2956 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2957 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2958 N_Identifier. This was interfering with other cases that are rewritten
2959 as N_Identifier, such as allocators, resulting in passing of the wrong

2961 longer needed at all.

5131 * sem_util.ads, sem_util.adb
5132 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
5133 Is_Remote_Call_Interface to identify RACW types in a stable and
5134 consistent way. We used to rely in this predicate on the privateness of
5135 the designated type and its ancestors, but depending on the currently
5136 visible private parts, this caused false negatives. We now uniformly
5137 rely on checks made at the point where the RACW type is declared.
5138 (Inspect_Deferred_Constant_Completion): Moved from Sem_Ch7.

5145 (Analyze_Object_Declaration): Fix over-conservative condition
5146 restricting use of predefined assignment with tagged types that have
5148 (Analyze_Object_Declaration): Relax the check regarding deferred
5149 constants declared in scopes other than packages since they can be
5150 completed with pragma Import.
5151 Add missing escaping of all-caps word 'CPP' in error messages.
5152 (Build_Discriminated_Subtype): Do not inherit representation clauses
5153 from parent type if subtype already carries them, because they are
5154 inherited earlier during derivation and already include those that may
5155 come from a partial view.
5157 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
5158 Check the declarations of a subprogram body for proper deferred
5159 constant completion.

5169 F is a parameterless function that returns an array, and S is a subtype
5171 (Analyze_Call): Insert dereference when the prefix is a parameterless
5172 function that returns an access to subprogram and the call has
5174 Reject a non-overloaded call whose name resolves to denote
5175 a primitive operation of the stub type generated to support a remote
5176 access-to-class-wide type.
5178 2008-05-20 Ed Schonberg <schonberg@adacore.com>

5192 (Add_One_Interp): Ignore any interpretation that is a primitive
5193 operation of an RACW stub type (these primitives are only executed
5194 through dispatching, never through static calls).
5195 (Collect_Interps): When only one interpretation has been found, set N's
5196 Entity and Etype to that interpretation, otherwise Entity and Etype may
5197 still refer to an interpretation that was ignored by Add_One_Interp,
5198 in which case would end up with being marked as not overloaded but with
5199 an Entity attribute not pointing to its (unique) correct interpretation.
5201 2008-05-20 Ed Schonberg <schonberg@adacore.com>
5204 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

5214 (Print_Itype): Do not modify the sloc of the component type of a
5215 (packed) array itype, because it is an unrelated type whose source
5216 location is independent of the point of creation of the itype itself.
5218 2008-05-20 Thomas Quinot <quinot@adacore.com>
5220 * uintp.adb, urealp.adb: Replace calls to Increment_Last + Set with

5252 => null". Add clarifying ".all", even though implicit .all is legal
5255 2008-05-20 Arnaud Charlet <charlet@adacore.com>

5258 equivalent representation, but has the advantage of allowing
5259 compilation of this file under 64 bits platforms.
5261 * s-os_lib.adb (Normalize_Pathname): Mark Cur_Dir constant.
5263 * s-osinte-irix.ads: (Alternate_Stack_Size): Add dummy declaration.

9324 clauses for inherited components of a type extension.
9325 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for

9503 (Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
9505 (Derive_Subprograms): Handle derivations of predefined primitives
9506 after all the user-defined primitives to ensure that they are
9507 found in proper order in instantiations.

9509 of Related_Interface to Related_Type.
9510 (Record_Type_Declaration): Minor reordering of calls to decorate the

9512 before setting its Is_Tag attribute.
9513 (Analyze_Subtype_Declaration): In the case of subtypes with
9514 Private_Kind, inherit Known_To_Have_Preelab_Init from the parent.

9519 * sem_ch4.adb (Analyze_Selected_Component): Include the requeue
9520 statement to the list of contexts where a selected component with a
9521 concurrent tagged type prefix should yield a primitive operation.
9522 (Find_Primitive_Operation): Handle case of class-wide types.
9523 (Analyze_Overloaded_Selected_Component): If type of prefix is
9524 class-wide, use visible components of base type.
9525 (Resolve_Selected_Component): Ditto.
9526 (Try_Primitive_Operation, Collect_Generic_Type_Ops): If the type is a
9527 formal of a generic subprogram. find candidate interpretations by
9528 scanning the list of generic formal declarations.:
9529 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
9530 type from a limited_with_clause, and the full view is available, use it
9531 for subsequent semantic checks.
9532 (Check_Misspelled_Selector): Use Namet.Sp.Is_Bad_Spelling_Of function
9533 (Find_Primitive_Operation): New function.

9537 (Analyze_Selected_Component): Reorder local variables. Minot comment and
9538 code reformatting. When the type of the prefix is tagged concurrent, a

9566 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
9567 Timed_Entry_Call): Analyze the triggering statement as the first step of

9571 replicated some of the select statements. In case the Expander is
9572 disabled, perform regular analysis.
9573 (Check_Triggering_Statement): New routine.
9574 (Analyze_Requeue): Exclude any interpretations that are not entries when
9575 checking overloaded names in a requeue. Also test type conformance for
9576 matching interpretations rather than requiring subtype conformance at
9577 that point to conform with the RM's resolution rule for requeues.

10028 * trans.c (call_to_gnu): Always set the source location on the call
10029 expression. If the function returns-by-target, also set it on the
10030 address expression.

10165 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
10167 (Xref_Record): Change type for Line, since in the case of a reference to
10168 a predefined entity (as happens for array index types), the line is set
10170 Add support for parsing multiple array index types info, or
10171 multiple inherited interfaces info. This information cannot be stored
10172 in Xref_Entity_Record, which only supports a single instance of Tref_*,
10173 and is therefore stored in the list of references instead. It has a
10174 special treatement later on in tools that use this information.

10188 Dismukes). After this patch there is no need to perform any
10189 additional management on these nodes in Expand_Interface_Actuals.
10191 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
10192 that handles use of 'Access and 'Unchecked_Access applied to
10193 actuals covering interface types. Such code is now
10194 centralized in Expand_N_Attribute_Reference.
10196 2007-10-15 Ed Schonberg <schonberg@adacore.com>
10198 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
10199 of tagged types whose ultimate ancestor is a CPP type.

10224 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
10225 the generic Heap_Sort_G, in order to avoid trampolines.
10227 2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>

10238 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
10239 used by VxWorks targets to have access to task-specific data and be
10240 able to extract the stack boundaries for stack checking.
10241 Use system-vms-ia64.ads on ivms.
10243 * Make-lang.in: Update dependencies.
10245 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

10284 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
10285 association for an access component, add an association with null as
10286 the expression. Remove testing for array subtypes and the setting in
10287 that case of Ctyp to the array component type, which prevented proper
10288 inclusion of an association for null-initialized arrays. Collapse
10289 condition that tests for array subtypes into just a test of
10290 Is_Partially_Initialized_Type (which already covers arrays anyway).

10307 * sem_ch4.adb: Minor code and comment reformatting.
10308 (Analyze_Allocator): When the designated type of an unconstrained
10309 allocator is a record with unknown discriminants or an array with
10310 unknown range bounds, emit a detailed error message depending on the
10311 compilation mode and whether the designated type is limited.

10476 Add a section on leap seconds control along with two entities used to
10477 enable and disable leap seconds support. The array Leap_Second_Times is

10512 2007-09-26 Olivier Hainque <hainque@adacore.com>
10514 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
10515 #include <utime.h> and #define GCC_RESOURCE_H before
10516 #include <sys/wait.h>.
10517 Add more protections in __gnat_translate_vms.
10519 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before
10520 #include <sys/wait.h>.
10522 2007-09-26 Thomas Quinot <quinot@adacore.com>
10523 Sergey Rybin <rybin@adacore.com>
10525 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
10527 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
10530 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
10532 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
10535 * sem_dist.ads: Minor comment fix
10537 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
10539 2007-09-26 Javier Miranda <miranda@adacore.com>
10540 Eric Botcazou <ebotcazou@adacore.com>
10543 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
10544 indirection added to the HT_Link component of the TSD. This is required
10545 to statically allocate the TSD.
10548 Minor reordering of the declarations in the private part. Required to
10549 add a level of indirection to the contents of the TSD component HT_Link.
10550 This is required to statically allocate the TSD.
10552 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
10553 Is_Statically_Allocated set from constant objects.
10554 Do not make exported constants created by the compiler volatile.
10555 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
10558 * trans.c (Identifier_to_gnu): For constants, unshare initializers
10559 before returning them.
10561 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
10562 public part of the package.
10563 (Make_DT): Move HT_Link component out of the TSD record. For this
10564 purpose Make_DT now declares a separate object that stores the
10565 HT_Link value, and initializes the TSD component with the address
10566 of this new object. The addition of this level of indirection is
10567 required to statically allocate the TSD because the TSD cannot
10568 have variable components.
10569 (Expand_Interface_Conversion): Improve the expanded code.
10570 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
10572 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
10573 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
10574 if we are building static dispatch tables then we must not generate
10575 extra code to register the primitive because the dispatch table will
10576 be built at the end of the library package; otherwise we notify that
10577 we cannot build the static dispatch table.
10579 2007-09-26 Robert Dewar <dewar@adacore.com>
10581 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
10584 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
10585 (Analyze_Record_Representation_Clause): Suppress junk warning for
10586 missing component clause.
10587 (Analyze_Attribute_Definition_Clause, case Address): Apply the special
10588 tests for controlled type overlay to composites with controlled
10590 (Analyze_Record_Representation_Clause): Add reference for component name
10592 2007-09-26 Javier Miranda <miranda@adacore.com>
10593 Gary Dismukes <dismukes@adacore.com>
10595 * einfo.adb (Is_Thunk): New attribute applicable to subprograms. True
10596 for thunks associated with interface types.
10598 * einfo.ads: Improve documentatation of Is_Internal
10599 (Is_Thunk): New attribute applicable to subprograms. True for thunks
10600 associated with interface types.
10601 Extensive comment fixes regarding flags that appear in all entities. The
10602 documentation is now consistent for all such flags (there were a number
10603 of errors in the documentation in this regard).
10605 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
10607 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
10608 of these procedures are passed a function call that already has
10609 build-in-place actuals (testing new flag
10610 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
10611 the case where processing continues.
10612 (Expand_Call): If the call is generated from a thunk body then we
10613 propagate the extra actuals associated with the accessibility
10614 level of the access type actuals.
10616 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
10617 of each extra formal of a protected operation to reference the
10618 corresponding extra formal of the subprogram denoted by the
10619 operation's Protected_Body_Subprogram.
10621 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
10622 N_Function_Call nodes.
10624 2007-09-26 Robert Dewar <dewar@adacore.com>
10626 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
10628 * debug.adb: Add d.s flag.
10630 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10632 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
10633 debug variable so that it won't be initialized when pragma
10634 Initialize_Scalars is in effect.
10636 2007-09-26 Gary Dismukes <dismukes@adacore.com>
10638 * freeze.adb (Freeze_Entity): Remove check for preelaborable
10639 initialization of a full view. This is moved to
10640 Analyze_Package_Specification.
10642 * sem_ch7.adb (Analyze_Package_Specification): Add check for
10643 preelaborable initialization of a full view in entity loop.
10644 (Uninstall_Declarations): If entity is a use-visible compilation unit,
10645 its child units are use-visible only if they are visible child units.
10647 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
10648 whether an expression can be used within a type declaration that
10649 requires preelaborable init.
10650 (Check_Components): Replace inline code that does partial checking for
10651 preelaborable default expressions with call to
10652 Is_Preelaborable_Expression.
10653 (Has_Preelaborable_Initialization): In the case of a generic actual
10654 subtype, (that is, Is_Generic_Actual is True), return the result of
10655 applying Has_Preelaborable_Initialization to the generic actual's base
10658 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
10660 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
10661 call to Jan_1_Day _Of_Week to optimize its performance.
10662 (Is_Leap): Move the routine to the scope of Week_In_Year.
10663 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
10664 weekday on which January 1 falls of Year - 1 and Year + 1. This function
10665 avoids calling Time_Of and Split, thus making it more efficent.
10666 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
10668 * g-calend.ads (Week_In_Year): Change comment to reflect new
10671 2007-09-26 Emmanuel Briot <briot@adacore.com>
10673 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
10674 Command_Line): New types
10675 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
10676 support for defining how switches can be grouped on a command line (as
10677 is the case for -gnatw... for GNAT), and how simple switches can be
10678 used as aliases for more complex switches (-gnatwa is same as
10680 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
10681 (Start, Current_*): New subprograms
10682 Added support for parsing an array of strings in addition to the real
10684 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
10685 be moved from the body to the private part of the spec.
10686 (*): All subprograms now have an extra parameter with default value to
10687 specify which parser should be used. For backward compatibility, it
10688 defaults to parsing the command line of the application. They were also
10689 modified to properly handle cases where each of the argument does not
10690 start at index 1 (which is always true for Ada.Command_Line, but not
10691 when processing any Argument_List).
10692 (Free): New subprogram
10693 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
10694 Argument): New subprograms
10695 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
10696 special characters like ':', '=',... are now handled in a single place,
10697 which makes the code more extensible eventually.
10698 (Getopt, Full_Switch): When the switch was returned as part of the
10699 special character '*', make sure it is prepended by the switch character
10700 ('-' in general), so that the application knows whether "foo" or "-foo"
10701 was specified on the command line.
10703 2007-09-26 Florian Villoing <villoing@adacore.com>
10705 * g-dirope.adb (Remove_Dir): In case we are removing directories
10706 recursively, make sure that if an exception is raised during the
10707 processing, the current working directory is reset to its initial
10708 value before propagating the exception.
10710 2007-09-26 Vincent Celier <celier@adacore.com>
10712 * gnatbind.adb: If there are several ALI files specified and there is
10713 a main program to bind, the first ALI is expected to contain the main
10714 subprogram and the names of the binder generated files will be derived
10715 from the first ALI file name.
10716 (Gnatbind): Fix insertion character in invocation of Error_Msg
10718 2007-09-26 Vincent Celier <celier@adacore.com>
10720 * gnatcmd.adb (Check_Files): Do not include sources that have been
10721 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
10723 2007-09-26 Ed Schonberg <schonberg@adacore.com>
10725 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
10726 information about each of its index types, following the type
10727 reference for its component type.
10729 2007-09-26 Vincent Celier <celier@adacore.com>
10731 * make.adb: (Kill): New procedure (__gnat_kill imported)
10732 (Running_Compile, Outstanding_Compiles): Global variables that
10733 were previously local to procedure Compile_Sources.
10734 (Sigint_Intercepted): Send signal SIGINT to all outstanding
10735 compilation processes.
10737 (Gnatmake): If project files are used, create the mapping of all the
10738 sources, so that the correct paths will be found.
10740 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
10742 2007-09-26 Vincent Celier <celier@adacore.com>

10753 * prj-attr.adb: New attributes Required_Switches (<language>) in
10754 packages Compiler and Binder.
10756 * prj-nmsc.adb: Major rewrite of the processing of configuration
10757 attributes for gprbuild. No impact on GNAT tools.
10759 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
10760 process configuration attributes: this is done in Prj.Nmsc.Check.
10761 (Recursive_Process): Make a full copy of packages inherited from project
10762 being extended, instead of a shallow copy.
10763 (Process_Project_Tree_Phase_1): New procedure
10764 (Process_Project_Tree_Phase_1): New procedure
10765 (Process): Implementation now uses the two new procedures
10767 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
10768 from the project config, not the tree config that no longer exists.

10794 ancestor of the derived type, the operations are inherited from the
10795 primary dispatch table of the parent.
10796 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
10797 when the context is an explicit type conversion.

11094 Thomas Quinot <quinot@adacore.com>
11096 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
11097 create an abstract subprogram in the case of 'Input. For 'Output we now
11098 create a real spec/body when the type is abstract, since it can
11099 potentially be called.
11100 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
11101 body for 'Output when the type is abstract (only the creation of the
11102 body for 'Input is excluded when the type is abstract).
11103 (Stream_Operation_OK): Add an additional condition in the return
11104 statement, so that False will be returned for TTS_Stream_Input if the
11105 associated tagged type is an abstract extension. Add comments for
11107 (Expand_N_Object_Declaration): For the case of a shared passive
11108 variable, insert init proc call only after the shared variable
11109 procedures have been processed, because the IP call needs to undergo
11110 shared passive variable reference expansion, which requires these
11111 procedures to be available (and elaborated).
11113 2007-09-10 Vincent Celier <celier@adacore.com>

11120 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
11121 given a box association, the type of the component is discriminated,
11122 and the value of the discriminant is the discriminant of the enclosing
11123 type, retrieve its value from the aggregate itself, where it must have
11126 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
11127 to remove other spurious ambiguities on arithmetic operations involving
11128 literals and addresses, on systems where Address is a visible integer
11129 type, when the operator is called in functional notation.
11130 (Try_Primitive_Operation): Within an instance, a call in prefixed form
11131 is legal when the types match, even if the operation is currently
11134 2007-09-10 Ed Schonberg <schonberg@adacore.com>
11136 * sem_ch12.adb (Build_Local_Package): A formal package with no
11137 associations is legal if all formals have defaults. It is not
11138 equivalent to a formal declared with a box.
11140 2007-09-10 Sergey Rybin <rybin@adacore.com>

11166 a debug renaming declaration specially.
11168 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
11170 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
11171 which a constant renaming is treated as a normal object declaration.
11172 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
11173 the N_Indexed_Component case.
11174 <N_Indexed_Component>: Fall through to above case.

11180 try again to get an integral mode for it.
11182 2007-09-07 Eric Botcazou <ebotcazou@adacore.com>
11184 Re-apply accidentally reverted change:
11186 2007-02-07 Andreas Krebbel <krebbel1@de.ibm.com>

11189 get_action_description_for): Replace _Unwind_Word with _uleb128_t
11190 and _Unwind_SWord with _sleb128_t.
11192 2007-09-06 Eric Botcazou <ebotcazou@adacore.com>
11194 * trans.c (convert_with_check): Update call to real_2expN.
11196 2007-09-05 Sandra Loosemore <sandra@codesourcery.com>
11198 * trans.c (Compilation_unit_to_gnu): Use set_cfun.

11255 (Is_Raised, Set_Is_Raised): Bodies of new routines.
11256 (Write_Entity_Flags): Write the status of flag Is_Raised.
11257 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
11258 spurious ambiguities when integer literals appear in the context of an
11259 address type that is a visible integer type.
11261 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
11262 exceptions never being raised.
11263 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

11274 initialization aggregate for the type, generate itype references for
11275 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
11277 2007-08-31 Gary Dismukes <dismukes@adacore.com>
11279 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
11280 library-level package renaming, pass the declaration associated with
11281 the renaming's special debug variable to Qualify_Entity_Names to ensure
11282 that its encoded name is properly qualified.
11284 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
11285 occurring in the list of entities to qualify, and do not attempt to
11286 traverse an entity list in that case. Variables associated with
11287 ` library-level package renamings can now occur in the table.

11297 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
11299 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
11302 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
11303 simple redundant qualifications. The check is performed whenever the

11311 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
11312 concatenations of string literals into a single literal, in order to
11313 avoid very deep recursion in the front end, which was causing stack
11316 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
11317 string, and the right operand is a string literal (the case of "" &
11318 "..."), optimize by avoiding copying the right operand -- just use the
11319 value of the right operand directly.
11321 * stringt.adb (Store_String_Chars): Optimize by growing the
11322 String_Chars table all at once, rather than appending characters one by
11324 (Write_String_Table_Entry): If the string to be printed is very long,
11325 just print the first few characters, followed by the length. Otherwise,
11326 doing "pn(n)" in the debugger can take an extremely long time.
11328 * sem_prag.adb (Process_Interface_Name): Replace loop doing
11329 Store_String_Char with Store_String_Chars.

11344 have not been fully analyzed.
11346 2007-08-31 Ed Schonberg <schonberg@adacore.com>
11348 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
11349 flag, for effiency. It is called when analyzing arithmetic operators
11350 and also for actuals in calls that are universal_integers. The flag is
11351 set for the predefined type address, and for any type or subtype
11354 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
11355 Universal_Integer, when the formal is a descendent of address and the
11356 call appears in user code.
11357 (Analyze_Selected_Component): if the prefix is a private extension, the
11358 tag component is visible.
11360 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

11393 with implementation.
11394 Documentation cleanup only.
11396 2007-08-31 Sergey Rybin <rybin@adacore.com>
11398 * vms_data.ads: Add new qualifier /STMT_NAME_ON_NEW_LINE for the new
11399 gnatpp '--separate-stmt-name' option.

11403 * gnat_ugn.texi: Add description for the new gnatpp
11404 '--separate-stmt-name' and '--use-on-new-line' options.
11406 2007-08-31 Ben Elliston <bje@au.ibm.com>

11419 * misc.c (gnat_type_max_size): Constify.
11421 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11423 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
11424 associated with Standard_Debug_Renaming_Type, to be used as the type of
11425 the special variables whose names provide debugger encodings for
11426 renaming declarations.
11428 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
11429 (Set_Debug_Renaming_Link): Change to set Node25.
11430 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
11431 (Write_Field25_Name): Add case for E_Variable to output
11432 "Debug_Renaming_Link".
11433 (Write_Field23_Name): Correct the output string for "Limited_View".
11435 * exp_dbug.adb: Add with and use of Tbuild.
11436 (Debug_Renaming_Declaration): Replace creation of an enumeration type
11437 and literal with creation of a variable of type
11438 Standard_Debug_Renaming_Type whose name encodes both the renamed object
11439 and the entity of the renaming declaration.
11440 (Qualify_Entity_Name): Add the delayed qualification of the entity name
11441 part of the name of a variable that has a Debug_Renaming_Link.
11443 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
11444 special type to be associated with variables that provide debugger
11445 encodings for renaming declarations.

11448 Ed Schonberg <schonberg@adacore.com>
11449 Javier Miranda <miranda@adacore.com>
11451 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
11452 ancestor part given by an aggregate to test for an unchecked conversion,
11453 since this can occur in some cases when the ancestor part is a function
11454 call, and we don't want to fall into the recursive call to this
11455 procedure in that case.
11457 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
11458 stream attributes on limited types to account for user-specified
11459 attributes as well as whether Input (resp. Output) becomes available
11460 due to Read (resp. Write) being available for the type. Change Boolean
11461 variable to the more accurate name
11462 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
11463 double-"not" predicate at beginning of return statement to more
11464 understandable form.
11466 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
11467 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
11468 in a block statement and use that as the first statement of the
11469 expanded return rather than incorrectly using the handled sequence as
11470 the first statement.
11472 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
11473 operation, generate an explicit freeze node for it rather than
11474 generating extra formals, to ensure that gigi has the proper order of
11475 elaboration for anonymous subtypes in the signature of the subprograms.
11476 (Build_In_Place_Formal): Move assertion to beginning of loop.
11477 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
11478 applied to a function call (occurs for some cases of 'Input).

11480 applied to a function call (occurs for some cases of 'Input).
11482 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
11483 2005, generate an extended return statement enclosing the result object
11486 * freeze.adb (Freeze_Record_Type): Extend the current management of
11487 components that are access type with an allocator as default value: add
11488 missing support to the use of qualified expressions of the
11489 allocator (which also cause freezing of the designated type!)
11490 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
11491 dispatching operation, since extra formals may be needed by calls to
11492 build-in-place functions (such as stream 'Input).
11494 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
11495 formals for 'Constrained and accessibility level in the case of a
11496 predefined dispatching operation.
11498 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
11499 point, no need to find the parent node.
11501 2007-08-16 Javier Miranda <miranda@adacore.com>
11503 * exp_attr.adb (Attribute_Priority): Add missing support for entries
11504 and entry barriers.
11506 2007-08-16 Javier Miranda <miranda@adacore.com>
11508 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
11509 is not really required and can introduce regression with the debugger.
11510 The original problem is fixed with the patch written for checks.adb.
11512 2007-08-16 Thomas Quinot <quinot@adacore.com>
11514 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
11515 Range_Check on Allocated_Table.
11517 2007-08-16 Vincent Celier <celier@adacore.com>
11519 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
11520 Including_Non_Switch set to False.
11521 (Gnatmake): For the compiler, call Test_If_Relative_Path with
11522 Including_Non_Switch set to False.
11524 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
11525 parameter Including_Non_Switch, defaulted to True. When
11526 Including_Non_Switch is False, options that are not switches and
11527 appear as relative path are not converted to absolute paths.
11529 2007-08-16 Nicolas Roche <roche@adacore.com>
11531 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
11534 * Make-lang.in: Update dependencies

11538 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
11539 currently inspected is a selected component, retrieve the entity of
11541 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
11542 from the immediate ancestor of Main_Unit_Entity.
11543 (Install_Limited_Withed_Unit): Do not install the limited view of
11544 package P if P is reachable through an ancestor chain from package C
11545 and C also has a with clause for P in its body.
11546 (Has_Limited_With_Clause): New routine.
11547 (Has_With_Clause): New routine.
11549 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11551 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
11552 generic for an enclosing instance is a global reference, even though
11553 its scope is the enclosing instance.
11555 2007-08-16 Gary Dismukes <dismukes@adacore.com>
11556 Javier Miranda <miranda@adacore.com>
11558 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
11559 initialize a limited object.
11560 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
11562 Make sure Has_Complex_Representation is inherited by derived type.
11564 2007-08-16 Robert Dewar <dewar@adacore.com>
11566 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
11569 2007-08-16 Ed Schonberg <schonberg@adacore.com>
11571 * sem_disp.adb (Check_Dispatching_Operation): If the operation
11572 implements an operation inherited from a progenitor interface, verify
11573 that they are subtype-conformant.

11576 Bob Duff <duff@adacore.com>
11577 Nicolas Setton <setton@adacore.com>
11579 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
11580 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
11581 the statement which is being resolved comes from a predefined library
11582 unit, all non-predefined library interpretations are skipped.
11583 (Resolve_Op_Concat): If string concatenation was folded in the parser,
11584 but the "&" is user defined, give an error, because the folding would
11587 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
11588 the parser has folded a long sequence of concatenations of string
11591 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
11592 and "JMP_BUF" variables as artificial.
11593 (N_String_Literal): Do not use alloca for very long string literals. Use
11594 xmalloc/free instead. Otherwise the stack might overflow.
11596 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
11599 2007-08-16 Vincent Celier <celier@adacore.com>
11601 * vms_conv.adb (Process_Argument): Ensure that project related options
11602 are not put in the -cargs section when using GNAT COMPILE.
11604 2007-08-16 Robert Dewar <dewar@adacore.com>
11606 * gnat_ugn.texi: Add note on preprocessing (output file not written)
11608 2007-08-16 Thomas Quinot <quinot@adacore.com>

11631 par-ch5.adb, par-ch10.adb, get_targ.adb, a-wtedit.adb, a-teioed.adb,
11632 s-osinte-solaris.adb, s-osinte-solaris.ads,
11633 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
11635 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
11636 switch -gnatyS. Enable -gnatyS in GNAT style check mode
11638 2007-08-14 Robert Dewar <dewar@adacore.com>
11639 Ed Schonberg <schonberg@adacore.com>
11641 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
11642 Suppress unmodified in-out parameter warning in some cases
11643 This patch is a also fairly significant change to the way suppressible
11644 checks are handled.
11646 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
11647 needed for access to concurrent record types generated by the expander.
11648 (Generate_Range_Check): When generating a temporary to capture the
11649 value of a conversion that requires a range check, set the type of the
11650 temporary before rewriting the node, so that the type is always
11651 properly placed for back-end use.
11652 (Apply_Float_Conversion_Check): Handle case where the conversion is
11654 (Get_Discriminal): Code reformatting. Climb the scope stack looking
11655 for a protected type in order to examine its discriminants.
11657 2007-08-14 Robert Dewar <dewar@adacore.com>

11659 Ed Schonberg <schonberg@adacore.com>
11660 Thomas Quinot <quinot@adacore.com>
11662 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
11663 a-stwisu.adb, a-strsup.adb: Fix warnings for range
11664 tests optimized out.
11666 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
11667 (Get_Allocator_Final_List): For the case of an anonymous access type
11668 that has a specified Associated_Final_Chain, do not go up to the
11670 (Expand_N_Type_Conversion): Test for the case of renamings of access
11671 parameters when deciding whether to apply a run-time accessibility
11673 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
11674 aggregate code before allocator, and ahead of declaration for
11675 temporary, to prevent access before elaboration when the allocator is
11676 an actual for an access parameter.
11677 (Expand_N_Type_Conversion): On an access type conversion involving an
11678 access parameter, do not apply an accessibility check when the
11679 operand's original node was an attribute other than 'Access. We now
11680 create access conversions for the expansion of 'Unchecked_Access and
11681 'Unrestricted_Access in certain cases and clearly accessibility should
11682 not be checked for those.
11684 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
11685 includes a type conversion of a packed component that has been expanded,
11686 recover the original expression for the object, and use this expression
11687 in the post-call assignment statement, so that the assignment is made
11688 to the object and not to a back-end temporary.
11689 (Freeze_Subprogram): In case of primitives of tagged types not defined
11690 at the library level force generation of code to register the primitive
11691 in the dispatch table. In addition some code reorganization has been
11692 done to leave the implementation clear.
11693 (Expand_Call): When expanding an inherited implicit conversion,
11694 preserve the type of the inherited function after the intrinsic
11695 operation has been expanded.
11697 * exp_ch2.ads, exp_ch2.adb
11698 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
11699 of an entry formal appearing in an assignment statement does not assign
11701 (Expand_Current_Value): Instead of calling a routine to determine
11702 whether the prefix of an attribute reference should be optimized or
11703 not, prevent the optimization of such prefixes all together.
11705 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
11706 component whose prefix is known to be of an access type is an implicit
11707 dereference and does not assign to the prefix.
11709 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11710 Robert Dewar <dewar@adacore.com>
11712 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
11713 itype is visited, make an entry into table to link associated node and
11715 Add comments and correct harmless error in Build_NCT_Hash_Tables
11716 (Array_Aggr_Subtype): Associate each itype created for an index type to
11717 the corresponding range construct, and not to the aggregate itself. to
11718 maintain a one-to-one correspondence between itype and its associated
11719 node, to prevent errors when complex expression is copied.
11720 Fix mishandling of multiple levels of parens
11722 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11723 treatment of limited views uniform for all visible declarations in a
11724 limited_withed package.
11725 (New_Copy_Tree): If hash table is being used and itype is visited,
11726 make an entry into table to link associated node and new itype.
11727 (Resolve_Record_Aggregate): Do not add an others box association for a
11728 discriminated record component that has only discriminants, when there
11729 is a box association for the component itself.
11731 * par-ch4.adb: Fix mishandling of multiple levels of parens
11733 2007-08-14 Robert Dewar <dewar@adacore.com>
11735 * comperr.adb: Fix problem with suppressing warning messages from gigi
11737 * erroutc.ads, erroutc.adb, errout.ads,
11738 errout.adb (Write_Eol): Remove trailing spaces before writing the line
11739 (Write_Eol_Keep_Blanks): New procedure to write a line, including
11740 possible trailing spaces.
11741 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
11742 Fix problem with suppressing warning messages from back end
11743 Improve handling of deleted warnings
11746 Fix problem with suppressing warning messages from back end
11747 Handle setting of Static_Dispatch_Tables flag.
11750 Fix problem with suppressing warning messages from back end
11752 * exp_intr.adb: Improve handling of deleted warnings

11769 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
11770 to make treatment of limited views uniform for all visible declarations
11771 in a limited_withed package.
11772 Improve warnings for in out parameters
11773 (Set_Related_Interaface/Related_Interface): Allow the use of this
11774 attribute with constants.
11775 (Write_Field26_Name): Handle attribute Related_Interface in constants.
11776 Warn on duplicate pragma Preelaborable_Initialialization
11778 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11779 generation of a freezing node to ensure proper management of null
11780 excluding access types in the backend.
11781 (Create_Extra_Formals): Test base type of the formal when checking for
11782 the need to add an extra accessibility-level formal. Pass the entity E
11783 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11784 originally being done in a couple of cases), to ensure that the
11785 Extra_Formals list gets set on the entity E when the first entity is
11787 (Conforming_Types): Add missing calls to Base_Type to the code that
11788 handles anonymous access types. This is required to handle the
11789 general case because Process_Formals builds internal subtype entities
11790 to handle null-excluding access types.
11791 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11792 functions that need it, even when not marked Requires_Overriding.
11793 Improve warnings for in out parameters
11794 (Analyze_Function_Return): Warn for disallowed null return
11795 Warn on return from procedure with unset out parameter
11796 Ensure consistent use of # in error messages
11797 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11798 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11799 the implicit conversion of the expression done for anonymous access
11800 types. This is required to generate the code of the null excluding
11801 check (if required).
11803 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11804 A formal parameter is never publicly referenceable outside of its body.
11805 (Check_References): For an unreferenced formal parameter in an accept
11806 statement, use the same warning circuitry as for subprogram formal
11808 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11809 Output_Unreferenced_Messages, containing the part of that routine that
11810 is now reused for entry formals as described above.
11811 (Goto_Spec_Entity): New function
11812 (Check_References): Do not give IN OUT warning for dispatching operation
11813 Improve warnings for in out parameters
11814 (Test_Ref): Check that the entity is not undefinite before calling
11815 Scope_Within, in order to avoid infinite loops.
11816 Warn on return from procedure with unset out parameter
11817 Improved warnings for unused variables

11823 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11824 (Expand_N_Attribute_Reference): Further unify the handling of the
11825 three forms of access attributes, using common code now for all three
11826 cases. Add a test for the case of applying an access attribute to
11827 an explicit dereference when the context is an access-to-interface
11828 type. In that case we need to apply the conversion to the prefix
11829 of the explicit dereference rather than the prefix of the attribute.
11830 (Attribute_Version, UET_Address): Set entity as internal to ensure
11831 proper dg output of implicit importation.
11832 (Expand_Access_To_Type): Removed.
11833 (Expand_N_Attribute_Reference): Merge the code from the three cases
11834 of access attributes, since the processing is largely identical for
11835 these cases. The substantive fix here is to process the case of a
11836 type name prefix (current instance case) before handling the case
11837 of interface prefixes.

11844 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11845 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11846 type that is an anonymous access to controlled object, establish
11847 an associated finalization chain to avoid corrupting the global
11848 finalization list when a dynamically allocated object designated
11849 by such a component is deallocated.
11850 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11851 functions that need it, even when not marked Requires_Overriding.
11852 (Initialize_Tag): Replace call to has_discriminants by call to
11853 Is_Variable_Size_Record in the circuitry that handles the
11854 initialization of secondary tags.
11855 (Is_Variable_Size_Record): New implementation.
11856 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11857 Suppress_Initialization pragma for a derived type.
11858 (Is_Variable_Size_Record): New subprogram.
11859 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11860 initial version of this routine and also fixes problems causing
11861 incomplete initialization of the table of interfaces.

11920 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11921 first formal of the thunk is always associated with the controlling
11922 type. In addition perform the following code cleanup: remove formal
11923 Thunk_Alias which is no longer required, cleanup evaluation of the
11924 the controlling type, and update the documentation.

11949 * exp_util.ads, exp_util.adb:
11950 This patch replaces a number of occurrences of explicit tests for N_Null
11951 with calls to Known_Null. This improves tracking of null values, since
11952 Known_Null also catches null constants, and variables currently known to
11953 be null, so we get better tracking.
11954 (Ensure_Defined): create an itype reference only in the scope of the
11956 (Side_Effect_Free): A selected component of an access type that
11957 denotes a component with a rep clause must be treated as not

11959 value may be affected by a renaming.
11960 (Expand_Subtype_From_Expr): For limited objects initialized with build
11961 in place function calls, do nothing; otherwise we prematurely introduce
11962 an N_Reference node in the expression initializing the object, which
11963 breaks the circuitry that detects and adds the additional arguments to
11964 the called function. Bug found working in the new patch for statically
11965 allocated dispatch tables.
11966 (Is_Library_Level_Tagged_Type): New subprogram.
11967 (Remove_Side_Effects): If the expression of an elementary type is an
11968 operator treat as a function call.
11969 (Make_Literal_Range): If the index type of the array is not integer, use
11970 attributes properly to compute the constraint on the resulting aggregate
11973 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11974 class-wide type whose base type is an incomplete private type, leave
11975 class-wide type unfrozen so that freeze nodes can be generated
11976 properly at a later point.
11977 (Freeze_Entity, array case): Handle case of pragma Pack and component
11978 size attributre clause for same array.

12606 (Set_Item): When the new item is an element of the currently allocated
12607 table passed by reference, save a copy on the stack if we're going

12624 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
12625 derived type with interface progenitors use the analyzed formal as the
12626 parent of the actual, to create renamings for all the inherited
12627 operations in Derive_Subprograms.
12628 (Collect_Previous_Instances): new procedure within of
12629 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
12630 unit being loaded, to ensure that the generation of global symbols is
12631 consistent in different compilation modes.
12632 (Is_Tagged_Ancestor): New function testing the ancestor relation that
12633 takes progenitor types into account.
12634 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
12635 traversing over the primitives of the formal and actual types to locate
12636 any abstract subprograms of the actual type that correspond to a
12637 nonabstract subprogram of the formal type's ancestor type(s), and issue
12638 an error if such is found.
12639 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
12640 Instantiate_Package_Body, Instantiate_Subprogram_Body):
12641 Remove bogus guard around calls to Inherit_Context.
12642 (Reset_Entity): If the entity is the selector of a selected component
12643 that denotes a named number, propagate constant-folding to the generic

12651 parameter to determine whether operation applies to the prefix.
12652 (Complete_Object_Operation): If actual has an access type and
12653 controlling formal is not an in_parameter, reject the actual if it is
12654 an access_to_constant type.
12655 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
12656 type, the candidate operations are found in the scope of declaration of
12657 the type, because the type has no primitive subprograms.
12658 (Analyze_Selected_Component): If prefix is class-wide, and root type is
12659 a private extension, only examine visible components before trying to
12660 analyze as a prefixed call.
12661 Change Entity_List to Type_To_Use, for better readability.
12662 (Has_Fixed_Op): Use base type when checking whether the type of an

12671 formal At_Any_Place indicating, when True, that we want to test for
12672 availability of the stream attribute at any place (as opposed to the
12673 current visibility context only).
12674 (Missing_Read_Write_Attributes): A stream attribute is missing for the
12675 purpose of enforcing E.2.2(8) only if it is not available at any place.
12676 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
12677 when checking the legality of an extension aggregate in a preelaborable
12678 package. Treat the literal null as a valid default expression in a
12679 component declaration for a type with preelaborable initialization.
12680 A limited interface is a legal progenitor for the designated type of a
12681 remote access to class-wide type.

12693 mark the full view as referenced, to prevent spurious warnings.
12694 (Find_Selected_Component, Has_Components): Handle properly non-limited
12695 views that are themselves incomplete types.
12696 Handle interfaces visible through limited-with clauses.
12697 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
12698 subprogram generic actual for which we have generated a renaming.
12699 Warn when the renaming introduces a homonym of
12700 the renamed entity, and the renamed entity is directly visible.

12706 appear in the subtree to the current allocator if it is not a static
12708 (Resolve_Allocator): Perform cleanup if resolution has determined that
12709 the allocator is not a coextension.
12710 (Resolve): Skip an interpretation hidden by an abstract operator only
12711 when the type of the interpretation matches that of the context.
12712 (Resolve): When looping through all possible interpretations of a node,
12713 do not consider those that are hidden by abstract operators.
12714 (Resolve_Actuals): When verifying that an access to class-wide object
12715 is an actual for a controlling formal, ignore anonymous access to
12716 subprograms whose return type is an access to class_wide type.
12717 (Resolve_Slice): If the prefix of the slice is a selected component
12718 whose type depends on discriminants, build its actual subtype before
12719 applying range checks on the bounds of the slice.
12720 (Valid_Conversion): In an instance or inlined body, compare root types,
12721 to prevent anomalies between private and public views.
12722 (Resolve): Improve error message for ambiguous fixed multiplication
12723 expressions that involve universal_fixed multiplying operations.

12743 elabration statements, register the package with the name server
12744 at the beginning, not at the end, of the elaboration statements so
12745 that they can create remote access to subprogram values that designate
12746 remote subprograms from the package.

13894 Arnaud Charlet <charlet@adacore.com>
13896 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13897 applicable to types that have the With_Type flag set. Returns the
13898 non-limited view of the type, if available, otherwise the type itself.
13899 For class-wide types, there is no direct link in the tree, so we have
13900 to retrieve the class-wide type of the non-limited view of the Etype.
13901 New attributes Static_Initialization and Static_Elaboration_Desired.
13902 Remove the pragma Thread_Body, and the associated flag
13903 Is_Thread_Body in entities, and all related code.

13916 (Original_Access_Type): Remove, not needed.
13917 (Root_Type): Handle properly subtypes of class-wide-types.
13920 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13921 class-wide types visible through limited-with clauses.
13922 (Try_Primitive_Operation): When examining all primitive operations of a
13923 tagged type, do not consider subprograms labeled as hidden unless they
13924 belong to a private generic type with a tagged parent.
13925 (Try_Object_Operation): Extensive rewriting, to handle properly various
13926 overloading cases, when several ancestors may have class-wide operations
13927 that are possible candidates, and when the overloaded functions return
13928 array types and have defaulted parameters so that the call may be
13929 interpreted as an indexing.
13930 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13931 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13932 successive actuals before analyzing the call itself.
13933 (Try_Primitive_Operation): A primitive operation is compatible with the
13934 prefix if the prefix has a synchronized type and the type of the formal
13935 is its corresponding record, as can be the case when the primitive
13936 operation is declared outside of the body of the type.
13937 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13938 perform homonym traversal, looking for class-wide operation matches
13939 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13940 access parameters are now restricted to anonymous access types.
13941 (Mark_Allocator): An allocator with a discriminant association parent is
13943 (Try_One_Prefix_Interpretation): If the type of the object is
13944 incomplete, as can be happen when it is a limited view obtained through
13945 a limited_with_clause, the selected component is not part of a prefixed
13947 (Complete_Object_Operation): Diagnose properly an object that is not
13948 aliased when the corresponding controlling formal is an access
13950 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13951 ambiguous calls in prefixed notation, where two primitives differ only
13952 in that the controlling argument of one is an access parameter.
13954 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13955 whether a function that returns an unconstrained type can be inlined.
13956 (Process_Formals): Diagnose properly the illegal use of an incomplete
13957 type in the profile of an access_to_subprogram declaration.
13958 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13959 operations are attached to the corresponding record.
13960 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13961 When processing a primitive of a concurrent type which implements an
13962 interface change the type of all controlling formals to that of the
13963 corresponding record type.
13964 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13965 to determine the tagged type to which a primitive belongs.
13966 (Check_Conventions): Capture condition to ignore a primitive operation
13967 (which is shared between the loop in Check_Conventions and the one in
13968 Check_Convention) in a new local function Skip_Check.
13969 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13970 confusion with Check_Conventions' own Prim_Op local variable.
13971 (Create_Extra_Formals): Test for a tagged result type rather than a
13972 controlling result when determining whether to add a BIP_Alloc_Form
13973 formal and a BIP_Final_List formal to the function.
13974 (Check_Conformance); For parameters that are anonymous access types,
13975 subtype conformance requires that the not null and the constant
13976 indicators must match
13977 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13978 to retrieve the appropriate type when processing a concurrent type
13979 declared within a generic. Minor comment reformatting. Change invocation
13980 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13982 (Analyze_Subprogram_Body): If the return type of a function is an
13983 anonymous access to the limited view of a class-wide type, and the
13984 non-limited view of the type is available, update the type of the
13985 function so that code can be generated.
13986 (Process_Formals): In case of access-subtype itype whose designated
13987 type is also an itype (situation that happens now with access to
13988 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13989 attribute to avoid backend problems.
13990 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13991 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13992 anonymous types' designated types are same before testing
13993 Subtypes_Statically_Match.
13994 (Create_Extra_Formals): Test for a named access parameter that is a
13995 controlling formal as an additional condition for adding an
13996 accessibility level formal. This can occur in the subp type created for
13997 dispatching calls in Expand_Dispatching_Call, and allows calling
13998 Create_Extra_Formals from that procedure rather than special-casing the
13999 extra formals there.
14000 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
14001 when the function has a controlling result.
14002 (Check_Returns): Add much more knowledge of the optimization of local
14003 raise statements to gotos, to retain proper warnings in this case.
14004 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
14005 nodes when looking for last statement.
14007 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
14008 class-wide types visible through limited with clauses.
14009 (Add_One_Interp): If the operands are anonymous access types, the
14010 predefined operator on universal_access is immediately visibles
14011 (Find_Unique_Type): Handle anonymous access to subprogram types just as
14012 other anonymous access types.
14013 (Disambiguate): Take into account CIL convention.
14014 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

14035 in extension aggregates.
14036 (Flatten): Other conditions being met, an aggregate is static if the
14037 low bound given by component associations is different from the low
14038 bound of the base index type.
14039 (Packed_Array_Aggregate_Handled): If the component type is itself a
14040 packed array or record, the front-end must expand into assignments.
14041 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
14042 Init_Pr, instead of Ancestor_Is_Expression.
14043 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
14044 coextension chain root, either generate a list controller or use the
14045 already existing one.
14046 (Static_Array_Aggregate): New procedure to construct a positional
14047 aggregate that can be handled by the backend, when all bounds and
14048 components are compile-time known constants.
14049 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
14050 types covering interface types into assignments.
14051 (Replace_Type): move to Build_Record_Aggr_Code.
14052 (Expand_Record_Aggr_Code): if the target of the aggregate is an
14053 interface type, convert to the definite type of the aggregate itself,
14054 so that needed components are visible.
14055 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
14056 components and the context is an extended return statement do not
14057 create a transient block for it, to prevent premature finalization
14058 before the return is executed.
14059 (Gen_Assign): Do not generate a call to deep adjust routine if the
14060 component type is itself an array of controlled (sub)-components
14061 initialized with an inner aggregate.
14062 (Component_Check): New name for Static_Check. This name is now more
14063 appropriate, and documentation is added which was missing.
14064 (Component_Check): Add test for bit aligned component value
14065 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
14066 Tagged_Comps, name is more appropriate given added function below.
14067 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

14073 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
14074 Terminated: Add unchecked type conversion from System.Address to
14075 System.Tasking.Task_Id when calling the predefined primitive
14077 Disable new Ada 05 accessibility check for JVM.NET targets, which
14078 cannot be implemented in a practical way.
14079 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
14080 the sources always references the tag of the actual object. Therefore,
14081 if 'Tag is applied in the sources to class-wide interface objects we
14082 generate code that displaces "this" to reference the base of the object.
14083 (Expand_N_Attribute_Reference, case Size): Return specified size if
14084 known to front end.
14085 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
14086 has code that displaces the pointer of the object to manage interface
14087 types. However this code must not be executed when the prefix is a
14088 subprogram. This bug caused the wrong expansion of the internally
14089 generated assignment that fills the dispatch table when the primitive
14090 is a function returning a class-wide interface type.
14091 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
14092 Set_Attribute_Name for Name_Unaligned_Valid.

14095 Gary Dismukes <dismukes@adacore.com>
14097 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
14098 If the initialization is the equivalent aggregate of the initialization
14099 procedure of the type, do not remove it.
14100 (Expand_N_Attribute_Definition_Clause): Exclude access variables
14101 initialized to null from having their expression reset to empty and
14102 note this exception in the comment.

14109 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
14110 Add "with" and "use" clauses for Sem_Attr.
14111 (Expand_Current_Value): Do not replace occurences of attribute
14112 references where the prefix must be a simple name.
14114 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
14115 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
14116 Attribute_Requires_Simple_Name_Prefix.
14117 (Name_Modifies_Prefix): Body of new function.
14118 (Requires_Simple_Name_Prefix): Body of new function.
14119 (Resolve_Attribute, case Access): Improve error message for case of
14120 mismatched conventions.
14121 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
14123 (Analyze_Attribute, case 'Access): If the type of the prefix is a
14124 constrained subtype for a nominal unconstrained type, use its base type
14125 to check for conformance with the context.
14126 (Resolve_Attribute): Remove test of the access type being associated
14127 with a return statement from condition for performing accessibility
14128 checks on access attributes, since this case is now captured by
14129 Is_Local_Anonymous_Access.
14130 (Analyze_Access_Attribute): Set Address_Taken on entity
14131 (Analyze_Attribute, case Address): Set Address_Taken on entity
14132 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
14133 validating an access attribute whose prefix is a current instance.
14134 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
14135 applied to dispatching operations, if freezing is required then we set
14136 the attribute Has_Delayed_Freeze in the prefix's entity.
14137 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
14138 current scope if access of local subprogram taken
14139 (Analyze_Access_Attribute): Check legality of self-reference even if the
14140 expression comes from source, as when a single component association in
14141 an aggregate has a box association.
14142 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
14143 the prefix if it is a protected operation and the attribute is
14144 Unrestricted_Access.
14145 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
14146 reference to the base type of the context, to force a constraint check
14147 when the context is an access subtype with an explicit constraint.
14148 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
14149 node is rewritten as an interface conversion. leave unanalyzed after
14150 resolution, to ensure that type checking against the context will take

14154 Javier Miranda <miranda@adacore.com>
14155 Robert Dewar <dewar@adacore.com>
14157 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
14158 wrapper when the full view of the controlling type of an inherited
14159 function that dispatches on result implements interfaces.
14160 (Expand_N_Object_Declaration): In cases where the type of the
14161 declaration is anonymous access, create finalization list for it.
14162 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
14163 if the object has no explicit initialization, to match description of
14164 functionality of pragam Persistent_BSS.
14165 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
14166 new function to build static aggregates, to replace initialization call
14167 when static initialization is desired.
14168 (Freeze_Type): Generate a list controller for an access type whenever
14169 its designated type has controlled anonymous access discriminants.
14170 (Build_Equivalent_Aggregate): New procedure to compute a static
14171 aggregate to be used as default initialization for composite types,
14172 instead of a generating a call to the initialization procedure for the
14174 (Build_Initialization_Call): When available, replace a call to the
14175 initialization procedure with a copy of the equivalent static aggregate
14177 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
14178 declarations for objects of a class-wide interface type, rather than
14179 just identifiers, to prevent visibility problems.
14180 (Expand_N_Object_Declaration): When expanding the declaration for an
14181 object of a class-wide interface type, preserve the homonym chain of
14182 the original entity before exchanging it with that of the generated
14183 renaming declaration.
14184 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
14185 active, because there is no way to handle the exception.
14186 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
14187 to do a minimum decoration of the Access_Disp_Table list.
14188 (Expand_Record_Controller): Avoid the addition of the controller between
14189 the component containing the tag of a secondary dispatch table and its
14190 adjacent component that stores the offset to the base of the object.
14191 This latter component is only generated when the parent type has
14192 discriminants ---documented in Add_Interface_Tag_Components).
14193 (Apply_Array_Size_Check): Removed, no longer needed.
14194 (Expand_N_Full_Type_Declaration): If the type has anonymous access
14195 components, create a Master_Entity for it only if it contains tasks.
14196 (Build_Init_Procedure): Suppress the tag assignment compiling under
14198 (Freeze_Record_Type): Remove code associated with creation of dispatch
14200 (Init_Secondary_Tags): Update type of actuals when generating calls to
14201 Ada.Tags.Set_Offset_To_Top
14202 (Stream_Operation_OK): Disable use of streams compiling under no
14204 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
14205 if Has_Init_Expression set.
14206 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
14207 Register_Primitive, which provides the same functionality.
14208 (Requires_Init_Proc): Return false in case of interface types.
14209 (Add_Secondary_Tables): Use the new attribute Related_Interface to
14211 (Predefined_Primitive_Freeze): Do not assume that an internal entity
14212 is always associated with a predefined primitive because the internal
14213 entities associated with interface types are not predefined primitives.
14214 Therefore, the call to Is_Internal is replaced by a call to the
14215 function Is_Predefined_Dispatching_Operation.
14216 (Make_Eq_If): When generating the list of comparisons for the
14217 components of a given variant, omit the controller component that is
14218 present if the variant has controlled components.

14221 Hristian Kirtchev <kirtchev@adacore.com>
14222 Bob Duff <duff@adacore.com>
14224 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
14225 handle the creation of finalization lists and calls for nested
14226 coextensions when the root of the chains is part of a return statement.
14227 (Inside_A_Return_Statement): New function inside Complete_Coextension_
14229 (Expand_Record_Equality): Skip components that are interface types.
14230 (Displace_Allocator_Pointer): Add missing support for interface subtypes
14231 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
14232 with Rewrite_Coextension. Change the condition for detecting coextension
14234 (Is_Local_Access_Discriminant): Removed.
14235 (Rewrite_Coextension): New routine which rewrites a static coextension
14236 as a temporary and uses its unrestricted access in the construction of
14238 (Complete_Coextension_Finalization): New routine. Generate finalization
14239 attachment calls to all delayed coextensions.
14240 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
14241 the allocator is not a coextension itself and has delayed coextensions.
14242 If the current allocator is controlled, but also a coextension, delay
14243 the generation of the finalization attachment call.
14244 Rename local variable "Node" to "Nod" in order to avoid confusion with
14246 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
14247 limited types that are not inherently limited. Such an allocator is
14248 illegal, but is generated by the expander for a return statement, to
14249 copy the result onto the secondary stack. This is the only case where a
14250 limited object can be copied. Generate code to displace the pointer
14251 to the object if the qualified expression is a class-wide interface
14252 object. Such displacement was missing and hence the copy of the object
14254 (Apply_Accessibility_Check): Handle allocated objects initialized in
14256 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
14257 and Expand_Allocator_Expression. Allocating class-wide interface objects
14258 this routine displaces the pointer to the allocated object to reference
14259 the component referencing the corresponding secondary dispatch table.
14260 Expand_Allocator_Expression): Add missing support to allocate class-wide
14261 interface objects initialized with a qualified expression.
14262 (Get_Allocator_Final_List): Test for an anonymous access type that is a
14263 function result type, and use the finalization list associated with the
14264 function scope in that case (such an anonymous type should not be
14265 treated like an access parameter's type).

14268 Gary Dismukes <dismukes@adacore.com>
14269 Javier Miranda <miranda@adacore.com>
14271 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
14272 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
14273 required exception handler.
14274 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
14275 properly the case of a function whose return type is a limited
14276 class-wide interface type. Modify the code of the accessibility
14277 check to handle class-wide interface objects. In this case we need to
14278 displace "this" to reference the primary dispatch table to get access
14279 to the TSD of the object (to evaluate its accessibility level).
14280 (Expand_N_Extended_Return_Statement): Test for a tagged result type
14281 rather than a controlling result as one of the conditions for
14282 generating tests of the implicit BIP_Alloc_Form formal. The
14283 initialization assignment is also handled according to whether the
14284 result is tagged instead of controlling.
14285 In the case where the init assignment is inserted in the "then" part of
14286 the allocation conditional, rewrite the target to be a dereference of
14287 the implicit BIP_Object_Access formal.
14288 If the returned value is unconstrained and created on the secondary
14289 stack, mark the enclosing block and function so that the secondary
14290 stack is not reclaimed on return.
14291 Treat returns from functions with controlling results similarly to
14292 returns from functions with unconstrained result subtypes.
14293 If the object returned is unconstrained, and an allocator must be
14294 created for it, analyze the allocator once the block for the extended
14295 return is installed, to ensure that finalizable components
14296 of the expression use the proper finalization list. Guard the call to
14297 Move_Final_List with a check that there is something to finalize.
14298 (Make_Tag_Ctrl_Assignment): Use "old" handling
14299 of controlled type assignment for virtual machines, since new code uses
14300 unsupported features (such as direct access to bytes in memory).
14302 2007-06-06 Gary Dismukes <dismukes@adacore.com>
14303 Ed Schonberg <schonberg@adacore.com>
14305 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
14306 accessibility actual, check for the case of an aliased object that has
14307 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
14308 we fall into processing for the attribute rather than the name of the
14310 (Expand_Inline_Call): If an actual is a literal, and the corresponding
14311 formal has its address taken in the body, create a temporary to capture
14312 value. If the return type is a limited interface, do not treat the
14313 return value as Controlled.
14314 (Is_In_Place_Function): If the return type is a limited interface,
14315 treat as returning in place. The actual returned object may not always
14316 be limited, but the caller has to assume that it is returned in place.
14317 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
14318 context of an allocator, use the correct finalization chain (that is,
14319 the chain belonging to the access type, rather than the chain belonging
14320 to the current scope).
14321 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
14322 result type rather than a controlling result as a precondition for
14323 adding an allocation form actual to a build-in-place call.
14324 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
14325 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
14326 primitive in the dispatch tables. This work is now done by Make_DT when
14327 the type is frozen.
14328 (Register_Predefined_DT_Entry): Removed.
14329 (Add_Return): If end label is not present, use sloc of last statement
14330 for generated return statement in procedure, for better gdb behavior
14332 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
14333 object address nodes to ensure proper processing by routines like
14335 (Expand_Call): Fix generation of validity check for parameter
14336 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
14337 the allocation form parameter if the result subtype is constrained,
14338 except when the function has a controlling result.
14339 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
14340 rather than Is_Controlled and Has_Controlled_Component, since we want to
14341 include class-wide result types in this treatment. Also test for a
14342 controlling result, since that also requires passing a finalization
14344 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
14345 even when the result subtype is constrained, to handle calls involving
14346 controlling results.
14347 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
14348 is now called even when the result subtype is constrained, to handle
14349 calls involving controlling results.
14350 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
14351 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
14352 now performs the test).
14353 (Make_Build_In_Place_Call_In_Object_Declaration):
14354 Add_Alloc_Form_Actual_* is now called even when the result subtype is
14355 constrained, to handle calls involving controlling results.
14356 (Add_Return): Accomodate rewritten pattern from local raise to goto
14357 transformation, so that we still recognize an transfer statement
14358 and do the right thing here in that case.
14359 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
14360 and end of subprogram code.
14361 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
14362 support for primitives that are functions (without formals) with a
14363 controlling result.
14364 (Inherited_From_Formal): If the actual subtype has not generic parent
14365 type, it is not an actual for a formal derived type, and there is no
14366 operation to inherit from the formal.
14368 2007-06-06 Ed Schonberg <schonberg@adacore.com>
14369 Thomas Quinot <quinot@adacore.com>
14371 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
14372 inserted cleanup code appropriately for GDB use.
14373 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
14374 exception handler for Deep_Adjust or Deep_Finalize.
14375 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
14376 Raise_From_Controlled_Operation is available, use a call to that
14377 subprogram instead of a plain "raise Program_Error" node to raise
14378 Program_Error if an exception is propagated from an Adjust or Finalize
14380 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
14381 appears in the optional statement list of a triggering alternative, the
14382 scope actions can be inserted directly there, and not in the list that
14383 includes the asynchronous select itself.
14385 2007-06-06 Ed Schonberg <schonberg@adacore.com>

14387 Hristian Kirtchev <kirtchev@adacore.com>
14389 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
14390 generated exception handler appropriately when debugging generated code.
14391 Deal properly with No_Exception_Propagation restriction mode.
14392 (Expand_N_Abort_Statement): Add an unchecked type conversion from
14393 System.Address to System.Tasking.Task_Id when processing the result of
14394 the predefined primitive _disp_get_task_id.
14395 (Expand_N_Asynchronous_Select): Clarify comment.
14396 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
14397 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
14398 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
14399 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
14400 privals and for generated call to Complete_Entry_Body, for better gdb
14402 (Copy_Result_Type): Utility to construct a parameter and result profile
14403 for protected functions whose return type is an anonymous access to
14405 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
14407 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
14408 point when the local-raise-to-goto transformation has taken place.
14410 2007-06-06 Javier Miranda <miranda@adacore.com>
14411 Nicolas Setton <setton@adacore.com>
14413 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
14414 functionality when the backend is generating code.
14415 Otherwise any serious error
14416 reported by the backend calling the frontend routine Error_Msg
14417 changes the Compilation_Mode to Check_Semantics, disables the
14418 functionality of this routine and causes the generation of
14419 spureous additional errors.
14421 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
14422 debugging information now generated by the compiler for fat-pointer
14424 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
14426 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
14428 2007-06-06 Thomas Quinot <quinot@adacore.com>
14430 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
14431 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14432 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
14433 For a remote call to a function with a classwide return type, apply an
14434 E.4(18) check to the returned value.
14435 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
14436 stream attributes of the designated type of an RACW, as they are not
14437 dispatching primitive operations.
14439 2007-06-06 Geert Bosch <bosch@adacore.com>
14441 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
14443 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
14445 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
14446 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
14448 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
14450 2007-06-06 Javier Miranda <miranda@adacore.com>
14452 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
14453 attribute compiling package Ada.Tags under No_Run_Time_Mode.
14455 2007-06-06 Javier Miranda <miranda@adacore.com>
14457 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
14458 deallocation of class-wide interface objects.
14459 (Expand_Dispatching_Constructor_Call): Take into account that if the
14460 result of the dispatching constructor is an interface type, the
14461 function returns a class-wide interface type; otherwise the returned
14462 object would be actual. The frontend previously accepted returning
14463 interface types because Expand_Interface_Actuals silently performed
14464 the management of the returned type "as if" it were a class-wide
14466 (Expand_Dispatching_Constructor_Call): Replace call to
14467 Make_DT_Access_Action by direct call to Make_Function_Call.
14469 2007-06-06 Robert Dewar <dewar@adacore.com>
14470 Ed Schonberg <schonberg@adacore.com>
14472 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
14473 compute masking constant, since we now set Esize properly to the
14475 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
14476 to match the alignment.
14477 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
14478 packed arrays of 8 bits or less.
14480 * freeze.adb (Freeze_Entity): When freezing the formals of a
14481 subprogram, freeze the designated type of a parameter of an access type
14482 only if it is an access parameter.
14483 Increase size of C convention enumeration object
14484 (Freeze_Entity, array type case): Make sure Esize value is properly
14485 adjusted for the alignment if it is known.
14486 (Freeze_Entity, array type case): When checking bit packed arrays for
14487 the size being incorrect, check RM_Size, not Esize.
14488 (Freeze_Record_Type): Check for bad discriminated record convention

15065 discriminants of nonlimited types.
15066 (Analyze_Interface_Type_Declaration): Complete the decoration of the
15067 class-wide entity it is is already present. This situation occurs if

15086 (Array_Aggr_Subtype): Indicate to the backend that the size of arrays
15087 associated with dispatch tables is known at compile time.
15088 (Get_Value): If an association in a record aggregate has a box
15089 association, and the corresponding record component has a default
15090 expression, always copy the default expression, even when the
15091 association has a single choice, in order to create a proper
15092 association for the expanded aggregate.

15316 both entities. This is required to statically build the dispatch table.
15317 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
15318 of calling Set_All_DT_Position to re-evaluate the position of the
15319 entries in the dispatch table. Such reevaluation is not desired if

15390 (Rmsg_28): Fix description for E.4(18) check.
15391 (Raise_Current_Excep): Call Debug_Raise_Exception just before
15392 propagation starts, to let debuggers know about the event in a reliable
15394 Take the address of E and dereference to make sure it is homed on stack

16438 attempt to derive from a synchronized tagged type.
16439 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

16446 Check_Anonymous_Access_Components rather than Empty.
16447 (Make_Incomplete_Type_Declaration): Add test for case where the type has

16529 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
16530 when -gnatg is not specified.

16560 (Convert_Aggr_In_Allocator): If the allocator is for an access
16561 discriminant and the type is controlled. do not place on a finalization
16562 list at this point. The proper list will be determined from the

16582 parameter of the containing subprogram.
16583 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
16584 under No_Dispatching_Calls restriction. During the semantic analysis
16585 we already notified such violation.

16607 value that is used in the membership test but also to fix the size
16608 of the table of ancestors.
16609 (Expand_Interface_Conversion): Insert function body at the closest place

16730 from the the declaration. Prevents errors on null-excluding access
16733 2007-04-06 Thomas Quinot <quinot@adacore.com>
16734 Pablo Oliveira <oliveira@adacore.com>
16736 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
16737 Do an Unchecked_Conversion to handle the passage from the Underlying
16738 Type to the Base Type when calling Build_To_Any_Call and
16739 Build_From_Any_Call.
16740 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16741 E_Constant, depending upon Variable formal.
16742 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16743 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
16744 parameter that requires an extra constrained parameter, declare
16745 temporary for actual as a variable, not a constant.
16746 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16747 the unit being compiled is the one that contains the stub type.
16748 Change primitive operation name for the RACW associated with a RAS
16749 from Call to _Call so it cannot clash with any legal identifier.
16750 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16752 (Append_RACW_Bodies): New subprogram.
16753 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16754 Add_Receiving_Stubs_To_Declarations functions.
16755 When expanding a package body, this list correspond to the
16756 statements in the HSS at the end of the pacakge.
16757 When expanding a package spec, this list correspond to the
16759 (Add_Receiving_Stubs_To_Declarations): Append the function
16760 registering the receiving stubs at the end of the 'Stmts' list.
16761 (RCI_Package_Locator): Pass the new Version generic formal when
16762 instantiating a RCI_Locator package.
16763 (Build_From_Any_Function): To compute the High bound for an
16764 unconstrained array actual, we add the Low bound with the length.
16765 Thus we must convert the low bound and the length to an appropriate
16766 type before doing the sum.
16767 (Build_Subprogram_Receiving_Stubs, PolyORB):
16768 * Retrieve the extra formals parameters at the
16769 end of the parameter stream.
16770 * Use Move_Any_Value to write back out parameters
16771 after executing the request as it is more efficient
16772 than Copy_Any_Value.
16773 * Build the any containing Extra Formals with the
16774 appropriate typecode.
16775 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16776 empty Component_List.
16777 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
16778 the tree the declaration for an object that serves as actual parameter
16779 in server-side stubs.
16780 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
16781 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
16782 Use Build_Actual_Object_Declaration to prepare the actuals.
16783 (Add_Parameter_To_NVList): Set the parameter mode to In for
16784 Extra Constrained Parameters.
16785 (Build_General_Calling_Stubs): Set the parameter type to boolean for
16786 Extra Constrained parameters.
16787 (Build_To_Any_Function, Build_From_Any_Function,
16788 Built_TypeCode_Function): When Typ is implicit, call the correct
16789 function with the first not implicit parent type.
16790 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16791 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16792 typecode from the Etype. Therefore we retrieve the correct typecode
16793 with a call to Get_Any_Type.
16794 (Copy_Specification): Do controlling formal type substitution based on
16795 Is_Controlling_Formal flag, instead of caller-provided object type.
16796 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16797 a RACW primitive operation, we might get a subprogram declaration for an
16798 ancestor of the RACW designated type (not for the designated type
16799 itself), in the case where this operation is inherited. In this case we
16800 have no easy means of determining the original tagged type for which
16801 the primitive was declared, so instead we now rely on
16802 Copy_Specification to use the Is_Controlling_Formal flag to determine
16803 which formals require type substitution.

16809 GNAT.Current_Exception are not allowed if pragma Restrictions
16810 (No_Exception_Propagation) is set and in any case make the associated
16811 handler unsuitable as a target for a local raise statement.
16812 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16813 run-time subprogram CW_Membership by call to Build_CW_Membership.
16814 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16815 by a function call, a temporary must be created before expanding the
16816 Constructor_Call itself, to prevent out-of-order elaboration in the
16817 back-end when stack checking is enabled..
16819 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16821 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
16822 result are the bounds of the left operand, not the right.
16824 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16827 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
16828 discriminant defaults.

16830 (Make_Component_List_Attributes): Ditto.
16832 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16833 Bob Duff <duff@adacore.com>
16835 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
16836 an association with a box as providing a value even though the
16837 initialization procedure for the type is not available.
16838 (Resolve_Record_Aggregate): Check that a choice of an association with a
16839 box corresponds to a component of the type.
16840 (Resolve_Record_Aggregate): Split Is_Abstract flag into
16841 Is_Abstract_Subprogram and Is_Abstract_Type.
16843 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
16846 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
16847 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
16848 called only when appropriate.

16895 the .ci files belonging to the projects, including binder generated
16897 (Non_VMS_Usage): Document that gnatstack accept project file switches.
16898 (GNATCmd): Update the B_Start variable if we are in a VMS environment.

16946 standard 8bits encoding.
16947 (WS2SU): As above but converting from wide-sring to string.
16948 This is needed as it is necessary to have access to both versions in the
16949 runtime for the form parameter encoding support.
16950 This set of patch add support for the encoding form parameter.
16951 (S2WS): Improve implementation to handle cases where the filename is not
16952 UTF-8 encoded. In this case we default to using the current code page
16953 for the conversion.

17001 __gnat_adjust_context_for_raise.
17002 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
17003 implementation of floating point operations as native x86 targets.
17004 So the FPU should be initialized in the same way using finit. Fix
17005 floating point operations accuracy issues.
17006 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
17007 member in struct sigaction, so as to avoid warning for incompatible

17197 Use First/Next_Component_Or_Discriminant
17198 (Analyze_Record_Representation_Clause):
17199 Use First/Next_Component_Or_Discriminant
17200 (Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
17201 (Analyze_Attribute_Definition_Clause, case Value_Size): Reject
17202 definition if type is unconstrained.
17203 (Adjust_Record_For_Reverse_Bit_Order): New procedure
17204 (Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
17205 Is_Abstract_Subprogram and Is_Abstract_Type.
17206 (Adjust_Record_For_Reverse_Bit_Order): New procedure
17208 * repinfo.adb (List_Record_Info): Use First/
17209 Next_Component_Or_Discriminant.
17211 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
17214 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
17215 Include -gnatyA in default switches
17217 * opt.ads: (Warn_On_Non_Local_Exception): New flag
17218 (Warn_On_Reverse_Bit_Order): New flag
17219 (Extensions_Allowed): Update the documentation.
17220 (Warn_On_Questionable_Missing_Parens): Now on by default
17222 * usage.adb: Add documentation of -gnatw.x/X switches
17223 Document new -gnatyA style switch
17224 -gnatq warnings are on by default
17226 2007-04-06 Ed Falis <falis@adacore.com>
17228 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
17229 full word is no longer compared twice.
17231 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17233 * sem_ch10.adb (Install_Limited_Context_Clauses.
17234 Expand_Limited_With_Clause): Use a new copy of selector name in the
17235 call to Make_With_Clause. This fixes the tree structure for ASIS
17236 purposes. Nothing is changed in the compiler behaviour.
17237 (Process_Body_Clauses): Handle properly use clauses whose prefix is
17238 a package renaming.
17239 (Install_Limited_With_Clauses): Do not install non-limited view when it
17240 is still incomplete.
17242 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17243 Gary Dismukes <dismukes@adacore.com>
17245 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
17246 when capturing size information, instead of base type, which for a
17247 formal array type will be the unconstrained type.
17248 (Analyze_Formal_Object_Declaration): Add check for illegal default
17249 expressions for a formal in object of a limited type.
17250 (Instantiate_Object): Ditto.
17251 (Check_Formal_Package_Instance): Skip entities that are formal objects,
17252 because they were defaulted in the formal package and no check applies
17254 (Check_Formal_Package_Instance): Extend conformance check to other
17255 discrete types beyond Integer.
17256 (Process_Default): Copy directly the unmatched formal. A generic copy
17257 has already been performed in Analyze_Formal_Package.
17258 (Analyze_Associations): If a formal subprogram has no match, check for
17259 partial parametrization before looking for a default, to prevent
17261 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
17262 not set the instantiation environment before analyzing the actuals.
17263 Fixes regression on 8515-003 with implementation of AI-133.
17264 Set_Instance_Env checks whether the generic unit is a predefined
17265 unit, in which case the instance must be analyzed with the latest Ada
17266 mode. This setting must take place after analysis of the actuals,
17267 because the actuals must be analyzed and frozen in the Ada mode extant
17268 outside of the current instantiation.
17269 (Save_Env, Restore_Env): Preserve and restore the configuration
17270 parameters so that predefined units can be compiled in the proper Ada
17272 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
17273 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
17274 and Is_Abstract_Type.
17275 (Analyze_Formal_Package): For better error recovery, Add exception
17276 handler to catch Instantion_Error, which can be raised in
17277 Analyze_Associations
17279 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17280 Bob Duff <duff@adacore.com>
17281 Gary Dismukes <dismukes@adacore.com>
17283 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
17284 prefix type is a discriminated subtype of the type of the formal.
17285 (Analyze_Allocator): Collect all coextensions regardless of the context.
17286 Whether they can be allocated statically is determined in exp_ch4.
17287 (Analyze_Selected_Component): If the prefix is a limited view and the
17288 non-limited view is available, use the non-limited one.
17289 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
17290 therefore illegal), suggest a qualified expression rather than a type
17291 conversion, because a type conversion would be illegal in this context.
17292 (Anayze_Allocator): Trace recursively all nested allocators so that all
17293 coextensions are on the corresponding list for the root. Do no mark
17294 coextensions if the root allocator is within a declaration for a stack-
17295 allocated object, because the access discriminants will be allocated on
17297 (Analyze_Call): Remove restriction on calls to limited functions for the
17298 cases of generic actuals for formal objects, defaults for formal objects
17299 and defaults for record components.
17300 (Analyze_Allocator): Before analysis, chain coextensions on the proper
17301 element list. Their expansion is delayed until the enclosing allocator
17302 is processed and its finalization list constructed.
17303 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
17304 for an operation with the given name among the primitive operations of
17305 the corresponding record type.
17306 (Analyze_Selected_Component): If the prefix is a task type that
17307 implements an interface, and there is no entry with the given name,
17308 check whether there is another primitive operation (e.g. a function)
17310 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
17311 properly the indexing of a function call written in prefix form, where
17312 the function returns an array type, and all parameters of the function
17313 except the first have defaults.
17314 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
17315 the original operands, rather than relocating them, for efficiency and
17316 to work properly when an operand is overloaded.
17317 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
17318 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
17319 (Analyze_Selected_Component): If the prefix is a private extension, only
17320 scan the visible components, not those of the full view.
17321 (Try_Primitive_Operation): If the operation is a procedure, collect all
17322 possible interpretations, as for a function, because in the presence of
17323 classwide parameters several primitive operations of the type can match
17324 the given arguments.
17326 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17327 Robert Dewar <dewar@adacore.com>
17329 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
17330 tag-indeterminate call to an abstract function, when the left-hand side
17332 (Analyze_Loop_Statement): Improve detection of infinite loops
17334 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17335 Thomas Quinot <quinot@adacore.com>
17337 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
17338 out of Analyze_Package_Declaration, because processing must be applied
17339 to package bodies as well, for deferred constants completed by pragmas.
17340 (Analyze_Package_Declaration): When the package declaration being
17341 analyzed does not require an explicit body, call Check_Completion.
17342 (May_Need_Implicit_Body): An implicit body is required when a package
17343 spec contains the declaration of a remote access-to-classwide type.
17344 (Analyze_Package_Body): If the package contains RACWs, append the
17345 pending subprogram bodies generated by exp_dist at the end of the body.
17346 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
17347 Is_Abstract_Subprogram and Is_Abstract_Type.
17348 (Preserve_Full_Attributes): The full entity list is not an attribute
17349 that must be preserved from full to partial view.
17351 * sem_dist.adb (Add_RAS_Dereference_TSS):
17352 Change primitive name to _Call so it cannot clash with any legal
17353 identifier, and be special-cased in Check_Completion.
17354 Mark the full view of the designated type for the RACW associated with
17355 a RAS as Comes_From_Source to get proper view switching when installing
17356 private declarations.
17357 Provite a placeholder nested package body along with the nested spec
17358 to have a place for Append_RACW_Bodies to generate the calling stubs
17359 and stream attributes.
17361 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17362 Robert Dewar <dewar@adacore.com>
17364 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
17365 that is a limited view, check the non-limited view if available.
17366 (Undefined): Refine error message for missing with of Text_IO
17367 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
17368 to distinguish real missing with cases.
17369 Fix format of all missing with messages
17370 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
17371 renaming as body when renamed entity is abstract.
17373 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17374 Javier Miranda <miranda@adacore.com>
17376 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
17377 predicate recursive, to handle complex expressions on literals whose
17378 spurious ambiguity comes from the abstract interpretation of some
17380 (Interface_Present_In_Ancestor): Add support to concurrent record
17382 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
17383 Is_Abstract_Subprogram and Is_Abstract_Type.
17385 2007-04-06 Ed Schonberg <schonberg@adacore.com>
17386 Javier Miranda <miranda@adacore.com>
17388 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
17389 dereference of a local object R created as a reference to another
17390 object O, use the access level of O.
17391 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
17392 rather than local Same_Formal_Type, to check whether protected operation
17393 overrides an inherited one.
17394 (Same_Formal_Type): New predicate, used when matching signatures of
17395 overriding synchronized operations, to handle the case when a formal
17396 has a type that is a generic actual.
17397 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
17398 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
17399 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
17400 syntactic ambiguities involving indexing of function calls that return
17402 (Abstract_Interface_List): New subprogram that returns the list of
17403 abstract interfaces associated with a concurrent type or a
17404 concurrent record type.
17405 (Interface_Present_In_Parent): New subprogram used to check if a
17406 given type or some of its parents implement a given interface.
17407 (Collect_Abstract_Interfaces): Add support for concurrent types
17408 with interface types.
17409 (Has_Abstract_Interfaces): Add support for concurrent types with
17411 (Is_Parent): New subprogram that determines whether E1 is a parent
17412 of E2. For a concurrent type its parent is the first element of its
17413 list of interface types; for other types this function provides the
17414 same result than Is_Ancestor.
17415 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
17416 (Collect_Synchronized_Interfaces): Removed because the subprogram
17417 Collect_Abstract_Interfaces provides this functionality.
17418 (Collect_Abstract_Interfaces): Minor update to give support to
17419 concurrent types and thus avoid undesired code duplication.
17420 (Get_Subprogram_Entity): Handle entry calls.
17421 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
17423 (Enter_Name): Do not give -gnatwh hiding warning for record component
17424 entities, they never result in hiding.

17431 of the enclosing object.
17432 Add N_Push and N_Pop nodes
17433 New field Exception_Label added
17434 (Local_Raise_Statements): New field in N_Exception_Handler_Node
17435 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
17436 (Is_Coextension): New flag for allocators, to mark allocators that
17437 correspond to access discriminants of dynamically allocated objects.
17438 (N_Block_Statement): Document the fact that the corresponding entity
17439 can be an E_Return_Statement.
17440 (Is_Coextension): New flag for allocators.
17441 Remove all code for DSP option

17449 before propagating exception.
17451 2007-04-06 Olivier Hainque <hainque@adacore.com>

17454 an address always within the call instruction from a return address.
17456 2007-04-06 Olivier Hainque <hainque@adacore.com>
17457 Eric Botcazou <botcazou@adacore.com>
17459 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
17460 expression with a COMPOUND_EXPR including the call instead of emitting
17461 the call directly here.
17462 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
17463 high bound is constant and the slice is empty. Tidy.
17464 (tree_transform, case N_Op_Not): Handle properly the case where the
17465 operation applies to a private type whose full view is a modular type.
17466 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
17467 Address_Clause, use the associated Expression as the GNAT tree
17468 representing the choice value to ensure the corresponding GCC tree is
17469 of the proper kind.
17470 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
17471 instead of just the operands, as the base GCC stabilize_reference does.
17472 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
17473 requested; otherwise fail.
17474 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

17479 implementation of UI_Div.
17480 (UI_Div): Reimplement as a call to UI_Div_Rem.
17481 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
17482 remainder, avoiding the cost of a multiplication and a subtraction.
17483 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
17484 provides both quotient and remainder in a single computation.
17485 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
17486 functions for uint.
17487 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
17488 is undefined if the given n is not inversible.
17490 2007-04-06 Olivier Hainque <hainque@adacore.com>

17499 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
17500 when updating the contents of the old pointer to an unconstrained array.
17501 (end_subprog_body): Set error_gnat_node to Empty.
17502 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

17734 (mainly static expression evaluation).
17735 Reword some continuation messages
17736 Add some \\ sequences to continuation messages
17737 (Resolve_Call): Refine infinite recursion case. The test has been

17751 during analysis, and use May_Be_Lvalue to distinguish read/write.
17752 (Valid_Array_Conversion): New procedure, abstracted from
17753 Valid_Conversion, to incorporate accessibility checks for arrays of
17754 anonymous access types.
17755 (Valid_Conversion): For a conversion to a numeric type occurring in an
17756 instance or inlined body, no need to check that the operand type is
17757 numeric, since this has been checked during analysis of the template.

18040 alignment of a field in a variant record might not be accurate. Add a
18041 safety test to make sure no alignment is set to a smaller value than
18042 the alignment of the field type.

18345 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
18346 assignments where the target subtype is unconstrained and the target
18347 object is a parameter or dereference (other aliased cases are known

18514 an aliased prefix must be known to be constrained in order to use True
18515 for the attribute value, and now it's possible for some aliased views

18529 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
18530 register in the final list objects containing class-wide interfaces;
18531 otherwise we incorrectly register the tag of the interface in the final
18533 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
18534 generate the wrapper if the parent primitive is abstract. This is
18535 required to report the correct error message.
18536 (Expand_N_Subtype_Indication): Do validity checks on range
18537 (Clean_Task_Names): If an initialization procedure includes a call to
18538 initialize a task (sub)component, indicate that the procedure will use
18539 the secondary stack.
18540 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
18541 compatibility for interfacing with CPP by default.
18542 (Expand_N_Object_Declaration): Only build an Adjust call when the
18543 object's type is a nonlimited controlled type.
18544 * exp_ch3.adb: Add with and use of Exp_Ch6.
18545 (Expand_N_Object_Declaration): Check for object initialization that is a
18546 call to build-in-place function and apply Make_Build_In_Place_Call_In_
18547 Object_Declaration to the call.
18548 (Freeze_Type): When the designated type of an RACW was not frozen at the
18549 point where the RACW was declared, validate the primitive operations
18550 with respect to E.2.2(14) when it finally is frozen.
18551 (Build_Initialization_Call,Expand_Record_Controller): Rename
18552 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
18553 return-by-reference has no meaning in Ada 2005.
18554 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
18555 to register tag of the immediate ancestor interfaces in the
18556 run-time structure.
18557 (Init_Secondary_Tags): Moved to the specification to allow the
18558 initialization of extension aggregates with abstract interfaces.
18559 (Build_Master_Renaming): Make public, for use by function declarations
18560 whose return type is an anonymous access type.
18561 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
18562 Insert_List_Before_And_Analyze after the generation of the specs
18563 associated with null procedures.
18564 (Expand_Tagged_Root): Update documentation in its specification.
18565 (Init_Secondary_Tags): Update documentation.
18566 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
18567 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
18568 then generate code to inherit the contents of the dispatch table
18569 directly from the ancestor.
18570 (Expand_Record_Controller): Insert controller component after tags of
18571 implemented interfaces.
18572 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
18573 create null procedure overridings when null procedures are inherited
18575 (Make_Null_Procedure_Specs): New procedure to generate null procedure
18576 declarations for overriding null primitives inherited from interfaces.
18577 (Is_Null_Interface_Procedure): New function in
18578 Make_Null_Procedure_Specs.
18579 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
18580 immediate ancestor of a tagged type is an abstract interface type we
18581 must generate the specification of the predefined primitives associated
18582 with controlled types (because the dispatch table of the ancestor is
18583 null and hence these entries cannot be inherited). This is required to
18584 elaborate well the dispatch table.

18592 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
18594 (Expand_N_In): Do validity checks on range
18595 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
18596 (Expand_N_Allocator): For "new T", if the object is constrained by
18597 discriminant defaults, allocate the right amount of memory, rather than
18598 the maximum for type T.
18599 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
18600 when the allocator is initialized by a build-in-place call, since the
18601 allocator is already rewritten as a reference to the function result,
18602 and this prevents an unwanted duplication of the function call.
18603 Add with and use of Exp_Ch6.
18604 (Expand_Allocator_Expresssion): Check for an allocator whose expression
18605 is a call to build-in-place function and apply
18606 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
18607 untagged designated types).
18608 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
18609 optimization if source or target is biased.
18610 (Expand_N_Allocator): Add comments for case of an allocator within a
18611 function that returns an anonymous access type designating tasks.
18612 (Expand_N_Allocator): apply discriminant checks for access
18613 discriminants of anonymous access types (AI-402, AI-416)

18620 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
18622 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
18623 (Expand_N_Assignment_Statement): Call
18624 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
18625 build-in-place function call. Currently, this can happen only for
18626 assignments that come from aggregates.
18627 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18628 in order to alleviate the upward compatibility introduced by AI-318.
18629 (Expand_N_Extended_Return_Statement): Add support for handling the
18630 return object as a build-in-place result.
18631 (Expand_Non_Function_Return): Implement simple return statements nested
18632 within an extended return.
18633 (Enable_New_Return_Processing): Turn on the new processing of return
18635 (Expand_Non_Function_Return): For a return within an extended return,
18636 don't raise Program_Error, because Sem_Ch6 now gives a warning.
18637 (Expand_N_Extended_Return_Statement): Implement AI-318
18638 (Expand_Simple_Function_Return): Ditto.
18639 (Expand_N_If_Statement): Handle new -gnatwt warning
18640 (Expand_N_Case_Statement): Handle new -gnatwt warning
18641 (Expand_N_Assignment): Handle assignment to the Priority attribute of
18642 a protected object.
18643 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
18644 validity checking of assignments to elementary record components.
18645 (Expand_N_Return_Statement): return Class Wide types on the secondary
18646 stack independantly of their controlled status since with HIE runtimes,
18647 class wide types are not potentially controlled anymore.
18649 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
18652 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
18653 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
18654 it expects a block, procedure, or task. The return statement will get
18655 turned into a block, and Expand_Cleanup_Actions will happen then.

18659 Bob Duff <duff@adacore.com>
18660 Gary Dismukes <dismukes@adacore.com>
18662 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
18664 (Expand_Inlined_Call): Tagged types are by-reference types, and
18665 therefore should be replaced by a renaming declaration in the expanded
18666 body, as is done for limited types.
18667 (Expand_Call): If this is a call to a function with dispatching access
18668 result, propagate tag from context.
18669 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
18671 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
18672 build-in-place when the right-hand side of an assignment is a
18673 build-in-place function call.
18674 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
18675 of the explicit dereference of the allocator to the result subtype of
18676 the build-in-place function. This is needed to satisfy type checking
18677 in cases where the caller's return object is created by an allocator for
18678 a class-wide access type and the type named in the allocator is a
18680 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
18681 conversion of the reference to the declared object to the result subtype
18682 of the build-in-place function. This is needed to satisfy type checking
18683 in cases where the declared object has a class-wide type. Also, in the
18684 class-wide case, change the type of the object entity to the specific
18685 result subtype of the function, to avoid passing a class-wide object
18686 without explicit initialization to the back end.
18687 (Register_Interface_DT_Entry): Moved outside the body of
18688 Freeze_Subprogram because this routine is now public; it is called from
18689 Check_Dispatching_Overriding to handle late overriding of abstract
18690 interface primitives.
18691 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
18692 adding an implicit access actual on a call to a build-in-place function.
18693 (Expand_Actuals): Test for an actual parameter that is a call to a
18694 build-in-place function and apply
18695 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
18696 (Is_Build_In_Place_Function): New function to determine whether an
18697 entity is a function whose calls should be handled as build-in-place.
18698 (Is_Build_In_Place_Function_Call): New function to determine whether an
18699 expression is a function call that should handled as build-in-place.
18700 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
18701 calls to build-in-place functions as the initialization of an allocator.
18702 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
18703 handling calls to build-in-place functions in contexts that do not
18704 involve init of a separate object (for example, actuals of subprogram
18706 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
18707 handling calls to build-in-place functions as the initialization of an
18708 object declaration.
18709 (Detect_Infinite_Recursion): Add explicit parameter Process to
18710 instantiation of Traverse_Body to avoid unreferenced warning.
18711 (Check_Overriding_Inherited_Interfaces): Removed.
18712 (Register_Interface_DT_Entry): Code cleanup.
18713 (Register_Predefined_DT_Entry): Code cleanup.
18714 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18715 inlined statements if within a transient scope.
18716 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18717 formal parameters with occurrences of actuals in inlined body, establish
18718 visibility on the proper view of the actual's subtype for the body's
18720 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18721 compatibility mode and we have an imported CPP subprogram because
18722 for now we assume that imported CPP primitives correspond with
18723 objects whose constructor is in the CPP side (and therefore we
18724 don't need to generate code to register them in the dispatch table).
18725 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18726 aligned selected component.
18727 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18728 the actual of an in-mode parameter is a type conversion.
18729 (Expand_Actuals): If the call does not come from source and the actual
18730 is potentially misaligned, let gigi handle it rather than rejecting the
18731 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18732 Class Wide types as returning by reference independantly of their
18733 controlled status since with HIE runtimes class wide types are not
18734 potentially controlled anymore.
18736 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18738 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
18739 references that are private components of the protected object.
18740 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
18741 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18742 instantiation to deal with warnings.
18743 (Initialize_Protection): If expression for priority is non-static, use
18744 System_Priority as its expected type, in case the expression has not
18747 2006-10-31 Robert Dewar <dewar@adacore.com>
18749 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18750 initialization of Homonym_Len.
18751 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18752 names from fully qualified name. Fixes problem of duplicate
18753 external names differing only in the presence of such a block name.
18755 2006-10-31 Thomas Quinot <quinot@adacore.com>
18756 Pablo Oliveira <oliveira@adacore.com>
18758 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18759 subprogram Ids, even if they are not yet assigned.
18760 (Build_Subprogram_Id): It is now this function that will take care of
18761 calling Assign_Subprogram_Ids if necessary.
18762 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18763 should be done only once they are assigned.
18764 (Build_From_Any_Function, case of tagged types): Add missing call to
18766 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18767 type for an RACW type.
18768 (Add_RACW_Features): When processing an RACW declaration for which the
18769 designated type is already frozen, enforce E.2.2(14) rules immediately.
18770 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18771 special reordering of controlling formals.
18773 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18774 associated stub type for an RACW type.
18776 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18778 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18779 fixed-point operations in an integer context, i.e. as operands of a
18780 conversion to an integer type, indicate that result must be rounded.
18782 2006-10-31 Robert Dewar <dewar@adacore.com>
18784 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18785 cases, pass the encoding method, since it is now required by the run
18788 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18789 assumption that Str'First = 1.
18790 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18791 it on to the Value_Wide_Wide_Character call.
18792 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18793 properly handles a string of the form quote-encoded_wide_char-quote.
18795 * s-wchcnv.adb: Minor reformatting
18797 2006-10-31 Javier Miranda <miranda@adacore.com>
18799 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18800 run-time membership test to ensure that the constructed object
18801 implements the target abstract interface.
18803 2006-10-31 Robert Dewar <dewar@adacore.com>
18805 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18806 Machine_Attribute pragma internally to implement the user pragma.
18807 Add processing for pragma Interface so that it is now completely
18808 equivalent to pragma Import.
18810 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18811 so that it can be applied to all entities, including record components
18812 and enumeration literals.
18813 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18814 priority ranges are correct, verify compatibility against task
18815 dispatching and locking policies, and if everything is correct an entry
18816 is added to the table containing priority specific dispatching entries
18817 for this compilation unit.
18818 (Delay_Config_Pragma_Analyze): Delay processing
18819 Priority_Specific_Dispatching pragmas because when processing the
18820 pragma we need to access run-time data, such as the range of
18821 System.Any_Priority.
18822 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18823 Allow pragma Unreferenced as a context item
18824 Add pragma Preelaborable_Initialization
18825 (Analyze_Pragma, case Interface): Interface is extended so that it is
18826 now syntactically and semantically equivalent to Import.
18827 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18828 insertion characters.
18829 Add handling for Pragma_Wide_Character_Encoding
18830 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18831 never supercedes a real restriction, and that a real restriction
18832 always supercedes a warning.
18833 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

18840 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18841 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18842 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18844 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18845 type of the function containing a return statement, because the
18846 Return_Type field was removed. We now use the Return_Applies_To field.
18848 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18849 (Build_Task_Image_Decl): If procedure is not called from an
18850 initialization procedure, indicate that function that builds task name
18851 uses the sec. stack. Otherwise the enclosing initialization procedure
18852 will carry the indication.
18853 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18854 N_Object_Declaration instead.
18855 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18856 conditional dead code killed, and change implementation accordingly.
18857 (Insert_Actions): Add N_Return_Object_Declaration case.
18858 Correct comment to mention N_Extension_Aggregate node.
18859 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18860 attempts to save information for global variables which cannot be
18862 (Get_Current_Value_Condition): Handle conditions the other way round
18863 (constant on left). Also handle right operand of AND and AND THEN
18864 (Set_Current_Value_Condition): Corresponding changes
18865 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18866 (Get_Current_Value_Condition): Handle simple boolean operands
18867 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18868 (Get_Current_Value_Condition): If the variable reference is within an
18869 if-statement, does not appear in the list of then_statments, and does
18870 not come from source, treat it as being at unknown location.
18871 (Get_Current_Value_Condition): Enhance to allow while statements to be
18872 processed as well as if statements.
18873 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18875 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18876 of loop. This is safe now that we fixed Kill_Current_Values.
18877 (OK_To_Do_Constant_Replacement): Check whether current scope is
18878 Standard, before examining outer scopes.
18880 2006-10-31 Vincent Celier <celier@adacore.com>
18882 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18883 When True, apply VMS treatment to children of packages A, G, I and S.
18886 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18888 2006-10-31 Robert Dewar <dewar@adacore.com>
18889 Ed Schonberg <schonberg@adacore.com>
18891 * freeze.adb: Add handling of Last_Assignment field
18892 (Warn_Overlay): Supply missing continuation marks in error msgs
18893 (Freeze_Entity): Add check for Preelaborable_Initialization
18895 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18897 * g-expect.adb: Add Warnings (Off) to prevent new warning

18900 (Generate_Reference): Centralize handling of pragma Obsolescent here
18901 (Generate_Reference): Accept an implicit reference generated for a
18902 default in an instance.
18903 (Generate_Reference): Accept a reference for a node that is not in the
18904 main unit, if it is the generic body corresponding to an subprogram
18907 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18909 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18911 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18913 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18914 use clauses, to avoid messages on packages used to qualify, and also
18915 to avoid messages from obsolescent units.
18916 (Warn_On_Useless_Assignments): Don't generate messages for imported
18917 and exported variables.
18918 (Warn_On_Useless_Assignments): New procedure
18919 (Output_Obsolescent_Entity_Warnings): New procedure
18920 (Check_Code_Statement): New procedure
18922 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18923 Change name Is_Ada_2005 to Is_Ada_2005_Only
18924 (Last_Assignment): New field for useless assignment warning
18926 2006-10-31 Olivier Hainque <hainque@adacore.com>
18928 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18929 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18931 2006-10-31 Bob Duff <duff@adacore.com>
18932 Robert Dewar <dewar@adacore.com>
18933 Ed Schonberg <schonberg@adacore.com>
18935 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18936 Ada 95 mode, because it violates the new rules for AI-318.
18938 * g-awk.ads: Use overloaded subprograms in every case where we used to
18939 have a default of Current_Session. This makes the code closer to be
18940 correct for both Ada 95 and 2005.
18942 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18943 code, relying on the fact that the compiler generates a warning
18944 instead of an error in -gnatg mode.
18946 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18947 E_Return_Statement entity kind.
18948 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18950 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18951 report an error if the reserved word abstract has been previously found.
18952 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18954 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18955 parenthesized range attribute usage
18956 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18958 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18959 in the syntax for extended_return_statement. This is not in the latest
18960 RM, but the ARG is expected to issue an AI allowing this.
18961 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18962 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18963 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18964 P_Return_Statement): Parse the new syntax for extended_return_statement.
18966 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18967 Output_End_Missing): Add error-recovery code for the new
18968 extended_return_statement syntax; that is, the new E_Return entry on
18971 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18972 limited to nonlimited, because otherwise we violate the new Ada 2005
18973 rules about returning limited types in function Create_AST_Handler in
18976 * sem.adb (Analyze): Add cases for new node kinds
18977 N_Extended_Return_Statement and N_Return_Object_Declaration.
18979 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18980 type is in the same category as type of context before applying check,
18981 to prevent anomalies in instantiations.
18982 (Resolve_Aggregate): Remove test for limited components in aggregates.
18983 It's unnecessary in Ada 95, because if it has limited components, then
18984 it must be limited. It's wrong in Ada 2005, because limited aggregates
18986 (Resolve_Record_Aggregate): Move check for limited types later, because
18987 OK_For_Limited_Init requires its argument to have been resolved.
18988 (Get_Value): When copying the component default expression for a
18989 defaulted association in an aggregate, use the sloc of the aggregate
18990 and not that of the original expression, to prevent spurious
18991 elaboration errors, when the expression includes function calls.
18992 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18993 were missing. We also didn't handle qualified expressions. Now also
18994 allow function calls. Use new common routine OK_For_Limited_Init.
18995 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18996 with space can upper case letter).
18998 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18999 Has_Static_Discriminants flag
19000 (Record_Type_Declaration): Diagnose an attempt to declare an interface
19001 type with discriminants.

19003 (Build_Discriminant_Constraints): Use updated form of
19004 Denotes_Discriminant.
19005 (Process_Subtype): If the subtype is a private subtype whose full view
19006 is a concurrent subtype, introduce an itype reference to prevent scope
19008 (Build_Derived_Record_Type, Collect_Interface_Primitives,
19009 Record_Type_Declaration): The functionality of the subprograms
19010 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
19011 is now performed by a single routine.
19012 (Build_Derived_Record_Type): If the type definition includes an explicit
19013 indication of limitedness, then the type must be marked as limited here
19014 to ensure that any access discriminants will not be treated as having
19015 a local anonymous access type.
19016 (Check_Abstract_Overriding): Issue a detailed error message when an
19017 abstract subprogram was not overridden due to incorrect mode of its
19019 (Analyze_Private_Extension_Declaration): Add support for the analysis of
19020 synchronized private extension declarations. Verify that the ancestor is
19021 a limited or synchronized interface or in the generic case, the ancestor
19022 is a tagged limited type or synchronized interface and all progenitors
19023 are either limited or synchronized interfaces.
19024 Derived_Type_Declaration): Check for presence of private extension when
19025 dealing with synchronized formal derived types.
19026 Process_Full_View): Enchance the check done on the usage of "limited" by
19027 testing whether the private view is synchronized.
19028 Verify that a synchronized private view is completed by a protected or
19030 (OK_For_Limited_Init_In_05): New function.
19031 (Analyze_Object_Declaration): Move check for limited types later,
19032 because OK_For_Limited_Init requires its argument to have been resolved.
19033 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
19034 in order to alleviate the upward compatibility introduced by AI-318.
19035 (Constrain_Corresponding_Record): If the constraint is for a component
19036 subtype, mark the itype as frozen, to avoid out-of-scope references to
19037 discriminants in the back-end.
19038 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
19039 this subprogram against wrong sources.
19040 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
19041 discriminant of limited type completed with a protected type, when the
19042 discriminant is used to constrain a private component of the type, and
19043 expansion is disabled.
19044 (Find_Type_Of_Object): Do not treat a return subtype that is an
19045 anonymous subtype as a local_anonymous_type, because its accessibility
19046 level is the return type of the enclosing function.
19047 (Check_Initialization): In -gnatg mode, turn the error "cannot
19048 initialize entities of limited type" into a warning.
19049 (OK_For_Limited_Init): Return true for generated nodes, since it
19050 sometimes violates the legality rules.
19051 (Make_Incomplete_Declaration): If the type for which an incomplete
19052 declaration is created happens to be the currently visible entity,
19053 preserve the homonym chain when removing it from visibility.
19054 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
19055 inherited subprograms.
19056 (Access_Definition): If this is an access to function that is the return
19057 type of an access_to_function definition, context is a type declaration
19058 and the scope of the anonymous type is the current one.
19059 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
19060 incomplete subtype to the set of private dependents of the original
19062 (Constrain_Discriminated_Type): Emit an error message whenever an
19063 incomplete subtype is being constrained.
19064 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
19065 corresponding subtype of the full view of the original incomplete type.
19066 (Check_Incomplete): Properly detect invalid usage of incomplete types

19080 Robert Dewar <dewar@adacore.com>
19082 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
19083 handling executable extension manually and duplicating code.
19085 * make.adb: Implement new -S switch
19086 (Gnatmake): Use new function Osint.Executable_Name instead
19087 of handling executable extension manually.
19089 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
19090 is specified, the executable name ends with this suffix.
19091 Take advantage of Osint.Executable_Name instead of duplicating code.
19093 * switch-m.adb: Recognize new gnatmake -S switch
19095 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
19097 (Get_Target_Parameters): Set Executable_Extension_On_Target if

19102 2006-10-31 Vincent Celier <celier@adacore.com>
19104 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
19105 call it with -static-libgcc, as there are some platforms, such as
19106 Darwin, where one of these two switches is compulsory to link.
19108 2006-10-31 Vincent Celier <celier@adacore.com>
19110 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
19111 instead of ADA_PROJECT_PATH, for the project path.
19112 (Gnatls): When displaying the project path directories, use host dir
19115 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
19116 names in the project path, as absolute paths may correspond to
19117 multi-valued VMS logical names.
19119 2006-10-31 Vincent Celier <celier@adacore.com>
19121 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an

19124 (Change_Dir): Remove, no longer used
19125 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
19126 on Windows. Get it calling Get_Current_Dir.

19128 (Normalize_Pathname)[VMS]: Do not resolve directory names.
19129 (Pid_To_Integer): New function to convert a Process_Id to Integer
19131 2006-10-31 Thomas Quinot <quinot@adacore.com>
19133 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
19134 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
19136 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
19139 2006-10-31 Robert Dewar <dewar@adacore.com>

19148 2006-10-31 Robert Dewar <dewar@adacore.com>
19150 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
19152 (Layout_Variant_Record): Retrieve the discriminants from the entity
19153 rather than from the type definition, because in the case of a full
19154 type for a private type we need to take the discriminants from the
19156 (Layout_Component_List): When applying the Max operator to variants with
19157 a nonstatic size, check whether either operand is static and scale that
19158 operand from bits to storage units before applying Max.
19159 (Layout_Type): In VMS, if a C-convention access type has no explicit
19160 size clause (and does not inherit one in the case of a derived type),
19161 then the size is reset to 32 from 64.
19163 2006-10-31 Vincent Celier <celier@adacore.com>
19165 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
19166 its file has already been loaded, according to the unit being loaded,
19167 not to the current value of Multiple_Unit_Index.
19169 2006-10-31 Thomas Quinot <quinot@adacore.com>
19170 Eric Botcazou <ebotcazou@adacore.com>

19202 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
19205 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19207 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
19208 Process_Body_Clauses): If the context of a body includes a use clause
19209 for P.Q then a with_clause for P in the same body is not redundant,
19210 even if the spec also has a with_clause on P.
19211 Add missing continuation mark to error msg
19212 (Build_Limited_Views): A limited view of a type is tagged if its
19213 declaration includes a record extension.
19214 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
19215 node, even if the subunit has errors. This avoids malfunction by
19216 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
19217 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
19218 generation of obsolescent messages for with statements (cannot do
19219 this too early, or we cannot implement avoiding the messages in the
19220 case of obsolescent units withing obsolescent units).
19221 (Install_Siblings): If the with_clause is on a remote descendant of
19222 an ancestor of the current compilation unit, find whether there is
19223 a sibling child unit that is immediately visible.
19224 (Remove_Private_With_Clauses): New procedure, invoked after completing
19225 the analysis of the private part of a nested package, to remove from
19226 visibility the private with_clauses of the enclosing package
19228 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
19229 now centralized in Generate_Reference.
19230 (Install_Limited_Context_Clauses): Remove superfluous error
19231 message associated with unlimited view visible through use
19232 and renamings. In addition, at the point in which the error
19233 is reported, we add the backslash to the text of the error
19234 to ensure that it is reported as a single error message.
19235 Use new // insertion for some continuation messages
19236 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
19237 to create implicit with_clause for parent unit mentioned in original
19238 limited_with_clause.
19239 (Install_Limited_With_Unit): Set entity of parent identifiers if the
19240 unit is a child unit. For ASIS queries.
19241 (Analyze_Subunit): If the subunit appears within a child unit, make all
19242 ancestor child units directly visible again.

19257 a formal object declaration with an access definition or a subtype mark
19258 with a null exclusion.
19259 (P_Generic_Association): Handle association with box, and others_choice
19260 with box, to support Ada 2005 partially parametrized formal packages.
19262 2006-10-31 Robert Dewar <dewar@adacore.com>
19263 Javier Miranda <miranda@adacore.com>
19265 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
19266 (P_Type_Declaration): Remove barrier against the reserved word "limited"
19267 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
19268 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
19269 private extensions.
19270 (P_Type_Declaration): Add the new actual Abstract_Present to every call
19271 to P_Interface_Type_Definition.

19273 if the reserved word abstract has been previously found.
19274 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
19275 object renaming declaration with an access definition or subtype mark
19276 with a possible null exclusion.

19298 2006-10-31 Vincent Celier <celier@adacore.com>
19300 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
19301 on VMS, change "__" to '.' before checking the name.
19302 (Record_Ada_Source): Always add the source file name in the list of
19303 of sources, even if it is not the first time, as it is for another
19305 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
19306 dot, instead of replacing only the first '_'.
19308 * prj-part.adb (Parse): Convert project file path to canonical form
19310 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
19311 extended, the project id of the project extending it is recorded in its
19312 data, even when it has already been processed as an imported project.
19314 2006-10-31 Robert Dewar <dewar@adacore.com>
19316 * repinfo.adb (List_Entities): Don't list entities from renaming

19320 Robert Dewar <dewar@adacore.com>
19322 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
19323 only a restriction warning is active for the given restriction. This is
19324 desirable because we do not want to modify code in the case where only
19326 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
19327 causes overriding of real restrictions.
19328 Take advantage of new No_Restrictions constant.
19330 * raise.h: (__gnat_set_globals): Change profile.
19332 2006-10-31 Arnaud Charlet <charlet@adacore.com>

19360 attribute whose prefix is the type of an enclosing aggregate.
19361 Generalizes previous mechanism to handle attribute references nested
19362 arbitrarily deep within the aggregate.
19363 (Analyze_Access_Attribute): An access attribute whose prefix is a type
19364 can appear in an aggregate if this is a default-initialized aggregate
19365 for a self-referential type.
19366 (Resolve_Attribute, case Access): Ditto.
19367 Add support for new implementation defined attribute Stub_Type.
19368 (Eval_Attribute, case Attribute_Stub_Type): New case.
19369 (Analyze_Attribute, case Attribute_Stub_Type): New case.
19370 (Stream_Attribute_Available): Implement using new subprogram from

19372 Has_Specified_Stream_Attribute flag.
19373 Disallow Storage_Size and Storage_Pool for access to subprogram
19374 (Resolve_Attribute, case 'Access et al): Take into account anonymous
19375 access types of return subtypes in extended return statements. Remove
19376 accessibility checks on anonymous access types when Unchecked_Access is

19379 a class-wide interface to a tagged type.
19380 Add support for the attribute Priority.
19381 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
19382 whether the designated type is discriminated with a constrained partial
19383 view and require static matching in that case.
19384 Add local variable Des_Btyp. The Designated_Type
19385 of an access to incomplete subtype is either its non-limited view if
19386 coming from a limited with or its etype if regular incomplete subtype.
19388 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
19389 Fix predicate to identify and allow cases of (expander-generated)
19390 references to tag of designated object of a RACW.
19391 (Validate_Static_Object_Name): In Ada 2005, a formal object is
19392 non-static, and therefore cannot appear as a primary in a preelaborable

19395 Has_Read_Write_Attributes.
19396 (Has_Read_Write_Attributes): Reimplement in termes of

19400 (remove guard checking for Is_Record_Type / Is_Access_Type).
19402 2006-10-31 Robert Dewar <dewar@adacore.com>
19404 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
19405 useless assignments here and conditionalize it on absence of exception
19407 (Analyze_Exception_Handlers): Small code reorganization of error
19408 detection code, for new handling of formal packages.

19421 synchronized formal derived type is a synchronized tagged type.
19422 (Instantiate_Formal_Package): When creating the instantiation used to
19423 validate the actual package of a formal declared without a box, check
19424 whether the formal itself depends on a prior actual.
19425 (Instantiate_Formal_Subprogram): Create new entities for the defining
19426 identifiers of the formals in the renaming declaration, for ASIS use.
19427 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
19428 a renaming declaration or a subtype declaration for an actual in an
19429 instance, capture location information of declaration in generic, for
19431 (Instantiate_Formal_Package): Add comments on needed additional tests.
19432 AI-317 (partial parametrization) is fully implemented.
19433 (Validate_Private_Type_Instance): Add check for actual which
19434 must have preelaborable initialization
19435 Use new // insertion for some continuation messages
19436 (Analyze_Formal_Object_Declaration): Change usage of Expression to
19437 Default_Expression. Add type retrieval when the declaration has an
19438 access definition. Update premature usage of incomplete type check.
19439 (Check_Access_Definition): New subsidiary routine. Check whether the
19440 current compilation version is Ada 05 and the supplied node has an
19442 (Instantiate object): Alphabetize local variables. Handle the creation
19443 of new renaming declarations with respect to the kind of definition
19444 used - either an access definition or a subtype mark. Guard against
19445 unnecessary error message in the context of anonymous access types after
19446 they have been resolved. Add check for required null exclusion in a
19447 formal object declaration.
19448 (Switch_View): A private subtype of a non-private type needs to be
19449 switched (the base type can have been switched without its private
19450 dependents because of the last branch of Check_Private_View.
19451 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
19453 (Instantiate_Type): Emit an error message whenever a class-wide type of
19454 a tagged incomplete type is used as a generic actual.
19455 (Find_Actual_Type): Extend routine to handle a component type in a child
19456 unit that is imported from a formal package in a parent.
19457 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
19458 agree on constrainedness, rather than checking against ultimate ancestor
19459 (Instantiate_Subprogram_Body): Create a cross-reference link to the
19460 generic body, for navigation purposes.

19463 Thomas Quinot <quinot@adacore.com>
19465 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
19467 (New_Stream_Subprogram): When processing an attribute definition clause
19468 for a stream-oriented subprogram, record an entity node occurring at
19469 the point of clause to use for checking the visibility of the clause,
19470 as defined by 8.3(23) as amended by AI-195.
19471 (New_Stream_Subprogram): New procedure, factoring behaviour from both
19472 New_Stream_Function and New_Stream_Procedure.
19473 (New_Stream_Function, New_Stream_Procedure): Removed.
19474 (Analyze_Attribute_Definition_Clause, case Address): Check new
19475 Alignment_Check check

19478 Javier Miranda <miranda@adacore.com>
19479 Robert Dewar <dewar@adacore.com>
19481 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
19482 generate the same errors compiling under -gnatc.
19483 (Try_Object_Operation): If no candidate interpretation succeeds, but
19484 there is at least one primitive operation with the right name, report
19485 error in call rather than on a malformed selected component.
19486 (Analyze_Selected_Component): If the prefix is an incomplete type from
19487 a limited view, and the full view is available, use the full view to
19488 determine whether this is a prefixed call to a primitive operation.
19489 (Operator_Check): Verify that a candidate interpretation is a binary
19490 operation before checking the type of its second formal.
19491 (Analyze_Call): Add additional warnings for function call contexts not
19493 (Analyze_Allocator): Move the check for "initialization not allowed for
19494 limited types" after analyzing the expression. This is necessary,
19495 because OK_For_Limited_Init looks at the structure of the expression.
19496 Before analysis, we don't necessarily know what sort of expression it
19497 is. For example, we don't know whether F(X) is a function call or an
19498 indexed component; the former is legal in Ada 2005; the latter is not.
19499 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
19500 were missing. We also didn't handle qualified expressions. Now also
19501 allow function calls. Use new common routine OK_For_Limited_Init.
19502 (Analyze_Type_Conversion): Do not perform some legality checks in an
19503 instance, because the error message will be redundant or spurious.
19504 (Analyze_Overloaded_Selected_Component): Do not do style check when
19505 setting an entity, since we do not know it is the right entity yet.
19506 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
19507 (Analyze_Overloaded_Selected_Component): Same change
19508 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
19509 since regular incomplete subtypes are transformed into corresponding
19510 subtypes of their full views.
19511 (Complete_Object_Operation): Treat name of transformed subprogram call
19512 as coming from source, for browsing purposes.
19513 (Try_Primitive_Operation): If formal is an access parameter, compare
19514 with base type of object to determine whether it is a primitive
19516 (Operator_Check): If no interpretation of the operator matches, check
19517 whether a use clause on any candidate might make the operation legal.
19518 (Try_Class_Wide_Operation): Check whether the first parameter is an
19519 access type whose designated type is class-wide.

19525 * sem_ch5.ads, sem_ch5.adb (Analyze_Loop_Statement): Add circuit to
19526 warn on infinite loops.
19527 Add \\ to some continuation messages
19528 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
19529 (Process_Bounds): If the bounds are integer literals that result from
19530 constant-folding, and they carry a user-defined type, preserve that type
19531 rather than treating this as an integer range.
19532 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
19533 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
19534 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
19535 left hand side of assignment.
19536 (Analyze_Assignment): Add suport to manage assigments to the attribute
19537 priority of a protected object.
19538 (Check_Possible_Current_Value_Condition): Allow fully qualified names
19539 not just identifiers.
19540 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
19541 or AND THEN for possible tracking.
19542 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
19543 case of while loops so we can track values in the loop body.
19545 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19546 Hristian Kirtchev <kirtchev@adacore.com>
19547 Bob Duff <duff@adacore.com>
19549 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
19550 procedure cannot be a protected operation (it is a basic_declaration,
19551 not a subprogram_declaration).
19552 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
19553 Subp. Add logic for entry processing.
19554 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
19555 Determine whether an entry or subprogram of a protected or task type
19556 override an inherited primitive of an implemented interface.
19557 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
19558 Update the actual used in calls to Check_Overriding_Indicator.
19559 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
19560 generate the proper reference to the parent unit, for cross-reference.
19561 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
19563 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
19564 (Add_Extra_Formal): Revise procedure to allow passing in associated
19565 entity, scope, and name suffix, and handle setting of the new
19566 Extra_Formals field.
19567 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
19568 pass new parameters. Add support for adding the new extra access formal
19569 for functions whose calls are treated as build-in-place.
19570 (Analyze_A_Return_Statement): Correct casing in error message.
19571 Move Pop_Scope to after Analyze_Function_Return, because an extended
19572 return statement really is a full-fledged scope. Otherwise, visibility
19573 doesn't work right. Correct use of "\" for continuation messages.
19574 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
19575 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
19576 the node doesn't get properly marked as analyzed.
19577 (Analyze_Subprogram_Body): If subprogram is a function that returns
19578 an anonymous access type that denotes a task, build a Master Entity
19580 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
19581 proper usage of null exclusion in a result definition.
19582 (Process_Formals): Code cleanup and new error message.
19583 (Process_Formals): Detect incorrect application of null exclusion to
19585 (Conforming_Types): Handle conformance between [sub]types and itypes
19586 generated for entities that have null exclusions applied to them.
19587 (Maybe_Primitive_Operation): Add an additional type retrieval when the
19588 base type is an access subtype. This case arrises with null exclusions.
19589 (New_Overloaded_Entity): Do not remove the overriden entity from the
19590 homonym chain if it corresponds with an abstract interface primitive.
19591 (Process_Formals): Replace membership test agains Incomplete_Kind with a
19592 call to the synthesized predicate Is_Incomplete_Type.
19593 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
19595 (Analyze_Subprogram_Declaration): Check that abstract interface
19596 primitives are abstract or null.
19597 (Analyze_Subprogram_Specification): Remove previous check for abstract
19598 interfaces because it was not complete.
19599 (Has_Interface_Formals): Removed.
19601 2006-10-31 Ed Schonberg <schonberg@adacore.com>
19602 Javier Miranda <miranda@adacore.com>
19604 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
19605 of Analyze_Package_Body, to create Itype references for anonymous
19606 access types created in the package declaration, whose designated types
19607 may have only a limited view.
19608 (Analyze_Package_Specification): For the private part of a nested
19609 package, install private_with_clauses of enclosing compilation unit if
19610 we are in its visible part.
19611 (Declare_Inherited_Private_Subprograms): Complete barrier
19612 to ensure that the primitive operation has an alias to some parent
19613 primitive. This is now required because, after the changes done for the
19614 implementation of abstract interfaces, the contents of the list of
19615 primitives has entities whose alias attribute references entities of
19616 such list of primitives.
19617 (Analyze_Package_Specification): Simplify code that handles parent units
19618 of instances and formal packages.
19619 (Uninstall_Declarations): Check the convention consistency among
19620 primitive overriding operations of a tagged record type.

19624 Javier Miranda <miranda@adacore.com>
19625 Ed Schonberg <schonberg@adacore.com>
19627 * sem_ch8.adb: Minor error msg rewording
19628 (Undefined): When checking for misspellings, invert arguments (to get
19629 expected and found set right)
19630 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
19631 (Analyze_Generic_Renaming): Same fix
19632 (Use_One_Package): Do not take into account the internal entities of
19633 abstract interfaces during the analysis of entities that are marked
19634 as potentially use-visible.
19635 (Find_Type): Handle the case of an attribute reference for
19636 implementation defined attribute Stub_Type (simply let the analysis of
19637 the attribute reference rewrite it).
19638 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
19639 type that appears in a Use_Type clause.
19640 (Analyze_Object_Renaming): Add support for renaming of the Priority
19642 (Find_Type): In Ada 2005, a task type can be used within its own body,
19643 when it appears in an access definition.
19644 (Analyze_Object_Renaming): Remove warning on null_exclusion.
19645 (Analyze_Object_Renaming): Introduce checks for required null exclusion
19646 in a formal object declaration or in a subtype declaration.
19647 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
19648 (Check_Null_Exclusion): New local routine to
19649 Analyze_Subprogram_Renaming. Check whether the formals and return
19650 profile of a renamed subprogram have required null exclusions when
19651 their counterparts of the renaming already impose them.
19652 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
19653 Determine whether an entity is inside a generic scope.
19654 (In_Open_Scope): First pass of documentation update.
19655 (Find_Expanded_Name): Add support for shadow entities associated with
19656 limited withed packages. This is required to handle nested packages.
19657 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
19658 that makes a renaming of a limited withed package illegal.
19660 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
19661 Ed Schonberg <schonberg@adacore.com>
19663 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
19664 Check_Overriding_Indicator.
19665 (Analyze_Task_Definition): Ditto.
19666 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
19667 (Check_Overriding_Indicator): To find overridden interface operation,
19668 examine only homonyms that have an explicit subprogram declaration, not
19669 inherited operations created by an unrelated type derivation.
19670 (Check_Overriding_Indicator): When checking for the presence of "null"
19671 in a procedure, ensure that the queried node is a procedure
19673 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
19674 type when the formal is an access to variable.
19675 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
19676 (Analyze_Task_Type): Same addition
19677 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
19678 provide navigation capabilities for entries.

19683 Gary Dismukes <dismukes@adacore.com>
19685 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
19686 inherited from an interface ancestor by another interface in the
19687 context of an instance as 'late'.
19688 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
19689 of a call to a function that dispatches on access result.
19690 (Check_Dispatching_Operation): In case of late overriding of a primitive
19691 that covers abstract interface subprograms we register it in all the
19692 secondary dispatch tables associated with abstract interfaces.
19693 (Check_Dispatching_Call): Add check that a dispatching call is not made
19694 to a function with a controlling result of a limited type. This is a
19695 current implementation restriction.
19696 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
19697 (Check_Dispatching_Operation): Do no emit a warning if the controlling
19698 argument is an interface type that is a generic formal.
19699 (Is_Interface_Subprogram): Removed.
19700 (Check_Dispatching_Operation): If the subprogram is not a dispatching
19701 operation, check the formals to handle the case in which it is
19702 associated with an abstract interface type.
19704 2006-10-31 Robert Dewar <dewar@adacore.com>
19705 Ed Schonberg <schonberg@adacore.com>

19714 * sem_eval.adb (Compile_Time_Compare): Make use of information from
19715 Current_Value in the conditional case, to evaluate additional
19716 comparisons at compile time.

19719 Hristian Kirtchev <kirtchev@adacore.com>
19720 Javier Miranda <miranda@adacore.com>
19722 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
19723 subprogram type to provide better diagnostics in case of ambiguity.
19724 (Covers): Handle coverage of formal and actual anonymous access types in
19725 the context of generic instantiation.
19726 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
19727 abstract interface types; this is required to handle concurrent types
19728 with discriminants and abstract interface types.
19729 (Covers): Include type coverage of both regular incomplete subtypes and
19730 incomplete subtypes of incomplete type visibles through a limited with

19742 Add missing continuation marks in error msgs
19743 (Unqualify): New function for removing zero or more levels of
19744 qualification from an expression. There are numerous places where this
19745 ought to be used, but we currently only deal properly with zero or one
19747 (In_Instance); The analysis of the actuals in the instantiation of a
19748 child unit is not within an instantiation, even though the parent
19749 instance is on the scope stack.
19750 (Safe_To_Capture_Value): Exclude the case of variables that are
19752 (Check_Obsolescent): Removed
19753 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
19754 is an aliased view, even when rewritten as a reference to the target
19755 object in an assignment.
19756 (Get_Subprogram_Entity): New function
19757 (Known_To_Be_Assigned): New function
19758 (Type_Access_Level): Compute properly the access level of a return

19765 has a null exclusion depending on its Nkind.
19766 Change Is_Lvalue to May_Be_Lvalue
19767 (May_Be_Lvalue): Extensive additional code to deal with subprogram
19768 arguments (IN parameters are not Lvalues, IN OUT parameters are).
19769 (Safe_To_Capture_Value): Extend functionality so it can be used for
19770 the current value condition case.
19771 (Has_Compatible_Alignment): New function
19772 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
19773 objects to handle the Ada 2005 case, where aliasedness no longer implies
19774 that the object is constrained. In particular, for dereferenced names,
19775 the designated object must be assumed to be unconstrained.
19776 (Kill_Current_Values): Properly deal with the case where we encounter
19777 a loop in the scope chain.
19778 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
19780 (Compile_Time_Constraint_Error): Improve error message in error case

19786 2006-10-31 Robert Dewar <dewar@adacore.com>
19788 * s-osinte-tru64.adb:
19789 Mark Asm statements Volatile to prevent warnings (seems a
19790 reasonable change anyway)
19793 * s-mastop-irix.adb: Add Volatile to Asm statements
19794 Suppresses warning, and seems appropriate in any case
19796 * s-osinte-vms.adb: Add Volatile to Asm statement

19810 Private_Extension_Declaration to the list of assertions.
19811 (Is_Entry_Barrier_Function): New flag
19812 (Has_Self_Reference): New flag on aggregates, to indicate that they
19813 contain a reference to the enclosing type, inserted through a default
19815 (Next_Rep_Item): Move from Node4 to Node5.
19816 (Entity): Add this field for N_Attribute_Definition_Clause.
19817 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
19818 (N_Return_Object_Declaration): Remove this node kind. We now use
19819 N_Object_Declaration instead.
19820 (Actual_Designated_Subtype): Move to a different place to make room in
19821 N_Extended_Return_Statement.
19822 (Procedure_To_Call): Move to a different place to make room in
19823 N_Extended_Return_Statement.
19824 (Return_Type): Removed this field to make room in return statements
19826 (Return_Statement_Entity): New field in return statements, in part to
19827 replace Return_Type, and in part to support the fact that return
19828 statements are now pushed on the scope stack during semantic analysis.
19829 (Return_Object_Declarations): New field to support extended return
19831 (N_Extended_Return_Statement): New node for extended_return_statement
19833 (N_Return_Object_Declaration): New node for part of
19834 extended_return_statement nonterminal. Needed because all the necessary
19835 fields won't fit in N_Extended_Return_Statement.
19836 Generic_associations now carry the Box_Present flag, to indicate a
19837 default for an actual in a partially parametrized formal package.
19839 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
19840 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
19841 and for the new predefined dispatching policies: EDF_Across_Priorities,

19843 Introduce new name Stub_Type for implementation defined attribute.
19844 Add pragma Preelaborable_Initialization
19845 Add entry for Priority attribute.

19854 * sprint.adb (Sprint_Node_Actual, case Parameter_Specification): Do not
19855 print null exclusion twice in the case of an access definition,
19856 Implement new -gnatL switch
19857 Remove N_Return_Object_Declaration. We now use
19858 N_Object_Declaration instead. Implement the case for
19859 N_Extended_Return_Statement. Alphabetize the cases.
19860 Add cases for new nodes N_Extended_Return_Statement and
19861 N_Return_Object_Declaration. The code is not yet written.
19862 Update the output for N_Formal_Object_Declaration
19863 and N_Object_Renaming_Declaration.
19864 (Write_Itype): Account for the case of a modular integer subtype whose

20435 Robert Dewar <dewar@adacore.com>
20437 * exp_ch4.adb (Expand_N_Allocator): If the allocated object is accessed
20438 through an access to class-wide interface we force the displacement of
20439 the pointer to the allocated object to reference the corresponding
20440 secondary dispatch table.
20441 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
20442 if Long_Shifts are supported on the target, even if 64 bit divides
20443 are not supported (configurable run time mode).
20444 (Expand_N_Type_Conversion): Do validity check if validity checks on
20445 operands are enabled.
20446 (Expand_N_Qualified_Expression): Do validity check if validity checks
20447 on operands are enabled.

20458 the bounds of the type of the discriminant are not static expressions.
20460 * sem_aggr.adb (Check_Static_Discriminated_Subtype): Return false if
20461 the bounds of the discriminant type are not static.
20463 2006-02-17 Robert Dewar <dewar@adacore.com>
20465 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
20466 then we close To if it is valid.

20476 * Makefile.in: Use VMS64 specialized versions of several units in
20477 Interfaces.C hierarchy to be compatible with HP C default size choices.
20478 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
20480 2006-02-17 Ed Schonberg <schonberg@adacore.com>
20482 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
20483 instantiation, the corresponding entity is the related_instance of the

20492 Ed Schonberg <schonberg@adacore.com>
20494 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
20495 type we cannot inherit the primitive operations; we inherit the
20496 Corresponding_Record_Type (which has the list of primitive operations).
20497 (Check_Anonymous_Access_Types): When creating anonymous access types for
20498 access components, use Rewrite in order to preserve the tree structure,
20500 (Analyze_Object_Declaration): For limited types with access
20501 discriminants with defaults initialized by an aggregate, obtain
20502 subtype from aggregate as for other mutable types.
20503 (Derived_Type_Declaration): If the derived type is a limited interface,
20504 set the corresponding flag (Is_Limited_Record is not sufficient).

20513 2006-02-17 Javier Miranda <miranda@adacore.com>
20515 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
20516 abstract interface type, the static analysis is not enough to know if
20517 the interface is implemented or not by the source tagged type. Hence
20518 we must pass the work to the expander to generate the required code to
20519 evaluate the conversion at run-time.
20520 (Resolve_Equality_Op): Do not apply previous
20521 transformation if expansion is disasbled, to prevent anomalies when
20522 locating global references in a generic unit.

20702 table to take advantage of the 16 priority levels available on Windows
20703 2000 and XP. On NT4 there are only 7 priority levels, this is properly
20704 supported by this new mapping.

20750 (Read): Change the implementation to support unicode characters. It is
20751 not possible to use strlen() on Windows as this version supports only
20752 standard ASCII characters. So the length of the directory entry is now
20753 returned from the imported __gnat_readdir routine.

20791 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
20792 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
20793 necessary since these are not different types and pointers may
20794 actually designate any subtype in this hierarchy.
20795 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
20796 discriminants but put them into record only if not Unchecked_Union;
20797 pass flag to components_to_record showing Unchecked_Union.
20798 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
20799 components before variants; don't set TYPE_UNCHECKED_UNION_P.
20800 (components_to_record): New argument UNCHECKED_UNION.
20801 Remove special case code for Unchecked_Union and instead use main code
20802 with small changes.
20805 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
20806 variable with the expression being built, only its inner field.

20809 emit_sequence_entry_statements.
20810 (emit_sequence_entry_statements, body_with_handlers_p): Delete.

20815 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
20816 substituted for a CONST_DECL.
20817 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
20818 Etype to assoc_to_constructor.
20819 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
20820 discriminants of Unchecked_Union.
20821 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
20822 don't need cluttering preprocessor directives.
20823 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
20824 condition handler as current in the compiled function.
20825 (body_with_handlers_p): New function. Tell whether a given sequence of
20826 statements node is attached to a package or subprogram body and involves
20827 exception handlers possibly nested within inner block statements.
20828 (emit_sequence_entry_statements): New function, to emit special
20829 statements on entry of sequences when necessary. Establish GNAT
20830 condition handler in the proper cases for VMS.
20831 (Handled_Sequence_Of_Statements_to_gnu): Start block code with
20832 emit_sequence_entry_statements.
20834 * utils2.c (find_common_type): If both input types are BLKmode and

21325 functionality of Set_Prim_Op_Address but applied to predefined primitive
21327 (Set_Signature): New subprogram used to store the signature of a DT.
21328 (Displace): If the Offset_To_Top value is not static then call the
21329 function generated by the expander to get such value; otherwise use
21330 the value stored in the table of interfaces.
21331 (Offset_To_Top): The type of the actual has been changed to Address to
21332 give the correct support to tagged types with discriminants. In this
21333 case this value is stored just immediately after the tag field.
21334 (Set_Offset_To_Top): Two new formals have been added to indicate if the
21335 offset_to_top value is static and hence pass this value to the run-time
21336 to store it in the table of interfaces, or else if this value is dynamic
21337 and then pass to the run-time the address of a function that is
21338 generated by the expander to provide this value for each object of the
21341 * rtsfind.ads (Default_Prin_Op_Count): Removed.
21342 (Default_Prim_Op_Count): New entity
21343 (Get_Predefined_Prim_Op_Address): New entity
21344 (Set_Predefined_Prim_Op_Address): New entity
21345 (RE_Set_Signature): New entity

21348 Ed Schonberg <schonberg@adacore.com>
21350 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
21351 Make_Adjust_Call done for a newly-allocated object.
21353 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
21354 in a subprogram are wrapped in a cleanup block, indicate that the
21355 subprogram contains an inner block with an exception handler.
21356 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
21357 Adjust call is for a newly-allocated object. In that case we must not
21358 assume that the finalization list chain pointers are correct (since they
21359 come from a bit-for-bit copy of the original object's pointers) so if
21360 the attach level would otherwise be zero (no change), we set it to 4
21361 instead to cause the pointers to be reset to null.
21363 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
21364 reset chain pointers to null.
21366 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21368 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
21369 string, and the context requires a loop for the assignment (e.g.
21370 because the left-hand side is packed), generate a unique name for the
21371 temporary that holds the string, to prevent spurious name clashes.
21373 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21374 Javier Miranda <miranda@adacore.com>
21375 Robert Dewar <dewar@adacore.com>
21376 Gary Dismukes <dismukes@adacore.com>
21378 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
21379 return unconstrained arrays.
21381 (Expand_Call): An indirect call through an access parameter of a
21382 protected operation is not a protected call.
21383 Add circuit to raise CE in Ada 2005 mode following call
21384 to Raise_Exception.
21385 (Register_DT_Entry): Do nothing if
21386 the run-time does not give support to abstract interfaces.
21387 (Freeze_Subprogram): In case of dispatching operations, do not generate
21388 code to register the operation in the dispatch table if the source
21389 is compiled with No_Dispatching_Calls.
21390 (Register_Predefined_DT_Entry): Generate code that calls the new
21391 run-time subprogram Set_Predefined_Prim_Op_Address instead of
21392 Set_Prim_Op_Address.
21394 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
21395 on array assignments if the right-hand side is a function call that has
21396 been inlined. Check is performed on the assignment in the block.
21397 (Process_Bounds): If bounds and range are overloaded, apply preference
21398 rule for root operations to disambiguate, and diagnose true ambiguity.
21399 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
21400 a tag-indeterminate right-hand side even when Expander_Active is True.
21401 Needed to ensure that dispatching calls to T'Input are allowed and
21402 get the tag of the target class-wide object.
21404 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
21405 an inherited primitive operation that already overrides several
21406 abstract interface primitives. For transitivity, the new entity must
21407 also override all the abstract interface primitives covered by the
21408 inherited overriden primitive.
21409 Emit warning if new entity differs from homograph in same scope only in
21410 that one has an access parameter and the other one has a parameter of
21411 a general access type with the same designated type, at the same
21412 position in the signature.
21413 (Make_Inequality_Operator): Use source locations of parameters and
21414 subtype marks from corresponding equality operator when creating the
21415 tree structure for the implicit declaration of "/=". This does not
21416 change anything in behaviour except that the decoration of the
21417 components of the subtree created for "/=" allows ASIS to get the
21418 string images of the corresponding identifiers.
21419 (Analyze_Return_Statement): Remove '!' in warning message.
21420 (Check_Statement_Sequence): Likewise.
21421 (Analyze_Subprogram_Body): For an access parameter whose designated type
21422 is an incomplete type imported through a limited_with clause, use the
21423 type of the corresponding formal in the body.
21424 (Check_Returns): Implicit return in No_Return procedure now raises
21425 Program_Error with a compile time warning, instead of beging illegal.
21426 (Has_Single_Return): Function returning unconstrained type cannot be
21427 inlined if expression in unique return statement is not an identifier.
21428 (Build_Body_To_Inline): It is possible to inline a function call that
21429 returns an unconstrained type if all return statements in the function
21430 return the same local variable. Subsidiary procedure Has_Single_Return
21431 verifies that the body conforms to this restriction.
21433 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
21434 same type, and one of them is of an anonymous access type, convert
21435 the other operand to it, so that this is a valid binary operation for
21437 (Resolve_Type_Conversion): Handle subtypes of protected types and
21438 task types when accessing to the corresponding record type.
21439 (Resolve_Allocator): Add '\' in 2-line warning message.
21440 Remove '!' in warning message.
21441 (Resolve_Call): Add '\' in 2-line warning message.
21442 (Valid_Conversion): Likewise.
21443 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
21444 resulting type may be an access type with an implicit dereference.
21445 Obtain the proper component from the designated type.
21446 (Make_Call_Into_Operator): Handle properly a call to predefined equality
21447 given by an expanded name with prefix Standard, when the operands are
21448 of an anonymous access type.
21449 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
21450 Explicit_Dereference and Resolve_Selected_Component, to verify that the
21451 prefix of the expression is not of an incomplete type. Allows full
21452 diagnoses of all semantic errors.
21453 (Resolve_Actuals): If the actual is an allocator whose directly
21454 designated type is a class-wide interface we build an anonymous
21455 access type to use it as the type of the allocator. Later, when
21456 the subprogram call is expanded, if the interface has a secondary
21457 dispatch table the expander will add a type conversion to force
21458 the displacement of the pointer.
21459 (Resolve_Call): If a function that returns an unconstrained type is
21460 marked Inlined_Always and inlined, the call will be inlined and does
21461 not require the creation of a transient scope.
21462 (Check_Direct_Boolean_Op): Removed
21463 (Resolve_Comparison_Op): Remove call to above
21464 (Resolve_Equality_Op): Remove call to above
21465 (Resolve_Logical_Op): Inline above, since this is only call.
21466 (Valid_Conversion): Handle properly conversions between arrays of
21467 convertible anonymous access types.
21470 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
21471 the literal in an unchecked conversion, because GCC 4.x needs a static
21472 value for a string bound.
21474 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21475 Hristian Kirtchev <kirtchev@adacore.com>
21477 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
21478 components of the corresponding record, take into account component
21479 definitions that are access definitions.
21480 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
21481 procedure is not considered a dispatching call and will be expanded
21484 2006-02-13 Javier Miranda <miranda@adacore.com>
21486 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
21487 controlling argument of the dispatching call is an abstract interface
21488 class-wide type then we use it directly.
21489 Check No_Dispatching_Calls restriction.
21490 (Default_Prim_Op_Position): Remove the code that looks for the last
21491 entity in the list of aliased subprograms. This code was wrong in
21493 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
21494 when the source is compiled with the No_Dispatching_Calls restriction.
21495 (Init_Predefined_Interface_Primitives): No need to inherit primitives
21496 if we are compiling with restriction No_Dispatching_Calls.
21497 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
21498 subprograms if we are compiling under No_Dispatching_Calls restriction.
21499 (Make_DT): Generate a dispatch table with a single dummy entry if
21500 we are compiling with the No_Dispatching_Calls restriction. In
21501 addition, in this case we don't generate code that calls to the
21502 following run-time subprograms: Set_Type_Kind, Inherit_DT.
21503 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
21504 of this subprogram if compiling with the No_Dispatching_Calls
21506 (Expand_Type_Conversion): Instead of using the actual parameter,
21507 the argument passed as parameter to the conversion function was
21508 erroneously referenced by the expander.
21509 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
21510 Set_Predefined_Primitive_Op_Address and Set_Signature.
21511 (Expand_Dispatching_Call): Generate call to
21512 Get_Predefined_Prim_Op_Address for predefined primitives.
21513 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
21514 predefined primitives.
21515 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
21516 primitives we reserve one dummy entry to ensure that the tag does not
21517 point to some memory that is associated with some other object. In
21518 addition, remove all the old code that generated the assignments
21519 associated with the signature of the dispatch table and replace them
21520 by a call to the new subprogram Set_Signature.
21521 (Set_All_DT_Position): Change the algorithm because now we have a
21522 separate dispatch table associated with predefined primitive operations.
21523 (Expand_Interface_Conversion): In case of non-static offset_to_top
21524 add explicit dereference to get access to the object after the call
21525 to displace the pointer to the object.
21526 (Expand_Interface_Thunk): Modify the generation of the actual used
21527 in the calls to the run-time function Offset_To_Top to fulfil its
21529 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
21531 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21533 * exp_dist.adb (Copy_Specification): For access parameters, copy
21534 Null_Exclusion flag, which will have been set for stream subprograms
21537 2006-02-13 Pascal Obry <obry@adacore.com>
21539 * expect.c (__gnat_expect_portable_execvp): New implementation. The
21540 previous implementation was using the C runtime spawnve routine but
21541 the corresponding wait was using directly the Win32 API. This was
21542 causing some times a lock when waiting for an event using
21543 WaitForSingleObject in __gnat_waitpid. This new implementation uses
21544 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
21545 API fixes this problem.
21547 2006-02-13 Robert Dewar <dewar@adacore.com>
21549 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

21557 array reference that is an explicit dereference, mark the converted
21558 (packed) array reference as analyzed to prevent a forthcoming
21559 reanalysis from resetting its type to the original (non-packed) array

21563 Javier Miranda <miranda@adacore.com>
21564 Eric Botcazou <ebotcazou@adacore.com>
21566 * exp_util.ads, exp_util.adb (Find_Prim_Op,
21567 Is_Predefined_Primitive_Operation): When
21568 searching for the predefined equality operator, verify that operands
21569 have the same type.
21570 (Is_Predefined_Dispatching_Operation): Remove the code that looks
21571 for the last entity in the list of aliased subprograms. This code
21572 was wrong in case of renamings.
21573 (Set_Renamed_Subprogram): New procedure
21574 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
21575 Exp_Type constant computed when entering this subprogram.

21577 (OK_To_Do_Constant_Replacement): New function
21578 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
21579 (Side_Effect_Free): An attribute reference 'Input is not free of
21580 side effect, unlike other attributes that are functions. (from code
21582 (Remove_Side_Effects): Expressions that involve packed arrays or records
21583 are copied at the point of reference, and therefore must be marked as
21584 renamings of objects.
21585 (Is_Predefined_Dispatching_Operation): Return false if the operation is
21586 not a dispatching operation.
21589 (Remove_Side_Effects): Lift enclosing type conversion nodes for
21590 elementary types in all cases.
21592 2006-02-13 Javier Miranda <miranda@adacore.com>

21595 task types when accessing to the corresponding record type.
21596 Remove '!' in warning message.
21598 2006-02-13 Olivier Hainque <hainque@adacore.com>
21600 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
21601 to avoid useless and space inefficient overalignments on targets where
21602 Max_Alignment is larger than 16.
21604 2006-02-13 Pascal Obry <obry@adacore.com>
21606 * g-catiio.adb (Sec_Number): New type used to compute the number of
21607 seconds since 1-1-1970.
21608 (Image) [Natural]: The parameter was an Integer, as we can't deal with
21609 negative numbers (years, months...) it is better to have a Natural here.
21611 (Image) [Number]: Change parameter from Long_Integer to Number.
21612 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
21613 overflow for dates past year 2038.
21615 2006-02-13 Matthew Heaney <heaney@adacore.com>
21617 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
21620 2006-02-13 Arnaud Charlet <charlet@adacore.com>
21622 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
21624 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
21625 finalization can occur normally.
21627 2006-02-13 Vincent Celier <celier@adacore.com>
21629 * gnatcmd.adb (Rules_Switches): New table
21630 (Add_To_Rules_Switches): New procedure
21631 (GNATCmd): For command CHECK, put all options following "-rules" in the
21632 Rules_Switches table. Append these -rules switches after the -cargs
21635 2006-02-13 Robert Dewar <dewar@adacore.com>
21637 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
21638 These two cases were generating incorrect output, and if this unit
21639 was built with checks on, generated a discriminant mismatch constraint
21642 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21643 Robert Dewar <dewar@adacore.com>
21645 * lib-xref.adb (Get_Type_Reference): For a private type whose full
21646 view is an array type, indicate the component type as well, for
21647 navigation purposes.

21649 of violating pragma Unreferenced.
21650 Do not give Ada 2005 warning except on real reference.

21654 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
21655 main source, add switch -mdebug-main=_ada_ so that the executable can
21656 be debugged by the standard VMS debugger.
21657 (Gnatmake): Set No_Main_Subprogram to True when there is no main
21658 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
21659 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
21660 of the last source, as the binding and linking phases are never
21662 Set all executable obsolete when rebuilding a library.
21664 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
21667 2006-02-13 Javier Miranda <miranda@adacore.com>
21670 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
21671 code to improve the error message reported when the program has
21672 declarations of abstract interface types and it is not compiled with
21673 the -gnat05 switch.
21674 (P_Access_Definition): Reorganize the code to improve the error
21675 message reported when the new Ada 2005 syntax for anonymous
21676 access types is used and the program is not compiled with the

21716 Prj.Nmsc.Check with parameter When_No_Sources.
21717 (Process): New parameter When_No_Sources. Call Check with parameter

21729 When removing nodes (attributes Source_Dirs, Source_Files,
21730 Source_List_File and package Naming), save the comments and attach the
21731 saved comments to the newly created nodes.
21732 Do not add a with clause for the naming package if one already exists.

21748 No_Return procedure with procedure that is not No_Return
21749 (Check_Dispatching_Call): Suppress the check for an abstract operation
21750 when the original node of an actual is a tag-indeterminate attribute
21751 call, since the attribute, which must be 'Input, can never be abstract.
21752 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
21753 call to the Input attribute (even when rewritten).
21754 (Propagate_Tag): Augment comment to indicate the possibility of a call
21755 to an Input attribute.
21757 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
21758 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
21760 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
21761 No_Wide_Characters is no longer partition-wide

21771 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
21772 handles default-initialized components to keep separate the management
21773 of this feature but also avoid the unrequired resolution and
21774 expansion of components that do not have partially initialized
21776 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
21777 (Check_Bounds): Likewise.
21778 (Check_Length): Likewise.
21780 2006-02-13 Javier Miranda <miranda@adacore.com>
21781 Ed Schonberg <schonberg@adacore.com>
21783 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21784 abstract interface type call analyze_and_resolve to expand the type
21785 conversion into the corresponding displacement of the
21786 reference to the base of the object.
21787 (Eval_Attribute, case Width): For systems where IEEE extended precision
21788 is supported, the maximum exponent occupies 4 decimal digits.
21789 (Accessibility_Message): Add '\' in 2-line warning message.
21790 (Resolve_Attribute): Likewise.
21791 (case Attribute_Access): Significantly revise checks
21792 for illegal access-to-subprogram Access attributes to properly enforce
21793 the rules of 3.10.2(32/2).
21794 Diagnose use of current instance with an illegal attribute.
21796 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21798 (Enclosing_Generic_Unit): New function to return a node's innermost
21799 enclosing generic declaration node.
21800 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21801 (Type_Access_Level): The accessibility level of anonymous acccess types
21802 associated with discriminants is that of the current instance of the
21803 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21804 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21805 (Kill_Current_Values_For_Entity): New function
21806 (Enter_Name): Change formal type to Entity_Id
21808 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21809 Ed Schonberg <schonberg@adacore.com>
21810 Gary Dismukes <dismukes@adacore.com>
21812 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21813 Analyze_Compilation_Unit.
21814 Detect and warn on redundant with clauses detected in a package spec
21815 and/or body when -gnatwr is used.
21816 (Analyze_Context): Analyze config pragmas before other items
21817 (Install_Context_Items): Don't analyze config pragmas here
21818 (Install_Limited_Withed_Unit): Set limited entity of package in
21819 with_clause so that cross-reference information or warning messages on
21820 unused packages can be properly generated
21821 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21822 has Error_Posted set. Prevent infinite loops in illegal programs.
21823 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21824 to the point of the error test requiring the current unit to be private.
21825 This ensures that private with clauses are not exempted from the basic
21826 checking for being a descendant of the same library unit parent as a
21827 withed private descendant unit.
21828 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21829 handle private with clauses properly, as well as to account for cases
21830 where the withed unit is a public descendant of a private ancestor
21831 (in which case the current unit must be a descendant of the private
21832 ancestor's parent). The spec comments were updated accordingly. Also,
21833 the old error message in this subprogram was replaced with error
21834 messages that mirror the errors tested and reported by
21835 Check_Private_Child_Unit.
21836 Parameter and variable names improved for readability.
21837 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21838 private as the precondition for calling
21839 Check_Private_Limited_Withed_Unit since that subprogram has been
21840 revised to test public units as well as private units.

21843 Robert Dewar <dewar@adacore.com>
21844 Ed Schonberg <schonberg@adacore.com>
21845 Javier Miranda <miranda@adacore.com>
21847 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21848 that Scope_Stack.First = 1.
21849 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21850 were not always properly handled previously.
21851 (Formal_Entity): Complete rewrite, to handle properly some complex case
21852 with multiple levels of parametrization by formal packages.
21853 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21854 to the corresponding derived type declaration for proper semantics.
21856 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21857 (Check_Component): Enforce restriction on components of
21858 unchecked_unions: a component in a variant cannot contain tasks or
21860 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21862 Add pragma Ada_2005 (synonym for Ada_05)
21863 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21864 were not always properly handled previously.
21865 Document that pragma Propagate_Exceptions has no effect
21866 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21867 (Set_Convention_From_Pragma): Check that if a convention is
21868 specified for a dispatching operation, then it must be
21869 consistent with the existing convention for the operation.
21870 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21871 longer required to specify an vtable-ptr component in the record. For
21872 compatibility reasons we leave the support for the previous definition.
21873 (Analyze_Pragma, case No_Return): Allow multiple arguments
21875 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21876 non-overrideen inherited operation with a controlling result as
21877 illegal only its implicit declaration comes from the derived type
21878 declaration of its result's type.
21879 (Check_Possible_Deferred_Completion): Relocate the object definition
21880 node of the subtype indication of a deferred constant completion rather
21881 than directly analyzing it. The analysis of the generated subtype will
21882 correctly decorate the GNAT tree.
21883 (Record_Type_Declaration): Check whether this is a declaration for a
21884 limited derived record before analyzing components.
21885 (Analyze_Component_Declaration): Diagnose record types not explicitly
21886 declared limited when a component has a limited type.
21887 (Build_Derived_Record_Type): Code reorganization to check if some of
21888 the inherited subprograms of a tagged type cover interface primitives.
21889 This check was missing in case of a full-type associated with a private
21891 (Constant_Redeclaration): Check that the subtypes of the partial and the
21892 full view of a constrained deferred constant statically match.
21893 (Mentions_T): A reference to the current type in an anonymous access
21894 component declaration must be an entity name.
21895 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21896 class_wide type to refer to full type, not to the incomplete one.
21897 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21898 available. Required to give support to the certified run-time.
21899 (Analyze_Component_Declaration): In case of anonymous access components
21900 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21901 (Process_Discriminants): For an access discriminant, use the
21902 discriminant specification as the associated_node_for_itype, to
21903 simplify accessibility checks.
21905 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21906 Javier Miranda <miranda@adacore.com>
21908 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21909 abstract interpretations on an operator, remove interpretations that
21910 yield Address or a type derived from it, if one of the operands is an
21912 (Try_Object_Operation.Try_Primitive_Operation,
21913 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21914 location when creating the new reference to a primitive or class-wide
21915 operation as a part of rewriting a subprogram call.
21916 (Try_Primitive_Operations): If context requires a function, collect all
21917 interpretations after the first match, because there may be primitive
21918 operations of the same type with the same profile and different return
21919 types. From code reading.
21920 (Try_Primitive_Operation): Use the node kind to choose the proper
21921 operation when a function and a procedure have the same parameter
21923 (Complete_Object_Operation): If formal is an access parameter and prefix
21924 is an object, rewrite as an Access reference, to match signature of
21925 primitive operation.
21926 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21927 by an expanded name with prefix Standard, when the operands are of an
21928 anonymous access type.
21929 (Remove_Abstract_Operations): If the operation is abstract because it is
21930 inherited by a user-defined type derived from Address, remove it as
21931 well from the set of candidate interpretations of an overloaded node.
21932 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21935 2006-02-13 Bob Duff <duff@adacore.com>
21937 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21938 redundant use clauses.
21939 In particular, if the scope of two use clauses overlaps, but one is not
21940 entirely included in the other, we should not warn. This can happen
21941 with nested packages.
21942 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21943 reported errors. The bug was reported when the compiler was built
21944 with assertions enabled.
21945 (Find_Type): If the node is a 'Class reference and the prefix is a
21946 synchronized type without a corresponding record, return the type
21949 2006-02-13 Javier Miranda <miranda@adacore.com>
21951 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21952 if this is the full-declaration associated with a private declaration
21953 that implement interfaces, then the private type declaration must be
21955 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21956 as aliased. The use of the 'access attribute is not available for such
21957 object (for this purpose the object should be explicitly marked as
21958 aliased, but being an anonymous type this is not possible).
21960 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21961 Robert Dewar <dewar@adacore.com>
21963 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21964 compilation unit is an elaboration scope.
21965 (Add_Task_Proc): Add '\' in 2-line warning message.
21966 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21968 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21969 Javier Miranda <miranda@adacore.com>
21971 * sem_type.adb (Write_Overloads): Improve display of candidate
21973 (Add_One_Interp): Do not add to the list of interpretations aliased
21974 entities corresponding with an abstract interface type that is an
21975 immediate ancestor of a tagged type; otherwise we have a dummy
21976 conflict between this entity and the aliased entity.
21977 (Disambiguate): The predefined equality on universal_access is not
21978 usable if there is a user-defined equality with the proper signature,
21979 declared in the same declarative part as the designated type.
21980 (Find_Unique_Type): The universal_access equality operator defined under
21981 AI-230 does not cover pool specific access types.
21982 (Covers): If one of the types is a generic actual subtype, check whether
21983 it matches the partial view of the other type.
21985 2006-02-13 Thomas Quinot <quinot@adacore.com>
21987 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21988 line. This is necessary to allow In_Extended_Main_Unit to provide
21989 correct results for itypes while writing out expanded source.
21990 (Close_File): No need to update the source_index_table here since it's
21991 now done for each line.
21993 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21994 Robert Dewar <dewar@adacore.com>
21996 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21997 preserve the source unit where the itype is declared, and prevent a
21999 (Note_Implicit_Run_Time_Call): New procedure
22000 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
22003 * sprint.ads: Document use of $ for implicit run time routine call
22005 2006-02-13 Quentin Ochem <ochem@adacore.com>
22007 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
22010 2006-02-13 Bob Duff <duff@adacore.com>
22012 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
22013 Scan_Unsigned, so we do not scan leading blanks and sign twice.
22014 Integer'Value("- 5") and Integer'Value("-+5") now correctly
22015 raise Constraint_Error.
22017 * s-vallli.adb (Scan_Long_Long_Integer): Call
22018 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
22019 do not scan leading blanks and sign twice.
22020 Integer'Value("- 5") and Integer'Value("-+5") now correctly
22021 raise Constraint_Error.
22023 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
22024 Scan_Long_Long_Unsigned): Split out most of the processing from
22025 Scan_Long_Long_Unsigned out into
22026 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
22027 This prevents scanning leading blanks and sign twice.
22028 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
22031 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
22032 out most of the processing from Scan_Unsigned out into
22033 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
22034 This prevents scanning leading blanks and sign twice.
22036 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
22037 use with Modular'Value attribute.
22038 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
22041 2006-02-13 Robert Dewar <dewar@adacore.com>
22043 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
22045 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
22047 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
22048 (PPC VxWorks): Likewise.
22049 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.

22167 Ada bind file prefix on VMS from b$ to b__.
22169 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
22170 --GCC so that Get_Target_Parameters can find system.ads.
22171 (Gnatlink): Call Get_Target_Parameters in mainline.
22172 Initialize standard packages for Targparm.
22173 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

22210 (Target_Object_Suffix): Initialize with target object suffix.
22212 * rident.ads: Add special exception to license.
22214 * targparm.adb (Get_Target_Parameters): Set the value of
22215 Multi_Unit_Index_Character after OpenVMS_On_Target gets its definitive
22217 (Get_Target_Parameters): Set OpenVMS_On_Target if openvms.

22236 * a-taster.ads, a-taster.adb: New files.
22238 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
22239 link to the version that does nothing. This way the task termination
22240 routine is not executed twice for the environment task when finishing
22241 because of an unhandled exception.
22243 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
22244 handler because of an unhandled exception.
22246 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
22247 System.Tasking.Utilities instead of that in System.Tasking.Stages.

22252 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
22253 non-tasking version of the soft link for task termination. We do
22254 nothing since if we are using the non-tasking version it
22255 means that the task termination functionality is not used.
22256 (Null_Finalize_Global_List): Add this null version for the procedure
22257 in charge of finalizing the global list for controlled objects.
22258 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
22259 instead for handling run-time termination in a more flexible way.
22260 (Adafinal_NT): This new procedure will take care of finalizing the
22261 global list for controlled objects if needed, but no tasking
22264 * s-tarest.adb (Task_Lock): Do not try to lock again the
22265 Global_Task_Lock if we already own it. Otherwise, we get blocked in
22266 some run-time operations.
22267 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
22268 until all nested locks have been released.
22269 (Task_Wrapper): Call the fall-back task termination handler. It
22270 applies to all tasks but the environment task.
22271 (Finalize_Global_Tasks): Add the call for the task termination
22272 procedure for the environment task.

22289 Ada.Task_Termination, for avoiding circular dependencies.
22290 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
22291 for storing task termination handlers. In addition,
22292 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to

22309 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
22310 potentially blocking operations has been moved from
22311 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
22312 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass

22389 have to use the Offset_To_Top run-time function to get this information;
22390 otherwise if the pointer to the base of the object has been displace
22391 we get a wrong value if we use the 'position attribute.
22393 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
22394 all the calls to Expand_Interface_Thunk.

22431 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
22432 Init_Secondary_Tags_Internal to allow its use with interface types and
22433 also to generate the code for the new additional actual required
22434 by Set_Offset_To_Top.
22435 (Build_Init_Statements): In case of components associated with abstract
22436 interface types there is no need to generate a call to its IP.

22448 properly protected objects and attach handler in the case of the
22449 restricted profile.

22463 pointer initialization values. Make a SAVE_EXPR instead. Add comments
22464 about the use and expansion of SAVE_EXPRs in the various possible
22465 renaming handling cases.
22466 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
22467 abusing DECL_FCONTEXT.

22637 are implemented by the ancestors.
22638 (Derived_Type_Declaration): If the parent of the full-view is an
22639 interface perform a transformation of the tree to ensure that it has
22640 the same parent than the partial-view. This simplifies the job of the

22642 needed because the list of interfaces of the full-view can be given in
22644 (Process_Full_View): The parent of the full-view does not need to be
22645 a descendant of the parent of the partial view if both parents are
22647 (Analyze_Private_Extension_Declaration): If declaration has an explicit
22648 "limited" the parent must be a limited type.

22725 attributes are visible at the point of the subprogram declaration.
22726 For Ada 2005, the error message is modified to indicate that the

22759 types use the corresponding record type. This was not needed before
22760 the implementation of Ada 2005 synchronized types because
22761 concurrent types were never tagged types in Ada 95.
22763 2005-12-09 Ed Schonberg <schonberg@adacore.com>

22889 * socket.c: Add extern int h_errno for rtems since networking header
22890 files are not available at this point in a tool bootstrap. Newlib
22891 only has basic C library header files.

22894 Roger Sayle <roger@eyesopen.com>
22897 * misc.c (internal_error_function): Don't use vsprintf to format

22984 * gen-soccon.c: Complete value expansion should not be performed on
22985 TARGET, as it has the form of a math expression, and some components
22986 may be platform-defined macros.
22987 For VxWorks, generate the OK and ERROR values.
22988 New constants giving the sizes of the components of C struct timeval.

23000 deal with different cases of static and dynamic elaboration checks (all
23001 checks does not count in the first case, but does in the second).

23007 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
23008 elementary types using the operator in standard. It is cleaner not to
23009 modify the programmers intent, especially in the case of floating-point.
23010 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
23011 it did not matter because we always rewrote a/=b to not(a=b).
23012 (Expand_Allocator_Expression): For an allocator expression whose nominal
23013 subtype is an unconstrained packed type, convert the expression to its
23014 actual constrained subtype.
23015 Implement warning for <= or >= where < or > not possible
23016 Fix to Vax_Float tests (too early in many routines, causing premature
23017 Vax_Float expansions.
23019 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
23020 to be used with packages and generic packages as well as with

23023 of pragma Suppress (All_Checks)
23024 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
23025 a string literal for precise control over warnings.

23035 Allow optional = after -gnatm
23036 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
23037 longer sets Elaboration_Checks.
23038 Code to set warning mode moved to Sem_Warn
23039 so that it can be shared by pragma processing.
23041 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
23044 * s-taprop-solaris.adb:
23045 Change some <= to =, to avoid new warning

23051 2005-11-14 Robert Dewar <dewar@adacore.com>
23053 * exp_vfpt.adb: Handle /= case
23054 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
23055 so that we do not get duplicate scaling for fixed point conversions.
23057 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
23059 2005-11-14 Matthew Gingell <gingell@adacore.com>
23061 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
23062 Increase default priority on Lynx from 15 to 17, and meet the Ada
23063 requirement that Default_Priority be ((Priority'First +
23064 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

23166 we are not defining the type.
23167 <E_Record_Type>: Likewise.
23168 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
23169 to get advantage of the new maybe_stabilize_reference interface, to
23170 ensure that what we reference is indeed stabilized instead of relying
23171 on assumptions on what the stabilizer does.
23172 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
23173 type imported through a limited_with clause, use its non-limited view.
23174 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
23176 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
23177 of #if sections + explicit comparisons of convention identifiers.
23178 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
23179 before early-returning for certain types when code generation is
23181 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
23182 nullification of gnu_expr we do for objects with address clause and
23183 that we are not defining.
23184 (elaborate_expression_1): Do not create constants when creating
23185 variables needed by the debug info: the dwarf2 writer considers that
23186 CONST_DECLs is used only to represent enumeration constants, and emits
23188 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
23189 object with an address clause into an indirect reference, drop the
23190 initializing expression.
23192 (STACK_CHECK_BUILTIN): Delete.
23193 (STACK_CHECK_PROBE_INTERVAL): Likewise.

23201 if there is an actual subtype provided by the front-end, use that
23202 subtype to build an actual type with bounds template.
23203 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
23204 is provided by the front-end, use that subtype to compute the size of
23205 the deallocated object.
23206 (gnat_to_gnu): When adding a statement into an elaboration procedure,
23207 check for a potential violation of a No_Elaboration_Code restriction.
23208 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
23209 with extra arguments to control whether to recurse through non-values
23210 and to let the caller know if the stabilization has succeeded.

23212 maybe_stabilize, for common uses without restriction on lvalues and
23213 without need to check for the success indication.
23214 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
23215 pass false instead of 0 as the FORCE argument which is a bool.
23216 (Identifier_to_gnu): Remove checks ensuring that an renamed object
23217 attached to a renaming pointer has been properly stabilized, as no such
23218 object is attached otherwise.
23219 (call_to_gnu): Invoke create_var_decl to create the temporary when the
23220 function uses the "target pointer" return mechanism.
23221 Reinstate conversion of the actual to the type of the formal
23222 parameter before any other specific treatment based on the passing
23223 mechanism. This turns out to be necessary in order for PLACEHOLDER
23224 substitution to work properly when the latter type is unconstrained.
23226 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
23228 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
23229 with extra arguments to control whether to recurse through non-values
23230 and to let the caller know if the stabilization has succeeded.
23232 * utils2.c (gnat_build_constructor): Only sort the fields for possible
23233 static output of record constructor if all the components are constant.
23234 (gnat_build_constructor): For a record type, sort the list of field
23235 initializers in increasing bit position order.
23236 Factor common code to build a storage type for an unconstrained object
23237 from a fat or thin pointer type and a constrained object type.
23238 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
23239 types variants, and process special cases of VIEW_CONVERT expressions
23240 as their NOP_EXPR counterpart to ensure we get to the
23241 CORRESPONDING_VARs associated with CONST_DECls.
23242 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs

23444 Use Universal_Real instead of Long_Long_Float when we need a high
23445 precision float type for the generated code (prevents gratuitous
23446 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23447 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
23448 'Terminated for task interface class-wide objects. Generate a call to
23449 the predefined dispatching routine used to retrieve the _task_id from

23478 (Expand_N_Return_Statement): When returning a mutable record, convert
23479 the return value into its actual subtype in order to help the backend

23510 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

23530 attribute of the N_Free_Statement.
23531 Generate itype for classwide designated object in both cases of

23722 * sem_ch10.adb: Change name Is_Package to Is_Package_Or_Generic_Package
23723 Do not give obsolescent warning on with of subprogram (since we
23725 (Analyze_With_Clause): Add test for obsolescent package
23726 (Install_Context_Clauses): If the unit is the body of a child unit, do
23727 not install twice the private declarations of the parents, to prevent
23728 circular lists of Use_Clauses in a parent.
23729 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
23730 compiling body of child unit.
23731 Use new class N_Subprogram_Instantiation
23732 (Expand_With_Clause): If this is a private with_clause for a child unit,
23733 appearing in the context of a package declaration, then the implicit
23734 with_clauses generated for parent units are private as well.
23735 (License_Check): Do not generate message if with'ed unit is internal

23739 Thomas Quinot <quinot@adacore.com>
23741 * sem_ch12.ads, sem_ch12.adb (Map_Entities): Exclude entities whose
23742 names are internal, because they will not have a corresponding partner
23743 in the actual package.
23744 (Analyze_Formal_Package): Move the setting of the formal package spec's
23745 Generic_Parent field so that it occurs prior to analyzing the package,
23746 to allow proper operation of Install_Parent_Private_Declarations.
23747 (Analyze_Package_Instantiation): Set the instantiated package entity's
23748 Package_Instantiation field.
23749 (Get_Package_Instantiation_Node): Move declaration to package spec.
23750 Retrieve the N_Package_Instantiation node when the Package_Instantiation
23752 (Check_Generic_Child_Unit): Within an inlined call, the only possible
23753 instantiation is Unchecked_Conversion, for which no parents are needed.
23754 (Inline_Instance_Body): Deinstall and record the use_clauses for all
23755 parent scopes of a scope being removed prior to inlining an instance
23757 (Analyze_Package_Instantiation): Do not perform front-end inlining when
23758 the current context is itself an instance within a non-instance child
23759 unit, to prevent scope stack errors.
23760 (Save_References): If the node is an aggregate that is an actual in a
23761 call, rewrite as a qualified expression to preserve some type
23762 information, to resolve possible ambiguities in the instance.
23763 (Instance_Parent_Unit): New global variable to record the ultimate
23764 parent unit associated with a generic child unit instance (associated
23765 with the existing Parent_Unit_Visible flag).

23767 parents recorded in the global Instance_Parent_Unit.
23768 (Init_Env): Save value of Instance_Parent_Unit in the Instance_Env
23770 (Install_Spec): Save the parent unit entity in Instance_Parent_Unit when
23771 it's not a top-level unit, and only do this if Instance_Parent_Unit is
23772 not already set. Replace test of Is_Child_Unit with test of parent's
23773 scope against package Standard. Add comments and a ??? comment.
23774 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
23775 on a child instance parent to test that the parent equals
23776 Instance_Parent rather than simply checking that the unit is not a
23778 (Restore_Env): Restore value of Instance_Parent_Unit from Instance_Env.
23779 (Validate_Derived_Interface_Type_Instance): Verify that all ancestors of
23780 a formal interface are ancestors of the corresponding actual.

23790 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
23792 (Build_Private_Derived_Type): The entity of the created full view of the
23793 derived type does not come from source. If after installing the private
23794 declarations of the parent scope the parent is still private, use its
23795 full view to construct the full declaration of the derived type.
23796 (Build_Derived_Record_Type): Relax the condition that controls the
23797 execution of the check that verifies that the partial view and
23798 the full view agree in the set of implemented interfaces. In
23799 addition, this test now only takes into account the progenitors.
23800 (Derive_Interface_Subprograms): No need to derive subprograms
23801 of ancestors that are interfaces.
23802 (Derive_Subprograms): Remove formal No_Predefined_Prims and the
23804 Change name Is_Package to Is_Package_Or_Generic_Package
23805 (Complete_Subprograms_Derivation): Handle the case in which the full
23806 view is a transitive derivation of the ancestor of the partial view.
23807 (Process_Full_View): Rename local subprogram Find_Interface_In_
23808 Descendant to Find_Ancestor_Interface to leave the code more clear.
23809 Remove wrong code that avoids the generation of an error message
23810 when the immediate ancestor of the partial view is an interface.
23811 In addition some minor reorganization of the code has been done to
23812 leave it more clear.
23813 (Analyze_Type_Declaration): If type has previous incomplete tagged
23814 partial view, inherit properly its primitive operations.
23815 (Collect_Interfaces): Make public, for analysis of formal
23817 (Analyze_Interface_Declaration): New procedure for use for regular and
23818 formal interface declarations.
23819 (Build_Derived_Record_Type): Add support for private types to the code
23820 that checks if a tagged type implements abstract interfaces.

23823 (Access_Type_Declaration): Clean up declaration of malformed type
23824 declared as an access to its own classwide type, to prevent cascaded
23826 (Collect_Interfaces): For private extensions and for derived task types
23827 and derived protected types, the parent may be an interface that must
23828 be included in the interface list.
23829 (Access_Definition): If the designated type is an interface that may
23830 contain tasks, create Master_Id for it before analyzing the expression
23831 of the declaration, which may be an allocator.
23832 (Record_Type_Declaration): Set properly the interface kind, for use
23833 in allocators, the creation of master id's for task interfaces, etc.

23836 Ed Schonberg <schonberg@adacore.com>
23838 * sem_ch6.adb (Check_Conformance): The null-exclusion feature can be
23839 omitted in case of stream attribute subprograms.
23840 (Check_Inline_Pragma): Handle Inline and Inline_Always pragmas that
23841 appear immediately after a subprogram body, when there is no previous
23842 subprogram declaration.
23843 Change name Is_Package to Is_Package_Or_Generic_Package
23844 (Process_Formals): A non null qualifier on a non null named access
23845 type is not an error, and is a warning only if Redundant_Constructs
23848 2005-11-14 Gary Dismukes <dismukes@adacore.com>
23849 Ed Schonberg <schonberg@adacore.com>
23851 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
23852 nested within Analyze_Package_Specification to install the private
23853 declarations and use clauses within each of the parent units of a
23854 package instance of a generic child package.
23855 (Analyze_Package_Specification): When entering a private part of a
23856 package associated with a generic instance or formal package, the
23857 private declarations of the parent must be installed (by calling new
23858 procedure Install_Parent_Private_Declarations).
23859 Change name Is_Package to Is_Package_Or_Generic_Package
23860 (Preserve_Full_Attributes): For a synchronized type, the corresponding
23861 record is absent in a generic context, which does not indicate a
23864 2005-11-14 Ed Schonberg <schonberg@adacore.com>
23866 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
23867 not try to rewrite a renamed stream attribute, because the operations
23868 on the type may not have been generated.
23869 Handle properly a renaming_as_body generated for a stream operation
23870 whose default is abstract because the object type itself is abstract.
23871 (Find_Type): If the type is incomplete and appears as the prefix of a
23872 'Class reference, it is tagged, and its list of primitive operations
23873 must be initialized properly.
23874 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23875 private declaration of a parent unit, prior to compiling the private
23876 part of a child unit, find on the scope stack the proper parent entity
23877 on which to link the use clause.
23878 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23880 (Analyze_Object_Renaming): An attribute reference is not a legal object
23881 if it is not a function call.

23886 * sem_eval.adb: Implement d.f flag
23887 (Subtype_Statically_Match): A generic actual type has unknown
23888 discriminants when the corresponding actual has a similar partial view.

23897 * sem_res.adb (Resolve_Call): Provide a better error message whenever
23898 a procedure call is used as a select statement trigger and is not an
23899 entry renaming or a primitive of a limited interface.
23900 (Valid_Conversion): If the operand has a single interpretation do not
23901 remove address operations.
23902 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
23903 statement to inhibit warning.
23904 (Resolve_Unary_Op): Do not produce a warning when
23905 processing an expression of the form -(A mod B)
23906 Use Universal_Real instead of Long_Long_Float when we need a high
23907 precision float type for the generated code (prevents gratuitous
23908 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23909 (Resolve_Concatenation_Arg): Improve error message when argument is an
23910 ambiguous call to a function that returns an array.
23911 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
23912 there is an implicit operator in the given scope if we are within an
23913 instance: legality check has been performed on the generic.
23914 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
23915 after resolving operand, to avoid false warnings on overloaded calls.

23924 previously detected errors to ensure that its compilation
23925 with assertions enabled gives the same output that its
23926 compilation without assertions.

23928 Change name In_Actual to In_Generic_Actual (clean up)
23929 (Disambiguate): New predicate In_Actual, to recognize expressions that

23945 for a parameterless procedure.
23946 (Enter_Name): Recognize renaming declarations created for private
23947 component of a protected type within protected operations, so that

24853 * checks.adb (Check_Needed): New procedure, deals with removing checks
24854 based on analysis of short-circuited forms. Also generates warnings for
24855 improper use of non-short-circuited forms.
24858 2005-09-01 Robert Dewar <dewar@adacore.com>
24860 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
24863 2005-09-01 Robert Dewar <dewar@adacore.com>
24865 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

24869 (conditional warning).
24870 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
24871 (Error_Msg_Warn): New variable for < insertion char.
24872 * prj-nmsc.adb: Implement new errout insertion char < (conditional
24874 (Check_For_Source): Change value of Source_Id only after the current
24875 source has been dealt with.
24877 2005-09-01 Robert Dewar <dewar@adacore.com>
24878 Doug Rupp <rupp@adacore.com>
24880 * exp_attr.adb: Handle vax fpt for 'Valid attribute
24881 * exp_vfpt.ads, exp_vfpt.adb: (Expand_Vax_Valid): New procedure

24886 Hristian Kirtchev <kirtchev@adacore.com>
24887 Javier Miranda <miranda@adacore.com>
24889 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24890 from object notation, the original node is unanalyzed and carries no
24891 semantic information, so that accessiblity checks must be performed on
24892 the type of the actual itself.
24893 (Expand_N_Subprogram_Declaration): Change last actual parameter for
24894 compatibility with Build_Protected_Sub_Specification.
24895 (Check_Overriding_Inherited_Interfaces): Add suport to handle
24896 overloaded primitives.
24897 (Register_Interface_DT_Entry): Use the new name of the formal
24898 the the calls to Expand_Interface_Thunk
24900 * exp_dbug.ads: Augment comments on encoding of protected types to
24901 include the generation of dispatching subprograms when the type
24902 implements at least one interface.
24904 * lib.ads: Extend information in Load_Stack to include whether a given
24905 load comes from a Limited_With_Clause.
24907 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24908 whether a potential circularity is harmless, because it includes units
24909 loaded through a limited_with clause. Extends previous treatment which
24910 did not handle properly arbitrary combinations of limited and
24911 non-limited clauses.
24913 2005-09-01 Nicolas Setton <setton@adacore.com>
24915 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
24916 to be encoded as typ___XBLU_lowerbound__upperbound instead of
24917 typ___XB_lowerbound__upperbound.
24919 2005-09-01 Thomas Quinot <quinot@adacore.com>
24921 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
24922 dummy access formal for RACW/RAS TypeCode TSS.
24923 (Build_TypeCode_Call): Do not generate dummy null access actual for
24924 calls to the TypeCode TSS.
24926 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24928 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
24929 fully qualified name, to distinguish instances with the same local name.
24931 * g-souinf.ads (Enclosing_Entity): Document that entity name is now

24943 (Close): Deallocate any existing filter for the concerned connection
24945 2005-09-01 Laurent Pautet <pautet@adacore.com>
24947 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24948 position set is provided, we compute one in order to reduce the maximum
24949 length of the keys. This computation first selects a character
24950 position between 1 and the minimum length of the keys in order to
24951 avoid reducing one of the keys to an empty string.
24952 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24953 does not converge. The initialization procedure now comes with a
24954 maximum number of iterations such that when exceeded, an exception is
24955 raised in Compute. The user can initialize this ratio to another value
24957 Reformating and updated headers.
24959 2005-09-01 Javier Miranda <miranda@adacore.com>
24961 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24962 that given an entity T creates and returns an Itype that duplicates the
24963 contents of T. The returned Itype has the null-exclusion
24964 attribute set to True, and its Etype attribute references T
24965 to keep the association between the two entities.
24966 Update copyright notice
24968 * sem_aggr.adb (Check_Can_Never_Be_Null,
24969 Aggregate_Constraint_Checks, Resolve_Aggregate,
24970 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
24972 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

24975 Robert Dewar <dewar@adacore.com>
24976 Hristian Kirtchev <kirtchev@adacore.com>

24984 (P_Subprogram_Specification): Add parsing of anonymous access result
24985 plus null exclusions. Call Set_Result_Definition instead of
24988 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
24989 (P_Access_Type_Definition): Add parsing for an anonymous access result
24990 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24991 instead of Set_Subtype_Mark.
24993 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
24994 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
24995 (Result_Definition): New function for N_Function_Specifications.
24996 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
24997 N_Function_Specification.
24998 (Set_Null_Exclusion_Present): Allow this flag for
24999 N_Function_Specification.
25000 (Set_Result_Definition): New procedure for N_Function_Specifications.
25001 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
25002 and N_Function_Specification.
25004 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
25005 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
25006 Add support for LIMITED NEW for Ada 2005 AI-419
25007 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
25008 syntax for anonymous access results.
25009 Replace Subtype_Mark field by Result_Definition in
25010 N_Function_Specification and N_Access_Definition specs.
25011 Add Null_Exclusion_Present to spec of N_Function_Specification.
25012 (Result_Definition): New function for N_Function_Specification and
25013 N_Access_Function_Definition.
25014 (Set_Result_Definition): New procedure for N_Function_Specification and
25015 N_Access_Function_Definition.
25017 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
25018 Result_Definition for cases of N_Access_Function_Definition and
25019 N_Function_Specification.
25020 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
25022 2005-09-01 Vincent Celier <celier@adacore.com>
25024 * lib-writ.adb: Update Copyright notice
25025 (Write_With_Lines): On platforms where file names are case-insensitive,
25026 record the file names in lower case.
25027 (Write_ALI): For D lines, on platforms where file names are
25028 case-insensitive, record the file names in lower case.
25030 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25031 Emmanuel Briot <briot@adacore.com>
25033 * lib-xref.adb (Output_Overridden_Op): Display information on
25034 overridden operation.
25036 * lib-xref.ads: Add documentation on overridden operations.
25038 * ali.ads (Xref_Entity_Record): Add support for storing the overriding

25042 overriding entity information.
25044 2005-09-01 Vincent Celier <celier@adacore.com>
25046 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
25047 including those that are inherited.
25049 2005-09-01 Robert Dewar <dewar@adacore.com>
25051 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
25053 * par-prag.adb: Implement new pragma Debug_Policy
25055 * sem_prag.adb Implement new pragma Debug_Policy
25056 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
25057 Component_Size attribute specification. Give warning for ignored pragma
25060 * snames.h, snames.ads, snames.adb: Introduce entries in
25061 Preset_Names for Name_Disp_Asynchronous_Select,
25062 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
25063 Name_Disp_Timed_Select.
25064 New pragma Debug_Policy
25066 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
25068 Switch -gnata also sets Debug_Pragmas_Enabled
25070 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
25071 handle an explicit -gnata when compiling predefined files.
25073 2005-09-01 Vincent Celier <celier@adacore.com>
25075 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
25076 directories of projects that have no Ada sources.
25078 2005-09-01 Robert Dewar <dewar@adacore.com>
25080 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
25081 (makes a difference for wide characters)
25083 * widechar.adb, widechar.ads:
25084 Add Wide_Char_Byte_Count feature to count chars vs bytes
25086 2005-09-01 Thomas Quinot <quinot@adacore.com>
25087 Ed Schonberg <schonberg@adacore.com>
25088 Robert Dewar <dewar@adacore.com>
25090 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
25091 'Address attribute reference with an overloaded prefix, use the
25092 location of the prefix (not the location of the attribute reference) as
25093 the error location.
25094 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
25095 a function renaming thereof, is a valid prefix for 'Size (where it is
25096 intepreted as a function call).
25097 (Statically_Denotes_Entity): New predicate to determine whether the
25098 prefix of an array attribute can be considered static.
25101 (Eval_Attr): Fix failure to evaluate Component_Size for
25102 unconstrained arrays (resulted in wrong value in packed case, since
25103 back end cannot handle this case)
25105 2005-09-01 Robert Dewar <dewar@adacore.com>
25107 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
25108 error msgs for most common cases.
25109 Use new errout insertion char < (conditional warning)
25111 2005-09-01 Javier Miranda <miranda@adacore.com>
25112 Ed Schonberg <schonberg@adacore.com>
25114 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
25115 become local to the whole package.
25116 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
25117 the package was already analyzed the new algorithm "replaces" the
25118 real entities by the shadow ones. This is required to ensure that
25119 the order of these entities in the homonym chains does not change;
25120 otherwise we can have undefined references at linking time because
25121 in case of conflicts the external name of the entities will have
25122 a suffix that depends on the order of the entities in the chain.
25123 (Remove_Limited_With_Clause): Complementary code that completes the
25124 new algorithm and replaces the shadow entities by the real ones.
25125 (Install_Limited_Withed_Unit): When unchaining entities before the
25126 installation of the shadow entities, only regular entities of the
25127 public part must be taken into account. This is required to
25128 keep this routine in synch with the work done by Remove_Limited_
25130 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
25131 even if unit is analyzed, because the analysis of the unit is
25132 idempotent in any case, and the limited view of the unit may have to
25133 be installed for proper visibility.
25134 (Expand_Limited_With_Clause): Even if the unit in the implicit
25135 with_clause has been analyzed already, a limited view of the package
25136 must be built for the current context, if it does not exist yet.
25138 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25139 Javier Miranda <miranda@adacore.com>
25140 Gary Dismukes <dismukes@adacore.com>
25142 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
25143 defining entity for the instance body, make a new defining identifier
25144 rather than copying the entity of the spec, to prevent accidental
25145 sharing of the entity list.
25146 (Check_Private_View): When exchanging views of private types, build the
25147 list of exchanged views as a stack, to ensure that on exit the exchanges
25148 are undone in the proper order.
25149 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
25150 Restore the compilation environment in case of instantiation_error.
25151 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
25152 for an anonymous access result.
25153 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
25154 (Formal_Entity): Handle properly the case of a formal package that
25155 denotes a generic package renaming.
25157 2005-09-01 Thomas Quinot <quinot@adacore.com>
25159 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
25160 clause if the array aggregate is surrounded by parentheses.
25162 2005-09-01 Cyrille Comar <comar@adacore.com>
25163 Gary Dismukes <dismukes@adacore.com>
25164 Ed Schonberg <schonberg@adacore.com>
25165 Javier Miranda <miranda@adacore.com>
25167 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
25169 to check if a type is Constrained in cases related to code generation
25170 (rather than semantic checking) since otherwise we do not generate
25171 similar code for mutable private types depending if their
25172 discriminants are visible or not.
25173 (Check_Abstract_Overriding): Do not complain about failure to override
25174 the primitive operations used in dispatching selects since they will
25175 always be overriden at the freeze point of the type.
25176 (Access_Definition): Separate out handling for resetting the scope
25177 of an anonymous access function result type. Retrieve the scope
25178 of the associated function rather than using Current_Scope, which
25179 does not have a consistent value (depends on whether we're in the
25180 middle of analyzing formal parameters). Add ??? comment about
25181 finding a cleaner way to handle the special cases of scope setting.
25182 (Process_Incomplete_Dependents): A protected operation is never a
25183 dispatching operation (only its wrapper may be).
25184 (Build_Derived_Record_Type): In case of tagged private types that
25185 implement interfaces add derivation of predefined primitive
25187 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
25188 by two parameters that are used in case of derivation from abstract
25189 interface types: No_Predefined_Prims is used to avoid the derivation
25190 of predefined primitives from the interface, and Predefined
25191 Prims_Only is used to complete the derivation predefined primitives
25192 in case of private tagged types implementing interfaces.
25193 Fix typo in comments
25194 (Find_Interface_In_Descendant): Protect the frontend against
25195 wrong code with large circularity chains.
25196 (Is_Private_Overriding): Add support for entities overriding interface
25197 subprograms. The test failed because Entities associated with overriden
25198 interface subprograms are always marked as hidden (and used to build
25199 the secondary dispatch table); in this case the overriden entity is
25200 available through the field abstract_interface_alias (cf. override_
25201 dispatching_operation)
25202 (Access_Definition): Set the scope of the type to Current_Scope for the
25203 case of a function with an anonymous access result type.
25204 (Access_Subprogram_Declaration): Handle creation of the type entity for
25205 an access-to-function type with an anonymous access result.
25206 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
25207 in handling for N_Access_Function_Definition.
25208 (Analyze_Subtype_Declaration): Modify the text of error message.
25209 (Derived_Type_Declaration): Modify the text of error message.
25210 (Process_Subtype): Modify the text of error message plus cleanup
25211 of one redundant error message.
25212 (Analyze_Component_Declaration): Code cleanup.
25213 (Analyze_Object_Declaration): Code cleanup.
25214 (Analyze_Subtype_Declaration): Propagate the null-exclusion
25215 attribute in case of access types. Code cleanup.
25216 (Array_Type_Declaration): Code cleanup.
25217 (Process_Discriminants): Create the new null-excluding itype
25218 if required. Code cleanup.
25219 (Process_Subtype): Create the new null-excluding itype if
25220 required. Code cleanup.
25221 (Build_Derived_Record_Type): Code cleanup to avoid calling
25222 twice the subprogram derive_subprograms in case of private
25223 types that implement interfaces. In this particular case the
25224 subprogram Complete_Subprograms_Derivation already does the
25225 job associated with the second call.
25227 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
25228 conversion to the full view when generating an operation for a
25229 discriminant whose type may currently be private.
25231 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25232 Javier Miranda <miranda@adacore.com>
25234 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
25235 V (Obj.F), the rewriting does not involve the indexed component, but
25236 only the selected component itself.
25237 Do not apply the transformation if the analyzed node is an actual of a
25238 call to another subprogram.
25239 (Complete_Object_Operation): Retain the entity of the
25240 dispatching operation in the selector of the rewritten node. The
25241 entity will be used in the expansion of dispatching selects.
25242 (Analyze_One_Call): Improve location of the error message associated
25244 (Analyze_Selected_Component): No need to resolve prefix when it is a
25245 function call, resolution is done when parent node is resolved, as
25247 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
25248 when attempting to resolve a call transformed from its object notation.
25249 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
25250 of the argument list for each interpretation of the operation.
25251 (Try_Object_Operation): The designated type of an access parameter may
25252 be an incomplete type obtained through a limited_with clause, in which
25253 case the primitive operations of the type are retrieved from its full
25255 (Analyze_Call): If this is an indirect call, and the return type of the
25256 access_to_subprogram is incomplete, use its full view if available.
25258 2005-09-01 Javier Miranda <miranda@adacore.com>
25259 Gary Dismukes <dismukes@adacore.com>
25261 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
25262 access types the null-exclusion and access-to-constant attributes must
25264 (Analyze_Return_Statement): When the result type is an anonymous access
25265 type, apply a conversion of the return expression to the access type
25266 to ensure that appropriate accessibility checks are performed.
25267 (Analyze_Return_Type): For the case of an anonymous access result type,
25268 generate the Itype and set Is_Local_Anonymous_Access on the type.
25269 Add ??? placeholder for check to disallow returning a limited object
25270 in Ada 2005 unless it's an aggregate or a result of a function call.
25271 Change calls from Subtype_Mark to Result_Definition.
25272 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
25273 Result_Definition in call to Make_Function_Specification.
25274 (Build_Body_To_Inline): Change Set_Subtype_Mark to
25275 Set_Result_Definition.
25276 (Make_Inequality_Operator): Change formal Subtype_Mark to
25277 Result_Definition in call to Make_Function_Specification.
25278 (Process_Formals): Create the new null-excluding itype if required.
25279 (New_Overloaded_Entity): For an entity overriding an interface primitive
25280 check if the entity also covers other abstract subprograms in the same
25281 scope. This is required to handle the general case, that is, overriding
25282 other interface primitives and overriding abstract subprograms inherited
25283 from some abstract ancestor type.
25284 (New_Overloaded_Entity): For an overriding entity that comes from
25285 source, note the operation that it overrides.
25286 (Check_Conformance, Type_Conformant): Addition of one new formal
25287 to skip controlling formals in the analysis. This is used to
25288 handle overloading of abstract interfaces.
25289 (Base_Types_Match): Add missing case for types imported from
25290 limited-with clauses
25291 (New_Overloaded_Entity): Add barrier to protect the use of
25292 the "alias" attribute.
25294 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25296 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
25297 verify that the procedure and the entry are mode conformant.
25298 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
25299 as a different operator, which is often a cut-and-paste error.
25301 2005-09-01 Javier Miranda <miranda@adacore.com>
25302 Ed Schonberg <schonberg@adacore.com>
25304 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
25305 used in controlling parameters exclude null because it is necessary to
25306 read the tag to dispatch, and null has no tag.
25307 (Override_Dispatching_Operation): If the previous operation is inherited
25308 from an interface, it becomes hidden and does not participate in later

25312 Ed Schonberg <schonberg@adacore.com>
25313 Gary Dismukes <dismukes@adacore.com>
25315 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
25316 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
25317 the expander will generate the corresponding run-time check to evaluate
25319 (Resolve_Call): Check for legal type of procedure name or prefix that
25320 appears as a trigger in a triggering alternative.
25321 (Valid_Conversion): If expression is ambiguous and the context involves
25322 an extension of System, remove System.Address interpretations.
25323 (Resolve_Qualified_Expression): Reject the case of a specific-type
25324 qualification applied to a class-wide argument. Enhance comment
25325 to explain checking of Original_Node.
25326 (Resolve_Type_Conversion): The location of the error message was not
25327 general enough to handle the general case and hence it has been removed.
25328 In addition, this patch improves the text of the message.
25329 (Resolve_Type_Conversion): Add missing support for access to interface
25331 (Resolve_Type_Conversion): If the target is a class-wide interface type,
25332 do not expand if the expression is the actual in a call, because proper
25333 expansion will take place when the call itself is expanded.
25334 (Resolve_Allocator): If the context is an unchecked conversion, the
25335 allocator inherits its storage pool, if any, from the target type of

25339 Javier Miranda <miranda@adacore.com>
25341 * sem_type.adb (Add_One_Interp): If a candidate operation is an
25342 inherited interface operation that has an implementation, use the
25343 implementation to avoid spurious ambiguities.
25344 (Interface_Present_In_Ancestor): In case of concurrent types we can't
25345 use the Corresponding_Record_Typ attribute to look for the interface
25346 because it is set by the expander (and hence it is not always
25347 available). For this reason we traverse the list of interfaces
25348 (available in the parent of the concurrent type).
25349 (Interface_Present_In_Ancestor): Handle entities from the limited view
25351 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25353 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
25354 from the list of required components.

25356 primitive procedure of a limited interface with a controlling first
25358 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
25360 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
25361 capture if it is generated in the second operand of a short-circuit
25363 Do not capture values for variables with address clauses.
25364 (Is_Object_Reference): Treat a function call as an object reference only
25365 if its type is not Standard_Void_Type.
25367 2005-09-01 Ed Schonberg <schonberg@adacore.com>
25369 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
25370 to a variable that is statically known to be constant.

26152 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
26153 longer protected objects. They have been replaced by lower-level
26154 suspension objects made up by a mutex and a condition variable (or
26155 their equivalent given a particular OS) plus some internal data to
26156 reflect the state of the suspension object.
26157 (Initialize, Finalize): Add this initialization procedure for
26158 Suspension_Object, which is a controlled type.
26159 (Finalize): Add the finalization procedure for Suspension_Object,
26160 which is a controlled type.

26186 (Suspend_Until_True): Add this procedure that blocks the calling task
26187 until the state of the object is True. Program_Error is raised if
26188 another task is already waiting on that suspension object.
26189 (Initialize): Add this procedure for initializing the suspension
26190 object. It initializes the mutex and the condition variable which are
26191 used for synchronization and queuing, and it sets the internal state

26562 * i-cpp.ads, i-cpp.adb:
26563 This package has been left available for compatibility with previous

26608 (Analyze_Subprogram_Body): Undo the previous work.
26609 (Analyze_Procedure_Call): If the call has the form Object.Op, the
26610 analysis of the prefix ends up analyzing the call itself, after which

26613 subprogram_specification that returns true if some non
26614 class-wide interface subprogram is found

26618 access to subprograms must be recursive.
26619 (Is_Unchecked_Conversion): Improve the test that recognizes
26620 instantiations of Unchecked_Conversion, and allows them in bodies that
26621 are to be inlined by the front-end. When the body comes from an

26644 object or component (that is, when Is_Local_Anonymous_Access is true).
26645 Prevent the special checks for conversions of access discriminants in
26646 the case where the discriminant belongs to a nonlimited type, since
26647 such discriminants have their accessibility level defined in the same
26648 way as a normal component of an anonymous access type.
26649 (Resolve_Allocator): When an allocator's designated type is a class-wide
26650 type, check that the accessibility level of type given in the
26651 allocator's expression or subtype indication is not statically deeper

26668 pragma Restrictions (No_Obsolescent_Features).
26669 (Check_Direct_Boolean_Operator): If the boolean operation has been
26670 constant-folded, there is nothing to check.
26671 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
26672 check on possible violation of restriction No_Direct_Boolean_Operators
26673 until after expansion of operands, to prevent spurious errors when

26953 * exp_aggr.adb (Aggr_Size_OK): An array with no components can always
26954 be expanded in place. The size computation does not require a

26956 assertions when the upper bound is Integer'first.
26957 (Flatten): For an array of composite components, take into account the
26958 size of the components to determine whether it is safe to expand the

26976 the "simple_choice" member in a variant record, in accordance with the
26977 description in the package spec: the information output for a constant
26978 should be "S number", not "SS number".
26979 (Get_Encoded_Name): Return at once if not generating code. Avoids name

27036 failure of our own connect(2) call.
27037 (Check_Selector): Improve documentation of the selector mechanism.
27038 (Broadcast_Inet_Addr): New constant.

27045 of the type is declared in a record (for determination of insertion
27047 (SO_Ref_From_Expr): Test whether Vtype denotes a partial or full view of

27071 (Analyze_Context): Limited-with clauses are now allowed
27072 in more compilation units.

27074 againts previously reported critical errors in context clauses
27075 (Install_Limited_Withed_Unit): Code cleanup plus static detection

27096 (Get_Type_Reference): For a subtype that is the renaming of an actual in
27097 an instantiation, use the first_subtype to ensure that we don't generate

27630 (check dos line terminator).
27631 (Check_Line_Max_Length): New procedure, split off from the existing
27632 Check_Line_Terminator routine. Separating this out allows -gnatyf to
27633 be properly recognized.
27635 * styleg.adb: Add ??? comment for line terminator reference

27678 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
27679 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
27680 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
27681 analyzed if expansion is disabled (which could otherwise cause spurious
27682 error messages if expansion has been disabled due to previous
27683 (unrelated) errors).
27685 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
27686 is disabled, the entity denoted by the argument is the access type
27687 itself, not an underlying record type, so there is no need to go back
27688 to the Corresponding_Remote_Type.
27690 2005-03-29 Gary Dismukes <dismukes@adacore.com>
27691 Robert Dewar <dewar@adacore.com>
27693 * exp_intr.adb (Expand_Dispatching_Constructor_Call): New procedure to
27694 expand a call to an instance of
27695 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
27696 Constructor actual of the instance. A class-wide membership
27697 check is also generated, to ensure that the tag passed to the instance
27698 denotes a type in the class.
27699 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
27700 of Name_Generic_Dispatching_Constructor.
27702 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
27703 05 unit for AI-260-02).

27715 character type cases.
27716 (Analyze_Subprogram_Renaming): Add special handling for
27717 the case of renaming of stream attributes when the renaming denotes a
27718 generic formal subprogram association for an abstract formal subprogram.
27719 Check that the attribute is a primitive stream attribute (and not
27720 a class-wide stream attribute) and then rewrite the attribute name
27721 as the name of the appropriate compiler-generated stream primitive.
27723 2005-03-29 Robert Dewar <dewar@adacore.com>
27725 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
27727 (Is_Possibly_Unaligned_Object): Correct typo that
27728 resulted in inaccurate result for unaligned scalars within records.
27730 2005-03-29 Ed Schonberg <schonberg@adacore.com>
27732 * freeze.adb (Freeze_Record_Type): If the type of the component is an
27733 itype whose parent is controlled and not yet frozen, do not create a
27734 freeze node for the itype if expansion is disabled.
27736 2005-03-29 Vincent Celier <celier@adacore.com>
27738 * make.adb (Gnatmake): Don't fail if the main project file is declared
27739 as having no Ada sources. Do not display message "no sources to
27740 compile" in quiet output.
27742 2005-03-29 Doug Rupp <rupp@adacore.com>
27744 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

27755 missing TYPE Improve the error message generated when compiling a
27756 limited interface in Ada83 or Ada95 mode.
27758 2005-03-29 Robert Dewar <dewar@adacore.com>
27760 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
27761 rather than proceed ahead using a junk attribute name.
27763 2005-03-29 Vincent Celier <celier@adacore.com>
27765 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
27767 * prj-part.adb (Parse_Single_Project): Set the location of a project
27768 on its defining identifier, rather than on the reserved word "project".
27770 * prj-proc.adb (Expression): Adapt to the fact that default of external
27771 references may be string expressions, not always literal strings.
27772 (Recursive_Process): Set Display_Name equal to Name
27773 when Location is No_Location, that is when there is no actual file.
27774 Get the Display_Name of the project from the source, when it is not a
27776 (Process): Use the Display_Name in error messages
27778 * prj-strt.adb (External_Reference): Allow default to be string
27779 expressions, not only literal strings.
27781 2005-03-29 Vincent Celier <celier@adacore.com>
27783 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
27784 file and the reference symbol file to be the same file.
27786 2005-03-29 Thomas Quinot <quinot@adacore.com>
27788 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
27789 forbid conversion of a local access-to-subprogram type to a remote one.
27791 * sem_util.adb (Wrong_Type): For a record type that is the expanded
27792 equivalent type for a remote access-to-subprogram type, go back to the
27793 original RAS entity when displaying an error message, so the casing is
27794 the original source casing.
27796 2005-03-29 Robert Dewar <dewar@adacore.com>
27798 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
27801 2005-03-29 Ed Schonberg <schonberg@adacore.com>
27803 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
27804 subtype if code is being pre-analyzed, to prevent un-expanded
27805 references to protected formals, among others.
27806 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
27807 interpretation that can be a call, include the result of the call as a
27808 possible interpretation of the dereference.
27810 * sem_ch5.adb (Process_Bounds): Determine type of range by
27811 pre-analyzing a copy of the original range, and then analyze the range
27812 with the expected type.
27814 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
27815 with an overloaded prefix where not all interpretations yield an
27816 access to subprogram, do not rewrite node as a call.
27817 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
27818 the node as a call once the context identifies the interpretation of
27819 the prefix whose call yields the context type.
27820 (Valid_Conversion): For the case of a conversion between
27821 local access-to-subprogram types, check subtype conformance using
27822 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
27823 detailed error message.
27825 2005-03-29 Ed Schonberg <schonberg@adacore.com>
27827 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
27828 indicator, indicate that the formal can never be null.
27829 (Process_Formals): If a formal has a non_null indicator, insert the
27830 resulting subtype immediately before the enclosing subprogram decl,
27831 and not at the beginning of the corresponding declarative part, to
27832 prevent access before elaboration (Ada2005).
27834 2005-03-29 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27837 * utils.c (finish_record_type): Use variable_size when setting sizes.

28399 * a-suteio.adb: Avoid unnecessary use of Get/Set_String
28401 * g-spipat.ads, g-spipat.adb: New interface for Get_String
28402 Minor reformatting (function specs)
28404 * g-spitbo.adb: New interface for Get_String
28406 * g-spitbo.ads: Minor reformatting
28408 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
28410 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String

28413 Robert Dewar <dewar@adacore.com>
28414 Thomas Quinot <quinot@adacore.com>
28415 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28417 * atree.ads, atree.adb: Add support for Elist24 field
28419 * atree.h: Fix wrong definition of Field27
28420 Add support for Elist16 field
28421 Add support for Elist24 field
28423 * einfo.ads, einfo.adb (Abstract_Interfaces,
28424 Set_Abstract_Interfaces): New subprograms.
28425 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
28427 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
28428 entities rather than a single node.

28430 (First_Tag_Component): New syntesized attribute
28431 (Next_Tag_Component): New synthesized attribute

28435 (Task_Body_Procedure): New subprogram to read this attribute.
28436 (Set_Task_Body_Procedure): New subprogram to set this attribute.
28437 (Has_Controlled_Component): Now applies to all entities.
28438 This is only a documentation change, since it always worked to apply
28439 this to other than composite types (yielding false), but now this is
28441 Update documentation on Must_Be_Byte_Aligned for new spec
28443 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
28444 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
28445 uses of the Access_Disp_Table attribute to reference the first dispatch
28446 table associated with a tagged type. As
28447 part of the implementation of abstract interface types,
28448 Access_Disp_Table has been redefined to contain a list of dispatch
28449 tables (rather than a single dispatch table).
28450 Similarly, upgrade all the references to Tag_Component by the
28451 new attribute First_Tag_Component.
28452 (Find_Inherited_TSS): Moved to exp_tss.
28453 Clean up test in Expand_N_Object_Declaration for cases
28454 where we need to do a separate assignment of the initial value.
28455 (Expand_N_Object_Declaration): If the expression in the
28456 declaration of a tagged type is an aggregate, no need to generate an
28457 additional tag assignment.
28458 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
28460 Bit packed array ops are only called if operands are known to be
28462 (Component_Equality): When returning an N_Raise_Program_Error statement,
28463 ensure that its Etype is set to Empty to avoid confusing GIGI (which
28464 expects that only expressions have a bona fide type).
28465 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
28466 determine the amount of data to be copied.
28468 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
28469 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
28470 INTERFACE_TYPE_DEFINITION ::=
28471 [limited | task | protected | synchronized] interface
28472 [AND interface_list]
28474 * par-ch3.adb (P_Type_Declaration): Modified to give support to
28476 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
28478 (P_Interface_Type_Definition): New subprogram that parses the new
28479 syntax rule of Ada 2005 interfaces
28480 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
28481 messages by the correct RENAMES (quotes removed).
28483 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
28484 attribute First_Tag_Component.
28486 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
28487 (Interface_List, Set_Interface_List): New subprograms.
28488 (Interface_Present, Set_Interface_Present): New subprograms.
28489 (Limited_Present, Set_Limited_Present): Available also in derived
28490 type definition nodes.
28491 (Protected_Present, Set_Protected_Present): Available also in
28492 record type definition and
28493 derived type definition nodes.
28494 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
28495 (Task_Present, Set_Task_Present): New subprogram.
28496 (Task_Body_Procedure): Removed.
28497 (Set_Task_Body_Procedure): Removed.
28498 These subprogram have been removed because the attribute
28499 Task_Body_Procedure has been moved to the corresponding task type
28500 or task subtype entity to leave a field free to store the list
28501 of interfaces implemented by a task (for AI-345)
28502 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
28503 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
28504 expression flag Do_Range_Check
28505 (Exception_Junk): Change to Flag7 to accomodate above change
28506 (Box_Present, Default_Name, Specification, Set_Box_Present,
28507 Set_Default_Name, Set_Specification): Expand the expression
28508 "X in N_Formal_Subprogram_Declaration" into the corresponding
28509 two comparisons. Required to use the csinfo tool.
28511 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
28512 "with string" given.
28514 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
28517 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
28520 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
28521 attribute Task_Body_Procedure rather than the old semantic field that
28522 was available in the task_type_declaration node.
28524 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
28525 interface type definitions.
28526 (P_Formal_Derived_Type_Definition): Modified to handle the list of
28529 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
28530 task type declaration.
28531 (P_Protected): Modified to handle the list of interfaces in a
28532 protected type declaration.
28534 2005-03-15 Doug Rupp <rupp@adacore.com>
28535 Vincent Celier <celier@adacore.com>
28537 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
28538 (Gen_Output_File_C): Likewise.
28539 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
28541 2005-03-15 Thomas Quinot <quinot@adacore.com>
28543 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
28544 is an N_Raise_Constraint_Error node, create a new copy of it without
28545 going through a call to Duplicate_Subexpr.
28547 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
28548 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28549 Nicolas Setton <setton@adacore.com>
28550 Ed Schonberg <schonberg@adacore.com>
28556 * decl.c (gnat_to_gnu_field): Reject aliased components with a
28557 representation clause that prescribes a size not equal to the rounded
28558 size of their types.
28559 (gnat_to_gnu_entity, case E_Component): Always look at
28560 Original_Record_Component if Present and not the entity.
28561 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
28562 of tagged extension types by not making field for components that are
28564 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
28565 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
28566 expression to the type of the object when the object is constant.
28567 Reverse defer_debug_incomplete_list before traversing it, so that trees
28568 are processed in the order at which they were added to the list. This
28569 order is important when using the stabs debug format.
28570 If we are deferring the output of debug information, also defer this
28571 output for a function return type.
28572 When adding fields to a record, prevent emitting debug information
28573 for incomplete records, emit the information only when the record is
28575 (components_to_record): New parameter defer_debug.
28576 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
28577 (gnat_to_gnu_field_decl): New function.
28578 (substitution_list, annotate_rep): Call it.
28579 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
28580 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
28581 No longer update discriminants to not be a COMPONENT_REF.
28582 (copy_alias_set): Strip padding from input type; also handle
28583 unconstrained arrays properly.
28585 * gigi.h (write_record_type_debug_info): New function.
28586 Convert to use ANSI-style prototypes. Remove unused
28587 declarations for emit_stack_check, elab_all_gnat and
28588 set_second_error_entity.
28589 (gnat_to_gnu_field_decl): New decl.
28591 * utils.c (write_record_type_debug_info): New function.
28592 (finish_record_type): Delegate generation of debug information to
28593 write_record_type_debug_info.
28594 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
28595 (update_pointer_to): Fix pasto.
28596 (convert) <UNION_TYPE>: Accept slight type variations when
28597 converting to an unchecked union type.
28599 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
28600 replace the N_Freeze_Entity with a null statement.
28602 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
28603 within a constrained subcomponent of an enclosing record, place the
28604 freeze nodes in the scope stack entry for the enclosing record.
28605 (Undelay_Type): New Subprogram.
28606 (Set_Small_Size): Pass T, the type to modify; all callers changed.
28607 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
28608 within records; allow them to have freeze nodes if their base types
28611 * exp_util.adb (Remove_Side_Effects): Properly test for
28612 Expansion_Delayed and handle case when it's inside an
28613 N_Qualified_Expression.
28615 * sem_ch3.adb (Derived_Type_Declaration): New predicate
28616 Comes_From_Generic, to recognize accurately that the parent type in a
28617 derived type declaration can be traced back to a formal type, because
28618 it is one or is derived from one, or because its completion is derived
28620 (Constrain_Component_Type): If component comes from source and has no
28621 explicit constraint, no need to constrain in in a subtype of the
28623 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
28624 Minor change to propagate Is_Ada_2005 flag
28626 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
28627 Expansion_Delayed is False.
28628 (assoc_to_constructor): Ignore fields that have a
28629 Corresponding_Discriminant.
28630 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
28631 function returns "by target", dereference the target pointer using the
28632 type of the actual return value.
28633 <all>: Be prepared for a null gnu_result.
28634 (processed_inline_subprograms): Check flag_really_no_inline
28635 instead of flag_no_inline.
28636 (set_second_error_entity): Remove unused function.
28637 (gnat_to_gnu, case N_Selected_Component): Call
28638 gnat_to_gnu_field_decl.

28641 2005-03-15 Robert Dewar <dewar@adacore.com>
28642 Ed Schonberg <schonberg@adacore.com>
28643 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28645 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
28646 Must_Be_Byte_Aligned for cases where we do not need to use a
28647 System.Pack_nn unit.
28649 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
28651 Needed now that we do some processing for IN parameters as well. This
28652 may well fix some unrelated errors.
28653 (Expand_Call): Handle case of unaligned objects (in particular those
28654 that come from packed arrays).
28655 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
28656 renamed entity is an inherited operation, re-expand the call using the
28657 original operation, which is the one to call.
28658 Detect attempt to inline parameterless recursive subprogram.
28659 (Represented_As_Scalar): Fix to work properly with private types
28660 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
28661 accurate estimate. Yields True in far fewer cases than before,
28662 improving the quality of code that depends on this test.
28664 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
28665 over both visible and private declarations to remove them from tree,
28666 and mark subprograms declared in package as eliminated, to prevent
28667 spurious use in subsequent compilation of generic units in the context.
28669 * exp_util.ads: Minor cleanup in variable names
28671 * sem_eval.ads, sem_eval.adb: Minor reformatting
28672 (Compile_Time_Known_Bounds): New function
28674 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28676 * exp_ch7.adb (Convert_View): Use base types of underlying types when
28677 determining whether an unchecked conversion is needed for the argument
28678 of an initialization call.
28680 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28682 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
28683 that appears in the instantiation rather than the internal subtype
28684 generated in the wrapper package, to avoid anomalies in gigi when the
28685 target is derived from a private type whose full view is an access type.
28687 2005-03-15 Robert Dewar <dewar@adacore.com>
28689 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
28691 Add documentation to replace the use of this flag
28692 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
28695 2005-03-15 Thomas Quinot <quinot@adacore.com>
28697 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
28698 here from exp_attr so it can be shared between exp_attr and exp_dist.
28699 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
28700 all TSS names, not a subset thereof, and the previous name introduced
28701 an unnecessarily confusion that a distinction might exist between
28702 "OK" TSS names and some "not OK" TSS names.
28704 2005-03-15 Doug Rupp <rupp@adacore.com>
28706 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
28709 2005-03-15 Pascal Obry <obry@adacore.com>
28710 Eric Botcazou <ebotcazou@adacore.com>
28714 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
28715 when IN_RTS. This is to work around a bootstrap path problem.
28717 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
28718 table and pass it to __gnat_install_SEH_handler().
28719 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
28721 * lang.opt: Fix specification of -fRTS=.
28723 2005-03-15 Doug Rupp <rupp@adacore.com>
28724 Bernard Banner <banner@adacore.com>
28725 Vincent Celier <celier@adacore.com>
28726 Arnaud Charlet <charlet@adacore.com>
28729 This change works fine when gnatlib is built from the gcc directory,
28730 but does not work when using the libada Makefile, since GCC_FOR_TARGET
28731 is not passed to ada/Makefile.in, so more work is needed by a
28732 Makefile/configure expert.
28734 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
28735 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
28736 Setup gnatlink switch -M for x86_64 linux, as it is already setup
28738 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
28739 Run ranlib on libgccprefix.a
28740 Define PREFIX_OBJS for Darwin, to build libgccprefix.
28741 (ADA_INCLUDE_SRCS): Split Ada packages.
28743 2005-03-15 Robert Dewar <dewar@adacore.com>
28745 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
28747 * impunit.adb: Add GNAT.UTF_32
28749 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
28751 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
28752 now uses GNAT.UTF_32).
28754 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
28755 capabilities for categorizing characters using Unicode categories
28757 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28759 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
28760 instantiation that has been rewritten as a package body, retrieve spec
28761 to generate proper name for implicit_with_clause.
28762 (Install_Parents): Recognize a parent that is an instantiation but has
28763 been rewritten as a package declaration during analysis.
28765 2005-03-15 Javier Miranda <miranda@adacore.com>
28766 Ed Schonberg <schonberg@adacore.com>
28768 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
28769 parameter reported some error we immediately return. This improves the
28770 behaviour of the frontend in case of errors.
28771 (Install_Parent, Remove_Parent): Introduce new flag
28772 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
28773 ancestor of a generic child unit, when the child is being instantiated.
28774 (Inline_Instance_Body): If we are compiling the private
28775 part or the body of a child unit, restore the proper visibility of the
28776 parents after compiling the instance body.
28778 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28779 Javier Miranda <miranda@adacore.com>
28782 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28783 of a private type, in which case it is underlying_type that denotes
28784 the proper task. Also modified to use the new entity attribute
28785 that is directly available in the task type and task subtype entities
28786 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28787 arrays when other dimensions than the first are constrained by
28788 discriminants of an enclosing record.
28789 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28790 a combination of indexed and selected components, find ultimate entity
28791 and generate the appropriate reference for it, to suppress spurious
28793 (Note_Possible_Modification): If an entity name has no entity, return.
28794 (Is_Variable): A function call never denotes a variable.
28795 (Requires_Transient_Scope): For record types, recurse only on
28796 components, not on internal subtypes that may have been generated for
28797 constrained components.
28799 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28801 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28802 Eliminated as candidates for resolution. Both efficient, and avoids
28803 anomalies with operators declared in deleted code.
28804 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28805 expansion is disabled (as when compiling a generic) to prevent spurious
28806 warnings on prefixes of selected components.
28808 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28810 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28811 attached to a list before checking whether it appears in the private
28812 declarations of the current package.
28813 (Make_Inequality_Operator): Insert declaration in proper declarative
28814 list rather than just setting the Parent field, so that
28815 Is_Private_Declaration can handle it properly.
28817 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28819 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28820 a renaming a body, check that the renamed subprogram in not intrinsic.
28821 (Find_Direct_Name): If several use_visible entities hide
28822 each other, and the context is a predefined file compiled through
28823 rtsfind, keep only the entity that comes from a predefined file.
28825 2005-03-15 Geert Bosch <bosch@adacore.com>
28827 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28828 long float padding to also cover AMD64 and IA64.
28830 2005-03-15 Gary Dismukes <dismukes@adacore.com>
28832 * s-imgwch.adb: Add with and use of Interfaces.
28833 (Img_Wide_Character): Change type of Val to Unsigned_16.
28834 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
28836 2005-03-15 Matthew Gingell <gingell@adacore.com>
28838 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
28840 2005-03-15 Robert Dewar <dewar@adacore.com>
28842 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
28844 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
28846 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
28848 2005-03-15 Robert Dewar <dewar@adacore.com>

29167 value by a warning message.
29168 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted

29287 describing the new layout.
29288 (Dispatch_Table): The expander computes the actual array size, allocates
29289 the Dispatch_Table record accordingly, and generates code that displaces
29290 the base of the record after the Typeinfo_Ptr component. The access to
29291 these components is done by means of local functions.
29292 (Offset_To_Top): New function.

29308 dispatching, setting the controlling status of the formal parameters
29309 and result, and issuing an error if there is no controlling type for
29310 the formal subprogram.
29311 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
29312 which is an unclean use of that field, we set the new field
29313 Corresponding_Formal_Spec to make the formal subprogram available to

29326 subprogram only if inner one comes from source.
29327 (Analyze_Function_Call): If the call is given in object notation, the

29329 argument list. After analyzing the name, if the call has been rewritten
29330 and the result type is set, no further analysis is needed.
29331 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
29332 mark in function specification, in a context where the formals are
29333 visible and hide outer homographs.
29335 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
29336 as the tagged type for the cases of abstract formal subprograms and
29337 renamings of those. Clean up spec comments.
29338 (Check_Dispatching_Context): Add error message to indicate "abstract
29339 procedure", covering the case of a call to a formal abstract procedure
29340 that has statically tagged operands.
29341 (Check_Dispatching_Call): Check for the case of an actual given by
29342 a tag-indeterminate function call whose type is an ancestor of the
29343 containing call's associated tagged type. This situation can occur
29344 for inherited primitives with function defaults. In this case we
29345 use the tagged type's tag directly as the controlling argument for

29422 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29426 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
29427 on the field if Pragma Component_Alignment (Storage_Unit).
29428 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
29429 side-effects as if it were a constant; also make SAVE_EXPR to protect

29447 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29449 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
29450 component of an array of arrays in an assignment context, and the
29451 aggregate has component associations that require sliding on
29452 assignment, force reanalysis of the aggregate to generate a temporary
29453 before the assignment.

29472 Arnaud Charlet <charlet@adacore.com>
29474 * init.c (__gnat_initialize): Add a new parameter eh which contains the
29475 address of the exception registration. The Win32 version of this
29476 routine calls __gnat_install_SEH_handler() to initialize the SEH
29477 (Structured Exception Handling) handler.
29478 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
29479 SEH (Structured Exception Handling) now.
29480 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
29481 (__gnat_initialize for ppc-vxworks): Adjust comments and the
29482 preprocessor condition protecting the call to the extra eh setup
29483 subprogram, which is only available for the ppc target.
29484 (__gnat_clear_exception_count): replaced reference to
29485 variable taskIdCurrent by call to taskIdSelf(), cleaner.

29494 for the SEH (Structured Exception Handling) support.
29496 * raise.h: (__gnat_install_SEH_handler): New prototype.
29497 Update copyright notice.
29499 * s-tassta.adb (Task_Wrapper): Declare the exception registration

29529 2005-02-09 Vincent Celier <celier@adacore.com>
29531 * prj-makr.adb (Process_Directory): Put file name in canonical case
29532 before matching against the patterns.
29533 If gnatname has been invoked as <prefix>-gnatname
29534 then invoke the compiler as <prefix>-gcc, not just "gcc".
29536 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29538 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
29539 with expansion disabled. The actual subtype is needed among other
29540 places when the selected component appears in the context of a loop
29541 bound, and denotes a packed array.
29542 (Operator_Check): Always use the first subtype in the
29543 error message, to avoid the appearance of internal base types.
29544 (Transform_Object_Operation): Copy each actual in full
29545 to the parameter associations of the constructed call, rather than
29546 using the shallow copy mechanism of New_Copy_List. This ensures that
29547 the chaining of named associations is done properly.
29548 (Complete_Object_Operation): Rewrite node, rather than
29549 replacing it, so that we can trace back to the original selected
29552 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
29553 and calls that use object notation, if the called function is not
29554 declared in a withed unit, place the elaboration constraint on the
29555 unit in the context that makes the function accessible.
29556 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
29557 imposes an elaboration constraint between two packages.
29559 2005-02-09 Ed Schonberg <schonberg@adacore.com>
29561 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
29562 views of a private type after handling its private dependents, to
29563 maintain proper stack discipline between entry and exit from the

29589 we now use by default.
29591 * xsnames.adb: Adjust end of file test to look for five space followed
29592 by '#' instead of six spaces. The format of xsnames.adb was modified
29593 in the last update.
29595 * a-numeri.ads: Add reference to AI-388 for greek letter pi
29598 * clean.adb: Minor reformatting.
29600 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,

29606 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
29609 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
29611 2005-02-09 Sergey Rybin <rybin@adacore.com>
29613 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
29614 the difference between compact and incompact layout and add the record
29615 representation clause to the example illustrating different layouts.
29616 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
29617 component clauses").
29619 2005-02-09 Florian Villoing <villoing@adacore.com>
29621 * gnat_ugn.texi: Fix typos.
29622 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

29669 * exp_util.ads: Minor correction in comment.
29671 2005-02-09 Arnaud Charlet <charlet@adacore.com>
29673 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,

30340 Ed Schonberg <schonberg@adacore.com>
30342 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
30343 with an implicit dereference as its prefix, use
30344 Insert_Explicit_Dereference instead of merely rewriting the prefix into
30345 an explicit dereference. This ensures that a reference to the original
30346 prefix is generated, if appropriate.
30348 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
30349 dereference is rewritten to an explicit one, generate a reference to
30350 the entity denoted by its prefix using the original prefix node, so
30351 the dereference can be properly recorded as a read of the denoted
30352 access value, if appropriate.
30354 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
30355 emitting 'assigned but never read' warning on a variable on the basis
30356 that it has an access type.
30357 (Check_References): Emit unreferenced warning when the scope is a

30366 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
30367 leaving call unchanged.
30368 This deals with the case where the pragma Import specified
30369 an external name, to be handled by the back end.
30371 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
30372 subprogram which is Imported with convention Intrinsic if an
30373 External_Name argument is specified.
30374 (Process_Import_Or_Interface): Properly diagnose link name argument.
30375 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
30376 with Sem_Ch6.Cannot_Inline.
30377 (Process_Inline): Provide separate warning for inapplicable inline
30379 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
30380 treatment is uniform on different targets.
30382 2004-12-07 Ed Schonberg <schonberg@adacore.com>
30384 * exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
30385 construct is rewritten, preserve end label to permit source navigation.

30390 Specific_Build_Stub_Target): New subprograms.
30391 (Build_Subprogram_Calling_Stubs): Make this procedure independent from
30392 the PCS implementation used, using the above PCS-customized subprograms.
30393 Minor reformatting.
30394 (PolyORB_Support.Helpers): New subunit containing supporting subprograms
30395 for generation of DSA code targeted to the PolyORB PCS.

30397 implementation of the partition communication subsystem in ancillary
30399 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
30400 PolyORB_Support.Build_Stub_Type): New subrograms containing the
30401 PCS-specific part of Add_Stub_Type.
30402 (Insert_Partition_Check): Use runtime library function to perform
30405 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
30406 (RE_Same_Partition): New entity, from s-parint.
30408 * s-parint.ads, s-parint.adb (Same_Partition): New subprogram.

30425 2004-12-07 Ed Schonberg <schonberg@adacore.com>
30428 (Generate_Reference): Handle properly a reference to an entry formal,
30429 when an accept statement has a pragma Unreferenced for it.
30431 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
30432 and the Has_Pragma_Unreferenced flag for each formal before analyzing
30433 the body, to ensure that warnings are properly emitted for each accept
30434 statement of a given task entry.
30436 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
30438 * Makefile.in: Add support for foreign threads on VMS.

30456 (Remove_Next_Debug): Same fix
30458 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
30459 maintain back pointers now, though we did not used to, and comments
30461 (Prepend): Remove pragma Inline.
30462 (Remove_Next): Same cleanup
30464 2004-12-07 Thomas Quinot <quinot@adacore.com>
30466 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
30467 used to record an implicit dereference as a read operation on its
30468 prefix when operating under -gnatc. Necessary to avoid spurious
30469 'variable assigned but never read' warnings in that mode.
30470 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
30471 is a non-overloaded implicit dereference, call the above subprogram to
30472 ensure proper recording of references.
30474 2004-12-07 Gary Dismukes <dismukes@adacore.com>
30476 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
30477 to be resolved later as part of Analyze_Iteration_Scheme's call to
30480 2004-12-07 Ed Schonberg <schonberg@adacore.com>
30482 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

30522 Add gnatmetric section
30524 2004-12-07 Vincent Celier <celier@adacore.com>
30526 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
30527 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
30528 and -eit to -ept. Added qualifier
30529 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
30531 2004-11-27 Andreas Schwab <schwab@suse.de>
30533 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
30535 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30537 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
30538 internal implementation unit GNAT.Sockets.Thin,
30539 as their usage for sockets is non-portable (using the read and write
30540 functions from the system runtime library is fine on UNIX but won't
30541 work under Windows).
30543 * mingw32.h: Update copyright notice.
30545 2004-11-25 Arnaud Charlet <charlet@adacore.com>
30547 * ada-tree.h: Minor reformatting of previous change to avoid lines
30548 longer than 79 characters.

30588 2004-11-18 Olivier Hainque <hainque@adacore.com>
30590 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
30591 address of which may be used to represent "others" and "all others"
30592 choices in exception tables, instead of the current harcoded
30593 (void *)0 and (void *)1.
30594 (Setup_Exception): Do nothing in the GNAT SJLJ case.
30596 * gigi.h (others_decl, all_others_decl): New decls representing the
30597 new Others_Value and All_Others_Value objects.
30598 (struct attrib): Rename "arg" component as "args", since GCC expects a
30599 list of arguments in there.
30601 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
30602 corresponding objects exported by a-exexpr, instead of hardcoded dummy
30605 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
30606 others_decl and all_others_decl instead of hardcoded dummy addresses
30607 to represent "others" and "all others" choices, which is cleaner and
30608 more flexible with respect to the possible eh pointer encoding policies.
30610 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
30611 (process_attributes): Account for the naming change of the "args"
30612 attribute list entry component.
30614 * decl.c (build_attr_list): Rename into prepend_attributes to allow
30615 cumulating attributes for different entities into a single list.
30616 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
30617 attributes for the current entity and propagate first subtype
30618 attributes to other subtypes.
30619 <E_Procedure>: Attribute arguments are attr->args and not
30620 attr->arg any more.
30621 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
30622 argument provided, as this is what GCC expects. Use NULL_TREE instead
30625 2004-11-18 Robert Dewar <dewar@adacore.com>
30627 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

30655 (Add_RAS_Dereference_TSS): Add comments.
30656 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
30657 is not referenced yet because it will be used by the PolyORB DSA
30659 (Insert_Partition_Check): Remove fossile code.
30660 (First_RCI_Subprogram_Id): Document this constant.
30661 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
30663 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
30664 replaced with calls to Get_Library_Unit_Name_String. Previously there
30665 were several instances of the same code in different locations in the
30666 compiler; this checkin completes the replacement of all of these
30667 instances with calls to a common subprogram.
30668 Minor reformatting.
30670 * sem_dist.adb: Remove comment noting that RPC receiver generation
30671 should be disabled for RACWs that implement RASs.

30696 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
30697 (Expand_Pragma_Psect_Object): New procedure
30698 These procedures contain the revised and cleaned up processing for
30699 these two pragmas. This processing was formerly in Sem_Prag, but
30700 is more appropriately moved here. The cleanup involves making sure
30701 that the pragmas are properly attached to the tree, and that no
30702 nodes are improperly shared.
30704 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
30705 pragmas to Exp_Prag, which is more appropriate.
30706 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
30707 check for duplicates Remove use of Is_Psected flag, no longer needed.
30708 Use new Make_String_Literal function with string.
30710 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30711 that are functions return universal values, that have to be converted
30712 to the context type.
30713 Use new Make_String_Literal function with string.
30714 (Get_Stream_Convert_Pragma): New function, replaces the use of
30715 Get_Rep_Pragma, which had to be kludged to work in this case.
30717 * freeze.adb: Use new Has_Rep_Pragma function
30719 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30720 function with string.
30721 Use new Has_Rep_Pragma function.

30747 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30748 discriminant of a constrained subtype, analyze the copy of the
30749 corresponding constraint, because in some cases it may be only
30750 partially analyzed.
30751 Removes long-lived ??? comments.
30753 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30754 handled controlled or secondary-stack expressions within the
30755 iteration_scheme of a loop.
30757 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30758 bounds that may contain functions calls, to prevent memory leaks when
30759 the bound contains a call to a function that uses the secondary stack.
30760 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30761 generate temporaries for loop bounds that might contain function calls
30762 that require secondary stack and/or finalization actions.
30764 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30765 selected component and the selector is overloadable (not just a
30766 function) treat as function call, Analyze_Call will disambiguate if
30768 (Analyze_Selected_Component): Do not generate an actual subtype for the
30769 selected component if expansion is disabled. The actual subtype is only
30770 needed for constraint checks.
30771 (Analyze_Allocator): If restriction No_Streams is set, then do
30772 not permit objects to be declared of a stream type, or of a
30773 composite type containing a stream.
30775 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30776 No_Streams no longer prohibits with'ing this package.
30778 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30779 discriminants, but the parent base has unknown discriminants, there is
30780 no discriminant constraint to inherit. Such a discrepancy can arise
30781 when the actual for a formal type with unknown discriminants is a
30782 similar private type whose full view has discriminants.
30783 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30784 do not permit objects to be declared of a stream type, or of a
30785 composite type containing a stream.
30787 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30789 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30790 protected operations.
30792 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30793 generated name, it complicates decoding in gdb and hinders debugging
30794 of protected operations.

30796 flag for the protected entry barrier function.
30797 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

30812 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30813 type of the object with the packed array type, set the Analyzed flag
30814 on the object if it is an entity or simple indexed component, to avoid
30815 spurious type errors.

30837 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30838 for Detect_Blocking which is redundant with the check done within the
30839 procedure Protected_Single_Entry_Call.
30840 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30841 Detect_Blocking which is redundant with the check done within the
30842 procedure Protected_Single_Entry_Call.
30844 2004-11-18 Vincent Celier <celier@adacore.com>
30846 * makegpr.adb (Compile): Put the compiling switches (in package
30847 Compiler and on the command line) immediately after "-c", instead of
30848 at the end of the command line invocation of the compiler, when
30849 compiling a non-Ada file.
30850 (Build_Global_Archive): When there is no need to rebuild the archive,
30851 set Global_Archive_Exists, so that the archive is passed to the linker
30854 2004-11-18 Robert Dewar <dewar@adacore.com>
30855 Sergey Rybin <rybin@adacore.com>
30858 Remove extra paren check from list of checks for redundant constructs
30859 Add documentation of new -gnatyx style check (check extra parens)
30860 Remove paragraph about gnatelim debug options.
30862 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30863 objects rather than forbidding dependencies on the package Ada.Streams.
30865 * sinfo.ads: Add ??? note that we should document pragmas passed to
30868 * g-expect.ads: Fix a few typos in the comments.
30870 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30872 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30875 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30877 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30879 2004-11-07 Andreas Schwab <schwab@suse.de>
30881 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30883 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30886 * Makefile.in (darwin): Set soext to .dylib.
30888 2004-10-26 Vincent Celier <celier@gnat.com>
30889 Thomas Quinot <quinot@act-europe.fr>
30891 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30892 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30893 there is no use of GNAT.Sockets.Constants.
30894 Remove remaining pragma Import for C_Write
30895 Remove C_Read and C_Write from internal implementation unit
30896 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30897 the read and write functions from the system runtime library is fine
30898 on UNIX but won't work under Windows).
30900 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30901 (Check_Selector): Use C_Recv instead of C_Read.
30902 Selectors are the GNAT.Sockets abstraction to perform a select()
30903 call on a set of descriptors. To allow abortion of an ongoing
30904 select operation, some data is written to a dedicated socket that
30905 is always monitored.
30906 Under Windows, the write and read library functions cannot operate
30907 on sockets, so we need to use send and recv instead, which is portable
30908 across all supported platforms.
30910 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30911 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30912 (using the read and write functions from the system runtime library is
30913 fine on UNIX but won't work under Windows).
30915 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30917 * mlib-tgt-darwin.adb: New file.
30919 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30920 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30921 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30922 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30925 * Makefile.in: Add support for building shared libraries under Darwin.
30926 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30927 the low level EH init subprogram to be called from __gnat_initialize.
30929 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30930 indicates which options to pass to the archive indexer.
30932 * mlib-utl.adb: Add support for calling ranlib with additional
30933 options. This is needed for instance under Mac OS X.
30934 (Ranlib_Options): New global variable, used to store the potential
30935 options to pass to ranlib.
30936 (Ar): Use Ranlib_Options when spawning ranlib.
30937 (Initialize): Set the value of ranlib option.
30939 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30941 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30942 instead of 8K, to reflect the real potential needs for stack-checking
30945 2004-10-26 Pascal Obry <obry@gnat.com>
30947 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30949 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30950 Windows only the initial thread stack size can be set so it is good to
30951 start we a low stack size.
30952 The OS will adjust the size as needed.
30954 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30955 Nicolas Setton <setton@act-europe.fr>
30957 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30958 "__unix__" instead of "unix".
30959 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30960 sections were just mistakenly ignored. The former is
30961 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30962 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30963 of hpux. This prevents an unwanted definition of the symbol
30964 convert_addresses in adaint.o.
30966 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30968 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30969 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30971 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30973 * a-filico.ads, a-filico.adb: fix incorrect header.
30975 2004-10-26 Javier Miranda <miranda@gnat.com>
30977 * a-ststio.ads: Fix typo in identifier
30979 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30981 * sem_ch4.adb: Minor reformatting.
30983 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30985 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30986 enabled, check the result of unary and binary operations when the
30987 expression is the right-hand side of an assignment.
30989 2004-10-26 Vincent Celier <celier@gnat.com>
30991 * clean.adb (Delete): Do not output warnings when in quiet output and
30992 not in verbose mode.
30993 (Force_Deletions): New Boolean flag, defaulted to False
30994 (Delete): Only delete a file if it is writable, and when
30995 Force_Deletions is True.
30996 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30997 (Usage): Line for new switch -f
30998 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
31001 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
31003 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
31004 JM type only if its size matches that of the wrapper. When a size is
31005 prescribed and the field is not aliased, remove the wrapper of a JM
31006 type only if the size is not greater than that of the packed array.
31007 (gnat_to_gnu_entity): Change the extension of packed array wrappers
31010 2004-10-26 Geert Bosch <bosch@gnat.com>
31012 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
31013 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
31014 (Pred): Implement in terms of Succ.
31016 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31018 * exp_aggr.adb (Safe_Component): An aggregate component that is an
31019 unchecked conversion is safe for in-place use if the expression of the
31020 conversion is safe.
31021 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
31022 be expandable in place even if the aggregate does not come from source.
31023 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
31024 designated object of an allocator in place, rather than building it
31025 first on the stack. The previous scheme forces a full copy of the array,
31026 and may be altogether unsusable if the size of the array is too large
31027 for stack allocation.
31029 2004-10-26 Robert Dewar <dewar@gnat.com>
31031 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
31032 compares if the component is atomic.
31034 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
31035 array assignment if the component type is atomic.
31037 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31038 Eric Botcazou <ebotcazou@act-europe.fr>
31040 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
31041 is aliased and is a by_reference type, do not pass by copy.
31042 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
31043 detect whether the call is in the right side of an assignment or
31044 the expression of an object declaration. Recurse on component
31045 association within aggregates.
31046 Call it in the condition that determines whether the temporary is
31047 necessary for correct stack-checking.
31049 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
31051 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
31052 RACW_Type, used in the PolyORB version.
31053 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
31054 version and the GARLIC version.
31056 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
31057 Rename RCI_Info to RCI_Locator for better consistency between the
31058 GARLIC and PolyORB versions of the distributed systems annex.
31059 (DSA_Implementation_Name): This enumeration lists the possible
31060 implementations of the Partition Communication Subsystem for the
31061 Distributed Systems Annex (DSA). The three available implementations
31062 are the dummy stub implementation (No_DSA), and two versions based on
31063 two different distribution runtime libraries: GARLIC and PolyORB. Both
31064 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
31066 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
31069 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
31070 between the GARLIC and PolyORB versions of the distributed systems
31072 Remove RE_Unbounded_Reclaim_Pool since it is unused.
31074 2004-10-26 Gary Dismukes <dismukes@gnat.com>
31076 * gnat1drv.adb: Suppress calling the back end when
31077 Frontend_Layout_On_Target is true.
31079 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
31081 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
31082 Set_Read_Only): New subprograms.
31083 These new routines allow the user to set or unset the Owner execute
31084 and Owner write permission flags on a file.
31086 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
31087 GNAT.OS_Lib.Set_Executable instead of rolling our own.
31089 2004-10-26 Matthew Gingell <gingell@gnat.com>
31091 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
31093 2004-10-26 Pascal Obry <obry@gnat.com>
31095 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
31096 memory before the faulting page we properly test the process read
31097 access for this address using appropriate Win32 routine.
31098 (HPUX sections): guard with "__hpux__" instead of "hpux".
31100 2004-10-26 Robert Dewar <dewar@gnat.com>
31102 * lib-xref.adb (Generate_Reference): Don't complain about reference to
31103 entry parameter if pragma Unreferenced set, since we do not properly
31104 handle the case of multiple parameters.
31106 2004-10-26 Vincent Celier <celier@gnat.com>
31108 * prj-env.adb: (Contains_ALI_Files): New Boolean function
31109 (Ada_Objects_Path.Add): For a library project, add to the object path
31110 the library directory only if there is no object directory or if the
31111 library directory contains ALI files.
31112 (Set_Ada_Paths.Add.Recursive_Add): Ditto
31114 2004-10-26 Vincent Celier <celier@gnat.com>
31116 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
31117 extension of library projects.
31119 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
31120 path defaults to ".:<prefix>/lib/gnat".
31121 (Parse): For an extending all project, allow direct import of a project
31122 that is virtually extended.
31124 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
31125 the specified name is directly imported, return its ID. Otherwise, if
31126 an extension of this project is imported, return the ID of the
31129 2004-10-26 Robert Dewar <dewar@gnat.com>
31131 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
31132 (Sub3): New procedure, used by Scaled_Divide
31133 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
31134 correct more than one instance of failure to propagate carries
31136 (Double_Divide): Handle overflow case of largest negative number
31137 divided by minus one.
31139 * s-arit64.ads (Double_Divide): Document that overflow can occur in
31140 the case of a quotient value out of range.
31143 2004-10-26 Robert Dewar <dewar@gnat.com>
31145 * s-bitops.adb (Bit_Eq): Remove redundant check.
31147 * s-bitops.ads: Minor comment updates
31148 Change some occurrences of Address to System.Address
31150 * s-carsi8.ads: Fix minor cut-and-paste error in comments
31152 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31154 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
31155 accessibility check to prefix that is a protected operation.
31157 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31159 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
31160 empty, post message on stub.
31162 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31163 Javier Miranda <miranda@gnat.com>
31165 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
31166 current instance appears within a unit that is directly in the context
31168 Used to determine whether the body of the instance should be analyzed
31169 immediately after its spec, to make its subprogram bodies available
31170 for front-end inlining.
31171 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
31172 constraint is not allowed on the component type (AARM 12.5.3(3))
31174 2004-10-26 Cyrille Comar <comar@act-europe.fr>
31176 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
31177 'Storage_Pool): enhance, document & limit detection of non-sharable
31180 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
31182 * s-pooglo.ads: Add more documentation now that this pool is properly
31185 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31187 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
31188 or protected type with discriminants, do not constrain the
31189 corresponding record type if the subtype declaration has no
31190 discriminant constraints. This can be the case in source code, or in
31191 the subtype declaration created to rename an actual type within an
31194 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31196 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
31197 different kind of stub (possibly wrong name for file), do not check
31199 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
31200 includes call to some function that returns an unconstrained type, do
31203 2004-10-26 Ed Schonberg <schonberg@gnat.com>
31205 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
31206 appear in the code for the main unit. Dependencies among units in the
31207 context of the main unit are established when those other units are
31208 compiled. Otherwise spurious elaboration constraints can generate
31209 incorrect elaboration circularities.
31211 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
31212 Ed Schonberg <schonberg@gnat.com>
31214 * sem_util.adb (Is_Aliased_View): Defend against the case where this
31215 subprogram is called with a parameter that is not an object name. This
31216 situation arises for some cases of illegal code, which is diagnosed
31217 later, and in this case it is wrong to call Is_Aliased, as that might
31218 cause a compiler crash.
31219 (Explain_Limited_Type): Refine previous fix to include
31220 inherited components of derived types, to provide complete information.
31222 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
31223 is the prival for a protected object.
31224 It is necessary to mark this entity as a variable, in addition to
31225 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
31226 modified to avoid checking the Aliased flag on entities that are not
31227 objects. (Checking that flag for non-objects is erroneous and could
31228 lead to a compiler crash).
31230 2004-10-26 Robert Dewar <dewar@gnat.com>
31232 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
31233 X_Frac = 0.5, then we know that the number X must be positive.
31234 (Succ): Remove the same redundant test, and also fix the primary test
31235 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
31237 (Decompose): Add fuller comments to spec
31239 2004-10-26 Pascal Obry <obry@gnat.com>
31241 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
31242 validity (process must have read access). Set to 0 in all other cases.
31243 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
31244 violation on Win32.
31245 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
31246 segmentation violation.
31248 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
31250 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
31251 whose type is a constructed subtype of an aliased object with an
31252 unconstrained nominal subtype, convert the actual to the constructed
31253 subtype before taking its address.
31255 2004-10-26 Vincent Celier <celier@gnat.com>
31257 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
31258 (Is_Path_Name_Case_Sensitive): New function
31260 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
31261 (Base_Name, Simple_Name, Current_Directory, Compose,
31262 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
31265 2004-10-26 Cyrille Comar <comar@act-europe.fr>
31266 Vasiliy Fofanov <fofanov@act-europe.fr>
31267 Vincent Celier <celier@gnat.com>
31269 * gnat_ugn.texi: Generalize "finding memory problems" section into a
31270 "memory management issues" section and document some of the useful
31271 memory pools provided as part of the GNAT library.
31272 Remove "virtual" from declaration of A::method2 in
31273 the simple example of Ada/C++ mixed system.
31274 Library Projects may be virtually extended: their virtual extensions
31275 are not Library Projects.
31276 Added section on extending project hierarchies.
31278 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
31280 * adaint.c (__gnat_get_libraries_from_registry): Cast value
31282 (__gnat_portable_spawn): Remove const.
31284 * mingw32.h (MAXPATHLEN): Check for previous definition.
31286 2004-10-17 Matthias Klose <doko@debian.org>
31288 * gnatvsn.ads: Set gnat library version to 4.0.
31290 2004-10-05 Vincent Celier <celier@gnat.com>
31292 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
31294 2004-10-04 Laurent Guerby <laurent@guerby.net>
31297 * Makefile.in: Define and use RANLIB_FLAGS.
31299 2004-10-04 Pascal Obry <obry@gnat.com>
31301 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
31302 other x86 platforms).
31304 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
31306 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
31307 in general and triggers stack alignment adjustment for thread entry
31308 points on targets where this is necessary.
31310 2004-10-04 Bernard Banner <banner@gnat.com>
31313 * Makefile.in: Add section for powerpc linux
31314 Add variant i-vxwork-x86.ads
31316 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
31318 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
31320 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
31321 table registration calls when need be. Ensures no reference to the crt
31322 ctors symbol are issued in the SJLJ case, which avoids possible
31323 undefined symbol errors in the case of modules to be statically linked
31326 2004-10-04 Javier Miranda <miranda@gnat.com>
31328 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
31329 in-line the code corresponding to subprogram Analyze_Actuals. In
31330 addition, analyze the actuals only in case of subprogram call.
31332 2004-10-04 Ed Falis <falis@gnat.com>
31334 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
31336 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
31338 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
31339 in the documentation.
31341 2004-10-04 Robert Dewar <dewar@gnat.com>
31343 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
31345 (Analyze_Block_Statement): Add circuitry to detect following dead code
31346 (Check_Unreachable_Code): Handle case of block exit
31348 2004-10-04 Robert Dewar <dewar@gnat.com>

31351 (XMatchD): Avoid warning for Logic_Error call
31353 2004-10-04 Robert Dewar <dewar@gnat.com>
31355 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
31356 consider expressions buried within a procedure actual to be an actual.
31357 This caused some blowups with uses of packed slices within a procedure
31360 2004-10-04 Robert Dewar <dewar@gnat.com>
31362 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
31363 longer need to be initialized to zero.
31364 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
31365 initialized to zero.
31367 * checks.adb (Expr_Known_Valid): Packed arrays are now always
31368 considered valid, even if the representation is modular. That's correct
31369 now that we no longer initialize packed modular arrays to zero.
31371 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
31372 suffixes. These are now documented as the only cases in which the
31373 debugger ignores outer records.
31374 Previously, the spec allowed arbitrary suffixes for this purpose.
31375 Change name of LJM to JM for packed array pad records
31376 Create separate section on packed array handling, and add a whole new
31377 set of comments to this section describing the situation with packed
31378 modular types and justification requirements depending on endianness.
31380 2004-10-04 Robert Dewar <dewar@gnat.com>
31382 * a-except.adb: Add a comment for last change
31384 * einfo.ads: Minor spelling correction in comment
31386 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
31388 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

31395 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
31396 Inline_Always when in Configurable_Run_Time mode.
31398 * sem_prag.adb (Process_Convention): If entity is an inherited
31399 subprogram, apply convention to parent subprogram if in same scope.
31400 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
31401 when in Configurable_Run_Time mode.
31403 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31405 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of

31410 * sem_ch12.adb (Check_Generic_Actuals): New predicate
31411 Denotes_Previous_Actual, to handle properly the case of a private
31412 actual that is also the component type of a subsequent array actual.
31413 The visibility status of the first actual is not affected when the
31414 second is installed.
31415 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
31416 make fully recursive the treatment of formals of packages declared
31418 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
31419 the above on exit from an instantiation.
31420 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
31421 current instantiation which is now complete.
31422 (Analyze_Package_Instantiation): No instantiated body is needed if the
31423 main unit is generic. Efficient, and avoid anomalies when a instance
31424 appears in a package accessed through rtsfind.
31426 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31428 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
31429 do not generate a declaration for a temporary if the call is part of a
31430 library-level instantiation.
31432 2004-10-04 Ed Schonberg <schonberg@gnat.com>
31434 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
31435 searching for a limited component to flag.
31437 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
31438 expansion of Input, to account for the fact that the implicit call
31439 generated by the attribute reference must freeze the user-defined
31440 stream subprogram. This is only relevant to 'Input, because it can
31441 appear in an object declaration, prior to the body of the subprogram.
31443 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
31444 expansion can proceed and further errors uncovered.
31445 (Minor clean up): Fix cases of using | instead of \ for continuation
31448 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31450 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
31452 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
31453 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
31454 Use gcc_assert and gcc_unreachable.
31456 * decl.c (gnat_to_gnu_entity, case object): Check and process a
31457 specified alignment before validating size.
31458 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
31459 stripped-down declaration for the type of the inner field when making
31462 * utils.c (finish_record_type): Do not compute the size in units
31463 incrementally. Instead compute it once for the rep clause case.
31464 Use gcc_assert and gcc_unreachable.
31466 2004-10-04 Vincent Celier <celier@gnat.com>
31468 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
31470 (Is_Valid_Path_Name): Take '/' as a directory separator.
31472 2004-10-04 Vincent Celier <celier@gnat.com>
31474 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
31475 (Extended_Project) only if Extended_Project is defined, to avoid
31477 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
31479 (Parse_Single_Project): Ditto.
31481 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
31482 Add_To_Project_Path for virtual projects.
31484 2004-10-04 Vincent Celier <celier@gnat.com>
31486 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

31490 parameter Options_2.
31492 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
31493 Build_Dynamic_Library with an empty Options_2.
31495 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
31498 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
31499 directory separator, if any.
31500 (Gprmake): Do not allow mains on the command line for library projects.
31501 Do not attempt to link when the project is a library project.
31502 (Library_Opts): New table to store Library_Options.
31503 (Build_Library): If Library_Options is specified, pass these options
31504 when building a shared library.
31506 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31508 * s-tposen.adb (Service_Entry): The object must be always unlocked at
31509 the end of this procedure now that the unlock operation was inserted
31512 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
31514 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
31515 corresponding to the Preallocated_Stacks flags in System.
31516 (Get_Target_Parameters): Including the processing for

31528 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
31529 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
31530 used to signal whether the compiler creates the required stacks and
31531 descriptors for the different tasks (when True) or it is done by the
31532 underlying operating system at run time (when False).
31533 It is initially set to False in all targets.
31535 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
31536 if it is supported by the target.
31537 (Make_Task_Create_Call): Pass the stack address if it has been
31538 previously created. Otherwise pass a Null_Address.
31540 * snames.adb: Add _stack.

31543 statically allocated task stacks.
31545 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
31546 Stack_Address argument.
31547 Check that its value is equal to Null_Address because this target does
31548 not support the static stack allocation.
31550 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31552 * usage.adb: Change "pragma inline" to "pragma Inline" in information

31557 * exp_dist.adb: Split declaration of asynchronous flag out of
31558 Add_RACW_Read_Attribute.
31559 Minor reformatting for better alignment with PolyORB version.
31560 Store the entity for the asynchronous flag of an RACW, rather than the
31561 expression, in the asynchronous flags table. This will allow this flag
31562 to be used in other subprograms beside Add_RACW_Read_Attribute.
31564 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
31566 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

31570 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
31571 sockets constant MSG_NOSIGNAL (Linux-specific).
31572 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
31573 all Send operations.
31574 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
31575 from trigerring SIGPIPE.
31576 Rename components to avoid clash with Ada 2005 possible reserved
31578 (Check_Selector): When the select system call returns with an error
31579 condition, propagate Socket_Error to the caller.
31581 2004-10-01 Jan Hubicka <jh@suse.cz>
31583 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
31585 2004-09-23 Robert Dewar <dewar@gnat.com>

31589 instead do this at freeze time (we won't do it if there is an address
31591 Change "pragma inline" to "pragma Inline" in information and error
31593 Minor reformatting.
31595 * freeze.adb (Check_Address_Clause): Remove previous change, not the
31596 right way of doing things after all.
31597 (Freeze_Entity): For object, set Is_Public for imported entities
31598 unless there is an address clause present.
31600 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
31602 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
31603 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
31604 ensures proper handling of types with rep clauses, which might have
31605 their TYPE_SIZE set already.
31607 2004-09-21 Robert Dewar <dewar@gnat.com>
31609 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
31610 packed array types in both little- and big-endian cases. This change
31611 ensures that we no longer count on the unused bits being initialized
31612 for such types (and in particular ensures that equality testing will
31613 only read the relevant bits).
31614 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31615 These changes mean that we no longer need to initialize small packed
31617 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
31618 optimization to an LJM field as to its parent field.
31620 * ada-tree.h, trans.c, utils.c, utils2.c:
31621 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
31623 2004-09-20 Jan Hubicka <jh@suse.cz>
31625 * utils.c (gnat_finalize): Remove.
31626 (end_subprog_body): Directly call cgraph_finalize_function;
31627 do not lower the nested functions.
31629 2004-09-20 Robert Dewar <dewar@gnat.com>
31632 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
31633 if an address clause is present, since that means that the Import
31636 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
31638 * 5tsystem.ads: Removed, no longer used.
31640 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

31643 * ada-tree.def: Use tree_code_class enumeration constants
31644 instead of code letters.

31662 an existing directory.
31663 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
31664 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
31665 Convert the result to File_Size.
31667 * prj.ads: (Project_Error): New exception
31669 * prj-attr.adb: Except in procedure Initialize, Fail comes from
31670 Prj.Com, not from Osint.
31671 (Attrs, Package_Attributes): Tables moved to private part of spec
31672 (Add_Attribute, Add_Unknown_Package): Moved to new child package
31674 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
31675 Prj.Project_Error after call to Fail.
31676 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
31677 Fail. Check that package name is not already in use.
31679 * prj-attr.ads: Comment updates to indicate that all subprograms may be
31680 used by tools, not only by the project manager, and to indicate that
31681 exception Prj.Prj_Error may be raised in case of problem.
31682 (Add_Unknown_Package, Add_Attribute): Moved to new child package
31684 (Attrs, Package_Attributes): Table instantiations moved from the body to
31685 the private part to be accessible from Prj.Attr.PM body.

31688 from new package Prj.Attr.PM.
31689 (Parse_Attribute_Declaration): Call Add_Attribute from new package
31692 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
31694 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
31695 instead of Elaboration_Checks).
31697 * a-calend.adb: Minor reformatting
31699 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

31757 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31758 Common_ATCB record. It contains the dynamic level of protected action
31759 nesting for each task. It is needed for checking whether potentially
31760 blocking operations are called from protected operations.

31798 contains the required machinery for handling that.
31800 * sem_util.ads: Change comment associated to procedure
31801 Check_Potentially_Blocking_Operation.
31802 This procedure does not insert a call for raising the exception because
31803 that is currently done by the run time.
31805 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31807 * init.c: Add the global variable __gl_detect_blocking that indicates
31808 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31809 making the pragma available at run time.
31810 (__gnat_set_globals): Pass and update the detect_blocking parameter.

31840 Update API in placeholder implemetation of s-parint to reflect changes
31841 in distribution runtime library.
31843 * sem_ch3.adb (Expand_Derived_Record): Rename to
31844 Expand_Record_Extension.
31846 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31847 primitive operations of potentially distributed object types that have
31848 non-controlling anonymous access formals.
31850 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31852 New implementation of expansion for remote access-to-subprogram types,
31853 based on the RACW infrastructure.
31854 This version of sem_dist is compatible with PolyORB/DSA as well as
31857 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31858 Asynchrronous that applies to a remote access-to-subprogram type, mark
31859 the underlying RACW type as asynchronous.
31861 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31862 __gnat_using_gnu_linker to 1.
31864 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31865 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

31871 * exp_ch3.adb (Expand_Derived_Record): Rename to
31872 Expand_Record_Extension.
31873 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31874 a component declaration must remain attached at that point in the
31875 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31876 It is therefore necessary to take a copy of the expression when building
31877 the corresponding assignment statement in the init proc.
31878 As a side effect, in the case of a derived record type, we now see the
31879 original expression, without any rewriting that could have occurred
31880 during expansion of the ancestor type's init proc, and we do not need
31881 to go back to Original_Node.

31891 subprogram. The proxy object is used as the designated object
31892 for RAS values on the same partition (unless All_Calls_Remote applies).
31893 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31894 System.Partition_Interface.Get_Unique_Remote_Pointer.
31895 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31896 Renamed from Add_RAS_*_Attribute.
31897 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31899 New implementation of expansion for remote access-to-subprogram types,
31900 based on the RACW infrastructure.
31902 * exp_dist.ads (Copy_Specification): Update comment to note that this
31903 function can copy the specification from either a subprogram
31904 specification or an access-to-subprogram type definition.
31906 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31908 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31909 in an instance, between an explicit subprogram an one inherited from a
31910 type derived from an actual.
31912 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31913 add a polling call if the subprogram is to be inlined by the back-end,
31914 to avoid repeated calls with multiple inlinings.
31916 * checks.adb (Apply_Alignment_Check): If the expression in the address
31917 clause is a call whose name is not a static entity (e.g. a dispatching
31918 call), treat as dynamic.

31922 * g-trasym.ads: Minor reformatting
31924 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31968 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31969 of variable length temporaries for function return now that the

32021 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
32022 packed indexed component where array is an IN OUT formal. This
32023 generated garbage code previously.

32045 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
32046 pragma Debug as an if statement with a constant condition, for
32047 consistent treatment of entity references contained within the
32048 enclosed procedure call.

32084 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
32085 target names rewrite to fix regressions with recent version of

32139 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
32140 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
32141 option and not mdll anymore. Update comment.
32143 2004-08-16 Pascal Obry <obry@gnat.com>
32145 * bld.adb (Put_Include_Project): Properly handle directory separators
32148 2004-08-16 Ed Schonberg <schonberg@gnat.com>

32161 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
32163 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
32164 for a global aliased object with a variable size and an unconstrained
32165 nominal subtype, pretend there is no initializer if the one we have is
32166 incomplete, and avoid referencing an inexistant component in there. The
32167 part we have will be rebuilt anyway and the reference may confuse
32168 further operations.

32190 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
32191 unit, this is an attempt to inline a construct that is not available in
32192 the current restricted mode, so abort rather than trying to continue.
32194 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
32195 discriminants that rename those of the parent, recover names of
32196 original discriminants for the constraint on the full view of the
32198 (Complete_Private_Subtype): Do not create a subtype declaration if the
32199 subtype is an itype.
32201 * gnat_rm.texi: Added section on implementation of discriminated
32202 records with default values for discriminants.
32204 2004-08-13 Ed Schonberg <schonberg@gnat.com>

32224 new specification and test explicitly for non-zero return value.
32226 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
32227 returning C.int, to avoid using a derived boolean type.
32229 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

32257 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
32258 ignore overflows on low and high bounds of an index to also account for
32259 differences in signedness between sizetype and gnu_index_subtype.
32260 These are as legitimate as the ones caused by a lower TYPE_PRECISION
32263 2004-08-09 Robert Dewar <dewar@gnat.com>
32265 * s-solita.ads, s-solita.adb: Minor reformatting
32267 * gnat_rm.texi: Add documentation for pragma Profile (Restricted)
32268 Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new

32271 run time constraint checks.
32273 * vms_conv.ads: Minor reformatting
32275 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup

32280 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
32281 pointer (cleanup and necessary for following change).
32282 Define Mark_Id as record containing address of secondary stack, that way
32283 Release does not need to find the stack again, decreasing the number of
32284 calls to Self and improving efficiency.

34819 Merge from tree-ssa-20020619-branch.
34821 * config-lang.in (boot_language, build_by_default): Set

34887 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
34888 overriding, use the operation of the parent unconditionally.
34890 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
34891 operation when either operand is a literal, to avoid further
34894 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

36176 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
36177 complete assignment subtree which is now unnecessary, as the expansion
36178 of inlined call has been improved to preserve a consistent assignment
36179 tree. Note_Possible_Modification must be called only
36180 after checks have been applied, or else unnecessary checks will
36183 * sem_util.adb (Note_Possible_Modification): Reorganise the handling

36441 * osint.adb (Executable_Prefix): Set Exec_Name to the current
36442 executable name when not initialized. Otherwise, use its current value.
36444 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
36445 initialize it to another executable name than the current one. This
36446 allows to configure paths for an executable name (gnatmake) different
36447 from the current one (gnatdist).
36449 2004-03-29 Ed Schonberg <schonberg@gnat.com>
36451 * exp_ch6.adb (Expand_Call): A call to a function declared in the
36452 current unit cannot be inlined if it appears in the body of a withed
36453 unit, to avoid order of elaboration problems in gigi.
36455 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
36456 information for protected (wrapper) operation as well, to simplify gdb
36459 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
36460 protected body, indicate that the entity for the generated spec comes
36461 from source, to ensure that references are properly generated for it.

36496 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
36498 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
36499 attribute reference does not denote a subtype, it can be any
36500 expression that has a classwide type, potentially after an implicit
36501 dereference. In particular, the prefix can be a view conversion for
36502 a classwide type (for which Is_Object_Reference holds), but it can
36503 also be a value conversion for an access-to-classwide type. In the
36504 latter case, there is an implicit dereference, and the original node
36505 for the prefix does not verify Is_Object_Reference.
36507 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
36508 conversion of a discriminant-dependent component of a mutable object
36511 2004-03-25 Ed Schonberg <schonberg@gnat.com>
36513 * freeze.adb (Freeze_Entity): When an inherited subprogram is
36514 inherited, has convention C, and has unconstrained array parameters,
36515 place the corresponding warning on the derived type declaration rather
36516 than the original subprogram.

36523 determine whether to generate an implicit or explicit reference to
36524 the renamed entity.

36527 subprogram renaming comes from a defaulted formal subprogram in an
36530 2004-03-25 Gary Dismukes <dismukes@gnat.com>
36532 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
36533 value expressions to ensure that calls within a component definition
36534 will be checked (since those are evaluated during the record type's

36586 declaration for a child subprogram body that acts as a spec, indicate
36587 that the entity in the declaration needs debugging information.
36589 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
36590 full view if the subtype is created for a constrained record component;
36591 gigi has enough information to construct the record, and there is no
36592 place in the tree for the declaration.
36594 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
36595 serial number for the dummy body that is built for analysis, to avoid
36596 inconsistencies in the generation of internal names when compiling

36632 * ada-tree.h: Update copyright notice.
36633 Minor reformatting.
36635 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
36637 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
36638 as regular exception objects and not as mere integers representing the
36639 condition code. The latter approach required some dynamics to mask off
36640 severity bits, which did not fit well into the GCC table based model.
36641 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
36642 exception data objects. We don't it and it would conflict with the other
36643 external symbol we have to generate for such exceptions.
36645 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
36646 the special code for VMS exceptions, since these are now represented
36647 as regular exceptions objects.

36689 * init.c [VxWorks]: Do not fix the stack size for the environment task.
36690 When needed (stack checking) the stack size is retrieved
36691 from the VxWorks kernel.
36693 * Makefile.in: Flag -nostdinc is required when building the run time
36694 for avoiding looking for files in the base compiler.
36695 Add the VxWorks specific version of the package body for
36696 System.Stack_checking.Operations (5zstchop.adb).
36698 * Make-lang.in: Add the object file for
36699 System.Stack_Checking.Operations.

36707 checking from this package to package System.Stack_Checking.Operations.
36708 This way, stack checking operations are only linked in the final

36723 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
36724 the procedures Add_To_Path_File.
36725 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
36726 making sure that each directory is present only once and, for object
36727 dirs, when a directory already present is added, the duplicate is

36941 explicit dereference.
36942 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36943 of non-packed slices, since the dereference action generated by

36946 analyze and resolve the rewritten explicit dereference so it is seen
36948 (Insert_Dereference_Action): This procedure is now called only for the

38333 * opt.ads: New parameter Default_Secondary_Stack_Size (GNATBIND)
38334 New switch Sec_Stack_Used (GNAT, GNATBIND)
38335 Make Default_Secondary_Stack_Size a variable instead of a constant,
38336 so that it can be modified by the new -Dnnn bind switch.
38338 * rtsfind.adb (Load_Fail): Give full error message in configurable
38339 run-time mode if all_errors mode is set. This was not done in the case
38340 of a file not found, which was an oversight.
38341 Note if secondary stack unit is used by compiler.
38343 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
38344 ineffective elaborate all pragmas on non-visible packages (this
38345 happened when a renamed subprogram was called). Now the elaborate all
38346 always goes on the package containing the renaming rather than the one
38347 containing the renamed subprogram.
38349 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
38350 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
38352 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
38353 has an Etype that references an E_String_Literal.
38354 (Eval_String_Literal): Avoid assumption that N_String_Literal node
38355 always references an E_String_Literal_Subtype entity. This may not
38356 be true in the future.
38358 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
38361 * sem_res.adb (Resolve): Specialize msg for function name used in proc
38364 2004-01-05 Ed Falis <falis@gnat.com>
38366 * g-debuti.adb: Replaced direct boolean operator with short-circuit
38369 2004-01-05 Vincent Celier <celier@gnat.com>
38371 * bld.adb: Minor comment updates
38372 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
38375 * make.adb (Gnatmake): Special process for files to compile/check when
38376 -B is specified. Fail when there are only foreign mains in attribute
38377 Main of the project file and -B is not specified. Do not skip bind/link
38378 steps when -B is specified.
38380 * makeusg.adb: Document new switch -B
38382 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
38384 * switch-m.adb: (Scan_Make_Switches): Process -B switch
38386 * vms_data.ads: Add new GNAT PRETTY qualifier

38398 has size that overflows.
38400 2004-01-05 Gary Dismukes <dismukes@gnat.com>
38402 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
38403 -gnatwa warning on static condition.
38405 2004-01-05 Doug Rupp <rupp@gnat.com>
38407 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
38409 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
38411 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
38412 all attributes, including read-only attribute.

38417 library naming scheme.
38419 * mlib-prj.adb (Build_Library): Generate different names for the static
38420 or dynamic version of the GNAT runtime. This is needed to support the
38421 new shared library naming scheme.
38422 (Process_Binder_File): Add detection of shared library in binder file
38423 based on the new naming scheme.
38425 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
38426 scheme for the shared runtime libraries.
38429 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
38431 (install-gnatlib): Do not create symlinks for shared libraries.
38432 (gnatlib-shared-default): Idem.
38433 (gnatlib-shared-dual-win32): New target. Not used for now as the
38434 auto-import feature does not support arrays/records.
38435 (gnatlib-shared-win32): Do not create copy for the shared libraries.
38436 (gnatlib-shared-vms): Fix shared runtime libraries names.
38438 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
38439 dependent runtime shared library name.
38441 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
38443 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
38446 2004-01-05 Ed Schonberg <schonberg@gnat.com>
38448 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
38449 protected objects when allocator has a subtype indication, not a
38450 qualified expression. Note that qualified expressions may have to be
38451 checked when limited aggregates are implemented.
38453 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
38454 pure, emit warning.
38455 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
38456 subprogram is imported, remove warning.
38458 2004-01-05 Geert Bosch <bosch@gnat.com>
38460 * s-poosiz.adb: Update copyright notice.
38461 (Allocate): Use Task_Lock to protect against concurrent access.
38462 (Deallocate): Likewise.

38496 Ada.Exceptions.Last_Chance_Handler.
38498 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
38500 * cstand.adb (Create_Standard): Change the way how the declaration of
38501 the Duration type is created (making it the same way as it is for all
38502 the other standard types).
38504 2003-12-17 Robert Dewar <dewar@gnat.com>
38506 * s-crtl.ads: Fix header format
38507 Change Pure to Preelaborate
38509 2003-12-17 Ed Schonberg <schonberg@gnat.com>
38511 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
38512 the expression type only if it is declared in the current unit.
38514 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
38515 are universal and already analyzed, as can occur in constrained
38516 subcomponents that depend on discriminants, when one constraint is a
38519 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
38520 type Any_Fixed is legal as the argument of a conversion, if only one
38521 fixed-point type is in context.
38523 2003-12-17 GNAT Script <nobody@gnat.com>

38532 2003-12-15 Vincent Celier <celier@gnat.com>
38534 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
38535 (Gnatchop): Do not set failure status when reporting the number of
38538 2003-12-15 Doug Rupp <rupp@gnat.com>
38540 * s-ctrl.ads: New file.
38542 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).

38562 2003-12-11 Ed Falis <falis@gnat.com>
38564 * 5zinit.adb: Clean up.
38566 * 5zintman.adb (Notify_Exception): replaced case statement with a call
38567 to __gnat_map_signal, imported from init.c to support
38568 signal -> exception mappings that depend on the vxWorks version.
38571 Created and exported __gnat_map_signal to support signal -> exception
38572 mapping that is dependent on the VxWorks version.
38573 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
38575 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

38587 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
38589 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
38591 * sinfo.ads: Fix inconsistent example code in comment.
38593 2003-12-11 Robert Dewar <dewar@gnat.com>
38595 * a-tiinau.adb: Add a couple of comments
38597 * sem_ch3.adb: Minor reformatting
38600 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
38601 Minor reformatting throughout
38603 2003-12-11 Ed Schonberg <schonberg@gnat.com>
38605 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
38606 bounds of a loop, create a separate block in order to generate proper
38607 cleanup actions to prevent memory leaks.
38609 * sem_res.adb (Resolve_Call): After a call to
38610 Establish_Transient_Scope, the call may be rewritten and relocated, in
38611 which case no further processing is needed.
38613 * sem_util.adb: (Wrong_Type): Refine previous fix.

38623 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
38626 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
38629 2003-12-08 Robert Dewar <dewar@gnat.com>
38631 * 7sintman.adb: Minor reformatting
38633 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
38634 standard linker options to get standard libraries linked. We now plan
38635 to provide dummy versions of these libraries to match the appropriate
38636 configurable run-time (e.g. if a library is not needed at all, provide
38637 a dummy empty library).
38639 * targparm.ads: Configurable_Run_Time mode no longer affects linker
38640 options (-L parameters and standard libraries). What we plan to do is
38641 to provide dummy libraries where the libraries are not required.
38643 * gnatbind.adb: Minor comment improvement
38645 2003-12-08 Javier Miranda <miranda@gnat.com>
38647 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
38648 aggregate in the parent. Otherwise constants with limited aggregates
38649 are not supported. Add new formal to pass the component type (Ctype).
38650 It is required to call the corresponding IP subprogram in case of
38651 default initialized components.
38652 (Gen_Assign): In case of default-initialized component, generate a
38653 call to the IP subprogram associated with the component.
38654 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
38655 of aggregate with default initialized components.
38656 (Has_Default_Init_Comps): Improve implementation to recursively check
38657 all the present expressions.
38659 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
38660 to indicate that the initialization call corresponds to a
38661 default-initialized component of an aggregate.
38662 In case of default initialized aggregate with tasks this parameter is
38663 used to generate a null string (this is just a workaround that must be
38664 improved later). In case of discriminants, this parameter is used to
38665 generate a selected component node that gives access to the discriminant
38668 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
38669 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
38670 allocated aggregates with default-initialized components.
38672 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
38673 the box notation is used in positional aggregates.
38675 2003-12-08 Samuel Tardieu <tardieu@act-europe.fr>

38690 (Parse): New Boolean parameter Store_Comments, defaulted to False.
38691 Set the scanner to return ends of line and comments as tokens, if
38692 Store_Comments is True.
38693 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
38694 comments are associated with these nodes. Store the node IDs in the
38696 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
38698 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
38699 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
38700 current project. Call Tree.Restore afterwards. Set the various nodes
38701 for comment storage (Next_End, End_Of_Line, Previous_Line,
38704 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
38705 defaulted to False.
38707 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
38708 to False. When Truncated is True, truncate the string, never go to the
38710 (Write_End_Of_Line_Comment): New procedure
38711 (Print): Process comments for nodes N_With_Clause,
38712 N_Package_Declaration, N_String_Type_Declaration,
38713 N_Attribute_Declaration, N_Typed_Variable_Declaration,
38714 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
38715 Process nodes N_Comment.
38717 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
38718 without comments and there are some comments, set the flag
38719 Unkept_Comments to True.
38720 (Scan): If there are comments, set the flag Unkept_Comments to True and
38721 clear the comments.
38722 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
38723 (Next_End_Nodes: New table
38724 (Comment_Zones_Of): New function
38725 (Scan): New procedure; moved from Prj. Accumulate comments in the

38740 (Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
38741 (Set_Next_Comment): New procedure
38742 (Default_Project_Node): Associate comment before if the node can store

38746 (Comment_Id): New global variable
38748 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
38749 defaulted to False.
38750 (Scan): Store position of start of comment. If comments are tokens, set
38751 Comment_Id and set Token to Tok_Comment when scanning a comment.
38752 (Set_Comment_As_Token): New procedure
38754 * sinput-p.adb: Update Copyright notice
38755 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
38756 that no longer exists.
38758 2003-12-08 Javier Miranda <miranda@gnat.com>
38760 * sem_aggr.adb: Add dependence on Exp_Tss package
38761 Correct typo in comment
38762 (Resolve_Aggregate): In case of array aggregates set the estimated
38763 type of the aggregate before calling resolve. This is needed to know
38764 the name of the corresponding IP in case of limited array aggregates.
38765 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
38766 in case of default initialized array components.
38768 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
38769 types. Required to give support to limited aggregates in generic
38772 2003-12-08 Ed Schonberg <schonberg@gnat.com>
38774 * sem_ch3.adb (Check_Initialization): For legality purposes, an
38775 inlined body functions like an instantiation.
38776 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
38777 until bounds are analyzed, to diagnose premature use of type.
38779 * sem_util.adb (Wrong_Type): Improve error message when the type of
38780 the expression is used prematurely.
38782 2003-12-08 GNAT Script <nobody@gnat.com>
38784 * Make-lang.in: Makefile automatically updated
38786 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
38788 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
38789 they are automatically generated by Make-lang.in and cause nothing but
38790 maintenance troubles.
38792 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
38794 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

38803 Update copyright notice when appropriate.
38805 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
38808 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
38809 to ensure that the kernel fills in the interrupted context structure
38810 before calling a signal handler, which is necessary to be able to
38811 unwind past it. Update the copyright notice.
38813 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
38815 * a-elchha.ads: New file.
38817 * a-elchha.adb: New default last chance handler. Contents taken from
38818 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
38820 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
38821 is moved to a-elchha.adb to provide a target-independent default last
38824 * Makefile.rtl: Add a-elchha.o
38826 * Make-lang.in (GNAT_ADA_OBJS, GNATBIND_OBJS): Add a-elchha.o.

38830 * exp_ch6.adb (Expand_Call): If the subprogram is inlined and is
38831 declared in an instance, do not inline the call if the instance is not
38832 frozen yet, to prevent order of elaboration problems.
38834 * sem_prag.adb: Add comments for previous fix.
38836 2003-12-05 Samuel Tardieu <tardieu@act-europe.fr>
38838 * g-table.adb: Use the right variable in Set_Item.
38839 Update copyright notice.

38847 * switch-c.adb (Scan_Front_End_Switches): Remove processing of
38848 -nostdlib. Not needed here after all.
38850 2003-12-03 Thomas Quinot <quinot@act-europe.fr>
38853 * adaint.h, adaint.c, g-os_lib.ads:
38854 Do not assume that the offset argument to lseek(2) is a 32 bit integer,

42440 lieu of explicit sizeof/sizeof.
42442 2002-02-28 Neil Booth <neil@daikokuya.demon.co.uk>
42444 * misc.c (copy_lang_decl): Remove.
42446 2002-02-27 Zack Weinberg <zack@codesourcery.com>
42448 * misc.c: Delete traditional-mode-related code copied from the
42449 C front end but not used, or used only to permit the compiler
42452 2002-02-07 Richard Henderson <rth@redhat.com>
42454 * adaint.c (__gnat_to_gm_time): First arg is int, not time_t.
42455 * adaint.h (__gnat_to_gm_time): Update prototype.
42457 2002-01-30 Richard Henderson <rth@redhat.com>
42459 * trans.c (tree_transform) [N_Loop_Statement]: Use
42460 expand_exit_loop_top_cond.
42462 2001-12-23 Richard Henderson <rth@redhat.com>

42471 2001-12-23 Florian Weimer <fw@deneb.enyo.de>
42473 * gnat-style.texi (Declarations and Types): Remove ancient style
42474 rule which was mandated by code generation issues.
42476 * gnat-style.texi (header): Add @dircategory, @direntry.
42477 (title page): Remove date.
42478 (general) Add @./@: where approriate, and two spaces after the
42479 full stop at the end of a sentence. Use @samp markup when
42480 referring concrete lexical entities (keywords, attribute names
42481 etc.), and @syntax for ARM grammar elements. Use @r for English
42482 text in comments. Use @emph for emphasis. Change "if-statements"
42483 etc. to "if statements" (without @samp). Break long lines. Make
42484 casing of section names consistent.
42485 (Identifiers): Use @samp markup for variable names.
42486 (Comments): Use @samp markup for comment characters. Line-end
42487 comments may follow any Ada code, not just statements. Fix
42488 misspelling of "Integer" as "integer".
42489 (Loop statements): Do not use variable name "I", use "J".
42490 (Subprogram Declarations): Document alignment.

42494 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
42496 * make.adb (Add_Switch): Make Generic_Position a procedure. The
42497 function approach did not work well because of a side effect (the
42498 function call could reallocate the table which was being indexed
42499 using its result). Fixes ada/4851.
42501 2001-12-19 Robert Dewar <dewar@gnat.com>

42533 -gnatec/-gnatem processing)
42535 2001-12-19 Olivier Hainque <hainque@gnat.com>
42537 * raise.c (__gnat_eh_personality): Exception handling personality
42538 routine for Ada. Still in rough state, inspired from the C++ version
42539 and still containing a bunch of debugging artifacts.
42540 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
42541 inspired from the C++ library.
42543 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
42544 exception handling integration.
42546 2001-12-19 Arnaud Charlet <charlet@gnat.com>

42866 2001-12-17 Laurent Pautet <pautet@gnat.com>
42869 Fix comment of Shutdown_Socket and Close_Socket. These functions
42870 should not fail silently because if they are called twice, this
42871 probably means that there is a race condition in the user program.
42872 Anyway, this behaviour is consistent with the rest of this unit.
42873 When an error occurs, an exception is raised with the error message
42874 as exception message.

44263 * sinput-p.adb (Load_Project_File): rename Source_Checksum to
44264 Source_CRC in S initialization.
44266 * sinput.adb (Source_Checksum): renamed to Source_CRC.
44268 * sinput.ads (Source_Checksum): renamed to Source_CRC.
44269 Update comments for the CRC.
44271 * types.adb (Hex): Use lowercase for the letter part.
44273 * types.ads (Get_Hex_String): Returns the hexadecimal representation
44274 for a word. This is currently used only for CRC. In previous version,
44275 the checksum was using a representation with all letter being
44276 upper-case. With the new implementation (using CRC) we do not remove
44277 the 32th bit of the CRC, so we can have an upper-case starting letter
44278 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
44279 It is ambigous since the CRC was optional and could be followed by
44280 options like EB, EE. So now this routines uses lower-case letter for
44281 the hexadecimal representation. Strange enough only lower case letters
44282 where checked in Scan_ALI (even if this was not a possible case).
