2024 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2025 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4115 which is the default in GNAT's persistent storage implementation.
4117 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4120 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4121 convention from its base type, do not set the type to that of integer,
4122 because it may inherit a size clause.

4164 (P_Access_Definition): Change the error message when parsing "access
4165 all" in Ada 95 mode. The message no longer forces the user to recompile

4186 the visible part of the spec of a remote types unit.

4188 New local subprogram Is_Valid_Remote_Object_Type, replaces
4189 Is_Recursively_Limited_Private.
4190 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4191 non-controlling formals (and the return type, even though this is not
4192 explicit in the standard) must support external streaming.
4193 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4194 as above for of RAS types and RCI subprograms. (The return type is not

4199 * sem_util.ads, sem_util.adb
4200 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4201 Is_Remote_Call_Interface to identify RACW types in a stable and
4202 consistent way. We used to rely in this predicate on the privateness of
4203 the designated type and its ancestors, but depending on the currently
4204 visible private parts, this caused false negatives. We now uniformly
4205 rely on checks made at the point where the RACW type is declared.

4219 Add missing escaping of all-caps word 'CPP' in error messages.
4220 (Build_Discriminated_Subtype): Do not inherit representation clauses
4221 from parent type if subtype already carries them, because they are
4222 inherited earlier during derivation and already include those that may
4223 come from a partial view.
4225 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4226 Check the declarations of a subprogram body for proper deferred

4260 (Add_One_Interp): Ignore any interpretation that is a primitive
4261 operation of an RACW stub type (these primitives are only executed
4262 through dispatching, never through static calls).
4263 (Collect_Interps): When only one interpretation has been found, set N's
4264 Entity and Etype to that interpretation, otherwise Entity and Etype may
4265 still refer to an interpretation that was ignored by Add_One_Interp,
4266 in which case would end up with being marked as not overloaded but with
4267 an Entity attribute not pointing to its (unique) correct interpretation.
4269 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4272 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4282 (Print_Itype): Do not modify the sloc of the component type of a
4283 (packed) array itype, because it is an unrelated type whose source
4284 location is independent of the point of creation of the itype itself.
4286 2008-05-20 Thomas Quinot <quinot@adacore.com>
4288 * uintp.adb, urealp.adb: Replace calls to Increment_Last + Set with

4323 2008-05-20 Arnaud Charlet <charlet@adacore.com>

4326 equivalent representation, but has the advantage of allowing
4327 compilation of this file under 64 bits platforms.

8526 subprogram body that acts as its own spec may not have a non-private
8527 WITH clause on a private sibling.
8528 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8529 child unit is a renaming, create an implicit with_clause on that
8530 parent, and not on the unit it renames, to prevent visibility errors

8595 formal of a generic subprogram. find candidate interpretations by
8596 scanning the list of generic formal declarations.:
8597 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8598 type from a limited_with_clause, and the full view is available, use it
8599 for subsequent semantic checks.

8627 Gary Dismukes <dismukes@adacore.com>
8629 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8630 requeue statement is dispatching. Do not emit an error when the name is
8631 not an entry and the context is a dispatching select. Add code to
8632 perform subtype conformance between the formals of the current entry
8633 and those of the target interface primitive.
8634 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8635 Timed_Entry_Call): Analyze the triggering statement as the first step of
8636 the processing. If this is a dispatching select, postpone the analysis
8637 of all select statements until the Expander transforms the select. This
8638 approach avoids generating duplicate identifiers after the Expander has
8639 replicated some of the select statements. In case the Expander is
8640 disabled, perform regular analysis.
8641 (Check_Triggering_Statement): New routine.
8642 (Analyze_Requeue): Exclude any interpretations that are not entries when
8643 checking overloaded names in a requeue. Also test type conformance for
8644 matching interpretations rather than requiring subtype conformance at
8645 that point to conform with the RM's resolution rule for requeues.

8649 * sem_disp.adb (Check_Dispatching_Call): If an actual in a call to an
8650 inherited operation is a defaulted tag-indeterminate call, and there is
8651 a statically tagged actual, use the static tag as a controlling actual
8652 for the defaulted actual.
8654 2007-12-13 Geert Bosch <bosch@adacore.com>
8656 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8681 latest Ada 2005 rules about renaming and 'Access of
8682 discriminant-dependent components.

9239 multiple inherited interfaces info. This information cannot be stored
9240 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9257 additional management on these nodes in Expand_Interface_Actuals.
9259 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9260 that handles use of 'Access and 'Unchecked_Access applied to

9306 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9307 used by VxWorks targets to have access to task-specific data and be
9308 able to extract the stack boundaries for stack checking.

9352 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9353 association for an access component, add an association with null as
9354 the expression. Remove testing for array subtypes and the setting in
9355 that case of Ctyp to the array component type, which prevented proper
9356 inclusion of an association for null-initialized arrays. Collapse
9357 condition that tests for array subtypes into just a test of
9358 Is_Partially_Initialized_Type (which already covers arrays anyway).

9375 * sem_ch4.adb: Minor code and comment reformatting.
9376 (Analyze_Allocator): When the designated type of an unconstrained
9377 allocator is a record with unknown discriminants or an array with

9544 Add a section on leap seconds control along with two entities used to
9545 enable and disable leap seconds support. The array Leap_Second_Times is
9546 now constant and contains hard time values pre-generated. Remove

9608 Eric Botcazou <ebotcazou@adacore.com>
9611 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9612 indirection added to the HT_Link component of the TSD. This is required
9613 to statically allocate the TSD.
9616 Minor reordering of the declarations in the private part. Required to
9617 add a level of indirection to the contents of the TSD component HT_Link.
9618 This is required to statically allocate the TSD.
9620 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9621 Is_Statically_Allocated set from constant objects.
9622 Do not make exported constants created by the compiler volatile.
9623 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9626 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9627 before returning them.

9630 public part of the package.
9631 (Make_DT): Move HT_Link component out of the TSD record. For this
9632 purpose Make_DT now declares a separate object that stores the
9633 HT_Link value, and initializes the TSD component with the address
9634 of this new object. The addition of this level of indirection is
9635 required to statically allocate the TSD because the TSD cannot
9636 have variable components.
9637 (Expand_Interface_Conversion): Improve the expanded code.
9638 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9640 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9641 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9642 if we are building static dispatch tables then we must not generate
9643 extra code to register the primitive because the dispatch table will
9644 be built at the end of the library package; otherwise we notify that
9645 we cannot build the static dispatch table.
9647 2007-09-26 Robert Dewar <dewar@adacore.com>
9649 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9664 for thunks associated with interface types.
9666 * einfo.ads: Improve documentatation of Is_Internal
9667 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9668 associated with interface types.
9669 Extensive comment fixes regarding flags that appear in all entities. The
9670 documentation is now consistent for all such flags (there were a number
9671 of errors in the documentation in this regard).
9673 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9675 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9676 of these procedures are passed a function call that already has
9677 build-in-place actuals (testing new flag
9678 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9679 the case where processing continues.
9680 (Expand_Call): If the call is generated from a thunk body then we
9681 propagate the extra actuals associated with the accessibility
9682 level of the access type actuals.
9684 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9685 of each extra formal of a protected operation to reference the
9686 corresponding extra formal of the subprogram denoted by the
9687 operation's Protected_Body_Subprogram.
9689 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9690 N_Function_Call nodes.
9692 2007-09-26 Robert Dewar <dewar@adacore.com>
9694 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9696 * debug.adb: Add d.s flag.

9700 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9701 debug variable so that it won't be initialized when pragma
9702 Initialize_Scalars is in effect.
9704 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9706 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9707 initialization of a full view. This is moved to

9710 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9711 preelaborable initialization of a full view in entity loop.
9712 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9713 its child units are use-visible only if they are visible child units.
9715 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9716 whether an expression can be used within a type declaration that
9717 requires preelaborable init.
9718 (Check_Components): Replace inline code that does partial checking for
9719 preelaborable default expressions with call to
9720 Is_Preelaborable_Expression.
9721 (Has_Preelaborable_Initialization): In the case of a generic actual
9722 subtype, (that is, Is_Generic_Actual is True), return the result of
9723 applying Has_Preelaborable_Initialization to the generic actual's base
9726 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9728 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9729 call to Jan_1_Day _Of_Week to optimize its performance.
9730 (Is_Leap): Move the routine to the scope of Week_In_Year.
9731 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9732 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9733 avoids calling Time_Of and Split, thus making it more efficent.
9734 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9736 * g-calend.ads (Week_In_Year): Change comment to reflect new
9739 2007-09-26 Emmanuel Briot <briot@adacore.com>
9741 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9742 Command_Line): New types
9743 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9744 support for defining how switches can be grouped on a command line (as
9745 is the case for -gnatw... for GNAT), and how simple switches can be
9746 used as aliases for more complex switches (-gnatwa is same as
9748 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9749 (Start, Current_*): New subprograms
9750 Added support for parsing an array of strings in addition to the real
9752 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9753 be moved from the body to the private part of the spec.
9754 (*): All subprograms now have an extra parameter with default value to
9755 specify which parser should be used. For backward compatibility, it
9756 defaults to parsing the command line of the application. They were also
9757 modified to properly handle cases where each of the argument does not
9758 start at index 1 (which is always true for Ada.Command_Line, but not
9759 when processing any Argument_List).
9760 (Free): New subprogram
9761 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9762 Argument): New subprograms
9763 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9764 special characters like ':', '=',... are now handled in a single place,
9765 which makes the code more extensible eventually.
9766 (Getopt, Full_Switch): When the switch was returned as part of the
9767 special character '*', make sure it is prepended by the switch character
9768 ('-' in general), so that the application knows whether "foo" or "-foo"
9769 was specified on the command line.
9771 2007-09-26 Florian Villoing <villoing@adacore.com>
9773 * g-dirope.adb (Remove_Dir): In case we are removing directories
9774 recursively, make sure that if an exception is raised during the
9775 processing, the current working directory is reset to its initial
9776 value before propagating the exception.
9778 2007-09-26 Vincent Celier <celier@adacore.com>
9780 * gnatbind.adb: If there are several ALI files specified and there is
9781 a main program to bind, the first ALI is expected to contain the main
9782 subprogram and the names of the binder generated files will be derived
9783 from the first ALI file name.
9784 (Gnatbind): Fix insertion character in invocation of Error_Msg
9786 2007-09-26 Vincent Celier <celier@adacore.com>
9788 * gnatcmd.adb (Check_Files): Do not include sources that have been
9789 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9791 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9793 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9794 information about each of its index types, following the type
9795 reference for its component type.
9797 2007-09-26 Vincent Celier <celier@adacore.com>
9799 * make.adb: (Kill): New procedure (__gnat_kill imported)

9806 sources, so that the correct paths will be found.
9808 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9810 2007-09-26 Vincent Celier <celier@adacore.com>
9812 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9814 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9815 Replace components Compiler_Min_Options and Binder_Min_Options with
9816 Compiler_Required_Switches and Binder_Required_Switches in record
9818 Remove components Default_Language and Config in Project_Tree_Data,
9821 * prj-attr.adb: New attributes Required_Switches (<language>) in
9822 packages Compiler and Binder.
9824 * prj-nmsc.adb: Major rewrite of the processing of configuration
9825 attributes for gprbuild. No impact on GNAT tools.
9827 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

9833 (Process): Implementation now uses the two new procedures
9835 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9836 from the project config, not the tree config that no longer exists.

9859 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9861 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9862 ancestor of the derived type, the operations are inherited from the
9863 primary dispatch table of the parent.
9864 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9865 when the context is an explicit type conversion.
9867 2007-09-26 Ed Schonberg <schonberg@adacore.com>

9912 no sources, but is an extending project.
9914 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9916 * trans.c: Fix misplaced #define.

10169 body for 'Output when the type is abstract (only the creation of the
10170 body for 'Input is excluded when the type is abstract).

10172 statement, so that False will be returned for TTS_Stream_Input if the
10173 associated tagged type is an abstract extension. Add comments for

10176 variable, insert init proc call only after the shared variable
10177 procedures have been processed, because the IP call needs to undergo

10191 type, retrieve its value from the aggregate itself, where it must have
10194 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10195 to remove other spurious ambiguities on arithmetic operations involving
10196 literals and addresses, on systems where Address is a visible integer
10197 type, when the operator is called in functional notation.
10198 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10199 is legal when the types match, even if the operation is currently

10317 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10319 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10324 (Write_Entity_Flags): Write the status of flag Is_Raised.
10325 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10326 spurious ambiguities when integer literals appear in the context of an
10327 address type that is a visible integer type.
10329 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10330 exceptions never being raised.
10331 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10347 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10348 library-level package renaming, pass the declaration associated with
10349 the renaming's special debug variable to Qualify_Entity_Names to ensure
10350 that its encoded name is properly qualified.
10352 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10353 occurring in the list of entities to qualify, and do not attempt to
10354 traverse an entity list in that case. Variables associated with
10355 ` library-level package renamings can now occur in the table.
10357 * exp_dbug.ads: Revise documentation of the encoding for renaming
10360 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

10363 access type points to an unconstrained array.
10365 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10367 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10370 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10371 simple redundant qualifications. The check is performed whenever the

10379 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10380 concatenations of string literals into a single literal, in order to
10381 avoid very deep recursion in the front end, which was causing stack
10384 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10385 string, and the right operand is a string literal (the case of "" &
10386 "..."), optimize by avoiding copying the right operand -- just use the
10387 value of the right operand directly.
10389 * stringt.adb (Store_String_Chars): Optimize by growing the
10390 String_Chars table all at once, rather than appending characters one by
10392 (Write_String_Table_Entry): If the string to be printed is very long,
10393 just print the first few characters, followed by the length. Otherwise,
10394 doing "pn(n)" in the debugger can take an extremely long time.
10396 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10397 Store_String_Char with Store_String_Chars.

10410 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10411 clauses of subunits, ignore limited_with_clauses that are illegal and
10412 have not been fully analyzed.
10414 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10416 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10417 flag, for effiency. It is called when analyzing arithmetic operators
10418 and also for actuals in calls that are universal_integers. The flag is
10419 set for the predefined type address, and for any type or subtype
10422 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10423 Universal_Integer, when the formal is a descendent of address and the
10424 call appears in user code.
10425 (Analyze_Selected_Component): if the prefix is a private extension, the
10426 tag component is visible.

10489 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10491 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10492 associated with Standard_Debug_Renaming_Type, to be used as the type of
10493 the special variables whose names provide debugger encodings for
10494 renaming declarations.
10496 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10497 (Set_Debug_Renaming_Link): Change to set Node25.

10504 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10505 and literal with creation of a variable of type
10506 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10507 and the entity of the renaming declaration.
10508 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10509 part of the name of a variable that has a Debug_Renaming_Link.
10511 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10512 special type to be associated with variables that provide debugger

10516 Ed Schonberg <schonberg@adacore.com>
10517 Javier Miranda <miranda@adacore.com>
10519 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10520 ancestor part given by an aggregate to test for an unchecked conversion,
10521 since this can occur in some cases when the ancestor part is a function
10522 call, and we don't want to fall into the recursive call to this
10523 procedure in that case.
10525 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10526 stream attributes on limited types to account for user-specified
10527 attributes as well as whether Input (resp. Output) becomes available
10528 due to Read (resp. Write) being available for the type. Change Boolean
10529 variable to the more accurate name
10530 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10531 double-"not" predicate at beginning of return statement to more
10532 understandable form.
10534 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10535 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10536 in a block statement and use that as the first statement of the
10537 expanded return rather than incorrectly using the handled sequence as
10538 the first statement.
10540 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10541 operation, generate an explicit freeze node for it rather than
10542 generating extra formals, to ensure that gigi has the proper order of
10543 elaboration for anonymous subtypes in the signature of the subprograms.
10544 (Build_In_Place_Formal): Move assertion to beginning of loop.
10545 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10548 applied to a function call (occurs for some cases of 'Input).
10550 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10551 2005, generate an extended return statement enclosing the result object
10554 * freeze.adb (Freeze_Record_Type): Extend the current management of
10555 components that are access type with an allocator as default value: add
10556 missing support to the use of qualified expressions of the
10557 allocator (which also cause freezing of the designated type!)
10558 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10559 dispatching operation, since extra formals may be needed by calls to
10560 build-in-place functions (such as stream 'Input).
10562 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10563 formals for 'Constrained and accessibility level in the case of a
10564 predefined dispatching operation.
10566 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10567 point, no need to find the parent node.
10569 2007-08-16 Javier Miranda <miranda@adacore.com>
10571 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10572 and entry barriers.
10574 2007-08-16 Javier Miranda <miranda@adacore.com>
10576 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10577 is not really required and can introduce regression with the debugger.
10578 The original problem is fixed with the patch written for checks.adb.
10580 2007-08-16 Thomas Quinot <quinot@adacore.com>
10582 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10589 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10590 Including_Non_Switch set to False.
10592 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10593 parameter Including_Non_Switch, defaulted to True. When
10594 Including_Non_Switch is False, options that are not switches and
10595 appear as relative path are not converted to absolute paths.
10597 2007-08-16 Nicolas Roche <roche@adacore.com>
10599 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10610 from the immediate ancestor of Main_Unit_Entity.
10611 (Install_Limited_Withed_Unit): Do not install the limited view of
10612 package P if P is reachable through an ancestor chain from package C
10613 and C also has a with clause for P in its body.

10615 (Has_With_Clause): New routine.
10617 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10619 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10620 generic for an enclosing instance is a global reference, even though
10621 its scope is the enclosing instance.
10623 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10624 Javier Miranda <miranda@adacore.com>
10626 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10627 initialize a limited object.

10632 2007-08-16 Robert Dewar <dewar@adacore.com>
10634 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10637 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10639 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10640 implements an operation inherited from a progenitor interface, verify
10641 that they are subtype-conformant.
10643 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10644 Bob Duff <duff@adacore.com>
10645 Nicolas Setton <setton@adacore.com>
10647 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10648 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10649 the statement which is being resolved comes from a predefined library
10650 unit, all non-predefined library interpretations are skipped.
10651 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10652 but the "&" is user defined, give an error, because the folding would
10655 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10656 the parser has folded a long sequence of concatenations of string
10659 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10660 and "JMP_BUF" variables as artificial.
10661 (N_String_Literal): Do not use alloca for very long string literals. Use
10662 xmalloc/free instead. Otherwise the stack might overflow.
10664 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the

10709 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10710 Suppress unmodified in-out parameter warning in some cases
10711 This patch is a also fairly significant change to the way suppressible
10712 checks are handled.
10714 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10715 needed for access to concurrent record types generated by the expander.
10716 (Generate_Range_Check): When generating a temporary to capture the
10717 value of a conversion that requires a range check, set the type of the
10718 temporary before rewriting the node, so that the type is always
10719 properly placed for back-end use.
10720 (Apply_Float_Conversion_Check): Handle case where the conversion is
10722 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10739 parameters when deciding whether to apply a run-time accessibility
10741 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10742 aggregate code before allocator, and ahead of declaration for
10743 temporary, to prevent access before elaboration when the allocator is
10744 an actual for an access parameter.
10745 (Expand_N_Type_Conversion): On an access type conversion involving an
10746 access parameter, do not apply an accessibility check when the
10747 operand's original node was an attribute other than 'Access. We now
10748 create access conversions for the expansion of 'Unchecked_Access and
10749 'Unrestricted_Access in certain cases and clearly accessibility should
10750 not be checked for those.
10752 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10753 includes a type conversion of a packed component that has been expanded,
10754 recover the original expression for the object, and use this expression
10755 in the post-call assignment statement, so that the assignment is made
10756 to the object and not to a back-end temporary.
10757 (Freeze_Subprogram): In case of primitives of tagged types not defined
10758 at the library level force generation of code to register the primitive
10759 in the dispatch table. In addition some code reorganization has been
10760 done to leave the implementation clear.
10761 (Expand_Call): When expanding an inherited implicit conversion,
10762 preserve the type of the inherited function after the intrinsic
10763 operation has been expanded.
10765 * exp_ch2.ads, exp_ch2.adb
10766 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10767 of an entry formal appearing in an assignment statement does not assign
10769 (Expand_Current_Value): Instead of calling a routine to determine
10770 whether the prefix of an attribute reference should be optimized or
10771 not, prevent the optimization of such prefixes all together.
10773 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10774 component whose prefix is known to be of an access type is an implicit
10775 dereference and does not assign to the prefix.
10777 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10778 Robert Dewar <dewar@adacore.com>
10780 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10781 itype is visited, make an entry into table to link associated node and
10783 Add comments and correct harmless error in Build_NCT_Hash_Tables
10784 (Array_Aggr_Subtype): Associate each itype created for an index type to
10785 the corresponding range construct, and not to the aggregate itself. to
10786 maintain a one-to-one correspondence between itype and its associated
10787 node, to prevent errors when complex expression is copied.
10788 Fix mishandling of multiple levels of parens
10790 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10791 treatment of limited views uniform for all visible declarations in a
10792 limited_withed package.
10793 (New_Copy_Tree): If hash table is being used and itype is visited,
10794 make an entry into table to link associated node and new itype.
10795 (Resolve_Record_Aggregate): Do not add an others box association for a
10796 discriminated record component that has only discriminants, when there
10797 is a box association for the component itself.

10844 Warn on duplicate pragma Preelaborable_Initialialization
10846 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10847 generation of a freezing node to ensure proper management of null
10848 excluding access types in the backend.
10849 (Create_Extra_Formals): Test base type of the formal when checking for
10850 the need to add an extra accessibility-level formal. Pass the entity E
10851 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10852 originally being done in a couple of cases), to ensure that the
10853 Extra_Formals list gets set on the entity E when the first entity is
10855 (Conforming_Types): Add missing calls to Base_Type to the code that
10856 handles anonymous access types. This is required to handle the
10857 general case because Process_Formals builds internal subtype entities
10858 to handle null-excluding access types.
10859 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10860 functions that need it, even when not marked Requires_Overriding.
10861 Improve warnings for in out parameters
10862 (Analyze_Function_Return): Warn for disallowed null return
10863 Warn on return from procedure with unset out parameter
10864 Ensure consistent use of # in error messages
10865 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10866 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10867 the implicit conversion of the expression done for anonymous access
10868 types. This is required to generate the code of the null excluding
10869 check (if required).
10871 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10872 A formal parameter is never publicly referenceable outside of its body.
10873 (Check_References): For an unreferenced formal parameter in an accept
10874 statement, use the same warning circuitry as for subprogram formal
10876 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10877 Output_Unreferenced_Messages, containing the part of that routine that
10878 is now reused for entry formals as described above.
10879 (Goto_Spec_Entity): New function
10880 (Check_References): Do not give IN OUT warning for dispatching operation
10881 Improve warnings for in out parameters

10888 Javier Miranda <miranda@adacore.com>
10889 Gary Dismukes <dismukes@adacore.com>
10891 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10892 (Expand_N_Attribute_Reference): Further unify the handling of the
10893 three forms of access attributes, using common code now for all three
10894 cases. Add a test for the case of applying an access attribute to
10895 an explicit dereference when the context is an access-to-interface
10896 type. In that case we need to apply the conversion to the prefix
10897 of the explicit dereference rather than the prefix of the attribute.
10898 (Attribute_Version, UET_Address): Set entity as internal to ensure
10899 proper dg output of implicit importation.
10900 (Expand_Access_To_Type): Removed.
10901 (Expand_N_Attribute_Reference): Merge the code from the three cases
10902 of access attributes, since the processing is largely identical for
10903 these cases. The substantive fix here is to process the case of a
10904 type name prefix (current instance case) before handling the case
10905 of interface prefixes.

10910 Robert Dewar <dewar@adacore.com>
10912 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10913 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10914 type that is an anonymous access to controlled object, establish
10915 an associated finalization chain to avoid corrupting the global
10916 finalization list when a dynamically allocated object designated
10917 by such a component is deallocated.
10918 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10919 functions that need it, even when not marked Requires_Overriding.
10920 (Initialize_Tag): Replace call to has_discriminants by call to
10921 Is_Variable_Size_Record in the circuitry that handles the
10922 initialization of secondary tags.
10923 (Is_Variable_Size_Record): New implementation.
10924 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10925 Suppress_Initialization pragma for a derived type.
10926 (Is_Variable_Size_Record): New subprogram.
10927 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10928 initial version of this routine and also fixes problems causing
10929 incomplete initialization of the table of interfaces.
10930 (Build_Init_Procedure): Improve the generation of code to initialize the
10931 the tag components of secondary dispatch tables.
10932 (Init_Secondary_Tags): New implementation that simplifies the previous
10933 version of this routine.
10934 (Make_DT): Add parameter to indicate when type has been frozen by an
10935 object declaration, for diagnostic purposes.
10936 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10937 diagnose attemps to freeze a subprogram when some untagged type of its
10938 profile is a private type whose full view has not been analyzed yet.
10939 (Freeze_Array_Type): Generate init proc for packed array if either
10940 Initialize or Normalize_Scalars is set.
10941 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10942 constructing the new profile, copy the null_exclusion indicator for each
10943 parameter, to ensure full conformance of the new body with the spec.
10945 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10946 Create wrappers for constructor functions that need it, even when not
10947 marked Requires_Overriding.
10948 (Covers): Handle properly designated types of anonymous access types,
10949 whose non-limited views are themselves incomplete types.
10950 (Add_Entry): Use an entity to store the abstract operation which hides
10952 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10953 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10954 initialization aggregate.
10955 (Function_Interp_May_Be_Hidden): Rename to
10956 Function_Interp_Has_Abstract_Op.
10957 (Has_Compatible_Type): Remove machinery that skips interpretations if
10958 they are labeled as potentially hidden by an abstract operator.
10959 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10960 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10961 (Write_Overloads): Output the abstract operator if present.
10962 (Add_Entry): Before inserting a new entry into the interpretation table
10963 for a node, determine whether the entry will be disabled by an abstract

10966 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10968 (Function_Interp_May_Be_Hidden): New routine.
10969 (Has_Compatible_Type): Do not consider interpretations hidden by
10970 abstract operators when trying to determine whether two types are
10972 (Has_Hidden_Interp): New routine.
10973 (Set_May_Be_Hidden_Interp): New routine.
10974 (Write_Overloads): Write the status of flag May_Be_Hidden.

10979 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10980 types declared in the declarative part of a nested package body or in
10981 the proper body of a stub.
10982 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10983 of the same dispatch table slot to renamed primitives.
10984 (Make_Select_Specific_Data_Table): Handle private types.
10985 (Tagged_Kind): Handle private types.
10986 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10987 output of implicit importation and exportation.
10988 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10989 first formal of the thunk is always associated with the controlling
10990 type. In addition perform the following code cleanup: remove formal
10991 Thunk_Alias which is no longer required, cleanup evaluation of the
10992 the controlling type, and update the documentation.
10993 Replace occurrence of Default_Prim_Op_Count by
10994 Max_Predef_Prims. Addition of compile-time check to verify
10995 that the value of Max_Predef_Prims is correct.
10996 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10997 (Make_DT): Add parameter to indicate when type has been frozen by an
10998 object declaration, for diagnostic purposes.
10999 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11000 construction of statically allocated dispatch tables.
11001 (Make_DT): In case of library-level tagged types export the declaration
11002 of the primary tag. Remove generation of tags (now done by Make_Tags).
11003 Additional modifications to handle non-static generation of dispatch
11004 tables. Take care of building tables for asynchronous interface types
11005 (Make_Tags): New subprogram that generates the entities associated with
11006 the primary and secondary tags of Typ and fills the contents of Access_
11007 Disp_Table. In case of library-level tagged types imports the forward
11008 declaration of the primary tag that will be declared later by Make_DT.
11009 (Expand_Interface_Conversion): In case of access types to interfaces
11010 replace an itype declaration by an explicit type declaration to avoid
11011 problems associated with the scope of such itype in transient blocks.
11013 2007-08-14 Robert Dewar <dewar@adacore.com>
11014 Ed Schonberg <schonberg@adacore.com>
11015 Javier Miranda <miranda@adacore.com>
11017 * exp_util.ads, exp_util.adb:
11018 This patch replaces a number of occurrences of explicit tests for N_Null
11019 with calls to Known_Null. This improves tracking of null values, since
11020 Known_Null also catches null constants, and variables currently known to
11021 be null, so we get better tracking.
11022 (Ensure_Defined): create an itype reference only in the scope of the
11024 (Side_Effect_Free): A selected component of an access type that
11025 denotes a component with a rep clause must be treated as not
11026 side-effect free, because if it is part of a linked structure its
11027 value may be affected by a renaming.
11028 (Expand_Subtype_From_Expr): For limited objects initialized with build
11029 in place function calls, do nothing; otherwise we prematurely introduce
11030 an N_Reference node in the expression initializing the object, which
11031 breaks the circuitry that detects and adds the additional arguments to
11032 the called function. Bug found working in the new patch for statically
11033 allocated dispatch tables.
11034 (Is_Library_Level_Tagged_Type): New subprogram.
11035 (Remove_Side_Effects): If the expression of an elementary type is an
11036 operator treat as a function call.
11037 (Make_Literal_Range): If the index type of the array is not integer, use
11038 attributes properly to compute the constraint on the resulting aggregate
11041 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11042 class-wide type whose base type is an incomplete private type, leave
11043 class-wide type unfrozen so that freeze nodes can be generated
11044 properly at a later point.
11045 (Freeze_Entity, array case): Handle case of pragma Pack and component
11046 size attributre clause for same array.

11103 attribute Body in package Naming. Do not replace a source/unit in the
11104 same project when the order of the source dirs are known. Detect
11105 duplicate sources/units in the same project when the order of the
11106 source dirs are not known.
11107 (Check_Ada_Name): Allow all identifiers that are not reserved words
11109 Major update of the Project Manager and of the project aware tools,

11113 directory of non extending project to nil.
11114 Change type of path name variables to be Path_Name_Type

11721 controlling formal is not an in_parameter, reject the actual if it is
11722 an access_to_constant type.
11723 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11724 type, the candidate operations are found in the scope of declaration of
11725 the type, because the type has no primitive subprograms.
11726 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11727 a private extension, only examine visible components before trying to
11728 analyze as a prefixed call.
11729 Change Entity_List to Type_To_Use, for better readability.

11742 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11743 purpose of enforcing E.2.2(8) only if it is not available at any place.
11744 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11745 when checking the legality of an extension aggregate in a preelaborable
11746 package. Treat the literal null as a valid default expression in a
11747 component declaration for a type with preelaborable initialization.
11748 A limited interface is a legal progenitor for the designated type of a
11749 remote access to class-wide type.

11782 (Resolve_Actuals): When verifying that an access to class-wide object
11783 is an actual for a controlling formal, ignore anonymous access to
11784 subprograms whose return type is an access to class_wide type.
11785 (Resolve_Slice): If the prefix of the slice is a selected component
11786 whose type depends on discriminants, build its actual subtype before

11789 to prevent anomalies between private and public views.

11811 elabration statements, register the package with the name server

13003 is its corresponding record, as can be the case when the primitive
13004 operation is declared outside of the body of the type.
13005 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13006 perform homonym traversal, looking for class-wide operation matches
13007 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13008 access parameters are now restricted to anonymous access types.
13009 (Mark_Allocator): An allocator with a discriminant association parent is
13011 (Try_One_Prefix_Interpretation): If the type of the object is
13012 incomplete, as can be happen when it is a limited view obtained through
13013 a limited_with_clause, the selected component is not part of a prefixed
13015 (Complete_Object_Operation): Diagnose properly an object that is not
13016 aliased when the corresponding controlling formal is an access
13018 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13019 ambiguous calls in prefixed notation, where two primitives differ only
13020 in that the controlling argument of one is an access parameter.
13022 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13023 whether a function that returns an unconstrained type can be inlined.
13024 (Process_Formals): Diagnose properly the illegal use of an incomplete
13025 type in the profile of an access_to_subprogram declaration.
13026 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13027 operations are attached to the corresponding record.
13028 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13029 When processing a primitive of a concurrent type which implements an
13030 interface change the type of all controlling formals to that of the
13031 corresponding record type.
13032 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13033 to determine the tagged type to which a primitive belongs.
13034 (Check_Conventions): Capture condition to ignore a primitive operation
13035 (which is shared between the loop in Check_Conventions and the one in
13036 Check_Convention) in a new local function Skip_Check.
13037 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13038 confusion with Check_Conventions' own Prim_Op local variable.
13039 (Create_Extra_Formals): Test for a tagged result type rather than a
13040 controlling result when determining whether to add a BIP_Alloc_Form
13041 formal and a BIP_Final_List formal to the function.
13042 (Check_Conformance); For parameters that are anonymous access types,
13043 subtype conformance requires that the not null and the constant
13044 indicators must match
13045 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13046 to retrieve the appropriate type when processing a concurrent type
13047 declared within a generic. Minor comment reformatting. Change invocation
13048 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13050 (Analyze_Subprogram_Body): If the return type of a function is an
13051 anonymous access to the limited view of a class-wide type, and the
13052 non-limited view of the type is available, update the type of the
13053 function so that code can be generated.
13054 (Process_Formals): In case of access-subtype itype whose designated
13055 type is also an itype (situation that happens now with access to
13056 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13057 attribute to avoid backend problems.
13058 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13059 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13060 anonymous types' designated types are same before testing
13061 Subtypes_Statically_Match.
13062 (Create_Extra_Formals): Test for a named access parameter that is a
13063 controlling formal as an additional condition for adding an
13064 accessibility level formal. This can occur in the subp type created for
13065 dispatching calls in Expand_Dispatching_Call, and allows calling
13066 Create_Extra_Formals from that procedure rather than special-casing the
13067 extra formals there.
13068 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13069 when the function has a controlling result.
13070 (Check_Returns): Add much more knowledge of the optimization of local
13071 raise statements to gotos, to retain proper warnings in this case.
13072 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13073 nodes when looking for last statement.
13075 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13076 class-wide types visible through limited with clauses.
13077 (Add_One_Interp): If the operands are anonymous access types, the
13078 predefined operator on universal_access is immediately visibles
13079 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13080 other anonymous access types.
13081 (Disambiguate): Take into account CIL convention.
13082 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13084 2007-06-06 Robert Dewar <dewar@adacore.com>
13086 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13087 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13088 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13089 Fix lower bound of tables.
13092 * nlists.adb: Ditto.
13093 (Prev_Node, Next_Node): Change index type to Int so that it properly
13094 covers the range First_Node_Id - 1 up.
13096 2007-06-06 Javier Miranda <miranda@adacore.com>
13097 Ed Schonberg <schonberg@adacore.com>
13098 Bob Duff <duff@adacore.com>
13099 Hristian Kirtchev <kirtchev@adacore.com>
13101 * exp_aggr.ads, exp_aggr.adb:
13102 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13103 in extension aggregates.
13104 (Flatten): Other conditions being met, an aggregate is static if the
13105 low bound given by component associations is different from the low
13106 bound of the base index type.
13107 (Packed_Array_Aggregate_Handled): If the component type is itself a
13108 packed array or record, the front-end must expand into assignments.
13109 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13110 Init_Pr, instead of Ancestor_Is_Expression.
13111 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13112 coextension chain root, either generate a list controller or use the
13113 already existing one.
13114 (Static_Array_Aggregate): New procedure to construct a positional
13115 aggregate that can be handled by the backend, when all bounds and
13116 components are compile-time known constants.
13117 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13118 types covering interface types into assignments.
13119 (Replace_Type): move to Build_Record_Aggr_Code.
13120 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13121 interface type, convert to the definite type of the aggregate itself,
13122 so that needed components are visible.
13123 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13124 components and the context is an extended return statement do not
13125 create a transient block for it, to prevent premature finalization
13126 before the return is executed.
13127 (Gen_Assign): Do not generate a call to deep adjust routine if the
13128 component type is itself an array of controlled (sub)-components
13129 initialized with an inner aggregate.
13130 (Component_Check): New name for Static_Check. This name is now more
13131 appropriate, and documentation is added which was missing.
13132 (Component_Check): Add test for bit aligned component value
13133 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13134 Tagged_Comps, name is more appropriate given added function below.
13135 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13137 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13138 Javier Miranda <miranda@adacore.com>
13139 Robert Dewar <dewar@adacore.com>
13141 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13142 Terminated: Add unchecked type conversion from System.Address to
13143 System.Tasking.Task_Id when calling the predefined primitive
13145 Disable new Ada 05 accessibility check for JVM.NET targets, which
13146 cannot be implemented in a practical way.
13147 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13148 the sources always references the tag of the actual object. Therefore,
13149 if 'Tag is applied in the sources to class-wide interface objects we
13150 generate code that displaces "this" to reference the base of the object.
13151 (Expand_N_Attribute_Reference, case Size): Return specified size if
13152 known to front end.
13153 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13154 has code that displaces the pointer of the object to manage interface
13155 types. However this code must not be executed when the prefix is a
13156 subprogram. This bug caused the wrong expansion of the internally
13157 generated assignment that fills the dispatch table when the primitive
13158 is a function returning a class-wide interface type.
13159 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13160 Set_Attribute_Name for Name_Unaligned_Valid.
13162 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13163 Gary Dismukes <dismukes@adacore.com>
13165 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13166 If the initialization is the equivalent aggregate of the initialization
13167 procedure of the type, do not remove it.
13168 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13169 initialized to null from having their expression reset to empty and
13170 note this exception in the comment.
13172 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13173 Robert Dewar <dewar@adacore.com>
13174 Ed Schonberg <schonberg@adacore.com>
13175 Gary Dismukes <dismukes@adacore.com>
13177 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13178 Add "with" and "use" clauses for Sem_Attr.
13179 (Expand_Current_Value): Do not replace occurences of attribute
13180 references where the prefix must be a simple name.
13182 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13183 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13184 Attribute_Requires_Simple_Name_Prefix.
13185 (Name_Modifies_Prefix): Body of new function.
13186 (Requires_Simple_Name_Prefix): Body of new function.
13187 (Resolve_Attribute, case Access): Improve error message for case of
13188 mismatched conventions.
13189 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13191 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13192 constrained subtype for a nominal unconstrained type, use its base type
13193 to check for conformance with the context.
13194 (Resolve_Attribute): Remove test of the access type being associated
13195 with a return statement from condition for performing accessibility
13196 checks on access attributes, since this case is now captured by
13197 Is_Local_Anonymous_Access.
13198 (Analyze_Access_Attribute): Set Address_Taken on entity
13199 (Analyze_Attribute, case Address): Set Address_Taken on entity
13200 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13201 validating an access attribute whose prefix is a current instance.
13202 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13203 applied to dispatching operations, if freezing is required then we set
13204 the attribute Has_Delayed_Freeze in the prefix's entity.
13205 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13206 current scope if access of local subprogram taken
13207 (Analyze_Access_Attribute): Check legality of self-reference even if the
13208 expression comes from source, as when a single component association in
13209 an aggregate has a box association.
13210 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13211 the prefix if it is a protected operation and the attribute is
13212 Unrestricted_Access.
13213 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13214 reference to the base type of the context, to force a constraint check
13215 when the context is an access subtype with an explicit constraint.
13216 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13217 node is rewritten as an interface conversion. leave unanalyzed after
13218 resolution, to ensure that type checking against the context will take

13222 Javier Miranda <miranda@adacore.com>
13223 Robert Dewar <dewar@adacore.com>
13225 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13226 wrapper when the full view of the controlling type of an inherited
13227 function that dispatches on result implements interfaces.
13228 (Expand_N_Object_Declaration): In cases where the type of the
13229 declaration is anonymous access, create finalization list for it.
13230 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13231 if the object has no explicit initialization, to match description of
13232 functionality of pragam Persistent_BSS.
13233 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13234 new function to build static aggregates, to replace initialization call
13235 when static initialization is desired.
13236 (Freeze_Type): Generate a list controller for an access type whenever
13237 its designated type has controlled anonymous access discriminants.
13238 (Build_Equivalent_Aggregate): New procedure to compute a static
13239 aggregate to be used as default initialization for composite types,
13240 instead of a generating a call to the initialization procedure for the
13242 (Build_Initialization_Call): When available, replace a call to the
13243 initialization procedure with a copy of the equivalent static aggregate
13245 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13246 declarations for objects of a class-wide interface type, rather than
13247 just identifiers, to prevent visibility problems.
13248 (Expand_N_Object_Declaration): When expanding the declaration for an
13249 object of a class-wide interface type, preserve the homonym chain of
13250 the original entity before exchanging it with that of the generated
13251 renaming declaration.
13252 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13253 active, because there is no way to handle the exception.
13254 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13255 to do a minimum decoration of the Access_Disp_Table list.
13256 (Expand_Record_Controller): Avoid the addition of the controller between
13257 the component containing the tag of a secondary dispatch table and its
13258 adjacent component that stores the offset to the base of the object.
13259 This latter component is only generated when the parent type has
13260 discriminants ---documented in Add_Interface_Tag_Components).
13261 (Apply_Array_Size_Check): Removed, no longer needed.
13262 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13263 components, create a Master_Entity for it only if it contains tasks.
13264 (Build_Init_Procedure): Suppress the tag assignment compiling under
13266 (Freeze_Record_Type): Remove code associated with creation of dispatch
13268 (Init_Secondary_Tags): Update type of actuals when generating calls to
13269 Ada.Tags.Set_Offset_To_Top
13270 (Stream_Operation_OK): Disable use of streams compiling under no
13272 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13273 if Has_Init_Expression set.
13274 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13275 Register_Primitive, which provides the same functionality.
13276 (Requires_Init_Proc): Return false in case of interface types.
13277 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13279 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13280 is always associated with a predefined primitive because the internal
13281 entities associated with interface types are not predefined primitives.
13282 Therefore, the call to Is_Internal is replaced by a call to the
13283 function Is_Predefined_Dispatching_Operation.
13284 (Make_Eq_If): When generating the list of comparisons for the
13285 components of a given variant, omit the controller component that is
13286 present if the variant has controlled components.
13288 2007-06-06 Javier Miranda <miranda@adacore.com>
13289 Hristian Kirtchev <kirtchev@adacore.com>
13290 Bob Duff <duff@adacore.com>
13292 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13293 handle the creation of finalization lists and calls for nested
13294 coextensions when the root of the chains is part of a return statement.
13295 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13297 (Expand_Record_Equality): Skip components that are interface types.
13298 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13299 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13300 with Rewrite_Coextension. Change the condition for detecting coextension
13302 (Is_Local_Access_Discriminant): Removed.
13303 (Rewrite_Coextension): New routine which rewrites a static coextension
13304 as a temporary and uses its unrestricted access in the construction of
13306 (Complete_Coextension_Finalization): New routine. Generate finalization
13307 attachment calls to all delayed coextensions.
13308 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13309 the allocator is not a coextension itself and has delayed coextensions.
13310 If the current allocator is controlled, but also a coextension, delay
13311 the generation of the finalization attachment call.
13312 Rename local variable "Node" to "Nod" in order to avoid confusion with
13314 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13315 limited types that are not inherently limited. Such an allocator is
13316 illegal, but is generated by the expander for a return statement, to
13317 copy the result onto the secondary stack. This is the only case where a
13318 limited object can be copied. Generate code to displace the pointer
13319 to the object if the qualified expression is a class-wide interface
13320 object. Such displacement was missing and hence the copy of the object
13322 (Apply_Accessibility_Check): Handle allocated objects initialized in
13324 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13325 and Expand_Allocator_Expression. Allocating class-wide interface objects
13326 this routine displaces the pointer to the allocated object to reference
13327 the component referencing the corresponding secondary dispatch table.
13328 Expand_Allocator_Expression): Add missing support to allocate class-wide
13329 interface objects initialized with a qualified expression.
13330 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13331 function result type, and use the finalization list associated with the
13332 function scope in that case (such an anonymous type should not be
13333 treated like an access parameter's type).
13335 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13336 Gary Dismukes <dismukes@adacore.com>
13337 Javier Miranda <miranda@adacore.com>
13339 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13340 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13341 required exception handler.
13342 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13343 properly the case of a function whose return type is a limited
13344 class-wide interface type. Modify the code of the accessibility
13345 check to handle class-wide interface objects. In this case we need to
13346 displace "this" to reference the primary dispatch table to get access
13347 to the TSD of the object (to evaluate its accessibility level).
13348 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13349 rather than a controlling result as one of the conditions for
13350 generating tests of the implicit BIP_Alloc_Form formal. The
13351 initialization assignment is also handled according to whether the
13352 result is tagged instead of controlling.
13353 In the case where the init assignment is inserted in the "then" part of
13354 the allocation conditional, rewrite the target to be a dereference of
13355 the implicit BIP_Object_Access formal.
13356 If the returned value is unconstrained and created on the secondary
13357 stack, mark the enclosing block and function so that the secondary
13358 stack is not reclaimed on return.
13359 Treat returns from functions with controlling results similarly to
13360 returns from functions with unconstrained result subtypes.
13361 If the object returned is unconstrained, and an allocator must be
13362 created for it, analyze the allocator once the block for the extended
13363 return is installed, to ensure that finalizable components
13364 of the expression use the proper finalization list. Guard the call to
13365 Move_Final_List with a check that there is something to finalize.
13366 (Make_Tag_Ctrl_Assignment): Use "old" handling
13367 of controlled type assignment for virtual machines, since new code uses
13368 unsupported features (such as direct access to bytes in memory).
13370 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13371 Ed Schonberg <schonberg@adacore.com>
13373 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13374 accessibility actual, check for the case of an aliased object that has
13375 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13376 we fall into processing for the attribute rather than the name of the
13378 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13379 formal has its address taken in the body, create a temporary to capture
13380 value. If the return type is a limited interface, do not treat the
13381 return value as Controlled.
13382 (Is_In_Place_Function): If the return type is a limited interface,
13383 treat as returning in place. The actual returned object may not always
13384 be limited, but the caller has to assume that it is returned in place.
13385 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13386 context of an allocator, use the correct finalization chain (that is,
13387 the chain belonging to the access type, rather than the chain belonging
13388 to the current scope).
13389 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13390 result type rather than a controlling result as a precondition for
13391 adding an allocation form actual to a build-in-place call.
13392 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13393 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13394 primitive in the dispatch tables. This work is now done by Make_DT when
13395 the type is frozen.
13396 (Register_Predefined_DT_Entry): Removed.
13397 (Add_Return): If end label is not present, use sloc of last statement
13398 for generated return statement in procedure, for better gdb behavior
13400 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13401 object address nodes to ensure proper processing by routines like
13403 (Expand_Call): Fix generation of validity check for parameter
13404 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13405 the allocation form parameter if the result subtype is constrained,
13406 except when the function has a controlling result.
13407 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13408 rather than Is_Controlled and Has_Controlled_Component, since we want to
13409 include class-wide result types in this treatment. Also test for a
13410 controlling result, since that also requires passing a finalization
13412 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13413 even when the result subtype is constrained, to handle calls involving
13414 controlling results.
13415 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13416 is now called even when the result subtype is constrained, to handle
13417 calls involving controlling results.
13418 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13419 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13420 now performs the test).
13421 (Make_Build_In_Place_Call_In_Object_Declaration):
13422 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13423 constrained, to handle calls involving controlling results.
13424 (Add_Return): Accomodate rewritten pattern from local raise to goto

13445 subprogram instead of a plain "raise Program_Error" node to raise
13446 Program_Error if an exception is propagated from an Adjust or Finalize
13448 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13449 appears in the optional statement list of a triggering alternative, the
13450 scope actions can be inserted directly there, and not in the list that
13451 includes the asynchronous select itself.

13481 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13482 functionality when the backend is generating code.
13483 Otherwise any serious error
13484 reported by the backend calling the frontend routine Error_Msg
13485 changes the Compilation_Mode to Check_Semantics, disables the

13526 deallocation of class-wide interface objects.
13527 (Expand_Dispatching_Constructor_Call): Take into account that if the
13528 result of the dispatching constructor is an interface type, the
13529 function returns a class-wide interface type; otherwise the returned
13530 object would be actual. The frontend previously accepted returning
13531 interface types because Expand_Interface_Actuals silently performed
13532 the management of the returned type "as if" it were a class-wide
13534 (Expand_Dispatching_Constructor_Call): Replace call to
13535 Make_DT_Access_Action by direct call to Make_Function_Call.

13597 considererd limited.
13598 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13599 should be declared as limited and that it will be considererd limited.

13627 subtype from the function call, as is done for private types.
13628 (Side_Effect_Free): An expression that is the renaming of an object or
13629 whose prefix is the renaming of a object, is not side-effect free
13630 because it may be assigned through the renaming and its value must be
13631 captured in a temporary.

13711 generated function to the freezing actions of the type.
13712 (Find_Type): A protected type is visible right after the reserved word

13744 defined in GNAT.IO, which might not be stdout
13745 (Is_Valid): Adjust comment to mention that a positive reply means that
13746 Header_Of may be used to retrieve the allocation header associated with

13771 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13774 2007-06-06 Vincent Celier <celier@adacore.com>
13777 Add 3 spaces before the default project directory when displaying
13778 the project search path.

14384 both entities. This is required to statically build the dispatch table.
14385 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14386 of calling Set_All_DT_Position to re-evaluate the position of the
14387 entries in the dispatch table. Such reevaluation is not desired if

15256 (Resolve_Call): If the call returns an array, the context imposes the
15257 component type of the array, and the function has one non-defaulted
15258 parameter, rewrite the call as the indexing of a call with a single
15259 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15261 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15262 the master of the created object is the innermost enclosing statement.
15263 (Remove_Conversions): For a binary operator, check if type of second
15264 formal is numeric, to check if an abstract interpretation is present

15363 overriding" is subtly different from "is abstract" (see AI-228).
15364 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15365 Is_Abstract_Type. Make sure these are called only when appropriate.

15511 that use (a subtype of) the class-wide type of the enclosing type.
15512 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass

15514 Check_Anonymous_Access_Components rather than Empty.
15515 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15516 a record extension in deciding whether to create a class-wide type,

15597 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15598 when -gnatg is not specified.

15650 parameter of the containing subprogram.
15651 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15652 under No_Dispatching_Calls restriction. During the semantic analysis

15705 (Expand_Dispatching_Call): Replace generation of call to the run-time
15706 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15707 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15709 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15710 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15724 check violation of restriction No_Dispatching_Calls.
15725 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15732 specify Any_Limited_Interface, and this functionality is already
15733 provided by the function Has_Abstract_Interfaces.
15734 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15735 support concurrent types implementing interfaces.
15736 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15754 Cyrille Comar <comar@adacore.com>
15756 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15757 anonymous, use finalization list of enclosing dynamic scope.
15758 (Expand_N_Package_Declaration): For a library package declaration
15759 without a corresponding body, generate RACW subprogram bodies in the
15760 spec (just as we do for the task activation call).
15761 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15762 Is_Abstract_Type. Make sure these are called only when appropriate.
15763 Remove all code for DSP option
15764 (CW_Or_Controlled_Type): new subprogram.

15770 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15771 parameter. If it is set to true, return a result capped according to
15772 the global upper bound for the index of an entry family.
15773 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15774 (Build_Find_Body_Index): Adjust for above change.
15775 (Entry_Index_Expression): Likewise.
15776 (Is_Potentially_Large_Family): New function extracted from...

15778 is potentially large.
15779 (Build_Entry_Count_Expression): If the family is potentially large, call
15780 Family_Size with 'Cap' set to true.
15781 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15782 a protected version of an operation declared in the private part of
15783 a protected object, because they may be invoked through a callback.
15784 (Set_Privals): If the type of a private component is an anonymous access
15785 type, do not create a new itype for each protected body.
15786 If the body of a protected operation creates
15787 controlled types (including allocators for class-widetypes), the
15788 body of the corresponding protected subprogram must include a
15790 (Build_Activation_Chain_Entity): Build the chain entity for extended
15792 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15793 to determine whether operation overrides an inherited primitive.

15795 for a possible overriding candidate.
15796 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15797 hold an actual parameter value since its initialization is separated

15801 2007-04-06 Thomas Quinot <quinot@adacore.com>
15802 Pablo Oliveira <oliveira@adacore.com>
15804 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15805 Do an Unchecked_Conversion to handle the passage from the Underlying
15806 Type to the Base Type when calling Build_To_Any_Call and
15807 Build_From_Any_Call.
15808 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15809 E_Constant, depending upon Variable formal.
15810 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15811 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15812 parameter that requires an extra constrained parameter, declare
15813 temporary for actual as a variable, not a constant.
15814 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15815 the unit being compiled is the one that contains the stub type.
15816 Change primitive operation name for the RACW associated with a RAS
15817 from Call to _Call so it cannot clash with any legal identifier.
15818 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15820 (Append_RACW_Bodies): New subprogram.
15821 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15822 Add_Receiving_Stubs_To_Declarations functions.
15823 When expanding a package body, this list correspond to the
15824 statements in the HSS at the end of the pacakge.
15825 When expanding a package spec, this list correspond to the
15827 (Add_Receiving_Stubs_To_Declarations): Append the function
15828 registering the receiving stubs at the end of the 'Stmts' list.
15829 (RCI_Package_Locator): Pass the new Version generic formal when
15830 instantiating a RCI_Locator package.
15831 (Build_From_Any_Function): To compute the High bound for an
15832 unconstrained array actual, we add the Low bound with the length.
15833 Thus we must convert the low bound and the length to an appropriate
15834 type before doing the sum.
15835 (Build_Subprogram_Receiving_Stubs, PolyORB):
15836 * Retrieve the extra formals parameters at the
15837 end of the parameter stream.
15838 * Use Move_Any_Value to write back out parameters
15839 after executing the request as it is more efficient
15840 than Copy_Any_Value.
15841 * Build the any containing Extra Formals with the
15842 appropriate typecode.
15843 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15844 empty Component_List.
15845 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15846 the tree the declaration for an object that serves as actual parameter
15847 in server-side stubs.
15848 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15849 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15850 Use Build_Actual_Object_Declaration to prepare the actuals.

15857 function with the first not implicit parent type.
15858 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15859 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15860 typecode from the Etype. Therefore we retrieve the correct typecode
15861 with a call to Get_Any_Type.
15862 (Copy_Specification): Do controlling formal type substitution based on
15863 Is_Controlling_Formal flag, instead of caller-provided object type.
15864 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15865 a RACW primitive operation, we might get a subprogram declaration for an
15866 ancestor of the RACW designated type (not for the designated type
15867 itself), in the case where this operation is inherited. In this case we
15868 have no easy means of determining the original tagged type for which
15869 the primitive was declared, so instead we now rely on
15870 Copy_Specification to use the Is_Controlling_Formal flag to determine
15871 which formals require type substitution.

15877 GNAT.Current_Exception are not allowed if pragma Restrictions
15878 (No_Exception_Propagation) is set and in any case make the associated
15879 handler unsuitable as a target for a local raise statement.
15880 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15881 run-time subprogram CW_Membership by call to Build_CW_Membership.
15882 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15883 by a function call, a temporary must be created before expanding the
15884 Constructor_Call itself, to prevent out-of-order elaboration in the
15885 back-end when stack checking is enabled..
15887 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15889 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15890 result are the bounds of the left operand, not the right.
15892 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15895 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15907 box corresponds to a component of the type.
15908 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15909 Is_Abstract_Subprogram and Is_Abstract_Type.

16014 standard 8bits encoding.
16015 (WS2SU): As above but converting from wide-sring to string.
16016 This is needed as it is necessary to have access to both versions in the
16017 runtime for the form parameter encoding support.
16018 This set of patch add support for the encoding form parameter.
16019 (S2WS): Improve implementation to handle cases where the filename is not
16020 UTF-8 encoded. In this case we default to using the current code page
16021 for the conversion.

16068 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16069 __gnat_adjust_context_for_raise.
16070 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16071 implementation of floating point operations as native x86 targets.
16072 So the FPU should be initialized in the same way using finit. Fix
16073 floating point operations accuracy issues.

16091 Javier Miranda <miranda@adacore.com>
16093 * lib-xref.ads, lib-xref.adb:
16094 Modify the loop that collects type references, to include interface
16095 types that the type implements. List each of these interfaces when
16096 building the entry for the type.
16097 (Generate_Definition): Initialize component Def and Typ of new entry
16098 in table Xrefs, to avoid to have these components unitialized.

16144 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16145 it no longer destroys the contents of Name_Buffer or Name_Len and
16146 non-standard and invalid names are handled better.
16147 (Get_Decoded_Name_String): Improve performance by using
16148 Name_Has_No_Encodings flag in the name table.
16149 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16150 Used for debugging printouts.

16156 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16157 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16158 there is no need to generate always a record_definition_node in case
16159 of synchronized interface types.
16160 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16161 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16162 illegal in Ada 95, in cases where it is legal. Change the warnings to
16163 errors in other cases. Don't give the error unless the "not null"
16164 parses properly. Correct the source position at which the error occurs.
16165 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16166 P_Null_Exclusion, to suppress "not null" warnings.

16218 Entry for pragma Unreferenced_Objects
16220 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD

16242 the default project path, initially done during elaboration of the
16244 If the prefix returned by Sdefault is null, get the prefix from a call
16245 to Executable_Prefix_Path.
16246 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16249 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16250 canonical directory name to open the directory from which files are
16252 (Record_Other_Sources): Idem.
16253 (Locate_Directory): Add the possibility to create automatically missing
16254 directories when Setup_Projects is True.
16255 Call Locate_Directory so that the directory will be created when
16256 Setup_Projects is True, for object dir, library dir, library ALI dir,
16257 library source copy dir and exec dir.
16259 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16262 2007-04-06 Robert Dewar <dewar@adacore.com>

16297 full word is no longer compared twice.
16299 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16301 * sem_ch10.adb (Install_Limited_Context_Clauses.
16302 Expand_Limited_With_Clause): Use a new copy of selector name in the
16303 call to Make_With_Clause. This fixes the tree structure for ASIS
16304 purposes. Nothing is changed in the compiler behaviour.
16305 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16306 a package renaming.
16307 (Install_Limited_With_Clauses): Do not install non-limited view when it
16308 is still incomplete.
16310 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16311 Gary Dismukes <dismukes@adacore.com>
16313 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16314 when capturing size information, instead of base type, which for a
16315 formal array type will be the unconstrained type.
16316 (Analyze_Formal_Object_Declaration): Add check for illegal default
16317 expressions for a formal in object of a limited type.
16318 (Instantiate_Object): Ditto.
16319 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16320 because they were defaulted in the formal package and no check applies
16322 (Check_Formal_Package_Instance): Extend conformance check to other
16323 discrete types beyond Integer.
16324 (Process_Default): Copy directly the unmatched formal. A generic copy
16325 has already been performed in Analyze_Formal_Package.
16326 (Analyze_Associations): If a formal subprogram has no match, check for
16327 partial parametrization before looking for a default, to prevent
16329 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16330 not set the instantiation environment before analyzing the actuals.
16331 Fixes regression on 8515-003 with implementation of AI-133.
16332 Set_Instance_Env checks whether the generic unit is a predefined
16333 unit, in which case the instance must be analyzed with the latest Ada
16334 mode. This setting must take place after analysis of the actuals,
16335 because the actuals must be analyzed and frozen in the Ada mode extant
16336 outside of the current instantiation.
16337 (Save_Env, Restore_Env): Preserve and restore the configuration
16338 parameters so that predefined units can be compiled in the proper Ada
16340 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16341 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16342 and Is_Abstract_Type.
16343 (Analyze_Formal_Package): For better error recovery, Add exception
16344 handler to catch Instantion_Error, which can be raised in
16345 Analyze_Associations
16347 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16348 Bob Duff <duff@adacore.com>
16349 Gary Dismukes <dismukes@adacore.com>
16351 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16352 prefix type is a discriminated subtype of the type of the formal.
16353 (Analyze_Allocator): Collect all coextensions regardless of the context.
16354 Whether they can be allocated statically is determined in exp_ch4.
16355 (Analyze_Selected_Component): If the prefix is a limited view and the
16356 non-limited view is available, use the non-limited one.
16357 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16358 therefore illegal), suggest a qualified expression rather than a type
16359 conversion, because a type conversion would be illegal in this context.
16360 (Anayze_Allocator): Trace recursively all nested allocators so that all
16361 coextensions are on the corresponding list for the root. Do no mark
16362 coextensions if the root allocator is within a declaration for a stack-
16363 allocated object, because the access discriminants will be allocated on
16365 (Analyze_Call): Remove restriction on calls to limited functions for the
16366 cases of generic actuals for formal objects, defaults for formal objects
16367 and defaults for record components.
16368 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16369 element list. Their expansion is delayed until the enclosing allocator
16370 is processed and its finalization list constructed.
16371 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16372 for an operation with the given name among the primitive operations of
16373 the corresponding record type.
16374 (Analyze_Selected_Component): If the prefix is a task type that
16375 implements an interface, and there is no entry with the given name,
16376 check whether there is another primitive operation (e.g. a function)
16378 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16379 properly the indexing of a function call written in prefix form, where
16380 the function returns an array type, and all parameters of the function
16381 except the first have defaults.
16382 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16383 the original operands, rather than relocating them, for efficiency and
16384 to work properly when an operand is overloaded.
16385 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16386 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16387 (Analyze_Selected_Component): If the prefix is a private extension, only
16388 scan the visible components, not those of the full view.
16389 (Try_Primitive_Operation): If the operation is a procedure, collect all
16390 possible interpretations, as for a function, because in the presence of
16391 classwide parameters several primitive operations of the type can match
16392 the given arguments.
16394 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16395 Robert Dewar <dewar@adacore.com>
16397 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16398 tag-indeterminate call to an abstract function, when the left-hand side
16400 (Analyze_Loop_Statement): Improve detection of infinite loops
16402 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16403 Thomas Quinot <quinot@adacore.com>
16405 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16406 out of Analyze_Package_Declaration, because processing must be applied
16407 to package bodies as well, for deferred constants completed by pragmas.
16408 (Analyze_Package_Declaration): When the package declaration being
16409 analyzed does not require an explicit body, call Check_Completion.
16410 (May_Need_Implicit_Body): An implicit body is required when a package
16411 spec contains the declaration of a remote access-to-classwide type.
16412 (Analyze_Package_Body): If the package contains RACWs, append the
16413 pending subprogram bodies generated by exp_dist at the end of the body.
16414 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16415 Is_Abstract_Subprogram and Is_Abstract_Type.
16416 (Preserve_Full_Attributes): The full entity list is not an attribute
16417 that must be preserved from full to partial view.
16419 * sem_dist.adb (Add_RAS_Dereference_TSS):
16420 Change primitive name to _Call so it cannot clash with any legal
16421 identifier, and be special-cased in Check_Completion.
16422 Mark the full view of the designated type for the RACW associated with
16423 a RAS as Comes_From_Source to get proper view switching when installing
16424 private declarations.
16425 Provite a placeholder nested package body along with the nested spec
16426 to have a place for Append_RACW_Bodies to generate the calling stubs
16427 and stream attributes.
16429 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16430 Robert Dewar <dewar@adacore.com>
16432 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16433 that is a limited view, check the non-limited view if available.
16434 (Undefined): Refine error message for missing with of Text_IO
16435 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16436 to distinguish real missing with cases.
16437 Fix format of all missing with messages
16438 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16439 renaming as body when renamed entity is abstract.
16441 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16442 Javier Miranda <miranda@adacore.com>
16444 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16445 predicate recursive, to handle complex expressions on literals whose
16446 spurious ambiguity comes from the abstract interpretation of some
16448 (Interface_Present_In_Ancestor): Add support to concurrent record
16450 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16451 Is_Abstract_Subprogram and Is_Abstract_Type.
16453 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16454 Javier Miranda <miranda@adacore.com>
16456 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16457 dereference of a local object R created as a reference to another
16458 object O, use the access level of O.
16459 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16460 rather than local Same_Formal_Type, to check whether protected operation
16461 overrides an inherited one.
16462 (Same_Formal_Type): New predicate, used when matching signatures of
16463 overriding synchronized operations, to handle the case when a formal
16464 has a type that is a generic actual.
16465 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16466 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16467 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16468 syntactic ambiguities involving indexing of function calls that return
16470 (Abstract_Interface_List): New subprogram that returns the list of
16471 abstract interfaces associated with a concurrent type or a
16472 concurrent record type.
16473 (Interface_Present_In_Parent): New subprogram used to check if a
16474 given type or some of its parents implement a given interface.
16475 (Collect_Abstract_Interfaces): Add support for concurrent types
16476 with interface types.
16477 (Has_Abstract_Interfaces): Add support for concurrent types with
16479 (Is_Parent): New subprogram that determines whether E1 is a parent
16480 of E2. For a concurrent type its parent is the first element of its
16481 list of interface types; for other types this function provides the
16482 same result than Is_Ancestor.
16483 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16484 (Collect_Synchronized_Interfaces): Removed because the subprogram
16485 Collect_Abstract_Interfaces provides this functionality.
16486 (Collect_Abstract_Interfaces): Minor update to give support to
16487 concurrent types and thus avoid undesired code duplication.
16488 (Get_Subprogram_Entity): Handle entry calls.
16489 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16491 (Enter_Name): Do not give -gnatwh hiding warning for record component
16492 entities, they never result in hiding.

16497 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
16498 to chain nested components that are allocators for access discriminants
16499 of the enclosing object.

16501 New field Exception_Label added
16502 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16503 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

16505 correspond to access discriminants of dynamically allocated objects.
16506 (N_Block_Statement): Document the fact that the corresponding entity
16507 can be an E_Return_Statement.
16508 (Is_Coextension): New flag for allocators.

16516 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16517 before propagating exception.
16519 2007-04-06 Olivier Hainque <hainque@adacore.com>
16521 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16522 an address always within the call instruction from a return address.
16524 2007-04-06 Olivier Hainque <hainque@adacore.com>
16525 Eric Botcazou <botcazou@adacore.com>
16527 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16528 expression with a COMPOUND_EXPR including the call instead of emitting
16529 the call directly here.
16530 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16531 high bound is constant and the slice is empty. Tidy.
16532 (tree_transform, case N_Op_Not): Handle properly the case where the
16533 operation applies to a private type whose full view is a modular type.
16534 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16535 Address_Clause, use the associated Expression as the GNAT tree
16536 representing the choice value to ensure the corresponding GCC tree is
16537 of the proper kind.
16538 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16539 instead of just the operands, as the base GCC stabilize_reference does.
16540 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16541 requested; otherwise fail.
16542 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16544 2007-04-06 Thomas Quinot <quinot@adacore.com>

16547 implementation of UI_Div.
16548 (UI_Div): Reimplement as a call to UI_Div_Rem.
16549 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16550 remainder, avoiding the cost of a multiplication and a subtraction.
16551 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16552 provides both quotient and remainder in a single computation.
16553 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16554 functions for uint.
16555 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16556 is undefined if the given n is not inversible.
16558 2007-04-06 Olivier Hainque <hainque@adacore.com>
16560 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
16561 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion
16564 2007-04-06 Eric Botcazou <botcazou@adacore.com>
16565 Olivier Hainque <hainque@adacore.com>
16567 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16568 when updating the contents of the old pointer to an unconstrained array.
16569 (end_subprog_body): Set error_gnat_node to Empty.
16570 (write_record_type_debug_info): Do not be unduly sparing with our bytes.
16571 (unchecked_convert): For subtype to base type conversions, require that
16572 the source be a subtype if it is an integer type.

16822 anonymous access types.
16823 (Valid_Conversion): For a conversion to a numeric type occurring in an
16824 instance or inlined body, no need to check that the operand type is
16825 numeric, since this has been checked during analysis of the template.

17530 the parent part is a build-in-place function call, generate assignments.
17531 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17532 are build-in-place function calls.
17533 (Replace_Self_Reference): New subsidiary of
17534 Make_OK_Assignment_Statement, to replace an access attribute that is a
17535 self-reference into an access to the appropriate component of the
17536 target object. Generalizes previous mechanism to handle self-references
17537 nested at any level.
17538 (Is_Self_Referential_Init): Remove, not needed.
17539 (Is_Self_Referential_Init): New predicate to simplify handling of self
17540 referential components in record aggregates.
17541 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17542 check for presence of entity before checking for self-reference.
17543 (Has_Default_Init_Comps): Return True if a component association is a
17544 self-reference to the enclosing type, which can only come from a
17545 default initialization.
17546 (Make_OK_Assignment_Statement): If the expression is of the form
17547 Typ'Acc, where Acc is an access attribute, the expression comes from a
17548 default initialized self-referential component.
17549 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17550 that has been derived from several abstract interfaces we must also
17551 initialize the tags of the secondary dispatch tables.

17556 Robert Dewar <dewar@adacore.com>
17559 (Expand_Access_To_Protected_Op): If the context indicates that an access
17560 to a local operation may be transfered outside of the object, create an
17561 access to the wrapper operation that must be used in an external call.
17562 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17563 target, pass the Valid attribute applied to a floating-point prefix on
17564 to the back end without expansion.
17565 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17566 the allocated storage when it is specified by a per-object expression.
17567 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17568 Nothing to do here, the attribute has been rewritten during semantic

17572 (Find_Fat_Info): Handle case of universal real
17573 (Expand_Access_To_Protected_Op): Fix use of access to protected
17574 subprogram from inside the body of a protected entry.
17575 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17576 'Access and 'Unrestricted_Access, to transform the attribute reference
17577 into a fat pointer.
17578 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17579 subcomponent's enclosing variable is aliased with a constrained subtype.
17580 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17581 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17582 an aliased prefix must be known to be constrained in order to use True
17583 for the attribute value, and now it's possible for some aliased views
17584 to be unconstrained.
17586 2006-10-31 Robert Dewar <dewar@adacore.com>
17588 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17589 (Expand_Entity_Reference): Correct error of not handling subprogram
17590 formals in current_value processing.
17592 2006-10-31 Javier Miranda <miranda@adacore.com>

17594 Ed Schonberg <schonberg@adacore.com>
17595 Gary Dismukes <dismukes@adacore.com>
17597 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17598 register in the final list objects containing class-wide interfaces;
17599 otherwise we incorrectly register the tag of the interface in the final
17601 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17602 generate the wrapper if the parent primitive is abstract. This is
17603 required to report the correct error message.
17604 (Expand_N_Subtype_Indication): Do validity checks on range
17605 (Clean_Task_Names): If an initialization procedure includes a call to
17606 initialize a task (sub)component, indicate that the procedure will use
17607 the secondary stack.
17608 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17609 compatibility for interfacing with CPP by default.
17610 (Expand_N_Object_Declaration): Only build an Adjust call when the
17611 object's type is a nonlimited controlled type.
17612 * exp_ch3.adb: Add with and use of Exp_Ch6.
17613 (Expand_N_Object_Declaration): Check for object initialization that is a
17614 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17615 Object_Declaration to the call.
17616 (Freeze_Type): When the designated type of an RACW was not frozen at the
17617 point where the RACW was declared, validate the primitive operations
17618 with respect to E.2.2(14) when it finally is frozen.
17619 (Build_Initialization_Call,Expand_Record_Controller): Rename
17620 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17621 return-by-reference has no meaning in Ada 2005.
17622 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17623 to register tag of the immediate ancestor interfaces in the
17624 run-time structure.
17625 (Init_Secondary_Tags): Moved to the specification to allow the
17626 initialization of extension aggregates with abstract interfaces.
17627 (Build_Master_Renaming): Make public, for use by function declarations
17628 whose return type is an anonymous access type.
17629 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17630 Insert_List_Before_And_Analyze after the generation of the specs
17631 associated with null procedures.
17632 (Expand_Tagged_Root): Update documentation in its specification.
17633 (Init_Secondary_Tags): Update documentation.
17634 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17635 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17636 then generate code to inherit the contents of the dispatch table
17637 directly from the ancestor.
17638 (Expand_Record_Controller): Insert controller component after tags of
17639 implemented interfaces.
17640 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17641 create null procedure overridings when null procedures are inherited
17643 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17644 declarations for overriding null primitives inherited from interfaces.
17645 (Is_Null_Interface_Procedure): New function in
17646 Make_Null_Procedure_Specs.
17647 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17648 immediate ancestor of a tagged type is an abstract interface type we
17649 must generate the specification of the predefined primitives associated
17650 with controlled types (because the dispatch table of the ancestor is
17651 null and hence these entries cannot be inherited). This is required to
17652 elaborate well the dispatch table.

17660 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17662 (Expand_N_In): Do validity checks on range
17663 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17664 (Expand_N_Allocator): For "new T", if the object is constrained by
17665 discriminant defaults, allocate the right amount of memory, rather than
17666 the maximum for type T.
17667 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17668 when the allocator is initialized by a build-in-place call, since the
17669 allocator is already rewritten as a reference to the function result,
17670 and this prevents an unwanted duplication of the function call.
17671 Add with and use of Exp_Ch6.
17672 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17673 is a call to build-in-place function and apply
17674 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17675 untagged designated types).
17676 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17677 optimization if source or target is biased.
17678 (Expand_N_Allocator): Add comments for case of an allocator within a
17679 function that returns an anonymous access type designating tasks.
17680 (Expand_N_Allocator): apply discriminant checks for access
17681 discriminants of anonymous access types (AI-402, AI-416)

17688 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17690 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17691 (Expand_N_Assignment_Statement): Call
17692 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17693 build-in-place function call. Currently, this can happen only for
17694 assignments that come from aggregates.
17695 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17696 in order to alleviate the upward compatibility introduced by AI-318.
17697 (Expand_N_Extended_Return_Statement): Add support for handling the
17698 return object as a build-in-place result.
17699 (Expand_Non_Function_Return): Implement simple return statements nested
17700 within an extended return.
17701 (Enable_New_Return_Processing): Turn on the new processing of return
17703 (Expand_Non_Function_Return): For a return within an extended return,
17704 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17705 (Expand_N_Extended_Return_Statement): Implement AI-318
17706 (Expand_Simple_Function_Return): Ditto.
17707 (Expand_N_If_Statement): Handle new -gnatwt warning
17708 (Expand_N_Case_Statement): Handle new -gnatwt warning
17709 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17710 a protected object.
17711 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17712 validity checking of assignments to elementary record components.
17713 (Expand_N_Return_Statement): return Class Wide types on the secondary
17714 stack independantly of their controlled status since with HIE runtimes,
17715 class wide types are not potentially controlled anymore.
17717 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17720 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17721 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17722 it expects a block, procedure, or task. The return statement will get
17723 turned into a block, and Expand_Cleanup_Actions will happen then.

17727 Bob Duff <duff@adacore.com>
17728 Gary Dismukes <dismukes@adacore.com>
17730 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17732 (Expand_Inlined_Call): Tagged types are by-reference types, and
17733 therefore should be replaced by a renaming declaration in the expanded
17734 body, as is done for limited types.
17735 (Expand_Call): If this is a call to a function with dispatching access
17736 result, propagate tag from context.
17737 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17739 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17740 build-in-place when the right-hand side of an assignment is a
17741 build-in-place function call.
17742 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17743 of the explicit dereference of the allocator to the result subtype of
17744 the build-in-place function. This is needed to satisfy type checking
17745 in cases where the caller's return object is created by an allocator for
17746 a class-wide access type and the type named in the allocator is a
17748 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17749 conversion of the reference to the declared object to the result subtype
17750 of the build-in-place function. This is needed to satisfy type checking
17751 in cases where the declared object has a class-wide type. Also, in the
17752 class-wide case, change the type of the object entity to the specific
17753 result subtype of the function, to avoid passing a class-wide object
17754 without explicit initialization to the back end.
17755 (Register_Interface_DT_Entry): Moved outside the body of
17756 Freeze_Subprogram because this routine is now public; it is called from
17757 Check_Dispatching_Overriding to handle late overriding of abstract
17758 interface primitives.
17759 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17760 adding an implicit access actual on a call to a build-in-place function.
17761 (Expand_Actuals): Test for an actual parameter that is a call to a
17762 build-in-place function and apply
17763 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17764 (Is_Build_In_Place_Function): New function to determine whether an
17765 entity is a function whose calls should be handled as build-in-place.
17766 (Is_Build_In_Place_Function_Call): New function to determine whether an
17767 expression is a function call that should handled as build-in-place.
17768 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17769 calls to build-in-place functions as the initialization of an allocator.
17770 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17771 handling calls to build-in-place functions in contexts that do not
17772 involve init of a separate object (for example, actuals of subprogram
17774 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17775 handling calls to build-in-place functions as the initialization of an
17776 object declaration.
17777 (Detect_Infinite_Recursion): Add explicit parameter Process to
17778 instantiation of Traverse_Body to avoid unreferenced warning.
17779 (Check_Overriding_Inherited_Interfaces): Removed.
17780 (Register_Interface_DT_Entry): Code cleanup.
17781 (Register_Predefined_DT_Entry): Code cleanup.
17782 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17783 inlined statements if within a transient scope.
17784 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17785 formal parameters with occurrences of actuals in inlined body, establish
17786 visibility on the proper view of the actual's subtype for the body's
17788 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17789 compatibility mode and we have an imported CPP subprogram because
17790 for now we assume that imported CPP primitives correspond with
17791 objects whose constructor is in the CPP side (and therefore we
17792 don't need to generate code to register them in the dispatch table).
17793 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17794 aligned selected component.
17795 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17796 the actual of an in-mode parameter is a type conversion.
17797 (Expand_Actuals): If the call does not come from source and the actual
17798 is potentially misaligned, let gigi handle it rather than rejecting the
17799 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17800 Class Wide types as returning by reference independantly of their
17801 controlled status since with HIE runtimes class wide types are not
17802 potentially controlled anymore.
17804 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17806 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17807 references that are private components of the protected object.

17809 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17810 instantiation to deal with warnings.

17812 System_Priority as its expected type, in case the expression has not
17815 2006-10-31 Robert Dewar <dewar@adacore.com>
17817 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17818 initialization of Homonym_Len.
17819 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17820 names from fully qualified name. Fixes problem of duplicate
17821 external names differing only in the presence of such a block name.
17823 2006-10-31 Thomas Quinot <quinot@adacore.com>
17824 Pablo Oliveira <oliveira@adacore.com>
17826 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17827 subprogram Ids, even if they are not yet assigned.
17828 (Build_Subprogram_Id): It is now this function that will take care of
17829 calling Assign_Subprogram_Ids if necessary.
17830 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17831 should be done only once they are assigned.
17832 (Build_From_Any_Function, case of tagged types): Add missing call to
17834 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17835 type for an RACW type.
17836 (Add_RACW_Features): When processing an RACW declaration for which the
17837 designated type is already frozen, enforce E.2.2(14) rules immediately.
17838 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17839 special reordering of controlling formals.
17841 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17842 associated stub type for an RACW type.
17844 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17846 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17847 fixed-point operations in an integer context, i.e. as operands of a
17848 conversion to an integer type, indicate that result must be rounded.
17850 2006-10-31 Robert Dewar <dewar@adacore.com>
17852 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17853 cases, pass the encoding method, since it is now required by the run
17856 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17857 assumption that Str'First = 1.
17858 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17859 it on to the Value_Wide_Wide_Character call.
17860 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17861 properly handles a string of the form quote-encoded_wide_char-quote.
17863 * s-wchcnv.adb: Minor reformatting
17865 2006-10-31 Javier Miranda <miranda@adacore.com>
17867 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17868 run-time membership test to ensure that the constructed object
17869 implements the target abstract interface.
17871 2006-10-31 Robert Dewar <dewar@adacore.com>
17873 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17874 Machine_Attribute pragma internally to implement the user pragma.
17875 Add processing for pragma Interface so that it is now completely
17876 equivalent to pragma Import.
17878 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17879 so that it can be applied to all entities, including record components
17880 and enumeration literals.
17881 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17882 priority ranges are correct, verify compatibility against task
17883 dispatching and locking policies, and if everything is correct an entry
17884 is added to the table containing priority specific dispatching entries
17885 for this compilation unit.
17886 (Delay_Config_Pragma_Analyze): Delay processing
17887 Priority_Specific_Dispatching pragmas because when processing the
17888 pragma we need to access run-time data, such as the range of
17889 System.Any_Priority.
17890 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17891 Allow pragma Unreferenced as a context item
17892 Add pragma Preelaborable_Initialization

17894 now syntactically and semantically equivalent to Import.
17895 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17896 insertion characters.
17897 Add handling for Pragma_Wide_Character_Encoding
17898 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17899 never supercedes a real restriction, and that a real restriction
17900 always supercedes a warning.
17901 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17905 Ed Schonberg <schonberg@adacore.com>
17906 Robert Dewar <dewar@adacore.com>
17908 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17909 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17910 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17912 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17913 type of the function containing a return statement, because the
17914 Return_Type field was removed. We now use the Return_Applies_To field.
17916 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17917 (Build_Task_Image_Decl): If procedure is not called from an
17918 initialization procedure, indicate that function that builds task name
17919 uses the sec. stack. Otherwise the enclosing initialization procedure
17920 will carry the indication.
17921 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17922 N_Object_Declaration instead.
17923 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17924 conditional dead code killed, and change implementation accordingly.
17925 (Insert_Actions): Add N_Return_Object_Declaration case.
17926 Correct comment to mention N_Extension_Aggregate node.
17927 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17928 attempts to save information for global variables which cannot be
17930 (Get_Current_Value_Condition): Handle conditions the other way round
17931 (constant on left). Also handle right operand of AND and AND THEN
17932 (Set_Current_Value_Condition): Corresponding changes
17933 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17934 (Get_Current_Value_Condition): Handle simple boolean operands
17935 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17936 (Get_Current_Value_Condition): If the variable reference is within an
17937 if-statement, does not appear in the list of then_statments, and does
17938 not come from source, treat it as being at unknown location.
17939 (Get_Current_Value_Condition): Enhance to allow while statements to be
17940 processed as well as if statements.
17941 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17943 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17944 of loop. This is safe now that we fixed Kill_Current_Values.
17945 (OK_To_Do_Constant_Replacement): Check whether current scope is
17946 Standard, before examining outer scopes.
17948 2006-10-31 Vincent Celier <celier@adacore.com>

17951 When True, apply VMS treatment to children of packages A, G, I and S.
17954 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17956 2006-10-31 Robert Dewar <dewar@adacore.com>
17957 Ed Schonberg <schonberg@adacore.com>

17960 (Warn_Overlay): Supply missing continuation marks in error msgs
17961 (Freeze_Entity): Add check for Preelaborable_Initialization
17963 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17965 * g-expect.adb: Add Warnings (Off) to prevent new warning
17967 * lib-xref.adb: Add handling of Last_Assignment field
17968 (Generate_Reference): Centralize handling of pragma Obsolescent here
17969 (Generate_Reference): Accept an implicit reference generated for a
17970 default in an instance.
17971 (Generate_Reference): Accept a reference for a node that is not in the
17972 main unit, if it is the generic body corresponding to an subprogram
17975 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17977 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17979 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17981 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17982 use clauses, to avoid messages on packages used to qualify, and also
17983 to avoid messages from obsolescent units.
17984 (Warn_On_Useless_Assignments): Don't generate messages for imported
17985 and exported variables.
17986 (Warn_On_Useless_Assignments): New procedure
17987 (Output_Obsolescent_Entity_Warnings): New procedure
17988 (Check_Code_Statement): New procedure
17990 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

17992 (Last_Assignment): New field for useless assignment warning
17994 2006-10-31 Olivier Hainque <hainque@adacore.com>
17996 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17997 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17999 2006-10-31 Bob Duff <duff@adacore.com>
18000 Robert Dewar <dewar@adacore.com>
18001 Ed Schonberg <schonberg@adacore.com>
18003 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18004 Ada 95 mode, because it violates the new rules for AI-318.
18006 * g-awk.ads: Use overloaded subprograms in every case where we used to
18007 have a default of Current_Session. This makes the code closer to be
18008 correct for both Ada 95 and 2005.
18010 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18011 code, relying on the fact that the compiler generates a warning
18012 instead of an error in -gnatg mode.
18014 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18015 E_Return_Statement entity kind.
18016 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18018 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18019 report an error if the reserved word abstract has been previously found.
18020 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18022 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18023 parenthesized range attribute usage
18024 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18026 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18027 in the syntax for extended_return_statement. This is not in the latest
18028 RM, but the ARG is expected to issue an AI allowing this.
18029 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18030 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18031 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18032 P_Return_Statement): Parse the new syntax for extended_return_statement.
18034 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18035 Output_End_Missing): Add error-recovery code for the new
18036 extended_return_statement syntax; that is, the new E_Return entry on
18039 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18040 limited to nonlimited, because otherwise we violate the new Ada 2005
18041 rules about returning limited types in function Create_AST_Handler in
18044 * sem.adb (Analyze): Add cases for new node kinds
18045 N_Extended_Return_Statement and N_Return_Object_Declaration.
18047 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18048 type is in the same category as type of context before applying check,
18049 to prevent anomalies in instantiations.
18050 (Resolve_Aggregate): Remove test for limited components in aggregates.
18051 It's unnecessary in Ada 95, because if it has limited components, then
18052 it must be limited. It's wrong in Ada 2005, because limited aggregates
18054 (Resolve_Record_Aggregate): Move check for limited types later, because
18055 OK_For_Limited_Init requires its argument to have been resolved.
18056 (Get_Value): When copying the component default expression for a
18057 defaulted association in an aggregate, use the sloc of the aggregate
18058 and not that of the original expression, to prevent spurious
18059 elaboration errors, when the expression includes function calls.
18060 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18061 were missing. We also didn't handle qualified expressions. Now also
18062 allow function calls. Use new common routine OK_For_Limited_Init.
18063 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18064 with space can upper case letter).
18066 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18067 Has_Static_Discriminants flag
18068 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18069 type with discriminants.
18070 (Process_Range_Expr_In_Decl): Do validity checks on range
18071 (Build_Discriminant_Constraints): Use updated form of
18072 Denotes_Discriminant.
18073 (Process_Subtype): If the subtype is a private subtype whose full view
18074 is a concurrent subtype, introduce an itype reference to prevent scope
18076 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18077 Record_Type_Declaration): The functionality of the subprograms
18078 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18079 is now performed by a single routine.
18080 (Build_Derived_Record_Type): If the type definition includes an explicit
18081 indication of limitedness, then the type must be marked as limited here
18082 to ensure that any access discriminants will not be treated as having
18083 a local anonymous access type.
18084 (Check_Abstract_Overriding): Issue a detailed error message when an
18085 abstract subprogram was not overridden due to incorrect mode of its
18087 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18088 synchronized private extension declarations. Verify that the ancestor is
18089 a limited or synchronized interface or in the generic case, the ancestor
18090 is a tagged limited type or synchronized interface and all progenitors
18091 are either limited or synchronized interfaces.
18092 Derived_Type_Declaration): Check for presence of private extension when
18093 dealing with synchronized formal derived types.
18094 Process_Full_View): Enchance the check done on the usage of "limited" by
18095 testing whether the private view is synchronized.
18096 Verify that a synchronized private view is completed by a protected or
18098 (OK_For_Limited_Init_In_05): New function.
18099 (Analyze_Object_Declaration): Move check for limited types later,
18100 because OK_For_Limited_Init requires its argument to have been resolved.
18101 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18102 in order to alleviate the upward compatibility introduced by AI-318.
18103 (Constrain_Corresponding_Record): If the constraint is for a component
18104 subtype, mark the itype as frozen, to avoid out-of-scope references to
18105 discriminants in the back-end.
18106 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18107 this subprogram against wrong sources.
18108 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18109 discriminant of limited type completed with a protected type, when the
18110 discriminant is used to constrain a private component of the type, and
18111 expansion is disabled.
18112 (Find_Type_Of_Object): Do not treat a return subtype that is an
18113 anonymous subtype as a local_anonymous_type, because its accessibility
18114 level is the return type of the enclosing function.
18115 (Check_Initialization): In -gnatg mode, turn the error "cannot
18116 initialize entities of limited type" into a warning.
18117 (OK_For_Limited_Init): Return true for generated nodes, since it
18118 sometimes violates the legality rules.
18119 (Make_Incomplete_Declaration): If the type for which an incomplete
18120 declaration is created happens to be the currently visible entity,
18121 preserve the homonym chain when removing it from visibility.
18122 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18123 inherited subprograms.
18124 (Access_Definition): If this is an access to function that is the return
18125 type of an access_to_function definition, context is a type declaration
18126 and the scope of the anonymous type is the current one.
18127 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18128 incomplete subtype to the set of private dependents of the original
18130 (Constrain_Discriminated_Type): Emit an error message whenever an
18131 incomplete subtype is being constrained.
18132 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18133 corresponding subtype of the full view of the original incomplete type.
18134 (Check_Incomplete): Properly detect invalid usage of incomplete types
18137 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18139 * g-catiio.ads, g-catiio.adb (Value): New function.

18148 Robert Dewar <dewar@adacore.com>
18150 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18151 handling executable extension manually and duplicating code.
18153 * make.adb: Implement new -S switch
18154 (Gnatmake): Use new function Osint.Executable_Name instead
18155 of handling executable extension manually.
18157 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18158 is specified, the executable name ends with this suffix.
18159 Take advantage of Osint.Executable_Name instead of duplicating code.
18161 * switch-m.adb: Recognize new gnatmake -S switch
18163 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18165 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18168 * makeusg.adb: Add line for gnatmake -S switch
18170 2006-10-31 Vincent Celier <celier@adacore.com>
18172 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18173 call it with -static-libgcc, as there are some platforms, such as
18174 Darwin, where one of these two switches is compulsory to link.
18176 2006-10-31 Vincent Celier <celier@adacore.com>
18178 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18179 instead of ADA_PROJECT_PATH, for the project path.
18180 (Gnatls): When displaying the project path directories, use host dir
18183 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18184 names in the project path, as absolute paths may correspond to
18185 multi-valued VMS logical names.
18187 2006-10-31 Vincent Celier <celier@adacore.com>
18189 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18190 absolute path name.
18191 (Locate_Regular_File): Ditto
18192 (Change_Dir): Remove, no longer used
18193 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18194 on Windows. Get it calling Get_Current_Dir.
18195 (OpenVMS): Remove imported boolean, no longer needed.
18196 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18197 (Pid_To_Integer): New function to convert a Process_Id to Integer
18199 2006-10-31 Thomas Quinot <quinot@adacore.com>
18201 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18202 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18204 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18207 2006-10-31 Robert Dewar <dewar@adacore.com>
18209 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18210 initial letter o as a zero.

18214 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18216 2006-10-31 Robert Dewar <dewar@adacore.com>
18218 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18220 (Layout_Variant_Record): Retrieve the discriminants from the entity
18221 rather than from the type definition, because in the case of a full
18222 type for a private type we need to take the discriminants from the
18224 (Layout_Component_List): When applying the Max operator to variants with
18225 a nonstatic size, check whether either operand is static and scale that
18226 operand from bits to storage units before applying Max.
18227 (Layout_Type): In VMS, if a C-convention access type has no explicit
18228 size clause (and does not inherit one in the case of a derived type),
18229 then the size is reset to 32 from 64.
18231 2006-10-31 Vincent Celier <celier@adacore.com>
18233 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18234 its file has already been loaded, according to the unit being loaded,
18235 not to the current value of Multiple_Unit_Index.
18237 2006-10-31 Thomas Quinot <quinot@adacore.com>
18238 Eric Botcazou <ebotcazou@adacore.com>

18270 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18273 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18275 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18276 Process_Body_Clauses): If the context of a body includes a use clause
18277 for P.Q then a with_clause for P in the same body is not redundant,
18278 even if the spec also has a with_clause on P.
18279 Add missing continuation mark to error msg
18280 (Build_Limited_Views): A limited view of a type is tagged if its
18281 declaration includes a record extension.
18282 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18283 node, even if the subunit has errors. This avoids malfunction by
18284 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18285 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18286 generation of obsolescent messages for with statements (cannot do
18287 this too early, or we cannot implement avoiding the messages in the
18288 case of obsolescent units withing obsolescent units).
18289 (Install_Siblings): If the with_clause is on a remote descendant of
18290 an ancestor of the current compilation unit, find whether there is
18291 a sibling child unit that is immediately visible.
18292 (Remove_Private_With_Clauses): New procedure, invoked after completing
18293 the analysis of the private part of a nested package, to remove from
18294 visibility the private with_clauses of the enclosing package
18296 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18297 now centralized in Generate_Reference.
18298 (Install_Limited_Context_Clauses): Remove superfluous error
18299 message associated with unlimited view visible through use
18300 and renamings. In addition, at the point in which the error
18301 is reported, we add the backslash to the text of the error
18302 to ensure that it is reported as a single error message.
18303 Use new // insertion for some continuation messages
18304 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18305 to create implicit with_clause for parent unit mentioned in original
18306 limited_with_clause.
18307 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18308 unit is a child unit. For ASIS queries.
18309 (Analyze_Subunit): If the subunit appears within a child unit, make all
18310 ancestor child units directly visible again.

18325 a formal object declaration with an access definition or a subtype mark
18326 with a null exclusion.
18327 (P_Generic_Association): Handle association with box, and others_choice
18328 with box, to support Ada 2005 partially parametrized formal packages.
18330 2006-10-31 Robert Dewar <dewar@adacore.com>
18331 Javier Miranda <miranda@adacore.com>
18333 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18334 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18335 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18336 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18337 private extensions.
18338 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18339 to P_Interface_Type_Definition.
18340 (P_Interface_Type_Definition): Addition of one formal to report an error
18341 if the reserved word abstract has been previously found.
18342 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18343 object renaming declaration with an access definition or subtype mark
18344 with a possible null exclusion.
18346 * par-ch9.adb: Minor error msg fix
18348 * par-load.adb: Add missing continuation mark to error msg

18363 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18366 2006-10-31 Vincent Celier <celier@adacore.com>
18368 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18369 on VMS, change "__" to '.' before checking the name.
18370 (Record_Ada_Source): Always add the source file name in the list of
18371 of sources, even if it is not the first time, as it is for another
18373 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18374 dot, instead of replacing only the first '_'.
18376 * prj-part.adb (Parse): Convert project file path to canonical form
18378 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18379 extended, the project id of the project extending it is recorded in its
18380 data, even when it has already been processed as an imported project.
18382 2006-10-31 Robert Dewar <dewar@adacore.com>
18384 * repinfo.adb (List_Entities): Don't list entities from renaming
18387 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18388 Robert Dewar <dewar@adacore.com>
18390 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18391 only a restriction warning is active for the given restriction. This is
18392 desirable because we do not want to modify code in the case where only
18394 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18395 causes overriding of real restrictions.
18396 Take advantage of new No_Restrictions constant.
18398 * raise.h: (__gnat_set_globals): Change profile.
18400 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18402 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18405 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18406 Move all the entities in obsolete package System.PolyORB_Interface to
18407 System.Partition_Interface.

18423 Gary Dismukes <dismukes@adacore.com>
18425 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18426 properly an attempt to apply Unchecked_Access to a protected operation.
18427 (OK_Self_Reference): New subprogram to check the legality of an access
18428 attribute whose prefix is the type of an enclosing aggregate.
18429 Generalizes previous mechanism to handle attribute references nested
18430 arbitrarily deep within the aggregate.
18431 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18432 can appear in an aggregate if this is a default-initialized aggregate
18433 for a self-referential type.
18434 (Resolve_Attribute, case Access): Ditto.
18435 Add support for new implementation defined attribute Stub_Type.
18436 (Eval_Attribute, case Attribute_Stub_Type): New case.
18437 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18438 (Stream_Attribute_Available): Implement using new subprogram from
18439 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18440 Has_Specified_Stream_Attribute flag.
18441 Disallow Storage_Size and Storage_Pool for access to subprogram
18442 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18443 access types of return subtypes in extended return statements. Remove
18444 accessibility checks on anonymous access types when Unchecked_Access is
18446 (Analyze_Attribute): Add support for the use of 'Class to convert
18447 a class-wide interface to a tagged type.
18448 Add support for the attribute Priority.
18449 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18450 whether the designated type is discriminated with a constrained partial
18451 view and require static matching in that case.
18452 Add local variable Des_Btyp. The Designated_Type
18453 of an access to incomplete subtype is either its non-limited view if
18454 coming from a limited with or its etype if regular incomplete subtype.
18456 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18457 Fix predicate to identify and allow cases of (expander-generated)
18458 references to tag of designated object of a RACW.
18459 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18460 non-static, and therefore cannot appear as a primary in a preelaborable
18462 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18463 Has_Read_Write_Attributes.
18464 (Has_Read_Write_Attributes): Reimplement in termes of
18465 Has_Stream_Attribute_Definition.
18466 (Missing_Read_Write_Attributes): When checking component types in a
18467 record, unconditionally call Missing_Read_Write_Attributes recursively
18468 (remove guard checking for Is_Record_Type / Is_Access_Type).
18470 2006-10-31 Robert Dewar <dewar@adacore.com>
18472 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18473 useless assignments here and conditionalize it on absence of exception
18475 (Analyze_Exception_Handlers): Small code reorganization of error
18476 detection code, for new handling of formal packages.
18478 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18479 Hristian Kirtchev <kirtchev@adacore.com>
18481 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18482 that has been constant-folded, preserve information of original tree,
18484 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18485 generated private extension declaration if the formal derived type is
18486 synchronized. Carry synchronized present over to the generated private
18488 (Validate_Derived_Type_Instance): Ensure that the actual of a
18489 synchronized formal derived type is a synchronized tagged type.
18490 (Instantiate_Formal_Package): When creating the instantiation used to
18491 validate the actual package of a formal declared without a box, check
18492 whether the formal itself depends on a prior actual.
18493 (Instantiate_Formal_Subprogram): Create new entities for the defining
18494 identifiers of the formals in the renaming declaration, for ASIS use.
18495 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18496 a renaming declaration or a subtype declaration for an actual in an
18497 instance, capture location information of declaration in generic, for
18499 (Instantiate_Formal_Package): Add comments on needed additional tests.
18500 AI-317 (partial parametrization) is fully implemented.
18501 (Validate_Private_Type_Instance): Add check for actual which
18502 must have preelaborable initialization
18503 Use new // insertion for some continuation messages
18504 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18505 Default_Expression. Add type retrieval when the declaration has an
18506 access definition. Update premature usage of incomplete type check.
18507 (Check_Access_Definition): New subsidiary routine. Check whether the
18508 current compilation version is Ada 05 and the supplied node has an
18510 (Instantiate object): Alphabetize local variables. Handle the creation
18511 of new renaming declarations with respect to the kind of definition
18512 used - either an access definition or a subtype mark. Guard against
18513 unnecessary error message in the context of anonymous access types after
18514 they have been resolved. Add check for required null exclusion in a
18515 formal object declaration.
18516 (Switch_View): A private subtype of a non-private type needs to be
18517 switched (the base type can have been switched without its private
18518 dependents because of the last branch of Check_Private_View.
18519 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18521 (Instantiate_Type): Emit an error message whenever a class-wide type of
18522 a tagged incomplete type is used as a generic actual.
18523 (Find_Actual_Type): Extend routine to handle a component type in a child
18524 unit that is imported from a formal package in a parent.
18525 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18526 agree on constrainedness, rather than checking against ultimate ancestor
18527 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18528 generic body, for navigation purposes.
18530 2006-10-31 Robert Dewar <dewar@adacore.com>
18531 Thomas Quinot <quinot@adacore.com>
18533 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18535 (New_Stream_Subprogram): When processing an attribute definition clause
18536 for a stream-oriented subprogram, record an entity node occurring at
18537 the point of clause to use for checking the visibility of the clause,
18538 as defined by 8.3(23) as amended by AI-195.
18539 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18540 New_Stream_Function and New_Stream_Procedure.
18541 (New_Stream_Function, New_Stream_Procedure): Removed.
18542 (Analyze_Attribute_Definition_Clause, case Address): Check new
18543 Alignment_Check check
18545 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18546 Javier Miranda <miranda@adacore.com>
18547 Robert Dewar <dewar@adacore.com>
18549 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18550 generate the same errors compiling under -gnatc.
18551 (Try_Object_Operation): If no candidate interpretation succeeds, but
18552 there is at least one primitive operation with the right name, report
18553 error in call rather than on a malformed selected component.
18554 (Analyze_Selected_Component): If the prefix is an incomplete type from
18555 a limited view, and the full view is available, use the full view to
18556 determine whether this is a prefixed call to a primitive operation.
18557 (Operator_Check): Verify that a candidate interpretation is a binary
18558 operation before checking the type of its second formal.
18559 (Analyze_Call): Add additional warnings for function call contexts not
18561 (Analyze_Allocator): Move the check for "initialization not allowed for
18562 limited types" after analyzing the expression. This is necessary,
18563 because OK_For_Limited_Init looks at the structure of the expression.
18564 Before analysis, we don't necessarily know what sort of expression it
18565 is. For example, we don't know whether F(X) is a function call or an
18566 indexed component; the former is legal in Ada 2005; the latter is not.
18567 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18568 were missing. We also didn't handle qualified expressions. Now also
18569 allow function calls. Use new common routine OK_For_Limited_Init.
18570 (Analyze_Type_Conversion): Do not perform some legality checks in an
18571 instance, because the error message will be redundant or spurious.
18572 (Analyze_Overloaded_Selected_Component): Do not do style check when
18573 setting an entity, since we do not know it is the right entity yet.
18574 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18575 (Analyze_Overloaded_Selected_Component): Same change
18576 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18577 since regular incomplete subtypes are transformed into corresponding
18578 subtypes of their full views.
18579 (Complete_Object_Operation): Treat name of transformed subprogram call
18580 as coming from source, for browsing purposes.
18581 (Try_Primitive_Operation): If formal is an access parameter, compare
18582 with base type of object to determine whether it is a primitive
18584 (Operator_Check): If no interpretation of the operator matches, check
18585 whether a use clause on any candidate might make the operation legal.
18586 (Try_Class_Wide_Operation): Check whether the first parameter is an
18587 access type whose designated type is class-wide.
18589 2006-10-31 Robert Dewar <dewar@adacore.com>
18590 Ed Schonberg <schonberg@adacore.com>
18591 Gary Dismukes <dismukes@adacore.com>

18594 warn on infinite loops.
18595 Add \\ to some continuation messages
18596 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18597 (Process_Bounds): If the bounds are integer literals that result from
18598 constant-folding, and they carry a user-defined type, preserve that type
18599 rather than treating this as an integer range.
18600 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18601 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18602 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18603 left hand side of assignment.
18604 (Analyze_Assignment): Add suport to manage assigments to the attribute
18605 priority of a protected object.
18606 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18607 not just identifiers.
18608 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18609 or AND THEN for possible tracking.
18610 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18611 case of while loops so we can track values in the loop body.
18613 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18614 Hristian Kirtchev <kirtchev@adacore.com>
18615 Bob Duff <duff@adacore.com>
18617 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18618 procedure cannot be a protected operation (it is a basic_declaration,
18619 not a subprogram_declaration).
18620 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18621 Subp. Add logic for entry processing.
18622 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18623 Determine whether an entry or subprogram of a protected or task type
18624 override an inherited primitive of an implemented interface.
18625 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18626 Update the actual used in calls to Check_Overriding_Indicator.
18627 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18628 generate the proper reference to the parent unit, for cross-reference.
18629 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18631 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18632 (Add_Extra_Formal): Revise procedure to allow passing in associated
18633 entity, scope, and name suffix, and handle setting of the new
18634 Extra_Formals field.
18635 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18636 pass new parameters. Add support for adding the new extra access formal
18637 for functions whose calls are treated as build-in-place.
18638 (Analyze_A_Return_Statement): Correct casing in error message.
18639 Move Pop_Scope to after Analyze_Function_Return, because an extended
18640 return statement really is a full-fledged scope. Otherwise, visibility
18641 doesn't work right. Correct use of "\" for continuation messages.
18642 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18643 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18644 the node doesn't get properly marked as analyzed.
18645 (Analyze_Subprogram_Body): If subprogram is a function that returns
18646 an anonymous access type that denotes a task, build a Master Entity
18648 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18649 proper usage of null exclusion in a result definition.
18650 (Process_Formals): Code cleanup and new error message.
18651 (Process_Formals): Detect incorrect application of null exclusion to
18653 (Conforming_Types): Handle conformance between [sub]types and itypes
18654 generated for entities that have null exclusions applied to them.
18655 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18656 base type is an access subtype. This case arrises with null exclusions.
18657 (New_Overloaded_Entity): Do not remove the overriden entity from the
18658 homonym chain if it corresponds with an abstract interface primitive.
18659 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18660 call to the synthesized predicate Is_Incomplete_Type.
18661 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18663 (Analyze_Subprogram_Declaration): Check that abstract interface
18664 primitives are abstract or null.
18665 (Analyze_Subprogram_Specification): Remove previous check for abstract
18666 interfaces because it was not complete.
18667 (Has_Interface_Formals): Removed.
18669 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18670 Javier Miranda <miranda@adacore.com>
18672 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18673 of Analyze_Package_Body, to create Itype references for anonymous
18674 access types created in the package declaration, whose designated types
18675 may have only a limited view.
18676 (Analyze_Package_Specification): For the private part of a nested
18677 package, install private_with_clauses of enclosing compilation unit if
18678 we are in its visible part.
18679 (Declare_Inherited_Private_Subprograms): Complete barrier
18680 to ensure that the primitive operation has an alias to some parent
18681 primitive. This is now required because, after the changes done for the
18682 implementation of abstract interfaces, the contents of the list of
18683 primitives has entities whose alias attribute references entities of
18684 such list of primitives.
18685 (Analyze_Package_Specification): Simplify code that handles parent units
18686 of instances and formal packages.
18687 (Uninstall_Declarations): Check the convention consistency among
18688 primitive overriding operations of a tagged record type.

18697 expected and found set right)
18698 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18699 (Analyze_Generic_Renaming): Same fix
18700 (Use_One_Package): Do not take into account the internal entities of
18701 abstract interfaces during the analysis of entities that are marked
18702 as potentially use-visible.
18703 (Find_Type): Handle the case of an attribute reference for
18704 implementation defined attribute Stub_Type (simply let the analysis of
18705 the attribute reference rewrite it).
18706 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18707 type that appears in a Use_Type clause.
18708 (Analyze_Object_Renaming): Add support for renaming of the Priority
18710 (Find_Type): In Ada 2005, a task type can be used within its own body,
18711 when it appears in an access definition.
18712 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18713 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18714 in a formal object declaration or in a subtype declaration.
18715 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18716 (Check_Null_Exclusion): New local routine to
18717 Analyze_Subprogram_Renaming. Check whether the formals and return
18718 profile of a renamed subprogram have required null exclusions when
18719 their counterparts of the renaming already impose them.
18720 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18721 Determine whether an entity is inside a generic scope.
18722 (In_Open_Scope): First pass of documentation update.
18723 (Find_Expanded_Name): Add support for shadow entities associated with
18724 limited withed packages. This is required to handle nested packages.
18725 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18726 that makes a renaming of a limited withed package illegal.

18731 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18732 Check_Overriding_Indicator.
18733 (Analyze_Task_Definition): Ditto.
18734 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18735 (Check_Overriding_Indicator): To find overridden interface operation,
18736 examine only homonyms that have an explicit subprogram declaration, not
18737 inherited operations created by an unrelated type derivation.
18738 (Check_Overriding_Indicator): When checking for the presence of "null"
18739 in a procedure, ensure that the queried node is a procedure
18741 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18742 type when the formal is an access to variable.
18743 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18744 (Analyze_Task_Type): Same addition
18745 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18753 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18754 inherited from an interface ancestor by another interface in the
18755 context of an instance as 'late'.
18756 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18757 of a call to a function that dispatches on access result.
18758 (Check_Dispatching_Operation): In case of late overriding of a primitive
18759 that covers abstract interface subprograms we register it in all the
18760 secondary dispatch tables associated with abstract interfaces.
18761 (Check_Dispatching_Call): Add check that a dispatching call is not made
18762 to a function with a controlling result of a limited type. This is a
18763 current implementation restriction.
18764 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18765 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18766 argument is an interface type that is a generic formal.
18767 (Is_Interface_Subprogram): Removed.
18768 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18769 operation, check the formals to handle the case in which it is
18770 associated with an abstract interface type.
18772 2006-10-31 Robert Dewar <dewar@adacore.com>
18773 Ed Schonberg <schonberg@adacore.com>

18787 Hristian Kirtchev <kirtchev@adacore.com>
18788 Javier Miranda <miranda@adacore.com>
18790 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18791 subprogram type to provide better diagnostics in case of ambiguity.
18792 (Covers): Handle coverage of formal and actual anonymous access types in
18793 the context of generic instantiation.
18794 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18795 abstract interface types; this is required to handle concurrent types
18796 with discriminants and abstract interface types.
18797 (Covers): Include type coverage of both regular incomplete subtypes and
18798 incomplete subtypes of incomplete type visibles through a limited with

18812 qualification from an expression. There are numerous places where this
18813 ought to be used, but we currently only deal properly with zero or one
18815 (In_Instance); The analysis of the actuals in the instantiation of a
18816 child unit is not within an instantiation, even though the parent
18817 instance is on the scope stack.
18818 (Safe_To_Capture_Value): Exclude the case of variables that are
18820 (Check_Obsolescent): Removed
18821 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

19584 abstract interface type, the static analysis is not enough to know if

19586 we must pass the work to the expander to generate the required code to
19587 evaluate the conversion at run-time.
19588 (Resolve_Equality_Op): Do not apply previous

20263 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20264 were not always properly handled previously.
20265 Since we are changing the tree format anyway, also get rid of the
20266 junk obsolete Immediate_Errors flag.
20267 (Tree_Read): Change the way of reading Tree_Version_String - now we
20268 read the version string from the tree even if its length is not the
20269 same as the length of the version string computed from Gnatvsn.
20270 (Search_Directory_Present): New Boolean flag for the compiler.
20271 Define Tree_Version_String as a dynamic string.
20272 (Default_Stack_Size): new variable, used to handle switch -d.
20275 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20276 only for main unit.
20277 Add pragma Ada_2005 (synonym for Ada_05)
20278 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20279 were not always properly handled previously.
20281 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20282 explicit Ada_95 to Ada_2005.
20284 2006-02-13 Javier Miranda <miranda@adacore.com>
20285 Robert Dewar <dewar@adacore.com>
20286 Ed Schonberg <schonberg@adacore.com>
20288 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20289 against errors in the source program: a private types for which the
20290 corresponding full type declaration is missing and pragma CPP_Virtual
20292 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20293 (Is_Known_Null): New flag
20294 (Has_Pragma_Pure): New flag
20295 (No_Return): Present in all entities, set only for procedures
20296 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20297 explicitly declared limited.
20298 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20299 entities. Only used for component marked Is_Tag. If present it stores
20300 the Offset_To_Top function used to provide this value in tagged types
20301 whose ancestor has discriminants.
20303 * exp_ch2.adb: Update status of new Is_Known_Null flag
20305 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20307 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20308 the categorization sense if Is_Pure was set by pragma Pure_Function.
20310 2006-02-13 Quentin Ochem <ochem@adacore.com>
20311 Olivier Hainque <hainque@adacore.com>
20313 * bindusg.adb: Updated documentation for -d and -D switches.
20315 * raise.h (__gnat_set_globals): added new parameter for
20316 Default_Stack_Size.
20318 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20319 (__gnat_handle_vms_condition): Adjust context before raise.
20320 (__gnat_install_handler): Restore the global vector setup for GCC
20321 versions before 3.4, as the frame based circtuitry is not available
20323 (__gnat_set_globals): added a parameter default_stack_size
20324 (__gl_default_stack_size): new variable.
20326 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20328 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20329 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20330 does not exist in the Ada RM.
20331 (Compatible_Int_Bounds): Determine whether two integer range bounds
20332 are of equal length and have the same start and end values.
20333 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20334 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20335 aggregate when it is part of an object declaration.
20336 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20337 constrains discriminants of its parent, add explicitly the discriminant
20338 constraints of the ancestor by retrieving them from the
20339 stored_constraint of the parent.
20341 2006-02-13 Robert Dewar <dewar@adacore.com>
20343 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20344 attribute Mechanism_Code is applied to renamed subprogram, modify
20345 prefix to point to base subprogram.
20346 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20348 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20349 renamed subprograms so that the front-end must replace the prefix
20352 2006-02-13 Javier Miranda <miranda@adacore.com>
20353 Gary Dismukes <dismukes@adacore.com>
20355 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20356 availability of RE_Interface_Tag.
20357 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20358 (Freeze_Record_Type): Do not generate the tables associated with
20359 timed and conditional dispatching calls through synchronized
20360 interfaces if compiling under No_Dispatching_Calls restriction.
20361 When compiling for Ada 2005, for a nonabstract
20362 type with a null extension, call Make_Controlling_Function_Wrappers
20363 and insert the wrapper function declarations and bodies (the latter
20364 being appended as freeze actions).
20365 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20366 predefined primitives associated with timed and conditional
20367 dispatching calls through synchronized interfaces if we are
20368 compiling under No_Dispatching_Calls.
20369 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20370 service is available before generating a call.
20371 (Make_Controlling_Function_Wrappers): New procedure.
20372 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20373 access-to-limited-interfaces because they can be used to reference
20374 tasks that implement such limited interface.
20375 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20376 procedure spec and body of the Offset_To_Top function that is generated
20377 when the parent of a type with discriminants has secondary dispatch
20379 (Init_Secondary_Tags): Handle the case in which the parent of the type
20380 containing secondary dispatch tables has discriminants to generate the
20381 correct arguments to call Set_Offset_To_Top.
20382 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20384 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20385 Add Wide_[Wide_]Expanded_Name.
20386 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20387 the same functionality of Get_Prim_Op_Address but applied to predefined
20388 primitive operations because the pointers to the predefined primitives
20389 are now saved in a separate table.
20390 (Parent_Size): Modified to get access to the separate table of primitive
20391 operations or the parent type.
20392 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20393 functionality of Set_Prim_Op_Address but applied to predefined primitive
20395 (Set_Signature): New subprogram used to store the signature of a DT.
20396 (Displace): If the Offset_To_Top value is not static then call the
20397 function generated by the expander to get such value; otherwise use
20398 the value stored in the table of interfaces.
20399 (Offset_To_Top): The type of the actual has been changed to Address to
20400 give the correct support to tagged types with discriminants. In this
20401 case this value is stored just immediately after the tag field.
20402 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20403 offset_to_top value is static and hence pass this value to the run-time
20404 to store it in the table of interfaces, or else if this value is dynamic
20405 and then pass to the run-time the address of a function that is
20406 generated by the expander to provide this value for each object of the
20409 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20410 (Default_Prim_Op_Count): New entity
20411 (Get_Predefined_Prim_Op_Address): New entity
20412 (Set_Predefined_Prim_Op_Address): New entity
20413 (RE_Set_Signature): New entity
20415 2006-02-13 Thomas Quinot <quinot@adacore.com>
20416 Ed Schonberg <schonberg@adacore.com>
20418 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20419 Make_Adjust_Call done for a newly-allocated object.
20421 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20422 in a subprogram are wrapped in a cleanup block, indicate that the
20423 subprogram contains an inner block with an exception handler.
20424 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20425 Adjust call is for a newly-allocated object. In that case we must not
20426 assume that the finalization list chain pointers are correct (since they
20427 come from a bit-for-bit copy of the original object's pointers) so if
20428 the attach level would otherwise be zero (no change), we set it to 4
20429 instead to cause the pointers to be reset to null.
20431 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20432 reset chain pointers to null.
20434 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20436 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20437 string, and the context requires a loop for the assignment (e.g.
20438 because the left-hand side is packed), generate a unique name for the
20439 temporary that holds the string, to prevent spurious name clashes.
20441 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20442 Javier Miranda <miranda@adacore.com>
20443 Robert Dewar <dewar@adacore.com>
20444 Gary Dismukes <dismukes@adacore.com>
20446 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20447 return unconstrained arrays.
20449 (Expand_Call): An indirect call through an access parameter of a
20450 protected operation is not a protected call.
20451 Add circuit to raise CE in Ada 2005 mode following call
20452 to Raise_Exception.
20453 (Register_DT_Entry): Do nothing if
20454 the run-time does not give support to abstract interfaces.
20455 (Freeze_Subprogram): In case of dispatching operations, do not generate
20456 code to register the operation in the dispatch table if the source
20457 is compiled with No_Dispatching_Calls.
20458 (Register_Predefined_DT_Entry): Generate code that calls the new
20459 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20460 Set_Prim_Op_Address.
20462 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20463 on array assignments if the right-hand side is a function call that has
20464 been inlined. Check is performed on the assignment in the block.
20465 (Process_Bounds): If bounds and range are overloaded, apply preference
20466 rule for root operations to disambiguate, and diagnose true ambiguity.
20467 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20468 a tag-indeterminate right-hand side even when Expander_Active is True.
20469 Needed to ensure that dispatching calls to T'Input are allowed and
20470 get the tag of the target class-wide object.
20472 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20473 an inherited primitive operation that already overrides several
20474 abstract interface primitives. For transitivity, the new entity must
20475 also override all the abstract interface primitives covered by the
20476 inherited overriden primitive.
20477 Emit warning if new entity differs from homograph in same scope only in
20478 that one has an access parameter and the other one has a parameter of
20479 a general access type with the same designated type, at the same
20480 position in the signature.
20481 (Make_Inequality_Operator): Use source locations of parameters and
20482 subtype marks from corresponding equality operator when creating the
20483 tree structure for the implicit declaration of "/=". This does not
20484 change anything in behaviour except that the decoration of the
20485 components of the subtree created for "/=" allows ASIS to get the
20486 string images of the corresponding identifiers.
20487 (Analyze_Return_Statement): Remove '!' in warning message.
20488 (Check_Statement_Sequence): Likewise.
20489 (Analyze_Subprogram_Body): For an access parameter whose designated type
20490 is an incomplete type imported through a limited_with clause, use the
20491 type of the corresponding formal in the body.
20492 (Check_Returns): Implicit return in No_Return procedure now raises
20493 Program_Error with a compile time warning, instead of beging illegal.
20494 (Has_Single_Return): Function returning unconstrained type cannot be
20495 inlined if expression in unique return statement is not an identifier.
20496 (Build_Body_To_Inline): It is possible to inline a function call that
20497 returns an unconstrained type if all return statements in the function
20498 return the same local variable. Subsidiary procedure Has_Single_Return
20499 verifies that the body conforms to this restriction.
20501 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20502 same type, and one of them is of an anonymous access type, convert
20503 the other operand to it, so that this is a valid binary operation for
20505 (Resolve_Type_Conversion): Handle subtypes of protected types and
20506 task types when accessing to the corresponding record type.
20507 (Resolve_Allocator): Add '\' in 2-line warning message.
20508 Remove '!' in warning message.
20509 (Resolve_Call): Add '\' in 2-line warning message.
20510 (Valid_Conversion): Likewise.
20511 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20512 resulting type may be an access type with an implicit dereference.
20513 Obtain the proper component from the designated type.
20514 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20515 given by an expanded name with prefix Standard, when the operands are
20516 of an anonymous access type.
20517 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20518 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20519 prefix of the expression is not of an incomplete type. Allows full
20520 diagnoses of all semantic errors.
20521 (Resolve_Actuals): If the actual is an allocator whose directly
20522 designated type is a class-wide interface we build an anonymous
20523 access type to use it as the type of the allocator. Later, when
20524 the subprogram call is expanded, if the interface has a secondary
20525 dispatch table the expander will add a type conversion to force
20526 the displacement of the pointer.
20527 (Resolve_Call): If a function that returns an unconstrained type is
20528 marked Inlined_Always and inlined, the call will be inlined and does
20529 not require the creation of a transient scope.
20530 (Check_Direct_Boolean_Op): Removed
20531 (Resolve_Comparison_Op): Remove call to above
20532 (Resolve_Equality_Op): Remove call to above
20533 (Resolve_Logical_Op): Inline above, since this is only call.
20534 (Valid_Conversion): Handle properly conversions between arrays of
20535 convertible anonymous access types.
20538 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20539 the literal in an unchecked conversion, because GCC 4.x needs a static
20540 value for a string bound.
20542 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20543 Hristian Kirtchev <kirtchev@adacore.com>
20545 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20546 components of the corresponding record, take into account component
20547 definitions that are access definitions.
20548 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20549 procedure is not considered a dispatching call and will be expanded
20552 2006-02-13 Javier Miranda <miranda@adacore.com>
20554 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20555 controlling argument of the dispatching call is an abstract interface
20556 class-wide type then we use it directly.
20557 Check No_Dispatching_Calls restriction.
20558 (Default_Prim_Op_Position): Remove the code that looks for the last
20559 entity in the list of aliased subprograms. This code was wrong in
20561 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20562 when the source is compiled with the No_Dispatching_Calls restriction.
20563 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20564 if we are compiling with restriction No_Dispatching_Calls.
20565 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20566 subprograms if we are compiling under No_Dispatching_Calls restriction.
20567 (Make_DT): Generate a dispatch table with a single dummy entry if
20568 we are compiling with the No_Dispatching_Calls restriction. In
20569 addition, in this case we don't generate code that calls to the
20570 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20571 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20572 of this subprogram if compiling with the No_Dispatching_Calls
20574 (Expand_Type_Conversion): Instead of using the actual parameter,
20575 the argument passed as parameter to the conversion function was
20576 erroneously referenced by the expander.
20577 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20578 Set_Predefined_Primitive_Op_Address and Set_Signature.
20579 (Expand_Dispatching_Call): Generate call to
20580 Get_Predefined_Prim_Op_Address for predefined primitives.
20581 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20582 predefined primitives.
20583 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20584 primitives we reserve one dummy entry to ensure that the tag does not
20585 point to some memory that is associated with some other object. In
20586 addition, remove all the old code that generated the assignments
20587 associated with the signature of the dispatch table and replace them
20588 by a call to the new subprogram Set_Signature.
20589 (Set_All_DT_Position): Change the algorithm because now we have a
20590 separate dispatch table associated with predefined primitive operations.
20591 (Expand_Interface_Conversion): In case of non-static offset_to_top
20592 add explicit dereference to get access to the object after the call
20593 to displace the pointer to the object.
20594 (Expand_Interface_Thunk): Modify the generation of the actual used
20595 in the calls to the run-time function Offset_To_Top to fulfil its
20597 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20599 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20601 * exp_dist.adb (Copy_Specification): For access parameters, copy
20602 Null_Exclusion flag, which will have been set for stream subprograms
20605 2006-02-13 Pascal Obry <obry@adacore.com>
20607 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20608 previous implementation was using the C runtime spawnve routine but
20609 the corresponding wait was using directly the Win32 API. This was
20610 causing some times a lock when waiting for an event using
20611 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20612 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20613 API fixes this problem.
20615 2006-02-13 Robert Dewar <dewar@adacore.com>
20617 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20620 2006-02-13 Thomas Quinot <quinot@adacore.com>

20624 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20625 array reference that is an explicit dereference, mark the converted
20626 (packed) array reference as analyzed to prevent a forthcoming
20627 reanalysis from resetting its type to the original (non-packed) array
20630 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20631 Javier Miranda <miranda@adacore.com>
20632 Eric Botcazou <ebotcazou@adacore.com>
20634 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20635 Is_Predefined_Primitive_Operation): When
20636 searching for the predefined equality operator, verify that operands
20637 have the same type.
20638 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20639 for the last entity in the list of aliased subprograms. This code
20640 was wrong in case of renamings.
20641 (Set_Renamed_Subprogram): New procedure
20642 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20643 Exp_Type constant computed when entering this subprogram.
20644 (Known_Null): New function
20645 (OK_To_Do_Constant_Replacement): New function
20646 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20647 (Side_Effect_Free): An attribute reference 'Input is not free of
20648 side effect, unlike other attributes that are functions. (from code
20650 (Remove_Side_Effects): Expressions that involve packed arrays or records
20651 are copied at the point of reference, and therefore must be marked as
20652 renamings of objects.
20653 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20654 not a dispatching operation.
20657 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20658 elementary types in all cases.
20660 2006-02-13 Javier Miranda <miranda@adacore.com>
20662 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20663 task types when accessing to the corresponding record type.
20664 Remove '!' in warning message.
20666 2006-02-13 Olivier Hainque <hainque@adacore.com>
20668 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20669 to avoid useless and space inefficient overalignments on targets where
20670 Max_Alignment is larger than 16.
20672 2006-02-13 Pascal Obry <obry@adacore.com>
20674 * g-catiio.adb (Sec_Number): New type used to compute the number of
20675 seconds since 1-1-1970.
20676 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20677 negative numbers (years, months...) it is better to have a Natural here.
20679 (Image) [Number]: Change parameter from Long_Integer to Number.
20680 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20681 overflow for dates past year 2038.
20683 2006-02-13 Matthew Heaney <heaney@adacore.com>
20685 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20688 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20690 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20692 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20693 finalization can occur normally.
20695 2006-02-13 Vincent Celier <celier@adacore.com>
20697 * gnatcmd.adb (Rules_Switches): New table
20698 (Add_To_Rules_Switches): New procedure
20699 (GNATCmd): For command CHECK, put all options following "-rules" in the
20700 Rules_Switches table. Append these -rules switches after the -cargs
20703 2006-02-13 Robert Dewar <dewar@adacore.com>
20705 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20706 These two cases were generating incorrect output, and if this unit
20707 was built with checks on, generated a discriminant mismatch constraint
20710 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20711 Robert Dewar <dewar@adacore.com>
20713 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20714 view is an array type, indicate the component type as well, for
20715 navigation purposes.
20716 (Generate_Reference): Don't consider array ref on LHS to be a case

20718 Do not give Ada 2005 warning except on real reference.
20720 2006-02-13 Vincent Celier <celier@adacore.com>
20722 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20723 main source, add switch -mdebug-main=_ada_ so that the executable can
20724 be debugged by the standard VMS debugger.
20725 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20726 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20727 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20728 of the last source, as the binding and linking phases are never
20730 Set all executable obsolete when rebuilding a library.
20732 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20735 2006-02-13 Javier Miranda <miranda@adacore.com>
20738 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20739 code to improve the error message reported when the program has
20740 declarations of abstract interface types and it is not compiled with
20741 the -gnat05 switch.
20742 (P_Access_Definition): Reorganize the code to improve the error
20743 message reported when the new Ada 2005 syntax for anonymous
20744 access types is used and the program is not compiled with the

20767 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20768 unknown, use the location of the project to report the error.
20769 (When_No_Sources): New global variable
20770 (Report_No_Ada_Sources): New procedure
20771 (Check): New parameter When_No_Sources. Set value of global variable

20774 (Get_Sources_From_File): Ditto
20775 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20778 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20779 Call Prj.Proc.Process with parameter When_No_Sources.
20781 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20782 Call Recursive_Check with parameter When_No_Sources.

20797 When removing nodes (attributes Source_Dirs, Source_Files,
20798 Source_List_File and package Naming), save the comments and attach the
20799 saved comments to the newly created nodes.
20800 Do not add a with clause for the naming package if one already exists.

20808 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20809 aliased entities to look for the overriden abstract interface
20811 (Is_Interface_Subprogram): Complete documentation.
20812 (Check_Dispatching_Operation): Do not generate code to register the
20813 operation in the dispatch table if the source is compiled with
20814 restriction No_Dispatching_Calls.

20816 No_Return procedure with procedure that is not No_Return
20817 (Check_Dispatching_Call): Suppress the check for an abstract operation
20818 when the original node of an actual is a tag-indeterminate attribute
20819 call, since the attribute, which must be 'Input, can never be abstract.
20820 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20821 call to the Input attribute (even when rewritten).
20822 (Propagate_Tag): Augment comment to indicate the possibility of a call
20823 to an Input attribute.
20825 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20835 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20837 2006-02-13 Javier Miranda <miranda@adacore.com>
20839 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20840 handles default-initialized components to keep separate the management
20841 of this feature but also avoid the unrequired resolution and
20842 expansion of components that do not have partially initialized
20844 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20845 (Check_Bounds): Likewise.
20846 (Check_Length): Likewise.
20848 2006-02-13 Javier Miranda <miranda@adacore.com>
20849 Ed Schonberg <schonberg@adacore.com>
20851 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20852 abstract interface type call analyze_and_resolve to expand the type
20853 conversion into the corresponding displacement of the
20854 reference to the base of the object.
20855 (Eval_Attribute, case Width): For systems where IEEE extended precision
20856 is supported, the maximum exponent occupies 4 decimal digits.
20857 (Accessibility_Message): Add '\' in 2-line warning message.
20858 (Resolve_Attribute): Likewise.
20859 (case Attribute_Access): Significantly revise checks
20860 for illegal access-to-subprogram Access attributes to properly enforce
20861 the rules of 3.10.2(32/2).
20862 Diagnose use of current instance with an illegal attribute.
20864 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20866 (Enclosing_Generic_Unit): New function to return a node's innermost
20867 enclosing generic declaration node.
20868 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20869 (Type_Access_Level): The accessibility level of anonymous acccess types
20870 associated with discriminants is that of the current instance of the
20871 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20872 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20873 (Kill_Current_Values_For_Entity): New function
20874 (Enter_Name): Change formal type to Entity_Id
20876 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20877 Ed Schonberg <schonberg@adacore.com>

20880 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20881 Analyze_Compilation_Unit.
20882 Detect and warn on redundant with clauses detected in a package spec
20883 and/or body when -gnatwr is used.
20884 (Analyze_Context): Analyze config pragmas before other items
20885 (Install_Context_Items): Don't analyze config pragmas here
20886 (Install_Limited_Withed_Unit): Set limited entity of package in
20887 with_clause so that cross-reference information or warning messages on
20888 unused packages can be properly generated
20889 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20890 has Error_Posted set. Prevent infinite loops in illegal programs.
20891 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20892 to the point of the error test requiring the current unit to be private.
20893 This ensures that private with clauses are not exempted from the basic
20894 checking for being a descendant of the same library unit parent as a
20895 withed private descendant unit.
20896 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20897 handle private with clauses properly, as well as to account for cases
20898 where the withed unit is a public descendant of a private ancestor
20899 (in which case the current unit must be a descendant of the private
20900 ancestor's parent). The spec comments were updated accordingly. Also,
20901 the old error message in this subprogram was replaced with error
20902 messages that mirror the errors tested and reported by
20903 Check_Private_Child_Unit.
20904 Parameter and variable names improved for readability.
20905 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20906 private as the precondition for calling
20907 Check_Private_Limited_Withed_Unit since that subprogram has been
20908 revised to test public units as well as private units.

20913 Javier Miranda <miranda@adacore.com>
20915 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20916 that Scope_Stack.First = 1.
20917 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20918 were not always properly handled previously.
20919 (Formal_Entity): Complete rewrite, to handle properly some complex case
20920 with multiple levels of parametrization by formal packages.
20921 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20922 to the corresponding derived type declaration for proper semantics.
20924 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20925 (Check_Component): Enforce restriction on components of
20926 unchecked_unions: a component in a variant cannot contain tasks or
20928 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20930 Add pragma Ada_2005 (synonym for Ada_05)
20931 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20932 were not always properly handled previously.
20933 Document that pragma Propagate_Exceptions has no effect
20934 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20935 (Set_Convention_From_Pragma): Check that if a convention is
20936 specified for a dispatching operation, then it must be
20937 consistent with the existing convention for the operation.
20938 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20939 longer required to specify an vtable-ptr component in the record. For
20940 compatibility reasons we leave the support for the previous definition.
20941 (Analyze_Pragma, case No_Return): Allow multiple arguments
20943 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20944 non-overrideen inherited operation with a controlling result as
20945 illegal only its implicit declaration comes from the derived type
20946 declaration of its result's type.
20947 (Check_Possible_Deferred_Completion): Relocate the object definition
20948 node of the subtype indication of a deferred constant completion rather
20949 than directly analyzing it. The analysis of the generated subtype will
20950 correctly decorate the GNAT tree.
20951 (Record_Type_Declaration): Check whether this is a declaration for a
20952 limited derived record before analyzing components.
20953 (Analyze_Component_Declaration): Diagnose record types not explicitly
20954 declared limited when a component has a limited type.
20955 (Build_Derived_Record_Type): Code reorganization to check if some of
20956 the inherited subprograms of a tagged type cover interface primitives.
20957 This check was missing in case of a full-type associated with a private
20959 (Constant_Redeclaration): Check that the subtypes of the partial and the
20960 full view of a constrained deferred constant statically match.
20961 (Mentions_T): A reference to the current type in an anonymous access
20962 component declaration must be an entity name.
20963 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20964 class_wide type to refer to full type, not to the incomplete one.
20965 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20966 available. Required to give support to the certified run-time.
20967 (Analyze_Component_Declaration): In case of anonymous access components
20968 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20969 (Process_Discriminants): For an access discriminant, use the
20970 discriminant specification as the associated_node_for_itype, to
20971 simplify accessibility checks.
20973 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20974 Javier Miranda <miranda@adacore.com>
20976 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20977 abstract interpretations on an operator, remove interpretations that
20978 yield Address or a type derived from it, if one of the operands is an
20980 (Try_Object_Operation.Try_Primitive_Operation,
20981 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20982 location when creating the new reference to a primitive or class-wide
20983 operation as a part of rewriting a subprogram call.
20984 (Try_Primitive_Operations): If context requires a function, collect all
20985 interpretations after the first match, because there may be primitive
20986 operations of the same type with the same profile and different return
20987 types. From code reading.
20988 (Try_Primitive_Operation): Use the node kind to choose the proper
20989 operation when a function and a procedure have the same parameter
20991 (Complete_Object_Operation): If formal is an access parameter and prefix
20992 is an object, rewrite as an Access reference, to match signature of
20993 primitive operation.
20994 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20995 by an expanded name with prefix Standard, when the operands are of an
20996 anonymous access type.
20997 (Remove_Abstract_Operations): If the operation is abstract because it is
20998 inherited by a user-defined type derived from Address, remove it as
20999 well from the set of candidate interpretations of an overloaded node.
21000 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21003 2006-02-13 Bob Duff <duff@adacore.com>
21005 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21006 redundant use clauses.
21007 In particular, if the scope of two use clauses overlaps, but one is not
21008 entirely included in the other, we should not warn. This can happen
21009 with nested packages.
21010 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21011 reported errors. The bug was reported when the compiler was built
21012 with assertions enabled.
21013 (Find_Type): If the node is a 'Class reference and the prefix is a
21014 synchronized type without a corresponding record, return the type
21017 2006-02-13 Javier Miranda <miranda@adacore.com>
21019 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21020 if this is the full-declaration associated with a private declaration
21021 that implement interfaces, then the private type declaration must be
21023 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21024 as aliased. The use of the 'access attribute is not available for such
21025 object (for this purpose the object should be explicitly marked as
21026 aliased, but being an anonymous type this is not possible).
21028 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21029 Robert Dewar <dewar@adacore.com>
21031 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21032 compilation unit is an elaboration scope.
21033 (Add_Task_Proc): Add '\' in 2-line warning message.
21034 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21036 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21037 Javier Miranda <miranda@adacore.com>
21039 * sem_type.adb (Write_Overloads): Improve display of candidate
21041 (Add_One_Interp): Do not add to the list of interpretations aliased
21042 entities corresponding with an abstract interface type that is an
21043 immediate ancestor of a tagged type; otherwise we have a dummy
21044 conflict between this entity and the aliased entity.
21045 (Disambiguate): The predefined equality on universal_access is not
21046 usable if there is a user-defined equality with the proper signature,
21047 declared in the same declarative part as the designated type.
21048 (Find_Unique_Type): The universal_access equality operator defined under
21049 AI-230 does not cover pool specific access types.
21050 (Covers): If one of the types is a generic actual subtype, check whether
21051 it matches the partial view of the other type.
21053 2006-02-13 Thomas Quinot <quinot@adacore.com>
21055 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21056 line. This is necessary to allow In_Extended_Main_Unit to provide
21057 correct results for itypes while writing out expanded source.
21058 (Close_File): No need to update the source_index_table here since it's
21059 now done for each line.
21061 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21062 Robert Dewar <dewar@adacore.com>
21064 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21065 preserve the source unit where the itype is declared, and prevent a
21067 (Note_Implicit_Run_Time_Call): New procedure
21068 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21071 * sprint.ads: Document use of $ for implicit run time routine call
21073 2006-02-13 Quentin Ochem <ochem@adacore.com>
21075 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21078 2006-02-13 Bob Duff <duff@adacore.com>
21080 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21081 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21082 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21083 raise Constraint_Error.
21085 * s-vallli.adb (Scan_Long_Long_Integer): Call
21086 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21087 do not scan leading blanks and sign twice.
21088 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21089 raise Constraint_Error.
21091 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21092 Scan_Long_Long_Unsigned): Split out most of the processing from
21093 Scan_Long_Long_Unsigned out into
21094 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21095 This prevents scanning leading blanks and sign twice.
21096 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21099 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21100 out most of the processing from Scan_Unsigned out into
21101 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21102 This prevents scanning leading blanks and sign twice.
21104 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21105 use with Modular'Value attribute.
21106 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21304 * a-taster.ads, a-taster.adb: New files.
21306 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21307 link to the version that does nothing. This way the task termination
21308 routine is not executed twice for the environment task when finishing
21309 because of an unhandled exception.
21311 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21312 handler because of an unhandled exception.
21314 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21320 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21321 non-tasking version of the soft link for task termination. We do
21322 nothing since if we are using the non-tasking version it
21323 means that the task termination functionality is not used.
21324 (Null_Finalize_Global_List): Add this null version for the procedure
21325 in charge of finalizing the global list for controlled objects.
21326 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21327 instead for handling run-time termination in a more flexible way.
21328 (Adafinal_NT): This new procedure will take care of finalizing the
21329 global list for controlled objects if needed, but no tasking
21332 * s-tarest.adb (Task_Lock): Do not try to lock again the
21333 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21334 some run-time operations.
21335 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21336 until all nested locks have been released.
21337 (Task_Wrapper): Call the fall-back task termination handler. It
21338 applies to all tasks but the environment task.
21339 (Finalize_Global_Tasks): Add the call for the task termination
21340 procedure for the environment task.
21341 (Task_Wrapper): suppress warnings around declaration of

21345 moved to the Common_ATCB record.
21346 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21347 Common_ATCB record.
21348 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21349 Common_ATCB record.
21351 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21352 Fall_Back_Handler, and Specific_Handler.

21355 defined in Ada.Task_Termination, to avoid circular dependencies.
21356 (Termination_Handler): Redefine this type here, alredy defined in
21357 Ada.Task_Termination, for avoiding circular dependencies.
21358 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21359 for storing task termination handlers. In addition,
21360 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21361 Common_ATCB because it is used by both the regular and the restricted
21363 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21364 Common_ATCB because it is used by both the regular and the restricted
21366 (Common_ATCB): Added a dynamic task analyzer field.
21368 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21369 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

21371 tasks but the environment task.
21372 (Finalize_Global_Tasks): Call the task termination procedure for the
21373 environment task. The call to Finalize_Global_List is now performed
21374 using the soft links mechanism.
21375 (Task_Wrapper): added dynamic stack analysis.
21377 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21378 potentially blocking operations has been moved from
21379 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21380 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21381 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21382 this run-time check.
21384 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21385 of task termination procedure.
21386 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21428 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21429 to the specification because the frontend generates code that uses this
21431 (Set_Interface_Table): Add missing assertion.
21432 Update documentation describing the run-time structure.
21433 (Displace): New subprogram that displaces the pointer to the object
21434 to reference one of its secondary dispatch tables.
21435 (IW_Membership): Modified to use the new table of interfaces.
21436 (Inherit_TSD): Modified to use the new table of interfaces.
21437 (Register_Interface_Tag): Use the additional formal to fill the
21438 contents of the new table of interfaces.
21439 (Set_Interface_Table): New subprogram that stores in the TSD the

21454 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21455 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21456 record component containing the tag of the secondary dispatch table we
21457 have to use the Offset_To_Top run-time function to get this information;
21458 otherwise if the pointer to the base of the object has been displace
21459 we get a wrong value if we use the 'position attribute.
21461 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21462 all the calls to Expand_Interface_Thunk.
21463 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21466 ensure that the interfaces implemented by the ancestors are placed
21467 at the header of the generated list.
21468 (Expand_Interface_Conversion): Handle the case in which the displacement
21469 associated with the interface conversion is not statically known. In
21470 this case we generate a call to the new run-time subprogram Displace.

21472 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21473 Get_Tagged_Kind and Set_Tagged_Kind.

21481 secondary dispatch table respectively of a tagged type.
21483 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

21497 RE_TK_Tagged, RE_TK_Task.
21499 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21500 Init_Secondary_Tags_Internal to allow its use with interface types and
21501 also to generate the code for the new additional actual required
21502 by Set_Offset_To_Top.
21503 (Build_Init_Statements): In case of components associated with abstract
21504 interface types there is no need to generate a call to its IP.
21505 (Freeze_Record_Type): Generate Select Specific Data tables only for
21507 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21508 the bodies and specifications of the predefined primitive operations
21509 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21510 for concurrent types.

21514 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21515 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21516 properly protected objects and attach handler in the case of the
21517 restricted profile.
21518 Move embeded package Select_Expansion_Utilities into a separate external

21530 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21531 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21532 about the use and expansion of SAVE_EXPRs in the various possible
21533 renaming handling cases.
21534 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21535 abusing DECL_FCONTEXT.

21628 the iterator is quitting iteration on parent directory.
21630 2005-12-09 Javier Miranda <miranda@adacore.com>
21632 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21633 and the assignment to a class-wide object, before the assignment we
21634 generate a run-time check to ensure that the tag of the Target is
21635 covered by the tag of the source.

21700 copied component does not have a known static Esize, then reset
21701 the size and positional fields of the new component.
21702 (Analyze_Component_Declaration): A limited component is
21703 legal within a protected type that implements an interface.
21704 (Collect_Interfaces): Do not add to the list the interfaces that
21705 are implemented by the ancestors.
21706 (Derived_Type_Declaration): If the parent of the full-view is an
21707 interface perform a transformation of the tree to ensure that it has
21708 the same parent than the partial-view. This simplifies the job of the
21709 expander in order to generate the correct object layout, and it is
21710 needed because the list of interfaces of the full-view can be given in
21712 (Process_Full_View): The parent of the full-view does not need to be
21713 a descendant of the parent of the partial view if both parents are
21715 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21716 "limited" the parent must be a limited type.

21728 lists of interfaces constitute a set equality. If not, the first
21729 differing interface is returned.
21730 (Process_Full_View): Improve the check for the "no hidden interface"
21731 rule as defined by AI-396.

21790 available user-specified stream attributes on limited parameters to
21791 also test the type directly rather than only its underlying type (for
21792 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21793 attributes are visible at the point of the subprogram declaration.
21794 For Ada 2005, the error message is modified to indicate that the
21795 type's stream attributes must be visible (again, only for -gnat05).

21827 types use the corresponding record type. This was not needed before
21828 the implementation of Ada 2005 synchronized types because
21829 concurrent types were never tagged types in Ada 95.

21957 * socket.c: Add extern int h_errno for rtems since networking header
21958 files are not available at this point in a tool bootstrap. Newlib

21962 Roger Sayle <roger@eyesopen.com>
21965 * misc.c (internal_error_function): Don't use vsprintf to format

21980 can't handle that case.
21982 2005-11-17 Laurent Guerby <laurent@guerby.net>
21985 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22069 checks does not count in the first case, but does in the second).

22075 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22076 elementary types using the operator in standard. It is cleaner not to
22077 modify the programmers intent, especially in the case of floating-point.
22078 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22079 it did not matter because we always rewrote a/=b to not(a=b).
22080 (Expand_Allocator_Expression): For an allocator expression whose nominal
22081 subtype is an unconstrained packed type, convert the expression to its
22082 actual constrained subtype.
22083 Implement warning for <= or >= where < or > not possible
22084 Fix to Vax_Float tests (too early in many routines, causing premature
22085 Vax_Float expansions.

22091 of pragma Suppress (All_Checks)
22092 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22093 a string literal for precise control over warnings.
22094 Avoid raise of pragma in case of unrecognized pragma and just return

22099 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22100 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22102 Include -gnatwx as part of -gnatg (warn on redundant parens)
22103 Allow optional = after -gnatm
22104 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22105 longer sets Elaboration_Checks.
22106 Code to set warning mode moved to Sem_Warn
22107 so that it can be shared by pragma processing.
22109 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22121 * exp_vfpt.adb: Handle /= case
22122 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22131 requirement that Default_Priority be ((Priority'First +
22132 Priority'Last) / 2) by increasing the range of Interrupt_Priority.

22234 we are not defining the type.
22235 <E_Record_Type>: Likewise.
22236 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22237 to get advantage of the new maybe_stabilize_reference interface, to
22238 ensure that what we reference is indeed stabilized instead of relying
22239 on assumptions on what the stabilizer does.
22240 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22241 type imported through a limited_with clause, use its non-limited view.
22242 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22244 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22245 of #if sections + explicit comparisons of convention identifiers.

22247 before early-returning for certain types when code generation is
22249 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22251 that we are not defining.
22252 (elaborate_expression_1): Do not create constants when creating
22253 variables needed by the debug info: the dwarf2 writer considers that
22254 CONST_DECLs is used only to represent enumeration constants, and emits
22256 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22257 object with an address clause into an indirect reference, drop the
22258 initializing expression.

22270 subtype to build an actual type with bounds template.
22271 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22272 is provided by the front-end, use that subtype to compute the size of
22273 the deallocated object.

22280 maybe_stabilize, for common uses without restriction on lvalues and
22281 without need to check for the success indication.
22282 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22283 pass false instead of 0 as the FORCE argument which is a bool.
22284 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22285 attached to a renaming pointer has been properly stabilized, as no such
22286 object is attached otherwise.
22287 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22288 function uses the "target pointer" return mechanism.
22289 Reinstate conversion of the actual to the type of the formal
22290 parameter before any other specific treatment based on the passing
22291 mechanism. This turns out to be necessary in order for PLACEHOLDER
22292 substitution to work properly when the latter type is unconstrained.

22296 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22300 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22301 static output of record constructor if all the components are constant.
22302 (gnat_build_constructor): For a record type, sort the list of field
22303 initializers in increasing bit position order.
22304 Factor common code to build a storage type for an unconstrained object
22305 from a fat or thin pointer type and a constrained object type.
22306 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22307 types variants, and process special cases of VIEW_CONVERT expressions
22308 as their NOP_EXPR counterpart to ensure we get to the
22309 CORRESPONDING_VARs associated with CONST_DECls.
22310 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22311 on the right-hand side.

22318 extracting the object if converting to a type variant.
22319 (create_var_decl): When a variable has an initializer requiring code
22320 generation and we are at the top level, check for a potential violation
22321 of a No_Elaboration_Code restriction.
22322 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22323 SIZE and SIZE_UNIT which we need for later back-annotations.

22328 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22329 main variant, just replace the VIEW_CONVERT_EXPR.

22465 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity

22508 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22509 'Unrestricted_Access, if the designated type is an interface we
22510 add a type conversion to force the displacement of the pointer
22511 to the secondary dispatch table.
22512 Use Universal_Real instead of Long_Long_Float when we need a high
22513 precision float type for the generated code (prevents gratuitous
22514 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22515 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22516 'Terminated for task interface class-wide objects. Generate a call to
22517 the predefined dispatching routine used to retrieve the _task_id from
22518 a task corresponding record.

22547 the return value into its actual subtype in order to help the backend
22548 to return the actual size instead of the maximum. This is another

22576 2005-11-14 Robert Dewar <dewar@adacore.com>
22578 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22598 attribute of the N_Free_Statement.
22599 Generate itype for classwide designated object in both cases of
22600 user-specified storage pool: specific and class-wide, not only in the
22602 Raise CE when trying to set a not null access type object to null.
22603 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22604 an explicit loop, because freeze nodes make its position variable.

22879 In addition some minor reorganization of the code has been done to
22880 leave it more clear.
22881 (Analyze_Type_Declaration): If type has previous incomplete tagged
22882 partial view, inherit properly its primitive operations.

22896 be included in the interface list.
22897 (Access_Definition): If the designated type is an interface that may

22927 Change name Is_Package to Is_Package_Or_Generic_Package
22928 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22934 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22935 not try to rewrite a renamed stream attribute, because the operations
22936 on the type may not have been generated.
22937 Handle properly a renaming_as_body generated for a stream operation
22938 whose default is abstract because the object type itself is abstract.
22939 (Find_Type): If the type is incomplete and appears as the prefix of a
22940 'Class reference, it is tagged, and its list of primitive operations
22941 must be initialized properly.
22942 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22943 private declaration of a parent unit, prior to compiling the private
22944 part of a child unit, find on the scope stack the proper parent entity
22945 on which to link the use clause.

22969 remove address operations.
22970 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22971 statement to inhibit warning.
22972 (Resolve_Unary_Op): Do not produce a warning when
22973 processing an expression of the form -(A mod B)
22974 Use Universal_Real instead of Long_Long_Float when we need a high

22977 (Resolve_Concatenation_Arg): Improve error message when argument is an
22978 ambiguous call to a function that returns an array.
22979 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23954 Hristian Kirtchev <kirtchev@adacore.com>
23955 Javier Miranda <miranda@adacore.com>
23957 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23958 from object notation, the original node is unanalyzed and carries no
23959 semantic information, so that accessiblity checks must be performed on
23960 the type of the actual itself.
23961 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23962 compatibility with Build_Protected_Sub_Specification.
23963 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23969 include the generation of dispatching subprograms when the type
23970 implements at least one interface.
23972 * lib.ads: Extend information in Load_Stack to include whether a given
23973 load comes from a Limited_With_Clause.
23975 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23976 whether a potential circularity is harmless, because it includes units
23977 loaded through a limited_with clause. Extends previous treatment which
23978 did not handle properly arbitrary combinations of limited and
23979 non-limited clauses.
23981 2005-09-01 Nicolas Setton <setton@adacore.com>
23983 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

23996 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23997 fully qualified name, to distinguish instances with the same local name.
23999 * g-souinf.ads (Enclosing_Entity): Document that entity name is now

24011 (Close): Deallocate any existing filter for the concerned connection
24013 2005-09-01 Laurent Pautet <pautet@adacore.com>
24015 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24016 position set is provided, we compute one in order to reduce the maximum
24017 length of the keys. This computation first selects a character
24018 position between 1 and the minimum length of the keys in order to
24019 avoid reducing one of the keys to an empty string.
24020 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24021 does not converge. The initialization procedure now comes with a
24022 maximum number of iterations such that when exceeded, an exception is
24023 raised in Compute. The user can initialize this ratio to another value
24025 Reformating and updated headers.
24027 2005-09-01 Javier Miranda <miranda@adacore.com>
24029 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24030 that given an entity T creates and returns an Itype that duplicates the
24031 contents of T. The returned Itype has the null-exclusion
24032 attribute set to True, and its Etype attribute references T
24033 to keep the association between the two entities.
24034 Update copyright notice
24036 * sem_aggr.adb (Check_Can_Never_Be_Null,
24037 Aggregate_Constraint_Checks, Resolve_Aggregate,
24038 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
24040 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

24058 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24059 instead of Set_Subtype_Mark.

24068 (Set_Result_Definition): New procedure for N_Function_Specifications.
24069 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24070 and N_Function_Specification.
24072 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24073 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.

24095 (Write_ALI): For D lines, on platforms where file names are
24096 case-insensitive, record the file names in lower case.
24098 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24099 Emmanuel Briot <briot@adacore.com>

24128 * snames.h, snames.ads, snames.adb: Introduce entries in
24129 Preset_Names for Name_Disp_Asynchronous_Select,
24130 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24131 Name_Disp_Timed_Select.
24132 New pragma Debug_Policy
24134 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24136 Switch -gnata also sets Debug_Pragmas_Enabled
24138 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24139 handle an explicit -gnata when compiling predefined files.
24141 2005-09-01 Vincent Celier <celier@adacore.com>
24143 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24144 directories of projects that have no Ada sources.
24146 2005-09-01 Robert Dewar <dewar@adacore.com>
24148 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24149 (makes a difference for wide characters)
24151 * widechar.adb, widechar.ads:
24152 Add Wide_Char_Byte_Count feature to count chars vs bytes
24154 2005-09-01 Thomas Quinot <quinot@adacore.com>
24155 Ed Schonberg <schonberg@adacore.com>
24156 Robert Dewar <dewar@adacore.com>
24158 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24159 'Address attribute reference with an overloaded prefix, use the
24160 location of the prefix (not the location of the attribute reference) as
24161 the error location.
24162 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24163 a function renaming thereof, is a valid prefix for 'Size (where it is
24164 intepreted as a function call).
24165 (Statically_Denotes_Entity): New predicate to determine whether the
24166 prefix of an array attribute can be considered static.
24169 (Eval_Attr): Fix failure to evaluate Component_Size for
24170 unconstrained arrays (resulted in wrong value in packed case, since
24171 back end cannot handle this case)
24173 2005-09-01 Robert Dewar <dewar@adacore.com>
24175 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24176 error msgs for most common cases.

24179 2005-09-01 Javier Miranda <miranda@adacore.com>
24180 Ed Schonberg <schonberg@adacore.com>
24182 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24183 become local to the whole package.
24184 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24185 the package was already analyzed the new algorithm "replaces" the
24186 real entities by the shadow ones. This is required to ensure that
24187 the order of these entities in the homonym chains does not change;
24188 otherwise we can have undefined references at linking time because
24189 in case of conflicts the external name of the entities will have
24190 a suffix that depends on the order of the entities in the chain.
24191 (Remove_Limited_With_Clause): Complementary code that completes the
24192 new algorithm and replaces the shadow entities by the real ones.
24193 (Install_Limited_Withed_Unit): When unchaining entities before the
24194 installation of the shadow entities, only regular entities of the
24195 public part must be taken into account. This is required to
24196 keep this routine in synch with the work done by Remove_Limited_
24198 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24199 even if unit is analyzed, because the analysis of the unit is
24200 idempotent in any case, and the limited view of the unit may have to
24201 be installed for proper visibility.
24202 (Expand_Limited_With_Clause): Even if the unit in the implicit
24203 with_clause has been analyzed already, a limited view of the package
24204 must be built for the current context, if it does not exist yet.
24206 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24207 Javier Miranda <miranda@adacore.com>
24208 Gary Dismukes <dismukes@adacore.com>
24210 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24211 defining entity for the instance body, make a new defining identifier
24212 rather than copying the entity of the spec, to prevent accidental
24213 sharing of the entity list.
24214 (Check_Private_View): When exchanging views of private types, build the
24215 list of exchanged views as a stack, to ensure that on exit the exchanges
24216 are undone in the proper order.
24217 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24218 Restore the compilation environment in case of instantiation_error.
24219 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24220 for an anonymous access result.
24221 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24222 (Formal_Entity): Handle properly the case of a formal package that
24223 denotes a generic package renaming.

24227 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24228 clause if the array aggregate is surrounded by parentheses.

24232 Ed Schonberg <schonberg@adacore.com>
24233 Javier Miranda <miranda@adacore.com>
24235 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24237 to check if a type is Constrained in cases related to code generation
24238 (rather than semantic checking) since otherwise we do not generate
24239 similar code for mutable private types depending if their
24240 discriminants are visible or not.
24241 (Check_Abstract_Overriding): Do not complain about failure to override
24242 the primitive operations used in dispatching selects since they will
24243 always be overriden at the freeze point of the type.
24244 (Access_Definition): Separate out handling for resetting the scope
24245 of an anonymous access function result type. Retrieve the scope
24246 of the associated function rather than using Current_Scope, which
24247 does not have a consistent value (depends on whether we're in the
24248 middle of analyzing formal parameters). Add ??? comment about
24249 finding a cleaner way to handle the special cases of scope setting.
24250 (Process_Incomplete_Dependents): A protected operation is never a
24251 dispatching operation (only its wrapper may be).
24252 (Build_Derived_Record_Type): In case of tagged private types that
24253 implement interfaces add derivation of predefined primitive
24255 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24256 by two parameters that are used in case of derivation from abstract
24257 interface types: No_Predefined_Prims is used to avoid the derivation
24258 of predefined primitives from the interface, and Predefined
24259 Prims_Only is used to complete the derivation predefined primitives
24260 in case of private tagged types implementing interfaces.
24261 Fix typo in comments
24262 (Find_Interface_In_Descendant): Protect the frontend against
24263 wrong code with large circularity chains.
24264 (Is_Private_Overriding): Add support for entities overriding interface
24265 subprograms. The test failed because Entities associated with overriden
24266 interface subprograms are always marked as hidden (and used to build
24267 the secondary dispatch table); in this case the overriden entity is
24268 available through the field abstract_interface_alias (cf. override_
24269 dispatching_operation)
24270 (Access_Definition): Set the scope of the type to Current_Scope for the
24271 case of a function with an anonymous access result type.
24272 (Access_Subprogram_Declaration): Handle creation of the type entity for
24273 an access-to-function type with an anonymous access result.
24274 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24275 in handling for N_Access_Function_Definition.
24276 (Analyze_Subtype_Declaration): Modify the text of error message.
24277 (Derived_Type_Declaration): Modify the text of error message.
24278 (Process_Subtype): Modify the text of error message plus cleanup
24279 of one redundant error message.
24280 (Analyze_Component_Declaration): Code cleanup.
24281 (Analyze_Object_Declaration): Code cleanup.
24282 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24283 attribute in case of access types. Code cleanup.
24284 (Array_Type_Declaration): Code cleanup.
24285 (Process_Discriminants): Create the new null-excluding itype
24286 if required. Code cleanup.
24287 (Process_Subtype): Create the new null-excluding itype if
24288 required. Code cleanup.
24289 (Build_Derived_Record_Type): Code cleanup to avoid calling
24290 twice the subprogram derive_subprograms in case of private
24291 types that implement interfaces. In this particular case the
24292 subprogram Complete_Subprograms_Derivation already does the
24293 job associated with the second call.
24295 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24296 conversion to the full view when generating an operation for a
24297 discriminant whose type may currently be private.
24299 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24300 Javier Miranda <miranda@adacore.com>
24302 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24303 V (Obj.F), the rewriting does not involve the indexed component, but
24304 only the selected component itself.
24305 Do not apply the transformation if the analyzed node is an actual of a
24306 call to another subprogram.
24307 (Complete_Object_Operation): Retain the entity of the
24308 dispatching operation in the selector of the rewritten node. The
24309 entity will be used in the expansion of dispatching selects.
24310 (Analyze_One_Call): Improve location of the error message associated
24312 (Analyze_Selected_Component): No need to resolve prefix when it is a
24313 function call, resolution is done when parent node is resolved, as
24315 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24316 when attempting to resolve a call transformed from its object notation.
24317 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24318 of the argument list for each interpretation of the operation.
24319 (Try_Object_Operation): The designated type of an access parameter may
24320 be an incomplete type obtained through a limited_with clause, in which
24321 case the primitive operations of the type are retrieved from its full
24323 (Analyze_Call): If this is an indirect call, and the return type of the
24324 access_to_subprogram is incomplete, use its full view if available.

24327 Gary Dismukes <dismukes@adacore.com>
24329 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24330 access types the null-exclusion and access-to-constant attributes must
24332 (Analyze_Return_Statement): When the result type is an anonymous access
24333 type, apply a conversion of the return expression to the access type
24334 to ensure that appropriate accessibility checks are performed.
24335 (Analyze_Return_Type): For the case of an anonymous access result type,
24336 generate the Itype and set Is_Local_Anonymous_Access on the type.
24337 Add ??? placeholder for check to disallow returning a limited object
24338 in Ada 2005 unless it's an aggregate or a result of a function call.
24339 Change calls from Subtype_Mark to Result_Definition.
24340 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24341 Result_Definition in call to Make_Function_Specification.
24342 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24343 Set_Result_Definition.
24344 (Make_Inequality_Operator): Change formal Subtype_Mark to
24345 Result_Definition in call to Make_Function_Specification.
24346 (Process_Formals): Create the new null-excluding itype if required.
24347 (New_Overloaded_Entity): For an entity overriding an interface primitive
24348 check if the entity also covers other abstract subprograms in the same
24349 scope. This is required to handle the general case, that is, overriding
24350 other interface primitives and overriding abstract subprograms inherited
24351 from some abstract ancestor type.
24352 (New_Overloaded_Entity): For an overriding entity that comes from
24353 source, note the operation that it overrides.
24354 (Check_Conformance, Type_Conformant): Addition of one new formal
24355 to skip controlling formals in the analysis. This is used to
24356 handle overloading of abstract interfaces.
24357 (Base_Types_Match): Add missing case for types imported from
24358 limited-with clauses
24359 (New_Overloaded_Entity): Add barrier to protect the use of
24360 the "alias" attribute.
24362 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24364 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24365 verify that the procedure and the entry are mode conformant.
24366 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24367 as a different operator, which is often a cut-and-paste error.
24369 2005-09-01 Javier Miranda <miranda@adacore.com>
24370 Ed Schonberg <schonberg@adacore.com>
24372 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24373 used in controlling parameters exclude null because it is necessary to
24374 read the tag to dispatch, and null has no tag.
24375 (Override_Dispatching_Operation): If the previous operation is inherited
24376 from an interface, it becomes hidden and does not participate in later
24379 2005-09-01 Javier Miranda <miranda@adacore.com>
24380 Ed Schonberg <schonberg@adacore.com>
24381 Gary Dismukes <dismukes@adacore.com>
24383 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24384 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24385 the expander will generate the corresponding run-time check to evaluate
24387 (Resolve_Call): Check for legal type of procedure name or prefix that
24388 appears as a trigger in a triggering alternative.
24389 (Valid_Conversion): If expression is ambiguous and the context involves
24390 an extension of System, remove System.Address interpretations.
24391 (Resolve_Qualified_Expression): Reject the case of a specific-type
24392 qualification applied to a class-wide argument. Enhance comment
24393 to explain checking of Original_Node.
24394 (Resolve_Type_Conversion): The location of the error message was not
24395 general enough to handle the general case and hence it has been removed.
24396 In addition, this patch improves the text of the message.
24397 (Resolve_Type_Conversion): Add missing support for access to interface
24399 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24400 do not expand if the expression is the actual in a call, because proper
24401 expansion will take place when the call itself is expanded.
24402 (Resolve_Allocator): If the context is an unchecked conversion, the
24403 allocator inherits its storage pool, if any, from the target type of
24406 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24407 Javier Miranda <miranda@adacore.com>
24409 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24410 inherited interface operation that has an implementation, use the
24411 implementation to avoid spurious ambiguities.
24412 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24413 use the Corresponding_Record_Typ attribute to look for the interface
24414 because it is set by the expander (and hence it is not always
24415 available). For this reason we traverse the list of interfaces
24416 (available in the parent of the concurrent type).
24417 (Interface_Present_In_Ancestor): Handle entities from the limited view
24419 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24421 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24422 from the list of required components.
24423 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24424 primitive procedure of a limited interface with a controlling first
24426 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24428 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24429 capture if it is generated in the second operand of a short-circuit
24431 Do not capture values for variables with address clauses.
24432 (Is_Object_Reference): Treat a function call as an object reference only
24433 if its type is not Standard_Void_Type.
24435 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24437 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24438 to a variable that is statically known to be constant.

24452 Add documentation on environment variable syntax for Expand_Path
24454 * gnat_ugn.texi: Update documentation to include mention of -m switches
24455 Document new treatment of wide characters in max line length
24457 Remove -gnatL/-gnatZ switches, no longer used.
24458 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24461 * gnat_rm.texi: Add doc for two argument form of pragma
24462 Float_Representation.
24463 Add documentation for pragma No_Strict_Aliasing

25220 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25221 longer protected objects. They have been replaced by lower-level
25222 suspension objects made up by a mutex and a condition variable (or
25223 their equivalent given a particular OS) plus some internal data to
25224 reflect the state of the suspension object.
25225 (Initialize, Finalize): Add this initialization procedure for
25226 Suspension_Object, which is a controlled type.
25227 (Finalize): Add the finalization procedure for Suspension_Object,
25228 which is a controlled type.
25230 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

25232 VxWorks specific version of this package. Target dependencies
25233 has been moved to System.Task_Primitives.Operations.
25235 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25237 (InitializeCriticalSection, EnterCriticalSection,
25238 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25239 pCriticalSection by an anonymous access type so that we avoid problems
25240 of accessibility to local objects.

25247 set the environment task mask here.
25248 (Current_State): Add this function that returns the state of the
25250 (Set_False): Add this procedure that sets the state of the suspension
25252 (Set_True): Add this procedure that sets the state of the suspension
25253 object to True, releasing the task that was suspended, if any.
25254 (Suspend_Until_True): Add this procedure that blocks the calling task
25255 until the state of the object is True. Program_Error is raised if
25256 another task is already waiting on that suspension object.
25257 (Initialize): Add this procedure for initializing the suspension
25258 object. It initializes the mutex and the condition variable which are
25259 used for synchronization and queuing, and it sets the internal state
25261 (Finalize): Add this procedure for finalizing the suspension object,
25262 destroying the mutex and the condition variable.

25267 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25268 which provides a low-level abstraction (using operating system
25269 primitives) for Ada.Synchronous_Task_Control.
25270 This object is made up by a mutex (for ensuring mutual exclusion), a
25271 condition variable (for queuing threads until the condition is
25272 signaled), a Boolean (State) indicating whether the object is open,
25273 and a Boolean (Waiting) reflecting whether there is a task already
25274 suspended on this object.

25686 access to subprograms must be recursive.
25687 (Is_Unchecked_Conversion): Improve the test that recognizes
25688 instantiations of Unchecked_Conversion, and allows them in bodies that
25689 are to be inlined by the front-end. When the body comes from an

25716 way as a normal component of an anonymous access type.
25717 (Resolve_Allocator): When an allocator's designated type is a class-wide
25718 type, check that the accessibility level of type given in the

25739 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25740 check on possible violation of restriction No_Direct_Boolean_Operators

26044 the "simple_choice" member in a variant record, in accordance with the
26045 description in the package spec: the information output for a constant
26046 should be "S number", not "SS number".

26747 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26750 error messages if expansion has been disabled due to previous
26751 (unrelated) errors).
26753 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26754 is disabled, the entity denoted by the argument is the access type
26755 itself, not an underlying record type, so there is no need to go back
26756 to the Corresponding_Remote_Type.

26766 denotes a type in the class.
26767 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26768 of Name_Generic_Dispatching_Constructor.
26770 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26771 05 unit for AI-260-02).

26785 the case of renaming of stream attributes when the renaming denotes a
26786 generic formal subprogram association for an abstract formal subprogram.
26787 Check that the attribute is a primitive stream attribute (and not
26788 a class-wide stream attribute) and then rewrite the attribute name
26789 as the name of the appropriate compiler-generated stream primitive.

26793 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26801 itype whose parent is controlled and not yet frozen, do not create a
26802 freeze node for the itype if expansion is disabled.
26804 2005-03-29 Vincent Celier <celier@adacore.com>
26806 * make.adb (Gnatmake): Don't fail if the main project file is declared
26807 as having no Ada sources. Do not display message "no sources to
26808 compile" in quiet output.
26810 2005-03-29 Doug Rupp <rupp@adacore.com>
26812 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26828 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26829 rather than proceed ahead using a junk attribute name.
26831 2005-03-29 Vincent Celier <celier@adacore.com>
26833 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26835 * prj-part.adb (Parse_Single_Project): Set the location of a project
26836 on its defining identifier, rather than on the reserved word "project".
26838 * prj-proc.adb (Expression): Adapt to the fact that default of external
26839 references may be string expressions, not always literal strings.
26840 (Recursive_Process): Set Display_Name equal to Name
26841 when Location is No_Location, that is when there is no actual file.
26842 Get the Display_Name of the project from the source, when it is not a
26844 (Process): Use the Display_Name in error messages
26846 * prj-strt.adb (External_Reference): Allow default to be string

27509 Update documentation on Must_Be_Byte_Aligned for new spec
27511 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27512 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27513 uses of the Access_Disp_Table attribute to reference the first dispatch
27514 table associated with a tagged type. As
27515 part of the implementation of abstract interface types,
27516 Access_Disp_Table has been redefined to contain a list of dispatch
27517 tables (rather than a single dispatch table).
27518 Similarly, upgrade all the references to Tag_Component by the
27519 new attribute First_Tag_Component.
27520 (Find_Inherited_TSS): Moved to exp_tss.
27521 Clean up test in Expand_N_Object_Declaration for cases
27522 where we need to do a separate assignment of the initial value.

27524 declaration of a tagged type is an aggregate, no need to generate an
27525 additional tag assignment.

27528 Bit packed array ops are only called if operands are known to be
27530 (Component_Equality): When returning an N_Raise_Program_Error statement,
27531 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27532 expects that only expressions have a bona fide type).
27533 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27534 determine the amount of data to be copied.
27536 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27537 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27564 (Task_Body_Procedure): Removed.
27565 (Set_Task_Body_Procedure): Removed.
27566 These subprogram have been removed because the attribute
27567 Task_Body_Procedure has been moved to the corresponding task type
27568 or task subtype entity to leave a field free to store the list
27569 of interfaces implemented by a task (for AI-345)
27570 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27571 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27572 expression flag Do_Range_Check
27573 (Exception_Junk): Change to Flag7 to accomodate above change
27574 (Box_Present, Default_Name, Specification, Set_Box_Present,
27575 Set_Default_Name, Set_Specification): Expand the expression
27576 "X in N_Formal_Subprogram_Declaration" into the corresponding

27580 "with string" given.
27582 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27585 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27588 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27589 attribute Task_Body_Procedure rather than the old semantic field that
27590 was available in the task_type_declaration node.
27592 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27593 interface type definitions.
27594 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27597 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27598 task type declaration.

27600 protected type declaration.
27602 2005-03-15 Doug Rupp <rupp@adacore.com>
27603 Vincent Celier <celier@adacore.com>
27605 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27606 (Gen_Output_File_C): Likewise.
27607 (Gen_Main_C): Issue #include <stdlib.h> to avoid warning

27611 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27612 is an N_Raise_Constraint_Error node, create a new copy of it without
27613 going through a call to Duplicate_Subexpr.

27626 size of their types.
27627 (gnat_to_gnu_entity, case E_Component): Always look at
27628 Original_Record_Component if Present and not the entity.
27629 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27630 of tagged extension types by not making field for components that are
27632 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27633 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27634 expression to the type of the object when the object is constant.
27635 Reverse defer_debug_incomplete_list before traversing it, so that trees
27636 are processed in the order at which they were added to the list. This
27637 order is important when using the stabs debug format.
27638 If we are deferring the output of debug information, also defer this
27639 output for a function return type.
27640 When adding fields to a record, prevent emitting debug information
27641 for incomplete records, emit the information only when the record is
27643 (components_to_record): New parameter defer_debug.
27644 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27645 (gnat_to_gnu_field_decl): New function.

27647 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27648 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27649 No longer update discriminants to not be a COMPONENT_REF.
27650 (copy_alias_set): Strip padding from input type; also handle
27651 unconstrained arrays properly.
27653 * gigi.h (write_record_type_debug_info): New function.
27654 Convert to use ANSI-style prototypes. Remove unused
27655 declarations for emit_stack_check, elab_all_gnat and

27664 (convert) <UNION_TYPE>: Accept slight type variations when
27665 converting to an unchecked union type.
27667 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27668 replace the N_Freeze_Entity with a null statement.
27670 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27671 within a constrained subcomponent of an enclosing record, place the

27674 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27675 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27676 within records; allow them to have freeze nodes if their base types
27679 * exp_util.adb (Remove_Side_Effects): Properly test for
27680 Expansion_Delayed and handle case when it's inside an
27681 N_Qualified_Expression.
27683 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27684 Comes_From_Generic, to recognize accurately that the parent type in a
27685 derived type declaration can be traced back to a formal type, because
27686 it is one or is derived from one, or because its completion is derived
27688 (Constrain_Component_Type): If component comes from source and has no
27689 explicit constraint, no need to constrain in in a subtype of the
27691 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27692 Minor change to propagate Is_Ada_2005 flag
27694 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27695 Expansion_Delayed is False.
27696 (assoc_to_constructor): Ignore fields that have a
27697 Corresponding_Discriminant.
27698 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27699 function returns "by target", dereference the target pointer using the
27700 type of the actual return value.
27701 <all>: Be prepared for a null gnu_result.
27702 (processed_inline_subprograms): Check flag_really_no_inline

27713 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27714 Must_Be_Byte_Aligned for cases where we do not need to use a
27715 System.Pack_nn unit.
27717 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27719 Needed now that we do some processing for IN parameters as well. This
27720 may well fix some unrelated errors.
27721 (Expand_Call): Handle case of unaligned objects (in particular those
27722 that come from packed arrays).
27723 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27724 renamed entity is an inherited operation, re-expand the call using the
27725 original operation, which is the one to call.
27726 Detect attempt to inline parameterless recursive subprogram.
27727 (Represented_As_Scalar): Fix to work properly with private types
27728 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27729 accurate estimate. Yields True in far fewer cases than before,
27730 improving the quality of code that depends on this test.
27732 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27733 over both visible and private declarations to remove them from tree,
27734 and mark subprograms declared in package as eliminated, to prevent
27735 spurious use in subsequent compilation of generic units in the context.
27737 * exp_util.ads: Minor cleanup in variable names
27739 * sem_eval.ads, sem_eval.adb: Minor reformatting
27740 (Compile_Time_Known_Bounds): New function

27744 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27745 determining whether an unchecked conversion is needed for the argument
27746 of an initialization call.
27748 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27750 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27751 that appears in the instantiation rather than the internal subtype
27752 generated in the wrapper package, to avoid anomalies in gigi when the
27753 target is derived from a private type whose full view is an access type.
27755 2005-03-15 Robert Dewar <dewar@adacore.com>
27757 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27759 Add documentation to replace the use of this flag
27760 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27763 2005-03-15 Thomas Quinot <quinot@adacore.com>
27765 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27766 here from exp_attr so it can be shared between exp_attr and exp_dist.
27767 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27768 all TSS names, not a subset thereof, and the previous name introduced
27769 an unnecessarily confusion that a distinction might exist between
27770 "OK" TSS names and some "not OK" TSS names.
27772 2005-03-15 Doug Rupp <rupp@adacore.com>
27774 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27777 2005-03-15 Pascal Obry <obry@adacore.com>
27778 Eric Botcazou <ebotcazou@adacore.com>
27782 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27783 when IN_RTS. This is to work around a bootstrap path problem.
27785 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27786 table and pass it to __gnat_install_SEH_handler().
27787 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27789 * lang.opt: Fix specification of -fRTS=.

27793 Vincent Celier <celier@adacore.com>
27794 Arnaud Charlet <charlet@adacore.com>
27797 This change works fine when gnatlib is built from the gcc directory,
27798 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27799 is not passed to ada/Makefile.in, so more work is needed by a
27800 Makefile/configure expert.
27802 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27803 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27804 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27806 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.

27811 2005-03-15 Robert Dewar <dewar@adacore.com>
27813 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27815 * impunit.adb: Add GNAT.UTF_32
27817 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27819 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27820 now uses GNAT.UTF_32).
27822 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27823 capabilities for categorizing characters using Unicode categories
27825 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27827 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27828 instantiation that has been rewritten as a package body, retrieve spec
27829 to generate proper name for implicit_with_clause.
27830 (Install_Parents): Recognize a parent that is an instantiation but has
27831 been rewritten as a package declaration during analysis.
27833 2005-03-15 Javier Miranda <miranda@adacore.com>
27834 Ed Schonberg <schonberg@adacore.com>
27836 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27837 parameter reported some error we immediately return. This improves the
27838 behaviour of the frontend in case of errors.
27839 (Install_Parent, Remove_Parent): Introduce new flag
27840 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27841 ancestor of a generic child unit, when the child is being instantiated.
27842 (Inline_Instance_Body): If we are compiling the private
27843 part or the body of a child unit, restore the proper visibility of the
27844 parents after compiling the instance body.
27846 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27847 Javier Miranda <miranda@adacore.com>
27850 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27851 of a private type, in which case it is underlying_type that denotes
27852 the proper task. Also modified to use the new entity attribute
27853 that is directly available in the task type and task subtype entities
27854 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27855 arrays when other dimensions than the first are constrained by
27856 discriminants of an enclosing record.
27857 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27858 a combination of indexed and selected components, find ultimate entity
27859 and generate the appropriate reference for it, to suppress spurious
27861 (Note_Possible_Modification): If an entity name has no entity, return.
27862 (Is_Variable): A function call never denotes a variable.
27863 (Requires_Transient_Scope): For record types, recurse only on
27864 components, not on internal subtypes that may have been generated for
27865 constrained components.

27869 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27870 Eliminated as candidates for resolution. Both efficient, and avoids
27871 anomalies with operators declared in deleted code.
27872 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27873 expansion is disabled (as when compiling a generic) to prevent spurious
27874 warnings on prefixes of selected components.
27876 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27878 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27879 attached to a list before checking whether it appears in the private
27880 declarations of the current package.
27881 (Make_Inequality_Operator): Insert declaration in proper declarative
27882 list rather than just setting the Parent field, so that
27883 Is_Private_Declaration can handle it properly.
27885 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27887 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27888 a renaming a body, check that the renamed subprogram in not intrinsic.
27889 (Find_Direct_Name): If several use_visible entities hide
27890 each other, and the context is a predefined file compiled through
27891 rtsfind, keep only the entity that comes from a predefined file.
27893 2005-03-15 Geert Bosch <bosch@adacore.com>
27895 * s-fatgen.adb (Valid): Extend special exceptions to account for long

28290 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28291 Remove ["0A"] from comment, since it can look like a line terminator.
28292 Currently we don't permit this, but this is under discussion by the
28293 ARG, and it is easy enough to use a different example.
28295 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28296 handling UTF-32 encoding for wide wide character.
28297 Implement new brackets coding ["hhhhhhhh"]

28300 * ttypes.ads: Add definition of Standard_Wide_Wide_Character_Size
28302 * types.h, types.ads, types.adb: Wide_Wide_Character now has full 31
28303 bit range Add full UTF-32 support.
28304 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28305 notify that constraint error will be raised at run-time
28306 because a null value is assigned to a null-excluding object.
28307 Remove some obsolete declarations and make Char_Code
28310 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28311 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28312 Rcheck subprograms.
28314 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28315 wrong null-exclusion value by a warning message.
28316 (Enable_Range_Check): Do range check if the prefix is an
28317 explicit dereference whose designated object is an unconstrained array.
28318 Current algorithm for removing duplicate checks is over-eager in this
28321 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
28322 null-exclusion value by a warning message
28324 * atree.h, atree.ads, atree.adb: Remove Char_Code field support
28325 completely. Add support for Uint2 field
28327 sem_ch2.adb, exp_ch11.adb, exp_dbug.adb,

28330 * exp_util.adb (Insert_Actions): Replace
28331 N_Formal_Subprogram_Declaration by
28332 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
28333 Char_Literal_Value field is now a Uint.
28335 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28336 defined for subprogram renaming declarations. When set, the field
28337 indicates the defining entity of a corresponding formal subprogram
28338 when the renaming corresponds to a formal subprogram association in an
28340 (Set_Corresponding_Formal_Spec): New procedure to return
28341 Corresponding_Formal_Spec field.
28342 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28343 (which is now a subtype).
28344 Char_Literal_Value field is now a Uint
28346 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28347 pointer to the base of the dispatch table.
28348 Minor changes to comments.
28349 (Controlling_Type): New function for determining the tagged type
28350 associated with a tagged primitive subprogram.
28351 (Expand_Dispatching_Call): Add support for a controlling actual that is
28352 directly a value of type Ada.Tag rather than a tagged object.
28354 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28355 describing the new layout.
28356 (Dispatch_Table): The expander computes the actual array size, allocates
28357 the Dispatch_Table record accordingly, and generates code that displaces
28358 the base of the record after the Typeinfo_Ptr component. The access to
28359 these components is done by means of local functions.
28360 (Offset_To_Top): New function.
28361 (Typeinfo_Ptr): New function.
28362 (Get_TSD): Modified to access the new position of the TSD.
28363 (Set_TSD): Modified to save the TSD in its new position.
28365 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28366 case of formal abstract subprograms. Add check and message for -gnat05.
28369 * sem_ch12.adb: Add with and use for Sem_Disp.

28373 N_Formal_Subtype_Declaration (which is now a subtype).
28374 (Analyze_Formal_Subprogram): Add handling for
28375 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28376 dispatching, setting the controlling status of the formal parameters
28377 and result, and issuing an error if there is no controlling type for
28378 the formal subprogram.
28379 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28380 which is an unclean use of that field, we set the new field
28381 Corresponding_Formal_Spec to make the formal subprogram available to
28382 processing in Analyze_Subprogram_Declaration.
28383 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28384 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28385 Constrained, so that it is is does not statically match its anonymous
28388 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28389 abstract formal subprograms in error check for functions returning
28390 abstract types. Set scope of new designator for
28391 a parameterless subprogram, so that it is available when checking the
28392 body for nested subprograms, before full analysis of said body.
28393 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28394 subprogram only if inner one comes from source.
28395 (Analyze_Function_Call): If the call is given in object notation, the
28396 analysis of the name rewrites the node and analyzes it with the proper
28397 argument list. After analyzing the name, if the call has been rewritten
28398 and the result type is set, no further analysis is needed.
28399 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28400 mark in function specification, in a context where the formals are
28401 visible and hide outer homographs.
28403 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28404 as the tagged type for the cases of abstract formal subprograms and
28405 renamings of those. Clean up spec comments.
28406 (Check_Dispatching_Context): Add error message to indicate "abstract
28407 procedure", covering the case of a call to a formal abstract procedure
28408 that has statically tagged operands.
28409 (Check_Dispatching_Call): Check for the case of an actual given by
28410 a tag-indeterminate function call whose type is an ancestor of the
28411 containing call's associated tagged type. This situation can occur
28412 for inherited primitives with function defaults. In this case we
28413 use the tagged type's tag directly as the controlling argument for
28415 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28417 * sprint.adb (Sprint_Node_Actual): Split
28418 N_Formal_Subprogram_Declaration into two alternatives for the new
28419 cases N_Formal_Abstract_Subprogram_Declaration and

28490 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28494 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28495 on the field if Pragma Component_Alignment (Storage_Unit).
28496 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28497 side-effects as if it were a constant; also make SAVE_EXPR to protect
28499 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28501 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28502 (components_to_record): Test it.

28515 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28517 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28518 component of an array of arrays in an assignment context, and the
28519 aggregate has component associations that require sliding on
28520 assignment, force reanalysis of the aggregate to generate a temporary
28521 before the assignment.
28522 (Must_Slide): Make global to the package, for use in Gen_Assign.
28524 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28526 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28527 unchecked union with no inferable discriminants, return a
28528 Raise_Program_Error node, rather than inserting it at the point the
28530 (Expand_Record_Equality, Component_Equality): Handle properly the case
28531 where some subcomponent is an unchecked union whose generated equality
28532 code raises program error.
28534 2005-02-09 Doug Rupp <rupp@adacore.com>
28536 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28540 Arnaud Charlet <charlet@adacore.com>
28542 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28543 address of the exception registration. The Win32 version of this
28544 routine calls __gnat_install_SEH_handler() to initialize the SEH
28545 (Structured Exception Handling) handler.
28546 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28547 SEH (Structured Exception Handling) now.
28548 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28549 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28550 preprocessor condition protecting the call to the extra eh setup
28551 subprogram, which is only available for the ppc target.
28552 (__gnat_clear_exception_count): replaced reference to
28553 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28555 * seh_init.c: New file.
28557 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28558 (GNATBIND_OBJS): Idem.
28560 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28561 routine takes a new parameter (a pointer to the exception registration
28562 for the SEH (Structured Exception Handling) support.
28564 * raise.h: (__gnat_install_SEH_handler): New prototype.
28565 Update copyright notice.
28567 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28568 record and initialize it by calling __gnat_install_SEH_handler.
28570 2005-02-09 Vincent Celier <celier@adacore.com>
28572 * make.adb (Gnatmake): Do not fail when the main project has no object

28578 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28579 [VMS]: Add translations for g-enblsp.adb.
28581 * s-asthan-vms.adb: Removed.
28582 * s-asthan-vms-alpha.adb: Added.
28584 2005-02-09 Pascal Obry <obry@adacore.com>
28586 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.

28589 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28592 * Makefile.in: Link all gnat tools with -static-libgcc, since
28593 -shared-libgcc is now used by default on some systems (e.g. linux with
28595 Remove references to Makefile.prolog/generic, no longer used.
28597 2005-02-09 Vincent Celier <celier@adacore.com>
28599 * prj-makr.adb (Process_Directory): Put file name in canonical case
28600 before matching against the patterns.
28601 If gnatname has been invoked as <prefix>-gnatname
28602 then invoke the compiler as <prefix>-gcc, not just "gcc".
28604 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28606 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28607 with expansion disabled. The actual subtype is needed among other
28608 places when the selected component appears in the context of a loop
28609 bound, and denotes a packed array.
28610 (Operator_Check): Always use the first subtype in the
28611 error message, to avoid the appearance of internal base types.
28612 (Transform_Object_Operation): Copy each actual in full
28613 to the parameter associations of the constructed call, rather than
28614 using the shallow copy mechanism of New_Copy_List. This ensures that
28615 the chaining of named associations is done properly.
28616 (Complete_Object_Operation): Rewrite node, rather than
28617 replacing it, so that we can trace back to the original selected
28620 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28621 and calls that use object notation, if the called function is not
28622 declared in a withed unit, place the elaboration constraint on the
28623 unit in the context that makes the function accessible.
28624 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28625 imposes an elaboration constraint between two packages.
28627 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28629 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28630 views of a private type after handling its private dependents, to
28631 maintain proper stack discipline between entry and exit from the
28634 2005-02-09 Cyrille Comar <comar@adacore.com>
28636 * s-finimp.adb: (Finalize_List): Optimize in the no-abort case.

28647 recursion warnings when compiled with -gnatdm.
28649 2005-02-09 Robert Dewar <dewar@adacore.com>
28651 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28652 Slight fix to documentation of -gnaty with no parameters
28654 * xr_tabls.ads: Add ??? comment for missing overall comment
28656 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28657 we now use by default.
28659 * xsnames.adb: Adjust end of file test to look for five space followed
28660 by '#' instead of six spaces. The format of xsnames.adb was modified
28661 in the last update.
28663 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28666 * clean.adb: Minor reformatting.
28668 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28669 gnatname.adb: Minor reformatting
28670 Add 2005 to copyright output when utility is run
28672 * csets.adb: Eliminate obsolete comment
28674 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28677 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28679 2005-02-09 Sergey Rybin <rybin@adacore.com>
28681 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28682 the difference between compact and incompact layout and add the record
28683 representation clause to the example illustrating different layouts.
28684 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28685 component clauses").
28687 2005-02-09 Florian Villoing <villoing@adacore.com>
28689 * gnat_ugn.texi: Fix typos.
28690 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28692 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28693 in the generated documentation.
28695 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28697 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
28699 Update linker wrapper when linking with non GNU C++.

28704 Document the procedure to debug the DllMain routine on Windows.
28705 Add note about -funwind-tables and mixed Ada and C/C++ programming in
28707 Document new BIND qualifer /RETURN_CODES=VMS.

28727 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
28728 from the VxWorks kernel) that is needed for getting the active
28729 priority of the different tasks.
28731 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28732 Use a pragma Elaborate_Body in the spec file instead.
28733 Noticed by code reading.
28735 2005-02-09 Thomas Quinot <quinot@adacore.com>
28737 * exp_util.ads: Minor correction in comment.
28739 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28741 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28742 since this procedure is now too complex to be worth inlining.
28744 2005-02-09 Richard Henderson <rth@redhat.com>
28746 * utils.c (gnat_define_builtin): Remove.
28747 (gnat_install_builtins): Use build_common_builtin_nodes.

29162 note that it applies to obsolete GNAT features, which was previously
29163 omitted. Second we contrast the behavior with that of the new
29164 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29165 Preliminary rewriting of GNAT & libraries chapter in order to take

29397 "no bitfield creation", to be used by make_aligning_type. Don't
29398 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29399 fields claimed addressable still have to be bitfields. Use
29400 value_factor_p instead of a raw binop construction to check for the
29401 position's alignment.

29408 Ed Schonberg <schonberg@adacore.com>
29410 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29411 with an implicit dereference as its prefix, use
29412 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29414 prefix is generated, if appropriate.
29416 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29417 dereference is rewritten to an explicit one, generate a reference to
29418 the entity denoted by its prefix using the original prefix node, so

29420 access value, if appropriate.
29422 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29423 emitting 'assigned but never read' warning on a variable on the basis

29437 an external name, to be handled by the back end.
29439 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29440 subprogram which is Imported with convention Intrinsic if an
29441 External_Name argument is specified.
29442 (Process_Import_Or_Interface): Properly diagnose link name argument.
29443 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29468 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29469 PCS-specific part of Add_Stub_Type.

29496 (Generate_Reference): Handle properly a reference to an entry formal,
29497 when an accept statement has a pragma Unreferenced for it.
29499 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29500 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29501 the body, to ensure that warnings are properly emitted for each accept
29502 statement of a given task entry.

29524 (Remove_Next_Debug): Same fix
29526 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29527 maintain back pointers now, though we did not used to, and comments
29529 (Prepend): Remove pragma Inline.
29530 (Remove_Next): Same cleanup
29532 2004-12-07 Thomas Quinot <quinot@adacore.com>
29534 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29535 used to record an implicit dereference as a read operation on its
29536 prefix when operating under -gnatc. Necessary to avoid spurious
29537 'variable assigned but never read' warnings in that mode.
29538 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29539 is a non-overloaded implicit dereference, call the above subprogram to
29540 ensure proper recording of references.
29542 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29544 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29545 to be resolved later as part of Analyze_Iteration_Scheme's call to

29592 2004-12-07 Vincent Celier <celier@adacore.com>
29594 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29595 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29596 and -eit to -ept. Added qualifier
29597 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29599 2004-11-27 Andreas Schwab <schwab@suse.de>
29601 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29603 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29605 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29606 internal implementation unit GNAT.Sockets.Thin,
29607 as their usage for sockets is non-portable (using the read and write
29608 functions from the system runtime library is fine on UNIX but won't
29609 work under Windows).
29611 * mingw32.h: Update copyright notice.
29613 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29665 new Others_Value and All_Others_Value objects.
29666 (struct attrib): Rename "arg" component as "args", since GCC expects a
29667 list of arguments in there.
29669 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29670 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29673 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29674 others_decl and all_others_decl instead of hardcoded dummy addresses
29675 to represent "others" and "all others" choices, which is cleaner and
29676 more flexible with respect to the possible eh pointer encoding policies.
29678 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29679 (process_attributes): Account for the naming change of the "args"
29680 attribute list entry component.
29682 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29683 cumulating attributes for different entities into a single list.
29684 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29685 attributes for the current entity and propagate first subtype
29686 attributes to other subtypes.
29687 <E_Procedure>: Attribute arguments are attr->args and not
29688 attr->arg any more.
29689 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29690 argument provided, as this is what GCC expects. Use NULL_TREE instead
29693 2004-11-18 Robert Dewar <dewar@adacore.com>
29695 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29728 (First_RCI_Subprogram_Id): Document this constant.
29729 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29731 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29732 replaced with calls to Get_Library_Unit_Name_String. Previously there
29733 were several instances of the same code in different locations in the
29734 compiler; this checkin completes the replacement of all of these
29735 instances with calls to a common subprogram.
29736 Minor reformatting.

29769 that the pragmas are properly attached to the tree, and that no
29770 nodes are improperly shared.
29772 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29773 pragmas to Exp_Prag, which is more appropriate.
29774 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29775 check for duplicates Remove use of Is_Psected flag, no longer needed.
29776 Use new Make_String_Literal function with string.
29778 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29779 that are functions return universal values, that have to be converted
29780 to the context type.
29781 Use new Make_String_Literal function with string.
29782 (Get_Stream_Convert_Pragma): New function, replaces the use of
29783 Get_Rep_Pragma, which had to be kludged to work in this case.
29785 * freeze.adb: Use new Has_Rep_Pragma function
29787 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29788 function with string.
29789 Use new Has_Rep_Pragma function.
29791 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29794 2004-11-18 Robert Dewar <dewar@adacore.com>
29796 * errout.ads, errout.adb: (First_Sloc): New function
29798 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29799 check (-gnatyx) instead of being included as a redundant construct
29802 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29803 Style_Check_Order_Subprograms.
29805 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29806 stylesw.adb: Add Style_Check_Xtra_Parens
29808 * usage.adb: Add line for -gnatyx (check extra parens)
29810 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29812 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29813 Robert Dewar <dewar@adacore.com>
29815 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29816 discriminant of a constrained subtype, analyze the copy of the
29817 corresponding constraint, because in some cases it may be only
29818 partially analyzed.
29819 Removes long-lived ??? comments.
29821 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29822 handled controlled or secondary-stack expressions within the
29823 iteration_scheme of a loop.
29825 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29826 bounds that may contain functions calls, to prevent memory leaks when
29827 the bound contains a call to a function that uses the secondary stack.
29828 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29829 generate temporaries for loop bounds that might contain function calls
29830 that require secondary stack and/or finalization actions.
29832 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29833 selected component and the selector is overloadable (not just a
29834 function) treat as function call, Analyze_Call will disambiguate if
29836 (Analyze_Selected_Component): Do not generate an actual subtype for the
29837 selected component if expansion is disabled. The actual subtype is only
29838 needed for constraint checks.
29839 (Analyze_Allocator): If restriction No_Streams is set, then do
29840 not permit objects to be declared of a stream type, or of a
29841 composite type containing a stream.
29843 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29844 No_Streams no longer prohibits with'ing this package.
29846 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29847 discriminants, but the parent base has unknown discriminants, there is
29848 no discriminant constraint to inherit. Such a discrepancy can arise
29849 when the actual for a formal type with unknown discriminants is a
29850 similar private type whose full view has discriminants.
29851 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29852 do not permit objects to be declared of a stream type, or of a
29853 composite type containing a stream.
29855 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29857 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29858 protected operations.
29860 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29861 generated name, it complicates decoding in gdb and hinders debugging
29862 of protected operations.
29863 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29864 flag for the protected entry barrier function.
29865 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29866 flag for the protected entry function.
29868 2004-11-18 Nicolas Setton <setton@adacore.com>
29870 * expect.c: Define __unix__ when __APPLE__ is defined.
29872 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29873 Darwin-specific section.
29875 * lang-specs.h: Change the placement of the %1 marker.
29876 Works around the fact that gcc adds -fPIC by default under Darwin.
29878 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29880 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29881 type of the object with the packed array type, set the Analyzed flag
29882 on the object if it is an entity or simple indexed component, to avoid
29883 spurious type errors.
29885 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29887 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29888 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29889 separate line from the version message.
29891 2004-11-18 Ed Falis <falis@adacore.com>
29893 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29895 (init_float): Eliminate initialization of floating point status for
29896 AE653. The instructions have no effect for vThreads.
29898 2004-11-18 Vincent Celier <celier@adacore.com>
29900 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29901 gnatbind is invoked with -shared.
29903 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29905 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29906 for Detect_Blocking which is redundant with the check done within the
29907 procedure Protected_Single_Entry_Call.
29908 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29909 Detect_Blocking which is redundant with the check done within the
29910 procedure Protected_Single_Entry_Call.
29912 2004-11-18 Vincent Celier <celier@adacore.com>
29914 * makegpr.adb (Compile): Put the compiling switches (in package
29915 Compiler and on the command line) immediately after "-c", instead of
29916 at the end of the command line invocation of the compiler, when
29917 compiling a non-Ada file.
29918 (Build_Global_Archive): When there is no need to rebuild the archive,
29919 set Global_Archive_Exists, so that the archive is passed to the linker
29922 2004-11-18 Robert Dewar <dewar@adacore.com>
29923 Sergey Rybin <rybin@adacore.com>
29926 Remove extra paren check from list of checks for redundant constructs
29927 Add documentation of new -gnatyx style check (check extra parens)
29928 Remove paragraph about gnatelim debug options.
29930 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29931 objects rather than forbidding dependencies on the package Ada.Streams.
29933 * sinfo.ads: Add ??? note that we should document pragmas passed to
29936 * g-expect.ads: Fix a few typos in the comments.
29938 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29940 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29943 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29945 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29947 2004-11-07 Andreas Schwab <schwab@suse.de>
29949 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29951 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29954 * Makefile.in (darwin): Set soext to .dylib.
29956 2004-10-26 Vincent Celier <celier@gnat.com>
29957 Thomas Quinot <quinot@act-europe.fr>
29959 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29960 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29961 there is no use of GNAT.Sockets.Constants.
29962 Remove remaining pragma Import for C_Write
29963 Remove C_Read and C_Write from internal implementation unit
29964 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29965 the read and write functions from the system runtime library is fine
29966 on UNIX but won't work under Windows).
29968 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29969 (Check_Selector): Use C_Recv instead of C_Read.
29970 Selectors are the GNAT.Sockets abstraction to perform a select()
29971 call on a set of descriptors. To allow abortion of an ongoing
29972 select operation, some data is written to a dedicated socket that
29973 is always monitored.
29974 Under Windows, the write and read library functions cannot operate
29975 on sockets, so we need to use send and recv instead, which is portable
29976 across all supported platforms.
29978 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29979 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29980 (using the read and write functions from the system runtime library is
29981 fine on UNIX but won't work under Windows).
29983 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29985 * mlib-tgt-darwin.adb: New file.
29987 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29988 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29989 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29990 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29993 * Makefile.in: Add support for building shared libraries under Darwin.
29994 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29995 the low level EH init subprogram to be called from __gnat_initialize.
29997 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29998 indicates which options to pass to the archive indexer.
30000 * mlib-utl.adb: Add support for calling ranlib with additional
30001 options. This is needed for instance under Mac OS X.
30002 (Ranlib_Options): New global variable, used to store the potential
30003 options to pass to ranlib.
30004 (Ar): Use Ranlib_Options when spawning ranlib.
30005 (Initialize): Set the value of ranlib option.
30007 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30009 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30010 instead of 8K, to reflect the real potential needs for stack-checking
30013 2004-10-26 Pascal Obry <obry@gnat.com>
30015 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30017 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30018 Windows only the initial thread stack size can be set so it is good to
30019 start we a low stack size.
30020 The OS will adjust the size as needed.
30022 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30023 Nicolas Setton <setton@act-europe.fr>
30025 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30026 "__unix__" instead of "unix".
30027 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30028 sections were just mistakenly ignored. The former is
30029 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30030 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30031 of hpux. This prevents an unwanted definition of the symbol
30032 convert_addresses in adaint.o.
30034 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30036 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30037 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30039 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30041 * a-filico.ads, a-filico.adb: fix incorrect header.
30043 2004-10-26 Javier Miranda <miranda@gnat.com>
30045 * a-ststio.ads: Fix typo in identifier
30047 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30049 * sem_ch4.adb: Minor reformatting.
30051 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30053 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30054 enabled, check the result of unary and binary operations when the
30055 expression is the right-hand side of an assignment.
30057 2004-10-26 Vincent Celier <celier@gnat.com>
30059 * clean.adb (Delete): Do not output warnings when in quiet output and
30060 not in verbose mode.
30061 (Force_Deletions): New Boolean flag, defaulted to False
30062 (Delete): Only delete a file if it is writable, and when
30063 Force_Deletions is True.
30064 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30065 (Usage): Line for new switch -f
30066 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30069 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30071 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30072 JM type only if its size matches that of the wrapper. When a size is
30073 prescribed and the field is not aliased, remove the wrapper of a JM
30074 type only if the size is not greater than that of the packed array.
30075 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30078 2004-10-26 Geert Bosch <bosch@gnat.com>
30080 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30081 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30082 (Pred): Implement in terms of Succ.
30084 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30086 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30087 unchecked conversion is safe for in-place use if the expression of the
30088 conversion is safe.
30089 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30090 be expandable in place even if the aggregate does not come from source.
30091 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30092 designated object of an allocator in place, rather than building it
30093 first on the stack. The previous scheme forces a full copy of the array,
30094 and may be altogether unsusable if the size of the array is too large
30095 for stack allocation.
30097 2004-10-26 Robert Dewar <dewar@gnat.com>
30099 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30100 compares if the component is atomic.
30102 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30103 array assignment if the component type is atomic.
30105 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30106 Eric Botcazou <ebotcazou@act-europe.fr>
30108 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30109 is aliased and is a by_reference type, do not pass by copy.
30110 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30111 detect whether the call is in the right side of an assignment or
30112 the expression of an object declaration. Recurse on component
30113 association within aggregates.
30114 Call it in the condition that determines whether the temporary is
30115 necessary for correct stack-checking.
30117 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30119 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30120 RACW_Type, used in the PolyORB version.
30121 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30122 version and the GARLIC version.
30124 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30125 Rename RCI_Info to RCI_Locator for better consistency between the
30126 GARLIC and PolyORB versions of the distributed systems annex.
30127 (DSA_Implementation_Name): This enumeration lists the possible
30128 implementations of the Partition Communication Subsystem for the
30129 Distributed Systems Annex (DSA). The three available implementations
30130 are the dummy stub implementation (No_DSA), and two versions based on
30131 two different distribution runtime libraries: GARLIC and PolyORB. Both
30132 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30134 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30137 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30138 between the GARLIC and PolyORB versions of the distributed systems
30140 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30142 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30144 * gnat1drv.adb: Suppress calling the back end when
30145 Frontend_Layout_On_Target is true.
30147 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30149 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30150 Set_Read_Only): New subprograms.
30151 These new routines allow the user to set or unset the Owner execute
30152 and Owner write permission flags on a file.
30154 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30155 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30157 2004-10-26 Matthew Gingell <gingell@gnat.com>
30159 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30161 2004-10-26 Pascal Obry <obry@gnat.com>
30163 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30164 memory before the faulting page we properly test the process read
30165 access for this address using appropriate Win32 routine.
30166 (HPUX sections): guard with "__hpux__" instead of "hpux".
30168 2004-10-26 Robert Dewar <dewar@gnat.com>
30170 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30171 entry parameter if pragma Unreferenced set, since we do not properly
30172 handle the case of multiple parameters.
30174 2004-10-26 Vincent Celier <celier@gnat.com>
30176 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30177 (Ada_Objects_Path.Add): For a library project, add to the object path
30178 the library directory only if there is no object directory or if the
30179 library directory contains ALI files.
30180 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30182 2004-10-26 Vincent Celier <celier@gnat.com>
30184 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30185 extension of library projects.
30187 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30188 path defaults to ".:<prefix>/lib/gnat".
30189 (Parse): For an extending all project, allow direct import of a project
30190 that is virtually extended.
30192 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30193 the specified name is directly imported, return its ID. Otherwise, if
30194 an extension of this project is imported, return the ID of the
30197 2004-10-26 Robert Dewar <dewar@gnat.com>
30199 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30200 (Sub3): New procedure, used by Scaled_Divide
30201 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30202 correct more than one instance of failure to propagate carries
30204 (Double_Divide): Handle overflow case of largest negative number
30205 divided by minus one.
30207 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30208 the case of a quotient value out of range.
30211 2004-10-26 Robert Dewar <dewar@gnat.com>
30213 * s-bitops.adb (Bit_Eq): Remove redundant check.
30215 * s-bitops.ads: Minor comment updates
30216 Change some occurrences of Address to System.Address
30218 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30220 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30222 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30223 accessibility check to prefix that is a protected operation.
30225 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30227 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30228 empty, post message on stub.
30230 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30231 Javier Miranda <miranda@gnat.com>
30233 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30234 current instance appears within a unit that is directly in the context
30236 Used to determine whether the body of the instance should be analyzed
30237 immediately after its spec, to make its subprogram bodies available
30238 for front-end inlining.
30239 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30240 constraint is not allowed on the component type (AARM 12.5.3(3))
30242 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30244 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30245 'Storage_Pool): enhance, document & limit detection of non-sharable
30248 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30250 * s-pooglo.ads: Add more documentation now that this pool is properly
30253 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30255 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30256 or protected type with discriminants, do not constrain the
30257 corresponding record type if the subtype declaration has no
30258 discriminant constraints. This can be the case in source code, or in
30259 the subtype declaration created to rename an actual type within an
30262 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30264 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30265 different kind of stub (possibly wrong name for file), do not check
30267 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30268 includes call to some function that returns an unconstrained type, do
30271 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30273 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30274 appear in the code for the main unit. Dependencies among units in the
30275 context of the main unit are established when those other units are
30276 compiled. Otherwise spurious elaboration constraints can generate
30277 incorrect elaboration circularities.
30279 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30280 Ed Schonberg <schonberg@gnat.com>
30282 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30283 subprogram is called with a parameter that is not an object name. This
30284 situation arises for some cases of illegal code, which is diagnosed
30285 later, and in this case it is wrong to call Is_Aliased, as that might
30286 cause a compiler crash.
30287 (Explain_Limited_Type): Refine previous fix to include
30288 inherited components of derived types, to provide complete information.
30290 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30291 is the prival for a protected object.
30292 It is necessary to mark this entity as a variable, in addition to
30293 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30294 modified to avoid checking the Aliased flag on entities that are not
30295 objects. (Checking that flag for non-objects is erroneous and could
30296 lead to a compiler crash).
30298 2004-10-26 Robert Dewar <dewar@gnat.com>
30300 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30301 X_Frac = 0.5, then we know that the number X must be positive.
30302 (Succ): Remove the same redundant test, and also fix the primary test
30303 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30305 (Decompose): Add fuller comments to spec
30307 2004-10-26 Pascal Obry <obry@gnat.com>
30309 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30310 validity (process must have read access). Set to 0 in all other cases.
30311 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30312 violation on Win32.
30313 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30314 segmentation violation.
30316 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30318 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30319 whose type is a constructed subtype of an aliased object with an
30320 unconstrained nominal subtype, convert the actual to the constructed
30321 subtype before taking its address.
30323 2004-10-26 Vincent Celier <celier@gnat.com>
30325 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30326 (Is_Path_Name_Case_Sensitive): New function
30328 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30329 (Base_Name, Simple_Name, Current_Directory, Compose,
30330 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30333 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30334 Vasiliy Fofanov <fofanov@act-europe.fr>
30335 Vincent Celier <celier@gnat.com>
30337 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30338 "memory management issues" section and document some of the useful
30339 memory pools provided as part of the GNAT library.
30340 Remove "virtual" from declaration of A::method2 in
30341 the simple example of Ada/C++ mixed system.
30342 Library Projects may be virtually extended: their virtual extensions
30343 are not Library Projects.
30344 Added section on extending project hierarchies.
30346 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30348 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30350 (__gnat_portable_spawn): Remove const.
30352 * mingw32.h (MAXPATHLEN): Check for previous definition.
30354 2004-10-17 Matthias Klose <doko@debian.org>
30356 * gnatvsn.ads: Set gnat library version to 4.0.
30358 2004-10-05 Vincent Celier <celier@gnat.com>
30360 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30362 2004-10-04 Laurent Guerby <laurent@guerby.net>
30365 * Makefile.in: Define and use RANLIB_FLAGS.
30367 2004-10-04 Pascal Obry <obry@gnat.com>
30369 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30370 other x86 platforms).
30372 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30374 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30375 in general and triggers stack alignment adjustment for thread entry
30376 points on targets where this is necessary.
30378 2004-10-04 Bernard Banner <banner@gnat.com>
30381 * Makefile.in: Add section for powerpc linux
30382 Add variant i-vxwork-x86.ads
30384 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30386 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30388 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30389 table registration calls when need be. Ensures no reference to the crt
30390 ctors symbol are issued in the SJLJ case, which avoids possible
30391 undefined symbol errors in the case of modules to be statically linked
30394 2004-10-04 Javier Miranda <miranda@gnat.com>
30396 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30397 in-line the code corresponding to subprogram Analyze_Actuals. In
30398 addition, analyze the actuals only in case of subprogram call.
30400 2004-10-04 Ed Falis <falis@gnat.com>
30402 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30404 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30406 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30407 in the documentation.
30409 2004-10-04 Robert Dewar <dewar@gnat.com>
30411 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30413 (Analyze_Block_Statement): Add circuitry to detect following dead code
30414 (Check_Unreachable_Code): Handle case of block exit
30416 2004-10-04 Robert Dewar <dewar@gnat.com>
30418 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30419 (XMatchD): Avoid warning for Logic_Error call
30421 2004-10-04 Robert Dewar <dewar@gnat.com>
30423 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30424 consider expressions buried within a procedure actual to be an actual.
30425 This caused some blowups with uses of packed slices within a procedure
30428 2004-10-04 Robert Dewar <dewar@gnat.com>
30430 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30431 longer need to be initialized to zero.
30432 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30433 initialized to zero.
30435 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30436 considered valid, even if the representation is modular. That's correct
30437 now that we no longer initialize packed modular arrays to zero.
30439 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30440 suffixes. These are now documented as the only cases in which the
30441 debugger ignores outer records.
30442 Previously, the spec allowed arbitrary suffixes for this purpose.
30443 Change name of LJM to JM for packed array pad records
30444 Create separate section on packed array handling, and add a whole new
30445 set of comments to this section describing the situation with packed
30446 modular types and justification requirements depending on endianness.
30448 2004-10-04 Robert Dewar <dewar@gnat.com>
30450 * a-except.adb: Add a comment for last change
30452 * einfo.ads: Minor spelling correction in comment
30454 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30456 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30459 * sem_util.ads: Minor comment update
30461 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30463 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30464 Inline_Always when in Configurable_Run_Time mode.
30466 * sem_prag.adb (Process_Convention): If entity is an inherited
30467 subprogram, apply convention to parent subprogram if in same scope.
30468 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30469 when in Configurable_Run_Time mode.
30471 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30473 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30474 class_wide type after component list has been inherited.
30476 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30478 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30479 Denotes_Previous_Actual, to handle properly the case of a private
30480 actual that is also the component type of a subsequent array actual.
30481 The visibility status of the first actual is not affected when the
30482 second is installed.
30483 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30484 make fully recursive the treatment of formals of packages declared
30486 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30487 the above on exit from an instantiation.
30488 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30489 current instantiation which is now complete.
30490 (Analyze_Package_Instantiation): No instantiated body is needed if the
30491 main unit is generic. Efficient, and avoid anomalies when a instance
30492 appears in a package accessed through rtsfind.
30494 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30496 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30497 do not generate a declaration for a temporary if the call is part of a
30498 library-level instantiation.
30500 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30502 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30503 searching for a limited component to flag.
30505 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30506 expansion of Input, to account for the fact that the implicit call
30507 generated by the attribute reference must freeze the user-defined
30508 stream subprogram. This is only relevant to 'Input, because it can
30509 appear in an object declaration, prior to the body of the subprogram.
30511 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30512 expansion can proceed and further errors uncovered.
30513 (Minor clean up): Fix cases of using | instead of \ for continuation
30516 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30518 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30520 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30521 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30522 Use gcc_assert and gcc_unreachable.
30524 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30525 specified alignment before validating size.
30526 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30527 stripped-down declaration for the type of the inner field when making
30530 * utils.c (finish_record_type): Do not compute the size in units
30531 incrementally. Instead compute it once for the rep clause case.
30532 Use gcc_assert and gcc_unreachable.
30534 2004-10-04 Vincent Celier <celier@gnat.com>
30536 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30538 (Is_Valid_Path_Name): Take '/' as a directory separator.
30540 2004-10-04 Vincent Celier <celier@gnat.com>
30542 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30543 (Extended_Project) only if Extended_Project is defined, to avoid
30545 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30547 (Parse_Single_Project): Ditto.
30549 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30550 Add_To_Project_Path for virtual projects.
30552 2004-10-04 Vincent Celier <celier@gnat.com>
30554 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30555 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30556 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30557 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30558 parameter Options_2.
30560 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30561 Build_Dynamic_Library with an empty Options_2.
30563 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30566 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30567 directory separator, if any.
30568 (Gprmake): Do not allow mains on the command line for library projects.
30569 Do not attempt to link when the project is a library project.
30570 (Library_Opts): New table to store Library_Options.
30571 (Build_Library): If Library_Options is specified, pass these options
30572 when building a shared library.
30574 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30576 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30577 the end of this procedure now that the unlock operation was inserted
30580 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30582 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30583 corresponding to the Preallocated_Stacks flags in System.
30584 (Get_Target_Parameters): Including the processing for
30585 Preallocated_Stacks.
30587 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30588 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30591 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
30592 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
30593 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30594 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30595 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30596 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30597 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30598 used to signal whether the compiler creates the required stacks and
30599 descriptors for the different tasks (when True) or it is done by the
30600 underlying operating system at run time (when False).
30601 It is initially set to False in all targets.
30603 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30604 if it is supported by the target.
30605 (Make_Task_Create_Call): Pass the stack address if it has been
30606 previously created. Otherwise pass a Null_Address.
30608 * snames.adb: Add _stack.
30610 * snames.ads: Add Name_uStack. Required to allow the expander to
30611 statically allocated task stacks.
30613 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30614 Stack_Address argument.
30615 Check that its value is equal to Null_Address because this target does
30616 not support the static stack allocation.
30618 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30620 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30623 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30625 * exp_dist.adb: Split declaration of asynchronous flag out of
30626 Add_RACW_Read_Attribute.
30627 Minor reformatting for better alignment with PolyORB version.
30628 Store the entity for the asynchronous flag of an RACW, rather than the
30629 expression, in the asynchronous flags table. This will allow this flag
30630 to be used in other subprograms beside Add_RACW_Read_Attribute.
30632 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30634 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30635 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30636 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30637 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30638 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30639 sockets constant MSG_NOSIGNAL (Linux-specific).
30640 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30641 all Send operations.
30642 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30643 from trigerring SIGPIPE.
30644 Rename components to avoid clash with Ada 2005 possible reserved
30646 (Check_Selector): When the select system call returns with an error
30647 condition, propagate Socket_Error to the caller.
30649 2004-10-01 Jan Hubicka <jh@suse.cz>
30651 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30653 2004-09-23 Robert Dewar <dewar@gnat.com>
30656 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30657 instead do this at freeze time (we won't do it if there is an address
30659 Change "pragma inline" to "pragma Inline" in information and error
30661 Minor reformatting.
30663 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30664 right way of doing things after all.
30665 (Freeze_Entity): For object, set Is_Public for imported entities
30666 unless there is an address clause present.
30668 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30670 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30671 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30672 ensures proper handling of types with rep clauses, which might have
30673 their TYPE_SIZE set already.
30675 2004-09-21 Robert Dewar <dewar@gnat.com>
30677 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30678 packed array types in both little- and big-endian cases. This change
30679 ensures that we no longer count on the unused bits being initialized
30680 for such types (and in particular ensures that equality testing will
30681 only read the relevant bits).
30682 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30683 These changes mean that we no longer need to initialize small packed
30685 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30686 optimization to an LJM field as to its parent field.
30688 * ada-tree.h, trans.c, utils.c, utils2.c:
30689 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30691 2004-09-20 Jan Hubicka <jh@suse.cz>
30693 * utils.c (gnat_finalize): Remove.
30694 (end_subprog_body): Directly call cgraph_finalize_function;
30695 do not lower the nested functions.
30697 2004-09-20 Robert Dewar <dewar@gnat.com>
30700 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30701 if an address clause is present, since that means that the Import
30704 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30706 * 5tsystem.ads: Removed, no longer used.
30708 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30709 Zack Weinberg <zack@codesourcery.com>
30711 * ada-tree.def: Use tree_code_class enumeration constants
30712 instead of code letters.
30713 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30714 Update for new tree-class enumeration constants.
30716 2004-09-17 Vincent Celier <celier@gnat.com>
30718 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30719 capabilities of the general project manager.
30721 2004-09-09 Vincent Celier <celier@gnat.com>
30723 * a-direct.ads: Add pragma Ada_05
30724 (Directory_Entry_Type): Give default value to component Kind to avoid
30725 not initialized warnings.
30727 * a-direct.adb (Current_Directory): Remove directory separator at the
30729 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30730 an existing directory.
30731 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30732 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30733 Convert the result to File_Size.
30735 * prj.ads: (Project_Error): New exception
30737 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30738 Prj.Com, not from Osint.
30739 (Attrs, Package_Attributes): Tables moved to private part of spec
30740 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30742 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30743 Prj.Project_Error after call to Fail.
30744 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30745 Fail. Check that package name is not already in use.
30747 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30748 used by tools, not only by the project manager, and to indicate that
30749 exception Prj.Prj_Error may be raised in case of problem.
30750 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30752 (Attrs, Package_Attributes): Table instantiations moved from the body to
30753 the private part to be accessible from Prj.Attr.PM body.
30755 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30756 from new package Prj.Attr.PM.

30813 raise Program_Error if called from a protected operation.
30815 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30816 the protected action nesting level.
30817 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30818 protected action nesting level.
30819 (Unlock): When pragma Detect_Blocking is active decrease the protected
30820 action nesting level.
30822 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30823 Protected_Action_Nesting.
30825 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30826 Common_ATCB record. It contains the dynamic level of protected action
30827 nesting for each task. It is needed for checking whether potentially
30828 blocking operations are called from protected operations.
30829 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30830 Detect_Blocking is active or not in the partition.
30832 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30864 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30865 insertion of the statement raising Program_Error. The run time
30866 contains the required machinery for handling that.
30868 * sem_util.ads: Change comment associated to procedure
30869 Check_Potentially_Blocking_Operation.
30870 This procedure does not insert a call for raising the exception because
30871 that is currently done by the run time.
30873 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30875 * init.c: Add the global variable __gl_detect_blocking that indicates
30876 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30877 making the pragma available at run time.
30878 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30881 pragma Detect_Blocking is active.
30883 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30885 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30886 DB is found in the ali file. Any unit compiled with pragma
30887 Detect_Blocking active forces its effect in the whole partition.
30889 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30890 Detect_Blocking is active and delay is called from a protected
30893 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30894 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30895 Detect_Blocking is active (0 otherwise).
30896 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30897 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30902 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30903 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30906 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30907 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30908 Update API in placeholder implemetation of s-parint to reflect changes
30909 in distribution runtime library.
30911 * sem_ch3.adb (Expand_Derived_Record): Rename to
30912 Expand_Record_Extension.
30914 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30915 primitive operations of potentially distributed object types that have
30916 non-controlling anonymous access formals.
30918 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30920 New implementation of expansion for remote access-to-subprogram types,
30921 based on the RACW infrastructure.
30922 This version of sem_dist is compatible with PolyORB/DSA as well as
30925 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30926 Asynchrronous that applies to a remote access-to-subprogram type, mark
30927 the underlying RACW type as asynchronous.
30929 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30930 __gnat_using_gnu_linker to 1.
30932 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30933 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to

30940 Expand_Record_Extension.
30941 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30942 a component declaration must remain attached at that point in the
30943 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30944 It is therefore necessary to take a copy of the expression when building
30945 the corresponding assignment statement in the init proc.
30946 As a side effect, in the case of a derived record type, we now see the
30947 original expression, without any rewriting that could have occurred
30948 during expansion of the ancestor type's init proc, and we do not need
30949 to go back to Original_Node.
30951 * exp_ch3.ads (Expand_Derived_Record): Rename to
30952 Expand_Record_Extension.

30959 subprogram. The proxy object is used as the designated object
30960 for RAS values on the same partition (unless All_Calls_Remote applies).
30961 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30962 System.Partition_Interface.Get_Unique_Remote_Pointer.

30967 New implementation of expansion for remote access-to-subprogram types,
30968 based on the RACW infrastructure.
30970 * exp_dist.ads (Copy_Specification): Update comment to note that this
30971 function can copy the specification from either a subprogram
30972 specification or an access-to-subprogram type definition.
30974 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30976 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30977 in an instance, between an explicit subprogram an one inherited from a
30978 type derived from an actual.
30980 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30981 add a polling call if the subprogram is to be inlined by the back-end,
30982 to avoid repeated calls with multiple inlinings.
30984 * checks.adb (Apply_Alignment_Check): If the expression in the address
30985 clause is a call whose name is not a static entity (e.g. a dispatching
30986 call), treat as dynamic.

30990 * g-trasym.ads: Minor reformatting
30992 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31001 2004-09-09 Pascal Obry <obry@gnat.com>
31003 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31004 enable map file generation. Add the right option to generate the map
31005 file if Map_File is set to True.
31007 * gnatdll.adb (Gen_Map_File): New variable.
31008 (Syntax): Add info about new -m (Map_File) option.

31036 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31037 of variable length temporaries for function return now that the
31038 back-end and gigi support it.

31089 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
31090 packed indexed component where array is an IN OUT formal. This
31091 generated garbage code previously.

31110 expander is not active (but check for unset reference to prefix of
31113 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31114 pragma Debug as an if statement with a constant condition, for
31115 consistent treatment of entity references contained within the
31116 enclosed procedure call.
31118 2004-09-01 Vincent Celier <celier@gnat.com>
31120 * bindgen.adb: (Set_EA_Last): New procedure
31121 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

31145 2004-09-01 Pascal Obry <obry@gnat.com>
31147 * gprcmd.adb (Extend): Do not output trailing directory separator. This
31148 is not needed and it confuses Windows GNU/make which does not report
31149 directory terminated by a slash as a directory.
31150 (gprcmd): Idem for "pwd" internal command.
31152 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31153 target names rewrite to fix regressions with recent version of

31205 2004-08-16 Pascal Obry <obry@gnat.com>
31207 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31208 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31209 option and not mdll anymore. Update comment.
31211 2004-08-16 Pascal Obry <obry@gnat.com>
31213 * bld.adb (Put_Include_Project): Properly handle directory separators
31216 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31229 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31231 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31232 for a global aliased object with a variable size and an unconstrained
31233 nominal subtype, pretend there is no initializer if the one we have is
31234 incomplete, and avoid referencing an inexistant component in there. The
31235 part we have will be rebuilt anyway and the reference may confuse
31236 further operations.
31238 2004-08-13 Thomas Quinot <quinot@act-europe.fr>
31240 * einfo.ads: Minor reformatting
31242 * lib-writ.adb (Output_Main_Program_Line): Do not set parameter

33218 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33219 includes case of a variable referenced on the left hand side of an
33220 assignment, therefore remove redundant code. Variables and prefixes of

33222 hand side. Warnings are now properly emitted when variables or prefixes
33223 are assigned but not read.

33230 "variable ... is assigned but never read" since other entities may read
33231 the memory location.

33887 Merge from tree-ssa-20020619-branch.
33889 * config-lang.in (boot_language, build_by_default): Set

33926 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to

33928 constructs. The call was a no-op because Unit_Node has already been
33929 Analyzed, and the tree fragments for the distribution stubs are
33930 analyzed as they are inserted in Exp_Dist.
33931 Update comment regarding to distribution stubs to reflect that we
33932 do not generate stub in separate files anymore.

33950 has been rewritten as an explicit dereference, retrieve type of
33951 original node to check for possibly unconstrained record type.
33953 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33955 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33956 overriding, use the operation of the parent unconditionally.
33958 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33959 operation when either operand is a literal, to avoid further
33962 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33963 overridden by a previous explicit declaration, mark the previous entity
33966 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33967 Is_Visibly_Controlled, to determine whether a declaration of a
33968 primitive control operation for a derived type overrides an inherited
33969 one. Add warning if the explicit declaration does not override.
33971 2004-05-10 Vincent Celier <celier@gnat.com>
33973 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33974 some cases when the sources are no longer present.
33976 * make.adb (Collect_Arguments): Fail if an external source, not part
33977 of any project need to be compiled, when switch -x has not been
33980 * makeusg.adb: Document new switch -x
33982 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33983 defaulted to False.

33987 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33988 gnatmake switch -x.
33990 * gnat_ugn.texi: Document new gnatmake switch -x
33992 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
33994 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
33996 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
33997 (process_attributes): Likewise.
33999 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34001 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34003 2004-05-10 Robert Dewar <dewar@gnat.com>
34005 * gnat_ugn.texi: Document that for config pragma files, the maximum
34006 line length is always 32767.
34008 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34009 literals is now allowed.
34011 * gnat-style.texi: Remove statement about splitting long lines before
34012 an operator rather than after, since we do not follow this rule at all.
34013 Clarify rule (really lack of rule) for spaces around exponentiation
34015 * sem_elim.adb: Allow concatenation of string literals as well as a
34016 single string literal for pragma arguments.
34018 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34020 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34021 written for append case.
34023 * frontend.adb: Changes to avoid checking max line length in config
34026 * g-os_lib.ads: Minor reformatting
34028 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34029 wrong in any case. Instead use standard value. Noticed during code
34032 * opt.ads (Max_Line_Length): New field, used to implement removal of
34033 limitation on length of lines when scanning config pragma files.
34035 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34036 makeutl.ads, makeutl.adb: Minor reformatting
34038 * scn.adb: Do not check line length while scanning config pragma files

35227 as is done for non-private derived record types.
35229 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35230 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35231 candidate interpretation in an overloaded call.

35245 complete assignment subtree which is now unnecessary, as the expansion
35246 of inlined call has been improved to preserve a consistent assignment
35247 tree. Note_Possible_Modification must be called only
35248 after checks have been applied, or else unnecessary checks will
35251 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35252 of explicit dereferences that do not Come_From_Source:

35254 pointer (an assignment to an implicit dereference must not be
35255 recorded as modifying the pointer);
35256 - do not rely on Original_Node being present (Analyze_Assignment
35257 calls Note_Possible_Modification on a copied tree).
35259 * sem_warn.adb (Check_References): When an unset reference to a pointer
35260 that is never assigned is encountered, prefer '<pointer> may be null'
35261 warning over '<pointer> is never assigned a value'.

35524 information for protected (wrapper) operation as well, to simplify gdb
35527 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35570 a classwide type (for which Is_Object_Reference holds), but it can
35571 also be a value conversion for an access-to-classwide type. In the
35572 latter case, there is an implicit dereference, and the original node
35573 for the prefix does not verify Is_Object_Reference.

35659 gigi has enough information to construct the record, and there is no
35660 place in the tree for the declaration.
35662 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35663 serial number for the dummy body that is built for analysis, to avoid
35664 inconsistencies in the generation of internal names when compiling
35667 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35669 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35672 2004-03-22 GNAT Script <nobody@gnat.com>
35674 * Make-lang.in: Makefile automatically updated
35676 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35678 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35679 * trans.c (tree_transform, emit_index_check): Likewise.
35680 * utils.c (build_template): Likewise.
35681 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35682 (maybe_unconstrained_array, unchecked_convert): Likewise.
35683 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.

35701 Minor reformatting.
35703 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35705 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35706 as regular exception objects and not as mere integers representing the
35707 condition code. The latter approach required some dynamics to mask off
35708 severity bits, which did not fit well into the GCC table based model.
35709 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35710 exception data objects. We don't it and it would conflict with the other
35711 external symbol we have to generate for such exceptions.
35713 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35714 the special code for VMS exceptions, since these are now represented
35715 as regular exceptions objects.
35717 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35719 * decl.c (debug_no_type_hash): Remove.

35721 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35723 2004-03-19 Laurent Guerby <laurent@guerby.net>
35725 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35726 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35728 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35730 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35731 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35732 (TYPE_RM_SIZE_INT): Directly use type.values.

35734 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35735 TYPE_VALUES, not TYPE_FIELDS.

35748 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35750 * adaint.c: Update comments.
35752 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35753 GNATLIB_SHARED for FreeBSD.
35755 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35757 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35758 When needed (stack checking) the stack size is retrieved
35759 from the VxWorks kernel.
35761 * Makefile.in: Flag -nostdinc is required when building the run time
35762 for avoiding looking for files in the base compiler.
35763 Add the VxWorks specific version of the package body for
35764 System.Stack_checking.Operations (5zstchop.adb).
35766 * Make-lang.in: Add the object file for
35767 System.Stack_Checking.Operations.

35775 checking from this package to package System.Stack_Checking.Operations.
35776 This way, stack checking operations are only linked in the final
35777 executable when using the -fstack-check flag.
35779 2004-03-18 Doug Rupp <rupp@gnat.com>
35781 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35791 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35792 the procedures Add_To_Path_File.
35793 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35794 making sure that each directory is present only once and, for object
35795 dirs, when a directory already present is added, the duplicate is
35796 removed and the directory is always put as the last in the table.
35797 Write the path files at the end of these accumulations.
35799 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35800 Files_Htable for all sources.
35802 * prj-proc.adb (Process): Remove restrictions between not directly
35803 related extending projects.

35811 parameter Trusted_Mode.
35813 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35815 * scn.adb (Determine_License): Take into account a degenerated case
35816 when the source contains only comments.
35818 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35820 * sem_warn.adb (Check_References): For a warning on a selected
35821 component that does not come from source, locate an uninitialized
35822 component of the record type to produce a more precise error message.
35824 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35826 * 3zsoccon.ads: Fix multicast options.
35828 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35831 2004-03-15 Robert Dewar <dewar@gnat.com>
35833 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35834 pragma used for a private type.
35836 * lib-xref.adb (Generate_Reference): Do not generate warning if
35837 reference is in a different unit from the pragma Unreferenced.
35839 * 5vtpopde.adb: Minor reformatting
35840 Fix casing of To_Task_ID
35842 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35843 flag if we have an unchecked conversion to an access type in the same
35846 2004-03-15 Geert Bosch <bosch@gnat.com>
35848 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35849 imaginary parts, use Double precision throughout.
35851 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35852 we want to be able to compile run-time with -gnata for testing, but
35853 this may also be instantiated in user code that is compiled with -gnata.
35855 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35857 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35858 codes. Having a separate type for this is useful to enforce consistency
35859 throughout the various run-time units.
35860 (Exception_Data): Use Exception_Code for Import_Code.
35862 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35870 component, now reflected by an exported accessor.
35871 (is_handled_by): New routine to compute whether the propagated
35872 occurrence matches some handler choice specification. Extracted out of
35873 get_action_description_for, and expanded to take care of the VMS
35875 (get_action_description_for): Use is_handled_by instead of an explicit
35876 complex condition to decide if the current choice at hand catches the
35877 propagated occurrence.
35879 * raise.h (Exception_Code): New type for C.
35881 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35882 System.Standard_Library.Exception_Code, to allow references from the
35883 pragma import/export expander.
35885 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35886 New accessors to allow easy access to GNAT exception data
35888 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35889 redundant Handled_By_Others component, helper for the personality
35890 routine which will now be able to call the appropriate exception data
35893 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35894 component of Standard_Exception_Type to be the closest possible to
35895 Exception_Code in System.Standard_Library, that we cannot get at this
35896 point. Expand a ??? comment to notify that this type node should
35897 probably be rewritten later on.
35899 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35900 registration call to include a pointer to the exception object in the
35903 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35904 instead of int and explicit bitmasks.
35906 2004-03-15 Vincent Celier <celier@gnat.com>
35908 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35909 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35911 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35912 longer needed now that it is in the spec of
35913 System.Tasking.Task_Attributes.
35915 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35917 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35919 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35921 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35922 taken care of in Scan_Make_Arg.
35923 (Scan_Make_Arg): Add the executable suffix only if the argument
35924 following -o, in canonical case, does not end with the executable
35925 suffix. When in verbose mode and executable file name does not end
35926 with executable suffix, output the executable name, in canonical case.
35928 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35929 to avoid warnings when instantiating Ada.Task_Attributes.
35932 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35933 in the correct order.
35935 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35943 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35945 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35946 tagged type is inherited, and the parent operation is not frozen yet,
35947 force generation of a freeze node for the inherited operation, so the
35948 corresponding dispatch entry is properly initialized.
35949 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35950 when looking for user-defined equality operation.
35952 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35953 boolean when locating primitive equality of tagged component.
35955 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35957 a temporary before expanding assignment into a loop.
35959 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35960 priority in full, to ensure that any expanded subepxressions of it are
35961 elaborated in the scope of the init_proc.

35964 after object declaration, skipping over code that may have been
35965 generated for validity checks.
35967 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35968 discriminants, ignore the known discriminants of its full view, if
35969 any, to check legality.
35971 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35972 component if type has unknown discriminants.
35973 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35974 null if type has unknown discriminants.
35976 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35977 for end label when present.
35979 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35980 temporary file, rather than an empty string.
35982 2004-03-15 Ed Falis <falis@gnat.com>
35984 * s-thread.adb: Removed, no longer used.
35986 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36006 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36007 Insert_Dereference_Action when rewriting an implicit dereference into
36008 an explicit one, this will be taken care of during expansion of the
36009 explicit dereference.
36010 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36011 of non-packed slices, since the dereference action generated by
36012 expansion of the explicit dereference is needed in any case.
36013 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36014 analyze and resolve the rewritten explicit dereference so it is seen
36016 (Insert_Dereference_Action): This procedure is now called only for the
36017 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36018 dereferences that do not come from source (including explicit
36019 dereferences resulting from rewriting implicit ones), but do not
36020 recursively insert a check for the dereference nodes contained within
36022 (Insert_Dereference_Action): Clarify and correct comment.

36899 checks for bitfield creation are triggered.
36900 (finish_record_type): During last pass over the fields, clear

37288 be modified by the binder generated main program if the -D switch is
37291 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37292 imported functions (since now we expect this to be done for imported
37295 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37296 Minor reformatting throughout
37298 * 5zinit.adb: Minor reformatting

37302 doing reformatting)
37304 * sprint.adb: Minor updates to avoid -gnatwa warnings
37306 * s-secsta.ads, s-secsta.adb:
37307 (SS_Get_Max): New function to obtain high water mark for ss stack
37308 Default_Secondary_Stack is not a constant since it may be modified by
37309 the binder generated main program if the -D switch is used.
37311 * switch-b.adb: New -Dnnn switch for binder
37314 Make -gnatg imply all warnings currently in -gnatwa

37345 Acquire new SS indication of secondary stack use from ali files
37347 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37348 (since now we expect this to be done for imported functions)
37350 * bindgen.adb: Generate call to modify default secondary stack size if
37353 * bindusg.adb: Add line for new -D switch
37355 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37356 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37357 Add circuitry for both records and arrays to avoid gigi
37358 processing if the type involved has non-bit-aligned components
37360 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37361 N_String_Literal node always references an E_String_Literal_Subtype
37362 entity. This may not be true in the future.
37363 (Possible_Bit_Aligned_Component): Move processing of
37364 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37366 * exp_ch6.adb (Expand_Thread_Body): Pick up
37367 Default_Secondary_Stack_Size as variable so that we get value modified
37368 by possible -Dnnn binder parameter.
37370 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37371 (Type_May_Have_Bit_Aligned_Components): New function.
37373 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37383 unless explicit Pure_Function pragma given, to avoid insidious bug of
37384 call to non-pure imported function getting eliminated.

37406 * rtsfind.adb (Load_Fail): Give full error message in configurable
37407 run-time mode if all_errors mode is set. This was not done in the case
37408 of a file not found, which was an oversight.
37409 Note if secondary stack unit is used by compiler.
37411 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37412 ineffective elaborate all pragmas on non-visible packages (this
37413 happened when a renamed subprogram was called). Now the elaborate all
37414 always goes on the package containing the renaming rather than the one
37415 containing the renamed subprogram.
37417 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37418 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37420 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37421 has an Etype that references an E_String_Literal.
37422 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37423 always references an E_String_Literal_Subtype entity. This may not
37424 be true in the future.
37426 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37429 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37432 2004-01-05 Ed Falis <falis@gnat.com>

37439 * bld.adb: Minor comment updates
37440 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37443 * make.adb (Gnatmake): Special process for files to compile/check when
37444 -B is specified. Fail when there are only foreign mains in attribute
37445 Main of the project file and -B is not specified. Do not skip bind/link
37446 steps when -B is specified.
37448 * makeusg.adb: Document new switch -B

37471 -gnatwa warning on static condition.
37473 2004-01-05 Doug Rupp <rupp@gnat.com>

37477 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37479 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37480 all attributes, including read-only attribute.
37482 2004-01-05 Pascal Obry <obry@gnat.com>

37485 library naming scheme.
37487 * mlib-prj.adb (Build_Library): Generate different names for the static
37488 or dynamic version of the GNAT runtime. This is needed to support the
37489 new shared library naming scheme.

37491 based on the new naming scheme.
37493 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37494 scheme for the shared runtime libraries.
37497 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37499 (install-gnatlib): Do not create symlinks for shared libraries.
37500 (gnatlib-shared-default): Idem.
37501 (gnatlib-shared-dual-win32): New target. Not used for now as the
37502 auto-import feature does not support arrays/records.
37503 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37504 (gnatlib-shared-vms): Fix shared runtime libraries names.
37506 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37507 dependent runtime shared library name.
37509 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37511 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37514 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37516 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37517 protected objects when allocator has a subtype indication, not a
37518 qualified expression. Note that qualified expressions may have to be
37519 checked when limited aggregates are implemented.
37521 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37522 pure, emit warning.
37523 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37524 subprogram is imported, remove warning.
37526 2004-01-05 Geert Bosch <bosch@gnat.com>
37528 * s-poosiz.adb: Update copyright notice.
37529 (Allocate): Use Task_Lock to protect against concurrent access.
37530 (Deallocate): Likewise.

37568 * cstand.adb (Create_Standard): Change the way how the declaration of
37569 the Duration type is created (making it the same way as it is for all
37570 the other standard types).
37572 2003-12-17 Robert Dewar <dewar@gnat.com>
37574 * s-crtl.ads: Fix header format
37575 Change Pure to Preelaborate

37580 the expression type only if it is declared in the current unit.
37582 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37583 are universal and already analyzed, as can occur in constrained
37584 subcomponents that depend on discriminants, when one constraint is a
37587 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37588 type Any_Fixed is legal as the argument of a conversion, if only one
37589 fixed-point type is in context.

37602 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37603 (Gnatchop): Do not set failure status when reporting the number of
37606 2003-12-15 Doug Rupp <rupp@gnat.com>
37608 * s-ctrl.ads: New file.

37628 * Make-lang.in: Makefile automatically updated
37630 2003-12-11 Ed Falis <falis@gnat.com>
37632 * 5zinit.adb: Clean up.
37634 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37635 to __gnat_map_signal, imported from init.c to support

37669 Minor reformatting throughout
37671 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37673 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37674 bounds of a loop, create a separate block in order to generate proper
37675 cleanup actions to prevent memory leaks.
37677 * sem_res.adb (Resolve_Call): After a call to
37678 Establish_Transient_Scope, the call may be rewritten and relocated, in
37679 which case no further processing is needed.
37681 * sem_util.adb: (Wrong_Type): Refine previous fix.
37682 Fixes ACATS regressions.
37685 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37688 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37690 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37691 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37694 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37697 2003-12-08 Robert Dewar <dewar@gnat.com>
37699 * 7sintman.adb: Minor reformatting
37701 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37702 standard linker options to get standard libraries linked. We now plan
37703 to provide dummy versions of these libraries to match the appropriate
37704 configurable run-time (e.g. if a library is not needed at all, provide
37705 a dummy empty library).
37707 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37708 options (-L parameters and standard libraries). What we plan to do is
37709 to provide dummy libraries where the libraries are not required.
37711 * gnatbind.adb: Minor comment improvement
37713 2003-12-08 Javier Miranda <miranda@gnat.com>
37715 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37716 aggregate in the parent. Otherwise constants with limited aggregates
37717 are not supported. Add new formal to pass the component type (Ctype).
37718 It is required to call the corresponding IP subprogram in case of
37719 default initialized components.
37720 (Gen_Assign): In case of default-initialized component, generate a
37721 call to the IP subprogram associated with the component.
37722 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37723 of aggregate with default initialized components.
37724 (Has_Default_Init_Comps): Improve implementation to recursively check
37725 all the present expressions.
37727 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37728 to indicate that the initialization call corresponds to a
37729 default-initialized component of an aggregate.
37730 In case of default initialized aggregate with tasks this parameter is
37731 used to generate a null string (this is just a workaround that must be
37732 improved later). In case of discriminants, this parameter is used to
37733 generate a selected component node that gives access to the discriminant
37736 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37737 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37738 allocated aggregates with default-initialized components.
37740 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37741 the box notation is used in positional aggregates.

37757 * prj-part.adb (With_Record): New component Node
37758 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37759 Set the scanner to return ends of line and comments as tokens, if
37760 Store_Comments is True.
37761 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37762 comments are associated with these nodes. Store the node IDs in the
37764 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37766 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37767 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37768 current project. Call Tree.Restore afterwards. Set the various nodes
37769 for comment storage (Next_End, End_Of_Line, Previous_Line,
37772 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37773 defaulted to False.
37775 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37776 to False. When Truncated is True, truncate the string, never go to the
37778 (Write_End_Of_Line_Comment): New procedure
37779 (Print): Process comments for nodes N_With_Clause,

39522 a subunit is missing.
39523 (Instantiate_Subprogram_Body): If body of function is missing, set type
39524 of return expression explicitly in dummy body, to prevent cascaded
39525 errors when a subunit is missing.
39529 (Access_Subprogram_Declaration): Verify that return type is valid.
39533 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39538 (Corresponding_Discriminant): If the scope of the discriminant is a
39539 private type without discriminant, use its full view.

41564 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41565 function approach did not work well because of a side effect (the
41566 function call could reallocate the table which was being indexed
41567 using its result). Fixes ada/4851.

41626 Add 2001 to copyright date
41628 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no

41845 When using a project file, fail if specified executable is relative
41846 path with directory information, and prepend executable, if not

41932 to Hbound, but no actual example of failure has been found.
41934 2001-12-17 Laurent Pautet <pautet@gnat.com>
41937 Fix comment of Shutdown_Socket and Close_Socket. These functions
41938 should not fail silently because if they are called twice, this
41939 probably means that there is a race condition in the user program.
41940 Anyway, this behaviour is consistent with the rest of this unit.
41941 When an error occurs, an exception is raised with the error message
41942 as exception message.

43276 instead of the previous simple checksum algorithm.
43277 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43278 (Set_Source_Table): idem.
43281 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43282 instead of simple checksum.
43283 (CRC_Match): new function.
43284 (CRC_Error): new constant.
43286 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43287 a CRC now and not a simple checksum. A CRC uses lower-case hex
43288 letters, fixes ambiguity in parsing.
43290 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43291 is what this variable will store.
43293 * bcheck.adb: Change reference to chechsum in comments by CRC.
43294 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43295 rename All_Checksum_Match to All_CRC_Match. Change due to API
43296 renaming since now GNAT does not use a simple checksum but a
43297 CRC using GNAT.CRC32.
43299 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43300 now and not anymore a simple checksum.

43337 Update comments for the CRC.
43339 * types.adb (Hex): Use lowercase for the letter part.
43341 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43342 for a word. This is currently used only for CRC. In previous version,
43343 the checksum was using a representation with all letter being
43344 upper-case. With the new implementation (using CRC) we do not remove
43345 the 32th bit of the CRC, so we can have an upper-case starting letter
43346 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43347 It is ambigous since the CRC was optional and could be followed by
43348 options like EB, EE. So now this routines uses lower-case letter for
43349 the hexadecimal representation. Strange enough only lower case letters
43350 where checked in Scan_ALI (even if this was not a possible case).
43352 * gnatvsn.ads (Library_Version): changed to 3.15a.
43354 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43357 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

43362 (Accumulate_Checksum): Modify to use System.CRC32.
43364 * ali-util.ads: Redo changes of previous revision to continue to use
43365 the word Checksum. Add 2001 to copyright notice.
