2838 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2839 Orig_Prev to Prev in the case where the actual is N_Function_Call or

5034 (Build_Discriminated_Subtype): Do not inherit representation clauses
5035 from parent type if subtype already carries them, because they are

5076 through dispatching, never through static calls).
5077 (Collect_Interps): When only one interpretation has been found, set N's
5078 Entity and Etype to that interpretation, otherwise Entity and Etype may
5079 still refer to an interpretation that was ignored by Add_One_Interp,
5080 in which case would end up with being marked as not overloaded but with

9340 subprogram body that acts as its own spec may not have a non-private
9341 WITH clause on a private sibling.
9342 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
9343 child unit is a renaming, create an implicit with_clause on that
9344 parent, and not on the unit it renames, to prevent visibility errors

9391 of Related_Interface to Related_Type.
9392 (Record_Type_Declaration): Minor reordering of calls to decorate the

9411 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
9412 type from a limited_with_clause, and the full view is available, use it

9441 Gary Dismukes <dismukes@adacore.com>
9443 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
9444 requeue statement is dispatching. Do not emit an error when the name is

9448 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9449 Timed_Entry_Call): Analyze the triggering statement as the first step of
9450 the processing. If this is a dispatching select, postpone the analysis
9451 of all select statements until the Expander transforms the select. This
9452 approach avoids generating duplicate identifiers after the Expander has
9453 replicated some of the select statements. In case the Expander is
9454 disabled, perform regular analysis.
9455 (Check_Triggering_Statement): New routine.
9456 (Analyze_Requeue): Exclude any interpretations that are not entries when
9457 checking overloaded names in a requeue. Also test type conformance for

10025 Minor reformatting.
10026 Add Unreferenced and Warnings (Off) pragmas for cases of
10027 variables modified calls where they are IN OUT or OUT parameters and
10028 the resulting values are not subsequently referenced. In a few cases,
10029 we also remove redundant code found by the new warnings.
10031 * ug_words, vms_data.ads, usage.adb, sem_util.adb, sem_util.ads,

10034 sem_ch11.adb, exp_ch6.adb, einfo.ads, einfo.adb: implement a new
10035 warning controlled by -gnatw.o that warns on cases of out parameter
10036 values being ignored.
10038 2007-10-15 Geert Bosch <bosch@adacore.com>
10040 * adaint.c, socket.c, cal.c: Initial port to arm-mentor-nucleus.
10042 * expect.c: Initial port to arm-mentor-nucleus.
10043 Use kill for __gnat_kill() on VMS.
10045 2007-10-15 Emmanuel Briot <briot@adacore.com>
10047 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
10049 (Xref_Record): Change type for Line, since in the case of a reference to
10050 a predefined entity (as happens for array index types), the line is set
10052 Add support for parsing multiple array index types info, or
10053 multiple inherited interfaces info. This information cannot be stored
10054 in Xref_Entity_Record, which only supports a single instance of Tref_*,
10055 and is therefore stored in the list of references instead. It has a
10056 special treatement later on in tools that use this information.
10058 2007-10-15 Tristan Gingold <gingold@adacore.com>
10060 * debug.adb: Document use of -gnatd.a and -gnatd.I

10066 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
10067 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
10068 care of access to class-wide interface types plus removal of bizarre
10069 conversion of tagged object to access type (reported by Gary
10070 Dismukes). After this patch there is no need to perform any
10071 additional management on these nodes in Expand_Interface_Actuals.
10073 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
10074 that handles use of 'Access and 'Unchecked_Access applied to
10075 actuals covering interface types. Such code is now
10076 centralized in Expand_N_Attribute_Reference.
10078 2007-10-15 Ed Schonberg <schonberg@adacore.com>
10080 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
10081 of tagged types whose ultimate ancestor is a CPP type.

10103 2007-10-15 Bob Duff <duff@adacore.com>
10105 * sem_case.adb, sem_ch13.adb, lib-sort.adb: Replace use of Heap_Sort_A
10106 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
10107 the generic Heap_Sort_G, in order to avoid trampolines.
10109 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
10110 Jose Ruiz <ruiz@adacore.com>
10112 * vx_stack_info.c: New file.
10114 * i-forbla-unimplemented.ads: New file.
10116 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads

10120 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
10121 used by VxWorks targets to have access to task-specific data and be
10122 able to extract the stack boundaries for stack checking.
10123 Use system-vms-ia64.ads on ivms.
10125 * Make-lang.in: Update dependencies.
10127 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
10130 2007-10-15 Vincent Celier <celier@adacore.com>

10144 95 reserved word in its name.
10145 (Process_Project_Level_Array_Attributes): Process new attribute
10146 Runtime_Library_Dir.
10148 * prj-part.adb (Parse_Single_Project): Do not check the name of the
10149 config project against the user project names.

10162 * rtsfind.adb: (Load_RTU): Turn off style checks for Load call
10164 2007-10-15 Gary Dismukes <dismukes@adacore.com>
10166 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
10167 association for an access component, add an association with null as
10168 the expression. Remove testing for array subtypes and the setting in
10169 that case of Ctyp to the array component type, which prevented proper
10170 inclusion of an association for null-initialized arrays. Collapse
10171 condition that tests for array subtypes into just a test of
10172 Is_Partially_Initialized_Type (which already covers arrays anyway).
10174 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
10176 * sem_ch12.adb: Minor code reformatting.
10177 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
10178 find the parent package which may have been hidden by local
10181 2007-10-15 Gary Dismukes <dismukes@adacore.com>
10183 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
10184 flag of derived concurrent types, taking into account the flag setting
10185 on the parent subtype and any new set of discriminants.
10187 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
10189 * sem_ch4.adb: Minor code and comment reformatting.
10190 (Analyze_Allocator): When the designated type of an unconstrained
10191 allocator is a record with unknown discriminants or an array with
10192 unknown range bounds, emit a detailed error message depending on the
10193 compilation mode and whether the designated type is limited.

10255 Document how to do reliable stack checking for the environmental task
10258 * gnat_rm.texi: Rewrite section about No_Implicit_Dynamic_Code.
10259 Document attribute Excluded_Source_Files and indicate that attribute
10260 Locally_Removed_Files is obsolescent.
10262 2007-10-15 Thomas Quinot <quinot@adacore.com>
10264 * g-soccon-vms.ads: Fix value of MSG_WAITALL.
10267 Update documentation to note that OpenVMS 8.3 or later must be used
10268 to generate g-soccon-vms.ads.
10270 * atree.adb: Add ??? comment

10329 (Sloc_to_locus): If mapped location support is enabled, translate
10330 source location into mapped location.
10331 (annotate_with_node): Rename into set_expr_location_from_node.
10332 Call set_expr_location instead of annotate_with_locus.
10333 (Pragma_to_gnu): Adjust for above change.
10334 (Loop_Statement_to_gnu): Likewise.
10335 (call_to_gnu): Likewise.
10336 (Handled_Sequence_Of_Statements_to_gnu): Likewise.
10337 (gnat_to_gnu): Likewise.
10338 (add_stmt_with_node): Likewise.

10344 * sem_ch8.adb (Analyze_Use_Type): Code cleanup.
10345 (Applicable_Use): Emit a warning when a package tries to use itself.
10346 (Use_One_Type): Add variable Is_Known_Used. Emit a warning when a type

10355 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
10357 * a-calend-vms.adb, a-calend.adb:
10358 Add a section on leap seconds control along with two entities used to
10359 enable and disable leap seconds support. The array Leap_Second_Times is
10360 now constant and contains hard time values pre-generated. Remove
10361 all elaboration code used to populate the table of leap seconds.
10364 Add entity Leap_Seconds_Support to the list of global run-time variables
10365 along with a comment on its usage and values.
10366 (Gen_Adainit_Ada): Add code to generate the declaration and import of
10367 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
10368 or one (enabled) depending on the presence of binder switch "-y".

10394 2007-09-26 Olivier Hainque <hainque@adacore.com>
10396 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
10397 #include <utime.h> and #define GCC_RESOURCE_H before
10398 #include <sys/wait.h>.
10399 Add more protections in __gnat_translate_vms.
10401 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before

10421 2007-09-26 Javier Miranda <miranda@adacore.com>
10422 Eric Botcazou <ebotcazou@adacore.com>
10425 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
10426 indirection added to the HT_Link component of the TSD. This is required
10427 to statically allocate the TSD.
10430 Minor reordering of the declarations in the private part. Required to
10431 add a level of indirection to the contents of the TSD component HT_Link.
10432 This is required to statically allocate the TSD.
10434 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
10435 Is_Statically_Allocated set from constant objects.
10436 Do not make exported constants created by the compiler volatile.
10437 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
10440 * trans.c (Identifier_to_gnu): For constants, unshare initializers
10441 before returning them.
10443 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
10444 public part of the package.
10445 (Make_DT): Move HT_Link component out of the TSD record. For this
10446 purpose Make_DT now declares a separate object that stores the
10447 HT_Link value, and initializes the TSD component with the address
10448 of this new object. The addition of this level of indirection is
10449 required to statically allocate the TSD because the TSD cannot
10450 have variable components.
10451 (Expand_Interface_Conversion): Improve the expanded code.
10452 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
10454 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
10455 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
10456 if we are building static dispatch tables then we must not generate
10457 extra code to register the primitive because the dispatch table will
10458 be built at the end of the library package; otherwise we notify that
10459 we cannot build the static dispatch table.
10461 2007-09-26 Robert Dewar <dewar@adacore.com>
10463 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

10481 (Is_Thunk): New attribute applicable to subprograms. True for thunks
10482 associated with interface types.
10483 Extensive comment fixes regarding flags that appear in all entities. The
10484 documentation is now consistent for all such flags (there were a number
10485 of errors in the documentation in this regard).
10487 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
10489 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
10490 of these procedures are passed a function call that already has
10491 build-in-place actuals (testing new flag
10492 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
10493 the case where processing continues.
10494 (Expand_Call): If the call is generated from a thunk body then we
10495 propagate the extra actuals associated with the accessibility
10496 level of the access type actuals.
10498 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
10499 of each extra formal of a protected operation to reference the
10500 corresponding extra formal of the subprogram denoted by the
10501 operation's Protected_Body_Subprogram.
10503 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
10504 N_Function_Call nodes.
10506 2007-09-26 Robert Dewar <dewar@adacore.com>
10508 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
10510 * debug.adb: Add d.s flag.
10512 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10514 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
10515 debug variable so that it won't be initialized when pragma
10516 Initialize_Scalars is in effect.

10520 * freeze.adb (Freeze_Entity): Remove check for preelaborable
10521 initialization of a full view. This is moved to
10522 Analyze_Package_Specification.
10524 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10525 preelaborable initialization of a full view in entity loop.
10526 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10527 its child units are use-visible only if they are visible child units.
10529 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10530 whether an expression can be used within a type declaration that
10531 requires preelaborable init.
10532 (Check_Components): Replace inline code that does partial checking for
10533 preelaborable default expressions with call to
10534 Is_Preelaborable_Expression.
10535 (Has_Preelaborable_Initialization): In the case of a generic actual
10536 subtype, (that is, Is_Generic_Actual is True), return the result of
10537 applying Has_Preelaborable_Initialization to the generic actual's base
10540 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
10542 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
10543 call to Jan_1_Day _Of_Week to optimize its performance.
10544 (Is_Leap): Move the routine to the scope of Week_In_Year.
10545 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10546 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10547 avoids calling Time_Of and Split, thus making it more efficent.
10548 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10550 * g-calend.ads (Week_In_Year): Change comment to reflect new
10553 2007-09-26 Emmanuel Briot <briot@adacore.com>
10555 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10556 Command_Line): New types
10557 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10558 support for defining how switches can be grouped on a command line (as
10559 is the case for -gnatw... for GNAT), and how simple switches can be
10560 used as aliases for more complex switches (-gnatwa is same as
10562 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10563 (Start, Current_*): New subprograms
10564 Added support for parsing an array of strings in addition to the real
10566 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10567 be moved from the body to the private part of the spec.
10568 (*): All subprograms now have an extra parameter with default value to
10569 specify which parser should be used. For backward compatibility, it
10570 defaults to parsing the command line of the application. They were also
10571 modified to properly handle cases where each of the argument does not
10572 start at index 1 (which is always true for Ada.Command_Line, but not
10573 when processing any Argument_List).
10574 (Free): New subprogram
10575 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10576 Argument): New subprograms
10577 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10578 special characters like ':', '=',... are now handled in a single place,
10579 which makes the code more extensible eventually.
10580 (Getopt, Full_Switch): When the switch was returned as part of the
10581 special character '*', make sure it is prepended by the switch character
10582 ('-' in general), so that the application knows whether "foo" or "-foo"
10583 was specified on the command line.
10585 2007-09-26 Florian Villoing <villoing@adacore.com>
10587 * g-dirope.adb (Remove_Dir): In case we are removing directories
10588 recursively, make sure that if an exception is raised during the
10589 processing, the current working directory is reset to its initial
10590 value before propagating the exception.
10592 2007-09-26 Vincent Celier <celier@adacore.com>
10594 * gnatbind.adb: If there are several ALI files specified and there is
10595 a main program to bind, the first ALI is expected to contain the main
10596 subprogram and the names of the binder generated files will be derived
10597 from the first ALI file name.
10598 (Gnatbind): Fix insertion character in invocation of Error_Msg
10600 2007-09-26 Vincent Celier <celier@adacore.com>
10602 * gnatcmd.adb (Check_Files): Do not include sources that have been
10603 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
10605 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10607 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
10608 information about each of its index types, following the type
10609 reference for its component type.
10611 2007-09-26 Vincent Celier <celier@adacore.com>
10613 * make.adb: (Kill): New procedure (__gnat_kill imported)

10635 * prj-attr.adb: New attributes Required_Switches (<language>) in
10636 packages Compiler and Binder.
10638 * prj-nmsc.adb: Major rewrite of the processing of configuration
10639 attributes for gprbuild. No impact on GNAT tools.
10641 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
10642 process configuration attributes: this is done in Prj.Nmsc.Check.
10643 (Recursive_Process): Make a full copy of packages inherited from project
10644 being extended, instead of a shallow copy.
10645 (Process_Project_Tree_Phase_1): New procedure
10646 (Process_Project_Tree_Phase_1): New procedure
10647 (Process): Implementation now uses the two new procedures
10649 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
10650 from the project config, not the tree config that no longer exists.

10665 message to cite use of <> in aggregate component associations rather
10666 than wrongly indicating use of limited aggregates.

10673 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10675 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
10676 ancestor of the derived type, the operations are inherited from the
10677 primary dispatch table of the parent.
10678 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
10679 when the context is an explicit type conversion.
10681 2007-09-26 Ed Schonberg <schonberg@adacore.com>

10976 Thomas Quinot <quinot@adacore.com>
10978 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10979 create an abstract subprogram in the case of 'Input. For 'Output we now
10980 create a real spec/body when the type is abstract, since it can
10981 potentially be called.
10982 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10983 body for 'Output when the type is abstract (only the creation of the
10984 body for 'Input is excluded when the type is abstract).
10985 (Stream_Operation_OK): Add an additional condition in the return
10986 statement, so that False will be returned for TTS_Stream_Input if the
10987 associated tagged type is an abstract extension. Add comments for
10989 (Expand_N_Object_Declaration): For the case of a shared passive
10990 variable, insert init proc call only after the shared variable
10991 procedures have been processed, because the IP call needs to undergo
10992 shared passive variable reference expansion, which requires these
10993 procedures to be available (and elaborated).
10995 2007-09-10 Vincent Celier <celier@adacore.com>
10997 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove
10998 parameter Runtime_Project.
11000 2007-09-10 Ed Schonberg <schonberg@adacore.com>
11002 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
11003 given a box association, the type of the component is discriminated,
11004 and the value of the discriminant is the discriminant of the enclosing
11005 type, retrieve its value from the aggregate itself, where it must have
11008 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
11009 to remove other spurious ambiguities on arithmetic operations involving
11010 literals and addresses, on systems where Address is a visible integer
11011 type, when the operator is called in functional notation.
11012 (Try_Primitive_Operation): Within an instance, a call in prefixed form
11013 is legal when the types match, even if the operation is currently
11016 2007-09-10 Ed Schonberg <schonberg@adacore.com>
11018 * sem_ch12.adb (Build_Local_Package): A formal package with no
11019 associations is legal if all formals have defaults. It is not
11020 equivalent to a formal declared with a box.
11022 2007-09-10 Sergey Rybin <rybin@adacore.com>

11053 which a constant renaming is treated as a normal object declaration.
11054 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
11055 the N_Indexed_Component case.
11056 <N_Indexed_Component>: Fall through to above case.

11062 try again to get an integral mode for it.
11064 2007-09-07 Eric Botcazou <ebotcazou@adacore.com>
11066 Re-apply accidentally reverted change:
11068 2007-02-07 Andreas Krebbel <krebbel1@de.ibm.com>

11071 get_action_description_for): Replace _Unwind_Word with _uleb128_t
11072 and _Unwind_SWord with _sleb128_t.
11074 2007-09-06 Eric Botcazou <ebotcazou@adacore.com>

11078 2007-09-05 Sandra Loosemore <sandra@codesourcery.com>
11080 * trans.c (Compilation_unit_to_gnu): Use set_cfun.

11127 (Mark_Non_Null): If the node for which we just generated an access check
11128 is a reference to an *in* parameter and the reference appears in the

11131 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
11133 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

11136 Update the usage of available flag to reflect the addition of Is_Raised.
11137 (Is_Raised, Set_Is_Raised): Bodies of new routines.
11138 (Write_Entity_Flags): Write the status of flag Is_Raised.
11139 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
11140 spurious ambiguities when integer literals appear in the context of an
11141 address type that is a visible integer type.
11143 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
11144 exceptions never being raised.
11145 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
11148 2007-08-31 Javier Miranda <miranda@adacore.com>
11150 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise
11151 statement when compiling under restriction No_Exceptions_Proparation.
11153 2007-08-31 Ed Schonberg <schonberg@adacore.com>
11155 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
11156 initialization aggregate for the type, generate itype references for
11157 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
11159 2007-08-31 Gary Dismukes <dismukes@adacore.com>
11161 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
11162 library-level package renaming, pass the declaration associated with
11163 the renaming's special debug variable to Qualify_Entity_Names to ensure
11164 that its encoded name is properly qualified.
11166 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
11167 occurring in the list of entities to qualify, and do not attempt to
11168 traverse an entity list in that case. Variables associated with
11169 ` library-level package renamings can now occur in the table.
11171 * exp_dbug.ads: Revise documentation of the encoding for renaming
11174 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
11176 * layout.adb (Layout_Type): Use Underlying_Type to determine whether an
11177 access type points to an unconstrained array.
11179 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
11181 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
11184 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
11185 simple redundant qualifications. The check is performed whenever the
11186 expression is a non-overloaded identifier.
11187 (Resolve_Type_Conversion): Enchance the redundant type conversion check
11188 to include loop parameters.
11189 (Valid_Conversion): Avoid generation of spurious error message.

11193 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
11194 concatenations of string literals into a single literal, in order to
11195 avoid very deep recursion in the front end, which was causing stack
11198 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
11199 string, and the right operand is a string literal (the case of "" &
11200 "..."), optimize by avoiding copying the right operand -- just use the
11201 value of the right operand directly.
11203 * stringt.adb (Store_String_Chars): Optimize by growing the
11204 String_Chars table all at once, rather than appending characters one by
11206 (Write_String_Table_Entry): If the string to be printed is very long,
11207 just print the first few characters, followed by the length. Otherwise,
11208 doing "pn(n)" in the debugger can take an extremely long time.
11210 * sem_prag.adb (Process_Interface_Name): Replace loop doing
11211 Store_String_Char with Store_String_Chars.
11213 2007-08-31 Vincent Celier <celier@adacore.com>

11226 have not been fully analyzed.
11228 2007-08-31 Ed Schonberg <schonberg@adacore.com>
11230 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
11231 flag, for effiency. It is called when analyzing arithmetic operators
11232 and also for actuals in calls that are universal_integers. The flag is
11233 set for the predefined type address, and for any type or subtype
11236 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
11237 Universal_Integer, when the formal is a descendent of address and the
11238 call appears in user code.
11239 (Analyze_Selected_Component): if the prefix is a private extension, the
11240 tag component is visible.
11242 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an
11245 2007-08-31 Robert Dewar <dewar@adacore.com>

11291 when compiling for powerpc64-*-linux.
11292 * system-linux-ppc64.ads: New file.
11294 2007-08-22 Krister Walfridsson <cato@df.lth.se>

11299 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
11301 * misc.c (gnat_type_max_size): Constify.
11303 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11305 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
11306 associated with Standard_Debug_Renaming_Type, to be used as the type of
11307 the special variables whose names provide debugger encodings for
11308 renaming declarations.
11310 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
11311 (Set_Debug_Renaming_Link): Change to set Node25.
11312 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
11313 (Write_Field25_Name): Add case for E_Variable to output
11314 "Debug_Renaming_Link".
11315 (Write_Field23_Name): Correct the output string for "Limited_View".
11317 * exp_dbug.adb: Add with and use of Tbuild.
11318 (Debug_Renaming_Declaration): Replace creation of an enumeration type
11319 and literal with creation of a variable of type
11320 Standard_Debug_Renaming_Type whose name encodes both the renamed object
11321 and the entity of the renaming declaration.
11322 (Qualify_Entity_Name): Add the delayed qualification of the entity name
11323 part of the name of a variable that has a Debug_Renaming_Link.
11325 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
11326 special type to be associated with variables that provide debugger
11327 encodings for renaming declarations.
11329 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11330 Ed Schonberg <schonberg@adacore.com>
11331 Javier Miranda <miranda@adacore.com>
11333 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
11334 ancestor part given by an aggregate to test for an unchecked conversion,
11335 since this can occur in some cases when the ancestor part is a function
11336 call, and we don't want to fall into the recursive call to this
11337 procedure in that case.
11339 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
11340 stream attributes on limited types to account for user-specified
11341 attributes as well as whether Input (resp. Output) becomes available
11342 due to Read (resp. Write) being available for the type. Change Boolean
11343 variable to the more accurate name
11344 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
11345 double-"not" predicate at beginning of return statement to more
11346 understandable form.
11348 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
11349 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
11350 in a block statement and use that as the first statement of the
11351 expanded return rather than incorrectly using the handled sequence as
11352 the first statement.
11354 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
11355 operation, generate an explicit freeze node for it rather than
11356 generating extra formals, to ensure that gigi has the proper order of
11357 elaboration for anonymous subtypes in the signature of the subprograms.
11358 (Build_In_Place_Formal): Move assertion to beginning of loop.
11359 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
11360 applied to a function call (occurs for some cases of 'Input).
11361 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
11362 applied to a function call (occurs for some cases of 'Input).
11364 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
11365 2005, generate an extended return statement enclosing the result object
11368 * freeze.adb (Freeze_Record_Type): Extend the current management of
11369 components that are access type with an allocator as default value: add
11370 missing support to the use of qualified expressions of the
11371 allocator (which also cause freezing of the designated type!)
11372 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
11373 dispatching operation, since extra formals may be needed by calls to
11374 build-in-place functions (such as stream 'Input).
11376 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
11377 formals for 'Constrained and accessibility level in the case of a
11378 predefined dispatching operation.
11380 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
11381 point, no need to find the parent node.
11383 2007-08-16 Javier Miranda <miranda@adacore.com>
11385 * exp_attr.adb (Attribute_Priority): Add missing support for entries
11386 and entry barriers.
11388 2007-08-16 Javier Miranda <miranda@adacore.com>
11390 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
11391 is not really required and can introduce regression with the debugger.
11392 The original problem is fixed with the patch written for checks.adb.
11394 2007-08-16 Thomas Quinot <quinot@adacore.com>
11396 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

11406 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
11407 parameter Including_Non_Switch, defaulted to True. When
11408 Including_Non_Switch is False, options that are not switches and
11409 appear as relative path are not converted to absolute paths.
11411 2007-08-16 Nicolas Roche <roche@adacore.com>
11413 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

11424 from the immediate ancestor of Main_Unit_Entity.
11425 (Install_Limited_Withed_Unit): Do not install the limited view of
11426 package P if P is reachable through an ancestor chain from package C
11427 and C also has a with clause for P in its body.

11429 (Has_With_Clause): New routine.
11431 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11433 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
11434 generic for an enclosing instance is a global reference, even though
11435 its scope is the enclosing instance.

11444 Make sure Has_Complex_Representation is inherited by derived type.
11446 2007-08-16 Robert Dewar <dewar@adacore.com>
11448 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
11451 2007-08-16 Ed Schonberg <schonberg@adacore.com>

11458 Bob Duff <duff@adacore.com>
11459 Nicolas Setton <setton@adacore.com>
11461 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
11462 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11463 the statement which is being resolved comes from a predefined library
11464 unit, all non-predefined library interpretations are skipped.
11465 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11466 but the "&" is user defined, give an error, because the folding would
11469 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
11470 the parser has folded a long sequence of concatenations of string
11473 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
11474 and "JMP_BUF" variables as artificial.
11475 (N_String_Literal): Do not use alloca for very long string literals. Use
11476 xmalloc/free instead. Otherwise the stack might overflow.
11478 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
11481 2007-08-16 Vincent Celier <celier@adacore.com>
11483 * vms_conv.adb (Process_Argument): Ensure that project related options
11484 are not put in the -cargs section when using GNAT COMPILE.
11486 2007-08-16 Robert Dewar <dewar@adacore.com>

11518 switch -gnatyS. Enable -gnatyS in GNAT style check mode
11520 2007-08-14 Robert Dewar <dewar@adacore.com>
11521 Ed Schonberg <schonberg@adacore.com>
11523 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
11524 Suppress unmodified in-out parameter warning in some cases
11525 This patch is a also fairly significant change to the way suppressible
11526 checks are handled.
11528 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
11529 needed for access to concurrent record types generated by the expander.
11530 (Generate_Range_Check): When generating a temporary to capture the
11531 value of a conversion that requires a range check, set the type of the
11532 temporary before rewriting the node, so that the type is always
11533 properly placed for back-end use.
11534 (Apply_Float_Conversion_Check): Handle case where the conversion is
11536 (Get_Discriminal): Code reformatting. Climb the scope stack looking
11537 for a protected type in order to examine its discriminants.

11541 Ed Schonberg <schonberg@adacore.com>
11542 Thomas Quinot <quinot@adacore.com>
11544 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
11545 a-stwisu.adb, a-strsup.adb: Fix warnings for range
11546 tests optimized out.
11548 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
11549 (Get_Allocator_Final_List): For the case of an anonymous access type
11550 that has a specified Associated_Final_Chain, do not go up to the
11552 (Expand_N_Type_Conversion): Test for the case of renamings of access
11553 parameters when deciding whether to apply a run-time accessibility
11555 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11556 aggregate code before allocator, and ahead of declaration for
11557 temporary, to prevent access before elaboration when the allocator is
11558 an actual for an access parameter.
11559 (Expand_N_Type_Conversion): On an access type conversion involving an
11560 access parameter, do not apply an accessibility check when the
11561 operand's original node was an attribute other than 'Access. We now
11562 create access conversions for the expansion of 'Unchecked_Access and
11563 'Unrestricted_Access in certain cases and clearly accessibility should
11564 not be checked for those.
11566 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11567 includes a type conversion of a packed component that has been expanded,
11568 recover the original expression for the object, and use this expression
11569 in the post-call assignment statement, so that the assignment is made
11570 to the object and not to a back-end temporary.
11571 (Freeze_Subprogram): In case of primitives of tagged types not defined
11572 at the library level force generation of code to register the primitive
11573 in the dispatch table. In addition some code reorganization has been
11574 done to leave the implementation clear.
11575 (Expand_Call): When expanding an inherited implicit conversion,
11576 preserve the type of the inherited function after the intrinsic
11577 operation has been expanded.
11579 * exp_ch2.ads, exp_ch2.adb
11580 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11581 of an entry formal appearing in an assignment statement does not assign
11583 (Expand_Current_Value): Instead of calling a routine to determine
11584 whether the prefix of an attribute reference should be optimized or
11585 not, prevent the optimization of such prefixes all together.
11587 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11588 component whose prefix is known to be of an access type is an implicit
11589 dereference and does not assign to the prefix.
11591 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11592 Robert Dewar <dewar@adacore.com>
11594 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
11595 itype is visited, make an entry into table to link associated node and
11597 Add comments and correct harmless error in Build_NCT_Hash_Tables
11598 (Array_Aggr_Subtype): Associate each itype created for an index type to
11599 the corresponding range construct, and not to the aggregate itself. to
11600 maintain a one-to-one correspondence between itype and its associated
11601 node, to prevent errors when complex expression is copied.
11602 Fix mishandling of multiple levels of parens
11604 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11605 treatment of limited views uniform for all visible declarations in a
11606 limited_withed package.
11607 (New_Copy_Tree): If hash table is being used and itype is visited,
11608 make an entry into table to link associated node and new itype.
11609 (Resolve_Record_Aggregate): Do not add an others box association for a
11610 discriminated record component that has only discriminants, when there
11611 is a box association for the component itself.
11613 * par-ch4.adb: Fix mishandling of multiple levels of parens
11615 2007-08-14 Robert Dewar <dewar@adacore.com>
11617 * comperr.adb: Fix problem with suppressing warning messages from gigi
11619 * erroutc.ads, erroutc.adb, errout.ads,
11620 errout.adb (Write_Eol): Remove trailing spaces before writing the line
11621 (Write_Eol_Keep_Blanks): New procedure to write a line, including
11622 possible trailing spaces.
11623 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
11624 Fix problem with suppressing warning messages from back end
11625 Improve handling of deleted warnings
11628 Fix problem with suppressing warning messages from back end
11629 Handle setting of Static_Dispatch_Tables flag.
11632 Fix problem with suppressing warning messages from back end
11634 * exp_intr.adb: Improve handling of deleted warnings
11636 2007-08-14 Robert Dewar <dewar@adacore.com>
11638 * debug.adb: Improve -gnatdI to cover all cases of serialization
11639 Add documentation of dZ, d.t
11641 * sprint.ads, sprint.adb: Improve -gnatdI to cover all cases of

11648 Javier Miranda <miranda@adacore.com>
11649 Gary Dismukes <dismukes@adacore.com>
11651 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
11652 to make treatment of limited views uniform for all visible declarations
11653 in a limited_withed package.
11654 Improve warnings for in out parameters
11655 (Set_Related_Interaface/Related_Interface): Allow the use of this
11656 attribute with constants.
11657 (Write_Field26_Name): Handle attribute Related_Interface in constants.
11658 Warn on duplicate pragma Preelaborable_Initialialization
11660 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11661 generation of a freezing node to ensure proper management of null
11662 excluding access types in the backend.
11663 (Create_Extra_Formals): Test base type of the formal when checking for
11664 the need to add an extra accessibility-level formal. Pass the entity E
11665 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11666 originally being done in a couple of cases), to ensure that the
11667 Extra_Formals list gets set on the entity E when the first entity is
11669 (Conforming_Types): Add missing calls to Base_Type to the code that
11670 handles anonymous access types. This is required to handle the
11671 general case because Process_Formals builds internal subtype entities
11672 to handle null-excluding access types.
11673 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11674 functions that need it, even when not marked Requires_Overriding.
11675 Improve warnings for in out parameters
11676 (Analyze_Function_Return): Warn for disallowed null return
11677 Warn on return from procedure with unset out parameter
11678 Ensure consistent use of # in error messages
11679 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11680 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11681 the implicit conversion of the expression done for anonymous access
11682 types. This is required to generate the code of the null excluding
11683 check (if required).
11685 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11686 A formal parameter is never publicly referenceable outside of its body.
11687 (Check_References): For an unreferenced formal parameter in an accept
11688 statement, use the same warning circuitry as for subprogram formal
11690 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11691 Output_Unreferenced_Messages, containing the part of that routine that
11692 is now reused for entry formals as described above.
11693 (Goto_Spec_Entity): New function
11694 (Check_References): Do not give IN OUT warning for dispatching operation
11695 Improve warnings for in out parameters
11696 (Test_Ref): Check that the entity is not undefinite before calling
11697 Scope_Within, in order to avoid infinite loops.
11698 Warn on return from procedure with unset out parameter
11699 Improved warnings for unused variables

11702 Javier Miranda <miranda@adacore.com>
11703 Gary Dismukes <dismukes@adacore.com>
11705 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11706 (Expand_N_Attribute_Reference): Further unify the handling of the
11707 three forms of access attributes, using common code now for all three
11708 cases. Add a test for the case of applying an access attribute to
11709 an explicit dereference when the context is an access-to-interface
11710 type. In that case we need to apply the conversion to the prefix
11711 of the explicit dereference rather than the prefix of the attribute.
11712 (Attribute_Version, UET_Address): Set entity as internal to ensure
11713 proper dg output of implicit importation.
11714 (Expand_Access_To_Type): Removed.
11715 (Expand_N_Attribute_Reference): Merge the code from the three cases
11716 of access attributes, since the processing is largely identical for
11717 these cases. The substantive fix here is to process the case of a
11718 type name prefix (current instance case) before handling the case
11719 of interface prefixes.

11724 Robert Dewar <dewar@adacore.com>
11726 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11727 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11728 type that is an anonymous access to controlled object, establish
11729 an associated finalization chain to avoid corrupting the global
11730 finalization list when a dynamically allocated object designated
11731 by such a component is deallocated.
11732 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11733 functions that need it, even when not marked Requires_Overriding.
11734 (Initialize_Tag): Replace call to has_discriminants by call to
11735 Is_Variable_Size_Record in the circuitry that handles the
11736 initialization of secondary tags.
11737 (Is_Variable_Size_Record): New implementation.
11738 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11739 Suppress_Initialization pragma for a derived type.
11740 (Is_Variable_Size_Record): New subprogram.
11741 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11742 initial version of this routine and also fixes problems causing
11743 incomplete initialization of the table of interfaces.
11744 (Build_Init_Procedure): Improve the generation of code to initialize the
11745 the tag components of secondary dispatch tables.
11746 (Init_Secondary_Tags): New implementation that simplifies the previous
11747 version of this routine.
11748 (Make_DT): Add parameter to indicate when type has been frozen by an
11749 object declaration, for diagnostic purposes.
11750 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11751 diagnose attemps to freeze a subprogram when some untagged type of its
11752 profile is a private type whose full view has not been analyzed yet.
11753 (Freeze_Array_Type): Generate init proc for packed array if either
11754 Initialize or Normalize_Scalars is set.
11755 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11756 constructing the new profile, copy the null_exclusion indicator for each
11757 parameter, to ensure full conformance of the new body with the spec.
11759 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11760 Create wrappers for constructor functions that need it, even when not
11761 marked Requires_Overriding.
11762 (Covers): Handle properly designated types of anonymous access types,
11763 whose non-limited views are themselves incomplete types.
11764 (Add_Entry): Use an entity to store the abstract operation which hides
11766 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11767 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11768 initialization aggregate.
11769 (Function_Interp_May_Be_Hidden): Rename to
11770 Function_Interp_Has_Abstract_Op.
11771 (Has_Compatible_Type): Remove machinery that skips interpretations if
11772 they are labeled as potentially hidden by an abstract operator.
11773 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11774 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11775 (Write_Overloads): Output the abstract operator if present.
11776 (Add_Entry): Before inserting a new entry into the interpretation table
11777 for a node, determine whether the entry will be disabled by an abstract
11779 (Binary_Op_Interp_May_Be_Hidden): New routine.
11780 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11782 (Function_Interp_May_Be_Hidden): New routine.
11783 (Has_Compatible_Type): Do not consider interpretations hidden by
11784 abstract operators when trying to determine whether two types are
11786 (Has_Hidden_Interp): New routine.
11787 (Set_May_Be_Hidden_Interp): New routine.
11788 (Write_Overloads): Write the status of flag May_Be_Hidden.

11791 Javier Miranda <miranda@adacore.com>
11793 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
11794 types declared in the declarative part of a nested package body or in
11795 the proper body of a stub.
11796 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11797 of the same dispatch table slot to renamed primitives.
11798 (Make_Select_Specific_Data_Table): Handle private types.
11799 (Tagged_Kind): Handle private types.
11800 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11801 output of implicit importation and exportation.
11802 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11803 first formal of the thunk is always associated with the controlling
11804 type. In addition perform the following code cleanup: remove formal
11805 Thunk_Alias which is no longer required, cleanup evaluation of the
11806 the controlling type, and update the documentation.
11807 Replace occurrence of Default_Prim_Op_Count by
11808 Max_Predef_Prims. Addition of compile-time check to verify
11809 that the value of Max_Predef_Prims is correct.
11810 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11811 (Make_DT): Add parameter to indicate when type has been frozen by an
11812 object declaration, for diagnostic purposes.
11813 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11814 construction of statically allocated dispatch tables.
11815 (Make_DT): In case of library-level tagged types export the declaration
11816 of the primary tag. Remove generation of tags (now done by Make_Tags).
11817 Additional modifications to handle non-static generation of dispatch
11818 tables. Take care of building tables for asynchronous interface types
11819 (Make_Tags): New subprogram that generates the entities associated with
11820 the primary and secondary tags of Typ and fills the contents of Access_
11821 Disp_Table. In case of library-level tagged types imports the forward
11822 declaration of the primary tag that will be declared later by Make_DT.
11823 (Expand_Interface_Conversion): In case of access types to interfaces
11824 replace an itype declaration by an explicit type declaration to avoid
11825 problems associated with the scope of such itype in transient blocks.
11827 2007-08-14 Robert Dewar <dewar@adacore.com>
11828 Ed Schonberg <schonberg@adacore.com>
11829 Javier Miranda <miranda@adacore.com>
11831 * exp_util.ads, exp_util.adb:
11832 This patch replaces a number of occurrences of explicit tests for N_Null
11833 with calls to Known_Null. This improves tracking of null values, since
11834 Known_Null also catches null constants, and variables currently known to
11835 be null, so we get better tracking.
11836 (Ensure_Defined): create an itype reference only in the scope of the
11838 (Side_Effect_Free): A selected component of an access type that
11839 denotes a component with a rep clause must be treated as not
11840 side-effect free, because if it is part of a linked structure its
11841 value may be affected by a renaming.
11842 (Expand_Subtype_From_Expr): For limited objects initialized with build
11843 in place function calls, do nothing; otherwise we prematurely introduce
11844 an N_Reference node in the expression initializing the object, which
11845 breaks the circuitry that detects and adds the additional arguments to

12316 (Analyze_Compilation_Unit): If unit is a subprogram body that has no
12317 separate declaration, remove the unit name from visibility after
12318 compilation, so that environment is clean for subsequent compilations.

12320 limited_private_with_clause unless the current unit is a body or a
12321 private child unit.

12323 in the same fashion.
12324 (Install_Limited_Withed_Unit): Do not install a limited with clause if
12325 it applies to the declaration of the current package body.
12326 (Remove_Private_With_Clauses): If there is a regular with_clause for
12327 the unit, delete Private_With_Clause from context, to prevent improper
12328 hiding when processing subsequent nested packages and instantiations.

12488 (Set_Item): When the new item is an element of the currently allocated
12489 table passed by reference, save a copy on the stack if we're going

12506 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
12507 derived type with interface progenitors use the analyzed formal as the
12508 parent of the actual, to create renamings for all the inherited
12509 operations in Derive_Subprograms.
12510 (Collect_Previous_Instances): new procedure within of
12511 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12512 unit being loaded, to ensure that the generation of global symbols is
12513 consistent in different compilation modes.
12514 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12515 takes progenitor types into account.
12516 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12517 traversing over the primitives of the formal and actual types to locate
12518 any abstract subprograms of the actual type that correspond to a
12519 nonabstract subprogram of the formal type's ancestor type(s), and issue
12520 an error if such is found.
12521 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12522 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12523 Remove bogus guard around calls to Inherit_Context.
12524 (Reset_Entity): If the entity is the selector of a selected component
12525 that denotes a named number, propagate constant-folding to the generic
12526 template only if the named number is global to the generic unit.
12527 (Set_Instance_Env): Only reset the compilation switches when compiling
12528 a predefined or internal unit.
12530 2007-08-14 Ed Schonberg <schonberg@adacore.com>
12532 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
12533 parameter to determine whether operation applies to the prefix.
12534 (Complete_Object_Operation): If actual has an access type and
12535 controlling formal is not an in_parameter, reject the actual if it is
12536 an access_to_constant type.
12537 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12538 type, the candidate operations are found in the scope of declaration of
12539 the type, because the type has no primitive subprograms.
12540 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12541 a private extension, only examine visible components before trying to
12542 analyze as a prefixed call.
12543 Change Entity_List to Type_To_Use, for better readability.
12544 (Has_Fixed_Op): Use base type when checking whether the type of an
12545 operator has a user-defined multiplication/division
12546 (Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
12547 user-defined operators are available for fixed-point types.

12550 Ed Schonberg <schonberg@adacore.com>
12552 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
12553 formal At_Any_Place indicating, when True, that we want to test for
12554 availability of the stream attribute at any place (as opposed to the
12555 current visibility context only).
12556 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12557 purpose of enforcing E.2.2(8) only if it is not available at any place.
12558 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12559 when checking the legality of an extension aggregate in a preelaborable
12560 package. Treat the literal null as a valid default expression in a
12561 component declaration for a type with preelaborable initialization.
12562 A limited interface is a legal progenitor for the designated type of a
12563 remote access to class-wide type.

12572 setting the Referenced_As_LHS flag for entities that are implicitly
12574 (Find_Type): If the type is an internally generated incomplete type,
12575 mark the full view as referenced, to prevent spurious warnings.
12576 (Find_Selected_Component, Has_Components): Handle properly non-limited
12577 views that are themselves incomplete types.
12578 Handle interfaces visible through limited-with clauses.
12579 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12580 subprogram generic actual for which we have generated a renaming.
12581 Warn when the renaming introduces a homonym of
12582 the renamed entity, and the renamed entity is directly visible.

12588 appear in the subtree to the current allocator if it is not a static
12590 (Resolve_Allocator): Perform cleanup if resolution has determined that
12591 the allocator is not a coextension.
12592 (Resolve): Skip an interpretation hidden by an abstract operator only
12593 when the type of the interpretation matches that of the context.
12594 (Resolve): When looping through all possible interpretations of a node,
12595 do not consider those that are hidden by abstract operators.
12596 (Resolve_Actuals): When verifying that an access to class-wide object
12597 is an actual for a controlling formal, ignore anonymous access to
12598 subprograms whose return type is an access to class_wide type.
12599 (Resolve_Slice): If the prefix of the slice is a selected component
12600 whose type depends on discriminants, build its actual subtype before
12601 applying range checks on the bounds of the slice.
12602 (Valid_Conversion): In an instance or inlined body, compare root types,
12603 to prevent anomalies between private and public views.
12604 (Resolve): Improve error message for ambiguous fixed multiplication
12605 expressions that involve universal_fixed multiplying operations.

12625 elabration statements, register the package with the name server
12626 at the beginning, not at the end, of the elaboration statements so
12627 that they can create remote access to subprogram values that designate
12628 remote subprograms from the package.

13682 (build_call_alloc_dealloc): When releasing a super-aligned object,
13683 retrieve the system's allocator return value from where build_allocator

13711 (Gen_Output_File_Ada, Gen_Output_File_C): Never use __attribute
13712 ((destructor)) for adafinal, even when switch -a is used.
13713 Do not issue pragma Linker_Destructor for adafinal when switch -a is
13715 (Gen_Object_Files_Options): Add formatting of Linker Options, when
13716 Output_Linker_Option_List is set. Suppress this formatting when
13717 Zero_Formatting is set.
13718 Add case for CLI_Target.

13756 an unconstrained array type, and the expression is a slice, use the
13757 bounds of the slice to construct the required constraint checks.
13758 Improve NOT NULL error messages
13759 (Apply_Constraint_Check): If the context is a null-excluding access
13760 type, diagnose properly the literal null.

13776 Arnaud Charlet <charlet@adacore.com>
13778 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13779 applicable to types that have the With_Type flag set. Returns the
13780 non-limited view of the type, if available, otherwise the type itself.
13781 For class-wide types, there is no direct link in the tree, so we have
13782 to retrieve the class-wide type of the non-limited view of the Etype.
13783 New attributes Static_Initialization and Static_Elaboration_Desired.
13784 Remove the pragma Thread_Body, and the associated flag
13785 Is_Thread_Body in entities, and all related code.
13786 (Suppress_Value_Tracking_On_Call): New flag
13787 E_Exception has Esize and Alignment fields

13798 (Original_Access_Type): Remove, not needed.
13799 (Root_Type): Handle properly subtypes of class-wide-types.
13802 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13803 class-wide types visible through limited-with clauses.
13804 (Try_Primitive_Operation): When examining all primitive operations of a
13805 tagged type, do not consider subprograms labeled as hidden unless they
13806 belong to a private generic type with a tagged parent.
13807 (Try_Object_Operation): Extensive rewriting, to handle properly various
13808 overloading cases, when several ancestors may have class-wide operations
13809 that are possible candidates, and when the overloaded functions return
13810 array types and have defaulted parameters so that the call may be
13811 interpreted as an indexing.
13812 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13813 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13814 successive actuals before analyzing the call itself.
13815 (Try_Primitive_Operation): A primitive operation is compatible with the
13816 prefix if the prefix has a synchronized type and the type of the formal
13817 is its corresponding record, as can be the case when the primitive
13818 operation is declared outside of the body of the type.
13819 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13820 perform homonym traversal, looking for class-wide operation matches
13821 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13822 access parameters are now restricted to anonymous access types.
13823 (Mark_Allocator): An allocator with a discriminant association parent is
13825 (Try_One_Prefix_Interpretation): If the type of the object is
13826 incomplete, as can be happen when it is a limited view obtained through
13827 a limited_with_clause, the selected component is not part of a prefixed
13829 (Complete_Object_Operation): Diagnose properly an object that is not
13830 aliased when the corresponding controlling formal is an access
13832 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13833 ambiguous calls in prefixed notation, where two primitives differ only
13834 in that the controlling argument of one is an access parameter.
13836 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13837 whether a function that returns an unconstrained type can be inlined.
13838 (Process_Formals): Diagnose properly the illegal use of an incomplete
13839 type in the profile of an access_to_subprogram declaration.
13840 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13841 operations are attached to the corresponding record.
13842 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13843 When processing a primitive of a concurrent type which implements an
13844 interface change the type of all controlling formals to that of the
13845 corresponding record type.
13846 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13847 to determine the tagged type to which a primitive belongs.
13848 (Check_Conventions): Capture condition to ignore a primitive operation
13849 (which is shared between the loop in Check_Conventions and the one in
13850 Check_Convention) in a new local function Skip_Check.
13851 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13852 confusion with Check_Conventions' own Prim_Op local variable.
13853 (Create_Extra_Formals): Test for a tagged result type rather than a
13854 controlling result when determining whether to add a BIP_Alloc_Form
13855 formal and a BIP_Final_List formal to the function.
13856 (Check_Conformance); For parameters that are anonymous access types,
13857 subtype conformance requires that the not null and the constant
13858 indicators must match
13859 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13860 to retrieve the appropriate type when processing a concurrent type
13861 declared within a generic. Minor comment reformatting. Change invocation
13862 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13864 (Analyze_Subprogram_Body): If the return type of a function is an
13865 anonymous access to the limited view of a class-wide type, and the
13866 non-limited view of the type is available, update the type of the
13867 function so that code can be generated.
13868 (Process_Formals): In case of access-subtype itype whose designated
13869 type is also an itype (situation that happens now with access to
13870 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13871 attribute to avoid backend problems.
13872 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13873 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13874 anonymous types' designated types are same before testing
13875 Subtypes_Statically_Match.
13876 (Create_Extra_Formals): Test for a named access parameter that is a
13877 controlling formal as an additional condition for adding an
13878 accessibility level formal. This can occur in the subp type created for
13879 dispatching calls in Expand_Dispatching_Call, and allows calling
13880 Create_Extra_Formals from that procedure rather than special-casing the
13881 extra formals there.
13882 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13883 when the function has a controlling result.
13884 (Check_Returns): Add much more knowledge of the optimization of local
13885 raise statements to gotos, to retain proper warnings in this case.
13886 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13887 nodes when looking for last statement.
13889 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13890 class-wide types visible through limited with clauses.
13891 (Add_One_Interp): If the operands are anonymous access types, the
13892 predefined operator on universal_access is immediately visibles
13893 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13894 other anonymous access types.
13895 (Disambiguate): Take into account CIL convention.
13896 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13898 2007-06-06 Robert Dewar <dewar@adacore.com>

13903 Fix lower bound of tables.
13906 * nlists.adb: Ditto.
13907 (Prev_Node, Next_Node): Change index type to Int so that it properly

13915 * exp_aggr.ads, exp_aggr.adb:
13916 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13917 in extension aggregates.
13918 (Flatten): Other conditions being met, an aggregate is static if the
13919 low bound given by component associations is different from the low
13920 bound of the base index type.
13921 (Packed_Array_Aggregate_Handled): If the component type is itself a
13922 packed array or record, the front-end must expand into assignments.
13923 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13924 Init_Pr, instead of Ancestor_Is_Expression.
13925 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13926 coextension chain root, either generate a list controller or use the
13927 already existing one.
13928 (Static_Array_Aggregate): New procedure to construct a positional
13929 aggregate that can be handled by the backend, when all bounds and
13930 components are compile-time known constants.
13931 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13932 types covering interface types into assignments.
13933 (Replace_Type): move to Build_Record_Aggr_Code.
13934 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13935 interface type, convert to the definite type of the aggregate itself,
13936 so that needed components are visible.
13937 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13938 components and the context is an extended return statement do not
13939 create a transient block for it, to prevent premature finalization
13940 before the return is executed.
13941 (Gen_Assign): Do not generate a call to deep adjust routine if the
13942 component type is itself an array of controlled (sub)-components
13943 initialized with an inner aggregate.
13944 (Component_Check): New name for Static_Check. This name is now more
13945 appropriate, and documentation is added which was missing.
13946 (Component_Check): Add test for bit aligned component value
13947 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13948 Tagged_Comps, name is more appropriate given added function below.
13949 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13953 Robert Dewar <dewar@adacore.com>
13955 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13956 Terminated: Add unchecked type conversion from System.Address to
13957 System.Tasking.Task_Id when calling the predefined primitive
13959 Disable new Ada 05 accessibility check for JVM.NET targets, which
13960 cannot be implemented in a practical way.
13961 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13962 the sources always references the tag of the actual object. Therefore,
13963 if 'Tag is applied in the sources to class-wide interface objects we
13964 generate code that displaces "this" to reference the base of the object.
13965 (Expand_N_Attribute_Reference, case Size): Return specified size if
13966 known to front end.
13967 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13968 has code that displaces the pointer of the object to manage interface
13969 types. However this code must not be executed when the prefix is a
13970 subprogram. This bug caused the wrong expansion of the internally
13971 generated assignment that fills the dispatch table when the primitive
13972 is a function returning a class-wide interface type.
13973 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13974 Set_Attribute_Name for Name_Unaligned_Valid.

13977 Gary Dismukes <dismukes@adacore.com>
13979 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13980 If the initialization is the equivalent aggregate of the initialization
13981 procedure of the type, do not remove it.
13982 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13983 initialized to null from having their expression reset to empty and

14002 mismatched conventions.
14003 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
14005 (Analyze_Attribute, case 'Access): If the type of the prefix is a
14006 constrained subtype for a nominal unconstrained type, use its base type
14007 to check for conformance with the context.
14008 (Resolve_Attribute): Remove test of the access type being associated
14009 with a return statement from condition for performing accessibility
14010 checks on access attributes, since this case is now captured by
14011 Is_Local_Anonymous_Access.
14012 (Analyze_Access_Attribute): Set Address_Taken on entity
14013 (Analyze_Attribute, case Address): Set Address_Taken on entity
14014 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
14015 validating an access attribute whose prefix is a current instance.
14016 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
14017 applied to dispatching operations, if freezing is required then we set
14018 the attribute Has_Delayed_Freeze in the prefix's entity.
14019 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
14020 current scope if access of local subprogram taken
14021 (Analyze_Access_Attribute): Check legality of self-reference even if the
14022 expression comes from source, as when a single component association in
14023 an aggregate has a box association.
14024 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
14025 the prefix if it is a protected operation and the attribute is
14026 Unrestricted_Access.
14027 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
14028 reference to the base type of the context, to force a constraint check
14029 when the context is an access subtype with an explicit constraint.
14030 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
14031 node is rewritten as an interface conversion. leave unanalyzed after
14032 resolution, to ensure that type checking against the context will take

14039 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
14040 wrapper when the full view of the controlling type of an inherited
14041 function that dispatches on result implements interfaces.
14042 (Expand_N_Object_Declaration): In cases where the type of the
14043 declaration is anonymous access, create finalization list for it.
14044 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
14045 if the object has no explicit initialization, to match description of
14046 functionality of pragam Persistent_BSS.
14047 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
14048 new function to build static aggregates, to replace initialization call
14049 when static initialization is desired.
14050 (Freeze_Type): Generate a list controller for an access type whenever
14051 its designated type has controlled anonymous access discriminants.
14052 (Build_Equivalent_Aggregate): New procedure to compute a static
14053 aggregate to be used as default initialization for composite types,
14054 instead of a generating a call to the initialization procedure for the
14056 (Build_Initialization_Call): When available, replace a call to the
14057 initialization procedure with a copy of the equivalent static aggregate
14059 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
14060 declarations for objects of a class-wide interface type, rather than
14061 just identifiers, to prevent visibility problems.
14062 (Expand_N_Object_Declaration): When expanding the declaration for an
14063 object of a class-wide interface type, preserve the homonym chain of
14064 the original entity before exchanging it with that of the generated
14065 renaming declaration.
14066 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
14067 active, because there is no way to handle the exception.
14068 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
14069 to do a minimum decoration of the Access_Disp_Table list.
14070 (Expand_Record_Controller): Avoid the addition of the controller between
14071 the component containing the tag of a secondary dispatch table and its
14072 adjacent component that stores the offset to the base of the object.
14073 This latter component is only generated when the parent type has
14074 discriminants ---documented in Add_Interface_Tag_Components).
14075 (Apply_Array_Size_Check): Removed, no longer needed.
14076 (Expand_N_Full_Type_Declaration): If the type has anonymous access
14077 components, create a Master_Entity for it only if it contains tasks.
14078 (Build_Init_Procedure): Suppress the tag assignment compiling under
14080 (Freeze_Record_Type): Remove code associated with creation of dispatch
14082 (Init_Secondary_Tags): Update type of actuals when generating calls to
14083 Ada.Tags.Set_Offset_To_Top
14084 (Stream_Operation_OK): Disable use of streams compiling under no
14086 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
14087 if Has_Init_Expression set.
14088 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
14089 Register_Primitive, which provides the same functionality.
14090 (Requires_Init_Proc): Return false in case of interface types.
14091 (Add_Secondary_Tables): Use the new attribute Related_Interface to
14093 (Predefined_Primitive_Freeze): Do not assume that an internal entity
14094 is always associated with a predefined primitive because the internal
14095 entities associated with interface types are not predefined primitives.
14096 Therefore, the call to Is_Internal is replaced by a call to the
14097 function Is_Predefined_Dispatching_Operation.
14098 (Make_Eq_If): When generating the list of comparisons for the
14099 components of a given variant, omit the controller component that is
14100 present if the variant has controlled components.
14102 2007-06-06 Javier Miranda <miranda@adacore.com>
14103 Hristian Kirtchev <kirtchev@adacore.com>
14104 Bob Duff <duff@adacore.com>
14106 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
14107 handle the creation of finalization lists and calls for nested
14108 coextensions when the root of the chains is part of a return statement.
14109 (Inside_A_Return_Statement): New function inside Complete_Coextension_
14111 (Expand_Record_Equality): Skip components that are interface types.
14112 (Displace_Allocator_Pointer): Add missing support for interface subtypes
14113 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
14114 with Rewrite_Coextension. Change the condition for detecting coextension
14116 (Is_Local_Access_Discriminant): Removed.
14117 (Rewrite_Coextension): New routine which rewrites a static coextension
14118 as a temporary and uses its unrestricted access in the construction of
14120 (Complete_Coextension_Finalization): New routine. Generate finalization
14121 attachment calls to all delayed coextensions.
14122 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
14123 the allocator is not a coextension itself and has delayed coextensions.
14124 If the current allocator is controlled, but also a coextension, delay
14125 the generation of the finalization attachment call.
14126 Rename local variable "Node" to "Nod" in order to avoid confusion with
14128 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
14129 limited types that are not inherently limited. Such an allocator is
14130 illegal, but is generated by the expander for a return statement, to
14131 copy the result onto the secondary stack. This is the only case where a
14132 limited object can be copied. Generate code to displace the pointer
14133 to the object if the qualified expression is a class-wide interface
14134 object. Such displacement was missing and hence the copy of the object
14136 (Apply_Accessibility_Check): Handle allocated objects initialized in
14138 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
14139 and Expand_Allocator_Expression. Allocating class-wide interface objects
14140 this routine displaces the pointer to the allocated object to reference
14141 the component referencing the corresponding secondary dispatch table.
14142 Expand_Allocator_Expression): Add missing support to allocate class-wide
14143 interface objects initialized with a qualified expression.
14144 (Get_Allocator_Final_List): Test for an anonymous access type that is a
14145 function result type, and use the finalization list associated with the
14146 function scope in that case (such an anonymous type should not be
14147 treated like an access parameter's type).
14149 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14150 Gary Dismukes <dismukes@adacore.com>
14151 Javier Miranda <miranda@adacore.com>
14153 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
14154 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
14155 required exception handler.
14156 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
14157 properly the case of a function whose return type is a limited
14158 class-wide interface type. Modify the code of the accessibility
14159 check to handle class-wide interface objects. In this case we need to
14160 displace "this" to reference the primary dispatch table to get access
14161 to the TSD of the object (to evaluate its accessibility level).
14162 (Expand_N_Extended_Return_Statement): Test for a tagged result type
14163 rather than a controlling result as one of the conditions for
14164 generating tests of the implicit BIP_Alloc_Form formal. The
14165 initialization assignment is also handled according to whether the
14166 result is tagged instead of controlling.
14167 In the case where the init assignment is inserted in the "then" part of
14168 the allocation conditional, rewrite the target to be a dereference of
14169 the implicit BIP_Object_Access formal.
14170 If the returned value is unconstrained and created on the secondary
14171 stack, mark the enclosing block and function so that the secondary
14172 stack is not reclaimed on return.
14173 Treat returns from functions with controlling results similarly to
14174 returns from functions with unconstrained result subtypes.
14175 If the object returned is unconstrained, and an allocator must be
14176 created for it, analyze the allocator once the block for the extended
14177 return is installed, to ensure that finalizable components
14178 of the expression use the proper finalization list. Guard the call to
14179 Move_Final_List with a check that there is something to finalize.
14180 (Make_Tag_Ctrl_Assignment): Use "old" handling
14181 of controlled type assignment for virtual machines, since new code uses
14182 unsupported features (such as direct access to bytes in memory).
14184 2007-06-06 Gary Dismukes <dismukes@adacore.com>
14185 Ed Schonberg <schonberg@adacore.com>
14187 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
14188 accessibility actual, check for the case of an aliased object that has
14189 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
14190 we fall into processing for the attribute rather than the name of the
14192 (Expand_Inline_Call): If an actual is a literal, and the corresponding
14193 formal has its address taken in the body, create a temporary to capture
14194 value. If the return type is a limited interface, do not treat the
14195 return value as Controlled.
14196 (Is_In_Place_Function): If the return type is a limited interface,
14197 treat as returning in place. The actual returned object may not always
14198 be limited, but the caller has to assume that it is returned in place.
14199 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
14200 context of an allocator, use the correct finalization chain (that is,
14201 the chain belonging to the access type, rather than the chain belonging
14202 to the current scope).
14203 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
14204 result type rather than a controlling result as a precondition for
14205 adding an allocation form actual to a build-in-place call.
14206 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
14207 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
14208 primitive in the dispatch tables. This work is now done by Make_DT when
14209 the type is frozen.
14210 (Register_Predefined_DT_Entry): Removed.
14211 (Add_Return): If end label is not present, use sloc of last statement
14212 for generated return statement in procedure, for better gdb behavior
14214 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
14215 object address nodes to ensure proper processing by routines like
14217 (Expand_Call): Fix generation of validity check for parameter
14218 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
14219 the allocation form parameter if the result subtype is constrained,
14220 except when the function has a controlling result.
14221 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
14222 rather than Is_Controlled and Has_Controlled_Component, since we want to
14223 include class-wide result types in this treatment. Also test for a
14224 controlling result, since that also requires passing a finalization
14226 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
14227 even when the result subtype is constrained, to handle calls involving
14228 controlling results.
14229 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
14230 is now called even when the result subtype is constrained, to handle
14231 calls involving controlling results.
14232 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
14233 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
14234 now performs the test).
14235 (Make_Build_In_Place_Call_In_Object_Declaration):
14236 Add_Alloc_Form_Actual_* is now called even when the result subtype is
14237 constrained, to handle calls involving controlling results.
14238 (Add_Return): Accomodate rewritten pattern from local raise to goto
14239 transformation, so that we still recognize an transfer statement
14240 and do the right thing here in that case.
14241 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
14242 and end of subprogram code.
14243 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14244 support for primitives that are functions (without formals) with a
14245 controlling result.
14246 (Inherited_From_Formal): If the actual subtype has not generic parent
14247 type, it is not an actual for a formal derived type, and there is no
14248 operation to inherit from the formal.
14250 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14251 Thomas Quinot <quinot@adacore.com>
14253 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
14254 inserted cleanup code appropriately for GDB use.
14255 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
14256 exception handler for Deep_Adjust or Deep_Finalize.
14257 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14258 Raise_From_Controlled_Operation is available, use a call to that
14259 subprogram instead of a plain "raise Program_Error" node to raise
14260 Program_Error if an exception is propagated from an Adjust or Finalize
14262 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14263 appears in the optional statement list of a triggering alternative, the
14264 scope actions can be inserted directly there, and not in the list that
14265 includes the asynchronous select itself.
14267 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14268 Robert Dewar <dewar@adacore.com>
14269 Hristian Kirtchev <kirtchev@adacore.com>
14271 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
14272 generated exception handler appropriately when debugging generated code.
14273 Deal properly with No_Exception_Propagation restriction mode.
14274 (Expand_N_Abort_Statement): Add an unchecked type conversion from
14275 System.Address to System.Tasking.Task_Id when processing the result of
14276 the predefined primitive _disp_get_task_id.
14277 (Expand_N_Asynchronous_Select): Clarify comment.
14278 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
14279 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
14280 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
14281 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
14282 privals and for generated call to Complete_Entry_Body, for better gdb
14284 (Copy_Result_Type): Utility to construct a parameter and result profile
14285 for protected functions whose return type is an anonymous access to
14287 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
14289 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
14290 point when the local-raise-to-goto transformation has taken place.
14292 2007-06-06 Javier Miranda <miranda@adacore.com>
14293 Nicolas Setton <setton@adacore.com>
14295 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14296 functionality when the backend is generating code.
14297 Otherwise any serious error
14298 reported by the backend calling the frontend routine Error_Msg
14299 changes the Compilation_Mode to Check_Semantics, disables the
14300 functionality of this routine and causes the generation of
14301 spureous additional errors.
14303 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14304 debugging information now generated by the compiler for fat-pointer
14306 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
14308 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
14310 2007-06-06 Thomas Quinot <quinot@adacore.com>
14312 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
14313 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14314 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14315 For a remote call to a function with a classwide return type, apply an
14316 E.4(18) check to the returned value.
14317 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
14318 stream attributes of the designated type of an RACW, as they are not
14319 dispatching primitive operations.
14321 2007-06-06 Geert Bosch <bosch@adacore.com>
14323 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
14325 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
14327 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
14328 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
14330 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
14332 2007-06-06 Javier Miranda <miranda@adacore.com>
14334 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
14335 attribute compiling package Ada.Tags under No_Run_Time_Mode.
14337 2007-06-06 Javier Miranda <miranda@adacore.com>
14339 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14340 deallocation of class-wide interface objects.
14341 (Expand_Dispatching_Constructor_Call): Take into account that if the
14342 result of the dispatching constructor is an interface type, the
14343 function returns a class-wide interface type; otherwise the returned
14344 object would be actual. The frontend previously accepted returning
14345 interface types because Expand_Interface_Actuals silently performed
14346 the management of the returned type "as if" it were a class-wide
14348 (Expand_Dispatching_Constructor_Call): Replace call to
14349 Make_DT_Access_Action by direct call to Make_Function_Call.
14351 2007-06-06 Robert Dewar <dewar@adacore.com>
14352 Ed Schonberg <schonberg@adacore.com>
14354 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14355 compute masking constant, since we now set Esize properly to the
14357 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14358 to match the alignment.
14359 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
14360 packed arrays of 8 bits or less.
14362 * freeze.adb (Freeze_Entity): When freezing the formals of a
14363 subprogram, freeze the designated type of a parameter of an access type
14364 only if it is an access parameter.
14365 Increase size of C convention enumeration object
14366 (Freeze_Entity, array type case): Make sure Esize value is properly
14367 adjusted for the alignment if it is known.
14368 (Freeze_Entity, array type case): When checking bit packed arrays for
14369 the size being incorrect, check RM_Size, not Esize.
14370 (Freeze_Record_Type): Check for bad discriminated record convention
14371 (In_Exp_Body): Return true if the body is generated for a subprogram
14372 renaming, either an attribute renaming or a renaming as body.
14373 (Check_Itype): If the designated type of an anonymous access component
14374 is a non-protected subprogram type, indicate that it is frozen, to
14375 prevent out-of-scope freeze node at some subsequent call.
14376 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
14377 only if the subprogram is neither imported nor exported, as well as the
14378 NCA descriptor class if the subprogram is exported.
14380 2007-06-06 Ed Schonberg <schonberg@adacore.com>

14383 Gary Dismukes <dismukes@adacore.com>
14385 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
14386 default initialization on an imported object, when there is no
14387 initialization call generated for it.
14388 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
14391 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
14392 Static_Elaboration_Desired.
14393 Remove pragma Thread_Body.
14394 Implement a new pragma No_Body
14395 Removes the Explicit_Overriding pragma
14396 Remove Optional_Overriding pragma
14397 (Prag): Deal with Universal_Aliasing.
14398 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
14399 Pragma_CIL_Constructor): New names.
14401 * sem_cat.adb (Validate_Object_Declaration): An initialization that
14402 uses the equivalent aggregate of a type must be treated as an implicit
14404 (Get_Categorization): Check a unit for pragma Preelaborate only if it
14405 has none of the other categories.
14406 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
14407 to apply Import to an object renaming declaration.
14409 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
14410 from a C++ class should be declared as limited and that it will be
14411 considererd limited.
14412 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
14413 should be declared as limited and that it will be considererd limited.
14414 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
14415 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
14416 (Analyze_Pragma): Deal with Universal_Aliasing.
14417 (Sig_Flags): Likewise.
14418 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
14419 (Overflow_Checks_Unsuppressed): New flag.
14420 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
14421 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
14422 case of JVM or .NET targets, and compiling user code.
14423 Add debugging convenience routine rv
14425 2007-06-06 Robert Dewar <dewar@adacore.com>
14427 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
14428 are interface type.
14429 (Build_Elementary_Input_Call): For floating-point use right type in the
14430 absence of strange size or stream size clauses.
14431 (Build_Elementary_Write_Call): Same fix
14432 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
14433 set to value that does not match base type size.
14435 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14437 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
14438 object of a limited type can be initialized with a call to a function
14439 that returns in place. If the limited type has unknown discriminants,
14440 and the underlying type is a constrained composite type, build an actual
14441 subtype from the function call, as is done for private types.
14442 (Side_Effect_Free): An expression that is the renaming of an object or
14443 whose prefix is the renaming of a object, is not side-effect free
14444 because it may be assigned through the renaming and its value must be
14445 captured in a temporary.
14446 (Has_Controlled_Coextensions): New routine.
14447 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
14448 as is done for other limited types.
14449 (Non_Limited_Designated_Type): new predicate.
14450 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
14452 Remove all handling of with_type clauses.
14454 * par-ch10.adb: Remove all handling of with_type clauses.
14456 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
14457 checksum if the main source could not be parsed.
14458 (Loat_Unit): When processing a child unit, determine properly whether
14459 the parent unit is a renaming when the parent is itself a child unit.
14460 Remove handling of with_type clauses.
14462 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

14467 (Has_Init_Expression): New flag
14468 (Delay_Finalize_Attach): Remove because flag is obsolete.
14469 (Set_Delay_Finalize_Attach): Remove because flag is obsolete.

14473 2007-06-06 Vincent Celier <celier@adacore.com>
14474 Robert Dewar <dewar@adacore.com>
14476 * frontend.adb (Frontend): Return immediately if the main source could
14477 not be parsed, because of preprocessing errors.
14479 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.

16219 renamings of calls to build-in-place functions.
16221 * rtsfind.adb (RTE_Record_Component_Available): New subprogram that

16306 to handle properly the anonymous access case.
16308 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
16309 for all access attributes, because overload resolution should work the
16310 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
16311 causes the error message for the ambiguous "X'Access = Y'Access" and
16312 "X'Unrestricted_Access = Y'Access" and so forth to match.
16313 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
16314 now that anonymous access to protected operations have their own kind.
16315 (Resolve_Attribute): In case of dispatching call check the violation of
16316 restriction No_Dispatching_Calls.
16317 (Check_Array_Type): Check new -gnatyA array index style option

16320 attempt to derive from a synchronized tagged type.
16321 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
16322 type, inherit the class-wide type already created, because it may
16323 already have been used in a self-referential anonymous access component.
16324 (Mentions_T): Recognize self-referential anonymous access components
16325 that use (a subtype of) the class-wide type of the enclosing type.
16326 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
16327 Derived_Type for Prev formal on call to
16328 Check_Anonymous_Access_Components rather than Empty.
16329 (Make_Incomplete_Type_Declaration): Add test for case where the type has
16330 a record extension in deciding whether to create a class-wide type,
16331 rather than just checking Tagged_Present.

16333 to stand-alone object declarations as well as component declarations.
16334 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
16335 prevent accidental overwriting when enclosing package appears in
16336 a limited_with_clause.
16337 (Array_Type_Declaration): If the component type is an anonymous access,
16338 the associated_node for the itype is the type declaration itself.

16340 types with abstract interfaces.
16341 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
16342 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).
16343 (Build_Derived_Record_Type): Add call to Analyze_Interface_Declaration
16344 to complete the decoration of synchronized interface types. Add also
16345 a call to Check_Abstract_Interfaces to verify the ARM rules.
16346 (Derive_Interface_Subprograms): Modified to support concurrent types
16347 with abstract interfaces.
16348 (Analyze_Subtype_Indication): Resolve the range with the given subtype
16349 mark, rather than delaying the full resolution depending on context.

16375 Do not collect arguments if project is externally built.
16376 (Compile_Sources): Do nothing, not even check if the source is up to
16377 date, if its project is externally built.
16378 (Compile): When compiling a predefined source, add -gnatpg
16379 as the second switch, after -c.
16380 (Compile_Sources): Allow compilation of Annex J renames without -a
16381 (Is_In_Object_Directory): Check if the ALI file is in the object
16382 even if there is no project extension.
16383 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
16384 gnatbind if the ALI file effectively exists.
16385 (Initialize): Add the directory where gnatmake is invoked in front of
16386 the path if it is invoked from a bin directory, even without directory
16387 information, so that the correct GNAT tools will be used when spawned
16388 without directory information.

16408 Unchecked_Deallocation only when Renamings_Included is True.
16410 * par.adb: Allow library units Calendar, Machine_Code,
16411 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
16412 when -gnatg is not specified.
16413 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16414 there is no need to generate always a record_definition_node in case
16415 of synchronized interface types.
16416 (SIS_Entry_Active): Initialize global variable to False
16417 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

16439 is non-static even if the component is given by an aggregate with
16441 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
16442 (Convert_Aggr_In_Allocator): If the allocator is for an access
16443 discriminant and the type is controlled. do not place on a finalization
16444 list at this point. The proper list will be determined from the
16446 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
16447 initialize record controller if needed, before the components, to ensure
16448 that they are properly finalized.

16461 accessibility on class-wide allocators if the allocator occurs at the
16462 same scope level as the allocator's type. The check is guaranteed to
16463 succeed in that case, even when the expression originates from a
16464 parameter of the containing subprogram.
16465 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
16466 under No_Dispatching_Calls restriction. During the semantic analysis
16467 we already notified such violation.
16468 (Tagged_Membership): Constant folding. There is no need to check
16469 the tag at run-time if the type of the right operand is non
16470 class-wide abstract.
16471 Replace call to Is_Ancestor by call to Is_Parent
16472 to support concurrent types with interface types.
16473 (Expand_N_Allocator): Add an assertion associated with the generation

16484 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
16485 initialize most the TSD components by means of an aggregate.
16486 Modify the declaration of the object containing the TSD
16487 because we now expand code that has a higher level of abstraction.
16488 The TSD has a discriminant containing the Inheritance Depth Level,
16489 value that is used in the membership test but also to fix the size
16490 of the table of ancestors.
16491 (Expand_Interface_Conversion): Insert function body at the closest place
16492 to the conversion expression, to prevent access-before-elaboration
16493 errors in the backend.

16495 compiling under restriction No_Dispatching_Calls plus code cleanup.
16496 Code reorganization plus removal of calls to Set_Num_Prim_Ops

16519 (Expand_Dispatching_Call): Replace generation of call to the run-time
16520 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
16521 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
16523 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
16524 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
16525 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
16526 Build_Set_Prim_Op_Address.
16527 (Get_Remotely_Callable): Subprogram removed.
16528 (Init_Predefined_Interface_Primitives): Replace generation of call to
16529 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
16532 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
16533 First (Parameter_Associations ()) with the call to First_Actual that
16534 returns an actual parameter expression for both named and positional
16537 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
16538 check violation of restriction No_Dispatching_Calls.
16539 (Check_Controlling_Type): A formal of a tagged incomplete type is a
16540 controlling argument.

16543 First/Next_Component_Or_Discriminant
16544 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
16545 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16546 specify Any_Limited_Interface, and this functionality is already
16547 provided by the function Has_Abstract_Interfaces.
16548 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
16549 support concurrent types implementing interfaces.
16550 (Find_Implemented_Interface): Removed. All the calls to this subprogram
16551 specify kind Any_Limited_Interface, and this functionality is already
16552 provided by the function Has_Abstract_Interfaces.
16553 (Remove_Side_Effects): replace Controlled_Type by
16554 CW_Or_Controlled_Type whenever the issue is related to
16555 using or not the secondary stack.
16557 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
16558 P_Interface_Type_Definition to fulfill the new interface (the formal
16559 Is_Synchronized is no longer required).

16571 anonymous, use finalization list of enclosing dynamic scope.
16572 (Expand_N_Package_Declaration): For a library package declaration
16573 without a corresponding body, generate RACW subprogram bodies in the
16574 spec (just as we do for the task activation call).
16575 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
16576 Is_Abstract_Type. Make sure these are called only when appropriate.
16577 Remove all code for DSP option

16594 Family_Size with 'Cap' set to true.
16595 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16596 a protected version of an operation declared in the private part of
16597 a protected object, because they may be invoked through a callback.
16598 (Set_Privals): If the type of a private component is an anonymous access
16599 type, do not create a new itype for each protected body.
16600 If the body of a protected operation creates
16601 controlled types (including allocators for class-widetypes), the
16602 body of the corresponding protected subprogram must include a

16607 to determine whether operation overrides an inherited primitive.
16608 (Build_Wrapper_Spec): Add code to examine the parents while looking
16609 for a possible overriding candidate.
16610 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16611 hold an actual parameter value since its initialization is separated
16612 from the the declaration. Prevents errors on null-excluding access

16616 Pablo Oliveira <oliveira@adacore.com>
16618 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16619 Do an Unchecked_Conversion to handle the passage from the Underlying
16620 Type to the Base Type when calling Build_To_Any_Call and
16621 Build_From_Any_Call.
16622 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16623 E_Constant, depending upon Variable formal.
16624 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16625 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16626 parameter that requires an extra constrained parameter, declare
16627 temporary for actual as a variable, not a constant.
16628 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16629 the unit being compiled is the one that contains the stub type.
16630 Change primitive operation name for the RACW associated with a RAS
16631 from Call to _Call so it cannot clash with any legal identifier.
16632 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16634 (Append_RACW_Bodies): New subprogram.
16635 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16636 Add_Receiving_Stubs_To_Declarations functions.
16637 When expanding a package body, this list correspond to the
16638 statements in the HSS at the end of the pacakge.
16639 When expanding a package spec, this list correspond to the
16641 (Add_Receiving_Stubs_To_Declarations): Append the function
16642 registering the receiving stubs at the end of the 'Stmts' list.
16643 (RCI_Package_Locator): Pass the new Version generic formal when
16644 instantiating a RCI_Locator package.
16645 (Build_From_Any_Function): To compute the High bound for an
16646 unconstrained array actual, we add the Low bound with the length.
16647 Thus we must convert the low bound and the length to an appropriate
16648 type before doing the sum.
16649 (Build_Subprogram_Receiving_Stubs, PolyORB):
16650 * Retrieve the extra formals parameters at the
16651 end of the parameter stream.
16652 * Use Move_Any_Value to write back out parameters
16653 after executing the request as it is more efficient
16654 than Copy_Any_Value.
16655 * Build the any containing Extra Formals with the
16656 appropriate typecode.
16657 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16658 empty Component_List.
16659 (Build_Actual_Object_Declaration): New subprogram. Build and insert into

16671 function with the first not implicit parent type.
16672 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16673 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16674 typecode from the Etype. Therefore we retrieve the correct typecode
16675 with a call to Get_Any_Type.
16676 (Copy_Specification): Do controlling formal type substitution based on
16677 Is_Controlling_Formal flag, instead of caller-provided object type.
16678 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16679 a RACW primitive operation, we might get a subprogram declaration for an
16680 ancestor of the RACW designated type (not for the designated type
16681 itself), in the case where this operation is inherited. In this case we
16682 have no easy means of determining the original tagged type for which
16683 the primitive was declared, so instead we now rely on
16684 Copy_Specification to use the Is_Controlling_Formal flag to determine
16685 which formals require type substitution.

16691 GNAT.Current_Exception are not allowed if pragma Restrictions
16692 (No_Exception_Propagation) is set and in any case make the associated
16693 handler unsuitable as a target for a local raise statement.
16694 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16695 run-time subprogram CW_Membership by call to Build_CW_Membership.
16696 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16697 by a function call, a temporary must be created before expanding the
16698 Constructor_Call itself, to prevent out-of-order elaboration in the
16699 back-end when stack checking is enabled..
16701 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16703 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the

16830 This is needed as it is necessary to have access to both versions in the
16831 runtime for the form parameter encoding support.
16832 This set of patch add support for the encoding form parameter.
16833 (S2WS): Improve implementation to handle cases where the filename is not
16834 UTF-8 encoded. In this case we default to using the current code page
16835 for the conversion.
16837 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration

16882 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16883 __gnat_adjust_context_for_raise.
16884 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16885 implementation of floating point operations as native x86 targets.
16886 So the FPU should be initialized in the same way using finit. Fix
16887 floating point operations accuracy issues.
16888 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction

16909 types that the type implements. List each of these interfaces when
16910 building the entry for the type.
16911 (Generate_Definition): Initialize component Def and Typ of new entry
16912 in table Xrefs, to avoid to have these components unitialized.

16970 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16971 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16972 there is no need to generate always a record_definition_node in case
16973 of synchronized interface types.
16974 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16975 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16976 illegal in Ada 95, in cases where it is legal. Change the warnings to
16977 errors in other cases. Don't give the error unless the "not null"
16978 parses properly. Correct the source position at which the error occurs.
16979 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to

17058 If the prefix returned by Sdefault is null, get the prefix from a call
17059 to Executable_Prefix_Path.
17060 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is

17116 Expand_Limited_With_Clause): Use a new copy of selector name in the
17117 call to Make_With_Clause. This fixes the tree structure for ASIS
17118 purposes. Nothing is changed in the compiler behaviour.
17119 (Process_Body_Clauses): Handle properly use clauses whose prefix is
17120 a package renaming.
17121 (Install_Limited_With_Clauses): Do not install non-limited view when it
17122 is still incomplete.
17124 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17125 Gary Dismukes <dismukes@adacore.com>
17127 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
17128 when capturing size information, instead of base type, which for a
17129 formal array type will be the unconstrained type.
17130 (Analyze_Formal_Object_Declaration): Add check for illegal default
17131 expressions for a formal in object of a limited type.
17132 (Instantiate_Object): Ditto.
17133 (Check_Formal_Package_Instance): Skip entities that are formal objects,
17134 because they were defaulted in the formal package and no check applies
17136 (Check_Formal_Package_Instance): Extend conformance check to other
17137 discrete types beyond Integer.
17138 (Process_Default): Copy directly the unmatched formal. A generic copy
17139 has already been performed in Analyze_Formal_Package.
17140 (Analyze_Associations): If a formal subprogram has no match, check for
17141 partial parametrization before looking for a default, to prevent
17143 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
17144 not set the instantiation environment before analyzing the actuals.
17145 Fixes regression on 8515-003 with implementation of AI-133.
17146 Set_Instance_Env checks whether the generic unit is a predefined
17147 unit, in which case the instance must be analyzed with the latest Ada
17148 mode. This setting must take place after analysis of the actuals,
17149 because the actuals must be analyzed and frozen in the Ada mode extant
17150 outside of the current instantiation.
17151 (Save_Env, Restore_Env): Preserve and restore the configuration
17152 parameters so that predefined units can be compiled in the proper Ada

17165 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
17166 prefix type is a discriminated subtype of the type of the formal.
17167 (Analyze_Allocator): Collect all coextensions regardless of the context.
17168 Whether they can be allocated statically is determined in exp_ch4.
17169 (Analyze_Selected_Component): If the prefix is a limited view and the
17170 non-limited view is available, use the non-limited one.
17171 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
17172 therefore illegal), suggest a qualified expression rather than a type
17173 conversion, because a type conversion would be illegal in this context.
17174 (Anayze_Allocator): Trace recursively all nested allocators so that all
17175 coextensions are on the corresponding list for the root. Do no mark
17176 coextensions if the root allocator is within a declaration for a stack-
17177 allocated object, because the access discriminants will be allocated on
17179 (Analyze_Call): Remove restriction on calls to limited functions for the
17180 cases of generic actuals for formal objects, defaults for formal objects
17181 and defaults for record components.
17182 (Analyze_Allocator): Before analysis, chain coextensions on the proper
17183 element list. Their expansion is delayed until the enclosing allocator
17184 is processed and its finalization list constructed.
17185 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
17186 for an operation with the given name among the primitive operations of
17187 the corresponding record type.
17188 (Analyze_Selected_Component): If the prefix is a task type that
17189 implements an interface, and there is no entry with the given name,
17190 check whether there is another primitive operation (e.g. a function)
17192 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
17193 properly the indexing of a function call written in prefix form, where
17194 the function returns an array type, and all parameters of the function
17195 except the first have defaults.
17196 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
17197 the original operands, rather than relocating them, for efficiency and
17198 to work properly when an operand is overloaded.
17199 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
17200 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
17201 (Analyze_Selected_Component): If the prefix is a private extension, only
17202 scan the visible components, not those of the full view.
17203 (Try_Primitive_Operation): If the operation is a procedure, collect all
17204 possible interpretations, as for a function, because in the presence of
17205 classwide parameters several primitive operations of the type can match
17206 the given arguments.

17222 (Analyze_Package_Declaration): When the package declaration being
17223 analyzed does not require an explicit body, call Check_Completion.

17225 spec contains the declaration of a remote access-to-classwide type.
17226 (Analyze_Package_Body): If the package contains RACWs, append the
17227 pending subprogram bodies generated by exp_dist at the end of the body.

17233 * sem_dist.adb (Add_RAS_Dereference_TSS):
17234 Change primitive name to _Call so it cannot clash with any legal
17235 identifier, and be special-cased in Check_Completion.
17236 Mark the full view of the designated type for the RACW associated with
17237 a RAS as Comes_From_Source to get proper view switching when installing
17238 private declarations.
17239 Provite a placeholder nested package body along with the nested spec
17240 to have a place for Append_RACW_Bodies to generate the calling stubs
17241 and stream attributes.
17243 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17244 Robert Dewar <dewar@adacore.com>

17270 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
17271 dereference of a local object R created as a reference to another
17272 object O, use the access level of O.
17273 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
17274 rather than local Same_Formal_Type, to check whether protected operation
17275 overrides an inherited one.
17276 (Same_Formal_Type): New predicate, used when matching signatures of
17277 overriding synchronized operations, to handle the case when a formal
17278 has a type that is a generic actual.
17279 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
17280 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
17281 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
17282 syntactic ambiguities involving indexing of function calls that return

17293 (Is_Parent): New subprogram that determines whether E1 is a parent
17294 of E2. For a concurrent type its parent is the first element of its
17295 list of interface types; for other types this function provides the
17296 same result than Is_Ancestor.
17297 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
17298 (Collect_Synchronized_Interfaces): Removed because the subprogram
17299 Collect_Abstract_Interfaces provides this functionality.
17300 (Collect_Abstract_Interfaces): Minor update to give support to
17301 concurrent types and thus avoid undesired code duplication.
17302 (Get_Subprogram_Entity): Handle entry calls.
17303 (May_Be_Lvalue): Include actuals that appear as in-out parameters in

17345 high bound is constant and the slice is empty. Tidy.
17346 (tree_transform, case N_Op_Not): Handle properly the case where the
17347 operation applies to a private type whose full view is a modular type.
17348 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
17349 Address_Clause, use the associated Expression as the GNAT tree
17350 representing the choice value to ensure the corresponding GCC tree is
17351 of the proper kind.
17352 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
17353 instead of just the operands, as the base GCC stabilize_reference does.
17354 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
17355 requested; otherwise fail.
17356 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

17612 (Resolve_Arithmetic_Op): Do not give an error on calls to the
17613 universal_fixed "*" and "/" operators when they are used in a context
17614 that expects any real type. Also set the type of the node to

17616 (mainly static expression evaluation).
17617 Reword some continuation messages
17618 Add some \\ sequences to continuation messages
17619 (Resolve_Call): Refine infinite recursion case. The test has been

17633 during analysis, and use May_Be_Lvalue to distinguish read/write.
17634 (Valid_Array_Conversion): New procedure, abstracted from
17635 Valid_Conversion, to incorporate accessibility checks for arrays of
17636 anonymous access types.
17637 (Valid_Conversion): For a conversion to a numeric type occurring in an
17638 instance or inlined body, no need to check that the operand type is
17639 numeric, since this has been checked during analysis of the template.

18106 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
18107 mechargs instead of sigargs, as the latter can be retrieved from the

18155 (Set_All_DT_Position): Hidden entities associated with abstract
18156 interface primitives are not taken into account in the check for

18169 (Make_DT): If the ancestor of the type is a CPP_Class and we are
18170 compiling under full ABI compatibility mode we avoid the generation of
18171 calls to run-time services that fill the dispatch tables because under
18172 this mode we currently inherit the dispatch tables in the IP subprogram.
18173 (Write_DT): Emit an "is null" indication for a null procedure primitive.
18174 (Expand_Interface_Conversion): Use an address as the type of the formal
18175 of the internally built function that handles the case in which the

18226 we request a discriminal value only in case of discriminants.
18227 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
18228 assignments where the target subtype is unconstrained and the target
18229 object is a parameter or dereference (other aliased cases are known

18346 are build-in-place function calls.
18347 (Replace_Self_Reference): New subsidiary of
18348 Make_OK_Assignment_Statement, to replace an access attribute that is a
18349 self-reference into an access to the appropriate component of the
18350 target object. Generalizes previous mechanism to handle self-references
18351 nested at any level.
18352 (Is_Self_Referential_Init): Remove, not needed.

18359 default initialization.
18360 (Make_OK_Assignment_Statement): If the expression is of the form
18361 Typ'Acc, where Acc is an access attribute, the expression comes from a
18362 default initialized self-referential component.
18363 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
18364 that has been derived from several abstract interfaces we must also

18393 subcomponent's enclosing variable is aliased with a constrained subtype.
18394 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
18395 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
18396 an aliased prefix must be known to be constrained in order to use True
18397 for the attribute value, and now it's possible for some aliased views
18398 to be unconstrained.

18417 required to report the correct error message.
18418 (Expand_N_Subtype_Indication): Do validity checks on range
18419 (Clean_Task_Names): If an initialization procedure includes a call to

18429 Object_Declaration to the call.
18430 (Freeze_Type): When the designated type of an RACW was not frozen at the
18431 point where the RACW was declared, validate the primitive operations
18432 with respect to E.2.2(14) when it finally is frozen.
18433 (Build_Initialization_Call,Expand_Record_Controller): Rename
18434 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18435 return-by-reference has no meaning in Ada 2005.

18437 to register tag of the immediate ancestor interfaces in the
18438 run-time structure.

18440 initialization of extension aggregates with abstract interfaces.
18441 (Build_Master_Renaming): Make public, for use by function declarations
18442 whose return type is an anonymous access type.
18443 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18444 Insert_List_Before_And_Analyze after the generation of the specs
18445 associated with null procedures.

18447 (Init_Secondary_Tags): Update documentation.
18448 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18449 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18450 then generate code to inherit the contents of the dispatch table
18451 directly from the ancestor.
18452 (Expand_Record_Controller): Insert controller component after tags of
18453 implemented interfaces.

18459 (Is_Null_Interface_Procedure): New function in
18460 Make_Null_Procedure_Specs.
18461 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18462 immediate ancestor of a tagged type is an abstract interface type we
18463 must generate the specification of the predefined primitives associated
18464 with controlled types (because the dispatch table of the ancestor is
18465 null and hence these entries cannot be inherited). This is required to
18466 elaborate well the dispatch table.

18480 the maximum for type T.
18481 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18482 when the allocator is initialized by a build-in-place call, since the
18483 allocator is already rewritten as a reference to the function result,
18484 and this prevents an unwanted duplication of the function call.
18485 Add with and use of Exp_Ch6.
18486 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18487 is a call to build-in-place function and apply
18488 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18489 untagged designated types).
18490 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18491 optimization if source or target is biased.

18510 in order to alleviate the upward compatibility introduced by AI-318.
18511 (Expand_N_Extended_Return_Statement): Add support for handling the
18512 return object as a build-in-place result.
18513 (Expand_Non_Function_Return): Implement simple return statements nested
18514 within an extended return.
18515 (Enable_New_Return_Processing): Turn on the new processing of return
18517 (Expand_Non_Function_Return): For a return within an extended return,
18518 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18519 (Expand_N_Extended_Return_Statement): Implement AI-318
18520 (Expand_Simple_Function_Return): Ditto.
18521 (Expand_N_If_Statement): Handle new -gnatwt warning
18522 (Expand_N_Case_Statement): Handle new -gnatwt warning
18523 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18524 a protected object.
18525 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18526 validity checking of assignments to elementary record components.
18527 (Expand_N_Return_Statement): return Class Wide types on the secondary
18528 stack independantly of their controlled status since with HIE runtimes,
18529 class wide types are not potentially controlled anymore.
18531 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18534 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18535 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18536 it expects a block, procedure, or task. The return statement will get
18537 turned into a block, and Expand_Cleanup_Actions will happen then.

18540 Ed Schonberg <schonberg@adacore.com>
18541 Bob Duff <duff@adacore.com>
18542 Gary Dismukes <dismukes@adacore.com>
18544 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18546 (Expand_Inlined_Call): Tagged types are by-reference types, and
18547 therefore should be replaced by a renaming declaration in the expanded
18548 body, as is done for limited types.
18549 (Expand_Call): If this is a call to a function with dispatching access
18550 result, propagate tag from context.
18551 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18553 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18554 build-in-place when the right-hand side of an assignment is a
18555 build-in-place function call.
18556 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18557 of the explicit dereference of the allocator to the result subtype of
18558 the build-in-place function. This is needed to satisfy type checking
18559 in cases where the caller's return object is created by an allocator for
18560 a class-wide access type and the type named in the allocator is a
18562 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18563 conversion of the reference to the declared object to the result subtype
18564 of the build-in-place function. This is needed to satisfy type checking
18565 in cases where the declared object has a class-wide type. Also, in the
18566 class-wide case, change the type of the object entity to the specific
18567 result subtype of the function, to avoid passing a class-wide object
18568 without explicit initialization to the back end.
18569 (Register_Interface_DT_Entry): Moved outside the body of
18570 Freeze_Subprogram because this routine is now public; it is called from
18571 Check_Dispatching_Overriding to handle late overriding of abstract
18572 interface primitives.
18573 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18574 adding an implicit access actual on a call to a build-in-place function.
18575 (Expand_Actuals): Test for an actual parameter that is a call to a
18576 build-in-place function and apply
18577 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18578 (Is_Build_In_Place_Function): New function to determine whether an
18579 entity is a function whose calls should be handled as build-in-place.
18580 (Is_Build_In_Place_Function_Call): New function to determine whether an
18581 expression is a function call that should handled as build-in-place.
18582 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18583 calls to build-in-place functions as the initialization of an allocator.
18584 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18585 handling calls to build-in-place functions in contexts that do not
18586 involve init of a separate object (for example, actuals of subprogram
18588 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18589 handling calls to build-in-place functions as the initialization of an
18590 object declaration.
18591 (Detect_Infinite_Recursion): Add explicit parameter Process to
18592 instantiation of Traverse_Body to avoid unreferenced warning.
18593 (Check_Overriding_Inherited_Interfaces): Removed.
18594 (Register_Interface_DT_Entry): Code cleanup.
18595 (Register_Predefined_DT_Entry): Code cleanup.
18596 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18597 inlined statements if within a transient scope.
18598 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18599 formal parameters with occurrences of actuals in inlined body, establish
18600 visibility on the proper view of the actual's subtype for the body's
18602 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18603 compatibility mode and we have an imported CPP subprogram because
18604 for now we assume that imported CPP primitives correspond with
18605 objects whose constructor is in the CPP side (and therefore we
18606 don't need to generate code to register them in the dispatch table).
18607 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18608 aligned selected component.
18609 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18610 the actual of an in-mode parameter is a type conversion.
18611 (Expand_Actuals): If the call does not come from source and the actual
18612 is potentially misaligned, let gigi handle it rather than rejecting the
18613 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18614 Class Wide types as returning by reference independantly of their
18615 controlled status since with HIE runtimes class wide types are not
18616 potentially controlled anymore.
18618 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18620 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
18621 references that are private components of the protected object.
18622 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
18623 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18624 instantiation to deal with warnings.
18625 (Initialize_Protection): If expression for priority is non-static, use
18626 System_Priority as its expected type, in case the expression has not
18629 2006-10-31 Robert Dewar <dewar@adacore.com>
18631 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18632 initialization of Homonym_Len.
18633 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18634 names from fully qualified name. Fixes problem of duplicate
18635 external names differing only in the presence of such a block name.
18637 2006-10-31 Thomas Quinot <quinot@adacore.com>
18638 Pablo Oliveira <oliveira@adacore.com>
18640 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18641 subprogram Ids, even if they are not yet assigned.
18642 (Build_Subprogram_Id): It is now this function that will take care of
18643 calling Assign_Subprogram_Ids if necessary.
18644 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18645 should be done only once they are assigned.
18646 (Build_From_Any_Function, case of tagged types): Add missing call to
18648 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18649 type for an RACW type.
18650 (Add_RACW_Features): When processing an RACW declaration for which the
18651 designated type is already frozen, enforce E.2.2(14) rules immediately.
18652 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18653 special reordering of controlling formals.
18655 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18656 associated stub type for an RACW type.
18658 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18660 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18661 fixed-point operations in an integer context, i.e. as operands of a
18662 conversion to an integer type, indicate that result must be rounded.
18664 2006-10-31 Robert Dewar <dewar@adacore.com>
18666 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18667 cases, pass the encoding method, since it is now required by the run
18670 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18671 assumption that Str'First = 1.
18672 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18673 it on to the Value_Wide_Wide_Character call.
18674 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18675 properly handles a string of the form quote-encoded_wide_char-quote.
18677 * s-wchcnv.adb: Minor reformatting
18679 2006-10-31 Javier Miranda <miranda@adacore.com>
18681 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18682 run-time membership test to ensure that the constructed object
18683 implements the target abstract interface.
18685 2006-10-31 Robert Dewar <dewar@adacore.com>
18687 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18688 Machine_Attribute pragma internally to implement the user pragma.
18689 Add processing for pragma Interface so that it is now completely
18690 equivalent to pragma Import.
18692 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18693 so that it can be applied to all entities, including record components
18694 and enumeration literals.
18695 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18696 priority ranges are correct, verify compatibility against task
18697 dispatching and locking policies, and if everything is correct an entry
18698 is added to the table containing priority specific dispatching entries
18699 for this compilation unit.
18700 (Delay_Config_Pragma_Analyze): Delay processing
18701 Priority_Specific_Dispatching pragmas because when processing the
18702 pragma we need to access run-time data, such as the range of
18703 System.Any_Priority.
18704 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18705 Allow pragma Unreferenced as a context item
18706 Add pragma Preelaborable_Initialization
18707 (Analyze_Pragma, case Interface): Interface is extended so that it is
18708 now syntactically and semantically equivalent to Import.
18709 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18710 insertion characters.
18711 Add handling for Pragma_Wide_Character_Encoding
18712 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18713 never supercedes a real restriction, and that a real restriction
18714 always supercedes a warning.
18715 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

18719 Ed Schonberg <schonberg@adacore.com>
18720 Robert Dewar <dewar@adacore.com>
18722 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18723 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18724 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18726 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18727 type of the function containing a return statement, because the
18728 Return_Type field was removed. We now use the Return_Applies_To field.
18730 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18731 (Build_Task_Image_Decl): If procedure is not called from an
18732 initialization procedure, indicate that function that builds task name
18733 uses the sec. stack. Otherwise the enclosing initialization procedure
18734 will carry the indication.
18735 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18736 N_Object_Declaration instead.
18737 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18738 conditional dead code killed, and change implementation accordingly.
18739 (Insert_Actions): Add N_Return_Object_Declaration case.
18740 Correct comment to mention N_Extension_Aggregate node.
18741 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18742 attempts to save information for global variables which cannot be
18744 (Get_Current_Value_Condition): Handle conditions the other way round
18745 (constant on left). Also handle right operand of AND and AND THEN
18746 (Set_Current_Value_Condition): Corresponding changes
18747 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18748 (Get_Current_Value_Condition): Handle simple boolean operands
18749 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18750 (Get_Current_Value_Condition): If the variable reference is within an
18751 if-statement, does not appear in the list of then_statments, and does
18752 not come from source, treat it as being at unknown location.
18753 (Get_Current_Value_Condition): Enhance to allow while statements to be
18754 processed as well as if statements.
18755 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18757 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18758 of loop. This is safe now that we fixed Kill_Current_Values.
18759 (OK_To_Do_Constant_Replacement): Check whether current scope is
18760 Standard, before examining outer scopes.
18762 2006-10-31 Vincent Celier <celier@adacore.com>
18764 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18765 When True, apply VMS treatment to children of packages A, G, I and S.
18768 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18770 2006-10-31 Robert Dewar <dewar@adacore.com>
18771 Ed Schonberg <schonberg@adacore.com>
18773 * freeze.adb: Add handling of Last_Assignment field
18774 (Warn_Overlay): Supply missing continuation marks in error msgs
18775 (Freeze_Entity): Add check for Preelaborable_Initialization
18777 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18779 * g-expect.adb: Add Warnings (Off) to prevent new warning
18781 * lib-xref.adb: Add handling of Last_Assignment field
18782 (Generate_Reference): Centralize handling of pragma Obsolescent here
18783 (Generate_Reference): Accept an implicit reference generated for a
18784 default in an instance.
18785 (Generate_Reference): Accept a reference for a node that is not in the
18786 main unit, if it is the generic body corresponding to an subprogram
18789 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18791 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18793 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18795 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18796 use clauses, to avoid messages on packages used to qualify, and also
18797 to avoid messages from obsolescent units.
18798 (Warn_On_Useless_Assignments): Don't generate messages for imported
18799 and exported variables.
18800 (Warn_On_Useless_Assignments): New procedure
18801 (Output_Obsolescent_Entity_Warnings): New procedure
18802 (Check_Code_Statement): New procedure
18804 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18805 Change name Is_Ada_2005 to Is_Ada_2005_Only
18806 (Last_Assignment): New field for useless assignment warning
18808 2006-10-31 Olivier Hainque <hainque@adacore.com>
18810 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18811 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18813 2006-10-31 Bob Duff <duff@adacore.com>
18814 Robert Dewar <dewar@adacore.com>
18815 Ed Schonberg <schonberg@adacore.com>
18817 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18818 Ada 95 mode, because it violates the new rules for AI-318.
18820 * g-awk.ads: Use overloaded subprograms in every case where we used to
18821 have a default of Current_Session. This makes the code closer to be
18822 correct for both Ada 95 and 2005.
18824 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18825 code, relying on the fact that the compiler generates a warning
18826 instead of an error in -gnatg mode.
18828 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18829 E_Return_Statement entity kind.
18830 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18832 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18833 report an error if the reserved word abstract has been previously found.
18834 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18836 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18837 parenthesized range attribute usage
18838 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18840 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18841 in the syntax for extended_return_statement. This is not in the latest
18842 RM, but the ARG is expected to issue an AI allowing this.
18843 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18844 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18845 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18846 P_Return_Statement): Parse the new syntax for extended_return_statement.
18848 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18849 Output_End_Missing): Add error-recovery code for the new
18850 extended_return_statement syntax; that is, the new E_Return entry on
18853 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18854 limited to nonlimited, because otherwise we violate the new Ada 2005
18855 rules about returning limited types in function Create_AST_Handler in
18858 * sem.adb (Analyze): Add cases for new node kinds
18859 N_Extended_Return_Statement and N_Return_Object_Declaration.
18861 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18862 type is in the same category as type of context before applying check,
18863 to prevent anomalies in instantiations.
18864 (Resolve_Aggregate): Remove test for limited components in aggregates.
18865 It's unnecessary in Ada 95, because if it has limited components, then
18866 it must be limited. It's wrong in Ada 2005, because limited aggregates
18868 (Resolve_Record_Aggregate): Move check for limited types later, because
18869 OK_For_Limited_Init requires its argument to have been resolved.
18870 (Get_Value): When copying the component default expression for a
18871 defaulted association in an aggregate, use the sloc of the aggregate
18872 and not that of the original expression, to prevent spurious
18873 elaboration errors, when the expression includes function calls.
18874 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18875 were missing. We also didn't handle qualified expressions. Now also
18876 allow function calls. Use new common routine OK_For_Limited_Init.
18877 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18878 with space can upper case letter).
18880 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18881 Has_Static_Discriminants flag
18882 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18883 type with discriminants.
18884 (Process_Range_Expr_In_Decl): Do validity checks on range
18885 (Build_Discriminant_Constraints): Use updated form of
18886 Denotes_Discriminant.
18887 (Process_Subtype): If the subtype is a private subtype whose full view
18888 is a concurrent subtype, introduce an itype reference to prevent scope
18890 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18891 Record_Type_Declaration): The functionality of the subprograms
18892 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18893 is now performed by a single routine.
18894 (Build_Derived_Record_Type): If the type definition includes an explicit
18895 indication of limitedness, then the type must be marked as limited here
18896 to ensure that any access discriminants will not be treated as having
18897 a local anonymous access type.
18898 (Check_Abstract_Overriding): Issue a detailed error message when an
18899 abstract subprogram was not overridden due to incorrect mode of its
18901 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18902 synchronized private extension declarations. Verify that the ancestor is
18903 a limited or synchronized interface or in the generic case, the ancestor
18904 is a tagged limited type or synchronized interface and all progenitors
18905 are either limited or synchronized interfaces.
18906 Derived_Type_Declaration): Check for presence of private extension when
18907 dealing with synchronized formal derived types.
18908 Process_Full_View): Enchance the check done on the usage of "limited" by
18909 testing whether the private view is synchronized.
18910 Verify that a synchronized private view is completed by a protected or
18912 (OK_For_Limited_Init_In_05): New function.
18913 (Analyze_Object_Declaration): Move check for limited types later,
18914 because OK_For_Limited_Init requires its argument to have been resolved.
18915 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18916 in order to alleviate the upward compatibility introduced by AI-318.
18917 (Constrain_Corresponding_Record): If the constraint is for a component
18918 subtype, mark the itype as frozen, to avoid out-of-scope references to
18919 discriminants in the back-end.
18920 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18921 this subprogram against wrong sources.
18922 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18923 discriminant of limited type completed with a protected type, when the
18924 discriminant is used to constrain a private component of the type, and
18925 expansion is disabled.
18926 (Find_Type_Of_Object): Do not treat a return subtype that is an
18927 anonymous subtype as a local_anonymous_type, because its accessibility
18928 level is the return type of the enclosing function.
18929 (Check_Initialization): In -gnatg mode, turn the error "cannot
18930 initialize entities of limited type" into a warning.
18931 (OK_For_Limited_Init): Return true for generated nodes, since it
18932 sometimes violates the legality rules.
18933 (Make_Incomplete_Declaration): If the type for which an incomplete
18934 declaration is created happens to be the currently visible entity,
18935 preserve the homonym chain when removing it from visibility.
18936 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18937 inherited subprograms.
18938 (Access_Definition): If this is an access to function that is the return
18939 type of an access_to_function definition, context is a type declaration
18940 and the scope of the anonymous type is the current one.
18941 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18942 incomplete subtype to the set of private dependents of the original
18944 (Constrain_Discriminated_Type): Emit an error message whenever an
18945 incomplete subtype is being constrained.
18946 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18947 corresponding subtype of the full view of the original incomplete type.
18948 (Check_Incomplete): Properly detect invalid usage of incomplete types

18962 Robert Dewar <dewar@adacore.com>
18964 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18965 handling executable extension manually and duplicating code.
18967 * make.adb: Implement new -S switch
18968 (Gnatmake): Use new function Osint.Executable_Name instead
18969 of handling executable extension manually.
18971 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18972 is specified, the executable name ends with this suffix.
18973 Take advantage of Osint.Executable_Name instead of duplicating code.

18986 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18987 call it with -static-libgcc, as there are some platforms, such as
18988 Darwin, where one of these two switches is compulsory to link.
18990 2006-10-31 Vincent Celier <celier@adacore.com>
18992 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18993 instead of ADA_PROJECT_PATH, for the project path.
18994 (Gnatls): When displaying the project path directories, use host dir
18997 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18998 names in the project path, as absolute paths may correspond to
18999 multi-valued VMS logical names.

19030 2006-10-31 Robert Dewar <dewar@adacore.com>
19032 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
19034 (Layout_Variant_Record): Retrieve the discriminants from the entity
19035 rather than from the type definition, because in the case of a full
19036 type for a private type we need to take the discriminants from the
19038 (Layout_Component_List): When applying the Max operator to variants with
19039 a nonstatic size, check whether either operand is static and scale that
19040 operand from bits to storage units before applying Max.
19041 (Layout_Type): In VMS, if a C-convention access type has no explicit
19042 size clause (and does not inherit one in the case of a derived type),
19043 then the size is reset to 32 from 64.
19045 2006-10-31 Vincent Celier <celier@adacore.com>
19047 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
19048 its file has already been loaded, according to the unit being loaded,
19049 not to the current value of Multiple_Unit_Index.

19079 * mlib-utl.adb (Initialized): Remove, no longer used
19080 (Initialize): Remove, no longer used
19081 (Ar): If Ar_Exec is null, get the location of the archive builder and,

19084 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
19087 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19089 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
19090 Process_Body_Clauses): If the context of a body includes a use clause
19091 for P.Q then a with_clause for P in the same body is not redundant,
19092 even if the spec also has a with_clause on P.
19093 Add missing continuation mark to error msg
19094 (Build_Limited_Views): A limited view of a type is tagged if its
19095 declaration includes a record extension.
19096 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
19097 node, even if the subunit has errors. This avoids malfunction by
19098 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
19099 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
19100 generation of obsolescent messages for with statements (cannot do
19101 this too early, or we cannot implement avoiding the messages in the
19102 case of obsolescent units withing obsolescent units).
19103 (Install_Siblings): If the with_clause is on a remote descendant of
19104 an ancestor of the current compilation unit, find whether there is
19105 a sibling child unit that is immediately visible.
19106 (Remove_Private_With_Clauses): New procedure, invoked after completing
19107 the analysis of the private part of a nested package, to remove from
19108 visibility the private with_clauses of the enclosing package
19110 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
19111 now centralized in Generate_Reference.
19112 (Install_Limited_Context_Clauses): Remove superfluous error
19113 message associated with unlimited view visible through use
19114 and renamings. In addition, at the point in which the error
19115 is reported, we add the backslash to the text of the error
19116 to ensure that it is reported as a single error message.
19117 Use new // insertion for some continuation messages
19118 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
19119 to create implicit with_clause for parent unit mentioned in original
19120 limited_with_clause.
19121 (Install_Limited_With_Unit): Set entity of parent identifiers if the
19122 unit is a child unit. For ASIS queries.
19123 (Analyze_Subunit): If the subunit appears within a child unit, make all
19124 ancestor child units directly visible again.

19139 a formal object declaration with an access definition or a subtype mark
19140 with a null exclusion.
19141 (P_Generic_Association): Handle association with box, and others_choice
19142 with box, to support Ada 2005 partially parametrized formal packages.
19144 2006-10-31 Robert Dewar <dewar@adacore.com>
19145 Javier Miranda <miranda@adacore.com>
19147 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
19148 (P_Type_Declaration): Remove barrier against the reserved word "limited"
19149 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
19150 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
19151 private extensions.
19152 (P_Type_Declaration): Add the new actual Abstract_Present to every call
19153 to P_Interface_Type_Definition.
19154 (P_Interface_Type_Definition): Addition of one formal to report an error
19155 if the reserved word abstract has been previously found.
19156 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
19157 object renaming declaration with an access definition or subtype mark
19158 with a possible null exclusion.

19177 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
19180 2006-10-31 Vincent Celier <celier@adacore.com>
19182 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
19183 on VMS, change "__" to '.' before checking the name.
19184 (Record_Ada_Source): Always add the source file name in the list of
19185 of sources, even if it is not the first time, as it is for another
19187 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
19188 dot, instead of replacing only the first '_'.
19190 * prj-part.adb (Parse): Convert project file path to canonical form
19192 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
19193 extended, the project id of the project extending it is recorded in its
19194 data, even when it has already been processed as an imported project.
19196 2006-10-31 Robert Dewar <dewar@adacore.com>
19198 * repinfo.adb (List_Entities): Don't list entities from renaming
19201 2006-10-31 Arnaud Charlet <charlet@adacore.com>
19202 Robert Dewar <dewar@adacore.com>
19204 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
19205 only a restriction warning is active for the given restriction. This is
19206 desirable because we do not want to modify code in the case where only
19208 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
19209 causes overriding of real restrictions.
19210 Take advantage of new No_Restrictions constant.
19212 * raise.h: (__gnat_set_globals): Change profile.
19214 2006-10-31 Arnaud Charlet <charlet@adacore.com>
19216 * rtsfind.adb: Remove s-polint from comment as it exists no more.
19219 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
19220 Move all the entities in obsolete package System.PolyORB_Interface to
19221 System.Partition_Interface.

19235 Thomas Quinot <quinot@adacore.com>
19236 Javier Miranda <miranda@adacore.com>
19237 Gary Dismukes <dismukes@adacore.com>
19239 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
19240 properly an attempt to apply Unchecked_Access to a protected operation.
19241 (OK_Self_Reference): New subprogram to check the legality of an access
19242 attribute whose prefix is the type of an enclosing aggregate.
19243 Generalizes previous mechanism to handle attribute references nested
19244 arbitrarily deep within the aggregate.
19245 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19246 can appear in an aggregate if this is a default-initialized aggregate
19247 for a self-referential type.
19248 (Resolve_Attribute, case Access): Ditto.
19249 Add support for new implementation defined attribute Stub_Type.
19250 (Eval_Attribute, case Attribute_Stub_Type): New case.
19251 (Analyze_Attribute, case Attribute_Stub_Type): New case.
19252 (Stream_Attribute_Available): Implement using new subprogram from
19253 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
19254 Has_Specified_Stream_Attribute flag.
19255 Disallow Storage_Size and Storage_Pool for access to subprogram
19256 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19257 access types of return subtypes in extended return statements. Remove
19258 accessibility checks on anonymous access types when Unchecked_Access is
19260 (Analyze_Attribute): Add support for the use of 'Class to convert
19261 a class-wide interface to a tagged type.
19262 Add support for the attribute Priority.
19263 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19264 whether the designated type is discriminated with a constrained partial
19265 view and require static matching in that case.
19266 Add local variable Des_Btyp. The Designated_Type
19267 of an access to incomplete subtype is either its non-limited view if
19268 coming from a limited with or its etype if regular incomplete subtype.
19270 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19271 Fix predicate to identify and allow cases of (expander-generated)
19272 references to tag of designated object of a RACW.
19273 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19274 non-static, and therefore cannot appear as a primary in a preelaborable
19276 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
19277 Has_Read_Write_Attributes.
19278 (Has_Read_Write_Attributes): Reimplement in termes of
19279 Has_Stream_Attribute_Definition.
19280 (Missing_Read_Write_Attributes): When checking component types in a
19281 record, unconditionally call Missing_Read_Write_Attributes recursively
19282 (remove guard checking for Is_Record_Type / Is_Access_Type).
19284 2006-10-31 Robert Dewar <dewar@adacore.com>
19286 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
19287 useless assignments here and conditionalize it on absence of exception
19289 (Analyze_Exception_Handlers): Small code reorganization of error
19290 detection code, for new handling of formal packages.
19292 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19293 Hristian Kirtchev <kirtchev@adacore.com>
19295 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
19296 that has been constant-folded, preserve information of original tree,
19298 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
19299 generated private extension declaration if the formal derived type is
19300 synchronized. Carry synchronized present over to the generated private
19302 (Validate_Derived_Type_Instance): Ensure that the actual of a
19303 synchronized formal derived type is a synchronized tagged type.
19304 (Instantiate_Formal_Package): When creating the instantiation used to
19305 validate the actual package of a formal declared without a box, check
19306 whether the formal itself depends on a prior actual.
19307 (Instantiate_Formal_Subprogram): Create new entities for the defining
19308 identifiers of the formals in the renaming declaration, for ASIS use.
19309 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19310 a renaming declaration or a subtype declaration for an actual in an
19311 instance, capture location information of declaration in generic, for
19313 (Instantiate_Formal_Package): Add comments on needed additional tests.
19314 AI-317 (partial parametrization) is fully implemented.
19315 (Validate_Private_Type_Instance): Add check for actual which
19316 must have preelaborable initialization
19317 Use new // insertion for some continuation messages
19318 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19319 Default_Expression. Add type retrieval when the declaration has an
19320 access definition. Update premature usage of incomplete type check.
19321 (Check_Access_Definition): New subsidiary routine. Check whether the
19322 current compilation version is Ada 05 and the supplied node has an
19324 (Instantiate object): Alphabetize local variables. Handle the creation
19325 of new renaming declarations with respect to the kind of definition
19326 used - either an access definition or a subtype mark. Guard against
19327 unnecessary error message in the context of anonymous access types after
19328 they have been resolved. Add check for required null exclusion in a
19329 formal object declaration.
19330 (Switch_View): A private subtype of a non-private type needs to be
19331 switched (the base type can have been switched without its private
19332 dependents because of the last branch of Check_Private_View.
19333 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19335 (Instantiate_Type): Emit an error message whenever a class-wide type of
19336 a tagged incomplete type is used as a generic actual.
19337 (Find_Actual_Type): Extend routine to handle a component type in a child
19338 unit that is imported from a formal package in a parent.
19339 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19340 agree on constrainedness, rather than checking against ultimate ancestor
19341 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19342 generic body, for navigation purposes.
19344 2006-10-31 Robert Dewar <dewar@adacore.com>
19345 Thomas Quinot <quinot@adacore.com>
19347 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
19349 (New_Stream_Subprogram): When processing an attribute definition clause
19350 for a stream-oriented subprogram, record an entity node occurring at
19351 the point of clause to use for checking the visibility of the clause,
19352 as defined by 8.3(23) as amended by AI-195.
19353 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19354 New_Stream_Function and New_Stream_Procedure.
19355 (New_Stream_Function, New_Stream_Procedure): Removed.
19356 (Analyze_Attribute_Definition_Clause, case Address): Check new
19357 Alignment_Check check
19359 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19360 Javier Miranda <miranda@adacore.com>
19361 Robert Dewar <dewar@adacore.com>
19363 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19364 generate the same errors compiling under -gnatc.
19365 (Try_Object_Operation): If no candidate interpretation succeeds, but
19366 there is at least one primitive operation with the right name, report
19367 error in call rather than on a malformed selected component.
19368 (Analyze_Selected_Component): If the prefix is an incomplete type from
19369 a limited view, and the full view is available, use the full view to
19370 determine whether this is a prefixed call to a primitive operation.
19371 (Operator_Check): Verify that a candidate interpretation is a binary
19372 operation before checking the type of its second formal.
19373 (Analyze_Call): Add additional warnings for function call contexts not
19375 (Analyze_Allocator): Move the check for "initialization not allowed for
19376 limited types" after analyzing the expression. This is necessary,
19377 because OK_For_Limited_Init looks at the structure of the expression.
19378 Before analysis, we don't necessarily know what sort of expression it
19379 is. For example, we don't know whether F(X) is a function call or an
19380 indexed component; the former is legal in Ada 2005; the latter is not.
19381 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19382 were missing. We also didn't handle qualified expressions. Now also
19383 allow function calls. Use new common routine OK_For_Limited_Init.
19384 (Analyze_Type_Conversion): Do not perform some legality checks in an
19385 instance, because the error message will be redundant or spurious.
19386 (Analyze_Overloaded_Selected_Component): Do not do style check when
19387 setting an entity, since we do not know it is the right entity yet.
19388 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19389 (Analyze_Overloaded_Selected_Component): Same change
19390 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19391 since regular incomplete subtypes are transformed into corresponding
19392 subtypes of their full views.
19393 (Complete_Object_Operation): Treat name of transformed subprogram call
19394 as coming from source, for browsing purposes.
19395 (Try_Primitive_Operation): If formal is an access parameter, compare
19396 with base type of object to determine whether it is a primitive
19398 (Operator_Check): If no interpretation of the operator matches, check
19399 whether a use clause on any candidate might make the operation legal.
19400 (Try_Class_Wide_Operation): Check whether the first parameter is an
19401 access type whose designated type is class-wide.
19403 2006-10-31 Robert Dewar <dewar@adacore.com>
19404 Ed Schonberg <schonberg@adacore.com>

19408 warn on infinite loops.
19409 Add \\ to some continuation messages
19410 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19411 (Process_Bounds): If the bounds are integer literals that result from
19412 constant-folding, and they carry a user-defined type, preserve that type
19413 rather than treating this as an integer range.
19414 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.

19423 or AND THEN for possible tracking.
19424 (Analyze_Iteration_Scheme): Check for setting Current_Value for the

19429 Bob Duff <duff@adacore.com>
19431 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19432 procedure cannot be a protected operation (it is a basic_declaration,
19433 not a subprogram_declaration).
19434 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19435 Subp. Add logic for entry processing.
19436 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.

19447 entity, scope, and name suffix, and handle setting of the new
19448 Extra_Formals field.
19449 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19450 pass new parameters. Add support for adding the new extra access formal
19451 for functions whose calls are treated as build-in-place.
19452 (Analyze_A_Return_Statement): Correct casing in error message.
19453 Move Pop_Scope to after Analyze_Function_Return, because an extended
19454 return statement really is a full-fledged scope. Otherwise, visibility
19455 doesn't work right. Correct use of "\" for continuation messages.
19456 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19457 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19458 the node doesn't get properly marked as analyzed.
19459 (Analyze_Subprogram_Body): If subprogram is a function that returns
19460 an anonymous access type that denotes a task, build a Master Entity
19462 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19463 proper usage of null exclusion in a result definition.

19472 homonym chain if it corresponds with an abstract interface primitive.
19473 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19474 call to the synthesized predicate Is_Incomplete_Type.
19475 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19477 (Analyze_Subprogram_Declaration): Check that abstract interface
19478 primitives are abstract or null.
19479 (Analyze_Subprogram_Specification): Remove previous check for abstract
19480 interfaces because it was not complete.
19481 (Has_Interface_Formals): Removed.

19486 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
19487 of Analyze_Package_Body, to create Itype references for anonymous
19488 access types created in the package declaration, whose designated types
19489 may have only a limited view.
19490 (Analyze_Package_Specification): For the private part of a nested
19491 package, install private_with_clauses of enclosing compilation unit if
19492 we are in its visible part.
19493 (Declare_Inherited_Private_Subprograms): Complete barrier
19494 to ensure that the primitive operation has an alias to some parent
19495 primitive. This is now required because, after the changes done for the
19496 implementation of abstract interfaces, the contents of the list of
19497 primitives has entities whose alias attribute references entities of
19498 such list of primitives.
19499 (Analyze_Package_Specification): Simplify code that handles parent units
19500 of instances and formal packages.
19501 (Uninstall_Declarations): Check the convention consistency among
19502 primitive overriding operations of a tagged record type.

19516 as potentially use-visible.
19517 (Find_Type): Handle the case of an attribute reference for
19518 implementation defined attribute Stub_Type (simply let the analysis of
19519 the attribute reference rewrite it).
19520 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
19521 type that appears in a Use_Type clause.
19522 (Analyze_Object_Renaming): Add support for renaming of the Priority

19525 when it appears in an access definition.
19526 (Analyze_Object_Renaming): Remove warning on null_exclusion.
19527 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19528 in a formal object declaration or in a subtype declaration.
19529 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19530 (Check_Null_Exclusion): New local routine to
19531 Analyze_Subprogram_Renaming. Check whether the formals and return
19532 profile of a renamed subprogram have required null exclusions when
19533 their counterparts of the renaming already impose them.
19534 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19535 Determine whether an entity is inside a generic scope.
19536 (In_Open_Scope): First pass of documentation update.
19537 (Find_Expanded_Name): Add support for shadow entities associated with
19538 limited withed packages. This is required to handle nested packages.
19539 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
19540 that makes a renaming of a limited withed package illegal.

19543 Ed Schonberg <schonberg@adacore.com>
19545 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
19546 Check_Overriding_Indicator.
19547 (Analyze_Task_Definition): Ditto.
19548 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19549 (Check_Overriding_Indicator): To find overridden interface operation,
19550 examine only homonyms that have an explicit subprogram declaration, not
19551 inherited operations created by an unrelated type derivation.
19552 (Check_Overriding_Indicator): When checking for the presence of "null"
19553 in a procedure, ensure that the queried node is a procedure

19556 type when the formal is an access to variable.
19557 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19558 (Analyze_Task_Type): Same addition
19559 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
19560 provide navigation capabilities for entries.

19567 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
19568 inherited from an interface ancestor by another interface in the
19569 context of an instance as 'late'.

19571 of a call to a function that dispatches on access result.
19572 (Check_Dispatching_Operation): In case of late overriding of a primitive
19573 that covers abstract interface subprograms we register it in all the
19574 secondary dispatch tables associated with abstract interfaces.
19575 (Check_Dispatching_Call): Add check that a dispatching call is not made
19576 to a function with a controlling result of a limited type. This is a
19577 current implementation restriction.
19578 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
19579 (Check_Dispatching_Operation): Do no emit a warning if the controlling
19580 argument is an interface type that is a generic formal.
19581 (Is_Interface_Subprogram): Removed.
19582 (Check_Dispatching_Operation): If the subprogram is not a dispatching
19583 operation, check the formals to handle the case in which it is
19584 associated with an abstract interface type.

19602 Javier Miranda <miranda@adacore.com>
19604 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve

19606 (Covers): Handle coverage of formal and actual anonymous access types in
19607 the context of generic instantiation.
19608 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
19609 abstract interface types; this is required to handle concurrent types

19626 qualification from an expression. There are numerous places where this
19627 ought to be used, but we currently only deal properly with zero or one
19629 (In_Instance); The analysis of the actuals in the instantiation of a
19630 child unit is not within an instantiation, even though the parent
19631 instance is on the scope stack.

19634 (Check_Obsolescent): Removed
19635 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

19713 (N_Extended_Return_Statement): New node for extended_return_statement
19715 (N_Return_Object_Declaration): New node for part of

19889 * a-rttiev.ads, a-rttiev.adb:
19890 This is a significant redesign primarily for the sake of automatic
19891 timer task termination but also to fix a design flaw.
19892 Therefore we are now using an RTS lock, instead of a protected
19893 object, to provide mutual exclusion to the queue of pending events
19894 and the type Timing_Event is no longer a protected type.

20401 evaluate the conversion at run-time.
20402 (Resolve_Equality_Op): Do not apply previous

20742 other basic tools. The full version that includes the Ada 2005 stuff

21069 positive. Also add checks against invalid values, and support for kb,
21070 mb. Ditto for -D switch.
21072 2006-02-13 Robert Dewar <dewar@adacore.com>
21073 Serguei Rybin <rybin@adacore.com>
21075 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
21076 save/restore routines.
21077 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

21079 Since we are changing the tree format anyway, also get rid of the
21080 junk obsolete Immediate_Errors flag.
21081 (Tree_Read): Change the way of reading Tree_Version_String - now we

21155 2006-02-13 Robert Dewar <dewar@adacore.com>
21157 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
21158 attribute Mechanism_Code is applied to renamed subprogram, modify
21159 prefix to point to base subprogram.
21160 Max/Min attributes now violate Restriction No_Implicit_Conditionals
21162 * sinfo.ads: Document that Mechanism_Code cannot be applied to
21163 renamed subprograms so that the front-end must replace the prefix

21172 (Freeze_Record_Type): Do not generate the tables associated with
21173 timed and conditional dispatching calls through synchronized
21174 interfaces if compiling under No_Dispatching_Calls restriction.
21175 When compiling for Ada 2005, for a nonabstract
21176 type with a null extension, call Make_Controlling_Function_Wrappers
21177 and insert the wrapper function declarations and bodies (the latter
21178 being appended as freeze actions).
21179 (Predefined_Primitive_Bodies): Do not generate the bodies of the
21180 predefined primitives associated with timed and conditional
21181 dispatching calls through synchronized interfaces if we are
21182 compiling under No_Dispatching_Calls.
21183 (Build_Init_Procedure): Use RTE_Available to check if a run-time
21184 service is available before generating a call.
21185 (Make_Controlling_Function_Wrappers): New procedure.
21186 (Expand_N_Full_Type_Declaration): Create a class-wide master for
21187 access-to-limited-interfaces because they can be used to reference
21188 tasks that implement such limited interface.
21189 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
21190 procedure spec and body of the Offset_To_Top function that is generated
21191 when the parent of a type with discriminants has secondary dispatch
21193 (Init_Secondary_Tags): Handle the case in which the parent of the type
21194 containing secondary dispatch tables has discriminants to generate the
21195 correct arguments to call Set_Offset_To_Top.
21196 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
21198 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
21199 Add Wide_[Wide_]Expanded_Name.
21200 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
21201 the same functionality of Get_Prim_Op_Address but applied to predefined
21202 primitive operations because the pointers to the predefined primitives
21203 are now saved in a separate table.
21204 (Parent_Size): Modified to get access to the separate table of primitive
21205 operations or the parent type.
21206 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
21207 functionality of Set_Prim_Op_Address but applied to predefined primitive
21209 (Set_Signature): New subprogram used to store the signature of a DT.
21210 (Displace): If the Offset_To_Top value is not static then call the
21211 function generated by the expander to get such value; otherwise use
21212 the value stored in the table of interfaces.
21213 (Offset_To_Top): The type of the actual has been changed to Address to
21214 give the correct support to tagged types with discriminants. In this
21215 case this value is stored just immediately after the tag field.
21216 (Set_Offset_To_Top): Two new formals have been added to indicate if the
21217 offset_to_top value is static and hence pass this value to the run-time
21218 to store it in the table of interfaces, or else if this value is dynamic
21219 and then pass to the run-time the address of a function that is
21220 generated by the expander to provide this value for each object of the
21223 * rtsfind.ads (Default_Prin_Op_Count): Removed.
21224 (Default_Prim_Op_Count): New entity

21233 Make_Adjust_Call done for a newly-allocated object.
21235 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
21236 in a subprogram are wrapped in a cleanup block, indicate that the
21237 subprogram contains an inner block with an exception handler.
21238 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
21239 Adjust call is for a newly-allocated object. In that case we must not
21240 assume that the finalization list chain pointers are correct (since they
21241 come from a bit-for-bit copy of the original object's pointers) so if
21242 the attach level would otherwise be zero (no change), we set it to 4
21243 instead to cause the pointers to be reset to null.
21245 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
21246 reset chain pointers to null.
21248 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21250 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
21251 string, and the context requires a loop for the assignment (e.g.
21252 because the left-hand side is packed), generate a unique name for the
21253 temporary that holds the string, to prevent spurious name clashes.
21255 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21256 Javier Miranda <miranda@adacore.com>
21257 Robert Dewar <dewar@adacore.com>
21258 Gary Dismukes <dismukes@adacore.com>
21260 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21261 return unconstrained arrays.
21263 (Expand_Call): An indirect call through an access parameter of a
21264 protected operation is not a protected call.
21265 Add circuit to raise CE in Ada 2005 mode following call
21266 to Raise_Exception.
21267 (Register_DT_Entry): Do nothing if
21268 the run-time does not give support to abstract interfaces.
21269 (Freeze_Subprogram): In case of dispatching operations, do not generate
21270 code to register the operation in the dispatch table if the source
21271 is compiled with No_Dispatching_Calls.
21272 (Register_Predefined_DT_Entry): Generate code that calls the new
21273 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21274 Set_Prim_Op_Address.
21276 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21277 on array assignments if the right-hand side is a function call that has
21278 been inlined. Check is performed on the assignment in the block.
21279 (Process_Bounds): If bounds and range are overloaded, apply preference
21280 rule for root operations to disambiguate, and diagnose true ambiguity.
21281 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21282 a tag-indeterminate right-hand side even when Expander_Active is True.
21283 Needed to ensure that dispatching calls to T'Input are allowed and
21284 get the tag of the target class-wide object.
21286 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21287 an inherited primitive operation that already overrides several
21288 abstract interface primitives. For transitivity, the new entity must
21289 also override all the abstract interface primitives covered by the
21290 inherited overriden primitive.
21291 Emit warning if new entity differs from homograph in same scope only in
21292 that one has an access parameter and the other one has a parameter of
21293 a general access type with the same designated type, at the same
21294 position in the signature.
21295 (Make_Inequality_Operator): Use source locations of parameters and
21296 subtype marks from corresponding equality operator when creating the
21297 tree structure for the implicit declaration of "/=". This does not
21298 change anything in behaviour except that the decoration of the
21299 components of the subtree created for "/=" allows ASIS to get the
21300 string images of the corresponding identifiers.
21301 (Analyze_Return_Statement): Remove '!' in warning message.
21302 (Check_Statement_Sequence): Likewise.
21303 (Analyze_Subprogram_Body): For an access parameter whose designated type
21304 is an incomplete type imported through a limited_with clause, use the
21305 type of the corresponding formal in the body.
21306 (Check_Returns): Implicit return in No_Return procedure now raises
21307 Program_Error with a compile time warning, instead of beging illegal.
21308 (Has_Single_Return): Function returning unconstrained type cannot be
21309 inlined if expression in unique return statement is not an identifier.
21310 (Build_Body_To_Inline): It is possible to inline a function call that
21311 returns an unconstrained type if all return statements in the function
21312 return the same local variable. Subsidiary procedure Has_Single_Return
21313 verifies that the body conforms to this restriction.
21315 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21316 same type, and one of them is of an anonymous access type, convert
21317 the other operand to it, so that this is a valid binary operation for
21319 (Resolve_Type_Conversion): Handle subtypes of protected types and
21320 task types when accessing to the corresponding record type.
21321 (Resolve_Allocator): Add '\' in 2-line warning message.
21322 Remove '!' in warning message.
21323 (Resolve_Call): Add '\' in 2-line warning message.
21324 (Valid_Conversion): Likewise.
21325 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21326 resulting type may be an access type with an implicit dereference.
21327 Obtain the proper component from the designated type.
21328 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21329 given by an expanded name with prefix Standard, when the operands are
21330 of an anonymous access type.
21331 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21332 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21333 prefix of the expression is not of an incomplete type. Allows full
21334 diagnoses of all semantic errors.
21335 (Resolve_Actuals): If the actual is an allocator whose directly
21336 designated type is a class-wide interface we build an anonymous
21337 access type to use it as the type of the allocator. Later, when
21338 the subprogram call is expanded, if the interface has a secondary
21339 dispatch table the expander will add a type conversion to force
21340 the displacement of the pointer.
21341 (Resolve_Call): If a function that returns an unconstrained type is
21342 marked Inlined_Always and inlined, the call will be inlined and does
21343 not require the creation of a transient scope.
21344 (Check_Direct_Boolean_Op): Removed
21345 (Resolve_Comparison_Op): Remove call to above
21346 (Resolve_Equality_Op): Remove call to above
21347 (Resolve_Logical_Op): Inline above, since this is only call.
21348 (Valid_Conversion): Handle properly conversions between arrays of
21349 convertible anonymous access types.
21352 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
21353 the literal in an unchecked conversion, because GCC 4.x needs a static
21354 value for a string bound.
21356 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21357 Hristian Kirtchev <kirtchev@adacore.com>
21359 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
21360 components of the corresponding record, take into account component
21361 definitions that are access definitions.
21362 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
21363 procedure is not considered a dispatching call and will be expanded
21366 2006-02-13 Javier Miranda <miranda@adacore.com>
21368 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
21369 controlling argument of the dispatching call is an abstract interface
21370 class-wide type then we use it directly.
21371 Check No_Dispatching_Calls restriction.
21372 (Default_Prim_Op_Position): Remove the code that looks for the last
21373 entity in the list of aliased subprograms. This code was wrong in
21375 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21376 when the source is compiled with the No_Dispatching_Calls restriction.
21377 (Init_Predefined_Interface_Primitives): No need to inherit primitives
21378 if we are compiling with restriction No_Dispatching_Calls.
21379 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21380 subprograms if we are compiling under No_Dispatching_Calls restriction.
21381 (Make_DT): Generate a dispatch table with a single dummy entry if
21382 we are compiling with the No_Dispatching_Calls restriction. In
21383 addition, in this case we don't generate code that calls to the
21384 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21385 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21386 of this subprogram if compiling with the No_Dispatching_Calls
21388 (Expand_Type_Conversion): Instead of using the actual parameter,
21389 the argument passed as parameter to the conversion function was
21390 erroneously referenced by the expander.
21391 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21392 Set_Predefined_Primitive_Op_Address and Set_Signature.
21393 (Expand_Dispatching_Call): Generate call to
21394 Get_Predefined_Prim_Op_Address for predefined primitives.
21395 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21396 predefined primitives.
21397 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21398 primitives we reserve one dummy entry to ensure that the tag does not
21399 point to some memory that is associated with some other object. In
21400 addition, remove all the old code that generated the assignments
21401 associated with the signature of the dispatch table and replace them
21402 by a call to the new subprogram Set_Signature.
21403 (Set_All_DT_Position): Change the algorithm because now we have a
21404 separate dispatch table associated with predefined primitive operations.
21405 (Expand_Interface_Conversion): In case of non-static offset_to_top
21406 add explicit dereference to get access to the object after the call
21407 to displace the pointer to the object.
21408 (Expand_Interface_Thunk): Modify the generation of the actual used
21409 in the calls to the run-time function Offset_To_Top to fulfil its
21411 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
21413 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21415 * exp_dist.adb (Copy_Specification): For access parameters, copy
21416 Null_Exclusion flag, which will have been set for stream subprograms
21419 2006-02-13 Pascal Obry <obry@adacore.com>
21421 * expect.c (__gnat_expect_portable_execvp): New implementation. The
21422 previous implementation was using the C runtime spawnve routine but
21423 the corresponding wait was using directly the Win32 API. This was
21424 causing some times a lock when waiting for an event using
21425 WaitForSingleObject in __gnat_waitpid. This new implementation uses
21426 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
21427 API fixes this problem.
21429 2006-02-13 Robert Dewar <dewar@adacore.com>
21431 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

21438 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
21439 array reference that is an explicit dereference, mark the converted
21440 (packed) array reference as analyzed to prevent a forthcoming
21441 reanalysis from resetting its type to the original (non-packed) array
21444 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21445 Javier Miranda <miranda@adacore.com>
21446 Eric Botcazou <ebotcazou@adacore.com>
21448 * exp_util.ads, exp_util.adb (Find_Prim_Op,
21449 Is_Predefined_Primitive_Operation): When
21450 searching for the predefined equality operator, verify that operands
21451 have the same type.
21452 (Is_Predefined_Dispatching_Operation): Remove the code that looks
21453 for the last entity in the list of aliased subprograms. This code
21454 was wrong in case of renamings.
21455 (Set_Renamed_Subprogram): New procedure
21456 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
21457 Exp_Type constant computed when entering this subprogram.
21458 (Known_Null): New function
21459 (OK_To_Do_Constant_Replacement): New function
21460 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
21461 (Side_Effect_Free): An attribute reference 'Input is not free of
21462 side effect, unlike other attributes that are functions. (from code
21464 (Remove_Side_Effects): Expressions that involve packed arrays or records
21465 are copied at the point of reference, and therefore must be marked as
21466 renamings of objects.
21467 (Is_Predefined_Dispatching_Operation): Return false if the operation is
21468 not a dispatching operation.
21471 (Remove_Side_Effects): Lift enclosing type conversion nodes for
21472 elementary types in all cases.
21474 2006-02-13 Javier Miranda <miranda@adacore.com>
21476 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
21477 task types when accessing to the corresponding record type.
21478 Remove '!' in warning message.
21480 2006-02-13 Olivier Hainque <hainque@adacore.com>
21482 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
21483 to avoid useless and space inefficient overalignments on targets where
21484 Max_Alignment is larger than 16.
21486 2006-02-13 Pascal Obry <obry@adacore.com>
21488 * g-catiio.adb (Sec_Number): New type used to compute the number of
21489 seconds since 1-1-1970.
21490 (Image) [Natural]: The parameter was an Integer, as we can't deal with
21491 negative numbers (years, months...) it is better to have a Natural here.
21493 (Image) [Number]: Change parameter from Long_Integer to Number.
21494 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
21495 overflow for dates past year 2038.
21497 2006-02-13 Matthew Heaney <heaney@adacore.com>
21499 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
21502 2006-02-13 Arnaud Charlet <charlet@adacore.com>
21504 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
21506 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
21507 finalization can occur normally.
21509 2006-02-13 Vincent Celier <celier@adacore.com>
21511 * gnatcmd.adb (Rules_Switches): New table
21512 (Add_To_Rules_Switches): New procedure
21513 (GNATCmd): For command CHECK, put all options following "-rules" in the
21514 Rules_Switches table. Append these -rules switches after the -cargs
21517 2006-02-13 Robert Dewar <dewar@adacore.com>
21519 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
21520 These two cases were generating incorrect output, and if this unit
21521 was built with checks on, generated a discriminant mismatch constraint
21524 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21525 Robert Dewar <dewar@adacore.com>
21527 * lib-xref.adb (Get_Type_Reference): For a private type whose full
21528 view is an array type, indicate the component type as well, for
21529 navigation purposes.
21530 (Generate_Reference): Don't consider array ref on LHS to be a case
21531 of violating pragma Unreferenced.
21532 Do not give Ada 2005 warning except on real reference.
21534 2006-02-13 Vincent Celier <celier@adacore.com>
21536 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
21537 main source, add switch -mdebug-main=_ada_ so that the executable can
21538 be debugged by the standard VMS debugger.
21539 (Gnatmake): Set No_Main_Subprogram to True when there is no main
21540 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
21541 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
21542 of the last source, as the binding and linking phases are never
21544 Set all executable obsolete when rebuilding a library.
21546 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
21549 2006-02-13 Javier Miranda <miranda@adacore.com>
21552 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
21553 code to improve the error message reported when the program has
21554 declarations of abstract interface types and it is not compiled with
21555 the -gnat05 switch.
21556 (P_Access_Definition): Reorganize the code to improve the error
21557 message reported when the new Ada 2005 syntax for anonymous
21558 access types is used and the program is not compiled with the
21561 2006-02-13 Robert Dewar <dewar@adacore.com>
21563 * par-ch6.adb, style.ads, styleg.adb, styleg.ads, stylesw.adb,

21567 2006-02-13 Javier Miranda <miranda@adacore.com>
21569 * par-endh.adb (Explicit_Start_Label): Add code to protect the parser
21570 against source containing syntax errors.
21572 2006-02-13 Vincent Celier <celier@adacore.com>
21574 * prj.adb (Reset): Initialize the first element of table Namings with
21575 the standard naming data.
21577 2006-02-13 Vincent Celier <celier@adacore.com>
21579 * prj.ads (Error_Warning): New enumeration type
21581 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
21582 unknown, use the location of the project to report the error.
21583 (When_No_Sources): New global variable
21584 (Report_No_Ada_Sources): New procedure
21585 (Check): New parameter When_No_Sources. Set value of global variable
21587 (Find_Sources): Call Report_No_Ada_Sources when appropriate
21588 (Get_Sources_From_File): Ditto
21589 (Warn_If_Not_Sources): Better warning messages indicating the unit name
21592 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
21593 Call Prj.Proc.Process with parameter When_No_Sources.
21595 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
21596 Call Recursive_Check with parameter When_No_Sources.
21597 (Recursive_Check): New parameter When_No_Sources. Call itself and
21598 Prj.Nmsc.Check with parameter When_No_Sources.
21599 (Process): New parameter When_No_Sources. Call Check with parameter
21601 (Copy_Package_Declarations): New procedure to copy renamed parameters
21602 and setting the location of the declared attributes to the location
21603 of the renamed package.

21609 * prj-makr.adb (Make): Preserve the comments from the original project
21611 When removing nodes (attributes Source_Dirs, Source_Files,
21612 Source_List_File and package Naming), save the comments and attach the
21613 saved comments to the newly created nodes.
21614 Do not add a with clause for the naming package if one already exists.

21622 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
21623 aliased entities to look for the overriden abstract interface
21625 (Is_Interface_Subprogram): Complete documentation.
21626 (Check_Dispatching_Operation): Do not generate code to register the
21627 operation in the dispatch table if the source is compiled with
21628 restriction No_Dispatching_Calls.
21629 (Override_Dispatching_Operation): Check for illegal attempt to override
21630 No_Return procedure with procedure that is not No_Return
21631 (Check_Dispatching_Call): Suppress the check for an abstract operation
21632 when the original node of an actual is a tag-indeterminate attribute
21633 call, since the attribute, which must be 'Input, can never be abstract.
21634 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
21635 call to the Input attribute (even when rewritten).
21636 (Propagate_Tag): Augment comment to indicate the possibility of a call
21637 to an Input attribute.
21639 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
21640 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
21642 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
21643 No_Wide_Characters is no longer partition-wide
21644 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
21647 2006-02-13 Douglas Rupp <rupp@adacore.com>
21649 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
21651 2006-02-13 Javier Miranda <miranda@adacore.com>
21653 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
21654 handles default-initialized components to keep separate the management
21655 of this feature but also avoid the unrequired resolution and
21656 expansion of components that do not have partially initialized
21658 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
21659 (Check_Bounds): Likewise.
21660 (Check_Length): Likewise.
21662 2006-02-13 Javier Miranda <miranda@adacore.com>
21663 Ed Schonberg <schonberg@adacore.com>
21665 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21666 abstract interface type call analyze_and_resolve to expand the type
21667 conversion into the corresponding displacement of the
21668 reference to the base of the object.
21669 (Eval_Attribute, case Width): For systems where IEEE extended precision
21670 is supported, the maximum exponent occupies 4 decimal digits.
21671 (Accessibility_Message): Add '\' in 2-line warning message.
21672 (Resolve_Attribute): Likewise.
21673 (case Attribute_Access): Significantly revise checks
21674 for illegal access-to-subprogram Access attributes to properly enforce
21675 the rules of 3.10.2(32/2).
21676 Diagnose use of current instance with an illegal attribute.
21678 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21680 (Enclosing_Generic_Unit): New function to return a node's innermost
21681 enclosing generic declaration node.
21682 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21683 (Type_Access_Level): The accessibility level of anonymous acccess types
21684 associated with discriminants is that of the current instance of the
21685 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21686 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21687 (Kill_Current_Values_For_Entity): New function
21688 (Enter_Name): Change formal type to Entity_Id
21690 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21691 Ed Schonberg <schonberg@adacore.com>
21692 Gary Dismukes <dismukes@adacore.com>
21694 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21695 Analyze_Compilation_Unit.
21696 Detect and warn on redundant with clauses detected in a package spec
21697 and/or body when -gnatwr is used.

21699 (Install_Context_Items): Don't analyze config pragmas here
21700 (Install_Limited_Withed_Unit): Set limited entity of package in
21701 with_clause so that cross-reference information or warning messages on
21702 unused packages can be properly generated
21703 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21704 has Error_Posted set. Prevent infinite loops in illegal programs.
21705 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21706 to the point of the error test requiring the current unit to be private.
21707 This ensures that private with clauses are not exempted from the basic
21708 checking for being a descendant of the same library unit parent as a
21709 withed private descendant unit.
21710 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21711 handle private with clauses properly, as well as to account for cases
21712 where the withed unit is a public descendant of a private ancestor
21713 (in which case the current unit must be a descendant of the private
21714 ancestor's parent). The spec comments were updated accordingly. Also,
21715 the old error message in this subprogram was replaced with error
21716 messages that mirror the errors tested and reported by
21717 Check_Private_Child_Unit.
21718 Parameter and variable names improved for readability.
21719 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21720 private as the precondition for calling
21721 Check_Private_Limited_Withed_Unit since that subprogram has been
21722 revised to test public units as well as private units.

21727 Javier Miranda <miranda@adacore.com>
21729 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21730 that Scope_Stack.First = 1.
21731 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21732 were not always properly handled previously.
21733 (Formal_Entity): Complete rewrite, to handle properly some complex case
21734 with multiple levels of parametrization by formal packages.
21735 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21736 to the corresponding derived type declaration for proper semantics.
21738 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21739 (Check_Component): Enforce restriction on components of
21740 unchecked_unions: a component in a variant cannot contain tasks or
21742 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21744 Add pragma Ada_2005 (synonym for Ada_05)
21745 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21746 were not always properly handled previously.
21747 Document that pragma Propagate_Exceptions has no effect
21748 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21749 (Set_Convention_From_Pragma): Check that if a convention is
21750 specified for a dispatching operation, then it must be
21751 consistent with the existing convention for the operation.
21752 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21753 longer required to specify an vtable-ptr component in the record. For
21754 compatibility reasons we leave the support for the previous definition.
21755 (Analyze_Pragma, case No_Return): Allow multiple arguments
21757 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21758 non-overrideen inherited operation with a controlling result as
21759 illegal only its implicit declaration comes from the derived type
21760 declaration of its result's type.
21761 (Check_Possible_Deferred_Completion): Relocate the object definition
21762 node of the subtype indication of a deferred constant completion rather
21763 than directly analyzing it. The analysis of the generated subtype will
21764 correctly decorate the GNAT tree.
21765 (Record_Type_Declaration): Check whether this is a declaration for a
21766 limited derived record before analyzing components.
21767 (Analyze_Component_Declaration): Diagnose record types not explicitly
21768 declared limited when a component has a limited type.
21769 (Build_Derived_Record_Type): Code reorganization to check if some of
21770 the inherited subprograms of a tagged type cover interface primitives.
21771 This check was missing in case of a full-type associated with a private
21773 (Constant_Redeclaration): Check that the subtypes of the partial and the
21774 full view of a constrained deferred constant statically match.
21775 (Mentions_T): A reference to the current type in an anonymous access
21776 component declaration must be an entity name.
21777 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21778 class_wide type to refer to full type, not to the incomplete one.
21779 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21780 available. Required to give support to the certified run-time.
21781 (Analyze_Component_Declaration): In case of anonymous access components
21782 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21783 (Process_Discriminants): For an access discriminant, use the
21784 discriminant specification as the associated_node_for_itype, to
21785 simplify accessibility checks.

21788 Javier Miranda <miranda@adacore.com>
21790 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21791 abstract interpretations on an operator, remove interpretations that
21792 yield Address or a type derived from it, if one of the operands is an
21794 (Try_Object_Operation.Try_Primitive_Operation,
21795 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21796 location when creating the new reference to a primitive or class-wide
21797 operation as a part of rewriting a subprogram call.
21798 (Try_Primitive_Operations): If context requires a function, collect all
21799 interpretations after the first match, because there may be primitive
21800 operations of the same type with the same profile and different return
21801 types. From code reading.
21802 (Try_Primitive_Operation): Use the node kind to choose the proper
21803 operation when a function and a procedure have the same parameter
21805 (Complete_Object_Operation): If formal is an access parameter and prefix
21806 is an object, rewrite as an Access reference, to match signature of
21807 primitive operation.
21808 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21809 by an expanded name with prefix Standard, when the operands are of an
21810 anonymous access type.
21811 (Remove_Abstract_Operations): If the operation is abstract because it is
21812 inherited by a user-defined type derived from Address, remove it as
21813 well from the set of candidate interpretations of an overloaded node.
21814 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21817 2006-02-13 Bob Duff <duff@adacore.com>
21819 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21820 redundant use clauses.
21821 In particular, if the scope of two use clauses overlaps, but one is not
21822 entirely included in the other, we should not warn. This can happen
21823 with nested packages.
21824 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21825 reported errors. The bug was reported when the compiler was built
21826 with assertions enabled.
21827 (Find_Type): If the node is a 'Class reference and the prefix is a
21828 synchronized type without a corresponding record, return the type
21831 2006-02-13 Javier Miranda <miranda@adacore.com>
21833 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21834 if this is the full-declaration associated with a private declaration
21835 that implement interfaces, then the private type declaration must be
21837 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21838 as aliased. The use of the 'access attribute is not available for such
21839 object (for this purpose the object should be explicitly marked as
21840 aliased, but being an anonymous type this is not possible).
21842 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21843 Robert Dewar <dewar@adacore.com>
21845 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21846 compilation unit is an elaboration scope.
21847 (Add_Task_Proc): Add '\' in 2-line warning message.
21848 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21850 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21851 Javier Miranda <miranda@adacore.com>
21853 * sem_type.adb (Write_Overloads): Improve display of candidate
21855 (Add_One_Interp): Do not add to the list of interpretations aliased
21856 entities corresponding with an abstract interface type that is an
21857 immediate ancestor of a tagged type; otherwise we have a dummy
21858 conflict between this entity and the aliased entity.
21859 (Disambiguate): The predefined equality on universal_access is not
21860 usable if there is a user-defined equality with the proper signature,
21861 declared in the same declarative part as the designated type.
21862 (Find_Unique_Type): The universal_access equality operator defined under
21863 AI-230 does not cover pool specific access types.
21864 (Covers): If one of the types is a generic actual subtype, check whether
21865 it matches the partial view of the other type.
21867 2006-02-13 Thomas Quinot <quinot@adacore.com>
21869 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21870 line. This is necessary to allow In_Extended_Main_Unit to provide
21871 correct results for itypes while writing out expanded source.
21872 (Close_File): No need to update the source_index_table here since it's
21873 now done for each line.
21875 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21876 Robert Dewar <dewar@adacore.com>
21878 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21879 preserve the source unit where the itype is declared, and prevent a
21881 (Note_Implicit_Run_Time_Call): New procedure
21882 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21885 * sprint.ads: Document use of $ for implicit run time routine call
21887 2006-02-13 Quentin Ochem <ochem@adacore.com>
21889 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21892 2006-02-13 Bob Duff <duff@adacore.com>
21894 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21895 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21896 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21897 raise Constraint_Error.
21899 * s-vallli.adb (Scan_Long_Long_Integer): Call
21900 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21901 do not scan leading blanks and sign twice.
21902 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21903 raise Constraint_Error.
21905 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21906 Scan_Long_Long_Unsigned): Split out most of the processing from
21907 Scan_Long_Long_Unsigned out into
21908 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21909 This prevents scanning leading blanks and sign twice.
21910 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21913 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21914 out most of the processing from Scan_Unsigned out into
21915 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21916 This prevents scanning leading blanks and sign twice.
21918 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21919 use with Modular'Value attribute.
21920 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
21923 2006-02-13 Robert Dewar <dewar@adacore.com>
21925 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
21927 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

22118 * a-taster.ads, a-taster.adb: New files.
22120 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
22121 link to the version that does nothing. This way the task termination
22122 routine is not executed twice for the environment task when finishing
22123 because of an unhandled exception.
22125 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
22126 handler because of an unhandled exception.
22128 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
22129 System.Tasking.Utilities instead of that in System.Tasking.Stages.
22131 * s-finimp.adb (initialization code): Modify the soft link for the
22132 finalization of the global list instead of Adafinal.
22134 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
22135 non-tasking version of the soft link for task termination. We do
22136 nothing since if we are using the non-tasking version it
22137 means that the task termination functionality is not used.
22138 (Null_Finalize_Global_List): Add this null version for the procedure
22139 in charge of finalizing the global list for controlled objects.
22140 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
22141 instead for handling run-time termination in a more flexible way.
22142 (Adafinal_NT): This new procedure will take care of finalizing the
22143 global list for controlled objects if needed, but no tasking
22146 * s-tarest.adb (Task_Lock): Do not try to lock again the
22147 Global_Task_Lock if we already own it. Otherwise, we get blocked in
22148 some run-time operations.
22149 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
22150 until all nested locks have been released.
22151 (Task_Wrapper): Call the fall-back task termination handler. It
22152 applies to all tasks but the environment task.
22153 (Finalize_Global_Tasks): Add the call for the task termination
22154 procedure for the environment task.
22155 (Task_Wrapper): suppress warnings around declaration of
22156 Secondary_Stack_Address.
22158 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
22159 moved to the Common_ATCB record.
22160 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
22161 Common_ATCB record.
22162 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
22163 Common_ATCB record.
22165 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
22166 Fall_Back_Handler, and Specific_Handler.
22168 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
22169 defined in Ada.Task_Termination, to avoid circular dependencies.
22170 (Termination_Handler): Redefine this type here, alredy defined in
22171 Ada.Task_Termination, for avoiding circular dependencies.
22172 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
22173 for storing task termination handlers. In addition,
22174 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
22175 Common_ATCB because it is used by both the regular and the restricted
22177 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
22178 Common_ATCB because it is used by both the regular and the restricted
22180 (Common_ATCB): Added a dynamic task analyzer field.
22182 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
22183 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
22184 (Task_Wrapper): Call the task termination handler. It applies to all
22185 tasks but the environment task.
22186 (Finalize_Global_Tasks): Call the task termination procedure for the
22187 environment task. The call to Finalize_Global_List is now performed
22188 using the soft links mechanism.
22189 (Task_Wrapper): added dynamic stack analysis.
22191 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
22192 potentially blocking operations has been moved from
22193 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
22194 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
22195 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
22196 this run-time check.
22198 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
22199 of task termination procedure.
22200 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
22201 link for the task termination procedure.
22203 * bindusg.adb: (Bindusg): Added documentation for -u option.

22217 (Standart_Output): new subprogram
22218 (Set_Output): new subprogram
22219 (Put): now uses the value of Current_Out to know if the output has to be
22220 send to stderr or stdout.
22222 * s-stausa.ads: Complete implementation.
22224 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
22226 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
22227 list of Ada 05 files.
22228 (GNAT Library Units): Add AltiVec files.

22237 file_name is empty.
22239 2005-12-09 Javier Miranda <miranda@adacore.com>
22240 Hristian Kirtchev <kirtchev@adacore.com>
22242 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
22243 to the specification because the frontend generates code that uses this
22245 (Set_Interface_Table): Add missing assertion.
22246 Update documentation describing the run-time structure.
22247 (Displace): New subprogram that displaces the pointer to the object
22248 to reference one of its secondary dispatch tables.
22249 (IW_Membership): Modified to use the new table of interfaces.
22250 (Inherit_TSD): Modified to use the new table of interfaces.
22251 (Register_Interface_Tag): Use the additional formal to fill the
22252 contents of the new table of interfaces.
22253 (Set_Interface_Table): New subprogram that stores in the TSD the
22254 pointer to the table of interfaces.
22255 (Set_Offset_To_Top): Use the additional formal to save copy of
22256 the offset value in the table of interfaces.
22257 Update structure of GNAT Primary and Secondary dispatch table diagram.
22258 Add comment section on GNAT dispatch table prologue.
22259 (Offset_To_Signature): Update the constant value of the Signature field.
22260 (Dispatch_Table): Update comment on hidden fields in the prologue.

22268 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
22269 in all the calls to Expand_Interface_Thunk. Instead of referencing the
22270 record component containing the tag of the secondary dispatch table we
22271 have to use the Offset_To_Top run-time function to get this information;
22272 otherwise if the pointer to the base of the object has been displace
22273 we get a wrong value if we use the 'position attribute.
22275 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
22276 all the calls to Expand_Interface_Thunk.
22277 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

22280 ensure that the interfaces implemented by the ancestors are placed
22281 at the header of the generated list.
22282 (Expand_Interface_Conversion): Handle the case in which the displacement
22283 associated with the interface conversion is not statically known. In

22311 RE_TK_Tagged, RE_TK_Task.
22313 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22314 Init_Secondary_Tags_Internal to allow its use with interface types and
22315 also to generate the code for the new additional actual required
22316 by Set_Offset_To_Top.
22317 (Build_Init_Statements): In case of components associated with abstract
22318 interface types there is no need to generate a call to its IP.
22319 (Freeze_Record_Type): Generate Select Specific Data tables only for

22330 properly protected objects and attach handler in the case of the
22331 restricted profile.

22345 pointer initialization values. Make a SAVE_EXPR instead. Add comments
22346 about the use and expansion of SAVE_EXPRs in the various possible
22347 renaming handling cases.
22348 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
22349 abusing DECL_FCONTEXT.

22451 2005-12-09 Robert Dewar <dewar@adacore.com>
22453 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

22468 component associated with the secondary table of an abstract interface
22469 type, return the entity associated with such abstract interface type.
22470 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
22471 base type to create anonymous subtype, because entity may be a locally
22472 declared subtype or generic actual.
22473 (Find_Interface): New subprogram that given a tagged type and one of its
22474 component associated with the secondary table of an abstract interface
22475 type, return the entity associated with such abstract interface type.

22517 legal within a protected type that implements an interface.
22518 (Collect_Interfaces): Do not add to the list the interfaces that
22519 are implemented by the ancestors.
22520 (Derived_Type_Declaration): If the parent of the full-view is an
22521 interface perform a transformation of the tree to ensure that it has
22522 the same parent than the partial-view. This simplifies the job of the
22523 expander in order to generate the correct object layout, and it is
22524 needed because the list of interfaces of the full-view can be given in
22526 (Process_Full_View): The parent of the full-view does not need to be
22527 a descendant of the parent of the partial view if both parents are
22529 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22530 "limited" the parent must be a limited type.

22544 (Process_Full_View): Improve the check for the "no hidden interface"
22545 rule as defined by AI-396.
22547 2005-12-09 Robert Dewar <dewar@adacore.com>

22604 available user-specified stream attributes on limited parameters to
22605 also test the type directly rather than only its underlying type (for
22606 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22607 attributes are visible at the point of the subprogram declaration.
22608 For Ada 2005, the error message is modified to indicate that the
22609 type's stream attributes must be visible (again, only for -gnat05).

22776 Roger Sayle <roger@eyesopen.com>
22779 * misc.c (internal_error_function): Don't use vsprintf to format

22791 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
22792 a temporary if taking the address of something that is neither
22793 reference, declaration, or constant, since the gimplifier
22794 can't handle that case.

22867 TARGET, as it has the form of a math expression, and some components
22868 may be platform-defined macros.
22869 For VxWorks, generate the OK and ERROR values.
22870 New constants giving the sizes of the components of C struct timeval.

22882 deal with different cases of static and dynamic elaboration checks (all
22883 checks does not count in the first case, but does in the second).

22889 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22890 elementary types using the operator in standard. It is cleaner not to
22891 modify the programmers intent, especially in the case of floating-point.
22892 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22893 it did not matter because we always rewrote a/=b to not(a=b).
22894 (Expand_Allocator_Expression): For an allocator expression whose nominal
22895 subtype is an unconstrained packed type, convert the expression to its
22896 actual constrained subtype.
22897 Implement warning for <= or >= where < or > not possible
22898 Fix to Vax_Float tests (too early in many routines, causing premature
22899 Vax_Float expansions.
22901 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
22902 to be used with packages and generic packages as well as with

22905 of pragma Suppress (All_Checks)
22906 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22907 a string literal for precise control over warnings.

22917 Allow optional = after -gnatm
22918 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22919 longer sets Elaboration_Checks.
22920 Code to set warning mode moved to Sem_Warn
22921 so that it can be shared by pragma processing.
22923 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22926 * s-taprop-solaris.adb:
22927 Change some <= to =, to avoid new warning

22931 Fix obvious typo (Total_Errors_Detected <= 0 should be = 0)
22933 2005-11-14 Robert Dewar <dewar@adacore.com>
22935 * exp_vfpt.adb: Handle /= case
22936 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
22937 so that we do not get duplicate scaling for fixed point conversions.
22939 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
22941 2005-11-14 Matthew Gingell <gingell@adacore.com>
22943 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
22944 Increase default priority on Lynx from 15 to 17, and meet the Ada
22945 requirement that Default_Priority be ((Priority'First +
22946 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

23043 from a fat or thin pointer type and a constrained object type.
23044 (annotate_value): Handle BIT_AND_EXPR.
23045 (annotate_rep): Don't restrict the back annotation of inherited
23046 components to the type_annotate_only case.

23048 we are not defining the type.
23049 <E_Record_Type>: Likewise.
23050 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
23051 to get advantage of the new maybe_stabilize_reference interface, to
23052 ensure that what we reference is indeed stabilized instead of relying
23053 on assumptions on what the stabilizer does.
23054 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
23055 type imported through a limited_with clause, use its non-limited view.
23056 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
23058 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
23059 of #if sections + explicit comparisons of convention identifiers.

23061 before early-returning for certain types when code generation is
23063 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

23065 that we are not defining.
23066 (elaborate_expression_1): Do not create constants when creating
23067 variables needed by the debug info: the dwarf2 writer considers that
23068 CONST_DECLs is used only to represent enumeration constants, and emits
23070 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
23071 object with an address clause into an indirect reference, drop the
23072 initializing expression.
23074 (STACK_CHECK_BUILTIN): Delete.
23075 (STACK_CHECK_PROBE_INTERVAL): Likewise.

23083 if there is an actual subtype provided by the front-end, use that
23084 subtype to build an actual type with bounds template.
23085 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
23086 is provided by the front-end, use that subtype to compute the size of
23087 the deallocated object.

23089 check for a potential violation of a No_Elaboration_Code restriction.
23090 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
23091 with extra arguments to control whether to recurse through non-values

23094 maybe_stabilize, for common uses without restriction on lvalues and
23095 without need to check for the success indication.
23096 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
23097 pass false instead of 0 as the FORCE argument which is a bool.
23098 (Identifier_to_gnu): Remove checks ensuring that an renamed object
23099 attached to a renaming pointer has been properly stabilized, as no such
23100 object is attached otherwise.
23101 (call_to_gnu): Invoke create_var_decl to create the temporary when the
23102 function uses the "target pointer" return mechanism.
23103 Reinstate conversion of the actual to the type of the formal
23104 parameter before any other specific treatment based on the passing
23105 mechanism. This turns out to be necessary in order for PLACEHOLDER
23106 substitution to work properly when the latter type is unconstrained.

23110 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

23112 and to let the caller know if the stabilization has succeeded.
23114 * utils2.c (gnat_build_constructor): Only sort the fields for possible
23115 static output of record constructor if all the components are constant.
23116 (gnat_build_constructor): For a record type, sort the list of field
23117 initializers in increasing bit position order.
23118 Factor common code to build a storage type for an unconstrained object
23119 from a fat or thin pointer type and a constrained object type.
23120 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
23121 types variants, and process special cases of VIEW_CONVERT expressions
23122 as their NOP_EXPR counterpart to ensure we get to the
23123 CORRESPONDING_VARs associated with CONST_DECls.
23124 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
23125 on the right-hand side.

23130 are converting back to its original type.
23131 (convert) <JM input>: Fallthrough regular conversion code instead of
23132 extracting the object if converting to a type variant.
23133 (create_var_decl): When a variable has an initializer requiring code
23134 generation and we are at the top level, check for a potential violation
23135 of a No_Elaboration_Code restriction.
23136 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
23137 SIZE and SIZE_UNIT which we need for later back-annotations.

23139 <VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
23140 is an unchecked union.

23142 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
23143 main variant, just replace the VIEW_CONVERT_EXPR.

23279 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
23280 for task component, in the case of a limited aggregate. The enclosed
23281 object declaration will create it earlier. Otherwise, in the case of a
23282 nested aggregate, the object may appear in the wrong scope.
23283 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
23284 (Gen_Assign): If the component being assigned is an array type and the
23285 expression is itself an aggregate, wrap the assignment in a block to
23286 force finalization actions on the temporary created for each row of the
23288 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
23289 structures are initialized after all discriminants are set so that
23290 they can be accessed even when their offset is dynamic.

23318 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
23319 and related): For a prefix that is an explicit dereference of an

23321 with an actual subtype so GIGI can make a correct size computation.
23322 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
23323 'Unrestricted_Access, if the designated type is an interface we
23324 add a type conversion to force the displacement of the pointer
23325 to the secondary dispatch table.
23326 Use Universal_Real instead of Long_Long_Float when we need a high
23327 precision float type for the generated code (prevents gratuitous
23328 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23329 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
23330 'Terminated for task interface class-wide objects. Generate a call to
23331 the predefined dispatching routine used to retrieve the _task_id from
23332 a task corresponding record.

23356 (Expand_N_If_Statement): When killing a dead then-branch in an
23357 if-statement that has elsif_parts, recompute the Current_Value node
23358 for any entity whose value is known from the condition of the first
23360 (Expand_N_Return_Statement): When returning a mutable record, convert
23361 the return value into its actual subtype in order to help the backend
23362 to return the actual size instead of the maximum. This is another
23363 aftermath of not returning mutable records on the sec-stack anymore.
23365 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
23366 handling of error msg for suspicious reverse range iteration.
23367 (Check_Possible_Current_Value_Condition): Move declaration from body to

23388 (Send_Signal): Release the process handle.
23390 2005-11-14 Robert Dewar <dewar@adacore.com>
23392 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
23393 need a high precision float type for the generated code (prevents
23394 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)

23412 attribute of the N_Free_Statement.
23413 Generate itype for classwide designated object in both cases of
23414 user-specified storage pool: specific and class-wide, not only in the
23416 Raise CE when trying to set a not null access type object to null.
23417 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
23418 an explicit loop, because freeze nodes make its position variable.

23641 unit, to prevent scope stack errors.
23642 (Save_References): If the node is an aggregate that is an actual in a
23643 call, rewrite as a qualified expression to preserve some type
23644 information, to resolve possible ambiguities in the instance.
23645 (Instance_Parent_Unit): New global variable to record the ultimate
23646 parent unit associated with a generic child unit instance (associated

23655 scope against package Standard. Add comments and a ??? comment.
23656 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
23657 on a child instance parent to test that the parent equals

23677 full view to construct the full declaration of the derived type.
23678 (Build_Derived_Record_Type): Relax the condition that controls the
23679 execution of the check that verifies that the partial view and

23688 view is a transitive derivation of the ancestor of the partial view.
23689 (Process_Full_View): Rename local subprogram Find_Interface_In_
23690 Descendant to Find_Ancestor_Interface to leave the code more clear.
23691 Remove wrong code that avoids the generation of an error message
23692 when the immediate ancestor of the partial view is an interface.
23693 In addition some minor reorganization of the code has been done to
23694 leave it more clear.
23695 (Analyze_Type_Declaration): If type has previous incomplete tagged
23696 partial view, inherit properly its primitive operations.

23708 (Collect_Interfaces): For private extensions and for derived task types
23709 and derived protected types, the parent may be an interface that must
23710 be included in the interface list.
23711 (Access_Definition): If the designated type is an interface that may
23712 contain tasks, create Master_Id for it before analyzing the expression
23713 of the declaration, which may be an allocator.
23714 (Record_Type_Declaration): Set properly the interface kind, for use
23715 in allocators, the creation of master id's for task interfaces, etc.

23724 subprogram declaration.
23725 Change name Is_Package to Is_Package_Or_Generic_Package
23726 (Process_Formals): A non null qualifier on a non null named access
23727 type is not an error, and is a warning only if Redundant_Constructs

23731 Ed Schonberg <schonberg@adacore.com>
23733 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
23734 nested within Analyze_Package_Specification to install the private

23736 package instance of a generic child package.
23737 (Analyze_Package_Specification): When entering a private part of a
23738 package associated with a generic instance or formal package, the
23739 private declarations of the parent must be installed (by calling new
23740 procedure Install_Parent_Private_Declarations).
23741 Change name Is_Package to Is_Package_Or_Generic_Package
23742 (Preserve_Full_Attributes): For a synchronized type, the corresponding

23748 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
23749 not try to rewrite a renamed stream attribute, because the operations
23750 on the type may not have been generated.
23751 Handle properly a renaming_as_body generated for a stream operation
23752 whose default is abstract because the object type itself is abstract.
23753 (Find_Type): If the type is incomplete and appears as the prefix of a
23754 'Class reference, it is tagged, and its list of primitive operations
23755 must be initialized properly.
23756 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23757 private declaration of a parent unit, prior to compiling the private
23758 part of a child unit, find on the scope stack the proper parent entity
23759 on which to link the use clause.
23760 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23762 (Analyze_Object_Renaming): An attribute reference is not a legal object
23763 if it is not a function call.

23783 remove address operations.
23784 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
23785 statement to inhibit warning.
23786 (Resolve_Unary_Op): Do not produce a warning when
23787 processing an expression of the form -(A mod B)
23788 Use Universal_Real instead of Long_Long_Float when we need a high
23789 precision float type for the generated code (prevents gratuitous
23790 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23791 (Resolve_Concatenation_Arg): Improve error message when argument is an
23792 ambiguous call to a function that returns an array.
23793 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
23794 there is an implicit operator in the given scope if we are within an
23795 instance: legality check has been performed on the generic.
23796 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
23797 after resolving operand, to avoid false warnings on overloaded calls.

23800 Javier Miranda <miranda@adacore.com>
23803 * sem_type.adb (Covers): In an inlined body, a composite type matches
23804 a private type whose full view is a composite type.
23805 (Interface_Present_In_Ancestor): Protect the frontend against
23806 previously detected errors to ensure that its compilation
23807 with assertions enabled gives the same output that its
23808 compilation without assertions.
23809 (Interface_Present_In_Ancestor): Add support for private types.
23810 Change name In_Actual to In_Generic_Actual (clean up)
23811 (Disambiguate): New predicate In_Actual, to recognize expressions that
23812 appear in the renaming declaration generated for generic actuals, and
23813 which must be resolved in the outer context.

23827 for a parameterless procedure.
23828 (Enter_Name): Recognize renaming declarations created for private
23829 component of a protected type within protected operations, so that
23830 the source name of the component can be used in the debugger.

24519 code generated by the expander.
24520 (Expand_Interface_Conversion): If the actual is an access type then
24521 build an internal function to handle the displacement. If the actual
24522 is null this function returns null because no displacement is
24523 required; otherwise performs a type conversion that will be
24524 expanded in the code that returns the value of the displaced actual.
24525 (Expand_Interface_Actuals): Avoid the generation of unnecessary type

24540 entities from the limited-view.
24542 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
24543 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,

24573 package can be used for VxWorks 5.x and 6.x
24574 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
24575 differences between VxWorks 5.x and 6.x

24632 This change also makes gen-soccon self-contained (removing dependencies
24633 upon GCC internal headers).
24635 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
24637 (To_Inet_Addr): Now a procedure instead of a function, more efficient.

24771 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24772 from object notation, the original node is unanalyzed and carries no
24773 semantic information, so that accessiblity checks must be performed on
24774 the type of the actual itself.

24787 load comes from a Limited_With_Clause.
24789 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24790 whether a potential circularity is harmless, because it includes units
24791 loaded through a limited_with clause. Extends previous treatment which
24792 did not handle properly arbitrary combinations of limited and
24793 non-limited clauses.

24825 (Close): Deallocate any existing filter for the concerned connection
24827 2005-09-01 Laurent Pautet <pautet@adacore.com>
24829 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24830 position set is provided, we compute one in order to reduce the maximum
24831 length of the keys. This computation first selects a character
24832 position between 1 and the minimum length of the keys in order to
24833 avoid reducing one of the keys to an empty string.
24834 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24835 does not converge. The initialization procedure now comes with a
24836 maximum number of iterations such that when exceeded, an exception is
24837 raised in Compute. The user can initialize this ratio to another value
24839 Reformating and updated headers.
24841 2005-09-01 Javier Miranda <miranda@adacore.com>
24843 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24844 that given an entity T creates and returns an Itype that duplicates the
24845 contents of T. The returned Itype has the null-exclusion
24846 attribute set to True, and its Etype attribute references T
24847 to keep the association between the two entities.
24848 Update copyright notice
24850 * sem_aggr.adb (Check_Can_Never_Be_Null,
24851 Aggregate_Constraint_Checks, Resolve_Aggregate,

24871 (P_Access_Type_Definition): Add parsing for an anonymous access result
24872 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24873 instead of Set_Subtype_Mark.

24882 (Set_Result_Definition): New procedure for N_Function_Specifications.
24883 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24884 and N_Function_Specification.
24886 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24887 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
24888 Add support for LIMITED NEW for Ada 2005 AI-419
24889 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24890 syntax for anonymous access results.

24900 Result_Definition for cases of N_Access_Function_Definition and
24901 N_Function_Specification.
24902 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
24904 2005-09-01 Vincent Celier <celier@adacore.com>
24906 * lib-writ.adb: Update Copyright notice
24907 (Write_With_Lines): On platforms where file names are case-insensitive,
24908 record the file names in lower case.
24909 (Write_ALI): For D lines, on platforms where file names are
24910 case-insensitive, record the file names in lower case.

24929 including those that are inherited.
24931 2005-09-01 Robert Dewar <dewar@adacore.com>
24933 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
24935 * par-prag.adb: Implement new pragma Debug_Policy
24937 * sem_prag.adb Implement new pragma Debug_Policy
24938 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
24939 Component_Size attribute specification. Give warning for ignored pragma
24942 * snames.h, snames.ads, snames.adb: Introduce entries in
24943 Preset_Names for Name_Disp_Asynchronous_Select,
24944 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24945 Name_Disp_Timed_Select.
24946 New pragma Debug_Policy
24948 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24950 Switch -gnata also sets Debug_Pragmas_Enabled
24952 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24953 handle an explicit -gnata when compiling predefined files.
24955 2005-09-01 Vincent Celier <celier@adacore.com>
24957 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24958 directories of projects that have no Ada sources.
24960 2005-09-01 Robert Dewar <dewar@adacore.com>
24962 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24963 (makes a difference for wide characters)
24965 * widechar.adb, widechar.ads:
24966 Add Wide_Char_Byte_Count feature to count chars vs bytes
24968 2005-09-01 Thomas Quinot <quinot@adacore.com>
24969 Ed Schonberg <schonberg@adacore.com>
24970 Robert Dewar <dewar@adacore.com>
24972 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24973 'Address attribute reference with an overloaded prefix, use the
24974 location of the prefix (not the location of the attribute reference) as
24975 the error location.
24976 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24977 a function renaming thereof, is a valid prefix for 'Size (where it is
24978 intepreted as a function call).
24979 (Statically_Denotes_Entity): New predicate to determine whether the
24980 prefix of an array attribute can be considered static.
24983 (Eval_Attr): Fix failure to evaluate Component_Size for
24984 unconstrained arrays (resulted in wrong value in packed case, since
24985 back end cannot handle this case)
24987 2005-09-01 Robert Dewar <dewar@adacore.com>
24989 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24990 error msgs for most common cases.
24991 Use new errout insertion char < (conditional warning)
24993 2005-09-01 Javier Miranda <miranda@adacore.com>
24994 Ed Schonberg <schonberg@adacore.com>
24996 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24997 become local to the whole package.
24998 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24999 the package was already analyzed the new algorithm "replaces" the
25000 real entities by the shadow ones. This is required to ensure that
25001 the order of these entities in the homonym chains does not change;
25002 otherwise we can have undefined references at linking time because
25003 in case of conflicts the external name of the entities will have
25004 a suffix that depends on the order of the entities in the chain.
25005 (Remove_Limited_With_Clause): Complementary code that completes the
25006 new algorithm and replaces the shadow entities by the real ones.
25007 (Install_Limited_Withed_Unit): When unchaining entities before the
25008 installation of the shadow entities, only regular entities of the
25009 public part must be taken into account. This is required to
25010 keep this routine in synch with the work done by Remove_Limited_
25012 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
25013 even if unit is analyzed, because the analysis of the unit is
25014 idempotent in any case, and the limited view of the unit may have to
25015 be installed for proper visibility.
25016 (Expand_Limited_With_Clause): Even if the unit in the implicit
25017 with_clause has been analyzed already, a limited view of the package
25018 must be built for the current context, if it does not exist yet.
25020 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25021 Javier Miranda <miranda@adacore.com>
25022 Gary Dismukes <dismukes@adacore.com>
25024 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
25025 defining entity for the instance body, make a new defining identifier
25026 rather than copying the entity of the spec, to prevent accidental
25027 sharing of the entity list.
25028 (Check_Private_View): When exchanging views of private types, build the
25029 list of exchanged views as a stack, to ensure that on exit the exchanges
25030 are undone in the proper order.
25031 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
25032 Restore the compilation environment in case of instantiation_error.
25033 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
25034 for an anonymous access result.
25035 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
25036 (Formal_Entity): Handle properly the case of a formal package that
25037 denotes a generic package renaming.
25039 2005-09-01 Thomas Quinot <quinot@adacore.com>
25041 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
25042 clause if the array aggregate is surrounded by parentheses.
25044 2005-09-01 Cyrille Comar <comar@adacore.com>
25045 Gary Dismukes <dismukes@adacore.com>
25046 Ed Schonberg <schonberg@adacore.com>
25047 Javier Miranda <miranda@adacore.com>
25049 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
25051 to check if a type is Constrained in cases related to code generation
25052 (rather than semantic checking) since otherwise we do not generate
25053 similar code for mutable private types depending if their
25054 discriminants are visible or not.
25055 (Check_Abstract_Overriding): Do not complain about failure to override
25056 the primitive operations used in dispatching selects since they will
25057 always be overriden at the freeze point of the type.
25058 (Access_Definition): Separate out handling for resetting the scope
25059 of an anonymous access function result type. Retrieve the scope
25060 of the associated function rather than using Current_Scope, which
25061 does not have a consistent value (depends on whether we're in the
25062 middle of analyzing formal parameters). Add ??? comment about
25063 finding a cleaner way to handle the special cases of scope setting.
25064 (Process_Incomplete_Dependents): A protected operation is never a
25065 dispatching operation (only its wrapper may be).
25066 (Build_Derived_Record_Type): In case of tagged private types that
25067 implement interfaces add derivation of predefined primitive
25069 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
25070 by two parameters that are used in case of derivation from abstract
25071 interface types: No_Predefined_Prims is used to avoid the derivation
25072 of predefined primitives from the interface, and Predefined
25073 Prims_Only is used to complete the derivation predefined primitives
25074 in case of private tagged types implementing interfaces.
25075 Fix typo in comments
25076 (Find_Interface_In_Descendant): Protect the frontend against
25077 wrong code with large circularity chains.
25078 (Is_Private_Overriding): Add support for entities overriding interface
25079 subprograms. The test failed because Entities associated with overriden
25080 interface subprograms are always marked as hidden (and used to build
25081 the secondary dispatch table); in this case the overriden entity is
25082 available through the field abstract_interface_alias (cf. override_
25083 dispatching_operation)
25084 (Access_Definition): Set the scope of the type to Current_Scope for the
25085 case of a function with an anonymous access result type.
25086 (Access_Subprogram_Declaration): Handle creation of the type entity for
25087 an access-to-function type with an anonymous access result.
25088 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
25089 in handling for N_Access_Function_Definition.
25090 (Analyze_Subtype_Declaration): Modify the text of error message.
25091 (Derived_Type_Declaration): Modify the text of error message.
25092 (Process_Subtype): Modify the text of error message plus cleanup
25093 of one redundant error message.
25094 (Analyze_Component_Declaration): Code cleanup.
25095 (Analyze_Object_Declaration): Code cleanup.
25096 (Analyze_Subtype_Declaration): Propagate the null-exclusion
25097 attribute in case of access types. Code cleanup.
25098 (Array_Type_Declaration): Code cleanup.
25099 (Process_Discriminants): Create the new null-excluding itype
25100 if required. Code cleanup.
25101 (Process_Subtype): Create the new null-excluding itype if
25102 required. Code cleanup.
25103 (Build_Derived_Record_Type): Code cleanup to avoid calling
25104 twice the subprogram derive_subprograms in case of private
25105 types that implement interfaces. In this particular case the
25106 subprogram Complete_Subprograms_Derivation already does the
25107 job associated with the second call.
25109 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
25110 conversion to the full view when generating an operation for a
25111 discriminant whose type may currently be private.
25113 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25114 Javier Miranda <miranda@adacore.com>
25116 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
25117 V (Obj.F), the rewriting does not involve the indexed component, but
25118 only the selected component itself.
25119 Do not apply the transformation if the analyzed node is an actual of a
25120 call to another subprogram.
25121 (Complete_Object_Operation): Retain the entity of the
25122 dispatching operation in the selector of the rewritten node. The
25123 entity will be used in the expansion of dispatching selects.
25124 (Analyze_One_Call): Improve location of the error message associated
25126 (Analyze_Selected_Component): No need to resolve prefix when it is a
25127 function call, resolution is done when parent node is resolved, as
25129 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
25130 when attempting to resolve a call transformed from its object notation.
25131 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
25132 of the argument list for each interpretation of the operation.
25133 (Try_Object_Operation): The designated type of an access parameter may
25134 be an incomplete type obtained through a limited_with clause, in which
25135 case the primitive operations of the type are retrieved from its full
25137 (Analyze_Call): If this is an indirect call, and the return type of the
25138 access_to_subprogram is incomplete, use its full view if available.
25140 2005-09-01 Javier Miranda <miranda@adacore.com>
25141 Gary Dismukes <dismukes@adacore.com>
25143 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
25144 access types the null-exclusion and access-to-constant attributes must
25146 (Analyze_Return_Statement): When the result type is an anonymous access
25147 type, apply a conversion of the return expression to the access type
25148 to ensure that appropriate accessibility checks are performed.
25149 (Analyze_Return_Type): For the case of an anonymous access result type,
25150 generate the Itype and set Is_Local_Anonymous_Access on the type.
25151 Add ??? placeholder for check to disallow returning a limited object
25152 in Ada 2005 unless it's an aggregate or a result of a function call.
25153 Change calls from Subtype_Mark to Result_Definition.
25154 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
25155 Result_Definition in call to Make_Function_Specification.
25156 (Build_Body_To_Inline): Change Set_Subtype_Mark to
25157 Set_Result_Definition.
25158 (Make_Inequality_Operator): Change formal Subtype_Mark to
25159 Result_Definition in call to Make_Function_Specification.
25160 (Process_Formals): Create the new null-excluding itype if required.
25161 (New_Overloaded_Entity): For an entity overriding an interface primitive
25162 check if the entity also covers other abstract subprograms in the same
25163 scope. This is required to handle the general case, that is, overriding
25164 other interface primitives and overriding abstract subprograms inherited
25165 from some abstract ancestor type.
25166 (New_Overloaded_Entity): For an overriding entity that comes from
25167 source, note the operation that it overrides.
25168 (Check_Conformance, Type_Conformant): Addition of one new formal
25169 to skip controlling formals in the analysis. This is used to
25170 handle overloading of abstract interfaces.
25171 (Base_Types_Match): Add missing case for types imported from
25172 limited-with clauses
25173 (New_Overloaded_Entity): Add barrier to protect the use of
25174 the "alias" attribute.
25176 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25178 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
25179 verify that the procedure and the entry are mode conformant.
25180 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
25181 as a different operator, which is often a cut-and-paste error.
25183 2005-09-01 Javier Miranda <miranda@adacore.com>
25184 Ed Schonberg <schonberg@adacore.com>
25186 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
25187 used in controlling parameters exclude null because it is necessary to
25188 read the tag to dispatch, and null has no tag.
25189 (Override_Dispatching_Operation): If the previous operation is inherited
25190 from an interface, it becomes hidden and does not participate in later
25193 2005-09-01 Javier Miranda <miranda@adacore.com>
25194 Ed Schonberg <schonberg@adacore.com>
25195 Gary Dismukes <dismukes@adacore.com>
25197 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
25198 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
25199 the expander will generate the corresponding run-time check to evaluate
25201 (Resolve_Call): Check for legal type of procedure name or prefix that
25202 appears as a trigger in a triggering alternative.
25203 (Valid_Conversion): If expression is ambiguous and the context involves
25204 an extension of System, remove System.Address interpretations.
25205 (Resolve_Qualified_Expression): Reject the case of a specific-type
25206 qualification applied to a class-wide argument. Enhance comment
25207 to explain checking of Original_Node.
25208 (Resolve_Type_Conversion): The location of the error message was not
25209 general enough to handle the general case and hence it has been removed.
25210 In addition, this patch improves the text of the message.
25211 (Resolve_Type_Conversion): Add missing support for access to interface
25213 (Resolve_Type_Conversion): If the target is a class-wide interface type,
25214 do not expand if the expression is the actual in a call, because proper
25215 expansion will take place when the call itself is expanded.
25216 (Resolve_Allocator): If the context is an unchecked conversion, the
25217 allocator inherits its storage pool, if any, from the target type of
25220 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25221 Javier Miranda <miranda@adacore.com>
25223 * sem_type.adb (Add_One_Interp): If a candidate operation is an
25224 inherited interface operation that has an implementation, use the
25225 implementation to avoid spurious ambiguities.
25226 (Interface_Present_In_Ancestor): In case of concurrent types we can't
25227 use the Corresponding_Record_Typ attribute to look for the interface
25228 because it is set by the expander (and hence it is not always
25229 available). For this reason we traverse the list of interfaces
25230 (available in the parent of the concurrent type).
25231 (Interface_Present_In_Ancestor): Handle entities from the limited view
25233 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25235 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
25236 from the list of required components.
25237 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
25238 primitive procedure of a limited interface with a controlling first
25240 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
25242 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25243 capture if it is generated in the second operand of a short-circuit
25245 Do not capture values for variables with address clauses.
25246 (Is_Object_Reference): Treat a function call as an object reference only
25247 if its type is not Standard_Void_Type.
25249 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25251 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
25252 to a variable that is statically known to be constant.

25264 Document that bounds of result of Base_Name match the input index
25266 Add documentation on environment variable syntax for Expand_Path
25268 * gnat_ugn.texi: Update documentation to include mention of -m switches
25269 Document new treatment of wide characters in max line length
25271 Remove -gnatL/-gnatZ switches, no longer used.
25272 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
25275 * gnat_rm.texi: Add doc for two argument form of pragma
25276 Float_Representation.
25277 Add documentation for pragma No_Strict_Aliasing

26034 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
26035 longer protected objects. They have been replaced by lower-level
26036 suspension objects made up by a mutex and a condition variable (or
26037 their equivalent given a particular OS) plus some internal data to
26038 reflect the state of the suspension object.
26039 (Initialize, Finalize): Add this initialization procedure for
26040 Suspension_Object, which is a controlled type.

26042 which is a controlled type.
26044 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
26045 Ada.Synchronous_Task_Control because there is no longer a need for a

26047 has been moved to System.Task_Primitives.Operations.
26049 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
26051 (InitializeCriticalSection, EnterCriticalSection,
26052 LeaveCriticalSection, DeleteCriticalSection): Replace the type

26499 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
26500 access to subprograms must be recursive.
26501 (Is_Unchecked_Conversion): Improve the test that recognizes
26502 instantiations of Unchecked_Conversion, and allows them in bodies that
26503 are to be inlined by the front-end. When the body comes from an
26504 instantiation, a reference to Unchecked_Conversion will be an
26505 Expanded_Name, even though the body has not been analyzed yet.

26524 * sem_res.adb (Valid_Conversion): Perform an accessibility level check
26525 in the case where the target type is an anonymous access type of an
26526 object or component (that is, when Is_Local_Anonymous_Access is true).
26527 Prevent the special checks for conversions of access discriminants in
26528 the case where the discriminant belongs to a nonlimited type, since
26529 such discriminants have their accessibility level defined in the same
26530 way as a normal component of an anonymous access type.
26531 (Resolve_Allocator): When an allocator's designated type is a class-wide
26532 type, check that the accessibility level of type given in the
26533 allocator's expression or subtype indication is not statically deeper
26534 than the level of the allocator's access type.

26545 (Resolve_Actuals): Enable full error reporting on view conversions
26546 between unrelated by_reference array types.
26547 The rule for view conversions of arrays with aliased components is
26548 weakened in Ada 2005.
26549 Call to obsolescent subprogram is now considered to be a violation of
26550 pragma Restrictions (No_Obsolescent_Features).
26551 (Check_Direct_Boolean_Operator): If the boolean operation has been
26552 constant-folded, there is nothing to check.
26553 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26554 check on possible violation of restriction No_Direct_Boolean_Operators
26555 until after expansion of operands, to prevent spurious errors when

26588 constrained partial view.
26590 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
26591 both bound checks, rather than a conjunction.
26592 (Insert_Valid_Check): If the expression is an actual that is an indexed
26593 component of a bit-packed array, force expansion of the packed element
26594 reference, because it is specifically inhibited elsewhere.

26604 current working directory to object directory of a project.
26605 (Gnatmake): Remove exception handler that could no longer be exercized
26606 (Compile_Sources.Compile): Use deep copies of arguments, as some of them
26607 may be deallocated by Normalize_Arguments.
26608 (Collect_Arguments): Eliminate empty arguments
26610 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
26611 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.

27560 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
27561 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
27562 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
27563 analyzed if expansion is disabled (which could otherwise cause spurious
27564 error messages if expansion has been disabled due to previous
27565 (unrelated) errors).
27567 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
27568 is disabled, the entity denoted by the argument is the access type
27569 itself, not an underlying record type, so there is no need to go back
27570 to the Corresponding_Remote_Type.
27572 2005-03-29 Gary Dismukes <dismukes@adacore.com>
27573 Robert Dewar <dewar@adacore.com>
27575 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
27576 expand a call to an instance of
27577 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the

27579 check is also generated, to ensure that the tag passed to the instance
27580 denotes a type in the class.
27581 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
27582 of Name_Generic_Dispatching_Constructor.
27584 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

27600 generic formal subprogram association for an abstract formal subprogram.
27601 Check that the attribute is a primitive stream attribute (and not
27602 a class-wide stream attribute) and then rewrite the attribute name
27603 as the name of the appropriate compiler-generated stream primitive.
27605 2005-03-29 Robert Dewar <dewar@adacore.com>
27607 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

27615 itype whose parent is controlled and not yet frozen, do not create a
27616 freeze node for the itype if expansion is disabled.
27618 2005-03-29 Vincent Celier <celier@adacore.com>
27620 * make.adb (Gnatmake): Don't fail if the main project file is declared
27621 as having no Ada sources. Do not display message "no sources to
27622 compile" in quiet output.
27624 2005-03-29 Doug Rupp <rupp@adacore.com>
27626 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

27642 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
27643 rather than proceed ahead using a junk attribute name.
27645 2005-03-29 Vincent Celier <celier@adacore.com>
27647 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
27649 * prj-part.adb (Parse_Single_Project): Set the location of a project
27650 on its defining identifier, rather than on the reserved word "project".
27652 * prj-proc.adb (Expression): Adapt to the fact that default of external
27653 references may be string expressions, not always literal strings.
27654 (Recursive_Process): Set Display_Name equal to Name
27655 when Location is No_Location, that is when there is no actual file.
27656 Get the Display_Name of the project from the source, when it is not a
27658 (Process): Use the Display_Name in error messages
27660 * prj-strt.adb (External_Reference): Allow default to be string
27661 expressions, not only literal strings.
27663 2005-03-29 Vincent Celier <celier@adacore.com>

27670 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
27671 forbid conversion of a local access-to-subprogram type to a remote one.
27673 * sem_util.adb (Wrong_Type): For a record type that is the expanded
27674 equivalent type for a remote access-to-subprogram type, go back to the
27675 original RAS entity when displaying an error message, so the casing is
27676 the original source casing.

27680 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
27683 2005-03-29 Ed Schonberg <schonberg@adacore.com>
27685 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
27686 subtype if code is being pre-analyzed, to prevent un-expanded
27687 references to protected formals, among others.
27688 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
27689 interpretation that can be a call, include the result of the call as a
27690 possible interpretation of the dereference.
27692 * sem_ch5.adb (Process_Bounds): Determine type of range by
27693 pre-analyzing a copy of the original range, and then analyze the range
27694 with the expected type.
27696 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
27697 with an overloaded prefix where not all interpretations yield an
27698 access to subprogram, do not rewrite node as a call.
27699 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
27700 the node as a call once the context identifies the interpretation of
27701 the prefix whose call yields the context type.
27702 (Valid_Conversion): For the case of a conversion between
27703 local access-to-subprogram types, check subtype conformance using
27704 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
27705 detailed error message.

27709 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
27710 indicator, indicate that the formal can never be null.
27711 (Process_Formals): If a formal has a non_null indicator, insert the
27712 resulting subtype immediately before the enclosing subprogram decl,
27713 and not at the beginning of the corresponding declarative part, to
27714 prevent access before elaboration (Ada2005).

27823 to install the visible declarations of the enclosing scope of a
27824 record_type_with_private to establish the proper visibility before
27825 freezing the entity and related subprograms.

27836 into a new Check_Attr subprogram, in order to provide a more
27837 explanatory error message (including the name of the missing attribute).
27838 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
27839 subprogram determines whether a default implementation exists for a
27840 given stream attribute.
27841 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
27842 Determine whether to generate a default implementation for each stream
27843 attribute separately, as this depends on the specific attribute.
27845 * exp_strm.adb (Make_Field_Attribute): For the case of an illegal
27846 limited extension where a stream attribute is missing for a limited
27847 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27932 (Unlock): Remove the ownership of the protected object.
27934 * s-taprob.ads (Protection): Add the field Owner, used to store the
27935 protected object's owner.

28382 or task subtype entity to leave a field free to store the list
28383 of interfaces implemented by a task (for AI-345)

28396 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
28399 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
28402 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
28403 attribute Task_Body_Procedure rather than the old semantic field that
28404 was available in the task_type_declaration node.
28406 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
28407 interface type definitions.
28408 (P_Formal_Derived_Type_Definition): Modified to handle the list of
28411 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
28412 task type declaration.
28413 (P_Protected): Modified to handle the list of interfaces in a
28414 protected type declaration.
28416 2005-03-15 Doug Rupp <rupp@adacore.com>
28417 Vincent Celier <celier@adacore.com>
28419 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
28420 (Gen_Output_File_C): Likewise.
28421 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
28423 2005-03-15 Thomas Quinot <quinot@adacore.com>
28425 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
28426 is an N_Raise_Constraint_Error node, create a new copy of it without
28427 going through a call to Duplicate_Subexpr.
28429 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>

28432 Ed Schonberg <schonberg@adacore.com>
28438 * decl.c (gnat_to_gnu_field): Reject aliased components with a
28439 representation clause that prescribes a size not equal to the rounded
28440 size of their types.
28441 (gnat_to_gnu_entity, case E_Component): Always look at
28442 Original_Record_Component if Present and not the entity.

28444 of tagged extension types by not making field for components that are
28446 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
28447 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
28448 expression to the type of the object when the object is constant.
28449 Reverse defer_debug_incomplete_list before traversing it, so that trees
28450 are processed in the order at which they were added to the list. This
28451 order is important when using the stabs debug format.
28452 If we are deferring the output of debug information, also defer this
28453 output for a function return type.
28454 When adding fields to a record, prevent emitting debug information
28455 for incomplete records, emit the information only when the record is
28457 (components_to_record): New parameter defer_debug.
28458 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
28459 (gnat_to_gnu_field_decl): New function.
28460 (substitution_list, annotate_rep): Call it.
28461 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
28462 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
28463 No longer update discriminants to not be a COMPONENT_REF.
28464 (copy_alias_set): Strip padding from input type; also handle
28465 unconstrained arrays properly.
28467 * gigi.h (write_record_type_debug_info): New function.
28468 Convert to use ANSI-style prototypes. Remove unused
28469 declarations for emit_stack_check, elab_all_gnat and
28470 set_second_error_entity.
28471 (gnat_to_gnu_field_decl): New decl.
28473 * utils.c (write_record_type_debug_info): New function.

28476 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
28477 (update_pointer_to): Fix pasto.
28478 (convert) <UNION_TYPE>: Accept slight type variations when
28479 converting to an unchecked union type.
28481 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
28482 replace the N_Freeze_Entity with a null statement.
28484 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
28485 within a constrained subcomponent of an enclosing record, place the
28486 freeze nodes in the scope stack entry for the enclosing record.
28487 (Undelay_Type): New Subprogram.
28488 (Set_Small_Size): Pass T, the type to modify; all callers changed.
28489 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
28490 within records; allow them to have freeze nodes if their base types
28493 * exp_util.adb (Remove_Side_Effects): Properly test for
28494 Expansion_Delayed and handle case when it's inside an
28495 N_Qualified_Expression.
28497 * sem_ch3.adb (Derived_Type_Declaration): New predicate
28498 Comes_From_Generic, to recognize accurately that the parent type in a
28499 derived type declaration can be traced back to a formal type, because
28500 it is one or is derived from one, or because its completion is derived
28502 (Constrain_Component_Type): If component comes from source and has no
28503 explicit constraint, no need to constrain in in a subtype of the
28505 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
28506 Minor change to propagate Is_Ada_2005 flag
28508 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
28509 Expansion_Delayed is False.
28510 (assoc_to_constructor): Ignore fields that have a
28511 Corresponding_Discriminant.
28512 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
28513 function returns "by target", dereference the target pointer using the
28514 type of the actual return value.
28515 <all>: Be prepared for a null gnu_result.
28516 (processed_inline_subprograms): Check flag_really_no_inline
28517 instead of flag_no_inline.
28518 (set_second_error_entity): Remove unused function.

28524 Ed Schonberg <schonberg@adacore.com>
28525 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28527 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
28528 Must_Be_Byte_Aligned for cases where we do not need to use a
28529 System.Pack_nn unit.
28531 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
28533 Needed now that we do some processing for IN parameters as well. This
28534 may well fix some unrelated errors.
28535 (Expand_Call): Handle case of unaligned objects (in particular those
28536 that come from packed arrays).
28537 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
28538 renamed entity is an inherited operation, re-expand the call using the
28539 original operation, which is the one to call.
28540 Detect attempt to inline parameterless recursive subprogram.
28541 (Represented_As_Scalar): Fix to work properly with private types
28542 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
28543 accurate estimate. Yields True in far fewer cases than before,
28544 improving the quality of code that depends on this test.
28546 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
28547 over both visible and private declarations to remove them from tree,
28548 and mark subprograms declared in package as eliminated, to prevent
28549 spurious use in subsequent compilation of generic units in the context.
28551 * exp_util.ads: Minor cleanup in variable names
28553 * sem_eval.ads, sem_eval.adb: Minor reformatting
28554 (Compile_Time_Known_Bounds): New function
28556 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28558 * exp_ch7.adb (Convert_View): Use base types of underlying types when
28559 determining whether an unchecked conversion is needed for the argument
28560 of an initialization call.
28562 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28564 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
28565 that appears in the instantiation rather than the internal subtype
28566 generated in the wrapper package, to avoid anomalies in gigi when the
28567 target is derived from a private type whose full view is an access type.
28569 2005-03-15 Robert Dewar <dewar@adacore.com>
28571 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
28573 Add documentation to replace the use of this flag
28574 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
28577 2005-03-15 Thomas Quinot <quinot@adacore.com>
28579 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
28580 here from exp_attr so it can be shared between exp_attr and exp_dist.
28581 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
28582 all TSS names, not a subset thereof, and the previous name introduced
28583 an unnecessarily confusion that a distinction might exist between
28584 "OK" TSS names and some "not OK" TSS names.
28586 2005-03-15 Doug Rupp <rupp@adacore.com>
28588 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
28591 2005-03-15 Pascal Obry <obry@adacore.com>
28592 Eric Botcazou <ebotcazou@adacore.com>
28596 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
28597 when IN_RTS. This is to work around a bootstrap path problem.
28599 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
28600 table and pass it to __gnat_install_SEH_handler().
28601 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
28603 * lang.opt: Fix specification of -fRTS=.
28605 2005-03-15 Doug Rupp <rupp@adacore.com>

28607 Vincent Celier <celier@adacore.com>
28608 Arnaud Charlet <charlet@adacore.com>
28611 This change works fine when gnatlib is built from the gcc directory,
28612 but does not work when using the libada Makefile, since GCC_FOR_TARGET
28613 is not passed to ada/Makefile.in, so more work is needed by a
28614 Makefile/configure expert.
28616 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
28617 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
28618 Setup gnatlink switch -M for x86_64 linux, as it is already setup
28620 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
28621 Run ranlib on libgccprefix.a
28622 Define PREFIX_OBJS for Darwin, to build libgccprefix.
28623 (ADA_INCLUDE_SRCS): Split Ada packages.
28625 2005-03-15 Robert Dewar <dewar@adacore.com>
28627 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
28629 * impunit.adb: Add GNAT.UTF_32
28631 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
28633 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
28634 now uses GNAT.UTF_32).
28636 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
28637 capabilities for categorizing characters using Unicode categories
28639 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28641 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
28642 instantiation that has been rewritten as a package body, retrieve spec
28643 to generate proper name for implicit_with_clause.
28644 (Install_Parents): Recognize a parent that is an instantiation but has
28645 been rewritten as a package declaration during analysis.
28647 2005-03-15 Javier Miranda <miranda@adacore.com>
28648 Ed Schonberg <schonberg@adacore.com>
28650 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
28651 parameter reported some error we immediately return. This improves the
28652 behaviour of the frontend in case of errors.
28653 (Install_Parent, Remove_Parent): Introduce new flag
28654 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
28655 ancestor of a generic child unit, when the child is being instantiated.
28656 (Inline_Instance_Body): If we are compiling the private
28657 part or the body of a child unit, restore the proper visibility of the
28658 parents after compiling the instance body.
28660 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28661 Javier Miranda <miranda@adacore.com>
28664 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28665 of a private type, in which case it is underlying_type that denotes
28666 the proper task. Also modified to use the new entity attribute
28667 that is directly available in the task type and task subtype entities
28668 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28669 arrays when other dimensions than the first are constrained by
28670 discriminants of an enclosing record.
28671 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28672 a combination of indexed and selected components, find ultimate entity
28673 and generate the appropriate reference for it, to suppress spurious
28675 (Note_Possible_Modification): If an entity name has no entity, return.
28676 (Is_Variable): A function call never denotes a variable.
28677 (Requires_Transient_Scope): For record types, recurse only on
28678 components, not on internal subtypes that may have been generated for
28679 constrained components.
28681 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28683 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28684 Eliminated as candidates for resolution. Both efficient, and avoids
28685 anomalies with operators declared in deleted code.
28686 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28687 expansion is disabled (as when compiling a generic) to prevent spurious
28688 warnings on prefixes of selected components.
28690 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28692 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28693 attached to a list before checking whether it appears in the private
28694 declarations of the current package.
28695 (Make_Inequality_Operator): Insert declaration in proper declarative
28696 list rather than just setting the Parent field, so that
28697 Is_Private_Declaration can handle it properly.
28699 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28701 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28702 a renaming a body, check that the renamed subprogram in not intrinsic.
28703 (Find_Direct_Name): If several use_visible entities hide
28704 each other, and the context is a predefined file compiled through
28705 rtsfind, keep only the entity that comes from a predefined file.
28707 2005-03-15 Geert Bosch <bosch@adacore.com>
28709 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28710 long float padding to also cover AMD64 and IA64.
28712 2005-03-15 Gary Dismukes <dismukes@adacore.com>
28714 * s-imgwch.adb: Add with and use of Interfaces.
28715 (Img_Wide_Character): Change type of Val to Unsigned_16.
28716 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
28718 2005-03-15 Matthew Gingell <gingell@adacore.com>
28720 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.

28763 Cyrille Comar <comar@adacore.com>
28764 Sergey Rybin <rybin@adacore.com>
28766 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
28767 too specific and long-winded to be appropriate for the GNAT User's
28769 Warn about use of GCC switches not documented in the GNAT User's Guide,
28770 as these may cause generated code to not conform to Ada semantics.
28771 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
28772 Add documentation for -gnat95 and -gnat05 switches
28773 Remove paragraph documenting obsolete way to refer to third party

29192 the formal subprogram.
29193 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
29194 which is an unclean use of that field, we set the new field

29221 procedure", covering the case of a call to a formal abstract procedure
29222 that has statically tagged operands.

29224 a tag-indeterminate function call whose type is an ancestor of the

29357 address of the exception registration. The Win32 version of this
29358 routine calls __gnat_install_SEH_handler() to initialize the SEH
29359 (Structured Exception Handling) handler.
29360 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
29361 SEH (Structured Exception Handling) now.
29362 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
29363 (__gnat_initialize for ppc-vxworks): Adjust comments and the
29364 preprocessor condition protecting the call to the extra eh setup
29365 subprogram, which is only available for the ppc target.
29366 (__gnat_clear_exception_count): replaced reference to
29367 variable taskIdCurrent by call to taskIdSelf(), cleaner.
29369 * seh_init.c: New file.
29371 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
29372 (GNATBIND_OBJS): Idem.
29374 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
29375 routine takes a new parameter (a pointer to the exception registration
29376 for the SEH (Structured Exception Handling) support.
29378 * raise.h: (__gnat_install_SEH_handler): New prototype.
29379 Update copyright notice.
29381 * s-tassta.adb (Task_Wrapper): Declare the exception registration
29382 record and initialize it by calling __gnat_install_SEH_handler.
29384 2005-02-09 Vincent Celier <celier@adacore.com>
29386 * make.adb (Gnatmake): Do not fail when the main project has no object
29389 2005-02-09 Doug Rupp <rupp@adacore.com>
29391 * Makefile.in [VMS] (LN,LN_S): Define as cp -p
29392 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
29393 [VMS]: Add translations for g-enblsp.adb.
29395 * s-asthan-vms.adb: Removed.
29396 * s-asthan-vms-alpha.adb: Added.
29398 2005-02-09 Pascal Obry <obry@adacore.com>
29400 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.
29401 (LIBGNAT_OBJS): Add seh_init.o.
29403 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29406 * Makefile.in: Link all gnat tools with -static-libgcc, since
29407 -shared-libgcc is now used by default on some systems (e.g. linux with
29409 Remove references to Makefile.prolog/generic, no longer used.
29411 2005-02-09 Vincent Celier <celier@adacore.com>
29413 * prj-makr.adb (Process_Directory): Put file name in canonical case
29414 before matching against the patterns.
29415 If gnatname has been invoked as <prefix>-gnatname
29416 then invoke the compiler as <prefix>-gcc, not just "gcc".
29418 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29420 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
29421 with expansion disabled. The actual subtype is needed among other
29422 places when the selected component appears in the context of a loop
29423 bound, and denotes a packed array.
29424 (Operator_Check): Always use the first subtype in the
29425 error message, to avoid the appearance of internal base types.
29426 (Transform_Object_Operation): Copy each actual in full
29427 to the parameter associations of the constructed call, rather than
29428 using the shallow copy mechanism of New_Copy_List. This ensures that
29429 the chaining of named associations is done properly.
29430 (Complete_Object_Operation): Rewrite node, rather than
29431 replacing it, so that we can trace back to the original selected
29434 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
29435 and calls that use object notation, if the called function is not
29436 declared in a withed unit, place the elaboration constraint on the
29437 unit in the context that makes the function accessible.
29438 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
29439 imposes an elaboration constraint between two packages.
29441 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29443 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
29444 views of a private type after handling its private dependents, to
29445 maintain proper stack discipline between entry and exit from the
29448 2005-02-09 Cyrille Comar <comar@adacore.com>
29450 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.
29451 Minor reformatting.
29453 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29455 * s-tporft.adb (Register_Foreign_Thread): Initialize Task_Image[_Len]
29456 fields for foreign threads.
29458 2005-02-09 Doug Rupp <rupp@adacore.com>

29461 recursion warnings when compiled with -gnatdm.
29463 2005-02-09 Robert Dewar <dewar@adacore.com>
29465 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
29466 Slight fix to documentation of -gnaty with no parameters
29468 * xr_tabls.ads: Add ??? comment for missing overall comment
29470 * xsinfo.adb: Make default file name be sinfo.h, since this is what
29471 we now use by default.
29473 * xsnames.adb: Adjust end of file test to look for five space followed
29474 by '#' instead of six spaces. The format of xsnames.adb was modified
29475 in the last update.
29477 * a-numeri.ads: Add reference to AI-388 for greek letter pi
29480 * clean.adb: Minor reformatting.
29482 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
29483 gnatname.adb: Minor reformatting
29484 Add 2005 to copyright output when utility is run
29486 * csets.adb: Eliminate obsolete comment
29488 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
29491 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
29493 2005-02-09 Sergey Rybin <rybin@adacore.com>
29495 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
29496 the difference between compact and incompact layout and add the record
29497 representation clause to the example illustrating different layouts.
29498 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
29499 component clauses").
29501 2005-02-09 Florian Villoing <villoing@adacore.com>
29503 * gnat_ugn.texi: Fix typos.
29504 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
29506 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
29507 in the generated documentation.
29509 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29511 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
29513 Update linker wrapper when linking with non GNU C++.
29515 2005-02-09 Pascal Obry <obry@adacore.com>
29518 Document the procedure to debug the DllMain routine on Windows.
29519 Add note about -funwind-tables and mixed Ada and C/C++ programming in
29521 Document new BIND qualifer /RETURN_CODES=VMS.

29551 * exp_util.ads: Minor correction in comment.
29553 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29555 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
29556 since this procedure is now too complex to be worth inlining.
29558 2005-02-09 Richard Henderson <rth@redhat.com>
29560 * utils.c (gnat_define_builtin): Remove.
29561 (gnat_install_builtins): Use build_common_builtin_nodes.

29694 (Resolve_Access, case 'Access): Note that GNAT uses the context type to
29695 disambiguate overloaded prefixes, in accordance with AI-235. GNAT code
29696 predates, and partly motivates, the adoption of the AI.
29697 Implement new Ada 2005 attribute Mod

29734 * scng.ads, scng.adb: Always allow wide characters in Ada 2005 mode, as
29735 specified by AI-285, needed for implementation of AI-388 (adding greek

29743 restrictions lines.
29744 (Scan_ALI): When finding an unexpected character on an R line, raise
29745 exception Bad_R_Line, instead of calling Fatal_Error, so that, when
29746 Ignore_Errors is True, default restrictions are set and scanning of the
29747 ALI file continues with the next line. Also, when Bad_R_Line is raised
29748 and Ignore_Errors is True, skip to the end of le line.
29750 * sem_ch10.adb: Check that explicit with's do not violate
29751 No_Dependence restrictions.
29752 (Install_Withed_Unit): Add code to implement AI-377 and diagnose
29753 illegal context clauses containing child units of instance.
29755 * sem_prag.adb: Processing and checking for new No_Dependence
29757 (Analyze_Pragma, case Psect_Object): Call Check_Arg_Is_External_Name to

29787 Enable mlib-tgt-lynxos.adb on lynxos.
29789 * Make-lang.in: Remove rules for gpr2make.
29790 When generating sdefault.adb, do not call Relocate_Path

29800 address is incompatible with its base type alignment constraints when
29801 this can be decided statically.
29803 2005-01-03 Olivier Hainque <hainque@adacore.com>
29805 * decl.c (compatible_signatures_p): New function. The intended purpose
29806 is to check if two function signatures for a call-site and a callee are
29807 compatible enough for the call to be valid. The underlying purpose is
29808 to check if a call to a mapped builtin is using the right interface.
29809 The current code actually does not check antyhing - this a placeholder
29810 for future refinements.
29811 (gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle
29812 builtin calls for convention Intrinsic.
29814 * gigi.h (builtin_decl_for): Declare (new function).

30348 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
30349 used to record an implicit dereference as a read operation on its
30350 prefix when operating under -gnatc. Necessary to avoid spurious
30351 'variable assigned but never read' warnings in that mode.
30352 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
30353 is a non-overloaded implicit dereference, call the above subprogram to
30354 ensure proper recording of references.
30356 2004-12-07 Gary Dismukes <dismukes@adacore.com>
30358 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
30359 to be resolved later as part of Analyze_Iteration_Scheme's call to
30362 2004-12-07 Ed Schonberg <schonberg@adacore.com>
30364 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the
30365 prefix is not a scalar type, place error message on prefix, not on

30370 * vxaddr2line.adb: Add support for x86 vxworks
30372 2004-12-07 Thomas Quinot <quinot@adacore.com>
30374 * g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
30375 documentation of the behaviour of these functions when passed an IP
30376 address that has no record in the system hosts database and no reverse
30379 * cstand.adb, a-tags.ads: Fix typos in comment.
30381 2004-12-07 Robert Dewar <dewar@adacore.com>
30383 * exp_ch2.adb, exp_ch3.adb, exp_ch5.adb, exp_ch8.adb,

30396 2004-12-07 Vincent Celier <celier@adacore.com>
30397 Sergey Rybin <rybin@adacore.com>
30399 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
30400 Files" with the new tool and package names.
30401 Reformatting to suppress most of the warnings for line too long
30402 Document the new section "Project Search Path:" in the output of
30404 Add gnatmetric section
30406 2004-12-07 Vincent Celier <celier@adacore.com>
30408 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
30409 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
30410 and -eit to -ept. Added qualifier
30411 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
30413 2004-11-27 Andreas Schwab <schwab@suse.de>
30415 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
30417 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30419 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
30420 internal implementation unit GNAT.Sockets.Thin,
30421 as their usage for sockets is non-portable (using the read and write
30422 functions from the system runtime library is fine on UNIX but won't
30423 work under Windows).
30425 * mingw32.h: Update copyright notice.
30427 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30429 * ada-tree.h: Minor reformatting of previous change to avoid lines
30430 longer than 79 characters.
30432 2004-11-25 Olivier Hainque <hainque@adacore.com>
30434 * tb-gcc.c: GCC infrastructure based implementation of

30448 2004-11-21 Andreas Jaeger <aj@suse.de>
30450 * stylesw.adb: Change Style_Check_Subprogram_Order to
30451 Style_Check_Order_Subprograms.
30453 2004-11-18 Arnaud Charlet <charlet@adacore.com>
30455 * adaint.h, adaint.c
30456 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
30458 Add also a cast to kill another warning.
30459 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
30460 parameter with the priority class of the parent process instead of
30461 always using the NORMAL_PRIORITY_CLASS.
30462 (__gnat_dup): New function.
30463 (__gnat_dup2): New function.
30464 (__gnat_is_symbolic_link): Enable the effective body of this
30465 function when __APPLE__ is defined.
30467 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
30470 2004-11-18 Olivier Hainque <hainque@adacore.com>
30472 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
30473 address of which may be used to represent "others" and "all others"
30474 choices in exception tables, instead of the current harcoded
30475 (void *)0 and (void *)1.
30476 (Setup_Exception): Do nothing in the GNAT SJLJ case.
30478 * gigi.h (others_decl, all_others_decl): New decls representing the
30479 new Others_Value and All_Others_Value objects.
30480 (struct attrib): Rename "arg" component as "args", since GCC expects a
30481 list of arguments in there.
30483 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
30484 corresponding objects exported by a-exexpr, instead of hardcoded dummy
30487 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
30488 others_decl and all_others_decl instead of hardcoded dummy addresses
30489 to represent "others" and "all others" choices, which is cleaner and
30490 more flexible with respect to the possible eh pointer encoding policies.
30492 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
30493 (process_attributes): Account for the naming change of the "args"
30494 attribute list entry component.
30496 * decl.c (build_attr_list): Rename into prepend_attributes to allow
30497 cumulating attributes for different entities into a single list.
30498 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
30499 attributes for the current entity and propagate first subtype
30500 attributes to other subtypes.
30501 <E_Procedure>: Attribute arguments are attr->args and not
30502 attr->arg any more.
30503 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
30504 argument provided, as this is what GCC expects. Use NULL_TREE instead
30507 2004-11-18 Robert Dewar <dewar@adacore.com>
30509 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
30510 Minor reformatting througout (including new function specs)
30511 Add ??? comments asking for clarification.
30513 2004-11-18 Thomas Quinot <quinot@adacore.com>
30515 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
30516 incomplete duplicate implementation of this subprogram from butil.
30518 2004-11-18 Thomas Quinot <quinot@adacore.com>
30520 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
30521 procedures factors the common processing for building an RPC receiver
30522 for an RCI package or an RACW type.
30523 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
30524 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
30525 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
30527 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
30529 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
30531 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
30532 distribution subprogram identifiers that are either subprogram numbers
30534 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
30535 string distribution identifiers assigned to a given subprogram.
30536 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
30537 (Add_RAS_Dereference_TSS): Add comments.
30538 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
30539 is not referenced yet because it will be used by the PolyORB DSA
30541 (Insert_Partition_Check): Remove fossile code.
30542 (First_RCI_Subprogram_Id): Document this constant.
30543 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
30545 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
30546 replaced with calls to Get_Library_Unit_Name_String. Previously there
30547 were several instances of the same code in different locations in the
30548 compiler; this checkin completes the replacement of all of these
30549 instances with calls to a common subprogram.
30550 Minor reformatting.
30552 * sem_dist.adb: Remove comment noting that RPC receiver generation
30553 should be disabled for RACWs that implement RASs.
30554 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
30556 * sem_util.ads, sem_util.adb (Has_Stream): New function
30557 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
30558 qualified name of a library unit into the name buffer.
30559 (Note_Possible_Modification): Generate a reference only
30560 if the context comes from source.
30562 * snames.ads (PCS_Names): New subtype corresponding to names of
30563 supported implementations of the Partition Communication Subsystem
30564 (PCS) (i.e. the runtime library support modules for the distributed

30574 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
30576 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
30578 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
30579 (Expand_Pragma_Psect_Object): New procedure
30580 These procedures contain the revised and cleaned up processing for
30581 these two pragmas. This processing was formerly in Sem_Prag, but
30582 is more appropriately moved here. The cleanup involves making sure
30583 that the pragmas are properly attached to the tree, and that no
30584 nodes are improperly shared.
30586 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
30587 pragmas to Exp_Prag, which is more appropriate.
30588 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
30589 check for duplicates Remove use of Is_Psected flag, no longer needed.
30590 Use new Make_String_Literal function with string.
30592 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30593 that are functions return universal values, that have to be converted
30594 to the context type.
30595 Use new Make_String_Literal function with string.
30596 (Get_Stream_Convert_Pragma): New function, replaces the use of
30597 Get_Rep_Pragma, which had to be kludged to work in this case.
30599 * freeze.adb: Use new Has_Rep_Pragma function
30601 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30602 function with string.
30603 Use new Has_Rep_Pragma function.
30605 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
30608 2004-11-18 Robert Dewar <dewar@adacore.com>
30610 * errout.ads, errout.adb: (First_Sloc): New function
30612 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
30613 check (-gnatyx) instead of being included as a redundant construct
30616 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
30617 Style_Check_Order_Subprograms.
30619 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
30620 stylesw.adb: Add Style_Check_Xtra_Parens
30622 * usage.adb: Add line for -gnatyx (check extra parens)
30624 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
30626 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30627 Robert Dewar <dewar@adacore.com>
30629 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30630 discriminant of a constrained subtype, analyze the copy of the
30631 corresponding constraint, because in some cases it may be only
30632 partially analyzed.
30633 Removes long-lived ??? comments.
30635 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30636 handled controlled or secondary-stack expressions within the
30637 iteration_scheme of a loop.
30639 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30640 bounds that may contain functions calls, to prevent memory leaks when
30641 the bound contains a call to a function that uses the secondary stack.
30642 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30643 generate temporaries for loop bounds that might contain function calls
30644 that require secondary stack and/or finalization actions.
30646 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30647 selected component and the selector is overloadable (not just a
30648 function) treat as function call, Analyze_Call will disambiguate if
30650 (Analyze_Selected_Component): Do not generate an actual subtype for the
30651 selected component if expansion is disabled. The actual subtype is only
30652 needed for constraint checks.
30653 (Analyze_Allocator): If restriction No_Streams is set, then do
30654 not permit objects to be declared of a stream type, or of a
30655 composite type containing a stream.
30657 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30658 No_Streams no longer prohibits with'ing this package.
30660 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30661 discriminants, but the parent base has unknown discriminants, there is
30662 no discriminant constraint to inherit. Such a discrepancy can arise
30663 when the actual for a formal type with unknown discriminants is a
30664 similar private type whose full view has discriminants.
30665 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30666 do not permit objects to be declared of a stream type, or of a
30667 composite type containing a stream.
30669 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30671 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30672 protected operations.
30674 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30675 generated name, it complicates decoding in gdb and hinders debugging
30676 of protected operations.
30677 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30678 flag for the protected entry barrier function.
30679 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30680 flag for the protected entry function.
30682 2004-11-18 Nicolas Setton <setton@adacore.com>
30684 * expect.c: Define __unix__ when __APPLE__ is defined.
30686 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30687 Darwin-specific section.
30689 * lang-specs.h: Change the placement of the %1 marker.
30690 Works around the fact that gcc adds -fPIC by default under Darwin.
30692 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30694 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30695 type of the object with the packed array type, set the Analyzed flag
30696 on the object if it is an entity or simple indexed component, to avoid
30697 spurious type errors.
30699 2004-11-18 Gary Dismukes <dismukes@adacore.com>
30701 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
30702 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
30703 separate line from the version message.
30705 2004-11-18 Ed Falis <falis@adacore.com>
30707 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
30709 (init_float): Eliminate initialization of floating point status for
30710 AE653. The instructions have no effect for vThreads.
30712 2004-11-18 Vincent Celier <celier@adacore.com>
30714 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
30715 gnatbind is invoked with -shared.
30717 2004-11-18 Jose Ruiz <ruiz@adacore.com>
30719 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30720 for Detect_Blocking which is redundant with the check done within the
30721 procedure Protected_Single_Entry_Call.
30722 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30723 Detect_Blocking which is redundant with the check done within the
30724 procedure Protected_Single_Entry_Call.
30726 2004-11-18 Vincent Celier <celier@adacore.com>
30728 * makegpr.adb (Compile): Put the compiling switches (in package
30729 Compiler and on the command line) immediately after "-c", instead of
30730 at the end of the command line invocation of the compiler, when
30731 compiling a non-Ada file.
30732 (Build_Global_Archive): When there is no need to rebuild the archive,
30733 set Global_Archive_Exists, so that the archive is passed to the linker
30736 2004-11-18 Robert Dewar <dewar@adacore.com>
30737 Sergey Rybin <rybin@adacore.com>
30740 Remove extra paren check from list of checks for redundant constructs
30741 Add documentation of new -gnatyx style check (check extra parens)
30742 Remove paragraph about gnatelim debug options.
30744 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30745 objects rather than forbidding dependencies on the package Ada.Streams.
30747 * sinfo.ads: Add ??? note that we should document pragmas passed to
30750 * g-expect.ads: Fix a few typos in the comments.
30752 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30754 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30757 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30759 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30761 2004-11-07 Andreas Schwab <schwab@suse.de>
30763 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30765 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30768 * Makefile.in (darwin): Set soext to .dylib.
30770 2004-10-26 Vincent Celier <celier@gnat.com>
30771 Thomas Quinot <quinot@act-europe.fr>
30773 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30774 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30775 there is no use of GNAT.Sockets.Constants.
30776 Remove remaining pragma Import for C_Write
30777 Remove C_Read and C_Write from internal implementation unit
30778 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30779 the read and write functions from the system runtime library is fine
30780 on UNIX but won't work under Windows).
30782 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30783 (Check_Selector): Use C_Recv instead of C_Read.
30784 Selectors are the GNAT.Sockets abstraction to perform a select()
30785 call on a set of descriptors. To allow abortion of an ongoing
30786 select operation, some data is written to a dedicated socket that
30787 is always monitored.
30788 Under Windows, the write and read library functions cannot operate
30789 on sockets, so we need to use send and recv instead, which is portable
30790 across all supported platforms.
30792 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30793 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30794 (using the read and write functions from the system runtime library is
30795 fine on UNIX but won't work under Windows).
30797 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30799 * mlib-tgt-darwin.adb: New file.
30801 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30802 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30803 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30804 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30807 * Makefile.in: Add support for building shared libraries under Darwin.
30808 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30809 the low level EH init subprogram to be called from __gnat_initialize.
30811 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30812 indicates which options to pass to the archive indexer.
30814 * mlib-utl.adb: Add support for calling ranlib with additional
30815 options. This is needed for instance under Mac OS X.
30816 (Ranlib_Options): New global variable, used to store the potential
30817 options to pass to ranlib.
30818 (Ar): Use Ranlib_Options when spawning ranlib.
30819 (Initialize): Set the value of ranlib option.
30821 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30823 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30824 instead of 8K, to reflect the real potential needs for stack-checking
30827 2004-10-26 Pascal Obry <obry@gnat.com>
30829 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30831 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30832 Windows only the initial thread stack size can be set so it is good to
30833 start we a low stack size.
30834 The OS will adjust the size as needed.
30836 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30837 Nicolas Setton <setton@act-europe.fr>
30839 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30840 "__unix__" instead of "unix".
30841 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30842 sections were just mistakenly ignored. The former is
30843 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30844 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30845 of hpux. This prevents an unwanted definition of the symbol
30846 convert_addresses in adaint.o.
30848 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30850 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30851 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30853 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30855 * a-filico.ads, a-filico.adb: fix incorrect header.
30857 2004-10-26 Javier Miranda <miranda@gnat.com>
30859 * a-ststio.ads: Fix typo in identifier
30861 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30863 * sem_ch4.adb: Minor reformatting.
30865 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30867 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30868 enabled, check the result of unary and binary operations when the
30869 expression is the right-hand side of an assignment.
30871 2004-10-26 Vincent Celier <celier@gnat.com>
30873 * clean.adb (Delete): Do not output warnings when in quiet output and
30874 not in verbose mode.
30875 (Force_Deletions): New Boolean flag, defaulted to False
30876 (Delete): Only delete a file if it is writable, and when
30877 Force_Deletions is True.
30878 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30879 (Usage): Line for new switch -f
30880 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30883 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30885 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30886 JM type only if its size matches that of the wrapper. When a size is
30887 prescribed and the field is not aliased, remove the wrapper of a JM
30888 type only if the size is not greater than that of the packed array.
30889 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30892 2004-10-26 Geert Bosch <bosch@gnat.com>
30894 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30895 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30896 (Pred): Implement in terms of Succ.
30898 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30900 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30901 unchecked conversion is safe for in-place use if the expression of the
30902 conversion is safe.
30903 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30904 be expandable in place even if the aggregate does not come from source.
30905 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30906 designated object of an allocator in place, rather than building it
30907 first on the stack. The previous scheme forces a full copy of the array,
30908 and may be altogether unsusable if the size of the array is too large
30909 for stack allocation.
30911 2004-10-26 Robert Dewar <dewar@gnat.com>
30913 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30914 compares if the component is atomic.
30916 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30917 array assignment if the component type is atomic.
30919 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30920 Eric Botcazou <ebotcazou@act-europe.fr>
30922 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30923 is aliased and is a by_reference type, do not pass by copy.
30924 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30925 detect whether the call is in the right side of an assignment or
30926 the expression of an object declaration. Recurse on component
30927 association within aggregates.
30928 Call it in the condition that determines whether the temporary is
30929 necessary for correct stack-checking.
30931 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30933 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30934 RACW_Type, used in the PolyORB version.
30935 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30936 version and the GARLIC version.
30938 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30939 Rename RCI_Info to RCI_Locator for better consistency between the
30940 GARLIC and PolyORB versions of the distributed systems annex.
30941 (DSA_Implementation_Name): This enumeration lists the possible
30942 implementations of the Partition Communication Subsystem for the
30943 Distributed Systems Annex (DSA). The three available implementations
30944 are the dummy stub implementation (No_DSA), and two versions based on
30945 two different distribution runtime libraries: GARLIC and PolyORB. Both
30946 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30948 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30951 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30952 between the GARLIC and PolyORB versions of the distributed systems
30954 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30956 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30958 * gnat1drv.adb: Suppress calling the back end when
30959 Frontend_Layout_On_Target is true.
30961 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30963 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30964 Set_Read_Only): New subprograms.
30965 These new routines allow the user to set or unset the Owner execute
30966 and Owner write permission flags on a file.
30968 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30969 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30971 2004-10-26 Matthew Gingell <gingell@gnat.com>
30973 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30975 2004-10-26 Pascal Obry <obry@gnat.com>
30977 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30978 memory before the faulting page we properly test the process read
30979 access for this address using appropriate Win32 routine.
30980 (HPUX sections): guard with "__hpux__" instead of "hpux".
30982 2004-10-26 Robert Dewar <dewar@gnat.com>
30984 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30985 entry parameter if pragma Unreferenced set, since we do not properly
30986 handle the case of multiple parameters.
30988 2004-10-26 Vincent Celier <celier@gnat.com>
30990 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30991 (Ada_Objects_Path.Add): For a library project, add to the object path
30992 the library directory only if there is no object directory or if the
30993 library directory contains ALI files.
30994 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30996 2004-10-26 Vincent Celier <celier@gnat.com>
30998 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30999 extension of library projects.
31001 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
31002 path defaults to ".:<prefix>/lib/gnat".
31003 (Parse): For an extending all project, allow direct import of a project
31004 that is virtually extended.
31006 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
31007 the specified name is directly imported, return its ID. Otherwise, if
31008 an extension of this project is imported, return the ID of the
31011 2004-10-26 Robert Dewar <dewar@gnat.com>
31013 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
31014 (Sub3): New procedure, used by Scaled_Divide
31015 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
31016 correct more than one instance of failure to propagate carries
31018 (Double_Divide): Handle overflow case of largest negative number
31019 divided by minus one.
31021 * s-arit64.ads (Double_Divide): Document that overflow can occur in
31022 the case of a quotient value out of range.
31025 2004-10-26 Robert Dewar <dewar@gnat.com>
31027 * s-bitops.adb (Bit_Eq): Remove redundant check.
31029 * s-bitops.ads: Minor comment updates
31030 Change some occurrences of Address to System.Address
31032 * s-carsi8.ads: Fix minor cut-and-paste error in comments
31034 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31036 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
31037 accessibility check to prefix that is a protected operation.
31039 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31041 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
31042 empty, post message on stub.
31044 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31045 Javier Miranda <miranda@gnat.com>
31047 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
31048 current instance appears within a unit that is directly in the context
31050 Used to determine whether the body of the instance should be analyzed
31051 immediately after its spec, to make its subprogram bodies available
31052 for front-end inlining.
31053 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
31054 constraint is not allowed on the component type (AARM 12.5.3(3))
31056 2004-10-26 Cyrille Comar <comar@act-europe.fr>
31058 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
31059 'Storage_Pool): enhance, document & limit detection of non-sharable
31062 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
31064 * s-pooglo.ads: Add more documentation now that this pool is properly
31067 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31069 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
31070 or protected type with discriminants, do not constrain the
31071 corresponding record type if the subtype declaration has no
31072 discriminant constraints. This can be the case in source code, or in
31073 the subtype declaration created to rename an actual type within an
31076 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31078 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
31079 different kind of stub (possibly wrong name for file), do not check
31081 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
31082 includes call to some function that returns an unconstrained type, do
31085 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31087 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
31088 appear in the code for the main unit. Dependencies among units in the
31089 context of the main unit are established when those other units are
31090 compiled. Otherwise spurious elaboration constraints can generate
31091 incorrect elaboration circularities.
31093 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
31094 Ed Schonberg <schonberg@gnat.com>
31096 * sem_util.adb (Is_Aliased_View): Defend against the case where this
31097 subprogram is called with a parameter that is not an object name. This
31098 situation arises for some cases of illegal code, which is diagnosed
31099 later, and in this case it is wrong to call Is_Aliased, as that might
31100 cause a compiler crash.
31101 (Explain_Limited_Type): Refine previous fix to include
31102 inherited components of derived types, to provide complete information.
31104 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
31105 is the prival for a protected object.
31106 It is necessary to mark this entity as a variable, in addition to
31107 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
31108 modified to avoid checking the Aliased flag on entities that are not
31109 objects. (Checking that flag for non-objects is erroneous and could
31110 lead to a compiler crash).
31112 2004-10-26 Robert Dewar <dewar@gnat.com>
31114 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
31115 X_Frac = 0.5, then we know that the number X must be positive.
31116 (Succ): Remove the same redundant test, and also fix the primary test
31117 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
31119 (Decompose): Add fuller comments to spec
31121 2004-10-26 Pascal Obry <obry@gnat.com>
31123 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
31124 validity (process must have read access). Set to 0 in all other cases.
31125 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
31126 violation on Win32.
31127 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
31128 segmentation violation.
31130 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
31132 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
31133 whose type is a constructed subtype of an aliased object with an
31134 unconstrained nominal subtype, convert the actual to the constructed
31135 subtype before taking its address.
31137 2004-10-26 Vincent Celier <celier@gnat.com>
31139 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
31140 (Is_Path_Name_Case_Sensitive): New function
31142 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
31143 (Base_Name, Simple_Name, Current_Directory, Compose,
31144 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
31147 2004-10-26 Cyrille Comar <comar@act-europe.fr>
31148 Vasiliy Fofanov <fofanov@act-europe.fr>
31149 Vincent Celier <celier@gnat.com>
31151 * gnat_ugn.texi: Generalize "finding memory problems" section into a
31152 "memory management issues" section and document some of the useful
31153 memory pools provided as part of the GNAT library.
31154 Remove "virtual" from declaration of A::method2 in
31155 the simple example of Ada/C++ mixed system.
31156 Library Projects may be virtually extended: their virtual extensions
31157 are not Library Projects.
31158 Added section on extending project hierarchies.
31160 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
31162 * adaint.c (__gnat_get_libraries_from_registry): Cast value
31164 (__gnat_portable_spawn): Remove const.
31166 * mingw32.h (MAXPATHLEN): Check for previous definition.
31168 2004-10-17 Matthias Klose <doko@debian.org>
31170 * gnatvsn.ads: Set gnat library version to 4.0.
31172 2004-10-05 Vincent Celier <celier@gnat.com>
31174 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
31176 2004-10-04 Laurent Guerby <laurent@guerby.net>
31179 * Makefile.in: Define and use RANLIB_FLAGS.
31181 2004-10-04 Pascal Obry <obry@gnat.com>
31183 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
31184 other x86 platforms).
31186 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
31188 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
31189 in general and triggers stack alignment adjustment for thread entry
31190 points on targets where this is necessary.
31192 2004-10-04 Bernard Banner <banner@gnat.com>
31195 * Makefile.in: Add section for powerpc linux
31196 Add variant i-vxwork-x86.ads
31198 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
31200 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
31202 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
31203 table registration calls when need be. Ensures no reference to the crt
31204 ctors symbol are issued in the SJLJ case, which avoids possible
31205 undefined symbol errors in the case of modules to be statically linked
31208 2004-10-04 Javier Miranda <miranda@gnat.com>
31210 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
31211 in-line the code corresponding to subprogram Analyze_Actuals. In
31212 addition, analyze the actuals only in case of subprogram call.
31214 2004-10-04 Ed Falis <falis@gnat.com>
31216 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
31218 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
31220 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
31221 in the documentation.
31223 2004-10-04 Robert Dewar <dewar@gnat.com>
31225 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
31227 (Analyze_Block_Statement): Add circuitry to detect following dead code
31228 (Check_Unreachable_Code): Handle case of block exit
31230 2004-10-04 Robert Dewar <dewar@gnat.com>
31232 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
31233 (XMatchD): Avoid warning for Logic_Error call
31235 2004-10-04 Robert Dewar <dewar@gnat.com>
31237 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
31238 consider expressions buried within a procedure actual to be an actual.
31239 This caused some blowups with uses of packed slices within a procedure
31242 2004-10-04 Robert Dewar <dewar@gnat.com>
31244 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
31245 longer need to be initialized to zero.
31246 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
31247 initialized to zero.
31249 * checks.adb (Expr_Known_Valid): Packed arrays are now always
31250 considered valid, even if the representation is modular. That's correct
31251 now that we no longer initialize packed modular arrays to zero.
31253 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
31254 suffixes. These are now documented as the only cases in which the
31255 debugger ignores outer records.
31256 Previously, the spec allowed arbitrary suffixes for this purpose.
31257 Change name of LJM to JM for packed array pad records
31258 Create separate section on packed array handling, and add a whole new
31259 set of comments to this section describing the situation with packed
31260 modular types and justification requirements depending on endianness.
31262 2004-10-04 Robert Dewar <dewar@gnat.com>
31264 * a-except.adb: Add a comment for last change
31266 * einfo.ads: Minor spelling correction in comment
31268 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
31270 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
31273 * sem_util.ads: Minor comment update
31275 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31277 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
31278 Inline_Always when in Configurable_Run_Time mode.
31280 * sem_prag.adb (Process_Convention): If entity is an inherited
31281 subprogram, apply convention to parent subprogram if in same scope.
31282 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
31283 when in Configurable_Run_Time mode.
31285 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31287 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
31288 class_wide type after component list has been inherited.
31290 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31292 * sem_ch12.adb (Check_Generic_Actuals): New predicate
31293 Denotes_Previous_Actual, to handle properly the case of a private
31294 actual that is also the component type of a subsequent array actual.
31295 The visibility status of the first actual is not affected when the
31296 second is installed.
31297 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
31298 make fully recursive the treatment of formals of packages declared
31300 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
31301 the above on exit from an instantiation.
31302 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
31303 current instantiation which is now complete.
31304 (Analyze_Package_Instantiation): No instantiated body is needed if the
31305 main unit is generic. Efficient, and avoid anomalies when a instance
31306 appears in a package accessed through rtsfind.
31308 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31310 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
31311 do not generate a declaration for a temporary if the call is part of a
31312 library-level instantiation.
31314 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31316 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
31317 searching for a limited component to flag.
31319 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
31320 expansion of Input, to account for the fact that the implicit call
31321 generated by the attribute reference must freeze the user-defined
31322 stream subprogram. This is only relevant to 'Input, because it can
31323 appear in an object declaration, prior to the body of the subprogram.
31325 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
31326 expansion can proceed and further errors uncovered.
31327 (Minor clean up): Fix cases of using | instead of \ for continuation
31330 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31332 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
31334 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
31335 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
31336 Use gcc_assert and gcc_unreachable.
31338 * decl.c (gnat_to_gnu_entity, case object): Check and process a
31339 specified alignment before validating size.
31340 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
31341 stripped-down declaration for the type of the inner field when making
31344 * utils.c (finish_record_type): Do not compute the size in units
31345 incrementally. Instead compute it once for the rep clause case.
31346 Use gcc_assert and gcc_unreachable.
31348 2004-10-04 Vincent Celier <celier@gnat.com>
31350 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
31352 (Is_Valid_Path_Name): Take '/' as a directory separator.
31354 2004-10-04 Vincent Celier <celier@gnat.com>
31356 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
31357 (Extended_Project) only if Extended_Project is defined, to avoid
31359 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
31361 (Parse_Single_Project): Ditto.
31363 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
31364 Add_To_Project_Path for virtual projects.
31366 2004-10-04 Vincent Celier <celier@gnat.com>
31368 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

31371 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
31372 parameter Options_2.
31374 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
31375 Build_Dynamic_Library with an empty Options_2.
31377 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
31380 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
31381 directory separator, if any.
31382 (Gprmake): Do not allow mains on the command line for library projects.
31383 Do not attempt to link when the project is a library project.
31384 (Library_Opts): New table to store Library_Options.
31385 (Build_Library): If Library_Options is specified, pass these options
31386 when building a shared library.
31388 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31390 * s-tposen.adb (Service_Entry): The object must be always unlocked at
31391 the end of this procedure now that the unlock operation was inserted
31394 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31396 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
31397 corresponding to the Preallocated_Stacks flags in System.
31398 (Get_Target_Parameters): Including the processing for
31399 Preallocated_Stacks.

31410 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
31411 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
31412 used to signal whether the compiler creates the required stacks and
31413 descriptors for the different tasks (when True) or it is done by the
31414 underlying operating system at run time (when False).
31415 It is initially set to False in all targets.
31417 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
31418 if it is supported by the target.
31419 (Make_Task_Create_Call): Pass the stack address if it has been
31420 previously created. Otherwise pass a Null_Address.
31422 * snames.adb: Add _stack.
31424 * snames.ads: Add Name_uStack. Required to allow the expander to
31425 statically allocated task stacks.
31427 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
31428 Stack_Address argument.
31429 Check that its value is equal to Null_Address because this target does
31430 not support the static stack allocation.

31439 * exp_dist.adb: Split declaration of asynchronous flag out of
31440 Add_RACW_Read_Attribute.
31441 Minor reformatting for better alignment with PolyORB version.
31442 Store the entity for the asynchronous flag of an RACW, rather than the
31443 expression, in the asynchronous flags table. This will allow this flag
31444 to be used in other subprograms beside Add_RACW_Read_Attribute.
31446 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31448 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

31452 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
31453 sockets constant MSG_NOSIGNAL (Linux-specific).
31454 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
31455 all Send operations.
31456 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
31457 from trigerring SIGPIPE.
31458 Rename components to avoid clash with Ada 2005 possible reserved
31460 (Check_Selector): When the select system call returns with an error
31461 condition, propagate Socket_Error to the caller.

31471 instead do this at freeze time (we won't do it if there is an address
31473 Change "pragma inline" to "pragma Inline" in information and error
31475 Minor reformatting.
31477 * freeze.adb (Check_Address_Clause): Remove previous change, not the
31478 right way of doing things after all.
31479 (Freeze_Entity): For object, set Is_Public for imported entities
31480 unless there is an address clause present.
31482 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
31484 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
31485 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
31486 ensures proper handling of types with rep clauses, which might have
31487 their TYPE_SIZE set already.
31489 2004-09-21 Robert Dewar <dewar@gnat.com>
31491 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
31492 packed array types in both little- and big-endian cases. This change
31493 ensures that we no longer count on the unused bits being initialized
31494 for such types (and in particular ensures that equality testing will
31495 only read the relevant bits).
31496 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31497 These changes mean that we no longer need to initialize small packed
31499 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
31500 optimization to an LJM field as to its parent field.
31502 * ada-tree.h, trans.c, utils.c, utils2.c:
31503 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31505 2004-09-20 Jan Hubicka <jh@suse.cz>
31507 * utils.c (gnat_finalize): Remove.
31508 (end_subprog_body): Directly call cgraph_finalize_function;
31509 do not lower the nested functions.
31511 2004-09-20 Robert Dewar <dewar@gnat.com>
31514 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
31515 if an address clause is present, since that means that the Import
31518 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
31520 * 5tsystem.ads: Removed, no longer used.
31522 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
31523 Zack Weinberg <zack@codesourcery.com>
31525 * ada-tree.def: Use tree_code_class enumeration constants
31526 instead of code letters.

31544 an existing directory.
31545 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
31546 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
31547 Convert the result to File_Size.
31549 * prj.ads: (Project_Error): New exception
31551 * prj-attr.adb: Except in procedure Initialize, Fail comes from
31552 Prj.Com, not from Osint.
31553 (Attrs, Package_Attributes): Tables moved to private part of spec
31554 (Add_Attribute, Add_Unknown_Package): Moved to new child package
31556 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
31557 Prj.Project_Error after call to Fail.
31558 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
31559 Fail. Check that package name is not already in use.
31561 * prj-attr.ads: Comment updates to indicate that all subprograms may be
31562 used by tools, not only by the project manager, and to indicate that
31563 exception Prj.Prj_Error may be raised in case of problem.
31564 (Add_Unknown_Package, Add_Attribute): Moved to new child package
31566 (Attrs, Package_Attributes): Table instantiations moved from the body to
31567 the private part to be accessible from Prj.Attr.PM body.
31569 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
31570 from new package Prj.Attr.PM.
31571 (Parse_Attribute_Declaration): Call Add_Attribute from new package
31574 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
31576 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
31577 instead of Elaboration_Checks).

31621 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
31622 pragmas recognized by GNAT.
31624 * gnat_rm.texi: Document pragma Detect_Blocking.
31626 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
31627 raise Program_Error if called from a protected operation.
31629 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
31630 the protected action nesting level.
31631 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
31632 protected action nesting level.
31633 (Unlock): When pragma Detect_Blocking is active decrease the protected
31634 action nesting level.
31636 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
31637 Protected_Action_Nesting.
31639 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31640 Common_ATCB record. It contains the dynamic level of protected action
31641 nesting for each task. It is needed for checking whether potentially
31642 blocking operations are called from protected operations.
31643 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31644 Detect_Blocking is active or not in the partition.
31646 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
31647 raise Program_Error if called from a protected operation.

31656 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
31657 raise Program_Error if called from a protected operation, and increase
31658 the protected action nesting level.
31659 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
31660 Program_Error if called from a protected operation, and increase the
31661 protected action nesting level.

31667 the protected action nesting level.
31668 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
31669 Program_Error if called from a protected operation, and increase the
31670 protected action nesting level.

31674 active, raise Program_Error if called from a protected operation.
31675 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
31676 protected action nesting level.
31678 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
31679 insertion of the statement raising Program_Error. The run time
31680 contains the required machinery for handling that.
31682 * sem_util.ads: Change comment associated to procedure
31683 Check_Potentially_Blocking_Operation.
31684 This procedure does not insert a call for raising the exception because
31685 that is currently done by the run time.
31687 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31689 * init.c: Add the global variable __gl_detect_blocking that indicates
31690 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31691 making the pragma available at run time.
31692 (__gnat_set_globals): Pass and update the detect_blocking parameter.
31694 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
31695 pragma Detect_Blocking is active.
31697 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
31699 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31700 DB is found in the ali file. Any unit compiled with pragma
31701 Detect_Blocking active forces its effect in the whole partition.
31703 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31704 Detect_Blocking is active and delay is called from a protected
31707 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
31708 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
31709 Detect_Blocking is active (0 otherwise).
31710 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
31711 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
31714 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
31716 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
31717 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
31720 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31721 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31722 Update API in placeholder implemetation of s-parint to reflect changes
31723 in distribution runtime library.
31725 * sem_ch3.adb (Expand_Derived_Record): Rename to
31726 Expand_Record_Extension.
31728 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31729 primitive operations of potentially distributed object types that have
31730 non-controlling anonymous access formals.
31732 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31734 New implementation of expansion for remote access-to-subprogram types,
31735 based on the RACW infrastructure.
31736 This version of sem_dist is compatible with PolyORB/DSA as well as
31739 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31740 Asynchrronous that applies to a remote access-to-subprogram type, mark
31741 the underlying RACW type as asynchronous.
31743 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31744 __gnat_using_gnu_linker to 1.
31746 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31747 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31748 GNAT.Perfect_Hash_Generators, and remove the empty

31753 * exp_ch3.adb (Expand_Derived_Record): Rename to
31754 Expand_Record_Extension.
31755 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31756 a component declaration must remain attached at that point in the
31757 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31758 It is therefore necessary to take a copy of the expression when building
31759 the corresponding assignment statement in the init proc.
31760 As a side effect, in the case of a derived record type, we now see the
31761 original expression, without any rewriting that could have occurred
31762 during expansion of the ancestor type's init proc, and we do not need
31763 to go back to Original_Node.
31765 * exp_ch3.ads (Expand_Derived_Record): Rename to
31766 Expand_Record_Extension.
31768 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
31769 Returns the RACW type used to implement a remote access-to-subprogram
31771 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31772 New subprograms. Used to create a proxy tagged object for a remote
31773 subprogram. The proxy object is used as the designated object
31774 for RAS values on the same partition (unless All_Calls_Remote applies).
31775 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31776 System.Partition_Interface.Get_Unique_Remote_Pointer.
31777 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31778 Renamed from Add_RAS_*_Attribute.
31779 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31781 New implementation of expansion for remote access-to-subprogram types,
31782 based on the RACW infrastructure.
31784 * exp_dist.ads (Copy_Specification): Update comment to note that this
31785 function can copy the specification from either a subprogram
31786 specification or an access-to-subprogram type definition.
31788 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31790 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31791 in an instance, between an explicit subprogram an one inherited from a
31792 type derived from an actual.
31794 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31795 add a polling call if the subprogram is to be inlined by the back-end,
31796 to avoid repeated calls with multiple inlinings.
31798 * checks.adb (Apply_Alignment_Check): If the expression in the address
31799 clause is a call whose name is not a static entity (e.g. a dispatching
31800 call), treat as dynamic.
31802 2004-09-09 Robert Dewar <dewar@gnat.com>
31804 * g-trasym.ads: Minor reformatting
31806 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31812 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
31815 2004-09-09 Pascal Obry <obry@gnat.com>
31817 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31818 enable map file generation. Add the right option to generate the map
31819 file if Map_File is set to True.
31821 * gnatdll.adb (Gen_Map_File): New variable.
31822 (Syntax): Add info about new -m (Map_File) option.
31823 (Parse_Command_Line): Add support for -m option.
31824 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.
31825 Minor reformatting.
31827 2004-09-09 Laurent Pautet <pautet@act-europe.fr>

32076 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
32077 discriminants that rename those of the parent, recover names of

32109 returning C.int, to avoid using a derived boolean type.
32111 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

32140 ignore overflows on low and high bounds of an index to also account for
32141 differences in signedness between sizetype and gnu_index_subtype.
32142 These are as legitimate as the ones caused by a lower TYPE_PRECISION

36059 complete assignment subtree which is now unnecessary, as the expansion
36060 of inlined call has been improved to preserve a consistent assignment
36061 tree. Note_Possible_Modification must be called only
36062 after checks have been applied, or else unnecessary checks will
36065 * sem_util.adb (Note_Possible_Modification): Reorganise the handling

36069 recorded as modifying the pointer);

36256 part has been scanned-out and it was present
36258 * par-ch3.adb, par-ch4.adb, par-ch6.adb: Give support to AI-231
36260 * sem_aggr.adb: (Check_Can_Never_Be_Null): New subprogram
36261 (Aggregate_Constraint_Checks): Generate conversion to the null-excluding
36262 type to force the corresponding run-time check
36263 (Resolve_Aggregate): Propagate the null-excluding attribute to the array
36265 (Resolve_Array_Aggregate): Carry out some static checks
36266 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
36268 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null
36269 attribute must be set only if specified by means of the null-excluding

36288 case of anonymous access types.
36289 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
36292 * sem_res.adb (Resolve_Actuals): Carry out some static check
36293 (Resolve_Null): Allow null in anonymous access
36295 * sinfo.adb: New subprogram Null_Exclusion_Present
36296 All_Present and Constant_Present available on access_definition nodes
36298 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
36299 object_declaration, derived_type_definition, component_definition,

36319 * sem_ch12.adb: Add comment for previous change
36321 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
36323 * osint.adb (Executable_Prefix): Set Exec_Name to the current
36324 executable name when not initialized. Otherwise, use its current value.
36326 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
36327 initialize it to another executable name than the current one. This
36328 allows to configure paths for an executable name (gnatmake) different
36329 from the current one (gnatdist).
36331 2004-03-29 Ed Schonberg <schonberg@gnat.com>
36333 * exp_ch6.adb (Expand_Call): A call to a function declared in the
36334 current unit cannot be inlined if it appears in the body of a withed
36335 unit, to avoid order of elaboration problems in gigi.
36337 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
36338 information for protected (wrapper) operation as well, to simplify gdb
36341 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
36342 protected body, indicate that the entity for the generated spec comes
36343 from source, to ensure that references are properly generated for it.
36344 (Build_Body_To_Inline): Do not inline a function that returns a
36347 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
36348 apply convention to homonyms that are declared explicitly.
36350 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
36351 that renames an equality operator and the operands are overloaded,
36352 resolve them with the declared formal types, before rewriting as an
36355 2004-03-29 GNAT Script <nobody@gnat.com>
36357 * Make-lang.in: Makefile automatically updated
36359 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
36361 * memtrack.adb: Log realloc calls, which are treated as free followed

36366 * prj-makr.adb (Process_Directories): Detect when a file contains
36367 several units. Do not include such files in the config pragmas or

36376 resolve links when computing the display names.
36378 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
36380 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
36381 attribute reference does not denote a subtype, it can be any
36382 expression that has a classwide type, potentially after an implicit
36383 dereference. In particular, the prefix can be a view conversion for
36384 a classwide type (for which Is_Object_Reference holds), but it can
36385 also be a value conversion for an access-to-classwide type. In the
36386 latter case, there is an implicit dereference, and the original node
36387 for the prefix does not verify Is_Object_Reference.
36389 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
36390 conversion of a discriminant-dependent component of a mutable object
36393 2004-03-25 Ed Schonberg <schonberg@gnat.com>
36395 * freeze.adb (Freeze_Entity): When an inherited subprogram is
36396 inherited, has convention C, and has unconstrained array parameters,
36397 place the corresponding warning on the derived type declaration rather
36398 than the original subprogram.
36400 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
36401 indication on renaming declaration, if formal has a box and actual
36404 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
36405 determine whether to generate an implicit or explicit reference to
36406 the renamed entity.
36408 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
36409 subprogram renaming comes from a defaulted formal subprogram in an
36412 2004-03-25 Gary Dismukes <dismukes@gnat.com>
36414 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
36415 value expressions to ensure that calls within a component definition
36416 will be checked (since those are evaluated during the record type's
36419 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>

36465 2004-03-22 Ed Schonberg <schonberg@gnat.com>
36467 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
36468 declaration for a child subprogram body that acts as a spec, indicate
36469 that the entity in the declaration needs debugging information.
36471 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
36472 full view if the subtype is created for a constrained record component;
36473 gigi has enough information to construct the record, and there is no
36474 place in the tree for the declaration.
36476 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
36477 serial number for the dummy body that is built for analysis, to avoid
36478 inconsistencies in the generation of internal names when compiling
36481 2004-03-22 Thomas Quinot <quinot@act-europe.fr>

36509 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
36510 gnat_ug_wnt.texi: Regenerate.
36512 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
36514 * ada-tree.h: Update copyright notice.
36515 Minor reformatting.
36517 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
36519 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
36520 as regular exception objects and not as mere integers representing the
36521 condition code. The latter approach required some dynamics to mask off
36522 severity bits, which did not fit well into the GCC table based model.
36523 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
36524 exception data objects. We don't it and it would conflict with the other
36525 external symbol we have to generate for such exceptions.
36527 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
36528 the special code for VMS exceptions, since these are now represented
36529 as regular exceptions objects.
36531 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36533 * decl.c (debug_no_type_hash): Remove.
36534 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
36535 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
36537 2004-03-19 Laurent Guerby <laurent@guerby.net>
36539 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
36540 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
36542 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
36544 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
36545 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
36546 (TYPE_RM_SIZE_INT): Directly use type.values.
36547 (TREE_LOOP_ID): Clean up check.
36548 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
36549 TYPE_VALUES, not TYPE_FIELDS.
36550 * trans.c (convert_with_check): Delay access of bounds of basetype
36551 until sure is numeric.
36553 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>
36555 * 5atpopsp.adb: Remove RTEMS from list of platforms using this file.
36558 * 5ataprop.adb, 5ftaprop.adb, 5htaprop.adb, 5itaprop.adb, 5staprop.adb,
36559 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
36560 Specific.Set instead of direct call to e.g pthread_setspecific.
36562 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
36564 * adaint.c: Update comments.
36566 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
36567 GNATLIB_SHARED for FreeBSD.
36569 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
36571 * init.c [VxWorks]: Do not fix the stack size for the environment task.
36572 When needed (stack checking) the stack size is retrieved
36573 from the VxWorks kernel.
36575 * Makefile.in: Flag -nostdinc is required when building the run time
36576 for avoiding looking for files in the base compiler.
36577 Add the VxWorks specific version of the package body for
36578 System.Stack_checking.Operations (5zstchop.adb).
36580 * Make-lang.in: Add the object file for
36581 System.Stack_Checking.Operations.
36583 * Makefile.rtl: Add object file for the package
36584 System.Stack_Checking.Operations.
36586 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
36588 * s-stache.ads, s-stache.adb: Move the operations related to stack
36589 checking from this package to package System.Stack_Checking.Operations.
36590 This way, stack checking operations are only linked in the final
36591 executable when using the -fstack-check flag.
36593 2004-03-18 Doug Rupp <rupp@gnat.com>
36595 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
36598 * 5qsystem.ads, 5xcrtl.ads: New files.

36604 * prj-env.adb (Source_Paths, Object_Paths): New tables.
36605 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
36606 the procedures Add_To_Path_File.
36607 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
36608 making sure that each directory is present only once and, for object
36609 dirs, when a directory already present is added, the duplicate is
36610 removed and the directory is always put as the last in the table.
36611 Write the path files at the end of these accumulations.
36613 * prj-nmsc.adb (Record_Source): Add source file name in hash table
36614 Files_Htable for all sources.
36616 * prj-proc.adb (Process): Remove restrictions between not directly
36617 related extending projects.
36619 2004-03-18 Emmanuel Briot <briot@act-europe.fr>

36625 parameter Trusted_Mode.
36627 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
36629 * scn.adb (Determine_License): Take into account a degenerated case
36630 when the source contains only comments.
36632 2004-03-18 Ed Schonberg <schonberg@gnat.com>
36634 * sem_warn.adb (Check_References): For a warning on a selected
36635 component that does not come from source, locate an uninitialized
36636 component of the record type to produce a more precise error message.
36638 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
36640 * 3zsoccon.ads: Fix multicast options.
36642 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
36645 2004-03-15 Robert Dewar <dewar@gnat.com>
36647 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
36648 pragma used for a private type.
36650 * lib-xref.adb (Generate_Reference): Do not generate warning if
36651 reference is in a different unit from the pragma Unreferenced.
36653 * 5vtpopde.adb: Minor reformatting
36654 Fix casing of To_Task_ID
36656 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
36657 flag if we have an unchecked conversion to an access type in the same
36660 2004-03-15 Geert Bosch <bosch@gnat.com>
36662 * a-ngcoty.adb (Modulus): In alternate formula for large real or
36663 imaginary parts, use Double precision throughout.
36665 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36666 we want to be able to compile run-time with -gnata for testing, but
36667 this may also be instantiated in user code that is compiled with -gnata.
36669 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
36671 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
36672 codes. Having a separate type for this is useful to enforce consistency
36673 throughout the various run-time units.
36674 (Exception_Data): Use Exception_Code for Import_Code.
36676 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
36677 Natural and Integer in various places.
36678 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
36679 with the severity bits masked off.
36680 (Register_VMS_Exception): Handle the additional exception data pointer
36683 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
36684 component, now reflected by an exported accessor.
36685 (is_handled_by): New routine to compute whether the propagated
36686 occurrence matches some handler choice specification. Extracted out of
36687 get_action_description_for, and expanded to take care of the VMS
36689 (get_action_description_for): Use is_handled_by instead of an explicit
36690 complex condition to decide if the current choice at hand catches the
36691 propagated occurrence.
36693 * raise.h (Exception_Code): New type for C.
36695 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
36696 System.Standard_Library.Exception_Code, to allow references from the
36697 pragma import/export expander.
36699 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
36700 New accessors to allow easy access to GNAT exception data
36702 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
36703 redundant Handled_By_Others component, helper for the personality
36704 routine which will now be able to call the appropriate exception data
36707 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36708 component of Standard_Exception_Type to be the closest possible to
36709 Exception_Code in System.Standard_Library, that we cannot get at this
36710 point. Expand a ??? comment to notify that this type node should
36711 probably be rewritten later on.
36713 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36714 registration call to include a pointer to the exception object in the
36717 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36718 instead of int and explicit bitmasks.
36720 2004-03-15 Vincent Celier <celier@gnat.com>
36722 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36723 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36725 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36726 longer needed now that it is in the spec of
36727 System.Tasking.Task_Attributes.
36729 * adaint.h, adaint.c: (__gnat_create_output_file): New function
36731 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
36733 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36735 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36736 taken care of in Scan_Make_Arg.
36737 (Scan_Make_Arg): Add the executable suffix only if the argument
36738 following -o, in canonical case, does not end with the executable
36739 suffix. When in verbose mode and executable file name does not end
36740 with executable suffix, output the executable name, in canonical case.

37713 checks for bitfield creation are triggered.
37714 (finish_record_type): During last pass over the fields, clear
37715 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

38057 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity

38174 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
38175 N_String_Literal node always references an E_String_Literal_Subtype
38176 entity. This may not be true in the future.
38177 (Possible_Bit_Aligned_Component): Move processing of
38178 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
38180 * exp_ch6.adb (Expand_Thread_Body): Pick up

38185 (Type_May_Have_Bit_Aligned_Components): New function.

38225 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
38226 ineffective elaborate all pragmas on non-visible packages (this
38227 happened when a renamed subprogram was called). Now the elaborate all
38228 always goes on the package containing the renaming rather than the one
38229 containing the renamed subprogram.
38231 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
38232 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

38258 -B is specified. Fail when there are only foreign mains in attribute

38293 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
38294 all attributes, including read-only attribute.

38333 checked when limited aggregates are implemented.

38336 pure, emit warning.

38453 Created and exported __gnat_map_signal to support signal -> exception
38454 mapping that is dependent on the VxWorks version.

38487 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
38488 bounds of a loop, create a separate block in order to generate proper
38489 cleanup actions to prevent memory leaks.
38491 * sem_res.adb (Resolve_Call): After a call to
38492 Establish_Transient_Scope, the call may be rewritten and relocated, in

38511 2003-12-08 Robert Dewar <dewar@gnat.com>
38513 * 7sintman.adb: Minor reformatting
38515 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
38516 standard linker options to get standard libraries linked. We now plan
38517 to provide dummy versions of these libraries to match the appropriate
38518 configurable run-time (e.g. if a library is not needed at all, provide
38519 a dummy empty library).
38521 * targparm.ads: Configurable_Run_Time mode no longer affects linker
38522 options (-L parameters and standard libraries). What we plan to do is
38523 to provide dummy libraries where the libraries are not required.
38525 * gnatbind.adb: Minor comment improvement
38527 2003-12-08 Javier Miranda <miranda@gnat.com>
38529 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded

38533 default initialized components.
38534 (Gen_Assign): In case of default-initialized component, generate a
38535 call to the IP subprogram associated with the component.

38537 of aggregate with default initialized components.
38538 (Has_Default_Init_Comps): Improve implementation to recursively check
38539 all the present expressions.
38541 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
38542 to indicate that the initialization call corresponds to a
38543 default-initialized component of an aggregate.
38544 In case of default initialized aggregate with tasks this parameter is
38545 used to generate a null string (this is just a workaround that must be
38546 improved later). In case of discriminants, this parameter is used to
38547 generate a selected component node that gives access to the discriminant
38550 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
38551 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
38552 allocated aggregates with default-initialized components.
38554 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
38555 the box notation is used in positional aggregates.

38597 Process nodes N_Comment.
38599 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
38600 without comments and there are some comments, set the flag
38601 Unkept_Comments to True.
38602 (Scan): If there are comments, set the flag Unkept_Comments to True and
38603 clear the comments.
38604 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
38605 (Next_End_Nodes: New table

38633 Comment_Id and set Token to Tok_Comment when scanning a comment.
38634 (Set_Comment_As_Token): New procedure
38636 * sinput-p.adb: Update Copyright notice
38637 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

38642 * sem_aggr.adb: Add dependence on Exp_Tss package
38643 Correct typo in comment
38644 (Resolve_Aggregate): In case of array aggregates set the estimated
38645 type of the aggregate before calling resolve. This is needed to know
38646 the name of the corresponding IP in case of limited array aggregates.
38647 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
38648 in case of default initialized array components.
38650 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

38670 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
38671 they are automatically generated by Make-lang.in and cause nothing but
38672 maintenance troubles.
38674 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
38676 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

38690 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
38691 to ensure that the kernel fills in the interrupted context structure
38692 before calling a signal handler, which is necessary to be able to
38693 unwind past it. Update the copyright notice.
38695 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
38697 * a-elchha.ads: New file.
38699 * a-elchha.adb: New default last chance handler. Contents taken from
38700 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
38702 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
38703 is moved to a-elchha.adb to provide a target-independent default last

38781 redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
38782 included in HIE_NONE_TARGET_PAIRS.
38784 2003-12-03 Ed Schonberg <schonberg@gnat.com>
38787 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
38788 is legal in an instance, because legality is cheched in the template.
38791 (Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
38792 appplied to an unchecked conversion of a formal parameter.
38795 (Output_Unreferenced_Messages): Suppress "not read" warnings on imported

38804 Update the documentation, and deal properly with sizeof (REG) different
38805 from sizeof (void*).

38809 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
38810 so that the debugger can reliably access the value of the parameter,
38811 and therefore is able to display the exception name when an exception
38812 breakpoint is reached.
38814 2003-12-01 Thomas Quinot <quinot@act-europe.fr>
38816 * fmap.adb: Fix typo in warning message.

38828 2003-12-01 Ed Schonberg <schonberg@gnat.com>
38830 * exp_ch6.adb (Expand_Actuals): When applying validity checks to

38869 2003-11-26 Arnaud Charlet <charlet@act-europe.fr>
38871 (Cond_Timed_Wait): Introduce new constant Time_Out_Max,
38872 since NT 4 cannot handle timeout values that are too large,
38873 e.g. DWORD'Last - 1.
38875 2003-11-26 Ed Schonberg <schonberg@gnat.com>
38878 (Expand_N_Slice): Recognize all cases of slices that appear as actuals

40077 (Freeze_Array_Type): We do not need an initialization routine for types
40078 derived from String or Wide_String. They should be treated the same
40079 as String and Wide_String themselves. This caused problems with the
40080 use of Initialize_Scalars.
40083 (Expand_Assign_Record): Do component-wise assignment of non-byte aligned
40084 composites. This allows use of component clauses that are not byte

40151 Remove the test against being in No_Run_Time_Mode before generating a
40152 call to Register_Tag. It is redundant with the test against the
40153 availability of the function Register_Tag.
40155 2003-10-24 Vincent Celier <celier@gnat.com>

40169 information, check that the source exists and, if it does, that the path
40170 is the actual path of a source of a project.

40223 External_Tag attribute definition clauses.
40225 2003-10-23 Ed Schonberg <schonberg@gnat.com>
40228 * exp_dbug.adb (Debug_Renaming_Declaration): For the renaming of a
40229 child unit, generate a fully qualified name to avoid spurious errors

42360 (general) Add @./@: where approriate, and two spaces after the
42361 full stop at the end of a sentence. Use @samp markup when
42362 referring concrete lexical entities (keywords, attribute names
42363 etc.), and @syntax for ARM grammar elements. Use @r for English

42379 function approach did not work well because of a side effect (the
42380 function call could reallocate the table which was being indexed
42381 using its result). Fixes ada/4851.

42442 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
42443 need to force universal inlining for these cases.
42445 2001-12-19 Arnaud Charlet <charlet@gnat.com>
42447 * s-taprob.adb: Minor clean ups so that this unit can be used in

42474 the argument of an initialization procedure.
42476 * trans.c (tree_transform, case of arithmetic operators): If result
42477 type is private, the gnu_type is the base type of the full view,
42478 given that the full view itself may be a subtype.
42480 2001-12-17 Robert Dewar <dewar@gnat.com>
42482 * sem_res.adb: Minor reformatting

42748 2001-12-17 Laurent Pautet <pautet@gnat.com>
42751 Fix comment of Shutdown_Socket and Close_Socket. These functions
42752 should not fail silently because if they are called twice, this
42753 probably means that there is a race condition in the user program.
42754 Anyway, this behaviour is consistent with the rest of this unit.

44091 (Time_Stamp_Mismatch): use CRC_Match for comparison.
44092 (Set_Source_Table): idem.
44095 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
44096 instead of simple checksum.
44097 (CRC_Match): new function.
44098 (CRC_Error): new constant.
44100 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
44101 a CRC now and not a simple checksum. A CRC uses lower-case hex
44102 letters, fixes ambiguity in parsing.
44104 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
44105 is what this variable will store.
44107 * bcheck.adb: Change reference to chechsum in comments by CRC.
44108 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
44109 rename All_Checksum_Match to All_CRC_Match. Change due to API
44110 renaming since now GNAT does not use a simple checksum but a
44111 CRC using GNAT.CRC32.
44113 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
44114 now and not anymore a simple checksum.
44116 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many

44142 (Load_File): fix initialization of S (change Source_Checksum to
44145 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
44146 Source_CRC in S initialization.

44151 Update comments for the CRC.
44153 * types.adb (Hex): Use lowercase for the letter part.
44155 * types.ads (Get_Hex_String): Returns the hexadecimal representation
44156 for a word. This is currently used only for CRC. In previous version,
44157 the checksum was using a representation with all letter being
44158 upper-case. With the new implementation (using CRC) we do not remove
44159 the 32th bit of the CRC, so we can have an upper-case starting letter
44160 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
44161 It is ambigous since the CRC was optional and could be followed by
44162 options like EB, EE. So now this routines uses lower-case letter for
44163 the hexadecimal representation. Strange enough only lower case letters
44164 where checked in Scan_ALI (even if this was not a possible case).
44166 * gnatvsn.ads (Library_Version): changed to 3.15a.
44168 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
44171 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
44174 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
44175 Add 2001 to copyright notice
44176 (Accumulate_Checksum): Modify to use System.CRC32.
44178 * ali-util.ads: Redo changes of previous revision to continue to use
44179 the word Checksum. Add 2001 to copyright notice.
44181 * ali.adb: Undo some of previous changes, not needed.
44182 Keep the change for lower case letters in the checksum.
44184 * ali.ads: Undo previous change not needed.
44186 * bcheck.adb: Undo most of previous change, not needed.
44187 But do use Checksums_Match for checksum comparison.
44189 * gnatls.adb: Undo most of previous change, not needed.
44190 But do use Checksums_Match for comparing checksums.
44192 * lib-load.adb: Undo previous change, not needed.
44194 * lib-writ.adb: Undo previous change, not needed.
44196 * lib-writ.ads: Document that checksums use lower case,

44212 * sinput-p.adb: Undo previous change, not needed.
44214 * sinput.adb: Undo previous change, not needed.
44216 * sinput-l.adb: Undo previous change, not needed.
44218 * sinput.ads: Undo previous change, not needed. Keep only comment
44219 on new checksum algorithm
44221 * Makefile.in: Add s-crc32 as needed, remove g-crc32.
44222 Also remove a-tags and a-stream from GNAT sources.
44224 * ali.adb (Scan_ALI): fix typo introduce in latest check-in.
44226 * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
