validate_RCI_Subprogram_Declaration): Revise test for
22096 available user-specified stream attributes on limited parameters to
22097 also test the type directly rather than only its underlying type (for
22098 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22099 attributes are visible at the point of the subprogram declaration.
22100 For Ada 2005, the error message is modified to indicate that the
22101 type's stream attributes must be visible (again, only for -gnat05).

22122 Remove_Conversions, to remove ambiguities caused by abstract operations
22123 on numeric types when operands are universal.

22585 (gnat_stabilize_reference): Now a simple wrapper around
22586 maybe_stabilize, for common uses without restriction on lvalues and
22587 without need to check for the success indication.
22588 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22589 pass false instead of 0 as the FORCE argument which is a bool.
22590 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22591 attached to a renaming pointer has been properly stabilized, as no such
22592 object is attached otherwise.
22593 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22594 function uses the "target pointer" return mechanism.
22595 Reinstate conversion of the actual to the type of the formal
22596 parameter before any other specific treatment based on the passing
22597 mechanism. This turns out to be necessary in order for PLACEHOLDER
22598 substitution to work properly when the latter type is unconstrained.

22627 of a No_Elaboration_Code restriction.

22810 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22811 and related): For a prefix that is an explicit dereference of an
22812 access to unconstrained packed array type, annotate the dereference
22813 with an actual subtype so GIGI can make a correct size computation.
22814 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22815 'Unrestricted_Access, if the designated type is an interface we
22816 add a type conversion to force the displacement of the pointer
22817 to the secondary dispatch table.

22844 assignment of a value of a tagged type that has been rewritten to a
22845 block statement, it is known by construction that no checks are
22846 necessary for the statements within the block: analyze it with checks
22847 suppressed.
22848 (Expand_N_If_Statement): When killing a dead then-branch in an
22849 if-statement that has elsif_parts, recompute the Current_Value node
22850 for any entity whose value is known from the condition of the first
22851 elsif_part.
22852 (Expand_N_Return_Statement): When returning a mutable record, convert
22853 the return value into its actual subtype in order to help the backend
22854 to return the actual size instead of the maximum. This is another
22855 aftermath of not returning mutable records on the sec-stack anymore.
22856

22858 handling of error msg for suspicious reverse range iteration.

22904 attribute of the N_Free_Statement.
22905 Generate itype for classwide designated object in both cases of
22906 user-specified storage pool: specific and class-wide, not only in the
22907 specific case.
22908 Raise CE when trying to set a not null access type object to null.

23169 full view to construct the full declaration of the derived type.
23170 (Build_Derived_Record_Type): Relax the condition that controls the
23171 execution of the check that verifies that the partial view and

23183 Remove wrong code that avoids the generation of an error message
23184 when the immediate ancestor of the partial view is an interface.
23185 In addition some minor reorganization of the code has been done to
23186 leave it more clear.
23187 (Analyze_Type_Declaration): If type has previous incomplete tagged
23188 partial view, inherit properly its primitive operations.
23189 (Collect_Interfaces): Make public, for analysis of formal

23202 be included in the interface list.
23203 (Access_Definition): If the designated type is an interface that may
23204 contain tasks, create Master_Id for it before analyzing the expression
23205 of the declaration, which may be an allocator.
23206 (Record_Type_Declaration): Set properly the interface kind, for use
23207 in allocators, the creation of master id's for task interfaces, etc.

23215 appear immediately after a subprogram body, when there is no previous
23216 subprogram declaration.
23217 Change name Is_Package to Is_Package_Or_Generic_Package

23230 package associated with a generic instance or formal package, the
23231 private declarations of the parent must be installed (by calling new
23232 procedure Install_Parent_Private_Declarations).
23233 Change name Is_Package to Is_Package_Or_Generic_Package
23234 (Preserve_Full_Attributes): For a synchronized type, the corresponding
23235 record is absent in a generic context, which does not indicate a

23243 Handle properly a renaming_as_body generated for a stream operation
23244 whose default is abstract because the object type itself is abstract.
23245 (Find_Type): If the type is incomplete and appears as the prefix of a
23246 'Class reference, it is tagged, and its list of primitive operations
23247 must be initialized properly.
23248 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23249 private declaration of a parent unit, prior to compiling the private
23250 part of a child unit, find on the scope stack the proper parent entity
23251 on which to link the use clause.

24466 location of the prefix (not the location of the attribute reference) as
24467 the error location.
24468 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24469 a function renaming thereof, is a valid prefix for 'Size (where it is
24470 intepreted as a function call).

24472 prefix of an array attribute can be considered static.

24488 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24489 become local to the whole package.
24490 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24491 the package was already analyzed the new algorithm "replaces" the
24492 real entities by the shadow ones. This is required to ensure that
24493 the order of these entities in the homonym chains does not change;
24494 otherwise we can have undefined references at linking time because
24495 in case of conflicts the external name of the entities will have
24496 a suffix that depends on the order of the entities in the chain.
24497 (Remove_Limited_With_Clause): Complementary code that completes the
24498 new algorithm and replaces the shadow entities by the real ones.
24499 (Install_Limited_Withed_Unit): When unchaining entities before the
24500 installation of the shadow entities, only regular entities of the
24501 public part must be taken into account. This is required to
24502 keep this routine in synch with the work done by Remove_Limited_
24503 With_Clause
24504 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24505 even if unit is analyzed, because the analysis of the unit is
24506 idempotent in any case, and the limited view of the unit may have to
24507 be installed for proper visibility.
24508 (Expand_Limited_With_Clause): Even if the unit in the implicit
24509 with_clause has been analyzed already, a limited view of the package
24510 must be built for the current context, if it does not exist yet.

24516 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24517 defining entity for the instance body, make a new defining identifier
24518 rather than copying the entity of the spec, to prevent accidental
24519 sharing of the entity list.
24520 (Check_Private_View): When exchanging views of private types, build the
24521 list of exchanged views as a stack, to ensure that on exit the exchanges
24522 are undone in the proper order.
24523 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24524 Restore the compilation environment in case of instantiation_error.
24525 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24526 for an anonymous access result.
24527 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24528 (Formal_Entity): Handle properly the case of a formal package that
24529 denotes a generic package renaming.

24540
24541 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24542 underlying type
24543 to check if a type is Constrained in cases related to code generation
24544 (rather than semantic checking) since otherwise we do not generate
24545 similar code for mutable private types depending if their
24546 discriminants are visible or not.
24547 (Check_Abstract_Overriding): Do not complain about failure to override
24548 the primitive operations used in dispatching selects since they will
24549 always be overriden at the freeze point of the type.
24550 (Access_Definition): Separate out handling for resetting the scope
24551 of an anonymous access function result type. Retrieve the scope
24552 of the associated function rather than using Current_Scope, which
24553 does not have a consistent value (depends on whether we're in the
24554 middle of analyzing formal parameters). Add ??? comment about
24555 finding a cleaner way to handle the special cases of scope setting.
24556 (Process_Incomplete_Dependents): A protected operation is never a
24557 dispatching operation (only its wrapper may be).
24558 (Build_Derived_Record_Type): In case of tagged private types that
24559 implement interfaces add derivation of predefined primitive
24560 operations.
24561 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24562 by two parameters that are used in case of derivation from abstract
24563 interface types: No_Predefined_Prims is used to avoid the derivation
24564 of predefined primitives from the interface, and Predefined
24565 Prims_Only is used to complete the derivation predefined primitives
24566 in case of private tagged types implementing interfaces.
24567 Fix typo in comments
24568 (Find_Interface_In_Descendant): Protect the frontend against
24569 wrong code with large circularity chains.
24570 (Is_Private_Overriding): Add support for entities overriding interface
24571 subprograms. The test failed because Entities associated with overriden
24572 interface subprograms are always marked as hidden (and used to build
24573 the secondary dispatch table); in this case the overriden entity is
24574 available through the field abstract_interface_alias (cf. override_
24575 dispatching_operation)
24576 (Access_Definition): Set the scope of the type to Current_Scope for the
24577 case of a function with an anonymous access result type.
24578 (Access_Subprogram_Declaration): Handle creation of the type entity for
24579 an access-to-function type with an anonymous access result.
24580 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24581 in handling for N_Access_Function_Definition.
24582 (Analyze_Subtype_Declaration): Modify the text of error message.
24583 (Derived_Type_Declaration): Modify the text of error message.
24584 (Process_Subtype): Modify the text of error message plus cleanup
24585 of one redundant error message.
24586 (Analyze_Component_Declaration): Code cleanup.
24587 (Analyze_Object_Declaration): Code cleanup.
24588 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24589 attribute in case of access types. Code cleanup.
24590 (Array_Type_Declaration): Code cleanup.
24591 (Process_Discriminants): Create the new null-excluding itype
24592 if required. Code cleanup.
24593 (Process_Subtype): Create the new null-excluding itype if
24594 required. Code cleanup.
24595 (Build_Derived_Record_Type): Code cleanup to avoid calling
24596 twice the subprogram derive_subprograms in case of private
24597 types that implement interfaces. In this particular case the
24598 subprogram Complete_Subprograms_Derivation already does the
24599 job associated with the second call.
24600
24601 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24602 conversion to the full view when generating an operation for a
24603 discriminant whose type may currently be private.

246052005-09-01 Ed Schonberg <schonberg@adacore.com>
24606 Javier Miranda <miranda@adacore.com>
24607
24608 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24609 V (Obj.F), the rewriting does not involve the indexed component, but
24610 only the selected component itself.
24611 Do not apply the transformation if the analyzed node is an actual of a
24612 call to another subprogram.
24613 (Complete_Object_Operation): Retain the entity of the
24614 dispatching operation in the selector of the rewritten node. The
24615 entity will be used in the expansion of dispatching selects.
24616 (Analyze_One_Call): Improve location of the error message associated
24617 with interface.
24618 (Analyze_Selected_Component): No need to resolve prefix when it is a
24619 function call, resolution is done when parent node is resolved, as
24620 usual.
24621 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24622 when attempting to resolve a call transformed from its object notation.
24623 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24624 of the argument list for each interpretation of the operation.
24625 (Try_Object_Operation): The designated type of an access parameter may
24626 be an incomplete type obtained through a limited_with clause, in which
24627 case the primitive operations of the type are retrieved from its full
24628 view.
24629 (Analyze_Call): If this is an indirect call, and the return type of the
24630 access_to_subprogram is incomplete, use its full view if available.
24631
246322005-09-01 Javier Miranda <miranda@adacore.com>
24633 Gary Dismukes <dismukes@adacore.com>
24634
24635 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24636 access types the null-exclusion and access-to-constant attributes must
24637 also match.
24638 (Analyze_Return_Statement): When the result type is an anonymous access
24639 type, apply a conversion of the return expression to the access type
24640 to ensure that appropriate accessibility checks are performed.
24641 (Analyze_Return_Type): For the case of an anonymous access result type,
24642 generate the Itype and set Is_Local_Anonymous_Access on the type.
24643 Add ??? placeholder for check to disallow returning a limited object
24644 in Ada 2005 unless it's an aggregate or a result of a function call.
24645 Change calls from Subtype_Mark to Result_Definition.
24646 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24647 Result_Definition in call to Make_Function_Specification.
24648 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24649 Set_Result_Definition.
24650 (Make_Inequality_Operator): Change formal Subtype_Mark to
24651 Result_Definition in call to Make_Function_Specification.
24652 (Process_Formals): Create the new null-excluding itype if required.
24653 (New_Overloaded_Entity): For an entity overriding an interface primitive
24654 check if the entity also covers other abstract subprograms in the same
24655 scope. This is required to handle the general case, that is, overriding
24656 other interface primitives and overriding abstract subprograms inherited
24657 from some abstract ancestor type.
24658 (New_Overloaded_Entity): For an overriding entity that comes from
24659 source, note the operation that it overrides.
24660 (Check_Conformance, Type_Conformant): Addition of one new formal
24661 to skip controlling formals in the analysis. This is used to
24662 handle overloading of abstract interfaces.
24663 (Base_Types_Match): Add missing case for types imported from
24664 limited-with clauses
24665 (New_Overloaded_Entity): Add barrier to protect the use of
24666 the "alias" attribute.
24667
246682005-09-01 Ed Schonberg <schonberg@adacore.com>
24669
24670 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24671 verify that the procedure and the entry are mode conformant.
24672 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24673 as a different operator, which is often a cut-and-paste error.
24674
246752005-09-01 Javier Miranda <miranda@adacore.com>
24676 Ed Schonberg <schonberg@adacore.com>
24677
24678 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24679 used in controlling parameters exclude null because it is necessary to
24680 read the tag to dispatch, and null has no tag.
24681 (Override_Dispatching_Operation): If the previous operation is inherited
24682 from an interface, it becomes hidden and does not participate in later
24683 name resolution.
24684

24686 Ed Schonberg <schonberg@adacore.com>
24687 Gary Dismukes <dismukes@adacore.com>
24688
24689 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24690 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24691 the expander will generate the corresponding run-time check to evaluate
24692 the expression.
24693 (Resolve_Call): Check for legal type of procedure name or prefix that
24694 appears as a trigger in a triggering alternative.
24695 (Valid_Conversion): If expression is ambiguous and the context involves
24696 an extension of System, remove System.Address interpretations.
24697 (Resolve_Qualified_Expression): Reject the case of a specific-type
24698 qualification applied to a class-wide argument. Enhance comment
24699 to explain checking of Original_Node.
24700 (Resolve_Type_Conversion): The location of the error message was not
24701 general enough to handle the general case and hence it has been removed.
24702 In addition, this patch improves the text of the message.
24703 (Resolve_Type_Conversion): Add missing support for access to interface
24704 types.
24705 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24706 do not expand if the expression is the actual in a call, because proper
24707 expansion will take place when the call itself is expanded.
24708 (Resolve_Allocator): If the context is an unchecked conversion, the
24709 allocator inherits its storage pool, if any, from the target type of
24710 the conversion.

24713 Javier Miranda <miranda@adacore.com>
24714
24715 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24716 inherited interface operation that has an implementation, use the
24717 implementation to avoid spurious ambiguities.
24718 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24719 use the Corresponding_Record_Typ attribute to look for the interface
24720 because it is set by the expander (and hence it is not always
24721 available). For this reason we traverse the list of interfaces
24722 (available in the parent of the concurrent type).
24723 (Interface_Present_In_Ancestor): Handle entities from the limited view
24724
247252005-09-01 Ed Schonberg <schonberg@adacore.com>
24726
24727 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24728 from the list of required components.
24729 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24730 primitive procedure of a limited interface with a controlling first
24731 parameter.
24732 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24733 of an entry.
24734 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24735 capture if it is generated in the second operand of a short-circuit
24736 operation.
24737 Do not capture values for variables with address clauses.
24738 (Is_Object_Reference): Treat a function call as an object reference only
24739 if its type is not Standard_Void_Type.
24740
247412005-09-01 Ed Schonberg <schonberg@adacore.com>

25526 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25527 longer protected objects. They have been replaced by lower-level
25528 suspension objects made up by a mutex and a condition variable (or
25529 their equivalent given a particular OS) plus some internal data to
25530 reflect the state of the suspension object.
25531 (Initialize, Finalize): Add this initialization procedure for
25532 Suspension_Object, which is a controlled type.
25533 (Finalize): Add the finalization procedure for Suspension_Object,
25534 which is a controlled type.
25535
25536 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25537 Ada.Synchronous_Task_Control because there is no longer a need for a

25557 object to False.
25558 (Set_True): Add this procedure that sets the state of the suspension
25559 object to True, releasing the task that was suspended, if any.
25560 (Suspend_Until_True): Add this procedure that blocks the calling task
25561 until the state of the object is True. Program_Error is raised if
25562 another task is already waiting on that suspension object.
25563 (Initialize): Add this procedure for initializing the suspension
25564 object. It initializes the mutex and the condition variable which are
25565 used for synchronization and queuing, and it sets the internal state
25566 to False.
25567 (Finalize): Add this procedure for finalizing the suspension object,
25568 destroying the mutex and the condition variable.

25574 which provides a low-level abstraction (using operating system
25575 primitives) for Ada.Synchronous_Task_Control.
25576 This object is made up by a mutex (for ensuring mutual exclusion), a
25577 condition variable (for queuing threads until the condition is
25578 signaled), a Boolean (State) indicating whether the object is open,
25579 and a Boolean (Waiting) reflecting whether there is a task already

25788 same functionality and it is more clear in case of primitives
25789 associated with abstract interfaces.
25790 (Set_All_Interfaces_DTC_Entity): Removed. As part of the code
25791 clean up, the functionality of this subprogram is now provided
25792 by Set_All_DT_Position.

25805 the object to give access to the interface tag associated with the
25806 secondary dispatch table.
25807 (Expand_Interface_Thunk): New subprogram that generates the code of the
25808 thunk. This is required for compatibility with the C+ ABI.

25832 declaration for a record type that includes self-referential access
25833 components.

25835 declaration, create anonymous access types for each self-referential
25836 access component.
25837 (Analyze_Component_Declaration, Array_Type_Declaration): Indicate that
25838 an access component in this context is a Local_Anonymous_Access, for

25856 derivation if the derived type has an ancestor that is a formal type
25857 declared in the formal part of an enclosing generic.
25858 (Analyze_Object_Declaration): For protected objects, remove the check
25859 that they cannot contain interrupt handlers if not declared at library
25860 level.

25893 Make_Abstract_Interfaces_DT to generate the secondary tables
25894 associated with abstract interfaces.
25895 (Build_Init_Procedure): Modified to initialize all the tags

25904 * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Handle properly an
25905 in-out parameter that is a component in an initialization procedure,
25906 whose constraint might depend on discriminants, and that may be
25907 misaligned because of packing or representation clauses.
25908 (Is_Legal_Copy): New predicate to determine whether a possibly
25909 misaligned in-out actual can actually be passed by copy/return. This
25910 is an error in case the type is by_reference, and a warning if this is
25911 the consequence of a DEC import pragma on the subprogram.
25912 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
25913 interface types
25914 (Expand_Inlined_Call): Mark temporary generated for the return value as
25915 internal, so that no useless scalar normalization is generated for it.

25925 interface, returns the record component containing the tag of the
25926 interface.

25931 is a predefined primitive operation.
25932 (Expand_Subtype_From_Expr): If the expression is a selected component
25933 within an initialization procedure, compute its actual subtype, because
25934 the component may depend on the discriminants of the enclosing record.
25935
25936 * i-cpp.ads, i-cpp.adb:
25937 This package has been left available for compatibility with previous
25938 versions of the frontend. As part of the new layout this is now a
25939 dummy package that uses declarations available at a-tags.ads
25940
25941 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of
25942 "constant access" and "aliased [constant] access" when not compiling

25962 the generic that is created to represent the formal package.
25963 (Analyze_Package_Instantiation): Instantiate body immediately if the

25970 error message condition, null procedures are correctly detected now.
25971 (New_Overloaded_Entity): Bypass trivial overriding indicator check
25972 for subprograms in the context of protected types. Instead, the
25973 indicator is examined in Sem_Ch9 while analysing the subprogram
25974 declaration.
25975 (Check_Overriding_Indicator): Check consistency of overriding indicator
25976 on subprogram stubs as well.
25977 (Analyze_Subprogram_Declaration): Diagnose null procedures declared at
25978 the library level.

25980 the type of the first formal is a concurrent type, replace this type
25981 by the corresponding record type.
25982 (Analyze_Subprogram_Body): Undo the previous work.
25983 (Analyze_Procedure_Call): If the call has the form Object.Op, the
25984 analysis of the prefix ends up analyzing the call itself, after which
25985 we are done.
25986 (Has_Interface_Formals): New subprogram subsidiary to analyze
25987 subprogram_specification that returns true if some non
25988 class-wide interface subprogram is found
25989 (New_Overloaded_Entity): Modified to give support to abstract
25990 interface types
25991 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
25992 access to subprograms must be recursive.
25993 (Is_Unchecked_Conversion): Improve the test that recognizes
25994 instantiations of Unchecked_Conversion, and allows them in bodies that
25995 are to be inlined by the front-end. When the body comes from an
25996 instantiation, a reference to Unchecked_Conversion will be an
25997 Expanded_Name, even though the body has not been analyzed yet.
25998 Replace Is_Overriding and Not_Overriding in subprogram_indication with
25999 Must_Override and Must_Not_Override, to better express intent of AI.
26000 (Analyze_Subprogram_Body): If an overriding indicator is given, check

26014 to give support to abstract interface types
26015
26016 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
26017 in the case where the target type is an anonymous access type of an
26018 object or component (that is, when Is_Local_Anonymous_Access is true).
26019 Prevent the special checks for conversions of access discriminants in
26020 the case where the discriminant belongs to a nonlimited type, since
26021 such discriminants have their accessibility level defined in the same
26022 way as a normal component of an anonymous access type.
26023 (Resolve_Allocator): When an allocator's designated type is a class-wide
26024 type, check that the accessibility level of type given in the

26033 types.
26034 (Valid_Tagged_Conversion): The conversion of a tagged type to an

26037 (Resolve_Actuals): Enable full error reporting on view conversions
26038 between unrelated by_reference array types.
26039 The rule for view conversions of arrays with aliased components is
26040 weakened in Ada 2005.
26041 Call to obsolescent subprogram is now considered to be a violation of
26042 pragma Restrictions (No_Obsolescent_Features).
26043 (Check_Direct_Boolean_Operator): If the boolean operation has been
26044 constant-folded, there is nothing to check.
26045 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26046 check on possible violation of restriction No_Direct_Boolean_Operators
26047 until after expansion of operands, to prevent spurious errors when
26048 operation is constant-folded.

26061 2005 users.
26062 (Analyze_Allocator): For an allocator without an initial value, where
26063 the designated type has a constrained partial view, a discriminant
26064 constraint is illegal.

26082 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
26083 both bound checks, rather than a conjunction.
26084 (Insert_Valid_Check): If the expression is an actual that is an indexed
26085 component of a bit-packed array, force expansion of the packed element
26086 reference, because it is specifically inhibited elsewhere.

26097 (Gnatmake): Remove exception handler that could no longer be exercized
26098 (Compile_Sources.Compile): Use deep copies of arguments, as some of them
26099 may be deallocated by Normalize_Arguments.
26100 (Collect_Arguments): Eliminate empty arguments
26101
26102 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
26103 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.
26104 (Check_Project): Return False when Project is No_Project. Return True
26105 when All_Projects is True.

26146 Has_Specified_Stream_Write (Flag193)
26147 Present in all type and subtype entities. Set for a given view if the
26148 corresponding stream-oriented attribute has been defined by an
26149 attribute definition clause. When such a clause occurs, a TSS is set

26200 (Has_Overriding_Pragma): Remove obsolete implementation of AI-218.
26201 Declare_Inherited_Private_Subprograms): If an explicit operation

26214 * exp_strm.adb (Build_Mutable_Record_Read_Procedure): Reorganize to
26215 first read discriminants into temporary objects, performing checks on
26216 the read values, then possibly performing discriminant checks on the
26217 actual (if it is constrained), and only finally reading the components
26218 into a constrained temporary object.
26219 (Build_Elementary_Input_Call): Adjust the specific circuitry for the
26220 case of reading discriminants of a mutable record type to recognize

26230 Is_Local_Anonymous_Access to check legaliy of attributes in the
26231 context of access components and stand-alone access objects.

26233 treated as available for a limited private type if there is an
26234 attribute_definition_clause that applies to its full view, but not in

26236 (specifically, the sole fact that the full view is non-limited does not
26237 make the attribute available for the partial view).
26238 (Build_Access_Subprogram_Type): Diagnose attempt to apply 'access to a
26239 non-overloaded intrinsic subprogram.
26240 (Check_Stream_Attribute): Reject an attribute reference for an

26262 be rejected, as mandated by AI-195 item 5.
26263
26264 * sem_util.ads, sem_util.adb (Type_Access_Level): Use flag

26282 Is_Overriding, Not_Overriding: Ada2005 flags that indicate the presence
26283 of an overriding indicator in a subprogram or instance.

26326
26327 * exp_aggr.adb (Aggr_Size_OK): An array with no components can always
26328 be expanded in place. The size computation does not require a
26329 subtraction, which would raise an exception on a compiler built with
26330 assertions when the upper bound is Integer'first.
26331 (Flatten): For an array of composite components, take into account the
26332 size of the components to determine whether it is safe to expand the
26333 array into a purely positional representation.

28027 (Expand_Call): Handle case of unaligned objects (in particular those
28028 that come from packed arrays).
28029 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the

28522 and Tok_Synchronized.
28523
28524 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
28525 "dispatching" rather than "primitive" operations, since dispatching
28526 calls are now allowed to abstract formal subprograms (which are not
28527 primitive).
28528 Char_Literal_Value field is now a Uint
28529 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28530 compute the actual subtype of the designated object to impose the proper
28531 index constraints.
28532 (Resolve_Selected_Component): Do not insert an access check if the
28533 prefix is an access type: such a node is expanded into an explicit
28534 dereference, on which the access check is performed anyway. Removes
28535 expensive duplicate checks.
28536 (Resolve_Call): Use new flag Is_Obsolescent and field
28537 Obsolescent_Warning so that pragma Obsolescent works on library
28538 subprograms.
28539 Add support for wide wide character type
28540 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28541 value by a warning message.
28542 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28543 as fixed-point, and one of the operands is non-static and universal, it
28544 can only be an illegal exponentiation operation, in which case there is
28545 no real value to retrieve.
28546
28547 * exp_strm.adb: Add support for wide wide character type
28548 (Build_Elementary_Input_Call): Compute the size of the stream element by

28563
28564 * sem_ch3.adb: Add support for wide wide character type
28565 (Process_Subtype): If constraint is illegal for the type, set Ekind of
28566 now-useless Itype, to prevent cascaded errors on a compiler built
28567 without -gnatp.
28568
28569 * sem_ch8.adb: Add with and use of Sem_Disp.
28570 (Analyze_Subprogram_Renaming): Replace unclean uses of
28571 Corresponding_Spec with Corresponding_Formal_Spec (and delete setting
28572 of Corresponding_Spec to Empty).
28573 (Attribute_Renaming): Replace use of Corresponding_Spec with
28574 Corresponding_ Formal_Spec and simplify condition.
28575 (Use_One_Package): Check that scope of homonym of identifier is defined,
28576 before checking whether it is a wrapper package.
28577 Add support for wide wide character type
28578

28580 (Eval_Arithmetic_Op): Check for compile time known signed integer
28581 overflow in the non-static case.
28582 (Subtypes_Statically_Match): A formal scalar type and its base type do
28583 not statically match.
28584
28585 * sem_util.adb (Collect_Primitive_Operations): Minor change of "/=" to
28586 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28587 subtype).
28588 (Unit_Declaration_Node): Ditto.
28589 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28590 has a packed array type, the prefix has been rewritten into a type

28593
28594 * stand.ads: Add types Wide_Wide_Character and Wide_Wide_String
28595
28596 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28597 Remove ["0A"] from comment, since it can look like a line terminator.
28598 Currently we don't permit this, but this is under discussion by the
28599 ARG, and it is easy enough to use a different example.
28600
28601 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28602 handling UTF-32 encoding for wide wide character.

28610 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28611 notify that constraint error will be raised at run-time
28612 because a null value is assigned to a null-excluding object.
28613 Remove some obsolete declarations and make Char_Code
28614 unsigned.
28615
28616 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28617 corresponding to CE_Null_Not_Allowed, and adjust the output of all the

28621 wrong null-exclusion value by a warning message.
28622 (Enable_Range_Check): Do range check if the prefix is an
28623 explicit dereference whose designated object is an unconstrained array.
28624 Current algorithm for removing duplicate checks is over-eager in this
28625 case.
28626
28627 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
28628 null-exclusion value by a warning message
28629

28640
28641 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28642 defined for subprogram renaming declarations. When set, the field
28643 indicates the defining entity of a corresponding formal subprogram
28644 when the renaming corresponds to a formal subprogram association in an
28645 instantiation.
28646 (Set_Corresponding_Formal_Spec): New procedure to return
28647 Corresponding_Formal_Spec field.
28648 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration

28656 associated with a tagged primitive subprogram.
28657 (Expand_Dispatching_Call): Add support for a controlling actual that is
28658 directly a value of type Ada.Tag rather than a tagged object.
28659
28660 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28661 describing the new layout.
28662 (Dispatch_Table): The expander computes the actual array size, allocates
28663 the Dispatch_Table record accordingly, and generates code that displaces
28664 the base of the record after the Typeinfo_Ptr component. The access to
28665 these components is done by means of local functions.
28666 (Offset_To_Top): New function.
28667 (Typeinfo_Ptr): New function.
28668 (Get_TSD): Modified to access the new position of the TSD.

28679 N_Formal_Subtype_Declaration (which is now a subtype).
28680 (Analyze_Formal_Subprogram): Add handling for
28681 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28682 dispatching, setting the controlling status of the formal parameters
28683 and result, and issuing an error if there is no controlling type for
28684 the formal subprogram.
28685 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28686 which is an unclean use of that field, we set the new field
28687 Corresponding_Formal_Spec to make the formal subprogram available to
28688 processing in Analyze_Subprogram_Declaration.
28689 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28690 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28691 Constrained, so that it is is does not statically match its anonymous
28692 base type.
28693
28694 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28695 abstract formal subprograms in error check for functions returning
28696 abstract types. Set scope of new designator for
28697 a parameterless subprogram, so that it is available when checking the
28698 body for nested subprograms, before full analysis of said body.
28699 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28700 subprogram only if inner one comes from source.
28701 (Analyze_Function_Call): If the call is given in object notation, the
28702 analysis of the name rewrites the node and analyzes it with the proper
28703 argument list. After analyzing the name, if the call has been rewritten
28704 and the result type is set, no further analysis is needed.
28705 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28706 mark in function specification, in a context where the formals are
28707 visible and hide outer homographs.
28708
28709 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28710 as the tagged type for the cases of abstract formal subprograms and
28711 renamings of those. Clean up spec comments.
28712 (Check_Dispatching_Context): Add error message to indicate "abstract
28713 procedure", covering the case of a call to a formal abstract procedure
28714 that has statically tagged operands.
28715 (Check_Dispatching_Call): Check for the case of an actual given by
28716 a tag-indeterminate function call whose type is an ancestor of the
28717 containing call's associated tagged type. This situation can occur
28718 for inherited primitives with function defaults. In this case we
28719 use the tagged type's tag directly as the controlling argument for
28720 the calls.
28721 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28722
28723 * sprint.adb (Sprint_Node_Actual): Split
28724 N_Formal_Subprogram_Declaration into two alternatives for the new

29694 alignment implications.
29695
29696 * utils.c (create_var_decl): Set DECL_COMMON again on targets without
29697 BSS sections.
29698 (process_attributes): Clear DECL_COMMON again when a section attribute
29699 is present.
29700 (finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
29701 SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
29702 (create_field_decl): Special case ADDRESSABLE negative to mean
29703 "no bitfield creation", to be used by make_aligning_type. Don't
29704 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29705 fields claimed addressable still have to be bitfields. Use
29706 value_factor_p instead of a raw binop construction to check for the
29707 position's alignment.

29715
29716 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29717 with an implicit dereference as its prefix, use
29718 Insert_Explicit_Dereference instead of merely rewriting the prefix into
29719 an explicit dereference. This ensures that a reference to the original
29720 prefix is generated, if appropriate.
29721
29722 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29723 dereference is rewritten to an explicit one, generate a reference to
29724 the entity denoted by its prefix using the original prefix node, so
29725 the dereference can be properly recorded as a read of the denoted
29726 access value, if appropriate.
29727
29728 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29729 emitting 'assigned but never read' warning on a variable on the basis
29730 that it has an access type.

29732 subprogram body.

29738 intrinsic
29739
29740 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
29741 leaving call unchanged.
29742 This deals with the case where the pragma Import specified
29743 an external name, to be handled by the back end.
29744
29745 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29746 subprogram which is Imported with convention Intrinsic if an
29747 External_Name argument is specified.

29749 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
29750 with Sem_Ch6.Cannot_Inline.
29751 (Process_Inline): Provide separate warning for inapplicable inline
29752 pragma.
29753 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
29754 treatment is uniform on different targets.

29768 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
29769 for generation of DSA code targeted to the PolyORB PCS.
29770 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
29771 implementation of the partition communication subsystem in ancillary
29772 subprograms.

29803 when an accept statement has a pragma Unreferenced for it.
29804
29805 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29806 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29807 the body, to ensure that warnings are properly emitted for each accept
29808 statement of a given task entry.

29829 Prepend.
29830 (Remove_Next_Debug): Same fix
29831
29832 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29833 maintain back pointers now, though we did not used to, and comments
29834 were out of date).
29835 (Prepend): Remove pragma Inline.
29836 (Remove_Next): Same cleanup
29837
298382004-12-07 Thomas Quinot <quinot@adacore.com>
29839
29840 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29841 used to record an implicit dereference as a read operation on its
29842 prefix when operating under -gnatc. Necessary to avoid spurious
29843 'variable assigned but never read' warnings in that mode.
29844 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29845 is a non-overloaded implicit dereference, call the above subprogram to
29846 ensure proper recording of references.
29847
298482004-12-07 Gary Dismukes <dismukes@adacore.com>
29849

29851 to be resolved later as part of Analyze_Iteration_Scheme's call to
29852 Make_Index.
29853
298542004-12-07 Ed Schonberg <schonberg@adacore.com>

29913 as their usage for sockets is non-portable (using the read and write
29914 functions from the system runtime library is fine on UNIX but won't

29965 address of which may be used to represent "others" and "all others"
29966 choices in exception tables, instead of the current harcoded
29967 (void *)0 and (void *)1.
29968 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29969
29970 * gigi.h (others_decl, all_others_decl): New decls representing the
29971 new Others_Value and All_Others_Value objects.
29972 (struct attrib): Rename "arg" component as "args", since GCC expects a
29973 list of arguments in there.
29974

29976 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29977 addresses.
29978

29980 others_decl and all_others_decl instead of hardcoded dummy addresses
29981 to represent "others" and "all others" choices, which is cleaner and
29982 more flexible with respect to the possible eh pointer encoding policies.
29983

29991 attributes for the current entity and propagate first subtype
29992 attributes to other subtypes.
29993 <E_Procedure>: Attribute arguments are attr->args and not
29994 attr->arg any more.
29995 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29996 argument provided, as this is what GCC expects. Use NULL_TREE instead
29997 of 0 for trees.

30130
30131 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30132 bounds that may contain functions calls, to prevent memory leaks when
30133 the bound contains a call to a function that uses the secondary stack.
30134 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30135 generate temporaries for loop bounds that might contain function calls
30136 that require secondary stack and/or finalization actions.
30137
30138 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30139 selected component and the selector is overloadable (not just a
30140 function) treat as function call, Analyze_Call will disambiguate if
30141 necessary.
30142 (Analyze_Selected_Component): Do not generate an actual subtype for the
30143 selected component if expansion is disabled. The actual subtype is only
30144 needed for constraint checks.
30145 (Analyze_Allocator): If restriction No_Streams is set, then do
30146 not permit objects to be declared of a stream type, or of a
30147 composite type containing a stream.
30148
30149 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30150 No_Streams no longer prohibits with'ing this package.
30151
30152 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30153 discriminants, but the parent base has unknown discriminants, there is
30154 no discriminant constraint to inherit. Such a discrepancy can arise
30155 when the actual for a formal type with unknown discriminants is a
30156 similar private type whose full view has discriminants.
30157 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30158 do not permit objects to be declared of a stream type, or of a
30159 composite type containing a stream.

30163 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30164 protected operations.
30165
30166 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30167 generated name, it complicates decoding in gdb and hinders debugging
30168 of protected operations.
30169 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30170 flag for the protected entry barrier function.
30171 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30172 flag for the protected entry function.

30187 type of the object with the packed array type, set the Analyzed flag
30188 on the object if it is an entity or simple indexed component, to avoid
30189 spurious type errors.

30222 at the end of the command line invocation of the compiler, when
30223 compiling a non-Ada file.
30224 (Build_Global_Archive): When there is no need to rebuild the archive,
30225 set Global_Archive_Exists, so that the archive is passed to the linker

30268 Remove remaining pragma Import for C_Write
30269 Remove C_Read and C_Write from internal implementation unit
30270 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30271 the read and write functions from the system runtime library is fine

30273
30274 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30275 (Check_Selector): Use C_Recv instead of C_Read.
30276 Selectors are the GNAT.Sockets abstraction to perform a select()
30277 call on a set of descriptors. To allow abortion of an ongoing
30278 select operation, some data is written to a dedicated socket that
30279 is always monitored.
30280 Under Windows, the write and read library functions cannot operate
30281 on sockets, so we need to use send and recv instead, which is portable
30282 across all supported platforms.

30397 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30398 designated object of an allocator in place, rather than building it
30399 first on the stack. The previous scheme forces a full copy of the array,
30400 and may be altogether unsusable if the size of the array is too large

30563 corresponding record type if the subtype declaration has no

30581 context of the main unit are established when those other units are
30582 compiled. Otherwise spurious elaboration constraints can generate

30588 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30589 subprogram is called with a parameter that is not an object name. This
30590 situation arises for some cases of illegal code, which is diagnosed
30591 later, and in this case it is wrong to call Is_Aliased, as that might
30592 cause a compiler crash.
30593 (Explain_Limited_Type): Refine previous fix to include
30594 inherited components of derived types, to provide complete information.
30595
30596 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30597 is the prival for a protected object.
30598 It is necessary to mark this entity as a variable, in addition to
30599 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30600 modified to avoid checking the Aliased flag on entities that are not
30601 objects. (Checking that flag for non-objects is erroneous and could
30602 lead to a compiler crash).

30984 packed array types in both little- and big-endian cases. This change
30985 ensures that we no longer count on the unused bits being initialized
30986 for such types (and in particular ensures that equality testing will
30987 only read the relevant bits).
30988 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30989 These changes mean that we no longer need to initialize small packed
30990 arrays.

30992 optimization to an LJM field as to its parent field.

31130
31131 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31132 Common_ATCB record. It contains the dynamic level of protected action
31133 nesting for each task. It is needed for checking whether potentially
31134 blocking operations are called from protected operations.
31135 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31136 Detect_Blocking is active or not in the partition.

31171 insertion of the statement raising Program_Error. The run time
31172 contains the required machinery for handling that.
31173
31174 * sem_util.ads: Change comment associated to procedure
31175 Check_Potentially_Blocking_Operation.
31176 This procedure does not insert a call for raising the exception because
31177 that is currently done by the run time.
31178
31179 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31180
31181 * init.c: Add the global variable __gl_detect_blocking that indicates
31182 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31183 making the pragma available at run time.
31184 (__gnat_set_globals): Pass and update the detect_blocking parameter.

31190
31191 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31192 DB is found in the ali file. Any unit compiled with pragma
31193 Detect_Blocking active forces its effect in the whole partition.
31194
31195 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31196 Detect_Blocking is active and delay is called from a protected
31197 operation.

31203 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
31204 otherwise).

31210 package.
31211
31212 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31213 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31214 Update API in placeholder implemetation of s-parint to reflect changes
31215 in distribution runtime library.
31216
31217 * sem_ch3.adb (Expand_Derived_Record): Rename to
31218 Expand_Record_Extension.
31219
31220 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31221 primitive operations of potentially distributed object types that have
31222 non-controlling anonymous access formals.
31223
31224 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31225 subprogram.
31226 New implementation of expansion for remote access-to-subprogram types,
31227 based on the RACW infrastructure.
31228 This version of sem_dist is compatible with PolyORB/DSA as well as
31229 GLADE.
31230
31231 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31232 Asynchrronous that applies to a remote access-to-subprogram type, mark
31233 the underlying RACW type as asynchronous.
31234
31235 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31236 __gnat_using_gnu_linker to 1.
31237
31238 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31239 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31240 GNAT.Perfect_Hash_Generators, and remove the empty
31241 GNAT.Perfect_Hash package.
31242
31243 * atree.adb: Minor reformatting
31244
31245 * exp_ch3.adb (Expand_Derived_Record): Rename to
31246 Expand_Record_Extension.
31247 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31248 a component declaration must remain attached at that point in the
31249 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31250 It is therefore necessary to take a copy of the expression when building
31251 the corresponding assignment statement in the init proc.
31252 As a side effect, in the case of a derived record type, we now see the
31253 original expression, without any rewriting that could have occurred
31254 during expansion of the ancestor type's init proc, and we do not need
31255 to go back to Original_Node.
31256
31257 * exp_ch3.ads (Expand_Derived_Record): Rename to
31258 Expand_Record_Extension.
31259
31260 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31262 type.
31263 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31264 New subprograms. Used to create a proxy tagged object for a remote
31265 subprogram. The proxy object is used as the designated object
31266 for RAS values on the same partition (unless All_Calls_Remote applies).
31267 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31268 System.Partition_Interface.Get_Unique_Remote_Pointer.
31269 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31270 Renamed from Add_RAS_*_Attribute.
31271 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31272 subprograms.
31273 New implementation of expansion for remote access-to-subprogram types,
31274 based on the RACW infrastructure.
31275
31276 * exp_dist.ads (Copy_Specification): Update comment to note that this
31277 function can copy the specification from either a subprogram
31278 specification or an access-to-subprogram type definition.
31279
312802004-09-09 Ed Schonberg <schonberg@gnat.com>
31281
31282 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31283 in an instance, between an explicit subprogram an one inherited from a
31284 type derived from an actual.
31285
31286 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31287 add a polling call if the subprogram is to be inlined by the back-end,
31288 to avoid repeated calls with multiple inlinings.
31289
31290 * checks.adb (Apply_Alignment_Check): If the expression in the address
31291 clause is a call whose name is not a static entity (e.g. a dispatching
31292 call), treat as dynamic.

33536 "variable ... is assigned but never read" since other entities may read
33537 the memory location.

33708 (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent
33709 reduction by the processor, which only uses a 68-bit approximation of

339502004-05-17 Javier Miranda <miranda@gnat.com>
33951
33952 * sem_ch10.adb (Install_Limited_Withed_Unit): Do not install the
33953 limited view of a visible sibling.
33954
339552004-05-14 Robert Dewar <dewar@gnat.com>
33956
33957 * gnat_ugn.texi: Minor change to -gnatS documentation
33958
33959 * sprint.adb: Remove some instances of Assert (False) and for this
33960 purpose replace them by output of a ??? string.
33961
33962 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
33963 Assert (False).
33964
33965 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
33966 flag processing. This was suppressing required dependencies in
33967 No_Run_Time mode and is not needed since the binder does not generate
33968 references for things in libgnat anyway.
33969
33970 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
33971 warning.
33972
339732004-05-14 Thomas Quinot <quinot@act-europe.fr>
33974
33975 * gnat_ugn.texi: Document AIX-specific issue with initialization of
33976 resolver library.
33977
33978 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
33979 action for the case of an actual parameter in an init proc call.
33980
339812004-05-14 Ed Schonberg <schonberg@gnat.com>
33982
33983 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
33984 subtype, check visible entities in base type.
33985
33986 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
33987 actions if the object is a renaming.
33988
33989 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
33990 Check_Formal_Package_Instance, to determine more precisely when the
33991 formal and the actual denote the same entity.
33992
339932004-05-14 Javier Miranda <miranda@gnat.com>
33994
33995 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33996
33997 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33998 corresponding to a private_with must be removed from visibility; it
33999 will be made visible later, just before we analyze the private part of
34000 the package.
34001 (Check_Private_Child_Unit): Allow private_with clauses in public
34002 siblings.
34003 (Install_Siblings): Make visible the private entities of private-withed
34004 siblings.
34005 (Install_Withed_Unit): Do not install the private withed unit if we
34006 are compiling a package declaration and the Private_With_OK flag was
34007 not set by the caller. These declarations will be installed later,
34008 just before we analyze the private part of the package.
34009
34010 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
34011 during the evaluation of the expression that initializes the object,
34012 decorate it with the expected type to avoid cascade errors.
34013 Code cleanup.
34014
34015 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
34016 subprogram we have to install the private_with clauses after its
34017 specification has been analyzed (as documented in AI-262.TXT).
34018
34019 * sem_ch8.adb (Has_Private_With): New function. Determines if the
34020 current compilation unit has a private with on a given entity.
34021 (Find_Direct_Name): Detect the Beaujolais problem described in
34022 AI-262.TXT
34023
34024 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
34025 provides the functionality of the function Is_Ancestor that was
34026 previously available in sem_ch10. It has been renamed to avoid
34027 overloading.
34028
34029 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
34030
340312004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34032
34033 * utils.c (build_vms_descriptor): Use SImode pointers.

34722 subprogram for which no pragma All_Calls_Remote applies, store the
34723 address of the real subprogram in the underlying record type, so local

34747
34748 * sem_ch3.adb (Analyze_Component_Declaration): In case of components
34749 that are anonymous access types the level of accessibility depends on
34750 the enclosing type declaration. In order to have this information, set
34751 the scope of the anonymous access type to the enclosing record type
34752 declaration.
34753 (Array_Type_Declaration): In case of components that are anonymous
34754 access types the level of accessibility depends on the enclosing type
34755 declaration. In order to have this information, set the scope of the
34756 anonymous access type to the enclosing array type declaration.
34757

34764
34765 * sem_util.adb (Type_Access_Level): In case of anonymous access types
34766 that are component_definition or discriminants of a nonlimited type,
34767 the level is the same as that of the enclosing component type.

34814 whether a pragma All_Calls_Remote applies to the subprogram on which
34815 'Access is taken.
34816 No functional change is introduced by this revision; the new parameter
34817 will be used to allow calls to local RCI subprograms to be optimized
34818 to not use the PCS in the case where no pragma All_Calls_Remote applies,
34819 as is already done in the PolyORB implementation of the DSA.
34820

35872 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35873 attribute reference does not denote a subtype, it can be any
35874 expression that has a classwide type, potentially after an implicit
35875 dereference. In particular, the prefix can be a view conversion for
35876 a classwide type (for which Is_Object_Reference holds), but it can
35877 also be a value conversion for an access-to-classwide type. In the
35878 latter case, there is an implicit dereference, and the original node
35879 for the prefix does not verify Is_Object_Reference.

36150 unit.
36151
361522004-03-15 Geert Bosch <bosch@gnat.com>
36153
36154 * a-ngcoty.adb (Modulus): In alternate formula for large real or
36155 imaginary parts, use Double precision throughout.
36156
36157 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36158 we want to be able to compile run-time with -gnata for testing, but
36159 this may also be instantiated in user code that is compiled with -gnata.
36160
361612004-03-15 Olivier Hainque <hainque@act-europe.fr>
36162
36163 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

36167
36168 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

36172 (Register_VMS_Exception): Handle the additional exception data pointer
36173 argument.
36174
36175 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
36176 component, now reflected by an exported accessor.
36177 (is_handled_by): New routine to compute whether the propagated
36178 occurrence matches some handler choice specification. Extracted out of
36179 get_action_description_for, and expanded to take care of the VMS
36180 specifities.
36181 (get_action_description_for): Use is_handled_by instead of an explicit
36182 complex condition to decide if the current choice at hand catches the
36183 propagated occurrence.
36184
36185 * raise.h (Exception_Code): New type for C.
36186
36187 * rtsfind.ads (RE_Id, RE_Unit_Table): Add

36193 characteristics.
36194 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the

36196 routine which will now be able to call the appropriate exception data
36197 accessor instead.
36198
36199 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36200 component of Standard_Exception_Type to be the closest possible to
36201 Exception_Code in System.Standard_Library, that we cannot get at this
36202 point. Expand a ??? comment to notify that this type node should
36203 probably be rewritten later on.
36204
36205 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36206 registration call to include a pointer to the exception object in the
36207 arguments.
36208
36209 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36210 instead of int and explicit bitmasks.
36211
362122004-03-15 Vincent Celier <celier@gnat.com>
36213
36214 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36215 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36216
36217 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36218 longer needed now that it is in the spec of
36219 System.Tasking.Task_Attributes.
36220
36221 * adaint.h, adaint.c: (__gnat_create_output_file): New function

36226
36227 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36228 taken care of in Scan_Make_Arg.
36229 (Scan_Make_Arg): Add the executable suffix only if the argument
36230 following -o, in canonical case, does not end with the executable
36231 suffix. When in verbose mode and executable file name does not end
36232 with executable suffix, output the executable name, in canonical case.
36233
36234 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing

362492004-03-15 Ed Schonberg <schonberg@gnat.com>
36250
36251 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36252 tagged type is inherited, and the parent operation is not frozen yet,
36253 force generation of a freeze node for the inherited operation, so the
36254 corresponding dispatch entry is properly initialized.

36262 bit-aligned field and the right-hand side a string literal, introduce
36263 a temporary before expanding assignment into a loop.
36264
36265 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36266 priority in full, to ensure that any expanded subepxressions of it are
36267 elaborated in the scope of the init_proc.
36268
36269 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36270 after object declaration, skipping over code that may have been
36271 generated for validity checks.
36272
36273 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36274 discriminants, ignore the known discriminants of its full view, if
36275 any, to check legality.
36276
36277 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36278 component if type has unknown discriminants.
36279 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36280 null if type has unknown discriminants.
36281

36312 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36313 Insert_Dereference_Action when rewriting an implicit dereference into
36314 an explicit one, this will be taken care of during expansion of the
36315 explicit dereference.
36316 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36317 of non-packed slices, since the dereference action generated by
36318 expansion of the explicit dereference is needed in any case.
36319 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36320 analyze and resolve the rewritten explicit dereference so it is seen
36321 by the expander.
36322 (Insert_Dereference_Action): This procedure is now called only for the
36323 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36324 dereferences that do not come from source (including explicit
36325 dereferences resulting from rewriting implicit ones), but do not
36326 recursively insert a check for the dereference nodes contained within
36327 the check.
36328 (Insert_Dereference_Action): Clarify and correct comment.

37197 region.
37198
37199 * utils.c (create_field_decl): Augment the head comment about bitfield
37200 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
37201 here, because the former is not accurate enough at this point.
37202 Let finish_record_type decide instead.
37203 Don't make a bitfield if the field is to be addressable.
37204 Always set a size for the field if the record is packed, to ensure the
37205 checks for bitfield creation are triggered.
37206 (finish_record_type): During last pass over the fields, clear
37207 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
37208 not covered by the calls to layout_decl. Adjust DECL_NONADDRESSABLE_P
37209 from DECL_BIT_FIELD.

38036 In case of default initialized aggregate with tasks this parameter is
38037 used to generate a null string (this is just a workaround that must be

41870 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41871 function approach did not work well because of a side effect (the
41872 function call could reallocate the table which was being indexed
41873 using its result). Fixes ada/4851.

42241
42242 * g-socket.ads:
42243 Fix comment of Shutdown_Socket and Close_Socket. These functions

43539
43540 * sem_ch6.adb (Analyze_Subprogram_Body): Kill body in predefined

43542 caused by new Rtsfind changes.
43543
43544 * sem_ch6.adb (Analyze_Subrogram_Body): Do not Check_References if
43545 body is deleted.
43546
43547 * rtsfind.adb (RTE): Make sure we do not try to load unit after

43570
435712001-10-11 Pascal Obry <obry@gnat.com>
43572
43573 * Makefile.in:

43583 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43584 (Set_Source_Table): idem.
43585
43586 * ali-util.ads:
43587 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43588 instead of simple checksum.
43589 (CRC_Match): new function.
43590 (CRC_Error): new constant.
43591
43592 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43593 a CRC now and not a simple checksum. A CRC uses lower-case hex
43594 letters, fixes ambiguity in parsing.
43595
43596 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43597 is what this variable will store.
43598
43599 * bcheck.adb: Change reference to chechsum in comments by CRC.
43600 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43601 rename All_Checksum_Match to All_CRC_Match. Change due to API
43602 renaming since now GNAT does not use a simple checksum but a
43603 CRC using GNAT.CRC32.
43604
43605 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43606 now and not anymore a simple checksum.
43607
43608 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
43609 places.
43610
43611 * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
43612
43613 * scans.adb:
43614 (Restore_Scan_State): rename Checksum to CRC.
43615 (Save_Scan_State): idem.
43616
43617 * scans.ads:
43618 With GNAT.CRC32.
43619 (Checksum): rename to CRC.
43620 (Saved_Scan_State): Save_Checksum field renamed to Save_CRC
43621
43622 * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
43623 GNAT.CRC32). Update copyright notice.
43624
43625 * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
43626 GNAT.CRC32). Update copyright notice.
43627
43628 * scn.adb:
43629 (Accumulate_Checksum): removed.
43630 (Update): new procedure. Add a wide-character into the CRC.
43631
43632 * sinput-l.adb:
43633 (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
43634 (Load_File): fix initialization of S (change Source_Checksum to
43635 Source_CRC)
43636
43637 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
43638 Source_CRC in S initialization.
43639
43640 * sinput.adb (Source_Checksum): renamed to Source_CRC.
43641
43642 * sinput.ads (Source_Checksum): renamed to Source_CRC.
43643 Update comments for the CRC.
43644
43645 * types.adb (Hex): Use lowercase for the letter part.
43646
43647 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43648 for a word. This is currently used only for CRC. In previous version,
43649 the checksum was using a representation with all letter being
43650 upper-case. With the new implementation (using CRC) we do not remove
43651 the 32th bit of the CRC, so we can have an upper-case starting letter
43652 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43653 It is ambigous since the CRC was optional and could be followed by
43654 options like EB, EE. So now this routines uses lower-case letter for
43655 the hexadecimal representation. Strange enough only lower case letters
43656 where checked in Scan_ALI (even if this was not a possible case).
43657
43658 * gnatvsn.ads (Library_Version): changed to 3.15a.
43659
43660 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43661 for the compiler.
43662
43663 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43664 for the compiler.
43665
43666 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43667 Add 2001 to copyright notice
43668 (Accumulate_Checksum): Modify to use System.CRC32.
43669
43670 * ali-util.ads: Redo changes of previous revision to continue to use
43671 the word Checksum. Add 2001 to copyright notice.
43672
43673 * ali.adb: Undo some of previous changes, not needed.
43674 Keep the change for lower case letters in the checksum.
43675
43676 * ali.ads: Undo previous change not needed.
43677
43678 * bcheck.adb: Undo most of previous change, not needed.
43679 But do use Checksums_Match for checksum comparison.
43680
43681 * gnatls.adb: Undo most of previous change, not needed.
43682 But do use Checksums_Match for comparing checksums.
43683
43684 * lib-load.adb: Undo previous change, not needed.
43685
43686 * lib-writ.adb: Undo previous change, not needed.
43687
43688 * lib-writ.ads: Document that checksums use lower case,
43689 not upper case letters.
43690
43691 * scans.adb: Undo previous change, not needed
43692
