2064 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2065 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2066 N_Identifier. This was interfering with other cases that are rewritten

4160 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4161 convention from its base type, do not set the type to that of integer,

4226 the visible part of the spec of a remote types unit.

4228 New local subprogram Is_Valid_Remote_Object_Type, replaces
4229 Is_Recursively_Limited_Private.
4230 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4231 non-controlling formals (and the return type, even though this is not
4232 explicit in the standard) must support external streaming.

4234 as above for of RAS types and RCI subprograms. (The return type is not

4239 * sem_util.ads, sem_util.adb
4240 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4241 Is_Remote_Call_Interface to identify RACW types in a stable and
4242 consistent way. We used to rely in this predicate on the privateness of
4243 the designated type and its ancestors, but depending on the currently
4244 visible private parts, this caused false negatives. We now uniformly
4245 rely on checks made at the point where the RACW type is declared.

4259 Add missing escaping of all-caps word 'CPP' in error messages.
4260 (Build_Discriminated_Subtype): Do not inherit representation clauses
4261 from parent type if subtype already carries them, because they are
4262 inherited earlier during derivation and already include those that may
4263 come from a partial view.
4265 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4266 Check the declarations of a subprogram body for proper deferred

4300 (Add_One_Interp): Ignore any interpretation that is a primitive
4301 operation of an RACW stub type (these primitives are only executed
4302 through dispatching, never through static calls).
4303 (Collect_Interps): When only one interpretation has been found, set N's
4304 Entity and Etype to that interpretation, otherwise Entity and Etype may
4305 still refer to an interpretation that was ignored by Add_One_Interp,
4306 in which case would end up with being marked as not overloaded but with
4307 an Entity attribute not pointing to its (unique) correct interpretation.
4309 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4312 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4322 (Print_Itype): Do not modify the sloc of the component type of a
4323 (packed) array itype, because it is an unrelated type whose source
4324 location is independent of the point of creation of the itype itself.

4363 2008-05-20 Arnaud Charlet <charlet@adacore.com>

4366 equivalent representation, but has the advantage of allowing
4367 compilation of this file under 64 bits platforms.
4369 * s-os_lib.adb (Normalize_Pathname): Mark Cur_Dir constant.
4371 * s-osinte-irix.ads: (Alternate_Stack_Size): Add dummy declaration.

8567 WITH clause on a private sibling.
8568 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8569 child unit is a renaming, create an implicit with_clause on that

8672 perform subtype conformance between the formals of the current entry
8673 and those of the target interface primitive.
8674 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8675 Timed_Entry_Call): Analyze the triggering statement as the first step of
8676 the processing. If this is a dispatching select, postpone the analysis
8677 of all select statements until the Expander transforms the select. This

8679 replicated some of the select statements. In case the Expander is
8680 disabled, perform regular analysis.
8681 (Check_Triggering_Statement): New routine.
8682 (Analyze_Requeue): Exclude any interpretations that are not entries when
8683 checking overloaded names in a requeue. Also test type conformance for
8684 matching interpretations rather than requiring subtype conformance at

8692 for the defaulted actual.
8694 2007-12-13 Geert Bosch <bosch@adacore.com>
8696 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9278 Add support for parsing multiple array index types info, or
9279 multiple inherited interfaces info. This information cannot be stored
9280 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9296 Dismukes). After this patch there is no need to perform any
9297 additional management on these nodes in Expand_Interface_Actuals.
9299 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9300 that handles use of 'Access and 'Unchecked_Access applied to
9301 actuals covering interface types. Such code is now
9302 centralized in Expand_N_Attribute_Reference.
9304 2007-10-15 Ed Schonberg <schonberg@adacore.com>

9307 of tagged types whose ultimate ancestor is a CPP type.

9346 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9347 used by VxWorks targets to have access to task-specific data and be
9348 able to extract the stack boundaries for stack checking.

9392 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9393 association for an access component, add an association with null as
9394 the expression. Remove testing for array subtypes and the setting in
9395 that case of Ctyp to the array component type, which prevented proper
9396 inclusion of an association for null-initialized arrays. Collapse
9397 condition that tests for array subtypes into just a test of
9398 Is_Partially_Initialized_Type (which already covers arrays anyway).

9552 type of file_info_ptr parameter.
9553 If mapped location support is enabled, create the isomorphic mapping
9554 between source files and line maps.
9555 (Sloc_to_locus): If mapped location support is enabled, translate
9556 source location into mapped location.
9557 (annotate_with_node): Rename into set_expr_location_from_node.

9584 Add a section on leap seconds control along with two entities used to
9585 enable and disable leap seconds support. The array Leap_Second_Times is
9586 now constant and contains hard time values pre-generated. Remove
9587 all elaboration code used to populate the table of leap seconds.

9648 Eric Botcazou <ebotcazou@adacore.com>
9651 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9652 indirection added to the HT_Link component of the TSD. This is required
9653 to statically allocate the TSD.
9656 Minor reordering of the declarations in the private part. Required to
9657 add a level of indirection to the contents of the TSD component HT_Link.
9658 This is required to statically allocate the TSD.
9660 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9661 Is_Statically_Allocated set from constant objects.
9662 Do not make exported constants created by the compiler volatile.
9663 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9666 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9667 before returning them.
9669 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9670 public part of the package.
9671 (Make_DT): Move HT_Link component out of the TSD record. For this
9672 purpose Make_DT now declares a separate object that stores the
9673 HT_Link value, and initializes the TSD component with the address
9674 of this new object. The addition of this level of indirection is
9675 required to statically allocate the TSD because the TSD cannot
9676 have variable components.
9677 (Expand_Interface_Conversion): Improve the expanded code.
9678 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9680 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9681 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9682 if we are building static dispatch tables then we must not generate
9683 extra code to register the primitive because the dispatch table will
9684 be built at the end of the library package; otherwise we notify that
9685 we cannot build the static dispatch table.
9687 2007-09-26 Robert Dewar <dewar@adacore.com>
9689 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9704 for thunks associated with interface types.
9706 * einfo.ads: Improve documentatation of Is_Internal
9707 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9708 associated with interface types.
9709 Extensive comment fixes regarding flags that appear in all entities. The
9710 documentation is now consistent for all such flags (there were a number
9711 of errors in the documentation in this regard).
9713 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9715 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9716 of these procedures are passed a function call that already has
9717 build-in-place actuals (testing new flag
9718 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9719 the case where processing continues.
9720 (Expand_Call): If the call is generated from a thunk body then we
9721 propagate the extra actuals associated with the accessibility
9722 level of the access type actuals.
9724 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9725 of each extra formal of a protected operation to reference the
9726 corresponding extra formal of the subprogram denoted by the
9727 operation's Protected_Body_Subprogram.
9729 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9730 N_Function_Call nodes.
9732 2007-09-26 Robert Dewar <dewar@adacore.com>
9734 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9736 * debug.adb: Add d.s flag.

9740 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9741 debug variable so that it won't be initialized when pragma
9742 Initialize_Scalars is in effect.
9744 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9746 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9747 initialization of a full view. This is moved to
9748 Analyze_Package_Specification.
9750 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9751 preelaborable initialization of a full view in entity loop.
9752 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9753 its child units are use-visible only if they are visible child units.
9755 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9756 whether an expression can be used within a type declaration that
9757 requires preelaborable init.
9758 (Check_Components): Replace inline code that does partial checking for
9759 preelaborable default expressions with call to
9760 Is_Preelaborable_Expression.
9761 (Has_Preelaborable_Initialization): In the case of a generic actual
9762 subtype, (that is, Is_Generic_Actual is True), return the result of
9763 applying Has_Preelaborable_Initialization to the generic actual's base
9766 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9768 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9769 call to Jan_1_Day _Of_Week to optimize its performance.
9770 (Is_Leap): Move the routine to the scope of Week_In_Year.
9771 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9772 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9773 avoids calling Time_Of and Split, thus making it more efficent.
9774 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9776 * g-calend.ads (Week_In_Year): Change comment to reflect new
9779 2007-09-26 Emmanuel Briot <briot@adacore.com>

9782 Command_Line): New types
9783 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9784 support for defining how switches can be grouped on a command line (as
9785 is the case for -gnatw... for GNAT), and how simple switches can be
9786 used as aliases for more complex switches (-gnatwa is same as
9788 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9789 (Start, Current_*): New subprograms
9790 Added support for parsing an array of strings in addition to the real
9792 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9793 be moved from the body to the private part of the spec.
9794 (*): All subprograms now have an extra parameter with default value to
9795 specify which parser should be used. For backward compatibility, it
9796 defaults to parsing the command line of the application. They were also
9797 modified to properly handle cases where each of the argument does not
9798 start at index 1 (which is always true for Ada.Command_Line, but not
9799 when processing any Argument_List).
9800 (Free): New subprogram
9801 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9802 Argument): New subprograms
9803 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9804 special characters like ':', '=',... are now handled in a single place,
9805 which makes the code more extensible eventually.
9806 (Getopt, Full_Switch): When the switch was returned as part of the
9807 special character '*', make sure it is prepended by the switch character
9808 ('-' in general), so that the application knows whether "foo" or "-foo"
9809 was specified on the command line.
9811 2007-09-26 Florian Villoing <villoing@adacore.com>
9813 * g-dirope.adb (Remove_Dir): In case we are removing directories
9814 recursively, make sure that if an exception is raised during the
9815 processing, the current working directory is reset to its initial
9816 value before propagating the exception.
9818 2007-09-26 Vincent Celier <celier@adacore.com>
9820 * gnatbind.adb: If there are several ALI files specified and there is
9821 a main program to bind, the first ALI is expected to contain the main
9822 subprogram and the names of the binder generated files will be derived
9823 from the first ALI file name.
9824 (Gnatbind): Fix insertion character in invocation of Error_Msg
9826 2007-09-26 Vincent Celier <celier@adacore.com>
9828 * gnatcmd.adb (Check_Files): Do not include sources that have been
9829 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9831 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9833 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9834 information about each of its index types, following the type
9835 reference for its component type.
9837 2007-09-26 Vincent Celier <celier@adacore.com>
9839 * make.adb: (Kill): New procedure (__gnat_kill imported)

9846 sources, so that the correct paths will be found.
9848 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9850 2007-09-26 Vincent Celier <celier@adacore.com>
9852 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9854 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9855 Replace components Compiler_Min_Options and Binder_Min_Options with
9856 Compiler_Required_Switches and Binder_Required_Switches in record
9858 Remove components Default_Language and Config in Project_Tree_Data,
9861 * prj-attr.adb: New attributes Required_Switches (<language>) in
9862 packages Compiler and Binder.
9864 * prj-nmsc.adb: Major rewrite of the processing of configuration
9865 attributes for gprbuild. No impact on GNAT tools.
9867 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

9873 (Process): Implementation now uses the two new procedures
9875 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9876 from the project config, not the tree config that no longer exists.

9899 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9901 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9902 ancestor of the derived type, the operations are inherited from the
9903 primary dispatch table of the parent.
9904 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9905 when the context is an explicit type conversion.
9907 2007-09-26 Ed Schonberg <schonberg@adacore.com>

10207 potentially be called.
10208 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10209 body for 'Output when the type is abstract (only the creation of the
10210 body for 'Input is excluded when the type is abstract).
10211 (Stream_Operation_OK): Add an additional condition in the return
10212 statement, so that False will be returned for TTS_Stream_Input if the
10213 associated tagged type is an abstract extension. Add comments for
10215 (Expand_N_Object_Declaration): For the case of a shared passive
10216 variable, insert init proc call only after the shared variable
10217 procedures have been processed, because the IP call needs to undergo
10218 shared passive variable reference expansion, which requires these

10231 type, retrieve its value from the aggregate itself, where it must have
10234 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10235 to remove other spurious ambiguities on arithmetic operations involving
10236 literals and addresses, on systems where Address is a visible integer
10237 type, when the operator is called in functional notation.
10238 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10239 is legal when the types match, even if the operation is currently
10242 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10244 * sem_ch12.adb (Build_Local_Package): A formal package with no
10245 associations is legal if all formals have defaults. It is not

10390 that its encoded name is properly qualified.
10392 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10393 occurring in the list of entities to qualify, and do not attempt to
10394 traverse an entity list in that case. Variables associated with

10419 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10420 concatenations of string literals into a single literal, in order to
10421 avoid very deep recursion in the front end, which was causing stack
10424 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10425 string, and the right operand is a string literal (the case of "" &
10426 "..."), optimize by avoiding copying the right operand -- just use the
10427 value of the right operand directly.
10429 * stringt.adb (Store_String_Chars): Optimize by growing the
10430 String_Chars table all at once, rather than appending characters one by
10432 (Write_String_Table_Entry): If the string to be printed is very long,
10433 just print the first few characters, followed by the length. Otherwise,
10434 doing "pn(n)" in the debugger can take an extremely long time.
10436 * sem_prag.adb (Process_Interface_Name): Replace loop doing

10457 flag, for effiency. It is called when analyzing arithmetic operators
10458 and also for actuals in calls that are universal_integers. The flag is
10459 set for the predefined type address, and for any type or subtype
10462 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10463 Universal_Integer, when the formal is a descendent of address and the
10464 call appears in user code.

10531 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10532 associated with Standard_Debug_Renaming_Type, to be used as the type of
10533 the special variables whose names provide debugger encodings for
10534 renaming declarations.
10536 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10537 (Set_Debug_Renaming_Link): Change to set Node25.

10544 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10545 and literal with creation of a variable of type
10546 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10547 and the entity of the renaming declaration.
10548 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10549 part of the name of a variable that has a Debug_Renaming_Link.
10551 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10552 special type to be associated with variables that provide debugger

10557 Javier Miranda <miranda@adacore.com>
10559 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10560 ancestor part given by an aggregate to test for an unchecked conversion,
10561 since this can occur in some cases when the ancestor part is a function
10562 call, and we don't want to fall into the recursive call to this
10563 procedure in that case.
10565 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10566 stream attributes on limited types to account for user-specified
10567 attributes as well as whether Input (resp. Output) becomes available
10568 due to Read (resp. Write) being available for the type. Change Boolean
10569 variable to the more accurate name
10570 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10571 double-"not" predicate at beginning of return statement to more
10572 understandable form.
10574 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10575 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10576 in a block statement and use that as the first statement of the
10577 expanded return rather than incorrectly using the handled sequence as
10578 the first statement.
10580 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10581 operation, generate an explicit freeze node for it rather than
10582 generating extra formals, to ensure that gigi has the proper order of
10583 elaboration for anonymous subtypes in the signature of the subprograms.
10584 (Build_In_Place_Formal): Move assertion to beginning of loop.
10585 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10588 applied to a function call (occurs for some cases of 'Input).
10590 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10591 2005, generate an extended return statement enclosing the result object
10594 * freeze.adb (Freeze_Record_Type): Extend the current management of
10595 components that are access type with an allocator as default value: add
10596 missing support to the use of qualified expressions of the
10597 allocator (which also cause freezing of the designated type!)
10598 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10599 dispatching operation, since extra formals may be needed by calls to
10600 build-in-place functions (such as stream 'Input).
10602 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10603 formals for 'Constrained and accessibility level in the case of a
10604 predefined dispatching operation.
10606 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10607 point, no need to find the parent node.
10609 2007-08-16 Javier Miranda <miranda@adacore.com>
10611 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10612 and entry barriers.
10614 2007-08-16 Javier Miranda <miranda@adacore.com>
10616 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10617 is not really required and can introduce regression with the debugger.
10618 The original problem is fixed with the patch written for checks.adb.
10620 2007-08-16 Thomas Quinot <quinot@adacore.com>
10622 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10629 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10630 Including_Non_Switch set to False.
10632 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10633 parameter Including_Non_Switch, defaulted to True. When
10634 Including_Non_Switch is False, options that are not switches and
10635 appear as relative path are not converted to absolute paths.
10637 2007-08-16 Nicolas Roche <roche@adacore.com>
10639 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10650 from the immediate ancestor of Main_Unit_Entity.
10651 (Install_Limited_Withed_Unit): Do not install the limited view of
10652 package P if P is reachable through an ancestor chain from package C
10653 and C also has a with clause for P in its body.
10654 (Has_Limited_With_Clause): New routine.
10655 (Has_With_Clause): New routine.
10657 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10659 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10660 generic for an enclosing instance is a global reference, even though
10661 its scope is the enclosing instance.
10663 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10664 Javier Miranda <miranda@adacore.com>
10666 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

10670 Make sure Has_Complex_Representation is inherited by derived type.
10672 2007-08-16 Robert Dewar <dewar@adacore.com>

10677 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10679 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10680 implements an operation inherited from a progenitor interface, verify
10681 that they are subtype-conformant.

10684 Bob Duff <duff@adacore.com>
10685 Nicolas Setton <setton@adacore.com>
10687 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10688 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10689 the statement which is being resolved comes from a predefined library
10690 unit, all non-predefined library interpretations are skipped.
10691 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10692 but the "&" is user defined, give an error, because the folding would

10696 the parser has folded a long sequence of concatenations of string
10699 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10700 and "JMP_BUF" variables as artificial.
10701 (N_String_Literal): Do not use alloca for very long string literals. Use
10702 xmalloc/free instead. Otherwise the stack might overflow.
10704 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the

10749 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10750 Suppress unmodified in-out parameter warning in some cases
10751 This patch is a also fairly significant change to the way suppressible
10752 checks are handled.
10754 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10755 needed for access to concurrent record types generated by the expander.
10756 (Generate_Range_Check): When generating a temporary to capture the
10757 value of a conversion that requires a range check, set the type of the
10758 temporary before rewriting the node, so that the type is always
10759 properly placed for back-end use.
10760 (Apply_Float_Conversion_Check): Handle case where the conversion is
10762 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10778 (Expand_N_Type_Conversion): Test for the case of renamings of access
10779 parameters when deciding whether to apply a run-time accessibility
10781 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10782 aggregate code before allocator, and ahead of declaration for
10783 temporary, to prevent access before elaboration when the allocator is
10784 an actual for an access parameter.
10785 (Expand_N_Type_Conversion): On an access type conversion involving an
10786 access parameter, do not apply an accessibility check when the
10787 operand's original node was an attribute other than 'Access. We now
10788 create access conversions for the expansion of 'Unchecked_Access and
10789 'Unrestricted_Access in certain cases and clearly accessibility should
10790 not be checked for those.
10792 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10793 includes a type conversion of a packed component that has been expanded,
10794 recover the original expression for the object, and use this expression
10795 in the post-call assignment statement, so that the assignment is made
10796 to the object and not to a back-end temporary.
10797 (Freeze_Subprogram): In case of primitives of tagged types not defined
10798 at the library level force generation of code to register the primitive
10799 in the dispatch table. In addition some code reorganization has been
10800 done to leave the implementation clear.
10801 (Expand_Call): When expanding an inherited implicit conversion,
10802 preserve the type of the inherited function after the intrinsic
10803 operation has been expanded.
10805 * exp_ch2.ads, exp_ch2.adb
10806 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10807 of an entry formal appearing in an assignment statement does not assign
10809 (Expand_Current_Value): Instead of calling a routine to determine
10810 whether the prefix of an attribute reference should be optimized or
10811 not, prevent the optimization of such prefixes all together.
10813 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10814 component whose prefix is known to be of an access type is an implicit
10815 dereference and does not assign to the prefix.
10817 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10818 Robert Dewar <dewar@adacore.com>
10820 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10821 itype is visited, make an entry into table to link associated node and
10823 Add comments and correct harmless error in Build_NCT_Hash_Tables
10824 (Array_Aggr_Subtype): Associate each itype created for an index type to
10825 the corresponding range construct, and not to the aggregate itself. to

10831 treatment of limited views uniform for all visible declarations in a
10832 limited_withed package.
10833 (New_Copy_Tree): If hash table is being used and itype is visited,
10834 make an entry into table to link associated node and new itype.
10835 (Resolve_Record_Aggregate): Do not add an others box association for a
10836 discriminated record component that has only discriminants, when there
10837 is a box association for the component itself.

10886 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10887 generation of a freezing node to ensure proper management of null
10888 excluding access types in the backend.
10889 (Create_Extra_Formals): Test base type of the formal when checking for
10890 the need to add an extra accessibility-level formal. Pass the entity E
10891 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10892 originally being done in a couple of cases), to ensure that the
10893 Extra_Formals list gets set on the entity E when the first entity is
10895 (Conforming_Types): Add missing calls to Base_Type to the code that
10896 handles anonymous access types. This is required to handle the
10897 general case because Process_Formals builds internal subtype entities
10898 to handle null-excluding access types.
10899 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10900 functions that need it, even when not marked Requires_Overriding.
10901 Improve warnings for in out parameters
10902 (Analyze_Function_Return): Warn for disallowed null return
10903 Warn on return from procedure with unset out parameter
10904 Ensure consistent use of # in error messages
10905 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10906 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10907 the implicit conversion of the expression done for anonymous access
10908 types. This is required to generate the code of the null excluding
10909 check (if required).
10911 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10912 A formal parameter is never publicly referenceable outside of its body.
10913 (Check_References): For an unreferenced formal parameter in an accept
10914 statement, use the same warning circuitry as for subprogram formal
10916 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10917 Output_Unreferenced_Messages, containing the part of that routine that
10918 is now reused for entry formals as described above.
10919 (Goto_Spec_Entity): New function
10920 (Check_References): Do not give IN OUT warning for dispatching operation
10921 Improve warnings for in out parameters

10928 Javier Miranda <miranda@adacore.com>
10929 Gary Dismukes <dismukes@adacore.com>
10931 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10932 (Expand_N_Attribute_Reference): Further unify the handling of the
10933 three forms of access attributes, using common code now for all three
10934 cases. Add a test for the case of applying an access attribute to
10935 an explicit dereference when the context is an access-to-interface
10936 type. In that case we need to apply the conversion to the prefix
10937 of the explicit dereference rather than the prefix of the attribute.
10938 (Attribute_Version, UET_Address): Set entity as internal to ensure
10939 proper dg output of implicit importation.
10940 (Expand_Access_To_Type): Removed.
10941 (Expand_N_Attribute_Reference): Merge the code from the three cases
10942 of access attributes, since the processing is largely identical for
10943 these cases. The substantive fix here is to process the case of a
10944 type name prefix (current instance case) before handling the case
10945 of interface prefixes.

10950 Robert Dewar <dewar@adacore.com>
10952 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10953 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10954 type that is an anonymous access to controlled object, establish
10955 an associated finalization chain to avoid corrupting the global
10956 finalization list when a dynamically allocated object designated
10957 by such a component is deallocated.
10958 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10959 functions that need it, even when not marked Requires_Overriding.
10960 (Initialize_Tag): Replace call to has_discriminants by call to
10961 Is_Variable_Size_Record in the circuitry that handles the
10962 initialization of secondary tags.
10963 (Is_Variable_Size_Record): New implementation.
10964 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10965 Suppress_Initialization pragma for a derived type.
10966 (Is_Variable_Size_Record): New subprogram.
10967 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10968 initial version of this routine and also fixes problems causing
10969 incomplete initialization of the table of interfaces.
10970 (Build_Init_Procedure): Improve the generation of code to initialize the
10971 the tag components of secondary dispatch tables.
10972 (Init_Secondary_Tags): New implementation that simplifies the previous
10973 version of this routine.
10974 (Make_DT): Add parameter to indicate when type has been frozen by an
10975 object declaration, for diagnostic purposes.
10976 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10977 diagnose attemps to freeze a subprogram when some untagged type of its
10978 profile is a private type whose full view has not been analyzed yet.
10979 (Freeze_Array_Type): Generate init proc for packed array if either
10980 Initialize or Normalize_Scalars is set.
10981 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10982 constructing the new profile, copy the null_exclusion indicator for each
10983 parameter, to ensure full conformance of the new body with the spec.
10985 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10986 Create wrappers for constructor functions that need it, even when not
10987 marked Requires_Overriding.
10988 (Covers): Handle properly designated types of anonymous access types,
10989 whose non-limited views are themselves incomplete types.
10990 (Add_Entry): Use an entity to store the abstract operation which hides
10992 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

10997 (Has_Compatible_Type): Remove machinery that skips interpretations if
10998 they are labeled as potentially hidden by an abstract operator.
10999 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11000 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11001 (Write_Overloads): Output the abstract operator if present.
11002 (Add_Entry): Before inserting a new entry into the interpretation table
11003 for a node, determine whether the entry will be disabled by an abstract

11020 types declared in the declarative part of a nested package body or in
11021 the proper body of a stub.
11022 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11023 of the same dispatch table slot to renamed primitives.
11024 (Make_Select_Specific_Data_Table): Handle private types.
11025 (Tagged_Kind): Handle private types.
11026 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11027 output of implicit importation and exportation.
11028 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11029 first formal of the thunk is always associated with the controlling
11030 type. In addition perform the following code cleanup: remove formal
11031 Thunk_Alias which is no longer required, cleanup evaluation of the
11032 the controlling type, and update the documentation.
11033 Replace occurrence of Default_Prim_Op_Count by
11034 Max_Predef_Prims. Addition of compile-time check to verify
11035 that the value of Max_Predef_Prims is correct.
11036 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11037 (Make_DT): Add parameter to indicate when type has been frozen by an
11038 object declaration, for diagnostic purposes.
11039 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11040 construction of statically allocated dispatch tables.
11041 (Make_DT): In case of library-level tagged types export the declaration
11042 of the primary tag. Remove generation of tags (now done by Make_Tags).
11043 Additional modifications to handle non-static generation of dispatch
11044 tables. Take care of building tables for asynchronous interface types
11045 (Make_Tags): New subprogram that generates the entities associated with
11046 the primary and secondary tags of Typ and fills the contents of Access_
11047 Disp_Table. In case of library-level tagged types imports the forward
11048 declaration of the primary tag that will be declared later by Make_DT.
11049 (Expand_Interface_Conversion): In case of access types to interfaces
11050 replace an itype declaration by an explicit type declaration to avoid
11051 problems associated with the scope of such itype in transient blocks.

11054 Ed Schonberg <schonberg@adacore.com>
11055 Javier Miranda <miranda@adacore.com>
11057 * exp_util.ads, exp_util.adb:
11058 This patch replaces a number of occurrences of explicit tests for N_Null
11059 with calls to Known_Null. This improves tracking of null values, since
11060 Known_Null also catches null constants, and variables currently known to
11061 be null, so we get better tracking.
11062 (Ensure_Defined): create an itype reference only in the scope of the
11064 (Side_Effect_Free): A selected component of an access type that
11065 denotes a component with a rep clause must be treated as not
11066 side-effect free, because if it is part of a linked structure its
11067 value may be affected by a renaming.
11068 (Expand_Subtype_From_Expr): For limited objects initialized with build
11069 in place function calls, do nothing; otherwise we prematurely introduce
11070 an N_Reference node in the expression initializing the object, which
11071 breaks the circuitry that detects and adds the additional arguments to
11072 the called function. Bug found working in the new patch for statically
11073 allocated dispatch tables.
11074 (Is_Library_Level_Tagged_Type): New subprogram.
11075 (Remove_Side_Effects): If the expression of an elementary type is an
11076 operator treat as a function call.
11077 (Make_Literal_Range): If the index type of the array is not integer, use
11078 attributes properly to compute the constraint on the resulting aggregate
11081 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11082 class-wide type whose base type is an incomplete private type, leave
11083 class-wide type unfrozen so that freeze nodes can be generated
11084 properly at a later point.
11085 (Freeze_Entity, array case): Handle case of pragma Pack and component
11086 size attributre clause for same array.

11146 source dirs are not known.
11147 (Check_Ada_Name): Allow all identifiers that are not reserved words

11733 derived type with interface progenitors use the analyzed formal as the
11734 parent of the actual, to create renamings for all the inherited
11735 operations in Derive_Subprograms.
11736 (Collect_Previous_Instances): new procedure within of
11737 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11738 unit being loaded, to ensure that the generation of global symbols is
11739 consistent in different compilation modes.
11740 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11741 takes progenitor types into account.
11742 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11743 traversing over the primitives of the formal and actual types to locate
11744 any abstract subprograms of the actual type that correspond to a
11745 nonabstract subprogram of the formal type's ancestor type(s), and issue
11746 an error if such is found.
11747 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11748 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11749 Remove bogus guard around calls to Inherit_Context.
11750 (Reset_Entity): If the entity is the selector of a selected component
11751 that denotes a named number, propagate constant-folding to the generic
11752 template only if the named number is global to the generic unit.
11753 (Set_Instance_Env): Only reset the compilation switches when compiling
11754 a predefined or internal unit.
11756 2007-08-14 Ed Schonberg <schonberg@adacore.com>
11758 * sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
11759 parameter to determine whether operation applies to the prefix.
11760 (Complete_Object_Operation): If actual has an access type and
11761 controlling formal is not an in_parameter, reject the actual if it is
11762 an access_to_constant type.
11763 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11764 type, the candidate operations are found in the scope of declaration of
11765 the type, because the type has no primitive subprograms.
11766 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11767 a private extension, only examine visible components before trying to
11768 analyze as a prefixed call.
11769 Change Entity_List to Type_To_Use, for better readability.
11770 (Has_Fixed_Op): Use base type when checking whether the type of an

11778 * sem_cat.ads, sem_cat.adb (Has_Stream_Attribute_Definition): New
11779 formal At_Any_Place indicating, when True, that we want to test for
11780 availability of the stream attribute at any place (as opposed to the
11781 current visibility context only).
11782 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11783 purpose of enforcing E.2.2(8) only if it is not available at any place.
11784 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11785 when checking the legality of an extension aggregate in a preelaborable
11786 package. Treat the literal null as a valid default expression in a
11787 component declaration for a type with preelaborable initialization.
11788 A limited interface is a legal progenitor for the designated type of a
11789 remote access to class-wide type.

11803 views that are themselves incomplete types.
11804 Handle interfaces visible through limited-with clauses.
11805 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11806 subprogram generic actual for which we have generated a renaming.
11807 Warn when the renaming introduces a homonym of
11808 the renamed entity, and the renamed entity is directly visible.

11819 when the type of the interpretation matches that of the context.
11820 (Resolve): When looping through all possible interpretations of a node,
11821 do not consider those that are hidden by abstract operators.
11822 (Resolve_Actuals): When verifying that an access to class-wide object
11823 is an actual for a controlling formal, ignore anonymous access to
11824 subprograms whose return type is an access to class_wide type.
11825 (Resolve_Slice): If the prefix of the slice is a selected component
11826 whose type depends on discriminants, build its actual subtype before
11827 applying range checks on the bounds of the slice.
11828 (Valid_Conversion): In an instance or inlined body, compare root types,
11829 to prevent anomalies between private and public views.
11830 (Resolve): Improve error message for ambiguous fixed multiplication
11831 expressions that involve universal_fixed multiplying operations.

11849 extraneous layer of Any wrapping for member label.
11850 (Expand_Receiving_Stubs_Bodies): For an RCI package body that has
11851 elabration statements, register the package with the name server
11852 at the beginning, not at the end, of the elaboration statements so
11853 that they can create remote access to subprogram values that designate
11854 remote subprograms from the package.

13016 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
13017 (Check_Nested_Access): New procedure.
13018 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
13019 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13020 (Related_Interface): New attribute. Present in dispatch table pointer
13021 components of records. Set to point to the entity of the corresponding
13023 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13024 (Original_Access_Type): Remove, not needed.
13025 (Root_Type): Handle properly subtypes of class-wide-types.
13028 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13029 class-wide types visible through limited-with clauses.
13030 (Try_Primitive_Operation): When examining all primitive operations of a
13031 tagged type, do not consider subprograms labeled as hidden unless they
13032 belong to a private generic type with a tagged parent.
13033 (Try_Object_Operation): Extensive rewriting, to handle properly various
13034 overloading cases, when several ancestors may have class-wide operations
13035 that are possible candidates, and when the overloaded functions return
13036 array types and have defaulted parameters so that the call may be
13037 interpreted as an indexing.
13038 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13039 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13040 successive actuals before analyzing the call itself.
13041 (Try_Primitive_Operation): A primitive operation is compatible with the
13042 prefix if the prefix has a synchronized type and the type of the formal
13043 is its corresponding record, as can be the case when the primitive
13044 operation is declared outside of the body of the type.
13045 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13046 perform homonym traversal, looking for class-wide operation matches
13047 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13048 access parameters are now restricted to anonymous access types.
13049 (Mark_Allocator): An allocator with a discriminant association parent is
13051 (Try_One_Prefix_Interpretation): If the type of the object is
13052 incomplete, as can be happen when it is a limited view obtained through
13053 a limited_with_clause, the selected component is not part of a prefixed
13055 (Complete_Object_Operation): Diagnose properly an object that is not
13056 aliased when the corresponding controlling formal is an access
13058 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13059 ambiguous calls in prefixed notation, where two primitives differ only
13060 in that the controlling argument of one is an access parameter.
13062 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13063 whether a function that returns an unconstrained type can be inlined.
13064 (Process_Formals): Diagnose properly the illegal use of an incomplete
13065 type in the profile of an access_to_subprogram declaration.
13066 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13067 operations are attached to the corresponding record.
13068 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13069 When processing a primitive of a concurrent type which implements an
13070 interface change the type of all controlling formals to that of the
13071 corresponding record type.
13072 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13073 to determine the tagged type to which a primitive belongs.
13074 (Check_Conventions): Capture condition to ignore a primitive operation
13075 (which is shared between the loop in Check_Conventions and the one in
13076 Check_Convention) in a new local function Skip_Check.
13077 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13078 confusion with Check_Conventions' own Prim_Op local variable.
13079 (Create_Extra_Formals): Test for a tagged result type rather than a
13080 controlling result when determining whether to add a BIP_Alloc_Form
13081 formal and a BIP_Final_List formal to the function.
13082 (Check_Conformance); For parameters that are anonymous access types,
13083 subtype conformance requires that the not null and the constant
13084 indicators must match
13085 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13086 to retrieve the appropriate type when processing a concurrent type
13087 declared within a generic. Minor comment reformatting. Change invocation
13088 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13090 (Analyze_Subprogram_Body): If the return type of a function is an
13091 anonymous access to the limited view of a class-wide type, and the
13092 non-limited view of the type is available, update the type of the
13093 function so that code can be generated.
13094 (Process_Formals): In case of access-subtype itype whose designated
13095 type is also an itype (situation that happens now with access to
13096 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13097 attribute to avoid backend problems.
13098 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13099 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13100 anonymous types' designated types are same before testing
13101 Subtypes_Statically_Match.
13102 (Create_Extra_Formals): Test for a named access parameter that is a
13103 controlling formal as an additional condition for adding an
13104 accessibility level formal. This can occur in the subp type created for
13105 dispatching calls in Expand_Dispatching_Call, and allows calling
13106 Create_Extra_Formals from that procedure rather than special-casing the
13107 extra formals there.
13108 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13109 when the function has a controlling result.
13110 (Check_Returns): Add much more knowledge of the optimization of local
13111 raise statements to gotos, to retain proper warnings in this case.
13112 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13113 nodes when looking for last statement.
13115 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13116 class-wide types visible through limited with clauses.
13117 (Add_One_Interp): If the operands are anonymous access types, the
13118 predefined operator on universal_access is immediately visibles
13119 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13120 other anonymous access types.
13121 (Disambiguate): Take into account CIL convention.
13122 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13124 2007-06-06 Robert Dewar <dewar@adacore.com>
13126 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13127 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13128 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13129 Fix lower bound of tables.
13132 * nlists.adb: Ditto.
13133 (Prev_Node, Next_Node): Change index type to Int so that it properly
13134 covers the range First_Node_Id - 1 up.
13136 2007-06-06 Javier Miranda <miranda@adacore.com>
13137 Ed Schonberg <schonberg@adacore.com>
13138 Bob Duff <duff@adacore.com>
13139 Hristian Kirtchev <kirtchev@adacore.com>
13141 * exp_aggr.ads, exp_aggr.adb:
13142 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13143 in extension aggregates.
13144 (Flatten): Other conditions being met, an aggregate is static if the
13145 low bound given by component associations is different from the low
13146 bound of the base index type.
13147 (Packed_Array_Aggregate_Handled): If the component type is itself a
13148 packed array or record, the front-end must expand into assignments.
13149 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13150 Init_Pr, instead of Ancestor_Is_Expression.
13151 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13152 coextension chain root, either generate a list controller or use the
13153 already existing one.
13154 (Static_Array_Aggregate): New procedure to construct a positional
13155 aggregate that can be handled by the backend, when all bounds and
13156 components are compile-time known constants.
13157 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13158 types covering interface types into assignments.
13159 (Replace_Type): move to Build_Record_Aggr_Code.
13160 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13161 interface type, convert to the definite type of the aggregate itself,
13162 so that needed components are visible.
13163 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13164 components and the context is an extended return statement do not
13165 create a transient block for it, to prevent premature finalization
13166 before the return is executed.
13167 (Gen_Assign): Do not generate a call to deep adjust routine if the
13168 component type is itself an array of controlled (sub)-components
13169 initialized with an inner aggregate.
13170 (Component_Check): New name for Static_Check. This name is now more
13171 appropriate, and documentation is added which was missing.
13172 (Component_Check): Add test for bit aligned component value
13173 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13174 Tagged_Comps, name is more appropriate given added function below.
13175 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13177 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13178 Javier Miranda <miranda@adacore.com>
13179 Robert Dewar <dewar@adacore.com>
13181 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13182 Terminated: Add unchecked type conversion from System.Address to
13183 System.Tasking.Task_Id when calling the predefined primitive
13185 Disable new Ada 05 accessibility check for JVM.NET targets, which
13186 cannot be implemented in a practical way.
13187 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13188 the sources always references the tag of the actual object. Therefore,
13189 if 'Tag is applied in the sources to class-wide interface objects we
13190 generate code that displaces "this" to reference the base of the object.
13191 (Expand_N_Attribute_Reference, case Size): Return specified size if
13192 known to front end.
13193 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13194 has code that displaces the pointer of the object to manage interface
13195 types. However this code must not be executed when the prefix is a
13196 subprogram. This bug caused the wrong expansion of the internally
13197 generated assignment that fills the dispatch table when the primitive
13198 is a function returning a class-wide interface type.
13199 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13200 Set_Attribute_Name for Name_Unaligned_Valid.
13202 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13203 Gary Dismukes <dismukes@adacore.com>
13205 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13206 If the initialization is the equivalent aggregate of the initialization
13207 procedure of the type, do not remove it.
13208 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13209 initialized to null from having their expression reset to empty and
13210 note this exception in the comment.

13214 Ed Schonberg <schonberg@adacore.com>
13215 Gary Dismukes <dismukes@adacore.com>
13217 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13218 Add "with" and "use" clauses for Sem_Attr.
13219 (Expand_Current_Value): Do not replace occurences of attribute
13220 references where the prefix must be a simple name.
13222 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13223 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13224 Attribute_Requires_Simple_Name_Prefix.
13225 (Name_Modifies_Prefix): Body of new function.
13226 (Requires_Simple_Name_Prefix): Body of new function.
13227 (Resolve_Attribute, case Access): Improve error message for case of
13228 mismatched conventions.
13229 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13231 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13232 constrained subtype for a nominal unconstrained type, use its base type
13233 to check for conformance with the context.
13234 (Resolve_Attribute): Remove test of the access type being associated
13235 with a return statement from condition for performing accessibility
13236 checks on access attributes, since this case is now captured by
13237 Is_Local_Anonymous_Access.
13238 (Analyze_Access_Attribute): Set Address_Taken on entity
13239 (Analyze_Attribute, case Address): Set Address_Taken on entity
13240 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13241 validating an access attribute whose prefix is a current instance.
13242 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13243 applied to dispatching operations, if freezing is required then we set
13244 the attribute Has_Delayed_Freeze in the prefix's entity.
13245 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13246 current scope if access of local subprogram taken
13247 (Analyze_Access_Attribute): Check legality of self-reference even if the
13248 expression comes from source, as when a single component association in
13249 an aggregate has a box association.
13250 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13251 the prefix if it is a protected operation and the attribute is
13252 Unrestricted_Access.
13253 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13254 reference to the base type of the context, to force a constraint check
13255 when the context is an access subtype with an explicit constraint.
13256 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13257 node is rewritten as an interface conversion. leave unanalyzed after
13258 resolution, to ensure that type checking against the context will take

13262 Javier Miranda <miranda@adacore.com>
13263 Robert Dewar <dewar@adacore.com>
13265 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13266 wrapper when the full view of the controlling type of an inherited
13267 function that dispatches on result implements interfaces.
13268 (Expand_N_Object_Declaration): In cases where the type of the
13269 declaration is anonymous access, create finalization list for it.
13270 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13271 if the object has no explicit initialization, to match description of
13272 functionality of pragam Persistent_BSS.
13273 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13274 new function to build static aggregates, to replace initialization call
13275 when static initialization is desired.
13276 (Freeze_Type): Generate a list controller for an access type whenever
13277 its designated type has controlled anonymous access discriminants.
13278 (Build_Equivalent_Aggregate): New procedure to compute a static
13279 aggregate to be used as default initialization for composite types,
13280 instead of a generating a call to the initialization procedure for the
13282 (Build_Initialization_Call): When available, replace a call to the
13283 initialization procedure with a copy of the equivalent static aggregate
13285 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13286 declarations for objects of a class-wide interface type, rather than
13287 just identifiers, to prevent visibility problems.
13288 (Expand_N_Object_Declaration): When expanding the declaration for an
13289 object of a class-wide interface type, preserve the homonym chain of
13290 the original entity before exchanging it with that of the generated
13291 renaming declaration.
13292 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13293 active, because there is no way to handle the exception.
13294 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13295 to do a minimum decoration of the Access_Disp_Table list.
13296 (Expand_Record_Controller): Avoid the addition of the controller between
13297 the component containing the tag of a secondary dispatch table and its
13298 adjacent component that stores the offset to the base of the object.
13299 This latter component is only generated when the parent type has
13300 discriminants ---documented in Add_Interface_Tag_Components).
13301 (Apply_Array_Size_Check): Removed, no longer needed.
13302 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13303 components, create a Master_Entity for it only if it contains tasks.
13304 (Build_Init_Procedure): Suppress the tag assignment compiling under
13306 (Freeze_Record_Type): Remove code associated with creation of dispatch
13308 (Init_Secondary_Tags): Update type of actuals when generating calls to
13309 Ada.Tags.Set_Offset_To_Top
13310 (Stream_Operation_OK): Disable use of streams compiling under no
13312 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13313 if Has_Init_Expression set.
13314 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13315 Register_Primitive, which provides the same functionality.
13316 (Requires_Init_Proc): Return false in case of interface types.
13317 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13319 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13320 is always associated with a predefined primitive because the internal
13321 entities associated with interface types are not predefined primitives.
13322 Therefore, the call to Is_Internal is replaced by a call to the
13323 function Is_Predefined_Dispatching_Operation.
13324 (Make_Eq_If): When generating the list of comparisons for the
13325 components of a given variant, omit the controller component that is
13326 present if the variant has controlled components.
13328 2007-06-06 Javier Miranda <miranda@adacore.com>
13329 Hristian Kirtchev <kirtchev@adacore.com>
13330 Bob Duff <duff@adacore.com>
13332 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13333 handle the creation of finalization lists and calls for nested
13334 coextensions when the root of the chains is part of a return statement.
13335 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13337 (Expand_Record_Equality): Skip components that are interface types.
13338 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13339 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13340 with Rewrite_Coextension. Change the condition for detecting coextension
13342 (Is_Local_Access_Discriminant): Removed.
13343 (Rewrite_Coextension): New routine which rewrites a static coextension
13344 as a temporary and uses its unrestricted access in the construction of
13346 (Complete_Coextension_Finalization): New routine. Generate finalization
13347 attachment calls to all delayed coextensions.
13348 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13349 the allocator is not a coextension itself and has delayed coextensions.
13350 If the current allocator is controlled, but also a coextension, delay
13351 the generation of the finalization attachment call.
13352 Rename local variable "Node" to "Nod" in order to avoid confusion with
13354 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13355 limited types that are not inherently limited. Such an allocator is
13356 illegal, but is generated by the expander for a return statement, to
13357 copy the result onto the secondary stack. This is the only case where a
13358 limited object can be copied. Generate code to displace the pointer
13359 to the object if the qualified expression is a class-wide interface
13360 object. Such displacement was missing and hence the copy of the object
13362 (Apply_Accessibility_Check): Handle allocated objects initialized in
13364 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13365 and Expand_Allocator_Expression. Allocating class-wide interface objects
13366 this routine displaces the pointer to the allocated object to reference
13367 the component referencing the corresponding secondary dispatch table.
13368 Expand_Allocator_Expression): Add missing support to allocate class-wide
13369 interface objects initialized with a qualified expression.
13370 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13371 function result type, and use the finalization list associated with the
13372 function scope in that case (such an anonymous type should not be
13373 treated like an access parameter's type).
13375 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13376 Gary Dismukes <dismukes@adacore.com>
13377 Javier Miranda <miranda@adacore.com>
13379 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13380 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13381 required exception handler.
13382 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13383 properly the case of a function whose return type is a limited
13384 class-wide interface type. Modify the code of the accessibility
13385 check to handle class-wide interface objects. In this case we need to
13386 displace "this" to reference the primary dispatch table to get access
13387 to the TSD of the object (to evaluate its accessibility level).
13388 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13389 rather than a controlling result as one of the conditions for
13390 generating tests of the implicit BIP_Alloc_Form formal. The
13391 initialization assignment is also handled according to whether the
13392 result is tagged instead of controlling.
13393 In the case where the init assignment is inserted in the "then" part of
13394 the allocation conditional, rewrite the target to be a dereference of
13395 the implicit BIP_Object_Access formal.
13396 If the returned value is unconstrained and created on the secondary
13397 stack, mark the enclosing block and function so that the secondary
13398 stack is not reclaimed on return.
13399 Treat returns from functions with controlling results similarly to
13400 returns from functions with unconstrained result subtypes.
13401 If the object returned is unconstrained, and an allocator must be
13402 created for it, analyze the allocator once the block for the extended
13403 return is installed, to ensure that finalizable components
13404 of the expression use the proper finalization list. Guard the call to
13405 Move_Final_List with a check that there is something to finalize.
13406 (Make_Tag_Ctrl_Assignment): Use "old" handling
13407 of controlled type assignment for virtual machines, since new code uses
13408 unsupported features (such as direct access to bytes in memory).
13410 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13411 Ed Schonberg <schonberg@adacore.com>
13413 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13414 accessibility actual, check for the case of an aliased object that has
13415 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13416 we fall into processing for the attribute rather than the name of the
13418 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13419 formal has its address taken in the body, create a temporary to capture
13420 value. If the return type is a limited interface, do not treat the
13421 return value as Controlled.
13422 (Is_In_Place_Function): If the return type is a limited interface,
13423 treat as returning in place. The actual returned object may not always
13424 be limited, but the caller has to assume that it is returned in place.
13425 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13426 context of an allocator, use the correct finalization chain (that is,
13427 the chain belonging to the access type, rather than the chain belonging
13428 to the current scope).
13429 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13430 result type rather than a controlling result as a precondition for
13431 adding an allocation form actual to a build-in-place call.
13432 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13433 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13434 primitive in the dispatch tables. This work is now done by Make_DT when
13435 the type is frozen.
13436 (Register_Predefined_DT_Entry): Removed.
13437 (Add_Return): If end label is not present, use sloc of last statement
13438 for generated return statement in procedure, for better gdb behavior

13445 the allocation form parameter if the result subtype is constrained,
13446 except when the function has a controlling result.
13447 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13448 rather than Is_Controlled and Has_Controlled_Component, since we want to
13449 include class-wide result types in this treatment. Also test for a
13450 controlling result, since that also requires passing a finalization
13452 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13453 even when the result subtype is constrained, to handle calls involving
13454 controlling results.
13455 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13456 is now called even when the result subtype is constrained, to handle
13457 calls involving controlling results.
13458 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13459 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13460 now performs the test).
13461 (Make_Build_In_Place_Call_In_Object_Declaration):
13462 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13463 constrained, to handle calls involving controlling results.
13464 (Add_Return): Accomodate rewritten pattern from local raise to goto
13465 transformation, so that we still recognize an transfer statement
13466 and do the right thing here in that case.
13467 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13468 and end of subprogram code.
13469 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13470 support for primitives that are functions (without formals) with a
13471 controlling result.

13473 type, it is not an actual for a formal derived type, and there is no
13474 operation to inherit from the formal.

13483 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13484 Raise_From_Controlled_Operation is available, use a call to that
13485 subprogram instead of a plain "raise Program_Error" node to raise
13486 Program_Error if an exception is propagated from an Adjust or Finalize
13488 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13489 appears in the optional statement list of a triggering alternative, the
13490 scope actions can be inserted directly there, and not in the list that
13491 includes the asynchronous select itself.
13493 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13494 Robert Dewar <dewar@adacore.com>

13521 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13522 functionality when the backend is generating code.
13523 Otherwise any serious error
13524 reported by the backend calling the frontend routine Error_Msg
13525 changes the Compilation_Mode to Check_Semantics, disables the
13526 functionality of this routine and causes the generation of
13527 spureous additional errors.
13529 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13530 debugging information now generated by the compiler for fat-pointer
13532 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

13544 stream attributes of the designated type of an RACW, as they are not
13545 dispatching primitive operations.

13565 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13566 deallocation of class-wide interface objects.
13567 (Expand_Dispatching_Constructor_Call): Take into account that if the
13568 result of the dispatching constructor is an interface type, the
13569 function returns a class-wide interface type; otherwise the returned
13570 object would be actual. The frontend previously accepted returning
13571 interface types because Expand_Interface_Actuals silently performed
13572 the management of the returned type "as if" it were a class-wide
13574 (Expand_Dispatching_Constructor_Call): Replace call to
13575 Make_DT_Access_Action by direct call to Make_Function_Call.

13598 renaming, either an attribute renaming or a renaming as body.
13599 (Check_Itype): If the designated type of an anonymous access component
13600 is a non-protected subprogram type, indicate that it is frozen, to
13601 prevent out-of-scope freeze node at some subsequent call.
13602 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13603 only if the subprogram is neither imported nor exported, as well as the

13609 Gary Dismukes <dismukes@adacore.com>
13611 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a

13633 to apply Import to an object renaming declaration.
13635 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13636 from a C++ class should be declared as limited and that it will be
13637 considererd limited.
13638 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13639 should be declared as limited and that it will be considererd limited.
13640 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas

13664 object of a limited type can be initialized with a call to a function
13665 that returns in place. If the limited type has unknown discriminants,
13666 and the underlying type is a constrained composite type, build an actual
13667 subtype from the function call, as is done for private types.
13668 (Side_Effect_Free): An expression that is the renaming of an object or
13669 whose prefix is the renaming of a object, is not side-effect free
13670 because it may be assigned through the renaming and its value must be
13671 captured in a temporary.
13672 (Has_Controlled_Coextensions): New routine.
13673 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13674 as is done for other limited types.

13724 Add new warning for renaming of function return objects
13726 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size

13731 * opt.ads: Add new warning for renaming of function return objects
13732 (Generating_Code): New boolean variable used to indicate that the

13746 Standard can be renamed.
13747 (Analyze_Object_Renaming): Add new warning for renaming of function
13749 Also reject attempt to rename function return object in Ada 83 mode.
13750 (Attribute_Renaming): In case of tagged types, add the body of the
13751 generated function to the freezing actions of the type.
13752 (Find_Type): A protected type is visible right after the reserved word
13753 "is" is encountered in its type declaration. Set the entity and type

13781 (Deallocate, Dereference): Send error messages to the proper stream
13782 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
13783 documented. Previous code would send it to the current output file
13784 defined in GNAT.IO, which might not be stdout
13785 (Is_Valid): Adjust comment to mention that a positive reply means that
13786 Header_Of may be used to retrieve the allocation header associated with
13787 the subprogram Storage address argument. Return False early if this

13806 Correct error message when invocation of the linker fails
13807 Add explicit size clause for the C imported variables
13808 Object_List_File_Supported and Using_GNU_Linker to emphasize that
13809 we expect char size.
13810 Read target parameters earlier, since this is needed to set
13811 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13814 2007-06-06 Vincent Celier <celier@adacore.com>
13817 Add 3 spaces before the default project directory when displaying
13818 the project search path.

14197 association, and the corresponding record component has a default
14198 expression, always copy the default expression, even when the

14375 occurs on an allocator node. Add processing and cleanup for static
14377 (Valid_Conversion): If the operand type is the limited view of a
14378 class-wide type, use the non-limited view is available to determine
14379 legality of operation.
14380 (Ambiguous_Character): move to spec, for use elsewhere.
14381 (Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
14382 (Resolve_Range): Diagnose properly an ambiguous range whose bounds are
14383 character literals.
14384 (Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
14385 Do_Division_Check flag explicitly.
14386 (Resolve_Actuals): If the actual is of a synchronized type, and the
14387 formal is of the corresponding record type, this is a call to a
14388 primitive operation of the type, that is declared outside of the type;
14389 the actual must be unchecked-converted to the type of the actual
14390 (Resolve_Call): Kill all current values for any subprogram call if
14391 flag Suppress_Value_Tracking_On_Call is set.

14393 or target of interface conversions come from a limited view.
14394 (Check_Infinite_Recursion): Ignore generated calls
14395 (Check_Allocator_Discrim_Accessibility): New procedure for checking
14396 that an expression that constrains an access discriminant in an
14397 allocator does not denote an object with a deeper level than the
14398 allocator's access type.
14399 (Resolve_Allocator): In the case of an allocator initialized by an
14400 aggregate of a discriminated type, check that associations for any
14401 access discriminants satisfy accessibility requirements by calling
14402 Check_Allocator_Discrim_Accessibility.

14407 (Resolve_Type_Conversion): Add missing support for conversion to
14409 (Resolve_Actuals): Introduce a transient scope around the call if an
14410 actual is a call to a function returning a limited type, because the

14424 both entities. This is required to statically build the dispatch table.
14425 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14426 of calling Set_All_DT_Position to re-evaluate the position of the
14427 entries in the dispatch table. Such reevaluation is not desired if

14498 (Rmsg_28): Fix description for E.4(18) check.
14499 (Raise_Current_Excep): Call Debug_Raise_Exception just before
14500 propagation starts, to let debuggers know about the event in a reliable
14502 Take the address of E and dereference to make sure it is homed on stack
14503 and prevent the stores from being deleted, necessary for proper

15296 (Resolve_Call): If the call returns an array, the context imposes the
15297 component type of the array, and the function has one non-defaulted
15298 parameter, rewrite the call as the indexing of a call with a single
15299 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15301 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15302 the master of the created object is the innermost enclosing statement.
15303 (Remove_Conversions): For a binary operator, check if type of second

15551 that use (a subtype of) the class-wide type of the enclosing type.
15552 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15553 Derived_Type for Prev formal on call to
15554 Check_Anonymous_Access_Components rather than Empty.
15555 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15556 a record extension in deciding whether to create a class-wide type,

15688 same scope level as the allocator's type. The check is guaranteed to
15689 succeed in that case, even when the expression originates from a
15690 parameter of the containing subprogram.
15691 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15692 under No_Dispatching_Calls restriction. During the semantic analysis
15693 we already notified such violation.
15694 (Tagged_Membership): Constant folding. There is no need to check
15695 the tag at run-time if the type of the right operand is non
15696 class-wide abstract.
15697 Replace call to Is_Ancestor by call to Is_Parent
15698 to support concurrent types with interface types.
15699 (Expand_N_Allocator): Add an assertion associated with the generation
15701 (Expand_N_Slice): Do not enable range check to nodes associated
15702 with the frontend expansion of the dispatch table.

15704 Expand_N_Allocator.
15705 (Tagged_Membership): Replace generation of call to the run-time
15706 subprogram CW_Membership by call to Build_CW_Membership.
15707 (Expand_Allocator_Expression): Replace generation of call to the
15708 run-time subprogram Get_Access_Level by call to Build_Get_Access_Level.
15710 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15711 initialize most the TSD components by means of an aggregate.
15712 Modify the declaration of the object containing the TSD
15713 because we now expand code that has a higher level of abstraction.
15714 The TSD has a discriminant containing the Inheritance Depth Level,
15715 value that is used in the membership test but also to fix the size
15716 of the table of ancestors.
15717 (Expand_Interface_Conversion): Insert function body at the closest place
15718 to the conversion expression, to prevent access-before-elaboration
15719 errors in the backend.
15720 Code improved to reduce the size of the dispatch table if
15721 compiling under restriction No_Dispatching_Calls plus code cleanup.
15722 Code reorganization plus removal of calls to Set_Num_Prim_Ops
15723 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
15724 (Expand_Dispatching_Call): Minor code reorganization plus addition of
15725 code to return immediately if compiling under No_Dispatching_Calls
15727 (Set_All_DT_Position): Remove code associated with the old CPP pragmas.
15728 CPP_Virtual and CPP_Vtable are no longer supported.
15729 (Expand_Interface_Conversion): Add missing support for interface type
15731 (Expand_Interface_Actuals): Replace calls to Is_Ancestor by calls to
15732 Is_Parent to support concurrent types with interfaces.

15735 (Set_All_DT_Position): Modified to support concurrent record types.
15736 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
15737 with Get_External_Tag, Inherit_TSD, Set_External_Tag.
15738 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entry associated
15739 with CW_Membership.
15740 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
15741 with Get_Access_Level, Get_Predefined_Prim_Op_Address,
15742 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,
15743 Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
15744 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15745 (Expand_Dispatching_Call): Replace generation of call to the run-time
15746 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15747 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15749 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15750 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15751 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15752 Build_Set_Prim_Op_Address.
15753 (Get_Remotely_Callable): Subprogram removed.
15754 (Init_Predefined_Interface_Primitives): Replace generation of call to
15755 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15758 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15759 First (Parameter_Associations ()) with the call to First_Actual that
15760 returns an actual parameter expression for both named and positional
15763 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15764 check violation of restriction No_Dispatching_Calls.
15765 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15766 controlling argument.
15768 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
15769 First/Next_Component_Or_Discriminant
15770 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15771 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15772 specify Any_Limited_Interface, and this functionality is already
15773 provided by the function Has_Abstract_Interfaces.
15774 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15775 support concurrent types implementing interfaces.
15776 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15777 specify kind Any_Limited_Interface, and this functionality is already
15778 provided by the function Has_Abstract_Interfaces.
15779 (Remove_Side_Effects): replace Controlled_Type by
15780 CW_Or_Controlled_Type whenever the issue is related to
15781 using or not the secondary stack.
15783 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15784 P_Interface_Type_Definition to fulfill the new interface (the formal
15785 Is_Synchronized is no longer required).
15787 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
15788 Update dependencies.
15790 * exp_atag.ads, exp_atag.adb: New file
15792 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15793 Bob Duff <duff@adacore.com>
15794 Cyrille Comar <comar@adacore.com>
15796 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15797 anonymous, use finalization list of enclosing dynamic scope.
15798 (Expand_N_Package_Declaration): For a library package declaration
15799 without a corresponding body, generate RACW subprogram bodies in the
15800 spec (just as we do for the task activation call).
15801 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15802 Is_Abstract_Type. Make sure these are called only when appropriate.
15803 Remove all code for DSP option
15804 (CW_Or_Controlled_Type): new subprogram.
15806 2007-04-06 Eric Botcazou <botcazou@adacore.com>
15807 Ed Schonberg <schonberg@adacore.com>
15808 Gary Dismukes <dismukes@adacore.com>
15810 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15811 parameter. If it is set to true, return a result capped according to
15812 the global upper bound for the index of an entry family.
15813 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15814 (Build_Find_Body_Index): Adjust for above change.
15815 (Entry_Index_Expression): Likewise.
15816 (Is_Potentially_Large_Family): New function extracted from...
15817 (Collect_Entry_Families): ...here. Call it to detect whether the family
15818 is potentially large.
15819 (Build_Entry_Count_Expression): If the family is potentially large, call
15820 Family_Size with 'Cap' set to true.
15821 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15822 a protected version of an operation declared in the private part of
15823 a protected object, because they may be invoked through a callback.
15824 (Set_Privals): If the type of a private component is an anonymous access
15825 type, do not create a new itype for each protected body.
15826 If the body of a protected operation creates
15827 controlled types (including allocators for class-widetypes), the
15828 body of the corresponding protected subprogram must include a
15830 (Build_Activation_Chain_Entity): Build the chain entity for extended
15832 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15833 to determine whether operation overrides an inherited primitive.
15834 (Build_Wrapper_Spec): Add code to examine the parents while looking
15835 for a possible overriding candidate.
15836 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15837 hold an actual parameter value since its initialization is separated
15838 from the the declaration. Prevents errors on null-excluding access
15841 2007-04-06 Thomas Quinot <quinot@adacore.com>
15842 Pablo Oliveira <oliveira@adacore.com>
15844 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15845 Do an Unchecked_Conversion to handle the passage from the Underlying
15846 Type to the Base Type when calling Build_To_Any_Call and
15847 Build_From_Any_Call.
15848 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15849 E_Constant, depending upon Variable formal.
15850 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15851 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15852 parameter that requires an extra constrained parameter, declare
15853 temporary for actual as a variable, not a constant.
15854 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15855 the unit being compiled is the one that contains the stub type.
15856 Change primitive operation name for the RACW associated with a RAS
15857 from Call to _Call so it cannot clash with any legal identifier.
15858 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15860 (Append_RACW_Bodies): New subprogram.
15861 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15862 Add_Receiving_Stubs_To_Declarations functions.
15863 When expanding a package body, this list correspond to the
15864 statements in the HSS at the end of the pacakge.
15865 When expanding a package spec, this list correspond to the
15867 (Add_Receiving_Stubs_To_Declarations): Append the function
15868 registering the receiving stubs at the end of the 'Stmts' list.
15869 (RCI_Package_Locator): Pass the new Version generic formal when
15870 instantiating a RCI_Locator package.
15871 (Build_From_Any_Function): To compute the High bound for an
15872 unconstrained array actual, we add the Low bound with the length.
15873 Thus we must convert the low bound and the length to an appropriate
15874 type before doing the sum.
15875 (Build_Subprogram_Receiving_Stubs, PolyORB):
15876 * Retrieve the extra formals parameters at the
15877 end of the parameter stream.
15878 * Use Move_Any_Value to write back out parameters
15879 after executing the request as it is more efficient
15880 than Copy_Any_Value.
15881 * Build the any containing Extra Formals with the
15882 appropriate typecode.
15883 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15884 empty Component_List.
15885 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15886 the tree the declaration for an object that serves as actual parameter
15887 in server-side stubs.
15888 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15889 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15890 Use Build_Actual_Object_Declaration to prepare the actuals.

15892 Extra Constrained Parameters.
15893 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15894 Extra Constrained parameters.

15897 function with the first not implicit parent type.
15898 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15899 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15900 typecode from the Etype. Therefore we retrieve the correct typecode
15901 with a call to Get_Any_Type.
15902 (Copy_Specification): Do controlling formal type substitution based on
15903 Is_Controlling_Formal flag, instead of caller-provided object type.
15904 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15905 a RACW primitive operation, we might get a subprogram declaration for an
15906 ancestor of the RACW designated type (not for the designated type
15907 itself), in the case where this operation is inherited. In this case we
15908 have no easy means of determining the original tagged type for which
15909 the primitive was declared, so instead we now rely on
15910 Copy_Specification to use the Is_Controlling_Formal flag to determine
15911 which formals require type substitution.

15914 Ed Schonberg <schonberg@adacore.com>
15916 * exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
15917 GNAT.Current_Exception are not allowed if pragma Restrictions
15918 (No_Exception_Propagation) is set and in any case make the associated
15919 handler unsuitable as a target for a local raise statement.
15920 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15921 run-time subprogram CW_Membership by call to Build_CW_Membership.
15922 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15923 by a function call, a temporary must be created before expanding the
15924 Constructor_Call itself, to prevent out-of-order elaboration in the
15925 back-end when stack checking is enabled..
15927 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15929 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15930 result are the bounds of the left operand, not the right.
15932 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15935 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use
15936 discriminant defaults.

15941 Bob Duff <duff@adacore.com>
15943 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
15944 an association with a box as providing a value even though the
15945 initialization procedure for the type is not available.

15947 box corresponds to a component of the type.
15948 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15949 Is_Abstract_Subprogram and Is_Abstract_Type.
15951 * exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
15954 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
15955 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
15956 called only when appropriate.

15960 * g-alleve.ads (Low Level Vector type definitions): Map each to the
15961 associated vector view instead of all to the unsigned char view.

15964 offering facilities for all the Vector/View conversion routines
15965 implemented by this unit.

16008 switches, and get the single attribute Switches from the stack package
16009 in a project file when calling gnatstack. Parse the -U flag for
16010 processing files belonging to all projects in the project tree.
16011 Remove all processing for command Setup
16013 * prj-attr.adb: Add new package Stack with single attribute Switches

16046 * i-cstrea.ads: (fopen): Add encoding parameter.
16048 Change reference from a-sysdep.c to sysdep.c in comment.
16049 Update copyright notice.
16050 This set of patch add support for the encoding form parameter.
16052 * mingw32.h (S2WSU): New macro to convert from a string to a
16053 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16054 standard 8bits encoding.
16055 (WS2SU): As above but converting from wide-sring to string.
16056 This is needed as it is necessary to have access to both versions in the
16057 runtime for the form parameter encoding support.
16058 This set of patch add support for the encoding form parameter.
16059 (S2WS): Improve implementation to handle cases where the filename is not
16060 UTF-8 encoded. In this case we default to using the current code page
16061 for the conversion.
16063 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16064 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16070 encoding. This is needed for the Reset routine (freopen low level-call).
16072 * s-fileio.adb (Open): Decode encoding form parameter and set the
16073 corresponding encoding value into AFCB structure.
16074 (Reset): Pass the encoding value to freopen.
16075 (Close): Move the call to Lock_Task to the beginning of the procedure.

16108 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16109 __gnat_adjust_context_for_raise.
16110 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16111 implementation of floating point operations as native x86 targets.
16112 So the FPU should be initialized in the same way using finit. Fix
16113 floating point operations accuracy issues.
16114 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16115 member in struct sigaction, so as to avoid warning for incompatible

16133 * lib-xref.ads, lib-xref.adb:
16134 Modify the loop that collects type references, to include interface
16135 types that the type implements. List each of these interfaces when
16136 building the entry for the type.
16137 (Generate_Definition): Initialize component Def and Typ of new entry
16138 in table Xrefs, to avoid to have these components unitialized.
16139 (Output_References): Split Is_Abstract flag into
16140 Is_Abstract_Subprogram and Is_Abstract_Type.
16141 (Generate_Reference): Add barrier to do not generate the warning
16142 associated with Ada 2005 entities with entities generated by the

16182 2007-04-06 Robert Dewar <dewar@adacore.com>
16184 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16185 it no longer destroys the contents of Name_Buffer or Name_Len and
16186 non-standard and invalid names are handled better.
16187 (Get_Decoded_Name_String): Improve performance by using
16188 Name_Has_No_Encodings flag in the name table.
16189 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16190 Used for debugging printouts.

16193 Javier Miranda <miranda@adacore.com>
16194 Bob Duff <duff@adacore.com>
16196 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16197 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16198 there is no need to generate always a record_definition_node in case
16199 of synchronized interface types.
16200 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16201 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16202 illegal in Ada 95, in cases where it is legal. Change the warnings to
16203 errors in other cases. Don't give the error unless the "not null"
16204 parses properly. Correct the source position at which the error occurs.
16205 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16206 P_Null_Exclusion, to suppress "not null" warnings.

16258 Entry for pragma Unreferenced_Objects
16260 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16261 switches, without repetition of "eD". Make sure that last character of
16262 -gnatep= switch is not taken as -gnat switch character.
16263 Complete rewrite of circuit for handling saving compilation options
16264 Occasioned by need to support dot switchs for -gnatw, but cleans up

16282 the default project path, initially done during elaboration of the
16284 If the prefix returned by Sdefault is null, get the prefix from a call
16285 to Executable_Prefix_Path.
16286 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16289 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16290 canonical directory name to open the directory from which files are
16292 (Record_Other_Sources): Idem.
16293 (Locate_Directory): Add the possibility to create automatically missing
16294 directories when Setup_Projects is True.
16295 Call Locate_Directory so that the directory will be created when
16296 Setup_Projects is True, for object dir, library dir, library ALI dir,
16297 library source copy dir and exec dir.
16299 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16302 2007-04-06 Robert Dewar <dewar@adacore.com>

16317 Next_Component_Or_Discriminant.
16319 * style.ads, styleg-c.adb, styleg-c.ads (Check_Array_Attribute_Index):
16322 * stylesw.ads, stylesw.adb: Recognize new -gnatyA style switch

16337 full word is no longer compared twice.
16339 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16341 * sem_ch10.adb (Install_Limited_Context_Clauses.
16342 Expand_Limited_With_Clause): Use a new copy of selector name in the
16343 call to Make_With_Clause. This fixes the tree structure for ASIS
16344 purposes. Nothing is changed in the compiler behaviour.
16345 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16346 a package renaming.
16347 (Install_Limited_With_Clauses): Do not install non-limited view when it
16348 is still incomplete.
16350 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16351 Gary Dismukes <dismukes@adacore.com>
16353 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16354 when capturing size information, instead of base type, which for a
16355 formal array type will be the unconstrained type.
16356 (Analyze_Formal_Object_Declaration): Add check for illegal default
16357 expressions for a formal in object of a limited type.
16358 (Instantiate_Object): Ditto.
16359 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16360 because they were defaulted in the formal package and no check applies
16362 (Check_Formal_Package_Instance): Extend conformance check to other
16363 discrete types beyond Integer.
16364 (Process_Default): Copy directly the unmatched formal. A generic copy
16365 has already been performed in Analyze_Formal_Package.
16366 (Analyze_Associations): If a formal subprogram has no match, check for
16367 partial parametrization before looking for a default, to prevent
16369 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16370 not set the instantiation environment before analyzing the actuals.
16371 Fixes regression on 8515-003 with implementation of AI-133.
16372 Set_Instance_Env checks whether the generic unit is a predefined
16373 unit, in which case the instance must be analyzed with the latest Ada
16374 mode. This setting must take place after analysis of the actuals,
16375 because the actuals must be analyzed and frozen in the Ada mode extant
16376 outside of the current instantiation.
16377 (Save_Env, Restore_Env): Preserve and restore the configuration
16378 parameters so that predefined units can be compiled in the proper Ada
16380 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16381 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16382 and Is_Abstract_Type.
16383 (Analyze_Formal_Package): For better error recovery, Add exception
16384 handler to catch Instantion_Error, which can be raised in
16385 Analyze_Associations
16387 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16388 Bob Duff <duff@adacore.com>
16389 Gary Dismukes <dismukes@adacore.com>
16391 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16392 prefix type is a discriminated subtype of the type of the formal.
16393 (Analyze_Allocator): Collect all coextensions regardless of the context.
16394 Whether they can be allocated statically is determined in exp_ch4.
16395 (Analyze_Selected_Component): If the prefix is a limited view and the
16396 non-limited view is available, use the non-limited one.
16397 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16398 therefore illegal), suggest a qualified expression rather than a type
16399 conversion, because a type conversion would be illegal in this context.
16400 (Anayze_Allocator): Trace recursively all nested allocators so that all
16401 coextensions are on the corresponding list for the root. Do no mark
16402 coextensions if the root allocator is within a declaration for a stack-
16403 allocated object, because the access discriminants will be allocated on
16405 (Analyze_Call): Remove restriction on calls to limited functions for the
16406 cases of generic actuals for formal objects, defaults for formal objects
16407 and defaults for record components.
16408 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16409 element list. Their expansion is delayed until the enclosing allocator
16410 is processed and its finalization list constructed.
16411 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16412 for an operation with the given name among the primitive operations of
16413 the corresponding record type.
16414 (Analyze_Selected_Component): If the prefix is a task type that
16415 implements an interface, and there is no entry with the given name,
16416 check whether there is another primitive operation (e.g. a function)
16418 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16419 properly the indexing of a function call written in prefix form, where
16420 the function returns an array type, and all parameters of the function
16421 except the first have defaults.
16422 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16423 the original operands, rather than relocating them, for efficiency and
16424 to work properly when an operand is overloaded.
16425 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16426 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16427 (Analyze_Selected_Component): If the prefix is a private extension, only
16428 scan the visible components, not those of the full view.
16429 (Try_Primitive_Operation): If the operation is a procedure, collect all
16430 possible interpretations, as for a function, because in the presence of
16431 classwide parameters several primitive operations of the type can match
16432 the given arguments.
16434 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16435 Robert Dewar <dewar@adacore.com>
16437 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16438 tag-indeterminate call to an abstract function, when the left-hand side
16440 (Analyze_Loop_Statement): Improve detection of infinite loops
16442 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16443 Thomas Quinot <quinot@adacore.com>
16445 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16446 out of Analyze_Package_Declaration, because processing must be applied
16447 to package bodies as well, for deferred constants completed by pragmas.
16448 (Analyze_Package_Declaration): When the package declaration being
16449 analyzed does not require an explicit body, call Check_Completion.
16450 (May_Need_Implicit_Body): An implicit body is required when a package
16451 spec contains the declaration of a remote access-to-classwide type.
16452 (Analyze_Package_Body): If the package contains RACWs, append the
16453 pending subprogram bodies generated by exp_dist at the end of the body.
16454 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16455 Is_Abstract_Subprogram and Is_Abstract_Type.
16456 (Preserve_Full_Attributes): The full entity list is not an attribute
16457 that must be preserved from full to partial view.
16459 * sem_dist.adb (Add_RAS_Dereference_TSS):
16460 Change primitive name to _Call so it cannot clash with any legal
16461 identifier, and be special-cased in Check_Completion.
16462 Mark the full view of the designated type for the RACW associated with
16463 a RAS as Comes_From_Source to get proper view switching when installing
16464 private declarations.
16465 Provite a placeholder nested package body along with the nested spec
16466 to have a place for Append_RACW_Bodies to generate the calling stubs
16467 and stream attributes.
16469 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16470 Robert Dewar <dewar@adacore.com>
16472 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16473 that is a limited view, check the non-limited view if available.
16474 (Undefined): Refine error message for missing with of Text_IO
16475 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16476 to distinguish real missing with cases.
16477 Fix format of all missing with messages
16478 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16479 renaming as body when renamed entity is abstract.
16481 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16482 Javier Miranda <miranda@adacore.com>
16484 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16485 predicate recursive, to handle complex expressions on literals whose
16486 spurious ambiguity comes from the abstract interpretation of some
16488 (Interface_Present_In_Ancestor): Add support to concurrent record
16490 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16491 Is_Abstract_Subprogram and Is_Abstract_Type.
16493 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16494 Javier Miranda <miranda@adacore.com>
16496 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16497 dereference of a local object R created as a reference to another
16498 object O, use the access level of O.
16499 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16500 rather than local Same_Formal_Type, to check whether protected operation
16501 overrides an inherited one.
16502 (Same_Formal_Type): New predicate, used when matching signatures of
16503 overriding synchronized operations, to handle the case when a formal
16504 has a type that is a generic actual.
16505 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16506 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16507 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16508 syntactic ambiguities involving indexing of function calls that return
16510 (Abstract_Interface_List): New subprogram that returns the list of
16511 abstract interfaces associated with a concurrent type or a
16512 concurrent record type.
16513 (Interface_Present_In_Parent): New subprogram used to check if a
16514 given type or some of its parents implement a given interface.
16515 (Collect_Abstract_Interfaces): Add support for concurrent types
16516 with interface types.
16517 (Has_Abstract_Interfaces): Add support for concurrent types with
16519 (Is_Parent): New subprogram that determines whether E1 is a parent
16520 of E2. For a concurrent type its parent is the first element of its
16521 list of interface types; for other types this function provides the
16522 same result than Is_Ancestor.
16523 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16524 (Collect_Synchronized_Interfaces): Removed because the subprogram
16525 Collect_Abstract_Interfaces provides this functionality.
16526 (Collect_Abstract_Interfaces): Minor update to give support to
16527 concurrent types and thus avoid undesired code duplication.
16528 (Get_Subprogram_Entity): Handle entry calls.
16529 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16531 (Enter_Name): Do not give -gnatwh hiding warning for record component
16532 entities, they never result in hiding.

16535 Robert Dewar <dewar@adacore.com>
16537 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
16538 to chain nested components that are allocators for access discriminants
16539 of the enclosing object.
16540 Add N_Push and N_Pop nodes
16541 New field Exception_Label added
16542 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16543 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
16544 (Is_Coextension): New flag for allocators, to mark allocators that
16545 correspond to access discriminants of dynamically allocated objects.
16546 (N_Block_Statement): Document the fact that the corresponding entity
16547 can be an E_Return_Statement.
16548 (Is_Coextension): New flag for allocators.
16549 Remove all code for DSP option
16551 * sprint.ads, sprint.adb: Display basic information for class_wide
16552 subtypes. Add handling of N_Push and N_Pop nodes
16554 2007-04-06 Arnaud Charlet <charlet@adacore.com>
16556 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16557 before propagating exception.
16559 2007-04-06 Olivier Hainque <hainque@adacore.com>
16561 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16562 an address always within the call instruction from a return address.
16564 2007-04-06 Olivier Hainque <hainque@adacore.com>
16565 Eric Botcazou <botcazou@adacore.com>
16567 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16568 expression with a COMPOUND_EXPR including the call instead of emitting
16569 the call directly here.
16570 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16571 high bound is constant and the slice is empty. Tidy.
16572 (tree_transform, case N_Op_Not): Handle properly the case where the
16573 operation applies to a private type whose full view is a modular type.
16574 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16575 Address_Clause, use the associated Expression as the GNAT tree
16576 representing the choice value to ensure the corresponding GCC tree is
16577 of the proper kind.
16578 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16579 instead of just the operands, as the base GCC stabilize_reference does.
16580 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16581 requested; otherwise fail.
16582 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16584 2007-04-06 Thomas Quinot <quinot@adacore.com>
16586 * uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
16587 implementation of UI_Div.

16862 anonymous access types.
16863 (Valid_Conversion): For a conversion to a numeric type occurring in an

17570 the parent part is a build-in-place function call, generate assignments.
17571 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17572 are build-in-place function calls.
17573 (Replace_Self_Reference): New subsidiary of
17574 Make_OK_Assignment_Statement, to replace an access attribute that is a
17575 self-reference into an access to the appropriate component of the
17576 target object. Generalizes previous mechanism to handle self-references
17577 nested at any level.
17578 (Is_Self_Referential_Init): Remove, not needed.
17579 (Is_Self_Referential_Init): New predicate to simplify handling of self
17580 referential components in record aggregates.

17582 check for presence of entity before checking for self-reference.
17583 (Has_Default_Init_Comps): Return True if a component association is a
17584 self-reference to the enclosing type, which can only come from a
17585 default initialization.
17586 (Make_OK_Assignment_Statement): If the expression is of the form
17587 Typ'Acc, where Acc is an access attribute, the expression comes from a
17588 default initialized self-referential component.
17589 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17590 that has been derived from several abstract interfaces we must also
17591 initialize the tags of the secondary dispatch tables.

17596 Robert Dewar <dewar@adacore.com>
17599 (Expand_Access_To_Protected_Op): If the context indicates that an access
17600 to a local operation may be transfered outside of the object, create an
17601 access to the wrapper operation that must be used in an external call.
17602 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17603 target, pass the Valid attribute applied to a floating-point prefix on
17604 to the back end without expansion.
17605 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17606 the allocated storage when it is specified by a per-object expression.
17607 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17608 Nothing to do here, the attribute has been rewritten during semantic

17617 into a fat pointer.
17618 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17619 subcomponent's enclosing variable is aliased with a constrained subtype.
17620 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17621 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17622 an aliased prefix must be known to be constrained in order to use True
17623 for the attribute value, and now it's possible for some aliased views
17624 to be unconstrained.
17626 2006-10-31 Robert Dewar <dewar@adacore.com>
17628 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17629 (Expand_Entity_Reference): Correct error of not handling subprogram
17630 formals in current_value processing.
17632 2006-10-31 Javier Miranda <miranda@adacore.com>

17637 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17638 register in the final list objects containing class-wide interfaces;
17639 otherwise we incorrectly register the tag of the interface in the final
17641 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17642 generate the wrapper if the parent primitive is abstract. This is
17643 required to report the correct error message.
17644 (Expand_N_Subtype_Indication): Do validity checks on range
17645 (Clean_Task_Names): If an initialization procedure includes a call to
17646 initialize a task (sub)component, indicate that the procedure will use
17647 the secondary stack.
17648 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17649 compatibility for interfacing with CPP by default.
17650 (Expand_N_Object_Declaration): Only build an Adjust call when the
17651 object's type is a nonlimited controlled type.
17652 * exp_ch3.adb: Add with and use of Exp_Ch6.
17653 (Expand_N_Object_Declaration): Check for object initialization that is a
17654 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17655 Object_Declaration to the call.
17656 (Freeze_Type): When the designated type of an RACW was not frozen at the
17657 point where the RACW was declared, validate the primitive operations
17658 with respect to E.2.2(14) when it finally is frozen.
17659 (Build_Initialization_Call,Expand_Record_Controller): Rename
17660 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17661 return-by-reference has no meaning in Ada 2005.
17662 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17663 to register tag of the immediate ancestor interfaces in the
17664 run-time structure.

17666 initialization of extension aggregates with abstract interfaces.
17667 (Build_Master_Renaming): Make public, for use by function declarations
17668 whose return type is an anonymous access type.
17669 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17670 Insert_List_Before_And_Analyze after the generation of the specs
17671 associated with null procedures.
17672 (Expand_Tagged_Root): Update documentation in its specification.
17673 (Init_Secondary_Tags): Update documentation.
17674 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17675 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17676 then generate code to inherit the contents of the dispatch table
17677 directly from the ancestor.
17678 (Expand_Record_Controller): Insert controller component after tags of
17679 implemented interfaces.
17680 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17681 create null procedure overridings when null procedures are inherited
17683 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17684 declarations for overriding null primitives inherited from interfaces.
17685 (Is_Null_Interface_Procedure): New function in
17686 Make_Null_Procedure_Specs.
17687 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17688 immediate ancestor of a tagged type is an abstract interface type we
17689 must generate the specification of the predefined primitives associated
17690 with controlled types (because the dispatch table of the ancestor is
17691 null and hence these entries cannot be inherited). This is required to
17692 elaborate well the dispatch table.

17700 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17702 (Expand_N_In): Do validity checks on range
17703 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17704 (Expand_N_Allocator): For "new T", if the object is constrained by
17705 discriminant defaults, allocate the right amount of memory, rather than
17706 the maximum for type T.
17707 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17708 when the allocator is initialized by a build-in-place call, since the
17709 allocator is already rewritten as a reference to the function result,
17710 and this prevents an unwanted duplication of the function call.
17711 Add with and use of Exp_Ch6.
17712 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17713 is a call to build-in-place function and apply
17714 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17715 untagged designated types).
17716 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17717 optimization if source or target is biased.
17718 (Expand_N_Allocator): Add comments for case of an allocator within a
17719 function that returns an anonymous access type designating tasks.
17720 (Expand_N_Allocator): apply discriminant checks for access
17721 discriminants of anonymous access types (AI-402, AI-416)

17730 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17731 (Expand_N_Assignment_Statement): Call
17732 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17733 build-in-place function call. Currently, this can happen only for
17734 assignments that come from aggregates.
17735 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17736 in order to alleviate the upward compatibility introduced by AI-318.
17737 (Expand_N_Extended_Return_Statement): Add support for handling the
17738 return object as a build-in-place result.
17739 (Expand_Non_Function_Return): Implement simple return statements nested
17740 within an extended return.
17741 (Enable_New_Return_Processing): Turn on the new processing of return
17743 (Expand_Non_Function_Return): For a return within an extended return,
17744 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17745 (Expand_N_Extended_Return_Statement): Implement AI-318
17746 (Expand_Simple_Function_Return): Ditto.
17747 (Expand_N_If_Statement): Handle new -gnatwt warning

17749 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17750 a protected object.
17751 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17752 validity checking of assignments to elementary record components.
17753 (Expand_N_Return_Statement): return Class Wide types on the secondary
17754 stack independantly of their controlled status since with HIE runtimes,
17755 class wide types are not potentially controlled anymore.
17757 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17760 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17761 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17762 it expects a block, procedure, or task. The return statement will get
17763 turned into a block, and Expand_Cleanup_Actions will happen then.
17765 2006-10-31 Robert Dewar <dewar@adacore.com>
17766 Ed Schonberg <schonberg@adacore.com>
17767 Bob Duff <duff@adacore.com>
17768 Gary Dismukes <dismukes@adacore.com>
17770 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17772 (Expand_Inlined_Call): Tagged types are by-reference types, and
17773 therefore should be replaced by a renaming declaration in the expanded
17774 body, as is done for limited types.
17775 (Expand_Call): If this is a call to a function with dispatching access
17776 result, propagate tag from context.
17777 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17779 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17780 build-in-place when the right-hand side of an assignment is a
17781 build-in-place function call.
17782 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17783 of the explicit dereference of the allocator to the result subtype of
17784 the build-in-place function. This is needed to satisfy type checking
17785 in cases where the caller's return object is created by an allocator for
17786 a class-wide access type and the type named in the allocator is a
17788 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17789 conversion of the reference to the declared object to the result subtype
17790 of the build-in-place function. This is needed to satisfy type checking
17791 in cases where the declared object has a class-wide type. Also, in the
17792 class-wide case, change the type of the object entity to the specific
17793 result subtype of the function, to avoid passing a class-wide object
17794 without explicit initialization to the back end.
17795 (Register_Interface_DT_Entry): Moved outside the body of
17796 Freeze_Subprogram because this routine is now public; it is called from
17797 Check_Dispatching_Overriding to handle late overriding of abstract
17798 interface primitives.
17799 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17800 adding an implicit access actual on a call to a build-in-place function.
17801 (Expand_Actuals): Test for an actual parameter that is a call to a
17802 build-in-place function and apply
17803 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17804 (Is_Build_In_Place_Function): New function to determine whether an
17805 entity is a function whose calls should be handled as build-in-place.
17806 (Is_Build_In_Place_Function_Call): New function to determine whether an
17807 expression is a function call that should handled as build-in-place.
17808 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17809 calls to build-in-place functions as the initialization of an allocator.
17810 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17811 handling calls to build-in-place functions in contexts that do not
17812 involve init of a separate object (for example, actuals of subprogram
17814 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17815 handling calls to build-in-place functions as the initialization of an
17816 object declaration.

17818 instantiation of Traverse_Body to avoid unreferenced warning.
17819 (Check_Overriding_Inherited_Interfaces): Removed.
17820 (Register_Interface_DT_Entry): Code cleanup.
17821 (Register_Predefined_DT_Entry): Code cleanup.
17822 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17823 inlined statements if within a transient scope.
17824 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17825 formal parameters with occurrences of actuals in inlined body, establish
17826 visibility on the proper view of the actual's subtype for the body's
17828 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17829 compatibility mode and we have an imported CPP subprogram because
17830 for now we assume that imported CPP primitives correspond with
17831 objects whose constructor is in the CPP side (and therefore we
17832 don't need to generate code to register them in the dispatch table).
17833 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17834 aligned selected component.
17835 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17836 the actual of an in-mode parameter is a type conversion.
17837 (Expand_Actuals): If the call does not come from source and the actual
17838 is potentially misaligned, let gigi handle it rather than rejecting the
17839 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17840 Class Wide types as returning by reference independantly of their
17841 controlled status since with HIE runtimes class wide types are not
17842 potentially controlled anymore.
17844 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17846 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17847 references that are private components of the protected object.
17848 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17849 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17850 instantiation to deal with warnings.

17857 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17858 initialization of Homonym_Len.
17859 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17860 names from fully qualified name. Fixes problem of duplicate
17861 external names differing only in the presence of such a block name.
17863 2006-10-31 Thomas Quinot <quinot@adacore.com>
17864 Pablo Oliveira <oliveira@adacore.com>
17866 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17867 subprogram Ids, even if they are not yet assigned.
17868 (Build_Subprogram_Id): It is now this function that will take care of
17869 calling Assign_Subprogram_Ids if necessary.
17870 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17871 should be done only once they are assigned.
17872 (Build_From_Any_Function, case of tagged types): Add missing call to
17874 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17875 type for an RACW type.
17876 (Add_RACW_Features): When processing an RACW declaration for which the
17877 designated type is already frozen, enforce E.2.2(14) rules immediately.
17878 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17879 special reordering of controlling formals.
17881 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17882 associated stub type for an RACW type.
17884 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17886 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17887 fixed-point operations in an integer context, i.e. as operands of a
17888 conversion to an integer type, indicate that result must be rounded.
17890 2006-10-31 Robert Dewar <dewar@adacore.com>
17892 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17893 cases, pass the encoding method, since it is now required by the run
17896 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17897 assumption that Str'First = 1.
17898 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17899 it on to the Value_Wide_Wide_Character call.
17900 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17901 properly handles a string of the form quote-encoded_wide_char-quote.
17903 * s-wchcnv.adb: Minor reformatting
17905 2006-10-31 Javier Miranda <miranda@adacore.com>

17913 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17914 Machine_Attribute pragma internally to implement the user pragma.
17915 Add processing for pragma Interface so that it is now completely
17916 equivalent to pragma Import.
17918 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17919 so that it can be applied to all entities, including record components
17920 and enumeration literals.
17921 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17922 priority ranges are correct, verify compatibility against task
17923 dispatching and locking policies, and if everything is correct an entry
17924 is added to the table containing priority specific dispatching entries
17925 for this compilation unit.
17926 (Delay_Config_Pragma_Analyze): Delay processing
17927 Priority_Specific_Dispatching pragmas because when processing the
17928 pragma we need to access run-time data, such as the range of
17929 System.Any_Priority.
17930 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17931 Allow pragma Unreferenced as a context item
17932 Add pragma Preelaborable_Initialization
17933 (Analyze_Pragma, case Interface): Interface is extended so that it is
17934 now syntactically and semantically equivalent to Import.
17935 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17936 insertion characters.
17937 Add handling for Pragma_Wide_Character_Encoding
17938 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17939 never supercedes a real restriction, and that a real restriction
17940 always supercedes a warning.
17941 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
17944 2006-10-31 Bob Duff <duff@adacore.com>
17945 Ed Schonberg <schonberg@adacore.com>
17946 Robert Dewar <dewar@adacore.com>
17948 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17949 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17950 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17952 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17953 type of the function containing a return statement, because the
17954 Return_Type field was removed. We now use the Return_Applies_To field.
17956 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17957 (Build_Task_Image_Decl): If procedure is not called from an
17958 initialization procedure, indicate that function that builds task name
17959 uses the sec. stack. Otherwise the enclosing initialization procedure
17960 will carry the indication.
17961 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17962 N_Object_Declaration instead.
17963 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17964 conditional dead code killed, and change implementation accordingly.
17965 (Insert_Actions): Add N_Return_Object_Declaration case.
17966 Correct comment to mention N_Extension_Aggregate node.
17967 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17968 attempts to save information for global variables which cannot be
17970 (Get_Current_Value_Condition): Handle conditions the other way round
17971 (constant on left). Also handle right operand of AND and AND THEN
17972 (Set_Current_Value_Condition): Corresponding changes
17973 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17974 (Get_Current_Value_Condition): Handle simple boolean operands
17975 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17976 (Get_Current_Value_Condition): If the variable reference is within an
17977 if-statement, does not appear in the list of then_statments, and does
17978 not come from source, treat it as being at unknown location.
17979 (Get_Current_Value_Condition): Enhance to allow while statements to be
17980 processed as well as if statements.
17981 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17983 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17984 of loop. This is safe now that we fixed Kill_Current_Values.
17985 (OK_To_Do_Constant_Replacement): Check whether current scope is
17986 Standard, before examining outer scopes.
17988 2006-10-31 Vincent Celier <celier@adacore.com>
17990 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17991 When True, apply VMS treatment to children of packages A, G, I and S.
17994 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17996 2006-10-31 Robert Dewar <dewar@adacore.com>
17997 Ed Schonberg <schonberg@adacore.com>
17999 * freeze.adb: Add handling of Last_Assignment field
18000 (Warn_Overlay): Supply missing continuation marks in error msgs
18001 (Freeze_Entity): Add check for Preelaborable_Initialization
18003 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18005 * g-expect.adb: Add Warnings (Off) to prevent new warning
18007 * lib-xref.adb: Add handling of Last_Assignment field
18008 (Generate_Reference): Centralize handling of pragma Obsolescent here
18009 (Generate_Reference): Accept an implicit reference generated for a
18010 default in an instance.
18011 (Generate_Reference): Accept a reference for a node that is not in the
18012 main unit, if it is the generic body corresponding to an subprogram
18015 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18017 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18019 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18021 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18022 use clauses, to avoid messages on packages used to qualify, and also
18023 to avoid messages from obsolescent units.
18024 (Warn_On_Useless_Assignments): Don't generate messages for imported
18025 and exported variables.
18026 (Warn_On_Useless_Assignments): New procedure
18027 (Output_Obsolescent_Entity_Warnings): New procedure
18028 (Check_Code_Statement): New procedure
18030 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18031 Change name Is_Ada_2005 to Is_Ada_2005_Only
18032 (Last_Assignment): New field for useless assignment warning
18034 2006-10-31 Olivier Hainque <hainque@adacore.com>
18036 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18037 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18039 2006-10-31 Bob Duff <duff@adacore.com>
18040 Robert Dewar <dewar@adacore.com>
18041 Ed Schonberg <schonberg@adacore.com>
18043 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18044 Ada 95 mode, because it violates the new rules for AI-318.
18046 * g-awk.ads: Use overloaded subprograms in every case where we used to
18047 have a default of Current_Session. This makes the code closer to be
18048 correct for both Ada 95 and 2005.
18050 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18051 code, relying on the fact that the compiler generates a warning
18052 instead of an error in -gnatg mode.
18054 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18055 E_Return_Statement entity kind.
18056 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18058 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18059 report an error if the reserved word abstract has been previously found.
18060 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18062 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18063 parenthesized range attribute usage
18064 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18066 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18067 in the syntax for extended_return_statement. This is not in the latest
18068 RM, but the ARG is expected to issue an AI allowing this.
18069 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18070 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18071 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18072 P_Return_Statement): Parse the new syntax for extended_return_statement.
18074 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18075 Output_End_Missing): Add error-recovery code for the new
18076 extended_return_statement syntax; that is, the new E_Return entry on
18079 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18080 limited to nonlimited, because otherwise we violate the new Ada 2005
18081 rules about returning limited types in function Create_AST_Handler in
18084 * sem.adb (Analyze): Add cases for new node kinds
18085 N_Extended_Return_Statement and N_Return_Object_Declaration.
18087 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18088 type is in the same category as type of context before applying check,
18089 to prevent anomalies in instantiations.
18090 (Resolve_Aggregate): Remove test for limited components in aggregates.
18091 It's unnecessary in Ada 95, because if it has limited components, then
18092 it must be limited. It's wrong in Ada 2005, because limited aggregates
18094 (Resolve_Record_Aggregate): Move check for limited types later, because
18095 OK_For_Limited_Init requires its argument to have been resolved.
18096 (Get_Value): When copying the component default expression for a
18097 defaulted association in an aggregate, use the sloc of the aggregate
18098 and not that of the original expression, to prevent spurious
18099 elaboration errors, when the expression includes function calls.
18100 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18101 were missing. We also didn't handle qualified expressions. Now also
18102 allow function calls. Use new common routine OK_For_Limited_Init.
18103 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18104 with space can upper case letter).
18106 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18107 Has_Static_Discriminants flag
18108 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18109 type with discriminants.
18110 (Process_Range_Expr_In_Decl): Do validity checks on range
18111 (Build_Discriminant_Constraints): Use updated form of
18112 Denotes_Discriminant.
18113 (Process_Subtype): If the subtype is a private subtype whose full view
18114 is a concurrent subtype, introduce an itype reference to prevent scope
18116 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18117 Record_Type_Declaration): The functionality of the subprograms
18118 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18119 is now performed by a single routine.
18120 (Build_Derived_Record_Type): If the type definition includes an explicit
18121 indication of limitedness, then the type must be marked as limited here
18122 to ensure that any access discriminants will not be treated as having
18123 a local anonymous access type.
18124 (Check_Abstract_Overriding): Issue a detailed error message when an
18125 abstract subprogram was not overridden due to incorrect mode of its
18127 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18128 synchronized private extension declarations. Verify that the ancestor is
18129 a limited or synchronized interface or in the generic case, the ancestor
18130 is a tagged limited type or synchronized interface and all progenitors
18131 are either limited or synchronized interfaces.
18132 Derived_Type_Declaration): Check for presence of private extension when
18133 dealing with synchronized formal derived types.
18134 Process_Full_View): Enchance the check done on the usage of "limited" by
18135 testing whether the private view is synchronized.
18136 Verify that a synchronized private view is completed by a protected or
18138 (OK_For_Limited_Init_In_05): New function.
18139 (Analyze_Object_Declaration): Move check for limited types later,
18140 because OK_For_Limited_Init requires its argument to have been resolved.
18141 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18142 in order to alleviate the upward compatibility introduced by AI-318.
18143 (Constrain_Corresponding_Record): If the constraint is for a component
18144 subtype, mark the itype as frozen, to avoid out-of-scope references to
18145 discriminants in the back-end.
18146 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18147 this subprogram against wrong sources.
18148 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18149 discriminant of limited type completed with a protected type, when the
18150 discriminant is used to constrain a private component of the type, and
18151 expansion is disabled.
18152 (Find_Type_Of_Object): Do not treat a return subtype that is an
18153 anonymous subtype as a local_anonymous_type, because its accessibility
18154 level is the return type of the enclosing function.
18155 (Check_Initialization): In -gnatg mode, turn the error "cannot
18156 initialize entities of limited type" into a warning.
18157 (OK_For_Limited_Init): Return true for generated nodes, since it
18158 sometimes violates the legality rules.
18159 (Make_Incomplete_Declaration): If the type for which an incomplete
18160 declaration is created happens to be the currently visible entity,
18161 preserve the homonym chain when removing it from visibility.
18162 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18163 inherited subprograms.
18164 (Access_Definition): If this is an access to function that is the return
18165 type of an access_to_function definition, context is a type declaration
18166 and the scope of the anonymous type is the current one.
18167 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18168 incomplete subtype to the set of private dependents of the original
18170 (Constrain_Discriminated_Type): Emit an error message whenever an
18171 incomplete subtype is being constrained.
18172 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18173 corresponding subtype of the full view of the original incomplete type.
18174 (Check_Incomplete): Properly detect invalid usage of incomplete types
18177 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18179 * g-catiio.ads, g-catiio.adb (Value): New function.

18185 Integer_Address arithmetic, as in Set_Valid.
18187 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18188 Robert Dewar <dewar@adacore.com>
18190 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18191 handling executable extension manually and duplicating code.
18193 * make.adb: Implement new -S switch
18194 (Gnatmake): Use new function Osint.Executable_Name instead
18195 of handling executable extension manually.
18197 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18198 is specified, the executable name ends with this suffix.
18199 Take advantage of Osint.Executable_Name instead of duplicating code.
18201 * switch-m.adb: Recognize new gnatmake -S switch
18203 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18205 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18208 * makeusg.adb: Add line for gnatmake -S switch
18210 2006-10-31 Vincent Celier <celier@adacore.com>
18212 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18213 call it with -static-libgcc, as there are some platforms, such as
18214 Darwin, where one of these two switches is compulsory to link.
18216 2006-10-31 Vincent Celier <celier@adacore.com>
18218 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18219 instead of ADA_PROJECT_PATH, for the project path.
18220 (Gnatls): When displaying the project path directories, use host dir
18223 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18224 names in the project path, as absolute paths may correspond to
18225 multi-valued VMS logical names.
18227 2006-10-31 Vincent Celier <celier@adacore.com>
18229 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18230 absolute path name.
18231 (Locate_Regular_File): Ditto
18232 (Change_Dir): Remove, no longer used
18233 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18234 on Windows. Get it calling Get_Current_Dir.
18235 (OpenVMS): Remove imported boolean, no longer needed.
18236 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18237 (Pid_To_Integer): New function to convert a Process_Id to Integer
18239 2006-10-31 Thomas Quinot <quinot@adacore.com>
18241 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18242 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18244 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18247 2006-10-31 Robert Dewar <dewar@adacore.com>
18249 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18250 initial letter o as a zero.
18252 2006-10-31 Robert Dewar <dewar@adacore.com>
18254 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18256 2006-10-31 Robert Dewar <dewar@adacore.com>
18258 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18260 (Layout_Variant_Record): Retrieve the discriminants from the entity
18261 rather than from the type definition, because in the case of a full
18262 type for a private type we need to take the discriminants from the
18264 (Layout_Component_List): When applying the Max operator to variants with
18265 a nonstatic size, check whether either operand is static and scale that
18266 operand from bits to storage units before applying Max.
18267 (Layout_Type): In VMS, if a C-convention access type has no explicit
18268 size clause (and does not inherit one in the case of a derived type),
18269 then the size is reset to 32 from 64.
18271 2006-10-31 Vincent Celier <celier@adacore.com>
18273 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18274 its file has already been loaded, according to the unit being loaded,
18275 not to the current value of Multiple_Unit_Index.
18277 2006-10-31 Thomas Quinot <quinot@adacore.com>
18278 Eric Botcazou <ebotcazou@adacore.com>
18279 Arnaud Charlet <charlet@adacore.com>
18281 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18282 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18284 (a-except.o): Pass it to the compiler.
18285 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18286 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18287 a-calend-mingw.adb version.
18289 * Makefile.rtl: Added s-dsaser.
18290 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18291 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18292 Ada.Dispatching.Round_Robin.
18293 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18295 * Make-lang.in: Remove all references to gt-ada-decl.h.
18296 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18298 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18299 Update dependencies.
18301 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18303 2006-10-31 Vincent Celier <celier@adacore.com>
18305 * mlib-utl.adb (Initialized): Remove, no longer used
18306 (Initialize): Remove, no longer used
18307 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18308 if there is one, the archive indexer. Fail if the archive builder cannot
18310 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18313 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18315 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18316 Process_Body_Clauses): If the context of a body includes a use clause
18317 for P.Q then a with_clause for P in the same body is not redundant,
18318 even if the spec also has a with_clause on P.
18319 Add missing continuation mark to error msg
18320 (Build_Limited_Views): A limited view of a type is tagged if its
18321 declaration includes a record extension.
18322 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18323 node, even if the subunit has errors. This avoids malfunction by
18324 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18325 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18326 generation of obsolescent messages for with statements (cannot do
18327 this too early, or we cannot implement avoiding the messages in the
18328 case of obsolescent units withing obsolescent units).
18329 (Install_Siblings): If the with_clause is on a remote descendant of
18330 an ancestor of the current compilation unit, find whether there is
18331 a sibling child unit that is immediately visible.
18332 (Remove_Private_With_Clauses): New procedure, invoked after completing
18333 the analysis of the private part of a nested package, to remove from
18334 visibility the private with_clauses of the enclosing package
18336 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18337 now centralized in Generate_Reference.
18338 (Install_Limited_Context_Clauses): Remove superfluous error
18339 message associated with unlimited view visible through use
18340 and renamings. In addition, at the point in which the error
18341 is reported, we add the backslash to the text of the error
18342 to ensure that it is reported as a single error message.
18343 Use new // insertion for some continuation messages
18344 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18345 to create implicit with_clause for parent unit mentioned in original
18346 limited_with_clause.
18347 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18348 unit is a child unit. For ASIS queries.
18349 (Analyze_Subunit): If the subunit appears within a child unit, make all
18350 ancestor child units directly visible again.
18352 2006-10-31 Robert Dewar <dewar@adacore.com>
18354 * par-ch10.adb (P_Context_Clause): Minor error message fix

18362 Add the new actual Abstract_Present to every call to
18363 P_Interface_Type_Definition.
18364 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18365 a formal object declaration with an access definition or a subtype mark
18366 with a null exclusion.
18367 (P_Generic_Association): Handle association with box, and others_choice
18368 with box, to support Ada 2005 partially parametrized formal packages.

18373 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18374 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18375 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18376 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18377 private extensions.
18378 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18379 to P_Interface_Type_Definition.
18380 (P_Interface_Type_Definition): Addition of one formal to report an error
18381 if the reserved word abstract has been previously found.
18382 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18383 object renaming declaration with an access definition or subtype mark
18384 with a possible null exclusion.

18403 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18406 2006-10-31 Vincent Celier <celier@adacore.com>
18408 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18409 on VMS, change "__" to '.' before checking the name.

18411 of sources, even if it is not the first time, as it is for another
18413 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18414 dot, instead of replacing only the first '_'.
18416 * prj-part.adb (Parse): Convert project file path to canonical form
18418 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18419 extended, the project id of the project extending it is recorded in its
18420 data, even when it has already been processed as an imported project.
18422 2006-10-31 Robert Dewar <dewar@adacore.com>
18424 * repinfo.adb (List_Entities): Don't list entities from renaming
18427 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18428 Robert Dewar <dewar@adacore.com>
18430 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18431 only a restriction warning is active for the given restriction. This is
18432 desirable because we do not want to modify code in the case where only
18434 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18435 causes overriding of real restrictions.
18436 Take advantage of new No_Restrictions constant.
18438 * raise.h: (__gnat_set_globals): Change profile.
18440 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18442 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18445 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18446 Move all the entities in obsolete package System.PolyORB_Interface to
18447 System.Partition_Interface.
18448 (RE_Storage_Size): New function in System.Tasking.
18449 (RE_Get_Ceiling): New entity.

18465 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18466 properly an attempt to apply Unchecked_Access to a protected operation.
18467 (OK_Self_Reference): New subprogram to check the legality of an access
18468 attribute whose prefix is the type of an enclosing aggregate.
18469 Generalizes previous mechanism to handle attribute references nested
18470 arbitrarily deep within the aggregate.
18471 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18472 can appear in an aggregate if this is a default-initialized aggregate
18473 for a self-referential type.
18474 (Resolve_Attribute, case Access): Ditto.
18475 Add support for new implementation defined attribute Stub_Type.
18476 (Eval_Attribute, case Attribute_Stub_Type): New case.
18477 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18478 (Stream_Attribute_Available): Implement using new subprogram from
18479 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18480 Has_Specified_Stream_Attribute flag.
18481 Disallow Storage_Size and Storage_Pool for access to subprogram
18482 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18483 access types of return subtypes in extended return statements. Remove
18484 accessibility checks on anonymous access types when Unchecked_Access is
18486 (Analyze_Attribute): Add support for the use of 'Class to convert
18487 a class-wide interface to a tagged type.
18488 Add support for the attribute Priority.
18489 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18490 whether the designated type is discriminated with a constrained partial
18491 view and require static matching in that case.
18492 Add local variable Des_Btyp. The Designated_Type
18493 of an access to incomplete subtype is either its non-limited view if
18494 coming from a limited with or its etype if regular incomplete subtype.
18496 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18497 Fix predicate to identify and allow cases of (expander-generated)
18498 references to tag of designated object of a RACW.
18499 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18500 non-static, and therefore cannot appear as a primary in a preelaborable
18502 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18503 Has_Read_Write_Attributes.
18504 (Has_Read_Write_Attributes): Reimplement in termes of
18505 Has_Stream_Attribute_Definition.
18506 (Missing_Read_Write_Attributes): When checking component types in a
18507 record, unconditionally call Missing_Read_Write_Attributes recursively
18508 (remove guard checking for Is_Record_Type / Is_Access_Type).
18510 2006-10-31 Robert Dewar <dewar@adacore.com>
18512 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18513 useless assignments here and conditionalize it on absence of exception
18515 (Analyze_Exception_Handlers): Small code reorganization of error
18516 detection code, for new handling of formal packages.
18518 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18519 Hristian Kirtchev <kirtchev@adacore.com>
18521 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18522 that has been constant-folded, preserve information of original tree,
18524 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18525 generated private extension declaration if the formal derived type is
18526 synchronized. Carry synchronized present over to the generated private
18528 (Validate_Derived_Type_Instance): Ensure that the actual of a
18529 synchronized formal derived type is a synchronized tagged type.
18530 (Instantiate_Formal_Package): When creating the instantiation used to
18531 validate the actual package of a formal declared without a box, check
18532 whether the formal itself depends on a prior actual.
18533 (Instantiate_Formal_Subprogram): Create new entities for the defining
18534 identifiers of the formals in the renaming declaration, for ASIS use.
18535 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18536 a renaming declaration or a subtype declaration for an actual in an
18537 instance, capture location information of declaration in generic, for
18539 (Instantiate_Formal_Package): Add comments on needed additional tests.
18540 AI-317 (partial parametrization) is fully implemented.
18541 (Validate_Private_Type_Instance): Add check for actual which
18542 must have preelaborable initialization
18543 Use new // insertion for some continuation messages
18544 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18545 Default_Expression. Add type retrieval when the declaration has an
18546 access definition. Update premature usage of incomplete type check.
18547 (Check_Access_Definition): New subsidiary routine. Check whether the
18548 current compilation version is Ada 05 and the supplied node has an
18550 (Instantiate object): Alphabetize local variables. Handle the creation
18551 of new renaming declarations with respect to the kind of definition
18552 used - either an access definition or a subtype mark. Guard against
18553 unnecessary error message in the context of anonymous access types after
18554 they have been resolved. Add check for required null exclusion in a
18555 formal object declaration.
18556 (Switch_View): A private subtype of a non-private type needs to be
18557 switched (the base type can have been switched without its private
18558 dependents because of the last branch of Check_Private_View.
18559 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18561 (Instantiate_Type): Emit an error message whenever a class-wide type of
18562 a tagged incomplete type is used as a generic actual.
18563 (Find_Actual_Type): Extend routine to handle a component type in a child
18564 unit that is imported from a formal package in a parent.
18565 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18566 agree on constrainedness, rather than checking against ultimate ancestor
18567 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18568 generic body, for navigation purposes.
18570 2006-10-31 Robert Dewar <dewar@adacore.com>
18571 Thomas Quinot <quinot@adacore.com>
18573 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18575 (New_Stream_Subprogram): When processing an attribute definition clause
18576 for a stream-oriented subprogram, record an entity node occurring at
18577 the point of clause to use for checking the visibility of the clause,
18578 as defined by 8.3(23) as amended by AI-195.
18579 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18580 New_Stream_Function and New_Stream_Procedure.
18581 (New_Stream_Function, New_Stream_Procedure): Removed.
18582 (Analyze_Attribute_Definition_Clause, case Address): Check new
18583 Alignment_Check check
18585 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18586 Javier Miranda <miranda@adacore.com>
18587 Robert Dewar <dewar@adacore.com>
18589 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18590 generate the same errors compiling under -gnatc.
18591 (Try_Object_Operation): If no candidate interpretation succeeds, but
18592 there is at least one primitive operation with the right name, report
18593 error in call rather than on a malformed selected component.
18594 (Analyze_Selected_Component): If the prefix is an incomplete type from
18595 a limited view, and the full view is available, use the full view to
18596 determine whether this is a prefixed call to a primitive operation.
18597 (Operator_Check): Verify that a candidate interpretation is a binary
18598 operation before checking the type of its second formal.
18599 (Analyze_Call): Add additional warnings for function call contexts not
18601 (Analyze_Allocator): Move the check for "initialization not allowed for
18602 limited types" after analyzing the expression. This is necessary,
18603 because OK_For_Limited_Init looks at the structure of the expression.
18604 Before analysis, we don't necessarily know what sort of expression it
18605 is. For example, we don't know whether F(X) is a function call or an
18606 indexed component; the former is legal in Ada 2005; the latter is not.
18607 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18608 were missing. We also didn't handle qualified expressions. Now also
18609 allow function calls. Use new common routine OK_For_Limited_Init.
18610 (Analyze_Type_Conversion): Do not perform some legality checks in an
18611 instance, because the error message will be redundant or spurious.
18612 (Analyze_Overloaded_Selected_Component): Do not do style check when
18613 setting an entity, since we do not know it is the right entity yet.
18614 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18615 (Analyze_Overloaded_Selected_Component): Same change
18616 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18617 since regular incomplete subtypes are transformed into corresponding
18618 subtypes of their full views.
18619 (Complete_Object_Operation): Treat name of transformed subprogram call
18620 as coming from source, for browsing purposes.
18621 (Try_Primitive_Operation): If formal is an access parameter, compare
18622 with base type of object to determine whether it is a primitive
18624 (Operator_Check): If no interpretation of the operator matches, check
18625 whether a use clause on any candidate might make the operation legal.
18626 (Try_Class_Wide_Operation): Check whether the first parameter is an
18627 access type whose designated type is class-wide.
18629 2006-10-31 Robert Dewar <dewar@adacore.com>
18630 Ed Schonberg <schonberg@adacore.com>

18634 warn on infinite loops.
18635 Add \\ to some continuation messages
18636 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18637 (Process_Bounds): If the bounds are integer literals that result from
18638 constant-folding, and they carry a user-defined type, preserve that type
18639 rather than treating this as an integer range.
18640 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18641 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18642 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18643 left hand side of assignment.
18644 (Analyze_Assignment): Add suport to manage assigments to the attribute
18645 priority of a protected object.
18646 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18647 not just identifiers.
18648 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18649 or AND THEN for possible tracking.
18650 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18651 case of while loops so we can track values in the loop body.
18653 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18654 Hristian Kirtchev <kirtchev@adacore.com>
18655 Bob Duff <duff@adacore.com>
18657 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18658 procedure cannot be a protected operation (it is a basic_declaration,
18659 not a subprogram_declaration).
18660 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18661 Subp. Add logic for entry processing.
18662 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18663 Determine whether an entry or subprogram of a protected or task type
18664 override an inherited primitive of an implemented interface.
18665 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18666 Update the actual used in calls to Check_Overriding_Indicator.
18667 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18668 generate the proper reference to the parent unit, for cross-reference.
18669 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18671 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18672 (Add_Extra_Formal): Revise procedure to allow passing in associated
18673 entity, scope, and name suffix, and handle setting of the new
18674 Extra_Formals field.
18675 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18676 pass new parameters. Add support for adding the new extra access formal
18677 for functions whose calls are treated as build-in-place.
18678 (Analyze_A_Return_Statement): Correct casing in error message.
18679 Move Pop_Scope to after Analyze_Function_Return, because an extended
18680 return statement really is a full-fledged scope. Otherwise, visibility
18681 doesn't work right. Correct use of "\" for continuation messages.
18682 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18683 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18684 the node doesn't get properly marked as analyzed.
18685 (Analyze_Subprogram_Body): If subprogram is a function that returns
18686 an anonymous access type that denotes a task, build a Master Entity
18688 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18689 proper usage of null exclusion in a result definition.
18690 (Process_Formals): Code cleanup and new error message.
18691 (Process_Formals): Detect incorrect application of null exclusion to
18693 (Conforming_Types): Handle conformance between [sub]types and itypes
18694 generated for entities that have null exclusions applied to them.
18695 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18696 base type is an access subtype. This case arrises with null exclusions.
18697 (New_Overloaded_Entity): Do not remove the overriden entity from the
18698 homonym chain if it corresponds with an abstract interface primitive.
18699 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18700 call to the synthesized predicate Is_Incomplete_Type.
18701 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18703 (Analyze_Subprogram_Declaration): Check that abstract interface
18704 primitives are abstract or null.
18705 (Analyze_Subprogram_Specification): Remove previous check for abstract
18706 interfaces because it was not complete.
18707 (Has_Interface_Formals): Removed.
18709 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18710 Javier Miranda <miranda@adacore.com>
18712 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18713 of Analyze_Package_Body, to create Itype references for anonymous
18714 access types created in the package declaration, whose designated types
18715 may have only a limited view.
18716 (Analyze_Package_Specification): For the private part of a nested
18717 package, install private_with_clauses of enclosing compilation unit if
18718 we are in its visible part.
18719 (Declare_Inherited_Private_Subprograms): Complete barrier
18720 to ensure that the primitive operation has an alias to some parent
18721 primitive. This is now required because, after the changes done for the
18722 implementation of abstract interfaces, the contents of the list of
18723 primitives has entities whose alias attribute references entities of
18724 such list of primitives.
18725 (Analyze_Package_Specification): Simplify code that handles parent units
18726 of instances and formal packages.
18727 (Uninstall_Declarations): Check the convention consistency among
18728 primitive overriding operations of a tagged record type.
18730 2006-10-31 Robert Dewar <dewar@adacore.com>

18737 expected and found set right)
18738 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18739 (Analyze_Generic_Renaming): Same fix
18740 (Use_One_Package): Do not take into account the internal entities of
18741 abstract interfaces during the analysis of entities that are marked
18742 as potentially use-visible.
18743 (Find_Type): Handle the case of an attribute reference for
18744 implementation defined attribute Stub_Type (simply let the analysis of
18745 the attribute reference rewrite it).
18746 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18747 type that appears in a Use_Type clause.
18748 (Analyze_Object_Renaming): Add support for renaming of the Priority
18750 (Find_Type): In Ada 2005, a task type can be used within its own body,
18751 when it appears in an access definition.
18752 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18753 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18754 in a formal object declaration or in a subtype declaration.
18755 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18756 (Check_Null_Exclusion): New local routine to
18757 Analyze_Subprogram_Renaming. Check whether the formals and return
18758 profile of a renamed subprogram have required null exclusions when
18759 their counterparts of the renaming already impose them.
18760 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18761 Determine whether an entity is inside a generic scope.
18762 (In_Open_Scope): First pass of documentation update.
18763 (Find_Expanded_Name): Add support for shadow entities associated with
18764 limited withed packages. This is required to handle nested packages.
18765 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18766 that makes a renaming of a limited withed package illegal.

18769 Ed Schonberg <schonberg@adacore.com>
18771 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18772 Check_Overriding_Indicator.
18773 (Analyze_Task_Definition): Ditto.
18774 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18775 (Check_Overriding_Indicator): To find overridden interface operation,
18776 examine only homonyms that have an explicit subprogram declaration, not
18777 inherited operations created by an unrelated type derivation.
18778 (Check_Overriding_Indicator): When checking for the presence of "null"
18779 in a procedure, ensure that the queried node is a procedure
18781 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18782 type when the formal is an access to variable.
18783 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18784 (Analyze_Task_Type): Same addition
18785 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18786 provide navigation capabilities for entries.

18790 Javier Miranda <miranda@adacore.com>
18791 Gary Dismukes <dismukes@adacore.com>
18793 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18794 inherited from an interface ancestor by another interface in the
18795 context of an instance as 'late'.
18796 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18797 of a call to a function that dispatches on access result.
18798 (Check_Dispatching_Operation): In case of late overriding of a primitive
18799 that covers abstract interface subprograms we register it in all the
18800 secondary dispatch tables associated with abstract interfaces.
18801 (Check_Dispatching_Call): Add check that a dispatching call is not made
18802 to a function with a controlling result of a limited type. This is a
18803 current implementation restriction.
18804 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18805 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18806 argument is an interface type that is a generic formal.
18807 (Is_Interface_Subprogram): Removed.
18808 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18809 operation, check the formals to handle the case in which it is
18810 associated with an abstract interface type.

19623 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19624 abstract interface type, the static analysis is not enough to know if
19625 the interface is implemented or not by the source tagged type. Hence
19626 we must pass the work to the expander to generate the required code to
19627 evaluate the conversion at run-time.
19628 (Resolve_Equality_Op): Do not apply previous
19629 transformation if expansion is disasbled, to prevent anomalies when

20268 * checks.adb (Build_Discriminant_Checks): If the expression being
20269 checks is an aggregate retrieve the values of its discriminants to
20270 generate the check, rather than creating a temporary and a reference
20272 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
20273 (Install_Null_Excluding_Check): Ditto
20274 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,
20275 not for the renamed object, so that the actual itype is attached in the

20287 error message with the full switch.
20288 Eliminate numeric switches for binder/gnatmake
20290 * switch.ads, switch.adb (Bad_Switch): New procedure
20292 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20293 Remove 0-9 as debug flag character possibilities
20294 -d is now controlling the primary stack size when its value is a
20295 positive. Also add checks against invalid values, and support for kb,
20296 mb. Ditto for -D switch.
20298 2006-02-13 Robert Dewar <dewar@adacore.com>
20299 Serguei Rybin <rybin@adacore.com>
20301 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20302 save/restore routines.
20303 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20304 were not always properly handled previously.
20305 Since we are changing the tree format anyway, also get rid of the
20306 junk obsolete Immediate_Errors flag.
20307 (Tree_Read): Change the way of reading Tree_Version_String - now we
20308 read the version string from the tree even if its length is not the
20309 same as the length of the version string computed from Gnatvsn.
20310 (Search_Directory_Present): New Boolean flag for the compiler.
20311 Define Tree_Version_String as a dynamic string.
20312 (Default_Stack_Size): new variable, used to handle switch -d.
20315 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20316 only for main unit.
20317 Add pragma Ada_2005 (synonym for Ada_05)
20318 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20319 were not always properly handled previously.
20321 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20322 explicit Ada_95 to Ada_2005.
20324 2006-02-13 Javier Miranda <miranda@adacore.com>
20325 Robert Dewar <dewar@adacore.com>
20326 Ed Schonberg <schonberg@adacore.com>
20328 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20329 against errors in the source program: a private types for which the
20330 corresponding full type declaration is missing and pragma CPP_Virtual
20332 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20333 (Is_Known_Null): New flag
20334 (Has_Pragma_Pure): New flag
20335 (No_Return): Present in all entities, set only for procedures
20336 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20337 explicitly declared limited.
20338 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20339 entities. Only used for component marked Is_Tag. If present it stores
20340 the Offset_To_Top function used to provide this value in tagged types
20341 whose ancestor has discriminants.
20343 * exp_ch2.adb: Update status of new Is_Known_Null flag
20345 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20347 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20348 the categorization sense if Is_Pure was set by pragma Pure_Function.
20350 2006-02-13 Quentin Ochem <ochem@adacore.com>
20351 Olivier Hainque <hainque@adacore.com>
20353 * bindusg.adb: Updated documentation for -d and -D switches.
20355 * raise.h (__gnat_set_globals): added new parameter for
20356 Default_Stack_Size.
20358 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20359 (__gnat_handle_vms_condition): Adjust context before raise.
20360 (__gnat_install_handler): Restore the global vector setup for GCC
20361 versions before 3.4, as the frame based circtuitry is not available
20363 (__gnat_set_globals): added a parameter default_stack_size
20364 (__gl_default_stack_size): new variable.
20366 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20368 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20369 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20370 does not exist in the Ada RM.
20371 (Compatible_Int_Bounds): Determine whether two integer range bounds
20372 are of equal length and have the same start and end values.
20373 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20374 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20375 aggregate when it is part of an object declaration.
20376 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20377 constrains discriminants of its parent, add explicitly the discriminant
20378 constraints of the ancestor by retrieving them from the
20379 stored_constraint of the parent.
20381 2006-02-13 Robert Dewar <dewar@adacore.com>
20383 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20384 attribute Mechanism_Code is applied to renamed subprogram, modify
20385 prefix to point to base subprogram.
20386 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20388 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20389 renamed subprograms so that the front-end must replace the prefix
20392 2006-02-13 Javier Miranda <miranda@adacore.com>
20393 Gary Dismukes <dismukes@adacore.com>
20395 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20396 availability of RE_Interface_Tag.
20397 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20398 (Freeze_Record_Type): Do not generate the tables associated with
20399 timed and conditional dispatching calls through synchronized
20400 interfaces if compiling under No_Dispatching_Calls restriction.
20401 When compiling for Ada 2005, for a nonabstract
20402 type with a null extension, call Make_Controlling_Function_Wrappers
20403 and insert the wrapper function declarations and bodies (the latter
20404 being appended as freeze actions).
20405 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20406 predefined primitives associated with timed and conditional
20407 dispatching calls through synchronized interfaces if we are
20408 compiling under No_Dispatching_Calls.
20409 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20410 service is available before generating a call.
20411 (Make_Controlling_Function_Wrappers): New procedure.
20412 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20413 access-to-limited-interfaces because they can be used to reference
20414 tasks that implement such limited interface.
20415 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20416 procedure spec and body of the Offset_To_Top function that is generated
20417 when the parent of a type with discriminants has secondary dispatch
20419 (Init_Secondary_Tags): Handle the case in which the parent of the type
20420 containing secondary dispatch tables has discriminants to generate the
20421 correct arguments to call Set_Offset_To_Top.
20422 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20424 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20425 Add Wide_[Wide_]Expanded_Name.
20426 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20427 the same functionality of Get_Prim_Op_Address but applied to predefined
20428 primitive operations because the pointers to the predefined primitives
20429 are now saved in a separate table.
20430 (Parent_Size): Modified to get access to the separate table of primitive
20431 operations or the parent type.
20432 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20433 functionality of Set_Prim_Op_Address but applied to predefined primitive
20435 (Set_Signature): New subprogram used to store the signature of a DT.
20436 (Displace): If the Offset_To_Top value is not static then call the
20437 function generated by the expander to get such value; otherwise use
20438 the value stored in the table of interfaces.
20439 (Offset_To_Top): The type of the actual has been changed to Address to
20440 give the correct support to tagged types with discriminants. In this
20441 case this value is stored just immediately after the tag field.
20442 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20443 offset_to_top value is static and hence pass this value to the run-time
20444 to store it in the table of interfaces, or else if this value is dynamic
20445 and then pass to the run-time the address of a function that is
20446 generated by the expander to provide this value for each object of the
20449 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20450 (Default_Prim_Op_Count): New entity
20451 (Get_Predefined_Prim_Op_Address): New entity
20452 (Set_Predefined_Prim_Op_Address): New entity
20453 (RE_Set_Signature): New entity
20455 2006-02-13 Thomas Quinot <quinot@adacore.com>
20456 Ed Schonberg <schonberg@adacore.com>
20458 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20459 Make_Adjust_Call done for a newly-allocated object.
20461 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20462 in a subprogram are wrapped in a cleanup block, indicate that the
20463 subprogram contains an inner block with an exception handler.
20464 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20465 Adjust call is for a newly-allocated object. In that case we must not
20466 assume that the finalization list chain pointers are correct (since they
20467 come from a bit-for-bit copy of the original object's pointers) so if
20468 the attach level would otherwise be zero (no change), we set it to 4
20469 instead to cause the pointers to be reset to null.
20471 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20472 reset chain pointers to null.
20474 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20476 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20477 string, and the context requires a loop for the assignment (e.g.
20478 because the left-hand side is packed), generate a unique name for the
20479 temporary that holds the string, to prevent spurious name clashes.
20481 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20482 Javier Miranda <miranda@adacore.com>
20483 Robert Dewar <dewar@adacore.com>
20484 Gary Dismukes <dismukes@adacore.com>
20486 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20487 return unconstrained arrays.
20489 (Expand_Call): An indirect call through an access parameter of a
20490 protected operation is not a protected call.
20491 Add circuit to raise CE in Ada 2005 mode following call
20492 to Raise_Exception.
20493 (Register_DT_Entry): Do nothing if
20494 the run-time does not give support to abstract interfaces.
20495 (Freeze_Subprogram): In case of dispatching operations, do not generate
20496 code to register the operation in the dispatch table if the source
20497 is compiled with No_Dispatching_Calls.
20498 (Register_Predefined_DT_Entry): Generate code that calls the new
20499 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20500 Set_Prim_Op_Address.
20502 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20503 on array assignments if the right-hand side is a function call that has
20504 been inlined. Check is performed on the assignment in the block.
20505 (Process_Bounds): If bounds and range are overloaded, apply preference
20506 rule for root operations to disambiguate, and diagnose true ambiguity.
20507 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20508 a tag-indeterminate right-hand side even when Expander_Active is True.
20509 Needed to ensure that dispatching calls to T'Input are allowed and
20510 get the tag of the target class-wide object.
20512 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20513 an inherited primitive operation that already overrides several
20514 abstract interface primitives. For transitivity, the new entity must
20515 also override all the abstract interface primitives covered by the
20516 inherited overriden primitive.
20517 Emit warning if new entity differs from homograph in same scope only in
20518 that one has an access parameter and the other one has a parameter of
20519 a general access type with the same designated type, at the same
20520 position in the signature.
20521 (Make_Inequality_Operator): Use source locations of parameters and
20522 subtype marks from corresponding equality operator when creating the
20523 tree structure for the implicit declaration of "/=". This does not
20524 change anything in behaviour except that the decoration of the
20525 components of the subtree created for "/=" allows ASIS to get the
20526 string images of the corresponding identifiers.
20527 (Analyze_Return_Statement): Remove '!' in warning message.
20528 (Check_Statement_Sequence): Likewise.
20529 (Analyze_Subprogram_Body): For an access parameter whose designated type
20530 is an incomplete type imported through a limited_with clause, use the
20531 type of the corresponding formal in the body.
20532 (Check_Returns): Implicit return in No_Return procedure now raises
20533 Program_Error with a compile time warning, instead of beging illegal.
20534 (Has_Single_Return): Function returning unconstrained type cannot be
20535 inlined if expression in unique return statement is not an identifier.
20536 (Build_Body_To_Inline): It is possible to inline a function call that
20537 returns an unconstrained type if all return statements in the function
20538 return the same local variable. Subsidiary procedure Has_Single_Return
20539 verifies that the body conforms to this restriction.
20541 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20542 same type, and one of them is of an anonymous access type, convert
20543 the other operand to it, so that this is a valid binary operation for
20545 (Resolve_Type_Conversion): Handle subtypes of protected types and
20546 task types when accessing to the corresponding record type.
20547 (Resolve_Allocator): Add '\' in 2-line warning message.
20548 Remove '!' in warning message.
20549 (Resolve_Call): Add '\' in 2-line warning message.
20550 (Valid_Conversion): Likewise.
20551 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20552 resulting type may be an access type with an implicit dereference.
20553 Obtain the proper component from the designated type.
20554 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20555 given by an expanded name with prefix Standard, when the operands are
20556 of an anonymous access type.
20557 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20558 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20559 prefix of the expression is not of an incomplete type. Allows full
20560 diagnoses of all semantic errors.
20561 (Resolve_Actuals): If the actual is an allocator whose directly
20562 designated type is a class-wide interface we build an anonymous
20563 access type to use it as the type of the allocator. Later, when
20564 the subprogram call is expanded, if the interface has a secondary
20565 dispatch table the expander will add a type conversion to force
20566 the displacement of the pointer.
20567 (Resolve_Call): If a function that returns an unconstrained type is
20568 marked Inlined_Always and inlined, the call will be inlined and does
20569 not require the creation of a transient scope.
20570 (Check_Direct_Boolean_Op): Removed
20571 (Resolve_Comparison_Op): Remove call to above
20572 (Resolve_Equality_Op): Remove call to above
20573 (Resolve_Logical_Op): Inline above, since this is only call.
20574 (Valid_Conversion): Handle properly conversions between arrays of
20575 convertible anonymous access types.
20578 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20579 the literal in an unchecked conversion, because GCC 4.x needs a static
20580 value for a string bound.
20582 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20583 Hristian Kirtchev <kirtchev@adacore.com>
20585 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20586 components of the corresponding record, take into account component
20587 definitions that are access definitions.
20588 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20589 procedure is not considered a dispatching call and will be expanded
20592 2006-02-13 Javier Miranda <miranda@adacore.com>
20594 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20595 controlling argument of the dispatching call is an abstract interface
20596 class-wide type then we use it directly.
20597 Check No_Dispatching_Calls restriction.
20598 (Default_Prim_Op_Position): Remove the code that looks for the last
20599 entity in the list of aliased subprograms. This code was wrong in
20601 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20602 when the source is compiled with the No_Dispatching_Calls restriction.
20603 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20604 if we are compiling with restriction No_Dispatching_Calls.
20605 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20606 subprograms if we are compiling under No_Dispatching_Calls restriction.
20607 (Make_DT): Generate a dispatch table with a single dummy entry if
20608 we are compiling with the No_Dispatching_Calls restriction. In
20609 addition, in this case we don't generate code that calls to the
20610 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20611 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20612 of this subprogram if compiling with the No_Dispatching_Calls
20614 (Expand_Type_Conversion): Instead of using the actual parameter,
20615 the argument passed as parameter to the conversion function was
20616 erroneously referenced by the expander.
20617 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20618 Set_Predefined_Primitive_Op_Address and Set_Signature.
20619 (Expand_Dispatching_Call): Generate call to
20620 Get_Predefined_Prim_Op_Address for predefined primitives.
20621 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20622 predefined primitives.
20623 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20624 primitives we reserve one dummy entry to ensure that the tag does not
20625 point to some memory that is associated with some other object. In
20626 addition, remove all the old code that generated the assignments
20627 associated with the signature of the dispatch table and replace them
20628 by a call to the new subprogram Set_Signature.
20629 (Set_All_DT_Position): Change the algorithm because now we have a
20630 separate dispatch table associated with predefined primitive operations.
20631 (Expand_Interface_Conversion): In case of non-static offset_to_top
20632 add explicit dereference to get access to the object after the call
20633 to displace the pointer to the object.
20634 (Expand_Interface_Thunk): Modify the generation of the actual used
20635 in the calls to the run-time function Offset_To_Top to fulfil its
20637 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20639 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20641 * exp_dist.adb (Copy_Specification): For access parameters, copy
20642 Null_Exclusion flag, which will have been set for stream subprograms
20645 2006-02-13 Pascal Obry <obry@adacore.com>
20647 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20648 previous implementation was using the C runtime spawnve routine but
20649 the corresponding wait was using directly the Win32 API. This was
20650 causing some times a lock when waiting for an event using
20651 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20652 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20653 API fixes this problem.
20655 2006-02-13 Robert Dewar <dewar@adacore.com>
20657 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20660 2006-02-13 Thomas Quinot <quinot@adacore.com>
20662 * exp_pakd.ads: Fix typos in comments.
20664 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20665 array reference that is an explicit dereference, mark the converted
20666 (packed) array reference as analyzed to prevent a forthcoming
20667 reanalysis from resetting its type to the original (non-packed) array
20670 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20671 Javier Miranda <miranda@adacore.com>
20672 Eric Botcazou <ebotcazou@adacore.com>
20674 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20675 Is_Predefined_Primitive_Operation): When
20676 searching for the predefined equality operator, verify that operands
20677 have the same type.
20678 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20679 for the last entity in the list of aliased subprograms. This code
20680 was wrong in case of renamings.
20681 (Set_Renamed_Subprogram): New procedure
20682 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20683 Exp_Type constant computed when entering this subprogram.
20684 (Known_Null): New function
20685 (OK_To_Do_Constant_Replacement): New function
20686 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20687 (Side_Effect_Free): An attribute reference 'Input is not free of
20688 side effect, unlike other attributes that are functions. (from code
20690 (Remove_Side_Effects): Expressions that involve packed arrays or records
20691 are copied at the point of reference, and therefore must be marked as
20692 renamings of objects.
20693 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20694 not a dispatching operation.
20697 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20698 elementary types in all cases.
20700 2006-02-13 Javier Miranda <miranda@adacore.com>
20702 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20703 task types when accessing to the corresponding record type.
20704 Remove '!' in warning message.
20706 2006-02-13 Olivier Hainque <hainque@adacore.com>
20708 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20709 to avoid useless and space inefficient overalignments on targets where
20710 Max_Alignment is larger than 16.
20712 2006-02-13 Pascal Obry <obry@adacore.com>
20714 * g-catiio.adb (Sec_Number): New type used to compute the number of
20715 seconds since 1-1-1970.
20716 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20717 negative numbers (years, months...) it is better to have a Natural here.

20737 * gnatcmd.adb (Rules_Switches): New table
20738 (Add_To_Rules_Switches): New procedure
20739 (GNATCmd): For command CHECK, put all options following "-rules" in the
20740 Rules_Switches table. Append these -rules switches after the -cargs
20743 2006-02-13 Robert Dewar <dewar@adacore.com>
20745 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20746 These two cases were generating incorrect output, and if this unit
20747 was built with checks on, generated a discriminant mismatch constraint
20750 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20751 Robert Dewar <dewar@adacore.com>
20753 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20754 view is an array type, indicate the component type as well, for
20755 navigation purposes.
20756 (Generate_Reference): Don't consider array ref on LHS to be a case
20757 of violating pragma Unreferenced.
20758 Do not give Ada 2005 warning except on real reference.
20760 2006-02-13 Vincent Celier <celier@adacore.com>
20762 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20763 main source, add switch -mdebug-main=_ada_ so that the executable can
20764 be debugged by the standard VMS debugger.
20765 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20766 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20767 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20768 of the last source, as the binding and linking phases are never
20770 Set all executable obsolete when rebuilding a library.
20772 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20775 2006-02-13 Javier Miranda <miranda@adacore.com>
20778 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20779 code to improve the error message reported when the program has
20780 declarations of abstract interface types and it is not compiled with
20781 the -gnat05 switch.
20782 (P_Access_Definition): Reorganize the code to improve the error
20783 message reported when the new Ada 2005 syntax for anonymous
20784 access types is used and the program is not compiled with the

20807 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20808 unknown, use the location of the project to report the error.
20809 (When_No_Sources): New global variable
20810 (Report_No_Ada_Sources): New procedure
20811 (Check): New parameter When_No_Sources. Set value of global variable
20813 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20814 (Get_Sources_From_File): Ditto
20815 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20818 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20819 Call Prj.Proc.Process with parameter When_No_Sources.
20821 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20822 Call Recursive_Check with parameter When_No_Sources.
20823 (Recursive_Check): New parameter When_No_Sources. Call itself and
20824 Prj.Nmsc.Check with parameter When_No_Sources.
20825 (Process): New parameter When_No_Sources. Call Check with parameter
20827 (Copy_Package_Declarations): New procedure to copy renamed parameters
20828 and setting the location of the declared attributes to the location
20829 of the renamed package.

20835 * prj-makr.adb (Make): Preserve the comments from the original project
20837 When removing nodes (attributes Source_Dirs, Source_Files,
20838 Source_List_File and package Naming), save the comments and attach the
20839 saved comments to the newly created nodes.
20840 Do not add a with clause for the naming package if one already exists.
20842 2006-02-13 Javier Miranda <miranda@adacore.com>

20848 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20849 aliased entities to look for the overriden abstract interface
20851 (Is_Interface_Subprogram): Complete documentation.
20852 (Check_Dispatching_Operation): Do not generate code to register the
20853 operation in the dispatch table if the source is compiled with
20854 restriction No_Dispatching_Calls.

20856 No_Return procedure with procedure that is not No_Return
20857 (Check_Dispatching_Call): Suppress the check for an abstract operation
20858 when the original node of an actual is a tag-indeterminate attribute
20859 call, since the attribute, which must be 'Input, can never be abstract.
20860 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20861 call to the Input attribute (even when rewritten).
20862 (Propagate_Tag): Augment comment to indicate the possibility of a call
20863 to an Input attribute.
20865 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20866 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20868 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
20869 No_Wide_Characters is no longer partition-wide
20870 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)

20875 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20877 2006-02-13 Javier Miranda <miranda@adacore.com>
20879 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20880 handles default-initialized components to keep separate the management
20881 of this feature but also avoid the unrequired resolution and
20882 expansion of components that do not have partially initialized
20884 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20885 (Check_Bounds): Likewise.
20886 (Check_Length): Likewise.
20888 2006-02-13 Javier Miranda <miranda@adacore.com>
20889 Ed Schonberg <schonberg@adacore.com>
20891 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20892 abstract interface type call analyze_and_resolve to expand the type
20893 conversion into the corresponding displacement of the
20894 reference to the base of the object.
20895 (Eval_Attribute, case Width): For systems where IEEE extended precision
20896 is supported, the maximum exponent occupies 4 decimal digits.
20897 (Accessibility_Message): Add '\' in 2-line warning message.
20898 (Resolve_Attribute): Likewise.
20899 (case Attribute_Access): Significantly revise checks
20900 for illegal access-to-subprogram Access attributes to properly enforce
20901 the rules of 3.10.2(32/2).
20902 Diagnose use of current instance with an illegal attribute.
20904 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20906 (Enclosing_Generic_Unit): New function to return a node's innermost
20907 enclosing generic declaration node.
20908 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20909 (Type_Access_Level): The accessibility level of anonymous acccess types
20910 associated with discriminants is that of the current instance of the
20911 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20912 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20913 (Kill_Current_Values_For_Entity): New function
20914 (Enter_Name): Change formal type to Entity_Id
20916 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20917 Ed Schonberg <schonberg@adacore.com>
20918 Gary Dismukes <dismukes@adacore.com>
20920 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20921 Analyze_Compilation_Unit.
20922 Detect and warn on redundant with clauses detected in a package spec
20923 and/or body when -gnatwr is used.
20924 (Analyze_Context): Analyze config pragmas before other items
20925 (Install_Context_Items): Don't analyze config pragmas here
20926 (Install_Limited_Withed_Unit): Set limited entity of package in
20927 with_clause so that cross-reference information or warning messages on
20928 unused packages can be properly generated
20929 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20930 has Error_Posted set. Prevent infinite loops in illegal programs.
20931 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20932 to the point of the error test requiring the current unit to be private.
20933 This ensures that private with clauses are not exempted from the basic
20934 checking for being a descendant of the same library unit parent as a
20935 withed private descendant unit.
20936 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20937 handle private with clauses properly, as well as to account for cases
20938 where the withed unit is a public descendant of a private ancestor
20939 (in which case the current unit must be a descendant of the private
20940 ancestor's parent). The spec comments were updated accordingly. Also,
20941 the old error message in this subprogram was replaced with error
20942 messages that mirror the errors tested and reported by
20943 Check_Private_Child_Unit.
20944 Parameter and variable names improved for readability.
20945 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20946 private as the precondition for calling
20947 Check_Private_Limited_Withed_Unit since that subprogram has been
20948 revised to test public units as well as private units.

20953 Javier Miranda <miranda@adacore.com>
20955 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20956 that Scope_Stack.First = 1.
20957 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20958 were not always properly handled previously.
20959 (Formal_Entity): Complete rewrite, to handle properly some complex case
20960 with multiple levels of parametrization by formal packages.
20961 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20962 to the corresponding derived type declaration for proper semantics.
20964 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20965 (Check_Component): Enforce restriction on components of
20966 unchecked_unions: a component in a variant cannot contain tasks or
20968 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20970 Add pragma Ada_2005 (synonym for Ada_05)
20971 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20972 were not always properly handled previously.
20973 Document that pragma Propagate_Exceptions has no effect
20974 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20975 (Set_Convention_From_Pragma): Check that if a convention is
20976 specified for a dispatching operation, then it must be
20977 consistent with the existing convention for the operation.
20978 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20979 longer required to specify an vtable-ptr component in the record. For
20980 compatibility reasons we leave the support for the previous definition.
20981 (Analyze_Pragma, case No_Return): Allow multiple arguments
20983 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20984 non-overrideen inherited operation with a controlling result as
20985 illegal only its implicit declaration comes from the derived type
20986 declaration of its result's type.
20987 (Check_Possible_Deferred_Completion): Relocate the object definition
20988 node of the subtype indication of a deferred constant completion rather
20989 than directly analyzing it. The analysis of the generated subtype will
20990 correctly decorate the GNAT tree.
20991 (Record_Type_Declaration): Check whether this is a declaration for a
20992 limited derived record before analyzing components.
20993 (Analyze_Component_Declaration): Diagnose record types not explicitly
20994 declared limited when a component has a limited type.
20995 (Build_Derived_Record_Type): Code reorganization to check if some of
20996 the inherited subprograms of a tagged type cover interface primitives.
20997 This check was missing in case of a full-type associated with a private
20999 (Constant_Redeclaration): Check that the subtypes of the partial and the
21000 full view of a constrained deferred constant statically match.
21001 (Mentions_T): A reference to the current type in an anonymous access
21002 component declaration must be an entity name.
21003 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21004 class_wide type to refer to full type, not to the incomplete one.
21005 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21006 available. Required to give support to the certified run-time.
21007 (Analyze_Component_Declaration): In case of anonymous access components
21008 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21009 (Process_Discriminants): For an access discriminant, use the
21010 discriminant specification as the associated_node_for_itype, to
21011 simplify accessibility checks.
21013 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21014 Javier Miranda <miranda@adacore.com>
21016 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21017 abstract interpretations on an operator, remove interpretations that
21018 yield Address or a type derived from it, if one of the operands is an
21020 (Try_Object_Operation.Try_Primitive_Operation,
21021 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21022 location when creating the new reference to a primitive or class-wide
21023 operation as a part of rewriting a subprogram call.
21024 (Try_Primitive_Operations): If context requires a function, collect all
21025 interpretations after the first match, because there may be primitive
21026 operations of the same type with the same profile and different return
21027 types. From code reading.
21028 (Try_Primitive_Operation): Use the node kind to choose the proper
21029 operation when a function and a procedure have the same parameter
21031 (Complete_Object_Operation): If formal is an access parameter and prefix
21032 is an object, rewrite as an Access reference, to match signature of
21033 primitive operation.
21034 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21035 by an expanded name with prefix Standard, when the operands are of an
21036 anonymous access type.
21037 (Remove_Abstract_Operations): If the operation is abstract because it is
21038 inherited by a user-defined type derived from Address, remove it as
21039 well from the set of candidate interpretations of an overloaded node.
21040 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21043 2006-02-13 Bob Duff <duff@adacore.com>
21045 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21046 redundant use clauses.
21047 In particular, if the scope of two use clauses overlaps, but one is not
21048 entirely included in the other, we should not warn. This can happen
21049 with nested packages.
21050 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21051 reported errors. The bug was reported when the compiler was built
21052 with assertions enabled.
21053 (Find_Type): If the node is a 'Class reference and the prefix is a
21054 synchronized type without a corresponding record, return the type
21057 2006-02-13 Javier Miranda <miranda@adacore.com>
21059 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21060 if this is the full-declaration associated with a private declaration
21061 that implement interfaces, then the private type declaration must be
21063 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21064 as aliased. The use of the 'access attribute is not available for such
21065 object (for this purpose the object should be explicitly marked as
21066 aliased, but being an anonymous type this is not possible).
21068 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21069 Robert Dewar <dewar@adacore.com>
21071 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21072 compilation unit is an elaboration scope.
21073 (Add_Task_Proc): Add '\' in 2-line warning message.
21074 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21076 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21077 Javier Miranda <miranda@adacore.com>
21079 * sem_type.adb (Write_Overloads): Improve display of candidate
21081 (Add_One_Interp): Do not add to the list of interpretations aliased
21082 entities corresponding with an abstract interface type that is an
21083 immediate ancestor of a tagged type; otherwise we have a dummy
21084 conflict between this entity and the aliased entity.
21085 (Disambiguate): The predefined equality on universal_access is not
21086 usable if there is a user-defined equality with the proper signature,
21087 declared in the same declarative part as the designated type.
21088 (Find_Unique_Type): The universal_access equality operator defined under
21089 AI-230 does not cover pool specific access types.
21090 (Covers): If one of the types is a generic actual subtype, check whether
21091 it matches the partial view of the other type.
21093 2006-02-13 Thomas Quinot <quinot@adacore.com>
21095 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21096 line. This is necessary to allow In_Extended_Main_Unit to provide
21097 correct results for itypes while writing out expanded source.
21098 (Close_File): No need to update the source_index_table here since it's
21099 now done for each line.
21101 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21102 Robert Dewar <dewar@adacore.com>
21104 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21105 preserve the source unit where the itype is declared, and prevent a
21107 (Note_Implicit_Run_Time_Call): New procedure
21108 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21111 * sprint.ads: Document use of $ for implicit run time routine call
21113 2006-02-13 Quentin Ochem <ochem@adacore.com>
21115 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21118 2006-02-13 Bob Duff <duff@adacore.com>
21120 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21121 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21122 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21123 raise Constraint_Error.
21125 * s-vallli.adb (Scan_Long_Long_Integer): Call
21126 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21127 do not scan leading blanks and sign twice.
21128 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21129 raise Constraint_Error.
21131 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21132 Scan_Long_Long_Unsigned): Split out most of the processing from
21133 Scan_Long_Long_Unsigned out into
21134 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21135 This prevents scanning leading blanks and sign twice.
21136 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21139 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21140 out most of the processing from Scan_Unsigned out into
21141 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21142 This prevents scanning leading blanks and sign twice.
21144 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21145 use with Modular'Value attribute.
21146 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21346 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21347 link to the version that does nothing. This way the task termination

21349 because of an unhandled exception.
21351 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21352 handler because of an unhandled exception.
21354 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21360 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21361 non-tasking version of the soft link for task termination. We do
21362 nothing since if we are using the non-tasking version it

21365 in charge of finalizing the global list for controlled objects.
21366 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21367 instead for handling run-time termination in a more flexible way.
21368 (Adafinal_NT): This new procedure will take care of finalizing the
21369 global list for controlled objects if needed, but no tasking
21372 * s-tarest.adb (Task_Lock): Do not try to lock again the
21373 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21374 some run-time operations.
21375 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21376 until all nested locks have been released.
21377 (Task_Wrapper): Call the fall-back task termination handler. It

21380 procedure for the environment task.
21381 (Task_Wrapper): suppress warnings around declaration of

21385 moved to the Common_ATCB record.
21386 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21387 Common_ATCB record.
21388 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21389 Common_ATCB record.
21391 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21392 Fall_Back_Handler, and Specific_Handler.

21395 defined in Ada.Task_Termination, to avoid circular dependencies.
21396 (Termination_Handler): Redefine this type here, alredy defined in
21397 Ada.Task_Termination, for avoiding circular dependencies.
21398 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21399 for storing task termination handlers. In addition,
21400 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21401 Common_ATCB because it is used by both the regular and the restricted
21403 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21404 Common_ATCB because it is used by both the regular and the restricted
21406 (Common_ATCB): Added a dynamic task analyzer field.
21408 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21409 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

21411 tasks but the environment task.
21412 (Finalize_Global_Tasks): Call the task termination procedure for the
21413 environment task. The call to Finalize_Global_List is now performed
21414 using the soft links mechanism.
21415 (Task_Wrapper): added dynamic stack analysis.
21417 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21418 potentially blocking operations has been moved from
21419 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21420 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21421 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21422 this run-time check.
21424 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21425 of task termination procedure.
21426 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21468 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21469 to the specification because the frontend generates code that uses this
21471 (Set_Interface_Table): Add missing assertion.
21472 Update documentation describing the run-time structure.
21473 (Displace): New subprogram that displaces the pointer to the object
21474 to reference one of its secondary dispatch tables.
21475 (IW_Membership): Modified to use the new table of interfaces.
21476 (Inherit_TSD): Modified to use the new table of interfaces.
21477 (Register_Interface_Tag): Use the additional formal to fill the
21478 contents of the new table of interfaces.
21479 (Set_Interface_Table): New subprogram that stores in the TSD the

21494 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21495 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21496 record component containing the tag of the secondary dispatch table we
21497 have to use the Offset_To_Top run-time function to get this information;
21498 otherwise if the pointer to the base of the object has been displace
21499 we get a wrong value if we use the 'position attribute.
21501 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21502 all the calls to Expand_Interface_Thunk.
21503 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21504 interfaces; hence the call to Set_Interface_Table was clearly wrong.

21506 ensure that the interfaces implemented by the ancestors are placed
21507 at the header of the generated list.
21508 (Expand_Interface_Conversion): Handle the case in which the displacement
21509 associated with the interface conversion is not statically known. In
21510 this case we generate a call to the new run-time subprogram Displace.

21512 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21513 Get_Tagged_Kind and Set_Tagged_Kind.

21518 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21519 primary dispatch table for a type.

21521 secondary dispatch table respectively of a tagged type.
21523 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

21535 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21536 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21537 RE_TK_Tagged, RE_TK_Task.
21539 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21540 Init_Secondary_Tags_Internal to allow its use with interface types and
21541 also to generate the code for the new additional actual required
21542 by Set_Offset_To_Top.
21543 (Build_Init_Statements): In case of components associated with abstract
21544 interface types there is no need to generate a call to its IP.
21545 (Freeze_Record_Type): Generate Select Specific Data tables only for
21547 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21548 the bodies and specifications of the predefined primitive operations
21549 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21550 for concurrent types.
21552 * exp_sel.ads, exp_sel.adb: New files.
21554 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21555 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21556 properly protected objects and attach handler in the case of the
21557 restricted profile.
21558 Move embeded package Select_Expansion_Utilities into a separate external

21561 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
21562 (Build_K, Build_S_Assignment): New subprograms, part of the select
21563 expansion utilities.

21566 where the trigger is a dispatching procedure of a limited tagged type.
21568 2005-12-09 Olivier Hainque <hainque@adacore.com>
21570 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21571 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21572 about the use and expansion of SAVE_EXPRs in the various possible
21573 renaming handling cases.
21574 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21575 abusing DECL_FCONTEXT.

21667 * g-diopit.adb (Find): Fix test to exit the iterator and make sure that
21668 the iterator is quitting iteration on parent directory.
21670 2005-12-09 Javier Miranda <miranda@adacore.com>
21672 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21673 and the assignment to a class-wide object, before the assignment we
21674 generate a run-time check to ensure that the tag of the Target is
21675 covered by the tag of the source.
21677 2005-12-09 Robert Dewar <dewar@adacore.com>
21679 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean
21680 parameter in call to Image_Wide_Character.

21694 component associated with the secondary table of an abstract interface
21695 type, return the entity associated with such abstract interface type.
21696 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21697 base type to create anonymous subtype, because entity may be a locally
21698 declared subtype or generic actual.
21699 (Find_Interface): New subprogram that given a tagged type and one of its
21700 component associated with the secondary table of an abstract interface
21701 type, return the entity associated with such abstract interface type.
21703 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21704 conversion cannot be handled at compile time. In this case we pass this
21705 information to the expander to generate the appropriate code.

21740 copied component does not have a known static Esize, then reset
21741 the size and positional fields of the new component.
21742 (Analyze_Component_Declaration): A limited component is
21743 legal within a protected type that implements an interface.
21744 (Collect_Interfaces): Do not add to the list the interfaces that
21745 are implemented by the ancestors.
21746 (Derived_Type_Declaration): If the parent of the full-view is an
21747 interface perform a transformation of the tree to ensure that it has
21748 the same parent than the partial-view. This simplifies the job of the
21749 expander in order to generate the correct object layout, and it is
21750 needed because the list of interfaces of the full-view can be given in
21752 (Process_Full_View): The parent of the full-view does not need to be
21753 a descendant of the parent of the partial view if both parents are
21755 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21756 "limited" the parent must be a limited type.
21757 (Build_Derived_Record_Type): A derived type that is explicitly limited
21758 must have limited ancestor and progenitors.
21759 (Build_Derived_Type): Ditto.

21770 (Process_Full_View): Improve the check for the "no hidden interface"
21771 rule as defined by AI-396.
21773 2005-12-09 Robert Dewar <dewar@adacore.com>
21775 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
21776 types, not on record subtypes.
21777 (Freeze_Entity): Code cleanup. Add barrier to the loop
21778 that generates the references for primitive operations. This allows to
21779 remove an unnecessary exception handler.

21787 sources of the project.
21788 Take into account the new command Check, for gnatcheck. Treat as for

21830 available user-specified stream attributes on limited parameters to
21831 also test the type directly rather than only its underlying type (for
21832 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21833 attributes are visible at the point of the subprogram declaration.
21834 For Ada 2005, the error message is modified to indicate that the
21835 type's stream attributes must be visible (again, only for -gnat05).

21867 types use the corresponding record type. This was not needed before
21868 the implementation of Ada 2005 synchronized types because
21869 concurrent types were never tagged types in Ada 95.

21997 * socket.c: Add extern int h_errno for rtems since networking header
21998 files are not available at this point in a tool bootstrap. Newlib

22002 Roger Sayle <roger@eyesopen.com>
22005 * misc.c (internal_error_function): Don't use vsprintf to format
22006 the error message text, instead use pp_format_text and the new

22017 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
22018 a temporary if taking the address of something that is neither
22019 reference, declaration, or constant, since the gimplifier
22020 can't handle that case.
22022 2005-11-17 Laurent Guerby <laurent@guerby.net>
22025 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22092 * gen-soccon.c: Complete value expansion should not be performed on
22093 TARGET, as it has the form of a math expression, and some components
22094 may be platform-defined macros.
22095 For VxWorks, generate the OK and ERROR values.
22096 New constants giving the sizes of the components of C struct timeval.

22102 * types.ads: Include All_Checks in Suppress_Array
22104 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
22105 not(a=b), since we no longer do this rewriting, and hence it is not
22107 (Elaboration_Checks_Suppressed): Add special casing to
22108 deal with different cases of static and dynamic elaboration checks (all
22109 checks does not count in the first case, but does in the second).
22110 (Expr_Known_Valid): Do not assume that the result of any arbitrary
22111 function call is valid, since this is not the case.
22112 (Ensure_Valid): Do not apply validity check to a real literal
22113 in a universal or fixed context
22115 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22116 elementary types using the operator in standard. It is cleaner not to
22117 modify the programmers intent, especially in the case of floating-point.
22118 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22119 it did not matter because we always rewrote a/=b to not(a=b).
22120 (Expand_Allocator_Expression): For an allocator expression whose nominal
22121 subtype is an unconstrained packed type, convert the expression to its
22122 actual constrained subtype.
22123 Implement warning for <= or >= where < or > not possible
22124 Fix to Vax_Float tests (too early in many routines, causing premature
22125 Vax_Float expansions.
22127 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
22128 to be used with packages and generic packages as well as with
22130 (Suppress): Set All_Checks, but not Elaboration_Check, for case
22131 of pragma Suppress (All_Checks)
22132 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22133 a string literal for precise control over warnings.
22134 Avoid raise of pragma in case of unrecognized pragma and just return
22137 * sem_prag.ads: Minor reformatting
22139 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22140 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
22141 Switch. Do not handle any exception.
22142 Include -gnatwx as part of -gnatg (warn on redundant parens)
22143 Allow optional = after -gnatm
22144 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22145 longer sets Elaboration_Checks.
22146 Code to set warning mode moved to Sem_Warn
22147 so that it can be shared by pragma processing.
22149 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22152 * s-taprop-solaris.adb:
22153 Change some <= to =, to avoid new warning

22161 * exp_vfpt.adb: Handle /= case
22162 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22170 Increase default priority on Lynx from 15 to 17, and meet the Ada
22171 requirement that Default_Priority be ((Priority'First +
22172 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22274 we are not defining the type.
22275 <E_Record_Type>: Likewise.
22276 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22277 to get advantage of the new maybe_stabilize_reference interface, to
22278 ensure that what we reference is indeed stabilized instead of relying
22279 on assumptions on what the stabilizer does.
22280 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22281 type imported through a limited_with clause, use its non-limited view.
22282 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22284 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22285 of #if sections + explicit comparisons of convention identifiers.

22287 before early-returning for certain types when code generation is
22289 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22290 nullification of gnu_expr we do for objects with address clause and
22291 that we are not defining.
22292 (elaborate_expression_1): Do not create constants when creating
22293 variables needed by the debug info: the dwarf2 writer considers that
22294 CONST_DECLs is used only to represent enumeration constants, and emits
22296 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22297 object with an address clause into an indirect reference, drop the
22298 initializing expression.
22300 (STACK_CHECK_BUILTIN): Delete.
22301 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22310 subtype to build an actual type with bounds template.
22311 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22312 is provided by the front-end, use that subtype to compute the size of
22313 the deallocated object.

22320 maybe_stabilize, for common uses without restriction on lvalues and
22321 without need to check for the success indication.
22322 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22323 pass false instead of 0 as the FORCE argument which is a bool.
22324 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22325 attached to a renaming pointer has been properly stabilized, as no such
22326 object is attached otherwise.
22327 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22328 function uses the "target pointer" return mechanism.
22329 Reinstate conversion of the actual to the type of the formal
22330 parameter before any other specific treatment based on the passing
22331 mechanism. This turns out to be necessary in order for PLACEHOLDER
22332 substitution to work properly when the latter type is unconstrained.

22336 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22337 with extra arguments to control whether to recurse through non-values
22338 and to let the caller know if the stabilization has succeeded.
22340 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22341 static output of record constructor if all the components are constant.
22342 (gnat_build_constructor): For a record type, sort the list of field
22343 initializers in increasing bit position order.
22344 Factor common code to build a storage type for an unconstrained object
22345 from a fat or thin pointer type and a constrained object type.
22346 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22347 types variants, and process special cases of VIEW_CONVERT expressions
22348 as their NOP_EXPR counterpart to ensure we get to the
22349 CORRESPONDING_VARs associated with CONST_DECls.
22350 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22351 on the right-hand side.
22353 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22356 are converting back to its original type.
22357 (convert) <JM input>: Fallthrough regular conversion code instead of
22358 extracting the object if converting to a type variant.
22359 (create_var_decl): When a variable has an initializer requiring code
22360 generation and we are at the top level, check for a potential violation
22361 of a No_Elaboration_Code restriction.
22362 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22363 SIZE and SIZE_UNIT which we need for later back-annotations.

22366 is an unchecked union.
22367 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22368 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22369 main variant, just replace the VIEW_CONVERT_EXPR.

22505 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22506 for task component, in the case of a limited aggregate. The enclosed

22544 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22545 and related): For a prefix that is an explicit dereference of an
22546 access to unconstrained packed array type, annotate the dereference
22547 with an actual subtype so GIGI can make a correct size computation.
22548 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22549 'Unrestricted_Access, if the designated type is an interface we
22550 add a type conversion to force the displacement of the pointer
22551 to the secondary dispatch table.
22552 Use Universal_Real instead of Long_Long_Float when we need a high
22553 precision float type for the generated code (prevents gratuitous
22554 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22555 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22556 'Terminated for task interface class-wide objects. Generate a call to
22557 the predefined dispatching routine used to retrieve the _task_id from
22558 a task corresponding record.

22582 (Expand_N_If_Statement): When killing a dead then-branch in an
22583 if-statement that has elsif_parts, recompute the Current_Value node
22584 for any entity whose value is known from the condition of the first
22586 (Expand_N_Return_Statement): When returning a mutable record, convert
22587 the return value into its actual subtype in order to help the backend
22588 to return the actual size instead of the maximum. This is another
22589 aftermath of not returning mutable records on the sec-stack anymore.
22591 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22592 handling of error msg for suspicious reverse range iteration.

22608 a process handle, not need to convert.
22609 (__gnat_kill) [*]: Add dummy parameter close to match the Win32 spec.
22611 * g-expect.adb: (Kill): Document the new close parameter.
22612 (Close): Do not release the process handle in the kill there as

22614 (Send_Signal): Release the process handle.
22616 2005-11-14 Robert Dewar <dewar@adacore.com>
22618 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22620 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
22623 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

22920 leave it more clear.
22921 (Analyze_Type_Declaration): If type has previous incomplete tagged

22978 whose default is abstract because the object type itself is abstract.
22979 (Find_Type): If the type is incomplete and appears as the prefix of a
22980 'Class reference, it is tagged, and its list of primitive operations
22981 must be initialized properly.
22982 (Chain_Use_Clauses): When chaining the use clauses that appear in the

23011 statement to inhibit warning.
23012 (Resolve_Unary_Op): Do not produce a warning when
23013 processing an expression of the form -(A mod B)
23014 Use Universal_Real instead of Long_Long_Float when we need a high

23857 of constants that is consistent with the contents of g-soccon.ads.
23858 This change also makes gen-soccon self-contained (removing dependencies
23859 upon GCC internal headers).
23861 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
23863 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
23865 * socket.c: Minor reformatting.

23997 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23998 from object notation, the original node is unanalyzed and carries no
23999 semantic information, so that accessiblity checks must be performed on
24000 the type of the actual itself.

24056 position set is provided, we compute one in order to reduce the maximum
24057 length of the keys. This computation first selects a character
24058 position between 1 and the minimum length of the keys in order to
24059 avoid reducing one of the keys to an empty string.
24060 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24061 does not converge. The initialization procedure now comes with a
24062 maximum number of iterations such that when exceeded, an exception is
24063 raised in Compute. The user can initialize this ratio to another value

24069 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24070 that given an entity T creates and returns an Itype that duplicates the
24071 contents of T. The returned Itype has the null-exclusion
24072 attribute set to True, and its Etype attribute references T
24073 to keep the association between the two entities.

24169 Preset_Names for Name_Disp_Asynchronous_Select,
24170 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,

24172 New pragma Debug_Policy
24174 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24176 Switch -gnata also sets Debug_Pragmas_Enabled
24178 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24179 handle an explicit -gnata when compiling predefined files.
24181 2005-09-01 Vincent Celier <celier@adacore.com>
24183 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24184 directories of projects that have no Ada sources.
24186 2005-09-01 Robert Dewar <dewar@adacore.com>
24188 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24189 (makes a difference for wide characters)

24192 Add Wide_Char_Byte_Count feature to count chars vs bytes
24194 2005-09-01 Thomas Quinot <quinot@adacore.com>
24195 Ed Schonberg <schonberg@adacore.com>
24196 Robert Dewar <dewar@adacore.com>
24198 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24199 'Address attribute reference with an overloaded prefix, use the
24200 location of the prefix (not the location of the attribute reference) as
24201 the error location.
24202 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24203 a function renaming thereof, is a valid prefix for 'Size (where it is
24204 intepreted as a function call).
24205 (Statically_Denotes_Entity): New predicate to determine whether the
24206 prefix of an array attribute can be considered static.
24209 (Eval_Attr): Fix failure to evaluate Component_Size for

24220 Ed Schonberg <schonberg@adacore.com>
24222 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24223 become local to the whole package.
24224 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24225 the package was already analyzed the new algorithm "replaces" the
24226 real entities by the shadow ones. This is required to ensure that
24227 the order of these entities in the homonym chains does not change;
24228 otherwise we can have undefined references at linking time because
24229 in case of conflicts the external name of the entities will have
24230 a suffix that depends on the order of the entities in the chain.
24231 (Remove_Limited_With_Clause): Complementary code that completes the
24232 new algorithm and replaces the shadow entities by the real ones.
24233 (Install_Limited_Withed_Unit): When unchaining entities before the
24234 installation of the shadow entities, only regular entities of the
24235 public part must be taken into account. This is required to
24236 keep this routine in synch with the work done by Remove_Limited_
24238 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24239 even if unit is analyzed, because the analysis of the unit is
24240 idempotent in any case, and the limited view of the unit may have to
24241 be installed for proper visibility.
24242 (Expand_Limited_With_Clause): Even if the unit in the implicit
24243 with_clause has been analyzed already, a limited view of the package
24244 must be built for the current context, if it does not exist yet.

24247 Javier Miranda <miranda@adacore.com>
24248 Gary Dismukes <dismukes@adacore.com>
24250 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24251 defining entity for the instance body, make a new defining identifier
24252 rather than copying the entity of the spec, to prevent accidental
24253 sharing of the entity list.
24254 (Check_Private_View): When exchanging views of private types, build the
24255 list of exchanged views as a stack, to ensure that on exit the exchanges
24256 are undone in the proper order.
24257 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24258 Restore the compilation environment in case of instantiation_error.
24259 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24260 for an anonymous access result.
24261 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24262 (Formal_Entity): Handle properly the case of a formal package that
24263 denotes a generic package renaming.
24265 2005-09-01 Thomas Quinot <quinot@adacore.com>
24267 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24268 clause if the array aggregate is surrounded by parentheses.

24271 Gary Dismukes <dismukes@adacore.com>
24272 Ed Schonberg <schonberg@adacore.com>
24273 Javier Miranda <miranda@adacore.com>
24275 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24277 to check if a type is Constrained in cases related to code generation
24278 (rather than semantic checking) since otherwise we do not generate
24279 similar code for mutable private types depending if their
24280 discriminants are visible or not.
24281 (Check_Abstract_Overriding): Do not complain about failure to override
24282 the primitive operations used in dispatching selects since they will
24283 always be overriden at the freeze point of the type.
24284 (Access_Definition): Separate out handling for resetting the scope
24285 of an anonymous access function result type. Retrieve the scope
24286 of the associated function rather than using Current_Scope, which
24287 does not have a consistent value (depends on whether we're in the
24288 middle of analyzing formal parameters). Add ??? comment about
24289 finding a cleaner way to handle the special cases of scope setting.
24290 (Process_Incomplete_Dependents): A protected operation is never a
24291 dispatching operation (only its wrapper may be).
24292 (Build_Derived_Record_Type): In case of tagged private types that
24293 implement interfaces add derivation of predefined primitive
24295 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24296 by two parameters that are used in case of derivation from abstract
24297 interface types: No_Predefined_Prims is used to avoid the derivation
24298 of predefined primitives from the interface, and Predefined
24299 Prims_Only is used to complete the derivation predefined primitives
24300 in case of private tagged types implementing interfaces.
24301 Fix typo in comments
24302 (Find_Interface_In_Descendant): Protect the frontend against
24303 wrong code with large circularity chains.
24304 (Is_Private_Overriding): Add support for entities overriding interface
24305 subprograms. The test failed because Entities associated with overriden
24306 interface subprograms are always marked as hidden (and used to build
24307 the secondary dispatch table); in this case the overriden entity is
24308 available through the field abstract_interface_alias (cf. override_
24309 dispatching_operation)
24310 (Access_Definition): Set the scope of the type to Current_Scope for the
24311 case of a function with an anonymous access result type.
24312 (Access_Subprogram_Declaration): Handle creation of the type entity for
24313 an access-to-function type with an anonymous access result.
24314 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24315 in handling for N_Access_Function_Definition.
24316 (Analyze_Subtype_Declaration): Modify the text of error message.
24317 (Derived_Type_Declaration): Modify the text of error message.
24318 (Process_Subtype): Modify the text of error message plus cleanup
24319 of one redundant error message.
24320 (Analyze_Component_Declaration): Code cleanup.
24321 (Analyze_Object_Declaration): Code cleanup.
24322 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24323 attribute in case of access types. Code cleanup.
24324 (Array_Type_Declaration): Code cleanup.
24325 (Process_Discriminants): Create the new null-excluding itype
24326 if required. Code cleanup.
24327 (Process_Subtype): Create the new null-excluding itype if
24328 required. Code cleanup.
24329 (Build_Derived_Record_Type): Code cleanup to avoid calling
24330 twice the subprogram derive_subprograms in case of private
24331 types that implement interfaces. In this particular case the
24332 subprogram Complete_Subprograms_Derivation already does the
24333 job associated with the second call.
24335 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24336 conversion to the full view when generating an operation for a
24337 discriminant whose type may currently be private.
24339 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24340 Javier Miranda <miranda@adacore.com>
24342 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24343 V (Obj.F), the rewriting does not involve the indexed component, but
24344 only the selected component itself.
24345 Do not apply the transformation if the analyzed node is an actual of a
24346 call to another subprogram.
24347 (Complete_Object_Operation): Retain the entity of the
24348 dispatching operation in the selector of the rewritten node. The
24349 entity will be used in the expansion of dispatching selects.
24350 (Analyze_One_Call): Improve location of the error message associated
24352 (Analyze_Selected_Component): No need to resolve prefix when it is a
24353 function call, resolution is done when parent node is resolved, as
24355 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24356 when attempting to resolve a call transformed from its object notation.
24357 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24358 of the argument list for each interpretation of the operation.
24359 (Try_Object_Operation): The designated type of an access parameter may
24360 be an incomplete type obtained through a limited_with clause, in which
24361 case the primitive operations of the type are retrieved from its full
24363 (Analyze_Call): If this is an indirect call, and the return type of the
24364 access_to_subprogram is incomplete, use its full view if available.
24366 2005-09-01 Javier Miranda <miranda@adacore.com>
24367 Gary Dismukes <dismukes@adacore.com>
24369 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24370 access types the null-exclusion and access-to-constant attributes must
24372 (Analyze_Return_Statement): When the result type is an anonymous access
24373 type, apply a conversion of the return expression to the access type
24374 to ensure that appropriate accessibility checks are performed.
24375 (Analyze_Return_Type): For the case of an anonymous access result type,
24376 generate the Itype and set Is_Local_Anonymous_Access on the type.
24377 Add ??? placeholder for check to disallow returning a limited object
24378 in Ada 2005 unless it's an aggregate or a result of a function call.
24379 Change calls from Subtype_Mark to Result_Definition.
24380 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24381 Result_Definition in call to Make_Function_Specification.
24382 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24383 Set_Result_Definition.
24384 (Make_Inequality_Operator): Change formal Subtype_Mark to
24385 Result_Definition in call to Make_Function_Specification.
24386 (Process_Formals): Create the new null-excluding itype if required.
24387 (New_Overloaded_Entity): For an entity overriding an interface primitive
24388 check if the entity also covers other abstract subprograms in the same
24389 scope. This is required to handle the general case, that is, overriding
24390 other interface primitives and overriding abstract subprograms inherited
24391 from some abstract ancestor type.
24392 (New_Overloaded_Entity): For an overriding entity that comes from
24393 source, note the operation that it overrides.
24394 (Check_Conformance, Type_Conformant): Addition of one new formal
24395 to skip controlling formals in the analysis. This is used to
24396 handle overloading of abstract interfaces.
24397 (Base_Types_Match): Add missing case for types imported from
24398 limited-with clauses
24399 (New_Overloaded_Entity): Add barrier to protect the use of
24400 the "alias" attribute.
24402 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24404 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24405 verify that the procedure and the entry are mode conformant.
24406 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24407 as a different operator, which is often a cut-and-paste error.
24409 2005-09-01 Javier Miranda <miranda@adacore.com>
24410 Ed Schonberg <schonberg@adacore.com>
24412 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24413 used in controlling parameters exclude null because it is necessary to
24414 read the tag to dispatch, and null has no tag.
24415 (Override_Dispatching_Operation): If the previous operation is inherited
24416 from an interface, it becomes hidden and does not participate in later
24419 2005-09-01 Javier Miranda <miranda@adacore.com>
24420 Ed Schonberg <schonberg@adacore.com>
24421 Gary Dismukes <dismukes@adacore.com>
24423 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24424 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24425 the expander will generate the corresponding run-time check to evaluate
24427 (Resolve_Call): Check for legal type of procedure name or prefix that
24428 appears as a trigger in a triggering alternative.
24429 (Valid_Conversion): If expression is ambiguous and the context involves
24430 an extension of System, remove System.Address interpretations.
24431 (Resolve_Qualified_Expression): Reject the case of a specific-type
24432 qualification applied to a class-wide argument. Enhance comment
24433 to explain checking of Original_Node.
24434 (Resolve_Type_Conversion): The location of the error message was not
24435 general enough to handle the general case and hence it has been removed.
24436 In addition, this patch improves the text of the message.
24437 (Resolve_Type_Conversion): Add missing support for access to interface
24439 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24440 do not expand if the expression is the actual in a call, because proper
24441 expansion will take place when the call itself is expanded.
24442 (Resolve_Allocator): If the context is an unchecked conversion, the
24443 allocator inherits its storage pool, if any, from the target type of
24446 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24447 Javier Miranda <miranda@adacore.com>
24449 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24450 inherited interface operation that has an implementation, use the
24451 implementation to avoid spurious ambiguities.
24452 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24453 use the Corresponding_Record_Typ attribute to look for the interface
24454 because it is set by the expander (and hence it is not always
24455 available). For this reason we traverse the list of interfaces
24456 (available in the parent of the concurrent type).
24457 (Interface_Present_In_Ancestor): Handle entities from the limited view
24459 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24461 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24462 from the list of required components.
24463 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24464 primitive procedure of a limited interface with a controlling first
24466 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24468 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24469 capture if it is generated in the second operand of a short-circuit
24471 Do not capture values for variables with address clauses.
24472 (Is_Object_Reference): Treat a function call as an object reference only
24473 if its type is not Standard_Void_Type.
24475 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24477 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24478 to a variable that is statically known to be constant.

24492 Add documentation on environment variable syntax for Expand_Path
24494 * gnat_ugn.texi: Update documentation to include mention of -m switches
24495 Document new treatment of wide characters in max line length
24497 Remove -gnatL/-gnatZ switches, no longer used.
24498 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24501 * gnat_rm.texi: Add doc for two argument form of pragma
24502 Float_Representation.
24503 Add documentation for pragma No_Strict_Aliasing

25260 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25261 longer protected objects. They have been replaced by lower-level
25262 suspension objects made up by a mutex and a condition variable (or
25263 their equivalent given a particular OS) plus some internal data to
25264 reflect the state of the suspension object.
25265 (Initialize, Finalize): Add this initialization procedure for
25266 Suspension_Object, which is a controlled type.
25267 (Finalize): Add the finalization procedure for Suspension_Object,
25268 which is a controlled type.
25270 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25271 Ada.Synchronous_Task_Control because there is no longer a need for a
25272 VxWorks specific version of this package. Target dependencies
25273 has been moved to System.Task_Primitives.Operations.
25275 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25277 (InitializeCriticalSection, EnterCriticalSection,
25278 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25279 pCriticalSection by an anonymous access type so that we avoid problems
25280 of accessibility to local objects.

25287 set the environment task mask here.
25288 (Current_State): Add this function that returns the state of the
25290 (Set_False): Add this procedure that sets the state of the suspension
25292 (Set_True): Add this procedure that sets the state of the suspension
25293 object to True, releasing the task that was suspended, if any.
25294 (Suspend_Until_True): Add this procedure that blocks the calling task
25295 until the state of the object is True. Program_Error is raised if
25296 another task is already waiting on that suspension object.
25297 (Initialize): Add this procedure for initializing the suspension
25298 object. It initializes the mutex and the condition variable which are
25299 used for synchronization and queuing, and it sets the internal state
25301 (Finalize): Add this procedure for finalizing the suspension object,
25302 destroying the mutex and the condition variable.

25307 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25308 which provides a low-level abstraction (using operating system
25309 primitives) for Ada.Synchronous_Task_Control.
25310 This object is made up by a mutex (for ensuring mutual exclusion), a
25311 condition variable (for queuing threads until the condition is
25312 signaled), a Boolean (State) indicating whether the object is open,
25313 and a Boolean (Waiting) reflecting whether there is a task already
25314 suspended on this object.

25331 System.Parameters.No_Abort is True.
25333 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
25334 is no longer done in the body of s-taprop

25579 type derivation of private tagged types implementing interfaces.
25580 In this case some interface primitives may have been overriden

25670 * i-cpp.ads, i-cpp.adb:
25671 This package has been left available for compatibility with previous
25672 versions of the frontend. As part of the new layout this is now a
25673 dummy package that uses declarations available at a-tags.ads
25675 * par-ch3.adb (P_Identifier_Declarations): Give an error for use of

25726 access to subprograms must be recursive.
25727 (Is_Unchecked_Conversion): Improve the test that recognizes
25728 instantiations of Unchecked_Conversion, and allows them in bodies that
25729 are to be inlined by the front-end. When the body comes from an

25754 the case where the discriminant belongs to a nonlimited type, since
25755 such discriminants have their accessibility level defined in the same
25756 way as a normal component of an anonymous access type.
25757 (Resolve_Allocator): When an allocator's designated type is a class-wide
25758 type, check that the accessibility level of type given in the
25759 allocator's expression or subtype indication is not statically deeper

25779 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25780 check on possible violation of restriction No_Direct_Boolean_Operators

26084 the "simple_choice" member in a variant record, in accordance with the
26085 description in the package spec: the information output for a constant
26086 should be "S number", not "SS number".
26087 (Get_Encoded_Name): Return at once if not generating code. Avoids name

26787 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26790 error messages if expansion has been disabled due to previous
26791 (unrelated) errors).
26793 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26794 is disabled, the entity denoted by the argument is the access type
26795 itself, not an underlying record type, so there is no need to go back
26796 to the Corresponding_Remote_Type.

26806 denotes a type in the class.
26807 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26808 of Name_Generic_Dispatching_Constructor.
26810 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26825 the case of renaming of stream attributes when the renaming denotes a
26826 generic formal subprogram association for an abstract formal subprogram.
26827 Check that the attribute is a primitive stream attribute (and not
26828 a class-wide stream attribute) and then rewrite the attribute name
26829 as the name of the appropriate compiler-generated stream primitive.

26833 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26841 itype whose parent is controlled and not yet frozen, do not create a
26842 freeze node for the itype if expansion is disabled.
26844 2005-03-29 Vincent Celier <celier@adacore.com>
26846 * make.adb (Gnatmake): Don't fail if the main project file is declared
26847 as having no Ada sources. Do not display message "no sources to

27502 * a-stunau.ads, a-stunau.adb:
27503 Change interface to allow efficient (and correct) implementation

27549 Update documentation on Must_Be_Byte_Aligned for new spec
27551 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27552 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27553 uses of the Access_Disp_Table attribute to reference the first dispatch
27554 table associated with a tagged type. As
27555 part of the implementation of abstract interface types,
27556 Access_Disp_Table has been redefined to contain a list of dispatch
27557 tables (rather than a single dispatch table).
27558 Similarly, upgrade all the references to Tag_Component by the
27559 new attribute First_Tag_Component.
27560 (Find_Inherited_TSS): Moved to exp_tss.

27568 Bit packed array ops are only called if operands are known to be
27570 (Component_Equality): When returning an N_Raise_Program_Error statement,
27571 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27572 expects that only expressions have a bona fide type).
27573 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27574 determine the amount of data to be copied.
27576 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27577 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27604 (Task_Body_Procedure): Removed.
27605 (Set_Task_Body_Procedure): Removed.
27606 These subprogram have been removed because the attribute
27607 Task_Body_Procedure has been moved to the corresponding task type
27608 or task subtype entity to leave a field free to store the list
27609 of interfaces implemented by a task (for AI-345)
27610 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27611 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27612 expression flag Do_Range_Check

27628 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27629 attribute Task_Body_Procedure rather than the old semantic field that
27630 was available in the task_type_declaration node.
27632 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27633 interface type definitions.
27634 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27637 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a

27674 expression to the type of the object when the object is constant.
27675 Reverse defer_debug_incomplete_list before traversing it, so that trees
27676 are processed in the order at which they were added to the list. This
27677 order is important when using the stabs debug format.
27678 If we are deferring the output of debug information, also defer this
27679 output for a function return type.
27680 When adding fields to a record, prevent emitting debug information
27681 for incomplete records, emit the information only when the record is
27683 (components_to_record): New parameter defer_debug.

27691 unconstrained arrays properly.
27693 * gigi.h (write_record_type_debug_info): New function.
27694 Convert to use ANSI-style prototypes. Remove unused
27695 declarations for emit_stack_check, elab_all_gnat and

27720 Expansion_Delayed and handle case when it's inside an
27721 N_Qualified_Expression.
27723 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27724 Comes_From_Generic, to recognize accurately that the parent type in a
27725 derived type declaration can be traced back to a formal type, because
27726 it is one or is derived from one, or because its completion is derived
27728 (Constrain_Component_Type): If component comes from source and has no
27729 explicit constraint, no need to constrain in in a subtype of the
27731 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27732 Minor change to propagate Is_Ada_2005 flag

27736 (assoc_to_constructor): Ignore fields that have a
27737 Corresponding_Discriminant.

27739 function returns "by target", dereference the target pointer using the
27740 type of the actual return value.
27741 <all>: Be prepared for a null gnu_result.
27742 (processed_inline_subprograms): Check flag_really_no_inline

27755 System.Pack_nn unit.
27757 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27759 Needed now that we do some processing for IN parameters as well. This
27760 may well fix some unrelated errors.
27761 (Expand_Call): Handle case of unaligned objects (in particular those
27762 that come from packed arrays).
27763 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27764 renamed entity is an inherited operation, re-expand the call using the
27765 original operation, which is the one to call.
27766 Detect attempt to inline parameterless recursive subprogram.
27767 (Represented_As_Scalar): Fix to work properly with private types
27768 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27769 accurate estimate. Yields True in far fewer cases than before,
27770 improving the quality of code that depends on this test.
27772 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27773 over both visible and private declarations to remove them from tree,
27774 and mark subprograms declared in package as eliminated, to prevent
27775 spurious use in subsequent compilation of generic units in the context.
27777 * exp_util.ads: Minor cleanup in variable names
27779 * sem_eval.ads, sem_eval.adb: Minor reformatting

27786 of an initialization call.
27788 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27790 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27791 that appears in the instantiation rather than the internal subtype
27792 generated in the wrapper package, to avoid anomalies in gigi when the
27793 target is derived from a private type whose full view is an access type.
27795 2005-03-15 Robert Dewar <dewar@adacore.com>
27797 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,

27805 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27806 here from exp_attr so it can be shared between exp_attr and exp_dist.
27807 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27808 all TSS names, not a subset thereof, and the previous name introduced
27809 an unnecessarily confusion that a distinction might exist between
27810 "OK" TSS names and some "not OK" TSS names.
27812 2005-03-15 Doug Rupp <rupp@adacore.com>
27814 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27817 2005-03-15 Pascal Obry <obry@adacore.com>
27818 Eric Botcazou <ebotcazou@adacore.com>
27822 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27823 when IN_RTS. This is to work around a bootstrap path problem.
27825 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27826 table and pass it to __gnat_install_SEH_handler().
27827 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.

27833 Vincent Celier <celier@adacore.com>
27834 Arnaud Charlet <charlet@adacore.com>
27837 This change works fine when gnatlib is built from the gcc directory,
27838 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27839 is not passed to ada/Makefile.in, so more work is needed by a
27840 Makefile/configure expert.
27842 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27843 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27844 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27846 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27847 Run ranlib on libgccprefix.a
27848 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27849 (ADA_INCLUDE_SRCS): Split Ada packages.
27851 2005-03-15 Robert Dewar <dewar@adacore.com>
27853 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27855 * impunit.adb: Add GNAT.UTF_32
27857 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27859 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27860 now uses GNAT.UTF_32).
27862 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27863 capabilities for categorizing characters using Unicode categories
27865 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27867 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27868 instantiation that has been rewritten as a package body, retrieve spec
27869 to generate proper name for implicit_with_clause.
27870 (Install_Parents): Recognize a parent that is an instantiation but has
27871 been rewritten as a package declaration during analysis.
27873 2005-03-15 Javier Miranda <miranda@adacore.com>
27874 Ed Schonberg <schonberg@adacore.com>
27876 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27877 parameter reported some error we immediately return. This improves the
27878 behaviour of the frontend in case of errors.
27879 (Install_Parent, Remove_Parent): Introduce new flag
27880 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27881 ancestor of a generic child unit, when the child is being instantiated.
27882 (Inline_Instance_Body): If we are compiling the private
27883 part or the body of a child unit, restore the proper visibility of the
27884 parents after compiling the instance body.
27886 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27887 Javier Miranda <miranda@adacore.com>
27890 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27891 of a private type, in which case it is underlying_type that denotes
27892 the proper task. Also modified to use the new entity attribute
27893 that is directly available in the task type and task subtype entities
27894 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27895 arrays when other dimensions than the first are constrained by
27896 discriminants of an enclosing record.
27897 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27898 a combination of indexed and selected components, find ultimate entity
27899 and generate the appropriate reference for it, to suppress spurious
27901 (Note_Possible_Modification): If an entity name has no entity, return.
27902 (Is_Variable): A function call never denotes a variable.
27903 (Requires_Transient_Scope): For record types, recurse only on
27904 components, not on internal subtypes that may have been generated for
27905 constrained components.
27907 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27909 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27910 Eliminated as candidates for resolution. Both efficient, and avoids
27911 anomalies with operators declared in deleted code.
27912 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27913 expansion is disabled (as when compiling a generic) to prevent spurious
27914 warnings on prefixes of selected components.
27916 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27918 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27919 attached to a list before checking whether it appears in the private
27920 declarations of the current package.
27921 (Make_Inequality_Operator): Insert declaration in proper declarative
27922 list rather than just setting the Parent field, so that
27923 Is_Private_Declaration can handle it properly.
27925 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27927 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27928 a renaming a body, check that the renamed subprogram in not intrinsic.
27929 (Find_Direct_Name): If several use_visible entities hide
27930 each other, and the context is a predefined file compiled through
27931 rtsfind, keep only the entity that comes from a predefined file.
27933 2005-03-15 Geert Bosch <bosch@adacore.com>
27935 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27936 long float padding to also cover AMD64 and IA64.
27938 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27940 * s-imgwch.adb: Add with and use of Interfaces.

28322 (Unit_Declaration_Node): Ditto.
28323 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28324 has a packed array type, the prefix has been rewritten into a type

28330 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28331 Remove ["0A"] from comment, since it can look like a line terminator.
28332 Currently we don't permit this, but this is under discussion by the
28333 ARG, and it is easy enough to use a different example.
28335 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28336 handling UTF-32 encoding for wide wide character.

28355 wrong null-exclusion value by a warning message.
28356 (Enable_Range_Check): Do range check if the prefix is an

28376 defined for subprogram renaming declarations. When set, the field
28377 indicates the defining entity of a corresponding formal subprogram
28378 when the renaming corresponds to a formal subprogram association in an
28380 (Set_Corresponding_Formal_Spec): New procedure to return
28381 Corresponding_Formal_Spec field.

28394 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28395 describing the new layout.
28396 (Dispatch_Table): The expander computes the actual array size, allocates
28397 the Dispatch_Table record accordingly, and generates code that displaces
28398 the base of the record after the Typeinfo_Ptr component. The access to
28399 these components is done by means of local functions.
28400 (Offset_To_Top): New function.
28401 (Typeinfo_Ptr): New function.
28402 (Get_TSD): Modified to access the new position of the TSD.

28416 dispatching, setting the controlling status of the formal parameters
28417 and result, and issuing an error if there is no controlling type for
28418 the formal subprogram.
28419 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28420 which is an unclean use of that field, we set the new field
28421 Corresponding_Formal_Spec to make the formal subprogram available to

28429 abstract formal subprograms in error check for functions returning
28430 abstract types. Set scope of new designator for
28431 a parameterless subprogram, so that it is available when checking the
28432 body for nested subprograms, before full analysis of said body.
28433 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28434 subprogram only if inner one comes from source.
28435 (Analyze_Function_Call): If the call is given in object notation, the
28436 analysis of the name rewrites the node and analyzes it with the proper
28437 argument list. After analyzing the name, if the call has been rewritten
28438 and the result type is set, no further analysis is needed.
28439 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28440 mark in function specification, in a context where the formals are
28441 visible and hide outer homographs.
28443 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28444 as the tagged type for the cases of abstract formal subprograms and
28445 renamings of those. Clean up spec comments.
28446 (Check_Dispatching_Context): Add error message to indicate "abstract
28447 procedure", covering the case of a call to a formal abstract procedure
28448 that has statically tagged operands.
28449 (Check_Dispatching_Call): Check for the case of an actual given by
28450 a tag-indeterminate function call whose type is an ancestor of the
28451 containing call's associated tagged type. This situation can occur
28452 for inherited primitives with function defaults. In this case we
28453 use the tagged type's tag directly as the controlling argument for
28455 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28457 * sprint.adb (Sprint_Node_Actual): Split
28458 N_Formal_Subprogram_Declaration into two alternatives for the new

28534 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28535 on the field if Pragma Component_Alignment (Storage_Unit).
28536 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28537 side-effects as if it were a constant; also make SAVE_EXPR to protect

28557 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28558 component of an array of arrays in an assignment context, and the
28559 aggregate has component associations that require sliding on
28560 assignment, force reanalysis of the aggregate to generate a temporary
28561 before the assignment.
28562 (Must_Slide): Make global to the package, for use in Gen_Assign.
28564 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28566 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28567 unchecked union with no inferable discriminants, return a
28568 Raise_Program_Error node, rather than inserting it at the point the
28570 (Expand_Record_Equality, Component_Equality): Handle properly the case
28571 where some subcomponent is an unchecked union whose generated equality
28572 code raises program error.

28580 Arnaud Charlet <charlet@adacore.com>
28582 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28583 address of the exception registration. The Win32 version of this
28584 routine calls __gnat_install_SEH_handler() to initialize the SEH
28585 (Structured Exception Handling) handler.
28586 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28587 SEH (Structured Exception Handling) now.
28588 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28589 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28590 preprocessor condition protecting the call to the extra eh setup
28591 subprogram, which is only available for the ppc target.

28602 for the SEH (Structured Exception Handling) support.
28604 * raise.h: (__gnat_install_SEH_handler): New prototype.
28605 Update copyright notice.
28607 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28637 2005-02-09 Vincent Celier <celier@adacore.com>
28639 * prj-makr.adb (Process_Directory): Put file name in canonical case
28640 before matching against the patterns.
28641 If gnatname has been invoked as <prefix>-gnatname
28642 then invoke the compiler as <prefix>-gcc, not just "gcc".
28644 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28646 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28647 with expansion disabled. The actual subtype is needed among other
28648 places when the selected component appears in the context of a loop
28649 bound, and denotes a packed array.
28650 (Operator_Check): Always use the first subtype in the
28651 error message, to avoid the appearance of internal base types.
28652 (Transform_Object_Operation): Copy each actual in full
28653 to the parameter associations of the constructed call, rather than
28654 using the shallow copy mechanism of New_Copy_List. This ensures that
28655 the chaining of named associations is done properly.
28656 (Complete_Object_Operation): Rewrite node, rather than
28657 replacing it, so that we can trace back to the original selected
28660 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28661 and calls that use object notation, if the called function is not
28662 declared in a withed unit, place the elaboration constraint on the
28663 unit in the context that makes the function accessible.
28664 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28665 imposes an elaboration constraint between two packages.
28667 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28669 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28670 views of a private type after handling its private dependents, to
28671 maintain proper stack discipline between entry and exit from the

28692 Slight fix to documentation of -gnaty with no parameters
28694 * xr_tabls.ads: Add ??? comment for missing overall comment
28696 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28697 we now use by default.
28699 * xsnames.adb: Adjust end of file test to look for five space followed
28700 by '#' instead of six spaces. The format of xsnames.adb was modified
28701 in the last update.
28703 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28706 * clean.adb: Minor reformatting.
28708 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28709 gnatname.adb: Minor reformatting
28710 Add 2005 to copyright output when utility is run
28712 * csets.adb: Eliminate obsolete comment
28714 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28717 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28719 2005-02-09 Sergey Rybin <rybin@adacore.com>
28721 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28722 the difference between compact and incompact layout and add the record
28723 representation clause to the example illustrating different layouts.
28724 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28725 component clauses").
28727 2005-02-09 Florian Villoing <villoing@adacore.com>
28729 * gnat_ugn.texi: Fix typos.
28730 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28732 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28733 in the generated documentation.

28772 Use a pragma Elaborate_Body in the spec file instead.
28773 Noticed by code reading.
28775 2005-02-09 Thomas Quinot <quinot@adacore.com>
28777 * exp_util.ads: Minor correction in comment.
28779 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28781 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28782 since this procedure is now too complex to be worth inlining.

29032 is to check if two function signatures for a call-site and a callee are
29033 compatible enough for the call to be valid. The underlying purpose is

29087 structure of GARLIC and PolyORB RPC receivers.
29088 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
29090 Simplify elaboration code for RCI packages.
29092 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29202 note that it applies to obsolete GNAT features, which was previously
29203 omitted. Second we contrast the behavior with that of the new
29204 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29205 Preliminary rewriting of GNAT & libraries chapter in order to take
29206 into account default project locations & new project manager

29440 value_factor_p instead of a raw binop construction to check for the
29441 position's alignment.

29448 Ed Schonberg <schonberg@adacore.com>
29450 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29451 with an implicit dereference as its prefix, use
29452 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29454 prefix is generated, if appropriate.
29456 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29457 dereference is rewritten to an explicit one, generate a reference to

29460 access value, if appropriate.
29462 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29463 emitting 'assigned but never read' warning on a variable on the basis

29479 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29480 subprogram which is Imported with convention Intrinsic if an
29481 External_Name argument is specified.
29482 (Process_Import_Or_Interface): Properly diagnose link name argument.

29539 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29540 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29541 the body, to ensure that warnings are properly emitted for each accept
29542 statement of a given task entry.

29570 (Remove_Next): Same cleanup
29572 2004-12-07 Thomas Quinot <quinot@adacore.com>
29574 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29575 used to record an implicit dereference as a read operation on its
29576 prefix when operating under -gnatc. Necessary to avoid spurious
29577 'variable assigned but never read' warnings in that mode.
29578 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29579 is a non-overloaded implicit dereference, call the above subprogram to
29580 ensure proper recording of references.
29582 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29584 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29632 2004-12-07 Vincent Celier <celier@adacore.com>
29634 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29635 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29636 and -eit to -ept. Added qualifier
29637 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29639 2004-11-27 Andreas Schwab <schwab@suse.de>

29645 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29646 internal implementation unit GNAT.Sockets.Thin,
29647 as their usage for sockets is non-portable (using the read and write
29648 functions from the system runtime library is fine on UNIX but won't

29705 new Others_Value and All_Others_Value objects.
29706 (struct attrib): Rename "arg" component as "args", since GCC expects a
29707 list of arguments in there.
29709 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29710 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29713 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29714 others_decl and all_others_decl instead of hardcoded dummy addresses
29715 to represent "others" and "all others" choices, which is cleaner and
29716 more flexible with respect to the possible eh pointer encoding policies.
29718 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29719 (process_attributes): Account for the naming change of the "args"
29720 attribute list entry component.
29722 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29723 cumulating attributes for different entities into a single list.
29724 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29725 attributes for the current entity and propagate first subtype
29726 attributes to other subtypes.
29727 <E_Procedure>: Attribute arguments are attr->args and not
29728 attr->arg any more.
29729 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29730 argument provided, as this is what GCC expects. Use NULL_TREE instead

29768 (First_RCI_Subprogram_Id): Document this constant.
29769 (Add_RAS_Access_TSS): Correct the setting of the Etype of the

29772 replaced with calls to Get_Library_Unit_Name_String. Previously there
29773 were several instances of the same code in different locations in the
29774 compiler; this checkin completes the replacement of all of these
29775 instances with calls to a common subprogram.
29776 Minor reformatting.
29778 * sem_dist.adb: Remove comment noting that RPC receiver generation
29779 should be disabled for RACWs that implement RASs.
29780 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29782 * sem_util.ads, sem_util.adb (Has_Stream): New function
29783 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29784 qualified name of a library unit into the name buffer.
29785 (Note_Possible_Modification): Generate a reference only
29786 if the context comes from source.
29788 * snames.ads (PCS_Names): New subtype corresponding to names of
29789 supported implementations of the Partition Communication Subsystem
29790 (PCS) (i.e. the runtime library support modules for the distributed
29793 2004-11-18 Robert Dewar <dewar@adacore.com>
29794 Ed Schonberg <schonberg@adacore.com>
29796 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29797 (Has_Rep_Pragma): New function
29798 (Has_Attribute_Definition_Clause): New function
29799 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29800 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29802 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29804 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29805 (Expand_Pragma_Psect_Object): New procedure
29806 These procedures contain the revised and cleaned up processing for
29807 these two pragmas. This processing was formerly in Sem_Prag, but
29808 is more appropriately moved here. The cleanup involves making sure
29809 that the pragmas are properly attached to the tree, and that no
29810 nodes are improperly shared.
29812 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29813 pragmas to Exp_Prag, which is more appropriate.
29814 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29815 check for duplicates Remove use of Is_Psected flag, no longer needed.
29816 Use new Make_String_Literal function with string.
29818 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29819 that are functions return universal values, that have to be converted
29820 to the context type.
29821 Use new Make_String_Literal function with string.
29822 (Get_Stream_Convert_Pragma): New function, replaces the use of
29823 Get_Rep_Pragma, which had to be kludged to work in this case.
29825 * freeze.adb: Use new Has_Rep_Pragma function
29827 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29828 function with string.
29829 Use new Has_Rep_Pragma function.
29831 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29834 2004-11-18 Robert Dewar <dewar@adacore.com>
29836 * errout.ads, errout.adb: (First_Sloc): New function
29838 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29839 check (-gnatyx) instead of being included as a redundant construct
29842 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29843 Style_Check_Order_Subprograms.
29845 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29846 stylesw.adb: Add Style_Check_Xtra_Parens
29848 * usage.adb: Add line for -gnatyx (check extra parens)
29850 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29852 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29853 Robert Dewar <dewar@adacore.com>
29855 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29856 discriminant of a constrained subtype, analyze the copy of the
29857 corresponding constraint, because in some cases it may be only
29858 partially analyzed.
29859 Removes long-lived ??? comments.
29861 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29862 handled controlled or secondary-stack expressions within the
29863 iteration_scheme of a loop.
29865 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29866 bounds that may contain functions calls, to prevent memory leaks when
29867 the bound contains a call to a function that uses the secondary stack.
29868 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29869 generate temporaries for loop bounds that might contain function calls
29870 that require secondary stack and/or finalization actions.
29872 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29873 selected component and the selector is overloadable (not just a
29874 function) treat as function call, Analyze_Call will disambiguate if
29876 (Analyze_Selected_Component): Do not generate an actual subtype for the
29877 selected component if expansion is disabled. The actual subtype is only
29878 needed for constraint checks.
29879 (Analyze_Allocator): If restriction No_Streams is set, then do
29880 not permit objects to be declared of a stream type, or of a
29881 composite type containing a stream.
29883 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29884 No_Streams no longer prohibits with'ing this package.
29886 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29887 discriminants, but the parent base has unknown discriminants, there is
29888 no discriminant constraint to inherit. Such a discrepancy can arise
29889 when the actual for a formal type with unknown discriminants is a
29890 similar private type whose full view has discriminants.
29891 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29892 do not permit objects to be declared of a stream type, or of a
29893 composite type containing a stream.
29895 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29897 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29898 protected operations.
29900 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29901 generated name, it complicates decoding in gdb and hinders debugging
29902 of protected operations.
29903 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29904 flag for the protected entry barrier function.
29905 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29906 flag for the protected entry function.
29908 2004-11-18 Nicolas Setton <setton@adacore.com>
29910 * expect.c: Define __unix__ when __APPLE__ is defined.
29912 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29913 Darwin-specific section.
29915 * lang-specs.h: Change the placement of the %1 marker.
29916 Works around the fact that gcc adds -fPIC by default under Darwin.
29918 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29920 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29921 type of the object with the packed array type, set the Analyzed flag
29922 on the object if it is an entity or simple indexed component, to avoid
29923 spurious type errors.
29925 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29927 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29928 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29929 separate line from the version message.
29931 2004-11-18 Ed Falis <falis@adacore.com>
29933 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29935 (init_float): Eliminate initialization of floating point status for
29936 AE653. The instructions have no effect for vThreads.
29938 2004-11-18 Vincent Celier <celier@adacore.com>
29940 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29941 gnatbind is invoked with -shared.
29943 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29945 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29946 for Detect_Blocking which is redundant with the check done within the
29947 procedure Protected_Single_Entry_Call.
29948 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29949 Detect_Blocking which is redundant with the check done within the
29950 procedure Protected_Single_Entry_Call.
29952 2004-11-18 Vincent Celier <celier@adacore.com>
29954 * makegpr.adb (Compile): Put the compiling switches (in package
29955 Compiler and on the command line) immediately after "-c", instead of
29956 at the end of the command line invocation of the compiler, when
29957 compiling a non-Ada file.
29958 (Build_Global_Archive): When there is no need to rebuild the archive,
29959 set Global_Archive_Exists, so that the archive is passed to the linker
29962 2004-11-18 Robert Dewar <dewar@adacore.com>
29963 Sergey Rybin <rybin@adacore.com>
29966 Remove extra paren check from list of checks for redundant constructs
29967 Add documentation of new -gnatyx style check (check extra parens)
29968 Remove paragraph about gnatelim debug options.
29970 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29971 objects rather than forbidding dependencies on the package Ada.Streams.
29973 * sinfo.ads: Add ??? note that we should document pragmas passed to
29976 * g-expect.ads: Fix a few typos in the comments.
29978 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29980 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29983 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29985 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29987 2004-11-07 Andreas Schwab <schwab@suse.de>
29989 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29991 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29994 * Makefile.in (darwin): Set soext to .dylib.
29996 2004-10-26 Vincent Celier <celier@gnat.com>
29997 Thomas Quinot <quinot@act-europe.fr>
29999 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30000 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30001 there is no use of GNAT.Sockets.Constants.
30002 Remove remaining pragma Import for C_Write
30003 Remove C_Read and C_Write from internal implementation unit
30004 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30005 the read and write functions from the system runtime library is fine
30006 on UNIX but won't work under Windows).
30008 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30009 (Check_Selector): Use C_Recv instead of C_Read.
30010 Selectors are the GNAT.Sockets abstraction to perform a select()
30011 call on a set of descriptors. To allow abortion of an ongoing
30012 select operation, some data is written to a dedicated socket that
30013 is always monitored.
30014 Under Windows, the write and read library functions cannot operate
30015 on sockets, so we need to use send and recv instead, which is portable
30016 across all supported platforms.
30018 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30019 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30020 (using the read and write functions from the system runtime library is
30021 fine on UNIX but won't work under Windows).
30023 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30025 * mlib-tgt-darwin.adb: New file.
30027 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30028 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30029 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30030 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30033 * Makefile.in: Add support for building shared libraries under Darwin.
30034 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30035 the low level EH init subprogram to be called from __gnat_initialize.
30037 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30038 indicates which options to pass to the archive indexer.
30040 * mlib-utl.adb: Add support for calling ranlib with additional
30041 options. This is needed for instance under Mac OS X.
30042 (Ranlib_Options): New global variable, used to store the potential
30043 options to pass to ranlib.
30044 (Ar): Use Ranlib_Options when spawning ranlib.
30045 (Initialize): Set the value of ranlib option.
30047 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30049 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30050 instead of 8K, to reflect the real potential needs for stack-checking
30053 2004-10-26 Pascal Obry <obry@gnat.com>
30055 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30057 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30058 Windows only the initial thread stack size can be set so it is good to
30059 start we a low stack size.
30060 The OS will adjust the size as needed.
30062 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30063 Nicolas Setton <setton@act-europe.fr>
30065 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30066 "__unix__" instead of "unix".
30067 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30068 sections were just mistakenly ignored. The former is
30069 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30070 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30071 of hpux. This prevents an unwanted definition of the symbol
30072 convert_addresses in adaint.o.
30074 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30076 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30077 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30079 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30081 * a-filico.ads, a-filico.adb: fix incorrect header.
30083 2004-10-26 Javier Miranda <miranda@gnat.com>
30085 * a-ststio.ads: Fix typo in identifier
30087 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30089 * sem_ch4.adb: Minor reformatting.
30091 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30093 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30094 enabled, check the result of unary and binary operations when the
30095 expression is the right-hand side of an assignment.
30097 2004-10-26 Vincent Celier <celier@gnat.com>
30099 * clean.adb (Delete): Do not output warnings when in quiet output and
30100 not in verbose mode.
30101 (Force_Deletions): New Boolean flag, defaulted to False
30102 (Delete): Only delete a file if it is writable, and when
30103 Force_Deletions is True.
30104 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30105 (Usage): Line for new switch -f
30106 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30109 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30111 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30112 JM type only if its size matches that of the wrapper. When a size is
30113 prescribed and the field is not aliased, remove the wrapper of a JM
30114 type only if the size is not greater than that of the packed array.
30115 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30118 2004-10-26 Geert Bosch <bosch@gnat.com>
30120 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30121 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30122 (Pred): Implement in terms of Succ.
30124 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30126 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30127 unchecked conversion is safe for in-place use if the expression of the
30128 conversion is safe.
30129 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30130 be expandable in place even if the aggregate does not come from source.
30131 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30132 designated object of an allocator in place, rather than building it
30133 first on the stack. The previous scheme forces a full copy of the array,
30134 and may be altogether unsusable if the size of the array is too large
30135 for stack allocation.
30137 2004-10-26 Robert Dewar <dewar@gnat.com>
30139 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30140 compares if the component is atomic.
30142 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30143 array assignment if the component type is atomic.
30145 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30146 Eric Botcazou <ebotcazou@act-europe.fr>
30148 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30149 is aliased and is a by_reference type, do not pass by copy.
30150 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30151 detect whether the call is in the right side of an assignment or
30152 the expression of an object declaration. Recurse on component
30153 association within aggregates.
30154 Call it in the condition that determines whether the temporary is
30155 necessary for correct stack-checking.
30157 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30159 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30160 RACW_Type, used in the PolyORB version.
30161 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30162 version and the GARLIC version.
30164 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30165 Rename RCI_Info to RCI_Locator for better consistency between the
30166 GARLIC and PolyORB versions of the distributed systems annex.
30167 (DSA_Implementation_Name): This enumeration lists the possible
30168 implementations of the Partition Communication Subsystem for the
30169 Distributed Systems Annex (DSA). The three available implementations
30170 are the dummy stub implementation (No_DSA), and two versions based on
30171 two different distribution runtime libraries: GARLIC and PolyORB. Both
30172 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30174 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30177 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30178 between the GARLIC and PolyORB versions of the distributed systems
30180 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30182 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30184 * gnat1drv.adb: Suppress calling the back end when
30185 Frontend_Layout_On_Target is true.
30187 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30189 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30190 Set_Read_Only): New subprograms.
30191 These new routines allow the user to set or unset the Owner execute
30192 and Owner write permission flags on a file.
30194 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30195 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30197 2004-10-26 Matthew Gingell <gingell@gnat.com>
30199 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30201 2004-10-26 Pascal Obry <obry@gnat.com>
30203 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30204 memory before the faulting page we properly test the process read
30205 access for this address using appropriate Win32 routine.
30206 (HPUX sections): guard with "__hpux__" instead of "hpux".
30208 2004-10-26 Robert Dewar <dewar@gnat.com>
30210 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30211 entry parameter if pragma Unreferenced set, since we do not properly
30212 handle the case of multiple parameters.
30214 2004-10-26 Vincent Celier <celier@gnat.com>
30216 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30217 (Ada_Objects_Path.Add): For a library project, add to the object path
30218 the library directory only if there is no object directory or if the
30219 library directory contains ALI files.
30220 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30222 2004-10-26 Vincent Celier <celier@gnat.com>
30224 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30225 extension of library projects.
30227 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30228 path defaults to ".:<prefix>/lib/gnat".
30229 (Parse): For an extending all project, allow direct import of a project
30230 that is virtually extended.
30232 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30233 the specified name is directly imported, return its ID. Otherwise, if
30234 an extension of this project is imported, return the ID of the
30237 2004-10-26 Robert Dewar <dewar@gnat.com>
30239 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30240 (Sub3): New procedure, used by Scaled_Divide
30241 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30242 correct more than one instance of failure to propagate carries
30244 (Double_Divide): Handle overflow case of largest negative number
30245 divided by minus one.
30247 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30248 the case of a quotient value out of range.
30251 2004-10-26 Robert Dewar <dewar@gnat.com>
30253 * s-bitops.adb (Bit_Eq): Remove redundant check.
30255 * s-bitops.ads: Minor comment updates
30256 Change some occurrences of Address to System.Address
30258 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30260 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30262 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30263 accessibility check to prefix that is a protected operation.
30265 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30267 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is

30271 Javier Miranda <miranda@gnat.com>
30273 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30274 current instance appears within a unit that is directly in the context
30276 Used to determine whether the body of the instance should be analyzed
30277 immediately after its spec, to make its subprogram bodies available
30278 for front-end inlining.
30279 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30280 constraint is not allowed on the component type (AARM 12.5.3(3))
30282 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30284 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30285 'Storage_Pool): enhance, document & limit detection of non-sharable
30288 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30290 * s-pooglo.ads: Add more documentation now that this pool is properly
30293 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30295 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30296 or protected type with discriminants, do not constrain the
30297 corresponding record type if the subtype declaration has no
30298 discriminant constraints. This can be the case in source code, or in
30299 the subtype declaration created to rename an actual type within an
30302 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30304 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30305 different kind of stub (possibly wrong name for file), do not check
30307 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30308 includes call to some function that returns an unconstrained type, do
30311 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30313 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30314 appear in the code for the main unit. Dependencies among units in the
30315 context of the main unit are established when those other units are
30316 compiled. Otherwise spurious elaboration constraints can generate
30317 incorrect elaboration circularities.
30319 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30320 Ed Schonberg <schonberg@gnat.com>
30322 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30323 subprogram is called with a parameter that is not an object name. This
30324 situation arises for some cases of illegal code, which is diagnosed
30325 later, and in this case it is wrong to call Is_Aliased, as that might
30326 cause a compiler crash.
30327 (Explain_Limited_Type): Refine previous fix to include
30328 inherited components of derived types, to provide complete information.
30330 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30331 is the prival for a protected object.
30332 It is necessary to mark this entity as a variable, in addition to
30333 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30334 modified to avoid checking the Aliased flag on entities that are not
30335 objects. (Checking that flag for non-objects is erroneous and could
30336 lead to a compiler crash).
30338 2004-10-26 Robert Dewar <dewar@gnat.com>
30340 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30341 X_Frac = 0.5, then we know that the number X must be positive.
30342 (Succ): Remove the same redundant test, and also fix the primary test
30343 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30345 (Decompose): Add fuller comments to spec
30347 2004-10-26 Pascal Obry <obry@gnat.com>
30349 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30350 validity (process must have read access). Set to 0 in all other cases.
30351 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30352 violation on Win32.
30353 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30354 segmentation violation.
30356 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30358 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30359 whose type is a constructed subtype of an aliased object with an
30360 unconstrained nominal subtype, convert the actual to the constructed
30361 subtype before taking its address.
30363 2004-10-26 Vincent Celier <celier@gnat.com>
30365 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30366 (Is_Path_Name_Case_Sensitive): New function
30368 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30369 (Base_Name, Simple_Name, Current_Directory, Compose,
30370 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30373 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30374 Vasiliy Fofanov <fofanov@act-europe.fr>
30375 Vincent Celier <celier@gnat.com>
30377 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30378 "memory management issues" section and document some of the useful
30379 memory pools provided as part of the GNAT library.
30380 Remove "virtual" from declaration of A::method2 in
30381 the simple example of Ada/C++ mixed system.
30382 Library Projects may be virtually extended: their virtual extensions
30383 are not Library Projects.
30384 Added section on extending project hierarchies.
30386 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30388 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30390 (__gnat_portable_spawn): Remove const.
30392 * mingw32.h (MAXPATHLEN): Check for previous definition.
30394 2004-10-17 Matthias Klose <doko@debian.org>
30396 * gnatvsn.ads: Set gnat library version to 4.0.
30398 2004-10-05 Vincent Celier <celier@gnat.com>
30400 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30402 2004-10-04 Laurent Guerby <laurent@guerby.net>
30405 * Makefile.in: Define and use RANLIB_FLAGS.
30407 2004-10-04 Pascal Obry <obry@gnat.com>
30409 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30410 other x86 platforms).
30412 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30414 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30415 in general and triggers stack alignment adjustment for thread entry
30416 points on targets where this is necessary.
30418 2004-10-04 Bernard Banner <banner@gnat.com>
30421 * Makefile.in: Add section for powerpc linux
30422 Add variant i-vxwork-x86.ads
30424 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30426 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30428 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30429 table registration calls when need be. Ensures no reference to the crt
30430 ctors symbol are issued in the SJLJ case, which avoids possible
30431 undefined symbol errors in the case of modules to be statically linked
30434 2004-10-04 Javier Miranda <miranda@gnat.com>
30436 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30437 in-line the code corresponding to subprogram Analyze_Actuals. In
30438 addition, analyze the actuals only in case of subprogram call.
30440 2004-10-04 Ed Falis <falis@gnat.com>
30442 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30444 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30446 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30447 in the documentation.
30449 2004-10-04 Robert Dewar <dewar@gnat.com>
30451 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30453 (Analyze_Block_Statement): Add circuitry to detect following dead code
30454 (Check_Unreachable_Code): Handle case of block exit
30456 2004-10-04 Robert Dewar <dewar@gnat.com>
30458 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30459 (XMatchD): Avoid warning for Logic_Error call
30461 2004-10-04 Robert Dewar <dewar@gnat.com>
30463 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30464 consider expressions buried within a procedure actual to be an actual.
30465 This caused some blowups with uses of packed slices within a procedure
30468 2004-10-04 Robert Dewar <dewar@gnat.com>
30470 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30471 longer need to be initialized to zero.
30472 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30473 initialized to zero.
30475 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30476 considered valid, even if the representation is modular. That's correct
30477 now that we no longer initialize packed modular arrays to zero.
30479 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30480 suffixes. These are now documented as the only cases in which the
30481 debugger ignores outer records.
30482 Previously, the spec allowed arbitrary suffixes for this purpose.
30483 Change name of LJM to JM for packed array pad records
30484 Create separate section on packed array handling, and add a whole new
30485 set of comments to this section describing the situation with packed
30486 modular types and justification requirements depending on endianness.
30488 2004-10-04 Robert Dewar <dewar@gnat.com>
30490 * a-except.adb: Add a comment for last change
30492 * einfo.ads: Minor spelling correction in comment
30494 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30496 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30499 * sem_util.ads: Minor comment update
30501 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30503 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30504 Inline_Always when in Configurable_Run_Time mode.
30506 * sem_prag.adb (Process_Convention): If entity is an inherited
30507 subprogram, apply convention to parent subprogram if in same scope.
30508 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30509 when in Configurable_Run_Time mode.
30511 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30513 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30514 class_wide type after component list has been inherited.
30516 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30518 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30519 Denotes_Previous_Actual, to handle properly the case of a private
30520 actual that is also the component type of a subsequent array actual.
30521 The visibility status of the first actual is not affected when the
30522 second is installed.
30523 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30524 make fully recursive the treatment of formals of packages declared
30526 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30527 the above on exit from an instantiation.
30528 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30529 current instantiation which is now complete.
30530 (Analyze_Package_Instantiation): No instantiated body is needed if the
30531 main unit is generic. Efficient, and avoid anomalies when a instance
30532 appears in a package accessed through rtsfind.
30534 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30536 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30537 do not generate a declaration for a temporary if the call is part of a
30538 library-level instantiation.
30540 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30542 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30543 searching for a limited component to flag.
30545 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30546 expansion of Input, to account for the fact that the implicit call
30547 generated by the attribute reference must freeze the user-defined
30548 stream subprogram. This is only relevant to 'Input, because it can
30549 appear in an object declaration, prior to the body of the subprogram.
30551 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30552 expansion can proceed and further errors uncovered.
30553 (Minor clean up): Fix cases of using | instead of \ for continuation
30556 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30558 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30560 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30561 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30562 Use gcc_assert and gcc_unreachable.
30564 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30565 specified alignment before validating size.
30566 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30567 stripped-down declaration for the type of the inner field when making
30570 * utils.c (finish_record_type): Do not compute the size in units
30571 incrementally. Instead compute it once for the rep clause case.
30572 Use gcc_assert and gcc_unreachable.
30574 2004-10-04 Vincent Celier <celier@gnat.com>
30576 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30578 (Is_Valid_Path_Name): Take '/' as a directory separator.
30580 2004-10-04 Vincent Celier <celier@gnat.com>
30582 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30583 (Extended_Project) only if Extended_Project is defined, to avoid
30585 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30587 (Parse_Single_Project): Ditto.
30589 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30590 Add_To_Project_Path for virtual projects.
30592 2004-10-04 Vincent Celier <celier@gnat.com>
30594 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30595 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30596 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30597 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30598 parameter Options_2.
30600 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30601 Build_Dynamic_Library with an empty Options_2.
30603 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30606 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30607 directory separator, if any.
30608 (Gprmake): Do not allow mains on the command line for library projects.
30609 Do not attempt to link when the project is a library project.
30610 (Library_Opts): New table to store Library_Options.
30611 (Build_Library): If Library_Options is specified, pass these options
30612 when building a shared library.
30614 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30616 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30617 the end of this procedure now that the unlock operation was inserted
30620 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30622 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30623 corresponding to the Preallocated_Stacks flags in System.
30624 (Get_Target_Parameters): Including the processing for
30625 Preallocated_Stacks.
30627 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30628 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30636 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30637 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30638 used to signal whether the compiler creates the required stacks and
30639 descriptors for the different tasks (when True) or it is done by the
30640 underlying operating system at run time (when False).
30641 It is initially set to False in all targets.
30643 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30644 if it is supported by the target.
30645 (Make_Task_Create_Call): Pass the stack address if it has been
30646 previously created. Otherwise pass a Null_Address.
30648 * snames.adb: Add _stack.
30650 * snames.ads: Add Name_uStack. Required to allow the expander to
30651 statically allocated task stacks.
30653 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30654 Stack_Address argument.
30655 Check that its value is equal to Null_Address because this target does
30656 not support the static stack allocation.
30658 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30660 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30663 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30665 * exp_dist.adb: Split declaration of asynchronous flag out of
30666 Add_RACW_Read_Attribute.
30667 Minor reformatting for better alignment with PolyORB version.
30668 Store the entity for the asynchronous flag of an RACW, rather than the
30669 expression, in the asynchronous flags table. This will allow this flag
30670 to be used in other subprograms beside Add_RACW_Read_Attribute.
30672 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30674 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30675 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30676 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30677 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30678 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30679 sockets constant MSG_NOSIGNAL (Linux-specific).
30680 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30681 all Send operations.
30682 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30683 from trigerring SIGPIPE.
30684 Rename components to avoid clash with Ada 2005 possible reserved
30686 (Check_Selector): When the select system call returns with an error
30687 condition, propagate Socket_Error to the caller.
30689 2004-10-01 Jan Hubicka <jh@suse.cz>
30691 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30693 2004-09-23 Robert Dewar <dewar@gnat.com>
30696 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30697 instead do this at freeze time (we won't do it if there is an address
30699 Change "pragma inline" to "pragma Inline" in information and error
30701 Minor reformatting.
30703 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30704 right way of doing things after all.
30705 (Freeze_Entity): For object, set Is_Public for imported entities
30706 unless there is an address clause present.
30708 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30710 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30711 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30712 ensures proper handling of types with rep clauses, which might have
30713 their TYPE_SIZE set already.
30715 2004-09-21 Robert Dewar <dewar@gnat.com>
30717 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30718 packed array types in both little- and big-endian cases. This change
30719 ensures that we no longer count on the unused bits being initialized
30720 for such types (and in particular ensures that equality testing will
30721 only read the relevant bits).
30722 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30723 These changes mean that we no longer need to initialize small packed
30725 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30726 optimization to an LJM field as to its parent field.
30728 * ada-tree.h, trans.c, utils.c, utils2.c:
30729 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30731 2004-09-20 Jan Hubicka <jh@suse.cz>
30733 * utils.c (gnat_finalize): Remove.
30734 (end_subprog_body): Directly call cgraph_finalize_function;
30735 do not lower the nested functions.
30737 2004-09-20 Robert Dewar <dewar@gnat.com>
30740 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30741 if an address clause is present, since that means that the Import
30744 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30746 * 5tsystem.ads: Removed, no longer used.
30748 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30749 Zack Weinberg <zack@codesourcery.com>
30751 * ada-tree.def: Use tree_code_class enumeration constants
30752 instead of code letters.
30753 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30754 Update for new tree-class enumeration constants.
30756 2004-09-17 Vincent Celier <celier@gnat.com>
30758 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30759 capabilities of the general project manager.
30761 2004-09-09 Vincent Celier <celier@gnat.com>
30763 * a-direct.ads: Add pragma Ada_05

30790 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30792 (Attrs, Package_Attributes): Table instantiations moved from the body to
30793 the private part to be accessible from Prj.Attr.PM body.

30853 raise Program_Error if called from a protected operation.
30855 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30856 the protected action nesting level.
30857 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30858 protected action nesting level.
30859 (Unlock): When pragma Detect_Blocking is active decrease the protected
30860 action nesting level.
30862 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30863 Protected_Action_Nesting.
30865 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30866 Common_ATCB record. It contains the dynamic level of protected action
30867 nesting for each task. It is needed for checking whether potentially
30868 blocking operations are called from protected operations.
30869 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30870 Detect_Blocking is active or not in the partition.
30872 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30906 contains the required machinery for handling that.
30908 * sem_util.ads: Change comment associated to procedure
30909 Check_Potentially_Blocking_Operation.
30910 This procedure does not insert a call for raising the exception because
30911 that is currently done by the run time.
30913 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30915 * init.c: Add the global variable __gl_detect_blocking that indicates
30916 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30917 making the pragma available at run time.
30918 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30921 pragma Detect_Blocking is active.
30923 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30925 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30926 DB is found in the ali file. Any unit compiled with pragma
30927 Detect_Blocking active forces its effect in the whole partition.
30929 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30930 Detect_Blocking is active and delay is called from a protected
30933 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

30947 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30948 Update API in placeholder implemetation of s-parint to reflect changes
30949 in distribution runtime library.
30951 * sem_ch3.adb (Expand_Derived_Record): Rename to
30952 Expand_Record_Extension.
30954 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30955 primitive operations of potentially distributed object types that have
30956 non-controlling anonymous access formals.
30958 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30960 New implementation of expansion for remote access-to-subprogram types,
30961 based on the RACW infrastructure.
30962 This version of sem_dist is compatible with PolyORB/DSA as well as
30965 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30966 Asynchrronous that applies to a remote access-to-subprogram type, mark
30967 the underlying RACW type as asynchronous.
30969 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30970 __gnat_using_gnu_linker to 1.

30981 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30982 a component declaration must remain attached at that point in the
30983 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30984 It is therefore necessary to take a copy of the expression when building
30985 the corresponding assignment statement in the init proc.
30986 As a side effect, in the case of a derived record type, we now see the
30987 original expression, without any rewriting that could have occurred
30988 during expansion of the ancestor type's init proc, and we do not need
30989 to go back to Original_Node.
30991 * exp_ch3.ads (Expand_Derived_Record): Rename to
30992 Expand_Record_Extension.
30994 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

30999 subprogram. The proxy object is used as the designated object
31000 for RAS values on the same partition (unless All_Calls_Remote applies).
31001 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31002 System.Partition_Interface.Get_Unique_Remote_Pointer.

31007 New implementation of expansion for remote access-to-subprogram types,
31008 based on the RACW infrastructure.
31010 * exp_dist.ads (Copy_Specification): Update comment to note that this
31011 function can copy the specification from either a subprogram
31012 specification or an access-to-subprogram type definition.
31014 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31016 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31017 in an instance, between an explicit subprogram an one inherited from a
31018 type derived from an actual.
31020 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31021 add a polling call if the subprogram is to be inlined by the back-end,
31022 to avoid repeated calls with multiple inlinings.
31024 * checks.adb (Apply_Alignment_Check): If the expression in the address
31025 clause is a call whose name is not a static entity (e.g. a dispatching
31026 call), treat as dynamic.

31030 * g-trasym.ads: Minor reformatting
31032 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31041 2004-09-09 Pascal Obry <obry@gnat.com>
31043 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31044 enable map file generation. Add the right option to generate the map
31045 file if Map_File is set to True.
31047 * gnatdll.adb (Gen_Map_File): New variable.
31048 (Syntax): Add info about new -m (Map_File) option.

31076 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31077 of variable length temporaries for function return now that the
31078 back-end and gigi support it.

31155 consistent treatment of entity references contained within the
31156 enclosed procedure call.
31158 2004-09-01 Vincent Celier <celier@gnat.com>
31160 * bindgen.adb: (Set_EA_Last): New procedure

31247 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31248 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31249 option and not mdll anymore. Update comment.
31251 2004-08-16 Pascal Obry <obry@gnat.com>

31335 returning C.int, to avoid using a derived boolean type.
31337 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

33220 2004-06-07 Thomas Quinot <quinot@act-europe.fr>
33222 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
33223 the index of the last element is Units.Last, not Units.Table'Last
33224 (which is usually not a valid index within the actually allocated
33225 storage for the table).
33227 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
33228 determines whether to generate a call to a checked storage pool

33262 hand side. Warnings are now properly emitted when variables or prefixes
33263 are assigned but not read.
33265 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33266 left hand side referenced variables. Private access types do not

33290 interpretations for rewritten right operand.
33291 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33717 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
33718 subtype, check visible entities in base type.
33720 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
33721 actions if the object is a renaming.
33723 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
33724 Check_Formal_Package_Instance, to determine more precisely when the
33725 formal and the actual denote the same entity.
33727 2004-05-14 Javier Miranda <miranda@gnat.com>
33729 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33731 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33732 corresponding to a private_with must be removed from visibility; it
33733 will be made visible later, just before we analyze the private part of
33735 (Check_Private_Child_Unit): Allow private_with clauses in public
33737 (Install_Siblings): Make visible the private entities of private-withed
33739 (Install_Withed_Unit): Do not install the private withed unit if we
33740 are compiling a package declaration and the Private_With_OK flag was
33741 not set by the caller. These declarations will be installed later,
33742 just before we analyze the private part of the package.
33744 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
33745 during the evaluation of the expression that initializes the object,
33746 decorate it with the expected type to avoid cascade errors.
33749 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
33750 subprogram we have to install the private_with clauses after its
33751 specification has been analyzed (as documented in AI-262.TXT).
33753 * sem_ch8.adb (Has_Private_With): New function. Determines if the
33754 current compilation unit has a private with on a given entity.
33755 (Find_Direct_Name): Detect the Beaujolais problem described in
33758 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
33759 provides the functionality of the function Is_Ancestor that was
33760 previously available in sem_ch10. It has been renamed to avoid
33763 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
33765 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
33767 * utils.c (build_vms_descriptor): Use SImode pointers.

33927 Merge from tree-ssa-20020619-branch.
33929 * config-lang.in (boot_language, build_by_default): Set

33946 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
33949 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
33951 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
33953 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
33954 Fixes undefined symbols in IA64 gnatlib.
33956 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
33958 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
33959 Short_Address). This will be moved to system.auxdec.

33963 * sem_util.adb: Replace test for presence of a node that is always
33964 present with a call to Discard_Node.
33966 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33967 Analyze on the library unit node after generation of distribution stub
33968 constructs. The call was a no-op because Unit_Node has already been
33969 Analyzed, and the tree fragments for the distribution stubs are
33970 analyzed as they are inserted in Exp_Dist.
33971 Update comment regarding to distribution stubs to reflect that we
33972 do not generate stub in separate files anymore.
33974 * einfo.ads: Clarify the fact that a tagged private type has the
33975 E_Record_Type_With_Private Ekind.
33977 * erroutc.adb: Minor reformatting
33979 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
33980 values if line length is increased using -gnatyM (noticed during code
33983 * eval_fat.adb: Minor reformatting

33986 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33989 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
33990 has been rewritten as an explicit dereference, retrieve type of
33991 original node to check for possibly unconstrained record type.
33993 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33995 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33996 overriding, use the operation of the parent unconditionally.
33998 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33999 operation when either operand is a literal, to avoid further
34002 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
34003 overridden by a previous explicit declaration, mark the previous entity
34006 * sem_disp.adb (Check_Dispatching_Operation): New predicate
34007 Is_Visibly_Controlled, to determine whether a declaration of a
34008 primitive control operation for a derived type overrides an inherited
34009 one. Add warning if the explicit declaration does not override.
34011 2004-05-10 Vincent Celier <celier@gnat.com>
34013 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
34014 some cases when the sources are no longer present.
34016 * make.adb (Collect_Arguments): Fail if an external source, not part
34017 of any project need to be compiled, when switch -x has not been
34020 * makeusg.adb: Document new switch -x
34022 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
34023 defaulted to False.
34025 * switch-m.adb (Scan_Make_Switches): New switch -x
34027 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
34028 gnatmake switch -x.
34030 * gnat_ugn.texi: Document new gnatmake switch -x
34032 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
34034 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34036 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34037 (process_attributes): Likewise.
34039 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34041 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34043 2004-05-10 Robert Dewar <dewar@gnat.com>
34045 * gnat_ugn.texi: Document that for config pragma files, the maximum
34046 line length is always 32767.
34048 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34049 literals is now allowed.
34051 * gnat-style.texi: Remove statement about splitting long lines before
34052 an operator rather than after, since we do not follow this rule at all.
34053 Clarify rule (really lack of rule) for spaces around exponentiation
34055 * sem_elim.adb: Allow concatenation of string literals as well as a
34056 single string literal for pragma arguments.
34058 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34060 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34061 written for append case.
34063 * frontend.adb: Changes to avoid checking max line length in config
34066 * g-os_lib.ads: Minor reformatting
34068 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34069 wrong in any case. Instead use standard value. Noticed during code

35140 * sem_prag.adb (Set_Exported): Warn about making static as result of
35141 export only when the export is coming from source. This may be not
35142 be true e.g. on VMS where we expand export pragmas for exception codes
35143 together with imported or exported exceptions, and we don't want the
35144 user to be warned about something he didn't write.
35146 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
35148 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
35149 duplication between normal entities and those declared as renamings.

35249 specified radix_digits is greater or equal to machine_mantissa.
35251 2004-04-05 Javier Miranda <miranda@gnat.com>
35253 * par-ch3.adb: Complete documentation of previous change
35254 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

35267 as is done for non-private derived record types.
35269 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35270 Ada 2005 AI-310: an abstract non-dispatching operation is not a

35274 expression is Null and target type is not an access type (e.g. a

35279 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35280 statement whose right-hand side is an inlined call, save a copy of the
35281 original assignment subtree to preserve enough consistency for
35282 Analyze_Assignment to proceed.
35284 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35285 complete assignment subtree which is now unnecessary, as the expansion
35286 of inlined call has been improved to preserve a consistent assignment
35287 tree. Note_Possible_Modification must be called only
35288 after checks have been applied, or else unnecessary checks will
35291 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35292 of explicit dereferences that do not Come_From_Source:
35293 - be selective on cases where we must go back to the dereferenced
35294 pointer (an assignment to an implicit dereference must not be
35295 recorded as modifying the pointer);
35296 - do not rely on Original_Node being present (Analyze_Assignment
35297 calls Note_Possible_Modification on a copied tree).
35299 * sem_warn.adb (Check_References): When an unset reference to a pointer
35300 that is never assigned is encountered, prefer '<pointer> may be null'
35301 warning over '<pointer> is never assigned a value'.

35370 a string literal, create a temporary for it, constant folding only
35371 handles scalars here.
35373 2004-04-01 Vincent Celier <celier@gnat.com>

35557 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35559 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35560 current unit cannot be inlined if it appears in the body of a withed
35561 unit, to avoid order of elaboration problems in gigi.
35563 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35564 information for protected (wrapper) operation as well, to simplify gdb
35567 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35610 a classwide type (for which Is_Object_Reference holds), but it can
35611 also be a value conversion for an access-to-classwide type. In the
35612 latter case, there is an implicit dereference, and the original node
35613 for the prefix does not verify Is_Object_Reference.

35693 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35694 declaration for a child subprogram body that acts as a spec, indicate
35695 that the entity in the declaration needs debugging information.
35697 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35698 full view if the subtype is created for a constrained record component;
35699 gigi has enough information to construct the record, and there is no
35700 place in the tree for the declaration.
35702 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35703 serial number for the dummy body that is built for analysis, to avoid
35704 inconsistencies in the generation of internal names when compiling
35707 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35709 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35712 2004-03-22 GNAT Script <nobody@gnat.com>
35714 * Make-lang.in: Makefile automatically updated
35716 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

35741 Minor reformatting.
35743 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35745 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35746 as regular exception objects and not as mere integers representing the
35747 condition code. The latter approach required some dynamics to mask off
35748 severity bits, which did not fit well into the GCC table based model.
35749 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35750 exception data objects. We don't it and it would conflict with the other
35751 external symbol we have to generate for such exceptions.
35753 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35754 the special code for VMS exceptions, since these are now represented
35755 as regular exceptions objects.
35757 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35759 * decl.c (debug_no_type_hash): Remove.

35763 2004-03-19 Laurent Guerby <laurent@guerby.net>
35765 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35766 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35768 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35770 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

35790 * adaint.c: Update comments.
35792 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35793 GNATLIB_SHARED for FreeBSD.
35795 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35797 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35798 When needed (stack checking) the stack size is retrieved
35799 from the VxWorks kernel.
35801 * Makefile.in: Flag -nostdinc is required when building the run time
35802 for avoiding looking for files in the base compiler.
35803 Add the VxWorks specific version of the package body for
35804 System.Stack_checking.Operations (5zstchop.adb).
35806 * Make-lang.in: Add the object file for
35807 System.Stack_Checking.Operations.

35815 checking from this package to package System.Stack_Checking.Operations.
35816 This way, stack checking operations are only linked in the final
35817 executable when using the -fstack-check flag.
35819 2004-03-18 Doug Rupp <rupp@gnat.com>
35821 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35831 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35832 the procedures Add_To_Path_File.
35833 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35834 making sure that each directory is present only once and, for object
35835 dirs, when a directory already present is added, the duplicate is
35836 removed and the directory is always put as the last in the table.
35837 Write the path files at the end of these accumulations.
35839 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35840 Files_Htable for all sources.
35842 * prj-proc.adb (Process): Remove restrictions between not directly
35843 related extending projects.

35851 parameter Trusted_Mode.
35853 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35855 * scn.adb (Determine_License): Take into account a degenerated case
35856 when the source contains only comments.
35858 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35860 * sem_warn.adb (Check_References): For a warning on a selected
35861 component that does not come from source, locate an uninitialized
35862 component of the record type to produce a more precise error message.
35864 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35866 * 3zsoccon.ads: Fix multicast options.
35868 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35871 2004-03-15 Robert Dewar <dewar@gnat.com>

35874 pragma used for a private type.
35876 * lib-xref.adb (Generate_Reference): Do not generate warning if
35877 reference is in a different unit from the pragma Unreferenced.
35879 * 5vtpopde.adb: Minor reformatting
35880 Fix casing of To_Task_ID
35882 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35883 flag if we have an unchecked conversion to an access type in the same
35886 2004-03-15 Geert Bosch <bosch@gnat.com>
35888 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35889 imaginary parts, use Double precision throughout.
35891 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35892 we want to be able to compile run-time with -gnata for testing, but
35893 this may also be instantiated in user code that is compiled with -gnata.
35895 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35897 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35898 codes. Having a separate type for this is useful to enforce consistency
35899 throughout the various run-time units.
35900 (Exception_Data): Use Exception_Code for Import_Code.
35902 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35910 component, now reflected by an exported accessor.
35911 (is_handled_by): New routine to compute whether the propagated
35912 occurrence matches some handler choice specification. Extracted out of
35913 get_action_description_for, and expanded to take care of the VMS
35915 (get_action_description_for): Use is_handled_by instead of an explicit
35916 complex condition to decide if the current choice at hand catches the
35917 propagated occurrence.
35919 * raise.h (Exception_Code): New type for C.
35921 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35922 System.Standard_Library.Exception_Code, to allow references from the
35923 pragma import/export expander.
35925 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35926 New accessors to allow easy access to GNAT exception data
35928 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35929 redundant Handled_By_Others component, helper for the personality
35930 routine which will now be able to call the appropriate exception data
35933 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35934 component of Standard_Exception_Type to be the closest possible to
35935 Exception_Code in System.Standard_Library, that we cannot get at this
35936 point. Expand a ??? comment to notify that this type node should
35937 probably be rewritten later on.
35939 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35940 registration call to include a pointer to the exception object in the
35943 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35944 instead of int and explicit bitmasks.
35946 2004-03-15 Vincent Celier <celier@gnat.com>
35948 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35949 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35951 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35952 longer needed now that it is in the spec of
35953 System.Tasking.Task_Attributes.
35955 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35957 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35959 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35961 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35962 taken care of in Scan_Make_Arg.
35963 (Scan_Make_Arg): Add the executable suffix only if the argument
35964 following -o, in canonical case, does not end with the executable
35965 suffix. When in verbose mode and executable file name does not end
35966 with executable suffix, output the executable name, in canonical case.
35968 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35969 to avoid warnings when instantiating Ada.Task_Attributes.
35972 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35973 in the correct order.
35975 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35980 directory, instead of the Value.
35981 (Find_Source_Dirs): Remove useless code & comments.
35983 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35985 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35986 tagged type is inherited, and the parent operation is not frozen yet,
35987 force generation of a freeze node for the inherited operation, so the
35988 corresponding dispatch entry is properly initialized.
35989 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35990 when looking for user-defined equality operation.
35992 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35993 boolean when locating primitive equality of tagged component.
35995 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35996 bit-aligned field and the right-hand side a string literal, introduce
35997 a temporary before expanding assignment into a loop.
35999 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36000 priority in full, to ensure that any expanded subepxressions of it are
36001 elaborated in the scope of the init_proc.
36003 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36004 after object declaration, skipping over code that may have been
36005 generated for validity checks.
36007 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36008 discriminants, ignore the known discriminants of its full view, if
36009 any, to check legality.
36011 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36012 component if type has unknown discriminants.
36013 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36014 null if type has unknown discriminants.
36016 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36017 for end label when present.
36019 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36020 temporary file, rather than an empty string.
36022 2004-03-15 Ed Falis <falis@gnat.com>
36024 * s-thread.adb: Removed, no longer used.
36026 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36046 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36047 Insert_Dereference_Action when rewriting an implicit dereference into
36048 an explicit one, this will be taken care of during expansion of the
36049 explicit dereference.
36050 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36051 of non-packed slices, since the dereference action generated by
36052 expansion of the explicit dereference is needed in any case.
36053 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36054 analyze and resolve the rewritten explicit dereference so it is seen
36056 (Insert_Dereference_Action): This procedure is now called only for the
36057 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36058 dereferences that do not come from source (including explicit
36059 dereferences resulting from rewriting implicit ones), but do not
36060 recursively insert a check for the dereference nodes contained within
36062 (Insert_Dereference_Action): Clarify and correct comment.

36939 checks for bitfield creation are triggered.
36940 (finish_record_type): During last pass over the fields, clear

37281 2004-01-12 Ed Schonberg <schonberg@gnat.com>
37283 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
37284 generated to rename a generic actual, go to the actual itself, the
37285 subtype is not a user-visible entity.
37287 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
37288 part is a private subtype, reset the visibility of its full view, if
37289 any, to be consistent.
37292 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
37293 to use a generic package G as a formal package for another generic

37325 2004-01-05 Robert Dewar <dewar@gnat.com>
37327 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
37328 be modified by the binder generated main program if the -D switch is
37331 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37332 imported functions (since now we expect this to be done for imported
37335 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37336 Minor reformatting throughout
37338 * 5zinit.adb: Minor reformatting
37339 Add 2004 to copyright date
37340 Minor changes to avoid -gnatwa warnings
37341 Correct some instances of using OR instead of OR ELSE (noted while
37342 doing reformatting)
37344 * sprint.adb: Minor updates to avoid -gnatwa warnings
37346 * s-secsta.ads, s-secsta.adb:
37347 (SS_Get_Max): New function to obtain high water mark for ss stack
37348 Default_Secondary_Stack is not a constant since it may be modified by
37349 the binder generated main program if the -D switch is used.
37351 * switch-b.adb: New -Dnnn switch for binder
37354 Make -gnatg imply all warnings currently in -gnatwa
37356 * vms_conv.adb: Minor reformatting
37357 Add 2004 to copyright notice

37380 lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
37381 Minor reformatting and code clean ups.
37382 Minor changes to prevent -gnatwa warnings
37384 * ali.adb: Minor reformatting and cleanup of code
37385 Acquire new SS indication of secondary stack use from ali files
37387 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37388 (since now we expect this to be done for imported functions)
37390 * bindgen.adb: Generate call to modify default secondary stack size if
37393 * bindusg.adb: Add line for new -D switch
37395 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37396 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37397 Add circuitry for both records and arrays to avoid gigi
37398 processing if the type involved has non-bit-aligned components
37400 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37401 N_String_Literal node always references an E_String_Literal_Subtype
37402 entity. This may not be true in the future.
37403 (Possible_Bit_Aligned_Component): Move processing of
37404 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37406 * exp_ch6.adb (Expand_Thread_Body): Pick up
37407 Default_Secondary_Stack_Size as variable so that we get value modified
37408 by possible -Dnnn binder parameter.
37410 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37411 (Type_May_Have_Bit_Aligned_Components): New function.
37413 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37421 importing constant atomic/volatile objects.
37422 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
37423 unless explicit Pure_Function pragma given, to avoid insidious bug of
37424 call to non-pure imported function getting eliminated.

37446 * rtsfind.adb (Load_Fail): Give full error message in configurable
37447 run-time mode if all_errors mode is set. This was not done in the case
37448 of a file not found, which was an oversight.
37449 Note if secondary stack unit is used by compiler.
37451 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37452 ineffective elaborate all pragmas on non-visible packages (this
37453 happened when a renamed subprogram was called). Now the elaborate all
37454 always goes on the package containing the renaming rather than the one
37455 containing the renamed subprogram.
37457 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37458 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37460 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37461 has an Etype that references an E_String_Literal.
37462 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37463 always references an E_String_Literal_Subtype entity. This may not
37464 be true in the future.
37466 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37469 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37472 2004-01-05 Ed Falis <falis@gnat.com>
37474 * g-debuti.adb: Replaced direct boolean operator with short-circuit
37477 2004-01-05 Vincent Celier <celier@gnat.com>
37479 * bld.adb: Minor comment updates
37480 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37483 * make.adb (Gnatmake): Special process for files to compile/check when
37484 -B is specified. Fail when there are only foreign mains in attribute
37485 Main of the project file and -B is not specified. Do not skip bind/link
37486 steps when -B is specified.
37488 * makeusg.adb: Document new switch -B
37490 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
37492 * switch-m.adb: (Scan_Make_Switches): Process -B switch
37494 * vms_data.ads: Add new GNAT PRETTY qualifier

37499 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
37502 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
37503 Set_Identifier_Casing.
37505 * decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
37506 has size that overflows.
37508 2004-01-05 Gary Dismukes <dismukes@gnat.com>
37510 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
37511 -gnatwa warning on static condition.
37513 2004-01-05 Doug Rupp <rupp@gnat.com>
37515 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
37517 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37519 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37520 all attributes, including read-only attribute.
37522 2004-01-05 Pascal Obry <obry@gnat.com>
37524 * bindgen.adb (Gen_Object_Files_Options): Generate the new shared
37525 library naming scheme.
37527 * mlib-prj.adb (Build_Library): Generate different names for the static
37528 or dynamic version of the GNAT runtime. This is needed to support the
37529 new shared library naming scheme.
37530 (Process_Binder_File): Add detection of shared library in binder file
37531 based on the new naming scheme.
37533 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37534 scheme for the shared runtime libraries.
37537 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37539 (install-gnatlib): Do not create symlinks for shared libraries.
37540 (gnatlib-shared-default): Idem.
37541 (gnatlib-shared-dual-win32): New target. Not used for now as the
37542 auto-import feature does not support arrays/records.
37543 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37544 (gnatlib-shared-vms): Fix shared runtime libraries names.
37546 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37547 dependent runtime shared library name.
37549 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37551 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37554 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37556 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37557 protected objects when allocator has a subtype indication, not a
37558 qualified expression. Note that qualified expressions may have to be
37559 checked when limited aggregates are implemented.
37561 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37562 pure, emit warning.
37563 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37564 subprogram is imported, remove warning.
37566 2004-01-05 Geert Bosch <bosch@gnat.com>
37568 * s-poosiz.adb: Update copyright notice.
37569 (Allocate): Use Task_Lock to protect against concurrent access.
37570 (Deallocate): Likewise.
37572 2004-01-05 Joel Brobecker <brobecker@gnat.com>
37574 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

37592 * stamp-xgnatug: New stamp file.
37593 * Make-lang.in (stamp-xgnatug): New stamp file and comment.

37595 (ada/gnat_ug_unx.texi, ada/gnat_ug_vwx.texi, ada/gnat_ug_vms.texi
37596 ada/gnat_ug_wnt.texi): Update to depend on stamp-xgnatug.
37598 2003-12-17 Ed Falis <falis@gnat.com>
37600 * a-elchha.adb (Tailored_Exception_Information): made Info constant to

37604 Ada.Exceptions.Last_Chance_Handler.
37606 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
37608 * cstand.adb (Create_Standard): Change the way how the declaration of
37609 the Duration type is created (making it the same way as it is for all
37610 the other standard types).
37612 2003-12-17 Robert Dewar <dewar@gnat.com>
37614 * s-crtl.ads: Fix header format
37615 Change Pure to Preelaborate
37617 2003-12-17 Ed Schonberg <schonberg@gnat.com>
37619 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
37620 the expression type only if it is declared in the current unit.
37622 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37623 are universal and already analyzed, as can occur in constrained
37624 subcomponents that depend on discriminants, when one constraint is a
37627 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37628 type Any_Fixed is legal as the argument of a conversion, if only one
37629 fixed-point type is in context.
37631 2003-12-17 GNAT Script <nobody@gnat.com>

37642 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37643 (Gnatchop): Do not set failure status when reporting the number of
37646 2003-12-15 Doug Rupp <rupp@gnat.com>
37648 * s-ctrl.ads: New file.
37650 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).
37652 * Make-lang.in: (GNAT_ADA_OBJS): Add ada/s-crtl.o.
37653 (GNATBIND_OBJS): Add ada/s-crtl.o.
37655 * Makefile.in [VMS]: Clean up ifeq rules.

37668 * Make-lang.in: Makefile automatically updated
37670 2003-12-11 Ed Falis <falis@gnat.com>
37672 * 5zinit.adb: Clean up.
37674 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37675 to __gnat_map_signal, imported from init.c to support
37676 signal -> exception mappings that depend on the vxWorks version.
37679 Created and exported __gnat_map_signal to support signal -> exception
37680 mapping that is dependent on the VxWorks version.

37690 __gnat_handler_installed, as done on all other platforms.
37691 Remove duplicated code.
37693 2003-12-11 Jerome Guitton <guitton@act-europe.fr>
37695 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
37697 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
37699 * sinfo.ads: Fix inconsistent example code in comment.
37701 2003-12-11 Robert Dewar <dewar@gnat.com>
37703 * a-tiinau.adb: Add a couple of comments
37705 * sem_ch3.adb: Minor reformatting
37708 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37709 Minor reformatting throughout
37711 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37713 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37714 bounds of a loop, create a separate block in order to generate proper
37715 cleanup actions to prevent memory leaks.
37717 * sem_res.adb (Resolve_Call): After a call to
37718 Establish_Transient_Scope, the call may be rewritten and relocated, in
37719 which case no further processing is needed.
37721 * sem_util.adb: (Wrong_Type): Refine previous fix.
37722 Fixes ACATS regressions.
37725 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37728 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37730 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37731 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37734 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37737 2003-12-08 Robert Dewar <dewar@gnat.com>
37739 * 7sintman.adb: Minor reformatting
37741 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37742 standard linker options to get standard libraries linked. We now plan
37743 to provide dummy versions of these libraries to match the appropriate
37744 configurable run-time (e.g. if a library is not needed at all, provide
37745 a dummy empty library).
37747 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37748 options (-L parameters and standard libraries). What we plan to do is
37749 to provide dummy libraries where the libraries are not required.
37751 * gnatbind.adb: Minor comment improvement
37753 2003-12-08 Javier Miranda <miranda@gnat.com>
37755 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37756 aggregate in the parent. Otherwise constants with limited aggregates
37757 are not supported. Add new formal to pass the component type (Ctype).
37758 It is required to call the corresponding IP subprogram in case of
37759 default initialized components.
37760 (Gen_Assign): In case of default-initialized component, generate a
37761 call to the IP subprogram associated with the component.
37762 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37763 of aggregate with default initialized components.
37764 (Has_Default_Init_Comps): Improve implementation to recursively check
37765 all the present expressions.
37767 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37768 to indicate that the initialization call corresponds to a
37769 default-initialized component of an aggregate.
37770 In case of default initialized aggregate with tasks this parameter is
37771 used to generate a null string (this is just a workaround that must be
37772 improved later). In case of discriminants, this parameter is used to
37773 generate a selected component node that gives access to the discriminant
37776 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37777 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37778 allocated aggregates with default-initialized components.
37780 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37781 the box notation is used in positional aggregates.

39521 2003-10-22 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
39523 * tracebak.c (MAX): Avoid redefinition warning.
39525 * init.c [sgi] (__gnat_error_handler): Remove i, unused.
39526 Change msg to const char *.
39527 (__gnat_install_handler): Remove ss, unused.
39528 [sun && __SVR4 && !__vxworks] (__gnat_error_handler): Change msg
39530 * cstreams.c (__gnat_full_name): Declare p only when used.
39531 (__gnat_full_name) [sgi] Return buffer.
39533 2003-10-22 Arnaud Charlet <charlet@act-europe.fr>
39535 * mingw32.h: New file.
39536 * gnat_wrapper.adb: New file.
39538 2003-10-22 Jerome Roussel <roussel@act-europe.fr>
39540 * g-regpat.ads, g-regpat.adb (Match): new function, to know if a
39541 string match a pre compiled regular expression (the corresponding
39542 version of the function working on a raw regular expression)
39543 Fix typos in various comments
39544 Update copyright notice in spec
39546 2003-10-21 Gary Dismukes <dismukes@gnat.com>
39549 (Component_Needs_Simple_Initialization): Return False when the type is a
39550 packed bit array. Revise spec comments to document this case.
39553 (Expand_Pragma_Import): Set any expression on the imported object to
39554 empty to avoid initializing imported objects (in particular this
39555 covers the case of zero-initialization of bit arrays).
39556 Update copyright notice.
39558 2003-10-21 Ed Schonberg <schonberg@gnat.com>
39561 (Load_Parent_Of_Generic): If parent is compilation unit, stop search,
39562 a subunit is missing.
39563 (Instantiate_Subprogram_Body): If body of function is missing, set type
39564 of return expression explicitly in dummy body, to prevent cascaded
39565 errors when a subunit is missing.
39569 (Access_Subprogram_Declaration): Verify that return type is valid.
39573 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39578 (Corresponding_Discriminant): If the scope of the discriminant is a
39579 private type without discriminant, use its full view.

41586 (general) Add @./@: where approriate, and two spaces after the
41587 full stop at the end of a sentence. Use @samp markup when
41588 referring concrete lexical entities (keywords, attribute names
41589 etc.), and @syntax for ARM grammar elements. Use @r for English

41604 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41605 function approach did not work well because of a side effect (the
41606 function call could reallocate the table which was being indexed
41607 using its result). Fixes ada/4851.

41666 Add 2001 to copyright date
41668 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41669 need to force universal inlining for these cases.

41885 When using a project file, fail if specified executable is relative
41886 path with directory information, and prepend executable, if not

41974 2001-12-17 Laurent Pautet <pautet@gnat.com>
41977 Fix comment of Shutdown_Socket and Close_Socket. These functions
41978 should not fail silently because if they are called twice, this
41979 probably means that there is a race condition in the user program.
41980 Anyway, this behaviour is consistent with the rest of this unit.
41981 When an error occurs, an exception is raised with the error message
41982 as exception message.
41984 2001-12-17 Robert Dewar <dewar@gnat.com>

43316 instead of the previous simple checksum algorithm.
43317 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43318 (Set_Source_Table): idem.
43321 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43322 instead of simple checksum.
43323 (CRC_Match): new function.
43324 (CRC_Error): new constant.
43326 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43327 a CRC now and not a simple checksum. A CRC uses lower-case hex
43328 letters, fixes ambiguity in parsing.
43330 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43331 is what this variable will store.
43333 * bcheck.adb: Change reference to chechsum in comments by CRC.
43334 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43335 rename All_Checksum_Match to All_CRC_Match. Change due to API
43336 renaming since now GNAT does not use a simple checksum but a
43337 CRC using GNAT.CRC32.
43339 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43340 now and not anymore a simple checksum.
43342 * lib-load.adb: Use Source_CRC instead of Source_Checksum in many

43379 * types.adb (Hex): Use lowercase for the letter part.
43381 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43382 for a word. This is currently used only for CRC. In previous version,
43383 the checksum was using a representation with all letter being
43384 upper-case. With the new implementation (using CRC) we do not remove
43385 the 32th bit of the CRC, so we can have an upper-case starting letter
43386 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43387 It is ambigous since the CRC was optional and could be followed by
43388 options like EB, EE. So now this routines uses lower-case letter for
43389 the hexadecimal representation. Strange enough only lower case letters
43390 where checked in Scan_ALI (even if this was not a possible case).
43392 * gnatvsn.ads (Library_Version): changed to 3.15a.
43394 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43397 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
