2016 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2017 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4112 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4113 convention from its base type, do not set the type to that of integer,
4114 because it may inherit a size clause.

4156 (P_Access_Definition): Change the error message when parsing "access
4157 all" in Ada 95 mode. The message no longer forces the user to recompile

4178 the visible part of the spec of a remote types unit.

4180 New local subprogram Is_Valid_Remote_Object_Type, replaces
4181 Is_Recursively_Limited_Private.
4182 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4183 non-controlling formals (and the return type, even though this is not
4184 explicit in the standard) must support external streaming.
4185 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4186 as above for of RAS types and RCI subprograms. (The return type is not

4192 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4193 Is_Remote_Call_Interface to identify RACW types in a stable and
4194 consistent way. We used to rely in this predicate on the privateness of
4195 the designated type and its ancestors, but depending on the currently
4196 visible private parts, this caused false negatives. We now uniformly
4197 rely on checks made at the point where the RACW type is declared.

4211 Add missing escaping of all-caps word 'CPP' in error messages.
4212 (Build_Discriminated_Subtype): Do not inherit representation clauses
4213 from parent type if subtype already carries them, because they are
4214 inherited earlier during derivation and already include those that may
4215 come from a partial view.
4217 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4218 Check the declarations of a subprogram body for proper deferred
4219 constant completion.

4252 (Add_One_Interp): Ignore any interpretation that is a primitive
4253 operation of an RACW stub type (these primitives are only executed
4254 through dispatching, never through static calls).
4255 (Collect_Interps): When only one interpretation has been found, set N's
4256 Entity and Etype to that interpretation, otherwise Entity and Etype may
4257 still refer to an interpretation that was ignored by Add_One_Interp,
4258 in which case would end up with being marked as not overloaded but with
4259 an Entity attribute not pointing to its (unique) correct interpretation.
4261 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4264 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4274 (Print_Itype): Do not modify the sloc of the component type of a
4275 (packed) array itype, because it is an unrelated type whose source
4276 location is independent of the point of creation of the itype itself.

4318 equivalent representation, but has the advantage of allowing
4319 compilation of this file under 64 bits platforms.

8519 WITH clause on a private sibling.
8520 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8521 child unit is a renaming, create an implicit with_clause on that

8626 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8627 Timed_Entry_Call): Analyze the triggering statement as the first step of
8628 the processing. If this is a dispatching select, postpone the analysis

8631 replicated some of the select statements. In case the Expander is
8632 disabled, perform regular analysis.
8633 (Check_Triggering_Statement): New routine.
8634 (Analyze_Requeue): Exclude any interpretations that are not entries when
8635 checking overloaded names in a requeue. Also test type conformance for

9249 additional management on these nodes in Expand_Interface_Actuals.
9251 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9252 that handles use of 'Access and 'Unchecked_Access applied to

9298 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info

9300 able to extract the stack boundaries for stack checking.

9345 association for an access component, add an association with null as
9346 the expression. Remove testing for array subtypes and the setting in
9347 that case of Ctyp to the array component type, which prevented proper
9348 inclusion of an association for null-initialized arrays. Collapse
9349 condition that tests for array subtypes into just a test of
9350 Is_Partially_Initialized_Type (which already covers arrays anyway).

9367 * sem_ch4.adb: Minor code and comment reformatting.
9368 (Analyze_Allocator): When the designated type of an unconstrained

9500 (gigi): Rename and change type of number_units parameter, change
9501 type of file_info_ptr parameter.
9502 * trans.c (number_files): New global variable.
9503 (gigi): Rename and change type of number_units parameter, change
9504 type of file_info_ptr parameter.
9505 If mapped location support is enabled, create the isomorphic mapping
9506 between source files and line maps.
9507 (Sloc_to_locus): If mapped location support is enabled, translate
9508 source location into mapped location.
9509 (annotate_with_node): Rename into set_expr_location_from_node.

9536 Add a section on leap seconds control along with two entities used to
9537 enable and disable leap seconds support. The array Leap_Second_Times is
9538 now constant and contains hard time values pre-generated. Remove
9539 all elaboration code used to populate the table of leap seconds.
9542 Add entity Leap_Seconds_Support to the list of global run-time variables
9543 along with a comment on its usage and values.

9559 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9561 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9563 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9564 function which can be called by the debugger to interrupt the tasks of
9565 an Ada application asynchronously, as needed on VxWorks.

9599 2007-09-26 Javier Miranda <miranda@adacore.com>
9600 Eric Botcazou <ebotcazou@adacore.com>
9603 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9604 indirection added to the HT_Link component of the TSD. This is required
9605 to statically allocate the TSD.
9608 Minor reordering of the declarations in the private part. Required to
9609 add a level of indirection to the contents of the TSD component HT_Link.
9610 This is required to statically allocate the TSD.
9612 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9613 Is_Statically_Allocated set from constant objects.
9614 Do not make exported constants created by the compiler volatile.
9615 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9618 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9619 before returning them.
9621 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9622 public part of the package.
9623 (Make_DT): Move HT_Link component out of the TSD record. For this
9624 purpose Make_DT now declares a separate object that stores the
9625 HT_Link value, and initializes the TSD component with the address
9626 of this new object. The addition of this level of indirection is
9627 required to statically allocate the TSD because the TSD cannot
9628 have variable components.
9629 (Expand_Interface_Conversion): Improve the expanded code.
9630 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9632 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9633 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9634 if we are building static dispatch tables then we must not generate
9635 extra code to register the primitive because the dispatch table will
9636 be built at the end of the library package; otherwise we notify that
9637 we cannot build the static dispatch table.
9639 2007-09-26 Robert Dewar <dewar@adacore.com>
9641 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9656 for thunks associated with interface types.
9658 * einfo.ads: Improve documentatation of Is_Internal
9659 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9660 associated with interface types.
9661 Extensive comment fixes regarding flags that appear in all entities. The
9662 documentation is now consistent for all such flags (there were a number
9663 of errors in the documentation in this regard).
9665 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9667 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9668 of these procedures are passed a function call that already has
9669 build-in-place actuals (testing new flag
9670 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9671 the case where processing continues.
9672 (Expand_Call): If the call is generated from a thunk body then we
9673 propagate the extra actuals associated with the accessibility
9674 level of the access type actuals.
9676 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9677 of each extra formal of a protected operation to reference the
9678 corresponding extra formal of the subprogram denoted by the
9679 operation's Protected_Body_Subprogram.
9681 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9682 N_Function_Call nodes.
9684 2007-09-26 Robert Dewar <dewar@adacore.com>
9686 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9688 * debug.adb: Add d.s flag.
9690 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9692 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9693 debug variable so that it won't be initialized when pragma
9694 Initialize_Scalars is in effect.
9696 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9698 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9699 initialization of a full view. This is moved to
9700 Analyze_Package_Specification.
9702 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9703 preelaborable initialization of a full view in entity loop.
9704 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9705 its child units are use-visible only if they are visible child units.
9707 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9708 whether an expression can be used within a type declaration that
9709 requires preelaborable init.
9710 (Check_Components): Replace inline code that does partial checking for
9711 preelaborable default expressions with call to
9712 Is_Preelaborable_Expression.
9713 (Has_Preelaborable_Initialization): In the case of a generic actual
9714 subtype, (that is, Is_Generic_Actual is True), return the result of
9715 applying Has_Preelaborable_Initialization to the generic actual's base
9718 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9720 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9721 call to Jan_1_Day _Of_Week to optimize its performance.
9722 (Is_Leap): Move the routine to the scope of Week_In_Year.
9723 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9724 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9725 avoids calling Time_Of and Split, thus making it more efficent.
9726 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9728 * g-calend.ads (Week_In_Year): Change comment to reflect new
9731 2007-09-26 Emmanuel Briot <briot@adacore.com>
9733 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9734 Command_Line): New types
9735 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9736 support for defining how switches can be grouped on a command line (as
9737 is the case for -gnatw... for GNAT), and how simple switches can be
9738 used as aliases for more complex switches (-gnatwa is same as
9740 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9741 (Start, Current_*): New subprograms
9742 Added support for parsing an array of strings in addition to the real
9744 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9745 be moved from the body to the private part of the spec.
9746 (*): All subprograms now have an extra parameter with default value to
9747 specify which parser should be used. For backward compatibility, it
9748 defaults to parsing the command line of the application. They were also
9749 modified to properly handle cases where each of the argument does not
9750 start at index 1 (which is always true for Ada.Command_Line, but not
9751 when processing any Argument_List).
9752 (Free): New subprogram
9753 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9754 Argument): New subprograms
9755 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9756 special characters like ':', '=',... are now handled in a single place,
9757 which makes the code more extensible eventually.
9758 (Getopt, Full_Switch): When the switch was returned as part of the
9759 special character '*', make sure it is prepended by the switch character
9760 ('-' in general), so that the application knows whether "foo" or "-foo"
9761 was specified on the command line.
9763 2007-09-26 Florian Villoing <villoing@adacore.com>
9765 * g-dirope.adb (Remove_Dir): In case we are removing directories
9766 recursively, make sure that if an exception is raised during the
9767 processing, the current working directory is reset to its initial
9768 value before propagating the exception.
9770 2007-09-26 Vincent Celier <celier@adacore.com>
9772 * gnatbind.adb: If there are several ALI files specified and there is
9773 a main program to bind, the first ALI is expected to contain the main
9774 subprogram and the names of the binder generated files will be derived
9775 from the first ALI file name.
9776 (Gnatbind): Fix insertion character in invocation of Error_Msg
9778 2007-09-26 Vincent Celier <celier@adacore.com>
9780 * gnatcmd.adb (Check_Files): Do not include sources that have been
9781 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9783 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9785 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9786 information about each of its index types, following the type
9787 reference for its component type.
9789 2007-09-26 Vincent Celier <celier@adacore.com>
9791 * make.adb: (Kill): New procedure (__gnat_kill imported)

9793 were previously local to procedure Compile_Sources.
9794 (Sigint_Intercepted): Send signal SIGINT to all outstanding
9795 compilation processes.

9798 sources, so that the correct paths will be found.
9800 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9802 2007-09-26 Vincent Celier <celier@adacore.com>
9804 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9806 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9807 Replace components Compiler_Min_Options and Binder_Min_Options with
9808 Compiler_Required_Switches and Binder_Required_Switches in record
9810 Remove components Default_Language and Config in Project_Tree_Data,
9813 * prj-attr.adb: New attributes Required_Switches (<language>) in
9814 packages Compiler and Binder.
9816 * prj-nmsc.adb: Major rewrite of the processing of configuration
9817 attributes for gprbuild. No impact on GNAT tools.
9819 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

9825 (Process): Implementation now uses the two new procedures
9827 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9828 from the project config, not the tree config that no longer exists.
9830 2007-09-26 Vincent Celier <celier@adacore.com>

9851 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9853 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9854 ancestor of the derived type, the operations are inherited from the
9855 primary dispatch table of the parent.
9856 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9857 when the context is an explicit type conversion.
9859 2007-09-26 Ed Schonberg <schonberg@adacore.com>

9904 no sources, but is an extending project.
9906 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9908 * trans.c: Fix misplaced #define.
9910 2007-09-22 Eric Botcazou <ebotcazou@adacore.com>
9912 * utils2.c (build_unary_op) <ADDR_EXPR> [INDIRECT_REF]: Propagate

10159 potentially be called.
10160 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10161 body for 'Output when the type is abstract (only the creation of the
10162 body for 'Input is excluded when the type is abstract).

10164 statement, so that False will be returned for TTS_Stream_Input if the
10165 associated tagged type is an abstract extension. Add comments for
10167 (Expand_N_Object_Declaration): For the case of a shared passive
10168 variable, insert init proc call only after the shared variable
10169 procedures have been processed, because the IP call needs to undergo
10170 shared passive variable reference expansion, which requires these
10171 procedures to be available (and elaborated).

10183 type, retrieve its value from the aggregate itself, where it must have
10186 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10187 to remove other spurious ambiguities on arithmetic operations involving
10188 literals and addresses, on systems where Address is a visible integer
10189 type, when the operator is called in functional notation.
10190 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10191 is legal when the types match, even if the operation is currently
10194 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10196 * sem_ch12.adb (Build_Local_Package): A formal package with no
10197 associations is legal if all formals have defaults. It is not

10226 a debug renaming declaration specially.
10228 2007-09-08 Eric Botcazou <ebotcazou@adacore.com>
10230 * decl.c (gnat_to_gnu_entity) <Object>: Simplify the condition under
10231 which a constant renaming is treated as a normal object declaration.

10233 the N_Indexed_Component case.
10234 <N_Indexed_Component>: Fall through to above case.

10319 address type that is a visible integer type.
10321 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10322 exceptions never being raised.
10323 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10339 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10340 library-level package renaming, pass the declaration associated with
10341 the renaming's special debug variable to Qualify_Entity_Names to ensure
10342 that its encoded name is properly qualified.
10344 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10345 occurring in the list of entities to qualify, and do not attempt to
10346 traverse an entity list in that case. Variables associated with
10347 ` library-level package renamings can now occur in the table.

10371 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10372 concatenations of string literals into a single literal, in order to
10373 avoid very deep recursion in the front end, which was causing stack
10376 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10377 string, and the right operand is a string literal (the case of "" &
10378 "..."), optimize by avoiding copying the right operand -- just use the
10379 value of the right operand directly.
10381 * stringt.adb (Store_String_Chars): Optimize by growing the
10382 String_Chars table all at once, rather than appending characters one by
10384 (Write_String_Table_Entry): If the string to be printed is very long,
10385 just print the first few characters, followed by the length. Otherwise,
10386 doing "pn(n)" in the debugger can take an extremely long time.
10388 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10389 Store_String_Char with Store_String_Chars.

10403 clauses of subunits, ignore limited_with_clauses that are illegal and
10404 have not been fully analyzed.
10406 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10408 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10409 flag, for effiency. It is called when analyzing arithmetic operators
10410 and also for actuals in calls that are universal_integers. The flag is
10411 set for the predefined type address, and for any type or subtype
10414 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10415 Universal_Integer, when the formal is a descendent of address and the
10416 call appears in user code.

10483 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10484 associated with Standard_Debug_Renaming_Type, to be used as the type of

10486 renaming declarations.
10488 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10489 (Set_Debug_Renaming_Link): Change to set Node25.

10499 and the entity of the renaming declaration.
10500 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10501 part of the name of a variable that has a Debug_Renaming_Link.
10503 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

10509 Javier Miranda <miranda@adacore.com>
10511 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10512 ancestor part given by an aggregate to test for an unchecked conversion,
10513 since this can occur in some cases when the ancestor part is a function
10514 call, and we don't want to fall into the recursive call to this
10515 procedure in that case.
10517 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10518 stream attributes on limited types to account for user-specified
10519 attributes as well as whether Input (resp. Output) becomes available
10520 due to Read (resp. Write) being available for the type. Change Boolean
10521 variable to the more accurate name
10522 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10523 double-"not" predicate at beginning of return statement to more
10524 understandable form.
10526 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10527 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10528 in a block statement and use that as the first statement of the
10529 expanded return rather than incorrectly using the handled sequence as
10530 the first statement.
10532 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10533 operation, generate an explicit freeze node for it rather than
10534 generating extra formals, to ensure that gigi has the proper order of
10535 elaboration for anonymous subtypes in the signature of the subprograms.
10536 (Build_In_Place_Formal): Move assertion to beginning of loop.
10537 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10540 applied to a function call (occurs for some cases of 'Input).
10542 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10543 2005, generate an extended return statement enclosing the result object
10546 * freeze.adb (Freeze_Record_Type): Extend the current management of
10547 components that are access type with an allocator as default value: add
10548 missing support to the use of qualified expressions of the
10549 allocator (which also cause freezing of the designated type!)
10550 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10551 dispatching operation, since extra formals may be needed by calls to
10552 build-in-place functions (such as stream 'Input).
10554 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10555 formals for 'Constrained and accessibility level in the case of a
10556 predefined dispatching operation.
10558 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10559 point, no need to find the parent node.
10561 2007-08-16 Javier Miranda <miranda@adacore.com>
10563 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10564 and entry barriers.
10566 2007-08-16 Javier Miranda <miranda@adacore.com>
10568 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10569 is not really required and can introduce regression with the debugger.
10570 The original problem is fixed with the patch written for checks.adb.
10572 2007-08-16 Thomas Quinot <quinot@adacore.com>
10574 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10584 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10585 parameter Including_Non_Switch, defaulted to True. When
10586 Including_Non_Switch is False, options that are not switches and
10587 appear as relative path are not converted to absolute paths.
10589 2007-08-16 Nicolas Roche <roche@adacore.com>
10591 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10602 from the immediate ancestor of Main_Unit_Entity.
10603 (Install_Limited_Withed_Unit): Do not install the limited view of
10604 package P if P is reachable through an ancestor chain from package C
10605 and C also has a with clause for P in its body.

10607 (Has_With_Clause): New routine.
10609 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10611 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10612 generic for an enclosing instance is a global reference, even though
10613 its scope is the enclosing instance.
10615 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10616 Javier Miranda <miranda@adacore.com>
10618 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to

10626 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10629 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10631 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10632 implements an operation inherited from a progenitor interface, verify
10633 that they are subtype-conformant.

10636 Bob Duff <duff@adacore.com>
10637 Nicolas Setton <setton@adacore.com>
10639 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10640 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10641 the statement which is being resolved comes from a predefined library
10642 unit, all non-predefined library interpretations are skipped.
10643 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10644 but the "&" is user defined, give an error, because the folding would

10648 the parser has folded a long sequence of concatenations of string
10651 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10652 and "JMP_BUF" variables as artificial.
10653 (N_String_Literal): Do not use alloca for very long string literals. Use

10701 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10702 Suppress unmodified in-out parameter warning in some cases
10703 This patch is a also fairly significant change to the way suppressible
10704 checks are handled.
10706 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10707 needed for access to concurrent record types generated by the expander.
10708 (Generate_Range_Check): When generating a temporary to capture the
10709 value of a conversion that requires a range check, set the type of the
10710 temporary before rewriting the node, so that the type is always
10711 properly placed for back-end use.
10712 (Apply_Float_Conversion_Check): Handle case where the conversion is
10714 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10731 parameters when deciding whether to apply a run-time accessibility
10733 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10734 aggregate code before allocator, and ahead of declaration for
10735 temporary, to prevent access before elaboration when the allocator is
10736 an actual for an access parameter.
10737 (Expand_N_Type_Conversion): On an access type conversion involving an
10738 access parameter, do not apply an accessibility check when the
10739 operand's original node was an attribute other than 'Access. We now
10740 create access conversions for the expansion of 'Unchecked_Access and
10741 'Unrestricted_Access in certain cases and clearly accessibility should
10742 not be checked for those.
10744 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10745 includes a type conversion of a packed component that has been expanded,
10746 recover the original expression for the object, and use this expression
10747 in the post-call assignment statement, so that the assignment is made
10748 to the object and not to a back-end temporary.
10749 (Freeze_Subprogram): In case of primitives of tagged types not defined
10750 at the library level force generation of code to register the primitive
10751 in the dispatch table. In addition some code reorganization has been
10752 done to leave the implementation clear.
10753 (Expand_Call): When expanding an inherited implicit conversion,
10754 preserve the type of the inherited function after the intrinsic
10755 operation has been expanded.
10757 * exp_ch2.ads, exp_ch2.adb
10758 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10759 of an entry formal appearing in an assignment statement does not assign
10761 (Expand_Current_Value): Instead of calling a routine to determine
10762 whether the prefix of an attribute reference should be optimized or
10763 not, prevent the optimization of such prefixes all together.
10765 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10766 component whose prefix is known to be of an access type is an implicit
10767 dereference and does not assign to the prefix.
10769 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10770 Robert Dewar <dewar@adacore.com>
10772 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10773 itype is visited, make an entry into table to link associated node and
10775 Add comments and correct harmless error in Build_NCT_Hash_Tables
10776 (Array_Aggr_Subtype): Associate each itype created for an index type to
10777 the corresponding range construct, and not to the aggregate itself. to
10778 maintain a one-to-one correspondence between itype and its associated
10779 node, to prevent errors when complex expression is copied.
10780 Fix mishandling of multiple levels of parens
10782 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10783 treatment of limited views uniform for all visible declarations in a
10784 limited_withed package.
10785 (New_Copy_Tree): If hash table is being used and itype is visited,
10786 make an entry into table to link associated node and new itype.
10787 (Resolve_Record_Aggregate): Do not add an others box association for a
10788 discriminated record component that has only discriminants, when there
10789 is a box association for the component itself.
10791 * par-ch4.adb: Fix mishandling of multiple levels of parens
10793 2007-08-14 Robert Dewar <dewar@adacore.com>

10838 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10839 generation of a freezing node to ensure proper management of null
10840 excluding access types in the backend.
10841 (Create_Extra_Formals): Test base type of the formal when checking for
10842 the need to add an extra accessibility-level formal. Pass the entity E
10843 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10844 originally being done in a couple of cases), to ensure that the
10845 Extra_Formals list gets set on the entity E when the first entity is
10847 (Conforming_Types): Add missing calls to Base_Type to the code that
10848 handles anonymous access types. This is required to handle the
10849 general case because Process_Formals builds internal subtype entities
10850 to handle null-excluding access types.
10851 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10852 functions that need it, even when not marked Requires_Overriding.
10853 Improve warnings for in out parameters
10854 (Analyze_Function_Return): Warn for disallowed null return
10855 Warn on return from procedure with unset out parameter
10856 Ensure consistent use of # in error messages
10857 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10858 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10859 the implicit conversion of the expression done for anonymous access
10860 types. This is required to generate the code of the null excluding
10861 check (if required).
10863 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10864 A formal parameter is never publicly referenceable outside of its body.
10865 (Check_References): For an unreferenced formal parameter in an accept
10866 statement, use the same warning circuitry as for subprogram formal
10868 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10869 Output_Unreferenced_Messages, containing the part of that routine that
10870 is now reused for entry formals as described above.
10871 (Goto_Spec_Entity): New function
10872 (Check_References): Do not give IN OUT warning for dispatching operation
10873 Improve warnings for in out parameters

10880 Javier Miranda <miranda@adacore.com>
10881 Gary Dismukes <dismukes@adacore.com>
10883 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10884 (Expand_N_Attribute_Reference): Further unify the handling of the
10885 three forms of access attributes, using common code now for all three
10886 cases. Add a test for the case of applying an access attribute to
10887 an explicit dereference when the context is an access-to-interface
10888 type. In that case we need to apply the conversion to the prefix
10889 of the explicit dereference rather than the prefix of the attribute.
10890 (Attribute_Version, UET_Address): Set entity as internal to ensure
10891 proper dg output of implicit importation.
10892 (Expand_Access_To_Type): Removed.
10893 (Expand_N_Attribute_Reference): Merge the code from the three cases
10894 of access attributes, since the processing is largely identical for
10895 these cases. The substantive fix here is to process the case of a
10896 type name prefix (current instance case) before handling the case
10897 of interface prefixes.

10901 Javier Miranda <miranda@adacore.com>
10902 Robert Dewar <dewar@adacore.com>
10904 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10905 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10906 type that is an anonymous access to controlled object, establish
10907 an associated finalization chain to avoid corrupting the global
10908 finalization list when a dynamically allocated object designated
10909 by such a component is deallocated.
10910 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10911 functions that need it, even when not marked Requires_Overriding.
10912 (Initialize_Tag): Replace call to has_discriminants by call to
10913 Is_Variable_Size_Record in the circuitry that handles the
10914 initialization of secondary tags.
10915 (Is_Variable_Size_Record): New implementation.
10916 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10917 Suppress_Initialization pragma for a derived type.
10918 (Is_Variable_Size_Record): New subprogram.
10919 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10920 initial version of this routine and also fixes problems causing
10921 incomplete initialization of the table of interfaces.
10922 (Build_Init_Procedure): Improve the generation of code to initialize the
10923 the tag components of secondary dispatch tables.
10924 (Init_Secondary_Tags): New implementation that simplifies the previous
10925 version of this routine.
10926 (Make_DT): Add parameter to indicate when type has been frozen by an
10927 object declaration, for diagnostic purposes.
10928 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10929 diagnose attemps to freeze a subprogram when some untagged type of its
10930 profile is a private type whose full view has not been analyzed yet.
10931 (Freeze_Array_Type): Generate init proc for packed array if either
10932 Initialize or Normalize_Scalars is set.
10933 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10934 constructing the new profile, copy the null_exclusion indicator for each
10935 parameter, to ensure full conformance of the new body with the spec.
10937 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10938 Create wrappers for constructor functions that need it, even when not
10939 marked Requires_Overriding.
10940 (Covers): Handle properly designated types of anonymous access types,
10941 whose non-limited views are themselves incomplete types.
10942 (Add_Entry): Use an entity to store the abstract operation which hides
10944 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

10946 initialization aggregate.
10947 (Function_Interp_May_Be_Hidden): Rename to
10948 Function_Interp_Has_Abstract_Op.
10949 (Has_Compatible_Type): Remove machinery that skips interpretations if
10950 they are labeled as potentially hidden by an abstract operator.
10951 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10952 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10953 (Write_Overloads): Output the abstract operator if present.
10954 (Add_Entry): Before inserting a new entry into the interpretation table
10955 for a node, determine whether the entry will be disabled by an abstract

10958 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10960 (Function_Interp_May_Be_Hidden): New routine.
10961 (Has_Compatible_Type): Do not consider interpretations hidden by
10962 abstract operators when trying to determine whether two types are
10964 (Has_Hidden_Interp): New routine.
10965 (Set_May_Be_Hidden_Interp): New routine.
10966 (Write_Overloads): Write the status of flag May_Be_Hidden.

10972 types declared in the declarative part of a nested package body or in
10973 the proper body of a stub.
10974 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10975 of the same dispatch table slot to renamed primitives.
10976 (Make_Select_Specific_Data_Table): Handle private types.
10977 (Tagged_Kind): Handle private types.
10978 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10979 output of implicit importation and exportation.
10980 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10981 first formal of the thunk is always associated with the controlling
10982 type. In addition perform the following code cleanup: remove formal
10983 Thunk_Alias which is no longer required, cleanup evaluation of the
10984 the controlling type, and update the documentation.
10985 Replace occurrence of Default_Prim_Op_Count by
10986 Max_Predef_Prims. Addition of compile-time check to verify
10987 that the value of Max_Predef_Prims is correct.
10988 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10989 (Make_DT): Add parameter to indicate when type has been frozen by an
10990 object declaration, for diagnostic purposes.
10991 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10992 construction of statically allocated dispatch tables.
10993 (Make_DT): In case of library-level tagged types export the declaration
10994 of the primary tag. Remove generation of tags (now done by Make_Tags).
10995 Additional modifications to handle non-static generation of dispatch
10996 tables. Take care of building tables for asynchronous interface types
10997 (Make_Tags): New subprogram that generates the entities associated with
10998 the primary and secondary tags of Typ and fills the contents of Access_
10999 Disp_Table. In case of library-level tagged types imports the forward
11000 declaration of the primary tag that will be declared later by Make_DT.
11001 (Expand_Interface_Conversion): In case of access types to interfaces
11002 replace an itype declaration by an explicit type declaration to avoid
11003 problems associated with the scope of such itype in transient blocks.

11006 Ed Schonberg <schonberg@adacore.com>
11007 Javier Miranda <miranda@adacore.com>
11009 * exp_util.ads, exp_util.adb:
11010 This patch replaces a number of occurrences of explicit tests for N_Null
11011 with calls to Known_Null. This improves tracking of null values, since
11012 Known_Null also catches null constants, and variables currently known to
11013 be null, so we get better tracking.
11014 (Ensure_Defined): create an itype reference only in the scope of the
11016 (Side_Effect_Free): A selected component of an access type that
11017 denotes a component with a rep clause must be treated as not
11018 side-effect free, because if it is part of a linked structure its
11019 value may be affected by a renaming.
11020 (Expand_Subtype_From_Expr): For limited objects initialized with build
11021 in place function calls, do nothing; otherwise we prematurely introduce
11022 an N_Reference node in the expression initializing the object, which
11023 breaks the circuitry that detects and adds the additional arguments to
11024 the called function. Bug found working in the new patch for statically
11025 allocated dispatch tables.
11026 (Is_Library_Level_Tagged_Type): New subprogram.
11027 (Remove_Side_Effects): If the expression of an elementary type is an
11028 operator treat as a function call.
11029 (Make_Literal_Range): If the index type of the array is not integer, use
11030 attributes properly to compute the constraint on the resulting aggregate
11033 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11034 class-wide type whose base type is an incomplete private type, leave
11035 class-wide type unfrozen so that freeze nodes can be generated
11036 properly at a later point.
11037 (Freeze_Entity, array case): Handle case of pragma Pack and component
11038 size attributre clause for same array.

11095 attribute Body in package Naming. Do not replace a source/unit in the
11096 same project when the order of the source dirs are known. Detect
11097 duplicate sources/units in the same project when the order of the
11098 source dirs are not known.
11099 (Check_Ada_Name): Allow all identifiers that are not reserved words
11101 Major update of the Project Manager and of the project aware tools,
11102 including gprmake, so that the same sources in the GNAT repository
11103 can be used by gprbuild.

11105 directory of non extending project to nil.
11106 Change type of path name variables to be Path_Name_Type
11107 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

12986 overloading cases, when several ancestors may have class-wide operations

13001 (Mark_Allocator): An allocator with a discriminant association parent is
13003 (Try_One_Prefix_Interpretation): If the type of the object is
13004 incomplete, as can be happen when it is a limited view obtained through
13005 a limited_with_clause, the selected component is not part of a prefixed
13007 (Complete_Object_Operation): Diagnose properly an object that is not
13008 aliased when the corresponding controlling formal is an access
13010 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13011 ambiguous calls in prefixed notation, where two primitives differ only
13012 in that the controlling argument of one is an access parameter.
13014 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13015 whether a function that returns an unconstrained type can be inlined.
13016 (Process_Formals): Diagnose properly the illegal use of an incomplete
13017 type in the profile of an access_to_subprogram declaration.
13018 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13019 operations are attached to the corresponding record.
13020 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13021 When processing a primitive of a concurrent type which implements an
13022 interface change the type of all controlling formals to that of the
13023 corresponding record type.
13024 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13025 to determine the tagged type to which a primitive belongs.
13026 (Check_Conventions): Capture condition to ignore a primitive operation
13027 (which is shared between the loop in Check_Conventions and the one in
13028 Check_Convention) in a new local function Skip_Check.
13029 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13030 confusion with Check_Conventions' own Prim_Op local variable.
13031 (Create_Extra_Formals): Test for a tagged result type rather than a
13032 controlling result when determining whether to add a BIP_Alloc_Form
13033 formal and a BIP_Final_List formal to the function.
13034 (Check_Conformance); For parameters that are anonymous access types,
13035 subtype conformance requires that the not null and the constant
13036 indicators must match
13037 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13038 to retrieve the appropriate type when processing a concurrent type
13039 declared within a generic. Minor comment reformatting. Change invocation
13040 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13042 (Analyze_Subprogram_Body): If the return type of a function is an
13043 anonymous access to the limited view of a class-wide type, and the
13044 non-limited view of the type is available, update the type of the
13045 function so that code can be generated.
13046 (Process_Formals): In case of access-subtype itype whose designated
13047 type is also an itype (situation that happens now with access to
13048 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13049 attribute to avoid backend problems.
13050 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13051 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13052 anonymous types' designated types are same before testing
13053 Subtypes_Statically_Match.
13054 (Create_Extra_Formals): Test for a named access parameter that is a
13055 controlling formal as an additional condition for adding an
13056 accessibility level formal. This can occur in the subp type created for
13057 dispatching calls in Expand_Dispatching_Call, and allows calling
13058 Create_Extra_Formals from that procedure rather than special-casing the
13059 extra formals there.
13060 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13061 when the function has a controlling result.
13062 (Check_Returns): Add much more knowledge of the optimization of local
13063 raise statements to gotos, to retain proper warnings in this case.
13064 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13065 nodes when looking for last statement.
13067 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13068 class-wide types visible through limited with clauses.
13069 (Add_One_Interp): If the operands are anonymous access types, the
13070 predefined operator on universal_access is immediately visibles
13071 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13072 other anonymous access types.
13073 (Disambiguate): Take into account CIL convention.
13074 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13076 2007-06-06 Robert Dewar <dewar@adacore.com>
13078 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13079 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13080 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13081 Fix lower bound of tables.
13084 * nlists.adb: Ditto.
13085 (Prev_Node, Next_Node): Change index type to Int so that it properly
13086 covers the range First_Node_Id - 1 up.
13088 2007-06-06 Javier Miranda <miranda@adacore.com>
13089 Ed Schonberg <schonberg@adacore.com>
13090 Bob Duff <duff@adacore.com>
13091 Hristian Kirtchev <kirtchev@adacore.com>
13093 * exp_aggr.ads, exp_aggr.adb:
13094 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13095 in extension aggregates.
13096 (Flatten): Other conditions being met, an aggregate is static if the
13097 low bound given by component associations is different from the low
13098 bound of the base index type.
13099 (Packed_Array_Aggregate_Handled): If the component type is itself a
13100 packed array or record, the front-end must expand into assignments.
13101 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13102 Init_Pr, instead of Ancestor_Is_Expression.
13103 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13104 coextension chain root, either generate a list controller or use the
13105 already existing one.
13106 (Static_Array_Aggregate): New procedure to construct a positional
13107 aggregate that can be handled by the backend, when all bounds and
13108 components are compile-time known constants.
13109 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13110 types covering interface types into assignments.
13111 (Replace_Type): move to Build_Record_Aggr_Code.
13112 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13113 interface type, convert to the definite type of the aggregate itself,
13114 so that needed components are visible.
13115 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13116 components and the context is an extended return statement do not
13117 create a transient block for it, to prevent premature finalization
13118 before the return is executed.
13119 (Gen_Assign): Do not generate a call to deep adjust routine if the
13120 component type is itself an array of controlled (sub)-components
13121 initialized with an inner aggregate.
13122 (Component_Check): New name for Static_Check. This name is now more
13123 appropriate, and documentation is added which was missing.
13124 (Component_Check): Add test for bit aligned component value
13125 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13126 Tagged_Comps, name is more appropriate given added function below.
13127 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13129 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13130 Javier Miranda <miranda@adacore.com>
13131 Robert Dewar <dewar@adacore.com>
13133 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13134 Terminated: Add unchecked type conversion from System.Address to
13135 System.Tasking.Task_Id when calling the predefined primitive
13137 Disable new Ada 05 accessibility check for JVM.NET targets, which
13138 cannot be implemented in a practical way.
13139 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13140 the sources always references the tag of the actual object. Therefore,
13141 if 'Tag is applied in the sources to class-wide interface objects we
13142 generate code that displaces "this" to reference the base of the object.
13143 (Expand_N_Attribute_Reference, case Size): Return specified size if
13144 known to front end.
13145 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13146 has code that displaces the pointer of the object to manage interface
13147 types. However this code must not be executed when the prefix is a
13148 subprogram. This bug caused the wrong expansion of the internally
13149 generated assignment that fills the dispatch table when the primitive
13150 is a function returning a class-wide interface type.
13151 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13152 Set_Attribute_Name for Name_Unaligned_Valid.
13154 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13155 Gary Dismukes <dismukes@adacore.com>
13157 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13158 If the initialization is the equivalent aggregate of the initialization
13159 procedure of the type, do not remove it.
13160 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13161 initialized to null from having their expression reset to empty and
13162 note this exception in the comment.
13164 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13165 Robert Dewar <dewar@adacore.com>
13166 Ed Schonberg <schonberg@adacore.com>
13167 Gary Dismukes <dismukes@adacore.com>
13169 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13170 Add "with" and "use" clauses for Sem_Attr.
13171 (Expand_Current_Value): Do not replace occurences of attribute
13172 references where the prefix must be a simple name.
13174 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13175 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13176 Attribute_Requires_Simple_Name_Prefix.
13177 (Name_Modifies_Prefix): Body of new function.
13178 (Requires_Simple_Name_Prefix): Body of new function.
13179 (Resolve_Attribute, case Access): Improve error message for case of
13180 mismatched conventions.
13181 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13183 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13184 constrained subtype for a nominal unconstrained type, use its base type
13185 to check for conformance with the context.
13186 (Resolve_Attribute): Remove test of the access type being associated
13187 with a return statement from condition for performing accessibility
13188 checks on access attributes, since this case is now captured by
13189 Is_Local_Anonymous_Access.
13190 (Analyze_Access_Attribute): Set Address_Taken on entity
13191 (Analyze_Attribute, case Address): Set Address_Taken on entity
13192 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13193 validating an access attribute whose prefix is a current instance.
13194 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13195 applied to dispatching operations, if freezing is required then we set
13196 the attribute Has_Delayed_Freeze in the prefix's entity.
13197 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13198 current scope if access of local subprogram taken
13199 (Analyze_Access_Attribute): Check legality of self-reference even if the
13200 expression comes from source, as when a single component association in
13201 an aggregate has a box association.
13202 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13203 the prefix if it is a protected operation and the attribute is
13204 Unrestricted_Access.
13205 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13206 reference to the base type of the context, to force a constraint check
13207 when the context is an access subtype with an explicit constraint.
13208 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13209 node is rewritten as an interface conversion. leave unanalyzed after
13210 resolution, to ensure that type checking against the context will take

13214 Javier Miranda <miranda@adacore.com>
13215 Robert Dewar <dewar@adacore.com>
13217 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13218 wrapper when the full view of the controlling type of an inherited
13219 function that dispatches on result implements interfaces.
13220 (Expand_N_Object_Declaration): In cases where the type of the
13221 declaration is anonymous access, create finalization list for it.
13222 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13223 if the object has no explicit initialization, to match description of
13224 functionality of pragam Persistent_BSS.
13225 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13226 new function to build static aggregates, to replace initialization call
13227 when static initialization is desired.
13228 (Freeze_Type): Generate a list controller for an access type whenever
13229 its designated type has controlled anonymous access discriminants.
13230 (Build_Equivalent_Aggregate): New procedure to compute a static
13231 aggregate to be used as default initialization for composite types,
13232 instead of a generating a call to the initialization procedure for the
13234 (Build_Initialization_Call): When available, replace a call to the
13235 initialization procedure with a copy of the equivalent static aggregate
13237 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13238 declarations for objects of a class-wide interface type, rather than
13239 just identifiers, to prevent visibility problems.
13240 (Expand_N_Object_Declaration): When expanding the declaration for an
13241 object of a class-wide interface type, preserve the homonym chain of
13242 the original entity before exchanging it with that of the generated
13243 renaming declaration.
13244 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13245 active, because there is no way to handle the exception.
13246 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13247 to do a minimum decoration of the Access_Disp_Table list.
13248 (Expand_Record_Controller): Avoid the addition of the controller between
13249 the component containing the tag of a secondary dispatch table and its
13250 adjacent component that stores the offset to the base of the object.
13251 This latter component is only generated when the parent type has
13252 discriminants ---documented in Add_Interface_Tag_Components).
13253 (Apply_Array_Size_Check): Removed, no longer needed.
13254 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13255 components, create a Master_Entity for it only if it contains tasks.
13256 (Build_Init_Procedure): Suppress the tag assignment compiling under
13258 (Freeze_Record_Type): Remove code associated with creation of dispatch
13260 (Init_Secondary_Tags): Update type of actuals when generating calls to
13261 Ada.Tags.Set_Offset_To_Top
13262 (Stream_Operation_OK): Disable use of streams compiling under no
13264 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13265 if Has_Init_Expression set.
13266 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13267 Register_Primitive, which provides the same functionality.
13268 (Requires_Init_Proc): Return false in case of interface types.
13269 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13271 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13272 is always associated with a predefined primitive because the internal
13273 entities associated with interface types are not predefined primitives.
13274 Therefore, the call to Is_Internal is replaced by a call to the
13275 function Is_Predefined_Dispatching_Operation.
13276 (Make_Eq_If): When generating the list of comparisons for the
13277 components of a given variant, omit the controller component that is
13278 present if the variant has controlled components.
13280 2007-06-06 Javier Miranda <miranda@adacore.com>
13281 Hristian Kirtchev <kirtchev@adacore.com>
13282 Bob Duff <duff@adacore.com>
13284 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13285 handle the creation of finalization lists and calls for nested
13286 coextensions when the root of the chains is part of a return statement.
13287 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13289 (Expand_Record_Equality): Skip components that are interface types.
13290 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13291 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13292 with Rewrite_Coextension. Change the condition for detecting coextension
13294 (Is_Local_Access_Discriminant): Removed.
13295 (Rewrite_Coextension): New routine which rewrites a static coextension
13296 as a temporary and uses its unrestricted access in the construction of
13298 (Complete_Coextension_Finalization): New routine. Generate finalization
13299 attachment calls to all delayed coextensions.
13300 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13301 the allocator is not a coextension itself and has delayed coextensions.
13302 If the current allocator is controlled, but also a coextension, delay
13303 the generation of the finalization attachment call.
13304 Rename local variable "Node" to "Nod" in order to avoid confusion with
13306 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13307 limited types that are not inherently limited. Such an allocator is
13308 illegal, but is generated by the expander for a return statement, to
13309 copy the result onto the secondary stack. This is the only case where a
13310 limited object can be copied. Generate code to displace the pointer
13311 to the object if the qualified expression is a class-wide interface
13312 object. Such displacement was missing and hence the copy of the object
13314 (Apply_Accessibility_Check): Handle allocated objects initialized in
13316 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13317 and Expand_Allocator_Expression. Allocating class-wide interface objects
13318 this routine displaces the pointer to the allocated object to reference
13319 the component referencing the corresponding secondary dispatch table.
13320 Expand_Allocator_Expression): Add missing support to allocate class-wide
13321 interface objects initialized with a qualified expression.
13322 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13323 function result type, and use the finalization list associated with the
13324 function scope in that case (such an anonymous type should not be
13325 treated like an access parameter's type).
13327 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13328 Gary Dismukes <dismukes@adacore.com>
13329 Javier Miranda <miranda@adacore.com>
13331 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13332 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13333 required exception handler.
13334 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13335 properly the case of a function whose return type is a limited
13336 class-wide interface type. Modify the code of the accessibility
13337 check to handle class-wide interface objects. In this case we need to
13338 displace "this" to reference the primary dispatch table to get access
13339 to the TSD of the object (to evaluate its accessibility level).
13340 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13341 rather than a controlling result as one of the conditions for
13342 generating tests of the implicit BIP_Alloc_Form formal. The
13343 initialization assignment is also handled according to whether the
13344 result is tagged instead of controlling.
13345 In the case where the init assignment is inserted in the "then" part of
13346 the allocation conditional, rewrite the target to be a dereference of
13347 the implicit BIP_Object_Access formal.
13348 If the returned value is unconstrained and created on the secondary
13349 stack, mark the enclosing block and function so that the secondary
13350 stack is not reclaimed on return.
13351 Treat returns from functions with controlling results similarly to
13352 returns from functions with unconstrained result subtypes.
13353 If the object returned is unconstrained, and an allocator must be
13354 created for it, analyze the allocator once the block for the extended
13355 return is installed, to ensure that finalizable components
13356 of the expression use the proper finalization list. Guard the call to
13357 Move_Final_List with a check that there is something to finalize.
13358 (Make_Tag_Ctrl_Assignment): Use "old" handling
13359 of controlled type assignment for virtual machines, since new code uses
13360 unsupported features (such as direct access to bytes in memory).
13362 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13363 Ed Schonberg <schonberg@adacore.com>
13365 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13366 accessibility actual, check for the case of an aliased object that has
13367 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13368 we fall into processing for the attribute rather than the name of the
13370 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13371 formal has its address taken in the body, create a temporary to capture
13372 value. If the return type is a limited interface, do not treat the
13373 return value as Controlled.
13374 (Is_In_Place_Function): If the return type is a limited interface,
13375 treat as returning in place. The actual returned object may not always
13376 be limited, but the caller has to assume that it is returned in place.
13377 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13378 context of an allocator, use the correct finalization chain (that is,
13379 the chain belonging to the access type, rather than the chain belonging
13380 to the current scope).
13381 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13382 result type rather than a controlling result as a precondition for
13383 adding an allocation form actual to a build-in-place call.
13384 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13385 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13386 primitive in the dispatch tables. This work is now done by Make_DT when
13387 the type is frozen.
13388 (Register_Predefined_DT_Entry): Removed.
13389 (Add_Return): If end label is not present, use sloc of last statement
13390 for generated return statement in procedure, for better gdb behavior
13392 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13393 object address nodes to ensure proper processing by routines like
13395 (Expand_Call): Fix generation of validity check for parameter
13396 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13397 the allocation form parameter if the result subtype is constrained,
13398 except when the function has a controlling result.
13399 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13400 rather than Is_Controlled and Has_Controlled_Component, since we want to
13401 include class-wide result types in this treatment. Also test for a
13402 controlling result, since that also requires passing a finalization
13404 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13405 even when the result subtype is constrained, to handle calls involving
13406 controlling results.
13407 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13408 is now called even when the result subtype is constrained, to handle
13409 calls involving controlling results.
13410 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13411 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13412 now performs the test).
13413 (Make_Build_In_Place_Call_In_Object_Declaration):
13414 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13415 constrained, to handle calls involving controlling results.
13416 (Add_Return): Accomodate rewritten pattern from local raise to goto
13417 transformation, so that we still recognize an transfer statement
13418 and do the right thing here in that case.
13419 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13420 and end of subprogram code.
13421 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13422 support for primitives that are functions (without formals) with a

13440 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13441 appears in the optional statement list of a triggering alternative, the
13442 scope actions can be inserted directly there, and not in the list that

13474 functionality when the backend is generating code.
13475 Otherwise any serious error
13476 reported by the backend calling the frontend routine Error_Msg

13518 deallocation of class-wide interface objects.
13519 (Expand_Dispatching_Constructor_Call): Take into account that if the
13520 result of the dispatching constructor is an interface type, the
13521 function returns a class-wide interface type; otherwise the returned
13522 object would be actual. The frontend previously accepted returning
13523 interface types because Expand_Interface_Actuals silently performed
13524 the management of the returned type "as if" it were a class-wide
13526 (Expand_Dispatching_Constructor_Call): Replace call to
13527 Make_DT_Access_Action by direct call to Make_Function_Call.

13619 subtype from the function call, as is done for private types.
13620 (Side_Effect_Free): An expression that is the renaming of an object or
13621 whose prefix is the renaming of a object, is not side-effect free
13622 because it may be assigned through the renaming and its value must be

13736 defined in GNAT.IO, which might not be stdout
13737 (Is_Valid): Adjust comment to mention that a positive reply means that
13738 Header_Of may be used to retrieve the allocation header associated with

15248 (Resolve_Call): If the call returns an array, the context imposes the
15249 component type of the array, and the function has one non-defaulted
15250 parameter, rewrite the call as the indexing of a call with a single
15251 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15253 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15254 the master of the created object is the innermost enclosing statement.
15255 (Remove_Conversions): For a binary operator, check if type of second
15256 formal is numeric, to check if an abstract interpretation is present
15257 in the case of exponentiation as well.

15288 object of a null-excluding access type then don't require the
15289 the object declaration to have an expression and don't emit a

15352 (E_Return_Statement): This node type has the Finalization_Chain_Entity
15353 attribute, in case the result type has controlled parts.
15354 (Requires_Overriding): Add this new flag, because "requires
15355 overriding" is subtly different from "is abstract" (see AI-228).
15356 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15357 Is_Abstract_Type. Make sure these are called only when appropriate.

15391 (Expand_Inlined_Call): If the subprogram is a null procedure, or a
15392 stubbed procedure with a null body, replace the call with a null
15393 statement without using the full inlining machinery, for efficiency
15394 and to avoid invalid values in source file table entries.

15419 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15420 "abstract subprograms must be visible" message, whether or not the type
15421 is an interface; that is, remove the special case for interface types.

15447 build-in-place functions with result type with controlled parts.
15448 Remove no longer used entities.
15450 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no
15451 longer needed, because the full type is now limited, and therefore a

15453 (Foreign_Task_Level): New constant.
15455 * s-tassta.ads, s-tassta.adb (Move_Activation_Chain): New procedure to

15484 to handle properly the anonymous access case.
15486 * sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
15487 for all access attributes, because overload resolution should work the
15488 same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This

15498 attempt to derive from a synchronized tagged type.
15499 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15500 type, inherit the class-wide type already created, because it may
15501 already have been used in a self-referential anonymous access component.
15502 (Mentions_T): Recognize self-referential anonymous access components
15503 that use (a subtype of) the class-wide type of the enclosing type.
15504 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15505 Derived_Type for Prev formal on call to
15506 Check_Anonymous_Access_Components rather than Empty.
15507 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15508 a record extension in deciding whether to create a class-wide type,

15556 (Compile): When compiling a predefined source, add -gnatpg
15557 as the second switch, after -c.

15562 gnatbind if the ALI file effectively exists.
15563 (Initialize): Add the directory where gnatmake is invoked in front of
15564 the path if it is invoked from a bin directory, even without directory

15589 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15590 when -gnatg is not specified.
15591 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15592 there is no need to generate always a record_definition_node in case
15593 of synchronized interface types.

15641 succeed in that case, even when the expression originates from a
15642 parameter of the containing subprogram.
15643 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15644 under No_Dispatching_Calls restriction. During the semantic analysis
15645 we already notified such violation.

15663 initialize most the TSD components by means of an aggregate.
15664 Modify the declaration of the object containing the TSD
15665 because we now expand code that has a higher level of abstraction.
15666 The TSD has a discriminant containing the Inheritance Depth Level,

15697 (Expand_Dispatching_Call): Replace generation of call to the run-time
15698 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15699 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15701 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15702 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15716 check violation of restriction No_Dispatching_Calls.
15717 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15724 specify Any_Limited_Interface, and this functionality is already
15725 provided by the function Has_Abstract_Interfaces.
15726 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15727 support concurrent types implementing interfaces.
15728 (Find_Implemented_Interface): Removed. All the calls to this subprogram

15746 Cyrille Comar <comar@adacore.com>
15748 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15749 anonymous, use finalization list of enclosing dynamic scope.
15750 (Expand_N_Package_Declaration): For a library package declaration
15751 without a corresponding body, generate RACW subprogram bodies in the
15752 spec (just as we do for the task activation call).
15753 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15754 Is_Abstract_Type. Make sure these are called only when appropriate.
15755 Remove all code for DSP option
15756 (CW_Or_Controlled_Type): new subprogram.

15760 Gary Dismukes <dismukes@adacore.com>
15762 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15763 parameter. If it is set to true, return a result capped according to
15764 the global upper bound for the index of an entry family.

15770 is potentially large.
15771 (Build_Entry_Count_Expression): If the family is potentially large, call
15772 Family_Size with 'Cap' set to true.
15773 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15774 a protected version of an operation declared in the private part of
15775 a protected object, because they may be invoked through a callback.
15776 (Set_Privals): If the type of a private component is an anonymous access
15777 type, do not create a new itype for each protected body.
15778 If the body of a protected operation creates
15779 controlled types (including allocators for class-widetypes), the
15780 body of the corresponding protected subprogram must include a
15782 (Build_Activation_Chain_Entity): Build the chain entity for extended
15784 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15785 to determine whether operation overrides an inherited primitive.

15787 for a possible overriding candidate.
15788 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15789 hold an actual parameter value since its initialization is separated

15793 2007-04-06 Thomas Quinot <quinot@adacore.com>
15794 Pablo Oliveira <oliveira@adacore.com>
15796 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15797 Do an Unchecked_Conversion to handle the passage from the Underlying
15798 Type to the Base Type when calling Build_To_Any_Call and
15799 Build_From_Any_Call.
15800 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15801 E_Constant, depending upon Variable formal.
15802 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15803 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15804 parameter that requires an extra constrained parameter, declare
15805 temporary for actual as a variable, not a constant.
15806 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15807 the unit being compiled is the one that contains the stub type.
15808 Change primitive operation name for the RACW associated with a RAS
15809 from Call to _Call so it cannot clash with any legal identifier.
15810 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15812 (Append_RACW_Bodies): New subprogram.
15813 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15814 Add_Receiving_Stubs_To_Declarations functions.
15815 When expanding a package body, this list correspond to the
15816 statements in the HSS at the end of the pacakge.
15817 When expanding a package spec, this list correspond to the
15819 (Add_Receiving_Stubs_To_Declarations): Append the function
15820 registering the receiving stubs at the end of the 'Stmts' list.
15821 (RCI_Package_Locator): Pass the new Version generic formal when
15822 instantiating a RCI_Locator package.
15823 (Build_From_Any_Function): To compute the High bound for an
15824 unconstrained array actual, we add the Low bound with the length.
15825 Thus we must convert the low bound and the length to an appropriate
15826 type before doing the sum.
15827 (Build_Subprogram_Receiving_Stubs, PolyORB):
15828 * Retrieve the extra formals parameters at the
15829 end of the parameter stream.
15830 * Use Move_Any_Value to write back out parameters
15831 after executing the request as it is more efficient
15832 than Copy_Any_Value.
15833 * Build the any containing Extra Formals with the
15834 appropriate typecode.
15835 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15836 empty Component_List.
15837 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15838 the tree the declaration for an object that serves as actual parameter
15839 in server-side stubs.
15840 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15841 PolyORB_Support.Build_Subprogram_Receiving_Stubs):

15849 function with the first not implicit parent type.
15850 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15851 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15852 typecode from the Etype. Therefore we retrieve the correct typecode
15853 with a call to Get_Any_Type.
15854 (Copy_Specification): Do controlling formal type substitution based on
15855 Is_Controlling_Formal flag, instead of caller-provided object type.
15856 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15857 a RACW primitive operation, we might get a subprogram declaration for an
15858 ancestor of the RACW designated type (not for the designated type
15859 itself), in the case where this operation is inherited. In this case we
15860 have no easy means of determining the original tagged type for which
15861 the primitive was declared, so instead we now rely on
15862 Copy_Specification to use the Is_Controlling_Formal flag to determine
15863 which formals require type substitution.

15869 GNAT.Current_Exception are not allowed if pragma Restrictions
15870 (No_Exception_Propagation) is set and in any case make the associated
15871 handler unsuitable as a target for a local raise statement.
15872 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15873 run-time subprogram CW_Membership by call to Build_CW_Membership.
15874 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15875 by a function call, a temporary must be created before expanding the
15876 Constructor_Call itself, to prevent out-of-order elaboration in the
15877 back-end when stack checking is enabled..
15879 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15881 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15882 result are the bounds of the left operand, not the right.
15884 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15887 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15899 box corresponds to a component of the type.
15900 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15901 Is_Abstract_Subprogram and Is_Abstract_Type.

16006 standard 8bits encoding.
16007 (WS2SU): As above but converting from wide-sring to string.
16008 This is needed as it is necessary to have access to both versions in the
16009 runtime for the form parameter encoding support.
16010 This set of patch add support for the encoding form parameter.
16011 (S2WS): Improve implementation to handle cases where the filename is not
16012 UTF-8 encoded. In this case we default to using the current code page
16013 for the conversion.

16060 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16061 __gnat_adjust_context_for_raise.
16062 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16063 implementation of floating point operations as native x86 targets.
16064 So the FPU should be initialized in the same way using finit. Fix
16065 floating point operations accuracy issues.

16134 2007-04-06 Robert Dewar <dewar@adacore.com>
16136 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16137 it no longer destroys the contents of Name_Buffer or Name_Len and
16138 non-standard and invalid names are handled better.
16139 (Get_Decoded_Name_String): Improve performance by using
16140 Name_Has_No_Encodings flag in the name table.

16148 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16149 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16150 there is no need to generate always a record_definition_node in case
16151 of synchronized interface types.
16152 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16153 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16154 illegal in Ada 95, in cases where it is legal. Change the warnings to
16155 errors in other cases. Don't give the error unless the "not null"
16156 parses properly. Correct the source position at which the error occurs.
16157 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16158 P_Null_Exclusion, to suppress "not null" warnings.

16210 Entry for pragma Unreferenced_Objects
16212 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16213 switches, without repetition of "eD". Make sure that last character of
16214 -gnatep= switch is not taken as -gnat switch character.
16215 Complete rewrite of circuit for handling saving compilation options

16234 the default project path, initially done during elaboration of the
16236 If the prefix returned by Sdefault is null, get the prefix from a call
16237 to Executable_Prefix_Path.
16238 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16241 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16242 canonical directory name to open the directory from which files are
16244 (Record_Other_Sources): Idem.
16245 (Locate_Directory): Add the possibility to create automatically missing
16246 directories when Setup_Projects is True.

16249 library source copy dir and exec dir.
16251 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16254 2007-04-06 Robert Dewar <dewar@adacore.com>

16289 full word is no longer compared twice.
16291 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16293 * sem_ch10.adb (Install_Limited_Context_Clauses.
16294 Expand_Limited_With_Clause): Use a new copy of selector name in the
16295 call to Make_With_Clause. This fixes the tree structure for ASIS
16296 purposes. Nothing is changed in the compiler behaviour.
16297 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16298 a package renaming.
16299 (Install_Limited_With_Clauses): Do not install non-limited view when it
16300 is still incomplete.
16302 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16303 Gary Dismukes <dismukes@adacore.com>
16305 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16306 when capturing size information, instead of base type, which for a
16307 formal array type will be the unconstrained type.
16308 (Analyze_Formal_Object_Declaration): Add check for illegal default
16309 expressions for a formal in object of a limited type.
16310 (Instantiate_Object): Ditto.
16311 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16312 because they were defaulted in the formal package and no check applies
16314 (Check_Formal_Package_Instance): Extend conformance check to other
16315 discrete types beyond Integer.
16316 (Process_Default): Copy directly the unmatched formal. A generic copy
16317 has already been performed in Analyze_Formal_Package.
16318 (Analyze_Associations): If a formal subprogram has no match, check for
16319 partial parametrization before looking for a default, to prevent
16321 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16322 not set the instantiation environment before analyzing the actuals.
16323 Fixes regression on 8515-003 with implementation of AI-133.
16324 Set_Instance_Env checks whether the generic unit is a predefined
16325 unit, in which case the instance must be analyzed with the latest Ada
16326 mode. This setting must take place after analysis of the actuals,
16327 because the actuals must be analyzed and frozen in the Ada mode extant
16328 outside of the current instantiation.
16329 (Save_Env, Restore_Env): Preserve and restore the configuration
16330 parameters so that predefined units can be compiled in the proper Ada
16332 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16333 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16334 and Is_Abstract_Type.
16335 (Analyze_Formal_Package): For better error recovery, Add exception
16336 handler to catch Instantion_Error, which can be raised in
16337 Analyze_Associations
16339 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16340 Bob Duff <duff@adacore.com>
16341 Gary Dismukes <dismukes@adacore.com>
16343 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16344 prefix type is a discriminated subtype of the type of the formal.
16345 (Analyze_Allocator): Collect all coextensions regardless of the context.
16346 Whether they can be allocated statically is determined in exp_ch4.
16347 (Analyze_Selected_Component): If the prefix is a limited view and the
16348 non-limited view is available, use the non-limited one.
16349 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16350 therefore illegal), suggest a qualified expression rather than a type
16351 conversion, because a type conversion would be illegal in this context.
16352 (Anayze_Allocator): Trace recursively all nested allocators so that all
16353 coextensions are on the corresponding list for the root. Do no mark
16354 coextensions if the root allocator is within a declaration for a stack-
16355 allocated object, because the access discriminants will be allocated on
16357 (Analyze_Call): Remove restriction on calls to limited functions for the
16358 cases of generic actuals for formal objects, defaults for formal objects
16359 and defaults for record components.
16360 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16361 element list. Their expansion is delayed until the enclosing allocator
16362 is processed and its finalization list constructed.
16363 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16364 for an operation with the given name among the primitive operations of
16365 the corresponding record type.
16366 (Analyze_Selected_Component): If the prefix is a task type that
16367 implements an interface, and there is no entry with the given name,
16368 check whether there is another primitive operation (e.g. a function)
16370 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16371 properly the indexing of a function call written in prefix form, where
16372 the function returns an array type, and all parameters of the function
16373 except the first have defaults.
16374 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16375 the original operands, rather than relocating them, for efficiency and
16376 to work properly when an operand is overloaded.
16377 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16378 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16379 (Analyze_Selected_Component): If the prefix is a private extension, only
16380 scan the visible components, not those of the full view.
16381 (Try_Primitive_Operation): If the operation is a procedure, collect all
16382 possible interpretations, as for a function, because in the presence of
16383 classwide parameters several primitive operations of the type can match
16384 the given arguments.
16386 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16387 Robert Dewar <dewar@adacore.com>
16389 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16390 tag-indeterminate call to an abstract function, when the left-hand side
16392 (Analyze_Loop_Statement): Improve detection of infinite loops
16394 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16395 Thomas Quinot <quinot@adacore.com>
16397 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16398 out of Analyze_Package_Declaration, because processing must be applied
16399 to package bodies as well, for deferred constants completed by pragmas.
16400 (Analyze_Package_Declaration): When the package declaration being
16401 analyzed does not require an explicit body, call Check_Completion.
16402 (May_Need_Implicit_Body): An implicit body is required when a package
16403 spec contains the declaration of a remote access-to-classwide type.
16404 (Analyze_Package_Body): If the package contains RACWs, append the
16405 pending subprogram bodies generated by exp_dist at the end of the body.
16406 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16407 Is_Abstract_Subprogram and Is_Abstract_Type.
16408 (Preserve_Full_Attributes): The full entity list is not an attribute
16409 that must be preserved from full to partial view.
16411 * sem_dist.adb (Add_RAS_Dereference_TSS):
16412 Change primitive name to _Call so it cannot clash with any legal
16413 identifier, and be special-cased in Check_Completion.
16414 Mark the full view of the designated type for the RACW associated with
16415 a RAS as Comes_From_Source to get proper view switching when installing
16416 private declarations.
16417 Provite a placeholder nested package body along with the nested spec
16418 to have a place for Append_RACW_Bodies to generate the calling stubs
16419 and stream attributes.
16421 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16422 Robert Dewar <dewar@adacore.com>
16424 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16425 that is a limited view, check the non-limited view if available.
16426 (Undefined): Refine error message for missing with of Text_IO
16427 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16428 to distinguish real missing with cases.
16429 Fix format of all missing with messages
16430 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16431 renaming as body when renamed entity is abstract.
16433 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16434 Javier Miranda <miranda@adacore.com>
16436 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16437 predicate recursive, to handle complex expressions on literals whose
16438 spurious ambiguity comes from the abstract interpretation of some
16440 (Interface_Present_In_Ancestor): Add support to concurrent record
16442 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16443 Is_Abstract_Subprogram and Is_Abstract_Type.
16445 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16446 Javier Miranda <miranda@adacore.com>
16448 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16449 dereference of a local object R created as a reference to another
16450 object O, use the access level of O.
16451 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16452 rather than local Same_Formal_Type, to check whether protected operation
16453 overrides an inherited one.
16454 (Same_Formal_Type): New predicate, used when matching signatures of
16455 overriding synchronized operations, to handle the case when a formal
16456 has a type that is a generic actual.
16457 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16458 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16459 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16460 syntactic ambiguities involving indexing of function calls that return
16462 (Abstract_Interface_List): New subprogram that returns the list of
16463 abstract interfaces associated with a concurrent type or a
16464 concurrent record type.
16465 (Interface_Present_In_Parent): New subprogram used to check if a
16466 given type or some of its parents implement a given interface.
16467 (Collect_Abstract_Interfaces): Add support for concurrent types
16468 with interface types.
16469 (Has_Abstract_Interfaces): Add support for concurrent types with
16471 (Is_Parent): New subprogram that determines whether E1 is a parent
16472 of E2. For a concurrent type its parent is the first element of its
16473 list of interface types; for other types this function provides the
16474 same result than Is_Ancestor.
16475 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16476 (Collect_Synchronized_Interfaces): Removed because the subprogram
16477 Collect_Abstract_Interfaces provides this functionality.
16478 (Collect_Abstract_Interfaces): Minor update to give support to
16479 concurrent types and thus avoid undesired code duplication.
16480 (Get_Subprogram_Entity): Handle entry calls.
16481 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16483 (Enter_Name): Do not give -gnatwh hiding warning for record component
16484 entities, they never result in hiding.

16489 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
16490 to chain nested components that are allocators for access discriminants
16491 of the enclosing object.
16492 Add N_Push and N_Pop nodes
16493 New field Exception_Label added
16494 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16495 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
16496 (Is_Coextension): New flag for allocators, to mark allocators that
16497 correspond to access discriminants of dynamically allocated objects.
16498 (N_Block_Statement): Document the fact that the corresponding entity
16499 can be an E_Return_Statement.
16500 (Is_Coextension): New flag for allocators.
16501 Remove all code for DSP option
16503 * sprint.ads, sprint.adb: Display basic information for class_wide
16504 subtypes. Add handling of N_Push and N_Pop nodes

16508 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16509 before propagating exception.
16511 2007-04-06 Olivier Hainque <hainque@adacore.com>
16513 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16514 an address always within the call instruction from a return address.
16516 2007-04-06 Olivier Hainque <hainque@adacore.com>
16517 Eric Botcazou <botcazou@adacore.com>
16519 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16520 expression with a COMPOUND_EXPR including the call instead of emitting
16521 the call directly here.
16522 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16523 high bound is constant and the slice is empty. Tidy.
16524 (tree_transform, case N_Op_Not): Handle properly the case where the
16525 operation applies to a private type whose full view is a modular type.
16526 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16527 Address_Clause, use the associated Expression as the GNAT tree
16528 representing the choice value to ensure the corresponding GCC tree is
16529 of the proper kind.
16530 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16531 instead of just the operands, as the base GCC stabilize_reference does.
16532 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16533 requested; otherwise fail.
16534 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16536 2007-04-06 Thomas Quinot <quinot@adacore.com>
16538 * uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
16539 implementation of UI_Div.
16540 (UI_Div): Reimplement as a call to UI_Div_Rem.
16541 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16542 remainder, avoiding the cost of a multiplication and a subtraction.
16543 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16544 provides both quotient and remainder in a single computation.
16545 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16546 functions for uint.
16547 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16548 is undefined if the given n is not inversible.
16550 2007-04-06 Olivier Hainque <hainque@adacore.com>
16552 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
16553 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion
16556 2007-04-06 Eric Botcazou <botcazou@adacore.com>
16557 Olivier Hainque <hainque@adacore.com>
16559 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16560 when updating the contents of the old pointer to an unconstrained array.
16561 (end_subprog_body): Set error_gnat_node to Empty.
16562 (write_record_type_debug_info): Do not be unduly sparing with our bytes.
16563 (unchecked_convert): For subtype to base type conversions, require that
16564 the source be a subtype if it is an integer type.
16565 (builtin_decls): New global, vector of available builtin functions.
16566 (gnat_pushdecl): Add global builtin function declaration nodes to the
16567 builtin_decls list.
16568 (gnat_install_builtins): Adjust comments.
16569 (builtin_function): Set DECL_BUILTIN_CLASS and DECL_FUNCTION_CODE before

16814 anonymous access types.
16815 (Valid_Conversion): For a conversion to a numeric type occurring in an
16816 instance or inlined body, no need to check that the operand type is

16873 zone data and calculate the GMT offset.

17522 the parent part is a build-in-place function call, generate assignments.
17523 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17524 are build-in-place function calls.
17525 (Replace_Self_Reference): New subsidiary of
17526 Make_OK_Assignment_Statement, to replace an access attribute that is a
17527 self-reference into an access to the appropriate component of the
17528 target object. Generalizes previous mechanism to handle self-references
17529 nested at any level.
17530 (Is_Self_Referential_Init): Remove, not needed.
17531 (Is_Self_Referential_Init): New predicate to simplify handling of self
17532 referential components in record aggregates.
17533 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17534 check for presence of entity before checking for self-reference.
17535 (Has_Default_Init_Comps): Return True if a component association is a
17536 self-reference to the enclosing type, which can only come from a
17537 default initialization.
17538 (Make_OK_Assignment_Statement): If the expression is of the form
17539 Typ'Acc, where Acc is an access attribute, the expression comes from a
17540 default initialized self-referential component.
17541 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17542 that has been derived from several abstract interfaces we must also
17543 initialize the tags of the secondary dispatch tables.

17548 Robert Dewar <dewar@adacore.com>
17551 (Expand_Access_To_Protected_Op): If the context indicates that an access
17552 to a local operation may be transfered outside of the object, create an
17553 access to the wrapper operation that must be used in an external call.
17554 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17555 target, pass the Valid attribute applied to a floating-point prefix on
17556 to the back end without expansion.
17557 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17558 the allocated storage when it is specified by a per-object expression.
17559 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17560 Nothing to do here, the attribute has been rewritten during semantic
17562 (Expand_Attribute_Reference): Handle expansion of the new Priority
17564 (Find_Fat_Info): Handle case of universal real
17565 (Expand_Access_To_Protected_Op): Fix use of access to protected
17566 subprogram from inside the body of a protected entry.
17567 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17568 'Access and 'Unrestricted_Access, to transform the attribute reference
17569 into a fat pointer.
17570 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17571 subcomponent's enclosing variable is aliased with a constrained subtype.
17572 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17573 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17574 an aliased prefix must be known to be constrained in order to use True
17575 for the attribute value, and now it's possible for some aliased views
17576 to be unconstrained.
17578 2006-10-31 Robert Dewar <dewar@adacore.com>
17580 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17581 (Expand_Entity_Reference): Correct error of not handling subprogram
17582 formals in current_value processing.

17587 Gary Dismukes <dismukes@adacore.com>
17589 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17590 register in the final list objects containing class-wide interfaces;
17591 otherwise we incorrectly register the tag of the interface in the final
17593 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17594 generate the wrapper if the parent primitive is abstract. This is
17595 required to report the correct error message.
17596 (Expand_N_Subtype_Indication): Do validity checks on range
17597 (Clean_Task_Names): If an initialization procedure includes a call to
17598 initialize a task (sub)component, indicate that the procedure will use
17599 the secondary stack.
17600 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17601 compatibility for interfacing with CPP by default.
17602 (Expand_N_Object_Declaration): Only build an Adjust call when the
17603 object's type is a nonlimited controlled type.
17604 * exp_ch3.adb: Add with and use of Exp_Ch6.
17605 (Expand_N_Object_Declaration): Check for object initialization that is a
17606 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17607 Object_Declaration to the call.
17608 (Freeze_Type): When the designated type of an RACW was not frozen at the
17609 point where the RACW was declared, validate the primitive operations
17610 with respect to E.2.2(14) when it finally is frozen.
17611 (Build_Initialization_Call,Expand_Record_Controller): Rename
17612 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17613 return-by-reference has no meaning in Ada 2005.
17614 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17615 to register tag of the immediate ancestor interfaces in the
17616 run-time structure.
17617 (Init_Secondary_Tags): Moved to the specification to allow the
17618 initialization of extension aggregates with abstract interfaces.
17619 (Build_Master_Renaming): Make public, for use by function declarations
17620 whose return type is an anonymous access type.
17621 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17622 Insert_List_Before_And_Analyze after the generation of the specs
17623 associated with null procedures.
17624 (Expand_Tagged_Root): Update documentation in its specification.
17625 (Init_Secondary_Tags): Update documentation.
17626 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17627 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17628 then generate code to inherit the contents of the dispatch table
17629 directly from the ancestor.
17630 (Expand_Record_Controller): Insert controller component after tags of
17631 implemented interfaces.
17632 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17633 create null procedure overridings when null procedures are inherited
17635 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17636 declarations for overriding null primitives inherited from interfaces.
17637 (Is_Null_Interface_Procedure): New function in
17638 Make_Null_Procedure_Specs.
17639 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17640 immediate ancestor of a tagged type is an abstract interface type we
17641 must generate the specification of the predefined primitives associated
17642 with controlled types (because the dispatch table of the ancestor is
17643 null and hence these entries cannot be inherited). This is required to
17644 elaborate well the dispatch table.

17652 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17654 (Expand_N_In): Do validity checks on range
17655 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17656 (Expand_N_Allocator): For "new T", if the object is constrained by
17657 discriminant defaults, allocate the right amount of memory, rather than
17658 the maximum for type T.
17659 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17660 when the allocator is initialized by a build-in-place call, since the
17661 allocator is already rewritten as a reference to the function result,
17662 and this prevents an unwanted duplication of the function call.
17663 Add with and use of Exp_Ch6.
17664 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17665 is a call to build-in-place function and apply
17666 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17667 untagged designated types).
17668 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17669 optimization if source or target is biased.
17670 (Expand_N_Allocator): Add comments for case of an allocator within a
17671 function that returns an anonymous access type designating tasks.
17672 (Expand_N_Allocator): apply discriminant checks for access
17673 discriminants of anonymous access types (AI-402, AI-416)

17680 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17682 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17683 (Expand_N_Assignment_Statement): Call
17684 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17685 build-in-place function call. Currently, this can happen only for
17686 assignments that come from aggregates.
17687 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17688 in order to alleviate the upward compatibility introduced by AI-318.
17689 (Expand_N_Extended_Return_Statement): Add support for handling the
17690 return object as a build-in-place result.
17691 (Expand_Non_Function_Return): Implement simple return statements nested
17692 within an extended return.
17693 (Enable_New_Return_Processing): Turn on the new processing of return
17695 (Expand_Non_Function_Return): For a return within an extended return,
17696 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17697 (Expand_N_Extended_Return_Statement): Implement AI-318
17698 (Expand_Simple_Function_Return): Ditto.
17699 (Expand_N_If_Statement): Handle new -gnatwt warning
17700 (Expand_N_Case_Statement): Handle new -gnatwt warning
17701 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17702 a protected object.
17703 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17704 validity checking of assignments to elementary record components.
17705 (Expand_N_Return_Statement): return Class Wide types on the secondary
17706 stack independantly of their controlled status since with HIE runtimes,
17707 class wide types are not potentially controlled anymore.
17709 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17712 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17713 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17714 it expects a block, procedure, or task. The return statement will get
17715 turned into a block, and Expand_Cleanup_Actions will happen then.

17719 Bob Duff <duff@adacore.com>
17720 Gary Dismukes <dismukes@adacore.com>
17722 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17724 (Expand_Inlined_Call): Tagged types are by-reference types, and
17725 therefore should be replaced by a renaming declaration in the expanded
17726 body, as is done for limited types.
17727 (Expand_Call): If this is a call to a function with dispatching access
17728 result, propagate tag from context.
17729 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17731 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17732 build-in-place when the right-hand side of an assignment is a
17733 build-in-place function call.
17734 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17735 of the explicit dereference of the allocator to the result subtype of
17736 the build-in-place function. This is needed to satisfy type checking
17737 in cases where the caller's return object is created by an allocator for
17738 a class-wide access type and the type named in the allocator is a
17740 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17741 conversion of the reference to the declared object to the result subtype
17742 of the build-in-place function. This is needed to satisfy type checking
17743 in cases where the declared object has a class-wide type. Also, in the
17744 class-wide case, change the type of the object entity to the specific
17745 result subtype of the function, to avoid passing a class-wide object
17746 without explicit initialization to the back end.
17747 (Register_Interface_DT_Entry): Moved outside the body of
17748 Freeze_Subprogram because this routine is now public; it is called from
17749 Check_Dispatching_Overriding to handle late overriding of abstract
17750 interface primitives.
17751 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17752 adding an implicit access actual on a call to a build-in-place function.
17753 (Expand_Actuals): Test for an actual parameter that is a call to a
17754 build-in-place function and apply
17755 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17756 (Is_Build_In_Place_Function): New function to determine whether an
17757 entity is a function whose calls should be handled as build-in-place.
17758 (Is_Build_In_Place_Function_Call): New function to determine whether an
17759 expression is a function call that should handled as build-in-place.
17760 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17761 calls to build-in-place functions as the initialization of an allocator.
17762 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17763 handling calls to build-in-place functions in contexts that do not
17764 involve init of a separate object (for example, actuals of subprogram
17766 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17767 handling calls to build-in-place functions as the initialization of an
17768 object declaration.
17769 (Detect_Infinite_Recursion): Add explicit parameter Process to
17770 instantiation of Traverse_Body to avoid unreferenced warning.
17771 (Check_Overriding_Inherited_Interfaces): Removed.
17772 (Register_Interface_DT_Entry): Code cleanup.
17773 (Register_Predefined_DT_Entry): Code cleanup.
17774 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17775 inlined statements if within a transient scope.
17776 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17777 formal parameters with occurrences of actuals in inlined body, establish
17778 visibility on the proper view of the actual's subtype for the body's
17780 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17781 compatibility mode and we have an imported CPP subprogram because
17782 for now we assume that imported CPP primitives correspond with
17783 objects whose constructor is in the CPP side (and therefore we
17784 don't need to generate code to register them in the dispatch table).
17785 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17786 aligned selected component.
17787 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17788 the actual of an in-mode parameter is a type conversion.
17789 (Expand_Actuals): If the call does not come from source and the actual
17790 is potentially misaligned, let gigi handle it rather than rejecting the
17791 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17792 Class Wide types as returning by reference independantly of their
17793 controlled status since with HIE runtimes class wide types are not
17794 potentially controlled anymore.
17796 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17798 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17799 references that are private components of the protected object.
17800 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
17801 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17802 instantiation to deal with warnings.
17803 (Initialize_Protection): If expression for priority is non-static, use
17804 System_Priority as its expected type, in case the expression has not

17809 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17810 initialization of Homonym_Len.
17811 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17812 names from fully qualified name. Fixes problem of duplicate
17813 external names differing only in the presence of such a block name.
17815 2006-10-31 Thomas Quinot <quinot@adacore.com>
17816 Pablo Oliveira <oliveira@adacore.com>
17818 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17819 subprogram Ids, even if they are not yet assigned.
17820 (Build_Subprogram_Id): It is now this function that will take care of
17821 calling Assign_Subprogram_Ids if necessary.
17822 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17823 should be done only once they are assigned.
17824 (Build_From_Any_Function, case of tagged types): Add missing call to
17826 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17827 type for an RACW type.
17828 (Add_RACW_Features): When processing an RACW declaration for which the
17829 designated type is already frozen, enforce E.2.2(14) rules immediately.
17830 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17831 special reordering of controlling formals.
17833 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17834 associated stub type for an RACW type.
17836 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17838 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17839 fixed-point operations in an integer context, i.e. as operands of a
17840 conversion to an integer type, indicate that result must be rounded.
17842 2006-10-31 Robert Dewar <dewar@adacore.com>
17844 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17845 cases, pass the encoding method, since it is now required by the run
17848 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17849 assumption that Str'First = 1.
17850 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17851 it on to the Value_Wide_Wide_Character call.
17852 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17853 properly handles a string of the form quote-encoded_wide_char-quote.
17855 * s-wchcnv.adb: Minor reformatting
17857 2006-10-31 Javier Miranda <miranda@adacore.com>
17859 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17860 run-time membership test to ensure that the constructed object
17861 implements the target abstract interface.
17863 2006-10-31 Robert Dewar <dewar@adacore.com>
17865 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17866 Machine_Attribute pragma internally to implement the user pragma.
17867 Add processing for pragma Interface so that it is now completely
17868 equivalent to pragma Import.
17870 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17871 so that it can be applied to all entities, including record components
17872 and enumeration literals.
17873 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17874 priority ranges are correct, verify compatibility against task
17875 dispatching and locking policies, and if everything is correct an entry
17876 is added to the table containing priority specific dispatching entries
17877 for this compilation unit.
17878 (Delay_Config_Pragma_Analyze): Delay processing
17879 Priority_Specific_Dispatching pragmas because when processing the
17880 pragma we need to access run-time data, such as the range of
17881 System.Any_Priority.
17882 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17883 Allow pragma Unreferenced as a context item
17884 Add pragma Preelaborable_Initialization

17886 now syntactically and semantically equivalent to Import.
17887 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17888 insertion characters.
17889 Add handling for Pragma_Wide_Character_Encoding
17890 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17891 never supercedes a real restriction, and that a real restriction
17892 always supercedes a warning.
17893 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17898 Robert Dewar <dewar@adacore.com>
17900 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17901 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17902 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17904 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17905 type of the function containing a return statement, because the
17906 Return_Type field was removed. We now use the Return_Applies_To field.
17908 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17909 (Build_Task_Image_Decl): If procedure is not called from an
17910 initialization procedure, indicate that function that builds task name
17911 uses the sec. stack. Otherwise the enclosing initialization procedure
17912 will carry the indication.
17913 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17914 N_Object_Declaration instead.
17915 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17916 conditional dead code killed, and change implementation accordingly.
17917 (Insert_Actions): Add N_Return_Object_Declaration case.
17918 Correct comment to mention N_Extension_Aggregate node.
17919 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17920 attempts to save information for global variables which cannot be
17922 (Get_Current_Value_Condition): Handle conditions the other way round
17923 (constant on left). Also handle right operand of AND and AND THEN
17924 (Set_Current_Value_Condition): Corresponding changes
17925 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17926 (Get_Current_Value_Condition): Handle simple boolean operands
17927 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17928 (Get_Current_Value_Condition): If the variable reference is within an
17929 if-statement, does not appear in the list of then_statments, and does
17930 not come from source, treat it as being at unknown location.
17931 (Get_Current_Value_Condition): Enhance to allow while statements to be
17932 processed as well as if statements.
17933 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17935 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17936 of loop. This is safe now that we fixed Kill_Current_Values.
17937 (OK_To_Do_Constant_Replacement): Check whether current scope is
17938 Standard, before examining outer scopes.
17940 2006-10-31 Vincent Celier <celier@adacore.com>
17942 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17943 When True, apply VMS treatment to children of packages A, G, I and S.
17946 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17948 2006-10-31 Robert Dewar <dewar@adacore.com>
17949 Ed Schonberg <schonberg@adacore.com>
17951 * freeze.adb: Add handling of Last_Assignment field
17952 (Warn_Overlay): Supply missing continuation marks in error msgs
17953 (Freeze_Entity): Add check for Preelaborable_Initialization
17955 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17957 * g-expect.adb: Add Warnings (Off) to prevent new warning
17959 * lib-xref.adb: Add handling of Last_Assignment field
17960 (Generate_Reference): Centralize handling of pragma Obsolescent here
17961 (Generate_Reference): Accept an implicit reference generated for a
17962 default in an instance.
17963 (Generate_Reference): Accept a reference for a node that is not in the
17964 main unit, if it is the generic body corresponding to an subprogram
17967 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17969 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17971 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17973 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17974 use clauses, to avoid messages on packages used to qualify, and also
17975 to avoid messages from obsolescent units.
17976 (Warn_On_Useless_Assignments): Don't generate messages for imported
17977 and exported variables.
17978 (Warn_On_Useless_Assignments): New procedure
17979 (Output_Obsolescent_Entity_Warnings): New procedure
17980 (Check_Code_Statement): New procedure
17982 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

17984 (Last_Assignment): New field for useless assignment warning
17986 2006-10-31 Olivier Hainque <hainque@adacore.com>
17988 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17989 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17991 2006-10-31 Bob Duff <duff@adacore.com>
17992 Robert Dewar <dewar@adacore.com>
17993 Ed Schonberg <schonberg@adacore.com>
17995 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17996 Ada 95 mode, because it violates the new rules for AI-318.
17998 * g-awk.ads: Use overloaded subprograms in every case where we used to
17999 have a default of Current_Session. This makes the code closer to be
18000 correct for both Ada 95 and 2005.
18002 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18003 code, relying on the fact that the compiler generates a warning
18004 instead of an error in -gnatg mode.
18006 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18007 E_Return_Statement entity kind.
18008 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18010 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18011 report an error if the reserved word abstract has been previously found.
18012 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18014 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18015 parenthesized range attribute usage
18016 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18018 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18019 in the syntax for extended_return_statement. This is not in the latest
18020 RM, but the ARG is expected to issue an AI allowing this.
18021 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18022 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18023 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18024 P_Return_Statement): Parse the new syntax for extended_return_statement.
18026 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18027 Output_End_Missing): Add error-recovery code for the new
18028 extended_return_statement syntax; that is, the new E_Return entry on
18031 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18032 limited to nonlimited, because otherwise we violate the new Ada 2005
18033 rules about returning limited types in function Create_AST_Handler in
18036 * sem.adb (Analyze): Add cases for new node kinds
18037 N_Extended_Return_Statement and N_Return_Object_Declaration.
18039 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18040 type is in the same category as type of context before applying check,
18041 to prevent anomalies in instantiations.
18042 (Resolve_Aggregate): Remove test for limited components in aggregates.
18043 It's unnecessary in Ada 95, because if it has limited components, then
18044 it must be limited. It's wrong in Ada 2005, because limited aggregates
18046 (Resolve_Record_Aggregate): Move check for limited types later, because
18047 OK_For_Limited_Init requires its argument to have been resolved.
18048 (Get_Value): When copying the component default expression for a
18049 defaulted association in an aggregate, use the sloc of the aggregate
18050 and not that of the original expression, to prevent spurious
18051 elaboration errors, when the expression includes function calls.
18052 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18053 were missing. We also didn't handle qualified expressions. Now also
18054 allow function calls. Use new common routine OK_For_Limited_Init.
18055 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18056 with space can upper case letter).
18058 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18059 Has_Static_Discriminants flag
18060 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18061 type with discriminants.
18062 (Process_Range_Expr_In_Decl): Do validity checks on range
18063 (Build_Discriminant_Constraints): Use updated form of
18064 Denotes_Discriminant.
18065 (Process_Subtype): If the subtype is a private subtype whose full view
18066 is a concurrent subtype, introduce an itype reference to prevent scope
18068 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18069 Record_Type_Declaration): The functionality of the subprograms
18070 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18071 is now performed by a single routine.
18072 (Build_Derived_Record_Type): If the type definition includes an explicit
18073 indication of limitedness, then the type must be marked as limited here
18074 to ensure that any access discriminants will not be treated as having
18075 a local anonymous access type.
18076 (Check_Abstract_Overriding): Issue a detailed error message when an
18077 abstract subprogram was not overridden due to incorrect mode of its
18079 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18080 synchronized private extension declarations. Verify that the ancestor is
18081 a limited or synchronized interface or in the generic case, the ancestor
18082 is a tagged limited type or synchronized interface and all progenitors
18083 are either limited or synchronized interfaces.
18084 Derived_Type_Declaration): Check for presence of private extension when
18085 dealing with synchronized formal derived types.
18086 Process_Full_View): Enchance the check done on the usage of "limited" by
18087 testing whether the private view is synchronized.
18088 Verify that a synchronized private view is completed by a protected or
18090 (OK_For_Limited_Init_In_05): New function.
18091 (Analyze_Object_Declaration): Move check for limited types later,
18092 because OK_For_Limited_Init requires its argument to have been resolved.
18093 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18094 in order to alleviate the upward compatibility introduced by AI-318.
18095 (Constrain_Corresponding_Record): If the constraint is for a component
18096 subtype, mark the itype as frozen, to avoid out-of-scope references to
18097 discriminants in the back-end.
18098 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18099 this subprogram against wrong sources.
18100 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18101 discriminant of limited type completed with a protected type, when the
18102 discriminant is used to constrain a private component of the type, and
18103 expansion is disabled.
18104 (Find_Type_Of_Object): Do not treat a return subtype that is an
18105 anonymous subtype as a local_anonymous_type, because its accessibility
18106 level is the return type of the enclosing function.
18107 (Check_Initialization): In -gnatg mode, turn the error "cannot
18108 initialize entities of limited type" into a warning.
18109 (OK_For_Limited_Init): Return true for generated nodes, since it
18110 sometimes violates the legality rules.
18111 (Make_Incomplete_Declaration): If the type for which an incomplete
18112 declaration is created happens to be the currently visible entity,
18113 preserve the homonym chain when removing it from visibility.
18114 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18115 inherited subprograms.
18116 (Access_Definition): If this is an access to function that is the return
18117 type of an access_to_function definition, context is a type declaration
18118 and the scope of the anonymous type is the current one.
18119 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18120 incomplete subtype to the set of private dependents of the original
18122 (Constrain_Discriminated_Type): Emit an error message whenever an
18123 incomplete subtype is being constrained.
18124 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18125 corresponding subtype of the full view of the original incomplete type.
18126 (Check_Incomplete): Properly detect invalid usage of incomplete types
18129 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18131 * g-catiio.ads, g-catiio.adb (Value): New function.

18140 Robert Dewar <dewar@adacore.com>
18142 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18143 handling executable extension manually and duplicating code.
18145 * make.adb: Implement new -S switch
18146 (Gnatmake): Use new function Osint.Executable_Name instead
18147 of handling executable extension manually.
18149 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18150 is specified, the executable name ends with this suffix.
18151 Take advantage of Osint.Executable_Name instead of duplicating code.
18153 * switch-m.adb: Recognize new gnatmake -S switch
18155 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18157 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18160 * makeusg.adb: Add line for gnatmake -S switch
18162 2006-10-31 Vincent Celier <celier@adacore.com>
18164 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18165 call it with -static-libgcc, as there are some platforms, such as
18166 Darwin, where one of these two switches is compulsory to link.
18168 2006-10-31 Vincent Celier <celier@adacore.com>
18170 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18171 instead of ADA_PROJECT_PATH, for the project path.
18172 (Gnatls): When displaying the project path directories, use host dir
18175 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18176 names in the project path, as absolute paths may correspond to
18177 multi-valued VMS logical names.
18179 2006-10-31 Vincent Celier <celier@adacore.com>
18181 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18182 absolute path name.
18183 (Locate_Regular_File): Ditto
18184 (Change_Dir): Remove, no longer used
18185 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18186 on Windows. Get it calling Get_Current_Dir.
18187 (OpenVMS): Remove imported boolean, no longer needed.
18188 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18189 (Pid_To_Integer): New function to convert a Process_Id to Integer
18191 2006-10-31 Thomas Quinot <quinot@adacore.com>
18193 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18194 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18196 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18199 2006-10-31 Robert Dewar <dewar@adacore.com>
18201 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18202 initial letter o as a zero.

18208 2006-10-31 Robert Dewar <dewar@adacore.com>
18210 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18212 (Layout_Variant_Record): Retrieve the discriminants from the entity
18213 rather than from the type definition, because in the case of a full
18214 type for a private type we need to take the discriminants from the
18216 (Layout_Component_List): When applying the Max operator to variants with
18217 a nonstatic size, check whether either operand is static and scale that
18218 operand from bits to storage units before applying Max.
18219 (Layout_Type): In VMS, if a C-convention access type has no explicit
18220 size clause (and does not inherit one in the case of a derived type),
18221 then the size is reset to 32 from 64.
18223 2006-10-31 Vincent Celier <celier@adacore.com>
18225 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18226 its file has already been loaded, according to the unit being loaded,
18227 not to the current value of Multiple_Unit_Index.
18229 2006-10-31 Thomas Quinot <quinot@adacore.com>
18230 Eric Botcazou <ebotcazou@adacore.com>

18257 * mlib-utl.adb (Initialized): Remove, no longer used
18258 (Initialize): Remove, no longer used
18259 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18260 if there is one, the archive indexer. Fail if the archive builder cannot
18262 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18265 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18267 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18268 Process_Body_Clauses): If the context of a body includes a use clause
18269 for P.Q then a with_clause for P in the same body is not redundant,
18270 even if the spec also has a with_clause on P.
18271 Add missing continuation mark to error msg
18272 (Build_Limited_Views): A limited view of a type is tagged if its
18273 declaration includes a record extension.
18274 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18275 node, even if the subunit has errors. This avoids malfunction by
18276 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18277 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18278 generation of obsolescent messages for with statements (cannot do
18279 this too early, or we cannot implement avoiding the messages in the
18280 case of obsolescent units withing obsolescent units).
18281 (Install_Siblings): If the with_clause is on a remote descendant of
18282 an ancestor of the current compilation unit, find whether there is
18283 a sibling child unit that is immediately visible.
18284 (Remove_Private_With_Clauses): New procedure, invoked after completing
18285 the analysis of the private part of a nested package, to remove from
18286 visibility the private with_clauses of the enclosing package
18288 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18289 now centralized in Generate_Reference.
18290 (Install_Limited_Context_Clauses): Remove superfluous error
18291 message associated with unlimited view visible through use
18292 and renamings. In addition, at the point in which the error
18293 is reported, we add the backslash to the text of the error
18294 to ensure that it is reported as a single error message.
18295 Use new // insertion for some continuation messages
18296 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18297 to create implicit with_clause for parent unit mentioned in original
18298 limited_with_clause.
18299 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18300 unit is a child unit. For ASIS queries.
18301 (Analyze_Subunit): If the subunit appears within a child unit, make all
18302 ancestor child units directly visible again.

18317 a formal object declaration with an access definition or a subtype mark
18318 with a null exclusion.
18319 (P_Generic_Association): Handle association with box, and others_choice
18320 with box, to support Ada 2005 partially parametrized formal packages.
18322 2006-10-31 Robert Dewar <dewar@adacore.com>
18323 Javier Miranda <miranda@adacore.com>
18325 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18326 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18327 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18328 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18329 private extensions.
18330 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18331 to P_Interface_Type_Definition.
18332 (P_Interface_Type_Definition): Addition of one formal to report an error
18333 if the reserved word abstract has been previously found.
18334 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18335 object renaming declaration with an access definition or subtype mark
18336 with a possible null exclusion.
18338 * par-ch9.adb: Minor error msg fix
18340 * par-load.adb: Add missing continuation mark to error msg

18360 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18361 on VMS, change "__" to '.' before checking the name.
18362 (Record_Ada_Source): Always add the source file name in the list of
18363 of sources, even if it is not the first time, as it is for another
18365 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18366 dot, instead of replacing only the first '_'.
18368 * prj-part.adb (Parse): Convert project file path to canonical form
18370 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18371 extended, the project id of the project extending it is recorded in its
18372 data, even when it has already been processed as an imported project.
18374 2006-10-31 Robert Dewar <dewar@adacore.com>

18380 Robert Dewar <dewar@adacore.com>
18382 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18383 only a restriction warning is active for the given restriction. This is
18384 desirable because we do not want to modify code in the case where only
18386 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18387 causes overriding of real restrictions.
18388 Take advantage of new No_Restrictions constant.
18390 * raise.h: (__gnat_set_globals): Change profile.
18392 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18394 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18397 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18398 Move all the entities in obsolete package System.PolyORB_Interface to
18399 System.Partition_Interface.

18417 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18418 properly an attempt to apply Unchecked_Access to a protected operation.
18419 (OK_Self_Reference): New subprogram to check the legality of an access
18420 attribute whose prefix is the type of an enclosing aggregate.
18421 Generalizes previous mechanism to handle attribute references nested
18422 arbitrarily deep within the aggregate.
18423 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18424 can appear in an aggregate if this is a default-initialized aggregate
18425 for a self-referential type.
18426 (Resolve_Attribute, case Access): Ditto.
18427 Add support for new implementation defined attribute Stub_Type.

18429 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18430 (Stream_Attribute_Available): Implement using new subprogram from
18431 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18432 Has_Specified_Stream_Attribute flag.
18433 Disallow Storage_Size and Storage_Pool for access to subprogram
18434 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18435 access types of return subtypes in extended return statements. Remove
18436 accessibility checks on anonymous access types when Unchecked_Access is
18438 (Analyze_Attribute): Add support for the use of 'Class to convert
18439 a class-wide interface to a tagged type.
18440 Add support for the attribute Priority.
18441 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18442 whether the designated type is discriminated with a constrained partial
18443 view and require static matching in that case.
18444 Add local variable Des_Btyp. The Designated_Type
18445 of an access to incomplete subtype is either its non-limited view if
18446 coming from a limited with or its etype if regular incomplete subtype.
18448 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18449 Fix predicate to identify and allow cases of (expander-generated)
18450 references to tag of designated object of a RACW.
18451 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18452 non-static, and therefore cannot appear as a primary in a preelaborable
18454 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18455 Has_Read_Write_Attributes.
18456 (Has_Read_Write_Attributes): Reimplement in termes of
18457 Has_Stream_Attribute_Definition.
18458 (Missing_Read_Write_Attributes): When checking component types in a
18459 record, unconditionally call Missing_Read_Write_Attributes recursively
18460 (remove guard checking for Is_Record_Type / Is_Access_Type).
18462 2006-10-31 Robert Dewar <dewar@adacore.com>
18464 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18465 useless assignments here and conditionalize it on absence of exception
18467 (Analyze_Exception_Handlers): Small code reorganization of error
18468 detection code, for new handling of formal packages.
18470 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18471 Hristian Kirtchev <kirtchev@adacore.com>
18473 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18474 that has been constant-folded, preserve information of original tree,
18476 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18477 generated private extension declaration if the formal derived type is
18478 synchronized. Carry synchronized present over to the generated private
18480 (Validate_Derived_Type_Instance): Ensure that the actual of a
18481 synchronized formal derived type is a synchronized tagged type.
18482 (Instantiate_Formal_Package): When creating the instantiation used to
18483 validate the actual package of a formal declared without a box, check
18484 whether the formal itself depends on a prior actual.
18485 (Instantiate_Formal_Subprogram): Create new entities for the defining
18486 identifiers of the formals in the renaming declaration, for ASIS use.
18487 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18488 a renaming declaration or a subtype declaration for an actual in an
18489 instance, capture location information of declaration in generic, for
18491 (Instantiate_Formal_Package): Add comments on needed additional tests.
18492 AI-317 (partial parametrization) is fully implemented.
18493 (Validate_Private_Type_Instance): Add check for actual which
18494 must have preelaborable initialization
18495 Use new // insertion for some continuation messages
18496 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18497 Default_Expression. Add type retrieval when the declaration has an
18498 access definition. Update premature usage of incomplete type check.
18499 (Check_Access_Definition): New subsidiary routine. Check whether the
18500 current compilation version is Ada 05 and the supplied node has an
18502 (Instantiate object): Alphabetize local variables. Handle the creation
18503 of new renaming declarations with respect to the kind of definition
18504 used - either an access definition or a subtype mark. Guard against
18505 unnecessary error message in the context of anonymous access types after
18506 they have been resolved. Add check for required null exclusion in a
18507 formal object declaration.
18508 (Switch_View): A private subtype of a non-private type needs to be
18509 switched (the base type can have been switched without its private
18510 dependents because of the last branch of Check_Private_View.
18511 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18513 (Instantiate_Type): Emit an error message whenever a class-wide type of
18514 a tagged incomplete type is used as a generic actual.
18515 (Find_Actual_Type): Extend routine to handle a component type in a child
18516 unit that is imported from a formal package in a parent.
18517 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18518 agree on constrainedness, rather than checking against ultimate ancestor
18519 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18520 generic body, for navigation purposes.

18523 Thomas Quinot <quinot@adacore.com>
18525 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18527 (New_Stream_Subprogram): When processing an attribute definition clause
18528 for a stream-oriented subprogram, record an entity node occurring at
18529 the point of clause to use for checking the visibility of the clause,
18530 as defined by 8.3(23) as amended by AI-195.
18531 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18532 New_Stream_Function and New_Stream_Procedure.
18533 (New_Stream_Function, New_Stream_Procedure): Removed.
18534 (Analyze_Attribute_Definition_Clause, case Address): Check new
18535 Alignment_Check check

18538 Javier Miranda <miranda@adacore.com>
18539 Robert Dewar <dewar@adacore.com>
18541 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18542 generate the same errors compiling under -gnatc.
18543 (Try_Object_Operation): If no candidate interpretation succeeds, but
18544 there is at least one primitive operation with the right name, report
18545 error in call rather than on a malformed selected component.
18546 (Analyze_Selected_Component): If the prefix is an incomplete type from
18547 a limited view, and the full view is available, use the full view to
18548 determine whether this is a prefixed call to a primitive operation.
18549 (Operator_Check): Verify that a candidate interpretation is a binary
18550 operation before checking the type of its second formal.
18551 (Analyze_Call): Add additional warnings for function call contexts not
18553 (Analyze_Allocator): Move the check for "initialization not allowed for
18554 limited types" after analyzing the expression. This is necessary,
18555 because OK_For_Limited_Init looks at the structure of the expression.
18556 Before analysis, we don't necessarily know what sort of expression it
18557 is. For example, we don't know whether F(X) is a function call or an
18558 indexed component; the former is legal in Ada 2005; the latter is not.
18559 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18560 were missing. We also didn't handle qualified expressions. Now also
18561 allow function calls. Use new common routine OK_For_Limited_Init.
18562 (Analyze_Type_Conversion): Do not perform some legality checks in an
18563 instance, because the error message will be redundant or spurious.
18564 (Analyze_Overloaded_Selected_Component): Do not do style check when
18565 setting an entity, since we do not know it is the right entity yet.
18566 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18567 (Analyze_Overloaded_Selected_Component): Same change
18568 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18569 since regular incomplete subtypes are transformed into corresponding
18570 subtypes of their full views.
18571 (Complete_Object_Operation): Treat name of transformed subprogram call
18572 as coming from source, for browsing purposes.
18573 (Try_Primitive_Operation): If formal is an access parameter, compare
18574 with base type of object to determine whether it is a primitive
18576 (Operator_Check): If no interpretation of the operator matches, check
18577 whether a use clause on any candidate might make the operation legal.
18578 (Try_Class_Wide_Operation): Check whether the first parameter is an
18579 access type whose designated type is class-wide.

18586 warn on infinite loops.
18587 Add \\ to some continuation messages
18588 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18589 (Process_Bounds): If the bounds are integer literals that result from
18590 constant-folding, and they carry a user-defined type, preserve that type
18591 rather than treating this as an integer range.
18592 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18593 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18594 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18595 left hand side of assignment.
18596 (Analyze_Assignment): Add suport to manage assigments to the attribute
18597 priority of a protected object.
18598 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18599 not just identifiers.
18600 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18601 or AND THEN for possible tracking.
18602 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18603 case of while loops so we can track values in the loop body.

18606 Hristian Kirtchev <kirtchev@adacore.com>
18607 Bob Duff <duff@adacore.com>
18609 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18610 procedure cannot be a protected operation (it is a basic_declaration,
18611 not a subprogram_declaration).
18612 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18613 Subp. Add logic for entry processing.
18614 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18615 Determine whether an entry or subprogram of a protected or task type
18616 override an inherited primitive of an implemented interface.
18617 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18618 Update the actual used in calls to Check_Overriding_Indicator.
18619 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18620 generate the proper reference to the parent unit, for cross-reference.
18621 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18623 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18624 (Add_Extra_Formal): Revise procedure to allow passing in associated
18625 entity, scope, and name suffix, and handle setting of the new
18626 Extra_Formals field.
18627 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18628 pass new parameters. Add support for adding the new extra access formal
18629 for functions whose calls are treated as build-in-place.
18630 (Analyze_A_Return_Statement): Correct casing in error message.
18631 Move Pop_Scope to after Analyze_Function_Return, because an extended
18632 return statement really is a full-fledged scope. Otherwise, visibility
18633 doesn't work right. Correct use of "\" for continuation messages.
18634 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18635 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18636 the node doesn't get properly marked as analyzed.
18637 (Analyze_Subprogram_Body): If subprogram is a function that returns
18638 an anonymous access type that denotes a task, build a Master Entity
18640 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18641 proper usage of null exclusion in a result definition.
18642 (Process_Formals): Code cleanup and new error message.
18643 (Process_Formals): Detect incorrect application of null exclusion to
18645 (Conforming_Types): Handle conformance between [sub]types and itypes
18646 generated for entities that have null exclusions applied to them.
18647 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18648 base type is an access subtype. This case arrises with null exclusions.
18649 (New_Overloaded_Entity): Do not remove the overriden entity from the
18650 homonym chain if it corresponds with an abstract interface primitive.
18651 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18652 call to the synthesized predicate Is_Incomplete_Type.
18653 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18655 (Analyze_Subprogram_Declaration): Check that abstract interface
18656 primitives are abstract or null.
18657 (Analyze_Subprogram_Specification): Remove previous check for abstract
18658 interfaces because it was not complete.
18659 (Has_Interface_Formals): Removed.

18662 Javier Miranda <miranda@adacore.com>
18664 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18665 of Analyze_Package_Body, to create Itype references for anonymous
18666 access types created in the package declaration, whose designated types
18667 may have only a limited view.
18668 (Analyze_Package_Specification): For the private part of a nested
18669 package, install private_with_clauses of enclosing compilation unit if
18670 we are in its visible part.
18671 (Declare_Inherited_Private_Subprograms): Complete barrier
18672 to ensure that the primitive operation has an alias to some parent
18673 primitive. This is now required because, after the changes done for the
18674 implementation of abstract interfaces, the contents of the list of
18675 primitives has entities whose alias attribute references entities of
18676 such list of primitives.
18677 (Analyze_Package_Specification): Simplify code that handles parent units
18678 of instances and formal packages.
18679 (Uninstall_Declarations): Check the convention consistency among
18680 primitive overriding operations of a tagged record type.

18689 expected and found set right)
18690 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18691 (Analyze_Generic_Renaming): Same fix
18692 (Use_One_Package): Do not take into account the internal entities of
18693 abstract interfaces during the analysis of entities that are marked
18694 as potentially use-visible.
18695 (Find_Type): Handle the case of an attribute reference for
18696 implementation defined attribute Stub_Type (simply let the analysis of
18697 the attribute reference rewrite it).
18698 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18699 type that appears in a Use_Type clause.
18700 (Analyze_Object_Renaming): Add support for renaming of the Priority
18702 (Find_Type): In Ada 2005, a task type can be used within its own body,
18703 when it appears in an access definition.
18704 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18705 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18706 in a formal object declaration or in a subtype declaration.
18707 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18708 (Check_Null_Exclusion): New local routine to
18709 Analyze_Subprogram_Renaming. Check whether the formals and return
18710 profile of a renamed subprogram have required null exclusions when
18711 their counterparts of the renaming already impose them.
18712 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18713 Determine whether an entity is inside a generic scope.
18714 (In_Open_Scope): First pass of documentation update.
18715 (Find_Expanded_Name): Add support for shadow entities associated with
18716 limited withed packages. This is required to handle nested packages.
18717 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18718 that makes a renaming of a limited withed package illegal.

18725 (Analyze_Task_Definition): Ditto.
18726 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18727 (Check_Overriding_Indicator): To find overridden interface operation,
18728 examine only homonyms that have an explicit subprogram declaration, not
18729 inherited operations created by an unrelated type derivation.
18730 (Check_Overriding_Indicator): When checking for the presence of "null"
18731 in a procedure, ensure that the queried node is a procedure
18733 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18734 type when the formal is an access to variable.
18735 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18736 (Analyze_Task_Type): Same addition

18745 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18746 inherited from an interface ancestor by another interface in the
18747 context of an instance as 'late'.

18749 of a call to a function that dispatches on access result.
18750 (Check_Dispatching_Operation): In case of late overriding of a primitive
18751 that covers abstract interface subprograms we register it in all the
18752 secondary dispatch tables associated with abstract interfaces.
18753 (Check_Dispatching_Call): Add check that a dispatching call is not made
18754 to a function with a controlling result of a limited type. This is a
18755 current implementation restriction.
18756 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18757 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18758 argument is an interface type that is a generic formal.
18759 (Is_Interface_Subprogram): Removed.
18760 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18761 operation, check the formals to handle the case in which it is
18762 associated with an abstract interface type.

18782 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18783 subprogram type to provide better diagnostics in case of ambiguity.
18784 (Covers): Handle coverage of formal and actual anonymous access types in
18785 the context of generic instantiation.
18786 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18787 abstract interface types; this is required to handle concurrent types
18788 with discriminants and abstract interface types.
18789 (Covers): Include type coverage of both regular incomplete subtypes and
18790 incomplete subtypes of incomplete type visibles through a limited with

19579 evaluate the conversion at run-time.
19580 (Resolve_Equality_Op): Do not apply previous

20256 were not always properly handled previously.
20257 Since we are changing the tree format anyway, also get rid of the
20258 junk obsolete Immediate_Errors flag.
20259 (Tree_Read): Change the way of reading Tree_Version_String - now we
20260 read the version string from the tree even if its length is not the
20261 same as the length of the version string computed from Gnatvsn.
20262 (Search_Directory_Present): New Boolean flag for the compiler.
20263 Define Tree_Version_String as a dynamic string.
20264 (Default_Stack_Size): new variable, used to handle switch -d.
20267 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20268 only for main unit.
20269 Add pragma Ada_2005 (synonym for Ada_05)
20270 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20271 were not always properly handled previously.
20273 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20274 explicit Ada_95 to Ada_2005.
20276 2006-02-13 Javier Miranda <miranda@adacore.com>
20277 Robert Dewar <dewar@adacore.com>
20278 Ed Schonberg <schonberg@adacore.com>
20280 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20281 against errors in the source program: a private types for which the
20282 corresponding full type declaration is missing and pragma CPP_Virtual
20284 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20285 (Is_Known_Null): New flag
20286 (Has_Pragma_Pure): New flag
20287 (No_Return): Present in all entities, set only for procedures
20288 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20289 explicitly declared limited.
20290 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20291 entities. Only used for component marked Is_Tag. If present it stores
20292 the Offset_To_Top function used to provide this value in tagged types
20293 whose ancestor has discriminants.
20295 * exp_ch2.adb: Update status of new Is_Known_Null flag
20297 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20299 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20300 the categorization sense if Is_Pure was set by pragma Pure_Function.
20302 2006-02-13 Quentin Ochem <ochem@adacore.com>
20303 Olivier Hainque <hainque@adacore.com>
20305 * bindusg.adb: Updated documentation for -d and -D switches.
20307 * raise.h (__gnat_set_globals): added new parameter for
20308 Default_Stack_Size.
20310 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20311 (__gnat_handle_vms_condition): Adjust context before raise.
20312 (__gnat_install_handler): Restore the global vector setup for GCC
20313 versions before 3.4, as the frame based circtuitry is not available
20315 (__gnat_set_globals): added a parameter default_stack_size
20316 (__gl_default_stack_size): new variable.
20318 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20320 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20321 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20322 does not exist in the Ada RM.
20323 (Compatible_Int_Bounds): Determine whether two integer range bounds
20324 are of equal length and have the same start and end values.
20325 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20326 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20327 aggregate when it is part of an object declaration.
20328 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20329 constrains discriminants of its parent, add explicitly the discriminant
20330 constraints of the ancestor by retrieving them from the
20331 stored_constraint of the parent.
20333 2006-02-13 Robert Dewar <dewar@adacore.com>
20335 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20336 attribute Mechanism_Code is applied to renamed subprogram, modify
20337 prefix to point to base subprogram.
20338 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20340 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20341 renamed subprograms so that the front-end must replace the prefix
20344 2006-02-13 Javier Miranda <miranda@adacore.com>
20345 Gary Dismukes <dismukes@adacore.com>
20347 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20348 availability of RE_Interface_Tag.
20349 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20350 (Freeze_Record_Type): Do not generate the tables associated with
20351 timed and conditional dispatching calls through synchronized
20352 interfaces if compiling under No_Dispatching_Calls restriction.
20353 When compiling for Ada 2005, for a nonabstract
20354 type with a null extension, call Make_Controlling_Function_Wrappers
20355 and insert the wrapper function declarations and bodies (the latter
20356 being appended as freeze actions).
20357 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20358 predefined primitives associated with timed and conditional
20359 dispatching calls through synchronized interfaces if we are
20360 compiling under No_Dispatching_Calls.
20361 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20362 service is available before generating a call.
20363 (Make_Controlling_Function_Wrappers): New procedure.
20364 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20365 access-to-limited-interfaces because they can be used to reference
20366 tasks that implement such limited interface.
20367 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20368 procedure spec and body of the Offset_To_Top function that is generated
20369 when the parent of a type with discriminants has secondary dispatch
20371 (Init_Secondary_Tags): Handle the case in which the parent of the type
20372 containing secondary dispatch tables has discriminants to generate the
20373 correct arguments to call Set_Offset_To_Top.
20374 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20376 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20377 Add Wide_[Wide_]Expanded_Name.
20378 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20379 the same functionality of Get_Prim_Op_Address but applied to predefined
20380 primitive operations because the pointers to the predefined primitives
20381 are now saved in a separate table.
20382 (Parent_Size): Modified to get access to the separate table of primitive
20383 operations or the parent type.
20384 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20385 functionality of Set_Prim_Op_Address but applied to predefined primitive
20387 (Set_Signature): New subprogram used to store the signature of a DT.
20388 (Displace): If the Offset_To_Top value is not static then call the
20389 function generated by the expander to get such value; otherwise use
20390 the value stored in the table of interfaces.
20391 (Offset_To_Top): The type of the actual has been changed to Address to
20392 give the correct support to tagged types with discriminants. In this
20393 case this value is stored just immediately after the tag field.
20394 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20395 offset_to_top value is static and hence pass this value to the run-time
20396 to store it in the table of interfaces, or else if this value is dynamic
20397 and then pass to the run-time the address of a function that is
20398 generated by the expander to provide this value for each object of the
20401 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20402 (Default_Prim_Op_Count): New entity
20403 (Get_Predefined_Prim_Op_Address): New entity
20404 (Set_Predefined_Prim_Op_Address): New entity
20405 (RE_Set_Signature): New entity
20407 2006-02-13 Thomas Quinot <quinot@adacore.com>
20408 Ed Schonberg <schonberg@adacore.com>
20410 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20411 Make_Adjust_Call done for a newly-allocated object.
20413 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20414 in a subprogram are wrapped in a cleanup block, indicate that the
20415 subprogram contains an inner block with an exception handler.
20416 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20417 Adjust call is for a newly-allocated object. In that case we must not
20418 assume that the finalization list chain pointers are correct (since they
20419 come from a bit-for-bit copy of the original object's pointers) so if
20420 the attach level would otherwise be zero (no change), we set it to 4
20421 instead to cause the pointers to be reset to null.
20423 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20424 reset chain pointers to null.
20426 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20428 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20429 string, and the context requires a loop for the assignment (e.g.
20430 because the left-hand side is packed), generate a unique name for the
20431 temporary that holds the string, to prevent spurious name clashes.
20433 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20434 Javier Miranda <miranda@adacore.com>
20435 Robert Dewar <dewar@adacore.com>
20436 Gary Dismukes <dismukes@adacore.com>
20438 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20439 return unconstrained arrays.
20441 (Expand_Call): An indirect call through an access parameter of a
20442 protected operation is not a protected call.
20443 Add circuit to raise CE in Ada 2005 mode following call
20444 to Raise_Exception.
20445 (Register_DT_Entry): Do nothing if
20446 the run-time does not give support to abstract interfaces.
20447 (Freeze_Subprogram): In case of dispatching operations, do not generate
20448 code to register the operation in the dispatch table if the source
20449 is compiled with No_Dispatching_Calls.
20450 (Register_Predefined_DT_Entry): Generate code that calls the new
20451 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20452 Set_Prim_Op_Address.
20454 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20455 on array assignments if the right-hand side is a function call that has
20456 been inlined. Check is performed on the assignment in the block.
20457 (Process_Bounds): If bounds and range are overloaded, apply preference
20458 rule for root operations to disambiguate, and diagnose true ambiguity.
20459 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20460 a tag-indeterminate right-hand side even when Expander_Active is True.
20461 Needed to ensure that dispatching calls to T'Input are allowed and
20462 get the tag of the target class-wide object.
20464 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20465 an inherited primitive operation that already overrides several
20466 abstract interface primitives. For transitivity, the new entity must
20467 also override all the abstract interface primitives covered by the
20468 inherited overriden primitive.
20469 Emit warning if new entity differs from homograph in same scope only in
20470 that one has an access parameter and the other one has a parameter of
20471 a general access type with the same designated type, at the same
20472 position in the signature.
20473 (Make_Inequality_Operator): Use source locations of parameters and
20474 subtype marks from corresponding equality operator when creating the
20475 tree structure for the implicit declaration of "/=". This does not
20476 change anything in behaviour except that the decoration of the
20477 components of the subtree created for "/=" allows ASIS to get the
20478 string images of the corresponding identifiers.
20479 (Analyze_Return_Statement): Remove '!' in warning message.
20480 (Check_Statement_Sequence): Likewise.
20481 (Analyze_Subprogram_Body): For an access parameter whose designated type
20482 is an incomplete type imported through a limited_with clause, use the
20483 type of the corresponding formal in the body.
20484 (Check_Returns): Implicit return in No_Return procedure now raises
20485 Program_Error with a compile time warning, instead of beging illegal.
20486 (Has_Single_Return): Function returning unconstrained type cannot be
20487 inlined if expression in unique return statement is not an identifier.
20488 (Build_Body_To_Inline): It is possible to inline a function call that
20489 returns an unconstrained type if all return statements in the function
20490 return the same local variable. Subsidiary procedure Has_Single_Return
20491 verifies that the body conforms to this restriction.
20493 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20494 same type, and one of them is of an anonymous access type, convert
20495 the other operand to it, so that this is a valid binary operation for
20497 (Resolve_Type_Conversion): Handle subtypes of protected types and
20498 task types when accessing to the corresponding record type.
20499 (Resolve_Allocator): Add '\' in 2-line warning message.
20500 Remove '!' in warning message.
20501 (Resolve_Call): Add '\' in 2-line warning message.
20502 (Valid_Conversion): Likewise.
20503 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20504 resulting type may be an access type with an implicit dereference.
20505 Obtain the proper component from the designated type.
20506 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20507 given by an expanded name with prefix Standard, when the operands are
20508 of an anonymous access type.
20509 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20510 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20511 prefix of the expression is not of an incomplete type. Allows full
20512 diagnoses of all semantic errors.
20513 (Resolve_Actuals): If the actual is an allocator whose directly
20514 designated type is a class-wide interface we build an anonymous
20515 access type to use it as the type of the allocator. Later, when
20516 the subprogram call is expanded, if the interface has a secondary
20517 dispatch table the expander will add a type conversion to force
20518 the displacement of the pointer.
20519 (Resolve_Call): If a function that returns an unconstrained type is
20520 marked Inlined_Always and inlined, the call will be inlined and does
20521 not require the creation of a transient scope.
20522 (Check_Direct_Boolean_Op): Removed
20523 (Resolve_Comparison_Op): Remove call to above
20524 (Resolve_Equality_Op): Remove call to above
20525 (Resolve_Logical_Op): Inline above, since this is only call.
20526 (Valid_Conversion): Handle properly conversions between arrays of
20527 convertible anonymous access types.
20530 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20531 the literal in an unchecked conversion, because GCC 4.x needs a static
20532 value for a string bound.
20534 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20535 Hristian Kirtchev <kirtchev@adacore.com>
20537 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20538 components of the corresponding record, take into account component
20539 definitions that are access definitions.
20540 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20541 procedure is not considered a dispatching call and will be expanded
20544 2006-02-13 Javier Miranda <miranda@adacore.com>
20546 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20547 controlling argument of the dispatching call is an abstract interface
20548 class-wide type then we use it directly.
20549 Check No_Dispatching_Calls restriction.
20550 (Default_Prim_Op_Position): Remove the code that looks for the last
20551 entity in the list of aliased subprograms. This code was wrong in
20553 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20554 when the source is compiled with the No_Dispatching_Calls restriction.
20555 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20556 if we are compiling with restriction No_Dispatching_Calls.
20557 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20558 subprograms if we are compiling under No_Dispatching_Calls restriction.
20559 (Make_DT): Generate a dispatch table with a single dummy entry if
20560 we are compiling with the No_Dispatching_Calls restriction. In
20561 addition, in this case we don't generate code that calls to the
20562 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20563 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20564 of this subprogram if compiling with the No_Dispatching_Calls
20566 (Expand_Type_Conversion): Instead of using the actual parameter,
20567 the argument passed as parameter to the conversion function was
20568 erroneously referenced by the expander.
20569 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20570 Set_Predefined_Primitive_Op_Address and Set_Signature.
20571 (Expand_Dispatching_Call): Generate call to
20572 Get_Predefined_Prim_Op_Address for predefined primitives.
20573 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20574 predefined primitives.
20575 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20576 primitives we reserve one dummy entry to ensure that the tag does not
20577 point to some memory that is associated with some other object. In
20578 addition, remove all the old code that generated the assignments
20579 associated with the signature of the dispatch table and replace them
20580 by a call to the new subprogram Set_Signature.
20581 (Set_All_DT_Position): Change the algorithm because now we have a
20582 separate dispatch table associated with predefined primitive operations.
20583 (Expand_Interface_Conversion): In case of non-static offset_to_top
20584 add explicit dereference to get access to the object after the call
20585 to displace the pointer to the object.
20586 (Expand_Interface_Thunk): Modify the generation of the actual used
20587 in the calls to the run-time function Offset_To_Top to fulfil its
20589 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20591 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20593 * exp_dist.adb (Copy_Specification): For access parameters, copy
20594 Null_Exclusion flag, which will have been set for stream subprograms
20597 2006-02-13 Pascal Obry <obry@adacore.com>
20599 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20600 previous implementation was using the C runtime spawnve routine but
20601 the corresponding wait was using directly the Win32 API. This was
20602 causing some times a lock when waiting for an event using
20603 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20604 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20605 API fixes this problem.
20607 2006-02-13 Robert Dewar <dewar@adacore.com>
20609 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20612 2006-02-13 Thomas Quinot <quinot@adacore.com>

20616 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20617 array reference that is an explicit dereference, mark the converted
20618 (packed) array reference as analyzed to prevent a forthcoming
20619 reanalysis from resetting its type to the original (non-packed) array
20622 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20623 Javier Miranda <miranda@adacore.com>
20624 Eric Botcazou <ebotcazou@adacore.com>
20626 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20627 Is_Predefined_Primitive_Operation): When
20628 searching for the predefined equality operator, verify that operands
20629 have the same type.
20630 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20631 for the last entity in the list of aliased subprograms. This code
20632 was wrong in case of renamings.
20633 (Set_Renamed_Subprogram): New procedure
20634 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20635 Exp_Type constant computed when entering this subprogram.
20636 (Known_Null): New function
20637 (OK_To_Do_Constant_Replacement): New function
20638 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20639 (Side_Effect_Free): An attribute reference 'Input is not free of
20640 side effect, unlike other attributes that are functions. (from code
20642 (Remove_Side_Effects): Expressions that involve packed arrays or records
20643 are copied at the point of reference, and therefore must be marked as
20644 renamings of objects.
20645 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20646 not a dispatching operation.
20649 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20650 elementary types in all cases.
20652 2006-02-13 Javier Miranda <miranda@adacore.com>
20654 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20655 task types when accessing to the corresponding record type.
20656 Remove '!' in warning message.
20658 2006-02-13 Olivier Hainque <hainque@adacore.com>
20660 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20661 to avoid useless and space inefficient overalignments on targets where
20662 Max_Alignment is larger than 16.
20664 2006-02-13 Pascal Obry <obry@adacore.com>
20666 * g-catiio.adb (Sec_Number): New type used to compute the number of
20667 seconds since 1-1-1970.
20668 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20669 negative numbers (years, months...) it is better to have a Natural here.
20671 (Image) [Number]: Change parameter from Long_Integer to Number.
20672 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20673 overflow for dates past year 2038.
20675 2006-02-13 Matthew Heaney <heaney@adacore.com>
20677 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20680 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20682 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20684 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20685 finalization can occur normally.
20687 2006-02-13 Vincent Celier <celier@adacore.com>
20689 * gnatcmd.adb (Rules_Switches): New table
20690 (Add_To_Rules_Switches): New procedure
20691 (GNATCmd): For command CHECK, put all options following "-rules" in the
20692 Rules_Switches table. Append these -rules switches after the -cargs
20695 2006-02-13 Robert Dewar <dewar@adacore.com>
20697 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20698 These two cases were generating incorrect output, and if this unit
20699 was built with checks on, generated a discriminant mismatch constraint
20702 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20703 Robert Dewar <dewar@adacore.com>
20705 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20706 view is an array type, indicate the component type as well, for
20707 navigation purposes.
20708 (Generate_Reference): Don't consider array ref on LHS to be a case
20709 of violating pragma Unreferenced.
20710 Do not give Ada 2005 warning except on real reference.

20714 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20715 main source, add switch -mdebug-main=_ada_ so that the executable can
20716 be debugged by the standard VMS debugger.
20717 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20718 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20719 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20720 of the last source, as the binding and linking phases are never
20722 Set all executable obsolete when rebuilding a library.
20724 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20727 2006-02-13 Javier Miranda <miranda@adacore.com>
20730 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20731 code to improve the error message reported when the program has
20732 declarations of abstract interface types and it is not compiled with
20733 the -gnat05 switch.
20734 (P_Access_Definition): Reorganize the code to improve the error
20735 message reported when the new Ada 2005 syntax for anonymous
20736 access types is used and the program is not compiled with the

20759 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20760 unknown, use the location of the project to report the error.
20761 (When_No_Sources): New global variable
20762 (Report_No_Ada_Sources): New procedure
20763 (Check): New parameter When_No_Sources. Set value of global variable

20766 (Get_Sources_From_File): Ditto
20767 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20770 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20771 Call Prj.Proc.Process with parameter When_No_Sources.
20773 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20774 Call Recursive_Check with parameter When_No_Sources.
20775 (Recursive_Check): New parameter When_No_Sources. Call itself and
20776 Prj.Nmsc.Check with parameter When_No_Sources.
20777 (Process): New parameter When_No_Sources. Call Check with parameter
20779 (Copy_Package_Declarations): New procedure to copy renamed parameters

20789 When removing nodes (attributes Source_Dirs, Source_Files,
20790 Source_List_File and package Naming), save the comments and attach the
20791 saved comments to the newly created nodes.
20792 Do not add a with clause for the naming package if one already exists.

20800 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20801 aliased entities to look for the overriden abstract interface
20803 (Is_Interface_Subprogram): Complete documentation.
20804 (Check_Dispatching_Operation): Do not generate code to register the
20805 operation in the dispatch table if the source is compiled with
20806 restriction No_Dispatching_Calls.

20808 No_Return procedure with procedure that is not No_Return
20809 (Check_Dispatching_Call): Suppress the check for an abstract operation
20810 when the original node of an actual is a tag-indeterminate attribute
20811 call, since the attribute, which must be 'Input, can never be abstract.
20812 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20813 call to the Input attribute (even when rewritten).
20814 (Propagate_Tag): Augment comment to indicate the possibility of a call
20815 to an Input attribute.
20817 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20818 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

20827 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20829 2006-02-13 Javier Miranda <miranda@adacore.com>
20831 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20832 handles default-initialized components to keep separate the management
20833 of this feature but also avoid the unrequired resolution and
20834 expansion of components that do not have partially initialized
20836 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20837 (Check_Bounds): Likewise.
20838 (Check_Length): Likewise.
20840 2006-02-13 Javier Miranda <miranda@adacore.com>
20841 Ed Schonberg <schonberg@adacore.com>
20843 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20844 abstract interface type call analyze_and_resolve to expand the type
20845 conversion into the corresponding displacement of the
20846 reference to the base of the object.
20847 (Eval_Attribute, case Width): For systems where IEEE extended precision
20848 is supported, the maximum exponent occupies 4 decimal digits.
20849 (Accessibility_Message): Add '\' in 2-line warning message.
20850 (Resolve_Attribute): Likewise.
20851 (case Attribute_Access): Significantly revise checks
20852 for illegal access-to-subprogram Access attributes to properly enforce
20853 the rules of 3.10.2(32/2).
20854 Diagnose use of current instance with an illegal attribute.
20856 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20858 (Enclosing_Generic_Unit): New function to return a node's innermost
20859 enclosing generic declaration node.
20860 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20861 (Type_Access_Level): The accessibility level of anonymous acccess types
20862 associated with discriminants is that of the current instance of the
20863 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20864 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20865 (Kill_Current_Values_For_Entity): New function
20866 (Enter_Name): Change formal type to Entity_Id
20868 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20869 Ed Schonberg <schonberg@adacore.com>
20870 Gary Dismukes <dismukes@adacore.com>
20872 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20873 Analyze_Compilation_Unit.
20874 Detect and warn on redundant with clauses detected in a package spec
20875 and/or body when -gnatwr is used.
20876 (Analyze_Context): Analyze config pragmas before other items
20877 (Install_Context_Items): Don't analyze config pragmas here
20878 (Install_Limited_Withed_Unit): Set limited entity of package in
20879 with_clause so that cross-reference information or warning messages on
20880 unused packages can be properly generated
20881 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20882 has Error_Posted set. Prevent infinite loops in illegal programs.
20883 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20884 to the point of the error test requiring the current unit to be private.
20885 This ensures that private with clauses are not exempted from the basic
20886 checking for being a descendant of the same library unit parent as a
20887 withed private descendant unit.
20888 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20889 handle private with clauses properly, as well as to account for cases
20890 where the withed unit is a public descendant of a private ancestor
20891 (in which case the current unit must be a descendant of the private
20892 ancestor's parent). The spec comments were updated accordingly. Also,
20893 the old error message in this subprogram was replaced with error
20894 messages that mirror the errors tested and reported by
20895 Check_Private_Child_Unit.
20896 Parameter and variable names improved for readability.
20897 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20898 private as the precondition for calling
20899 Check_Private_Limited_Withed_Unit since that subprogram has been
20900 revised to test public units as well as private units.

20905 Javier Miranda <miranda@adacore.com>
20907 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20908 that Scope_Stack.First = 1.
20909 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20910 were not always properly handled previously.
20911 (Formal_Entity): Complete rewrite, to handle properly some complex case
20912 with multiple levels of parametrization by formal packages.
20913 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20914 to the corresponding derived type declaration for proper semantics.
20916 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20917 (Check_Component): Enforce restriction on components of
20918 unchecked_unions: a component in a variant cannot contain tasks or
20920 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20922 Add pragma Ada_2005 (synonym for Ada_05)
20923 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20924 were not always properly handled previously.
20925 Document that pragma Propagate_Exceptions has no effect
20926 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20927 (Set_Convention_From_Pragma): Check that if a convention is
20928 specified for a dispatching operation, then it must be
20929 consistent with the existing convention for the operation.
20930 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20931 longer required to specify an vtable-ptr component in the record. For
20932 compatibility reasons we leave the support for the previous definition.
20933 (Analyze_Pragma, case No_Return): Allow multiple arguments
20935 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20936 non-overrideen inherited operation with a controlling result as
20937 illegal only its implicit declaration comes from the derived type
20938 declaration of its result's type.
20939 (Check_Possible_Deferred_Completion): Relocate the object definition
20940 node of the subtype indication of a deferred constant completion rather
20941 than directly analyzing it. The analysis of the generated subtype will
20942 correctly decorate the GNAT tree.
20943 (Record_Type_Declaration): Check whether this is a declaration for a
20944 limited derived record before analyzing components.
20945 (Analyze_Component_Declaration): Diagnose record types not explicitly
20946 declared limited when a component has a limited type.
20947 (Build_Derived_Record_Type): Code reorganization to check if some of
20948 the inherited subprograms of a tagged type cover interface primitives.
20949 This check was missing in case of a full-type associated with a private
20951 (Constant_Redeclaration): Check that the subtypes of the partial and the
20952 full view of a constrained deferred constant statically match.
20953 (Mentions_T): A reference to the current type in an anonymous access
20954 component declaration must be an entity name.
20955 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20956 class_wide type to refer to full type, not to the incomplete one.
20957 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20958 available. Required to give support to the certified run-time.
20959 (Analyze_Component_Declaration): In case of anonymous access components
20960 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20961 (Process_Discriminants): For an access discriminant, use the
20962 discriminant specification as the associated_node_for_itype, to
20963 simplify accessibility checks.
20965 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20966 Javier Miranda <miranda@adacore.com>
20968 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20969 abstract interpretations on an operator, remove interpretations that
20970 yield Address or a type derived from it, if one of the operands is an
20972 (Try_Object_Operation.Try_Primitive_Operation,
20973 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20974 location when creating the new reference to a primitive or class-wide
20975 operation as a part of rewriting a subprogram call.
20976 (Try_Primitive_Operations): If context requires a function, collect all
20977 interpretations after the first match, because there may be primitive
20978 operations of the same type with the same profile and different return
20979 types. From code reading.
20980 (Try_Primitive_Operation): Use the node kind to choose the proper
20981 operation when a function and a procedure have the same parameter
20983 (Complete_Object_Operation): If formal is an access parameter and prefix
20984 is an object, rewrite as an Access reference, to match signature of
20985 primitive operation.
20986 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20987 by an expanded name with prefix Standard, when the operands are of an
20988 anonymous access type.
20989 (Remove_Abstract_Operations): If the operation is abstract because it is
20990 inherited by a user-defined type derived from Address, remove it as
20991 well from the set of candidate interpretations of an overloaded node.
20992 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20995 2006-02-13 Bob Duff <duff@adacore.com>
20997 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20998 redundant use clauses.
20999 In particular, if the scope of two use clauses overlaps, but one is not
21000 entirely included in the other, we should not warn. This can happen
21001 with nested packages.
21002 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21003 reported errors. The bug was reported when the compiler was built
21004 with assertions enabled.
21005 (Find_Type): If the node is a 'Class reference and the prefix is a
21006 synchronized type without a corresponding record, return the type
21009 2006-02-13 Javier Miranda <miranda@adacore.com>
21011 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21012 if this is the full-declaration associated with a private declaration
21013 that implement interfaces, then the private type declaration must be
21015 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21016 as aliased. The use of the 'access attribute is not available for such
21017 object (for this purpose the object should be explicitly marked as
21018 aliased, but being an anonymous type this is not possible).
21020 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21021 Robert Dewar <dewar@adacore.com>
21023 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21024 compilation unit is an elaboration scope.
21025 (Add_Task_Proc): Add '\' in 2-line warning message.
21026 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21028 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21029 Javier Miranda <miranda@adacore.com>
21031 * sem_type.adb (Write_Overloads): Improve display of candidate
21033 (Add_One_Interp): Do not add to the list of interpretations aliased
21034 entities corresponding with an abstract interface type that is an
21035 immediate ancestor of a tagged type; otherwise we have a dummy
21036 conflict between this entity and the aliased entity.
21037 (Disambiguate): The predefined equality on universal_access is not
21038 usable if there is a user-defined equality with the proper signature,
21039 declared in the same declarative part as the designated type.
21040 (Find_Unique_Type): The universal_access equality operator defined under
21041 AI-230 does not cover pool specific access types.
21042 (Covers): If one of the types is a generic actual subtype, check whether
21043 it matches the partial view of the other type.
21045 2006-02-13 Thomas Quinot <quinot@adacore.com>
21047 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21048 line. This is necessary to allow In_Extended_Main_Unit to provide
21049 correct results for itypes while writing out expanded source.
21050 (Close_File): No need to update the source_index_table here since it's
21051 now done for each line.
21053 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21054 Robert Dewar <dewar@adacore.com>
21056 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21057 preserve the source unit where the itype is declared, and prevent a
21059 (Note_Implicit_Run_Time_Call): New procedure
21060 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21063 * sprint.ads: Document use of $ for implicit run time routine call
21065 2006-02-13 Quentin Ochem <ochem@adacore.com>
21067 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21070 2006-02-13 Bob Duff <duff@adacore.com>
21072 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21073 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21074 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21075 raise Constraint_Error.
21077 * s-vallli.adb (Scan_Long_Long_Integer): Call
21078 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21079 do not scan leading blanks and sign twice.
21080 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21081 raise Constraint_Error.
21083 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21084 Scan_Long_Long_Unsigned): Split out most of the processing from
21085 Scan_Long_Long_Unsigned out into
21086 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21087 This prevents scanning leading blanks and sign twice.
21088 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21091 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21092 out most of the processing from Scan_Unsigned out into
21093 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21094 This prevents scanning leading blanks and sign twice.
21096 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21097 use with Modular'Value attribute.
21098 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21296 * a-taster.ads, a-taster.adb: New files.
21298 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21299 link to the version that does nothing. This way the task termination
21300 routine is not executed twice for the environment task when finishing
21301 because of an unhandled exception.
21303 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21304 handler because of an unhandled exception.
21306 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21312 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21313 non-tasking version of the soft link for task termination. We do
21314 nothing since if we are using the non-tasking version it
21315 means that the task termination functionality is not used.
21316 (Null_Finalize_Global_List): Add this null version for the procedure
21317 in charge of finalizing the global list for controlled objects.
21318 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21319 instead for handling run-time termination in a more flexible way.
21320 (Adafinal_NT): This new procedure will take care of finalizing the
21321 global list for controlled objects if needed, but no tasking
21324 * s-tarest.adb (Task_Lock): Do not try to lock again the
21325 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21326 some run-time operations.
21327 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21328 until all nested locks have been released.
21329 (Task_Wrapper): Call the fall-back task termination handler. It
21330 applies to all tasks but the environment task.
21331 (Finalize_Global_Tasks): Add the call for the task termination
21332 procedure for the environment task.
21333 (Task_Wrapper): suppress warnings around declaration of
21334 Secondary_Stack_Address.

21337 moved to the Common_ATCB record.
21338 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21339 Common_ATCB record.
21340 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21341 Common_ATCB record.
21343 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21344 Fall_Back_Handler, and Specific_Handler.
21346 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21347 defined in Ada.Task_Termination, to avoid circular dependencies.
21348 (Termination_Handler): Redefine this type here, alredy defined in
21349 Ada.Task_Termination, for avoiding circular dependencies.
21350 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21351 for storing task termination handlers. In addition,
21352 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21353 Common_ATCB because it is used by both the regular and the restricted
21355 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21356 Common_ATCB because it is used by both the regular and the restricted
21358 (Common_ATCB): Added a dynamic task analyzer field.

21363 tasks but the environment task.
21364 (Finalize_Global_Tasks): Call the task termination procedure for the
21365 environment task. The call to Finalize_Global_List is now performed
21366 using the soft links mechanism.
21367 (Task_Wrapper): added dynamic stack analysis.
21369 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21370 potentially blocking operations has been moved from
21371 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21372 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21373 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21374 this run-time check.
21376 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21377 of task termination procedure.
21378 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21420 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21421 to the specification because the frontend generates code that uses this
21423 (Set_Interface_Table): Add missing assertion.
21424 Update documentation describing the run-time structure.
21425 (Displace): New subprogram that displaces the pointer to the object
21426 to reference one of its secondary dispatch tables.
21427 (IW_Membership): Modified to use the new table of interfaces.
21428 (Inherit_TSD): Modified to use the new table of interfaces.
21429 (Register_Interface_Tag): Use the additional formal to fill the
21430 contents of the new table of interfaces.
21431 (Set_Interface_Table): New subprogram that stores in the TSD the

21446 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21447 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21448 record component containing the tag of the secondary dispatch table we
21449 have to use the Offset_To_Top run-time function to get this information;
21450 otherwise if the pointer to the base of the object has been displace
21451 we get a wrong value if we use the 'position attribute.
21453 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21454 all the calls to Expand_Interface_Thunk.
21455 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21458 ensure that the interfaces implemented by the ancestors are placed
21459 at the header of the generated list.
21460 (Expand_Interface_Conversion): Handle the case in which the displacement
21461 associated with the interface conversion is not statically known. In
21462 this case we generate a call to the new run-time subprogram Displace.

21464 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21465 Get_Tagged_Kind and Set_Tagged_Kind.

21473 secondary dispatch table respectively of a tagged type.
21475 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
21476 (Expand_Interface_Conversion): New subprogram to indicate if the
21477 displacement of the type conversion is statically known.

21487 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21488 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21489 RE_TK_Tagged, RE_TK_Task.
21491 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21492 Init_Secondary_Tags_Internal to allow its use with interface types and
21493 also to generate the code for the new additional actual required
21494 by Set_Offset_To_Top.
21495 (Build_Init_Statements): In case of components associated with abstract
21496 interface types there is no need to generate a call to its IP.
21497 (Freeze_Record_Type): Generate Select Specific Data tables only for
21499 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21500 the bodies and specifications of the predefined primitive operations
21501 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21502 for concurrent types.

21506 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21507 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21508 properly protected objects and attach handler in the case of the
21509 restricted profile.
21510 Move embeded package Select_Expansion_Utilities into a separate external

21522 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21523 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21524 about the use and expansion of SAVE_EXPRs in the various possible
21525 renaming handling cases.
21526 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21527 abusing DECL_FCONTEXT.

21620 the iterator is quitting iteration on parent directory.
21622 2005-12-09 Javier Miranda <miranda@adacore.com>
21624 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21625 and the assignment to a class-wide object, before the assignment we
21626 generate a run-time check to ensure that the tag of the Target is
21627 covered by the tag of the source.

21692 copied component does not have a known static Esize, then reset
21693 the size and positional fields of the new component.
21694 (Analyze_Component_Declaration): A limited component is
21695 legal within a protected type that implements an interface.
21696 (Collect_Interfaces): Do not add to the list the interfaces that
21697 are implemented by the ancestors.
21698 (Derived_Type_Declaration): If the parent of the full-view is an
21699 interface perform a transformation of the tree to ensure that it has
21700 the same parent than the partial-view. This simplifies the job of the
21701 expander in order to generate the correct object layout, and it is
21702 needed because the list of interfaces of the full-view can be given in
21704 (Process_Full_View): The parent of the full-view does not need to be
21705 a descendant of the parent of the partial view if both parents are
21707 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21708 "limited" the parent must be a limited type.

21720 lists of interfaces constitute a set equality. If not, the first
21721 differing interface is returned.
21722 (Process_Full_View): Improve the check for the "no hidden interface"
21723 rule as defined by AI-396.

21782 available user-specified stream attributes on limited parameters to
21783 also test the type directly rather than only its underlying type (for
21784 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21785 attributes are visible at the point of the subprogram declaration.
21786 For Ada 2005, the error message is modified to indicate that the
21787 type's stream attributes must be visible (again, only for -gnat05).

21819 types use the corresponding record type. This was not needed before
21820 the implementation of Ada 2005 synchronized types because
21821 concurrent types were never tagged types in Ada 95.

21949 * socket.c: Add extern int h_errno for rtems since networking header
21950 files are not available at this point in a tool bootstrap. Newlib

21972 can't handle that case.
21974 2005-11-17 Laurent Guerby <laurent@guerby.net>
21977 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22067 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22068 elementary types using the operator in standard. It is cleaner not to
22069 modify the programmers intent, especially in the case of floating-point.
22070 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22071 it did not matter because we always rewrote a/=b to not(a=b).
22072 (Expand_Allocator_Expression): For an allocator expression whose nominal
22073 subtype is an unconstrained packed type, convert the expression to its
22074 actual constrained subtype.
22075 Implement warning for <= or >= where < or > not possible
22076 Fix to Vax_Float tests (too early in many routines, causing premature
22077 Vax_Float expansions.

22083 of pragma Suppress (All_Checks)
22084 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22085 a string literal for precise control over warnings.
22086 Avoid raise of pragma in case of unrecognized pragma and just return

22091 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22092 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22094 Include -gnatwx as part of -gnatg (warn on redundant parens)
22095 Allow optional = after -gnatm
22096 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22097 longer sets Elaboration_Checks.
22098 Code to set warning mode moved to Sem_Warn
22099 so that it can be shared by pragma processing.
22101 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22113 * exp_vfpt.adb: Handle /= case
22114 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22226 we are not defining the type.
22227 <E_Record_Type>: Likewise.
22228 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22229 to get advantage of the new maybe_stabilize_reference interface, to
22230 ensure that what we reference is indeed stabilized instead of relying
22231 on assumptions on what the stabilizer does.
22232 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22233 type imported through a limited_with clause, use its non-limited view.
22234 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22236 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22237 of #if sections + explicit comparisons of convention identifiers.

22239 before early-returning for certain types when code generation is
22241 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22243 that we are not defining.
22244 (elaborate_expression_1): Do not create constants when creating
22245 variables needed by the debug info: the dwarf2 writer considers that
22246 CONST_DECLs is used only to represent enumeration constants, and emits
22248 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22249 object with an address clause into an indirect reference, drop the
22250 initializing expression.

22262 subtype to build an actual type with bounds template.
22263 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22264 is provided by the front-end, use that subtype to compute the size of
22265 the deallocated object.

22267 check for a potential violation of a No_Elaboration_Code restriction.

22272 maybe_stabilize, for common uses without restriction on lvalues and
22273 without need to check for the success indication.
22274 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22275 pass false instead of 0 as the FORCE argument which is a bool.
22276 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22277 attached to a renaming pointer has been properly stabilized, as no such
22278 object is attached otherwise.
22279 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22280 function uses the "target pointer" return mechanism.
22281 Reinstate conversion of the actual to the type of the formal
22282 parameter before any other specific treatment based on the passing
22283 mechanism. This turns out to be necessary in order for PLACEHOLDER
22284 substitution to work properly when the latter type is unconstrained.

22288 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22292 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22293 static output of record constructor if all the components are constant.
22294 (gnat_build_constructor): For a record type, sort the list of field
22295 initializers in increasing bit position order.
22296 Factor common code to build a storage type for an unconstrained object
22297 from a fat or thin pointer type and a constrained object type.
22298 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22299 types variants, and process special cases of VIEW_CONVERT expressions
22300 as their NOP_EXPR counterpart to ensure we get to the
22301 CORRESPONDING_VARs associated with CONST_DECls.
22302 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22303 on the right-hand side.
22305 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22310 extracting the object if converting to a type variant.
22311 (create_var_decl): When a variable has an initializer requiring code
22312 generation and we are at the top level, check for a potential violation
22313 of a No_Elaboration_Code restriction.
22314 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22315 SIZE and SIZE_UNIT which we need for later back-annotations.

22318 is an unchecked union.
22319 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22320 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22321 main variant, just replace the VIEW_CONVERT_EXPR.

22500 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22501 'Unrestricted_Access, if the designated type is an interface we
22502 add a type conversion to force the displacement of the pointer

22504 Use Universal_Real instead of Long_Long_Float when we need a high
22505 precision float type for the generated code (prevents gratuitous
22506 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22507 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22508 'Terminated for task interface class-wide objects. Generate a call to
22509 the predefined dispatching routine used to retrieve the _task_id from

22539 the return value into its actual subtype in order to help the backend
22540 to return the actual size instead of the maximum. This is another

22590 attribute of the N_Free_Statement.
22591 Generate itype for classwide designated object in both cases of
22592 user-specified storage pool: specific and class-wide, not only in the
22594 Raise CE when trying to set a not null access type object to null.

22871 In addition some minor reorganization of the code has been done to
22872 leave it more clear.
22873 (Analyze_Type_Declaration): If type has previous incomplete tagged
22874 partial view, inherit properly its primitive operations.

22926 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22927 not try to rewrite a renamed stream attribute, because the operations
22928 on the type may not have been generated.
22929 Handle properly a renaming_as_body generated for a stream operation
22930 whose default is abstract because the object type itself is abstract.
22931 (Find_Type): If the type is incomplete and appears as the prefix of a
22932 'Class reference, it is tagged, and its list of primitive operations
22933 must be initialized properly.
22934 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22935 private declaration of a parent unit, prior to compiling the private
22936 part of a child unit, find on the scope stack the proper parent entity
22937 on which to link the use clause.

22961 remove address operations.
22962 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22963 statement to inhibit warning.
22964 (Resolve_Unary_Op): Do not produce a warning when
22965 processing an expression of the form -(A mod B)
22966 Use Universal_Real instead of Long_Long_Float when we need a high

22969 (Resolve_Concatenation_Arg): Improve error message when argument is an
22970 ambiguous call to a function that returns an array.
22971 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23946 Hristian Kirtchev <kirtchev@adacore.com>
23947 Javier Miranda <miranda@adacore.com>
23949 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23950 from object notation, the original node is unanalyzed and carries no
23951 semantic information, so that accessiblity checks must be performed on
23952 the type of the actual itself.
23953 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23954 compatibility with Build_Protected_Sub_Specification.
23955 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23965 load comes from a Limited_With_Clause.
23967 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23968 whether a potential circularity is harmless, because it includes units
23969 loaded through a limited_with clause. Extends previous treatment which
23970 did not handle properly arbitrary combinations of limited and
23971 non-limited clauses.
23973 2005-09-01 Nicolas Setton <setton@adacore.com>
23975 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

23988 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
23989 fully qualified name, to distinguish instances with the same local name.

24003 (Close): Deallocate any existing filter for the concerned connection
24005 2005-09-01 Laurent Pautet <pautet@adacore.com>
24007 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24008 position set is provided, we compute one in order to reduce the maximum
24009 length of the keys. This computation first selects a character
24010 position between 1 and the minimum length of the keys in order to
24011 avoid reducing one of the keys to an empty string.
24012 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24013 does not converge. The initialization procedure now comes with a
24014 maximum number of iterations such that when exceeded, an exception is
24015 raised in Compute. The user can initialize this ratio to another value
24017 Reformating and updated headers.

24021 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24022 that given an entity T creates and returns an Itype that duplicates the
24023 contents of T. The returned Itype has the null-exclusion
24024 attribute set to True, and its Etype attribute references T
24025 to keep the association between the two entities.
24026 Update copyright notice
24028 * sem_aggr.adb (Check_Can_Never_Be_Null,
24029 Aggregate_Constraint_Checks, Resolve_Aggregate,
24030 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.

24062 and N_Function_Specification.
24064 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24065 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.

24120 * snames.h, snames.ads, snames.adb: Introduce entries in
24121 Preset_Names for Name_Disp_Asynchronous_Select,
24122 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24123 Name_Disp_Timed_Select.
24124 New pragma Debug_Policy
24126 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24128 Switch -gnata also sets Debug_Pragmas_Enabled
24130 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24131 handle an explicit -gnata when compiling predefined files.
24133 2005-09-01 Vincent Celier <celier@adacore.com>
24135 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24136 directories of projects that have no Ada sources.
24138 2005-09-01 Robert Dewar <dewar@adacore.com>
24140 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24141 (makes a difference for wide characters)
24143 * widechar.adb, widechar.ads:
24144 Add Wide_Char_Byte_Count feature to count chars vs bytes
24146 2005-09-01 Thomas Quinot <quinot@adacore.com>
24147 Ed Schonberg <schonberg@adacore.com>
24148 Robert Dewar <dewar@adacore.com>
24150 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24151 'Address attribute reference with an overloaded prefix, use the
24152 location of the prefix (not the location of the attribute reference) as
24153 the error location.
24154 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24155 a function renaming thereof, is a valid prefix for 'Size (where it is
24156 intepreted as a function call).
24157 (Statically_Denotes_Entity): New predicate to determine whether the
24158 prefix of an array attribute can be considered static.
24161 (Eval_Attr): Fix failure to evaluate Component_Size for
24162 unconstrained arrays (resulted in wrong value in packed case, since
24163 back end cannot handle this case)
24165 2005-09-01 Robert Dewar <dewar@adacore.com>
24167 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24168 error msgs for most common cases.

24171 2005-09-01 Javier Miranda <miranda@adacore.com>
24172 Ed Schonberg <schonberg@adacore.com>
24174 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24175 become local to the whole package.
24176 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24177 the package was already analyzed the new algorithm "replaces" the
24178 real entities by the shadow ones. This is required to ensure that
24179 the order of these entities in the homonym chains does not change;
24180 otherwise we can have undefined references at linking time because
24181 in case of conflicts the external name of the entities will have
24182 a suffix that depends on the order of the entities in the chain.
24183 (Remove_Limited_With_Clause): Complementary code that completes the
24184 new algorithm and replaces the shadow entities by the real ones.
24185 (Install_Limited_Withed_Unit): When unchaining entities before the
24186 installation of the shadow entities, only regular entities of the
24187 public part must be taken into account. This is required to
24188 keep this routine in synch with the work done by Remove_Limited_
24190 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24191 even if unit is analyzed, because the analysis of the unit is
24192 idempotent in any case, and the limited view of the unit may have to
24193 be installed for proper visibility.
24194 (Expand_Limited_With_Clause): Even if the unit in the implicit
24195 with_clause has been analyzed already, a limited view of the package
24196 must be built for the current context, if it does not exist yet.
24198 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24199 Javier Miranda <miranda@adacore.com>
24200 Gary Dismukes <dismukes@adacore.com>
24202 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24203 defining entity for the instance body, make a new defining identifier
24204 rather than copying the entity of the spec, to prevent accidental
24205 sharing of the entity list.
24206 (Check_Private_View): When exchanging views of private types, build the
24207 list of exchanged views as a stack, to ensure that on exit the exchanges
24208 are undone in the proper order.
24209 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24210 Restore the compilation environment in case of instantiation_error.
24211 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24212 for an anonymous access result.
24213 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24214 (Formal_Entity): Handle properly the case of a formal package that
24215 denotes a generic package renaming.
24217 2005-09-01 Thomas Quinot <quinot@adacore.com>
24219 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the

24225 Javier Miranda <miranda@adacore.com>
24227 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24229 to check if a type is Constrained in cases related to code generation
24230 (rather than semantic checking) since otherwise we do not generate
24231 similar code for mutable private types depending if their
24232 discriminants are visible or not.
24233 (Check_Abstract_Overriding): Do not complain about failure to override
24234 the primitive operations used in dispatching selects since they will
24235 always be overriden at the freeze point of the type.
24236 (Access_Definition): Separate out handling for resetting the scope
24237 of an anonymous access function result type. Retrieve the scope
24238 of the associated function rather than using Current_Scope, which
24239 does not have a consistent value (depends on whether we're in the
24240 middle of analyzing formal parameters). Add ??? comment about
24241 finding a cleaner way to handle the special cases of scope setting.
24242 (Process_Incomplete_Dependents): A protected operation is never a
24243 dispatching operation (only its wrapper may be).
24244 (Build_Derived_Record_Type): In case of tagged private types that
24245 implement interfaces add derivation of predefined primitive
24247 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24248 by two parameters that are used in case of derivation from abstract
24249 interface types: No_Predefined_Prims is used to avoid the derivation
24250 of predefined primitives from the interface, and Predefined
24251 Prims_Only is used to complete the derivation predefined primitives
24252 in case of private tagged types implementing interfaces.
24253 Fix typo in comments
24254 (Find_Interface_In_Descendant): Protect the frontend against
24255 wrong code with large circularity chains.
24256 (Is_Private_Overriding): Add support for entities overriding interface
24257 subprograms. The test failed because Entities associated with overriden
24258 interface subprograms are always marked as hidden (and used to build
24259 the secondary dispatch table); in this case the overriden entity is
24260 available through the field abstract_interface_alias (cf. override_
24261 dispatching_operation)
24262 (Access_Definition): Set the scope of the type to Current_Scope for the
24263 case of a function with an anonymous access result type.
24264 (Access_Subprogram_Declaration): Handle creation of the type entity for
24265 an access-to-function type with an anonymous access result.
24266 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24267 in handling for N_Access_Function_Definition.
24268 (Analyze_Subtype_Declaration): Modify the text of error message.
24269 (Derived_Type_Declaration): Modify the text of error message.
24270 (Process_Subtype): Modify the text of error message plus cleanup
24271 of one redundant error message.
24272 (Analyze_Component_Declaration): Code cleanup.
24273 (Analyze_Object_Declaration): Code cleanup.
24274 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24275 attribute in case of access types. Code cleanup.
24276 (Array_Type_Declaration): Code cleanup.
24277 (Process_Discriminants): Create the new null-excluding itype
24278 if required. Code cleanup.
24279 (Process_Subtype): Create the new null-excluding itype if
24280 required. Code cleanup.
24281 (Build_Derived_Record_Type): Code cleanup to avoid calling
24282 twice the subprogram derive_subprograms in case of private
24283 types that implement interfaces. In this particular case the
24284 subprogram Complete_Subprograms_Derivation already does the
24285 job associated with the second call.
24287 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24288 conversion to the full view when generating an operation for a
24289 discriminant whose type may currently be private.
24291 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24292 Javier Miranda <miranda@adacore.com>
24294 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24295 V (Obj.F), the rewriting does not involve the indexed component, but
24296 only the selected component itself.
24297 Do not apply the transformation if the analyzed node is an actual of a
24298 call to another subprogram.
24299 (Complete_Object_Operation): Retain the entity of the
24300 dispatching operation in the selector of the rewritten node. The
24301 entity will be used in the expansion of dispatching selects.
24302 (Analyze_One_Call): Improve location of the error message associated
24304 (Analyze_Selected_Component): No need to resolve prefix when it is a
24305 function call, resolution is done when parent node is resolved, as
24307 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24308 when attempting to resolve a call transformed from its object notation.
24309 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24310 of the argument list for each interpretation of the operation.
24311 (Try_Object_Operation): The designated type of an access parameter may
24312 be an incomplete type obtained through a limited_with clause, in which
24313 case the primitive operations of the type are retrieved from its full
24315 (Analyze_Call): If this is an indirect call, and the return type of the
24316 access_to_subprogram is incomplete, use its full view if available.
24318 2005-09-01 Javier Miranda <miranda@adacore.com>
24319 Gary Dismukes <dismukes@adacore.com>
24321 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24322 access types the null-exclusion and access-to-constant attributes must
24324 (Analyze_Return_Statement): When the result type is an anonymous access
24325 type, apply a conversion of the return expression to the access type
24326 to ensure that appropriate accessibility checks are performed.
24327 (Analyze_Return_Type): For the case of an anonymous access result type,
24328 generate the Itype and set Is_Local_Anonymous_Access on the type.
24329 Add ??? placeholder for check to disallow returning a limited object
24330 in Ada 2005 unless it's an aggregate or a result of a function call.
24331 Change calls from Subtype_Mark to Result_Definition.
24332 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24333 Result_Definition in call to Make_Function_Specification.
24334 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24335 Set_Result_Definition.
24336 (Make_Inequality_Operator): Change formal Subtype_Mark to
24337 Result_Definition in call to Make_Function_Specification.
24338 (Process_Formals): Create the new null-excluding itype if required.
24339 (New_Overloaded_Entity): For an entity overriding an interface primitive
24340 check if the entity also covers other abstract subprograms in the same
24341 scope. This is required to handle the general case, that is, overriding
24342 other interface primitives and overriding abstract subprograms inherited
24343 from some abstract ancestor type.
24344 (New_Overloaded_Entity): For an overriding entity that comes from
24345 source, note the operation that it overrides.
24346 (Check_Conformance, Type_Conformant): Addition of one new formal
24347 to skip controlling formals in the analysis. This is used to
24348 handle overloading of abstract interfaces.
24349 (Base_Types_Match): Add missing case for types imported from
24350 limited-with clauses
24351 (New_Overloaded_Entity): Add barrier to protect the use of
24352 the "alias" attribute.
24354 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24356 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24357 verify that the procedure and the entry are mode conformant.
24358 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24359 as a different operator, which is often a cut-and-paste error.
24361 2005-09-01 Javier Miranda <miranda@adacore.com>
24362 Ed Schonberg <schonberg@adacore.com>
24364 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24365 used in controlling parameters exclude null because it is necessary to
24366 read the tag to dispatch, and null has no tag.
24367 (Override_Dispatching_Operation): If the previous operation is inherited
24368 from an interface, it becomes hidden and does not participate in later
24371 2005-09-01 Javier Miranda <miranda@adacore.com>
24372 Ed Schonberg <schonberg@adacore.com>
24373 Gary Dismukes <dismukes@adacore.com>
24375 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24376 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24377 the expander will generate the corresponding run-time check to evaluate
24379 (Resolve_Call): Check for legal type of procedure name or prefix that
24380 appears as a trigger in a triggering alternative.
24381 (Valid_Conversion): If expression is ambiguous and the context involves
24382 an extension of System, remove System.Address interpretations.
24383 (Resolve_Qualified_Expression): Reject the case of a specific-type
24384 qualification applied to a class-wide argument. Enhance comment
24385 to explain checking of Original_Node.
24386 (Resolve_Type_Conversion): The location of the error message was not
24387 general enough to handle the general case and hence it has been removed.
24388 In addition, this patch improves the text of the message.
24389 (Resolve_Type_Conversion): Add missing support for access to interface
24391 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24392 do not expand if the expression is the actual in a call, because proper
24393 expansion will take place when the call itself is expanded.
24394 (Resolve_Allocator): If the context is an unchecked conversion, the
24395 allocator inherits its storage pool, if any, from the target type of
24398 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24399 Javier Miranda <miranda@adacore.com>
24401 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24402 inherited interface operation that has an implementation, use the
24403 implementation to avoid spurious ambiguities.
24404 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24405 use the Corresponding_Record_Typ attribute to look for the interface
24406 because it is set by the expander (and hence it is not always
24407 available). For this reason we traverse the list of interfaces
24408 (available in the parent of the concurrent type).
24409 (Interface_Present_In_Ancestor): Handle entities from the limited view
24411 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24413 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24414 from the list of required components.
24415 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24416 primitive procedure of a limited interface with a controlling first
24418 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24420 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24421 capture if it is generated in the second operand of a short-circuit
24423 Do not capture values for variables with address clauses.
24424 (Is_Object_Reference): Treat a function call as an object reference only
24425 if its type is not Standard_Void_Type.
24427 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24429 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24430 to a variable that is statically known to be constant.
24432 2005-09-01 Geert Bosch <bosch@adacore.com>
24433 Robert Dewar <dewar@adacore.com>
24435 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.

24447 Document new treatment of wide characters in max line length
24449 Remove -gnatL/-gnatZ switches, no longer used.
24450 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

24454 Float_Representation.
24455 Add documentation for pragma No_Strict_Aliasing
24456 Add note that explicit component clause overrides pragma Pack.

25212 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25213 longer protected objects. They have been replaced by lower-level
25214 suspension objects made up by a mutex and a condition variable (or
25215 their equivalent given a particular OS) plus some internal data to
25216 reflect the state of the suspension object.
25217 (Initialize, Finalize): Add this initialization procedure for
25218 Suspension_Object, which is a controlled type.
25219 (Finalize): Add the finalization procedure for Suspension_Object,
25220 which is a controlled type.
25222 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

25229 (InitializeCriticalSection, EnterCriticalSection,
25230 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25231 pCriticalSection by an anonymous access type so that we avoid problems
25232 of accessibility to local objects.

25239 set the environment task mask here.
25240 (Current_State): Add this function that returns the state of the
25242 (Set_False): Add this procedure that sets the state of the suspension
25244 (Set_True): Add this procedure that sets the state of the suspension
25245 object to True, releasing the task that was suspended, if any.
25246 (Suspend_Until_True): Add this procedure that blocks the calling task
25247 until the state of the object is True. Program_Error is raised if
25248 another task is already waiting on that suspension object.
25249 (Initialize): Add this procedure for initializing the suspension
25250 object. It initializes the mutex and the condition variable which are
25251 used for synchronization and queuing, and it sets the internal state
25253 (Finalize): Add this procedure for finalizing the suspension object,
25254 destroying the mutex and the condition variable.

25259 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25260 which provides a low-level abstraction (using operating system
25261 primitives) for Ada.Synchronous_Task_Control.
25262 This object is made up by a mutex (for ensuring mutual exclusion), a
25263 condition variable (for queuing threads until the condition is
25264 signaled), a Boolean (State) indicating whether the object is open,
25265 and a Boolean (Waiting) reflecting whether there is a task already
25266 suspended on this object.

25678 access to subprograms must be recursive.
25679 (Is_Unchecked_Conversion): Improve the test that recognizes
25680 instantiations of Unchecked_Conversion, and allows them in bodies that
25681 are to be inlined by the front-end. When the body comes from an

25708 way as a normal component of an anonymous access type.
25709 (Resolve_Allocator): When an allocator's designated type is a class-wide
25710 type, check that the accessibility level of type given in the
25711 allocator's expression or subtype indication is not statically deeper

25731 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25732 check on possible violation of restriction No_Direct_Boolean_Operators

26739 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26740 of using Set_Renaming_TSS. This ensures that the TSS bodies are not

26742 error messages if expansion has been disabled due to previous
26743 (unrelated) errors).
26745 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26746 is disabled, the entity denoted by the argument is the access type
26747 itself, not an underlying record type, so there is no need to go back
26748 to the Corresponding_Remote_Type.

26758 denotes a type in the class.
26759 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26760 of Name_Generic_Dispatching_Constructor.
26762 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26763 05 unit for AI-260-02).

26777 the case of renaming of stream attributes when the renaming denotes a
26778 generic formal subprogram association for an abstract formal subprogram.
26779 Check that the attribute is a primitive stream attribute (and not
26780 a class-wide stream attribute) and then rewrite the attribute name
26781 as the name of the appropriate compiler-generated stream primitive.

26785 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26793 itype whose parent is controlled and not yet frozen, do not create a
26794 freeze node for the itype if expansion is disabled.
26796 2005-03-29 Vincent Celier <celier@adacore.com>
26798 * make.adb (Gnatmake): Don't fail if the main project file is declared
26799 as having no Ada sources. Do not display message "no sources to
26800 compile" in quiet output.
26802 2005-03-29 Doug Rupp <rupp@adacore.com>
26804 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26820 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26821 rather than proceed ahead using a junk attribute name.
26823 2005-03-29 Vincent Celier <celier@adacore.com>
26825 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26827 * prj-part.adb (Parse_Single_Project): Set the location of a project
26828 on its defining identifier, rather than on the reserved word "project".
26830 * prj-proc.adb (Expression): Adapt to the fact that default of external
26831 references may be string expressions, not always literal strings.
26832 (Recursive_Process): Set Display_Name equal to Name
26833 when Location is No_Location, that is when there is no actual file.
26834 Get the Display_Name of the project from the source, when it is not a
26836 (Process): Use the Display_Name in error messages
26838 * prj-strt.adb (External_Reference): Allow default to be string

27501 Update documentation on Must_Be_Byte_Aligned for new spec
27503 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27504 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27505 uses of the Access_Disp_Table attribute to reference the first dispatch
27506 table associated with a tagged type. As
27507 part of the implementation of abstract interface types,
27508 Access_Disp_Table has been redefined to contain a list of dispatch
27509 tables (rather than a single dispatch table).
27510 Similarly, upgrade all the references to Tag_Component by the
27511 new attribute First_Tag_Component.
27512 (Find_Inherited_TSS): Moved to exp_tss.
27513 Clean up test in Expand_N_Object_Declaration for cases
27514 where we need to do a separate assignment of the initial value.

27516 declaration of a tagged type is an aggregate, no need to generate an
27517 additional tag assignment.
27518 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27520 Bit packed array ops are only called if operands are known to be
27522 (Component_Equality): When returning an N_Raise_Program_Error statement,
27523 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27524 expects that only expressions have a bona fide type).
27525 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27526 determine the amount of data to be copied.
27528 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27529 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27556 (Task_Body_Procedure): Removed.
27557 (Set_Task_Body_Procedure): Removed.
27558 These subprogram have been removed because the attribute
27559 Task_Body_Procedure has been moved to the corresponding task type
27560 or task subtype entity to leave a field free to store the list
27561 of interfaces implemented by a task (for AI-345)
27562 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27563 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27564 expression flag Do_Range_Check
27565 (Exception_Junk): Change to Flag7 to accomodate above change

27572 "with string" given.
27574 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27577 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27580 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27581 attribute Task_Body_Procedure rather than the old semantic field that
27582 was available in the task_type_declaration node.
27584 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27585 interface type definitions.
27586 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27589 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27590 task type declaration.

27592 protected type declaration.
27594 2005-03-15 Doug Rupp <rupp@adacore.com>
27595 Vincent Celier <celier@adacore.com>
27597 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27598 (Gen_Output_File_C): Likewise.

27603 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27604 is an N_Raise_Constraint_Error node, create a new copy of it without
27605 going through a call to Duplicate_Subexpr.

27618 size of their types.
27619 (gnat_to_gnu_entity, case E_Component): Always look at
27620 Original_Record_Component if Present and not the entity.
27621 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27622 of tagged extension types by not making field for components that are
27624 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27625 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27626 expression to the type of the object when the object is constant.
27627 Reverse defer_debug_incomplete_list before traversing it, so that trees
27628 are processed in the order at which they were added to the list. This
27629 order is important when using the stabs debug format.
27630 If we are deferring the output of debug information, also defer this
27631 output for a function return type.
27632 When adding fields to a record, prevent emitting debug information
27633 for incomplete records, emit the information only when the record is
27635 (components_to_record): New parameter defer_debug.
27636 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27637 (gnat_to_gnu_field_decl): New function.

27639 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27640 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27641 No longer update discriminants to not be a COMPONENT_REF.
27642 (copy_alias_set): Strip padding from input type; also handle
27643 unconstrained arrays properly.
27645 * gigi.h (write_record_type_debug_info): New function.
27646 Convert to use ANSI-style prototypes. Remove unused
27647 declarations for emit_stack_check, elab_all_gnat and

27657 converting to an unchecked union type.
27659 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27660 replace the N_Freeze_Entity with a null statement.
27662 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27663 within a constrained subcomponent of an enclosing record, place the

27666 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27667 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27668 within records; allow them to have freeze nodes if their base types
27671 * exp_util.adb (Remove_Side_Effects): Properly test for
27672 Expansion_Delayed and handle case when it's inside an
27673 N_Qualified_Expression.
27675 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27676 Comes_From_Generic, to recognize accurately that the parent type in a
27677 derived type declaration can be traced back to a formal type, because
27678 it is one or is derived from one, or because its completion is derived
27680 (Constrain_Component_Type): If component comes from source and has no
27681 explicit constraint, no need to constrain in in a subtype of the
27683 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27684 Minor change to propagate Is_Ada_2005 flag
27686 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27687 Expansion_Delayed is False.
27688 (assoc_to_constructor): Ignore fields that have a
27689 Corresponding_Discriminant.
27690 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27691 function returns "by target", dereference the target pointer using the
27692 type of the actual return value.
27693 <all>: Be prepared for a null gnu_result.
27694 (processed_inline_subprograms): Check flag_really_no_inline

27706 Must_Be_Byte_Aligned for cases where we do not need to use a
27707 System.Pack_nn unit.
27709 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27711 Needed now that we do some processing for IN parameters as well. This
27712 may well fix some unrelated errors.
27713 (Expand_Call): Handle case of unaligned objects (in particular those
27714 that come from packed arrays).
27715 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27716 renamed entity is an inherited operation, re-expand the call using the
27717 original operation, which is the one to call.
27718 Detect attempt to inline parameterless recursive subprogram.
27719 (Represented_As_Scalar): Fix to work properly with private types
27720 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27721 accurate estimate. Yields True in far fewer cases than before,
27722 improving the quality of code that depends on this test.
27724 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27725 over both visible and private declarations to remove them from tree,
27726 and mark subprograms declared in package as eliminated, to prevent
27727 spurious use in subsequent compilation of generic units in the context.
27729 * exp_util.ads: Minor cleanup in variable names
27731 * sem_eval.ads, sem_eval.adb: Minor reformatting
27732 (Compile_Time_Known_Bounds): New function

27736 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27737 determining whether an unchecked conversion is needed for the argument
27738 of an initialization call.
27740 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27742 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27743 that appears in the instantiation rather than the internal subtype
27744 generated in the wrapper package, to avoid anomalies in gigi when the
27745 target is derived from a private type whose full view is an access type.
27747 2005-03-15 Robert Dewar <dewar@adacore.com>
27749 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27751 Add documentation to replace the use of this flag
27752 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27755 2005-03-15 Thomas Quinot <quinot@adacore.com>
27757 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27758 here from exp_attr so it can be shared between exp_attr and exp_dist.
27759 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27760 all TSS names, not a subset thereof, and the previous name introduced
27761 an unnecessarily confusion that a distinction might exist between
27762 "OK" TSS names and some "not OK" TSS names.
27764 2005-03-15 Doug Rupp <rupp@adacore.com>
27766 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27769 2005-03-15 Pascal Obry <obry@adacore.com>
27770 Eric Botcazou <ebotcazou@adacore.com>
27774 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27775 when IN_RTS. This is to work around a bootstrap path problem.
27777 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27778 table and pass it to __gnat_install_SEH_handler().
27779 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27781 * lang.opt: Fix specification of -fRTS=.
27783 2005-03-15 Doug Rupp <rupp@adacore.com>

27785 Vincent Celier <celier@adacore.com>
27786 Arnaud Charlet <charlet@adacore.com>
27789 This change works fine when gnatlib is built from the gcc directory,
27790 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27791 is not passed to ada/Makefile.in, so more work is needed by a
27792 Makefile/configure expert.
27794 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27795 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27796 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27798 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27799 Run ranlib on libgccprefix.a
27800 Define PREFIX_OBJS for Darwin, to build libgccprefix.

27803 2005-03-15 Robert Dewar <dewar@adacore.com>
27805 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27807 * impunit.adb: Add GNAT.UTF_32
27809 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27811 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27812 now uses GNAT.UTF_32).

27826 Ed Schonberg <schonberg@adacore.com>
27828 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27829 parameter reported some error we immediately return. This improves the
27830 behaviour of the frontend in case of errors.
27831 (Install_Parent, Remove_Parent): Introduce new flag
27832 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27833 ancestor of a generic child unit, when the child is being instantiated.
27834 (Inline_Instance_Body): If we are compiling the private
27835 part or the body of a child unit, restore the proper visibility of the
27836 parents after compiling the instance body.

27839 Javier Miranda <miranda@adacore.com>
27842 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27843 of a private type, in which case it is underlying_type that denotes
27844 the proper task. Also modified to use the new entity attribute
27845 that is directly available in the task type and task subtype entities
27846 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27847 arrays when other dimensions than the first are constrained by
27848 discriminants of an enclosing record.
27849 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27850 a combination of indexed and selected components, find ultimate entity
27851 and generate the appropriate reference for it, to suppress spurious
27853 (Note_Possible_Modification): If an entity name has no entity, return.
27854 (Is_Variable): A function call never denotes a variable.
27855 (Requires_Transient_Scope): For record types, recurse only on

27861 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27862 Eliminated as candidates for resolution. Both efficient, and avoids
27863 anomalies with operators declared in deleted code.
27864 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27865 expansion is disabled (as when compiling a generic) to prevent spurious
27866 warnings on prefixes of selected components.
27868 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27870 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27871 attached to a list before checking whether it appears in the private
27872 declarations of the current package.
27873 (Make_Inequality_Operator): Insert declaration in proper declarative
27874 list rather than just setting the Parent field, so that
27875 Is_Private_Declaration can handle it properly.
27877 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27879 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27880 a renaming a body, check that the renamed subprogram in not intrinsic.
27881 (Find_Direct_Name): If several use_visible entities hide
27882 each other, and the context is a predefined file compiled through
27883 rtsfind, keep only the entity that comes from a predefined file.
27885 2005-03-15 Geert Bosch <bosch@adacore.com>
27887 * s-fatgen.adb (Valid): Extend special exceptions to account for long

28282 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28283 Remove ["0A"] from comment, since it can look like a line terminator.
28284 Currently we don't permit this, but this is under discussion by the
28285 ARG, and it is easy enough to use a different example.
28287 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28288 handling UTF-32 encoding for wide wide character.
28289 Implement new brackets coding ["hhhhhhhh"]

28295 bit range Add full UTF-32 support.
28296 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28297 notify that constraint error will be raised at run-time
28298 because a null value is assigned to a null-excluding object.
28299 Remove some obsolete declarations and make Char_Code
28302 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28303 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28304 Rcheck subprograms.
28306 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28307 wrong null-exclusion value by a warning message.
28308 (Enable_Range_Check): Do range check if the prefix is an
28309 explicit dereference whose designated object is an unconstrained array.
28310 Current algorithm for removing duplicate checks is over-eager in this
28313 * sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
28314 null-exclusion value by a warning message
28316 * atree.h, atree.ads, atree.adb: Remove Char_Code field support
28317 completely. Add support for Uint2 field

28322 * exp_util.adb (Insert_Actions): Replace
28323 N_Formal_Subprogram_Declaration by
28324 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
28325 Char_Literal_Value field is now a Uint.
28327 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28328 defined for subprogram renaming declarations. When set, the field
28329 indicates the defining entity of a corresponding formal subprogram
28330 when the renaming corresponds to a formal subprogram association in an
28332 (Set_Corresponding_Formal_Spec): New procedure to return
28333 Corresponding_Formal_Spec field.
28334 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28335 (which is now a subtype).
28336 Char_Literal_Value field is now a Uint
28338 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28339 pointer to the base of the dispatch table.
28340 Minor changes to comments.
28341 (Controlling_Type): New function for determining the tagged type
28342 associated with a tagged primitive subprogram.
28343 (Expand_Dispatching_Call): Add support for a controlling actual that is
28344 directly a value of type Ada.Tag rather than a tagged object.
28346 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28347 describing the new layout.
28348 (Dispatch_Table): The expander computes the actual array size, allocates
28349 the Dispatch_Table record accordingly, and generates code that displaces
28350 the base of the record after the Typeinfo_Ptr component. The access to
28351 these components is done by means of local functions.
28352 (Offset_To_Top): New function.
28353 (Typeinfo_Ptr): New function.
28354 (Get_TSD): Modified to access the new position of the TSD.
28355 (Set_TSD): Modified to save the TSD in its new position.
28357 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28358 case of formal abstract subprograms. Add check and message for -gnat05.
28361 * sem_ch12.adb: Add with and use for Sem_Disp.

28365 N_Formal_Subtype_Declaration (which is now a subtype).
28366 (Analyze_Formal_Subprogram): Add handling for
28367 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28368 dispatching, setting the controlling status of the formal parameters
28369 and result, and issuing an error if there is no controlling type for
28370 the formal subprogram.
28371 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28372 which is an unclean use of that field, we set the new field
28373 Corresponding_Formal_Spec to make the formal subprogram available to
28374 processing in Analyze_Subprogram_Declaration.
28375 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28376 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28377 Constrained, so that it is is does not statically match its anonymous
28380 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28381 abstract formal subprograms in error check for functions returning
28382 abstract types. Set scope of new designator for
28383 a parameterless subprogram, so that it is available when checking the
28384 body for nested subprograms, before full analysis of said body.
28385 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28386 subprogram only if inner one comes from source.
28387 (Analyze_Function_Call): If the call is given in object notation, the
28388 analysis of the name rewrites the node and analyzes it with the proper
28389 argument list. After analyzing the name, if the call has been rewritten
28390 and the result type is set, no further analysis is needed.
28391 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28392 mark in function specification, in a context where the formals are
28393 visible and hide outer homographs.
28395 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28396 as the tagged type for the cases of abstract formal subprograms and
28397 renamings of those. Clean up spec comments.
28398 (Check_Dispatching_Context): Add error message to indicate "abstract
28399 procedure", covering the case of a call to a formal abstract procedure
28400 that has statically tagged operands.
28401 (Check_Dispatching_Call): Check for the case of an actual given by
28402 a tag-indeterminate function call whose type is an ancestor of the
28403 containing call's associated tagged type. This situation can occur
28404 for inherited primitives with function defaults. In this case we
28405 use the tagged type's tag directly as the controlling argument for
28407 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28409 * sprint.adb (Sprint_Node_Actual): Split
28410 N_Formal_Subprogram_Declaration into two alternatives for the new
28411 cases N_Formal_Abstract_Subprogram_Declaration and

28472 GNAT.OS_Lib.Set_Close_On_Exec.
28474 * g-expect.adb (Set_Up_Communications): Mark the pipe descriptors for
28475 the parent side as close-on-exec so that they are not inherited by the

28482 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28486 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28487 on the field if Pragma Component_Alignment (Storage_Unit).
28488 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28489 side-effects as if it were a constant; also make SAVE_EXPR to protect
28491 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28493 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28494 (components_to_record): Test it.

28507 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28509 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28510 component of an array of arrays in an assignment context, and the
28511 aggregate has component associations that require sliding on
28512 assignment, force reanalysis of the aggregate to generate a temporary
28513 before the assignment.
28514 (Must_Slide): Make global to the package, for use in Gen_Assign.
28516 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28518 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28519 unchecked union with no inferable discriminants, return a
28520 Raise_Program_Error node, rather than inserting it at the point the
28522 (Expand_Record_Equality, Component_Equality): Handle properly the case
28523 where some subcomponent is an unchecked union whose generated equality
28524 code raises program error.
28526 2005-02-09 Doug Rupp <rupp@adacore.com>
28528 * gnatbl.c: [VMS] (_POSIX_EXIT): Define.

28532 Arnaud Charlet <charlet@adacore.com>
28534 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28535 address of the exception registration. The Win32 version of this
28536 routine calls __gnat_install_SEH_handler() to initialize the SEH
28537 (Structured Exception Handling) handler.
28538 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28539 SEH (Structured Exception Handling) now.
28540 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28541 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28542 preprocessor condition protecting the call to the extra eh setup
28543 subprogram, which is only available for the ppc target.
28544 (__gnat_clear_exception_count): replaced reference to
28545 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28547 * seh_init.c: New file.
28549 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28550 (GNATBIND_OBJS): Idem.
28552 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28553 routine takes a new parameter (a pointer to the exception registration
28554 for the SEH (Structured Exception Handling) support.
28556 * raise.h: (__gnat_install_SEH_handler): New prototype.
28557 Update copyright notice.
28559 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28560 record and initialize it by calling __gnat_install_SEH_handler.

28570 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28571 [VMS]: Add translations for g-enblsp.adb.
28573 * s-asthan-vms.adb: Removed.
28574 * s-asthan-vms-alpha.adb: Added.
28576 2005-02-09 Pascal Obry <obry@adacore.com>
28578 * Makefile.in (LIBGNAT_SRCS): Add seh_init.c.

28581 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28584 * Makefile.in: Link all gnat tools with -static-libgcc, since
28585 -shared-libgcc is now used by default on some systems (e.g. linux with
28587 Remove references to Makefile.prolog/generic, no longer used.
28589 2005-02-09 Vincent Celier <celier@adacore.com>
28591 * prj-makr.adb (Process_Directory): Put file name in canonical case
28592 before matching against the patterns.
28593 If gnatname has been invoked as <prefix>-gnatname
28594 then invoke the compiler as <prefix>-gcc, not just "gcc".
28596 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28598 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28599 with expansion disabled. The actual subtype is needed among other
28600 places when the selected component appears in the context of a loop
28601 bound, and denotes a packed array.
28602 (Operator_Check): Always use the first subtype in the
28603 error message, to avoid the appearance of internal base types.
28604 (Transform_Object_Operation): Copy each actual in full
28605 to the parameter associations of the constructed call, rather than
28606 using the shallow copy mechanism of New_Copy_List. This ensures that
28607 the chaining of named associations is done properly.
28608 (Complete_Object_Operation): Rewrite node, rather than
28609 replacing it, so that we can trace back to the original selected
28612 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28613 and calls that use object notation, if the called function is not
28614 declared in a withed unit, place the elaboration constraint on the
28615 unit in the context that makes the function accessible.
28616 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28617 imposes an elaboration constraint between two packages.
28619 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28621 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28622 views of a private type after handling its private dependents, to
28623 maintain proper stack discipline between entry and exit from the
28626 2005-02-09 Cyrille Comar <comar@adacore.com>

28639 recursion warnings when compiled with -gnatdm.
28641 2005-02-09 Robert Dewar <dewar@adacore.com>
28643 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28644 Slight fix to documentation of -gnaty with no parameters
28646 * xr_tabls.ads: Add ??? comment for missing overall comment
28648 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28649 we now use by default.
28651 * xsnames.adb: Adjust end of file test to look for five space followed
28652 by '#' instead of six spaces. The format of xsnames.adb was modified
28653 in the last update.
28655 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28658 * clean.adb: Minor reformatting.
28660 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28661 gnatname.adb: Minor reformatting
28662 Add 2005 to copyright output when utility is run
28664 * csets.adb: Eliminate obsolete comment
28666 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28669 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28671 2005-02-09 Sergey Rybin <rybin@adacore.com>
28673 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28674 the difference between compact and incompact layout and add the record
28675 representation clause to the example illustrating different layouts.
28676 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28677 component clauses").
28679 2005-02-09 Florian Villoing <villoing@adacore.com>
28681 * gnat_ugn.texi: Fix typos.
28682 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28684 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28685 in the generated documentation.
28687 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28689 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no
28691 Update linker wrapper when linking with non GNU C++.
28693 2005-02-09 Pascal Obry <obry@adacore.com>
28696 Document the procedure to debug the DllMain routine on Windows.
28697 Add note about -funwind-tables and mixed Ada and C/C++ programming in
28699 Document new BIND qualifer /RETURN_CODES=VMS.

28719 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
28720 from the VxWorks kernel) that is needed for getting the active
28721 priority of the different tasks.
28723 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28724 Use a pragma Elaborate_Body in the spec file instead.
28725 Noticed by code reading.
28727 2005-02-09 Thomas Quinot <quinot@adacore.com>
28729 * exp_util.ads: Minor correction in comment.
28731 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28733 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28734 since this procedure is now too complex to be worth inlining.
28736 2005-02-09 Richard Henderson <rth@redhat.com>
28738 * utils.c (gnat_define_builtin): Remove.
28739 (gnat_install_builtins): Use build_common_builtin_nodes.

29154 note that it applies to obsolete GNAT features, which was previously
29155 omitted. Second we contrast the behavior with that of the new
29156 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29157 Preliminary rewriting of GNAT & libraries chapter in order to take

29389 "no bitfield creation", to be used by make_aligning_type. Don't
29390 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29391 fields claimed addressable still have to be bitfields. Use
29392 value_factor_p instead of a raw binop construction to check for the
29393 position's alignment.

29400 Ed Schonberg <schonberg@adacore.com>
29402 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29403 with an implicit dereference as its prefix, use
29404 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29406 prefix is generated, if appropriate.
29408 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29409 dereference is rewritten to an explicit one, generate a reference to
29410 the entity denoted by its prefix using the original prefix node, so

29412 access value, if appropriate.
29414 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29415 emitting 'assigned but never read' warning on a variable on the basis

29429 an external name, to be handled by the back end.
29431 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29432 subprogram which is Imported with convention Intrinsic if an
29433 External_Name argument is specified.
29434 (Process_Import_Or_Interface): Properly diagnose link name argument.
29435 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29460 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29461 PCS-specific part of Add_Stub_Type.

29488 (Generate_Reference): Handle properly a reference to an entry formal,
29489 when an accept statement has a pragma Unreferenced for it.
29491 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29492 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29493 the body, to ensure that warnings are properly emitted for each accept
29494 statement of a given task entry.

29516 (Remove_Next_Debug): Same fix
29518 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

29522 (Remove_Next): Same cleanup
29524 2004-12-07 Thomas Quinot <quinot@adacore.com>
29526 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29527 used to record an implicit dereference as a read operation on its
29528 prefix when operating under -gnatc. Necessary to avoid spurious
29529 'variable assigned but never read' warnings in that mode.
29530 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29531 is a non-overloaded implicit dereference, call the above subprogram to
29532 ensure proper recording of references.
29534 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29536 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29537 to be resolved later as part of Analyze_Iteration_Scheme's call to

29584 2004-12-07 Vincent Celier <celier@adacore.com>
29586 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29587 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29588 and -eit to -ept. Added qualifier
29589 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29591 2004-11-27 Andreas Schwab <schwab@suse.de>
29593 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29595 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29597 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29598 internal implementation unit GNAT.Sockets.Thin,
29599 as their usage for sockets is non-portable (using the read and write
29600 functions from the system runtime library is fine on UNIX but won't
29601 work under Windows).
29603 * mingw32.h: Update copyright notice.
29605 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29657 new Others_Value and All_Others_Value objects.
29658 (struct attrib): Rename "arg" component as "args", since GCC expects a
29659 list of arguments in there.
29661 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29662 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29665 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29666 others_decl and all_others_decl instead of hardcoded dummy addresses
29667 to represent "others" and "all others" choices, which is cleaner and
29668 more flexible with respect to the possible eh pointer encoding policies.
29670 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29671 (process_attributes): Account for the naming change of the "args"
29672 attribute list entry component.
29674 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29675 cumulating attributes for different entities into a single list.
29676 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29677 attributes for the current entity and propagate first subtype
29678 attributes to other subtypes.
29679 <E_Procedure>: Attribute arguments are attr->args and not
29680 attr->arg any more.
29681 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29682 argument provided, as this is what GCC expects. Use NULL_TREE instead
29685 2004-11-18 Robert Dewar <dewar@adacore.com>
29687 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29720 (First_RCI_Subprogram_Id): Document this constant.
29721 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29723 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29724 replaced with calls to Get_Library_Unit_Name_String. Previously there
29725 were several instances of the same code in different locations in the
29726 compiler; this checkin completes the replacement of all of these
29727 instances with calls to a common subprogram.
29728 Minor reformatting.

29761 that the pragmas are properly attached to the tree, and that no
29762 nodes are improperly shared.
29764 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29765 pragmas to Exp_Prag, which is more appropriate.
29766 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29767 check for duplicates Remove use of Is_Psected flag, no longer needed.
29768 Use new Make_String_Literal function with string.
29770 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29771 that are functions return universal values, that have to be converted
29772 to the context type.
29773 Use new Make_String_Literal function with string.
29774 (Get_Stream_Convert_Pragma): New function, replaces the use of
29775 Get_Rep_Pragma, which had to be kludged to work in this case.
29777 * freeze.adb: Use new Has_Rep_Pragma function
29779 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29780 function with string.
29781 Use new Has_Rep_Pragma function.
29783 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29786 2004-11-18 Robert Dewar <dewar@adacore.com>
29788 * errout.ads, errout.adb: (First_Sloc): New function
29790 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29791 check (-gnatyx) instead of being included as a redundant construct
29794 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29795 Style_Check_Order_Subprograms.
29797 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29798 stylesw.adb: Add Style_Check_Xtra_Parens
29800 * usage.adb: Add line for -gnatyx (check extra parens)
29802 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29804 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29805 Robert Dewar <dewar@adacore.com>
29807 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29808 discriminant of a constrained subtype, analyze the copy of the
29809 corresponding constraint, because in some cases it may be only
29810 partially analyzed.
29811 Removes long-lived ??? comments.
29813 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29814 handled controlled or secondary-stack expressions within the
29815 iteration_scheme of a loop.
29817 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29818 bounds that may contain functions calls, to prevent memory leaks when
29819 the bound contains a call to a function that uses the secondary stack.
29820 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29821 generate temporaries for loop bounds that might contain function calls
29822 that require secondary stack and/or finalization actions.
29824 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29825 selected component and the selector is overloadable (not just a
29826 function) treat as function call, Analyze_Call will disambiguate if
29828 (Analyze_Selected_Component): Do not generate an actual subtype for the
29829 selected component if expansion is disabled. The actual subtype is only
29830 needed for constraint checks.
29831 (Analyze_Allocator): If restriction No_Streams is set, then do
29832 not permit objects to be declared of a stream type, or of a
29833 composite type containing a stream.
29835 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29836 No_Streams no longer prohibits with'ing this package.
29838 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29839 discriminants, but the parent base has unknown discriminants, there is
29840 no discriminant constraint to inherit. Such a discrepancy can arise
29841 when the actual for a formal type with unknown discriminants is a
29842 similar private type whose full view has discriminants.
29843 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29844 do not permit objects to be declared of a stream type, or of a
29845 composite type containing a stream.
29847 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29849 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29850 protected operations.
29852 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29853 generated name, it complicates decoding in gdb and hinders debugging
29854 of protected operations.
29855 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29856 flag for the protected entry barrier function.
29857 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29858 flag for the protected entry function.
29860 2004-11-18 Nicolas Setton <setton@adacore.com>
29862 * expect.c: Define __unix__ when __APPLE__ is defined.
29864 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29865 Darwin-specific section.
29867 * lang-specs.h: Change the placement of the %1 marker.
29868 Works around the fact that gcc adds -fPIC by default under Darwin.
29870 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29872 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29873 type of the object with the packed array type, set the Analyzed flag
29874 on the object if it is an entity or simple indexed component, to avoid
29875 spurious type errors.
29877 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29879 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29880 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29881 separate line from the version message.
29883 2004-11-18 Ed Falis <falis@adacore.com>
29885 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29887 (init_float): Eliminate initialization of floating point status for
29888 AE653. The instructions have no effect for vThreads.
29890 2004-11-18 Vincent Celier <celier@adacore.com>
29892 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29893 gnatbind is invoked with -shared.
29895 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29897 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29898 for Detect_Blocking which is redundant with the check done within the
29899 procedure Protected_Single_Entry_Call.
29900 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29901 Detect_Blocking which is redundant with the check done within the
29902 procedure Protected_Single_Entry_Call.
29904 2004-11-18 Vincent Celier <celier@adacore.com>
29906 * makegpr.adb (Compile): Put the compiling switches (in package
29907 Compiler and on the command line) immediately after "-c", instead of
29908 at the end of the command line invocation of the compiler, when
29909 compiling a non-Ada file.
29910 (Build_Global_Archive): When there is no need to rebuild the archive,
29911 set Global_Archive_Exists, so that the archive is passed to the linker
29914 2004-11-18 Robert Dewar <dewar@adacore.com>
29915 Sergey Rybin <rybin@adacore.com>
29918 Remove extra paren check from list of checks for redundant constructs
29919 Add documentation of new -gnatyx style check (check extra parens)
29920 Remove paragraph about gnatelim debug options.
29922 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29923 objects rather than forbidding dependencies on the package Ada.Streams.
29925 * sinfo.ads: Add ??? note that we should document pragmas passed to
29928 * g-expect.ads: Fix a few typos in the comments.
29930 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29932 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29935 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29937 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29939 2004-11-07 Andreas Schwab <schwab@suse.de>
29941 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29943 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29946 * Makefile.in (darwin): Set soext to .dylib.
29948 2004-10-26 Vincent Celier <celier@gnat.com>
29949 Thomas Quinot <quinot@act-europe.fr>
29951 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29952 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29953 there is no use of GNAT.Sockets.Constants.
29954 Remove remaining pragma Import for C_Write
29955 Remove C_Read and C_Write from internal implementation unit
29956 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29957 the read and write functions from the system runtime library is fine
29958 on UNIX but won't work under Windows).
29960 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29961 (Check_Selector): Use C_Recv instead of C_Read.
29962 Selectors are the GNAT.Sockets abstraction to perform a select()
29963 call on a set of descriptors. To allow abortion of an ongoing
29964 select operation, some data is written to a dedicated socket that
29965 is always monitored.
29966 Under Windows, the write and read library functions cannot operate
29967 on sockets, so we need to use send and recv instead, which is portable
29968 across all supported platforms.
29970 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29971 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29972 (using the read and write functions from the system runtime library is
29973 fine on UNIX but won't work under Windows).
29975 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29977 * mlib-tgt-darwin.adb: New file.
29979 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29980 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29981 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29982 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29985 * Makefile.in: Add support for building shared libraries under Darwin.
29986 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29987 the low level EH init subprogram to be called from __gnat_initialize.
29989 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29990 indicates which options to pass to the archive indexer.
29992 * mlib-utl.adb: Add support for calling ranlib with additional
29993 options. This is needed for instance under Mac OS X.
29994 (Ranlib_Options): New global variable, used to store the potential
29995 options to pass to ranlib.
29996 (Ar): Use Ranlib_Options when spawning ranlib.
29997 (Initialize): Set the value of ranlib option.
29999 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30001 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30002 instead of 8K, to reflect the real potential needs for stack-checking
30005 2004-10-26 Pascal Obry <obry@gnat.com>
30007 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30009 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30010 Windows only the initial thread stack size can be set so it is good to
30011 start we a low stack size.
30012 The OS will adjust the size as needed.
30014 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30015 Nicolas Setton <setton@act-europe.fr>
30017 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30018 "__unix__" instead of "unix".
30019 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30020 sections were just mistakenly ignored. The former is
30021 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30022 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30023 of hpux. This prevents an unwanted definition of the symbol
30024 convert_addresses in adaint.o.
30026 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30028 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30029 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30031 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30033 * a-filico.ads, a-filico.adb: fix incorrect header.
30035 2004-10-26 Javier Miranda <miranda@gnat.com>
30037 * a-ststio.ads: Fix typo in identifier
30039 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30041 * sem_ch4.adb: Minor reformatting.
30043 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30045 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30046 enabled, check the result of unary and binary operations when the
30047 expression is the right-hand side of an assignment.
30049 2004-10-26 Vincent Celier <celier@gnat.com>
30051 * clean.adb (Delete): Do not output warnings when in quiet output and
30052 not in verbose mode.
30053 (Force_Deletions): New Boolean flag, defaulted to False
30054 (Delete): Only delete a file if it is writable, and when
30055 Force_Deletions is True.
30056 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30057 (Usage): Line for new switch -f
30058 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30061 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30063 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30064 JM type only if its size matches that of the wrapper. When a size is
30065 prescribed and the field is not aliased, remove the wrapper of a JM
30066 type only if the size is not greater than that of the packed array.
30067 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30070 2004-10-26 Geert Bosch <bosch@gnat.com>
30072 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30073 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30074 (Pred): Implement in terms of Succ.
30076 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30078 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30079 unchecked conversion is safe for in-place use if the expression of the
30080 conversion is safe.
30081 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30082 be expandable in place even if the aggregate does not come from source.
30083 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30084 designated object of an allocator in place, rather than building it
30085 first on the stack. The previous scheme forces a full copy of the array,
30086 and may be altogether unsusable if the size of the array is too large
30087 for stack allocation.
30089 2004-10-26 Robert Dewar <dewar@gnat.com>
30091 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30092 compares if the component is atomic.
30094 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30095 array assignment if the component type is atomic.
30097 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30098 Eric Botcazou <ebotcazou@act-europe.fr>
30100 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30101 is aliased and is a by_reference type, do not pass by copy.
30102 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30103 detect whether the call is in the right side of an assignment or
30104 the expression of an object declaration. Recurse on component
30105 association within aggregates.
30106 Call it in the condition that determines whether the temporary is
30107 necessary for correct stack-checking.
30109 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30111 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30112 RACW_Type, used in the PolyORB version.
30113 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30114 version and the GARLIC version.
30116 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30117 Rename RCI_Info to RCI_Locator for better consistency between the
30118 GARLIC and PolyORB versions of the distributed systems annex.
30119 (DSA_Implementation_Name): This enumeration lists the possible
30120 implementations of the Partition Communication Subsystem for the
30121 Distributed Systems Annex (DSA). The three available implementations
30122 are the dummy stub implementation (No_DSA), and two versions based on
30123 two different distribution runtime libraries: GARLIC and PolyORB. Both
30124 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30126 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30129 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30130 between the GARLIC and PolyORB versions of the distributed systems
30132 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30134 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30136 * gnat1drv.adb: Suppress calling the back end when
30137 Frontend_Layout_On_Target is true.
30139 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30141 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30142 Set_Read_Only): New subprograms.
30143 These new routines allow the user to set or unset the Owner execute
30144 and Owner write permission flags on a file.
30146 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30147 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30149 2004-10-26 Matthew Gingell <gingell@gnat.com>
30151 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30153 2004-10-26 Pascal Obry <obry@gnat.com>
30155 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30156 memory before the faulting page we properly test the process read
30157 access for this address using appropriate Win32 routine.
30158 (HPUX sections): guard with "__hpux__" instead of "hpux".
30160 2004-10-26 Robert Dewar <dewar@gnat.com>
30162 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30163 entry parameter if pragma Unreferenced set, since we do not properly
30164 handle the case of multiple parameters.
30166 2004-10-26 Vincent Celier <celier@gnat.com>
30168 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30169 (Ada_Objects_Path.Add): For a library project, add to the object path
30170 the library directory only if there is no object directory or if the
30171 library directory contains ALI files.
30172 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30174 2004-10-26 Vincent Celier <celier@gnat.com>
30176 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30177 extension of library projects.
30179 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30180 path defaults to ".:<prefix>/lib/gnat".
30181 (Parse): For an extending all project, allow direct import of a project
30182 that is virtually extended.
30184 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30185 the specified name is directly imported, return its ID. Otherwise, if
30186 an extension of this project is imported, return the ID of the
30189 2004-10-26 Robert Dewar <dewar@gnat.com>
30191 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30192 (Sub3): New procedure, used by Scaled_Divide
30193 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30194 correct more than one instance of failure to propagate carries
30196 (Double_Divide): Handle overflow case of largest negative number
30197 divided by minus one.
30199 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30200 the case of a quotient value out of range.
30203 2004-10-26 Robert Dewar <dewar@gnat.com>
30205 * s-bitops.adb (Bit_Eq): Remove redundant check.
30207 * s-bitops.ads: Minor comment updates
30208 Change some occurrences of Address to System.Address
30210 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30212 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30214 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30215 accessibility check to prefix that is a protected operation.
30217 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30219 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30220 empty, post message on stub.
30222 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30223 Javier Miranda <miranda@gnat.com>
30225 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30226 current instance appears within a unit that is directly in the context
30228 Used to determine whether the body of the instance should be analyzed
30229 immediately after its spec, to make its subprogram bodies available
30230 for front-end inlining.
30231 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30232 constraint is not allowed on the component type (AARM 12.5.3(3))
30234 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30236 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30237 'Storage_Pool): enhance, document & limit detection of non-sharable
30240 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30242 * s-pooglo.ads: Add more documentation now that this pool is properly
30245 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30247 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30248 or protected type with discriminants, do not constrain the
30249 corresponding record type if the subtype declaration has no
30250 discriminant constraints. This can be the case in source code, or in
30251 the subtype declaration created to rename an actual type within an
30254 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30256 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30257 different kind of stub (possibly wrong name for file), do not check
30259 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30260 includes call to some function that returns an unconstrained type, do
30263 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30265 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30266 appear in the code for the main unit. Dependencies among units in the
30267 context of the main unit are established when those other units are
30268 compiled. Otherwise spurious elaboration constraints can generate
30269 incorrect elaboration circularities.
30271 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30272 Ed Schonberg <schonberg@gnat.com>
30274 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30275 subprogram is called with a parameter that is not an object name. This
30276 situation arises for some cases of illegal code, which is diagnosed
30277 later, and in this case it is wrong to call Is_Aliased, as that might
30278 cause a compiler crash.
30279 (Explain_Limited_Type): Refine previous fix to include
30280 inherited components of derived types, to provide complete information.
30282 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30283 is the prival for a protected object.
30284 It is necessary to mark this entity as a variable, in addition to
30285 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30286 modified to avoid checking the Aliased flag on entities that are not
30287 objects. (Checking that flag for non-objects is erroneous and could
30288 lead to a compiler crash).
30290 2004-10-26 Robert Dewar <dewar@gnat.com>
30292 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30293 X_Frac = 0.5, then we know that the number X must be positive.
30294 (Succ): Remove the same redundant test, and also fix the primary test
30295 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30297 (Decompose): Add fuller comments to spec
30299 2004-10-26 Pascal Obry <obry@gnat.com>
30301 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30302 validity (process must have read access). Set to 0 in all other cases.
30303 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30304 violation on Win32.
30305 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30306 segmentation violation.
30308 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30310 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30311 whose type is a constructed subtype of an aliased object with an
30312 unconstrained nominal subtype, convert the actual to the constructed
30313 subtype before taking its address.
30315 2004-10-26 Vincent Celier <celier@gnat.com>
30317 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30318 (Is_Path_Name_Case_Sensitive): New function
30320 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30321 (Base_Name, Simple_Name, Current_Directory, Compose,
30322 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30325 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30326 Vasiliy Fofanov <fofanov@act-europe.fr>
30327 Vincent Celier <celier@gnat.com>
30329 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30330 "memory management issues" section and document some of the useful
30331 memory pools provided as part of the GNAT library.
30332 Remove "virtual" from declaration of A::method2 in
30333 the simple example of Ada/C++ mixed system.
30334 Library Projects may be virtually extended: their virtual extensions
30335 are not Library Projects.
30336 Added section on extending project hierarchies.
30338 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30340 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30342 (__gnat_portable_spawn): Remove const.
30344 * mingw32.h (MAXPATHLEN): Check for previous definition.
30346 2004-10-17 Matthias Klose <doko@debian.org>
30348 * gnatvsn.ads: Set gnat library version to 4.0.
30350 2004-10-05 Vincent Celier <celier@gnat.com>
30352 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30354 2004-10-04 Laurent Guerby <laurent@guerby.net>
30357 * Makefile.in: Define and use RANLIB_FLAGS.
30359 2004-10-04 Pascal Obry <obry@gnat.com>
30361 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30362 other x86 platforms).
30364 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30366 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30367 in general and triggers stack alignment adjustment for thread entry
30368 points on targets where this is necessary.
30370 2004-10-04 Bernard Banner <banner@gnat.com>
30373 * Makefile.in: Add section for powerpc linux
30374 Add variant i-vxwork-x86.ads
30376 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30378 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30380 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30381 table registration calls when need be. Ensures no reference to the crt
30382 ctors symbol are issued in the SJLJ case, which avoids possible
30383 undefined symbol errors in the case of modules to be statically linked
30386 2004-10-04 Javier Miranda <miranda@gnat.com>
30388 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30389 in-line the code corresponding to subprogram Analyze_Actuals. In
30390 addition, analyze the actuals only in case of subprogram call.
30392 2004-10-04 Ed Falis <falis@gnat.com>
30394 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30396 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30398 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30399 in the documentation.
30401 2004-10-04 Robert Dewar <dewar@gnat.com>
30403 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30405 (Analyze_Block_Statement): Add circuitry to detect following dead code
30406 (Check_Unreachable_Code): Handle case of block exit
30408 2004-10-04 Robert Dewar <dewar@gnat.com>
30410 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30411 (XMatchD): Avoid warning for Logic_Error call
30413 2004-10-04 Robert Dewar <dewar@gnat.com>
30415 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30416 consider expressions buried within a procedure actual to be an actual.
30417 This caused some blowups with uses of packed slices within a procedure
30420 2004-10-04 Robert Dewar <dewar@gnat.com>
30422 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30423 longer need to be initialized to zero.
30424 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30425 initialized to zero.
30427 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30428 considered valid, even if the representation is modular. That's correct
30429 now that we no longer initialize packed modular arrays to zero.
30431 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30432 suffixes. These are now documented as the only cases in which the
30433 debugger ignores outer records.
30434 Previously, the spec allowed arbitrary suffixes for this purpose.
30435 Change name of LJM to JM for packed array pad records
30436 Create separate section on packed array handling, and add a whole new
30437 set of comments to this section describing the situation with packed
30438 modular types and justification requirements depending on endianness.
30440 2004-10-04 Robert Dewar <dewar@gnat.com>
30442 * a-except.adb: Add a comment for last change
30444 * einfo.ads: Minor spelling correction in comment
30446 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30448 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30451 * sem_util.ads: Minor comment update
30453 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30455 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30456 Inline_Always when in Configurable_Run_Time mode.
30458 * sem_prag.adb (Process_Convention): If entity is an inherited
30459 subprogram, apply convention to parent subprogram if in same scope.
30460 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30461 when in Configurable_Run_Time mode.
30463 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30465 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30466 class_wide type after component list has been inherited.
30468 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30470 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30471 Denotes_Previous_Actual, to handle properly the case of a private
30472 actual that is also the component type of a subsequent array actual.
30473 The visibility status of the first actual is not affected when the
30474 second is installed.
30475 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30476 make fully recursive the treatment of formals of packages declared
30478 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30479 the above on exit from an instantiation.
30480 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30481 current instantiation which is now complete.
30482 (Analyze_Package_Instantiation): No instantiated body is needed if the
30483 main unit is generic. Efficient, and avoid anomalies when a instance
30484 appears in a package accessed through rtsfind.
30486 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30488 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30489 do not generate a declaration for a temporary if the call is part of a
30490 library-level instantiation.
30492 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30494 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30495 searching for a limited component to flag.
30497 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30498 expansion of Input, to account for the fact that the implicit call
30499 generated by the attribute reference must freeze the user-defined
30500 stream subprogram. This is only relevant to 'Input, because it can
30501 appear in an object declaration, prior to the body of the subprogram.
30503 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30504 expansion can proceed and further errors uncovered.
30505 (Minor clean up): Fix cases of using | instead of \ for continuation
30508 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30510 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30512 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30513 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30514 Use gcc_assert and gcc_unreachable.
30516 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30517 specified alignment before validating size.
30518 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30519 stripped-down declaration for the type of the inner field when making
30522 * utils.c (finish_record_type): Do not compute the size in units
30523 incrementally. Instead compute it once for the rep clause case.
30524 Use gcc_assert and gcc_unreachable.
30526 2004-10-04 Vincent Celier <celier@gnat.com>
30528 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30530 (Is_Valid_Path_Name): Take '/' as a directory separator.
30532 2004-10-04 Vincent Celier <celier@gnat.com>
30534 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30535 (Extended_Project) only if Extended_Project is defined, to avoid
30537 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30539 (Parse_Single_Project): Ditto.
30541 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30542 Add_To_Project_Path for virtual projects.
30544 2004-10-04 Vincent Celier <celier@gnat.com>
30546 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30548 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30549 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30550 parameter Options_2.
30552 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30553 Build_Dynamic_Library with an empty Options_2.
30555 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30558 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30559 directory separator, if any.
30560 (Gprmake): Do not allow mains on the command line for library projects.
30561 Do not attempt to link when the project is a library project.
30562 (Library_Opts): New table to store Library_Options.
30563 (Build_Library): If Library_Options is specified, pass these options
30564 when building a shared library.
30566 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30568 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30569 the end of this procedure now that the unlock operation was inserted
30572 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30574 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30575 corresponding to the Preallocated_Stacks flags in System.
30576 (Get_Target_Parameters): Including the processing for
30577 Preallocated_Stacks.
30579 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30580 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30583 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
30584 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
30585 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30586 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30587 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30588 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30589 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30590 used to signal whether the compiler creates the required stacks and
30591 descriptors for the different tasks (when True) or it is done by the
30592 underlying operating system at run time (when False).
30593 It is initially set to False in all targets.
30595 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30596 if it is supported by the target.
30597 (Make_Task_Create_Call): Pass the stack address if it has been
30598 previously created. Otherwise pass a Null_Address.
30600 * snames.adb: Add _stack.
30602 * snames.ads: Add Name_uStack. Required to allow the expander to
30603 statically allocated task stacks.
30605 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30606 Stack_Address argument.
30607 Check that its value is equal to Null_Address because this target does
30608 not support the static stack allocation.
30610 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30612 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30615 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30617 * exp_dist.adb: Split declaration of asynchronous flag out of
30618 Add_RACW_Read_Attribute.
30619 Minor reformatting for better alignment with PolyORB version.
30620 Store the entity for the asynchronous flag of an RACW, rather than the
30621 expression, in the asynchronous flags table. This will allow this flag
30622 to be used in other subprograms beside Add_RACW_Read_Attribute.
30624 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30626 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30627 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30628 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30629 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30630 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30631 sockets constant MSG_NOSIGNAL (Linux-specific).
30632 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30633 all Send operations.
30634 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30635 from trigerring SIGPIPE.
30636 Rename components to avoid clash with Ada 2005 possible reserved
30638 (Check_Selector): When the select system call returns with an error
30639 condition, propagate Socket_Error to the caller.
30641 2004-10-01 Jan Hubicka <jh@suse.cz>
30643 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30645 2004-09-23 Robert Dewar <dewar@gnat.com>
30648 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30649 instead do this at freeze time (we won't do it if there is an address
30651 Change "pragma inline" to "pragma Inline" in information and error
30653 Minor reformatting.
30655 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30656 right way of doing things after all.
30657 (Freeze_Entity): For object, set Is_Public for imported entities
30658 unless there is an address clause present.
30660 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30662 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30663 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30664 ensures proper handling of types with rep clauses, which might have
30665 their TYPE_SIZE set already.
30667 2004-09-21 Robert Dewar <dewar@gnat.com>
30669 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30670 packed array types in both little- and big-endian cases. This change
30671 ensures that we no longer count on the unused bits being initialized
30672 for such types (and in particular ensures that equality testing will
30673 only read the relevant bits).
30674 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30675 These changes mean that we no longer need to initialize small packed
30677 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30678 optimization to an LJM field as to its parent field.
30680 * ada-tree.h, trans.c, utils.c, utils2.c:
30681 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30683 2004-09-20 Jan Hubicka <jh@suse.cz>
30685 * utils.c (gnat_finalize): Remove.
30686 (end_subprog_body): Directly call cgraph_finalize_function;
30687 do not lower the nested functions.
30689 2004-09-20 Robert Dewar <dewar@gnat.com>
30692 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30693 if an address clause is present, since that means that the Import
30696 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30698 * 5tsystem.ads: Removed, no longer used.
30700 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30701 Zack Weinberg <zack@codesourcery.com>
30703 * ada-tree.def: Use tree_code_class enumeration constants
30704 instead of code letters.
30705 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30706 Update for new tree-class enumeration constants.
30708 2004-09-17 Vincent Celier <celier@gnat.com>
30710 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30711 capabilities of the general project manager.
30713 2004-09-09 Vincent Celier <celier@gnat.com>
30715 * a-direct.ads: Add pragma Ada_05
30716 (Directory_Entry_Type): Give default value to component Kind to avoid
30717 not initialized warnings.
30719 * a-direct.adb (Current_Directory): Remove directory separator at the
30721 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30722 an existing directory.
30723 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30724 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30725 Convert the result to File_Size.
30727 * prj.ads: (Project_Error): New exception
30729 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30730 Prj.Com, not from Osint.
30731 (Attrs, Package_Attributes): Tables moved to private part of spec
30732 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30734 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30735 Prj.Project_Error after call to Fail.
30736 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30737 Fail. Check that package name is not already in use.
30739 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30740 used by tools, not only by the project manager, and to indicate that
30741 exception Prj.Prj_Error may be raised in case of problem.
30742 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30744 (Attrs, Package_Attributes): Table instantiations moved from the body to
30745 the private part to be accessible from Prj.Attr.PM body.
30747 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30748 from new package Prj.Attr.PM.

30805 raise Program_Error if called from a protected operation.
30807 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30808 the protected action nesting level.
30809 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30810 protected action nesting level.
30811 (Unlock): When pragma Detect_Blocking is active decrease the protected
30812 action nesting level.
30814 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30815 Protected_Action_Nesting.
30817 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30818 Common_ATCB record. It contains the dynamic level of protected action
30819 nesting for each task. It is needed for checking whether potentially
30820 blocking operations are called from protected operations.
30821 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30822 Detect_Blocking is active or not in the partition.
30824 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30858 contains the required machinery for handling that.
30860 * sem_util.ads: Change comment associated to procedure
30861 Check_Potentially_Blocking_Operation.
30862 This procedure does not insert a call for raising the exception because
30863 that is currently done by the run time.
30865 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30867 * init.c: Add the global variable __gl_detect_blocking that indicates
30868 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30869 making the pragma available at run time.
30870 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30873 pragma Detect_Blocking is active.
30875 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30877 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30878 DB is found in the ali file. Any unit compiled with pragma
30879 Detect_Blocking active forces its effect in the whole partition.
30881 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30882 Detect_Blocking is active and delay is called from a protected
30885 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30886 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30887 Detect_Blocking is active (0 otherwise).
30888 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30889 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30899 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30900 Update API in placeholder implemetation of s-parint to reflect changes
30901 in distribution runtime library.
30903 * sem_ch3.adb (Expand_Derived_Record): Rename to
30904 Expand_Record_Extension.
30906 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30907 primitive operations of potentially distributed object types that have
30908 non-controlling anonymous access formals.
30910 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30912 New implementation of expansion for remote access-to-subprogram types,
30913 based on the RACW infrastructure.
30914 This version of sem_dist is compatible with PolyORB/DSA as well as
30917 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30918 Asynchrronous that applies to a remote access-to-subprogram type, mark
30919 the underlying RACW type as asynchronous.
30921 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30922 __gnat_using_gnu_linker to 1.

30932 Expand_Record_Extension.
30933 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30934 a component declaration must remain attached at that point in the
30935 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30936 It is therefore necessary to take a copy of the expression when building
30937 the corresponding assignment statement in the init proc.
30938 As a side effect, in the case of a derived record type, we now see the
30939 original expression, without any rewriting that could have occurred
30940 during expansion of the ancestor type's init proc, and we do not need
30941 to go back to Original_Node.
30943 * exp_ch3.ads (Expand_Derived_Record): Rename to
30944 Expand_Record_Extension.

30951 subprogram. The proxy object is used as the designated object
30952 for RAS values on the same partition (unless All_Calls_Remote applies).
30953 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30954 System.Partition_Interface.Get_Unique_Remote_Pointer.

30959 New implementation of expansion for remote access-to-subprogram types,
30960 based on the RACW infrastructure.
30962 * exp_dist.ads (Copy_Specification): Update comment to note that this
30963 function can copy the specification from either a subprogram
30964 specification or an access-to-subprogram type definition.
30966 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30968 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30969 in an instance, between an explicit subprogram an one inherited from a
30970 type derived from an actual.
30972 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30973 add a polling call if the subprogram is to be inlined by the back-end,
30974 to avoid repeated calls with multiple inlinings.
30976 * checks.adb (Apply_Alignment_Check): If the expression in the address
30977 clause is a call whose name is not a static entity (e.g. a dispatching
30978 call), treat as dynamic.

30982 * g-trasym.ads: Minor reformatting
30984 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

30993 2004-09-09 Pascal Obry <obry@gnat.com>
30995 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30996 enable map file generation. Add the right option to generate the map
30997 file if Map_File is set to True.
30999 * gnatdll.adb (Gen_Map_File): New variable.
31000 (Syntax): Add info about new -m (Map_File) option.

31028 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31029 of variable length temporaries for function return now that the
31030 back-end and gigi support it.

31081 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
31082 packed indexed component where array is an IN OUT formal. This
31083 generated garbage code previously.

31102 expander is not active (but check for unset reference to prefix of
31105 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31106 pragma Debug as an if statement with a constant condition, for
31107 consistent treatment of entity references contained within the
31108 enclosed procedure call.
31110 2004-09-01 Vincent Celier <celier@gnat.com>
31112 * bindgen.adb: (Set_EA_Last): New procedure
31113 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

31137 2004-09-01 Pascal Obry <obry@gnat.com>
31139 * gprcmd.adb (Extend): Do not output trailing directory separator. This

31142 (gprcmd): Idem for "pwd" internal command.
31144 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31145 target names rewrite to fix regressions with recent version of

31197 2004-08-16 Pascal Obry <obry@gnat.com>
31199 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31200 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31201 option and not mdll anymore. Update comment.
31203 2004-08-16 Pascal Obry <obry@gnat.com>
31205 * bld.adb (Put_Include_Project): Properly handle directory separators
31208 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31221 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31223 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31224 for a global aliased object with a variable size and an unconstrained
31225 nominal subtype, pretend there is no initializer if the one we have is
31226 incomplete, and avoid referencing an inexistant component in there. The
31227 part we have will be rebuilt anyway and the reference may confuse
31228 further operations.
31230 2004-08-13 Thomas Quinot <quinot@act-europe.fr>

33210 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33211 includes case of a variable referenced on the left hand side of an
33212 assignment, therefore remove redundant code. Variables and prefixes of

33214 hand side. Warnings are now properly emitted when variables or prefixes
33215 are assigned but not read.
33217 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33218 left hand side referenced variables. Private access types do not
33219 produce the warning "variable ... is assigned but never read".

33221 Aliased, renamed objects and access types do not produce the warning
33222 "variable ... is assigned but never read" since other entities may read
33223 the memory location.

33879 Merge from tree-ssa-20020619-branch.
33881 * config-lang.in (boot_language, build_by_default): Set
33883 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.

33918 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33919 Analyze on the library unit node after generation of distribution stub
33920 constructs. The call was a no-op because Unit_Node has already been
33921 Analyzed, and the tree fragments for the distribution stubs are
33922 analyzed as they are inserted in Exp_Dist.
33923 Update comment regarding to distribution stubs to reflect that we
33924 do not generate stub in separate files anymore.

33942 has been rewritten as an explicit dereference, retrieve type of
33943 original node to check for possibly unconstrained record type.
33945 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33947 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33948 overriding, use the operation of the parent unconditionally.
33950 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33951 operation when either operand is a literal, to avoid further
33954 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33955 overridden by a previous explicit declaration, mark the previous entity
33958 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33959 Is_Visibly_Controlled, to determine whether a declaration of a
33960 primitive control operation for a derived type overrides an inherited
33961 one. Add warning if the explicit declaration does not override.
33963 2004-05-10 Vincent Celier <celier@gnat.com>
33965 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33966 some cases when the sources are no longer present.
33968 * make.adb (Collect_Arguments): Fail if an external source, not part
33969 of any project need to be compiled, when switch -x has not been
33972 * makeusg.adb: Document new switch -x
33974 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33975 defaulted to False.
33977 * switch-m.adb (Scan_Make_Switches): New switch -x
33979 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33980 gnatmake switch -x.
33982 * gnat_ugn.texi: Document new gnatmake switch -x
33984 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
33986 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
33988 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
33989 (process_attributes): Likewise.
33991 2004-05-10 Joel Brobecker <brobecker@gnat.com>
33993 * s-inmaop.ads: Fix spelling mistake in one of the comments.
33995 2004-05-10 Robert Dewar <dewar@gnat.com>
33997 * gnat_ugn.texi: Document that for config pragma files, the maximum
33998 line length is always 32767.
34000 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34001 literals is now allowed.
34003 * gnat-style.texi: Remove statement about splitting long lines before
34004 an operator rather than after, since we do not follow this rule at all.
34005 Clarify rule (really lack of rule) for spaces around exponentiation
34007 * sem_elim.adb: Allow concatenation of string literals as well as a
34008 single string literal for pragma arguments.
34010 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34012 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34013 written for append case.
34015 * frontend.adb: Changes to avoid checking max line length in config
34018 * g-os_lib.ads: Minor reformatting
34020 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34021 wrong in any case. Instead use standard value. Noticed during code
34024 * opt.ads (Max_Line_Length): New field, used to implement removal of
34025 limitation on length of lines when scanning config pragma files.
34027 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34028 makeutl.ads, makeutl.adb: Minor reformatting
34030 * scn.adb: Do not check line length while scanning config pragma files

35219 as is done for non-private derived record types.
35221 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35222 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35223 candidate interpretation in an overloaded call.

35226 expression is Null and target type is not an access type (e.g. a

35237 complete assignment subtree which is now unnecessary, as the expansion
35238 of inlined call has been improved to preserve a consistent assignment
35239 tree. Note_Possible_Modification must be called only
35240 after checks have been applied, or else unnecessary checks will
35243 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35244 of explicit dereferences that do not Come_From_Source:

35246 pointer (an assignment to an implicit dereference must not be
35247 recorded as modifying the pointer);
35248 - do not rely on Original_Node being present (Analyze_Assignment
35249 calls Note_Possible_Modification on a copied tree).
35251 * sem_warn.adb (Check_References): When an unset reference to a pointer
35252 that is never assigned is encountered, prefer '<pointer> may be null'
35253 warning over '<pointer> is never assigned a value'.

35322 a string literal, create a temporary for it, constant folding only
35323 handles scalars here.

35516 information for protected (wrapper) operation as well, to simplify gdb
35519 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35562 a classwide type (for which Is_Object_Reference holds), but it can
35563 also be a value conversion for an access-to-classwide type. In the
35564 latter case, there is an implicit dereference, and the original node
35565 for the prefix does not verify Is_Object_Reference.

35651 gigi has enough information to construct the record, and there is no
35652 place in the tree for the declaration.
35654 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35655 serial number for the dummy body that is built for analysis, to avoid
35656 inconsistencies in the generation of internal names when compiling
35659 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35661 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35664 2004-03-22 GNAT Script <nobody@gnat.com>
35666 * Make-lang.in: Makefile automatically updated
35668 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35670 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35671 * trans.c (tree_transform, emit_index_check): Likewise.
35672 * utils.c (build_template): Likewise.
35673 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
35674 (maybe_unconstrained_array, unchecked_convert): Likewise.
35675 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.

35693 Minor reformatting.
35695 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35697 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35698 as regular exception objects and not as mere integers representing the
35699 condition code. The latter approach required some dynamics to mask off
35700 severity bits, which did not fit well into the GCC table based model.
35701 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35702 exception data objects. We don't it and it would conflict with the other
35703 external symbol we have to generate for such exceptions.
35705 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35706 the special code for VMS exceptions, since these are now represented
35707 as regular exceptions objects.
35709 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35711 * decl.c (debug_no_type_hash): Remove.

35715 2004-03-19 Laurent Guerby <laurent@guerby.net>
35717 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35718 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35720 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35722 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35723 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35724 (TYPE_RM_SIZE_INT): Directly use type.values.

35726 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35727 TYPE_VALUES, not TYPE_FIELDS.

35740 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35742 * adaint.c: Update comments.
35744 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35745 GNATLIB_SHARED for FreeBSD.
35747 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35749 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35750 When needed (stack checking) the stack size is retrieved
35751 from the VxWorks kernel.
35753 * Makefile.in: Flag -nostdinc is required when building the run time
35754 for avoiding looking for files in the base compiler.
35755 Add the VxWorks specific version of the package body for
35756 System.Stack_checking.Operations (5zstchop.adb).
35758 * Make-lang.in: Add the object file for
35759 System.Stack_Checking.Operations.

35767 checking from this package to package System.Stack_Checking.Operations.
35768 This way, stack checking operations are only linked in the final
35769 executable when using the -fstack-check flag.
35771 2004-03-18 Doug Rupp <rupp@gnat.com>
35773 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35783 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35784 the procedures Add_To_Path_File.
35785 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35786 making sure that each directory is present only once and, for object
35787 dirs, when a directory already present is added, the duplicate is
35788 removed and the directory is always put as the last in the table.
35789 Write the path files at the end of these accumulations.
35791 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35792 Files_Htable for all sources.
35794 * prj-proc.adb (Process): Remove restrictions between not directly
35795 related extending projects.

35803 parameter Trusted_Mode.
35805 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35807 * scn.adb (Determine_License): Take into account a degenerated case
35808 when the source contains only comments.
35810 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35812 * sem_warn.adb (Check_References): For a warning on a selected
35813 component that does not come from source, locate an uninitialized
35814 component of the record type to produce a more precise error message.
35816 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35818 * 3zsoccon.ads: Fix multicast options.
35820 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35823 2004-03-15 Robert Dewar <dewar@gnat.com>

35826 pragma used for a private type.
35828 * lib-xref.adb (Generate_Reference): Do not generate warning if
35829 reference is in a different unit from the pragma Unreferenced.
35831 * 5vtpopde.adb: Minor reformatting
35832 Fix casing of To_Task_ID
35834 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35835 flag if we have an unchecked conversion to an access type in the same
35838 2004-03-15 Geert Bosch <bosch@gnat.com>
35840 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35841 imaginary parts, use Double precision throughout.
35843 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35844 we want to be able to compile run-time with -gnata for testing, but
35845 this may also be instantiated in user code that is compiled with -gnata.
35847 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35849 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

35851 throughout the various run-time units.
35852 (Exception_Data): Use Exception_Code for Import_Code.
35854 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35862 component, now reflected by an exported accessor.
35863 (is_handled_by): New routine to compute whether the propagated
35864 occurrence matches some handler choice specification. Extracted out of
35865 get_action_description_for, and expanded to take care of the VMS
35867 (get_action_description_for): Use is_handled_by instead of an explicit
35868 complex condition to decide if the current choice at hand catches the
35869 propagated occurrence.
35871 * raise.h (Exception_Code): New type for C.
35873 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35874 System.Standard_Library.Exception_Code, to allow references from the
35875 pragma import/export expander.
35877 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35878 New accessors to allow easy access to GNAT exception data
35880 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35881 redundant Handled_By_Others component, helper for the personality
35882 routine which will now be able to call the appropriate exception data
35885 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35886 component of Standard_Exception_Type to be the closest possible to
35887 Exception_Code in System.Standard_Library, that we cannot get at this
35888 point. Expand a ??? comment to notify that this type node should
35889 probably be rewritten later on.
35891 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35892 registration call to include a pointer to the exception object in the
35895 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35896 instead of int and explicit bitmasks.
35898 2004-03-15 Vincent Celier <celier@gnat.com>
35900 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35901 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35903 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35904 longer needed now that it is in the spec of
35905 System.Tasking.Task_Attributes.
35907 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35909 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35911 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35913 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35914 taken care of in Scan_Make_Arg.
35915 (Scan_Make_Arg): Add the executable suffix only if the argument
35916 following -o, in canonical case, does not end with the executable
35917 suffix. When in verbose mode and executable file name does not end
35918 with executable suffix, output the executable name, in canonical case.
35920 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35921 to avoid warnings when instantiating Ada.Task_Attributes.
35924 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35925 in the correct order.
35927 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35935 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35937 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35938 tagged type is inherited, and the parent operation is not frozen yet,
35939 force generation of a freeze node for the inherited operation, so the
35940 corresponding dispatch entry is properly initialized.
35941 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35942 when looking for user-defined equality operation.
35944 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35945 boolean when locating primitive equality of tagged component.
35947 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35949 a temporary before expanding assignment into a loop.
35951 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35952 priority in full, to ensure that any expanded subepxressions of it are
35953 elaborated in the scope of the init_proc.

35956 after object declaration, skipping over code that may have been
35957 generated for validity checks.
35959 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35960 discriminants, ignore the known discriminants of its full view, if
35961 any, to check legality.
35963 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35964 component if type has unknown discriminants.
35965 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35966 null if type has unknown discriminants.
35968 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35969 for end label when present.
35971 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35972 temporary file, rather than an empty string.
35974 2004-03-15 Ed Falis <falis@gnat.com>
35976 * s-thread.adb: Removed, no longer used.
35978 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

35998 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35999 Insert_Dereference_Action when rewriting an implicit dereference into
36000 an explicit one, this will be taken care of during expansion of the
36001 explicit dereference.
36002 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36003 of non-packed slices, since the dereference action generated by
36004 expansion of the explicit dereference is needed in any case.
36005 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36006 analyze and resolve the rewritten explicit dereference so it is seen
36008 (Insert_Dereference_Action): This procedure is now called only for the
36009 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36010 dereferences that do not come from source (including explicit
36011 dereferences resulting from rewriting implicit ones), but do not
36012 recursively insert a check for the dereference nodes contained within
36014 (Insert_Dereference_Action): Clarify and correct comment.

36891 checks for bitfield creation are triggered.
36892 (finish_record_type): During last pass over the fields, clear
36893 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37280 be modified by the binder generated main program if the -D switch is
37283 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37284 imported functions (since now we expect this to be done for imported
37287 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37288 Minor reformatting throughout
37290 * 5zinit.adb: Minor reformatting

37294 doing reformatting)
37296 * sprint.adb: Minor updates to avoid -gnatwa warnings
37298 * s-secsta.ads, s-secsta.adb:
37299 (SS_Get_Max): New function to obtain high water mark for ss stack
37300 Default_Secondary_Stack is not a constant since it may be modified by
37301 the binder generated main program if the -D switch is used.
37303 * switch-b.adb: New -Dnnn switch for binder
37306 Make -gnatg imply all warnings currently in -gnatwa

37337 Acquire new SS indication of secondary stack use from ali files
37339 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37340 (since now we expect this to be done for imported functions)
37342 * bindgen.adb: Generate call to modify default secondary stack size if
37345 * bindusg.adb: Add line for new -D switch
37347 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37348 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37349 Add circuitry for both records and arrays to avoid gigi
37350 processing if the type involved has non-bit-aligned components
37352 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37353 N_String_Literal node always references an E_String_Literal_Subtype
37354 entity. This may not be true in the future.
37355 (Possible_Bit_Aligned_Component): Move processing of
37356 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37358 * exp_ch6.adb (Expand_Thread_Body): Pick up
37359 Default_Secondary_Stack_Size as variable so that we get value modified
37360 by possible -Dnnn binder parameter.
37362 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37363 (Type_May_Have_Bit_Aligned_Components): New function.
37365 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37375 unless explicit Pure_Function pragma given, to avoid insidious bug of
37376 call to non-pure imported function getting eliminated.

37398 * rtsfind.adb (Load_Fail): Give full error message in configurable
37399 run-time mode if all_errors mode is set. This was not done in the case
37400 of a file not found, which was an oversight.
37401 Note if secondary stack unit is used by compiler.
37403 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37404 ineffective elaborate all pragmas on non-visible packages (this
37405 happened when a renamed subprogram was called). Now the elaborate all
37406 always goes on the package containing the renaming rather than the one
37407 containing the renamed subprogram.
37409 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37410 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37412 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37413 has an Etype that references an E_String_Literal.
37414 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37415 always references an E_String_Literal_Subtype entity. This may not
37416 be true in the future.
37418 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37421 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37424 2004-01-05 Ed Falis <falis@gnat.com>

37431 * bld.adb: Minor comment updates
37432 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37435 * make.adb (Gnatmake): Special process for files to compile/check when
37436 -B is specified. Fail when there are only foreign mains in attribute
37437 Main of the project file and -B is not specified. Do not skip bind/link
37438 steps when -B is specified.
37440 * makeusg.adb: Document new switch -B

37463 -gnatwa warning on static condition.
37465 2004-01-05 Doug Rupp <rupp@gnat.com>

37469 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37471 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37472 all attributes, including read-only attribute.
37474 2004-01-05 Pascal Obry <obry@gnat.com>

37477 library naming scheme.
37479 * mlib-prj.adb (Build_Library): Generate different names for the static
37480 or dynamic version of the GNAT runtime. This is needed to support the
37481 new shared library naming scheme.

37483 based on the new naming scheme.
37485 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37486 scheme for the shared runtime libraries.
37489 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37491 (install-gnatlib): Do not create symlinks for shared libraries.
37492 (gnatlib-shared-default): Idem.
37493 (gnatlib-shared-dual-win32): New target. Not used for now as the
37494 auto-import feature does not support arrays/records.
37495 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37496 (gnatlib-shared-vms): Fix shared runtime libraries names.
37498 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37499 dependent runtime shared library name.
37501 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37503 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37506 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37508 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37509 protected objects when allocator has a subtype indication, not a
37510 qualified expression. Note that qualified expressions may have to be
37511 checked when limited aggregates are implemented.
37513 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37514 pure, emit warning.
37515 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37516 subprogram is imported, remove warning.
37518 2004-01-05 Geert Bosch <bosch@gnat.com>
37520 * s-poosiz.adb: Update copyright notice.
37521 (Allocate): Use Task_Lock to protect against concurrent access.
37522 (Deallocate): Likewise.

37560 * cstand.adb (Create_Standard): Change the way how the declaration of
37561 the Duration type is created (making it the same way as it is for all
37562 the other standard types).
37564 2003-12-17 Robert Dewar <dewar@gnat.com>
37566 * s-crtl.ads: Fix header format
37567 Change Pure to Preelaborate

37572 the expression type only if it is declared in the current unit.
37574 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37575 are universal and already analyzed, as can occur in constrained
37576 subcomponents that depend on discriminants, when one constraint is a
37579 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37580 type Any_Fixed is legal as the argument of a conversion, if only one
37581 fixed-point type is in context.

37594 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37595 (Gnatchop): Do not set failure status when reporting the number of
37598 2003-12-15 Doug Rupp <rupp@gnat.com>
37600 * s-ctrl.ads: New file.

37620 * Make-lang.in: Makefile automatically updated
37622 2003-12-11 Ed Falis <falis@gnat.com>
37624 * 5zinit.adb: Clean up.
37626 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37627 to __gnat_map_signal, imported from init.c to support
37628 signal -> exception mappings that depend on the vxWorks version.
37631 Created and exported __gnat_map_signal to support signal -> exception
37632 mapping that is dependent on the VxWorks version.

37660 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37661 Minor reformatting throughout
37663 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37665 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37666 bounds of a loop, create a separate block in order to generate proper
37667 cleanup actions to prevent memory leaks.
37669 * sem_res.adb (Resolve_Call): After a call to
37670 Establish_Transient_Scope, the call may be rewritten and relocated, in
37671 which case no further processing is needed.
37673 * sem_util.adb: (Wrong_Type): Refine previous fix.
37674 Fixes ACATS regressions.
37677 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37680 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37682 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37683 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37686 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37689 2003-12-08 Robert Dewar <dewar@gnat.com>
37691 * 7sintman.adb: Minor reformatting
37693 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37694 standard linker options to get standard libraries linked. We now plan
37695 to provide dummy versions of these libraries to match the appropriate
37696 configurable run-time (e.g. if a library is not needed at all, provide
37697 a dummy empty library).
37699 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37700 options (-L parameters and standard libraries). What we plan to do is
37701 to provide dummy libraries where the libraries are not required.
37703 * gnatbind.adb: Minor comment improvement
37705 2003-12-08 Javier Miranda <miranda@gnat.com>
37707 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37708 aggregate in the parent. Otherwise constants with limited aggregates
37709 are not supported. Add new formal to pass the component type (Ctype).
37710 It is required to call the corresponding IP subprogram in case of
37711 default initialized components.
37712 (Gen_Assign): In case of default-initialized component, generate a
37713 call to the IP subprogram associated with the component.
37714 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37715 of aggregate with default initialized components.
37716 (Has_Default_Init_Comps): Improve implementation to recursively check
37717 all the present expressions.
37719 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37720 to indicate that the initialization call corresponds to a
37721 default-initialized component of an aggregate.
37722 In case of default initialized aggregate with tasks this parameter is
37723 used to generate a null string (this is just a workaround that must be
37724 improved later). In case of discriminants, this parameter is used to
37725 generate a selected component node that gives access to the discriminant
37728 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37729 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37730 allocated aggregates with default-initialized components.
37732 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37733 the box notation is used in positional aggregates.

37749 * prj-part.adb (With_Record): New component Node
37750 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37751 Set the scanner to return ends of line and comments as tokens, if
37752 Store_Comments is True.
37753 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37754 comments are associated with these nodes. Store the node IDs in the
37756 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37758 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37759 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37760 current project. Call Tree.Restore afterwards. Set the various nodes
37761 for comment storage (Next_End, End_Of_Line, Previous_Line,
37764 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37765 defaulted to False.
37767 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37768 to False. When Truncated is True, truncate the string, never go to the
37770 (Write_End_Of_Line_Comment): New procedure
37771 (Print): Process comments for nodes N_With_Clause,

39514 a subunit is missing.
39515 (Instantiate_Subprogram_Body): If body of function is missing, set type
39516 of return expression explicitly in dummy body, to prevent cascaded
39517 errors when a subunit is missing.
39521 (Access_Subprogram_Declaration): Verify that return type is valid.
39525 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39530 (Corresponding_Discriminant): If the scope of the discriminant is a
39531 private type without discriminant, use its full view.

41556 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41557 function approach did not work well because of a side effect (the
41558 function call could reallocate the table which was being indexed
41559 using its result). Fixes ada/4851.

41837 When using a project file, fail if specified executable is relative
41838 path with directory information, and prepend executable, if not

41926 2001-12-17 Laurent Pautet <pautet@gnat.com>
41929 Fix comment of Shutdown_Socket and Close_Socket. These functions
41930 should not fail silently because if they are called twice, this
41931 probably means that there is a race condition in the user program.
41932 Anyway, this behaviour is consistent with the rest of this unit.
41933 When an error occurs, an exception is raised with the error message
41934 as exception message.

43268 instead of the previous simple checksum algorithm.
43269 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43270 (Set_Source_Table): idem.
43273 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43274 instead of simple checksum.
43275 (CRC_Match): new function.
43276 (CRC_Error): new constant.
43278 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43279 a CRC now and not a simple checksum. A CRC uses lower-case hex
43280 letters, fixes ambiguity in parsing.
43282 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43283 is what this variable will store.
43285 * bcheck.adb: Change reference to chechsum in comments by CRC.
43286 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43287 rename All_Checksum_Match to All_CRC_Match. Change due to API
43288 renaming since now GNAT does not use a simple checksum but a
43289 CRC using GNAT.CRC32.
43291 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43292 now and not anymore a simple checksum.

43329 Update comments for the CRC.
43331 * types.adb (Hex): Use lowercase for the letter part.
43333 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43334 for a word. This is currently used only for CRC. In previous version,
43335 the checksum was using a representation with all letter being
43336 upper-case. With the new implementation (using CRC) we do not remove
43337 the 32th bit of the CRC, so we can have an upper-case starting letter
43338 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43339 It is ambigous since the CRC was optional and could be followed by
43340 options like EB, EE. So now this routines uses lower-case letter for
43341 the hexadecimal representation. Strange enough only lower case letters
43342 where checked in Scan_ALI (even if this was not a possible case).
43344 * gnatvsn.ads (Library_Version): changed to 3.15a.
43346 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43349 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

43353 Add 2001 to copyright notice
43354 (Accumulate_Checksum): Modify to use System.CRC32.
43356 * ali-util.ads: Redo changes of previous revision to continue to use
43357 the word Checksum. Add 2001 to copyright notice.
