1732 gnu_expr_alt_type parameter. Convert the expression to it instead
1733 of changing its type in place.

1796 correct accessibility levels. In the "when others" case, retrieve the
1797 access level of the Etype of Prev rather than Prev_Orig, because the
1798 original exression has not always been analyzed.

1873 it is properly decorated for ASIS use.
1875 2008-08-01 Gary Dismukes <dismukes@adacore.com>
1877 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1878 Orig_Prev to Prev in the case where the actual is N_Function_Call or
1879 N_Identifier. This was interfering with other cases that are rewritten
1880 as N_Identifier, such as allocators, resulting in passing of the wrong
1881 accessibility level, and based on testing this code is apparently no
1882 longer needed at all.
1884 2008-08-01 Ed Schonberg <schonberg@adacore.com>
1886 * sem_ch4.adb (Analyze_One_Call): Handle complex overloading of a

1983 * cstreams.c (__gnat_full_name): RTSS applications cannot ask for the

2200 * prj-part.adb, prj-part.ads, prj.adb, prj.ads, prj-env.adb:

2204 Minimum_Linker_Options as they are no longer set.
2205 Remove function There_Are_Ada_Sources from package Prj and move code

4017 (P_Access_Definition): Change the error message when parsing "access
4018 all" in Ada 95 mode. The message no longer forces the user to recompile
4019 in 05 mode only to discover that anonymous access types are not allowed

4038 (Set_Categorization_From_Scope): Do not set In_Remote_Types unless in
4039 the visible part of the spec of a remote types unit.
4040 (Validate_Remote_Access_Object_Type_Declaration):
4041 New local subprogram Is_Valid_Remote_Object_Type, replaces
4042 Is_Recursively_Limited_Private.
4043 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4044 non-controlling formals (and the return type, even though this is not
4045 explicit in the standard) must support external streaming.
4046 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4047 as above for of RAS types and RCI subprograms. (The return type is not

4052 * sem_util.ads, sem_util.adb
4053 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4054 Is_Remote_Call_Interface to identify RACW types in a stable and
4055 consistent way. We used to rely in this predicate on the privateness of
4056 the designated type and its ancestors, but depending on the currently
4057 visible private parts, this caused false negatives. We now uniformly
4058 rely on checks made at the point where the RACW type is declared.

4070 constants declared in scopes other than packages since they can be
4071 completed with pragma Import.
4072 Add missing escaping of all-caps word 'CPP' in error messages.
4073 (Build_Discriminated_Subtype): Do not inherit representation clauses
4074 from parent type if subtype already carries them, because they are
4075 inherited earlier during derivation and already include those that may
4076 come from a partial view.
4078 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4079 Check the declarations of a subprogram body for proper deferred

4113 (Add_One_Interp): Ignore any interpretation that is a primitive
4114 operation of an RACW stub type (these primitives are only executed
4115 through dispatching, never through static calls).
4116 (Collect_Interps): When only one interpretation has been found, set N's
4117 Entity and Etype to that interpretation, otherwise Entity and Etype may
4118 still refer to an interpretation that was ignored by Add_One_Interp,
4119 in which case would end up with being marked as not overloaded but with
4120 an Entity attribute not pointing to its (unique) correct interpretation.
4122 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4125 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4135 (Print_Itype): Do not modify the sloc of the component type of a
4136 (packed) array itype, because it is an unrelated type whose source
4137 location is independent of the point of creation of the itype itself.

4180 compilation of this file under 64 bits platforms.

8448 formal of a generic subprogram. find candidate interpretations by
8449 scanning the list of generic formal declarations.:
8450 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8451 type from a limited_with_clause, and the full view is available, use it
8452 for subsequent semantic checks.

8487 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8488 Timed_Entry_Call): Analyze the triggering statement as the first step of
8489 the processing. If this is a dispatching select, postpone the analysis

8492 replicated some of the select statements. In case the Expander is
8493 disabled, perform regular analysis.
8494 (Check_Triggering_Statement): New routine.
8495 (Analyze_Requeue): Exclude any interpretations that are not entries when
8496 checking overloaded names in a requeue. Also test type conformance for
8497 matching interpretations rather than requiring subtype conformance at

9091 Add support for parsing multiple array index types info, or
9092 multiple inherited interfaces info. This information cannot be stored
9093 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9109 Dismukes). After this patch there is no need to perform any
9110 additional management on these nodes in Expand_Interface_Actuals.
9112 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9113 that handles use of 'Access and 'Unchecked_Access applied to
9114 actuals covering interface types. Such code is now
9115 centralized in Expand_N_Attribute_Reference.

9159 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9160 used by VxWorks targets to have access to task-specific data and be
9161 able to extract the stack boundaries for stack checking.

9205 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9206 association for an access component, add an association with null as
9207 the expression. Remove testing for array subtypes and the setting in
9208 that case of Ctyp to the array component type, which prevented proper
9209 inclusion of an association for null-initialized arrays. Collapse
9210 condition that tests for array subtypes into just a test of
9211 Is_Partially_Initialized_Type (which already covers arrays anyway).

9228 * sem_ch4.adb: Minor code and comment reformatting.
9229 (Analyze_Allocator): When the designated type of an unconstrained
9230 allocator is a record with unknown discriminants or an array with

9419 s-taprop-solaris.adb, s-taprop-vms.adb, s-taprop-mingw.adb,
9420 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9422 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9424 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9425 function which can be called by the debugger to interrupt the tasks of
9426 an Ada application asynchronously, as needed on VxWorks.
9427 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9429 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
9430 renamed from Stop_All_Tasks. Update comments.
9431 (Stop_All_tasks): New function declaration.
9433 2007-09-26 Olivier Hainque <hainque@adacore.com>
9435 * adaint.c (if defined (__Lynx__)): Wrap #def/#undef VMOS_DEV around
9436 #include <utime.h> and #define GCC_RESOURCE_H before
9437 #include <sys/wait.h>.
9438 Add more protections in __gnat_translate_vms.
9440 * expect.c (if defined (__Lynx__)): #define GCC_RESOURCE_H before

9446 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9448 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9451 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9453 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9456 * sem_dist.ads: Minor comment fix

9460 2007-09-26 Javier Miranda <miranda@adacore.com>
9461 Eric Botcazou <ebotcazou@adacore.com>
9464 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9465 indirection added to the HT_Link component of the TSD. This is required
9466 to statically allocate the TSD.
9469 Minor reordering of the declarations in the private part. Required to
9470 add a level of indirection to the contents of the TSD component HT_Link.
9471 This is required to statically allocate the TSD.
9473 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9474 Is_Statically_Allocated set from constant objects.
9475 Do not make exported constants created by the compiler volatile.
9476 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9479 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9480 before returning them.
9482 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9483 public part of the package.
9484 (Make_DT): Move HT_Link component out of the TSD record. For this
9485 purpose Make_DT now declares a separate object that stores the
9486 HT_Link value, and initializes the TSD component with the address
9487 of this new object. The addition of this level of indirection is
9488 required to statically allocate the TSD because the TSD cannot
9489 have variable components.
9490 (Expand_Interface_Conversion): Improve the expanded code.
9491 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9493 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9494 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9495 if we are building static dispatch tables then we must not generate
9496 extra code to register the primitive because the dispatch table will
9497 be built at the end of the library package; otherwise we notify that
9498 we cannot build the static dispatch table.
9500 2007-09-26 Robert Dewar <dewar@adacore.com>
9502 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address
9505 * sem_ch13.ads, sem_ch13.adb: Improve warnings for address overlays
9506 (Analyze_Record_Representation_Clause): Suppress junk warning for

9517 for thunks associated with interface types.
9519 * einfo.ads: Improve documentatation of Is_Internal
9520 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9521 associated with interface types.
9522 Extensive comment fixes regarding flags that appear in all entities. The
9523 documentation is now consistent for all such flags (there were a number
9524 of errors in the documentation in this regard).
9526 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9528 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9529 of these procedures are passed a function call that already has
9530 build-in-place actuals (testing new flag
9531 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9532 the case where processing continues.
9533 (Expand_Call): If the call is generated from a thunk body then we
9534 propagate the extra actuals associated with the accessibility
9535 level of the access type actuals.
9537 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9538 of each extra formal of a protected operation to reference the
9539 corresponding extra formal of the subprogram denoted by the
9540 operation's Protected_Body_Subprogram.
9542 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9543 N_Function_Call nodes.
9545 2007-09-26 Robert Dewar <dewar@adacore.com>
9547 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9549 * debug.adb: Add d.s flag.
9551 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9553 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9554 debug variable so that it won't be initialized when pragma
9555 Initialize_Scalars is in effect.
9557 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9559 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9560 initialization of a full view. This is moved to
9561 Analyze_Package_Specification.
9563 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9564 preelaborable initialization of a full view in entity loop.
9565 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9566 its child units are use-visible only if they are visible child units.
9568 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9569 whether an expression can be used within a type declaration that
9570 requires preelaborable init.
9571 (Check_Components): Replace inline code that does partial checking for
9572 preelaborable default expressions with call to
9573 Is_Preelaborable_Expression.
9574 (Has_Preelaborable_Initialization): In the case of a generic actual
9575 subtype, (that is, Is_Generic_Actual is True), return the result of
9576 applying Has_Preelaborable_Initialization to the generic actual's base
9579 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9581 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9582 call to Jan_1_Day _Of_Week to optimize its performance.
9583 (Is_Leap): Move the routine to the scope of Week_In_Year.
9584 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9585 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9586 avoids calling Time_Of and Split, thus making it more efficent.
9587 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9589 * g-calend.ads (Week_In_Year): Change comment to reflect new
9592 2007-09-26 Emmanuel Briot <briot@adacore.com>
9594 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9595 Command_Line): New types
9596 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9597 support for defining how switches can be grouped on a command line (as
9598 is the case for -gnatw... for GNAT), and how simple switches can be
9599 used as aliases for more complex switches (-gnatwa is same as
9601 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9602 (Start, Current_*): New subprograms
9603 Added support for parsing an array of strings in addition to the real
9605 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9606 be moved from the body to the private part of the spec.
9607 (*): All subprograms now have an extra parameter with default value to
9608 specify which parser should be used. For backward compatibility, it
9609 defaults to parsing the command line of the application. They were also
9610 modified to properly handle cases where each of the argument does not
9611 start at index 1 (which is always true for Ada.Command_Line, but not
9612 when processing any Argument_List).
9613 (Free): New subprogram
9614 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9615 Argument): New subprograms
9616 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9617 special characters like ':', '=',... are now handled in a single place,
9618 which makes the code more extensible eventually.
9619 (Getopt, Full_Switch): When the switch was returned as part of the
9620 special character '*', make sure it is prepended by the switch character
9621 ('-' in general), so that the application knows whether "foo" or "-foo"
9622 was specified on the command line.
9624 2007-09-26 Florian Villoing <villoing@adacore.com>
9626 * g-dirope.adb (Remove_Dir): In case we are removing directories
9627 recursively, make sure that if an exception is raised during the
9628 processing, the current working directory is reset to its initial
9629 value before propagating the exception.
9631 2007-09-26 Vincent Celier <celier@adacore.com>
9633 * gnatbind.adb: If there are several ALI files specified and there is
9634 a main program to bind, the first ALI is expected to contain the main
9635 subprogram and the names of the binder generated files will be derived
9636 from the first ALI file name.
9637 (Gnatbind): Fix insertion character in invocation of Error_Msg
9639 2007-09-26 Vincent Celier <celier@adacore.com>
9641 * gnatcmd.adb (Check_Files): Do not include sources that have been
9642 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9644 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9646 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9647 information about each of its index types, following the type
9648 reference for its component type.
9650 2007-09-26 Vincent Celier <celier@adacore.com>
9652 * make.adb: (Kill): New procedure (__gnat_kill imported)

9659 sources, so that the correct paths will be found.
9661 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9663 2007-09-26 Vincent Celier <celier@adacore.com>
9665 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9667 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9668 Replace components Compiler_Min_Options and Binder_Min_Options with
9669 Compiler_Required_Switches and Binder_Required_Switches in record
9671 Remove components Default_Language and Config in Project_Tree_Data,
9674 * prj-attr.adb: New attributes Required_Switches (<language>) in
9675 packages Compiler and Binder.
9677 * prj-nmsc.adb: Major rewrite of the processing of configuration
9678 attributes for gprbuild. No impact on GNAT tools.
9680 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9681 process configuration attributes: this is done in Prj.Nmsc.Check.

9686 (Process): Implementation now uses the two new procedures
9688 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9689 from the project config, not the tree config that no longer exists.

9715 ancestor of the derived type, the operations are inherited from the
9716 primary dispatch table of the parent.
9717 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9718 when the context is an explicit type conversion.

10015 Thomas Quinot <quinot@adacore.com>
10017 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10018 create an abstract subprogram in the case of 'Input. For 'Output we now
10019 create a real spec/body when the type is abstract, since it can
10020 potentially be called.
10021 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10022 body for 'Output when the type is abstract (only the creation of the
10023 body for 'Input is excluded when the type is abstract).
10024 (Stream_Operation_OK): Add an additional condition in the return
10025 statement, so that False will be returned for TTS_Stream_Input if the
10026 associated tagged type is an abstract extension. Add comments for
10028 (Expand_N_Object_Declaration): For the case of a shared passive
10029 variable, insert init proc call only after the shared variable
10030 procedures have been processed, because the IP call needs to undergo
10031 shared passive variable reference expansion, which requires these
10032 procedures to be available (and elaborated).

10041 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
10042 given a box association, the type of the component is discriminated,
10043 and the value of the discriminant is the discriminant of the enclosing
10044 type, retrieve its value from the aggregate itself, where it must have
10047 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10048 to remove other spurious ambiguities on arithmetic operations involving
10049 literals and addresses, on systems where Address is a visible integer
10050 type, when the operator is called in functional notation.
10051 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10052 is legal when the types match, even if the operation is currently
10055 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10057 * sem_ch12.adb (Build_Local_Package): A formal package with no
10058 associations is legal if all formals have defaults. It is not
10059 equivalent to a formal declared with a box.
10061 2007-09-10 Sergey Rybin <rybin@adacore.com>

10089 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
10091 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
10092 which a constant renaming is treated as a normal object declaration.
10093 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
10094 the N_Indexed_Component case.
10095 <N_Indexed_Component>: Fall through to above case.

10176 (Is_Raised, Set_Is_Raised): Bodies of new routines.
10177 (Write_Entity_Flags): Write the status of flag Is_Raised.
10178 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10179 spurious ambiguities when integer literals appear in the context of an
10180 address type that is a visible integer type.
10182 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10183 exceptions never being raised.

10198 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10200 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10201 library-level package renaming, pass the declaration associated with
10202 the renaming's special debug variable to Qualify_Entity_Names to ensure
10203 that its encoded name is properly qualified.
10205 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10206 occurring in the list of entities to qualify, and do not attempt to
10207 traverse an entity list in that case. Variables associated with
10208 ` library-level package renamings can now occur in the table.

10232 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10233 concatenations of string literals into a single literal, in order to
10234 avoid very deep recursion in the front end, which was causing stack
10237 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10238 string, and the right operand is a string literal (the case of "" &
10239 "..."), optimize by avoiding copying the right operand -- just use the
10240 value of the right operand directly.
10242 * stringt.adb (Store_String_Chars): Optimize by growing the
10243 String_Chars table all at once, rather than appending characters one by
10245 (Write_String_Table_Entry): If the string to be printed is very long,
10246 just print the first few characters, followed by the length. Otherwise,
10247 doing "pn(n)" in the debugger can take an extremely long time.
10249 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10250 Store_String_Char with Store_String_Chars.

10265 have not been fully analyzed.
10267 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10269 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10270 flag, for effiency. It is called when analyzing arithmetic operators
10271 and also for actuals in calls that are universal_integers. The flag is
10272 set for the predefined type address, and for any type or subtype
10275 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10276 Universal_Integer, when the formal is a descendent of address and the
10277 call appears in user code.
10278 (Analyze_Selected_Component): if the prefix is a private extension, the
10279 tag component is visible.
10281 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

10320 gnatpp '--separate-stmt-name' option.
10321 Add new qualifier /USE_ON_NEW_LIN for the new gnatpp '--use-on-new-line'
10324 * gnat_ugn.texi: Add description for the new gnatpp
10325 '--separate-stmt-name' and '--use-on-new-line' options.
10327 2007-08-31 Ben Elliston <bje@au.ibm.com>
10329 * Makefile.in (LIBGNAT_TARGET_PAIRS): Use system-linux-ppc64.ads
10330 when compiling for powerpc64-*-linux.
10331 * system-linux-ppc64.ads: New file.
10333 2007-08-22 Krister Walfridsson <cato@df.lth.se>

10338 2007-08-16 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
10340 * misc.c (gnat_type_max_size): Constify.
10342 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10344 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10345 associated with Standard_Debug_Renaming_Type, to be used as the type of
10346 the special variables whose names provide debugger encodings for
10347 renaming declarations.
10349 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10350 (Set_Debug_Renaming_Link): Change to set Node25.
10351 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10352 (Write_Field25_Name): Add case for E_Variable to output
10353 "Debug_Renaming_Link".
10354 (Write_Field23_Name): Correct the output string for "Limited_View".
10356 * exp_dbug.adb: Add with and use of Tbuild.
10357 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10358 and literal with creation of a variable of type
10359 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10360 and the entity of the renaming declaration.
10361 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10362 part of the name of a variable that has a Debug_Renaming_Link.
10364 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10365 special type to be associated with variables that provide debugger
10366 encodings for renaming declarations.

10369 Ed Schonberg <schonberg@adacore.com>
10370 Javier Miranda <miranda@adacore.com>
10372 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10373 ancestor part given by an aggregate to test for an unchecked conversion,
10374 since this can occur in some cases when the ancestor part is a function
10375 call, and we don't want to fall into the recursive call to this
10376 procedure in that case.
10378 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10379 stream attributes on limited types to account for user-specified
10380 attributes as well as whether Input (resp. Output) becomes available
10381 due to Read (resp. Write) being available for the type. Change Boolean
10382 variable to the more accurate name
10383 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10384 double-"not" predicate at beginning of return statement to more
10385 understandable form.
10387 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10388 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10389 in a block statement and use that as the first statement of the
10390 expanded return rather than incorrectly using the handled sequence as
10391 the first statement.
10393 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10394 operation, generate an explicit freeze node for it rather than
10395 generating extra formals, to ensure that gigi has the proper order of
10396 elaboration for anonymous subtypes in the signature of the subprograms.
10397 (Build_In_Place_Formal): Move assertion to beginning of loop.
10398 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10399 applied to a function call (occurs for some cases of 'Input).

10401 applied to a function call (occurs for some cases of 'Input).
10403 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10404 2005, generate an extended return statement enclosing the result object
10407 * freeze.adb (Freeze_Record_Type): Extend the current management of
10408 components that are access type with an allocator as default value: add
10409 missing support to the use of qualified expressions of the
10410 allocator (which also cause freezing of the designated type!)
10411 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10412 dispatching operation, since extra formals may be needed by calls to
10413 build-in-place functions (such as stream 'Input).
10415 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10416 formals for 'Constrained and accessibility level in the case of a
10417 predefined dispatching operation.
10419 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10420 point, no need to find the parent node.
10422 2007-08-16 Javier Miranda <miranda@adacore.com>
10424 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10425 and entry barriers.
10427 2007-08-16 Javier Miranda <miranda@adacore.com>
10429 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10430 is not really required and can introduce regression with the debugger.
10431 The original problem is fixed with the patch written for checks.adb.
10433 2007-08-16 Thomas Quinot <quinot@adacore.com>
10435 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10436 Range_Check on Allocated_Table.
10438 2007-08-16 Vincent Celier <celier@adacore.com>
10440 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10441 Including_Non_Switch set to False.
10442 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10443 Including_Non_Switch set to False.
10445 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10446 parameter Including_Non_Switch, defaulted to True. When
10447 Including_Non_Switch is False, options that are not switches and
10448 appear as relative path are not converted to absolute paths.
10450 2007-08-16 Nicolas Roche <roche@adacore.com>
10452 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub
10455 * Make-lang.in: Update dependencies
10457 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10459 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10460 currently inspected is a selected component, retrieve the entity of
10462 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10463 from the immediate ancestor of Main_Unit_Entity.
10464 (Install_Limited_Withed_Unit): Do not install the limited view of
10465 package P if P is reachable through an ancestor chain from package C
10466 and C also has a with clause for P in its body.
10467 (Has_Limited_With_Clause): New routine.
10468 (Has_With_Clause): New routine.
10470 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10472 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10473 generic for an enclosing instance is a global reference, even though
10474 its scope is the enclosing instance.
10476 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10477 Javier Miranda <miranda@adacore.com>
10479 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10480 initialize a limited object.
10481 (Build_Derived_Record_Type): Add missing check of rules ARM 3.9.4
10483 Make sure Has_Complex_Representation is inherited by derived type.
10485 2007-08-16 Robert Dewar <dewar@adacore.com>
10487 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10490 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10492 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10493 implements an operation inherited from a progenitor interface, verify
10494 that they are subtype-conformant.
10496 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10497 Bob Duff <duff@adacore.com>
10498 Nicolas Setton <setton@adacore.com>
10500 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10501 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10502 the statement which is being resolved comes from a predefined library
10503 unit, all non-predefined library interpretations are skipped.
10504 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10505 but the "&" is user defined, give an error, because the folding would
10508 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10509 the parser has folded a long sequence of concatenations of string
10512 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10513 and "JMP_BUF" variables as artificial.
10514 (N_String_Literal): Do not use alloca for very long string literals. Use
10515 xmalloc/free instead. Otherwise the stack might overflow.
10517 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the
10520 2007-08-16 Vincent Celier <celier@adacore.com>
10522 * vms_conv.adb (Process_Argument): Ensure that project related options
10523 are not put in the -cargs section when using GNAT COMPILE.
10525 2007-08-16 Robert Dewar <dewar@adacore.com>
10527 * gnat_ugn.texi: Add note on preprocessing (output file not written)
10529 2007-08-16 Thomas Quinot <quinot@adacore.com>
10531 * a-tags.adb: Minor reformatting.
10533 2007-08-16 Bob Duff <duff@adacore.com>
10535 * sem_type.ads, sem_ch4.adb: Minor reformatting.
10537 2007-08-14 Thomas Quinot <quinot@adacore.com>
10539 * g-soccon-interix.ads, a-excpol-interix.adb, a-intnam-interix.ads,

10552 par-ch5.adb, par-ch10.adb, get_targ.adb, a-wtedit.adb, a-teioed.adb,
10553 s-osinte-solaris.adb, s-osinte-solaris.ads,
10554 s-osinte-freebsd.ads, s-osinte-freebsd.adb: Minor reformatting.
10556 * styleg.adb, styleg.ads, stylesw.adb, stylesw.ads: implement style
10557 switch -gnatyS. Enable -gnatyS in GNAT style check mode
10559 2007-08-14 Robert Dewar <dewar@adacore.com>
10560 Ed Schonberg <schonberg@adacore.com>
10562 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10563 Suppress unmodified in-out parameter warning in some cases
10564 This patch is a also fairly significant change to the way suppressible
10565 checks are handled.
10567 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10568 needed for access to concurrent record types generated by the expander.
10569 (Generate_Range_Check): When generating a temporary to capture the
10570 value of a conversion that requires a range check, set the type of the
10571 temporary before rewriting the node, so that the type is always
10572 properly placed for back-end use.
10573 (Apply_Float_Conversion_Check): Handle case where the conversion is
10575 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10576 for a protected type in order to examine its discriminants.
10578 2007-08-14 Robert Dewar <dewar@adacore.com>
10579 Gary Dismukes <dismukes@adacore.com>
10580 Ed Schonberg <schonberg@adacore.com>
10581 Thomas Quinot <quinot@adacore.com>
10583 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10584 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10585 tests optimized out.
10587 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10588 (Get_Allocator_Final_List): For the case of an anonymous access type
10589 that has a specified Associated_Final_Chain, do not go up to the
10591 (Expand_N_Type_Conversion): Test for the case of renamings of access
10592 parameters when deciding whether to apply a run-time accessibility
10594 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10595 aggregate code before allocator, and ahead of declaration for
10596 temporary, to prevent access before elaboration when the allocator is
10597 an actual for an access parameter.
10598 (Expand_N_Type_Conversion): On an access type conversion involving an
10599 access parameter, do not apply an accessibility check when the
10600 operand's original node was an attribute other than 'Access. We now
10601 create access conversions for the expansion of 'Unchecked_Access and
10602 'Unrestricted_Access in certain cases and clearly accessibility should
10603 not be checked for those.
10605 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10606 includes a type conversion of a packed component that has been expanded,
10607 recover the original expression for the object, and use this expression
10608 in the post-call assignment statement, so that the assignment is made
10609 to the object and not to a back-end temporary.
10610 (Freeze_Subprogram): In case of primitives of tagged types not defined
10611 at the library level force generation of code to register the primitive
10612 in the dispatch table. In addition some code reorganization has been
10613 done to leave the implementation clear.
10614 (Expand_Call): When expanding an inherited implicit conversion,
10615 preserve the type of the inherited function after the intrinsic
10616 operation has been expanded.
10618 * exp_ch2.ads, exp_ch2.adb
10619 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10620 of an entry formal appearing in an assignment statement does not assign
10622 (Expand_Current_Value): Instead of calling a routine to determine
10623 whether the prefix of an attribute reference should be optimized or
10624 not, prevent the optimization of such prefixes all together.
10626 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10627 component whose prefix is known to be of an access type is an implicit
10628 dereference and does not assign to the prefix.
10630 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10631 Robert Dewar <dewar@adacore.com>
10633 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10634 itype is visited, make an entry into table to link associated node and
10636 Add comments and correct harmless error in Build_NCT_Hash_Tables
10637 (Array_Aggr_Subtype): Associate each itype created for an index type to
10638 the corresponding range construct, and not to the aggregate itself. to
10639 maintain a one-to-one correspondence between itype and its associated
10640 node, to prevent errors when complex expression is copied.
10641 Fix mishandling of multiple levels of parens
10643 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10644 treatment of limited views uniform for all visible declarations in a
10645 limited_withed package.
10646 (New_Copy_Tree): If hash table is being used and itype is visited,
10647 make an entry into table to link associated node and new itype.
10648 (Resolve_Record_Aggregate): Do not add an others box association for a
10649 discriminated record component that has only discriminants, when there
10650 is a box association for the component itself.
10652 * par-ch4.adb: Fix mishandling of multiple levels of parens
10654 2007-08-14 Robert Dewar <dewar@adacore.com>
10656 * comperr.adb: Fix problem with suppressing warning messages from gigi
10658 * erroutc.ads, erroutc.adb, errout.ads,
10659 errout.adb (Write_Eol): Remove trailing spaces before writing the line
10660 (Write_Eol_Keep_Blanks): New procedure to write a line, including
10661 possible trailing spaces.
10662 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
10663 Fix problem with suppressing warning messages from back end
10664 Improve handling of deleted warnings
10667 Fix problem with suppressing warning messages from back end
10668 Handle setting of Static_Dispatch_Tables flag.
10671 Fix problem with suppressing warning messages from back end
10673 * exp_intr.adb: Improve handling of deleted warnings
10675 2007-08-14 Robert Dewar <dewar@adacore.com>
10677 * debug.adb: Improve -gnatdI to cover all cases of serialization
10678 Add documentation of dZ, d.t
10680 * sprint.ads, sprint.adb: Improve -gnatdI to cover all cases of
10682 (Sprint_Node_Actual): Generate new output associated with implicit

10687 Javier Miranda <miranda@adacore.com>
10688 Gary Dismukes <dismukes@adacore.com>
10690 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10691 to make treatment of limited views uniform for all visible declarations
10692 in a limited_withed package.
10693 Improve warnings for in out parameters
10694 (Set_Related_Interaface/Related_Interface): Allow the use of this
10695 attribute with constants.
10696 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10697 Warn on duplicate pragma Preelaborable_Initialialization
10699 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10700 generation of a freezing node to ensure proper management of null
10701 excluding access types in the backend.
10702 (Create_Extra_Formals): Test base type of the formal when checking for
10703 the need to add an extra accessibility-level formal. Pass the entity E
10704 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10705 originally being done in a couple of cases), to ensure that the
10706 Extra_Formals list gets set on the entity E when the first entity is
10708 (Conforming_Types): Add missing calls to Base_Type to the code that
10709 handles anonymous access types. This is required to handle the
10710 general case because Process_Formals builds internal subtype entities
10711 to handle null-excluding access types.
10712 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10713 functions that need it, even when not marked Requires_Overriding.
10714 Improve warnings for in out parameters
10715 (Analyze_Function_Return): Warn for disallowed null return
10716 Warn on return from procedure with unset out parameter
10717 Ensure consistent use of # in error messages
10718 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10719 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10720 the implicit conversion of the expression done for anonymous access
10721 types. This is required to generate the code of the null excluding
10722 check (if required).
10724 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10725 A formal parameter is never publicly referenceable outside of its body.
10726 (Check_References): For an unreferenced formal parameter in an accept
10727 statement, use the same warning circuitry as for subprogram formal
10729 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10730 Output_Unreferenced_Messages, containing the part of that routine that
10731 is now reused for entry formals as described above.
10732 (Goto_Spec_Entity): New function
10733 (Check_References): Do not give IN OUT warning for dispatching operation
10734 Improve warnings for in out parameters
10735 (Test_Ref): Check that the entity is not undefinite before calling
10736 Scope_Within, in order to avoid infinite loops.
10737 Warn on return from procedure with unset out parameter
10738 Improved warnings for unused variables

10742 Gary Dismukes <dismukes@adacore.com>
10744 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10745 (Expand_N_Attribute_Reference): Further unify the handling of the
10746 three forms of access attributes, using common code now for all three
10747 cases. Add a test for the case of applying an access attribute to
10748 an explicit dereference when the context is an access-to-interface
10749 type. In that case we need to apply the conversion to the prefix
10750 of the explicit dereference rather than the prefix of the attribute.
10751 (Attribute_Version, UET_Address): Set entity as internal to ensure
10752 proper dg output of implicit importation.
10753 (Expand_Access_To_Type): Removed.
10754 (Expand_N_Attribute_Reference): Merge the code from the three cases
10755 of access attributes, since the processing is largely identical for
10756 these cases. The substantive fix here is to process the case of a
10757 type name prefix (current instance case) before handling the case
10758 of interface prefixes.

10763 Robert Dewar <dewar@adacore.com>
10765 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10766 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10767 type that is an anonymous access to controlled object, establish
10768 an associated finalization chain to avoid corrupting the global
10769 finalization list when a dynamically allocated object designated
10770 by such a component is deallocated.
10771 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10772 functions that need it, even when not marked Requires_Overriding.
10773 (Initialize_Tag): Replace call to has_discriminants by call to
10774 Is_Variable_Size_Record in the circuitry that handles the
10775 initialization of secondary tags.
10776 (Is_Variable_Size_Record): New implementation.
10777 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10778 Suppress_Initialization pragma for a derived type.
10779 (Is_Variable_Size_Record): New subprogram.
10780 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10781 initial version of this routine and also fixes problems causing
10782 incomplete initialization of the table of interfaces.
10783 (Build_Init_Procedure): Improve the generation of code to initialize the
10784 the tag components of secondary dispatch tables.
10785 (Init_Secondary_Tags): New implementation that simplifies the previous
10786 version of this routine.

10839 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10840 output of implicit importation and exportation.
10841 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10842 first formal of the thunk is always associated with the controlling
10843 type. In addition perform the following code cleanup: remove formal
10844 Thunk_Alias which is no longer required, cleanup evaluation of the
10845 the controlling type, and update the documentation.
10846 Replace occurrence of Default_Prim_Op_Count by

10870 * exp_util.ads, exp_util.adb:
10871 This patch replaces a number of occurrences of explicit tests for N_Null
10872 with calls to Known_Null. This improves tracking of null values, since
10873 Known_Null also catches null constants, and variables currently known to
10874 be null, so we get better tracking.
10875 (Ensure_Defined): create an itype reference only in the scope of the
10877 (Side_Effect_Free): A selected component of an access type that
10878 denotes a component with a rep clause must be treated as not
10879 side-effect free, because if it is part of a linked structure its
10880 value may be affected by a renaming.
10881 (Expand_Subtype_From_Expr): For limited objects initialized with build
10882 in place function calls, do nothing; otherwise we prematurely introduce
10883 an N_Reference node in the expression initializing the object, which
10884 breaks the circuitry that detects and adds the additional arguments to
10885 the called function. Bug found working in the new patch for statically
10886 allocated dispatch tables.
10887 (Is_Library_Level_Tagged_Type): New subprogram.
10888 (Remove_Side_Effects): If the expression of an elementary type is an
10889 operator treat as a function call.
10890 (Make_Literal_Range): If the index type of the array is not integer, use
10891 attributes properly to compute the constraint on the resulting aggregate
10894 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10895 class-wide type whose base type is an incomplete private type, leave
10896 class-wide type unfrozen so that freeze nodes can be generated
10897 properly at a later point.
10898 (Freeze_Entity, array case): Handle case of pragma Pack and component
10899 size attributre clause for same array.

11527 (Set_Item): When the new item is an element of the currently allocated
11528 table passed by reference, save a copy on the stack if we're going

11545 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11546 derived type with interface progenitors use the analyzed formal as the
11547 parent of the actual, to create renamings for all the inherited
11548 operations in Derive_Subprograms.
11549 (Collect_Previous_Instances): new procedure within of
11550 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11551 unit being loaded, to ensure that the generation of global symbols is
11552 consistent in different compilation modes.
11553 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11554 takes progenitor types into account.
11555 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11556 traversing over the primitives of the formal and actual types to locate
11557 any abstract subprograms of the actual type that correspond to a
11558 nonabstract subprogram of the formal type's ancestor type(s), and issue
11559 an error if such is found.
11560 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11561 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11562 Remove bogus guard around calls to Inherit_Context.
11563 (Reset_Entity): If the entity is the selector of a selected component
11564 that denotes a named number, propagate constant-folding to the generic
11565 template only if the named number is global to the generic unit.

11567 a predefined or internal unit.
11569 2007-08-14 Ed Schonberg <schonberg@adacore.com>

11572 parameter to determine whether operation applies to the prefix.
11573 (Complete_Object_Operation): If actual has an access type and
11574 controlling formal is not an in_parameter, reject the actual if it is
11575 an access_to_constant type.
11576 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11577 type, the candidate operations are found in the scope of declaration of
11578 the type, because the type has no primitive subprograms.
11579 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11580 a private extension, only examine visible components before trying to
11581 analyze as a prefixed call.
11582 Change Entity_List to Type_To_Use, for better readability.
11583 (Has_Fixed_Op): Use base type when checking whether the type of an
11584 operator has a user-defined multiplication/division

11589 Ed Schonberg <schonberg@adacore.com>
11591 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11592 formal At_Any_Place indicating, when True, that we want to test for
11593 availability of the stream attribute at any place (as opposed to the
11594 current visibility context only).
11595 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11596 purpose of enforcing E.2.2(8) only if it is not available at any place.
11597 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11598 when checking the legality of an extension aggregate in a preelaborable
11599 package. Treat the literal null as a valid default expression in a
11600 component declaration for a type with preelaborable initialization.
11601 A limited interface is a legal progenitor for the designated type of a
11602 remote access to class-wide type.

11614 mark the full view as referenced, to prevent spurious warnings.
11615 (Find_Selected_Component, Has_Components): Handle properly non-limited
11616 views that are themselves incomplete types.
11617 Handle interfaces visible through limited-with clauses.
11618 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11619 subprogram generic actual for which we have generated a renaming.
11620 Warn when the renaming introduces a homonym of
11621 the renamed entity, and the renamed entity is directly visible.

11624 Hristian Kirtchev <kirtchev@adacore.com>
11626 * sem_res.adb (Resolve_Allocator): Propagate any coextensions that
11627 appear in the subtree to the current allocator if it is not a static
11629 (Resolve_Allocator): Perform cleanup if resolution has determined that
11630 the allocator is not a coextension.
11631 (Resolve): Skip an interpretation hidden by an abstract operator only
11632 when the type of the interpretation matches that of the context.
11633 (Resolve): When looping through all possible interpretations of a node,
11634 do not consider those that are hidden by abstract operators.
11635 (Resolve_Actuals): When verifying that an access to class-wide object
11636 is an actual for a controlling formal, ignore anonymous access to
11637 subprograms whose return type is an access to class_wide type.
11638 (Resolve_Slice): If the prefix of the slice is a selected component
11639 whose type depends on discriminants, build its actual subtype before
11640 applying range checks on the bounds of the slice.
11641 (Valid_Conversion): In an instance or inlined body, compare root types,
11642 to prevent anomalies between private and public views.
11643 (Resolve): Improve error message for ambiguous fixed multiplication
11644 expressions that involve universal_fixed multiplying operations.

11664 elabration statements, register the package with the name server
11665 at the beginning, not at the end, of the elaboration statements so
11666 that they can create remote access to subprogram values that designate
11667 remote subprograms from the package.

12815 Arnaud Charlet <charlet@adacore.com>
12817 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12818 applicable to types that have the With_Type flag set. Returns the
12819 non-limited view of the type, if available, otherwise the type itself.
12820 For class-wide types, there is no direct link in the tree, so we have
12821 to retrieve the class-wide type of the non-limited view of the Etype.
12822 New attributes Static_Initialization and Static_Elaboration_Desired.
12823 Remove the pragma Thread_Body, and the associated flag
12824 Is_Thread_Body in entities, and all related code.

12837 (Original_Access_Type): Remove, not needed.
12838 (Root_Type): Handle properly subtypes of class-wide-types.
12841 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12842 class-wide types visible through limited-with clauses.
12843 (Try_Primitive_Operation): When examining all primitive operations of a
12844 tagged type, do not consider subprograms labeled as hidden unless they
12845 belong to a private generic type with a tagged parent.
12846 (Try_Object_Operation): Extensive rewriting, to handle properly various
12847 overloading cases, when several ancestors may have class-wide operations
12848 that are possible candidates, and when the overloaded functions return
12849 array types and have defaulted parameters so that the call may be
12850 interpreted as an indexing.
12851 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12852 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12853 successive actuals before analyzing the call itself.
12854 (Try_Primitive_Operation): A primitive operation is compatible with the
12855 prefix if the prefix has a synchronized type and the type of the formal
12856 is its corresponding record, as can be the case when the primitive
12857 operation is declared outside of the body of the type.
12858 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12859 perform homonym traversal, looking for class-wide operation matches
12860 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12861 access parameters are now restricted to anonymous access types.
12862 (Mark_Allocator): An allocator with a discriminant association parent is
12864 (Try_One_Prefix_Interpretation): If the type of the object is
12865 incomplete, as can be happen when it is a limited view obtained through
12866 a limited_with_clause, the selected component is not part of a prefixed
12868 (Complete_Object_Operation): Diagnose properly an object that is not
12869 aliased when the corresponding controlling formal is an access
12871 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12872 ambiguous calls in prefixed notation, where two primitives differ only
12873 in that the controlling argument of one is an access parameter.
12875 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12876 whether a function that returns an unconstrained type can be inlined.
12877 (Process_Formals): Diagnose properly the illegal use of an incomplete
12878 type in the profile of an access_to_subprogram declaration.
12879 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12880 operations are attached to the corresponding record.
12881 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12882 When processing a primitive of a concurrent type which implements an
12883 interface change the type of all controlling formals to that of the
12884 corresponding record type.
12885 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12886 to determine the tagged type to which a primitive belongs.
12887 (Check_Conventions): Capture condition to ignore a primitive operation
12888 (which is shared between the loop in Check_Conventions and the one in
12889 Check_Convention) in a new local function Skip_Check.
12890 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12891 confusion with Check_Conventions' own Prim_Op local variable.
12892 (Create_Extra_Formals): Test for a tagged result type rather than a
12893 controlling result when determining whether to add a BIP_Alloc_Form
12894 formal and a BIP_Final_List formal to the function.
12895 (Check_Conformance); For parameters that are anonymous access types,
12896 subtype conformance requires that the not null and the constant
12897 indicators must match
12898 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12899 to retrieve the appropriate type when processing a concurrent type
12900 declared within a generic. Minor comment reformatting. Change invocation
12901 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12903 (Analyze_Subprogram_Body): If the return type of a function is an
12904 anonymous access to the limited view of a class-wide type, and the
12905 non-limited view of the type is available, update the type of the
12906 function so that code can be generated.
12907 (Process_Formals): In case of access-subtype itype whose designated
12908 type is also an itype (situation that happens now with access to
12909 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12910 attribute to avoid backend problems.
12911 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12912 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12913 anonymous types' designated types are same before testing
12914 Subtypes_Statically_Match.
12915 (Create_Extra_Formals): Test for a named access parameter that is a
12916 controlling formal as an additional condition for adding an
12917 accessibility level formal. This can occur in the subp type created for
12918 dispatching calls in Expand_Dispatching_Call, and allows calling
12919 Create_Extra_Formals from that procedure rather than special-casing the
12920 extra formals there.
12921 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12922 when the function has a controlling result.
12923 (Check_Returns): Add much more knowledge of the optimization of local
12924 raise statements to gotos, to retain proper warnings in this case.
12925 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12926 nodes when looking for last statement.
12928 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12929 class-wide types visible through limited with clauses.
12930 (Add_One_Interp): If the operands are anonymous access types, the
12931 predefined operator on universal_access is immediately visibles
12932 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12933 other anonymous access types.
12934 (Disambiguate): Take into account CIL convention.
12935 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.

12955 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12956 in extension aggregates.
12957 (Flatten): Other conditions being met, an aggregate is static if the
12958 low bound given by component associations is different from the low
12959 bound of the base index type.
12960 (Packed_Array_Aggregate_Handled): If the component type is itself a
12961 packed array or record, the front-end must expand into assignments.
12962 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12963 Init_Pr, instead of Ancestor_Is_Expression.
12964 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12965 coextension chain root, either generate a list controller or use the
12966 already existing one.
12967 (Static_Array_Aggregate): New procedure to construct a positional
12968 aggregate that can be handled by the backend, when all bounds and
12969 components are compile-time known constants.
12970 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12971 types covering interface types into assignments.
12972 (Replace_Type): move to Build_Record_Aggr_Code.
12973 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12974 interface type, convert to the definite type of the aggregate itself,
12975 so that needed components are visible.
12976 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12977 components and the context is an extended return statement do not
12978 create a transient block for it, to prevent premature finalization
12979 before the return is executed.
12980 (Gen_Assign): Do not generate a call to deep adjust routine if the
12981 component type is itself an array of controlled (sub)-components
12982 initialized with an inner aggregate.
12983 (Component_Check): New name for Static_Check. This name is now more
12984 appropriate, and documentation is added which was missing.
12985 (Component_Check): Add test for bit aligned component value
12986 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12987 Tagged_Comps, name is more appropriate given added function below.
12988 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12992 Robert Dewar <dewar@adacore.com>
12994 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12995 Terminated: Add unchecked type conversion from System.Address to
12996 System.Tasking.Task_Id when calling the predefined primitive
12998 Disable new Ada 05 accessibility check for JVM.NET targets, which
12999 cannot be implemented in a practical way.
13000 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13001 the sources always references the tag of the actual object. Therefore,
13002 if 'Tag is applied in the sources to class-wide interface objects we
13003 generate code that displaces "this" to reference the base of the object.
13004 (Expand_N_Attribute_Reference, case Size): Return specified size if
13005 known to front end.
13006 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13007 has code that displaces the pointer of the object to manage interface
13008 types. However this code must not be executed when the prefix is a
13009 subprogram. This bug caused the wrong expansion of the internally
13010 generated assignment that fills the dispatch table when the primitive
13011 is a function returning a class-wide interface type.
13012 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13013 Set_Attribute_Name for Name_Unaligned_Valid.
13015 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13016 Gary Dismukes <dismukes@adacore.com>
13018 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13019 If the initialization is the equivalent aggregate of the initialization
13020 procedure of the type, do not remove it.
13021 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13022 initialized to null from having their expression reset to empty and
13023 note this exception in the comment.

13028 Gary Dismukes <dismukes@adacore.com>
13030 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13031 Add "with" and "use" clauses for Sem_Attr.
13032 (Expand_Current_Value): Do not replace occurences of attribute
13033 references where the prefix must be a simple name.
13035 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13036 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13037 Attribute_Requires_Simple_Name_Prefix.
13038 (Name_Modifies_Prefix): Body of new function.
13039 (Requires_Simple_Name_Prefix): Body of new function.
13040 (Resolve_Attribute, case Access): Improve error message for case of
13041 mismatched conventions.
13042 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13044 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13045 constrained subtype for a nominal unconstrained type, use its base type
13046 to check for conformance with the context.
13047 (Resolve_Attribute): Remove test of the access type being associated
13048 with a return statement from condition for performing accessibility
13049 checks on access attributes, since this case is now captured by
13050 Is_Local_Anonymous_Access.
13051 (Analyze_Access_Attribute): Set Address_Taken on entity
13052 (Analyze_Attribute, case Address): Set Address_Taken on entity
13053 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13054 validating an access attribute whose prefix is a current instance.
13055 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13056 applied to dispatching operations, if freezing is required then we set
13057 the attribute Has_Delayed_Freeze in the prefix's entity.
13058 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13059 current scope if access of local subprogram taken
13060 (Analyze_Access_Attribute): Check legality of self-reference even if the
13061 expression comes from source, as when a single component association in
13062 an aggregate has a box association.
13063 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13064 the prefix if it is a protected operation and the attribute is
13065 Unrestricted_Access.
13066 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13067 reference to the base type of the context, to force a constraint check
13068 when the context is an access subtype with an explicit constraint.
13069 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13070 node is rewritten as an interface conversion. leave unanalyzed after
13071 resolution, to ensure that type checking against the context will take

13075 Javier Miranda <miranda@adacore.com>
13076 Robert Dewar <dewar@adacore.com>
13078 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13079 wrapper when the full view of the controlling type of an inherited
13080 function that dispatches on result implements interfaces.
13081 (Expand_N_Object_Declaration): In cases where the type of the
13082 declaration is anonymous access, create finalization list for it.
13083 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13084 if the object has no explicit initialization, to match description of
13085 functionality of pragam Persistent_BSS.
13086 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13087 new function to build static aggregates, to replace initialization call
13088 when static initialization is desired.
13089 (Freeze_Type): Generate a list controller for an access type whenever
13090 its designated type has controlled anonymous access discriminants.
13091 (Build_Equivalent_Aggregate): New procedure to compute a static
13092 aggregate to be used as default initialization for composite types,
13093 instead of a generating a call to the initialization procedure for the
13095 (Build_Initialization_Call): When available, replace a call to the
13096 initialization procedure with a copy of the equivalent static aggregate
13098 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13099 declarations for objects of a class-wide interface type, rather than
13100 just identifiers, to prevent visibility problems.
13101 (Expand_N_Object_Declaration): When expanding the declaration for an
13102 object of a class-wide interface type, preserve the homonym chain of
13103 the original entity before exchanging it with that of the generated
13104 renaming declaration.
13105 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13106 active, because there is no way to handle the exception.
13107 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13108 to do a minimum decoration of the Access_Disp_Table list.
13109 (Expand_Record_Controller): Avoid the addition of the controller between
13110 the component containing the tag of a secondary dispatch table and its
13111 adjacent component that stores the offset to the base of the object.
13112 This latter component is only generated when the parent type has
13113 discriminants ---documented in Add_Interface_Tag_Components).
13114 (Apply_Array_Size_Check): Removed, no longer needed.
13115 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13116 components, create a Master_Entity for it only if it contains tasks.
13117 (Build_Init_Procedure): Suppress the tag assignment compiling under
13119 (Freeze_Record_Type): Remove code associated with creation of dispatch
13121 (Init_Secondary_Tags): Update type of actuals when generating calls to
13122 Ada.Tags.Set_Offset_To_Top
13123 (Stream_Operation_OK): Disable use of streams compiling under no
13125 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13126 if Has_Init_Expression set.
13127 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13128 Register_Primitive, which provides the same functionality.
13129 (Requires_Init_Proc): Return false in case of interface types.
13130 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13132 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13133 is always associated with a predefined primitive because the internal
13134 entities associated with interface types are not predefined primitives.
13135 Therefore, the call to Is_Internal is replaced by a call to the
13136 function Is_Predefined_Dispatching_Operation.
13137 (Make_Eq_If): When generating the list of comparisons for the
13138 components of a given variant, omit the controller component that is
13139 present if the variant has controlled components.
13141 2007-06-06 Javier Miranda <miranda@adacore.com>
13142 Hristian Kirtchev <kirtchev@adacore.com>
13143 Bob Duff <duff@adacore.com>
13145 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13146 handle the creation of finalization lists and calls for nested
13147 coextensions when the root of the chains is part of a return statement.
13148 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13150 (Expand_Record_Equality): Skip components that are interface types.
13151 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13152 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13153 with Rewrite_Coextension. Change the condition for detecting coextension
13155 (Is_Local_Access_Discriminant): Removed.
13156 (Rewrite_Coextension): New routine which rewrites a static coextension
13157 as a temporary and uses its unrestricted access in the construction of
13159 (Complete_Coextension_Finalization): New routine. Generate finalization
13160 attachment calls to all delayed coextensions.
13161 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13162 the allocator is not a coextension itself and has delayed coextensions.
13163 If the current allocator is controlled, but also a coextension, delay
13164 the generation of the finalization attachment call.
13165 Rename local variable "Node" to "Nod" in order to avoid confusion with
13167 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13168 limited types that are not inherently limited. Such an allocator is
13169 illegal, but is generated by the expander for a return statement, to
13170 copy the result onto the secondary stack. This is the only case where a
13171 limited object can be copied. Generate code to displace the pointer
13172 to the object if the qualified expression is a class-wide interface
13173 object. Such displacement was missing and hence the copy of the object
13175 (Apply_Accessibility_Check): Handle allocated objects initialized in
13177 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13178 and Expand_Allocator_Expression. Allocating class-wide interface objects
13179 this routine displaces the pointer to the allocated object to reference
13180 the component referencing the corresponding secondary dispatch table.
13181 Expand_Allocator_Expression): Add missing support to allocate class-wide
13182 interface objects initialized with a qualified expression.
13183 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13184 function result type, and use the finalization list associated with the
13185 function scope in that case (such an anonymous type should not be
13186 treated like an access parameter's type).
13188 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13189 Gary Dismukes <dismukes@adacore.com>
13190 Javier Miranda <miranda@adacore.com>
13192 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13193 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13194 required exception handler.
13195 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13196 properly the case of a function whose return type is a limited
13197 class-wide interface type. Modify the code of the accessibility
13198 check to handle class-wide interface objects. In this case we need to
13199 displace "this" to reference the primary dispatch table to get access
13200 to the TSD of the object (to evaluate its accessibility level).
13201 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13202 rather than a controlling result as one of the conditions for
13203 generating tests of the implicit BIP_Alloc_Form formal. The
13204 initialization assignment is also handled according to whether the
13205 result is tagged instead of controlling.
13206 In the case where the init assignment is inserted in the "then" part of
13207 the allocation conditional, rewrite the target to be a dereference of
13208 the implicit BIP_Object_Access formal.
13209 If the returned value is unconstrained and created on the secondary
13210 stack, mark the enclosing block and function so that the secondary
13211 stack is not reclaimed on return.
13212 Treat returns from functions with controlling results similarly to
13213 returns from functions with unconstrained result subtypes.
13214 If the object returned is unconstrained, and an allocator must be
13215 created for it, analyze the allocator once the block for the extended
13216 return is installed, to ensure that finalizable components
13217 of the expression use the proper finalization list. Guard the call to
13218 Move_Final_List with a check that there is something to finalize.
13219 (Make_Tag_Ctrl_Assignment): Use "old" handling
13220 of controlled type assignment for virtual machines, since new code uses
13221 unsupported features (such as direct access to bytes in memory).
13223 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13224 Ed Schonberg <schonberg@adacore.com>
13226 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13227 accessibility actual, check for the case of an aliased object that has
13228 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13229 we fall into processing for the attribute rather than the name of the
13231 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13232 formal has its address taken in the body, create a temporary to capture
13233 value. If the return type is a limited interface, do not treat the
13234 return value as Controlled.
13235 (Is_In_Place_Function): If the return type is a limited interface,
13236 treat as returning in place. The actual returned object may not always
13237 be limited, but the caller has to assume that it is returned in place.
13238 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13239 context of an allocator, use the correct finalization chain (that is,
13240 the chain belonging to the access type, rather than the chain belonging
13241 to the current scope).
13242 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13243 result type rather than a controlling result as a precondition for
13244 adding an allocation form actual to a build-in-place call.
13245 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13246 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13247 primitive in the dispatch tables. This work is now done by Make_DT when
13248 the type is frozen.
13249 (Register_Predefined_DT_Entry): Removed.
13250 (Add_Return): If end label is not present, use sloc of last statement
13251 for generated return statement in procedure, for better gdb behavior
13253 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13254 object address nodes to ensure proper processing by routines like
13256 (Expand_Call): Fix generation of validity check for parameter
13257 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13258 the allocation form parameter if the result subtype is constrained,
13259 except when the function has a controlling result.
13260 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13261 rather than Is_Controlled and Has_Controlled_Component, since we want to
13262 include class-wide result types in this treatment. Also test for a
13263 controlling result, since that also requires passing a finalization
13265 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13266 even when the result subtype is constrained, to handle calls involving
13267 controlling results.
13268 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13269 is now called even when the result subtype is constrained, to handle
13270 calls involving controlling results.
13271 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13272 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13273 now performs the test).
13274 (Make_Build_In_Place_Call_In_Object_Declaration):
13275 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13276 constrained, to handle calls involving controlling results.
13277 (Add_Return): Accomodate rewritten pattern from local raise to goto
13278 transformation, so that we still recognize an transfer statement
13279 and do the right thing here in that case.
13280 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13281 and end of subprogram code.
13282 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13283 support for primitives that are functions (without formals) with a
13284 controlling result.
13285 (Inherited_From_Formal): If the actual subtype has not generic parent
13286 type, it is not an actual for a formal derived type, and there is no
13287 operation to inherit from the formal.
13289 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13290 Thomas Quinot <quinot@adacore.com>
13292 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13293 inserted cleanup code appropriately for GDB use.
13294 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13295 exception handler for Deep_Adjust or Deep_Finalize.
13296 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13297 Raise_From_Controlled_Operation is available, use a call to that
13298 subprogram instead of a plain "raise Program_Error" node to raise
13299 Program_Error if an exception is propagated from an Adjust or Finalize
13301 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13302 appears in the optional statement list of a triggering alternative, the
13303 scope actions can be inserted directly there, and not in the list that
13304 includes the asynchronous select itself.
13306 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13307 Robert Dewar <dewar@adacore.com>
13308 Hristian Kirtchev <kirtchev@adacore.com>
13310 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13311 generated exception handler appropriately when debugging generated code.
13312 Deal properly with No_Exception_Propagation restriction mode.
13313 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13314 System.Address to System.Tasking.Task_Id when processing the result of
13315 the predefined primitive _disp_get_task_id.
13316 (Expand_N_Asynchronous_Select): Clarify comment.
13317 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13318 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13319 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13320 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13321 privals and for generated call to Complete_Entry_Body, for better gdb
13323 (Copy_Result_Type): Utility to construct a parameter and result profile
13324 for protected functions whose return type is an anonymous access to
13326 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13328 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13329 point when the local-raise-to-goto transformation has taken place.
13331 2007-06-06 Javier Miranda <miranda@adacore.com>
13332 Nicolas Setton <setton@adacore.com>
13334 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13335 functionality when the backend is generating code.
13336 Otherwise any serious error
13337 reported by the backend calling the frontend routine Error_Msg
13338 changes the Compilation_Mode to Check_Semantics, disables the
13339 functionality of this routine and causes the generation of
13340 spureous additional errors.
13342 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13343 debugging information now generated by the compiler for fat-pointer
13345 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13347 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13349 2007-06-06 Thomas Quinot <quinot@adacore.com>
13351 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13352 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13353 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13354 For a remote call to a function with a classwide return type, apply an
13355 E.4(18) check to the returned value.
13356 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13357 stream attributes of the designated type of an RACW, as they are not
13358 dispatching primitive operations.
13360 2007-06-06 Geert Bosch <bosch@adacore.com>
13362 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13364 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13366 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13367 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13369 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13371 2007-06-06 Javier Miranda <miranda@adacore.com>
13373 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13374 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13376 2007-06-06 Javier Miranda <miranda@adacore.com>
13378 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13379 deallocation of class-wide interface objects.
13380 (Expand_Dispatching_Constructor_Call): Take into account that if the
13381 result of the dispatching constructor is an interface type, the
13382 function returns a class-wide interface type; otherwise the returned
13383 object would be actual. The frontend previously accepted returning
13384 interface types because Expand_Interface_Actuals silently performed
13385 the management of the returned type "as if" it were a class-wide
13387 (Expand_Dispatching_Constructor_Call): Replace call to
13388 Make_DT_Access_Action by direct call to Make_Function_Call.
13390 2007-06-06 Robert Dewar <dewar@adacore.com>
13391 Ed Schonberg <schonberg@adacore.com>
13393 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13394 compute masking constant, since we now set Esize properly to the
13396 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13397 to match the alignment.
13398 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13399 packed arrays of 8 bits or less.
13401 * freeze.adb (Freeze_Entity): When freezing the formals of a
13402 subprogram, freeze the designated type of a parameter of an access type
13403 only if it is an access parameter.
13404 Increase size of C convention enumeration object
13405 (Freeze_Entity, array type case): Make sure Esize value is properly
13406 adjusted for the alignment if it is known.
13407 (Freeze_Entity, array type case): When checking bit packed arrays for
13408 the size being incorrect, check RM_Size, not Esize.
13409 (Freeze_Record_Type): Check for bad discriminated record convention
13410 (In_Exp_Body): Return true if the body is generated for a subprogram
13411 renaming, either an attribute renaming or a renaming as body.
13412 (Check_Itype): If the designated type of an anonymous access component
13413 is a non-protected subprogram type, indicate that it is frozen, to

15359 attempt to derive from a synchronized tagged type.
15360 (Analyze_Type_Declaration): If there is a incomplete tagged view of the

15450 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15451 when -gnatg is not specified.

15481 (Convert_Aggr_In_Allocator): If the allocator is for an access
15482 discriminant and the type is controlled. do not place on a finalization
15483 list at this point. The proper list will be determined from the

15503 parameter of the containing subprogram.
15504 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15505 under No_Dispatching_Calls restriction. During the semantic analysis
15506 we already notified such violation.

15528 value that is used in the membership test but also to fix the size
15529 of the table of ancestors.
15530 (Expand_Interface_Conversion): Insert function body at the closest place

15655 Pablo Oliveira <oliveira@adacore.com>
15657 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15658 Do an Unchecked_Conversion to handle the passage from the Underlying
15659 Type to the Base Type when calling Build_To_Any_Call and
15660 Build_From_Any_Call.
15661 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15662 E_Constant, depending upon Variable formal.
15663 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15664 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15665 parameter that requires an extra constrained parameter, declare
15666 temporary for actual as a variable, not a constant.
15667 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15668 the unit being compiled is the one that contains the stub type.
15669 Change primitive operation name for the RACW associated with a RAS
15670 from Call to _Call so it cannot clash with any legal identifier.
15671 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15673 (Append_RACW_Bodies): New subprogram.
15674 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15675 Add_Receiving_Stubs_To_Declarations functions.
15676 When expanding a package body, this list correspond to the
15677 statements in the HSS at the end of the pacakge.
15678 When expanding a package spec, this list correspond to the
15680 (Add_Receiving_Stubs_To_Declarations): Append the function
15681 registering the receiving stubs at the end of the 'Stmts' list.
15682 (RCI_Package_Locator): Pass the new Version generic formal when
15683 instantiating a RCI_Locator package.
15684 (Build_From_Any_Function): To compute the High bound for an
15685 unconstrained array actual, we add the Low bound with the length.
15686 Thus we must convert the low bound and the length to an appropriate
15687 type before doing the sum.
15688 (Build_Subprogram_Receiving_Stubs, PolyORB):
15689 * Retrieve the extra formals parameters at the
15690 end of the parameter stream.
15691 * Use Move_Any_Value to write back out parameters
15692 after executing the request as it is more efficient
15693 than Copy_Any_Value.
15694 * Build the any containing Extra Formals with the
15695 appropriate typecode.
15696 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15697 empty Component_List.
15698 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15699 the tree the declaration for an object that serves as actual parameter
15700 in server-side stubs.
15701 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15702 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15703 Use Build_Actual_Object_Declaration to prepare the actuals.
15704 (Add_Parameter_To_NVList): Set the parameter mode to In for
15705 Extra Constrained Parameters.
15706 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15707 Extra Constrained parameters.
15708 (Build_To_Any_Function, Build_From_Any_Function,
15709 Built_TypeCode_Function): When Typ is implicit, call the correct
15710 function with the first not implicit parent type.
15711 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15712 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15713 typecode from the Etype. Therefore we retrieve the correct typecode
15714 with a call to Get_Any_Type.
15715 (Copy_Specification): Do controlling formal type substitution based on
15716 Is_Controlling_Formal flag, instead of caller-provided object type.
15717 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15718 a RACW primitive operation, we might get a subprogram declaration for an
15719 ancestor of the RACW designated type (not for the designated type
15720 itself), in the case where this operation is inherited. In this case we
15721 have no easy means of determining the original tagged type for which
15722 the primitive was declared, so instead we now rely on
15723 Copy_Specification to use the Is_Controlling_Formal flag to determine
15724 which formals require type substitution.

15730 GNAT.Current_Exception are not allowed if pragma Restrictions
15731 (No_Exception_Propagation) is set and in any case make the associated
15732 handler unsuitable as a target for a local raise statement.
15733 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15734 run-time subprogram CW_Membership by call to Build_CW_Membership.
15735 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15736 by a function call, a temporary must be created before expanding the
15737 Constructor_Call itself, to prevent out-of-order elaboration in the
15738 back-end when stack checking is enabled..
15740 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15742 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15743 result are the bounds of the left operand, not the right.
15745 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15748 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
15749 discriminant defaults.

15760 box corresponds to a component of the type.
15761 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15762 Is_Abstract_Subprogram and Is_Abstract_Type.
15764 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
15767 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
15768 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
15769 called only when appropriate.

15867 standard 8bits encoding.
15868 (WS2SU): As above but converting from wide-sring to string.
15869 This is needed as it is necessary to have access to both versions in the
15870 runtime for the form parameter encoding support.
15871 This set of patch add support for the encoding form parameter.
15872 (S2WS): Improve implementation to handle cases where the filename is not
15873 UTF-8 encoded. In this case we default to using the current code page
15874 for the conversion.

15924 implementation of floating point operations as native x86 targets.
15925 So the FPU should be initialized in the same way using finit. Fix
15926 floating point operations accuracy issues.
15927 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15928 member in struct sigaction, so as to avoid warning for incompatible

16120 Use First/Next_Component_Or_Discriminant
16121 (Check_Component_Overlap): Use First/Next_Component_Or_Discriminant
16122 (Analyze_Attribute_Definition_Clause, case Value_Size): Reject
16123 definition if type is unconstrained.
16124 (Adjust_Record_For_Reverse_Bit_Order): New procedure
16125 (Analyze_Attribute_Definition_Clause): Split Is_Abstract flag into
16126 Is_Abstract_Subprogram and Is_Abstract_Type.
16127 (Adjust_Record_For_Reverse_Bit_Order): New procedure
16129 * repinfo.adb (List_Record_Info): Use First/
16130 Next_Component_Or_Discriminant.
16132 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
16135 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch
16136 Include -gnatyA in default switches
16138 * opt.ads: (Warn_On_Non_Local_Exception): New flag
16139 (Warn_On_Reverse_Bit_Order): New flag
16140 (Extensions_Allowed): Update the documentation.
16141 (Warn_On_Questionable_Missing_Parens): Now on by default
16143 * usage.adb: Add documentation of -gnatw.x/X switches
16144 Document new -gnatyA style switch
16145 -gnatq warnings are on by default
16147 2007-04-06 Ed Falis <falis@adacore.com>
16149 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16150 full word is no longer compared twice.
16152 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16154 * sem_ch10.adb (Install_Limited_Context_Clauses.
16155 Expand_Limited_With_Clause): Use a new copy of selector name in the
16156 call to Make_With_Clause. This fixes the tree structure for ASIS
16157 purposes. Nothing is changed in the compiler behaviour.
16158 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16159 a package renaming.
16160 (Install_Limited_With_Clauses): Do not install non-limited view when it
16161 is still incomplete.
16163 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16164 Gary Dismukes <dismukes@adacore.com>
16166 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16167 when capturing size information, instead of base type, which for a
16168 formal array type will be the unconstrained type.
16169 (Analyze_Formal_Object_Declaration): Add check for illegal default
16170 expressions for a formal in object of a limited type.
16171 (Instantiate_Object): Ditto.
16172 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16173 because they were defaulted in the formal package and no check applies
16175 (Check_Formal_Package_Instance): Extend conformance check to other
16176 discrete types beyond Integer.
16177 (Process_Default): Copy directly the unmatched formal. A generic copy
16178 has already been performed in Analyze_Formal_Package.
16179 (Analyze_Associations): If a formal subprogram has no match, check for
16180 partial parametrization before looking for a default, to prevent
16182 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16183 not set the instantiation environment before analyzing the actuals.
16184 Fixes regression on 8515-003 with implementation of AI-133.
16185 Set_Instance_Env checks whether the generic unit is a predefined
16186 unit, in which case the instance must be analyzed with the latest Ada
16187 mode. This setting must take place after analysis of the actuals,
16188 because the actuals must be analyzed and frozen in the Ada mode extant
16189 outside of the current instantiation.
16190 (Save_Env, Restore_Env): Preserve and restore the configuration
16191 parameters so that predefined units can be compiled in the proper Ada
16193 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16194 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16195 and Is_Abstract_Type.
16196 (Analyze_Formal_Package): For better error recovery, Add exception
16197 handler to catch Instantion_Error, which can be raised in
16198 Analyze_Associations
16200 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16201 Bob Duff <duff@adacore.com>
16202 Gary Dismukes <dismukes@adacore.com>
16204 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16205 prefix type is a discriminated subtype of the type of the formal.
16206 (Analyze_Allocator): Collect all coextensions regardless of the context.
16207 Whether they can be allocated statically is determined in exp_ch4.
16208 (Analyze_Selected_Component): If the prefix is a limited view and the
16209 non-limited view is available, use the non-limited one.
16210 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16211 therefore illegal), suggest a qualified expression rather than a type
16212 conversion, because a type conversion would be illegal in this context.
16213 (Anayze_Allocator): Trace recursively all nested allocators so that all
16214 coextensions are on the corresponding list for the root. Do no mark
16215 coextensions if the root allocator is within a declaration for a stack-
16216 allocated object, because the access discriminants will be allocated on
16218 (Analyze_Call): Remove restriction on calls to limited functions for the
16219 cases of generic actuals for formal objects, defaults for formal objects
16220 and defaults for record components.
16221 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16222 element list. Their expansion is delayed until the enclosing allocator
16223 is processed and its finalization list constructed.
16224 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16225 for an operation with the given name among the primitive operations of
16226 the corresponding record type.
16227 (Analyze_Selected_Component): If the prefix is a task type that
16228 implements an interface, and there is no entry with the given name,
16229 check whether there is another primitive operation (e.g. a function)
16231 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16232 properly the indexing of a function call written in prefix form, where
16233 the function returns an array type, and all parameters of the function
16234 except the first have defaults.
16235 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16236 the original operands, rather than relocating them, for efficiency and
16237 to work properly when an operand is overloaded.
16238 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16239 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16240 (Analyze_Selected_Component): If the prefix is a private extension, only
16241 scan the visible components, not those of the full view.
16242 (Try_Primitive_Operation): If the operation is a procedure, collect all
16243 possible interpretations, as for a function, because in the presence of
16244 classwide parameters several primitive operations of the type can match
16245 the given arguments.
16247 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16248 Robert Dewar <dewar@adacore.com>
16250 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16251 tag-indeterminate call to an abstract function, when the left-hand side
16253 (Analyze_Loop_Statement): Improve detection of infinite loops
16255 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16256 Thomas Quinot <quinot@adacore.com>
16258 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16259 out of Analyze_Package_Declaration, because processing must be applied
16260 to package bodies as well, for deferred constants completed by pragmas.
16261 (Analyze_Package_Declaration): When the package declaration being
16262 analyzed does not require an explicit body, call Check_Completion.
16263 (May_Need_Implicit_Body): An implicit body is required when a package
16264 spec contains the declaration of a remote access-to-classwide type.
16265 (Analyze_Package_Body): If the package contains RACWs, append the
16266 pending subprogram bodies generated by exp_dist at the end of the body.
16267 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16268 Is_Abstract_Subprogram and Is_Abstract_Type.
16269 (Preserve_Full_Attributes): The full entity list is not an attribute
16270 that must be preserved from full to partial view.
16272 * sem_dist.adb (Add_RAS_Dereference_TSS):
16273 Change primitive name to _Call so it cannot clash with any legal
16274 identifier, and be special-cased in Check_Completion.
16275 Mark the full view of the designated type for the RACW associated with
16276 a RAS as Comes_From_Source to get proper view switching when installing
16277 private declarations.
16278 Provite a placeholder nested package body along with the nested spec
16279 to have a place for Append_RACW_Bodies to generate the calling stubs
16280 and stream attributes.
16282 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16283 Robert Dewar <dewar@adacore.com>
16285 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16286 that is a limited view, check the non-limited view if available.
16287 (Undefined): Refine error message for missing with of Text_IO
16288 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16289 to distinguish real missing with cases.
16290 Fix format of all missing with messages
16291 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16292 renaming as body when renamed entity is abstract.
16294 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16295 Javier Miranda <miranda@adacore.com>
16297 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16298 predicate recursive, to handle complex expressions on literals whose
16299 spurious ambiguity comes from the abstract interpretation of some
16301 (Interface_Present_In_Ancestor): Add support to concurrent record
16303 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16304 Is_Abstract_Subprogram and Is_Abstract_Type.
16306 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16307 Javier Miranda <miranda@adacore.com>
16309 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16310 dereference of a local object R created as a reference to another
16311 object O, use the access level of O.
16312 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16313 rather than local Same_Formal_Type, to check whether protected operation
16314 overrides an inherited one.
16315 (Same_Formal_Type): New predicate, used when matching signatures of
16316 overriding synchronized operations, to handle the case when a formal
16317 has a type that is a generic actual.
16318 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16319 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16320 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16321 syntactic ambiguities involving indexing of function calls that return
16323 (Abstract_Interface_List): New subprogram that returns the list of
16324 abstract interfaces associated with a concurrent type or a
16325 concurrent record type.
16326 (Interface_Present_In_Parent): New subprogram used to check if a
16327 given type or some of its parents implement a given interface.
16328 (Collect_Abstract_Interfaces): Add support for concurrent types
16329 with interface types.
16330 (Has_Abstract_Interfaces): Add support for concurrent types with
16332 (Is_Parent): New subprogram that determines whether E1 is a parent
16333 of E2. For a concurrent type its parent is the first element of its
16334 list of interface types; for other types this function provides the
16335 same result than Is_Ancestor.
16336 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16337 (Collect_Synchronized_Interfaces): Removed because the subprogram
16338 Collect_Abstract_Interfaces provides this functionality.
16339 (Collect_Abstract_Interfaces): Minor update to give support to
16340 concurrent types and thus avoid undesired code duplication.
16341 (Get_Subprogram_Entity): Handle entry calls.
16342 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16344 (Enter_Name): Do not give -gnatwh hiding warning for record component
16345 entities, they never result in hiding.

16354 New field Exception_Label added
16355 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16356 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

16358 correspond to access discriminants of dynamically allocated objects.
16359 (N_Block_Statement): Document the fact that the corresponding entity
16360 can be an E_Return_Statement.
16361 (Is_Coextension): New flag for allocators.
16362 Remove all code for DSP option

16380 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16381 expression with a COMPOUND_EXPR including the call instead of emitting
16382 the call directly here.
16383 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16384 high bound is constant and the slice is empty. Tidy.
16385 (tree_transform, case N_Op_Not): Handle properly the case where the
16386 operation applies to a private type whose full view is a modular type.
16387 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16388 Address_Clause, use the associated Expression as the GNAT tree
16389 representing the choice value to ensure the corresponding GCC tree is
16390 of the proper kind.
16391 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16392 instead of just the operands, as the base GCC stabilize_reference does.
16393 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16394 requested; otherwise fail.
16395 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

16400 implementation of UI_Div.
16401 (UI_Div): Reimplement as a call to UI_Div_Rem.
16402 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16403 remainder, avoiding the cost of a multiplication and a subtraction.
16404 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16405 provides both quotient and remainder in a single computation.
16406 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16407 functions for uint.
16408 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram

16420 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16421 when updating the contents of the old pointer to an unconstrained array.
16422 (end_subprog_body): Set error_gnat_node to Empty.
16423 (write_record_type_debug_info): Do not be unduly sparing with our bytes.

16655 (mainly static expression evaluation).
16656 Reword some continuation messages
16657 Add some \\ sequences to continuation messages
16658 (Resolve_Call): Refine infinite recursion case. The test has been

16672 during analysis, and use May_Be_Lvalue to distinguish read/write.
16673 (Valid_Array_Conversion): New procedure, abstracted from
16674 Valid_Conversion, to incorporate accessibility checks for arrays of
16675 anonymous access types.
16676 (Valid_Conversion): For a conversion to a numeric type occurring in an
16677 instance or inlined body, no need to check that the operand type is
16678 numeric, since this has been checked during analysis of the template.

16961 alignment of a field in a variant record might not be accurate. Add a
16962 safety test to make sure no alignment is set to a smaller value than
16963 the alignment of the field type.

17266 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17267 assignments where the target subtype is unconstrained and the target
17268 object is a parameter or dereference (other aliased cases are known

17434 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17435 an aliased prefix must be known to be constrained in order to use True
17436 for the attribute value, and now it's possible for some aliased views

17455 generate the wrapper if the parent primitive is abstract. This is
17456 required to report the correct error message.
17457 (Expand_N_Subtype_Indication): Do validity checks on range
17458 (Clean_Task_Names): If an initialization procedure includes a call to
17459 initialize a task (sub)component, indicate that the procedure will use
17460 the secondary stack.
17461 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17462 compatibility for interfacing with CPP by default.
17463 (Expand_N_Object_Declaration): Only build an Adjust call when the
17464 object's type is a nonlimited controlled type.
17465 * exp_ch3.adb: Add with and use of Exp_Ch6.
17466 (Expand_N_Object_Declaration): Check for object initialization that is a
17467 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17468 Object_Declaration to the call.
17469 (Freeze_Type): When the designated type of an RACW was not frozen at the
17470 point where the RACW was declared, validate the primitive operations
17471 with respect to E.2.2(14) when it finally is frozen.
17472 (Build_Initialization_Call,Expand_Record_Controller): Rename
17473 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17474 return-by-reference has no meaning in Ada 2005.
17475 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17476 to register tag of the immediate ancestor interfaces in the
17477 run-time structure.
17478 (Init_Secondary_Tags): Moved to the specification to allow the
17479 initialization of extension aggregates with abstract interfaces.
17480 (Build_Master_Renaming): Make public, for use by function declarations
17481 whose return type is an anonymous access type.
17482 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17483 Insert_List_Before_And_Analyze after the generation of the specs
17484 associated with null procedures.
17485 (Expand_Tagged_Root): Update documentation in its specification.
17486 (Init_Secondary_Tags): Update documentation.
17487 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17488 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17489 then generate code to inherit the contents of the dispatch table
17490 directly from the ancestor.
17491 (Expand_Record_Controller): Insert controller component after tags of
17492 implemented interfaces.
17493 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17494 create null procedure overridings when null procedures are inherited
17496 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17497 declarations for overriding null primitives inherited from interfaces.
17498 (Is_Null_Interface_Procedure): New function in
17499 Make_Null_Procedure_Specs.
17500 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17501 immediate ancestor of a tagged type is an abstract interface type we
17502 must generate the specification of the predefined primitives associated
17503 with controlled types (because the dispatch table of the ancestor is
17504 null and hence these entries cannot be inherited). This is required to
17505 elaborate well the dispatch table.

17513 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17515 (Expand_N_In): Do validity checks on range
17516 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17517 (Expand_N_Allocator): For "new T", if the object is constrained by
17518 discriminant defaults, allocate the right amount of memory, rather than
17519 the maximum for type T.
17520 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17521 when the allocator is initialized by a build-in-place call, since the
17522 allocator is already rewritten as a reference to the function result,
17523 and this prevents an unwanted duplication of the function call.
17524 Add with and use of Exp_Ch6.
17525 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17526 is a call to build-in-place function and apply
17527 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17528 untagged designated types).
17529 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17530 optimization if source or target is biased.
17531 (Expand_N_Allocator): Add comments for case of an allocator within a
17532 function that returns an anonymous access type designating tasks.
17533 (Expand_N_Allocator): apply discriminant checks for access
17534 discriminants of anonymous access types (AI-402, AI-416)

17539 Ed Schonberg <schonberg@adacore.com>
17541 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17543 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17544 (Expand_N_Assignment_Statement): Call
17545 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17546 build-in-place function call. Currently, this can happen only for
17547 assignments that come from aggregates.
17548 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17549 in order to alleviate the upward compatibility introduced by AI-318.
17550 (Expand_N_Extended_Return_Statement): Add support for handling the
17551 return object as a build-in-place result.
17552 (Expand_Non_Function_Return): Implement simple return statements nested
17553 within an extended return.
17554 (Enable_New_Return_Processing): Turn on the new processing of return
17556 (Expand_Non_Function_Return): For a return within an extended return,
17557 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17558 (Expand_N_Extended_Return_Statement): Implement AI-318
17559 (Expand_Simple_Function_Return): Ditto.
17560 (Expand_N_If_Statement): Handle new -gnatwt warning
17561 (Expand_N_Case_Statement): Handle new -gnatwt warning
17562 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17563 a protected object.
17564 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17565 validity checking of assignments to elementary record components.
17566 (Expand_N_Return_Statement): return Class Wide types on the secondary
17567 stack independantly of their controlled status since with HIE runtimes,
17568 class wide types are not potentially controlled anymore.
17570 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17573 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17574 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17575 it expects a block, procedure, or task. The return statement will get
17576 turned into a block, and Expand_Cleanup_Actions will happen then.

17579 Ed Schonberg <schonberg@adacore.com>
17580 Bob Duff <duff@adacore.com>
17581 Gary Dismukes <dismukes@adacore.com>
17583 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17585 (Expand_Inlined_Call): Tagged types are by-reference types, and
17586 therefore should be replaced by a renaming declaration in the expanded
17587 body, as is done for limited types.
17588 (Expand_Call): If this is a call to a function with dispatching access
17589 result, propagate tag from context.
17590 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17592 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17593 build-in-place when the right-hand side of an assignment is a
17594 build-in-place function call.
17595 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17596 of the explicit dereference of the allocator to the result subtype of
17597 the build-in-place function. This is needed to satisfy type checking
17598 in cases where the caller's return object is created by an allocator for
17599 a class-wide access type and the type named in the allocator is a
17601 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17602 conversion of the reference to the declared object to the result subtype
17603 of the build-in-place function. This is needed to satisfy type checking
17604 in cases where the declared object has a class-wide type. Also, in the
17605 class-wide case, change the type of the object entity to the specific
17606 result subtype of the function, to avoid passing a class-wide object
17607 without explicit initialization to the back end.
17608 (Register_Interface_DT_Entry): Moved outside the body of
17609 Freeze_Subprogram because this routine is now public; it is called from
17610 Check_Dispatching_Overriding to handle late overriding of abstract
17611 interface primitives.
17612 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17613 adding an implicit access actual on a call to a build-in-place function.
17614 (Expand_Actuals): Test for an actual parameter that is a call to a
17615 build-in-place function and apply
17616 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17617 (Is_Build_In_Place_Function): New function to determine whether an
17618 entity is a function whose calls should be handled as build-in-place.
17619 (Is_Build_In_Place_Function_Call): New function to determine whether an
17620 expression is a function call that should handled as build-in-place.
17621 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17622 calls to build-in-place functions as the initialization of an allocator.
17623 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17624 handling calls to build-in-place functions in contexts that do not
17625 involve init of a separate object (for example, actuals of subprogram
17627 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17628 handling calls to build-in-place functions as the initialization of an
17629 object declaration.
17630 (Detect_Infinite_Recursion): Add explicit parameter Process to
17631 instantiation of Traverse_Body to avoid unreferenced warning.
17632 (Check_Overriding_Inherited_Interfaces): Removed.
17633 (Register_Interface_DT_Entry): Code cleanup.
17634 (Register_Predefined_DT_Entry): Code cleanup.
17635 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17636 inlined statements if within a transient scope.
17637 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17638 formal parameters with occurrences of actuals in inlined body, establish
17639 visibility on the proper view of the actual's subtype for the body's
17641 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17642 compatibility mode and we have an imported CPP subprogram because
17643 for now we assume that imported CPP primitives correspond with
17644 objects whose constructor is in the CPP side (and therefore we
17645 don't need to generate code to register them in the dispatch table).
17646 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17647 aligned selected component.
17648 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17649 the actual of an in-mode parameter is a type conversion.
17650 (Expand_Actuals): If the call does not come from source and the actual
17651 is potentially misaligned, let gigi handle it rather than rejecting the
17652 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17653 Class Wide types as returning by reference independantly of their
17654 controlled status since with HIE runtimes class wide types are not
17655 potentially controlled anymore.
17657 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17659 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17660 references that are private components of the protected object.
17661 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17662 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17663 instantiation to deal with warnings.

17665 System_Priority as its expected type, in case the expression has not
17668 2006-10-31 Robert Dewar <dewar@adacore.com>
17670 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17671 initialization of Homonym_Len.
17672 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17673 names from fully qualified name. Fixes problem of duplicate
17674 external names differing only in the presence of such a block name.
17676 2006-10-31 Thomas Quinot <quinot@adacore.com>
17677 Pablo Oliveira <oliveira@adacore.com>
17679 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17680 subprogram Ids, even if they are not yet assigned.
17681 (Build_Subprogram_Id): It is now this function that will take care of
17682 calling Assign_Subprogram_Ids if necessary.
17683 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17684 should be done only once they are assigned.
17685 (Build_From_Any_Function, case of tagged types): Add missing call to
17687 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17688 type for an RACW type.
17689 (Add_RACW_Features): When processing an RACW declaration for which the
17690 designated type is already frozen, enforce E.2.2(14) rules immediately.
17691 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17692 special reordering of controlling formals.
17694 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17695 associated stub type for an RACW type.
17697 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17699 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17700 fixed-point operations in an integer context, i.e. as operands of a
17701 conversion to an integer type, indicate that result must be rounded.
17703 2006-10-31 Robert Dewar <dewar@adacore.com>
17705 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17706 cases, pass the encoding method, since it is now required by the run
17709 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17710 assumption that Str'First = 1.
17711 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17712 it on to the Value_Wide_Wide_Character call.
17713 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17714 properly handles a string of the form quote-encoded_wide_char-quote.
17716 * s-wchcnv.adb: Minor reformatting
17718 2006-10-31 Javier Miranda <miranda@adacore.com>
17720 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17721 run-time membership test to ensure that the constructed object
17722 implements the target abstract interface.
17724 2006-10-31 Robert Dewar <dewar@adacore.com>
17726 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17727 Machine_Attribute pragma internally to implement the user pragma.
17728 Add processing for pragma Interface so that it is now completely
17729 equivalent to pragma Import.
17731 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17732 so that it can be applied to all entities, including record components
17733 and enumeration literals.
17734 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17735 priority ranges are correct, verify compatibility against task
17736 dispatching and locking policies, and if everything is correct an entry
17737 is added to the table containing priority specific dispatching entries
17738 for this compilation unit.
17739 (Delay_Config_Pragma_Analyze): Delay processing
17740 Priority_Specific_Dispatching pragmas because when processing the
17741 pragma we need to access run-time data, such as the range of
17742 System.Any_Priority.
17743 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17744 Allow pragma Unreferenced as a context item
17745 Add pragma Preelaborable_Initialization
17746 (Analyze_Pragma, case Interface): Interface is extended so that it is
17747 now syntactically and semantically equivalent to Import.
17748 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17749 insertion characters.
17750 Add handling for Pragma_Wide_Character_Encoding
17751 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17752 never supercedes a real restriction, and that a real restriction
17753 always supercedes a warning.
17754 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17762 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17763 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17765 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17766 type of the function containing a return statement, because the
17767 Return_Type field was removed. We now use the Return_Applies_To field.
17769 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17770 (Build_Task_Image_Decl): If procedure is not called from an
17771 initialization procedure, indicate that function that builds task name
17772 uses the sec. stack. Otherwise the enclosing initialization procedure
17773 will carry the indication.
17774 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17775 N_Object_Declaration instead.
17776 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17777 conditional dead code killed, and change implementation accordingly.
17778 (Insert_Actions): Add N_Return_Object_Declaration case.

17780 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17781 attempts to save information for global variables which cannot be
17783 (Get_Current_Value_Condition): Handle conditions the other way round
17784 (constant on left). Also handle right operand of AND and AND THEN

17786 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17787 (Get_Current_Value_Condition): Handle simple boolean operands
17788 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17789 (Get_Current_Value_Condition): If the variable reference is within an
17790 if-statement, does not appear in the list of then_statments, and does
17791 not come from source, treat it as being at unknown location.
17792 (Get_Current_Value_Condition): Enhance to allow while statements to be
17793 processed as well as if statements.
17794 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17796 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17797 of loop. This is safe now that we fixed Kill_Current_Values.
17798 (OK_To_Do_Constant_Replacement): Check whether current scope is
17799 Standard, before examining outer scopes.
17801 2006-10-31 Vincent Celier <celier@adacore.com>
17803 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17804 When True, apply VMS treatment to children of packages A, G, I and S.
17807 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17809 2006-10-31 Robert Dewar <dewar@adacore.com>

17834 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17835 use clauses, to avoid messages on packages used to qualify, and also
17836 to avoid messages from obsolescent units.
17837 (Warn_On_Useless_Assignments): Don't generate messages for imported
17838 and exported variables.
17839 (Warn_On_Useless_Assignments): New procedure

17844 Change name Is_Ada_2005 to Is_Ada_2005_Only
17845 (Last_Assignment): New field for useless assignment warning
17847 2006-10-31 Olivier Hainque <hainque@adacore.com>
17849 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17850 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17852 2006-10-31 Bob Duff <duff@adacore.com>
17853 Robert Dewar <dewar@adacore.com>
17854 Ed Schonberg <schonberg@adacore.com>
17856 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17857 Ada 95 mode, because it violates the new rules for AI-318.
17859 * g-awk.ads: Use overloaded subprograms in every case where we used to
17860 have a default of Current_Session. This makes the code closer to be
17861 correct for both Ada 95 and 2005.
17863 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17864 code, relying on the fact that the compiler generates a warning
17865 instead of an error in -gnatg mode.
17867 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17868 E_Return_Statement entity kind.
17869 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.

17872 report an error if the reserved word abstract has been previously found.
17873 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17875 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17876 parenthesized range attribute usage
17877 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17879 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17880 in the syntax for extended_return_statement. This is not in the latest
17881 RM, but the ARG is expected to issue an AI allowing this.
17882 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17883 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17884 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17885 P_Return_Statement): Parse the new syntax for extended_return_statement.
17887 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17888 Output_End_Missing): Add error-recovery code for the new
17889 extended_return_statement syntax; that is, the new E_Return entry on
17892 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17893 limited to nonlimited, because otherwise we violate the new Ada 2005
17894 rules about returning limited types in function Create_AST_Handler in
17897 * sem.adb (Analyze): Add cases for new node kinds
17898 N_Extended_Return_Statement and N_Return_Object_Declaration.
17900 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17901 type is in the same category as type of context before applying check,
17902 to prevent anomalies in instantiations.
17903 (Resolve_Aggregate): Remove test for limited components in aggregates.
17904 It's unnecessary in Ada 95, because if it has limited components, then
17905 it must be limited. It's wrong in Ada 2005, because limited aggregates
17907 (Resolve_Record_Aggregate): Move check for limited types later, because
17908 OK_For_Limited_Init requires its argument to have been resolved.
17909 (Get_Value): When copying the component default expression for a
17910 defaulted association in an aggregate, use the sloc of the aggregate
17911 and not that of the original expression, to prevent spurious
17912 elaboration errors, when the expression includes function calls.
17913 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17914 were missing. We also didn't handle qualified expressions. Now also
17915 allow function calls. Use new common routine OK_For_Limited_Init.
17916 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17917 with space can upper case letter).
17919 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17920 Has_Static_Discriminants flag
17921 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17922 type with discriminants.

17924 (Build_Discriminant_Constraints): Use updated form of
17925 Denotes_Discriminant.
17926 (Process_Subtype): If the subtype is a private subtype whose full view
17927 is a concurrent subtype, introduce an itype reference to prevent scope
17929 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17930 Record_Type_Declaration): The functionality of the subprograms
17931 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17932 is now performed by a single routine.
17933 (Build_Derived_Record_Type): If the type definition includes an explicit
17934 indication of limitedness, then the type must be marked as limited here
17935 to ensure that any access discriminants will not be treated as having
17936 a local anonymous access type.
17937 (Check_Abstract_Overriding): Issue a detailed error message when an
17938 abstract subprogram was not overridden due to incorrect mode of its
17940 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17941 synchronized private extension declarations. Verify that the ancestor is
17942 a limited or synchronized interface or in the generic case, the ancestor
17943 is a tagged limited type or synchronized interface and all progenitors
17944 are either limited or synchronized interfaces.
17945 Derived_Type_Declaration): Check for presence of private extension when
17946 dealing with synchronized formal derived types.
17947 Process_Full_View): Enchance the check done on the usage of "limited" by
17948 testing whether the private view is synchronized.
17949 Verify that a synchronized private view is completed by a protected or
17951 (OK_For_Limited_Init_In_05): New function.
17952 (Analyze_Object_Declaration): Move check for limited types later,
17953 because OK_For_Limited_Init requires its argument to have been resolved.
17954 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17955 in order to alleviate the upward compatibility introduced by AI-318.
17956 (Constrain_Corresponding_Record): If the constraint is for a component
17957 subtype, mark the itype as frozen, to avoid out-of-scope references to
17958 discriminants in the back-end.
17959 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17960 this subprogram against wrong sources.
17961 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17962 discriminant of limited type completed with a protected type, when the
17963 discriminant is used to constrain a private component of the type, and
17964 expansion is disabled.
17965 (Find_Type_Of_Object): Do not treat a return subtype that is an
17966 anonymous subtype as a local_anonymous_type, because its accessibility
17967 level is the return type of the enclosing function.
17968 (Check_Initialization): In -gnatg mode, turn the error "cannot
17969 initialize entities of limited type" into a warning.
17970 (OK_For_Limited_Init): Return true for generated nodes, since it
17971 sometimes violates the legality rules.
17972 (Make_Incomplete_Declaration): If the type for which an incomplete
17973 declaration is created happens to be the currently visible entity,
17974 preserve the homonym chain when removing it from visibility.
17975 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17976 inherited subprograms.
17977 (Access_Definition): If this is an access to function that is the return
17978 type of an access_to_function definition, context is a type declaration
17979 and the scope of the anonymous type is the current one.
17980 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17981 incomplete subtype to the set of private dependents of the original
17983 (Constrain_Discriminated_Type): Emit an error message whenever an
17984 incomplete subtype is being constrained.
17985 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17986 corresponding subtype of the full view of the original incomplete type.
17987 (Check_Incomplete): Properly detect invalid usage of incomplete types

18001 Robert Dewar <dewar@adacore.com>
18003 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18004 handling executable extension manually and duplicating code.
18006 * make.adb: Implement new -S switch
18007 (Gnatmake): Use new function Osint.Executable_Name instead
18008 of handling executable extension manually.
18010 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18011 is specified, the executable name ends with this suffix.
18012 Take advantage of Osint.Executable_Name instead of duplicating code.
18014 * switch-m.adb: Recognize new gnatmake -S switch
18016 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18018 (Get_Target_Parameters): Set Executable_Extension_On_Target if

18023 2006-10-31 Vincent Celier <celier@adacore.com>
18025 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18026 call it with -static-libgcc, as there are some platforms, such as
18027 Darwin, where one of these two switches is compulsory to link.
18029 2006-10-31 Vincent Celier <celier@adacore.com>
18031 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18032 instead of ADA_PROJECT_PATH, for the project path.
18033 (Gnatls): When displaying the project path directories, use host dir
18036 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18037 names in the project path, as absolute paths may correspond to
18038 multi-valued VMS logical names.
18040 2006-10-31 Vincent Celier <celier@adacore.com>
18042 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an

18045 (Change_Dir): Remove, no longer used
18046 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18047 on Windows. Get it calling Get_Current_Dir.

18049 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18050 (Pid_To_Integer): New function to convert a Process_Id to Integer
18052 2006-10-31 Thomas Quinot <quinot@adacore.com>

18055 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18057 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18060 2006-10-31 Robert Dewar <dewar@adacore.com>

18069 2006-10-31 Robert Dewar <dewar@adacore.com>
18071 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18073 (Layout_Variant_Record): Retrieve the discriminants from the entity
18074 rather than from the type definition, because in the case of a full
18075 type for a private type we need to take the discriminants from the
18077 (Layout_Component_List): When applying the Max operator to variants with
18078 a nonstatic size, check whether either operand is static and scale that
18079 operand from bits to storage units before applying Max.
18080 (Layout_Type): In VMS, if a C-convention access type has no explicit
18081 size clause (and does not inherit one in the case of a derived type),
18082 then the size is reset to 32 from 64.
18084 2006-10-31 Vincent Celier <celier@adacore.com>
18086 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18087 its file has already been loaded, according to the unit being loaded,
18088 not to the current value of Multiple_Unit_Index.
18090 2006-10-31 Thomas Quinot <quinot@adacore.com>
18091 Eric Botcazou <ebotcazou@adacore.com>

18126 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18128 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18129 Process_Body_Clauses): If the context of a body includes a use clause
18130 for P.Q then a with_clause for P in the same body is not redundant,
18131 even if the spec also has a with_clause on P.
18132 Add missing continuation mark to error msg
18133 (Build_Limited_Views): A limited view of a type is tagged if its
18134 declaration includes a record extension.
18135 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18136 node, even if the subunit has errors. This avoids malfunction by
18137 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18138 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18139 generation of obsolescent messages for with statements (cannot do
18140 this too early, or we cannot implement avoiding the messages in the
18141 case of obsolescent units withing obsolescent units).
18142 (Install_Siblings): If the with_clause is on a remote descendant of
18143 an ancestor of the current compilation unit, find whether there is
18144 a sibling child unit that is immediately visible.
18145 (Remove_Private_With_Clauses): New procedure, invoked after completing
18146 the analysis of the private part of a nested package, to remove from
18147 visibility the private with_clauses of the enclosing package
18149 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18150 now centralized in Generate_Reference.
18151 (Install_Limited_Context_Clauses): Remove superfluous error
18152 message associated with unlimited view visible through use
18153 and renamings. In addition, at the point in which the error
18154 is reported, we add the backslash to the text of the error
18155 to ensure that it is reported as a single error message.
18156 Use new // insertion for some continuation messages
18157 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18158 to create implicit with_clause for parent unit mentioned in original
18159 limited_with_clause.
18160 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18161 unit is a child unit. For ASIS queries.
18162 (Analyze_Subunit): If the subunit appears within a child unit, make all
18163 ancestor child units directly visible again.

18178 a formal object declaration with an access definition or a subtype mark
18179 with a null exclusion.
18180 (P_Generic_Association): Handle association with box, and others_choice
18181 with box, to support Ada 2005 partially parametrized formal packages.
18183 2006-10-31 Robert Dewar <dewar@adacore.com>
18184 Javier Miranda <miranda@adacore.com>
18186 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18187 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18188 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18189 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18190 private extensions.
18191 (P_Type_Declaration): Add the new actual Abstract_Present to every call

18194 if the reserved word abstract has been previously found.
18195 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18196 object renaming declaration with an access definition or subtype mark
18197 with a possible null exclusion.

18221 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18222 on VMS, change "__" to '.' before checking the name.
18223 (Record_Ada_Source): Always add the source file name in the list of
18224 of sources, even if it is not the first time, as it is for another
18226 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18227 dot, instead of replacing only the first '_'.
18229 * prj-part.adb (Parse): Convert project file path to canonical form
18231 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18232 extended, the project id of the project extending it is recorded in its
18233 data, even when it has already been processed as an imported project.
18235 2006-10-31 Robert Dewar <dewar@adacore.com>
18237 * repinfo.adb (List_Entities): Don't list entities from renaming

18241 Robert Dewar <dewar@adacore.com>
18243 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18244 only a restriction warning is active for the given restriction. This is
18245 desirable because we do not want to modify code in the case where only
18247 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18248 causes overriding of real restrictions.
18249 Take advantage of new No_Restrictions constant.
18251 * raise.h: (__gnat_set_globals): Change profile.
18253 2006-10-31 Arnaud Charlet <charlet@adacore.com>

18281 attribute whose prefix is the type of an enclosing aggregate.
18282 Generalizes previous mechanism to handle attribute references nested
18283 arbitrarily deep within the aggregate.
18284 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18285 can appear in an aggregate if this is a default-initialized aggregate
18286 for a self-referential type.
18287 (Resolve_Attribute, case Access): Ditto.
18288 Add support for new implementation defined attribute Stub_Type.

18300 a class-wide interface to a tagged type.
18301 Add support for the attribute Priority.
18302 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18303 whether the designated type is discriminated with a constrained partial
18304 view and require static matching in that case.
18305 Add local variable Des_Btyp. The Designated_Type
18306 of an access to incomplete subtype is either its non-limited view if
18307 coming from a limited with or its etype if regular incomplete subtype.
18309 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18310 Fix predicate to identify and allow cases of (expander-generated)
18311 references to tag of designated object of a RACW.
18312 (Validate_Static_Object_Name): In Ada 2005, a formal object is

18323 2006-10-31 Robert Dewar <dewar@adacore.com>
18325 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18326 useless assignments here and conditionalize it on absence of exception
18328 (Analyze_Exception_Handlers): Small code reorganization of error
18329 detection code, for new handling of formal packages.

18342 synchronized formal derived type is a synchronized tagged type.
18343 (Instantiate_Formal_Package): When creating the instantiation used to
18344 validate the actual package of a formal declared without a box, check
18345 whether the formal itself depends on a prior actual.
18346 (Instantiate_Formal_Subprogram): Create new entities for the defining
18347 identifiers of the formals in the renaming declaration, for ASIS use.
18348 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18349 a renaming declaration or a subtype declaration for an actual in an
18350 instance, capture location information of declaration in generic, for
18352 (Instantiate_Formal_Package): Add comments on needed additional tests.
18353 AI-317 (partial parametrization) is fully implemented.
18354 (Validate_Private_Type_Instance): Add check for actual which
18355 must have preelaborable initialization
18356 Use new // insertion for some continuation messages
18357 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18358 Default_Expression. Add type retrieval when the declaration has an
18359 access definition. Update premature usage of incomplete type check.
18360 (Check_Access_Definition): New subsidiary routine. Check whether the
18361 current compilation version is Ada 05 and the supplied node has an
18363 (Instantiate object): Alphabetize local variables. Handle the creation
18364 of new renaming declarations with respect to the kind of definition
18365 used - either an access definition or a subtype mark. Guard against
18366 unnecessary error message in the context of anonymous access types after
18367 they have been resolved. Add check for required null exclusion in a
18368 formal object declaration.
18369 (Switch_View): A private subtype of a non-private type needs to be
18370 switched (the base type can have been switched without its private
18371 dependents because of the last branch of Check_Private_View.
18372 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18374 (Instantiate_Type): Emit an error message whenever a class-wide type of
18375 a tagged incomplete type is used as a generic actual.
18376 (Find_Actual_Type): Extend routine to handle a component type in a child
18377 unit that is imported from a formal package in a parent.
18378 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18379 agree on constrainedness, rather than checking against ultimate ancestor
18380 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18381 generic body, for navigation purposes.

18384 Thomas Quinot <quinot@adacore.com>
18386 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18388 (New_Stream_Subprogram): When processing an attribute definition clause
18389 for a stream-oriented subprogram, record an entity node occurring at
18390 the point of clause to use for checking the visibility of the clause,
18391 as defined by 8.3(23) as amended by AI-195.
18392 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18393 New_Stream_Function and New_Stream_Procedure.
18394 (New_Stream_Function, New_Stream_Procedure): Removed.
18395 (Analyze_Attribute_Definition_Clause, case Address): Check new
18396 Alignment_Check check

18399 Javier Miranda <miranda@adacore.com>
18400 Robert Dewar <dewar@adacore.com>
18402 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18403 generate the same errors compiling under -gnatc.
18404 (Try_Object_Operation): If no candidate interpretation succeeds, but
18405 there is at least one primitive operation with the right name, report
18406 error in call rather than on a malformed selected component.
18407 (Analyze_Selected_Component): If the prefix is an incomplete type from
18408 a limited view, and the full view is available, use the full view to
18409 determine whether this is a prefixed call to a primitive operation.
18410 (Operator_Check): Verify that a candidate interpretation is a binary
18411 operation before checking the type of its second formal.
18412 (Analyze_Call): Add additional warnings for function call contexts not
18414 (Analyze_Allocator): Move the check for "initialization not allowed for
18415 limited types" after analyzing the expression. This is necessary,
18416 because OK_For_Limited_Init looks at the structure of the expression.
18417 Before analysis, we don't necessarily know what sort of expression it
18418 is. For example, we don't know whether F(X) is a function call or an
18419 indexed component; the former is legal in Ada 2005; the latter is not.
18420 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18421 were missing. We also didn't handle qualified expressions. Now also
18422 allow function calls. Use new common routine OK_For_Limited_Init.
18423 (Analyze_Type_Conversion): Do not perform some legality checks in an
18424 instance, because the error message will be redundant or spurious.
18425 (Analyze_Overloaded_Selected_Component): Do not do style check when
18426 setting an entity, since we do not know it is the right entity yet.
18427 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18428 (Analyze_Overloaded_Selected_Component): Same change
18429 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18430 since regular incomplete subtypes are transformed into corresponding
18431 subtypes of their full views.
18432 (Complete_Object_Operation): Treat name of transformed subprogram call
18433 as coming from source, for browsing purposes.
18434 (Try_Primitive_Operation): If formal is an access parameter, compare
18435 with base type of object to determine whether it is a primitive
18437 (Operator_Check): If no interpretation of the operator matches, check
18438 whether a use clause on any candidate might make the operation legal.
18439 (Try_Class_Wide_Operation): Check whether the first parameter is an
18440 access type whose designated type is class-wide.

18447 warn on infinite loops.
18448 Add \\ to some continuation messages
18449 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18450 (Process_Bounds): If the bounds are integer literals that result from
18451 constant-folding, and they carry a user-defined type, preserve that type
18452 rather than treating this as an integer range.
18453 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18454 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18455 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18456 left hand side of assignment.
18457 (Analyze_Assignment): Add suport to manage assigments to the attribute
18458 priority of a protected object.
18459 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18460 not just identifiers.
18461 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18462 or AND THEN for possible tracking.
18463 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18464 case of while loops so we can track values in the loop body.
18466 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18467 Hristian Kirtchev <kirtchev@adacore.com>
18468 Bob Duff <duff@adacore.com>
18470 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18471 procedure cannot be a protected operation (it is a basic_declaration,
18472 not a subprogram_declaration).
18473 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18474 Subp. Add logic for entry processing.
18475 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18476 Determine whether an entry or subprogram of a protected or task type
18477 override an inherited primitive of an implemented interface.
18478 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18479 Update the actual used in calls to Check_Overriding_Indicator.
18480 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18481 generate the proper reference to the parent unit, for cross-reference.
18482 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18484 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18485 (Add_Extra_Formal): Revise procedure to allow passing in associated
18486 entity, scope, and name suffix, and handle setting of the new
18487 Extra_Formals field.
18488 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18489 pass new parameters. Add support for adding the new extra access formal
18490 for functions whose calls are treated as build-in-place.
18491 (Analyze_A_Return_Statement): Correct casing in error message.
18492 Move Pop_Scope to after Analyze_Function_Return, because an extended
18493 return statement really is a full-fledged scope. Otherwise, visibility
18494 doesn't work right. Correct use of "\" for continuation messages.
18495 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18496 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18497 the node doesn't get properly marked as analyzed.
18498 (Analyze_Subprogram_Body): If subprogram is a function that returns
18499 an anonymous access type that denotes a task, build a Master Entity
18501 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18502 proper usage of null exclusion in a result definition.
18503 (Process_Formals): Code cleanup and new error message.
18504 (Process_Formals): Detect incorrect application of null exclusion to
18506 (Conforming_Types): Handle conformance between [sub]types and itypes
18507 generated for entities that have null exclusions applied to them.
18508 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18509 base type is an access subtype. This case arrises with null exclusions.
18510 (New_Overloaded_Entity): Do not remove the overriden entity from the
18511 homonym chain if it corresponds with an abstract interface primitive.
18512 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18513 call to the synthesized predicate Is_Incomplete_Type.
18514 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18516 (Analyze_Subprogram_Declaration): Check that abstract interface
18517 primitives are abstract or null.
18518 (Analyze_Subprogram_Specification): Remove previous check for abstract
18519 interfaces because it was not complete.
18520 (Has_Interface_Formals): Removed.

18523 Javier Miranda <miranda@adacore.com>
18525 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18526 of Analyze_Package_Body, to create Itype references for anonymous
18527 access types created in the package declaration, whose designated types
18528 may have only a limited view.
18529 (Analyze_Package_Specification): For the private part of a nested
18530 package, install private_with_clauses of enclosing compilation unit if
18531 we are in its visible part.
18532 (Declare_Inherited_Private_Subprograms): Complete barrier
18533 to ensure that the primitive operation has an alias to some parent
18534 primitive. This is now required because, after the changes done for the
18535 implementation of abstract interfaces, the contents of the list of
18536 primitives has entities whose alias attribute references entities of
18537 such list of primitives.
18538 (Analyze_Package_Specification): Simplify code that handles parent units
18539 of instances and formal packages.
18540 (Uninstall_Declarations): Check the convention consistency among
18541 primitive overriding operations of a tagged record type.

18545 Javier Miranda <miranda@adacore.com>
18546 Ed Schonberg <schonberg@adacore.com>
18548 * sem_ch8.adb: Minor error msg rewording
18549 (Undefined): When checking for misspellings, invert arguments (to get
18550 expected and found set right)
18551 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18552 (Analyze_Generic_Renaming): Same fix
18553 (Use_One_Package): Do not take into account the internal entities of
18554 abstract interfaces during the analysis of entities that are marked
18555 as potentially use-visible.
18556 (Find_Type): Handle the case of an attribute reference for
18557 implementation defined attribute Stub_Type (simply let the analysis of
18558 the attribute reference rewrite it).
18559 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18560 type that appears in a Use_Type clause.
18561 (Analyze_Object_Renaming): Add support for renaming of the Priority
18563 (Find_Type): In Ada 2005, a task type can be used within its own body,
18564 when it appears in an access definition.
18565 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18566 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18567 in a formal object declaration or in a subtype declaration.
18568 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18569 (Check_Null_Exclusion): New local routine to
18570 Analyze_Subprogram_Renaming. Check whether the formals and return
18571 profile of a renamed subprogram have required null exclusions when
18572 their counterparts of the renaming already impose them.
18573 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18574 Determine whether an entity is inside a generic scope.
18575 (In_Open_Scope): First pass of documentation update.
18576 (Find_Expanded_Name): Add support for shadow entities associated with
18577 limited withed packages. This is required to handle nested packages.
18578 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18579 that makes a renaming of a limited withed package illegal.

18582 Ed Schonberg <schonberg@adacore.com>
18584 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18585 Check_Overriding_Indicator.
18586 (Analyze_Task_Definition): Ditto.
18587 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18588 (Check_Overriding_Indicator): To find overridden interface operation,
18589 examine only homonyms that have an explicit subprogram declaration, not
18590 inherited operations created by an unrelated type derivation.
18591 (Check_Overriding_Indicator): When checking for the presence of "null"
18592 in a procedure, ensure that the queried node is a procedure
18594 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18595 type when the formal is an access to variable.
18596 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18597 (Analyze_Task_Type): Same addition
18598 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18599 provide navigation capabilities for entries.

18606 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18607 inherited from an interface ancestor by another interface in the
18608 context of an instance as 'late'.
18609 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18610 of a call to a function that dispatches on access result.
18611 (Check_Dispatching_Operation): In case of late overriding of a primitive
18612 that covers abstract interface subprograms we register it in all the
18613 secondary dispatch tables associated with abstract interfaces.
18614 (Check_Dispatching_Call): Add check that a dispatching call is not made
18615 to a function with a controlling result of a limited type. This is a
18616 current implementation restriction.
18617 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18618 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18619 argument is an interface type that is a generic formal.
18620 (Is_Interface_Subprogram): Removed.
18621 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18622 operation, check the formals to handle the case in which it is
18623 associated with an abstract interface type.
18625 2006-10-31 Robert Dewar <dewar@adacore.com>
18626 Ed Schonberg <schonberg@adacore.com>

18640 Hristian Kirtchev <kirtchev@adacore.com>
18641 Javier Miranda <miranda@adacore.com>
18643 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18644 subprogram type to provide better diagnostics in case of ambiguity.
18645 (Covers): Handle coverage of formal and actual anonymous access types in
18646 the context of generic instantiation.
18647 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18648 abstract interface types; this is required to handle concurrent types
18649 with discriminants and abstract interface types.
18650 (Covers): Include type coverage of both regular incomplete subtypes and
18651 incomplete subtypes of incomplete type visibles through a limited with

18663 Add missing continuation marks in error msgs
18664 (Unqualify): New function for removing zero or more levels of
18665 qualification from an expression. There are numerous places where this
18666 ought to be used, but we currently only deal properly with zero or one
18668 (In_Instance); The analysis of the actuals in the instantiation of a
18669 child unit is not within an instantiation, even though the parent
18670 instance is on the scope stack.
18671 (Safe_To_Capture_Value): Exclude the case of variables that are
18673 (Check_Obsolescent): Removed
18674 (Is_Aliased_View): A reference to an enclosing instance in an aggregate
18675 is an aliased view, even when rewritten as a reference to the target
18676 object in an assignment.
18677 (Get_Subprogram_Entity): New function
18678 (Known_To_Be_Assigned): New function
18679 (Type_Access_Level): Compute properly the access level of a return

18686 has a null exclusion depending on its Nkind.
18687 Change Is_Lvalue to May_Be_Lvalue
18688 (May_Be_Lvalue): Extensive additional code to deal with subprogram
18689 arguments (IN parameters are not Lvalues, IN OUT parameters are).
18690 (Safe_To_Capture_Value): Extend functionality so it can be used for
18691 the current value condition case.
18692 (Has_Compatible_Alignment): New function
18693 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
18694 objects to handle the Ada 2005 case, where aliasedness no longer implies
18695 that the object is constrained. In particular, for dereferenced names,
18696 the designated object must be assumed to be unconstrained.
18697 (Kill_Current_Values): Properly deal with the case where we encounter
18698 a loop in the scope chain.
18699 (Safe_To_Capture_Value): Do not let a loop stop us from capturing
18701 (Compile_Time_Constraint_Error): Improve error message in error case

18709 * s-osinte-tru64.adb:
18710 Mark Asm statements Volatile to prevent warnings (seems a
18711 reasonable change anyway)
18714 * s-mastop-irix.adb: Add Volatile to Asm statements
18715 Suppresses warning, and seems appropriate in any case
18717 * s-osinte-vms.adb: Add Volatile to Asm statement

18731 Private_Extension_Declaration to the list of assertions.
18732 (Is_Entry_Barrier_Function): New flag
18733 (Has_Self_Reference): New flag on aggregates, to indicate that they
18734 contain a reference to the enclosing type, inserted through a default
18736 (Next_Rep_Item): Move from Node4 to Node5.
18737 (Entity): Add this field for N_Attribute_Definition_Clause.
18738 (Comes_From_Extended_Return_Statement): New flag on N_Return_Statement
18739 (N_Return_Object_Declaration): Remove this node kind. We now use
18740 N_Object_Declaration instead.
18741 (Actual_Designated_Subtype): Move to a different place to make room in
18742 N_Extended_Return_Statement.
18743 (Procedure_To_Call): Move to a different place to make room in
18744 N_Extended_Return_Statement.
18745 (Return_Type): Removed this field to make room in return statements
18747 (Return_Statement_Entity): New field in return statements, in part to
18748 replace Return_Type, and in part to support the fact that return
18749 statements are now pushed on the scope stack during semantic analysis.
18750 (Return_Object_Declarations): New field to support extended return
18752 (N_Extended_Return_Statement): New node for extended_return_statement
18754 (N_Return_Object_Declaration): New node for part of
18755 extended_return_statement nonterminal. Needed because all the necessary
18756 fields won't fit in N_Extended_Return_Statement.
18757 Generic_associations now carry the Box_Present flag, to indicate a
18758 default for an actual in a partially parametrized formal package.
18760 * snames.h, snames.ads, snames.adb: Add definition for Validity_Check
18761 (Preset_Names): Add entries for Priority_Specific_Dispatching pragma
18762 and for the new predefined dispatching policies: EDF_Across_Priorities,

18764 Introduce new name Stub_Type for implementation defined attribute.
18765 Add pragma Preelaborable_Initialization

18776 print null exclusion twice in the case of an access definition,
18777 Implement new -gnatL switch
18778 Remove N_Return_Object_Declaration. We now use
18779 N_Object_Declaration instead. Implement the case for
18780 N_Extended_Return_Statement. Alphabetize the cases.
18781 Add cases for new nodes N_Extended_Return_Statement and
18782 N_Return_Object_Declaration. The code is not yet written.
18783 Update the output for N_Formal_Object_Declaration
18784 and N_Object_Renaming_Declaration.
18785 (Write_Itype): Account for the case of a modular integer subtype whose

19360 the pointer to the allocated object to reference the corresponding
19361 secondary dispatch table.
19362 (Expand_N_Op_Divide): Allow 64 bit divisions by small power of 2,
19363 if Long_Shifts are supported on the target, even if 64 bit divides
19364 are not supported (configurable run time mode).
19365 (Expand_N_Type_Conversion): Do validity check if validity checks on
19366 operands are enabled.
19367 (Expand_N_Qualified_Expression): Do validity check if validity checks
19368 on operands are enabled.

19379 the bounds of the type of the discriminant are not static expressions.
19381 * sem_aggr.adb (Check_Static_Discriminated_Subtype): Return false if
19382 the bounds of the discriminant type are not static.
19384 2006-02-17 Robert Dewar <dewar@adacore.com>
19386 * g-os_lib.adb (Copy_File): Make sure that if From has an Invalid_FD,
19387 then we close To if it is valid.
19389 2006-02-17 Vasiliy Fofanov <fofanov@adacore.com>
19391 * init.c (facility_resignal_table): new array
19392 (__gnat_default_resignal_p): enhance default predicate to resignal if
19393 VMS condition has one of the predefined facility codes.

19397 * Makefile.in: Use VMS64 specialized versions of several units in
19398 Interfaces.C hierarchy to be compatible with HP C default size choices.
19399 Use the default version of Ada.Synchronous_Task_Control for VxWorks 653.
19401 2006-02-17 Ed Schonberg <schonberg@adacore.com>
19403 * sem_ch10.adb (Analyze_With_Clause): If the unit is a subprogram
19404 instantiation, the corresponding entity is the related_instance of the

19413 Ed Schonberg <schonberg@adacore.com>
19415 * sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent
19416 type we cannot inherit the primitive operations; we inherit the
19417 Corresponding_Record_Type (which has the list of primitive operations).
19418 (Check_Anonymous_Access_Types): When creating anonymous access types for
19419 access components, use Rewrite in order to preserve the tree structure,
19421 (Analyze_Object_Declaration): For limited types with access
19422 discriminants with defaults initialized by an aggregate, obtain
19423 subtype from aggregate as for other mutable types.
19424 (Derived_Type_Declaration): If the derived type is a limited interface,
19425 set the corresponding flag (Is_Limited_Record is not sufficient).

19434 2006-02-17 Javier Miranda <miranda@adacore.com>
19436 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19437 abstract interface type, the static analysis is not enough to know if
19438 the interface is implemented or not by the source tagged type. Hence
19439 we must pass the work to the expander to generate the required code to
19440 evaluate the conversion at run-time.
19441 (Resolve_Equality_Op): Do not apply previous
19442 transformation if expansion is disasbled, to prevent anomalies when
19443 locating global references in a generic unit.

19623 table to take advantage of the 16 priority levels available on Windows
19624 2000 and XP. On NT4 there are only 7 priority levels, this is properly
19625 supported by this new mapping.

19671 (Read): Change the implementation to support unicode characters. It is
19672 not possible to use strlen() on Windows as this version supports only
19673 standard ASCII characters. So the length of the directory entry is now
19674 returned from the imported __gnat_readdir routine.

19712 E_Floating_Point_Subtype>: Inherit alias set of what we are making a
19713 subtype of to ensure conflicts amongst all subtypes in a hierarchy,
19714 necessary since these are not different types and pointers may
19715 actually designate any subtype in this hierarchy.
19716 (gnat_to_gnu_entity, case E_Record_Type): Always make fields for
19717 discriminants but put them into record only if not Unchecked_Union;
19718 pass flag to components_to_record showing Unchecked_Union.
19719 (make_dummy_type): Use UNION_TYPE only if Unchecked_Union and no
19720 components before variants; don't set TYPE_UNCHECKED_UNION_P.

19722 Remove special case code for Unchecked_Union and instead use main code
19723 with small changes.
19726 (gnat_to_gnu_entity) <E_Variable>: Do not initialize the aligning
19727 variable with the expression being built, only its inner field.

19730 emit_sequence_entry_statements.

19736 (Identifier_to_gnu): Manually unshare the DECL_INITIAL tree when it is
19737 substituted for a CONST_DECL.
19738 (tree_transform, case N_Aggregate): Remove code for UNION_TYPE and pass
19739 Etype to assoc_to_constructor.
19740 (assoc_to_constructor): New argument, GNAT_ENTITY; use it to ignore
19741 discriminants of Unchecked_Union.
19742 (TARGET_ABI_OPEN_VMS): Define to 0 if not defined, so that later uses
19743 don't need cluttering preprocessor directives.
19744 (establish_gnat_vms_condition_handler): New function. Establish the GNAT
19745 condition handler as current in the compiled function.
19746 (body_with_handlers_p): New function. Tell whether a given sequence of
19747 statements node is attached to a package or subprogram body and involves
19748 exception handlers possibly nested within inner block statements.
19749 (emit_sequence_entry_statements): New function, to emit special
19750 statements on entry of sequences when necessary. Establish GNAT
19751 condition handler in the proper cases for VMS.

20252 (Offset_To_Top): The type of the actual has been changed to Address to
20253 give the correct support to tagged types with discriminants. In this
20254 case this value is stored just immediately after the tag field.
20255 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20256 offset_to_top value is static and hence pass this value to the run-time
20257 to store it in the table of interfaces, or else if this value is dynamic
20258 and then pass to the run-time the address of a function that is
20259 generated by the expander to provide this value for each object of the
20262 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20263 (Default_Prim_Op_Count): New entity
20264 (Get_Predefined_Prim_Op_Address): New entity
20265 (Set_Predefined_Prim_Op_Address): New entity
20266 (RE_Set_Signature): New entity

20269 Ed Schonberg <schonberg@adacore.com>
20271 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20272 Make_Adjust_Call done for a newly-allocated object.
20274 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20275 in a subprogram are wrapped in a cleanup block, indicate that the
20276 subprogram contains an inner block with an exception handler.
20277 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20278 Adjust call is for a newly-allocated object. In that case we must not
20279 assume that the finalization list chain pointers are correct (since they
20280 come from a bit-for-bit copy of the original object's pointers) so if
20281 the attach level would otherwise be zero (no change), we set it to 4
20282 instead to cause the pointers to be reset to null.
20284 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20285 reset chain pointers to null.
20287 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20289 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20290 string, and the context requires a loop for the assignment (e.g.
20291 because the left-hand side is packed), generate a unique name for the
20292 temporary that holds the string, to prevent spurious name clashes.
20294 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20295 Javier Miranda <miranda@adacore.com>
20296 Robert Dewar <dewar@adacore.com>
20297 Gary Dismukes <dismukes@adacore.com>
20299 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20300 return unconstrained arrays.
20302 (Expand_Call): An indirect call through an access parameter of a
20303 protected operation is not a protected call.
20304 Add circuit to raise CE in Ada 2005 mode following call
20305 to Raise_Exception.
20306 (Register_DT_Entry): Do nothing if
20307 the run-time does not give support to abstract interfaces.
20308 (Freeze_Subprogram): In case of dispatching operations, do not generate
20309 code to register the operation in the dispatch table if the source
20310 is compiled with No_Dispatching_Calls.
20311 (Register_Predefined_DT_Entry): Generate code that calls the new
20312 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20313 Set_Prim_Op_Address.
20315 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20316 on array assignments if the right-hand side is a function call that has
20317 been inlined. Check is performed on the assignment in the block.
20318 (Process_Bounds): If bounds and range are overloaded, apply preference
20319 rule for root operations to disambiguate, and diagnose true ambiguity.
20320 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20321 a tag-indeterminate right-hand side even when Expander_Active is True.
20322 Needed to ensure that dispatching calls to T'Input are allowed and
20323 get the tag of the target class-wide object.
20325 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20326 an inherited primitive operation that already overrides several
20327 abstract interface primitives. For transitivity, the new entity must
20328 also override all the abstract interface primitives covered by the
20329 inherited overriden primitive.
20330 Emit warning if new entity differs from homograph in same scope only in
20331 that one has an access parameter and the other one has a parameter of
20332 a general access type with the same designated type, at the same
20333 position in the signature.
20334 (Make_Inequality_Operator): Use source locations of parameters and
20335 subtype marks from corresponding equality operator when creating the
20336 tree structure for the implicit declaration of "/=". This does not
20337 change anything in behaviour except that the decoration of the
20338 components of the subtree created for "/=" allows ASIS to get the
20339 string images of the corresponding identifiers.
20340 (Analyze_Return_Statement): Remove '!' in warning message.
20341 (Check_Statement_Sequence): Likewise.
20342 (Analyze_Subprogram_Body): For an access parameter whose designated type
20343 is an incomplete type imported through a limited_with clause, use the
20344 type of the corresponding formal in the body.
20345 (Check_Returns): Implicit return in No_Return procedure now raises
20346 Program_Error with a compile time warning, instead of beging illegal.
20347 (Has_Single_Return): Function returning unconstrained type cannot be
20348 inlined if expression in unique return statement is not an identifier.
20349 (Build_Body_To_Inline): It is possible to inline a function call that
20350 returns an unconstrained type if all return statements in the function
20351 return the same local variable. Subsidiary procedure Has_Single_Return
20352 verifies that the body conforms to this restriction.
20354 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20355 same type, and one of them is of an anonymous access type, convert
20356 the other operand to it, so that this is a valid binary operation for
20358 (Resolve_Type_Conversion): Handle subtypes of protected types and
20359 task types when accessing to the corresponding record type.
20360 (Resolve_Allocator): Add '\' in 2-line warning message.
20361 Remove '!' in warning message.
20362 (Resolve_Call): Add '\' in 2-line warning message.
20363 (Valid_Conversion): Likewise.
20364 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20365 resulting type may be an access type with an implicit dereference.
20366 Obtain the proper component from the designated type.
20367 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20368 given by an expanded name with prefix Standard, when the operands are
20369 of an anonymous access type.
20370 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20371 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20372 prefix of the expression is not of an incomplete type. Allows full
20373 diagnoses of all semantic errors.
20374 (Resolve_Actuals): If the actual is an allocator whose directly
20375 designated type is a class-wide interface we build an anonymous
20376 access type to use it as the type of the allocator. Later, when
20377 the subprogram call is expanded, if the interface has a secondary
20378 dispatch table the expander will add a type conversion to force
20379 the displacement of the pointer.
20380 (Resolve_Call): If a function that returns an unconstrained type is
20381 marked Inlined_Always and inlined, the call will be inlined and does
20382 not require the creation of a transient scope.
20383 (Check_Direct_Boolean_Op): Removed
20384 (Resolve_Comparison_Op): Remove call to above
20385 (Resolve_Equality_Op): Remove call to above
20386 (Resolve_Logical_Op): Inline above, since this is only call.
20387 (Valid_Conversion): Handle properly conversions between arrays of
20388 convertible anonymous access types.
20391 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20392 the literal in an unchecked conversion, because GCC 4.x needs a static
20393 value for a string bound.
20395 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20396 Hristian Kirtchev <kirtchev@adacore.com>
20398 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20399 components of the corresponding record, take into account component
20400 definitions that are access definitions.
20401 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20402 procedure is not considered a dispatching call and will be expanded
20405 2006-02-13 Javier Miranda <miranda@adacore.com>
20407 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20408 controlling argument of the dispatching call is an abstract interface
20409 class-wide type then we use it directly.
20410 Check No_Dispatching_Calls restriction.
20411 (Default_Prim_Op_Position): Remove the code that looks for the last
20412 entity in the list of aliased subprograms. This code was wrong in
20414 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20415 when the source is compiled with the No_Dispatching_Calls restriction.
20416 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20417 if we are compiling with restriction No_Dispatching_Calls.
20418 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20419 subprograms if we are compiling under No_Dispatching_Calls restriction.
20420 (Make_DT): Generate a dispatch table with a single dummy entry if
20421 we are compiling with the No_Dispatching_Calls restriction. In
20422 addition, in this case we don't generate code that calls to the
20423 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20424 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20425 of this subprogram if compiling with the No_Dispatching_Calls
20427 (Expand_Type_Conversion): Instead of using the actual parameter,
20428 the argument passed as parameter to the conversion function was
20429 erroneously referenced by the expander.
20430 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20431 Set_Predefined_Primitive_Op_Address and Set_Signature.
20432 (Expand_Dispatching_Call): Generate call to
20433 Get_Predefined_Prim_Op_Address for predefined primitives.
20434 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20435 predefined primitives.
20436 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20437 primitives we reserve one dummy entry to ensure that the tag does not
20438 point to some memory that is associated with some other object. In
20439 addition, remove all the old code that generated the assignments
20440 associated with the signature of the dispatch table and replace them
20441 by a call to the new subprogram Set_Signature.
20442 (Set_All_DT_Position): Change the algorithm because now we have a
20443 separate dispatch table associated with predefined primitive operations.
20444 (Expand_Interface_Conversion): In case of non-static offset_to_top
20445 add explicit dereference to get access to the object after the call
20446 to displace the pointer to the object.
20447 (Expand_Interface_Thunk): Modify the generation of the actual used
20448 in the calls to the run-time function Offset_To_Top to fulfil its
20450 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20452 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20454 * exp_dist.adb (Copy_Specification): For access parameters, copy
20455 Null_Exclusion flag, which will have been set for stream subprograms
20458 2006-02-13 Pascal Obry <obry@adacore.com>
20460 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20461 previous implementation was using the C runtime spawnve routine but
20462 the corresponding wait was using directly the Win32 API. This was
20463 causing some times a lock when waiting for an event using
20464 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20465 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20466 API fixes this problem.
20468 2006-02-13 Robert Dewar <dewar@adacore.com>
20470 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20478 array reference that is an explicit dereference, mark the converted
20479 (packed) array reference as analyzed to prevent a forthcoming
20480 reanalysis from resetting its type to the original (non-packed) array

20484 Javier Miranda <miranda@adacore.com>
20485 Eric Botcazou <ebotcazou@adacore.com>
20487 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20488 Is_Predefined_Primitive_Operation): When
20489 searching for the predefined equality operator, verify that operands
20490 have the same type.
20491 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20492 for the last entity in the list of aliased subprograms. This code
20493 was wrong in case of renamings.
20494 (Set_Renamed_Subprogram): New procedure
20495 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20496 Exp_Type constant computed when entering this subprogram.

20498 (OK_To_Do_Constant_Replacement): New function
20499 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20500 (Side_Effect_Free): An attribute reference 'Input is not free of
20501 side effect, unlike other attributes that are functions. (from code
20503 (Remove_Side_Effects): Expressions that involve packed arrays or records
20504 are copied at the point of reference, and therefore must be marked as
20505 renamings of objects.
20506 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20507 not a dispatching operation.
20510 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20511 elementary types in all cases.

20516 task types when accessing to the corresponding record type.
20517 Remove '!' in warning message.
20519 2006-02-13 Olivier Hainque <hainque@adacore.com>
20521 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20522 to avoid useless and space inefficient overalignments on targets where
20523 Max_Alignment is larger than 16.
20525 2006-02-13 Pascal Obry <obry@adacore.com>
20527 * g-catiio.adb (Sec_Number): New type used to compute the number of
20528 seconds since 1-1-1970.
20529 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20530 negative numbers (years, months...) it is better to have a Natural here.
20532 (Image) [Number]: Change parameter from Long_Integer to Number.
20533 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20534 overflow for dates past year 2038.
20536 2006-02-13 Matthew Heaney <heaney@adacore.com>
20538 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20541 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20543 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20545 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20546 finalization can occur normally.
20548 2006-02-13 Vincent Celier <celier@adacore.com>
20550 * gnatcmd.adb (Rules_Switches): New table
20551 (Add_To_Rules_Switches): New procedure
20552 (GNATCmd): For command CHECK, put all options following "-rules" in the
20553 Rules_Switches table. Append these -rules switches after the -cargs
20556 2006-02-13 Robert Dewar <dewar@adacore.com>
20558 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20559 These two cases were generating incorrect output, and if this unit
20560 was built with checks on, generated a discriminant mismatch constraint
20563 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20564 Robert Dewar <dewar@adacore.com>
20566 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20567 view is an array type, indicate the component type as well, for
20568 navigation purposes.

20570 of violating pragma Unreferenced.
20571 Do not give Ada 2005 warning except on real reference.

20575 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20576 main source, add switch -mdebug-main=_ada_ so that the executable can
20577 be debugged by the standard VMS debugger.
20578 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20579 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20580 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20581 of the last source, as the binding and linking phases are never
20583 Set all executable obsolete when rebuilding a library.
20585 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20588 2006-02-13 Javier Miranda <miranda@adacore.com>
20591 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20592 code to improve the error message reported when the program has
20593 declarations of abstract interface types and it is not compiled with
20594 the -gnat05 switch.
20595 (P_Access_Definition): Reorganize the code to improve the error
20596 message reported when the new Ada 2005 syntax for anonymous
20597 access types is used and the program is not compiled with the

20637 Prj.Nmsc.Check with parameter When_No_Sources.
20638 (Process): New parameter When_No_Sources. Call Check with parameter

20650 When removing nodes (attributes Source_Dirs, Source_Files,
20651 Source_List_File and package Naming), save the comments and attach the
20652 saved comments to the newly created nodes.
20653 Do not add a with clause for the naming package if one already exists.

20669 No_Return procedure with procedure that is not No_Return
20670 (Check_Dispatching_Call): Suppress the check for an abstract operation
20671 when the original node of an actual is a tag-indeterminate attribute
20672 call, since the attribute, which must be 'Input, can never be abstract.
20673 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20674 call to the Input attribute (even when rewritten).
20675 (Propagate_Tag): Augment comment to indicate the possibility of a call
20676 to an Input attribute.
20678 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20692 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20693 handles default-initialized components to keep separate the management
20694 of this feature but also avoid the unrequired resolution and
20695 expansion of components that do not have partially initialized
20697 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20698 (Check_Bounds): Likewise.
20699 (Check_Length): Likewise.
20701 2006-02-13 Javier Miranda <miranda@adacore.com>
20702 Ed Schonberg <schonberg@adacore.com>
20704 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20705 abstract interface type call analyze_and_resolve to expand the type
20706 conversion into the corresponding displacement of the
20707 reference to the base of the object.
20708 (Eval_Attribute, case Width): For systems where IEEE extended precision
20709 is supported, the maximum exponent occupies 4 decimal digits.
20710 (Accessibility_Message): Add '\' in 2-line warning message.
20711 (Resolve_Attribute): Likewise.
20712 (case Attribute_Access): Significantly revise checks
20713 for illegal access-to-subprogram Access attributes to properly enforce
20714 the rules of 3.10.2(32/2).
20715 Diagnose use of current instance with an illegal attribute.
20717 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20719 (Enclosing_Generic_Unit): New function to return a node's innermost
20720 enclosing generic declaration node.
20721 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20722 (Type_Access_Level): The accessibility level of anonymous acccess types
20723 associated with discriminants is that of the current instance of the
20724 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20725 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20726 (Kill_Current_Values_For_Entity): New function
20727 (Enter_Name): Change formal type to Entity_Id
20729 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>

20731 Gary Dismukes <dismukes@adacore.com>
20733 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20734 Analyze_Compilation_Unit.
20735 Detect and warn on redundant with clauses detected in a package spec
20736 and/or body when -gnatwr is used.
20737 (Analyze_Context): Analyze config pragmas before other items
20738 (Install_Context_Items): Don't analyze config pragmas here
20739 (Install_Limited_Withed_Unit): Set limited entity of package in
20740 with_clause so that cross-reference information or warning messages on
20741 unused packages can be properly generated
20742 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20743 has Error_Posted set. Prevent infinite loops in illegal programs.
20744 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20745 to the point of the error test requiring the current unit to be private.
20746 This ensures that private with clauses are not exempted from the basic
20747 checking for being a descendant of the same library unit parent as a
20748 withed private descendant unit.
20749 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20750 handle private with clauses properly, as well as to account for cases
20751 where the withed unit is a public descendant of a private ancestor
20752 (in which case the current unit must be a descendant of the private
20753 ancestor's parent). The spec comments were updated accordingly. Also,
20754 the old error message in this subprogram was replaced with error
20755 messages that mirror the errors tested and reported by
20756 Check_Private_Child_Unit.
20757 Parameter and variable names improved for readability.
20758 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20759 private as the precondition for calling
20760 Check_Private_Limited_Withed_Unit since that subprogram has been
20761 revised to test public units as well as private units.

20765 Ed Schonberg <schonberg@adacore.com>
20766 Javier Miranda <miranda@adacore.com>
20768 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20769 that Scope_Stack.First = 1.
20770 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20771 were not always properly handled previously.
20772 (Formal_Entity): Complete rewrite, to handle properly some complex case
20773 with multiple levels of parametrization by formal packages.
20774 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20775 to the corresponding derived type declaration for proper semantics.
20777 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20778 (Check_Component): Enforce restriction on components of
20779 unchecked_unions: a component in a variant cannot contain tasks or
20781 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20783 Add pragma Ada_2005 (synonym for Ada_05)
20784 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20785 were not always properly handled previously.
20786 Document that pragma Propagate_Exceptions has no effect
20787 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20788 (Set_Convention_From_Pragma): Check that if a convention is
20789 specified for a dispatching operation, then it must be
20790 consistent with the existing convention for the operation.
20791 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20792 longer required to specify an vtable-ptr component in the record. For
20793 compatibility reasons we leave the support for the previous definition.
20794 (Analyze_Pragma, case No_Return): Allow multiple arguments
20796 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20797 non-overrideen inherited operation with a controlling result as
20798 illegal only its implicit declaration comes from the derived type
20799 declaration of its result's type.
20800 (Check_Possible_Deferred_Completion): Relocate the object definition
20801 node of the subtype indication of a deferred constant completion rather
20802 than directly analyzing it. The analysis of the generated subtype will
20803 correctly decorate the GNAT tree.
20804 (Record_Type_Declaration): Check whether this is a declaration for a
20805 limited derived record before analyzing components.
20806 (Analyze_Component_Declaration): Diagnose record types not explicitly
20807 declared limited when a component has a limited type.
20808 (Build_Derived_Record_Type): Code reorganization to check if some of
20809 the inherited subprograms of a tagged type cover interface primitives.
20810 This check was missing in case of a full-type associated with a private
20812 (Constant_Redeclaration): Check that the subtypes of the partial and the
20813 full view of a constrained deferred constant statically match.
20814 (Mentions_T): A reference to the current type in an anonymous access
20815 component declaration must be an entity name.
20816 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20817 class_wide type to refer to full type, not to the incomplete one.
20818 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20819 available. Required to give support to the certified run-time.
20820 (Analyze_Component_Declaration): In case of anonymous access components
20821 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20822 (Process_Discriminants): For an access discriminant, use the
20823 discriminant specification as the associated_node_for_itype, to
20824 simplify accessibility checks.
20826 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20827 Javier Miranda <miranda@adacore.com>
20829 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20830 abstract interpretations on an operator, remove interpretations that
20831 yield Address or a type derived from it, if one of the operands is an
20833 (Try_Object_Operation.Try_Primitive_Operation,
20834 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20835 location when creating the new reference to a primitive or class-wide
20836 operation as a part of rewriting a subprogram call.
20837 (Try_Primitive_Operations): If context requires a function, collect all
20838 interpretations after the first match, because there may be primitive
20839 operations of the same type with the same profile and different return
20840 types. From code reading.
20841 (Try_Primitive_Operation): Use the node kind to choose the proper
20842 operation when a function and a procedure have the same parameter
20844 (Complete_Object_Operation): If formal is an access parameter and prefix
20845 is an object, rewrite as an Access reference, to match signature of
20846 primitive operation.
20847 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20848 by an expanded name with prefix Standard, when the operands are of an
20849 anonymous access type.
20850 (Remove_Abstract_Operations): If the operation is abstract because it is
20851 inherited by a user-defined type derived from Address, remove it as
20852 well from the set of candidate interpretations of an overloaded node.
20853 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20856 2006-02-13 Bob Duff <duff@adacore.com>
20858 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20859 redundant use clauses.
20860 In particular, if the scope of two use clauses overlaps, but one is not
20861 entirely included in the other, we should not warn. This can happen
20862 with nested packages.
20863 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20864 reported errors. The bug was reported when the compiler was built
20865 with assertions enabled.
20866 (Find_Type): If the node is a 'Class reference and the prefix is a
20867 synchronized type without a corresponding record, return the type
20870 2006-02-13 Javier Miranda <miranda@adacore.com>
20872 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20873 if this is the full-declaration associated with a private declaration
20874 that implement interfaces, then the private type declaration must be
20876 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20877 as aliased. The use of the 'access attribute is not available for such
20878 object (for this purpose the object should be explicitly marked as
20879 aliased, but being an anonymous type this is not possible).
20881 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20882 Robert Dewar <dewar@adacore.com>
20884 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20885 compilation unit is an elaboration scope.
20886 (Add_Task_Proc): Add '\' in 2-line warning message.
20887 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20889 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20890 Javier Miranda <miranda@adacore.com>
20892 * sem_type.adb (Write_Overloads): Improve display of candidate
20894 (Add_One_Interp): Do not add to the list of interpretations aliased
20895 entities corresponding with an abstract interface type that is an
20896 immediate ancestor of a tagged type; otherwise we have a dummy
20897 conflict between this entity and the aliased entity.
20898 (Disambiguate): The predefined equality on universal_access is not
20899 usable if there is a user-defined equality with the proper signature,
20900 declared in the same declarative part as the designated type.
20901 (Find_Unique_Type): The universal_access equality operator defined under
20902 AI-230 does not cover pool specific access types.
20903 (Covers): If one of the types is a generic actual subtype, check whether
20904 it matches the partial view of the other type.
20906 2006-02-13 Thomas Quinot <quinot@adacore.com>
20908 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20909 line. This is necessary to allow In_Extended_Main_Unit to provide
20910 correct results for itypes while writing out expanded source.
20911 (Close_File): No need to update the source_index_table here since it's
20912 now done for each line.
20914 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20915 Robert Dewar <dewar@adacore.com>
20917 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20918 preserve the source unit where the itype is declared, and prevent a
20920 (Note_Implicit_Run_Time_Call): New procedure
20921 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20924 * sprint.ads: Document use of $ for implicit run time routine call
20926 2006-02-13 Quentin Ochem <ochem@adacore.com>
20928 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20931 2006-02-13 Bob Duff <duff@adacore.com>
20933 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20934 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20935 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20936 raise Constraint_Error.
20938 * s-vallli.adb (Scan_Long_Long_Integer): Call
20939 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20940 do not scan leading blanks and sign twice.
20941 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20942 raise Constraint_Error.
20944 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20945 Scan_Long_Long_Unsigned): Split out most of the processing from
20946 Scan_Long_Long_Unsigned out into
20947 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
20948 This prevents scanning leading blanks and sign twice.
20949 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
20952 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
20953 out most of the processing from Scan_Unsigned out into
20954 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
20955 This prevents scanning leading blanks and sign twice.
20957 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
20958 use with Modular'Value attribute.
20959 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
20962 2006-02-13 Robert Dewar <dewar@adacore.com>
20964 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
20966 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
20968 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
20969 (PPC VxWorks): Likewise.
20970 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
20971 (forced_callee): Make non-inlinable and non-pure.
20972 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21088 Ada bind file prefix on VMS from b$ to b__.
21090 * gnatlink.adb (Process_Args): Call Add_Src_Search_Dir for -I in
21091 --GCC so that Get_Target_Parameters can find system.ads.
21092 (Gnatlink): Call Get_Target_Parameters in mainline.
21093 Initialize standard packages for Targparm.
21094 Change some Hostparm.OpenVMS checks to Targparm.OpenVMS_On_Target.

21131 (Target_Object_Suffix): Initialize with target object suffix.
21133 * rident.ads: Add special exception to license.
21135 * targparm.adb (Get_Target_Parameters): Set the value of
21136 Multi_Unit_Index_Character after OpenVMS_On_Target gets its definitive
21138 (Get_Target_Parameters): Set OpenVMS_On_Target if openvms.

21157 * a-taster.ads, a-taster.adb: New files.
21159 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21160 link to the version that does nothing. This way the task termination
21161 routine is not executed twice for the environment task when finishing
21162 because of an unhandled exception.
21164 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21165 handler because of an unhandled exception.
21167 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21168 System.Tasking.Utilities instead of that in System.Tasking.Stages.

21171 finalization of the global list instead of Adafinal.
21173 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21174 non-tasking version of the soft link for task termination. We do
21175 nothing since if we are using the non-tasking version it
21176 means that the task termination functionality is not used.
21177 (Null_Finalize_Global_List): Add this null version for the procedure
21178 in charge of finalizing the global list for controlled objects.
21179 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21180 instead for handling run-time termination in a more flexible way.
21181 (Adafinal_NT): This new procedure will take care of finalizing the
21182 global list for controlled objects if needed, but no tasking
21185 * s-tarest.adb (Task_Lock): Do not try to lock again the
21186 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21187 some run-time operations.
21188 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21189 until all nested locks have been released.
21190 (Task_Wrapper): Call the fall-back task termination handler. It
21191 applies to all tasks but the environment task.
21192 (Finalize_Global_Tasks): Add the call for the task termination
21193 procedure for the environment task.
21194 (Task_Wrapper): suppress warnings around declaration of
21195 Secondary_Stack_Address.
21197 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21198 moved to the Common_ATCB record.
21199 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21200 Common_ATCB record.

21207 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21208 defined in Ada.Task_Termination, to avoid circular dependencies.
21209 (Termination_Handler): Redefine this type here, alredy defined in
21210 Ada.Task_Termination, for avoiding circular dependencies.
21211 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21212 for storing task termination handlers. In addition,
21213 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to

21225 (Finalize_Global_Tasks): Call the task termination procedure for the
21226 environment task. The call to Finalize_Global_List is now performed
21227 using the soft links mechanism.
21228 (Task_Wrapper): added dynamic stack analysis.
21230 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21231 potentially blocking operations has been moved from
21232 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21233 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21234 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21235 this run-time check.

21286 (Displace): New subprogram that displaces the pointer to the object
21287 to reference one of its secondary dispatch tables.
21288 (IW_Membership): Modified to use the new table of interfaces.
21289 (Inherit_TSD): Modified to use the new table of interfaces.

21307 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21308 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21309 record component containing the tag of the secondary dispatch table we
21310 have to use the Offset_To_Top run-time function to get this information;
21311 otherwise if the pointer to the base of the object has been displace
21312 we get a wrong value if we use the 'position attribute.
21314 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21315 all the calls to Expand_Interface_Thunk.
21316 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21320 at the header of the generated list.
21321 (Expand_Interface_Conversion): Handle the case in which the displacement
21322 associated with the interface conversion is not statically known. In

21350 RE_TK_Tagged, RE_TK_Task.
21352 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21353 Init_Secondary_Tags_Internal to allow its use with interface types and
21354 also to generate the code for the new additional actual required
21355 by Set_Offset_To_Top.
21356 (Build_Init_Statements): In case of components associated with abstract
21357 interface types there is no need to generate a call to its IP.

21367 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21368 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21369 properly protected objects and attach handler in the case of the
21370 restricted profile.
21371 Move embeded package Select_Expansion_Utilities into a separate external

21383 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21384 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21385 about the use and expansion of SAVE_EXPRs in the various possible
21386 renaming handling cases.
21387 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21388 abusing DECL_FCONTEXT.

21490 2005-12-09 Robert Dewar <dewar@adacore.com>
21492 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

21556 legal within a protected type that implements an interface.
21557 (Collect_Interfaces): Do not add to the list the interfaces that
21558 are implemented by the ancestors.
21559 (Derived_Type_Declaration): If the parent of the full-view is an
21560 interface perform a transformation of the tree to ensure that it has
21561 the same parent than the partial-view. This simplifies the job of the
21562 expander in order to generate the correct object layout, and it is
21563 needed because the list of interfaces of the full-view can be given in
21565 (Process_Full_View): The parent of the full-view does not need to be
21566 a descendant of the parent of the partial view if both parents are
21568 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21569 "limited" the parent must be a limited type.

21583 (Process_Full_View): Improve the check for the "no hidden interface"
21584 rule as defined by AI-396.
21586 2005-12-09 Robert Dewar <dewar@adacore.com>

21643 available user-specified stream attributes on limited parameters to
21644 also test the type directly rather than only its underlying type (for
21645 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21646 attributes are visible at the point of the subprogram declaration.
21647 For Ada 2005, the error message is modified to indicate that the
21648 type's stream attributes must be visible (again, only for -gnat05).

21905 * gen-soccon.c: Complete value expansion should not be performed on
21906 TARGET, as it has the form of a math expression, and some components
21907 may be platform-defined macros.
21908 For VxWorks, generate the OK and ERROR values.
21909 New constants giving the sizes of the components of C struct timeval.

21921 deal with different cases of static and dynamic elaboration checks (all
21922 checks does not count in the first case, but does in the second).

21928 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21929 elementary types using the operator in standard. It is cleaner not to
21930 modify the programmers intent, especially in the case of floating-point.
21931 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21932 it did not matter because we always rewrote a/=b to not(a=b).
21933 (Expand_Allocator_Expression): For an allocator expression whose nominal
21934 subtype is an unconstrained packed type, convert the expression to its
21935 actual constrained subtype.
21936 Implement warning for <= or >= where < or > not possible
21937 Fix to Vax_Float tests (too early in many routines, causing premature
21938 Vax_Float expansions.
21940 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
21941 to be used with packages and generic packages as well as with

21956 Allow optional = after -gnatm
21957 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
21958 longer sets Elaboration_Checks.
21959 Code to set warning mode moved to Sem_Warn
21960 so that it can be shared by pragma processing.
21962 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
21965 * s-taprop-solaris.adb:
21966 Change some <= to =, to avoid new warning

21972 2005-11-14 Robert Dewar <dewar@adacore.com>
21974 * exp_vfpt.adb: Handle /= case
21975 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag
21976 so that we do not get duplicate scaling for fixed point conversions.
21978 * s-vaflop.ads, s-vaflop.adb: (Ne_F): New function
21980 2005-11-14 Matthew Gingell <gingell@adacore.com>
21982 * system-lynxos-ppc.ads, system-lynxos-x86.ads:
21983 Increase default priority on Lynx from 15 to 17, and meet the Ada
21984 requirement that Default_Priority be ((Priority'First +
21985 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22087 we are not defining the type.
22088 <E_Record_Type>: Likewise.
22089 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22090 to get advantage of the new maybe_stabilize_reference interface, to
22091 ensure that what we reference is indeed stabilized instead of relying
22092 on assumptions on what the stabilizer does.
22093 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22094 type imported through a limited_with clause, use its non-limited view.
22095 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22097 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22098 of #if sections + explicit comparisons of convention identifiers.
22099 (gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
22100 before early-returning for certain types when code generation is
22102 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22103 nullification of gnu_expr we do for objects with address clause and
22104 that we are not defining.
22105 (elaborate_expression_1): Do not create constants when creating
22106 variables needed by the debug info: the dwarf2 writer considers that
22107 CONST_DECLs is used only to represent enumeration constants, and emits
22109 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22110 object with an address clause into an indirect reference, drop the
22111 initializing expression.
22113 (STACK_CHECK_BUILTIN): Delete.
22114 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22122 if there is an actual subtype provided by the front-end, use that
22123 subtype to build an actual type with bounds template.
22124 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22125 is provided by the front-end, use that subtype to compute the size of
22126 the deallocated object.
22127 (gnat_to_gnu): When adding a statement into an elaboration procedure,
22128 check for a potential violation of a No_Elaboration_Code restriction.
22129 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22130 with extra arguments to control whether to recurse through non-values
22131 and to let the caller know if the stabilization has succeeded.

22133 maybe_stabilize, for common uses without restriction on lvalues and
22134 without need to check for the success indication.
22135 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22136 pass false instead of 0 as the FORCE argument which is a bool.
22137 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22138 attached to a renaming pointer has been properly stabilized, as no such
22139 object is attached otherwise.
22140 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22141 function uses the "target pointer" return mechanism.
22142 Reinstate conversion of the actual to the type of the formal
22143 parameter before any other specific treatment based on the passing
22144 mechanism. This turns out to be necessary in order for PLACEHOLDER
22145 substitution to work properly when the latter type is unconstrained.
22147 * gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
22149 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22150 with extra arguments to control whether to recurse through non-values
22151 and to let the caller know if the stabilization has succeeded.
22153 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22154 static output of record constructor if all the components are constant.
22155 (gnat_build_constructor): For a record type, sort the list of field
22156 initializers in increasing bit position order.
22157 Factor common code to build a storage type for an unconstrained object
22158 from a fat or thin pointer type and a constrained object type.
22159 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22160 types variants, and process special cases of VIEW_CONVERT expressions
22161 as their NOP_EXPR counterpart to ensure we get to the
22162 CORRESPONDING_VARs associated with CONST_DECls.
22163 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22164 on the right-hand side.
22166 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
22168 (convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
22169 are converting back to its original type.
22170 (convert) <JM input>: Fallthrough regular conversion code instead of

22368 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22369 'Terminated for task interface class-wide objects. Generate a call to
22370 the predefined dispatching routine used to retrieve the _task_id from

22400 the return value into its actual subtype in order to help the backend

22431 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22451 attribute of the N_Free_Statement.
22452 Generate itype for classwide designated object in both cases of

22648 not install twice the private declarations of the parents, to prevent
22649 circular lists of Use_Clauses in a parent.
22650 (Implicit_With_On_Parent): Do add duplicate with_clause on parent when
22651 compiling body of child unit.
22652 Use new class N_Subprogram_Instantiation
22653 (Expand_With_Clause): If this is a private with_clause for a child unit,
22654 appearing in the context of a package declaration, then the implicit
22655 with_clauses generated for parent units are private as well.

22664 in the actual package.
22665 (Analyze_Formal_Package): Move the setting of the formal package spec's
22666 Generic_Parent field so that it occurs prior to analyzing the package,
22667 to allow proper operation of Install_Parent_Private_Declarations.
22668 (Analyze_Package_Instantiation): Set the instantiated package entity's
22669 Package_Instantiation field.
22670 (Get_Package_Instantiation_Node): Move declaration to package spec.
22671 Retrieve the N_Package_Instantiation node when the Package_Instantiation
22673 (Check_Generic_Child_Unit): Within an inlined call, the only possible
22674 instantiation is Unchecked_Conversion, for which no parents are needed.
22675 (Inline_Instance_Body): Deinstall and record the use_clauses for all
22676 parent scopes of a scope being removed prior to inlining an instance
22678 (Analyze_Package_Instantiation): Do not perform front-end inlining when
22679 the current context is itself an instance within a non-instance child
22680 unit, to prevent scope stack errors.
22681 (Save_References): If the node is an aggregate that is an actual in a
22682 call, rewrite as a qualified expression to preserve some type
22683 information, to resolve possible ambiguities in the instance.
22684 (Instance_Parent_Unit): New global variable to record the ultimate
22685 parent unit associated with a generic child unit instance (associated
22686 with the existing Parent_Unit_Visible flag).

22693 not already set. Replace test of Is_Child_Unit with test of parent's
22694 scope against package Standard. Add comments and a ??? comment.
22695 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
22696 on a child instance parent to test that the parent equals

22711 * sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
22713 (Build_Private_Derived_Type): The entity of the created full view of the
22714 derived type does not come from source. If after installing the private
22715 declarations of the parent scope the parent is still private, use its
22716 full view to construct the full declaration of the derived type.
22717 (Build_Derived_Record_Type): Relax the condition that controls the
22718 execution of the check that verifies that the partial view and
22719 the full view agree in the set of implemented interfaces. In
22720 addition, this test now only takes into account the progenitors.
22721 (Derive_Interface_Subprograms): No need to derive subprograms
22722 of ancestors that are interfaces.

22727 view is a transitive derivation of the ancestor of the partial view.
22728 (Process_Full_View): Rename local subprogram Find_Interface_In_
22729 Descendant to Find_Ancestor_Interface to leave the code more clear.
22730 Remove wrong code that avoids the generation of an error message
22731 when the immediate ancestor of the partial view is an interface.
22732 In addition some minor reorganization of the code has been done to
22733 leave it more clear.
22734 (Analyze_Type_Declaration): If type has previous incomplete tagged
22735 partial view, inherit properly its primitive operations.
22736 (Collect_Interfaces): Make public, for analysis of formal

22745 declared as an access to its own classwide type, to prevent cascaded
22747 (Collect_Interfaces): For private extensions and for derived task types
22748 and derived protected types, the parent may be an interface that must
22749 be included in the interface list.
22750 (Access_Definition): If the designated type is an interface that may
22751 contain tasks, create Master_Id for it before analyzing the expression
22752 of the declaration, which may be an allocator.
22753 (Record_Type_Declaration): Set properly the interface kind, for use
22754 in allocators, the creation of master id's for task interfaces, etc.

22762 appear immediately after a subprogram body, when there is no previous
22763 subprogram declaration.
22764 Change name Is_Package to Is_Package_Or_Generic_Package
22765 (Process_Formals): A non null qualifier on a non null named access
22766 type is not an error, and is a warning only if Redundant_Constructs

22774 declarations and use clauses within each of the parent units of a
22775 package instance of a generic child package.
22776 (Analyze_Package_Specification): When entering a private part of a
22777 package associated with a generic instance or formal package, the
22778 private declarations of the parent must be installed (by calling new
22779 procedure Install_Parent_Private_Declarations).
22780 Change name Is_Package to Is_Package_Or_Generic_Package
22781 (Preserve_Full_Attributes): For a synchronized type, the corresponding
22782 record is absent in a generic context, which does not indicate a

22787 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22788 not try to rewrite a renamed stream attribute, because the operations
22789 on the type may not have been generated.
22790 Handle properly a renaming_as_body generated for a stream operation
22791 whose default is abstract because the object type itself is abstract.
22792 (Find_Type): If the type is incomplete and appears as the prefix of a
22793 'Class reference, it is tagged, and its list of primitive operations
22794 must be initialized properly.
22795 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22796 private declaration of a parent unit, prior to compiling the private
22797 part of a child unit, find on the scope stack the proper parent entity
22798 on which to link the use clause.
22799 (Note_Redundant_Use): Emit a warning when a redundant use clause is
22801 (Analyze_Object_Renaming): An attribute reference is not a legal object

22819 a procedure call is used as a select statement trigger and is not an
22820 entry renaming or a primitive of a limited interface.
22821 (Valid_Conversion): If the operand has a single interpretation do not
22822 remove address operations.
22823 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22824 statement to inhibit warning.
22825 (Resolve_Unary_Op): Do not produce a warning when
22826 processing an expression of the form -(A mod B)
22827 Use Universal_Real instead of Long_Long_Float when we need a high
22828 precision float type for the generated code (prevents gratuitous
22829 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22830 (Resolve_Concatenation_Arg): Improve error message when argument is an
22831 ambiguous call to a function that returns an array.
22832 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
22833 there is an implicit operator in the given scope if we are within an
22834 instance: legality check has been performed on the generic.

23774 * checks.adb (Check_Needed): New procedure, deals with removing checks
23775 based on analysis of short-circuited forms. Also generates warnings for
23776 improper use of non-short-circuited forms.
23779 2005-09-01 Robert Dewar <dewar@adacore.com>
23781 * a-ztexio.adb, a-textio.adb, a-witeio.adb: Replace bad range checks
23784 2005-09-01 Robert Dewar <dewar@adacore.com>
23786 * errout.ads, errout.adb (Fix Error_Msg_F): Fix implementation to meet

23790 (conditional warning).
23791 * sem_elab.adb, prj-dect.adb, erroutc.ads, err_vars.ads
23792 (Error_Msg_Warn): New variable for < insertion char.
23793 * prj-nmsc.adb: Implement new errout insertion char < (conditional
23795 (Check_For_Source): Change value of Source_Id only after the current
23796 source has been dealt with.
23798 2005-09-01 Robert Dewar <dewar@adacore.com>
23799 Doug Rupp <rupp@adacore.com>
23801 * exp_attr.adb: Handle vax fpt for 'Valid attribute

23807 Hristian Kirtchev <kirtchev@adacore.com>
23808 Javier Miranda <miranda@adacore.com>
23810 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23811 from object notation, the original node is unanalyzed and carries no
23812 semantic information, so that accessiblity checks must be performed on
23813 the type of the actual itself.
23814 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23815 compatibility with Build_Protected_Sub_Specification.
23816 (Check_Overriding_Inherited_Interfaces): Add suport to handle
23817 overloaded primitives.
23818 (Register_Interface_DT_Entry): Use the new name of the formal
23819 the the calls to Expand_Interface_Thunk
23821 * exp_dbug.ads: Augment comments on encoding of protected types to
23822 include the generation of dispatching subprograms when the type
23823 implements at least one interface.
23825 * lib.ads: Extend information in Load_Stack to include whether a given
23826 load comes from a Limited_With_Clause.
23828 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23829 whether a potential circularity is harmless, because it includes units
23830 loaded through a limited_with clause. Extends previous treatment which
23831 did not handle properly arbitrary combinations of limited and
23832 non-limited clauses.
23834 2005-09-01 Nicolas Setton <setton@adacore.com>
23836 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23837 to be encoded as typ___XBLU_lowerbound__upperbound instead of
23838 typ___XB_lowerbound__upperbound.
23840 2005-09-01 Thomas Quinot <quinot@adacore.com>
23842 * exp_dist.adb (Add_RACW_TypeCode, Add_RAS_TypeCode): Do not generate
23843 dummy access formal for RACW/RAS TypeCode TSS.
23844 (Build_TypeCode_Call): Do not generate dummy null access actual for
23845 calls to the TypeCode TSS.
23847 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23849 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23850 fully qualified name, to distinguish instances with the same local name.
23852 * g-souinf.ads (Enclosing_Entity): Document that entity name is now
23855 2005-09-01 Robert Dewar <dewar@adacore.com>

23864 (Close): Deallocate any existing filter for the concerned connection
23866 2005-09-01 Laurent Pautet <pautet@adacore.com>
23868 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
23869 position set is provided, we compute one in order to reduce the maximum
23870 length of the keys. This computation first selects a character
23871 position between 1 and the minimum length of the keys in order to
23872 avoid reducing one of the keys to an empty string.
23873 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23874 does not converge. The initialization procedure now comes with a
23875 maximum number of iterations such that when exceeded, an exception is
23876 raised in Compute. The user can initialize this ratio to another value
23878 Reformating and updated headers.
23880 2005-09-01 Javier Miranda <miranda@adacore.com>
23882 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
23883 that given an entity T creates and returns an Itype that duplicates the
23884 contents of T. The returned Itype has the null-exclusion
23885 attribute set to True, and its Etype attribute references T
23886 to keep the association between the two entities.
23887 Update copyright notice
23889 * sem_aggr.adb (Check_Can_Never_Be_Null,
23890 Aggregate_Constraint_Checks, Resolve_Aggregate,
23891 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
23893 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

23896 Robert Dewar <dewar@adacore.com>
23897 Hristian Kirtchev <kirtchev@adacore.com>

23904 Call Set_Result_Definition instead of Set_Subtype_Mark.
23905 (P_Subprogram_Specification): Add parsing of anonymous access result
23906 plus null exclusions. Call Set_Result_Definition instead of
23909 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23910 (P_Access_Type_Definition): Add parsing for an anonymous access result
23911 subtype, plus parsing for null exclusions. Call Set_Result_Definition
23912 instead of Set_Subtype_Mark.
23914 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
23915 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
23916 (Result_Definition): New function for N_Function_Specifications.
23917 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
23918 N_Function_Specification.
23919 (Set_Null_Exclusion_Present): Allow this flag for
23920 N_Function_Specification.
23921 (Set_Result_Definition): New procedure for N_Function_Specifications.
23922 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
23923 and N_Function_Specification.
23925 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
23926 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
23927 Add support for LIMITED NEW for Ada 2005 AI-419
23928 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
23929 syntax for anonymous access results.
23930 Replace Subtype_Mark field by Result_Definition in
23931 N_Function_Specification and N_Access_Definition specs.
23932 Add Null_Exclusion_Present to spec of N_Function_Specification.
23933 (Result_Definition): New function for N_Function_Specification and
23934 N_Access_Function_Definition.
23935 (Set_Result_Definition): New procedure for N_Function_Specification and
23936 N_Access_Function_Definition.
23938 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
23939 Result_Definition for cases of N_Access_Function_Definition and
23940 N_Function_Specification.
23941 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
23943 2005-09-01 Vincent Celier <celier@adacore.com>
23945 * lib-writ.adb: Update Copyright notice
23946 (Write_With_Lines): On platforms where file names are case-insensitive,
23947 record the file names in lower case.
23948 (Write_ALI): For D lines, on platforms where file names are
23949 case-insensitive, record the file names in lower case.
23951 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23952 Emmanuel Briot <briot@adacore.com>
23954 * lib-xref.adb (Output_Overridden_Op): Display information on
23955 overridden operation.
23957 * lib-xref.ads: Add documentation on overridden operations.
23959 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
23962 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
23963 overriding entity information.
23965 2005-09-01 Vincent Celier <celier@adacore.com>
23967 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
23968 including those that are inherited.
23970 2005-09-01 Robert Dewar <dewar@adacore.com>
23972 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
23974 * par-prag.adb: Implement new pragma Debug_Policy
23976 * sem_prag.adb Implement new pragma Debug_Policy
23977 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
23978 Component_Size attribute specification. Give warning for ignored pragma
23981 * snames.h, snames.ads, snames.adb: Introduce entries in
23982 Preset_Names for Name_Disp_Asynchronous_Select,
23983 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
23984 Name_Disp_Timed_Select.
23985 New pragma Debug_Policy
23987 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
23989 Switch -gnata also sets Debug_Pragmas_Enabled
23991 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
23992 handle an explicit -gnata when compiling predefined files.
23994 2005-09-01 Vincent Celier <celier@adacore.com>
23996 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23997 directories of projects that have no Ada sources.
23999 2005-09-01 Robert Dewar <dewar@adacore.com>
24001 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24002 (makes a difference for wide characters)
24004 * widechar.adb, widechar.ads:
24005 Add Wide_Char_Byte_Count feature to count chars vs bytes
24007 2005-09-01 Thomas Quinot <quinot@adacore.com>
24008 Ed Schonberg <schonberg@adacore.com>
24009 Robert Dewar <dewar@adacore.com>
24011 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24012 'Address attribute reference with an overloaded prefix, use the
24013 location of the prefix (not the location of the attribute reference) as
24014 the error location.
24015 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24016 a function renaming thereof, is a valid prefix for 'Size (where it is
24017 intepreted as a function call).
24018 (Statically_Denotes_Entity): New predicate to determine whether the
24019 prefix of an array attribute can be considered static.
24022 (Eval_Attr): Fix failure to evaluate Component_Size for
24023 unconstrained arrays (resulted in wrong value in packed case, since
24024 back end cannot handle this case)
24026 2005-09-01 Robert Dewar <dewar@adacore.com>
24028 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24029 error msgs for most common cases.
24030 Use new errout insertion char < (conditional warning)
24032 2005-09-01 Javier Miranda <miranda@adacore.com>
24033 Ed Schonberg <schonberg@adacore.com>
24035 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24036 become local to the whole package.
24037 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24038 the package was already analyzed the new algorithm "replaces" the
24039 real entities by the shadow ones. This is required to ensure that
24040 the order of these entities in the homonym chains does not change;
24041 otherwise we can have undefined references at linking time because
24042 in case of conflicts the external name of the entities will have
24043 a suffix that depends on the order of the entities in the chain.
24044 (Remove_Limited_With_Clause): Complementary code that completes the
24045 new algorithm and replaces the shadow entities by the real ones.
24046 (Install_Limited_Withed_Unit): When unchaining entities before the
24047 installation of the shadow entities, only regular entities of the
24048 public part must be taken into account. This is required to
24049 keep this routine in synch with the work done by Remove_Limited_
24051 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24052 even if unit is analyzed, because the analysis of the unit is
24053 idempotent in any case, and the limited view of the unit may have to
24054 be installed for proper visibility.
24055 (Expand_Limited_With_Clause): Even if the unit in the implicit
24056 with_clause has been analyzed already, a limited view of the package
24057 must be built for the current context, if it does not exist yet.
24059 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24060 Javier Miranda <miranda@adacore.com>
24061 Gary Dismukes <dismukes@adacore.com>
24063 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24064 defining entity for the instance body, make a new defining identifier
24065 rather than copying the entity of the spec, to prevent accidental
24066 sharing of the entity list.
24067 (Check_Private_View): When exchanging views of private types, build the
24068 list of exchanged views as a stack, to ensure that on exit the exchanges
24069 are undone in the proper order.
24070 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24071 Restore the compilation environment in case of instantiation_error.
24072 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24073 for an anonymous access result.
24074 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24075 (Formal_Entity): Handle properly the case of a formal package that
24076 denotes a generic package renaming.
24078 2005-09-01 Thomas Quinot <quinot@adacore.com>
24080 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24081 clause if the array aggregate is surrounded by parentheses.
24083 2005-09-01 Cyrille Comar <comar@adacore.com>
24084 Gary Dismukes <dismukes@adacore.com>
24085 Ed Schonberg <schonberg@adacore.com>
24086 Javier Miranda <miranda@adacore.com>
24088 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24090 to check if a type is Constrained in cases related to code generation
24091 (rather than semantic checking) since otherwise we do not generate
24092 similar code for mutable private types depending if their
24093 discriminants are visible or not.
24094 (Check_Abstract_Overriding): Do not complain about failure to override
24095 the primitive operations used in dispatching selects since they will
24096 always be overriden at the freeze point of the type.
24097 (Access_Definition): Separate out handling for resetting the scope
24098 of an anonymous access function result type. Retrieve the scope
24099 of the associated function rather than using Current_Scope, which
24100 does not have a consistent value (depends on whether we're in the
24101 middle of analyzing formal parameters). Add ??? comment about
24102 finding a cleaner way to handle the special cases of scope setting.
24103 (Process_Incomplete_Dependents): A protected operation is never a
24104 dispatching operation (only its wrapper may be).
24105 (Build_Derived_Record_Type): In case of tagged private types that
24106 implement interfaces add derivation of predefined primitive
24108 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24109 by two parameters that are used in case of derivation from abstract
24110 interface types: No_Predefined_Prims is used to avoid the derivation
24111 of predefined primitives from the interface, and Predefined
24112 Prims_Only is used to complete the derivation predefined primitives
24113 in case of private tagged types implementing interfaces.
24114 Fix typo in comments
24115 (Find_Interface_In_Descendant): Protect the frontend against
24116 wrong code with large circularity chains.
24117 (Is_Private_Overriding): Add support for entities overriding interface
24118 subprograms. The test failed because Entities associated with overriden
24119 interface subprograms are always marked as hidden (and used to build
24120 the secondary dispatch table); in this case the overriden entity is
24121 available through the field abstract_interface_alias (cf. override_
24122 dispatching_operation)
24123 (Access_Definition): Set the scope of the type to Current_Scope for the
24124 case of a function with an anonymous access result type.
24125 (Access_Subprogram_Declaration): Handle creation of the type entity for
24126 an access-to-function type with an anonymous access result.
24127 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24128 in handling for N_Access_Function_Definition.
24129 (Analyze_Subtype_Declaration): Modify the text of error message.
24130 (Derived_Type_Declaration): Modify the text of error message.
24131 (Process_Subtype): Modify the text of error message plus cleanup
24132 of one redundant error message.
24133 (Analyze_Component_Declaration): Code cleanup.
24134 (Analyze_Object_Declaration): Code cleanup.
24135 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24136 attribute in case of access types. Code cleanup.
24137 (Array_Type_Declaration): Code cleanup.
24138 (Process_Discriminants): Create the new null-excluding itype
24139 if required. Code cleanup.
24140 (Process_Subtype): Create the new null-excluding itype if
24141 required. Code cleanup.
24142 (Build_Derived_Record_Type): Code cleanup to avoid calling
24143 twice the subprogram derive_subprograms in case of private
24144 types that implement interfaces. In this particular case the
24145 subprogram Complete_Subprograms_Derivation already does the
24146 job associated with the second call.
24148 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24149 conversion to the full view when generating an operation for a
24150 discriminant whose type may currently be private.
24152 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24153 Javier Miranda <miranda@adacore.com>
24155 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24156 V (Obj.F), the rewriting does not involve the indexed component, but
24157 only the selected component itself.
24158 Do not apply the transformation if the analyzed node is an actual of a
24159 call to another subprogram.
24160 (Complete_Object_Operation): Retain the entity of the
24161 dispatching operation in the selector of the rewritten node. The
24162 entity will be used in the expansion of dispatching selects.
24163 (Analyze_One_Call): Improve location of the error message associated
24165 (Analyze_Selected_Component): No need to resolve prefix when it is a
24166 function call, resolution is done when parent node is resolved, as
24168 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24169 when attempting to resolve a call transformed from its object notation.
24170 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24171 of the argument list for each interpretation of the operation.
24172 (Try_Object_Operation): The designated type of an access parameter may
24173 be an incomplete type obtained through a limited_with clause, in which
24174 case the primitive operations of the type are retrieved from its full
24176 (Analyze_Call): If this is an indirect call, and the return type of the
24177 access_to_subprogram is incomplete, use its full view if available.
24179 2005-09-01 Javier Miranda <miranda@adacore.com>
24180 Gary Dismukes <dismukes@adacore.com>
24182 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24183 access types the null-exclusion and access-to-constant attributes must
24185 (Analyze_Return_Statement): When the result type is an anonymous access
24186 type, apply a conversion of the return expression to the access type
24187 to ensure that appropriate accessibility checks are performed.
24188 (Analyze_Return_Type): For the case of an anonymous access result type,
24189 generate the Itype and set Is_Local_Anonymous_Access on the type.
24190 Add ??? placeholder for check to disallow returning a limited object
24191 in Ada 2005 unless it's an aggregate or a result of a function call.
24192 Change calls from Subtype_Mark to Result_Definition.
24193 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24194 Result_Definition in call to Make_Function_Specification.
24195 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24196 Set_Result_Definition.
24197 (Make_Inequality_Operator): Change formal Subtype_Mark to
24198 Result_Definition in call to Make_Function_Specification.
24199 (Process_Formals): Create the new null-excluding itype if required.
24200 (New_Overloaded_Entity): For an entity overriding an interface primitive
24201 check if the entity also covers other abstract subprograms in the same
24202 scope. This is required to handle the general case, that is, overriding
24203 other interface primitives and overriding abstract subprograms inherited
24204 from some abstract ancestor type.
24205 (New_Overloaded_Entity): For an overriding entity that comes from
24206 source, note the operation that it overrides.
24207 (Check_Conformance, Type_Conformant): Addition of one new formal
24208 to skip controlling formals in the analysis. This is used to
24209 handle overloading of abstract interfaces.
24210 (Base_Types_Match): Add missing case for types imported from
24211 limited-with clauses
24212 (New_Overloaded_Entity): Add barrier to protect the use of
24213 the "alias" attribute.
24215 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24217 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24218 verify that the procedure and the entry are mode conformant.
24219 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24220 as a different operator, which is often a cut-and-paste error.
24222 2005-09-01 Javier Miranda <miranda@adacore.com>
24223 Ed Schonberg <schonberg@adacore.com>
24225 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24226 used in controlling parameters exclude null because it is necessary to
24227 read the tag to dispatch, and null has no tag.
24228 (Override_Dispatching_Operation): If the previous operation is inherited
24229 from an interface, it becomes hidden and does not participate in later

24233 Ed Schonberg <schonberg@adacore.com>
24234 Gary Dismukes <dismukes@adacore.com>
24236 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24237 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24238 the expander will generate the corresponding run-time check to evaluate
24240 (Resolve_Call): Check for legal type of procedure name or prefix that
24241 appears as a trigger in a triggering alternative.
24242 (Valid_Conversion): If expression is ambiguous and the context involves
24243 an extension of System, remove System.Address interpretations.
24244 (Resolve_Qualified_Expression): Reject the case of a specific-type
24245 qualification applied to a class-wide argument. Enhance comment
24246 to explain checking of Original_Node.
24247 (Resolve_Type_Conversion): The location of the error message was not
24248 general enough to handle the general case and hence it has been removed.
24249 In addition, this patch improves the text of the message.
24250 (Resolve_Type_Conversion): Add missing support for access to interface
24252 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24253 do not expand if the expression is the actual in a call, because proper
24254 expansion will take place when the call itself is expanded.
24255 (Resolve_Allocator): If the context is an unchecked conversion, the
24256 allocator inherits its storage pool, if any, from the target type of

24260 Javier Miranda <miranda@adacore.com>
24262 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24263 inherited interface operation that has an implementation, use the
24264 implementation to avoid spurious ambiguities.
24265 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24266 use the Corresponding_Record_Typ attribute to look for the interface
24267 because it is set by the expander (and hence it is not always
24268 available). For this reason we traverse the list of interfaces
24269 (available in the parent of the concurrent type).
24270 (Interface_Present_In_Ancestor): Handle entities from the limited view
24272 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24274 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24275 from the list of required components.

24277 primitive procedure of a limited interface with a controlling first
24279 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24281 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24282 capture if it is generated in the second operand of a short-circuit
24284 Do not capture values for variables with address clauses.
24285 (Is_Object_Reference): Treat a function call as an object reference only
24286 if its type is not Standard_Void_Type.
24288 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24290 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24291 to a variable that is statically known to be constant.

25073 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25074 longer protected objects. They have been replaced by lower-level
25075 suspension objects made up by a mutex and a condition variable (or
25076 their equivalent given a particular OS) plus some internal data to
25077 reflect the state of the suspension object.
25078 (Initialize, Finalize): Add this initialization procedure for
25079 Suspension_Object, which is a controlled type.

25107 (Suspend_Until_True): Add this procedure that blocks the calling task
25108 until the state of the object is True. Program_Error is raised if
25109 another task is already waiting on that suspension object.
25110 (Initialize): Add this procedure for initializing the suspension
25111 object. It initializes the mutex and the condition variable which are
25112 used for synchronization and queuing, and it sets the internal state
25114 (Finalize): Add this procedure for finalizing the suspension object,
25115 destroying the mutex and the condition variable.

25454 misaligned because of packing or representation clauses.
25455 (Is_Legal_Copy): New predicate to determine whether a possibly
25456 misaligned in-out actual can actually be passed by copy/return. This

25458 the consequence of a DEC import pragma on the subprogram.
25459 (Expand_Call, Freeze_Subprogram): Modified to give support to abstract
25461 (Expand_Inlined_Call): Mark temporary generated for the return value as

25483 * i-cpp.ads, i-cpp.adb:
25484 This package has been left available for compatibility with previous

25529 (Analyze_Subprogram_Body): Undo the previous work.
25530 (Analyze_Procedure_Call): If the call has the form Object.Op, the
25531 analysis of the prefix ends up analyzing the call itself, after which

25534 subprogram_specification that returns true if some non
25535 class-wide interface subprogram is found
25536 (New_Overloaded_Entity): Modified to give support to abstract
25538 (Conforming_Types): In Ada 2005 mode, conformance checking of anonymous
25539 access to subprograms must be recursive.
25540 (Is_Unchecked_Conversion): Improve the test that recognizes
25541 instantiations of Unchecked_Conversion, and allows them in bodies that
25542 are to be inlined by the front-end. When the body comes from an

25565 object or component (that is, when Is_Local_Anonymous_Access is true).
25566 Prevent the special checks for conversions of access discriminants in
25567 the case where the discriminant belongs to a nonlimited type, since
25568 such discriminants have their accessibility level defined in the same
25569 way as a normal component of an anonymous access type.
25570 (Resolve_Allocator): When an allocator's designated type is a class-wide
25571 type, check that the accessibility level of type given in the
25572 allocator's expression or subtype indication is not statically deeper
25573 than the level of the allocator's access type.

25589 pragma Restrictions (No_Obsolescent_Features).
25590 (Check_Direct_Boolean_Operator): If the boolean operation has been
25591 constant-folded, there is nothing to check.
25592 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25593 check on possible violation of restriction No_Direct_Boolean_Operators
25594 until after expansion of operands, to prevent spurious errors when

25876 subtraction, which would raise an exception on a compiler built with
25877 assertions when the upper bound is Integer'first.
25878 (Flatten): For an array of composite components, take into account the
25879 size of the components to determine whether it is safe to expand the

25894 Ed Schonberg <schonberg@adacore.com>
25896 * exp_dbug.ads, exp_dbug.adb (Get_Variant_Part): Fix the encoding of
25897 the "simple_choice" member in a variant record, in accordance with the
25898 description in the package spec: the information output for a constant
25899 should be "S number", not "SS number".
25900 (Get_Encoded_Name): Return at once if not generating code. Avoids name
25901 overflow problem when compiling with -gnatct, for ASIS/gnatmetrics.

25957 failure of our own connect(2) call.
25958 (Check_Selector): Improve documentation of the selector mechanism.
25959 (Broadcast_Inet_Addr): New constant.

25966 of the type is declared in a record (for determination of insertion
25968 (SO_Ref_From_Expr): Test whether Vtype denotes a partial or full view of

25988 unit as a consequence of parsing a limited-with clause. This is used
25989 to avoid the circularity check.

25992 (Analyze_Context): Limited-with clauses are now allowed
25993 in more compilation units.

25995 againts previously reported critical errors in context clauses
25996 (Install_Limited_Withed_Unit): Code cleanup plus static detection
25997 of two further errors: renamed subprograms and renamed packages

26017 (Get_Type_Reference): For a subtype that is the renaming of an actual in
26018 an instantiation, use the first_subtype to ensure that we don't generate

26599 * exp_dist.adb (Add_RAST_Features, PolyORB version): Set the From_Any,
26600 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26601 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26602 analyzed if expansion is disabled (which could otherwise cause spurious
26603 error messages if expansion has been disabled due to previous
26604 (unrelated) errors).
26606 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26607 is disabled, the entity denoted by the argument is the access type
26608 itself, not an underlying record type, so there is no need to go back
26609 to the Corresponding_Remote_Type.
26611 2005-03-29 Gary Dismukes <dismukes@adacore.com>
26612 Robert Dewar <dewar@adacore.com>

26615 expand a call to an instance of
26616 Ada.Tags.Generic_Dispatching_Constructor into a dispatching call to the
26617 Constructor actual of the instance. A class-wide membership
26618 check is also generated, to ensure that the tag passed to the instance
26619 denotes a type in the class.
26620 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26621 of Name_Generic_Dispatching_Constructor.
26623 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26624 05 unit for AI-260-02).

26638 the case of renaming of stream attributes when the renaming denotes a
26639 generic formal subprogram association for an abstract formal subprogram.
26640 Check that the attribute is a primitive stream attribute (and not
26641 a class-wide stream attribute) and then rewrite the attribute name
26642 as the name of the appropriate compiler-generated stream primitive.
26644 2005-03-29 Robert Dewar <dewar@adacore.com>
26646 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26653 * freeze.adb (Freeze_Record_Type): If the type of the component is an
26654 itype whose parent is controlled and not yet frozen, do not create a
26655 freeze node for the itype if expansion is disabled.
26657 2005-03-29 Vincent Celier <celier@adacore.com>
26659 * make.adb (Gnatmake): Don't fail if the main project file is declared
26660 as having no Ada sources. Do not display message "no sources to
26661 compile" in quiet output.
26663 2005-03-29 Doug Rupp <rupp@adacore.com>
26665 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26676 missing TYPE Improve the error message generated when compiling a
26677 limited interface in Ada83 or Ada95 mode.
26679 2005-03-29 Robert Dewar <dewar@adacore.com>
26681 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26682 rather than proceed ahead using a junk attribute name.
26684 2005-03-29 Vincent Celier <celier@adacore.com>
26686 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26688 * prj-part.adb (Parse_Single_Project): Set the location of a project
26689 on its defining identifier, rather than on the reserved word "project".
26691 * prj-proc.adb (Expression): Adapt to the fact that default of external
26692 references may be string expressions, not always literal strings.
26693 (Recursive_Process): Set Display_Name equal to Name
26694 when Location is No_Location, that is when there is no actual file.
26695 Get the Display_Name of the project from the source, when it is not a
26697 (Process): Use the Display_Name in error messages
26699 * prj-strt.adb (External_Reference): Allow default to be string
26700 expressions, not only literal strings.
26702 2005-03-29 Vincent Celier <celier@adacore.com>
26704 * prj-nmsc.adb (Check_Stand_Alone_Library): Do not forbid the symbol
26705 file and the reference symbol file to be the same file.

26709 * sem_cat.adb (Validate_Remote_Types_Type_Conversion): Perform check to
26710 forbid conversion of a local access-to-subprogram type to a remote one.
26712 * sem_util.adb (Wrong_Type): For a record type that is the expanded
26713 equivalent type for a remote access-to-subprogram type, go back to the
26714 original RAS entity when displaying an error message, so the casing is
26715 the original source casing.
26717 2005-03-29 Robert Dewar <dewar@adacore.com>
26719 * sem_ch11.adb (Analyze_Raise_Statement): Change message for warning
26722 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26724 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
26725 subtype if code is being pre-analyzed, to prevent un-expanded
26726 references to protected formals, among others.
26727 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
26728 interpretation that can be a call, include the result of the call as a
26729 possible interpretation of the dereference.
26731 * sem_ch5.adb (Process_Bounds): Determine type of range by
26732 pre-analyzing a copy of the original range, and then analyze the range
26733 with the expected type.
26735 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
26736 with an overloaded prefix where not all interpretations yield an
26737 access to subprogram, do not rewrite node as a call.
26738 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
26739 the node as a call once the context identifies the interpretation of
26740 the prefix whose call yields the context type.
26741 (Valid_Conversion): For the case of a conversion between
26742 local access-to-subprogram types, check subtype conformance using
26743 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more
26744 detailed error message.
26746 2005-03-29 Ed Schonberg <schonberg@adacore.com>
26748 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
26749 indicator, indicate that the formal can never be null.
26750 (Process_Formals): If a formal has a non_null indicator, insert the
26751 resulting subtype immediately before the enclosing subprogram decl,
26752 and not at the beginning of the corresponding declarative part, to
26753 prevent access before elaboration (Ada2005).

27329 * a-swunau.ads, a-swunau.adb: New interface for Get_Wide_String
27331 * a-szunau.ads, a-szunau.adb: New interface for Get_Wide_Wide_String
27333 2005-03-15 Javier Miranda <miranda@adacore.com>
27334 Robert Dewar <dewar@adacore.com>
27335 Thomas Quinot <quinot@adacore.com>
27336 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27338 * atree.ads, atree.adb: Add support for Elist24 field
27340 * atree.h: Fix wrong definition of Field27
27341 Add support for Elist16 field
27342 Add support for Elist24 field
27344 * einfo.ads, einfo.adb (Abstract_Interfaces,
27345 Set_Abstract_Interfaces): New subprograms.
27346 (Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
27348 (Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
27349 entities rather than a single node.

27356 (Task_Body_Procedure): New subprogram to read this attribute.
27357 (Set_Task_Body_Procedure): New subprogram to set this attribute.
27358 (Has_Controlled_Component): Now applies to all entities.
27359 This is only a documentation change, since it always worked to apply
27360 this to other than composite types (yielding false), but now this is
27362 Update documentation on Must_Be_Byte_Aligned for new spec
27364 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27365 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27366 uses of the Access_Disp_Table attribute to reference the first dispatch
27367 table associated with a tagged type. As
27368 part of the implementation of abstract interface types,
27369 Access_Disp_Table has been redefined to contain a list of dispatch
27370 tables (rather than a single dispatch table).
27371 Similarly, upgrade all the references to Tag_Component by the
27372 new attribute First_Tag_Component.
27373 (Find_Inherited_TSS): Moved to exp_tss.
27374 Clean up test in Expand_N_Object_Declaration for cases
27375 where we need to do a separate assignment of the initial value.
27376 (Expand_N_Object_Declaration): If the expression in the
27377 declaration of a tagged type is an aggregate, no need to generate an
27378 additional tag assignment.
27379 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27381 Bit packed array ops are only called if operands are known to be
27383 (Component_Equality): When returning an N_Raise_Program_Error statement,
27384 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27385 expects that only expressions have a bona fide type).
27386 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27387 determine the amount of data to be copied.
27389 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27390 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
27391 INTERFACE_TYPE_DEFINITION ::=
27392 [limited | task | protected | synchronized] interface
27393 [AND interface_list]
27395 * par-ch3.adb (P_Type_Declaration): Modified to give support to
27397 (P_Derived_Type_Def_Or_Private_Ext_Decl): Modified to give support to
27399 (P_Interface_Type_Definition): New subprogram that parses the new
27400 syntax rule of Ada 2005 interfaces
27401 (P_Identifier_Declarations): fix two occurrences of 'RENAMES' in error
27402 messages by the correct RENAMES (quotes removed).
27404 * sem_prag.adb: Upgrade all the references to Tag_Component by the new
27405 attribute First_Tag_Component.
27407 * sinfo.ads, sinfo.adb: Remove OK_For_Stream flag, not used, not needed
27408 (Interface_List, Set_Interface_List): New subprograms.
27409 (Interface_Present, Set_Interface_Present): New subprograms.
27410 (Limited_Present, Set_Limited_Present): Available also in derived
27411 type definition nodes.
27412 (Protected_Present, Set_Protected_Present): Available also in
27413 record type definition and
27414 derived type definition nodes.
27415 (Synchronized_Present, Set_Synchronized_Present): New subprograms.
27416 (Task_Present, Set_Task_Present): New subprogram.
27417 (Task_Body_Procedure): Removed.
27418 (Set_Task_Body_Procedure): Removed.
27419 These subprogram have been removed because the attribute
27420 Task_Body_Procedure has been moved to the corresponding task type
27421 or task subtype entity to leave a field free to store the list
27422 of interfaces implemented by a task (for AI-345)
27423 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27424 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27425 expression flag Do_Range_Check
27426 (Exception_Junk): Change to Flag7 to accomodate above change
27427 (Box_Present, Default_Name, Specification, Set_Box_Present,
27428 Set_Default_Name, Set_Specification): Expand the expression
27429 "X in N_Formal_Subprogram_Declaration" into the corresponding
27430 two comparisons. Required to use the csinfo tool.
27432 * exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
27433 "with string" given.
27435 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27438 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27441 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27442 attribute Task_Body_Procedure rather than the old semantic field that
27443 was available in the task_type_declaration node.
27445 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27446 interface type definitions.
27447 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27450 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27451 task type declaration.
27452 (P_Protected): Modified to handle the list of interfaces in a
27453 protected type declaration.
27455 2005-03-15 Doug Rupp <rupp@adacore.com>
27456 Vincent Celier <celier@adacore.com>
27458 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27459 (Gen_Output_File_C): Likewise.
27460 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27462 2005-03-15 Thomas Quinot <quinot@adacore.com>
27464 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27465 is an N_Raise_Constraint_Error node, create a new copy of it without
27466 going through a call to Duplicate_Subexpr.
27468 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27469 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27470 Nicolas Setton <setton@adacore.com>
27471 Ed Schonberg <schonberg@adacore.com>
27477 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27478 representation clause that prescribes a size not equal to the rounded
27479 size of their types.
27480 (gnat_to_gnu_entity, case E_Component): Always look at
27481 Original_Record_Component if Present and not the entity.
27482 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27483 of tagged extension types by not making field for components that are
27485 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27486 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27487 expression to the type of the object when the object is constant.
27488 Reverse defer_debug_incomplete_list before traversing it, so that trees
27489 are processed in the order at which they were added to the list. This
27490 order is important when using the stabs debug format.
27491 If we are deferring the output of debug information, also defer this
27492 output for a function return type.
27493 When adding fields to a record, prevent emitting debug information
27494 for incomplete records, emit the information only when the record is
27496 (components_to_record): New parameter defer_debug.
27497 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27498 (gnat_to_gnu_field_decl): New function.
27499 (substitution_list, annotate_rep): Call it.
27500 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27501 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27502 No longer update discriminants to not be a COMPONENT_REF.
27503 (copy_alias_set): Strip padding from input type; also handle
27504 unconstrained arrays properly.
27506 * gigi.h (write_record_type_debug_info): New function.
27507 Convert to use ANSI-style prototypes. Remove unused
27508 declarations for emit_stack_check, elab_all_gnat and
27509 set_second_error_entity.
27510 (gnat_to_gnu_field_decl): New decl.
27512 * utils.c (write_record_type_debug_info): New function.
27513 (finish_record_type): Delegate generation of debug information to
27514 write_record_type_debug_info.
27515 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27516 (update_pointer_to): Fix pasto.
27517 (convert) <UNION_TYPE>: Accept slight type variations when
27518 converting to an unchecked union type.
27520 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27521 replace the N_Freeze_Entity with a null statement.
27523 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27524 within a constrained subcomponent of an enclosing record, place the
27525 freeze nodes in the scope stack entry for the enclosing record.
27526 (Undelay_Type): New Subprogram.
27527 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27528 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27529 within records; allow them to have freeze nodes if their base types
27532 * exp_util.adb (Remove_Side_Effects): Properly test for
27533 Expansion_Delayed and handle case when it's inside an
27534 N_Qualified_Expression.
27536 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27537 Comes_From_Generic, to recognize accurately that the parent type in a
27538 derived type declaration can be traced back to a formal type, because
27539 it is one or is derived from one, or because its completion is derived
27541 (Constrain_Component_Type): If component comes from source and has no
27542 explicit constraint, no need to constrain in in a subtype of the
27544 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27545 Minor change to propagate Is_Ada_2005 flag
27547 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27548 Expansion_Delayed is False.
27549 (assoc_to_constructor): Ignore fields that have a
27550 Corresponding_Discriminant.
27551 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27552 function returns "by target", dereference the target pointer using the
27553 type of the actual return value.
27554 <all>: Be prepared for a null gnu_result.
27555 (processed_inline_subprograms): Check flag_really_no_inline
27556 instead of flag_no_inline.
27557 (set_second_error_entity): Remove unused function.

27562 2005-03-15 Robert Dewar <dewar@adacore.com>
27563 Ed Schonberg <schonberg@adacore.com>
27564 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27566 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27567 Must_Be_Byte_Aligned for cases where we do not need to use a
27568 System.Pack_nn unit.
27570 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27572 Needed now that we do some processing for IN parameters as well. This
27573 may well fix some unrelated errors.
27574 (Expand_Call): Handle case of unaligned objects (in particular those
27575 that come from packed arrays).
27576 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27577 renamed entity is an inherited operation, re-expand the call using the
27578 original operation, which is the one to call.
27579 Detect attempt to inline parameterless recursive subprogram.
27580 (Represented_As_Scalar): Fix to work properly with private types
27581 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27582 accurate estimate. Yields True in far fewer cases than before,
27583 improving the quality of code that depends on this test.
27585 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27586 over both visible and private declarations to remove them from tree,
27587 and mark subprograms declared in package as eliminated, to prevent
27588 spurious use in subsequent compilation of generic units in the context.
27590 * exp_util.ads: Minor cleanup in variable names
27592 * sem_eval.ads, sem_eval.adb: Minor reformatting
27593 (Compile_Time_Known_Bounds): New function
27595 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27597 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27598 determining whether an unchecked conversion is needed for the argument
27599 of an initialization call.
27601 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27603 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27604 that appears in the instantiation rather than the internal subtype
27605 generated in the wrapper package, to avoid anomalies in gigi when the
27606 target is derived from a private type whose full view is an access type.
27608 2005-03-15 Robert Dewar <dewar@adacore.com>
27610 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27612 Add documentation to replace the use of this flag
27613 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27616 2005-03-15 Thomas Quinot <quinot@adacore.com>
27618 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27619 here from exp_attr so it can be shared between exp_attr and exp_dist.
27620 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27621 all TSS names, not a subset thereof, and the previous name introduced
27622 an unnecessarily confusion that a distinction might exist between
27623 "OK" TSS names and some "not OK" TSS names.
27625 2005-03-15 Doug Rupp <rupp@adacore.com>
27627 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27630 2005-03-15 Pascal Obry <obry@adacore.com>
27631 Eric Botcazou <ebotcazou@adacore.com>
27635 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27636 when IN_RTS. This is to work around a bootstrap path problem.
27638 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27639 table and pass it to __gnat_install_SEH_handler().
27640 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27642 * lang.opt: Fix specification of -fRTS=.
27644 2005-03-15 Doug Rupp <rupp@adacore.com>
27645 Bernard Banner <banner@adacore.com>
27646 Vincent Celier <celier@adacore.com>
27647 Arnaud Charlet <charlet@adacore.com>
27650 This change works fine when gnatlib is built from the gcc directory,
27651 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27652 is not passed to ada/Makefile.in, so more work is needed by a
27653 Makefile/configure expert.
27655 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27656 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27657 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27659 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27660 Run ranlib on libgccprefix.a
27661 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27662 (ADA_INCLUDE_SRCS): Split Ada packages.
27664 2005-03-15 Robert Dewar <dewar@adacore.com>
27666 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27668 * impunit.adb: Add GNAT.UTF_32
27670 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27672 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27673 now uses GNAT.UTF_32).
27675 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27676 capabilities for categorizing characters using Unicode categories
27678 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27680 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27681 instantiation that has been rewritten as a package body, retrieve spec
27682 to generate proper name for implicit_with_clause.
27683 (Install_Parents): Recognize a parent that is an instantiation but has
27684 been rewritten as a package declaration during analysis.
27686 2005-03-15 Javier Miranda <miranda@adacore.com>
27687 Ed Schonberg <schonberg@adacore.com>
27689 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27690 parameter reported some error we immediately return. This improves the
27691 behaviour of the frontend in case of errors.
27692 (Install_Parent, Remove_Parent): Introduce new flag
27693 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27694 ancestor of a generic child unit, when the child is being instantiated.
27695 (Inline_Instance_Body): If we are compiling the private
27696 part or the body of a child unit, restore the proper visibility of the
27697 parents after compiling the instance body.
27699 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27700 Javier Miranda <miranda@adacore.com>
27703 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27704 of a private type, in which case it is underlying_type that denotes
27705 the proper task. Also modified to use the new entity attribute
27706 that is directly available in the task type and task subtype entities
27707 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27708 arrays when other dimensions than the first are constrained by
27709 discriminants of an enclosing record.
27710 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27711 a combination of indexed and selected components, find ultimate entity
27712 and generate the appropriate reference for it, to suppress spurious
27714 (Note_Possible_Modification): If an entity name has no entity, return.
27715 (Is_Variable): A function call never denotes a variable.
27716 (Requires_Transient_Scope): For record types, recurse only on
27717 components, not on internal subtypes that may have been generated for
27718 constrained components.
27720 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27722 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27723 Eliminated as candidates for resolution. Both efficient, and avoids
27724 anomalies with operators declared in deleted code.
27725 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27726 expansion is disabled (as when compiling a generic) to prevent spurious
27727 warnings on prefixes of selected components.
27729 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27731 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27732 attached to a list before checking whether it appears in the private
27733 declarations of the current package.
27734 (Make_Inequality_Operator): Insert declaration in proper declarative
27735 list rather than just setting the Parent field, so that
27736 Is_Private_Declaration can handle it properly.
27738 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27740 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27741 a renaming a body, check that the renamed subprogram in not intrinsic.
27742 (Find_Direct_Name): If several use_visible entities hide
27743 each other, and the context is a predefined file compiled through
27744 rtsfind, keep only the entity that comes from a predefined file.
27746 2005-03-15 Geert Bosch <bosch@adacore.com>
27748 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27749 long float padding to also cover AMD64 and IA64.
27751 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27753 * s-imgwch.adb: Add with and use of Interfaces.
27754 (Img_Wide_Character): Change type of Val to Unsigned_16.
27755 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27757 2005-03-15 Matthew Gingell <gingell@adacore.com>
27759 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
27761 2005-03-15 Robert Dewar <dewar@adacore.com>
27763 * usage.adb: Add missing lines for -gnat95 and -gnat05 switches
27765 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
27767 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
27769 2005-03-15 Robert Dewar <dewar@adacore.com>
27771 * s-bitops.adb, s-bitops.ads,

27782 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27784 * utils2.c (build_binary_op): Fix typo.
27786 2005-03-15 Doug Rupp <rupp@adacore.com>
27788 * s-crtl.ads (popen,pclose): New imports.
27790 2005-03-15 Cyrille Comar <comar@adacore.com>
27792 * comperr.adb (Compiler_Abort): remove references to obsolete
27793 procedures in the bug boxes for various GNAT builds.

28208 describing the new layout.
28209 (Dispatch_Table): The expander computes the actual array size, allocates

28230 and result, and issuing an error if there is no controlling type for
28231 the formal subprogram.
28232 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28233 which is an unclean use of that field, we set the new field

28247 subprogram only if inner one comes from source.
28248 (Analyze_Function_Call): If the call is given in object notation, the

28250 argument list. After analyzing the name, if the call has been rewritten
28251 and the result type is set, no further analysis is needed.
28252 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28253 mark in function specification, in a context where the formals are
28254 visible and hide outer homographs.
28256 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28257 as the tagged type for the cases of abstract formal subprograms and
28258 renamings of those. Clean up spec comments.
28259 (Check_Dispatching_Context): Add error message to indicate "abstract
28260 procedure", covering the case of a call to a formal abstract procedure
28261 that has statically tagged operands.
28262 (Check_Dispatching_Call): Check for the case of an actual given by
28263 a tag-indeterminate function call whose type is an ancestor of the
28264 containing call's associated tagged type. This situation can occur
28265 for inherited primitives with function defaults. In this case we
28266 use the tagged type's tag directly as the controlling argument for

28343 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28347 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28348 on the field if Pragma Component_Alignment (Storage_Unit).
28349 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28350 side-effects as if it were a constant; also make SAVE_EXPR to protect

28370 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28371 component of an array of arrays in an assignment context, and the
28372 aggregate has component associations that require sliding on
28373 assignment, force reanalysis of the aggregate to generate a temporary
28374 before the assignment.

28393 Arnaud Charlet <charlet@adacore.com>
28395 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28396 address of the exception registration. The Win32 version of this
28397 routine calls __gnat_install_SEH_handler() to initialize the SEH
28398 (Structured Exception Handling) handler.
28399 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28400 SEH (Structured Exception Handling) now.
28401 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28402 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28403 preprocessor condition protecting the call to the extra eh setup
28404 subprogram, which is only available for the ppc target.
28405 (__gnat_clear_exception_count): replaced reference to
28406 variable taskIdCurrent by call to taskIdSelf(), cleaner.

28415 for the SEH (Structured Exception Handling) support.
28417 * raise.h: (__gnat_install_SEH_handler): New prototype.
28418 Update copyright notice.
28420 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28450 2005-02-09 Vincent Celier <celier@adacore.com>
28452 * prj-makr.adb (Process_Directory): Put file name in canonical case
28453 before matching against the patterns.
28454 If gnatname has been invoked as <prefix>-gnatname
28455 then invoke the compiler as <prefix>-gcc, not just "gcc".
28457 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28459 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28460 with expansion disabled. The actual subtype is needed among other
28461 places when the selected component appears in the context of a loop
28462 bound, and denotes a packed array.
28463 (Operator_Check): Always use the first subtype in the
28464 error message, to avoid the appearance of internal base types.
28465 (Transform_Object_Operation): Copy each actual in full
28466 to the parameter associations of the constructed call, rather than
28467 using the shallow copy mechanism of New_Copy_List. This ensures that
28468 the chaining of named associations is done properly.
28469 (Complete_Object_Operation): Rewrite node, rather than
28470 replacing it, so that we can trace back to the original selected
28473 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28474 and calls that use object notation, if the called function is not
28475 declared in a withed unit, place the elaboration constraint on the
28476 unit in the context that makes the function accessible.
28477 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28478 imposes an elaboration constraint between two packages.
28480 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28482 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28483 views of a private type after handling its private dependents, to
28484 maintain proper stack discipline between entry and exit from the

28510 we now use by default.
28512 * xsnames.adb: Adjust end of file test to look for five space followed
28513 by '#' instead of six spaces. The format of xsnames.adb was modified
28514 in the last update.
28516 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28519 * clean.adb: Minor reformatting.

28527 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28530 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28532 2005-02-09 Sergey Rybin <rybin@adacore.com>
28534 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28535 the difference between compact and incompact layout and add the record
28536 representation clause to the example illustrating different layouts.
28537 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28538 component clauses").
28540 2005-02-09 Florian Villoing <villoing@adacore.com>
28542 * gnat_ugn.texi: Fix typos.
28543 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28592 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28594 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,

29263 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29264 with an implicit dereference as its prefix, use
29265 Insert_Explicit_Dereference instead of merely rewriting the prefix into
29266 an explicit dereference. This ensures that a reference to the original
29267 prefix is generated, if appropriate.
29269 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29270 dereference is rewritten to an explicit one, generate a reference to
29271 the entity denoted by its prefix using the original prefix node, so
29272 the dereference can be properly recorded as a read of the denoted
29273 access value, if appropriate.
29275 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29276 emitting 'assigned but never read' warning on a variable on the basis
29277 that it has an access type.
29278 (Check_References): Emit unreferenced warning when the scope is a

29287 * exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
29288 leaving call unchanged.
29289 This deals with the case where the pragma Import specified
29290 an external name, to be handled by the back end.
29292 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29293 subprogram which is Imported with convention Intrinsic if an
29294 External_Name argument is specified.
29295 (Process_Import_Or_Interface): Properly diagnose link name argument.
29296 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
29297 with Sem_Ch6.Cannot_Inline.
29298 (Process_Inline): Provide separate warning for inapplicable inline
29300 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
29301 treatment is uniform on different targets.

29316 for generation of DSA code targeted to the PolyORB PCS.
29317 (Add_Stub_Type): Rewrite to isolate the parts that are specific to one
29318 implementation of the partition communication subsystem in ancillary
29320 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
29321 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29322 PCS-specific part of Add_Stub_Type.
29323 (Insert_Partition_Check): Use runtime library function to perform
29326 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
29327 (RE_Same_Partition): New entity, from s-parint.

29346 2004-12-07 Ed Schonberg <schonberg@adacore.com>
29349 (Generate_Reference): Handle properly a reference to an entry formal,
29350 when an accept statement has a pragma Unreferenced for it.
29352 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29353 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29354 the body, to ensure that warnings are properly emitted for each accept
29355 statement of a given task entry.
29357 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
29359 * Makefile.in: Add support for foreign threads on VMS.

29377 (Remove_Next_Debug): Same fix
29379 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29380 maintain back pointers now, though we did not used to, and comments
29382 (Prepend): Remove pragma Inline.
29383 (Remove_Next): Same cleanup
29385 2004-12-07 Thomas Quinot <quinot@adacore.com>
29387 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29388 used to record an implicit dereference as a read operation on its
29389 prefix when operating under -gnatc. Necessary to avoid spurious
29390 'variable assigned but never read' warnings in that mode.
29391 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29392 is a non-overloaded implicit dereference, call the above subprogram to
29393 ensure proper recording of references.
29395 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29397 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29398 to be resolved later as part of Analyze_Iteration_Scheme's call to
29401 2004-12-07 Ed Schonberg <schonberg@adacore.com>
29403 * sem_ch8.adb (Find_Type): If node is a reference to 'Base and the

29445 2004-12-07 Vincent Celier <celier@adacore.com>
29447 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29448 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29449 and -eit to -ept. Added qualifier
29450 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29452 2004-11-27 Andreas Schwab <schwab@suse.de>
29454 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29456 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29458 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29459 internal implementation unit GNAT.Sockets.Thin,
29460 as their usage for sockets is non-portable (using the read and write
29461 functions from the system runtime library is fine on UNIX but won't
29462 work under Windows).
29464 * mingw32.h: Update copyright notice.
29466 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29468 * ada-tree.h: Minor reformatting of previous change to avoid lines

29509 2004-11-18 Olivier Hainque <hainque@adacore.com>
29511 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29512 address of which may be used to represent "others" and "all others"
29513 choices in exception tables, instead of the current harcoded
29514 (void *)0 and (void *)1.
29515 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29517 * gigi.h (others_decl, all_others_decl): New decls representing the
29518 new Others_Value and All_Others_Value objects.
29519 (struct attrib): Rename "arg" component as "args", since GCC expects a
29520 list of arguments in there.
29522 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29523 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29526 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29527 others_decl and all_others_decl instead of hardcoded dummy addresses
29528 to represent "others" and "all others" choices, which is cleaner and
29529 more flexible with respect to the possible eh pointer encoding policies.
29531 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29532 (process_attributes): Account for the naming change of the "args"
29533 attribute list entry component.
29535 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29536 cumulating attributes for different entities into a single list.
29537 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29538 attributes for the current entity and propagate first subtype
29539 attributes to other subtypes.
29540 <E_Procedure>: Attribute arguments are attr->args and not
29541 attr->arg any more.
29542 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29543 argument provided, as this is what GCC expects. Use NULL_TREE instead
29546 2004-11-18 Robert Dewar <dewar@adacore.com>
29548 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29580 (Insert_Partition_Check): Remove fossile code.
29581 (First_RCI_Subprogram_Id): Document this constant.
29582 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29584 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29585 replaced with calls to Get_Library_Unit_Name_String. Previously there
29586 were several instances of the same code in different locations in the
29587 compiler; this checkin completes the replacement of all of these
29588 instances with calls to a common subprogram.
29589 Minor reformatting.
29591 * sem_dist.adb: Remove comment noting that RPC receiver generation
29592 should be disabled for RACWs that implement RASs.

29617 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29618 (Expand_Pragma_Psect_Object): New procedure
29619 These procedures contain the revised and cleaned up processing for
29620 these two pragmas. This processing was formerly in Sem_Prag, but
29621 is more appropriately moved here. The cleanup involves making sure
29622 that the pragmas are properly attached to the tree, and that no
29623 nodes are improperly shared.
29625 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29626 pragmas to Exp_Prag, which is more appropriate.
29627 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to

29629 Use new Make_String_Literal function with string.
29631 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29632 that are functions return universal values, that have to be converted
29633 to the context type.
29634 Use new Make_String_Literal function with string.
29635 (Get_Stream_Convert_Pragma): New function, replaces the use of
29636 Get_Rep_Pragma, which had to be kludged to work in this case.
29638 * freeze.adb: Use new Has_Rep_Pragma function
29640 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29641 function with string.
29642 Use new Has_Rep_Pragma function.

29668 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29669 discriminant of a constrained subtype, analyze the copy of the
29670 corresponding constraint, because in some cases it may be only
29671 partially analyzed.
29672 Removes long-lived ??? comments.
29674 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29675 handled controlled or secondary-stack expressions within the
29676 iteration_scheme of a loop.
29678 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29679 bounds that may contain functions calls, to prevent memory leaks when
29680 the bound contains a call to a function that uses the secondary stack.
29681 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29682 generate temporaries for loop bounds that might contain function calls
29683 that require secondary stack and/or finalization actions.
29685 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29686 selected component and the selector is overloadable (not just a
29687 function) treat as function call, Analyze_Call will disambiguate if
29689 (Analyze_Selected_Component): Do not generate an actual subtype for the
29690 selected component if expansion is disabled. The actual subtype is only
29691 needed for constraint checks.
29692 (Analyze_Allocator): If restriction No_Streams is set, then do
29693 not permit objects to be declared of a stream type, or of a
29694 composite type containing a stream.
29696 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29697 No_Streams no longer prohibits with'ing this package.
29699 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29700 discriminants, but the parent base has unknown discriminants, there is
29701 no discriminant constraint to inherit. Such a discrepancy can arise
29702 when the actual for a formal type with unknown discriminants is a
29703 similar private type whose full view has discriminants.
29704 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29705 do not permit objects to be declared of a stream type, or of a
29706 composite type containing a stream.
29708 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29710 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29711 protected operations.
29713 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29714 generated name, it complicates decoding in gdb and hinders debugging
29715 of protected operations.

29717 flag for the protected entry barrier function.
29718 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info

29733 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29734 type of the object with the packed array type, set the Analyzed flag
29735 on the object if it is an entity or simple indexed component, to avoid
29736 spurious type errors.

29758 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29759 for Detect_Blocking which is redundant with the check done within the
29760 procedure Protected_Single_Entry_Call.
29761 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29762 Detect_Blocking which is redundant with the check done within the
29763 procedure Protected_Single_Entry_Call.

29767 * makegpr.adb (Compile): Put the compiling switches (in package
29768 Compiler and on the command line) immediately after "-c", instead of
29769 at the end of the command line invocation of the compiler, when
29770 compiling a non-Ada file.
29771 (Build_Global_Archive): When there is no need to rebuild the archive,
29772 set Global_Archive_Exists, so that the archive is passed to the linker
29775 2004-11-18 Robert Dewar <dewar@adacore.com>
29776 Sergey Rybin <rybin@adacore.com>
29779 Remove extra paren check from list of checks for redundant constructs
29780 Add documentation of new -gnatyx style check (check extra parens)
29781 Remove paragraph about gnatelim debug options.
29783 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29784 objects rather than forbidding dependencies on the package Ada.Streams.
29786 * sinfo.ads: Add ??? note that we should document pragmas passed to
29789 * g-expect.ads: Fix a few typos in the comments.
29791 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29793 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29796 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29798 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29800 2004-11-07 Andreas Schwab <schwab@suse.de>
29802 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29804 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29807 * Makefile.in (darwin): Set soext to .dylib.
29809 2004-10-26 Vincent Celier <celier@gnat.com>
29810 Thomas Quinot <quinot@act-europe.fr>
29812 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29813 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29814 there is no use of GNAT.Sockets.Constants.
29815 Remove remaining pragma Import for C_Write
29816 Remove C_Read and C_Write from internal implementation unit
29817 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29818 the read and write functions from the system runtime library is fine
29819 on UNIX but won't work under Windows).
29821 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29822 (Check_Selector): Use C_Recv instead of C_Read.
29823 Selectors are the GNAT.Sockets abstraction to perform a select()
29824 call on a set of descriptors. To allow abortion of an ongoing
29825 select operation, some data is written to a dedicated socket that
29826 is always monitored.
29827 Under Windows, the write and read library functions cannot operate
29828 on sockets, so we need to use send and recv instead, which is portable
29829 across all supported platforms.
29831 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29832 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29833 (using the read and write functions from the system runtime library is
29834 fine on UNIX but won't work under Windows).
29836 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29838 * mlib-tgt-darwin.adb: New file.
29840 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29841 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29842 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29843 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29846 * Makefile.in: Add support for building shared libraries under Darwin.
29847 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29848 the low level EH init subprogram to be called from __gnat_initialize.
29850 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29851 indicates which options to pass to the archive indexer.
29853 * mlib-utl.adb: Add support for calling ranlib with additional
29854 options. This is needed for instance under Mac OS X.
29855 (Ranlib_Options): New global variable, used to store the potential
29856 options to pass to ranlib.
29857 (Ar): Use Ranlib_Options when spawning ranlib.
29858 (Initialize): Set the value of ranlib option.
29860 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29862 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29863 instead of 8K, to reflect the real potential needs for stack-checking
29866 2004-10-26 Pascal Obry <obry@gnat.com>
29868 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29870 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29871 Windows only the initial thread stack size can be set so it is good to
29872 start we a low stack size.
29873 The OS will adjust the size as needed.
29875 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29876 Nicolas Setton <setton@act-europe.fr>
29878 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29879 "__unix__" instead of "unix".
29880 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29881 sections were just mistakenly ignored. The former is
29882 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29883 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29884 of hpux. This prevents an unwanted definition of the symbol
29885 convert_addresses in adaint.o.
29887 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29889 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29890 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29892 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29894 * a-filico.ads, a-filico.adb: fix incorrect header.
29896 2004-10-26 Javier Miranda <miranda@gnat.com>
29898 * a-ststio.ads: Fix typo in identifier
29900 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29902 * sem_ch4.adb: Minor reformatting.
29904 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29906 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29907 enabled, check the result of unary and binary operations when the
29908 expression is the right-hand side of an assignment.
29910 2004-10-26 Vincent Celier <celier@gnat.com>
29912 * clean.adb (Delete): Do not output warnings when in quiet output and
29913 not in verbose mode.
29914 (Force_Deletions): New Boolean flag, defaulted to False
29915 (Delete): Only delete a file if it is writable, and when
29916 Force_Deletions is True.
29917 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29918 (Usage): Line for new switch -f
29919 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29922 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29924 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29925 JM type only if its size matches that of the wrapper. When a size is
29926 prescribed and the field is not aliased, remove the wrapper of a JM
29927 type only if the size is not greater than that of the packed array.
29928 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29931 2004-10-26 Geert Bosch <bosch@gnat.com>
29933 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29934 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29935 (Pred): Implement in terms of Succ.
29937 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29939 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29940 unchecked conversion is safe for in-place use if the expression of the
29941 conversion is safe.
29942 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29943 be expandable in place even if the aggregate does not come from source.
29944 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29945 designated object of an allocator in place, rather than building it
29946 first on the stack. The previous scheme forces a full copy of the array,
29947 and may be altogether unsusable if the size of the array is too large
29948 for stack allocation.
29950 2004-10-26 Robert Dewar <dewar@gnat.com>
29952 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29953 compares if the component is atomic.
29955 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29956 array assignment if the component type is atomic.
29958 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29959 Eric Botcazou <ebotcazou@act-europe.fr>
29961 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29962 is aliased and is a by_reference type, do not pass by copy.
29963 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29964 detect whether the call is in the right side of an assignment or
29965 the expression of an object declaration. Recurse on component
29966 association within aggregates.
29967 Call it in the condition that determines whether the temporary is
29968 necessary for correct stack-checking.
29970 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29972 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29973 RACW_Type, used in the PolyORB version.
29974 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29975 version and the GARLIC version.
29977 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29978 Rename RCI_Info to RCI_Locator for better consistency between the
29979 GARLIC and PolyORB versions of the distributed systems annex.
29980 (DSA_Implementation_Name): This enumeration lists the possible
29981 implementations of the Partition Communication Subsystem for the
29982 Distributed Systems Annex (DSA). The three available implementations
29983 are the dummy stub implementation (No_DSA), and two versions based on
29984 two different distribution runtime libraries: GARLIC and PolyORB. Both
29985 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29987 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29990 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29991 between the GARLIC and PolyORB versions of the distributed systems
29993 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29995 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29997 * gnat1drv.adb: Suppress calling the back end when
29998 Frontend_Layout_On_Target is true.
30000 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30002 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30003 Set_Read_Only): New subprograms.
30004 These new routines allow the user to set or unset the Owner execute
30005 and Owner write permission flags on a file.
30007 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30008 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30010 2004-10-26 Matthew Gingell <gingell@gnat.com>
30012 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30014 2004-10-26 Pascal Obry <obry@gnat.com>
30016 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30017 memory before the faulting page we properly test the process read
30018 access for this address using appropriate Win32 routine.
30019 (HPUX sections): guard with "__hpux__" instead of "hpux".
30021 2004-10-26 Robert Dewar <dewar@gnat.com>
30023 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30024 entry parameter if pragma Unreferenced set, since we do not properly
30025 handle the case of multiple parameters.
30027 2004-10-26 Vincent Celier <celier@gnat.com>
30029 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30030 (Ada_Objects_Path.Add): For a library project, add to the object path
30031 the library directory only if there is no object directory or if the
30032 library directory contains ALI files.
30033 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30035 2004-10-26 Vincent Celier <celier@gnat.com>
30037 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30038 extension of library projects.
30040 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30041 path defaults to ".:<prefix>/lib/gnat".
30042 (Parse): For an extending all project, allow direct import of a project
30043 that is virtually extended.
30045 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30046 the specified name is directly imported, return its ID. Otherwise, if
30047 an extension of this project is imported, return the ID of the
30050 2004-10-26 Robert Dewar <dewar@gnat.com>
30052 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30053 (Sub3): New procedure, used by Scaled_Divide
30054 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30055 correct more than one instance of failure to propagate carries
30057 (Double_Divide): Handle overflow case of largest negative number
30058 divided by minus one.
30060 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30061 the case of a quotient value out of range.
30064 2004-10-26 Robert Dewar <dewar@gnat.com>
30066 * s-bitops.adb (Bit_Eq): Remove redundant check.
30068 * s-bitops.ads: Minor comment updates
30069 Change some occurrences of Address to System.Address
30071 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30073 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30075 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30076 accessibility check to prefix that is a protected operation.
30078 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30080 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30081 empty, post message on stub.
30083 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30084 Javier Miranda <miranda@gnat.com>
30086 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30087 current instance appears within a unit that is directly in the context
30089 Used to determine whether the body of the instance should be analyzed
30090 immediately after its spec, to make its subprogram bodies available
30091 for front-end inlining.
30092 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30093 constraint is not allowed on the component type (AARM 12.5.3(3))
30095 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30097 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30098 'Storage_Pool): enhance, document & limit detection of non-sharable
30101 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30103 * s-pooglo.ads: Add more documentation now that this pool is properly
30106 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30108 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30109 or protected type with discriminants, do not constrain the
30110 corresponding record type if the subtype declaration has no
30111 discriminant constraints. This can be the case in source code, or in
30112 the subtype declaration created to rename an actual type within an
30115 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30117 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30118 different kind of stub (possibly wrong name for file), do not check
30120 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30121 includes call to some function that returns an unconstrained type, do
30124 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30126 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30127 appear in the code for the main unit. Dependencies among units in the
30128 context of the main unit are established when those other units are
30129 compiled. Otherwise spurious elaboration constraints can generate
30130 incorrect elaboration circularities.
30132 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30133 Ed Schonberg <schonberg@gnat.com>
30135 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30136 subprogram is called with a parameter that is not an object name. This
30137 situation arises for some cases of illegal code, which is diagnosed
30138 later, and in this case it is wrong to call Is_Aliased, as that might
30139 cause a compiler crash.
30140 (Explain_Limited_Type): Refine previous fix to include
30141 inherited components of derived types, to provide complete information.
30143 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30144 is the prival for a protected object.
30145 It is necessary to mark this entity as a variable, in addition to
30146 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30147 modified to avoid checking the Aliased flag on entities that are not
30148 objects. (Checking that flag for non-objects is erroneous and could
30149 lead to a compiler crash).
30151 2004-10-26 Robert Dewar <dewar@gnat.com>
30153 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30154 X_Frac = 0.5, then we know that the number X must be positive.
30155 (Succ): Remove the same redundant test, and also fix the primary test
30156 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30158 (Decompose): Add fuller comments to spec
30160 2004-10-26 Pascal Obry <obry@gnat.com>
30162 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30163 validity (process must have read access). Set to 0 in all other cases.
30164 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30165 violation on Win32.
30166 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30167 segmentation violation.
30169 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30171 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30172 whose type is a constructed subtype of an aliased object with an
30173 unconstrained nominal subtype, convert the actual to the constructed
30174 subtype before taking its address.
30176 2004-10-26 Vincent Celier <celier@gnat.com>
30178 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30179 (Is_Path_Name_Case_Sensitive): New function
30181 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30182 (Base_Name, Simple_Name, Current_Directory, Compose,
30183 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30186 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30187 Vasiliy Fofanov <fofanov@act-europe.fr>
30188 Vincent Celier <celier@gnat.com>
30190 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30191 "memory management issues" section and document some of the useful
30192 memory pools provided as part of the GNAT library.
30193 Remove "virtual" from declaration of A::method2 in
30194 the simple example of Ada/C++ mixed system.
30195 Library Projects may be virtually extended: their virtual extensions
30196 are not Library Projects.
30197 Added section on extending project hierarchies.
30199 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30201 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30203 (__gnat_portable_spawn): Remove const.
30205 * mingw32.h (MAXPATHLEN): Check for previous definition.
30207 2004-10-17 Matthias Klose <doko@debian.org>
30209 * gnatvsn.ads: Set gnat library version to 4.0.
30211 2004-10-05 Vincent Celier <celier@gnat.com>
30213 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30215 2004-10-04 Laurent Guerby <laurent@guerby.net>
30218 * Makefile.in: Define and use RANLIB_FLAGS.
30220 2004-10-04 Pascal Obry <obry@gnat.com>
30222 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30223 other x86 platforms).
30225 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30227 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30228 in general and triggers stack alignment adjustment for thread entry
30229 points on targets where this is necessary.
30231 2004-10-04 Bernard Banner <banner@gnat.com>
30234 * Makefile.in: Add section for powerpc linux
30235 Add variant i-vxwork-x86.ads
30237 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30239 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30241 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30242 table registration calls when need be. Ensures no reference to the crt
30243 ctors symbol are issued in the SJLJ case, which avoids possible
30244 undefined symbol errors in the case of modules to be statically linked
30247 2004-10-04 Javier Miranda <miranda@gnat.com>
30249 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30250 in-line the code corresponding to subprogram Analyze_Actuals. In
30251 addition, analyze the actuals only in case of subprogram call.
30253 2004-10-04 Ed Falis <falis@gnat.com>
30255 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30257 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30259 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30260 in the documentation.
30262 2004-10-04 Robert Dewar <dewar@gnat.com>
30264 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30266 (Analyze_Block_Statement): Add circuitry to detect following dead code
30267 (Check_Unreachable_Code): Handle case of block exit
30269 2004-10-04 Robert Dewar <dewar@gnat.com>
30271 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30272 (XMatchD): Avoid warning for Logic_Error call
30274 2004-10-04 Robert Dewar <dewar@gnat.com>
30276 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30277 consider expressions buried within a procedure actual to be an actual.
30278 This caused some blowups with uses of packed slices within a procedure
30281 2004-10-04 Robert Dewar <dewar@gnat.com>
30283 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30284 longer need to be initialized to zero.
30285 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30286 initialized to zero.
30288 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30289 considered valid, even if the representation is modular. That's correct
30290 now that we no longer initialize packed modular arrays to zero.
30292 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30293 suffixes. These are now documented as the only cases in which the
30294 debugger ignores outer records.
30295 Previously, the spec allowed arbitrary suffixes for this purpose.
30296 Change name of LJM to JM for packed array pad records
30297 Create separate section on packed array handling, and add a whole new
30298 set of comments to this section describing the situation with packed
30299 modular types and justification requirements depending on endianness.
30301 2004-10-04 Robert Dewar <dewar@gnat.com>
30303 * a-except.adb: Add a comment for last change
30305 * einfo.ads: Minor spelling correction in comment
30307 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30309 * sem_ch11.adb: Fix a case of using | instead of \ for continuation

30316 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30317 Inline_Always when in Configurable_Run_Time mode.
30319 * sem_prag.adb (Process_Convention): If entity is an inherited
30320 subprogram, apply convention to parent subprogram if in same scope.
30321 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30322 when in Configurable_Run_Time mode.
30324 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30326 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30327 class_wide type after component list has been inherited.

30331 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30332 Denotes_Previous_Actual, to handle properly the case of a private
30333 actual that is also the component type of a subsequent array actual.
30334 The visibility status of the first actual is not affected when the
30335 second is installed.
30336 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30337 make fully recursive the treatment of formals of packages declared
30339 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30340 the above on exit from an instantiation.
30341 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30342 current instantiation which is now complete.
30343 (Analyze_Package_Instantiation): No instantiated body is needed if the
30344 main unit is generic. Efficient, and avoid anomalies when a instance
30345 appears in a package accessed through rtsfind.
30347 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30349 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30350 do not generate a declaration for a temporary if the call is part of a
30351 library-level instantiation.
30353 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30355 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30356 searching for a limited component to flag.
30358 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30359 expansion of Input, to account for the fact that the implicit call
30360 generated by the attribute reference must freeze the user-defined
30361 stream subprogram. This is only relevant to 'Input, because it can
30362 appear in an object declaration, prior to the body of the subprogram.
30364 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30365 expansion can proceed and further errors uncovered.
30366 (Minor clean up): Fix cases of using | instead of \ for continuation
30369 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30371 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30373 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30374 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30375 Use gcc_assert and gcc_unreachable.
30377 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30378 specified alignment before validating size.
30379 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30380 stripped-down declaration for the type of the inner field when making
30383 * utils.c (finish_record_type): Do not compute the size in units
30384 incrementally. Instead compute it once for the rep clause case.
30385 Use gcc_assert and gcc_unreachable.
30387 2004-10-04 Vincent Celier <celier@gnat.com>
30389 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30391 (Is_Valid_Path_Name): Take '/' as a directory separator.
30393 2004-10-04 Vincent Celier <celier@gnat.com>
30395 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30396 (Extended_Project) only if Extended_Project is defined, to avoid
30398 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30400 (Parse_Single_Project): Ditto.
30402 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30403 Add_To_Project_Path for virtual projects.
30405 2004-10-04 Vincent Celier <celier@gnat.com>
30407 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30411 parameter Options_2.
30413 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30414 Build_Dynamic_Library with an empty Options_2.
30416 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30419 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30420 directory separator, if any.
30421 (Gprmake): Do not allow mains on the command line for library projects.
30422 Do not attempt to link when the project is a library project.
30423 (Library_Opts): New table to store Library_Options.
30424 (Build_Library): If Library_Options is specified, pass these options
30425 when building a shared library.
30427 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30429 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30430 the end of this procedure now that the unlock operation was inserted
30433 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>

30448 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30449 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30450 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30451 used to signal whether the compiler creates the required stacks and
30452 descriptors for the different tasks (when True) or it is done by the
30453 underlying operating system at run time (when False).
30454 It is initially set to False in all targets.
30456 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30457 if it is supported by the target.
30458 (Make_Task_Create_Call): Pass the stack address if it has been
30459 previously created. Otherwise pass a Null_Address.
30461 * snames.adb: Add _stack.
30463 * snames.ads: Add Name_uStack. Required to allow the expander to
30464 statically allocated task stacks.
30466 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30467 Stack_Address argument.
30468 Check that its value is equal to Null_Address because this target does
30469 not support the static stack allocation.
30471 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30473 * usage.adb: Change "pragma inline" to "pragma Inline" in information

30478 * exp_dist.adb: Split declaration of asynchronous flag out of
30479 Add_RACW_Read_Attribute.
30480 Minor reformatting for better alignment with PolyORB version.
30481 Store the entity for the asynchronous flag of an RACW, rather than the
30482 expression, in the asynchronous flags table. This will allow this flag
30483 to be used in other subprograms beside Add_RACW_Read_Attribute.
30485 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30487 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30491 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30492 sockets constant MSG_NOSIGNAL (Linux-specific).
30493 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30494 all Send operations.
30495 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30496 from trigerring SIGPIPE.
30497 Rename components to avoid clash with Ada 2005 possible reserved
30499 (Check_Selector): When the select system call returns with an error
30500 condition, propagate Socket_Error to the caller.
30502 2004-10-01 Jan Hubicka <jh@suse.cz>
30504 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30506 2004-09-23 Robert Dewar <dewar@gnat.com>

30510 instead do this at freeze time (we won't do it if there is an address
30512 Change "pragma inline" to "pragma Inline" in information and error
30514 Minor reformatting.
30516 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30517 right way of doing things after all.
30518 (Freeze_Entity): For object, set Is_Public for imported entities
30519 unless there is an address clause present.
30521 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30523 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30524 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30525 ensures proper handling of types with rep clauses, which might have
30526 their TYPE_SIZE set already.
30528 2004-09-21 Robert Dewar <dewar@gnat.com>
30530 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30531 packed array types in both little- and big-endian cases. This change
30532 ensures that we no longer count on the unused bits being initialized
30533 for such types (and in particular ensures that equality testing will
30534 only read the relevant bits).
30535 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30536 These changes mean that we no longer need to initialize small packed
30538 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30539 optimization to an LJM field as to its parent field.
30541 * ada-tree.h, trans.c, utils.c, utils2.c:
30542 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30544 2004-09-20 Jan Hubicka <jh@suse.cz>
30546 * utils.c (gnat_finalize): Remove.
30547 (end_subprog_body): Directly call cgraph_finalize_function;
30548 do not lower the nested functions.
30550 2004-09-20 Robert Dewar <dewar@gnat.com>
30553 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30554 if an address clause is present, since that means that the Import
30557 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30559 * 5tsystem.ads: Removed, no longer used.
30561 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30562 Zack Weinberg <zack@codesourcery.com>
30564 * ada-tree.def: Use tree_code_class enumeration constants
30565 instead of code letters.

30583 an existing directory.
30584 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30585 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30586 Convert the result to File_Size.
30588 * prj.ads: (Project_Error): New exception
30590 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30591 Prj.Com, not from Osint.
30592 (Attrs, Package_Attributes): Tables moved to private part of spec
30593 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30595 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30596 Prj.Project_Error after call to Fail.
30597 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30598 Fail. Check that package name is not already in use.
30600 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30601 used by tools, not only by the project manager, and to indicate that
30602 exception Prj.Prj_Error may be raised in case of problem.
30603 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30605 (Attrs, Package_Attributes): Table instantiations moved from the body to
30606 the private part to be accessible from Prj.Attr.PM body.

30609 from new package Prj.Attr.PM.
30610 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30613 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30615 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30616 instead of Elaboration_Checks).
30618 * a-calend.adb: Minor reformatting
30620 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30678 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30679 Common_ATCB record. It contains the dynamic level of protected action
30680 nesting for each task. It is needed for checking whether potentially
30681 blocking operations are called from protected operations.

30719 contains the required machinery for handling that.
30721 * sem_util.ads: Change comment associated to procedure
30722 Check_Potentially_Blocking_Operation.
30723 This procedure does not insert a call for raising the exception because
30724 that is currently done by the run time.
30726 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30728 * init.c: Add the global variable __gl_detect_blocking that indicates
30729 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30730 making the pragma available at run time.
30731 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30733 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if

30738 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30739 DB is found in the ali file. Any unit compiled with pragma
30740 Detect_Blocking active forces its effect in the whole partition.
30742 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30743 Detect_Blocking is active and delay is called from a protected
30746 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30747 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30748 Detect_Blocking is active (0 otherwise).
30749 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30750 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30765 Expand_Record_Extension.
30767 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30768 primitive operations of potentially distributed object types that have
30769 non-controlling anonymous access formals.
30771 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30773 New implementation of expansion for remote access-to-subprogram types,
30774 based on the RACW infrastructure.
30775 This version of sem_dist is compatible with PolyORB/DSA as well as
30778 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30779 Asynchrronous that applies to a remote access-to-subprogram type, mark
30780 the underlying RACW type as asynchronous.
30782 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30783 __gnat_using_gnu_linker to 1.
30785 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30786 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30787 GNAT.Perfect_Hash_Generators, and remove the empty

30792 * exp_ch3.adb (Expand_Derived_Record): Rename to
30793 Expand_Record_Extension.
30794 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30795 a component declaration must remain attached at that point in the
30796 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30797 It is therefore necessary to take a copy of the expression when building
30798 the corresponding assignment statement in the init proc.
30799 As a side effect, in the case of a derived record type, we now see the
30800 original expression, without any rewriting that could have occurred
30801 during expansion of the ancestor type's init proc, and we do not need
30802 to go back to Original_Node.
30804 * exp_ch3.ads (Expand_Derived_Record): Rename to
30805 Expand_Record_Extension.
30807 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30810 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30811 New subprograms. Used to create a proxy tagged object for a remote
30812 subprogram. The proxy object is used as the designated object
30813 for RAS values on the same partition (unless All_Calls_Remote applies).
30814 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30815 System.Partition_Interface.Get_Unique_Remote_Pointer.
30816 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30817 Renamed from Add_RAS_*_Attribute.
30818 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30820 New implementation of expansion for remote access-to-subprogram types,
30821 based on the RACW infrastructure.
30823 * exp_dist.ads (Copy_Specification): Update comment to note that this
30824 function can copy the specification from either a subprogram
30825 specification or an access-to-subprogram type definition.
30827 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30829 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30830 in an instance, between an explicit subprogram an one inherited from a
30831 type derived from an actual.
30833 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30834 add a polling call if the subprogram is to be inlined by the back-end,
30835 to avoid repeated calls with multiple inlinings.
30837 * checks.adb (Apply_Alignment_Check): If the expression in the address
30838 clause is a call whose name is not a static entity (e.g. a dispatching
30839 call), treat as dynamic.
30841 2004-09-09 Robert Dewar <dewar@gnat.com>
30843 * g-trasym.ads: Minor reformatting
30845 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30889 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30890 of variable length temporaries for function return now that the

30942 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
30943 packed indexed component where array is an IN OUT formal. This
30944 generated garbage code previously.

30966 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
30967 pragma Debug as an if statement with a constant condition, for
30968 consistent treatment of entity references contained within the
30969 enclosed procedure call.

30998 2004-09-01 Pascal Obry <obry@gnat.com>
31000 * gprcmd.adb (Extend): Do not output trailing directory separator. This
31001 is not needed and it confuses Windows GNU/make which does not report
31002 directory terminated by a slash as a directory.
31003 (gprcmd): Idem for "pwd" internal command.
31005 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31006 target names rewrite to fix regressions with recent version of
31007 GNU/make. Starting with GNU/make 3.80 the pipe character was not
31008 handled properly anymore.

31060 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31061 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31062 option and not mdll anymore. Update comment.
31064 2004-08-16 Pascal Obry <obry@gnat.com>
31066 * bld.adb (Put_Include_Project): Properly handle directory separators
31069 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31082 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31084 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31085 for a global aliased object with a variable size and an unconstrained
31086 nominal subtype, pretend there is no initializer if the one we have is
31087 incomplete, and avoid referencing an inexistant component in there. The
31088 part we have will be rebuilt anyway and the reference may confuse
31089 further operations.

31111 * rtsfind.adb (Entity_Not_Defined): If the error ocurrs in a predefined
31112 unit, this is an attempt to inline a construct that is not available in
31113 the current restricted mode, so abort rather than trying to continue.
31115 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31116 discriminants that rename those of the parent, recover names of
31117 original discriminants for the constraint on the full view of the
31119 (Complete_Private_Subtype): Do not create a subtype declaration if the
31120 subtype is an itype.
31122 * gnat_rm.texi: Added section on implementation of discriminated
31123 records with default values for discriminants.
31125 2004-08-13 Ed Schonberg <schonberg@gnat.com>

31145 new specification and test explicitly for non-zero return value.
31147 * g-socthi.ads (Is_Socket_In_Set): Declare imported function as
31148 returning C.int, to avoid using a derived boolean type.
31150 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
31151 Duplicate_Subexpr_No_Checks in preference to direct use of
31152 Remove_Side_Effects and New_Copy_Tree.

31176 2004-08-09 Olivier Hainque <hainque@act-europe.fr>
31178 * decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
31179 ignore overflows on low and high bounds of an index to also account for
31180 differences in signedness between sizetype and gnu_index_subtype.
31181 These are as legitimate as the ones caused by a lower TYPE_PRECISION
31184 2004-08-09 Robert Dewar <dewar@gnat.com>
31186 * s-solita.ads, s-solita.adb: Minor reformatting

31192 run time constraint checks.
31194 * vms_conv.ads: Minor reformatting
31196 * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup

31201 * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
31202 pointer (cleanup and necessary for following change).
31203 Define Mark_Id as record containing address of secondary stack, that way
31204 Release does not need to find the stack again, decreasing the number of
31205 calls to Self and improving efficiency.

33103 interpretations for rewritten right operand.
33104 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33779 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to

33808 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33809 overriding, use the operation of the parent unconditionally.
33811 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33812 operation when either operand is a literal, to avoid further
33815 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and

33886 limitation on length of lines when scanning config pragma files.

35095 Analyze_Assignment to proceed.
35097 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35098 complete assignment subtree which is now unnecessary, as the expansion
35099 of inlined call has been improved to preserve a consistent assignment
35100 tree. Note_Possible_Modification must be called only
35101 after checks have been applied, or else unnecessary checks will
35104 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35105 of explicit dereferences that do not Come_From_Source:

35107 pointer (an assignment to an implicit dereference must not be
35108 recorded as modifying the pointer);
35109 - do not rely on Original_Node being present (Analyze_Assignment
35110 calls Note_Possible_Modification on a copied tree).

35113 that is never assigned is encountered, prefer '<pointer> may be null'
35114 warning over '<pointer> is never assigned a value'.

35362 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35363 executable name when not initialized. Otherwise, use its current value.
35365 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35366 initialize it to another executable name than the current one. This
35367 allows to configure paths for an executable name (gnatmake) different
35368 from the current one (gnatdist).
35370 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35372 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35373 current unit cannot be inlined if it appears in the body of a withed
35374 unit, to avoid order of elaboration problems in gigi.
35376 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35377 information for protected (wrapper) operation as well, to simplify gdb
35380 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35381 protected body, indicate that the entity for the generated spec comes
35382 from source, to ensure that references are properly generated for it.
35383 (Build_Body_To_Inline): Do not inline a function that returns a

35391 resolve them with the declared formal types, before rewriting as an
35394 2004-03-29 GNAT Script <nobody@gnat.com>

35417 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35419 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35420 attribute reference does not denote a subtype, it can be any
35421 expression that has a classwide type, potentially after an implicit
35422 dereference. In particular, the prefix can be a view conversion for
35423 a classwide type (for which Is_Object_Reference holds), but it can
35424 also be a value conversion for an access-to-classwide type. In the
35425 latter case, there is an implicit dereference, and the original node
35426 for the prefix does not verify Is_Object_Reference.
35428 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35429 conversion of a discriminant-dependent component of a mutable object
35432 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35434 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35435 inherited, has convention C, and has unconstrained array parameters,
35436 place the corresponding warning on the derived type declaration rather
35437 than the original subprogram.
35439 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35440 indication on renaming declaration, if formal has a box and actual
35443 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35444 determine whether to generate an implicit or explicit reference to
35445 the renamed entity.
35447 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35448 subprogram renaming comes from a defaulted formal subprogram in an
35451 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35453 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35454 value expressions to ensure that calls within a component definition
35455 will be checked (since those are evaluated during the record type's

35507 declaration for a child subprogram body that acts as a spec, indicate
35508 that the entity in the declaration needs debugging information.
35510 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35511 full view if the subtype is created for a constrained record component;
35512 gigi has enough information to construct the record, and there is no
35513 place in the tree for the declaration.
35515 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35516 serial number for the dummy body that is built for analysis, to avoid
35517 inconsistencies in the generation of internal names when compiling

35553 * ada-tree.h: Update copyright notice.
35554 Minor reformatting.
35556 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35558 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35559 as regular exception objects and not as mere integers representing the
35560 condition code. The latter approach required some dynamics to mask off
35561 severity bits, which did not fit well into the GCC table based model.
35562 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35563 exception data objects. We don't it and it would conflict with the other
35564 external symbol we have to generate for such exceptions.
35566 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35567 the special code for VMS exceptions, since these are now represented
35568 as regular exceptions objects.
35570 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35572 * decl.c (debug_no_type_hash): Remove.

35610 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35611 When needed (stack checking) the stack size is retrieved
35612 from the VxWorks kernel.
35614 * Makefile.in: Flag -nostdinc is required when building the run time
35615 for avoiding looking for files in the base compiler.
35616 Add the VxWorks specific version of the package body for
35617 System.Stack_checking.Operations (5zstchop.adb).
35619 * Make-lang.in: Add the object file for
35620 System.Stack_Checking.Operations.

35628 checking from this package to package System.Stack_Checking.Operations.
35629 This way, stack checking operations are only linked in the final
35630 executable when using the -fstack-check flag.

35645 the procedures Add_To_Path_File.
35646 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35647 making sure that each directory is present only once and, for object
35648 dirs, when a directory already present is added, the duplicate is
35649 removed and the directory is always put as the last in the table.
35650 Write the path files at the end of these accumulations.

35862 explicit dereference.
35863 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35864 of non-packed slices, since the dereference action generated by
35865 expansion of the explicit dereference is needed in any case.

35867 analyze and resolve the rewritten explicit dereference so it is seen
35869 (Insert_Dereference_Action): This procedure is now called only for the

36711 No_Requeue_Statements.
36713 * s-rident.ads: Adding restriction No_Requeue_Statements (AI-00249)

36715 kept for backward compatibility.
36717 2004-02-02 Ed Schonberg <schonberg@gnat.com>
36719 * lib.ads, i-cobol.ads, * s-stoele.ads, s-thread.ads, style.ads,

36746 * utils.c (create_field_decl): Augment the head comment about bitfield
36747 creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
36748 here, because the former is not accurate enough at this point.
36749 Let finish_record_type decide instead.
36750 Don't make a bitfield if the field is to be addressable.
36751 Always set a size for the field if the record is packed, to ensure the
36752 checks for bitfield creation are triggered.
36753 (finish_record_type): During last pass over the fields, clear

37259 * rtsfind.adb (Load_Fail): Give full error message in configurable
37260 run-time mode if all_errors mode is set. This was not done in the case
37261 of a file not found, which was an oversight.
37262 Note if secondary stack unit is used by compiler.
37264 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37265 ineffective elaborate all pragmas on non-visible packages (this
37266 happened when a renamed subprogram was called). Now the elaborate all
37267 always goes on the package containing the renaming rather than the one
37268 containing the renamed subprogram.
37270 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37271 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37273 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37274 has an Etype that references an E_String_Literal.
37275 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37276 always references an E_String_Literal_Subtype entity. This may not
37277 be true in the future.
37279 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37282 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37285 2004-01-05 Ed Falis <falis@gnat.com>
37287 * g-debuti.adb: Replaced direct boolean operator with short-circuit
37290 2004-01-05 Vincent Celier <celier@gnat.com>
37292 * bld.adb: Minor comment updates
37293 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37296 * make.adb (Gnatmake): Special process for files to compile/check when
37297 -B is specified. Fail when there are only foreign mains in attribute
37298 Main of the project file and -B is not specified. Do not skip bind/link
37299 steps when -B is specified.

37330 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37332 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37333 all attributes, including read-only attribute.

37344 based on the new naming scheme.
37346 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37347 scheme for the shared runtime libraries.
37350 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37352 (install-gnatlib): Do not create symlinks for shared libraries.
37353 (gnatlib-shared-default): Idem.
37354 (gnatlib-shared-dual-win32): New target. Not used for now as the
37355 auto-import feature does not support arrays/records.
37356 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37357 (gnatlib-shared-vms): Fix shared runtime libraries names.
37359 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37360 dependent runtime shared library name.
37362 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37364 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37367 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37369 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37370 protected objects when allocator has a subtype indication, not a
37371 qualified expression. Note that qualified expressions may have to be
37372 checked when limited aggregates are implemented.
37374 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37375 pure, emit warning.
37376 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37377 subprogram is imported, remove warning.
37379 2004-01-05 Geert Bosch <bosch@gnat.com>
37381 * s-poosiz.adb: Update copyright notice.
37382 (Allocate): Use Task_Lock to protect against concurrent access.

37421 * cstand.adb (Create_Standard): Change the way how the declaration of
37422 the Duration type is created (making it the same way as it is for all
37423 the other standard types).
37425 2003-12-17 Robert Dewar <dewar@gnat.com>
37427 * s-crtl.ads: Fix header format
37428 Change Pure to Preelaborate
37430 2003-12-17 Ed Schonberg <schonberg@gnat.com>
37432 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
37433 the expression type only if it is declared in the current unit.
37435 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37436 are universal and already analyzed, as can occur in constrained
37437 subcomponents that depend on discriminants, when one constraint is a
37440 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37441 type Any_Fixed is legal as the argument of a conversion, if only one
37442 fixed-point type is in context.
37444 2003-12-17 GNAT Script <nobody@gnat.com>
37446 * Make-lang.in: Makefile automatically updated

37453 2003-12-15 Vincent Celier <celier@gnat.com>
37455 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37456 (Gnatchop): Do not set failure status when reporting the number of
37459 2003-12-15 Doug Rupp <rupp@gnat.com>
37461 * s-ctrl.ads: New file.

37483 2003-12-11 Ed Falis <falis@gnat.com>
37485 * 5zinit.adb: Clean up.
37487 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37488 to __gnat_map_signal, imported from init.c to support
37489 signal -> exception mappings that depend on the vxWorks version.
37492 Created and exported __gnat_map_signal to support signal -> exception
37493 mapping that is dependent on the VxWorks version.
37494 Change mapping of SIGBUS from Program_Error to Storage_Error on VxWorks
37496 2003-12-11 Vasiliy Fofanv <fofanov@act-europe.fr>

37508 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
37510 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
37512 * sinfo.ads: Fix inconsistent example code in comment.
37514 2003-12-11 Robert Dewar <dewar@gnat.com>
37516 * a-tiinau.adb: Add a couple of comments
37518 * sem_ch3.adb: Minor reformatting
37521 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37522 Minor reformatting throughout
37524 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37526 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37527 bounds of a loop, create a separate block in order to generate proper
37528 cleanup actions to prevent memory leaks.
37530 * sem_res.adb (Resolve_Call): After a call to
37531 Establish_Transient_Scope, the call may be rewritten and relocated, in
37532 which case no further processing is needed.
37534 * sem_util.adb: (Wrong_Type): Refine previous fix.

37544 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37547 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37550 2003-12-08 Robert Dewar <dewar@gnat.com>
37552 * 7sintman.adb: Minor reformatting
37554 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37555 standard linker options to get standard libraries linked. We now plan
37556 to provide dummy versions of these libraries to match the appropriate
37557 configurable run-time (e.g. if a library is not needed at all, provide
37558 a dummy empty library).
37560 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37561 options (-L parameters and standard libraries). What we plan to do is
37562 to provide dummy libraries where the libraries are not required.
37564 * gnatbind.adb: Minor comment improvement
37566 2003-12-08 Javier Miranda <miranda@gnat.com>
37568 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37569 aggregate in the parent. Otherwise constants with limited aggregates
37570 are not supported. Add new formal to pass the component type (Ctype).
37571 It is required to call the corresponding IP subprogram in case of
37572 default initialized components.
37573 (Gen_Assign): In case of default-initialized component, generate a
37574 call to the IP subprogram associated with the component.
37575 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37576 of aggregate with default initialized components.
37577 (Has_Default_Init_Comps): Improve implementation to recursively check
37578 all the present expressions.
37580 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37581 to indicate that the initialization call corresponds to a
37582 default-initialized component of an aggregate.
37583 In case of default initialized aggregate with tasks this parameter is
37584 used to generate a null string (this is just a workaround that must be
37585 improved later). In case of discriminants, this parameter is used to
37586 generate a selected component node that gives access to the discriminant
37589 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37590 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37591 allocated aggregates with default-initialized components.
37593 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37594 the box notation is used in positional aggregates.

37611 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37612 Set the scanner to return ends of line and comments as tokens, if
37613 Store_Comments is True.
37614 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37615 comments are associated with these nodes. Store the node IDs in the
37617 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37619 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37620 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37621 current project. Call Tree.Restore afterwards. Set the various nodes
37622 for comment storage (Next_End, End_Of_Line, Previous_Line,
37625 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37626 defaulted to False.
37628 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37629 to False. When Truncated is True, truncate the string, never go to the
37631 (Write_End_Of_Line_Comment): New procedure
37632 (Print): Process comments for nodes N_With_Clause,
37633 N_Package_Declaration, N_String_Type_Declaration,
37634 N_Attribute_Declaration, N_Typed_Variable_Declaration,
37635 N_Variable_Declaration, N_Case_Construction, N_Case_Item.
37636 Process nodes N_Comment.
37638 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37639 without comments and there are some comments, set the flag
37640 Unkept_Comments to True.
37641 (Scan): If there are comments, set the flag Unkept_Comments to True and
37642 clear the comments.
37643 (Project_Node_Kind): Add enum values N_Comment_Zones, N_Comment
37644 (Next_End_Nodes: New table
37645 (Comment_Zones_Of): New function
37646 (Scan): New procedure; moved from Prj. Accumulate comments in the

37661 (Set_First_Comment_Before, Set_First_Comment_Before_End): New procedures
37662 (Set_Next_Comment): New procedure
37663 (Default_Project_Node): Associate comment before if the node can store

37669 * scng.ads, scng.adb (Comment_Is_Token): New Boolean global variable,
37670 defaulted to False.
37671 (Scan): Store position of start of comment. If comments are tokens, set
37672 Comment_Id and set Token to Tok_Comment when scanning a comment.
37673 (Set_Comment_As_Token): New procedure
37675 * sinput-p.adb: Update Copyright notice
37676 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan
37677 that no longer exists.
37679 2003-12-08 Javier Miranda <miranda@gnat.com>
37681 * sem_aggr.adb: Add dependence on Exp_Tss package
37682 Correct typo in comment
37683 (Resolve_Aggregate): In case of array aggregates set the estimated
37684 type of the aggregate before calling resolve. This is needed to know
37685 the name of the corresponding IP in case of limited array aggregates.
37686 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
37687 in case of default initialized array components.
37689 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited
37690 types. Required to give support to limited aggregates in generic
37693 2003-12-08 Ed Schonberg <schonberg@gnat.com>

37696 inlined body functions like an instantiation.
37697 (Decimal_Fixed_Point_Declaration): Do not set kind of first subtype
37698 until bounds are analyzed, to diagnose premature use of type.
37700 * sem_util.adb (Wrong_Type): Improve error message when the type of
37701 the expression is used prematurely.
37703 2003-12-08 GNAT Script <nobody@gnat.com>
37705 * Make-lang.in: Makefile automatically updated
37707 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
37709 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37710 they are automatically generated by Make-lang.in and cause nothing but
37711 maintenance troubles.
37713 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37715 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37724 Update copyright notice when appropriate.
37726 * 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
37729 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37730 to ensure that the kernel fills in the interrupted context structure
37731 before calling a signal handler, which is necessary to be able to
37732 unwind past it. Update the copyright notice.
37734 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37736 * a-elchha.ads: New file.
37738 * a-elchha.adb: New default last chance handler. Contents taken from
37739 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.
37741 * a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
37742 is moved to a-elchha.adb to provide a target-independent default last
37745 * Makefile.rtl: Add a-elchha.o
37747 * Make-lang.in (GNAT_ADA_OBJS, GNATBIND_OBJS): Add a-elchha.o.

37751 * exp_ch6.adb (Expand_Call): If the subprogram is inlined and is
37752 declared in an instance, do not inline the call if the instance is not
37753 frozen yet, to prevent order of elaboration problems.
37755 * sem_prag.adb: Add comments for previous fix.
37757 2003-12-05 Samuel Tardieu <tardieu@act-europe.fr>
37759 * g-table.adb: Use the right variable in Set_Item.

37768 * switch-c.adb (Scan_Front_End_Switches): Remove processing of
37769 -nostdlib. Not needed here after all.
37771 2003-12-03 Thomas Quinot <quinot@act-europe.fr>
37774 * adaint.h, adaint.c, g-os_lib.ads:
37775 Do not assume that the offset argument to lseek(2) is a 32 bit integer,
37776 on some platforms (including FreeBSD), it is a 64 bit value.
37777 Introduce a __gnat_lseek wrapper in adaint.c to allow for portability.

39190 Remove the test against being in No_Run_Time_Mode before generating a
39191 call to Register_Tag. It is redundant with the test against the
39192 availability of the function Register_Tag.

41129 * sem_util.adb: Use new Duplicate_Subexpr functions
41132 (Eval_Indexed_Component): This is the place to call
41133 Constant_Array_Ref and to replace the value. We simply merge
41134 the code of this function in here, since it is now no longer

41370 C front end but not used, or used only to permit the compiler
41373 2002-02-07 Richard Henderson <rth@redhat.com>
41375 * adaint.c (__gnat_to_gm_time): First arg is int, not time_t.

41378 2002-01-30 Richard Henderson <rth@redhat.com>
41380 * trans.c (tree_transform) [N_Loop_Statement]: Use
41381 expand_exit_loop_top_cond.
41383 2001-12-23 Richard Henderson <rth@redhat.com>

41395 rule which was mandated by code generation issues.
41397 * gnat-style.texi (header): Add @dircategory, @direntry.
41398 (title page): Remove date.
41399 (general) Add @./@: where approriate, and two spaces after the
41400 full stop at the end of a sentence. Use @samp markup when
41401 referring concrete lexical entities (keywords, attribute names
41402 etc.), and @syntax for ARM grammar elements. Use @r for English
41403 text in comments. Use @emph for emphasis. Change "if-statements"
41404 etc. to "if statements" (without @samp). Break long lines. Make
41405 casing of section names consistent.
41406 (Identifiers): Use @samp markup for variable names.
41407 (Comments): Use @samp markup for comment characters. Line-end
41408 comments may follow any Ada code, not just statements. Fix
41409 misspelling of "Integer" as "integer".

41415 2001-12-22 Florian Weimer <fw@deneb.enyo.de>
41417 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41418 function approach did not work well because of a side effect (the
41419 function call could reallocate the table which was being indexed
41420 using its result). Fixes ada/4851.
41422 2001-12-19 Robert Dewar <dewar@gnat.com>
41424 * bindgen.adb: Minor reformatting

41450 * prj-env.ads: Minor reformatting
41452 * switch.adb: Minor reformatting. Do proper raise of Bad_Switch if
41453 error found (there were odd exceptions to this general rule in
41454 -gnatec/-gnatem processing)
41456 2001-12-19 Olivier Hainque <hainque@gnat.com>
41458 * raise.c (__gnat_eh_personality): Exception handling personality
41459 routine for Ada. Still in rough state, inspired from the C++ version
41460 and still containing a bunch of debugging artifacts.
41461 (parse_lsda_header, get_ttype_entry): Local (static) helpers, also
41462 inspired from the C++ library.
41464 * raise.c (eh_personality): Add comments. Part of work for the GCC 3
41465 exception handling integration.
41467 2001-12-19 Arnaud Charlet <charlet@gnat.com>

41473 interrupt handling files.
41474 (RAVEN_MOD): Removed, no longer needed.
41476 2001-12-19 Robert Dewar <dewar@gnat.com>
41478 * a-ngelfu.adb: Remove ??? comment for inappropriate Inline_Always
41479 Add 2001 to copyright date
41481 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41482 need to force universal inlining for these cases.
41484 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41486 * s-taprob.adb: Minor clean ups so that this unit can be used in

41787 2001-12-17 Laurent Pautet <pautet@gnat.com>
41790 Fix comment of Shutdown_Socket and Close_Socket. These functions
41791 should not fail silently because if they are called twice, this
41792 probably means that there is a race condition in the user program.

43192 * types.adb (Hex): Use lowercase for the letter part.
43194 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43195 for a word. This is currently used only for CRC. In previous version,
43196 the checksum was using a representation with all letter being
43197 upper-case. With the new implementation (using CRC) we do not remove
43198 the 32th bit of the CRC, so we can have an upper-case starting letter
43199 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43200 It is ambigous since the CRC was optional and could be followed by
43201 options like EB, EE. So now this routines uses lower-case letter for
43202 the hexadecimal representation. Strange enough only lower case letters
43203 where checked in Scan_ALI (even if this was not a possible case).
