2029 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2030 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4125 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4126 convention from its base type, do not set the type to that of integer,

4191 the visible part of the spec of a remote types unit.

4193 New local subprogram Is_Valid_Remote_Object_Type, replaces
4194 Is_Recursively_Limited_Private.
4195 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4196 non-controlling formals (and the return type, even though this is not
4197 explicit in the standard) must support external streaming.

4199 as above for of RAS types and RCI subprograms. (The return type is not

4204 * sem_util.ads, sem_util.adb
4205 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4206 Is_Remote_Call_Interface to identify RACW types in a stable and
4207 consistent way. We used to rely in this predicate on the privateness of
4208 the designated type and its ancestors, but depending on the currently
4209 visible private parts, this caused false negatives. We now uniformly
4210 rely on checks made at the point where the RACW type is declared.

4224 Add missing escaping of all-caps word 'CPP' in error messages.
4225 (Build_Discriminated_Subtype): Do not inherit representation clauses
4226 from parent type if subtype already carries them, because they are
4227 inherited earlier during derivation and already include those that may
4228 come from a partial view.
4230 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4231 Check the declarations of a subprogram body for proper deferred

4265 (Add_One_Interp): Ignore any interpretation that is a primitive
4266 operation of an RACW stub type (these primitives are only executed
4267 through dispatching, never through static calls).
4268 (Collect_Interps): When only one interpretation has been found, set N's
4269 Entity and Etype to that interpretation, otherwise Entity and Etype may
4270 still refer to an interpretation that was ignored by Add_One_Interp,
4271 in which case would end up with being marked as not overloaded but with
4272 an Entity attribute not pointing to its (unique) correct interpretation.
4274 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4277 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4287 (Print_Itype): Do not modify the sloc of the component type of a
4288 (packed) array itype, because it is an unrelated type whose source
4289 location is independent of the point of creation of the itype itself.

4331 equivalent representation, but has the advantage of allowing
4332 compilation of this file under 64 bits platforms.

8532 WITH clause on a private sibling.
8533 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8534 child unit is a renaming, create an implicit with_clause on that

8637 perform subtype conformance between the formals of the current entry
8638 and those of the target interface primitive.
8639 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8640 Timed_Entry_Call): Analyze the triggering statement as the first step of
8641 the processing. If this is a dispatching select, postpone the analysis
8642 of all select statements until the Expander transforms the select. This

8644 replicated some of the select statements. In case the Expander is
8645 disabled, perform regular analysis.
8646 (Check_Triggering_Statement): New routine.
8647 (Analyze_Requeue): Exclude any interpretations that are not entries when
8648 checking overloaded names in a requeue. Also test type conformance for

8657 for the defaulted actual.
8659 2007-12-13 Geert Bosch <bosch@adacore.com>
8661 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9244 multiple inherited interfaces info. This information cannot be stored
9245 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9262 additional management on these nodes in Expand_Interface_Actuals.
9264 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9265 that handles use of 'Access and 'Unchecked_Access applied to

9311 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9312 used by VxWorks targets to have access to task-specific data and be
9313 able to extract the stack boundaries for stack checking.

9357 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9358 association for an access component, add an association with null as
9359 the expression. Remove testing for array subtypes and the setting in
9360 that case of Ctyp to the array component type, which prevented proper
9361 inclusion of an association for null-initialized arrays. Collapse
9362 condition that tests for array subtypes into just a test of
9363 Is_Partially_Initialized_Type (which already covers arrays anyway).

9380 * sem_ch4.adb: Minor code and comment reformatting.
9381 (Analyze_Allocator): When the designated type of an unconstrained
9382 allocator is a record with unknown discriminants or an array with

9517 type of file_info_ptr parameter.
9518 If mapped location support is enabled, create the isomorphic mapping
9519 between source files and line maps.
9520 (Sloc_to_locus): If mapped location support is enabled, translate
9521 source location into mapped location.
9522 (annotate_with_node): Rename into set_expr_location_from_node.

9549 Add a section on leap seconds control along with two entities used to
9550 enable and disable leap seconds support. The array Leap_Second_Times is
9551 now constant and contains hard time values pre-generated. Remove
9552 all elaboration code used to populate the table of leap seconds.
9555 Add entity Leap_Seconds_Support to the list of global run-time variables
9556 along with a comment on its usage and values.

9572 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9574 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9576 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9577 function which can be called by the debugger to interrupt the tasks of
9578 an Ada application asynchronously, as needed on VxWorks.

9612 2007-09-26 Javier Miranda <miranda@adacore.com>
9613 Eric Botcazou <ebotcazou@adacore.com>
9616 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9617 indirection added to the HT_Link component of the TSD. This is required
9618 to statically allocate the TSD.
9621 Minor reordering of the declarations in the private part. Required to
9622 add a level of indirection to the contents of the TSD component HT_Link.
9623 This is required to statically allocate the TSD.
9625 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9626 Is_Statically_Allocated set from constant objects.
9627 Do not make exported constants created by the compiler volatile.
9628 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9631 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9632 before returning them.
9634 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9635 public part of the package.
9636 (Make_DT): Move HT_Link component out of the TSD record. For this
9637 purpose Make_DT now declares a separate object that stores the
9638 HT_Link value, and initializes the TSD component with the address
9639 of this new object. The addition of this level of indirection is
9640 required to statically allocate the TSD because the TSD cannot
9641 have variable components.
9642 (Expand_Interface_Conversion): Improve the expanded code.
9643 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9645 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9646 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9647 if we are building static dispatch tables then we must not generate
9648 extra code to register the primitive because the dispatch table will
9649 be built at the end of the library package; otherwise we notify that
9650 we cannot build the static dispatch table.
9652 2007-09-26 Robert Dewar <dewar@adacore.com>
9654 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9669 for thunks associated with interface types.
9671 * einfo.ads: Improve documentatation of Is_Internal
9672 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9673 associated with interface types.
9674 Extensive comment fixes regarding flags that appear in all entities. The
9675 documentation is now consistent for all such flags (there were a number
9676 of errors in the documentation in this regard).
9678 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9680 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9681 of these procedures are passed a function call that already has
9682 build-in-place actuals (testing new flag
9683 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9684 the case where processing continues.
9685 (Expand_Call): If the call is generated from a thunk body then we
9686 propagate the extra actuals associated with the accessibility
9687 level of the access type actuals.
9689 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9690 of each extra formal of a protected operation to reference the
9691 corresponding extra formal of the subprogram denoted by the
9692 operation's Protected_Body_Subprogram.
9694 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9695 N_Function_Call nodes.
9697 2007-09-26 Robert Dewar <dewar@adacore.com>
9699 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9701 * debug.adb: Add d.s flag.
9703 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9705 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9706 debug variable so that it won't be initialized when pragma
9707 Initialize_Scalars is in effect.
9709 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9711 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9712 initialization of a full view. This is moved to
9713 Analyze_Package_Specification.
9715 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9716 preelaborable initialization of a full view in entity loop.
9717 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9718 its child units are use-visible only if they are visible child units.
9720 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9721 whether an expression can be used within a type declaration that
9722 requires preelaborable init.
9723 (Check_Components): Replace inline code that does partial checking for
9724 preelaborable default expressions with call to
9725 Is_Preelaborable_Expression.
9726 (Has_Preelaborable_Initialization): In the case of a generic actual
9727 subtype, (that is, Is_Generic_Actual is True), return the result of
9728 applying Has_Preelaborable_Initialization to the generic actual's base
9731 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9733 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9734 call to Jan_1_Day _Of_Week to optimize its performance.
9735 (Is_Leap): Move the routine to the scope of Week_In_Year.
9736 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9737 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9738 avoids calling Time_Of and Split, thus making it more efficent.
9739 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9741 * g-calend.ads (Week_In_Year): Change comment to reflect new
9744 2007-09-26 Emmanuel Briot <briot@adacore.com>
9746 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9747 Command_Line): New types
9748 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9749 support for defining how switches can be grouped on a command line (as
9750 is the case for -gnatw... for GNAT), and how simple switches can be
9751 used as aliases for more complex switches (-gnatwa is same as
9753 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9754 (Start, Current_*): New subprograms
9755 Added support for parsing an array of strings in addition to the real
9757 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9758 be moved from the body to the private part of the spec.
9759 (*): All subprograms now have an extra parameter with default value to
9760 specify which parser should be used. For backward compatibility, it
9761 defaults to parsing the command line of the application. They were also
9762 modified to properly handle cases where each of the argument does not
9763 start at index 1 (which is always true for Ada.Command_Line, but not
9764 when processing any Argument_List).
9765 (Free): New subprogram
9766 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9767 Argument): New subprograms
9768 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9769 special characters like ':', '=',... are now handled in a single place,
9770 which makes the code more extensible eventually.
9771 (Getopt, Full_Switch): When the switch was returned as part of the
9772 special character '*', make sure it is prepended by the switch character
9773 ('-' in general), so that the application knows whether "foo" or "-foo"
9774 was specified on the command line.
9776 2007-09-26 Florian Villoing <villoing@adacore.com>
9778 * g-dirope.adb (Remove_Dir): In case we are removing directories
9779 recursively, make sure that if an exception is raised during the
9780 processing, the current working directory is reset to its initial
9781 value before propagating the exception.
9783 2007-09-26 Vincent Celier <celier@adacore.com>
9785 * gnatbind.adb: If there are several ALI files specified and there is
9786 a main program to bind, the first ALI is expected to contain the main
9787 subprogram and the names of the binder generated files will be derived
9788 from the first ALI file name.
9789 (Gnatbind): Fix insertion character in invocation of Error_Msg
9791 2007-09-26 Vincent Celier <celier@adacore.com>
9793 * gnatcmd.adb (Check_Files): Do not include sources that have been
9794 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9796 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9798 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9799 information about each of its index types, following the type
9800 reference for its component type.
9802 2007-09-26 Vincent Celier <celier@adacore.com>
9804 * make.adb: (Kill): New procedure (__gnat_kill imported)

9811 sources, so that the correct paths will be found.
9813 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9815 2007-09-26 Vincent Celier <celier@adacore.com>
9817 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9819 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9820 Replace components Compiler_Min_Options and Binder_Min_Options with
9821 Compiler_Required_Switches and Binder_Required_Switches in record
9823 Remove components Default_Language and Config in Project_Tree_Data,
9826 * prj-attr.adb: New attributes Required_Switches (<language>) in
9827 packages Compiler and Binder.
9829 * prj-nmsc.adb: Major rewrite of the processing of configuration
9830 attributes for gprbuild. No impact on GNAT tools.

9864 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9866 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9867 ancestor of the derived type, the operations are inherited from the
9868 primary dispatch table of the parent.
9869 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9870 when the context is an explicit type conversion.
9872 2007-09-26 Ed Schonberg <schonberg@adacore.com>

9917 no sources, but is an extending project.
9919 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9921 * trans.c: Fix misplaced #define.

10172 potentially be called.
10173 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10174 body for 'Output when the type is abstract (only the creation of the
10175 body for 'Input is excluded when the type is abstract).

10177 statement, so that False will be returned for TTS_Stream_Input if the
10178 associated tagged type is an abstract extension. Add comments for
10180 (Expand_N_Object_Declaration): For the case of a shared passive
10181 variable, insert init proc call only after the shared variable
10182 procedures have been processed, because the IP call needs to undergo
10183 shared passive variable reference expansion, which requires these

10196 type, retrieve its value from the aggregate itself, where it must have
10199 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10200 to remove other spurious ambiguities on arithmetic operations involving
10201 literals and addresses, on systems where Address is a visible integer
10202 type, when the operator is called in functional notation.
10203 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10204 is legal when the types match, even if the operation is currently
10207 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10209 * sem_ch12.adb (Build_Local_Package): A formal package with no
10210 associations is legal if all formals have defaults. It is not

10322 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10324 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10330 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10331 spurious ambiguities when integer literals appear in the context of an
10332 address type that is a visible integer type.
10334 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10335 exceptions never being raised.
10336 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10352 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10353 library-level package renaming, pass the declaration associated with
10354 the renaming's special debug variable to Qualify_Entity_Names to ensure
10355 that its encoded name is properly qualified.
10357 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10358 occurring in the list of entities to qualify, and do not attempt to
10359 traverse an entity list in that case. Variables associated with
10360 ` library-level package renamings can now occur in the table.
10362 * exp_dbug.ads: Revise documentation of the encoding for renaming

10368 access type points to an unconstrained array.
10370 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10372 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10375 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

10384 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10385 concatenations of string literals into a single literal, in order to
10386 avoid very deep recursion in the front end, which was causing stack
10389 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10390 string, and the right operand is a string literal (the case of "" &
10391 "..."), optimize by avoiding copying the right operand -- just use the
10392 value of the right operand directly.
10394 * stringt.adb (Store_String_Chars): Optimize by growing the
10395 String_Chars table all at once, rather than appending characters one by
10397 (Write_String_Table_Entry): If the string to be printed is very long,
10398 just print the first few characters, followed by the length. Otherwise,
10399 doing "pn(n)" in the debugger can take an extremely long time.
10401 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10402 Store_String_Char with Store_String_Chars.

10415 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10416 clauses of subunits, ignore limited_with_clauses that are illegal and
10417 have not been fully analyzed.
10419 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10421 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10422 flag, for effiency. It is called when analyzing arithmetic operators
10423 and also for actuals in calls that are universal_integers. The flag is
10424 set for the predefined type address, and for any type or subtype
10427 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10428 Universal_Integer, when the formal is a descendent of address and the
10429 call appears in user code.
10430 (Analyze_Selected_Component): if the prefix is a private extension, the
10431 tag component is visible.

10496 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10497 associated with Standard_Debug_Renaming_Type, to be used as the type of
10498 the special variables whose names provide debugger encodings for
10499 renaming declarations.
10501 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10502 (Set_Debug_Renaming_Link): Change to set Node25.

10509 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10510 and literal with creation of a variable of type
10511 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10512 and the entity of the renaming declaration.
10513 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10514 part of the name of a variable that has a Debug_Renaming_Link.
10516 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10517 special type to be associated with variables that provide debugger

10521 Ed Schonberg <schonberg@adacore.com>
10522 Javier Miranda <miranda@adacore.com>
10524 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10525 ancestor part given by an aggregate to test for an unchecked conversion,
10526 since this can occur in some cases when the ancestor part is a function
10527 call, and we don't want to fall into the recursive call to this
10528 procedure in that case.
10530 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10531 stream attributes on limited types to account for user-specified
10532 attributes as well as whether Input (resp. Output) becomes available
10533 due to Read (resp. Write) being available for the type. Change Boolean
10534 variable to the more accurate name
10535 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10536 double-"not" predicate at beginning of return statement to more
10537 understandable form.
10539 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10540 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10541 in a block statement and use that as the first statement of the
10542 expanded return rather than incorrectly using the handled sequence as
10543 the first statement.
10545 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10546 operation, generate an explicit freeze node for it rather than
10547 generating extra formals, to ensure that gigi has the proper order of
10548 elaboration for anonymous subtypes in the signature of the subprograms.
10549 (Build_In_Place_Formal): Move assertion to beginning of loop.
10550 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10553 applied to a function call (occurs for some cases of 'Input).
10555 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10556 2005, generate an extended return statement enclosing the result object
10559 * freeze.adb (Freeze_Record_Type): Extend the current management of
10560 components that are access type with an allocator as default value: add
10561 missing support to the use of qualified expressions of the
10562 allocator (which also cause freezing of the designated type!)
10563 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10564 dispatching operation, since extra formals may be needed by calls to
10565 build-in-place functions (such as stream 'Input).
10567 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10568 formals for 'Constrained and accessibility level in the case of a
10569 predefined dispatching operation.
10571 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10572 point, no need to find the parent node.
10574 2007-08-16 Javier Miranda <miranda@adacore.com>
10576 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10577 and entry barriers.
10579 2007-08-16 Javier Miranda <miranda@adacore.com>
10581 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10582 is not really required and can introduce regression with the debugger.
10583 The original problem is fixed with the patch written for checks.adb.
10585 2007-08-16 Thomas Quinot <quinot@adacore.com>
10587 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10597 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10598 parameter Including_Non_Switch, defaulted to True. When
10599 Including_Non_Switch is False, options that are not switches and
10600 appear as relative path are not converted to absolute paths.
10602 2007-08-16 Nicolas Roche <roche@adacore.com>
10604 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10615 from the immediate ancestor of Main_Unit_Entity.
10616 (Install_Limited_Withed_Unit): Do not install the limited view of
10617 package P if P is reachable through an ancestor chain from package C
10618 and C also has a with clause for P in its body.

10620 (Has_With_Clause): New routine.
10622 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10624 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10625 generic for an enclosing instance is a global reference, even though
10626 its scope is the enclosing instance.
10628 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10629 Javier Miranda <miranda@adacore.com>
10631 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10632 initialize a limited object.

10637 2007-08-16 Robert Dewar <dewar@adacore.com>
10639 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10642 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10644 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10645 implements an operation inherited from a progenitor interface, verify
10646 that they are subtype-conformant.
10648 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10649 Bob Duff <duff@adacore.com>
10650 Nicolas Setton <setton@adacore.com>
10652 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10653 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10654 the statement which is being resolved comes from a predefined library
10655 unit, all non-predefined library interpretations are skipped.
10656 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10657 but the "&" is user defined, give an error, because the folding would
10660 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10661 the parser has folded a long sequence of concatenations of string
10664 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10665 and "JMP_BUF" variables as artificial.
10666 (N_String_Literal): Do not use alloca for very long string literals. Use

10714 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10715 Suppress unmodified in-out parameter warning in some cases
10716 This patch is a also fairly significant change to the way suppressible
10717 checks are handled.
10719 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10720 needed for access to concurrent record types generated by the expander.
10721 (Generate_Range_Check): When generating a temporary to capture the
10722 value of a conversion that requires a range check, set the type of the
10723 temporary before rewriting the node, so that the type is always
10724 properly placed for back-end use.
10725 (Apply_Float_Conversion_Check): Handle case where the conversion is
10727 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10744 parameters when deciding whether to apply a run-time accessibility
10746 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10747 aggregate code before allocator, and ahead of declaration for
10748 temporary, to prevent access before elaboration when the allocator is
10749 an actual for an access parameter.
10750 (Expand_N_Type_Conversion): On an access type conversion involving an
10751 access parameter, do not apply an accessibility check when the
10752 operand's original node was an attribute other than 'Access. We now
10753 create access conversions for the expansion of 'Unchecked_Access and
10754 'Unrestricted_Access in certain cases and clearly accessibility should
10755 not be checked for those.
10757 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10758 includes a type conversion of a packed component that has been expanded,
10759 recover the original expression for the object, and use this expression
10760 in the post-call assignment statement, so that the assignment is made
10761 to the object and not to a back-end temporary.
10762 (Freeze_Subprogram): In case of primitives of tagged types not defined
10763 at the library level force generation of code to register the primitive
10764 in the dispatch table. In addition some code reorganization has been
10765 done to leave the implementation clear.
10766 (Expand_Call): When expanding an inherited implicit conversion,
10767 preserve the type of the inherited function after the intrinsic
10768 operation has been expanded.
10770 * exp_ch2.ads, exp_ch2.adb
10771 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10772 of an entry formal appearing in an assignment statement does not assign
10774 (Expand_Current_Value): Instead of calling a routine to determine
10775 whether the prefix of an attribute reference should be optimized or
10776 not, prevent the optimization of such prefixes all together.
10778 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10779 component whose prefix is known to be of an access type is an implicit
10780 dereference and does not assign to the prefix.
10782 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10783 Robert Dewar <dewar@adacore.com>
10785 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10786 itype is visited, make an entry into table to link associated node and
10788 Add comments and correct harmless error in Build_NCT_Hash_Tables
10789 (Array_Aggr_Subtype): Associate each itype created for an index type to
10790 the corresponding range construct, and not to the aggregate itself. to
10791 maintain a one-to-one correspondence between itype and its associated
10792 node, to prevent errors when complex expression is copied.
10793 Fix mishandling of multiple levels of parens
10795 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10796 treatment of limited views uniform for all visible declarations in a
10797 limited_withed package.
10798 (New_Copy_Tree): If hash table is being used and itype is visited,
10799 make an entry into table to link associated node and new itype.
10800 (Resolve_Record_Aggregate): Do not add an others box association for a

10851 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10852 generation of a freezing node to ensure proper management of null
10853 excluding access types in the backend.
10854 (Create_Extra_Formals): Test base type of the formal when checking for
10855 the need to add an extra accessibility-level formal. Pass the entity E
10856 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10857 originally being done in a couple of cases), to ensure that the
10858 Extra_Formals list gets set on the entity E when the first entity is
10860 (Conforming_Types): Add missing calls to Base_Type to the code that
10861 handles anonymous access types. This is required to handle the
10862 general case because Process_Formals builds internal subtype entities
10863 to handle null-excluding access types.
10864 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10865 functions that need it, even when not marked Requires_Overriding.
10866 Improve warnings for in out parameters
10867 (Analyze_Function_Return): Warn for disallowed null return
10868 Warn on return from procedure with unset out parameter
10869 Ensure consistent use of # in error messages
10870 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10871 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10872 the implicit conversion of the expression done for anonymous access
10873 types. This is required to generate the code of the null excluding
10874 check (if required).
10876 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10877 A formal parameter is never publicly referenceable outside of its body.
10878 (Check_References): For an unreferenced formal parameter in an accept
10879 statement, use the same warning circuitry as for subprogram formal
10881 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10882 Output_Unreferenced_Messages, containing the part of that routine that
10883 is now reused for entry formals as described above.
10884 (Goto_Spec_Entity): New function
10885 (Check_References): Do not give IN OUT warning for dispatching operation
10886 Improve warnings for in out parameters

10893 Javier Miranda <miranda@adacore.com>
10894 Gary Dismukes <dismukes@adacore.com>
10896 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10897 (Expand_N_Attribute_Reference): Further unify the handling of the
10898 three forms of access attributes, using common code now for all three
10899 cases. Add a test for the case of applying an access attribute to
10900 an explicit dereference when the context is an access-to-interface
10901 type. In that case we need to apply the conversion to the prefix
10902 of the explicit dereference rather than the prefix of the attribute.
10903 (Attribute_Version, UET_Address): Set entity as internal to ensure
10904 proper dg output of implicit importation.
10905 (Expand_Access_To_Type): Removed.
10906 (Expand_N_Attribute_Reference): Merge the code from the three cases
10907 of access attributes, since the processing is largely identical for
10908 these cases. The substantive fix here is to process the case of a
10909 type name prefix (current instance case) before handling the case
10910 of interface prefixes.

10915 Robert Dewar <dewar@adacore.com>
10917 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10918 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10919 type that is an anonymous access to controlled object, establish
10920 an associated finalization chain to avoid corrupting the global
10921 finalization list when a dynamically allocated object designated
10922 by such a component is deallocated.
10923 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10924 functions that need it, even when not marked Requires_Overriding.
10925 (Initialize_Tag): Replace call to has_discriminants by call to
10926 Is_Variable_Size_Record in the circuitry that handles the
10927 initialization of secondary tags.
10928 (Is_Variable_Size_Record): New implementation.
10929 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10930 Suppress_Initialization pragma for a derived type.
10931 (Is_Variable_Size_Record): New subprogram.
10932 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10933 initial version of this routine and also fixes problems causing
10934 incomplete initialization of the table of interfaces.
10935 (Build_Init_Procedure): Improve the generation of code to initialize the
10936 the tag components of secondary dispatch tables.
10937 (Init_Secondary_Tags): New implementation that simplifies the previous
10938 version of this routine.
10939 (Make_DT): Add parameter to indicate when type has been frozen by an
10940 object declaration, for diagnostic purposes.
10941 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10942 diagnose attemps to freeze a subprogram when some untagged type of its
10943 profile is a private type whose full view has not been analyzed yet.
10944 (Freeze_Array_Type): Generate init proc for packed array if either
10945 Initialize or Normalize_Scalars is set.
10946 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10947 constructing the new profile, copy the null_exclusion indicator for each
10948 parameter, to ensure full conformance of the new body with the spec.
10950 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10951 Create wrappers for constructor functions that need it, even when not
10952 marked Requires_Overriding.
10953 (Covers): Handle properly designated types of anonymous access types,
10954 whose non-limited views are themselves incomplete types.
10955 (Add_Entry): Use an entity to store the abstract operation which hides
10957 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10958 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10959 initialization aggregate.
10960 (Function_Interp_May_Be_Hidden): Rename to
10961 Function_Interp_Has_Abstract_Op.
10962 (Has_Compatible_Type): Remove machinery that skips interpretations if
10963 they are labeled as potentially hidden by an abstract operator.
10964 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10965 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10966 (Write_Overloads): Output the abstract operator if present.
10967 (Add_Entry): Before inserting a new entry into the interpretation table
10968 for a node, determine whether the entry will be disabled by an abstract

10971 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10973 (Function_Interp_May_Be_Hidden): New routine.
10974 (Has_Compatible_Type): Do not consider interpretations hidden by
10975 abstract operators when trying to determine whether two types are
10977 (Has_Hidden_Interp): New routine.
10978 (Set_May_Be_Hidden_Interp): New routine.
10979 (Write_Overloads): Write the status of flag May_Be_Hidden.

10985 types declared in the declarative part of a nested package body or in
10986 the proper body of a stub.
10987 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10988 of the same dispatch table slot to renamed primitives.
10989 (Make_Select_Specific_Data_Table): Handle private types.
10990 (Tagged_Kind): Handle private types.
10991 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10992 output of implicit importation and exportation.
10993 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10994 first formal of the thunk is always associated with the controlling
10995 type. In addition perform the following code cleanup: remove formal
10996 Thunk_Alias which is no longer required, cleanup evaluation of the
10997 the controlling type, and update the documentation.
10998 Replace occurrence of Default_Prim_Op_Count by
10999 Max_Predef_Prims. Addition of compile-time check to verify
11000 that the value of Max_Predef_Prims is correct.
11001 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11002 (Make_DT): Add parameter to indicate when type has been frozen by an
11003 object declaration, for diagnostic purposes.
11004 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11005 construction of statically allocated dispatch tables.
11006 (Make_DT): In case of library-level tagged types export the declaration
11007 of the primary tag. Remove generation of tags (now done by Make_Tags).
11008 Additional modifications to handle non-static generation of dispatch
11009 tables. Take care of building tables for asynchronous interface types
11010 (Make_Tags): New subprogram that generates the entities associated with
11011 the primary and secondary tags of Typ and fills the contents of Access_
11012 Disp_Table. In case of library-level tagged types imports the forward
11013 declaration of the primary tag that will be declared later by Make_DT.
11014 (Expand_Interface_Conversion): In case of access types to interfaces
11015 replace an itype declaration by an explicit type declaration to avoid
11016 problems associated with the scope of such itype in transient blocks.

11019 Ed Schonberg <schonberg@adacore.com>
11020 Javier Miranda <miranda@adacore.com>
11022 * exp_util.ads, exp_util.adb:
11023 This patch replaces a number of occurrences of explicit tests for N_Null
11024 with calls to Known_Null. This improves tracking of null values, since
11025 Known_Null also catches null constants, and variables currently known to
11026 be null, so we get better tracking.
11027 (Ensure_Defined): create an itype reference only in the scope of the
11029 (Side_Effect_Free): A selected component of an access type that
11030 denotes a component with a rep clause must be treated as not
11031 side-effect free, because if it is part of a linked structure its
11032 value may be affected by a renaming.
11033 (Expand_Subtype_From_Expr): For limited objects initialized with build
11034 in place function calls, do nothing; otherwise we prematurely introduce
11035 an N_Reference node in the expression initializing the object, which
11036 breaks the circuitry that detects and adds the additional arguments to
11037 the called function. Bug found working in the new patch for statically
11038 allocated dispatch tables.
11039 (Is_Library_Level_Tagged_Type): New subprogram.
11040 (Remove_Side_Effects): If the expression of an elementary type is an
11041 operator treat as a function call.
11042 (Make_Literal_Range): If the index type of the array is not integer, use
11043 attributes properly to compute the constraint on the resulting aggregate
11046 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11047 class-wide type whose base type is an incomplete private type, leave
11048 class-wide type unfrozen so that freeze nodes can be generated
11049 properly at a later point.
11050 (Freeze_Entity, array case): Handle case of pragma Pack and component
11051 size attributre clause for same array.

11108 attribute Body in package Naming. Do not replace a source/unit in the
11109 same project when the order of the source dirs are known. Detect
11110 duplicate sources/units in the same project when the order of the
11111 source dirs are not known.
11112 (Check_Ada_Name): Allow all identifiers that are not reserved words
11114 Major update of the Project Manager and of the project aware tools,

11118 directory of non extending project to nil.
11119 Change type of path name variables to be Path_Name_Type
11120 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

11725 (Complete_Object_Operation): If actual has an access type and
11726 controlling formal is not an in_parameter, reject the actual if it is
11727 an access_to_constant type.
11728 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11729 type, the candidate operations are found in the scope of declaration of
11730 the type, because the type has no primitive subprograms.
11731 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11732 a private extension, only examine visible components before trying to
11733 analyze as a prefixed call.
11734 Change Entity_List to Type_To_Use, for better readability.

11747 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11748 purpose of enforcing E.2.2(8) only if it is not available at any place.
11749 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11750 when checking the legality of an extension aggregate in a preelaborable
11751 package. Treat the literal null as a valid default expression in a
11752 component declaration for a type with preelaborable initialization.
11753 A limited interface is a legal progenitor for the designated type of a
11754 remote access to class-wide type.

11787 (Resolve_Actuals): When verifying that an access to class-wide object
11788 is an actual for a controlling formal, ignore anonymous access to
11789 subprograms whose return type is an access to class_wide type.
11790 (Resolve_Slice): If the prefix of the slice is a selected component
11791 whose type depends on discriminants, build its actual subtype before
11792 applying range checks on the bounds of the slice.
11793 (Valid_Conversion): In an instance or inlined body, compare root types,
11794 to prevent anomalies between private and public views.

13007 prefix if the prefix has a synchronized type and the type of the formal
13008 is its corresponding record, as can be the case when the primitive
13009 operation is declared outside of the body of the type.
13010 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13011 perform homonym traversal, looking for class-wide operation matches
13012 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13013 access parameters are now restricted to anonymous access types.
13014 (Mark_Allocator): An allocator with a discriminant association parent is
13016 (Try_One_Prefix_Interpretation): If the type of the object is
13017 incomplete, as can be happen when it is a limited view obtained through
13018 a limited_with_clause, the selected component is not part of a prefixed
13020 (Complete_Object_Operation): Diagnose properly an object that is not
13021 aliased when the corresponding controlling formal is an access
13023 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13024 ambiguous calls in prefixed notation, where two primitives differ only
13025 in that the controlling argument of one is an access parameter.
13027 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13028 whether a function that returns an unconstrained type can be inlined.
13029 (Process_Formals): Diagnose properly the illegal use of an incomplete
13030 type in the profile of an access_to_subprogram declaration.
13031 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13032 operations are attached to the corresponding record.
13033 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13034 When processing a primitive of a concurrent type which implements an
13035 interface change the type of all controlling formals to that of the
13036 corresponding record type.
13037 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13038 to determine the tagged type to which a primitive belongs.
13039 (Check_Conventions): Capture condition to ignore a primitive operation
13040 (which is shared between the loop in Check_Conventions and the one in
13041 Check_Convention) in a new local function Skip_Check.
13042 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13043 confusion with Check_Conventions' own Prim_Op local variable.
13044 (Create_Extra_Formals): Test for a tagged result type rather than a
13045 controlling result when determining whether to add a BIP_Alloc_Form
13046 formal and a BIP_Final_List formal to the function.
13047 (Check_Conformance); For parameters that are anonymous access types,
13048 subtype conformance requires that the not null and the constant
13049 indicators must match
13050 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13051 to retrieve the appropriate type when processing a concurrent type
13052 declared within a generic. Minor comment reformatting. Change invocation
13053 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13055 (Analyze_Subprogram_Body): If the return type of a function is an
13056 anonymous access to the limited view of a class-wide type, and the
13057 non-limited view of the type is available, update the type of the
13058 function so that code can be generated.
13059 (Process_Formals): In case of access-subtype itype whose designated
13060 type is also an itype (situation that happens now with access to
13061 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13062 attribute to avoid backend problems.
13063 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13064 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13065 anonymous types' designated types are same before testing
13066 Subtypes_Statically_Match.
13067 (Create_Extra_Formals): Test for a named access parameter that is a
13068 controlling formal as an additional condition for adding an
13069 accessibility level formal. This can occur in the subp type created for
13070 dispatching calls in Expand_Dispatching_Call, and allows calling
13071 Create_Extra_Formals from that procedure rather than special-casing the
13072 extra formals there.
13073 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13074 when the function has a controlling result.
13075 (Check_Returns): Add much more knowledge of the optimization of local
13076 raise statements to gotos, to retain proper warnings in this case.
13077 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13078 nodes when looking for last statement.
13080 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13081 class-wide types visible through limited with clauses.
13082 (Add_One_Interp): If the operands are anonymous access types, the
13083 predefined operator on universal_access is immediately visibles
13084 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13085 other anonymous access types.
13086 (Disambiguate): Take into account CIL convention.
13087 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13089 2007-06-06 Robert Dewar <dewar@adacore.com>
13091 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13092 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13093 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13094 Fix lower bound of tables.
13097 * nlists.adb: Ditto.
13098 (Prev_Node, Next_Node): Change index type to Int so that it properly
13099 covers the range First_Node_Id - 1 up.
13101 2007-06-06 Javier Miranda <miranda@adacore.com>
13102 Ed Schonberg <schonberg@adacore.com>
13103 Bob Duff <duff@adacore.com>
13104 Hristian Kirtchev <kirtchev@adacore.com>
13106 * exp_aggr.ads, exp_aggr.adb:
13107 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13108 in extension aggregates.
13109 (Flatten): Other conditions being met, an aggregate is static if the
13110 low bound given by component associations is different from the low
13111 bound of the base index type.
13112 (Packed_Array_Aggregate_Handled): If the component type is itself a
13113 packed array or record, the front-end must expand into assignments.
13114 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13115 Init_Pr, instead of Ancestor_Is_Expression.
13116 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13117 coextension chain root, either generate a list controller or use the
13118 already existing one.
13119 (Static_Array_Aggregate): New procedure to construct a positional
13120 aggregate that can be handled by the backend, when all bounds and
13121 components are compile-time known constants.
13122 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13123 types covering interface types into assignments.
13124 (Replace_Type): move to Build_Record_Aggr_Code.
13125 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13126 interface type, convert to the definite type of the aggregate itself,
13127 so that needed components are visible.
13128 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13129 components and the context is an extended return statement do not
13130 create a transient block for it, to prevent premature finalization
13131 before the return is executed.
13132 (Gen_Assign): Do not generate a call to deep adjust routine if the
13133 component type is itself an array of controlled (sub)-components
13134 initialized with an inner aggregate.
13135 (Component_Check): New name for Static_Check. This name is now more
13136 appropriate, and documentation is added which was missing.
13137 (Component_Check): Add test for bit aligned component value
13138 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13139 Tagged_Comps, name is more appropriate given added function below.
13140 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13142 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13143 Javier Miranda <miranda@adacore.com>
13144 Robert Dewar <dewar@adacore.com>
13146 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13147 Terminated: Add unchecked type conversion from System.Address to
13148 System.Tasking.Task_Id when calling the predefined primitive
13150 Disable new Ada 05 accessibility check for JVM.NET targets, which
13151 cannot be implemented in a practical way.
13152 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13153 the sources always references the tag of the actual object. Therefore,
13154 if 'Tag is applied in the sources to class-wide interface objects we
13155 generate code that displaces "this" to reference the base of the object.
13156 (Expand_N_Attribute_Reference, case Size): Return specified size if
13157 known to front end.
13158 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13159 has code that displaces the pointer of the object to manage interface
13160 types. However this code must not be executed when the prefix is a
13161 subprogram. This bug caused the wrong expansion of the internally
13162 generated assignment that fills the dispatch table when the primitive
13163 is a function returning a class-wide interface type.
13164 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13165 Set_Attribute_Name for Name_Unaligned_Valid.
13167 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13168 Gary Dismukes <dismukes@adacore.com>
13170 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13171 If the initialization is the equivalent aggregate of the initialization
13172 procedure of the type, do not remove it.
13173 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13174 initialized to null from having their expression reset to empty and
13175 note this exception in the comment.
13177 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13178 Robert Dewar <dewar@adacore.com>
13179 Ed Schonberg <schonberg@adacore.com>
13180 Gary Dismukes <dismukes@adacore.com>
13182 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13183 Add "with" and "use" clauses for Sem_Attr.
13184 (Expand_Current_Value): Do not replace occurences of attribute
13185 references where the prefix must be a simple name.
13187 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13188 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13189 Attribute_Requires_Simple_Name_Prefix.
13190 (Name_Modifies_Prefix): Body of new function.
13191 (Requires_Simple_Name_Prefix): Body of new function.
13192 (Resolve_Attribute, case Access): Improve error message for case of
13193 mismatched conventions.
13194 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13196 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13197 constrained subtype for a nominal unconstrained type, use its base type
13198 to check for conformance with the context.
13199 (Resolve_Attribute): Remove test of the access type being associated
13200 with a return statement from condition for performing accessibility
13201 checks on access attributes, since this case is now captured by
13202 Is_Local_Anonymous_Access.
13203 (Analyze_Access_Attribute): Set Address_Taken on entity
13204 (Analyze_Attribute, case Address): Set Address_Taken on entity
13205 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13206 validating an access attribute whose prefix is a current instance.
13207 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13208 applied to dispatching operations, if freezing is required then we set
13209 the attribute Has_Delayed_Freeze in the prefix's entity.
13210 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13211 current scope if access of local subprogram taken
13212 (Analyze_Access_Attribute): Check legality of self-reference even if the
13213 expression comes from source, as when a single component association in
13214 an aggregate has a box association.
13215 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13216 the prefix if it is a protected operation and the attribute is
13217 Unrestricted_Access.
13218 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13219 reference to the base type of the context, to force a constraint check
13220 when the context is an access subtype with an explicit constraint.
13221 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13222 node is rewritten as an interface conversion. leave unanalyzed after
13223 resolution, to ensure that type checking against the context will take

13227 Javier Miranda <miranda@adacore.com>
13228 Robert Dewar <dewar@adacore.com>
13230 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13231 wrapper when the full view of the controlling type of an inherited
13232 function that dispatches on result implements interfaces.
13233 (Expand_N_Object_Declaration): In cases where the type of the
13234 declaration is anonymous access, create finalization list for it.
13235 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13236 if the object has no explicit initialization, to match description of
13237 functionality of pragam Persistent_BSS.
13238 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13239 new function to build static aggregates, to replace initialization call
13240 when static initialization is desired.
13241 (Freeze_Type): Generate a list controller for an access type whenever
13242 its designated type has controlled anonymous access discriminants.
13243 (Build_Equivalent_Aggregate): New procedure to compute a static
13244 aggregate to be used as default initialization for composite types,
13245 instead of a generating a call to the initialization procedure for the
13247 (Build_Initialization_Call): When available, replace a call to the
13248 initialization procedure with a copy of the equivalent static aggregate
13250 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13251 declarations for objects of a class-wide interface type, rather than
13252 just identifiers, to prevent visibility problems.
13253 (Expand_N_Object_Declaration): When expanding the declaration for an
13254 object of a class-wide interface type, preserve the homonym chain of
13255 the original entity before exchanging it with that of the generated
13256 renaming declaration.
13257 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13258 active, because there is no way to handle the exception.
13259 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13260 to do a minimum decoration of the Access_Disp_Table list.
13261 (Expand_Record_Controller): Avoid the addition of the controller between
13262 the component containing the tag of a secondary dispatch table and its
13263 adjacent component that stores the offset to the base of the object.
13264 This latter component is only generated when the parent type has
13265 discriminants ---documented in Add_Interface_Tag_Components).
13266 (Apply_Array_Size_Check): Removed, no longer needed.
13267 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13268 components, create a Master_Entity for it only if it contains tasks.
13269 (Build_Init_Procedure): Suppress the tag assignment compiling under
13271 (Freeze_Record_Type): Remove code associated with creation of dispatch
13273 (Init_Secondary_Tags): Update type of actuals when generating calls to
13274 Ada.Tags.Set_Offset_To_Top
13275 (Stream_Operation_OK): Disable use of streams compiling under no
13277 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13278 if Has_Init_Expression set.
13279 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13280 Register_Primitive, which provides the same functionality.
13281 (Requires_Init_Proc): Return false in case of interface types.
13282 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13284 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13285 is always associated with a predefined primitive because the internal
13286 entities associated with interface types are not predefined primitives.
13287 Therefore, the call to Is_Internal is replaced by a call to the
13288 function Is_Predefined_Dispatching_Operation.
13289 (Make_Eq_If): When generating the list of comparisons for the
13290 components of a given variant, omit the controller component that is
13291 present if the variant has controlled components.
13293 2007-06-06 Javier Miranda <miranda@adacore.com>
13294 Hristian Kirtchev <kirtchev@adacore.com>
13295 Bob Duff <duff@adacore.com>
13297 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13298 handle the creation of finalization lists and calls for nested
13299 coextensions when the root of the chains is part of a return statement.
13300 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13302 (Expand_Record_Equality): Skip components that are interface types.
13303 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13304 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13305 with Rewrite_Coextension. Change the condition for detecting coextension
13307 (Is_Local_Access_Discriminant): Removed.
13308 (Rewrite_Coextension): New routine which rewrites a static coextension
13309 as a temporary and uses its unrestricted access in the construction of
13311 (Complete_Coextension_Finalization): New routine. Generate finalization
13312 attachment calls to all delayed coextensions.
13313 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13314 the allocator is not a coextension itself and has delayed coextensions.
13315 If the current allocator is controlled, but also a coextension, delay
13316 the generation of the finalization attachment call.
13317 Rename local variable "Node" to "Nod" in order to avoid confusion with
13319 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13320 limited types that are not inherently limited. Such an allocator is
13321 illegal, but is generated by the expander for a return statement, to
13322 copy the result onto the secondary stack. This is the only case where a
13323 limited object can be copied. Generate code to displace the pointer
13324 to the object if the qualified expression is a class-wide interface
13325 object. Such displacement was missing and hence the copy of the object
13327 (Apply_Accessibility_Check): Handle allocated objects initialized in
13329 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13330 and Expand_Allocator_Expression. Allocating class-wide interface objects
13331 this routine displaces the pointer to the allocated object to reference
13332 the component referencing the corresponding secondary dispatch table.
13333 Expand_Allocator_Expression): Add missing support to allocate class-wide
13334 interface objects initialized with a qualified expression.
13335 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13336 function result type, and use the finalization list associated with the
13337 function scope in that case (such an anonymous type should not be
13338 treated like an access parameter's type).
13340 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13341 Gary Dismukes <dismukes@adacore.com>
13342 Javier Miranda <miranda@adacore.com>
13344 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13345 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13346 required exception handler.
13347 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13348 properly the case of a function whose return type is a limited
13349 class-wide interface type. Modify the code of the accessibility
13350 check to handle class-wide interface objects. In this case we need to
13351 displace "this" to reference the primary dispatch table to get access
13352 to the TSD of the object (to evaluate its accessibility level).
13353 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13354 rather than a controlling result as one of the conditions for
13355 generating tests of the implicit BIP_Alloc_Form formal. The
13356 initialization assignment is also handled according to whether the
13357 result is tagged instead of controlling.
13358 In the case where the init assignment is inserted in the "then" part of
13359 the allocation conditional, rewrite the target to be a dereference of
13360 the implicit BIP_Object_Access formal.
13361 If the returned value is unconstrained and created on the secondary
13362 stack, mark the enclosing block and function so that the secondary
13363 stack is not reclaimed on return.
13364 Treat returns from functions with controlling results similarly to
13365 returns from functions with unconstrained result subtypes.
13366 If the object returned is unconstrained, and an allocator must be
13367 created for it, analyze the allocator once the block for the extended
13368 return is installed, to ensure that finalizable components
13369 of the expression use the proper finalization list. Guard the call to
13370 Move_Final_List with a check that there is something to finalize.
13371 (Make_Tag_Ctrl_Assignment): Use "old" handling
13372 of controlled type assignment for virtual machines, since new code uses
13373 unsupported features (such as direct access to bytes in memory).
13375 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13376 Ed Schonberg <schonberg@adacore.com>
13378 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13379 accessibility actual, check for the case of an aliased object that has
13380 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13381 we fall into processing for the attribute rather than the name of the
13383 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13384 formal has its address taken in the body, create a temporary to capture
13385 value. If the return type is a limited interface, do not treat the
13386 return value as Controlled.
13387 (Is_In_Place_Function): If the return type is a limited interface,
13388 treat as returning in place. The actual returned object may not always
13389 be limited, but the caller has to assume that it is returned in place.
13390 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13391 context of an allocator, use the correct finalization chain (that is,
13392 the chain belonging to the access type, rather than the chain belonging
13393 to the current scope).
13394 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13395 result type rather than a controlling result as a precondition for
13396 adding an allocation form actual to a build-in-place call.
13397 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13398 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13399 primitive in the dispatch tables. This work is now done by Make_DT when
13400 the type is frozen.
13401 (Register_Predefined_DT_Entry): Removed.
13402 (Add_Return): If end label is not present, use sloc of last statement
13403 for generated return statement in procedure, for better gdb behavior
13405 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13406 object address nodes to ensure proper processing by routines like
13408 (Expand_Call): Fix generation of validity check for parameter
13409 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13410 the allocation form parameter if the result subtype is constrained,
13411 except when the function has a controlling result.
13412 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13413 rather than Is_Controlled and Has_Controlled_Component, since we want to
13414 include class-wide result types in this treatment. Also test for a
13415 controlling result, since that also requires passing a finalization
13417 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13418 even when the result subtype is constrained, to handle calls involving
13419 controlling results.
13420 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13421 is now called even when the result subtype is constrained, to handle
13422 calls involving controlling results.
13423 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13424 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13425 now performs the test).
13426 (Make_Build_In_Place_Call_In_Object_Declaration):
13427 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13428 constrained, to handle calls involving controlling results.
13429 (Add_Return): Accomodate rewritten pattern from local raise to goto

13450 subprogram instead of a plain "raise Program_Error" node to raise
13451 Program_Error if an exception is propagated from an Adjust or Finalize
13453 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13454 appears in the optional statement list of a triggering alternative, the
13455 scope actions can be inserted directly there, and not in the list that
13456 includes the asynchronous select itself.

13487 functionality when the backend is generating code.
13488 Otherwise any serious error
13489 reported by the backend calling the frontend routine Error_Msg
13490 changes the Compilation_Mode to Check_Semantics, disables the

13531 deallocation of class-wide interface objects.
13532 (Expand_Dispatching_Constructor_Call): Take into account that if the
13533 result of the dispatching constructor is an interface type, the
13534 function returns a class-wide interface type; otherwise the returned
13535 object would be actual. The frontend previously accepted returning
13536 interface types because Expand_Interface_Actuals silently performed
13537 the management of the returned type "as if" it were a class-wide
13539 (Expand_Dispatching_Constructor_Call): Replace call to
13540 Make_DT_Access_Action by direct call to Make_Function_Call.

13632 subtype from the function call, as is done for private types.
13633 (Side_Effect_Free): An expression that is the renaming of an object or
13634 whose prefix is the renaming of a object, is not side-effect free
13635 because it may be assigned through the renaming and its value must be
13636 captured in a temporary.

13749 defined in GNAT.IO, which might not be stdout
13750 (Is_Valid): Adjust comment to mention that a positive reply means that
13751 Header_Of may be used to retrieve the allocation header associated with

13776 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13779 2007-06-06 Vincent Celier <celier@adacore.com>
13782 Add 3 spaces before the default project directory when displaying
13783 the project search path.

14365 aggregate of a discriminated type, check that associations for any
14366 access discriminants satisfy accessibility requirements by calling

14389 both entities. This is required to statically build the dispatch table.
14390 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14391 of calling Set_All_DT_Position to re-evaluate the position of the
14392 entries in the dispatch table. Such reevaluation is not desired if

15261 (Resolve_Call): If the call returns an array, the context imposes the
15262 component type of the array, and the function has one non-defaulted
15263 parameter, rewrite the call as the indexing of a call with a single
15264 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15266 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15267 the master of the created object is the innermost enclosing statement.
15268 (Remove_Conversions): For a binary operator, check if type of second
15269 formal is numeric, to check if an abstract interpretation is present

15368 overriding" is subtly different from "is abstract" (see AI-228).
15369 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15370 Is_Abstract_Type. Make sure these are called only when appropriate.

15511 attempt to derive from a synchronized tagged type.

15516 that use (a subtype of) the class-wide type of the enclosing type.
15517 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15518 Derived_Type for Prev formal on call to
15519 Check_Anonymous_Access_Components rather than Empty.
15520 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15521 a record extension in deciding whether to create a class-wide type,

15602 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15603 when -gnatg is not specified.

15655 parameter of the containing subprogram.
15656 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15657 under No_Dispatching_Calls restriction. During the semantic analysis

15681 of the table of ancestors.
15682 (Expand_Interface_Conversion): Insert function body at the closest place
15683 to the conversion expression, to prevent access-before-elaboration
15684 errors in the backend.

15710 (Expand_Dispatching_Call): Replace generation of call to the run-time
15711 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15712 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15714 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15715 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15725 returns an actual parameter expression for both named and positional
15728 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15729 check violation of restriction No_Dispatching_Calls.
15730 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15737 specify Any_Limited_Interface, and this functionality is already
15738 provided by the function Has_Abstract_Interfaces.
15739 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15740 support concurrent types implementing interfaces.
15741 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15742 specify kind Any_Limited_Interface, and this functionality is already

15759 Cyrille Comar <comar@adacore.com>
15761 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15762 anonymous, use finalization list of enclosing dynamic scope.
15763 (Expand_N_Package_Declaration): For a library package declaration
15764 without a corresponding body, generate RACW subprogram bodies in the
15765 spec (just as we do for the task activation call).
15766 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15767 Is_Abstract_Type. Make sure these are called only when appropriate.
15768 Remove all code for DSP option
15769 (CW_Or_Controlled_Type): new subprogram.

15773 Gary Dismukes <dismukes@adacore.com>
15775 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15776 parameter. If it is set to true, return a result capped according to
15777 the global upper bound for the index of an entry family.
15778 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15779 (Build_Find_Body_Index): Adjust for above change.
15780 (Entry_Index_Expression): Likewise.
15781 (Is_Potentially_Large_Family): New function extracted from...

15783 is potentially large.
15784 (Build_Entry_Count_Expression): If the family is potentially large, call
15785 Family_Size with 'Cap' set to true.
15786 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15787 a protected version of an operation declared in the private part of
15788 a protected object, because they may be invoked through a callback.
15789 (Set_Privals): If the type of a private component is an anonymous access
15790 type, do not create a new itype for each protected body.
15791 If the body of a protected operation creates
15792 controlled types (including allocators for class-widetypes), the
15793 body of the corresponding protected subprogram must include a
15795 (Build_Activation_Chain_Entity): Build the chain entity for extended
15797 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15798 to determine whether operation overrides an inherited primitive.
15799 (Build_Wrapper_Spec): Add code to examine the parents while looking
15800 for a possible overriding candidate.
15801 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15802 hold an actual parameter value since its initialization is separated

15806 2007-04-06 Thomas Quinot <quinot@adacore.com>
15807 Pablo Oliveira <oliveira@adacore.com>
15809 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15810 Do an Unchecked_Conversion to handle the passage from the Underlying
15811 Type to the Base Type when calling Build_To_Any_Call and
15812 Build_From_Any_Call.
15813 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15814 E_Constant, depending upon Variable formal.
15815 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15816 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15817 parameter that requires an extra constrained parameter, declare
15818 temporary for actual as a variable, not a constant.
15819 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15820 the unit being compiled is the one that contains the stub type.
15821 Change primitive operation name for the RACW associated with a RAS
15822 from Call to _Call so it cannot clash with any legal identifier.
15823 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15825 (Append_RACW_Bodies): New subprogram.
15826 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15827 Add_Receiving_Stubs_To_Declarations functions.
15828 When expanding a package body, this list correspond to the
15829 statements in the HSS at the end of the pacakge.
15830 When expanding a package spec, this list correspond to the
15832 (Add_Receiving_Stubs_To_Declarations): Append the function
15833 registering the receiving stubs at the end of the 'Stmts' list.
15834 (RCI_Package_Locator): Pass the new Version generic formal when
15835 instantiating a RCI_Locator package.
15836 (Build_From_Any_Function): To compute the High bound for an
15837 unconstrained array actual, we add the Low bound with the length.
15838 Thus we must convert the low bound and the length to an appropriate
15839 type before doing the sum.
15840 (Build_Subprogram_Receiving_Stubs, PolyORB):
15841 * Retrieve the extra formals parameters at the
15842 end of the parameter stream.
15843 * Use Move_Any_Value to write back out parameters
15844 after executing the request as it is more efficient
15845 than Copy_Any_Value.
15846 * Build the any containing Extra Formals with the
15847 appropriate typecode.
15848 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15849 empty Component_List.
15850 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15851 the tree the declaration for an object that serves as actual parameter
15852 in server-side stubs.
15853 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15854 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15855 Use Build_Actual_Object_Declaration to prepare the actuals.

15857 Extra Constrained Parameters.
15858 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15859 Extra Constrained parameters.
15860 (Build_To_Any_Function, Build_From_Any_Function,

15862 function with the first not implicit parent type.
15863 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15864 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15865 typecode from the Etype. Therefore we retrieve the correct typecode
15866 with a call to Get_Any_Type.
15867 (Copy_Specification): Do controlling formal type substitution based on
15868 Is_Controlling_Formal flag, instead of caller-provided object type.
15869 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15870 a RACW primitive operation, we might get a subprogram declaration for an
15871 ancestor of the RACW designated type (not for the designated type
15872 itself), in the case where this operation is inherited. In this case we
15873 have no easy means of determining the original tagged type for which
15874 the primitive was declared, so instead we now rely on
15875 Copy_Specification to use the Is_Controlling_Formal flag to determine
15876 which formals require type substitution.

15882 GNAT.Current_Exception are not allowed if pragma Restrictions
15883 (No_Exception_Propagation) is set and in any case make the associated
15884 handler unsuitable as a target for a local raise statement.
15885 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15886 run-time subprogram CW_Membership by call to Build_CW_Membership.
15887 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15888 by a function call, a temporary must be created before expanding the
15889 Constructor_Call itself, to prevent out-of-order elaboration in the
15890 back-end when stack checking is enabled..
15892 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15894 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15895 result are the bounds of the left operand, not the right.
15897 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15900 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15912 box corresponds to a component of the type.
15913 (Resolve_Record_Aggregate): Split Is_Abstract flag into

16019 standard 8bits encoding.
16020 (WS2SU): As above but converting from wide-sring to string.
16021 This is needed as it is necessary to have access to both versions in the
16022 runtime for the form parameter encoding support.
16023 This set of patch add support for the encoding form parameter.
16024 (S2WS): Improve implementation to handle cases where the filename is not
16025 UTF-8 encoded. In this case we default to using the current code page
16026 for the conversion.

16073 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16074 __gnat_adjust_context_for_raise.
16075 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16076 implementation of floating point operations as native x86 targets.
16077 So the FPU should be initialized in the same way using finit. Fix
16078 floating point operations accuracy issues.

16101 building the entry for the type.
16102 (Generate_Definition): Initialize component Def and Typ of new entry
16103 in table Xrefs, to avoid to have these components unitialized.

16149 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16150 it no longer destroys the contents of Name_Buffer or Name_Len and
16151 non-standard and invalid names are handled better.
16152 (Get_Decoded_Name_String): Improve performance by using
16153 Name_Has_No_Encodings flag in the name table.
16154 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16155 Used for debugging printouts.

16161 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16162 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16163 there is no need to generate always a record_definition_node in case
16164 of synchronized interface types.
16165 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16166 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16167 illegal in Ada 95, in cases where it is legal. Change the warnings to
16168 errors in other cases. Don't give the error unless the "not null"
16169 parses properly. Correct the source position at which the error occurs.
16170 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16171 P_Null_Exclusion, to suppress "not null" warnings.

16223 Entry for pragma Unreferenced_Objects
16225 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD

16247 the default project path, initially done during elaboration of the
16249 If the prefix returned by Sdefault is null, get the prefix from a call
16250 to Executable_Prefix_Path.
16251 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16254 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16255 canonical directory name to open the directory from which files are
16257 (Record_Other_Sources): Idem.
16258 (Locate_Directory): Add the possibility to create automatically missing
16259 directories when Setup_Projects is True.

16262 library source copy dir and exec dir.
16264 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16267 2007-04-06 Robert Dewar <dewar@adacore.com>

16302 full word is no longer compared twice.
16304 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16306 * sem_ch10.adb (Install_Limited_Context_Clauses.
16307 Expand_Limited_With_Clause): Use a new copy of selector name in the
16308 call to Make_With_Clause. This fixes the tree structure for ASIS
16309 purposes. Nothing is changed in the compiler behaviour.
16310 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16311 a package renaming.
16312 (Install_Limited_With_Clauses): Do not install non-limited view when it
16313 is still incomplete.
16315 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16316 Gary Dismukes <dismukes@adacore.com>
16318 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16319 when capturing size information, instead of base type, which for a
16320 formal array type will be the unconstrained type.
16321 (Analyze_Formal_Object_Declaration): Add check for illegal default
16322 expressions for a formal in object of a limited type.
16323 (Instantiate_Object): Ditto.
16324 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16325 because they were defaulted in the formal package and no check applies
16327 (Check_Formal_Package_Instance): Extend conformance check to other
16328 discrete types beyond Integer.
16329 (Process_Default): Copy directly the unmatched formal. A generic copy
16330 has already been performed in Analyze_Formal_Package.
16331 (Analyze_Associations): If a formal subprogram has no match, check for
16332 partial parametrization before looking for a default, to prevent
16334 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16335 not set the instantiation environment before analyzing the actuals.
16336 Fixes regression on 8515-003 with implementation of AI-133.
16337 Set_Instance_Env checks whether the generic unit is a predefined
16338 unit, in which case the instance must be analyzed with the latest Ada
16339 mode. This setting must take place after analysis of the actuals,
16340 because the actuals must be analyzed and frozen in the Ada mode extant
16341 outside of the current instantiation.
16342 (Save_Env, Restore_Env): Preserve and restore the configuration
16343 parameters so that predefined units can be compiled in the proper Ada
16345 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16346 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16347 and Is_Abstract_Type.
16348 (Analyze_Formal_Package): For better error recovery, Add exception
16349 handler to catch Instantion_Error, which can be raised in
16350 Analyze_Associations
16352 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16353 Bob Duff <duff@adacore.com>
16354 Gary Dismukes <dismukes@adacore.com>
16356 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16357 prefix type is a discriminated subtype of the type of the formal.
16358 (Analyze_Allocator): Collect all coextensions regardless of the context.
16359 Whether they can be allocated statically is determined in exp_ch4.
16360 (Analyze_Selected_Component): If the prefix is a limited view and the
16361 non-limited view is available, use the non-limited one.
16362 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16363 therefore illegal), suggest a qualified expression rather than a type
16364 conversion, because a type conversion would be illegal in this context.
16365 (Anayze_Allocator): Trace recursively all nested allocators so that all
16366 coextensions are on the corresponding list for the root. Do no mark
16367 coextensions if the root allocator is within a declaration for a stack-
16368 allocated object, because the access discriminants will be allocated on
16370 (Analyze_Call): Remove restriction on calls to limited functions for the
16371 cases of generic actuals for formal objects, defaults for formal objects
16372 and defaults for record components.
16373 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16374 element list. Their expansion is delayed until the enclosing allocator
16375 is processed and its finalization list constructed.
16376 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16377 for an operation with the given name among the primitive operations of
16378 the corresponding record type.
16379 (Analyze_Selected_Component): If the prefix is a task type that
16380 implements an interface, and there is no entry with the given name,
16381 check whether there is another primitive operation (e.g. a function)
16383 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16384 properly the indexing of a function call written in prefix form, where
16385 the function returns an array type, and all parameters of the function
16386 except the first have defaults.
16387 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16388 the original operands, rather than relocating them, for efficiency and
16389 to work properly when an operand is overloaded.
16390 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16391 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16392 (Analyze_Selected_Component): If the prefix is a private extension, only
16393 scan the visible components, not those of the full view.
16394 (Try_Primitive_Operation): If the operation is a procedure, collect all
16395 possible interpretations, as for a function, because in the presence of
16396 classwide parameters several primitive operations of the type can match
16397 the given arguments.
16399 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16400 Robert Dewar <dewar@adacore.com>
16402 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16403 tag-indeterminate call to an abstract function, when the left-hand side
16405 (Analyze_Loop_Statement): Improve detection of infinite loops
16407 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16408 Thomas Quinot <quinot@adacore.com>
16410 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16411 out of Analyze_Package_Declaration, because processing must be applied
16412 to package bodies as well, for deferred constants completed by pragmas.
16413 (Analyze_Package_Declaration): When the package declaration being
16414 analyzed does not require an explicit body, call Check_Completion.
16415 (May_Need_Implicit_Body): An implicit body is required when a package
16416 spec contains the declaration of a remote access-to-classwide type.
16417 (Analyze_Package_Body): If the package contains RACWs, append the
16418 pending subprogram bodies generated by exp_dist at the end of the body.
16419 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16420 Is_Abstract_Subprogram and Is_Abstract_Type.
16421 (Preserve_Full_Attributes): The full entity list is not an attribute
16422 that must be preserved from full to partial view.
16424 * sem_dist.adb (Add_RAS_Dereference_TSS):
16425 Change primitive name to _Call so it cannot clash with any legal
16426 identifier, and be special-cased in Check_Completion.
16427 Mark the full view of the designated type for the RACW associated with
16428 a RAS as Comes_From_Source to get proper view switching when installing
16429 private declarations.
16430 Provite a placeholder nested package body along with the nested spec
16431 to have a place for Append_RACW_Bodies to generate the calling stubs
16432 and stream attributes.
16434 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16435 Robert Dewar <dewar@adacore.com>
16437 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16438 that is a limited view, check the non-limited view if available.
16439 (Undefined): Refine error message for missing with of Text_IO
16440 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16441 to distinguish real missing with cases.
16442 Fix format of all missing with messages
16443 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16444 renaming as body when renamed entity is abstract.
16446 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16447 Javier Miranda <miranda@adacore.com>
16449 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16450 predicate recursive, to handle complex expressions on literals whose
16451 spurious ambiguity comes from the abstract interpretation of some
16453 (Interface_Present_In_Ancestor): Add support to concurrent record
16455 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16456 Is_Abstract_Subprogram and Is_Abstract_Type.
16458 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16459 Javier Miranda <miranda@adacore.com>
16461 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16462 dereference of a local object R created as a reference to another
16463 object O, use the access level of O.
16464 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16465 rather than local Same_Formal_Type, to check whether protected operation
16466 overrides an inherited one.
16467 (Same_Formal_Type): New predicate, used when matching signatures of
16468 overriding synchronized operations, to handle the case when a formal
16469 has a type that is a generic actual.
16470 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16471 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16472 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16473 syntactic ambiguities involving indexing of function calls that return
16475 (Abstract_Interface_List): New subprogram that returns the list of
16476 abstract interfaces associated with a concurrent type or a
16477 concurrent record type.
16478 (Interface_Present_In_Parent): New subprogram used to check if a
16479 given type or some of its parents implement a given interface.
16480 (Collect_Abstract_Interfaces): Add support for concurrent types
16481 with interface types.
16482 (Has_Abstract_Interfaces): Add support for concurrent types with
16484 (Is_Parent): New subprogram that determines whether E1 is a parent
16485 of E2. For a concurrent type its parent is the first element of its
16486 list of interface types; for other types this function provides the
16487 same result than Is_Ancestor.
16488 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16489 (Collect_Synchronized_Interfaces): Removed because the subprogram
16490 Collect_Abstract_Interfaces provides this functionality.
16491 (Collect_Abstract_Interfaces): Minor update to give support to
16492 concurrent types and thus avoid undesired code duplication.
16493 (Get_Subprogram_Entity): Handle entry calls.
16494 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16496 (Enter_Name): Do not give -gnatwh hiding warning for record component
16497 entities, they never result in hiding.

16506 New field Exception_Label added
16507 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16508 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

16512 can be an E_Return_Statement.
16513 (Is_Coextension): New flag for allocators.

16521 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16522 before propagating exception.
16524 2007-04-06 Olivier Hainque <hainque@adacore.com>
16526 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16527 an address always within the call instruction from a return address.
16529 2007-04-06 Olivier Hainque <hainque@adacore.com>
16530 Eric Botcazou <botcazou@adacore.com>
16532 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16533 expression with a COMPOUND_EXPR including the call instead of emitting
16534 the call directly here.
16535 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16536 high bound is constant and the slice is empty. Tidy.
16537 (tree_transform, case N_Op_Not): Handle properly the case where the
16538 operation applies to a private type whose full view is a modular type.
16539 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16540 Address_Clause, use the associated Expression as the GNAT tree
16541 representing the choice value to ensure the corresponding GCC tree is
16542 of the proper kind.
16543 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16544 instead of just the operands, as the base GCC stabilize_reference does.
16545 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16546 requested; otherwise fail.
16547 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16549 2007-04-06 Thomas Quinot <quinot@adacore.com>

16552 implementation of UI_Div.
16553 (UI_Div): Reimplement as a call to UI_Div_Rem.
16554 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16555 remainder, avoiding the cost of a multiplication and a subtraction.
16556 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16557 provides both quotient and remainder in a single computation.
16558 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16559 functions for uint.
16560 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16561 is undefined if the given n is not inversible.
16563 2007-04-06 Olivier Hainque <hainque@adacore.com>
16565 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
16566 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion
16569 2007-04-06 Eric Botcazou <botcazou@adacore.com>
16570 Olivier Hainque <hainque@adacore.com>
16572 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16573 when updating the contents of the old pointer to an unconstrained array.
16574 (end_subprog_body): Set error_gnat_node to Empty.
16575 (write_record_type_debug_info): Do not be unduly sparing with our bytes.
16576 (unchecked_convert): For subtype to base type conversions, require that
16577 the source be a subtype if it is an integer type.

16826 Valid_Conversion, to incorporate accessibility checks for arrays of
16827 anonymous access types.
16828 (Valid_Conversion): For a conversion to a numeric type occurring in an
16829 instance or inlined body, no need to check that the operand type is
16830 numeric, since this has been checked during analysis of the template.

16886 zone data and calculate the GMT offset.

17535 the parent part is a build-in-place function call, generate assignments.
17536 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17537 are build-in-place function calls.
17538 (Replace_Self_Reference): New subsidiary of
17539 Make_OK_Assignment_Statement, to replace an access attribute that is a
17540 self-reference into an access to the appropriate component of the
17541 target object. Generalizes previous mechanism to handle self-references
17542 nested at any level.
17543 (Is_Self_Referential_Init): Remove, not needed.
17544 (Is_Self_Referential_Init): New predicate to simplify handling of self
17545 referential components in record aggregates.
17546 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17547 check for presence of entity before checking for self-reference.
17548 (Has_Default_Init_Comps): Return True if a component association is a
17549 self-reference to the enclosing type, which can only come from a
17550 default initialization.
17551 (Make_OK_Assignment_Statement): If the expression is of the form
17552 Typ'Acc, where Acc is an access attribute, the expression comes from a
17553 default initialized self-referential component.
17554 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17555 that has been derived from several abstract interfaces we must also
17556 initialize the tags of the secondary dispatch tables.

17560 Javier Miranda <miranda@adacore.com>
17561 Robert Dewar <dewar@adacore.com>
17564 (Expand_Access_To_Protected_Op): If the context indicates that an access
17565 to a local operation may be transfered outside of the object, create an
17566 access to the wrapper operation that must be used in an external call.
17567 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17568 target, pass the Valid attribute applied to a floating-point prefix on
17569 to the back end without expansion.
17570 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17571 the allocated storage when it is specified by a per-object expression.
17572 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17573 Nothing to do here, the attribute has been rewritten during semantic

17577 (Find_Fat_Info): Handle case of universal real
17578 (Expand_Access_To_Protected_Op): Fix use of access to protected
17579 subprogram from inside the body of a protected entry.
17580 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17581 'Access and 'Unrestricted_Access, to transform the attribute reference
17582 into a fat pointer.
17583 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17584 subcomponent's enclosing variable is aliased with a constrained subtype.
17585 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17586 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17587 an aliased prefix must be known to be constrained in order to use True
17588 for the attribute value, and now it's possible for some aliased views
17589 to be unconstrained.
17591 2006-10-31 Robert Dewar <dewar@adacore.com>
17593 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17594 (Expand_Entity_Reference): Correct error of not handling subprogram
17595 formals in current_value processing.

17600 Gary Dismukes <dismukes@adacore.com>
17602 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17603 register in the final list objects containing class-wide interfaces;
17604 otherwise we incorrectly register the tag of the interface in the final
17606 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17607 generate the wrapper if the parent primitive is abstract. This is
17608 required to report the correct error message.
17609 (Expand_N_Subtype_Indication): Do validity checks on range
17610 (Clean_Task_Names): If an initialization procedure includes a call to
17611 initialize a task (sub)component, indicate that the procedure will use
17612 the secondary stack.
17613 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17614 compatibility for interfacing with CPP by default.
17615 (Expand_N_Object_Declaration): Only build an Adjust call when the
17616 object's type is a nonlimited controlled type.
17617 * exp_ch3.adb: Add with and use of Exp_Ch6.
17618 (Expand_N_Object_Declaration): Check for object initialization that is a
17619 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17620 Object_Declaration to the call.
17621 (Freeze_Type): When the designated type of an RACW was not frozen at the
17622 point where the RACW was declared, validate the primitive operations
17623 with respect to E.2.2(14) when it finally is frozen.
17624 (Build_Initialization_Call,Expand_Record_Controller): Rename
17625 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17626 return-by-reference has no meaning in Ada 2005.
17627 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17628 to register tag of the immediate ancestor interfaces in the
17629 run-time structure.
17630 (Init_Secondary_Tags): Moved to the specification to allow the
17631 initialization of extension aggregates with abstract interfaces.
17632 (Build_Master_Renaming): Make public, for use by function declarations
17633 whose return type is an anonymous access type.
17634 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17635 Insert_List_Before_And_Analyze after the generation of the specs
17636 associated with null procedures.
17637 (Expand_Tagged_Root): Update documentation in its specification.
17638 (Init_Secondary_Tags): Update documentation.
17639 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17640 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17641 then generate code to inherit the contents of the dispatch table
17642 directly from the ancestor.
17643 (Expand_Record_Controller): Insert controller component after tags of
17644 implemented interfaces.
17645 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17646 create null procedure overridings when null procedures are inherited
17648 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17649 declarations for overriding null primitives inherited from interfaces.
17650 (Is_Null_Interface_Procedure): New function in
17651 Make_Null_Procedure_Specs.
17652 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17653 immediate ancestor of a tagged type is an abstract interface type we
17654 must generate the specification of the predefined primitives associated
17655 with controlled types (because the dispatch table of the ancestor is
17656 null and hence these entries cannot be inherited). This is required to
17657 elaborate well the dispatch table.

17667 (Expand_N_In): Do validity checks on range
17668 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17669 (Expand_N_Allocator): For "new T", if the object is constrained by
17670 discriminant defaults, allocate the right amount of memory, rather than
17671 the maximum for type T.
17672 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17673 when the allocator is initialized by a build-in-place call, since the
17674 allocator is already rewritten as a reference to the function result,
17675 and this prevents an unwanted duplication of the function call.
17676 Add with and use of Exp_Ch6.
17677 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17678 is a call to build-in-place function and apply
17679 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17680 untagged designated types).
17681 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17682 optimization if source or target is biased.
17683 (Expand_N_Allocator): Add comments for case of an allocator within a
17684 function that returns an anonymous access type designating tasks.
17685 (Expand_N_Allocator): apply discriminant checks for access
17686 discriminants of anonymous access types (AI-402, AI-416)

17695 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17696 (Expand_N_Assignment_Statement): Call
17697 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17698 build-in-place function call. Currently, this can happen only for
17699 assignments that come from aggregates.
17700 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17701 in order to alleviate the upward compatibility introduced by AI-318.
17702 (Expand_N_Extended_Return_Statement): Add support for handling the
17703 return object as a build-in-place result.
17704 (Expand_Non_Function_Return): Implement simple return statements nested
17705 within an extended return.
17706 (Enable_New_Return_Processing): Turn on the new processing of return
17708 (Expand_Non_Function_Return): For a return within an extended return,
17709 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17710 (Expand_N_Extended_Return_Statement): Implement AI-318
17711 (Expand_Simple_Function_Return): Ditto.
17712 (Expand_N_If_Statement): Handle new -gnatwt warning

17714 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17715 a protected object.
17716 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17717 validity checking of assignments to elementary record components.
17718 (Expand_N_Return_Statement): return Class Wide types on the secondary
17719 stack independantly of their controlled status since with HIE runtimes,
17720 class wide types are not potentially controlled anymore.
17722 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17725 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17726 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17727 it expects a block, procedure, or task. The return statement will get
17728 turned into a block, and Expand_Cleanup_Actions will happen then.

17732 Bob Duff <duff@adacore.com>
17733 Gary Dismukes <dismukes@adacore.com>
17735 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17737 (Expand_Inlined_Call): Tagged types are by-reference types, and
17738 therefore should be replaced by a renaming declaration in the expanded
17739 body, as is done for limited types.
17740 (Expand_Call): If this is a call to a function with dispatching access
17741 result, propagate tag from context.
17742 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17744 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17745 build-in-place when the right-hand side of an assignment is a
17746 build-in-place function call.
17747 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17748 of the explicit dereference of the allocator to the result subtype of
17749 the build-in-place function. This is needed to satisfy type checking
17750 in cases where the caller's return object is created by an allocator for
17751 a class-wide access type and the type named in the allocator is a
17753 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17754 conversion of the reference to the declared object to the result subtype
17755 of the build-in-place function. This is needed to satisfy type checking
17756 in cases where the declared object has a class-wide type. Also, in the
17757 class-wide case, change the type of the object entity to the specific
17758 result subtype of the function, to avoid passing a class-wide object
17759 without explicit initialization to the back end.
17760 (Register_Interface_DT_Entry): Moved outside the body of
17761 Freeze_Subprogram because this routine is now public; it is called from
17762 Check_Dispatching_Overriding to handle late overriding of abstract
17763 interface primitives.
17764 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17765 adding an implicit access actual on a call to a build-in-place function.
17766 (Expand_Actuals): Test for an actual parameter that is a call to a
17767 build-in-place function and apply
17768 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17769 (Is_Build_In_Place_Function): New function to determine whether an
17770 entity is a function whose calls should be handled as build-in-place.
17771 (Is_Build_In_Place_Function_Call): New function to determine whether an
17772 expression is a function call that should handled as build-in-place.
17773 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17774 calls to build-in-place functions as the initialization of an allocator.
17775 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17776 handling calls to build-in-place functions in contexts that do not
17777 involve init of a separate object (for example, actuals of subprogram
17779 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17780 handling calls to build-in-place functions as the initialization of an
17781 object declaration.
17782 (Detect_Infinite_Recursion): Add explicit parameter Process to
17783 instantiation of Traverse_Body to avoid unreferenced warning.
17784 (Check_Overriding_Inherited_Interfaces): Removed.
17785 (Register_Interface_DT_Entry): Code cleanup.
17786 (Register_Predefined_DT_Entry): Code cleanup.
17787 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17788 inlined statements if within a transient scope.
17789 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17790 formal parameters with occurrences of actuals in inlined body, establish
17791 visibility on the proper view of the actual's subtype for the body's
17793 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17794 compatibility mode and we have an imported CPP subprogram because
17795 for now we assume that imported CPP primitives correspond with
17796 objects whose constructor is in the CPP side (and therefore we
17797 don't need to generate code to register them in the dispatch table).
17798 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17799 aligned selected component.
17800 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17801 the actual of an in-mode parameter is a type conversion.
17802 (Expand_Actuals): If the call does not come from source and the actual
17803 is potentially misaligned, let gigi handle it rather than rejecting the
17804 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17805 Class Wide types as returning by reference independantly of their
17806 controlled status since with HIE runtimes class wide types are not
17807 potentially controlled anymore.
17809 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17811 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17812 references that are private components of the protected object.

17814 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17815 instantiation to deal with warnings.

17822 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17823 initialization of Homonym_Len.
17824 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17825 names from fully qualified name. Fixes problem of duplicate
17826 external names differing only in the presence of such a block name.
17828 2006-10-31 Thomas Quinot <quinot@adacore.com>
17829 Pablo Oliveira <oliveira@adacore.com>
17831 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17832 subprogram Ids, even if they are not yet assigned.
17833 (Build_Subprogram_Id): It is now this function that will take care of
17834 calling Assign_Subprogram_Ids if necessary.
17835 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17836 should be done only once they are assigned.
17837 (Build_From_Any_Function, case of tagged types): Add missing call to
17839 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17840 type for an RACW type.
17841 (Add_RACW_Features): When processing an RACW declaration for which the
17842 designated type is already frozen, enforce E.2.2(14) rules immediately.
17843 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17844 special reordering of controlling formals.
17846 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17847 associated stub type for an RACW type.
17849 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17851 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17852 fixed-point operations in an integer context, i.e. as operands of a
17853 conversion to an integer type, indicate that result must be rounded.
17855 2006-10-31 Robert Dewar <dewar@adacore.com>
17857 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17858 cases, pass the encoding method, since it is now required by the run
17861 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17862 assumption that Str'First = 1.
17863 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17864 it on to the Value_Wide_Wide_Character call.
17865 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17866 properly handles a string of the form quote-encoded_wide_char-quote.
17868 * s-wchcnv.adb: Minor reformatting
17870 2006-10-31 Javier Miranda <miranda@adacore.com>
17872 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17873 run-time membership test to ensure that the constructed object
17874 implements the target abstract interface.
17876 2006-10-31 Robert Dewar <dewar@adacore.com>
17878 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17879 Machine_Attribute pragma internally to implement the user pragma.
17880 Add processing for pragma Interface so that it is now completely
17881 equivalent to pragma Import.
17883 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17884 so that it can be applied to all entities, including record components
17885 and enumeration literals.
17886 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17887 priority ranges are correct, verify compatibility against task
17888 dispatching and locking policies, and if everything is correct an entry
17889 is added to the table containing priority specific dispatching entries
17890 for this compilation unit.
17891 (Delay_Config_Pragma_Analyze): Delay processing
17892 Priority_Specific_Dispatching pragmas because when processing the
17893 pragma we need to access run-time data, such as the range of
17894 System.Any_Priority.
17895 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17896 Allow pragma Unreferenced as a context item
17897 Add pragma Preelaborable_Initialization

17899 now syntactically and semantically equivalent to Import.
17900 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17901 insertion characters.
17902 Add handling for Pragma_Wide_Character_Encoding
17903 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17904 never supercedes a real restriction, and that a real restriction
17905 always supercedes a warning.
17906 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17911 Robert Dewar <dewar@adacore.com>
17913 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17914 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17915 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17917 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17918 type of the function containing a return statement, because the
17919 Return_Type field was removed. We now use the Return_Applies_To field.
17921 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17922 (Build_Task_Image_Decl): If procedure is not called from an
17923 initialization procedure, indicate that function that builds task name
17924 uses the sec. stack. Otherwise the enclosing initialization procedure
17925 will carry the indication.
17926 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17927 N_Object_Declaration instead.
17928 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17929 conditional dead code killed, and change implementation accordingly.
17930 (Insert_Actions): Add N_Return_Object_Declaration case.
17931 Correct comment to mention N_Extension_Aggregate node.
17932 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17933 attempts to save information for global variables which cannot be
17935 (Get_Current_Value_Condition): Handle conditions the other way round
17936 (constant on left). Also handle right operand of AND and AND THEN
17937 (Set_Current_Value_Condition): Corresponding changes
17938 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17939 (Get_Current_Value_Condition): Handle simple boolean operands
17940 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17941 (Get_Current_Value_Condition): If the variable reference is within an
17942 if-statement, does not appear in the list of then_statments, and does
17943 not come from source, treat it as being at unknown location.
17944 (Get_Current_Value_Condition): Enhance to allow while statements to be
17945 processed as well as if statements.
17946 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17948 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17949 of loop. This is safe now that we fixed Kill_Current_Values.
17950 (OK_To_Do_Constant_Replacement): Check whether current scope is
17951 Standard, before examining outer scopes.
17953 2006-10-31 Vincent Celier <celier@adacore.com>
17955 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17956 When True, apply VMS treatment to children of packages A, G, I and S.
17959 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17961 2006-10-31 Robert Dewar <dewar@adacore.com>

17965 (Warn_Overlay): Supply missing continuation marks in error msgs
17966 (Freeze_Entity): Add check for Preelaborable_Initialization
17968 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17970 * g-expect.adb: Add Warnings (Off) to prevent new warning
17972 * lib-xref.adb: Add handling of Last_Assignment field
17973 (Generate_Reference): Centralize handling of pragma Obsolescent here
17974 (Generate_Reference): Accept an implicit reference generated for a
17975 default in an instance.
17976 (Generate_Reference): Accept a reference for a node that is not in the
17977 main unit, if it is the generic body corresponding to an subprogram
17980 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17982 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17984 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17986 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17987 use clauses, to avoid messages on packages used to qualify, and also
17988 to avoid messages from obsolescent units.
17989 (Warn_On_Useless_Assignments): Don't generate messages for imported
17990 and exported variables.
17991 (Warn_On_Useless_Assignments): New procedure
17992 (Output_Obsolescent_Entity_Warnings): New procedure
17993 (Check_Code_Statement): New procedure
17995 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

17997 (Last_Assignment): New field for useless assignment warning
17999 2006-10-31 Olivier Hainque <hainque@adacore.com>
18001 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18002 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18004 2006-10-31 Bob Duff <duff@adacore.com>
18005 Robert Dewar <dewar@adacore.com>
18006 Ed Schonberg <schonberg@adacore.com>
18008 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18009 Ada 95 mode, because it violates the new rules for AI-318.
18011 * g-awk.ads: Use overloaded subprograms in every case where we used to
18012 have a default of Current_Session. This makes the code closer to be
18013 correct for both Ada 95 and 2005.
18015 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18016 code, relying on the fact that the compiler generates a warning
18017 instead of an error in -gnatg mode.
18019 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18020 E_Return_Statement entity kind.
18021 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18023 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18024 report an error if the reserved word abstract has been previously found.
18025 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18027 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18028 parenthesized range attribute usage
18029 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18031 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18032 in the syntax for extended_return_statement. This is not in the latest
18033 RM, but the ARG is expected to issue an AI allowing this.
18034 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18035 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18036 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18037 P_Return_Statement): Parse the new syntax for extended_return_statement.
18039 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18040 Output_End_Missing): Add error-recovery code for the new
18041 extended_return_statement syntax; that is, the new E_Return entry on
18044 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18045 limited to nonlimited, because otherwise we violate the new Ada 2005
18046 rules about returning limited types in function Create_AST_Handler in
18049 * sem.adb (Analyze): Add cases for new node kinds
18050 N_Extended_Return_Statement and N_Return_Object_Declaration.
18052 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18053 type is in the same category as type of context before applying check,
18054 to prevent anomalies in instantiations.
18055 (Resolve_Aggregate): Remove test for limited components in aggregates.
18056 It's unnecessary in Ada 95, because if it has limited components, then
18057 it must be limited. It's wrong in Ada 2005, because limited aggregates
18059 (Resolve_Record_Aggregate): Move check for limited types later, because
18060 OK_For_Limited_Init requires its argument to have been resolved.
18061 (Get_Value): When copying the component default expression for a
18062 defaulted association in an aggregate, use the sloc of the aggregate
18063 and not that of the original expression, to prevent spurious
18064 elaboration errors, when the expression includes function calls.
18065 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18066 were missing. We also didn't handle qualified expressions. Now also
18067 allow function calls. Use new common routine OK_For_Limited_Init.
18068 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18069 with space can upper case letter).
18071 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18072 Has_Static_Discriminants flag
18073 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18074 type with discriminants.
18075 (Process_Range_Expr_In_Decl): Do validity checks on range
18076 (Build_Discriminant_Constraints): Use updated form of
18077 Denotes_Discriminant.
18078 (Process_Subtype): If the subtype is a private subtype whose full view
18079 is a concurrent subtype, introduce an itype reference to prevent scope
18081 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18082 Record_Type_Declaration): The functionality of the subprograms
18083 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18084 is now performed by a single routine.
18085 (Build_Derived_Record_Type): If the type definition includes an explicit
18086 indication of limitedness, then the type must be marked as limited here
18087 to ensure that any access discriminants will not be treated as having
18088 a local anonymous access type.
18089 (Check_Abstract_Overriding): Issue a detailed error message when an
18090 abstract subprogram was not overridden due to incorrect mode of its
18092 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18093 synchronized private extension declarations. Verify that the ancestor is
18094 a limited or synchronized interface or in the generic case, the ancestor
18095 is a tagged limited type or synchronized interface and all progenitors
18096 are either limited or synchronized interfaces.
18097 Derived_Type_Declaration): Check for presence of private extension when
18098 dealing with synchronized formal derived types.
18099 Process_Full_View): Enchance the check done on the usage of "limited" by
18100 testing whether the private view is synchronized.
18101 Verify that a synchronized private view is completed by a protected or
18103 (OK_For_Limited_Init_In_05): New function.
18104 (Analyze_Object_Declaration): Move check for limited types later,
18105 because OK_For_Limited_Init requires its argument to have been resolved.
18106 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18107 in order to alleviate the upward compatibility introduced by AI-318.
18108 (Constrain_Corresponding_Record): If the constraint is for a component
18109 subtype, mark the itype as frozen, to avoid out-of-scope references to
18110 discriminants in the back-end.
18111 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18112 this subprogram against wrong sources.
18113 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18114 discriminant of limited type completed with a protected type, when the
18115 discriminant is used to constrain a private component of the type, and
18116 expansion is disabled.
18117 (Find_Type_Of_Object): Do not treat a return subtype that is an
18118 anonymous subtype as a local_anonymous_type, because its accessibility
18119 level is the return type of the enclosing function.
18120 (Check_Initialization): In -gnatg mode, turn the error "cannot
18121 initialize entities of limited type" into a warning.
18122 (OK_For_Limited_Init): Return true for generated nodes, since it
18123 sometimes violates the legality rules.
18124 (Make_Incomplete_Declaration): If the type for which an incomplete
18125 declaration is created happens to be the currently visible entity,
18126 preserve the homonym chain when removing it from visibility.
18127 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18128 inherited subprograms.
18129 (Access_Definition): If this is an access to function that is the return
18130 type of an access_to_function definition, context is a type declaration
18131 and the scope of the anonymous type is the current one.
18132 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18133 incomplete subtype to the set of private dependents of the original
18135 (Constrain_Discriminated_Type): Emit an error message whenever an
18136 incomplete subtype is being constrained.
18137 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18138 corresponding subtype of the full view of the original incomplete type.
18139 (Check_Incomplete): Properly detect invalid usage of incomplete types
18142 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18144 * g-catiio.ads, g-catiio.adb (Value): New function.

18153 Robert Dewar <dewar@adacore.com>
18155 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18156 handling executable extension manually and duplicating code.
18158 * make.adb: Implement new -S switch
18159 (Gnatmake): Use new function Osint.Executable_Name instead
18160 of handling executable extension manually.
18162 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18163 is specified, the executable name ends with this suffix.
18164 Take advantage of Osint.Executable_Name instead of duplicating code.
18166 * switch-m.adb: Recognize new gnatmake -S switch
18168 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18170 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18173 * makeusg.adb: Add line for gnatmake -S switch
18175 2006-10-31 Vincent Celier <celier@adacore.com>
18177 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18178 call it with -static-libgcc, as there are some platforms, such as
18179 Darwin, where one of these two switches is compulsory to link.
18181 2006-10-31 Vincent Celier <celier@adacore.com>
18183 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18184 instead of ADA_PROJECT_PATH, for the project path.
18185 (Gnatls): When displaying the project path directories, use host dir
18188 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18189 names in the project path, as absolute paths may correspond to
18190 multi-valued VMS logical names.
18192 2006-10-31 Vincent Celier <celier@adacore.com>
18194 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18195 absolute path name.
18196 (Locate_Regular_File): Ditto
18197 (Change_Dir): Remove, no longer used
18198 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18199 on Windows. Get it calling Get_Current_Dir.
18200 (OpenVMS): Remove imported boolean, no longer needed.
18201 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18202 (Pid_To_Integer): New function to convert a Process_Id to Integer
18204 2006-10-31 Thomas Quinot <quinot@adacore.com>
18206 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18207 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18209 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18212 2006-10-31 Robert Dewar <dewar@adacore.com>

18219 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18221 2006-10-31 Robert Dewar <dewar@adacore.com>
18223 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18225 (Layout_Variant_Record): Retrieve the discriminants from the entity
18226 rather than from the type definition, because in the case of a full
18227 type for a private type we need to take the discriminants from the
18229 (Layout_Component_List): When applying the Max operator to variants with
18230 a nonstatic size, check whether either operand is static and scale that
18231 operand from bits to storage units before applying Max.
18232 (Layout_Type): In VMS, if a C-convention access type has no explicit
18233 size clause (and does not inherit one in the case of a derived type),
18234 then the size is reset to 32 from 64.
18236 2006-10-31 Vincent Celier <celier@adacore.com>
18238 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18239 its file has already been loaded, according to the unit being loaded,
18240 not to the current value of Multiple_Unit_Index.
18242 2006-10-31 Thomas Quinot <quinot@adacore.com>
18243 Eric Botcazou <ebotcazou@adacore.com>

18278 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18280 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18281 Process_Body_Clauses): If the context of a body includes a use clause
18282 for P.Q then a with_clause for P in the same body is not redundant,
18283 even if the spec also has a with_clause on P.
18284 Add missing continuation mark to error msg
18285 (Build_Limited_Views): A limited view of a type is tagged if its
18286 declaration includes a record extension.
18287 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18288 node, even if the subunit has errors. This avoids malfunction by
18289 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18290 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18291 generation of obsolescent messages for with statements (cannot do
18292 this too early, or we cannot implement avoiding the messages in the
18293 case of obsolescent units withing obsolescent units).
18294 (Install_Siblings): If the with_clause is on a remote descendant of
18295 an ancestor of the current compilation unit, find whether there is
18296 a sibling child unit that is immediately visible.
18297 (Remove_Private_With_Clauses): New procedure, invoked after completing
18298 the analysis of the private part of a nested package, to remove from
18299 visibility the private with_clauses of the enclosing package
18301 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18302 now centralized in Generate_Reference.
18303 (Install_Limited_Context_Clauses): Remove superfluous error
18304 message associated with unlimited view visible through use
18305 and renamings. In addition, at the point in which the error
18306 is reported, we add the backslash to the text of the error
18307 to ensure that it is reported as a single error message.
18308 Use new // insertion for some continuation messages
18309 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18310 to create implicit with_clause for parent unit mentioned in original
18311 limited_with_clause.
18312 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18313 unit is a child unit. For ASIS queries.
18314 (Analyze_Subunit): If the subunit appears within a child unit, make all
18315 ancestor child units directly visible again.

18330 a formal object declaration with an access definition or a subtype mark
18331 with a null exclusion.
18332 (P_Generic_Association): Handle association with box, and others_choice
18333 with box, to support Ada 2005 partially parametrized formal packages.
18335 2006-10-31 Robert Dewar <dewar@adacore.com>
18336 Javier Miranda <miranda@adacore.com>
18338 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18339 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18340 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18341 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18342 private extensions.
18343 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18344 to P_Interface_Type_Definition.
18345 (P_Interface_Type_Definition): Addition of one formal to report an error
18346 if the reserved word abstract has been previously found.
18347 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18348 object renaming declaration with an access definition or subtype mark
18349 with a possible null exclusion.
18351 * par-ch9.adb: Minor error msg fix
18353 * par-load.adb: Add missing continuation mark to error msg

18371 2006-10-31 Vincent Celier <celier@adacore.com>
18373 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18374 on VMS, change "__" to '.' before checking the name.
18375 (Record_Ada_Source): Always add the source file name in the list of
18376 of sources, even if it is not the first time, as it is for another
18378 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18379 dot, instead of replacing only the first '_'.
18381 * prj-part.adb (Parse): Convert project file path to canonical form
18383 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18384 extended, the project id of the project extending it is recorded in its
18385 data, even when it has already been processed as an imported project.
18387 2006-10-31 Robert Dewar <dewar@adacore.com>
18389 * repinfo.adb (List_Entities): Don't list entities from renaming
18392 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18393 Robert Dewar <dewar@adacore.com>
18395 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18396 only a restriction warning is active for the given restriction. This is
18397 desirable because we do not want to modify code in the case where only
18399 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18400 causes overriding of real restrictions.
18401 Take advantage of new No_Restrictions constant.
18403 * raise.h: (__gnat_set_globals): Change profile.
18405 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18407 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18410 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18411 Move all the entities in obsolete package System.PolyORB_Interface to
18412 System.Partition_Interface.

18428 Gary Dismukes <dismukes@adacore.com>
18430 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18431 properly an attempt to apply Unchecked_Access to a protected operation.
18432 (OK_Self_Reference): New subprogram to check the legality of an access
18433 attribute whose prefix is the type of an enclosing aggregate.
18434 Generalizes previous mechanism to handle attribute references nested
18435 arbitrarily deep within the aggregate.
18436 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18437 can appear in an aggregate if this is a default-initialized aggregate
18438 for a self-referential type.
18439 (Resolve_Attribute, case Access): Ditto.
18440 Add support for new implementation defined attribute Stub_Type.
18441 (Eval_Attribute, case Attribute_Stub_Type): New case.
18442 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18443 (Stream_Attribute_Available): Implement using new subprogram from
18444 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18445 Has_Specified_Stream_Attribute flag.
18446 Disallow Storage_Size and Storage_Pool for access to subprogram
18447 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18448 access types of return subtypes in extended return statements. Remove
18449 accessibility checks on anonymous access types when Unchecked_Access is
18451 (Analyze_Attribute): Add support for the use of 'Class to convert
18452 a class-wide interface to a tagged type.
18453 Add support for the attribute Priority.
18454 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18455 whether the designated type is discriminated with a constrained partial
18456 view and require static matching in that case.
18457 Add local variable Des_Btyp. The Designated_Type
18458 of an access to incomplete subtype is either its non-limited view if
18459 coming from a limited with or its etype if regular incomplete subtype.
18461 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18462 Fix predicate to identify and allow cases of (expander-generated)
18463 references to tag of designated object of a RACW.
18464 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18465 non-static, and therefore cannot appear as a primary in a preelaborable
18467 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18468 Has_Read_Write_Attributes.
18469 (Has_Read_Write_Attributes): Reimplement in termes of
18470 Has_Stream_Attribute_Definition.
18471 (Missing_Read_Write_Attributes): When checking component types in a
18472 record, unconditionally call Missing_Read_Write_Attributes recursively
18473 (remove guard checking for Is_Record_Type / Is_Access_Type).
18475 2006-10-31 Robert Dewar <dewar@adacore.com>
18477 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18478 useless assignments here and conditionalize it on absence of exception
18480 (Analyze_Exception_Handlers): Small code reorganization of error
18481 detection code, for new handling of formal packages.
18483 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18484 Hristian Kirtchev <kirtchev@adacore.com>
18486 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18487 that has been constant-folded, preserve information of original tree,
18489 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18490 generated private extension declaration if the formal derived type is
18491 synchronized. Carry synchronized present over to the generated private
18493 (Validate_Derived_Type_Instance): Ensure that the actual of a
18494 synchronized formal derived type is a synchronized tagged type.
18495 (Instantiate_Formal_Package): When creating the instantiation used to
18496 validate the actual package of a formal declared without a box, check
18497 whether the formal itself depends on a prior actual.
18498 (Instantiate_Formal_Subprogram): Create new entities for the defining
18499 identifiers of the formals in the renaming declaration, for ASIS use.
18500 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18501 a renaming declaration or a subtype declaration for an actual in an
18502 instance, capture location information of declaration in generic, for
18504 (Instantiate_Formal_Package): Add comments on needed additional tests.
18505 AI-317 (partial parametrization) is fully implemented.
18506 (Validate_Private_Type_Instance): Add check for actual which
18507 must have preelaborable initialization
18508 Use new // insertion for some continuation messages
18509 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18510 Default_Expression. Add type retrieval when the declaration has an
18511 access definition. Update premature usage of incomplete type check.
18512 (Check_Access_Definition): New subsidiary routine. Check whether the
18513 current compilation version is Ada 05 and the supplied node has an
18515 (Instantiate object): Alphabetize local variables. Handle the creation
18516 of new renaming declarations with respect to the kind of definition
18517 used - either an access definition or a subtype mark. Guard against
18518 unnecessary error message in the context of anonymous access types after
18519 they have been resolved. Add check for required null exclusion in a
18520 formal object declaration.
18521 (Switch_View): A private subtype of a non-private type needs to be
18522 switched (the base type can have been switched without its private
18523 dependents because of the last branch of Check_Private_View.
18524 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18526 (Instantiate_Type): Emit an error message whenever a class-wide type of
18527 a tagged incomplete type is used as a generic actual.
18528 (Find_Actual_Type): Extend routine to handle a component type in a child
18529 unit that is imported from a formal package in a parent.
18530 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18531 agree on constrainedness, rather than checking against ultimate ancestor
18532 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18533 generic body, for navigation purposes.
18535 2006-10-31 Robert Dewar <dewar@adacore.com>
18536 Thomas Quinot <quinot@adacore.com>
18538 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18540 (New_Stream_Subprogram): When processing an attribute definition clause
18541 for a stream-oriented subprogram, record an entity node occurring at
18542 the point of clause to use for checking the visibility of the clause,
18543 as defined by 8.3(23) as amended by AI-195.
18544 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18545 New_Stream_Function and New_Stream_Procedure.
18546 (New_Stream_Function, New_Stream_Procedure): Removed.
18547 (Analyze_Attribute_Definition_Clause, case Address): Check new
18548 Alignment_Check check
18550 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18551 Javier Miranda <miranda@adacore.com>
18552 Robert Dewar <dewar@adacore.com>
18554 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18555 generate the same errors compiling under -gnatc.
18556 (Try_Object_Operation): If no candidate interpretation succeeds, but
18557 there is at least one primitive operation with the right name, report
18558 error in call rather than on a malformed selected component.
18559 (Analyze_Selected_Component): If the prefix is an incomplete type from
18560 a limited view, and the full view is available, use the full view to
18561 determine whether this is a prefixed call to a primitive operation.
18562 (Operator_Check): Verify that a candidate interpretation is a binary
18563 operation before checking the type of its second formal.
18564 (Analyze_Call): Add additional warnings for function call contexts not
18566 (Analyze_Allocator): Move the check for "initialization not allowed for
18567 limited types" after analyzing the expression. This is necessary,
18568 because OK_For_Limited_Init looks at the structure of the expression.
18569 Before analysis, we don't necessarily know what sort of expression it
18570 is. For example, we don't know whether F(X) is a function call or an
18571 indexed component; the former is legal in Ada 2005; the latter is not.
18572 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18573 were missing. We also didn't handle qualified expressions. Now also
18574 allow function calls. Use new common routine OK_For_Limited_Init.
18575 (Analyze_Type_Conversion): Do not perform some legality checks in an
18576 instance, because the error message will be redundant or spurious.
18577 (Analyze_Overloaded_Selected_Component): Do not do style check when
18578 setting an entity, since we do not know it is the right entity yet.
18579 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18580 (Analyze_Overloaded_Selected_Component): Same change
18581 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18582 since regular incomplete subtypes are transformed into corresponding
18583 subtypes of their full views.
18584 (Complete_Object_Operation): Treat name of transformed subprogram call
18585 as coming from source, for browsing purposes.
18586 (Try_Primitive_Operation): If formal is an access parameter, compare
18587 with base type of object to determine whether it is a primitive
18589 (Operator_Check): If no interpretation of the operator matches, check
18590 whether a use clause on any candidate might make the operation legal.
18591 (Try_Class_Wide_Operation): Check whether the first parameter is an
18592 access type whose designated type is class-wide.
18594 2006-10-31 Robert Dewar <dewar@adacore.com>
18595 Ed Schonberg <schonberg@adacore.com>
18596 Gary Dismukes <dismukes@adacore.com>

18599 warn on infinite loops.
18600 Add \\ to some continuation messages
18601 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18602 (Process_Bounds): If the bounds are integer literals that result from
18603 constant-folding, and they carry a user-defined type, preserve that type
18604 rather than treating this as an integer range.
18605 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18606 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18607 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18608 left hand side of assignment.
18609 (Analyze_Assignment): Add suport to manage assigments to the attribute
18610 priority of a protected object.
18611 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18612 not just identifiers.
18613 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18614 or AND THEN for possible tracking.
18615 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18616 case of while loops so we can track values in the loop body.
18618 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18619 Hristian Kirtchev <kirtchev@adacore.com>
18620 Bob Duff <duff@adacore.com>
18622 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18623 procedure cannot be a protected operation (it is a basic_declaration,
18624 not a subprogram_declaration).
18625 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18626 Subp. Add logic for entry processing.
18627 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18628 Determine whether an entry or subprogram of a protected or task type
18629 override an inherited primitive of an implemented interface.
18630 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18631 Update the actual used in calls to Check_Overriding_Indicator.
18632 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18633 generate the proper reference to the parent unit, for cross-reference.
18634 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18636 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18637 (Add_Extra_Formal): Revise procedure to allow passing in associated
18638 entity, scope, and name suffix, and handle setting of the new
18639 Extra_Formals field.
18640 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18641 pass new parameters. Add support for adding the new extra access formal
18642 for functions whose calls are treated as build-in-place.
18643 (Analyze_A_Return_Statement): Correct casing in error message.
18644 Move Pop_Scope to after Analyze_Function_Return, because an extended
18645 return statement really is a full-fledged scope. Otherwise, visibility
18646 doesn't work right. Correct use of "\" for continuation messages.
18647 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18648 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18649 the node doesn't get properly marked as analyzed.
18650 (Analyze_Subprogram_Body): If subprogram is a function that returns
18651 an anonymous access type that denotes a task, build a Master Entity
18653 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18654 proper usage of null exclusion in a result definition.
18655 (Process_Formals): Code cleanup and new error message.
18656 (Process_Formals): Detect incorrect application of null exclusion to
18658 (Conforming_Types): Handle conformance between [sub]types and itypes
18659 generated for entities that have null exclusions applied to them.
18660 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18661 base type is an access subtype. This case arrises with null exclusions.
18662 (New_Overloaded_Entity): Do not remove the overriden entity from the
18663 homonym chain if it corresponds with an abstract interface primitive.
18664 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18665 call to the synthesized predicate Is_Incomplete_Type.
18666 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18668 (Analyze_Subprogram_Declaration): Check that abstract interface
18669 primitives are abstract or null.
18670 (Analyze_Subprogram_Specification): Remove previous check for abstract
18671 interfaces because it was not complete.
18672 (Has_Interface_Formals): Removed.
18674 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18675 Javier Miranda <miranda@adacore.com>
18677 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18678 of Analyze_Package_Body, to create Itype references for anonymous
18679 access types created in the package declaration, whose designated types
18680 may have only a limited view.
18681 (Analyze_Package_Specification): For the private part of a nested
18682 package, install private_with_clauses of enclosing compilation unit if
18683 we are in its visible part.
18684 (Declare_Inherited_Private_Subprograms): Complete barrier
18685 to ensure that the primitive operation has an alias to some parent
18686 primitive. This is now required because, after the changes done for the
18687 implementation of abstract interfaces, the contents of the list of
18688 primitives has entities whose alias attribute references entities of
18689 such list of primitives.
18690 (Analyze_Package_Specification): Simplify code that handles parent units
18691 of instances and formal packages.
18692 (Uninstall_Declarations): Check the convention consistency among
18693 primitive overriding operations of a tagged record type.

18702 expected and found set right)
18703 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18704 (Analyze_Generic_Renaming): Same fix
18705 (Use_One_Package): Do not take into account the internal entities of
18706 abstract interfaces during the analysis of entities that are marked
18707 as potentially use-visible.
18708 (Find_Type): Handle the case of an attribute reference for
18709 implementation defined attribute Stub_Type (simply let the analysis of
18710 the attribute reference rewrite it).
18711 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18712 type that appears in a Use_Type clause.
18713 (Analyze_Object_Renaming): Add support for renaming of the Priority
18715 (Find_Type): In Ada 2005, a task type can be used within its own body,
18716 when it appears in an access definition.
18717 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18718 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18719 in a formal object declaration or in a subtype declaration.
18720 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18721 (Check_Null_Exclusion): New local routine to
18722 Analyze_Subprogram_Renaming. Check whether the formals and return
18723 profile of a renamed subprogram have required null exclusions when
18724 their counterparts of the renaming already impose them.
18725 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18726 Determine whether an entity is inside a generic scope.
18727 (In_Open_Scope): First pass of documentation update.
18728 (Find_Expanded_Name): Add support for shadow entities associated with
18729 limited withed packages. This is required to handle nested packages.
18730 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18731 that makes a renaming of a limited withed package illegal.

18736 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18737 Check_Overriding_Indicator.
18738 (Analyze_Task_Definition): Ditto.
18739 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18740 (Check_Overriding_Indicator): To find overridden interface operation,
18741 examine only homonyms that have an explicit subprogram declaration, not
18742 inherited operations created by an unrelated type derivation.
18743 (Check_Overriding_Indicator): When checking for the presence of "null"
18744 in a procedure, ensure that the queried node is a procedure
18746 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18747 type when the formal is an access to variable.
18748 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18749 (Analyze_Task_Type): Same addition
18750 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18758 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18759 inherited from an interface ancestor by another interface in the
18760 context of an instance as 'late'.
18761 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18762 of a call to a function that dispatches on access result.
18763 (Check_Dispatching_Operation): In case of late overriding of a primitive
18764 that covers abstract interface subprograms we register it in all the
18765 secondary dispatch tables associated with abstract interfaces.
18766 (Check_Dispatching_Call): Add check that a dispatching call is not made
18767 to a function with a controlling result of a limited type. This is a
18768 current implementation restriction.
18769 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18770 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18771 argument is an interface type that is a generic formal.
18772 (Is_Interface_Subprogram): Removed.
18773 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18774 operation, check the formals to handle the case in which it is
18775 associated with an abstract interface type.
18777 2006-10-31 Robert Dewar <dewar@adacore.com>
18778 Ed Schonberg <schonberg@adacore.com>
18780 * sem_elab.ads, sem_elab.adb (Check_Elab_Assign): New procedure

18792 Hristian Kirtchev <kirtchev@adacore.com>
18793 Javier Miranda <miranda@adacore.com>
18795 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18796 subprogram type to provide better diagnostics in case of ambiguity.
18797 (Covers): Handle coverage of formal and actual anonymous access types in
18798 the context of generic instantiation.
18799 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18800 abstract interface types; this is required to handle concurrent types
18801 with discriminants and abstract interface types.
18802 (Covers): Include type coverage of both regular incomplete subtypes and
18803 incomplete subtypes of incomplete type visibles through a limited with

18817 qualification from an expression. There are numerous places where this
18818 ought to be used, but we currently only deal properly with zero or one
18820 (In_Instance); The analysis of the actuals in the instantiation of a
18821 child unit is not within an instantiation, even though the parent
18822 instance is on the scope stack.
18823 (Safe_To_Capture_Value): Exclude the case of variables that are
18825 (Check_Obsolescent): Removed
18826 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18846 objects to handle the Ada 2005 case, where aliasedness no longer implies
18847 that the object is constrained. In particular, for dereferenced names,

18904 (N_Extended_Return_Statement): New node for extended_return_statement
18906 (N_Return_Object_Declaration): New node for part of

19588 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19589 abstract interface type, the static analysis is not enough to know if

19591 we must pass the work to the expander to generate the required code to
19592 evaluate the conversion at run-time.
19593 (Resolve_Equality_Op): Do not apply previous
19594 transformation if expansion is disasbled, to prevent anomalies when

20268 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20269 were not always properly handled previously.
20270 Since we are changing the tree format anyway, also get rid of the
20271 junk obsolete Immediate_Errors flag.
20272 (Tree_Read): Change the way of reading Tree_Version_String - now we
20273 read the version string from the tree even if its length is not the
20274 same as the length of the version string computed from Gnatvsn.
20275 (Search_Directory_Present): New Boolean flag for the compiler.
20276 Define Tree_Version_String as a dynamic string.
20277 (Default_Stack_Size): new variable, used to handle switch -d.
20280 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20281 only for main unit.
20282 Add pragma Ada_2005 (synonym for Ada_05)
20283 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20284 were not always properly handled previously.
20286 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20287 explicit Ada_95 to Ada_2005.
20289 2006-02-13 Javier Miranda <miranda@adacore.com>
20290 Robert Dewar <dewar@adacore.com>
20291 Ed Schonberg <schonberg@adacore.com>
20293 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20294 against errors in the source program: a private types for which the
20295 corresponding full type declaration is missing and pragma CPP_Virtual
20297 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20298 (Is_Known_Null): New flag
20299 (Has_Pragma_Pure): New flag
20300 (No_Return): Present in all entities, set only for procedures
20301 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20302 explicitly declared limited.
20303 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20304 entities. Only used for component marked Is_Tag. If present it stores
20305 the Offset_To_Top function used to provide this value in tagged types
20306 whose ancestor has discriminants.
20308 * exp_ch2.adb: Update status of new Is_Known_Null flag
20310 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20312 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20313 the categorization sense if Is_Pure was set by pragma Pure_Function.
20315 2006-02-13 Quentin Ochem <ochem@adacore.com>
20316 Olivier Hainque <hainque@adacore.com>
20318 * bindusg.adb: Updated documentation for -d and -D switches.
20320 * raise.h (__gnat_set_globals): added new parameter for
20321 Default_Stack_Size.
20323 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20324 (__gnat_handle_vms_condition): Adjust context before raise.
20325 (__gnat_install_handler): Restore the global vector setup for GCC
20326 versions before 3.4, as the frame based circtuitry is not available
20328 (__gnat_set_globals): added a parameter default_stack_size
20329 (__gl_default_stack_size): new variable.
20331 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20333 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20334 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20335 does not exist in the Ada RM.
20336 (Compatible_Int_Bounds): Determine whether two integer range bounds
20337 are of equal length and have the same start and end values.
20338 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20339 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20340 aggregate when it is part of an object declaration.
20341 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20342 constrains discriminants of its parent, add explicitly the discriminant
20343 constraints of the ancestor by retrieving them from the
20344 stored_constraint of the parent.
20346 2006-02-13 Robert Dewar <dewar@adacore.com>
20348 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20349 attribute Mechanism_Code is applied to renamed subprogram, modify
20350 prefix to point to base subprogram.
20351 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20353 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20354 renamed subprograms so that the front-end must replace the prefix
20357 2006-02-13 Javier Miranda <miranda@adacore.com>
20358 Gary Dismukes <dismukes@adacore.com>
20360 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20361 availability of RE_Interface_Tag.
20362 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20363 (Freeze_Record_Type): Do not generate the tables associated with
20364 timed and conditional dispatching calls through synchronized
20365 interfaces if compiling under No_Dispatching_Calls restriction.
20366 When compiling for Ada 2005, for a nonabstract
20367 type with a null extension, call Make_Controlling_Function_Wrappers
20368 and insert the wrapper function declarations and bodies (the latter
20369 being appended as freeze actions).
20370 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20371 predefined primitives associated with timed and conditional
20372 dispatching calls through synchronized interfaces if we are
20373 compiling under No_Dispatching_Calls.
20374 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20375 service is available before generating a call.
20376 (Make_Controlling_Function_Wrappers): New procedure.
20377 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20378 access-to-limited-interfaces because they can be used to reference
20379 tasks that implement such limited interface.
20380 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20381 procedure spec and body of the Offset_To_Top function that is generated
20382 when the parent of a type with discriminants has secondary dispatch
20384 (Init_Secondary_Tags): Handle the case in which the parent of the type
20385 containing secondary dispatch tables has discriminants to generate the
20386 correct arguments to call Set_Offset_To_Top.
20387 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20389 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20390 Add Wide_[Wide_]Expanded_Name.
20391 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20392 the same functionality of Get_Prim_Op_Address but applied to predefined
20393 primitive operations because the pointers to the predefined primitives
20394 are now saved in a separate table.
20395 (Parent_Size): Modified to get access to the separate table of primitive
20396 operations or the parent type.
20397 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20398 functionality of Set_Prim_Op_Address but applied to predefined primitive
20400 (Set_Signature): New subprogram used to store the signature of a DT.
20401 (Displace): If the Offset_To_Top value is not static then call the
20402 function generated by the expander to get such value; otherwise use
20403 the value stored in the table of interfaces.
20404 (Offset_To_Top): The type of the actual has been changed to Address to
20405 give the correct support to tagged types with discriminants. In this
20406 case this value is stored just immediately after the tag field.
20407 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20408 offset_to_top value is static and hence pass this value to the run-time
20409 to store it in the table of interfaces, or else if this value is dynamic
20410 and then pass to the run-time the address of a function that is
20411 generated by the expander to provide this value for each object of the
20414 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20415 (Default_Prim_Op_Count): New entity
20416 (Get_Predefined_Prim_Op_Address): New entity
20417 (Set_Predefined_Prim_Op_Address): New entity
20418 (RE_Set_Signature): New entity
20420 2006-02-13 Thomas Quinot <quinot@adacore.com>
20421 Ed Schonberg <schonberg@adacore.com>
20423 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20424 Make_Adjust_Call done for a newly-allocated object.
20426 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20427 in a subprogram are wrapped in a cleanup block, indicate that the
20428 subprogram contains an inner block with an exception handler.
20429 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20430 Adjust call is for a newly-allocated object. In that case we must not
20431 assume that the finalization list chain pointers are correct (since they
20432 come from a bit-for-bit copy of the original object's pointers) so if
20433 the attach level would otherwise be zero (no change), we set it to 4
20434 instead to cause the pointers to be reset to null.
20436 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20437 reset chain pointers to null.
20439 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20441 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20442 string, and the context requires a loop for the assignment (e.g.
20443 because the left-hand side is packed), generate a unique name for the
20444 temporary that holds the string, to prevent spurious name clashes.
20446 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20447 Javier Miranda <miranda@adacore.com>
20448 Robert Dewar <dewar@adacore.com>
20449 Gary Dismukes <dismukes@adacore.com>
20451 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20452 return unconstrained arrays.
20454 (Expand_Call): An indirect call through an access parameter of a
20455 protected operation is not a protected call.
20456 Add circuit to raise CE in Ada 2005 mode following call
20457 to Raise_Exception.
20458 (Register_DT_Entry): Do nothing if
20459 the run-time does not give support to abstract interfaces.
20460 (Freeze_Subprogram): In case of dispatching operations, do not generate
20461 code to register the operation in the dispatch table if the source
20462 is compiled with No_Dispatching_Calls.
20463 (Register_Predefined_DT_Entry): Generate code that calls the new
20464 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20465 Set_Prim_Op_Address.
20467 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20468 on array assignments if the right-hand side is a function call that has
20469 been inlined. Check is performed on the assignment in the block.
20470 (Process_Bounds): If bounds and range are overloaded, apply preference
20471 rule for root operations to disambiguate, and diagnose true ambiguity.
20472 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20473 a tag-indeterminate right-hand side even when Expander_Active is True.
20474 Needed to ensure that dispatching calls to T'Input are allowed and
20475 get the tag of the target class-wide object.
20477 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20478 an inherited primitive operation that already overrides several
20479 abstract interface primitives. For transitivity, the new entity must
20480 also override all the abstract interface primitives covered by the
20481 inherited overriden primitive.
20482 Emit warning if new entity differs from homograph in same scope only in
20483 that one has an access parameter and the other one has a parameter of
20484 a general access type with the same designated type, at the same
20485 position in the signature.
20486 (Make_Inequality_Operator): Use source locations of parameters and
20487 subtype marks from corresponding equality operator when creating the
20488 tree structure for the implicit declaration of "/=". This does not
20489 change anything in behaviour except that the decoration of the
20490 components of the subtree created for "/=" allows ASIS to get the
20491 string images of the corresponding identifiers.
20492 (Analyze_Return_Statement): Remove '!' in warning message.
20493 (Check_Statement_Sequence): Likewise.
20494 (Analyze_Subprogram_Body): For an access parameter whose designated type
20495 is an incomplete type imported through a limited_with clause, use the
20496 type of the corresponding formal in the body.
20497 (Check_Returns): Implicit return in No_Return procedure now raises
20498 Program_Error with a compile time warning, instead of beging illegal.
20499 (Has_Single_Return): Function returning unconstrained type cannot be
20500 inlined if expression in unique return statement is not an identifier.
20501 (Build_Body_To_Inline): It is possible to inline a function call that
20502 returns an unconstrained type if all return statements in the function
20503 return the same local variable. Subsidiary procedure Has_Single_Return
20504 verifies that the body conforms to this restriction.
20506 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20507 same type, and one of them is of an anonymous access type, convert
20508 the other operand to it, so that this is a valid binary operation for
20510 (Resolve_Type_Conversion): Handle subtypes of protected types and
20511 task types when accessing to the corresponding record type.
20512 (Resolve_Allocator): Add '\' in 2-line warning message.
20513 Remove '!' in warning message.
20514 (Resolve_Call): Add '\' in 2-line warning message.
20515 (Valid_Conversion): Likewise.
20516 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20517 resulting type may be an access type with an implicit dereference.
20518 Obtain the proper component from the designated type.
20519 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20520 given by an expanded name with prefix Standard, when the operands are
20521 of an anonymous access type.
20522 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20523 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20524 prefix of the expression is not of an incomplete type. Allows full
20525 diagnoses of all semantic errors.
20526 (Resolve_Actuals): If the actual is an allocator whose directly
20527 designated type is a class-wide interface we build an anonymous
20528 access type to use it as the type of the allocator. Later, when
20529 the subprogram call is expanded, if the interface has a secondary
20530 dispatch table the expander will add a type conversion to force
20531 the displacement of the pointer.
20532 (Resolve_Call): If a function that returns an unconstrained type is
20533 marked Inlined_Always and inlined, the call will be inlined and does
20534 not require the creation of a transient scope.
20535 (Check_Direct_Boolean_Op): Removed
20536 (Resolve_Comparison_Op): Remove call to above
20537 (Resolve_Equality_Op): Remove call to above
20538 (Resolve_Logical_Op): Inline above, since this is only call.
20539 (Valid_Conversion): Handle properly conversions between arrays of
20540 convertible anonymous access types.
20543 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20544 the literal in an unchecked conversion, because GCC 4.x needs a static
20545 value for a string bound.
20547 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20548 Hristian Kirtchev <kirtchev@adacore.com>
20550 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20551 components of the corresponding record, take into account component
20552 definitions that are access definitions.
20553 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20554 procedure is not considered a dispatching call and will be expanded
20557 2006-02-13 Javier Miranda <miranda@adacore.com>
20559 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20560 controlling argument of the dispatching call is an abstract interface
20561 class-wide type then we use it directly.
20562 Check No_Dispatching_Calls restriction.
20563 (Default_Prim_Op_Position): Remove the code that looks for the last
20564 entity in the list of aliased subprograms. This code was wrong in
20566 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20567 when the source is compiled with the No_Dispatching_Calls restriction.
20568 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20569 if we are compiling with restriction No_Dispatching_Calls.
20570 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20571 subprograms if we are compiling under No_Dispatching_Calls restriction.
20572 (Make_DT): Generate a dispatch table with a single dummy entry if
20573 we are compiling with the No_Dispatching_Calls restriction. In
20574 addition, in this case we don't generate code that calls to the
20575 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20576 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20577 of this subprogram if compiling with the No_Dispatching_Calls
20579 (Expand_Type_Conversion): Instead of using the actual parameter,
20580 the argument passed as parameter to the conversion function was
20581 erroneously referenced by the expander.
20582 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20583 Set_Predefined_Primitive_Op_Address and Set_Signature.
20584 (Expand_Dispatching_Call): Generate call to
20585 Get_Predefined_Prim_Op_Address for predefined primitives.
20586 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20587 predefined primitives.
20588 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20589 primitives we reserve one dummy entry to ensure that the tag does not
20590 point to some memory that is associated with some other object. In
20591 addition, remove all the old code that generated the assignments
20592 associated with the signature of the dispatch table and replace them
20593 by a call to the new subprogram Set_Signature.
20594 (Set_All_DT_Position): Change the algorithm because now we have a
20595 separate dispatch table associated with predefined primitive operations.
20596 (Expand_Interface_Conversion): In case of non-static offset_to_top
20597 add explicit dereference to get access to the object after the call
20598 to displace the pointer to the object.
20599 (Expand_Interface_Thunk): Modify the generation of the actual used
20600 in the calls to the run-time function Offset_To_Top to fulfil its
20602 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20604 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20606 * exp_dist.adb (Copy_Specification): For access parameters, copy
20607 Null_Exclusion flag, which will have been set for stream subprograms
20610 2006-02-13 Pascal Obry <obry@adacore.com>
20612 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20613 previous implementation was using the C runtime spawnve routine but
20614 the corresponding wait was using directly the Win32 API. This was
20615 causing some times a lock when waiting for an event using
20616 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20617 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20618 API fixes this problem.
20620 2006-02-13 Robert Dewar <dewar@adacore.com>
20622 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20625 2006-02-13 Thomas Quinot <quinot@adacore.com>

20629 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20630 array reference that is an explicit dereference, mark the converted
20631 (packed) array reference as analyzed to prevent a forthcoming
20632 reanalysis from resetting its type to the original (non-packed) array
20635 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20636 Javier Miranda <miranda@adacore.com>
20637 Eric Botcazou <ebotcazou@adacore.com>
20639 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20640 Is_Predefined_Primitive_Operation): When
20641 searching for the predefined equality operator, verify that operands
20642 have the same type.
20643 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20644 for the last entity in the list of aliased subprograms. This code
20645 was wrong in case of renamings.
20646 (Set_Renamed_Subprogram): New procedure
20647 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20648 Exp_Type constant computed when entering this subprogram.
20649 (Known_Null): New function
20650 (OK_To_Do_Constant_Replacement): New function
20651 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20652 (Side_Effect_Free): An attribute reference 'Input is not free of
20653 side effect, unlike other attributes that are functions. (from code
20655 (Remove_Side_Effects): Expressions that involve packed arrays or records
20656 are copied at the point of reference, and therefore must be marked as
20657 renamings of objects.
20658 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20659 not a dispatching operation.
20662 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20663 elementary types in all cases.
20665 2006-02-13 Javier Miranda <miranda@adacore.com>
20667 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20668 task types when accessing to the corresponding record type.
20669 Remove '!' in warning message.
20671 2006-02-13 Olivier Hainque <hainque@adacore.com>
20673 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20674 to avoid useless and space inefficient overalignments on targets where
20675 Max_Alignment is larger than 16.
20677 2006-02-13 Pascal Obry <obry@adacore.com>
20679 * g-catiio.adb (Sec_Number): New type used to compute the number of
20680 seconds since 1-1-1970.
20681 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20682 negative numbers (years, months...) it is better to have a Natural here.
20684 (Image) [Number]: Change parameter from Long_Integer to Number.
20685 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20686 overflow for dates past year 2038.
20688 2006-02-13 Matthew Heaney <heaney@adacore.com>
20690 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20693 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20695 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20697 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20698 finalization can occur normally.
20700 2006-02-13 Vincent Celier <celier@adacore.com>
20702 * gnatcmd.adb (Rules_Switches): New table
20703 (Add_To_Rules_Switches): New procedure
20704 (GNATCmd): For command CHECK, put all options following "-rules" in the
20705 Rules_Switches table. Append these -rules switches after the -cargs
20708 2006-02-13 Robert Dewar <dewar@adacore.com>
20710 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20711 These two cases were generating incorrect output, and if this unit
20712 was built with checks on, generated a discriminant mismatch constraint
20715 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20716 Robert Dewar <dewar@adacore.com>
20718 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20719 view is an array type, indicate the component type as well, for
20720 navigation purposes.
20721 (Generate_Reference): Don't consider array ref on LHS to be a case

20723 Do not give Ada 2005 warning except on real reference.
20725 2006-02-13 Vincent Celier <celier@adacore.com>
20727 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20728 main source, add switch -mdebug-main=_ada_ so that the executable can
20729 be debugged by the standard VMS debugger.
20730 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20731 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20732 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20733 of the last source, as the binding and linking phases are never
20735 Set all executable obsolete when rebuilding a library.
20737 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20740 2006-02-13 Javier Miranda <miranda@adacore.com>

20744 code to improve the error message reported when the program has
20745 declarations of abstract interface types and it is not compiled with
20746 the -gnat05 switch.
20747 (P_Access_Definition): Reorganize the code to improve the error
20748 message reported when the new Ada 2005 syntax for anonymous
20749 access types is used and the program is not compiled with the

20780 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20783 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20784 Call Prj.Proc.Process with parameter When_No_Sources.
20786 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20787 Call Recursive_Check with parameter When_No_Sources.

20813 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20814 aliased entities to look for the overriden abstract interface
20816 (Is_Interface_Subprogram): Complete documentation.
20817 (Check_Dispatching_Operation): Do not generate code to register the
20818 operation in the dispatch table if the source is compiled with
20819 restriction No_Dispatching_Calls.

20821 No_Return procedure with procedure that is not No_Return
20822 (Check_Dispatching_Call): Suppress the check for an abstract operation
20823 when the original node of an actual is a tag-indeterminate attribute
20824 call, since the attribute, which must be 'Input, can never be abstract.
20825 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20826 call to the Input attribute (even when rewritten).
20827 (Propagate_Tag): Augment comment to indicate the possibility of a call
20828 to an Input attribute.
20830 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20840 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20842 2006-02-13 Javier Miranda <miranda@adacore.com>
20844 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20845 handles default-initialized components to keep separate the management
20846 of this feature but also avoid the unrequired resolution and
20847 expansion of components that do not have partially initialized
20849 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20850 (Check_Bounds): Likewise.
20851 (Check_Length): Likewise.
20853 2006-02-13 Javier Miranda <miranda@adacore.com>
20854 Ed Schonberg <schonberg@adacore.com>
20856 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20857 abstract interface type call analyze_and_resolve to expand the type
20858 conversion into the corresponding displacement of the
20859 reference to the base of the object.
20860 (Eval_Attribute, case Width): For systems where IEEE extended precision
20861 is supported, the maximum exponent occupies 4 decimal digits.
20862 (Accessibility_Message): Add '\' in 2-line warning message.
20863 (Resolve_Attribute): Likewise.
20864 (case Attribute_Access): Significantly revise checks
20865 for illegal access-to-subprogram Access attributes to properly enforce
20866 the rules of 3.10.2(32/2).
20867 Diagnose use of current instance with an illegal attribute.
20869 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20871 (Enclosing_Generic_Unit): New function to return a node's innermost
20872 enclosing generic declaration node.
20873 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20874 (Type_Access_Level): The accessibility level of anonymous acccess types
20875 associated with discriminants is that of the current instance of the
20876 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20877 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20878 (Kill_Current_Values_For_Entity): New function
20879 (Enter_Name): Change formal type to Entity_Id
20881 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>

20885 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20886 Analyze_Compilation_Unit.
20887 Detect and warn on redundant with clauses detected in a package spec
20888 and/or body when -gnatwr is used.
20889 (Analyze_Context): Analyze config pragmas before other items
20890 (Install_Context_Items): Don't analyze config pragmas here
20891 (Install_Limited_Withed_Unit): Set limited entity of package in
20892 with_clause so that cross-reference information or warning messages on
20893 unused packages can be properly generated
20894 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20895 has Error_Posted set. Prevent infinite loops in illegal programs.
20896 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20897 to the point of the error test requiring the current unit to be private.
20898 This ensures that private with clauses are not exempted from the basic
20899 checking for being a descendant of the same library unit parent as a
20900 withed private descendant unit.
20901 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20902 handle private with clauses properly, as well as to account for cases
20903 where the withed unit is a public descendant of a private ancestor
20904 (in which case the current unit must be a descendant of the private
20905 ancestor's parent). The spec comments were updated accordingly. Also,
20906 the old error message in this subprogram was replaced with error
20907 messages that mirror the errors tested and reported by
20908 Check_Private_Child_Unit.
20909 Parameter and variable names improved for readability.
20910 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20911 private as the precondition for calling
20912 Check_Private_Limited_Withed_Unit since that subprogram has been
20913 revised to test public units as well as private units.

20918 Javier Miranda <miranda@adacore.com>
20920 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20921 that Scope_Stack.First = 1.
20922 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20923 were not always properly handled previously.
20924 (Formal_Entity): Complete rewrite, to handle properly some complex case
20925 with multiple levels of parametrization by formal packages.
20926 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20927 to the corresponding derived type declaration for proper semantics.
20929 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20930 (Check_Component): Enforce restriction on components of
20931 unchecked_unions: a component in a variant cannot contain tasks or
20933 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20935 Add pragma Ada_2005 (synonym for Ada_05)
20936 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20937 were not always properly handled previously.
20938 Document that pragma Propagate_Exceptions has no effect
20939 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20940 (Set_Convention_From_Pragma): Check that if a convention is
20941 specified for a dispatching operation, then it must be
20942 consistent with the existing convention for the operation.
20943 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20944 longer required to specify an vtable-ptr component in the record. For
20945 compatibility reasons we leave the support for the previous definition.
20946 (Analyze_Pragma, case No_Return): Allow multiple arguments
20948 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20949 non-overrideen inherited operation with a controlling result as
20950 illegal only its implicit declaration comes from the derived type
20951 declaration of its result's type.
20952 (Check_Possible_Deferred_Completion): Relocate the object definition
20953 node of the subtype indication of a deferred constant completion rather
20954 than directly analyzing it. The analysis of the generated subtype will
20955 correctly decorate the GNAT tree.
20956 (Record_Type_Declaration): Check whether this is a declaration for a
20957 limited derived record before analyzing components.
20958 (Analyze_Component_Declaration): Diagnose record types not explicitly
20959 declared limited when a component has a limited type.
20960 (Build_Derived_Record_Type): Code reorganization to check if some of
20961 the inherited subprograms of a tagged type cover interface primitives.
20962 This check was missing in case of a full-type associated with a private
20964 (Constant_Redeclaration): Check that the subtypes of the partial and the
20965 full view of a constrained deferred constant statically match.
20966 (Mentions_T): A reference to the current type in an anonymous access
20967 component declaration must be an entity name.
20968 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20969 class_wide type to refer to full type, not to the incomplete one.
20970 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20971 available. Required to give support to the certified run-time.
20972 (Analyze_Component_Declaration): In case of anonymous access components
20973 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20974 (Process_Discriminants): For an access discriminant, use the
20975 discriminant specification as the associated_node_for_itype, to
20976 simplify accessibility checks.
20978 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20979 Javier Miranda <miranda@adacore.com>
20981 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20982 abstract interpretations on an operator, remove interpretations that
20983 yield Address or a type derived from it, if one of the operands is an
20985 (Try_Object_Operation.Try_Primitive_Operation,
20986 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20987 location when creating the new reference to a primitive or class-wide
20988 operation as a part of rewriting a subprogram call.
20989 (Try_Primitive_Operations): If context requires a function, collect all
20990 interpretations after the first match, because there may be primitive
20991 operations of the same type with the same profile and different return
20992 types. From code reading.
20993 (Try_Primitive_Operation): Use the node kind to choose the proper
20994 operation when a function and a procedure have the same parameter
20996 (Complete_Object_Operation): If formal is an access parameter and prefix
20997 is an object, rewrite as an Access reference, to match signature of
20998 primitive operation.
20999 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21000 by an expanded name with prefix Standard, when the operands are of an
21001 anonymous access type.
21002 (Remove_Abstract_Operations): If the operation is abstract because it is
21003 inherited by a user-defined type derived from Address, remove it as
21004 well from the set of candidate interpretations of an overloaded node.
21005 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21008 2006-02-13 Bob Duff <duff@adacore.com>
21010 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21011 redundant use clauses.
21012 In particular, if the scope of two use clauses overlaps, but one is not
21013 entirely included in the other, we should not warn. This can happen
21014 with nested packages.
21015 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21016 reported errors. The bug was reported when the compiler was built
21017 with assertions enabled.
21018 (Find_Type): If the node is a 'Class reference and the prefix is a
21019 synchronized type without a corresponding record, return the type
21022 2006-02-13 Javier Miranda <miranda@adacore.com>
21024 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21025 if this is the full-declaration associated with a private declaration
21026 that implement interfaces, then the private type declaration must be
21028 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21029 as aliased. The use of the 'access attribute is not available for such
21030 object (for this purpose the object should be explicitly marked as
21031 aliased, but being an anonymous type this is not possible).
21033 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21034 Robert Dewar <dewar@adacore.com>
21036 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21037 compilation unit is an elaboration scope.
21038 (Add_Task_Proc): Add '\' in 2-line warning message.
21039 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21041 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21042 Javier Miranda <miranda@adacore.com>
21044 * sem_type.adb (Write_Overloads): Improve display of candidate
21046 (Add_One_Interp): Do not add to the list of interpretations aliased
21047 entities corresponding with an abstract interface type that is an
21048 immediate ancestor of a tagged type; otherwise we have a dummy
21049 conflict between this entity and the aliased entity.
21050 (Disambiguate): The predefined equality on universal_access is not
21051 usable if there is a user-defined equality with the proper signature,
21052 declared in the same declarative part as the designated type.
21053 (Find_Unique_Type): The universal_access equality operator defined under
21054 AI-230 does not cover pool specific access types.
21055 (Covers): If one of the types is a generic actual subtype, check whether
21056 it matches the partial view of the other type.
21058 2006-02-13 Thomas Quinot <quinot@adacore.com>
21060 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21061 line. This is necessary to allow In_Extended_Main_Unit to provide
21062 correct results for itypes while writing out expanded source.
21063 (Close_File): No need to update the source_index_table here since it's
21064 now done for each line.
21066 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21067 Robert Dewar <dewar@adacore.com>
21069 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21070 preserve the source unit where the itype is declared, and prevent a
21072 (Note_Implicit_Run_Time_Call): New procedure
21073 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21076 * sprint.ads: Document use of $ for implicit run time routine call
21078 2006-02-13 Quentin Ochem <ochem@adacore.com>
21080 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21083 2006-02-13 Bob Duff <duff@adacore.com>
21085 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21086 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21087 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21088 raise Constraint_Error.
21090 * s-vallli.adb (Scan_Long_Long_Integer): Call
21091 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21092 do not scan leading blanks and sign twice.
21093 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21094 raise Constraint_Error.
21096 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21097 Scan_Long_Long_Unsigned): Split out most of the processing from
21098 Scan_Long_Long_Unsigned out into
21099 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21100 This prevents scanning leading blanks and sign twice.
21101 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21104 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21105 out most of the processing from Scan_Unsigned out into
21106 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21107 This prevents scanning leading blanks and sign twice.
21109 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21110 use with Modular'Value attribute.
21111 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21309 * a-taster.ads, a-taster.adb: New files.
21311 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21312 link to the version that does nothing. This way the task termination
21313 routine is not executed twice for the environment task when finishing
21314 because of an unhandled exception.
21316 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21317 handler because of an unhandled exception.
21319 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21325 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21326 non-tasking version of the soft link for task termination. We do
21327 nothing since if we are using the non-tasking version it
21328 means that the task termination functionality is not used.

21330 in charge of finalizing the global list for controlled objects.
21331 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21332 instead for handling run-time termination in a more flexible way.
21333 (Adafinal_NT): This new procedure will take care of finalizing the
21334 global list for controlled objects if needed, but no tasking
21337 * s-tarest.adb (Task_Lock): Do not try to lock again the
21338 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21339 some run-time operations.
21340 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21341 until all nested locks have been released.
21342 (Task_Wrapper): Call the fall-back task termination handler. It
21343 applies to all tasks but the environment task.
21344 (Finalize_Global_Tasks): Add the call for the task termination
21345 procedure for the environment task.
21346 (Task_Wrapper): suppress warnings around declaration of
21347 Secondary_Stack_Address.

21350 moved to the Common_ATCB record.
21351 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21352 Common_ATCB record.
21353 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21354 Common_ATCB record.
21356 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21357 Fall_Back_Handler, and Specific_Handler.
21359 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21360 defined in Ada.Task_Termination, to avoid circular dependencies.
21361 (Termination_Handler): Redefine this type here, alredy defined in
21362 Ada.Task_Termination, for avoiding circular dependencies.
21363 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21364 for storing task termination handlers. In addition,
21365 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21366 Common_ATCB because it is used by both the regular and the restricted
21368 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21369 Common_ATCB because it is used by both the regular and the restricted
21371 (Common_ATCB): Added a dynamic task analyzer field.
21373 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21374 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

21376 tasks but the environment task.
21377 (Finalize_Global_Tasks): Call the task termination procedure for the
21378 environment task. The call to Finalize_Global_List is now performed
21379 using the soft links mechanism.
21380 (Task_Wrapper): added dynamic stack analysis.
21382 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21383 potentially blocking operations has been moved from
21384 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21385 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21386 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21387 this run-time check.
21389 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21390 of task termination procedure.
21391 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21433 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21434 to the specification because the frontend generates code that uses this
21436 (Set_Interface_Table): Add missing assertion.
21437 Update documentation describing the run-time structure.
21438 (Displace): New subprogram that displaces the pointer to the object
21439 to reference one of its secondary dispatch tables.
21440 (IW_Membership): Modified to use the new table of interfaces.
21441 (Inherit_TSD): Modified to use the new table of interfaces.
21442 (Register_Interface_Tag): Use the additional formal to fill the
21443 contents of the new table of interfaces.
21444 (Set_Interface_Table): New subprogram that stores in the TSD the

21459 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21460 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21461 record component containing the tag of the secondary dispatch table we
21462 have to use the Offset_To_Top run-time function to get this information;
21463 otherwise if the pointer to the base of the object has been displace
21464 we get a wrong value if we use the 'position attribute.
21466 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21467 all the calls to Expand_Interface_Thunk.
21468 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21471 ensure that the interfaces implemented by the ancestors are placed
21472 at the header of the generated list.
21473 (Expand_Interface_Conversion): Handle the case in which the displacement
21474 associated with the interface conversion is not statically known. In
21475 this case we generate a call to the new run-time subprogram Displace.

21477 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21478 Get_Tagged_Kind and Set_Tagged_Kind.
21479 (Tagged_Kind): New function that determines the tagged kind of a type
21480 with respect to limitedness and concurrency and returns a reference to

21486 secondary dispatch table respectively of a tagged type.
21488 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21489 (Expand_Interface_Conversion): New subprogram to indicate if the
21490 displacement of the type conversion is statically known.

21502 RE_TK_Tagged, RE_TK_Task.
21504 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21505 Init_Secondary_Tags_Internal to allow its use with interface types and
21506 also to generate the code for the new additional actual required
21507 by Set_Offset_To_Top.
21508 (Build_Init_Statements): In case of components associated with abstract
21509 interface types there is no need to generate a call to its IP.
21510 (Freeze_Record_Type): Generate Select Specific Data tables only for
21512 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21513 the bodies and specifications of the predefined primitive operations
21514 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21515 for concurrent types.

21520 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21521 properly protected objects and attach handler in the case of the
21522 restricted profile.
21523 Move embeded package Select_Expansion_Utilities into a separate external

21535 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21536 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21537 about the use and expansion of SAVE_EXPRs in the various possible
21538 renaming handling cases.
21539 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21540 abusing DECL_FCONTEXT.

21633 the iterator is quitting iteration on parent directory.
21635 2005-12-09 Javier Miranda <miranda@adacore.com>
21637 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21638 and the assignment to a class-wide object, before the assignment we
21639 generate a run-time check to ensure that the tag of the Target is
21640 covered by the tag of the source.

21705 copied component does not have a known static Esize, then reset
21706 the size and positional fields of the new component.
21707 (Analyze_Component_Declaration): A limited component is
21708 legal within a protected type that implements an interface.
21709 (Collect_Interfaces): Do not add to the list the interfaces that
21710 are implemented by the ancestors.
21711 (Derived_Type_Declaration): If the parent of the full-view is an
21712 interface perform a transformation of the tree to ensure that it has
21713 the same parent than the partial-view. This simplifies the job of the
21714 expander in order to generate the correct object layout, and it is
21715 needed because the list of interfaces of the full-view can be given in
21717 (Process_Full_View): The parent of the full-view does not need to be
21718 a descendant of the parent of the partial view if both parents are
21720 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21721 "limited" the parent must be a limited type.

21733 lists of interfaces constitute a set equality. If not, the first
21734 differing interface is returned.
21735 (Process_Full_View): Improve the check for the "no hidden interface"
21736 rule as defined by AI-396.

21795 available user-specified stream attributes on limited parameters to
21796 also test the type directly rather than only its underlying type (for
21797 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21798 attributes are visible at the point of the subprogram declaration.
21799 For Ada 2005, the error message is modified to indicate that the
21800 type's stream attributes must be visible (again, only for -gnat05).

21832 types use the corresponding record type. This was not needed before
21833 the implementation of Ada 2005 synchronized types because
21834 concurrent types were never tagged types in Ada 95.

21962 * socket.c: Add extern int h_errno for rtems since networking header
21963 files are not available at this point in a tool bootstrap. Newlib

22080 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22081 elementary types using the operator in standard. It is cleaner not to
22082 modify the programmers intent, especially in the case of floating-point.

22084 it did not matter because we always rewrote a/=b to not(a=b).
22085 (Expand_Allocator_Expression): For an allocator expression whose nominal
22086 subtype is an unconstrained packed type, convert the expression to its
22087 actual constrained subtype.
22088 Implement warning for <= or >= where < or > not possible
22089 Fix to Vax_Float tests (too early in many routines, causing premature
22090 Vax_Float expansions.

22097 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22098 a string literal for precise control over warnings.
22099 Avoid raise of pragma in case of unrecognized pragma and just return

22104 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22105 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22107 Include -gnatwx as part of -gnatg (warn on redundant parens)
22108 Allow optional = after -gnatm
22109 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22110 longer sets Elaboration_Checks.
22111 Code to set warning mode moved to Sem_Warn
22112 so that it can be shared by pragma processing.
22114 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22126 * exp_vfpt.adb: Handle /= case
22127 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22239 we are not defining the type.
22240 <E_Record_Type>: Likewise.
22241 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22242 to get advantage of the new maybe_stabilize_reference interface, to
22243 ensure that what we reference is indeed stabilized instead of relying
22244 on assumptions on what the stabilizer does.
22245 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22246 type imported through a limited_with clause, use its non-limited view.
22247 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22249 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22250 of #if sections + explicit comparisons of convention identifiers.

22252 before early-returning for certain types when code generation is
22254 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22255 nullification of gnu_expr we do for objects with address clause and
22256 that we are not defining.
22257 (elaborate_expression_1): Do not create constants when creating
22258 variables needed by the debug info: the dwarf2 writer considers that
22259 CONST_DECLs is used only to represent enumeration constants, and emits
22261 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22262 object with an address clause into an indirect reference, drop the
22263 initializing expression.
22265 (STACK_CHECK_BUILTIN): Delete.
22266 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22275 subtype to build an actual type with bounds template.
22276 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22277 is provided by the front-end, use that subtype to compute the size of
22278 the deallocated object.

22280 check for a potential violation of a No_Elaboration_Code restriction.

22285 maybe_stabilize, for common uses without restriction on lvalues and
22286 without need to check for the success indication.
22287 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22288 pass false instead of 0 as the FORCE argument which is a bool.
22289 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22290 attached to a renaming pointer has been properly stabilized, as no such
22291 object is attached otherwise.
22292 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22293 function uses the "target pointer" return mechanism.
22294 Reinstate conversion of the actual to the type of the formal
22295 parameter before any other specific treatment based on the passing
22296 mechanism. This turns out to be necessary in order for PLACEHOLDER
22297 substitution to work properly when the latter type is unconstrained.

22301 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22303 and to let the caller know if the stabilization has succeeded.
22305 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22306 static output of record constructor if all the components are constant.
22307 (gnat_build_constructor): For a record type, sort the list of field
22308 initializers in increasing bit position order.
22309 Factor common code to build a storage type for an unconstrained object
22310 from a fat or thin pointer type and a constrained object type.
22311 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22312 types variants, and process special cases of VIEW_CONVERT expressions
22313 as their NOP_EXPR counterpart to ensure we get to the
22314 CORRESPONDING_VARs associated with CONST_DECls.
22315 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22316 on the right-hand side.
22318 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22321 are converting back to its original type.
22322 (convert) <JM input>: Fallthrough regular conversion code instead of
22323 extracting the object if converting to a type variant.
22324 (create_var_decl): When a variable has an initializer requiring code
22325 generation and we are at the top level, check for a potential violation
22326 of a No_Elaboration_Code restriction.
22327 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22328 SIZE and SIZE_UNIT which we need for later back-annotations.

22331 is an unchecked union.
22332 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22333 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22334 main variant, just replace the VIEW_CONVERT_EXPR.

22470 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22471 for task component, in the case of a limited aggregate. The enclosed

22513 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22514 'Unrestricted_Access, if the designated type is an interface we
22515 add a type conversion to force the displacement of the pointer
22516 to the secondary dispatch table.
22517 Use Universal_Real instead of Long_Long_Float when we need a high
22518 precision float type for the generated code (prevents gratuitous
22519 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22520 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22521 'Terminated for task interface class-wide objects. Generate a call to
22522 the predefined dispatching routine used to retrieve the _task_id from
22523 a task corresponding record.

22552 the return value into its actual subtype in order to help the backend
22553 to return the actual size instead of the maximum. This is another

22581 2005-11-14 Robert Dewar <dewar@adacore.com>
22583 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22603 attribute of the N_Free_Statement.
22604 Generate itype for classwide designated object in both cases of
22605 user-specified storage pool: specific and class-wide, not only in the
22607 Raise CE when trying to set a not null access type object to null.
22608 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22609 an explicit loop, because freeze nodes make its position variable.

22636 to subprogram, freeze the anonymous subprogram type at the same time,
22637 to prevent later freezing in the wrong scope, such as the enclosing

22884 In addition some minor reorganization of the code has been done to
22885 leave it more clear.
22886 (Analyze_Type_Declaration): If type has previous incomplete tagged
22887 partial view, inherit properly its primitive operations.

22932 Change name Is_Package to Is_Package_Or_Generic_Package
22933 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22939 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22940 not try to rewrite a renamed stream attribute, because the operations
22941 on the type may not have been generated.
22942 Handle properly a renaming_as_body generated for a stream operation
22943 whose default is abstract because the object type itself is abstract.
22944 (Find_Type): If the type is incomplete and appears as the prefix of a
22945 'Class reference, it is tagged, and its list of primitive operations
22946 must be initialized properly.
22947 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22948 private declaration of a parent unit, prior to compiling the private
22949 part of a child unit, find on the scope stack the proper parent entity
22950 on which to link the use clause.

22974 remove address operations.
22975 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22976 statement to inhibit warning.
22977 (Resolve_Unary_Op): Do not produce a warning when
22978 processing an expression of the form -(A mod B)
22979 Use Universal_Real instead of Long_Long_Float when we need a high

22982 (Resolve_Concatenation_Arg): Improve error message when argument is an
22983 ambiguous call to a function that returns an array.
22984 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23959 Hristian Kirtchev <kirtchev@adacore.com>
23960 Javier Miranda <miranda@adacore.com>
23962 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23963 from object notation, the original node is unanalyzed and carries no
23964 semantic information, so that accessiblity checks must be performed on
23965 the type of the actual itself.
23966 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23967 compatibility with Build_Protected_Sub_Specification.
23968 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23974 include the generation of dispatching subprograms when the type
23975 implements at least one interface.
23977 * lib.ads: Extend information in Load_Stack to include whether a given
23978 load comes from a Limited_With_Clause.
23980 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23981 whether a potential circularity is harmless, because it includes units
23982 loaded through a limited_with clause. Extends previous treatment which
23983 did not handle properly arbitrary combinations of limited and
23984 non-limited clauses.
23986 2005-09-01 Nicolas Setton <setton@adacore.com>
23988 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
23989 to be encoded as typ___XBLU_lowerbound__upperbound instead of

23996 (Build_TypeCode_Call): Do not generate dummy null access actual for
23997 calls to the TypeCode TSS.
23999 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24001 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
24002 fully qualified name, to distinguish instances with the same local name.
24004 * g-souinf.ads (Enclosing_Entity): Document that entity name is now

24016 (Close): Deallocate any existing filter for the concerned connection
24018 2005-09-01 Laurent Pautet <pautet@adacore.com>
24020 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24021 position set is provided, we compute one in order to reduce the maximum
24022 length of the keys. This computation first selects a character
24023 position between 1 and the minimum length of the keys in order to
24024 avoid reducing one of the keys to an empty string.
24025 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24026 does not converge. The initialization procedure now comes with a
24027 maximum number of iterations such that when exceeded, an exception is
24028 raised in Compute. The user can initialize this ratio to another value
24030 Reformating and updated headers.
24032 2005-09-01 Javier Miranda <miranda@adacore.com>
24034 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24035 that given an entity T creates and returns an Itype that duplicates the
24036 contents of T. The returned Itype has the null-exclusion
24037 attribute set to True, and its Etype attribute references T
24038 to keep the association between the two entities.
24039 Update copyright notice
24041 * sem_aggr.adb (Check_Can_Never_Be_Null,
24042 Aggregate_Constraint_Checks, Resolve_Aggregate,
24043 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
24045 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

24063 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24064 instead of Set_Subtype_Mark.
24066 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
24067 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
24068 (Result_Definition): New function for N_Function_Specifications.

24072 N_Function_Specification.
24073 (Set_Result_Definition): New procedure for N_Function_Specifications.
24074 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24075 and N_Function_Specification.
24077 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24078 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
24079 Add support for LIMITED NEW for Ada 2005 AI-419
24080 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24081 syntax for anonymous access results.

24097 * lib-writ.adb: Update Copyright notice
24098 (Write_With_Lines): On platforms where file names are case-insensitive,
24099 record the file names in lower case.
24100 (Write_ALI): For D lines, on platforms where file names are
24101 case-insensitive, record the file names in lower case.
24103 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24104 Emmanuel Briot <briot@adacore.com>
24106 * lib-xref.adb (Output_Overridden_Op): Display information on

24133 * snames.h, snames.ads, snames.adb: Introduce entries in
24134 Preset_Names for Name_Disp_Asynchronous_Select,
24135 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24136 Name_Disp_Timed_Select.
24137 New pragma Debug_Policy
24139 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24141 Switch -gnata also sets Debug_Pragmas_Enabled
24143 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24144 handle an explicit -gnata when compiling predefined files.
24146 2005-09-01 Vincent Celier <celier@adacore.com>
24148 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24149 directories of projects that have no Ada sources.
24151 2005-09-01 Robert Dewar <dewar@adacore.com>
24153 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24154 (makes a difference for wide characters)
24156 * widechar.adb, widechar.ads:
24157 Add Wide_Char_Byte_Count feature to count chars vs bytes
24159 2005-09-01 Thomas Quinot <quinot@adacore.com>
24160 Ed Schonberg <schonberg@adacore.com>
24161 Robert Dewar <dewar@adacore.com>
24163 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24164 'Address attribute reference with an overloaded prefix, use the
24165 location of the prefix (not the location of the attribute reference) as
24166 the error location.
24167 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24168 a function renaming thereof, is a valid prefix for 'Size (where it is
24169 intepreted as a function call).
24170 (Statically_Denotes_Entity): New predicate to determine whether the
24171 prefix of an array attribute can be considered static.
24174 (Eval_Attr): Fix failure to evaluate Component_Size for
24175 unconstrained arrays (resulted in wrong value in packed case, since
24176 back end cannot handle this case)
24178 2005-09-01 Robert Dewar <dewar@adacore.com>
24180 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24181 error msgs for most common cases.

24184 2005-09-01 Javier Miranda <miranda@adacore.com>
24185 Ed Schonberg <schonberg@adacore.com>
24187 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24188 become local to the whole package.
24189 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24190 the package was already analyzed the new algorithm "replaces" the
24191 real entities by the shadow ones. This is required to ensure that
24192 the order of these entities in the homonym chains does not change;
24193 otherwise we can have undefined references at linking time because
24194 in case of conflicts the external name of the entities will have
24195 a suffix that depends on the order of the entities in the chain.
24196 (Remove_Limited_With_Clause): Complementary code that completes the
24197 new algorithm and replaces the shadow entities by the real ones.
24198 (Install_Limited_Withed_Unit): When unchaining entities before the
24199 installation of the shadow entities, only regular entities of the
24200 public part must be taken into account. This is required to
24201 keep this routine in synch with the work done by Remove_Limited_
24203 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24204 even if unit is analyzed, because the analysis of the unit is
24205 idempotent in any case, and the limited view of the unit may have to
24206 be installed for proper visibility.
24207 (Expand_Limited_With_Clause): Even if the unit in the implicit
24208 with_clause has been analyzed already, a limited view of the package
24209 must be built for the current context, if it does not exist yet.
24211 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24212 Javier Miranda <miranda@adacore.com>
24213 Gary Dismukes <dismukes@adacore.com>
24215 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24216 defining entity for the instance body, make a new defining identifier
24217 rather than copying the entity of the spec, to prevent accidental
24218 sharing of the entity list.
24219 (Check_Private_View): When exchanging views of private types, build the
24220 list of exchanged views as a stack, to ensure that on exit the exchanges
24221 are undone in the proper order.
24222 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24223 Restore the compilation environment in case of instantiation_error.
24224 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24225 for an anonymous access result.
24226 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24227 (Formal_Entity): Handle properly the case of a formal package that
24228 denotes a generic package renaming.

24232 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24233 clause if the array aggregate is surrounded by parentheses.

24238 Javier Miranda <miranda@adacore.com>
24240 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24242 to check if a type is Constrained in cases related to code generation
24243 (rather than semantic checking) since otherwise we do not generate
24244 similar code for mutable private types depending if their
24245 discriminants are visible or not.
24246 (Check_Abstract_Overriding): Do not complain about failure to override
24247 the primitive operations used in dispatching selects since they will
24248 always be overriden at the freeze point of the type.
24249 (Access_Definition): Separate out handling for resetting the scope
24250 of an anonymous access function result type. Retrieve the scope
24251 of the associated function rather than using Current_Scope, which
24252 does not have a consistent value (depends on whether we're in the
24253 middle of analyzing formal parameters). Add ??? comment about
24254 finding a cleaner way to handle the special cases of scope setting.
24255 (Process_Incomplete_Dependents): A protected operation is never a
24256 dispatching operation (only its wrapper may be).
24257 (Build_Derived_Record_Type): In case of tagged private types that
24258 implement interfaces add derivation of predefined primitive
24260 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24261 by two parameters that are used in case of derivation from abstract
24262 interface types: No_Predefined_Prims is used to avoid the derivation
24263 of predefined primitives from the interface, and Predefined
24264 Prims_Only is used to complete the derivation predefined primitives
24265 in case of private tagged types implementing interfaces.
24266 Fix typo in comments
24267 (Find_Interface_In_Descendant): Protect the frontend against
24268 wrong code with large circularity chains.
24269 (Is_Private_Overriding): Add support for entities overriding interface
24270 subprograms. The test failed because Entities associated with overriden
24271 interface subprograms are always marked as hidden (and used to build
24272 the secondary dispatch table); in this case the overriden entity is
24273 available through the field abstract_interface_alias (cf. override_
24274 dispatching_operation)
24275 (Access_Definition): Set the scope of the type to Current_Scope for the
24276 case of a function with an anonymous access result type.
24277 (Access_Subprogram_Declaration): Handle creation of the type entity for
24278 an access-to-function type with an anonymous access result.
24279 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24280 in handling for N_Access_Function_Definition.
24281 (Analyze_Subtype_Declaration): Modify the text of error message.
24282 (Derived_Type_Declaration): Modify the text of error message.
24283 (Process_Subtype): Modify the text of error message plus cleanup
24284 of one redundant error message.
24285 (Analyze_Component_Declaration): Code cleanup.
24286 (Analyze_Object_Declaration): Code cleanup.
24287 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24288 attribute in case of access types. Code cleanup.
24289 (Array_Type_Declaration): Code cleanup.
24290 (Process_Discriminants): Create the new null-excluding itype
24291 if required. Code cleanup.
24292 (Process_Subtype): Create the new null-excluding itype if
24293 required. Code cleanup.
24294 (Build_Derived_Record_Type): Code cleanup to avoid calling
24295 twice the subprogram derive_subprograms in case of private
24296 types that implement interfaces. In this particular case the
24297 subprogram Complete_Subprograms_Derivation already does the
24298 job associated with the second call.
24300 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24301 conversion to the full view when generating an operation for a
24302 discriminant whose type may currently be private.
24304 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24305 Javier Miranda <miranda@adacore.com>
24307 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24308 V (Obj.F), the rewriting does not involve the indexed component, but
24309 only the selected component itself.
24310 Do not apply the transformation if the analyzed node is an actual of a
24311 call to another subprogram.
24312 (Complete_Object_Operation): Retain the entity of the
24313 dispatching operation in the selector of the rewritten node. The
24314 entity will be used in the expansion of dispatching selects.
24315 (Analyze_One_Call): Improve location of the error message associated
24317 (Analyze_Selected_Component): No need to resolve prefix when it is a
24318 function call, resolution is done when parent node is resolved, as
24320 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24321 when attempting to resolve a call transformed from its object notation.
24322 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24323 of the argument list for each interpretation of the operation.
24324 (Try_Object_Operation): The designated type of an access parameter may
24325 be an incomplete type obtained through a limited_with clause, in which
24326 case the primitive operations of the type are retrieved from its full
24328 (Analyze_Call): If this is an indirect call, and the return type of the
24329 access_to_subprogram is incomplete, use its full view if available.

24332 Gary Dismukes <dismukes@adacore.com>
24334 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24335 access types the null-exclusion and access-to-constant attributes must
24337 (Analyze_Return_Statement): When the result type is an anonymous access
24338 type, apply a conversion of the return expression to the access type
24339 to ensure that appropriate accessibility checks are performed.
24340 (Analyze_Return_Type): For the case of an anonymous access result type,
24341 generate the Itype and set Is_Local_Anonymous_Access on the type.
24342 Add ??? placeholder for check to disallow returning a limited object
24343 in Ada 2005 unless it's an aggregate or a result of a function call.
24344 Change calls from Subtype_Mark to Result_Definition.
24345 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24346 Result_Definition in call to Make_Function_Specification.
24347 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24348 Set_Result_Definition.
24349 (Make_Inequality_Operator): Change formal Subtype_Mark to
24350 Result_Definition in call to Make_Function_Specification.
24351 (Process_Formals): Create the new null-excluding itype if required.
24352 (New_Overloaded_Entity): For an entity overriding an interface primitive
24353 check if the entity also covers other abstract subprograms in the same
24354 scope. This is required to handle the general case, that is, overriding
24355 other interface primitives and overriding abstract subprograms inherited
24356 from some abstract ancestor type.
24357 (New_Overloaded_Entity): For an overriding entity that comes from
24358 source, note the operation that it overrides.
24359 (Check_Conformance, Type_Conformant): Addition of one new formal
24360 to skip controlling formals in the analysis. This is used to
24361 handle overloading of abstract interfaces.
24362 (Base_Types_Match): Add missing case for types imported from
24363 limited-with clauses
24364 (New_Overloaded_Entity): Add barrier to protect the use of
24365 the "alias" attribute.
24367 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24369 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24370 verify that the procedure and the entry are mode conformant.
24371 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24372 as a different operator, which is often a cut-and-paste error.
24374 2005-09-01 Javier Miranda <miranda@adacore.com>
24375 Ed Schonberg <schonberg@adacore.com>
24377 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24378 used in controlling parameters exclude null because it is necessary to
24379 read the tag to dispatch, and null has no tag.
24380 (Override_Dispatching_Operation): If the previous operation is inherited
24381 from an interface, it becomes hidden and does not participate in later
24384 2005-09-01 Javier Miranda <miranda@adacore.com>
24385 Ed Schonberg <schonberg@adacore.com>
24386 Gary Dismukes <dismukes@adacore.com>
24388 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24389 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24390 the expander will generate the corresponding run-time check to evaluate
24392 (Resolve_Call): Check for legal type of procedure name or prefix that
24393 appears as a trigger in a triggering alternative.
24394 (Valid_Conversion): If expression is ambiguous and the context involves
24395 an extension of System, remove System.Address interpretations.
24396 (Resolve_Qualified_Expression): Reject the case of a specific-type
24397 qualification applied to a class-wide argument. Enhance comment
24398 to explain checking of Original_Node.
24399 (Resolve_Type_Conversion): The location of the error message was not
24400 general enough to handle the general case and hence it has been removed.
24401 In addition, this patch improves the text of the message.
24402 (Resolve_Type_Conversion): Add missing support for access to interface
24404 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24405 do not expand if the expression is the actual in a call, because proper
24406 expansion will take place when the call itself is expanded.
24407 (Resolve_Allocator): If the context is an unchecked conversion, the
24408 allocator inherits its storage pool, if any, from the target type of
24411 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24412 Javier Miranda <miranda@adacore.com>
24414 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24415 inherited interface operation that has an implementation, use the
24416 implementation to avoid spurious ambiguities.
24417 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24418 use the Corresponding_Record_Typ attribute to look for the interface
24419 because it is set by the expander (and hence it is not always
24420 available). For this reason we traverse the list of interfaces
24421 (available in the parent of the concurrent type).
24422 (Interface_Present_In_Ancestor): Handle entities from the limited view
24424 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24426 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24427 from the list of required components.
24428 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24429 primitive procedure of a limited interface with a controlling first
24431 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24433 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24434 capture if it is generated in the second operand of a short-circuit
24436 Do not capture values for variables with address clauses.
24437 (Is_Object_Reference): Treat a function call as an object reference only
24438 if its type is not Standard_Void_Type.
24440 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24442 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24443 to a variable that is statically known to be constant.

24460 Document new treatment of wide characters in max line length
24462 Remove -gnatL/-gnatZ switches, no longer used.
24463 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

25223 Arnaud Charlet <charlet@adacore.com>
25225 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25226 longer protected objects. They have been replaced by lower-level
25227 suspension objects made up by a mutex and a condition variable (or
25228 their equivalent given a particular OS) plus some internal data to
25229 reflect the state of the suspension object.
25230 (Initialize, Finalize): Add this initialization procedure for
25231 Suspension_Object, which is a controlled type.
25232 (Finalize): Add the finalization procedure for Suspension_Object,
25233 which is a controlled type.
25235 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25236 Ada.Synchronous_Task_Control because there is no longer a need for a
25237 VxWorks specific version of this package. Target dependencies
25238 has been moved to System.Task_Primitives.Operations.
25240 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25242 (InitializeCriticalSection, EnterCriticalSection,
25243 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25244 pCriticalSection by an anonymous access type so that we avoid problems
25245 of accessibility to local objects.

25251 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25252 set the environment task mask here.
25253 (Current_State): Add this function that returns the state of the
25255 (Set_False): Add this procedure that sets the state of the suspension
25257 (Set_True): Add this procedure that sets the state of the suspension
25258 object to True, releasing the task that was suspended, if any.
25259 (Suspend_Until_True): Add this procedure that blocks the calling task
25260 until the state of the object is True. Program_Error is raised if
25261 another task is already waiting on that suspension object.
25262 (Initialize): Add this procedure for initializing the suspension
25263 object. It initializes the mutex and the condition variable which are
25264 used for synchronization and queuing, and it sets the internal state
25266 (Finalize): Add this procedure for finalizing the suspension object,
25267 destroying the mutex and the condition variable.

25272 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25273 which provides a low-level abstraction (using operating system
25274 primitives) for Ada.Synchronous_Task_Control.
25275 This object is made up by a mutex (for ensuring mutual exclusion), a
25276 condition variable (for queuing threads until the condition is
25277 signaled), a Boolean (State) indicating whether the object is open,
25278 and a Boolean (Waiting) reflecting whether there is a task already
25279 suspended on this object.

25693 instantiations of Unchecked_Conversion, and allows them in bodies that
25694 are to be inlined by the front-end. When the body comes from an

25721 way as a normal component of an anonymous access type.
25722 (Resolve_Allocator): When an allocator's designated type is a class-wide
25723 type, check that the accessibility level of type given in the

25744 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25745 check on possible violation of restriction No_Direct_Boolean_Operators

26752 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26755 error messages if expansion has been disabled due to previous
26756 (unrelated) errors).
26758 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26759 is disabled, the entity denoted by the argument is the access type
26760 itself, not an underlying record type, so there is no need to go back
26761 to the Corresponding_Remote_Type.

26771 denotes a type in the class.
26772 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26773 of Name_Generic_Dispatching_Constructor.
26775 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26776 05 unit for AI-260-02).

26790 the case of renaming of stream attributes when the renaming denotes a
26791 generic formal subprogram association for an abstract formal subprogram.
26792 Check that the attribute is a primitive stream attribute (and not
26793 a class-wide stream attribute) and then rewrite the attribute name
26794 as the name of the appropriate compiler-generated stream primitive.

26798 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26806 itype whose parent is controlled and not yet frozen, do not create a
26807 freeze node for the itype if expansion is disabled.
26809 2005-03-29 Vincent Celier <celier@adacore.com>
26811 * make.adb (Gnatmake): Don't fail if the main project file is declared
26812 as having no Ada sources. Do not display message "no sources to
26813 compile" in quiet output.
26815 2005-03-29 Doug Rupp <rupp@adacore.com>
26817 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26833 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26834 rather than proceed ahead using a junk attribute name.
26836 2005-03-29 Vincent Celier <celier@adacore.com>
26838 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26840 * prj-part.adb (Parse_Single_Project): Set the location of a project
26841 on its defining identifier, rather than on the reserved word "project".
26843 * prj-proc.adb (Expression): Adapt to the fact that default of external
26844 references may be string expressions, not always literal strings.
26845 (Recursive_Process): Set Display_Name equal to Name
26846 when Location is No_Location, that is when there is no actual file.
26847 Get the Display_Name of the project from the source, when it is not a
26849 (Process): Use the Display_Name in error messages
26851 * prj-strt.adb (External_Reference): Allow default to be string

27514 Update documentation on Must_Be_Byte_Aligned for new spec
27516 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27517 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27518 uses of the Access_Disp_Table attribute to reference the first dispatch
27519 table associated with a tagged type. As
27520 part of the implementation of abstract interface types,
27521 Access_Disp_Table has been redefined to contain a list of dispatch
27522 tables (rather than a single dispatch table).
27523 Similarly, upgrade all the references to Tag_Component by the
27524 new attribute First_Tag_Component.
27525 (Find_Inherited_TSS): Moved to exp_tss.
27526 Clean up test in Expand_N_Object_Declaration for cases
27527 where we need to do a separate assignment of the initial value.

27529 declaration of a tagged type is an aggregate, no need to generate an
27530 additional tag assignment.
27531 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27533 Bit packed array ops are only called if operands are known to be
27535 (Component_Equality): When returning an N_Raise_Program_Error statement,
27536 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27537 expects that only expressions have a bona fide type).
27538 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27539 determine the amount of data to be copied.
27541 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27542 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27569 (Task_Body_Procedure): Removed.
27570 (Set_Task_Body_Procedure): Removed.
27571 These subprogram have been removed because the attribute
27572 Task_Body_Procedure has been moved to the corresponding task type
27573 or task subtype entity to leave a field free to store the list
27574 of interfaces implemented by a task (for AI-345)
27575 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27576 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27577 expression flag Do_Range_Check
27578 (Exception_Junk): Change to Flag7 to accomodate above change
27579 (Box_Present, Default_Name, Specification, Set_Box_Present,
27580 Set_Default_Name, Set_Specification): Expand the expression
27581 "X in N_Formal_Subprogram_Declaration" into the corresponding
27582 two comparisons. Required to use the csinfo tool.

27585 "with string" given.
27587 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27590 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27593 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27594 attribute Task_Body_Procedure rather than the old semantic field that
27595 was available in the task_type_declaration node.
27597 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27598 interface type definitions.
27599 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27602 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27603 task type declaration.

27605 protected type declaration.
27607 2005-03-15 Doug Rupp <rupp@adacore.com>
27608 Vincent Celier <celier@adacore.com>
27610 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27611 (Gen_Output_File_C): Likewise.
27612 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning
27614 2005-03-15 Thomas Quinot <quinot@adacore.com>
27616 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27617 is an N_Raise_Constraint_Error node, create a new copy of it without
27618 going through a call to Duplicate_Subexpr.

27623 Ed Schonberg <schonberg@adacore.com>
27629 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27630 representation clause that prescribes a size not equal to the rounded
27631 size of their types.
27632 (gnat_to_gnu_entity, case E_Component): Always look at
27633 Original_Record_Component if Present and not the entity.
27634 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27635 of tagged extension types by not making field for components that are
27637 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27638 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27639 expression to the type of the object when the object is constant.
27640 Reverse defer_debug_incomplete_list before traversing it, so that trees
27641 are processed in the order at which they were added to the list. This
27642 order is important when using the stabs debug format.
27643 If we are deferring the output of debug information, also defer this
27644 output for a function return type.
27645 When adding fields to a record, prevent emitting debug information
27646 for incomplete records, emit the information only when the record is
27648 (components_to_record): New parameter defer_debug.
27649 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27650 (gnat_to_gnu_field_decl): New function.

27652 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27653 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27654 No longer update discriminants to not be a COMPONENT_REF.
27655 (copy_alias_set): Strip padding from input type; also handle
27656 unconstrained arrays properly.
27658 * gigi.h (write_record_type_debug_info): New function.
27659 Convert to use ANSI-style prototypes. Remove unused
27660 declarations for emit_stack_check, elab_all_gnat and

27662 (gnat_to_gnu_field_decl): New decl.
27664 * utils.c (write_record_type_debug_info): New function.

27669 (convert) <UNION_TYPE>: Accept slight type variations when
27670 converting to an unchecked union type.
27672 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27673 replace the N_Freeze_Entity with a null statement.
27675 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27676 within a constrained subcomponent of an enclosing record, place the
27677 freeze nodes in the scope stack entry for the enclosing record.

27679 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27680 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27681 within records; allow them to have freeze nodes if their base types
27684 * exp_util.adb (Remove_Side_Effects): Properly test for
27685 Expansion_Delayed and handle case when it's inside an
27686 N_Qualified_Expression.
27688 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27689 Comes_From_Generic, to recognize accurately that the parent type in a
27690 derived type declaration can be traced back to a formal type, because
27691 it is one or is derived from one, or because its completion is derived
27693 (Constrain_Component_Type): If component comes from source and has no
27694 explicit constraint, no need to constrain in in a subtype of the
27696 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27697 Minor change to propagate Is_Ada_2005 flag
27699 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27700 Expansion_Delayed is False.
27701 (assoc_to_constructor): Ignore fields that have a
27702 Corresponding_Discriminant.
27703 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27704 function returns "by target", dereference the target pointer using the
27705 type of the actual return value.
27706 <all>: Be prepared for a null gnu_result.
27707 (processed_inline_subprograms): Check flag_really_no_inline

27718 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27719 Must_Be_Byte_Aligned for cases where we do not need to use a
27720 System.Pack_nn unit.
27722 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27724 Needed now that we do some processing for IN parameters as well. This
27725 may well fix some unrelated errors.
27726 (Expand_Call): Handle case of unaligned objects (in particular those
27727 that come from packed arrays).
27728 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27729 renamed entity is an inherited operation, re-expand the call using the
27730 original operation, which is the one to call.
27731 Detect attempt to inline parameterless recursive subprogram.
27732 (Represented_As_Scalar): Fix to work properly with private types
27733 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27734 accurate estimate. Yields True in far fewer cases than before,
27735 improving the quality of code that depends on this test.
27737 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27738 over both visible and private declarations to remove them from tree,
27739 and mark subprograms declared in package as eliminated, to prevent
27740 spurious use in subsequent compilation of generic units in the context.
27742 * exp_util.ads: Minor cleanup in variable names
27744 * sem_eval.ads, sem_eval.adb: Minor reformatting
27745 (Compile_Time_Known_Bounds): New function

27749 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27750 determining whether an unchecked conversion is needed for the argument
27751 of an initialization call.
27753 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27755 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27756 that appears in the instantiation rather than the internal subtype
27757 generated in the wrapper package, to avoid anomalies in gigi when the
27758 target is derived from a private type whose full view is an access type.
27760 2005-03-15 Robert Dewar <dewar@adacore.com>
27762 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27764 Add documentation to replace the use of this flag
27765 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27768 2005-03-15 Thomas Quinot <quinot@adacore.com>
27770 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27771 here from exp_attr so it can be shared between exp_attr and exp_dist.
27772 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27773 all TSS names, not a subset thereof, and the previous name introduced
27774 an unnecessarily confusion that a distinction might exist between
27775 "OK" TSS names and some "not OK" TSS names.
27777 2005-03-15 Doug Rupp <rupp@adacore.com>
27779 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27782 2005-03-15 Pascal Obry <obry@adacore.com>
27783 Eric Botcazou <ebotcazou@adacore.com>
27787 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27788 when IN_RTS. This is to work around a bootstrap path problem.
27790 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27791 table and pass it to __gnat_install_SEH_handler().
27792 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27794 * lang.opt: Fix specification of -fRTS=.
27796 2005-03-15 Doug Rupp <rupp@adacore.com>

27798 Vincent Celier <celier@adacore.com>
27799 Arnaud Charlet <charlet@adacore.com>
27802 This change works fine when gnatlib is built from the gcc directory,
27803 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27804 is not passed to ada/Makefile.in, so more work is needed by a
27805 Makefile/configure expert.
27807 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27808 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27809 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27811 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.

27816 2005-03-15 Robert Dewar <dewar@adacore.com>
27818 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27820 * impunit.adb: Add GNAT.UTF_32
27822 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27824 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27825 now uses GNAT.UTF_32).
27827 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27828 capabilities for categorizing characters using Unicode categories
27830 2005-03-15 Ed Schonberg <schonberg@adacore.com>

27839 Ed Schonberg <schonberg@adacore.com>
27841 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27842 parameter reported some error we immediately return. This improves the
27843 behaviour of the frontend in case of errors.
27844 (Install_Parent, Remove_Parent): Introduce new flag
27845 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27846 ancestor of a generic child unit, when the child is being instantiated.
27847 (Inline_Instance_Body): If we are compiling the private
27848 part or the body of a child unit, restore the proper visibility of the
27849 parents after compiling the instance body.

27852 Javier Miranda <miranda@adacore.com>
27855 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27856 of a private type, in which case it is underlying_type that denotes
27857 the proper task. Also modified to use the new entity attribute
27858 that is directly available in the task type and task subtype entities
27859 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27860 arrays when other dimensions than the first are constrained by
27861 discriminants of an enclosing record.
27862 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27863 a combination of indexed and selected components, find ultimate entity
27864 and generate the appropriate reference for it, to suppress spurious
27866 (Note_Possible_Modification): If an entity name has no entity, return.
27867 (Is_Variable): A function call never denotes a variable.
27868 (Requires_Transient_Scope): For record types, recurse only on

27874 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27875 Eliminated as candidates for resolution. Both efficient, and avoids
27876 anomalies with operators declared in deleted code.
27877 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27878 expansion is disabled (as when compiling a generic) to prevent spurious
27879 warnings on prefixes of selected components.
27881 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27883 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27884 attached to a list before checking whether it appears in the private
27885 declarations of the current package.
27886 (Make_Inequality_Operator): Insert declaration in proper declarative
27887 list rather than just setting the Parent field, so that
27888 Is_Private_Declaration can handle it properly.
27890 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27892 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27893 a renaming a body, check that the renamed subprogram in not intrinsic.
27894 (Find_Direct_Name): If several use_visible entities hide
27895 each other, and the context is a predefined file compiled through
27896 rtsfind, keep only the entity that comes from a predefined file.
27898 2005-03-15 Geert Bosch <bosch@adacore.com>
27900 * s-fatgen.adb (Valid): Extend special exceptions to account for long

28295 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28296 Remove ["0A"] from comment, since it can look like a line terminator.
28297 Currently we don't permit this, but this is under discussion by the
28298 ARG, and it is easy enough to use a different example.
28300 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28301 handling UTF-32 encoding for wide wide character.
28302 Implement new brackets coding ["hhhhhhhh"]

28308 bit range Add full UTF-32 support.
28309 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28310 notify that constraint error will be raised at run-time
28311 because a null value is assigned to a null-excluding object.
28312 Remove some obsolete declarations and make Char_Code
28315 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28316 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28317 Rcheck subprograms.
28319 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28320 wrong null-exclusion value by a warning message.
28321 (Enable_Range_Check): Do range check if the prefix is an
28322 explicit dereference whose designated object is an unconstrained array.
28323 Current algorithm for removing duplicate checks is over-eager in this

28327 null-exclusion value by a warning message
28329 * atree.h, atree.ads, atree.adb: Remove Char_Code field support

28335 * exp_util.adb (Insert_Actions): Replace
28336 N_Formal_Subprogram_Declaration by
28337 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
28338 Char_Literal_Value field is now a Uint.
28340 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28341 defined for subprogram renaming declarations. When set, the field
28342 indicates the defining entity of a corresponding formal subprogram
28343 when the renaming corresponds to a formal subprogram association in an
28345 (Set_Corresponding_Formal_Spec): New procedure to return
28346 Corresponding_Formal_Spec field.
28347 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28348 (which is now a subtype).
28349 Char_Literal_Value field is now a Uint
28351 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28352 pointer to the base of the dispatch table.
28353 Minor changes to comments.
28354 (Controlling_Type): New function for determining the tagged type
28355 associated with a tagged primitive subprogram.
28356 (Expand_Dispatching_Call): Add support for a controlling actual that is
28357 directly a value of type Ada.Tag rather than a tagged object.
28359 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28360 describing the new layout.
28361 (Dispatch_Table): The expander computes the actual array size, allocates
28362 the Dispatch_Table record accordingly, and generates code that displaces
28363 the base of the record after the Typeinfo_Ptr component. The access to
28364 these components is done by means of local functions.
28365 (Offset_To_Top): New function.
28366 (Typeinfo_Ptr): New function.
28367 (Get_TSD): Modified to access the new position of the TSD.
28368 (Set_TSD): Modified to save the TSD in its new position.
28370 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28371 case of formal abstract subprograms. Add check and message for -gnat05.
28374 * sem_ch12.adb: Add with and use for Sem_Disp.

28378 N_Formal_Subtype_Declaration (which is now a subtype).
28379 (Analyze_Formal_Subprogram): Add handling for
28380 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28381 dispatching, setting the controlling status of the formal parameters
28382 and result, and issuing an error if there is no controlling type for
28383 the formal subprogram.
28384 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28385 which is an unclean use of that field, we set the new field
28386 Corresponding_Formal_Spec to make the formal subprogram available to
28387 processing in Analyze_Subprogram_Declaration.
28388 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28389 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28390 Constrained, so that it is is does not statically match its anonymous
28393 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28394 abstract formal subprograms in error check for functions returning
28395 abstract types. Set scope of new designator for
28396 a parameterless subprogram, so that it is available when checking the
28397 body for nested subprograms, before full analysis of said body.
28398 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28399 subprogram only if inner one comes from source.
28400 (Analyze_Function_Call): If the call is given in object notation, the
28401 analysis of the name rewrites the node and analyzes it with the proper
28402 argument list. After analyzing the name, if the call has been rewritten
28403 and the result type is set, no further analysis is needed.
28404 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28405 mark in function specification, in a context where the formals are
28406 visible and hide outer homographs.
28408 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28409 as the tagged type for the cases of abstract formal subprograms and
28410 renamings of those. Clean up spec comments.
28411 (Check_Dispatching_Context): Add error message to indicate "abstract
28412 procedure", covering the case of a call to a formal abstract procedure
28413 that has statically tagged operands.
28414 (Check_Dispatching_Call): Check for the case of an actual given by
28415 a tag-indeterminate function call whose type is an ancestor of the
28416 containing call's associated tagged type. This situation can occur
28417 for inherited primitives with function defaults. In this case we
28418 use the tagged type's tag directly as the controlling argument for
28420 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28422 * sprint.adb (Sprint_Node_Actual): Split
28423 N_Formal_Subprogram_Declaration into two alternatives for the new
28424 cases N_Formal_Abstract_Subprogram_Declaration and

28495 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28499 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28500 on the field if Pragma Component_Alignment (Storage_Unit).
28501 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28502 side-effects as if it were a constant; also make SAVE_EXPR to protect
28504 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28506 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28507 (components_to_record): Test it.

28520 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28522 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28523 component of an array of arrays in an assignment context, and the
28524 aggregate has component associations that require sliding on
28525 assignment, force reanalysis of the aggregate to generate a temporary
28526 before the assignment.
28527 (Must_Slide): Make global to the package, for use in Gen_Assign.
28529 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28531 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28532 unchecked union with no inferable discriminants, return a
28533 Raise_Program_Error node, rather than inserting it at the point the
28535 (Expand_Record_Equality, Component_Equality): Handle properly the case
28536 where some subcomponent is an unchecked union whose generated equality
28537 code raises program error.
28539 2005-02-09 Doug Rupp <rupp@adacore.com>
28541 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28545 Arnaud Charlet <charlet@adacore.com>
28547 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28548 address of the exception registration. The Win32 version of this
28549 routine calls __gnat_install_SEH_handler() to initialize the SEH
28550 (Structured Exception Handling) handler.
28551 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28552 SEH (Structured Exception Handling) now.
28553 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28554 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28555 preprocessor condition protecting the call to the extra eh setup
28556 subprogram, which is only available for the ppc target.
28557 (__gnat_clear_exception_count): replaced reference to
28558 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28560 * seh_init.c: New file.
28562 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28563 (GNATBIND_OBJS): Idem.
28565 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28566 routine takes a new parameter (a pointer to the exception registration
28567 for the SEH (Structured Exception Handling) support.
28569 * raise.h: (__gnat_install_SEH_handler): New prototype.
28570 Update copyright notice.
28572 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28573 record and initialize it by calling __gnat_install_SEH_handler.

28583 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28584 [VMS]: Add translations for g-enblsp.adb.
28586 * s-asthan-vms.adb: Removed.
28587 * s-asthan-vms-alpha.adb: Added.
28589 2005-02-09 Pascal Obry <obry@adacore.com>
28591 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.

28598 -shared-libgcc is now used by default on some systems (e.g. linux with
28600 Remove references to Makefile.prolog/generic, no longer used.
28602 2005-02-09 Vincent Celier <celier@adacore.com>
28604 * prj-makr.adb (Process_Directory): Put file name in canonical case
28605 before matching against the patterns.
28606 If gnatname has been invoked as <prefix>-gnatname
28607 then invoke the compiler as <prefix>-gcc, not just "gcc".
28609 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28611 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28612 with expansion disabled. The actual subtype is needed among other
28613 places when the selected component appears in the context of a loop
28614 bound, and denotes a packed array.
28615 (Operator_Check): Always use the first subtype in the
28616 error message, to avoid the appearance of internal base types.
28617 (Transform_Object_Operation): Copy each actual in full
28618 to the parameter associations of the constructed call, rather than
28619 using the shallow copy mechanism of New_Copy_List. This ensures that
28620 the chaining of named associations is done properly.
28621 (Complete_Object_Operation): Rewrite node, rather than
28622 replacing it, so that we can trace back to the original selected
28625 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28626 and calls that use object notation, if the called function is not
28627 declared in a withed unit, place the elaboration constraint on the
28628 unit in the context that makes the function accessible.
28629 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28630 imposes an elaboration constraint between two packages.
28632 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28634 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28635 views of a private type after handling its private dependents, to
28636 maintain proper stack discipline between entry and exit from the
28639 2005-02-09 Cyrille Comar <comar@adacore.com>

28652 recursion warnings when compiled with -gnatdm.
28654 2005-02-09 Robert Dewar <dewar@adacore.com>
28656 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28657 Slight fix to documentation of -gnaty with no parameters
28659 * xr_tabls.ads: Add ??? comment for missing overall comment
28661 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28662 we now use by default.
28664 * xsnames.adb: Adjust end of file test to look for five space followed
28665 by '#' instead of six spaces. The format of xsnames.adb was modified
28666 in the last update.
28668 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28671 * clean.adb: Minor reformatting.
28673 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28674 gnatname.adb: Minor reformatting
28675 Add 2005 to copyright output when utility is run
28677 * csets.adb: Eliminate obsolete comment
28679 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28682 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28684 2005-02-09 Sergey Rybin <rybin@adacore.com>
28686 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28687 the difference between compact and incompact layout and add the record
28688 representation clause to the example illustrating different layouts.
28689 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28690 component clauses").
28692 2005-02-09 Florian Villoing <villoing@adacore.com>
28694 * gnat_ugn.texi: Fix typos.
28695 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28697 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28698 in the generated documentation.
28700 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28702 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28733 from the VxWorks kernel) that is needed for getting the active
28734 priority of the different tasks.
28736 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28737 Use a pragma Elaborate_Body in the spec file instead.
28738 Noticed by code reading.
28740 2005-02-09 Thomas Quinot <quinot@adacore.com>
28742 * exp_util.ads: Minor correction in comment.
28744 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28746 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28747 since this procedure is now too complex to be worth inlining.

29167 note that it applies to obsolete GNAT features, which was previously
29168 omitted. Second we contrast the behavior with that of the new
29169 Ada 2005 AI-368 restriction No_Obsolescent_Features.

29402 "no bitfield creation", to be used by make_aligning_type. Don't
29403 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29404 fields claimed addressable still have to be bitfields. Use
29405 value_factor_p instead of a raw binop construction to check for the
29406 position's alignment.

29413 Ed Schonberg <schonberg@adacore.com>
29415 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29416 with an implicit dereference as its prefix, use
29417 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29419 prefix is generated, if appropriate.
29421 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29422 dereference is rewritten to an explicit one, generate a reference to
29423 the entity denoted by its prefix using the original prefix node, so

29425 access value, if appropriate.
29427 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29428 emitting 'assigned but never read' warning on a variable on the basis

29442 an external name, to be handled by the back end.
29444 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29445 subprogram which is Imported with convention Intrinsic if an
29446 External_Name argument is specified.
29447 (Process_Import_Or_Interface): Properly diagnose link name argument.
29448 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29473 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29474 PCS-specific part of Add_Stub_Type.

29501 (Generate_Reference): Handle properly a reference to an entry formal,
29502 when an accept statement has a pragma Unreferenced for it.
29504 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29505 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29506 the body, to ensure that warnings are properly emitted for each accept
29507 statement of a given task entry.

29529 (Remove_Next_Debug): Same fix
29531 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

29535 (Remove_Next): Same cleanup
29537 2004-12-07 Thomas Quinot <quinot@adacore.com>
29539 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29540 used to record an implicit dereference as a read operation on its
29541 prefix when operating under -gnatc. Necessary to avoid spurious
29542 'variable assigned but never read' warnings in that mode.
29543 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29544 is a non-overloaded implicit dereference, call the above subprogram to
29545 ensure proper recording of references.
29547 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29549 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29597 2004-12-07 Vincent Celier <celier@adacore.com>
29599 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29600 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29601 and -eit to -ept. Added qualifier
29602 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29604 2004-11-27 Andreas Schwab <schwab@suse.de>
29606 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29608 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29610 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29611 internal implementation unit GNAT.Sockets.Thin,
29612 as their usage for sockets is non-portable (using the read and write
29613 functions from the system runtime library is fine on UNIX but won't
29614 work under Windows).
29616 * mingw32.h: Update copyright notice.
29618 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29670 new Others_Value and All_Others_Value objects.
29671 (struct attrib): Rename "arg" component as "args", since GCC expects a
29672 list of arguments in there.
29674 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29675 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29678 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29679 others_decl and all_others_decl instead of hardcoded dummy addresses
29680 to represent "others" and "all others" choices, which is cleaner and
29681 more flexible with respect to the possible eh pointer encoding policies.
29683 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29684 (process_attributes): Account for the naming change of the "args"
29685 attribute list entry component.
29687 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29688 cumulating attributes for different entities into a single list.
29689 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29690 attributes for the current entity and propagate first subtype
29691 attributes to other subtypes.
29692 <E_Procedure>: Attribute arguments are attr->args and not
29693 attr->arg any more.
29694 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29695 argument provided, as this is what GCC expects. Use NULL_TREE instead
29698 2004-11-18 Robert Dewar <dewar@adacore.com>
29700 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29733 (First_RCI_Subprogram_Id): Document this constant.
29734 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29736 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29737 replaced with calls to Get_Library_Unit_Name_String. Previously there
29738 were several instances of the same code in different locations in the
29739 compiler; this checkin completes the replacement of all of these
29740 instances with calls to a common subprogram.
29741 Minor reformatting.

29774 that the pragmas are properly attached to the tree, and that no
29775 nodes are improperly shared.
29777 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29778 pragmas to Exp_Prag, which is more appropriate.
29779 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29780 check for duplicates Remove use of Is_Psected flag, no longer needed.
29781 Use new Make_String_Literal function with string.
29783 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29784 that are functions return universal values, that have to be converted
29785 to the context type.
29786 Use new Make_String_Literal function with string.
29787 (Get_Stream_Convert_Pragma): New function, replaces the use of
29788 Get_Rep_Pragma, which had to be kludged to work in this case.
29790 * freeze.adb: Use new Has_Rep_Pragma function
29792 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29793 function with string.
29794 Use new Has_Rep_Pragma function.
29796 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29799 2004-11-18 Robert Dewar <dewar@adacore.com>
29801 * errout.ads, errout.adb: (First_Sloc): New function
29803 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29804 check (-gnatyx) instead of being included as a redundant construct
29807 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29808 Style_Check_Order_Subprograms.
29810 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29811 stylesw.adb: Add Style_Check_Xtra_Parens
29813 * usage.adb: Add line for -gnatyx (check extra parens)
29815 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29817 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29818 Robert Dewar <dewar@adacore.com>
29820 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29821 discriminant of a constrained subtype, analyze the copy of the
29822 corresponding constraint, because in some cases it may be only
29823 partially analyzed.
29824 Removes long-lived ??? comments.
29826 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29827 handled controlled or secondary-stack expressions within the
29828 iteration_scheme of a loop.
29830 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29831 bounds that may contain functions calls, to prevent memory leaks when
29832 the bound contains a call to a function that uses the secondary stack.
29833 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29834 generate temporaries for loop bounds that might contain function calls
29835 that require secondary stack and/or finalization actions.
29837 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29838 selected component and the selector is overloadable (not just a
29839 function) treat as function call, Analyze_Call will disambiguate if
29841 (Analyze_Selected_Component): Do not generate an actual subtype for the
29842 selected component if expansion is disabled. The actual subtype is only
29843 needed for constraint checks.
29844 (Analyze_Allocator): If restriction No_Streams is set, then do
29845 not permit objects to be declared of a stream type, or of a
29846 composite type containing a stream.
29848 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29849 No_Streams no longer prohibits with'ing this package.
29851 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29852 discriminants, but the parent base has unknown discriminants, there is
29853 no discriminant constraint to inherit. Such a discrepancy can arise
29854 when the actual for a formal type with unknown discriminants is a
29855 similar private type whose full view has discriminants.
29856 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29857 do not permit objects to be declared of a stream type, or of a
29858 composite type containing a stream.
29860 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29862 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29863 protected operations.
29865 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29866 generated name, it complicates decoding in gdb and hinders debugging
29867 of protected operations.
29868 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29869 flag for the protected entry barrier function.
29870 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29871 flag for the protected entry function.
29873 2004-11-18 Nicolas Setton <setton@adacore.com>
29875 * expect.c: Define __unix__ when __APPLE__ is defined.
29877 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29878 Darwin-specific section.
29880 * lang-specs.h: Change the placement of the %1 marker.
29881 Works around the fact that gcc adds -fPIC by default under Darwin.
29883 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29885 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29886 type of the object with the packed array type, set the Analyzed flag
29887 on the object if it is an entity or simple indexed component, to avoid
29888 spurious type errors.
29890 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29892 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29893 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29894 separate line from the version message.
29896 2004-11-18 Ed Falis <falis@adacore.com>
29898 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29900 (init_float): Eliminate initialization of floating point status for
29901 AE653. The instructions have no effect for vThreads.
29903 2004-11-18 Vincent Celier <celier@adacore.com>
29905 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29906 gnatbind is invoked with -shared.
29908 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29910 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29911 for Detect_Blocking which is redundant with the check done within the
29912 procedure Protected_Single_Entry_Call.
29913 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29914 Detect_Blocking which is redundant with the check done within the
29915 procedure Protected_Single_Entry_Call.
29917 2004-11-18 Vincent Celier <celier@adacore.com>
29919 * makegpr.adb (Compile): Put the compiling switches (in package
29920 Compiler and on the command line) immediately after "-c", instead of
29921 at the end of the command line invocation of the compiler, when
29922 compiling a non-Ada file.
29923 (Build_Global_Archive): When there is no need to rebuild the archive,
29924 set Global_Archive_Exists, so that the archive is passed to the linker
29927 2004-11-18 Robert Dewar <dewar@adacore.com>
29928 Sergey Rybin <rybin@adacore.com>
29931 Remove extra paren check from list of checks for redundant constructs
29932 Add documentation of new -gnatyx style check (check extra parens)
29933 Remove paragraph about gnatelim debug options.
29935 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29936 objects rather than forbidding dependencies on the package Ada.Streams.
29938 * sinfo.ads: Add ??? note that we should document pragmas passed to
29941 * g-expect.ads: Fix a few typos in the comments.
29943 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29945 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29948 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29950 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29952 2004-11-07 Andreas Schwab <schwab@suse.de>
29954 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29956 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29959 * Makefile.in (darwin): Set soext to .dylib.
29961 2004-10-26 Vincent Celier <celier@gnat.com>
29962 Thomas Quinot <quinot@act-europe.fr>
29964 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29965 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29966 there is no use of GNAT.Sockets.Constants.
29967 Remove remaining pragma Import for C_Write
29968 Remove C_Read and C_Write from internal implementation unit
29969 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29970 the read and write functions from the system runtime library is fine
29971 on UNIX but won't work under Windows).
29973 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29974 (Check_Selector): Use C_Recv instead of C_Read.
29975 Selectors are the GNAT.Sockets abstraction to perform a select()
29976 call on a set of descriptors. To allow abortion of an ongoing
29977 select operation, some data is written to a dedicated socket that
29978 is always monitored.
29979 Under Windows, the write and read library functions cannot operate
29980 on sockets, so we need to use send and recv instead, which is portable
29981 across all supported platforms.
29983 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29984 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29985 (using the read and write functions from the system runtime library is
29986 fine on UNIX but won't work under Windows).
29988 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29990 * mlib-tgt-darwin.adb: New file.
29992 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29993 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29994 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29995 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29998 * Makefile.in: Add support for building shared libraries under Darwin.
29999 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30000 the low level EH init subprogram to be called from __gnat_initialize.
30002 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30003 indicates which options to pass to the archive indexer.
30005 * mlib-utl.adb: Add support for calling ranlib with additional
30006 options. This is needed for instance under Mac OS X.
30007 (Ranlib_Options): New global variable, used to store the potential
30008 options to pass to ranlib.
30009 (Ar): Use Ranlib_Options when spawning ranlib.
30010 (Initialize): Set the value of ranlib option.
30012 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30014 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30015 instead of 8K, to reflect the real potential needs for stack-checking
30018 2004-10-26 Pascal Obry <obry@gnat.com>
30020 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30022 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30023 Windows only the initial thread stack size can be set so it is good to
30024 start we a low stack size.
30025 The OS will adjust the size as needed.
30027 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30028 Nicolas Setton <setton@act-europe.fr>
30030 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30031 "__unix__" instead of "unix".
30032 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30033 sections were just mistakenly ignored. The former is
30034 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30035 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30036 of hpux. This prevents an unwanted definition of the symbol
30037 convert_addresses in adaint.o.
30039 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30041 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30042 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30044 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30046 * a-filico.ads, a-filico.adb: fix incorrect header.
30048 2004-10-26 Javier Miranda <miranda@gnat.com>
30050 * a-ststio.ads: Fix typo in identifier
30052 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30054 * sem_ch4.adb: Minor reformatting.
30056 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30058 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30059 enabled, check the result of unary and binary operations when the
30060 expression is the right-hand side of an assignment.
30062 2004-10-26 Vincent Celier <celier@gnat.com>
30064 * clean.adb (Delete): Do not output warnings when in quiet output and
30065 not in verbose mode.
30066 (Force_Deletions): New Boolean flag, defaulted to False
30067 (Delete): Only delete a file if it is writable, and when
30068 Force_Deletions is True.
30069 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30070 (Usage): Line for new switch -f
30071 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30074 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30076 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30077 JM type only if its size matches that of the wrapper. When a size is
30078 prescribed and the field is not aliased, remove the wrapper of a JM
30079 type only if the size is not greater than that of the packed array.
30080 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30083 2004-10-26 Geert Bosch <bosch@gnat.com>
30085 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30086 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30087 (Pred): Implement in terms of Succ.
30089 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30091 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30092 unchecked conversion is safe for in-place use if the expression of the
30093 conversion is safe.
30094 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30095 be expandable in place even if the aggregate does not come from source.
30096 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30097 designated object of an allocator in place, rather than building it
30098 first on the stack. The previous scheme forces a full copy of the array,
30099 and may be altogether unsusable if the size of the array is too large
30100 for stack allocation.
30102 2004-10-26 Robert Dewar <dewar@gnat.com>
30104 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30105 compares if the component is atomic.
30107 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30108 array assignment if the component type is atomic.
30110 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30111 Eric Botcazou <ebotcazou@act-europe.fr>
30113 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30114 is aliased and is a by_reference type, do not pass by copy.
30115 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30116 detect whether the call is in the right side of an assignment or
30117 the expression of an object declaration. Recurse on component
30118 association within aggregates.
30119 Call it in the condition that determines whether the temporary is
30120 necessary for correct stack-checking.
30122 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30124 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30125 RACW_Type, used in the PolyORB version.
30126 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30127 version and the GARLIC version.
30129 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30130 Rename RCI_Info to RCI_Locator for better consistency between the
30131 GARLIC and PolyORB versions of the distributed systems annex.
30132 (DSA_Implementation_Name): This enumeration lists the possible
30133 implementations of the Partition Communication Subsystem for the
30134 Distributed Systems Annex (DSA). The three available implementations
30135 are the dummy stub implementation (No_DSA), and two versions based on
30136 two different distribution runtime libraries: GARLIC and PolyORB. Both
30137 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30139 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30142 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30143 between the GARLIC and PolyORB versions of the distributed systems
30145 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30147 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30149 * gnat1drv.adb: Suppress calling the back end when
30150 Frontend_Layout_On_Target is true.
30152 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30154 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30155 Set_Read_Only): New subprograms.
30156 These new routines allow the user to set or unset the Owner execute
30157 and Owner write permission flags on a file.
30159 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30160 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30162 2004-10-26 Matthew Gingell <gingell@gnat.com>
30164 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30166 2004-10-26 Pascal Obry <obry@gnat.com>
30168 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30169 memory before the faulting page we properly test the process read
30170 access for this address using appropriate Win32 routine.
30171 (HPUX sections): guard with "__hpux__" instead of "hpux".
30173 2004-10-26 Robert Dewar <dewar@gnat.com>
30175 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30176 entry parameter if pragma Unreferenced set, since we do not properly
30177 handle the case of multiple parameters.
30179 2004-10-26 Vincent Celier <celier@gnat.com>
30181 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30182 (Ada_Objects_Path.Add): For a library project, add to the object path
30183 the library directory only if there is no object directory or if the
30184 library directory contains ALI files.
30185 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30187 2004-10-26 Vincent Celier <celier@gnat.com>
30189 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30190 extension of library projects.
30192 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30193 path defaults to ".:<prefix>/lib/gnat".
30194 (Parse): For an extending all project, allow direct import of a project
30195 that is virtually extended.
30197 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30198 the specified name is directly imported, return its ID. Otherwise, if
30199 an extension of this project is imported, return the ID of the
30202 2004-10-26 Robert Dewar <dewar@gnat.com>
30204 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30205 (Sub3): New procedure, used by Scaled_Divide
30206 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30207 correct more than one instance of failure to propagate carries
30209 (Double_Divide): Handle overflow case of largest negative number
30210 divided by minus one.
30212 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30213 the case of a quotient value out of range.
30216 2004-10-26 Robert Dewar <dewar@gnat.com>
30218 * s-bitops.adb (Bit_Eq): Remove redundant check.
30220 * s-bitops.ads: Minor comment updates
30221 Change some occurrences of Address to System.Address
30223 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30225 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30227 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30228 accessibility check to prefix that is a protected operation.
30230 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30232 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30233 empty, post message on stub.
30235 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30236 Javier Miranda <miranda@gnat.com>
30238 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30239 current instance appears within a unit that is directly in the context
30241 Used to determine whether the body of the instance should be analyzed
30242 immediately after its spec, to make its subprogram bodies available
30243 for front-end inlining.
30244 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30245 constraint is not allowed on the component type (AARM 12.5.3(3))
30247 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30249 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30250 'Storage_Pool): enhance, document & limit detection of non-sharable
30253 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30255 * s-pooglo.ads: Add more documentation now that this pool is properly
30258 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30260 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30261 or protected type with discriminants, do not constrain the
30262 corresponding record type if the subtype declaration has no
30263 discriminant constraints. This can be the case in source code, or in
30264 the subtype declaration created to rename an actual type within an
30267 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30269 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30270 different kind of stub (possibly wrong name for file), do not check
30272 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30273 includes call to some function that returns an unconstrained type, do
30276 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30278 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30279 appear in the code for the main unit. Dependencies among units in the
30280 context of the main unit are established when those other units are
30281 compiled. Otherwise spurious elaboration constraints can generate
30282 incorrect elaboration circularities.
30284 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30285 Ed Schonberg <schonberg@gnat.com>
30287 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30288 subprogram is called with a parameter that is not an object name. This
30289 situation arises for some cases of illegal code, which is diagnosed
30290 later, and in this case it is wrong to call Is_Aliased, as that might
30291 cause a compiler crash.
30292 (Explain_Limited_Type): Refine previous fix to include
30293 inherited components of derived types, to provide complete information.
30295 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30296 is the prival for a protected object.
30297 It is necessary to mark this entity as a variable, in addition to
30298 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30299 modified to avoid checking the Aliased flag on entities that are not
30300 objects. (Checking that flag for non-objects is erroneous and could
30301 lead to a compiler crash).
30303 2004-10-26 Robert Dewar <dewar@gnat.com>
30305 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30306 X_Frac = 0.5, then we know that the number X must be positive.
30307 (Succ): Remove the same redundant test, and also fix the primary test
30308 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30310 (Decompose): Add fuller comments to spec
30312 2004-10-26 Pascal Obry <obry@gnat.com>
30314 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30315 validity (process must have read access). Set to 0 in all other cases.
30316 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30317 violation on Win32.
30318 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30319 segmentation violation.
30321 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30323 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30324 whose type is a constructed subtype of an aliased object with an
30325 unconstrained nominal subtype, convert the actual to the constructed
30326 subtype before taking its address.
30328 2004-10-26 Vincent Celier <celier@gnat.com>
30330 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30331 (Is_Path_Name_Case_Sensitive): New function
30333 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30334 (Base_Name, Simple_Name, Current_Directory, Compose,
30335 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30338 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30339 Vasiliy Fofanov <fofanov@act-europe.fr>
30340 Vincent Celier <celier@gnat.com>
30342 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30343 "memory management issues" section and document some of the useful
30344 memory pools provided as part of the GNAT library.
30345 Remove "virtual" from declaration of A::method2 in
30346 the simple example of Ada/C++ mixed system.
30347 Library Projects may be virtually extended: their virtual extensions
30348 are not Library Projects.
30349 Added section on extending project hierarchies.
30351 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30353 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30355 (__gnat_portable_spawn): Remove const.
30357 * mingw32.h (MAXPATHLEN): Check for previous definition.
30359 2004-10-17 Matthias Klose <doko@debian.org>
30361 * gnatvsn.ads: Set gnat library version to 4.0.
30363 2004-10-05 Vincent Celier <celier@gnat.com>
30365 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30367 2004-10-04 Laurent Guerby <laurent@guerby.net>
30370 * Makefile.in: Define and use RANLIB_FLAGS.
30372 2004-10-04 Pascal Obry <obry@gnat.com>
30374 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30375 other x86 platforms).
30377 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30379 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30380 in general and triggers stack alignment adjustment for thread entry
30381 points on targets where this is necessary.
30383 2004-10-04 Bernard Banner <banner@gnat.com>
30386 * Makefile.in: Add section for powerpc linux
30387 Add variant i-vxwork-x86.ads
30389 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30391 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30393 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30394 table registration calls when need be. Ensures no reference to the crt
30395 ctors symbol are issued in the SJLJ case, which avoids possible
30396 undefined symbol errors in the case of modules to be statically linked
30399 2004-10-04 Javier Miranda <miranda@gnat.com>
30401 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30402 in-line the code corresponding to subprogram Analyze_Actuals. In
30403 addition, analyze the actuals only in case of subprogram call.
30405 2004-10-04 Ed Falis <falis@gnat.com>
30407 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30409 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30411 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30412 in the documentation.
30414 2004-10-04 Robert Dewar <dewar@gnat.com>
30416 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30418 (Analyze_Block_Statement): Add circuitry to detect following dead code
30419 (Check_Unreachable_Code): Handle case of block exit
30421 2004-10-04 Robert Dewar <dewar@gnat.com>
30423 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30424 (XMatchD): Avoid warning for Logic_Error call
30426 2004-10-04 Robert Dewar <dewar@gnat.com>
30428 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30429 consider expressions buried within a procedure actual to be an actual.
30430 This caused some blowups with uses of packed slices within a procedure
30433 2004-10-04 Robert Dewar <dewar@gnat.com>
30435 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30436 longer need to be initialized to zero.
30437 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30438 initialized to zero.
30440 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30441 considered valid, even if the representation is modular. That's correct
30442 now that we no longer initialize packed modular arrays to zero.
30444 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30445 suffixes. These are now documented as the only cases in which the
30446 debugger ignores outer records.
30447 Previously, the spec allowed arbitrary suffixes for this purpose.
30448 Change name of LJM to JM for packed array pad records
30449 Create separate section on packed array handling, and add a whole new
30450 set of comments to this section describing the situation with packed
30451 modular types and justification requirements depending on endianness.
30453 2004-10-04 Robert Dewar <dewar@gnat.com>
30455 * a-except.adb: Add a comment for last change
30457 * einfo.ads: Minor spelling correction in comment
30459 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30461 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30464 * sem_util.ads: Minor comment update
30466 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30468 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30469 Inline_Always when in Configurable_Run_Time mode.
30471 * sem_prag.adb (Process_Convention): If entity is an inherited
30472 subprogram, apply convention to parent subprogram if in same scope.
30473 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30474 when in Configurable_Run_Time mode.
30476 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30478 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30479 class_wide type after component list has been inherited.
30481 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30483 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30484 Denotes_Previous_Actual, to handle properly the case of a private
30485 actual that is also the component type of a subsequent array actual.
30486 The visibility status of the first actual is not affected when the
30487 second is installed.
30488 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30489 make fully recursive the treatment of formals of packages declared
30491 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30492 the above on exit from an instantiation.
30493 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30494 current instantiation which is now complete.
30495 (Analyze_Package_Instantiation): No instantiated body is needed if the
30496 main unit is generic. Efficient, and avoid anomalies when a instance
30497 appears in a package accessed through rtsfind.
30499 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30501 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30502 do not generate a declaration for a temporary if the call is part of a
30503 library-level instantiation.
30505 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30507 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30508 searching for a limited component to flag.
30510 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30511 expansion of Input, to account for the fact that the implicit call
30512 generated by the attribute reference must freeze the user-defined
30513 stream subprogram. This is only relevant to 'Input, because it can
30514 appear in an object declaration, prior to the body of the subprogram.
30516 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30517 expansion can proceed and further errors uncovered.
30518 (Minor clean up): Fix cases of using | instead of \ for continuation
30521 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30523 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30525 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30526 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30527 Use gcc_assert and gcc_unreachable.
30529 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30530 specified alignment before validating size.
30531 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30532 stripped-down declaration for the type of the inner field when making
30535 * utils.c (finish_record_type): Do not compute the size in units
30536 incrementally. Instead compute it once for the rep clause case.
30537 Use gcc_assert and gcc_unreachable.
30539 2004-10-04 Vincent Celier <celier@gnat.com>
30541 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30543 (Is_Valid_Path_Name): Take '/' as a directory separator.
30545 2004-10-04 Vincent Celier <celier@gnat.com>
30547 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30548 (Extended_Project) only if Extended_Project is defined, to avoid
30550 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30552 (Parse_Single_Project): Ditto.
30554 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30555 Add_To_Project_Path for virtual projects.
30557 2004-10-04 Vincent Celier <celier@gnat.com>
30559 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30561 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30562 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30563 parameter Options_2.
30565 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30566 Build_Dynamic_Library with an empty Options_2.
30568 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30571 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30572 directory separator, if any.
30573 (Gprmake): Do not allow mains on the command line for library projects.
30574 Do not attempt to link when the project is a library project.
30575 (Library_Opts): New table to store Library_Options.
30576 (Build_Library): If Library_Options is specified, pass these options
30577 when building a shared library.
30579 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30581 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30582 the end of this procedure now that the unlock operation was inserted
30585 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30587 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30588 corresponding to the Preallocated_Stacks flags in System.
30589 (Get_Target_Parameters): Including the processing for
30590 Preallocated_Stacks.
30592 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30593 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30597 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
30598 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30599 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30600 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30601 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30602 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30603 used to signal whether the compiler creates the required stacks and
30604 descriptors for the different tasks (when True) or it is done by the
30605 underlying operating system at run time (when False).
30606 It is initially set to False in all targets.
30608 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30609 if it is supported by the target.
30610 (Make_Task_Create_Call): Pass the stack address if it has been
30611 previously created. Otherwise pass a Null_Address.
30613 * snames.adb: Add _stack.
30615 * snames.ads: Add Name_uStack. Required to allow the expander to
30616 statically allocated task stacks.
30618 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30619 Stack_Address argument.
30620 Check that its value is equal to Null_Address because this target does
30621 not support the static stack allocation.
30623 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30625 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30628 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30630 * exp_dist.adb: Split declaration of asynchronous flag out of
30631 Add_RACW_Read_Attribute.
30632 Minor reformatting for better alignment with PolyORB version.
30633 Store the entity for the asynchronous flag of an RACW, rather than the
30634 expression, in the asynchronous flags table. This will allow this flag
30635 to be used in other subprograms beside Add_RACW_Read_Attribute.
30637 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30639 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30640 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30641 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30642 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30643 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30644 sockets constant MSG_NOSIGNAL (Linux-specific).
30645 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30646 all Send operations.
30647 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30648 from trigerring SIGPIPE.
30649 Rename components to avoid clash with Ada 2005 possible reserved
30651 (Check_Selector): When the select system call returns with an error
30652 condition, propagate Socket_Error to the caller.
30654 2004-10-01 Jan Hubicka <jh@suse.cz>
30656 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30658 2004-09-23 Robert Dewar <dewar@gnat.com>
30661 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30662 instead do this at freeze time (we won't do it if there is an address
30664 Change "pragma inline" to "pragma Inline" in information and error
30666 Minor reformatting.
30668 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30669 right way of doing things after all.
30670 (Freeze_Entity): For object, set Is_Public for imported entities
30671 unless there is an address clause present.
30673 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30675 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30676 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30677 ensures proper handling of types with rep clauses, which might have
30678 their TYPE_SIZE set already.
30680 2004-09-21 Robert Dewar <dewar@gnat.com>
30682 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30683 packed array types in both little- and big-endian cases. This change
30684 ensures that we no longer count on the unused bits being initialized
30685 for such types (and in particular ensures that equality testing will
30686 only read the relevant bits).
30687 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30688 These changes mean that we no longer need to initialize small packed
30690 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30691 optimization to an LJM field as to its parent field.
30693 * ada-tree.h, trans.c, utils.c, utils2.c:
30694 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30696 2004-09-20 Jan Hubicka <jh@suse.cz>
30698 * utils.c (gnat_finalize): Remove.
30699 (end_subprog_body): Directly call cgraph_finalize_function;
30700 do not lower the nested functions.
30702 2004-09-20 Robert Dewar <dewar@gnat.com>
30705 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30706 if an address clause is present, since that means that the Import
30709 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30711 * 5tsystem.ads: Removed, no longer used.
30713 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30714 Zack Weinberg <zack@codesourcery.com>
30716 * ada-tree.def: Use tree_code_class enumeration constants
30717 instead of code letters.
30718 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30719 Update for new tree-class enumeration constants.
30721 2004-09-17 Vincent Celier <celier@gnat.com>
30723 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30724 capabilities of the general project manager.
30726 2004-09-09 Vincent Celier <celier@gnat.com>
30728 * a-direct.ads: Add pragma Ada_05
30729 (Directory_Entry_Type): Give default value to component Kind to avoid
30730 not initialized warnings.
30732 * a-direct.adb (Current_Directory): Remove directory separator at the
30734 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30735 an existing directory.
30736 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30737 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30738 Convert the result to File_Size.
30740 * prj.ads: (Project_Error): New exception
30742 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30743 Prj.Com, not from Osint.
30744 (Attrs, Package_Attributes): Tables moved to private part of spec
30745 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30747 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30748 Prj.Project_Error after call to Fail.
30749 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30750 Fail. Check that package name is not already in use.
30752 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30753 used by tools, not only by the project manager, and to indicate that
30754 exception Prj.Prj_Error may be raised in case of problem.
30755 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30757 (Attrs, Package_Attributes): Table instantiations moved from the body to
30758 the private part to be accessible from Prj.Attr.PM body.
30760 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30761 from new package Prj.Attr.PM.

30818 raise Program_Error if called from a protected operation.
30820 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30821 the protected action nesting level.
30822 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30823 protected action nesting level.
30824 (Unlock): When pragma Detect_Blocking is active decrease the protected
30825 action nesting level.
30827 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30828 Protected_Action_Nesting.
30830 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30831 Common_ATCB record. It contains the dynamic level of protected action
30832 nesting for each task. It is needed for checking whether potentially
30833 blocking operations are called from protected operations.
30834 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30835 Detect_Blocking is active or not in the partition.
30837 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30869 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30870 insertion of the statement raising Program_Error. The run time
30871 contains the required machinery for handling that.
30873 * sem_util.ads: Change comment associated to procedure
30874 Check_Potentially_Blocking_Operation.
30875 This procedure does not insert a call for raising the exception because
30876 that is currently done by the run time.
30878 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30880 * init.c: Add the global variable __gl_detect_blocking that indicates
30881 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30882 making the pragma available at run time.
30883 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30886 pragma Detect_Blocking is active.
30888 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30890 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30891 DB is found in the ali file. Any unit compiled with pragma
30892 Detect_Blocking active forces its effect in the whole partition.
30894 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30895 Detect_Blocking is active and delay is called from a protected
30898 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30899 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30900 Detect_Blocking is active (0 otherwise).
30901 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30902 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30907 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30908 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30911 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30912 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30913 Update API in placeholder implemetation of s-parint to reflect changes
30914 in distribution runtime library.
30916 * sem_ch3.adb (Expand_Derived_Record): Rename to
30917 Expand_Record_Extension.
30919 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30920 primitive operations of potentially distributed object types that have
30921 non-controlling anonymous access formals.
30923 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30925 New implementation of expansion for remote access-to-subprogram types,
30926 based on the RACW infrastructure.
30927 This version of sem_dist is compatible with PolyORB/DSA as well as
30930 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30931 Asynchrronous that applies to a remote access-to-subprogram type, mark
30932 the underlying RACW type as asynchronous.
30934 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30935 __gnat_using_gnu_linker to 1.
30937 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30938 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

30944 * exp_ch3.adb (Expand_Derived_Record): Rename to
30945 Expand_Record_Extension.
30946 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30947 a component declaration must remain attached at that point in the
30948 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30949 It is therefore necessary to take a copy of the expression when building
30950 the corresponding assignment statement in the init proc.
30951 As a side effect, in the case of a derived record type, we now see the
30952 original expression, without any rewriting that could have occurred
30953 during expansion of the ancestor type's init proc, and we do not need
30954 to go back to Original_Node.
30956 * exp_ch3.ads (Expand_Derived_Record): Rename to
30957 Expand_Record_Extension.

30964 subprogram. The proxy object is used as the designated object
30965 for RAS values on the same partition (unless All_Calls_Remote applies).
30966 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30967 System.Partition_Interface.Get_Unique_Remote_Pointer.
30968 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):

30972 New implementation of expansion for remote access-to-subprogram types,
30973 based on the RACW infrastructure.
30975 * exp_dist.ads (Copy_Specification): Update comment to note that this
30976 function can copy the specification from either a subprogram
30977 specification or an access-to-subprogram type definition.
30979 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30981 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30982 in an instance, between an explicit subprogram an one inherited from a
30983 type derived from an actual.
30985 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30986 add a polling call if the subprogram is to be inlined by the back-end,
30987 to avoid repeated calls with multiple inlinings.
30989 * checks.adb (Apply_Alignment_Check): If the expression in the address
30990 clause is a call whose name is not a static entity (e.g. a dispatching
30991 call), treat as dynamic.
30993 2004-09-09 Robert Dewar <dewar@gnat.com>
30995 * g-trasym.ads: Minor reformatting
30997 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31006 2004-09-09 Pascal Obry <obry@gnat.com>
31008 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31009 enable map file generation. Add the right option to generate the map
31010 file if Map_File is set to True.
31012 * gnatdll.adb (Gen_Map_File): New variable.
31013 (Syntax): Add info about new -m (Map_File) option.

31041 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31042 of variable length temporaries for function return now that the
31043 back-end and gigi support it.

31094 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
31095 packed indexed component where array is an IN OUT formal. This
31096 generated garbage code previously.

31115 expander is not active (but check for unset reference to prefix of
31118 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31119 pragma Debug as an if statement with a constant condition, for
31120 consistent treatment of entity references contained within the
31121 enclosed procedure call.
31123 2004-09-01 Vincent Celier <celier@gnat.com>
31125 * bindgen.adb: (Set_EA_Last): New procedure
31126 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

31150 2004-09-01 Pascal Obry <obry@gnat.com>
31152 * gprcmd.adb (Extend): Do not output trailing directory separator. This

31157 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31158 target names rewrite to fix regressions with recent version of

31210 2004-08-16 Pascal Obry <obry@gnat.com>
31212 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31213 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31214 option and not mdll anymore. Update comment.
31216 2004-08-16 Pascal Obry <obry@gnat.com>
31218 * bld.adb (Put_Include_Project): Properly handle directory separators
31221 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31234 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31236 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31237 for a global aliased object with a variable size and an unconstrained
31238 nominal subtype, pretend there is no initializer if the one we have is
31239 incomplete, and avoid referencing an inexistant component in there. The
31240 part we have will be rebuilt anyway and the reference may confuse
31241 further operations.
31243 2004-08-13 Thomas Quinot <quinot@act-europe.fr>
31245 * einfo.ads: Minor reformatting
31247 * lib-writ.adb (Output_Main_Program_Line): Do not set parameter

33227 hand side. Warnings are now properly emitted when variables or prefixes
33228 are assigned but not read.

33235 "variable ... is assigned but never read" since other entities may read
33236 the memory location.

33892 Merge from tree-ssa-20020619-branch.
33894 * config-lang.in (boot_language, build_by_default): Set

33931 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33932 Analyze on the library unit node after generation of distribution stub
33933 constructs. The call was a no-op because Unit_Node has already been
33934 Analyzed, and the tree fragments for the distribution stubs are
33935 analyzed as they are inserted in Exp_Dist.
33936 Update comment regarding to distribution stubs to reflect that we
33937 do not generate stub in separate files anymore.

33955 has been rewritten as an explicit dereference, retrieve type of
33956 original node to check for possibly unconstrained record type.
33958 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33960 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33961 overriding, use the operation of the parent unconditionally.
33963 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33964 operation when either operand is a literal, to avoid further
33967 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33968 overridden by a previous explicit declaration, mark the previous entity
33971 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33972 Is_Visibly_Controlled, to determine whether a declaration of a
33973 primitive control operation for a derived type overrides an inherited
33974 one. Add warning if the explicit declaration does not override.
33976 2004-05-10 Vincent Celier <celier@gnat.com>
33978 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33979 some cases when the sources are no longer present.
33981 * make.adb (Collect_Arguments): Fail if an external source, not part
33982 of any project need to be compiled, when switch -x has not been
33985 * makeusg.adb: Document new switch -x
33987 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33988 defaulted to False.

33992 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33993 gnatmake switch -x.
33995 * gnat_ugn.texi: Document new gnatmake switch -x
33997 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
33999 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34001 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34002 (process_attributes): Likewise.
34004 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34006 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34008 2004-05-10 Robert Dewar <dewar@gnat.com>
34010 * gnat_ugn.texi: Document that for config pragma files, the maximum
34011 line length is always 32767.
34013 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34014 literals is now allowed.
34016 * gnat-style.texi: Remove statement about splitting long lines before
34017 an operator rather than after, since we do not follow this rule at all.
34018 Clarify rule (really lack of rule) for spaces around exponentiation
34020 * sem_elim.adb: Allow concatenation of string literals as well as a
34021 single string literal for pragma arguments.
34023 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34025 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34026 written for append case.
34028 * frontend.adb: Changes to avoid checking max line length in config
34031 * g-os_lib.ads: Minor reformatting
34033 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34034 wrong in any case. Instead use standard value. Noticed during code
34037 * opt.ads (Max_Line_Length): New field, used to implement removal of
34038 limitation on length of lines when scanning config pragma files.
34040 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34041 makeutl.ads, makeutl.adb: Minor reformatting
34043 * scn.adb: Do not check line length while scanning config pragma files

35226 * sinfo.ads: Fix typo in commment.

35232 as is done for non-private derived record types.
35234 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35235 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35236 candidate interpretation in an overloaded call.

35239 expression is Null and target type is not an access type (e.g. a

35250 complete assignment subtree which is now unnecessary, as the expansion
35251 of inlined call has been improved to preserve a consistent assignment
35252 tree. Note_Possible_Modification must be called only
35253 after checks have been applied, or else unnecessary checks will
35256 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35257 of explicit dereferences that do not Come_From_Source:
35258 - be selective on cases where we must go back to the dereferenced
35259 pointer (an assignment to an implicit dereference must not be
35260 recorded as modifying the pointer);
35261 - do not rely on Original_Node being present (Analyze_Assignment
35262 calls Note_Possible_Modification on a copied tree).
35264 * sem_warn.adb (Check_References): When an unset reference to a pointer
35265 that is never assigned is encountered, prefer '<pointer> may be null'
35266 warning over '<pointer> is never assigned a value'.

35335 a string literal, create a temporary for it, constant folding only
35336 handles scalars here.

35529 information for protected (wrapper) operation as well, to simplify gdb
35532 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35575 a classwide type (for which Is_Object_Reference holds), but it can
35576 also be a value conversion for an access-to-classwide type. In the
35577 latter case, there is an implicit dereference, and the original node
35578 for the prefix does not verify Is_Object_Reference.

35664 gigi has enough information to construct the record, and there is no
35665 place in the tree for the declaration.
35667 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35668 serial number for the dummy body that is built for analysis, to avoid
35669 inconsistencies in the generation of internal names when compiling
35672 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35674 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35677 2004-03-22 GNAT Script <nobody@gnat.com>
35679 * Make-lang.in: Makefile automatically updated
35681 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35683 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35684 * trans.c (tree_transform, emit_index_check): Likewise.
35685 * utils.c (build_template): Likewise.
35686 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35687 (maybe_unconstrained_array, unchecked_convert): Likewise.

35706 Minor reformatting.
35708 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35710 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35711 as regular exception objects and not as mere integers representing the
35712 condition code. The latter approach required some dynamics to mask off
35713 severity bits, which did not fit well into the GCC table based model.
35714 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35715 exception data objects. We don't it and it would conflict with the other
35716 external symbol we have to generate for such exceptions.
35718 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35719 the special code for VMS exceptions, since these are now represented
35720 as regular exceptions objects.
35722 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35724 * decl.c (debug_no_type_hash): Remove.

35728 2004-03-19 Laurent Guerby <laurent@guerby.net>
35730 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35731 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35733 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35735 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35736 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.

35739 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35740 TYPE_VALUES, not TYPE_FIELDS.

35753 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35755 * adaint.c: Update comments.
35757 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35758 GNATLIB_SHARED for FreeBSD.
35760 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35762 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35763 When needed (stack checking) the stack size is retrieved
35764 from the VxWorks kernel.
35766 * Makefile.in: Flag -nostdinc is required when building the run time
35767 for avoiding looking for files in the base compiler.
35768 Add the VxWorks specific version of the package body for
35769 System.Stack_checking.Operations (5zstchop.adb).
35771 * Make-lang.in: Add the object file for
35772 System.Stack_Checking.Operations.

35780 checking from this package to package System.Stack_Checking.Operations.
35781 This way, stack checking operations are only linked in the final
35782 executable when using the -fstack-check flag.
35784 2004-03-18 Doug Rupp <rupp@gnat.com>
35786 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35796 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35797 the procedures Add_To_Path_File.
35798 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35799 making sure that each directory is present only once and, for object
35800 dirs, when a directory already present is added, the duplicate is
35801 removed and the directory is always put as the last in the table.
35802 Write the path files at the end of these accumulations.
35804 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35805 Files_Htable for all sources.
35807 * prj-proc.adb (Process): Remove restrictions between not directly
35808 related extending projects.

35816 parameter Trusted_Mode.
35818 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35820 * scn.adb (Determine_License): Take into account a degenerated case
35821 when the source contains only comments.
35823 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35825 * sem_warn.adb (Check_References): For a warning on a selected
35826 component that does not come from source, locate an uninitialized
35827 component of the record type to produce a more precise error message.
35829 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35831 * 3zsoccon.ads: Fix multicast options.
35833 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35836 2004-03-15 Robert Dewar <dewar@gnat.com>

35839 pragma used for a private type.
35841 * lib-xref.adb (Generate_Reference): Do not generate warning if
35842 reference is in a different unit from the pragma Unreferenced.
35844 * 5vtpopde.adb: Minor reformatting
35845 Fix casing of To_Task_ID
35847 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35848 flag if we have an unchecked conversion to an access type in the same
35851 2004-03-15 Geert Bosch <bosch@gnat.com>
35853 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35854 imaginary parts, use Double precision throughout.
35856 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35857 we want to be able to compile run-time with -gnata for testing, but
35858 this may also be instantiated in user code that is compiled with -gnata.
35860 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35862 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35863 codes. Having a separate type for this is useful to enforce consistency
35864 throughout the various run-time units.
35865 (Exception_Data): Use Exception_Code for Import_Code.
35867 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35875 component, now reflected by an exported accessor.
35876 (is_handled_by): New routine to compute whether the propagated
35877 occurrence matches some handler choice specification. Extracted out of
35878 get_action_description_for, and expanded to take care of the VMS
35880 (get_action_description_for): Use is_handled_by instead of an explicit
35881 complex condition to decide if the current choice at hand catches the
35882 propagated occurrence.
35884 * raise.h (Exception_Code): New type for C.
35886 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35887 System.Standard_Library.Exception_Code, to allow references from the
35888 pragma import/export expander.
35890 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35891 New accessors to allow easy access to GNAT exception data
35893 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35894 redundant Handled_By_Others component, helper for the personality
35895 routine which will now be able to call the appropriate exception data
35898 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35899 component of Standard_Exception_Type to be the closest possible to
35900 Exception_Code in System.Standard_Library, that we cannot get at this
35901 point. Expand a ??? comment to notify that this type node should
35902 probably be rewritten later on.
35904 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35905 registration call to include a pointer to the exception object in the
35908 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35909 instead of int and explicit bitmasks.
35911 2004-03-15 Vincent Celier <celier@gnat.com>
35913 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35914 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35916 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35917 longer needed now that it is in the spec of
35918 System.Tasking.Task_Attributes.
35920 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35922 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35924 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35926 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35927 taken care of in Scan_Make_Arg.
35928 (Scan_Make_Arg): Add the executable suffix only if the argument
35929 following -o, in canonical case, does not end with the executable
35930 suffix. When in verbose mode and executable file name does not end
35931 with executable suffix, output the executable name, in canonical case.
35933 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35934 to avoid warnings when instantiating Ada.Task_Attributes.
35937 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35938 in the correct order.
35940 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35948 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35950 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35951 tagged type is inherited, and the parent operation is not frozen yet,
35952 force generation of a freeze node for the inherited operation, so the
35953 corresponding dispatch entry is properly initialized.
35954 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35955 when looking for user-defined equality operation.
35957 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35958 boolean when locating primitive equality of tagged component.
35960 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35962 a temporary before expanding assignment into a loop.
35964 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35965 priority in full, to ensure that any expanded subepxressions of it are
35966 elaborated in the scope of the init_proc.

35969 after object declaration, skipping over code that may have been
35970 generated for validity checks.
35972 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35973 discriminants, ignore the known discriminants of its full view, if
35974 any, to check legality.
35976 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35977 component if type has unknown discriminants.
35978 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35979 null if type has unknown discriminants.
35981 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35982 for end label when present.
35984 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35985 temporary file, rather than an empty string.
35987 2004-03-15 Ed Falis <falis@gnat.com>
35989 * s-thread.adb: Removed, no longer used.

36011 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36012 Insert_Dereference_Action when rewriting an implicit dereference into
36013 an explicit one, this will be taken care of during expansion of the
36014 explicit dereference.
36015 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36016 of non-packed slices, since the dereference action generated by
36017 expansion of the explicit dereference is needed in any case.
36018 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36019 analyze and resolve the rewritten explicit dereference so it is seen
36021 (Insert_Dereference_Action): This procedure is now called only for the
36022 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36023 dereferences that do not come from source (including explicit
36024 dereferences resulting from rewriting implicit ones), but do not
36025 recursively insert a check for the dereference nodes contained within
36027 (Insert_Dereference_Action): Clarify and correct comment.

36904 checks for bitfield creation are triggered.
36905 (finish_record_type): During last pass over the fields, clear
36906 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37293 be modified by the binder generated main program if the -D switch is
37296 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37297 imported functions (since now we expect this to be done for imported
37300 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37301 Minor reformatting throughout
37303 * 5zinit.adb: Minor reformatting

37307 doing reformatting)
37309 * sprint.adb: Minor updates to avoid -gnatwa warnings
37311 * s-secsta.ads, s-secsta.adb:
37312 (SS_Get_Max): New function to obtain high water mark for ss stack
37313 Default_Secondary_Stack is not a constant since it may be modified by
37314 the binder generated main program if the -D switch is used.
37316 * switch-b.adb: New -Dnnn switch for binder
37319 Make -gnatg imply all warnings currently in -gnatwa

37350 Acquire new SS indication of secondary stack use from ali files
37352 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37353 (since now we expect this to be done for imported functions)
37355 * bindgen.adb: Generate call to modify default secondary stack size if
37358 * bindusg.adb: Add line for new -D switch
37360 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37361 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37362 Add circuitry for both records and arrays to avoid gigi
37363 processing if the type involved has non-bit-aligned components
37365 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37366 N_String_Literal node always references an E_String_Literal_Subtype
37367 entity. This may not be true in the future.
37368 (Possible_Bit_Aligned_Component): Move processing of
37369 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37371 * exp_ch6.adb (Expand_Thread_Body): Pick up
37372 Default_Secondary_Stack_Size as variable so that we get value modified
37373 by possible -Dnnn binder parameter.
37375 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37376 (Type_May_Have_Bit_Aligned_Components): New function.
37378 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37388 unless explicit Pure_Function pragma given, to avoid insidious bug of
37389 call to non-pure imported function getting eliminated.

37411 * rtsfind.adb (Load_Fail): Give full error message in configurable
37412 run-time mode if all_errors mode is set. This was not done in the case
37413 of a file not found, which was an oversight.
37414 Note if secondary stack unit is used by compiler.
37416 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37417 ineffective elaborate all pragmas on non-visible packages (this
37418 happened when a renamed subprogram was called). Now the elaborate all
37419 always goes on the package containing the renaming rather than the one
37420 containing the renamed subprogram.
37422 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37423 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37425 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37426 has an Etype that references an E_String_Literal.
37427 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37428 always references an E_String_Literal_Subtype entity. This may not
37429 be true in the future.
37431 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37434 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37437 2004-01-05 Ed Falis <falis@gnat.com>

37444 * bld.adb: Minor comment updates
37445 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37448 * make.adb (Gnatmake): Special process for files to compile/check when
37449 -B is specified. Fail when there are only foreign mains in attribute
37450 Main of the project file and -B is not specified. Do not skip bind/link
37451 steps when -B is specified.
37453 * makeusg.adb: Document new switch -B

37476 -gnatwa warning on static condition.
37478 2004-01-05 Doug Rupp <rupp@gnat.com>

37482 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37484 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37485 all attributes, including read-only attribute.
37487 2004-01-05 Pascal Obry <obry@gnat.com>

37490 library naming scheme.
37492 * mlib-prj.adb (Build_Library): Generate different names for the static
37493 or dynamic version of the GNAT runtime. This is needed to support the
37494 new shared library naming scheme.

37496 based on the new naming scheme.
37498 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37499 scheme for the shared runtime libraries.
37502 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37504 (install-gnatlib): Do not create symlinks for shared libraries.
37505 (gnatlib-shared-default): Idem.
37506 (gnatlib-shared-dual-win32): New target. Not used for now as the
37507 auto-import feature does not support arrays/records.
37508 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37509 (gnatlib-shared-vms): Fix shared runtime libraries names.
37511 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37512 dependent runtime shared library name.
37514 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37516 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37519 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37521 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37522 protected objects when allocator has a subtype indication, not a
37523 qualified expression. Note that qualified expressions may have to be
37524 checked when limited aggregates are implemented.
37526 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37527 pure, emit warning.
37528 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37529 subprogram is imported, remove warning.
37531 2004-01-05 Geert Bosch <bosch@gnat.com>
37533 * s-poosiz.adb: Update copyright notice.
37534 (Allocate): Use Task_Lock to protect against concurrent access.
37535 (Deallocate): Likewise.

37573 * cstand.adb (Create_Standard): Change the way how the declaration of
37574 the Duration type is created (making it the same way as it is for all
37575 the other standard types).
37577 2003-12-17 Robert Dewar <dewar@gnat.com>
37579 * s-crtl.ads: Fix header format
37580 Change Pure to Preelaborate

37585 the expression type only if it is declared in the current unit.
37587 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37588 are universal and already analyzed, as can occur in constrained
37589 subcomponents that depend on discriminants, when one constraint is a
37592 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37593 type Any_Fixed is legal as the argument of a conversion, if only one
37594 fixed-point type is in context.

37607 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37608 (Gnatchop): Do not set failure status when reporting the number of
37611 2003-12-15 Doug Rupp <rupp@gnat.com>
37613 * s-ctrl.ads: New file.

37633 * Make-lang.in: Makefile automatically updated
37635 2003-12-11 Ed Falis <falis@gnat.com>
37637 * 5zinit.adb: Clean up.
37639 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37640 to __gnat_map_signal, imported from init.c to support

37673 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37674 Minor reformatting throughout
37676 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37678 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37679 bounds of a loop, create a separate block in order to generate proper
37680 cleanup actions to prevent memory leaks.
37682 * sem_res.adb (Resolve_Call): After a call to
37683 Establish_Transient_Scope, the call may be rewritten and relocated, in
37684 which case no further processing is needed.
37686 * sem_util.adb: (Wrong_Type): Refine previous fix.
37687 Fixes ACATS regressions.
37690 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37693 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37695 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37696 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37699 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37702 2003-12-08 Robert Dewar <dewar@gnat.com>
37704 * 7sintman.adb: Minor reformatting
37706 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37707 standard linker options to get standard libraries linked. We now plan
37708 to provide dummy versions of these libraries to match the appropriate
37709 configurable run-time (e.g. if a library is not needed at all, provide
37710 a dummy empty library).
37712 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37713 options (-L parameters and standard libraries). What we plan to do is
37714 to provide dummy libraries where the libraries are not required.
37716 * gnatbind.adb: Minor comment improvement
37718 2003-12-08 Javier Miranda <miranda@gnat.com>
37720 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37721 aggregate in the parent. Otherwise constants with limited aggregates
37722 are not supported. Add new formal to pass the component type (Ctype).
37723 It is required to call the corresponding IP subprogram in case of
37724 default initialized components.
37725 (Gen_Assign): In case of default-initialized component, generate a
37726 call to the IP subprogram associated with the component.
37727 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37728 of aggregate with default initialized components.
37729 (Has_Default_Init_Comps): Improve implementation to recursively check
37730 all the present expressions.
37732 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37733 to indicate that the initialization call corresponds to a
37734 default-initialized component of an aggregate.
37735 In case of default initialized aggregate with tasks this parameter is
37736 used to generate a null string (this is just a workaround that must be
37737 improved later). In case of discriminants, this parameter is used to
37738 generate a selected component node that gives access to the discriminant
37741 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37742 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37743 allocated aggregates with default-initialized components.
37745 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37746 the box notation is used in positional aggregates.

37760 * prj-dect.adb: Manage comments for the different declarations.
37762 * prj-part.adb (With_Record): New component Node
37763 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37764 Set the scanner to return ends of line and comments as tokens, if
37765 Store_Comments is True.
37766 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37767 comments are associated with these nodes. Store the node IDs in the
37769 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37771 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37772 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37773 current project. Call Tree.Restore afterwards. Set the various nodes
37774 for comment storage (Next_End, End_Of_Line, Previous_Line,
37777 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37778 defaulted to False.
37780 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37781 to False. When Truncated is True, truncate the string, never go to the
37783 (Write_End_Of_Line_Comment): New procedure
37784 (Print): Process comments for nodes N_With_Clause,

39527 a subunit is missing.
39528 (Instantiate_Subprogram_Body): If body of function is missing, set type
39529 of return expression explicitly in dummy body, to prevent cascaded
39530 errors when a subunit is missing.
39534 (Access_Subprogram_Declaration): Verify that return type is valid.
39538 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39543 (Corresponding_Discriminant): If the scope of the discriminant is a
39544 private type without discriminant, use its full view.

41569 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41570 function approach did not work well because of a side effect (the
41571 function call could reallocate the table which was being indexed
41572 using its result). Fixes ada/4851.

41631 Add 2001 to copyright date
41633 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

41850 When using a project file, fail if specified executable is relative
41851 path with directory information, and prepend executable, if not
41852 specified as an absolute path, with the exec directory. Make sure

41937 to Hbound, but no actual example of failure has been found.
41939 2001-12-17 Laurent Pautet <pautet@gnat.com>
41942 Fix comment of Shutdown_Socket and Close_Socket. These functions
41943 should not fail silently because if they are called twice, this
41944 probably means that there is a race condition in the user program.
41945 Anyway, this behaviour is consistent with the rest of this unit.
41946 When an error occurs, an exception is raised with the error message
41947 as exception message.

43281 instead of the previous simple checksum algorithm.
43282 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43283 (Set_Source_Table): idem.
43286 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43287 instead of simple checksum.
43288 (CRC_Match): new function.
43289 (CRC_Error): new constant.
43291 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43292 a CRC now and not a simple checksum. A CRC uses lower-case hex
43293 letters, fixes ambiguity in parsing.
43295 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43296 is what this variable will store.
43298 * bcheck.adb: Change reference to chechsum in comments by CRC.
43299 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43300 rename All_Checksum_Match to All_CRC_Match. Change due to API
43301 renaming since now GNAT does not use a simple checksum but a
43302 CRC using GNAT.CRC32.
43304 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43305 now and not anymore a simple checksum.

43342 Update comments for the CRC.
43344 * types.adb (Hex): Use lowercase for the letter part.
43346 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43347 for a word. This is currently used only for CRC. In previous version,
43348 the checksum was using a representation with all letter being
43349 upper-case. With the new implementation (using CRC) we do not remove
43350 the 32th bit of the CRC, so we can have an upper-case starting letter
43351 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43352 It is ambigous since the CRC was optional and could be followed by
43353 options like EB, EE. So now this routines uses lower-case letter for
43354 the hexadecimal representation. Strange enough only lower case letters
43355 where checked in Scan_ALI (even if this was not a possible case).
43357 * gnatvsn.ads (Library_Version): changed to 3.15a.
43359 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43362 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

43367 (Accumulate_Checksum): Modify to use System.CRC32.
43369 * ali-util.ads: Redo changes of previous revision to continue to use
43370 the word Checksum. Add 2001 to copyright notice.
