2033 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2034 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2035 N_Identifier. This was interfering with other cases that are rewritten

4129 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4130 convention from its base type, do not set the type to that of integer,
4131 because it may inherit a size clause.

4195 the visible part of the spec of a remote types unit.

4197 New local subprogram Is_Valid_Remote_Object_Type, replaces
4198 Is_Recursively_Limited_Private.
4199 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4200 non-controlling formals (and the return type, even though this is not
4201 explicit in the standard) must support external streaming.

4203 as above for of RAS types and RCI subprograms. (The return type is not

4208 * sem_util.ads, sem_util.adb
4209 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4210 Is_Remote_Call_Interface to identify RACW types in a stable and
4211 consistent way. We used to rely in this predicate on the privateness of
4212 the designated type and its ancestors, but depending on the currently
4213 visible private parts, this caused false negatives. We now uniformly
4214 rely on checks made at the point where the RACW type is declared.

4228 Add missing escaping of all-caps word 'CPP' in error messages.
4229 (Build_Discriminated_Subtype): Do not inherit representation clauses
4230 from parent type if subtype already carries them, because they are
4231 inherited earlier during derivation and already include those that may
4232 come from a partial view.
4234 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4235 Check the declarations of a subprogram body for proper deferred

4269 (Add_One_Interp): Ignore any interpretation that is a primitive
4270 operation of an RACW stub type (these primitives are only executed
4271 through dispatching, never through static calls).
4272 (Collect_Interps): When only one interpretation has been found, set N's
4273 Entity and Etype to that interpretation, otherwise Entity and Etype may
4274 still refer to an interpretation that was ignored by Add_One_Interp,
4275 in which case would end up with being marked as not overloaded but with
4276 an Entity attribute not pointing to its (unique) correct interpretation.
4278 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4281 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4291 (Print_Itype): Do not modify the sloc of the component type of a
4292 (packed) array itype, because it is an unrelated type whose source
4293 location is independent of the point of creation of the itype itself.

4335 equivalent representation, but has the advantage of allowing
4336 compilation of this file under 64 bits platforms.

8535 subprogram body that acts as its own spec may not have a non-private
8536 WITH clause on a private sibling.
8537 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8538 child unit is a renaming, create an implicit with_clause on that

8641 perform subtype conformance between the formals of the current entry
8642 and those of the target interface primitive.
8643 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8644 Timed_Entry_Call): Analyze the triggering statement as the first step of
8645 the processing. If this is a dispatching select, postpone the analysis
8646 of all select statements until the Expander transforms the select. This

8648 replicated some of the select statements. In case the Expander is
8649 disabled, perform regular analysis.
8650 (Check_Triggering_Statement): New routine.
8651 (Analyze_Requeue): Exclude any interpretations that are not entries when
8652 checking overloaded names in a requeue. Also test type conformance for
8653 matching interpretations rather than requiring subtype conformance at

8661 for the defaulted actual.
8663 2007-12-13 Geert Bosch <bosch@adacore.com>
8665 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9248 multiple inherited interfaces info. This information cannot be stored
9249 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9266 additional management on these nodes in Expand_Interface_Actuals.
9268 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9269 that handles use of 'Access and 'Unchecked_Access applied to

9315 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9316 used by VxWorks targets to have access to task-specific data and be
9317 able to extract the stack boundaries for stack checking.

9361 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9362 association for an access component, add an association with null as
9363 the expression. Remove testing for array subtypes and the setting in
9364 that case of Ctyp to the array component type, which prevented proper
9365 inclusion of an association for null-initialized arrays. Collapse
9366 condition that tests for array subtypes into just a test of
9367 Is_Partially_Initialized_Type (which already covers arrays anyway).

9384 * sem_ch4.adb: Minor code and comment reformatting.
9385 (Analyze_Allocator): When the designated type of an unconstrained
9386 allocator is a record with unknown discriminants or an array with

9521 type of file_info_ptr parameter.
9522 If mapped location support is enabled, create the isomorphic mapping
9523 between source files and line maps.

9553 Add a section on leap seconds control along with two entities used to
9554 enable and disable leap seconds support. The array Leap_Second_Times is
9555 now constant and contains hard time values pre-generated. Remove
9556 all elaboration code used to populate the table of leap seconds.

9616 2007-09-26 Javier Miranda <miranda@adacore.com>
9617 Eric Botcazou <ebotcazou@adacore.com>
9620 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9621 indirection added to the HT_Link component of the TSD. This is required
9622 to statically allocate the TSD.
9625 Minor reordering of the declarations in the private part. Required to
9626 add a level of indirection to the contents of the TSD component HT_Link.
9627 This is required to statically allocate the TSD.
9629 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9630 Is_Statically_Allocated set from constant objects.
9631 Do not make exported constants created by the compiler volatile.
9632 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9635 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9636 before returning them.
9638 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9639 public part of the package.
9640 (Make_DT): Move HT_Link component out of the TSD record. For this
9641 purpose Make_DT now declares a separate object that stores the
9642 HT_Link value, and initializes the TSD component with the address
9643 of this new object. The addition of this level of indirection is
9644 required to statically allocate the TSD because the TSD cannot
9645 have variable components.
9646 (Expand_Interface_Conversion): Improve the expanded code.
9647 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9649 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9650 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9651 if we are building static dispatch tables then we must not generate
9652 extra code to register the primitive because the dispatch table will
9653 be built at the end of the library package; otherwise we notify that
9654 we cannot build the static dispatch table.
9656 2007-09-26 Robert Dewar <dewar@adacore.com>
9658 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9673 for thunks associated with interface types.
9675 * einfo.ads: Improve documentatation of Is_Internal
9676 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9677 associated with interface types.
9678 Extensive comment fixes regarding flags that appear in all entities. The
9679 documentation is now consistent for all such flags (there were a number
9680 of errors in the documentation in this regard).
9682 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9684 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9685 of these procedures are passed a function call that already has
9686 build-in-place actuals (testing new flag
9687 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9688 the case where processing continues.
9689 (Expand_Call): If the call is generated from a thunk body then we
9690 propagate the extra actuals associated with the accessibility
9691 level of the access type actuals.
9693 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9694 of each extra formal of a protected operation to reference the
9695 corresponding extra formal of the subprogram denoted by the
9696 operation's Protected_Body_Subprogram.
9698 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9699 N_Function_Call nodes.
9701 2007-09-26 Robert Dewar <dewar@adacore.com>
9703 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9705 * debug.adb: Add d.s flag.

9709 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9710 debug variable so that it won't be initialized when pragma
9711 Initialize_Scalars is in effect.
9713 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9715 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9716 initialization of a full view. This is moved to
9717 Analyze_Package_Specification.
9719 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9720 preelaborable initialization of a full view in entity loop.
9721 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9722 its child units are use-visible only if they are visible child units.
9724 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9725 whether an expression can be used within a type declaration that
9726 requires preelaborable init.
9727 (Check_Components): Replace inline code that does partial checking for
9728 preelaborable default expressions with call to
9729 Is_Preelaborable_Expression.
9730 (Has_Preelaborable_Initialization): In the case of a generic actual
9731 subtype, (that is, Is_Generic_Actual is True), return the result of
9732 applying Has_Preelaborable_Initialization to the generic actual's base
9735 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9737 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9738 call to Jan_1_Day _Of_Week to optimize its performance.
9739 (Is_Leap): Move the routine to the scope of Week_In_Year.
9740 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9741 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9742 avoids calling Time_Of and Split, thus making it more efficent.
9743 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9745 * g-calend.ads (Week_In_Year): Change comment to reflect new
9748 2007-09-26 Emmanuel Briot <briot@adacore.com>
9750 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9751 Command_Line): New types
9752 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9753 support for defining how switches can be grouped on a command line (as
9754 is the case for -gnatw... for GNAT), and how simple switches can be
9755 used as aliases for more complex switches (-gnatwa is same as
9757 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9758 (Start, Current_*): New subprograms
9759 Added support for parsing an array of strings in addition to the real
9761 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9762 be moved from the body to the private part of the spec.
9763 (*): All subprograms now have an extra parameter with default value to
9764 specify which parser should be used. For backward compatibility, it
9765 defaults to parsing the command line of the application. They were also
9766 modified to properly handle cases where each of the argument does not
9767 start at index 1 (which is always true for Ada.Command_Line, but not
9768 when processing any Argument_List).
9769 (Free): New subprogram
9770 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9771 Argument): New subprograms
9772 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9773 special characters like ':', '=',... are now handled in a single place,
9774 which makes the code more extensible eventually.
9775 (Getopt, Full_Switch): When the switch was returned as part of the
9776 special character '*', make sure it is prepended by the switch character
9777 ('-' in general), so that the application knows whether "foo" or "-foo"
9778 was specified on the command line.
9780 2007-09-26 Florian Villoing <villoing@adacore.com>
9782 * g-dirope.adb (Remove_Dir): In case we are removing directories
9783 recursively, make sure that if an exception is raised during the
9784 processing, the current working directory is reset to its initial
9785 value before propagating the exception.
9787 2007-09-26 Vincent Celier <celier@adacore.com>
9789 * gnatbind.adb: If there are several ALI files specified and there is
9790 a main program to bind, the first ALI is expected to contain the main
9791 subprogram and the names of the binder generated files will be derived
9792 from the first ALI file name.
9793 (Gnatbind): Fix insertion character in invocation of Error_Msg
9795 2007-09-26 Vincent Celier <celier@adacore.com>
9797 * gnatcmd.adb (Check_Files): Do not include sources that have been
9798 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9800 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9802 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9803 information about each of its index types, following the type
9804 reference for its component type.
9806 2007-09-26 Vincent Celier <celier@adacore.com>
9808 * make.adb: (Kill): New procedure (__gnat_kill imported)

9819 2007-09-26 Vincent Celier <celier@adacore.com>
9821 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9823 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9824 Replace components Compiler_Min_Options and Binder_Min_Options with
9825 Compiler_Required_Switches and Binder_Required_Switches in record
9827 Remove components Default_Language and Config in Project_Tree_Data,
9830 * prj-attr.adb: New attributes Required_Switches (<language>) in
9831 packages Compiler and Binder.

9868 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9870 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9871 ancestor of the derived type, the operations are inherited from the
9872 primary dispatch table of the parent.
9873 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9874 when the context is an explicit type conversion.
9876 2007-09-26 Ed Schonberg <schonberg@adacore.com>

9921 no sources, but is an extending project.
9923 2007-09-25 Eric Botcazou <ebotcazou@adacore.com>
9925 * trans.c: Fix misplaced #define.

10176 potentially be called.
10177 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10178 body for 'Output when the type is abstract (only the creation of the
10179 body for 'Input is excluded when the type is abstract).

10181 statement, so that False will be returned for TTS_Stream_Input if the
10182 associated tagged type is an abstract extension. Add comments for
10184 (Expand_N_Object_Declaration): For the case of a shared passive
10185 variable, insert init proc call only after the shared variable
10186 procedures have been processed, because the IP call needs to undergo
10187 shared passive variable reference expansion, which requires these

10200 type, retrieve its value from the aggregate itself, where it must have
10203 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10204 to remove other spurious ambiguities on arithmetic operations involving
10205 literals and addresses, on systems where Address is a visible integer
10206 type, when the operator is called in functional notation.
10207 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10208 is legal when the types match, even if the operation is currently
10211 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10213 * sem_ch12.adb (Build_Local_Package): A formal package with no

10326 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10328 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10334 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10335 spurious ambiguities when integer literals appear in the context of an
10336 address type that is a visible integer type.
10338 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10339 exceptions never being raised.
10340 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10343 2007-08-31 Javier Miranda <miranda@adacore.com>
10345 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise

10356 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10357 library-level package renaming, pass the declaration associated with
10358 the renaming's special debug variable to Qualify_Entity_Names to ensure
10359 that its encoded name is properly qualified.
10361 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10362 occurring in the list of entities to qualify, and do not attempt to
10363 traverse an entity list in that case. Variables associated with
10364 ` library-level package renamings can now occur in the table.
10366 * exp_dbug.ads: Revise documentation of the encoding for renaming

10372 access type points to an unconstrained array.
10374 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10376 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10379 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect

10388 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10389 concatenations of string literals into a single literal, in order to
10390 avoid very deep recursion in the front end, which was causing stack
10393 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10394 string, and the right operand is a string literal (the case of "" &
10395 "..."), optimize by avoiding copying the right operand -- just use the
10396 value of the right operand directly.
10398 * stringt.adb (Store_String_Chars): Optimize by growing the
10399 String_Chars table all at once, rather than appending characters one by
10401 (Write_String_Table_Entry): If the string to be printed is very long,
10402 just print the first few characters, followed by the length. Otherwise,
10403 doing "pn(n)" in the debugger can take an extremely long time.
10405 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10406 Store_String_Char with Store_String_Chars.

10419 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10420 clauses of subunits, ignore limited_with_clauses that are illegal and
10421 have not been fully analyzed.
10423 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10425 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10426 flag, for effiency. It is called when analyzing arithmetic operators
10427 and also for actuals in calls that are universal_integers. The flag is
10428 set for the predefined type address, and for any type or subtype
10431 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10432 Universal_Integer, when the formal is a descendent of address and the
10433 call appears in user code.
10434 (Analyze_Selected_Component): if the prefix is a private extension, the
10435 tag component is visible.

10500 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10501 associated with Standard_Debug_Renaming_Type, to be used as the type of
10502 the special variables whose names provide debugger encodings for
10503 renaming declarations.
10505 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10506 (Set_Debug_Renaming_Link): Change to set Node25.

10513 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10514 and literal with creation of a variable of type
10515 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10516 and the entity of the renaming declaration.
10517 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10518 part of the name of a variable that has a Debug_Renaming_Link.
10520 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

10525 Ed Schonberg <schonberg@adacore.com>
10526 Javier Miranda <miranda@adacore.com>
10528 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10529 ancestor part given by an aggregate to test for an unchecked conversion,
10530 since this can occur in some cases when the ancestor part is a function
10531 call, and we don't want to fall into the recursive call to this
10532 procedure in that case.
10534 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10535 stream attributes on limited types to account for user-specified
10536 attributes as well as whether Input (resp. Output) becomes available
10537 due to Read (resp. Write) being available for the type. Change Boolean
10538 variable to the more accurate name
10539 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10540 double-"not" predicate at beginning of return statement to more
10541 understandable form.
10543 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10544 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10545 in a block statement and use that as the first statement of the
10546 expanded return rather than incorrectly using the handled sequence as
10547 the first statement.
10549 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10550 operation, generate an explicit freeze node for it rather than
10551 generating extra formals, to ensure that gigi has the proper order of
10552 elaboration for anonymous subtypes in the signature of the subprograms.
10553 (Build_In_Place_Formal): Move assertion to beginning of loop.
10554 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10557 applied to a function call (occurs for some cases of 'Input).
10559 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10560 2005, generate an extended return statement enclosing the result object
10563 * freeze.adb (Freeze_Record_Type): Extend the current management of
10564 components that are access type with an allocator as default value: add
10565 missing support to the use of qualified expressions of the
10566 allocator (which also cause freezing of the designated type!)
10567 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10568 dispatching operation, since extra formals may be needed by calls to
10569 build-in-place functions (such as stream 'Input).
10571 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10572 formals for 'Constrained and accessibility level in the case of a
10573 predefined dispatching operation.
10575 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10576 point, no need to find the parent node.
10578 2007-08-16 Javier Miranda <miranda@adacore.com>
10580 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10581 and entry barriers.
10583 2007-08-16 Javier Miranda <miranda@adacore.com>
10585 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10586 is not really required and can introduce regression with the debugger.
10587 The original problem is fixed with the patch written for checks.adb.
10589 2007-08-16 Thomas Quinot <quinot@adacore.com>
10591 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10601 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10602 parameter Including_Non_Switch, defaulted to True. When
10603 Including_Non_Switch is False, options that are not switches and
10604 appear as relative path are not converted to absolute paths.
10606 2007-08-16 Nicolas Roche <roche@adacore.com>
10608 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10619 from the immediate ancestor of Main_Unit_Entity.
10620 (Install_Limited_Withed_Unit): Do not install the limited view of
10621 package P if P is reachable through an ancestor chain from package C
10622 and C also has a with clause for P in its body.
10623 (Has_Limited_With_Clause): New routine.
10624 (Has_With_Clause): New routine.
10626 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10628 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10629 generic for an enclosing instance is a global reference, even though
10630 its scope is the enclosing instance.
10632 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10633 Javier Miranda <miranda@adacore.com>
10635 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10636 initialize a limited object.

10641 2007-08-16 Robert Dewar <dewar@adacore.com>
10643 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10646 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10648 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10649 implements an operation inherited from a progenitor interface, verify
10650 that they are subtype-conformant.
10652 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10653 Bob Duff <duff@adacore.com>
10654 Nicolas Setton <setton@adacore.com>
10656 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10657 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10658 the statement which is being resolved comes from a predefined library
10659 unit, all non-predefined library interpretations are skipped.
10660 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10661 but the "&" is user defined, give an error, because the folding would
10664 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10665 the parser has folded a long sequence of concatenations of string
10668 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10669 and "JMP_BUF" variables as artificial.
10670 (N_String_Literal): Do not use alloca for very long string literals. Use
10671 xmalloc/free instead. Otherwise the stack might overflow.

10718 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10719 Suppress unmodified in-out parameter warning in some cases
10720 This patch is a also fairly significant change to the way suppressible
10721 checks are handled.
10723 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10724 needed for access to concurrent record types generated by the expander.
10725 (Generate_Range_Check): When generating a temporary to capture the
10726 value of a conversion that requires a range check, set the type of the
10727 temporary before rewriting the node, so that the type is always
10728 properly placed for back-end use.
10729 (Apply_Float_Conversion_Check): Handle case where the conversion is
10731 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10748 parameters when deciding whether to apply a run-time accessibility
10750 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10751 aggregate code before allocator, and ahead of declaration for
10752 temporary, to prevent access before elaboration when the allocator is
10753 an actual for an access parameter.
10754 (Expand_N_Type_Conversion): On an access type conversion involving an
10755 access parameter, do not apply an accessibility check when the
10756 operand's original node was an attribute other than 'Access. We now
10757 create access conversions for the expansion of 'Unchecked_Access and
10758 'Unrestricted_Access in certain cases and clearly accessibility should
10759 not be checked for those.
10761 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10762 includes a type conversion of a packed component that has been expanded,
10763 recover the original expression for the object, and use this expression
10764 in the post-call assignment statement, so that the assignment is made
10765 to the object and not to a back-end temporary.
10766 (Freeze_Subprogram): In case of primitives of tagged types not defined
10767 at the library level force generation of code to register the primitive
10768 in the dispatch table. In addition some code reorganization has been
10769 done to leave the implementation clear.
10770 (Expand_Call): When expanding an inherited implicit conversion,
10771 preserve the type of the inherited function after the intrinsic
10772 operation has been expanded.
10774 * exp_ch2.ads, exp_ch2.adb
10775 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10776 of an entry formal appearing in an assignment statement does not assign
10778 (Expand_Current_Value): Instead of calling a routine to determine
10779 whether the prefix of an attribute reference should be optimized or
10780 not, prevent the optimization of such prefixes all together.
10782 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10783 component whose prefix is known to be of an access type is an implicit
10784 dereference and does not assign to the prefix.
10786 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10787 Robert Dewar <dewar@adacore.com>
10789 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10790 itype is visited, make an entry into table to link associated node and
10792 Add comments and correct harmless error in Build_NCT_Hash_Tables
10793 (Array_Aggr_Subtype): Associate each itype created for an index type to
10794 the corresponding range construct, and not to the aggregate itself. to
10795 maintain a one-to-one correspondence between itype and its associated
10796 node, to prevent errors when complex expression is copied.
10797 Fix mishandling of multiple levels of parens
10799 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10800 treatment of limited views uniform for all visible declarations in a
10801 limited_withed package.
10802 (New_Copy_Tree): If hash table is being used and itype is visited,
10803 make an entry into table to link associated node and new itype.
10804 (Resolve_Record_Aggregate): Do not add an others box association for a
10805 discriminated record component that has only discriminants, when there
10806 is a box association for the component itself.

10855 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10856 generation of a freezing node to ensure proper management of null
10857 excluding access types in the backend.
10858 (Create_Extra_Formals): Test base type of the formal when checking for
10859 the need to add an extra accessibility-level formal. Pass the entity E
10860 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10861 originally being done in a couple of cases), to ensure that the
10862 Extra_Formals list gets set on the entity E when the first entity is
10864 (Conforming_Types): Add missing calls to Base_Type to the code that
10865 handles anonymous access types. This is required to handle the
10866 general case because Process_Formals builds internal subtype entities
10867 to handle null-excluding access types.
10868 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10869 functions that need it, even when not marked Requires_Overriding.
10870 Improve warnings for in out parameters
10871 (Analyze_Function_Return): Warn for disallowed null return
10872 Warn on return from procedure with unset out parameter
10873 Ensure consistent use of # in error messages
10874 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10875 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10876 the implicit conversion of the expression done for anonymous access
10877 types. This is required to generate the code of the null excluding
10878 check (if required).
10880 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10881 A formal parameter is never publicly referenceable outside of its body.
10882 (Check_References): For an unreferenced formal parameter in an accept
10883 statement, use the same warning circuitry as for subprogram formal
10885 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10886 Output_Unreferenced_Messages, containing the part of that routine that
10887 is now reused for entry formals as described above.
10888 (Goto_Spec_Entity): New function
10889 (Check_References): Do not give IN OUT warning for dispatching operation
10890 Improve warnings for in out parameters

10897 Javier Miranda <miranda@adacore.com>
10898 Gary Dismukes <dismukes@adacore.com>
10900 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10901 (Expand_N_Attribute_Reference): Further unify the handling of the
10902 three forms of access attributes, using common code now for all three
10903 cases. Add a test for the case of applying an access attribute to
10904 an explicit dereference when the context is an access-to-interface
10905 type. In that case we need to apply the conversion to the prefix
10906 of the explicit dereference rather than the prefix of the attribute.
10907 (Attribute_Version, UET_Address): Set entity as internal to ensure
10908 proper dg output of implicit importation.
10909 (Expand_Access_To_Type): Removed.
10910 (Expand_N_Attribute_Reference): Merge the code from the three cases
10911 of access attributes, since the processing is largely identical for
10912 these cases. The substantive fix here is to process the case of a
10913 type name prefix (current instance case) before handling the case
10914 of interface prefixes.

10919 Robert Dewar <dewar@adacore.com>
10921 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10922 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10923 type that is an anonymous access to controlled object, establish
10924 an associated finalization chain to avoid corrupting the global
10925 finalization list when a dynamically allocated object designated
10926 by such a component is deallocated.
10927 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10928 functions that need it, even when not marked Requires_Overriding.
10929 (Initialize_Tag): Replace call to has_discriminants by call to
10930 Is_Variable_Size_Record in the circuitry that handles the
10931 initialization of secondary tags.
10932 (Is_Variable_Size_Record): New implementation.
10933 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10934 Suppress_Initialization pragma for a derived type.
10935 (Is_Variable_Size_Record): New subprogram.
10936 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10937 initial version of this routine and also fixes problems causing
10938 incomplete initialization of the table of interfaces.
10939 (Build_Init_Procedure): Improve the generation of code to initialize the
10940 the tag components of secondary dispatch tables.
10941 (Init_Secondary_Tags): New implementation that simplifies the previous
10942 version of this routine.
10943 (Make_DT): Add parameter to indicate when type has been frozen by an
10944 object declaration, for diagnostic purposes.
10945 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10946 diagnose attemps to freeze a subprogram when some untagged type of its
10947 profile is a private type whose full view has not been analyzed yet.
10948 (Freeze_Array_Type): Generate init proc for packed array if either
10949 Initialize or Normalize_Scalars is set.
10950 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10951 constructing the new profile, copy the null_exclusion indicator for each
10952 parameter, to ensure full conformance of the new body with the spec.
10954 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10955 Create wrappers for constructor functions that need it, even when not
10956 marked Requires_Overriding.
10957 (Covers): Handle properly designated types of anonymous access types,
10958 whose non-limited views are themselves incomplete types.
10959 (Add_Entry): Use an entity to store the abstract operation which hides
10961 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10962 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10963 initialization aggregate.
10964 (Function_Interp_May_Be_Hidden): Rename to
10965 Function_Interp_Has_Abstract_Op.
10966 (Has_Compatible_Type): Remove machinery that skips interpretations if
10967 they are labeled as potentially hidden by an abstract operator.
10968 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10969 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10970 (Write_Overloads): Output the abstract operator if present.
10971 (Add_Entry): Before inserting a new entry into the interpretation table
10972 for a node, determine whether the entry will be disabled by an abstract

10975 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10977 (Function_Interp_May_Be_Hidden): New routine.
10978 (Has_Compatible_Type): Do not consider interpretations hidden by
10979 abstract operators when trying to determine whether two types are
10981 (Has_Hidden_Interp): New routine.
10982 (Set_May_Be_Hidden_Interp): New routine.
10983 (Write_Overloads): Write the status of flag May_Be_Hidden.

10989 types declared in the declarative part of a nested package body or in
10990 the proper body of a stub.
10991 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10992 of the same dispatch table slot to renamed primitives.
10993 (Make_Select_Specific_Data_Table): Handle private types.
10994 (Tagged_Kind): Handle private types.
10995 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10996 output of implicit importation and exportation.
10997 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10998 first formal of the thunk is always associated with the controlling
10999 type. In addition perform the following code cleanup: remove formal
11000 Thunk_Alias which is no longer required, cleanup evaluation of the
11001 the controlling type, and update the documentation.
11002 Replace occurrence of Default_Prim_Op_Count by
11003 Max_Predef_Prims. Addition of compile-time check to verify
11004 that the value of Max_Predef_Prims is correct.
11005 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11006 (Make_DT): Add parameter to indicate when type has been frozen by an
11007 object declaration, for diagnostic purposes.
11008 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11009 construction of statically allocated dispatch tables.
11010 (Make_DT): In case of library-level tagged types export the declaration
11011 of the primary tag. Remove generation of tags (now done by Make_Tags).
11012 Additional modifications to handle non-static generation of dispatch
11013 tables. Take care of building tables for asynchronous interface types
11014 (Make_Tags): New subprogram that generates the entities associated with
11015 the primary and secondary tags of Typ and fills the contents of Access_
11016 Disp_Table. In case of library-level tagged types imports the forward
11017 declaration of the primary tag that will be declared later by Make_DT.
11018 (Expand_Interface_Conversion): In case of access types to interfaces
11019 replace an itype declaration by an explicit type declaration to avoid
11020 problems associated with the scope of such itype in transient blocks.

11023 Ed Schonberg <schonberg@adacore.com>
11024 Javier Miranda <miranda@adacore.com>
11026 * exp_util.ads, exp_util.adb:
11027 This patch replaces a number of occurrences of explicit tests for N_Null
11028 with calls to Known_Null. This improves tracking of null values, since
11029 Known_Null also catches null constants, and variables currently known to
11030 be null, so we get better tracking.
11031 (Ensure_Defined): create an itype reference only in the scope of the
11033 (Side_Effect_Free): A selected component of an access type that
11034 denotes a component with a rep clause must be treated as not
11035 side-effect free, because if it is part of a linked structure its
11036 value may be affected by a renaming.
11037 (Expand_Subtype_From_Expr): For limited objects initialized with build
11038 in place function calls, do nothing; otherwise we prematurely introduce
11039 an N_Reference node in the expression initializing the object, which
11040 breaks the circuitry that detects and adds the additional arguments to
11041 the called function. Bug found working in the new patch for statically
11042 allocated dispatch tables.
11043 (Is_Library_Level_Tagged_Type): New subprogram.
11044 (Remove_Side_Effects): If the expression of an elementary type is an
11045 operator treat as a function call.
11046 (Make_Literal_Range): If the index type of the array is not integer, use
11047 attributes properly to compute the constraint on the resulting aggregate
11050 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11051 class-wide type whose base type is an incomplete private type, leave
11052 class-wide type unfrozen so that freeze nodes can be generated
11053 properly at a later point.
11054 (Freeze_Entity, array case): Handle case of pragma Pack and component
11055 size attributre clause for same array.

11112 attribute Body in package Naming. Do not replace a source/unit in the
11113 same project when the order of the source dirs are known. Detect
11114 duplicate sources/units in the same project when the order of the
11115 source dirs are not known.
11116 (Check_Ada_Name): Allow all identifiers that are not reserved words
11118 Major update of the Project Manager and of the project aware tools,

11122 directory of non extending project to nil.
11123 Change type of path name variables to be Path_Name_Type

11729 (Complete_Object_Operation): If actual has an access type and
11730 controlling formal is not an in_parameter, reject the actual if it is
11731 an access_to_constant type.
11732 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11733 type, the candidate operations are found in the scope of declaration of
11734 the type, because the type has no primitive subprograms.
11735 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11736 a private extension, only examine visible components before trying to
11737 analyze as a prefixed call.
11738 Change Entity_List to Type_To_Use, for better readability.

11751 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11752 purpose of enforcing E.2.2(8) only if it is not available at any place.
11753 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11754 when checking the legality of an extension aggregate in a preelaborable
11755 package. Treat the literal null as a valid default expression in a
11756 component declaration for a type with preelaborable initialization.
11757 A limited interface is a legal progenitor for the designated type of a
11758 remote access to class-wide type.

11775 subprogram generic actual for which we have generated a renaming.

11791 (Resolve_Actuals): When verifying that an access to class-wide object
11792 is an actual for a controlling formal, ignore anonymous access to
11793 subprograms whose return type is an access to class_wide type.
11794 (Resolve_Slice): If the prefix of the slice is a selected component
11795 whose type depends on discriminants, build its actual subtype before
11796 applying range checks on the bounds of the slice.
11797 (Valid_Conversion): In an instance or inlined body, compare root types,
11798 to prevent anomalies between private and public views.

11820 elabration statements, register the package with the name server
11821 at the beginning, not at the end, of the elaboration statements so

13011 prefix if the prefix has a synchronized type and the type of the formal
13012 is its corresponding record, as can be the case when the primitive
13013 operation is declared outside of the body of the type.
13014 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13015 perform homonym traversal, looking for class-wide operation matches
13016 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13017 access parameters are now restricted to anonymous access types.
13018 (Mark_Allocator): An allocator with a discriminant association parent is
13020 (Try_One_Prefix_Interpretation): If the type of the object is
13021 incomplete, as can be happen when it is a limited view obtained through
13022 a limited_with_clause, the selected component is not part of a prefixed
13024 (Complete_Object_Operation): Diagnose properly an object that is not
13025 aliased when the corresponding controlling formal is an access
13027 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13028 ambiguous calls in prefixed notation, where two primitives differ only
13029 in that the controlling argument of one is an access parameter.
13031 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13032 whether a function that returns an unconstrained type can be inlined.
13033 (Process_Formals): Diagnose properly the illegal use of an incomplete
13034 type in the profile of an access_to_subprogram declaration.
13035 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13036 operations are attached to the corresponding record.
13037 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13038 When processing a primitive of a concurrent type which implements an
13039 interface change the type of all controlling formals to that of the
13040 corresponding record type.
13041 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13042 to determine the tagged type to which a primitive belongs.
13043 (Check_Conventions): Capture condition to ignore a primitive operation
13044 (which is shared between the loop in Check_Conventions and the one in
13045 Check_Convention) in a new local function Skip_Check.
13046 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13047 confusion with Check_Conventions' own Prim_Op local variable.
13048 (Create_Extra_Formals): Test for a tagged result type rather than a
13049 controlling result when determining whether to add a BIP_Alloc_Form
13050 formal and a BIP_Final_List formal to the function.
13051 (Check_Conformance); For parameters that are anonymous access types,
13052 subtype conformance requires that the not null and the constant
13053 indicators must match
13054 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13055 to retrieve the appropriate type when processing a concurrent type
13056 declared within a generic. Minor comment reformatting. Change invocation
13057 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13059 (Analyze_Subprogram_Body): If the return type of a function is an
13060 anonymous access to the limited view of a class-wide type, and the
13061 non-limited view of the type is available, update the type of the
13062 function so that code can be generated.
13063 (Process_Formals): In case of access-subtype itype whose designated
13064 type is also an itype (situation that happens now with access to
13065 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13066 attribute to avoid backend problems.
13067 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13068 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13069 anonymous types' designated types are same before testing
13070 Subtypes_Statically_Match.
13071 (Create_Extra_Formals): Test for a named access parameter that is a
13072 controlling formal as an additional condition for adding an
13073 accessibility level formal. This can occur in the subp type created for
13074 dispatching calls in Expand_Dispatching_Call, and allows calling
13075 Create_Extra_Formals from that procedure rather than special-casing the
13076 extra formals there.
13077 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13078 when the function has a controlling result.
13079 (Check_Returns): Add much more knowledge of the optimization of local
13080 raise statements to gotos, to retain proper warnings in this case.
13081 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13082 nodes when looking for last statement.
13084 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13085 class-wide types visible through limited with clauses.
13086 (Add_One_Interp): If the operands are anonymous access types, the
13087 predefined operator on universal_access is immediately visibles
13088 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13089 other anonymous access types.
13090 (Disambiguate): Take into account CIL convention.
13091 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13093 2007-06-06 Robert Dewar <dewar@adacore.com>
13095 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13096 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13097 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13098 Fix lower bound of tables.
13101 * nlists.adb: Ditto.
13102 (Prev_Node, Next_Node): Change index type to Int so that it properly
13103 covers the range First_Node_Id - 1 up.
13105 2007-06-06 Javier Miranda <miranda@adacore.com>
13106 Ed Schonberg <schonberg@adacore.com>
13107 Bob Duff <duff@adacore.com>
13108 Hristian Kirtchev <kirtchev@adacore.com>
13110 * exp_aggr.ads, exp_aggr.adb:
13111 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13112 in extension aggregates.
13113 (Flatten): Other conditions being met, an aggregate is static if the
13114 low bound given by component associations is different from the low
13115 bound of the base index type.
13116 (Packed_Array_Aggregate_Handled): If the component type is itself a
13117 packed array or record, the front-end must expand into assignments.
13118 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13119 Init_Pr, instead of Ancestor_Is_Expression.
13120 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13121 coextension chain root, either generate a list controller or use the
13122 already existing one.
13123 (Static_Array_Aggregate): New procedure to construct a positional
13124 aggregate that can be handled by the backend, when all bounds and
13125 components are compile-time known constants.
13126 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13127 types covering interface types into assignments.
13128 (Replace_Type): move to Build_Record_Aggr_Code.
13129 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13130 interface type, convert to the definite type of the aggregate itself,
13131 so that needed components are visible.
13132 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13133 components and the context is an extended return statement do not
13134 create a transient block for it, to prevent premature finalization
13135 before the return is executed.
13136 (Gen_Assign): Do not generate a call to deep adjust routine if the
13137 component type is itself an array of controlled (sub)-components
13138 initialized with an inner aggregate.
13139 (Component_Check): New name for Static_Check. This name is now more
13140 appropriate, and documentation is added which was missing.
13141 (Component_Check): Add test for bit aligned component value
13142 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13143 Tagged_Comps, name is more appropriate given added function below.
13144 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13146 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13147 Javier Miranda <miranda@adacore.com>
13148 Robert Dewar <dewar@adacore.com>
13150 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13151 Terminated: Add unchecked type conversion from System.Address to
13152 System.Tasking.Task_Id when calling the predefined primitive
13154 Disable new Ada 05 accessibility check for JVM.NET targets, which
13155 cannot be implemented in a practical way.
13156 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13157 the sources always references the tag of the actual object. Therefore,
13158 if 'Tag is applied in the sources to class-wide interface objects we
13159 generate code that displaces "this" to reference the base of the object.
13160 (Expand_N_Attribute_Reference, case Size): Return specified size if
13161 known to front end.
13162 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13163 has code that displaces the pointer of the object to manage interface
13164 types. However this code must not be executed when the prefix is a
13165 subprogram. This bug caused the wrong expansion of the internally
13166 generated assignment that fills the dispatch table when the primitive
13167 is a function returning a class-wide interface type.
13168 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13169 Set_Attribute_Name for Name_Unaligned_Valid.
13171 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13172 Gary Dismukes <dismukes@adacore.com>
13174 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13175 If the initialization is the equivalent aggregate of the initialization
13176 procedure of the type, do not remove it.
13177 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13178 initialized to null from having their expression reset to empty and
13179 note this exception in the comment.
13181 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13182 Robert Dewar <dewar@adacore.com>
13183 Ed Schonberg <schonberg@adacore.com>
13184 Gary Dismukes <dismukes@adacore.com>
13186 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13187 Add "with" and "use" clauses for Sem_Attr.
13188 (Expand_Current_Value): Do not replace occurences of attribute
13189 references where the prefix must be a simple name.
13191 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13192 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13193 Attribute_Requires_Simple_Name_Prefix.
13194 (Name_Modifies_Prefix): Body of new function.
13195 (Requires_Simple_Name_Prefix): Body of new function.
13196 (Resolve_Attribute, case Access): Improve error message for case of
13197 mismatched conventions.
13198 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13200 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13201 constrained subtype for a nominal unconstrained type, use its base type
13202 to check for conformance with the context.
13203 (Resolve_Attribute): Remove test of the access type being associated
13204 with a return statement from condition for performing accessibility
13205 checks on access attributes, since this case is now captured by
13206 Is_Local_Anonymous_Access.
13207 (Analyze_Access_Attribute): Set Address_Taken on entity
13208 (Analyze_Attribute, case Address): Set Address_Taken on entity
13209 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13210 validating an access attribute whose prefix is a current instance.
13211 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13212 applied to dispatching operations, if freezing is required then we set
13213 the attribute Has_Delayed_Freeze in the prefix's entity.
13214 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13215 current scope if access of local subprogram taken
13216 (Analyze_Access_Attribute): Check legality of self-reference even if the
13217 expression comes from source, as when a single component association in
13218 an aggregate has a box association.
13219 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13220 the prefix if it is a protected operation and the attribute is
13221 Unrestricted_Access.
13222 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13223 reference to the base type of the context, to force a constraint check
13224 when the context is an access subtype with an explicit constraint.
13225 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13226 node is rewritten as an interface conversion. leave unanalyzed after
13227 resolution, to ensure that type checking against the context will take

13231 Javier Miranda <miranda@adacore.com>
13232 Robert Dewar <dewar@adacore.com>
13234 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13235 wrapper when the full view of the controlling type of an inherited
13236 function that dispatches on result implements interfaces.
13237 (Expand_N_Object_Declaration): In cases where the type of the
13238 declaration is anonymous access, create finalization list for it.
13239 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13240 if the object has no explicit initialization, to match description of
13241 functionality of pragam Persistent_BSS.
13242 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13243 new function to build static aggregates, to replace initialization call
13244 when static initialization is desired.
13245 (Freeze_Type): Generate a list controller for an access type whenever
13246 its designated type has controlled anonymous access discriminants.
13247 (Build_Equivalent_Aggregate): New procedure to compute a static
13248 aggregate to be used as default initialization for composite types,
13249 instead of a generating a call to the initialization procedure for the
13251 (Build_Initialization_Call): When available, replace a call to the
13252 initialization procedure with a copy of the equivalent static aggregate
13254 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13255 declarations for objects of a class-wide interface type, rather than
13256 just identifiers, to prevent visibility problems.
13257 (Expand_N_Object_Declaration): When expanding the declaration for an
13258 object of a class-wide interface type, preserve the homonym chain of
13259 the original entity before exchanging it with that of the generated
13260 renaming declaration.
13261 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13262 active, because there is no way to handle the exception.
13263 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13264 to do a minimum decoration of the Access_Disp_Table list.
13265 (Expand_Record_Controller): Avoid the addition of the controller between
13266 the component containing the tag of a secondary dispatch table and its
13267 adjacent component that stores the offset to the base of the object.
13268 This latter component is only generated when the parent type has
13269 discriminants ---documented in Add_Interface_Tag_Components).
13270 (Apply_Array_Size_Check): Removed, no longer needed.
13271 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13272 components, create a Master_Entity for it only if it contains tasks.
13273 (Build_Init_Procedure): Suppress the tag assignment compiling under
13275 (Freeze_Record_Type): Remove code associated with creation of dispatch
13277 (Init_Secondary_Tags): Update type of actuals when generating calls to
13278 Ada.Tags.Set_Offset_To_Top
13279 (Stream_Operation_OK): Disable use of streams compiling under no
13281 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13282 if Has_Init_Expression set.
13283 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13284 Register_Primitive, which provides the same functionality.
13285 (Requires_Init_Proc): Return false in case of interface types.
13286 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13288 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13289 is always associated with a predefined primitive because the internal
13290 entities associated with interface types are not predefined primitives.
13291 Therefore, the call to Is_Internal is replaced by a call to the
13292 function Is_Predefined_Dispatching_Operation.
13293 (Make_Eq_If): When generating the list of comparisons for the
13294 components of a given variant, omit the controller component that is
13295 present if the variant has controlled components.
13297 2007-06-06 Javier Miranda <miranda@adacore.com>
13298 Hristian Kirtchev <kirtchev@adacore.com>
13299 Bob Duff <duff@adacore.com>
13301 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13302 handle the creation of finalization lists and calls for nested
13303 coextensions when the root of the chains is part of a return statement.
13304 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13306 (Expand_Record_Equality): Skip components that are interface types.
13307 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13308 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13309 with Rewrite_Coextension. Change the condition for detecting coextension
13311 (Is_Local_Access_Discriminant): Removed.
13312 (Rewrite_Coextension): New routine which rewrites a static coextension
13313 as a temporary and uses its unrestricted access in the construction of
13315 (Complete_Coextension_Finalization): New routine. Generate finalization
13316 attachment calls to all delayed coextensions.
13317 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13318 the allocator is not a coextension itself and has delayed coextensions.
13319 If the current allocator is controlled, but also a coextension, delay
13320 the generation of the finalization attachment call.
13321 Rename local variable "Node" to "Nod" in order to avoid confusion with
13323 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13324 limited types that are not inherently limited. Such an allocator is
13325 illegal, but is generated by the expander for a return statement, to
13326 copy the result onto the secondary stack. This is the only case where a
13327 limited object can be copied. Generate code to displace the pointer
13328 to the object if the qualified expression is a class-wide interface
13329 object. Such displacement was missing and hence the copy of the object
13331 (Apply_Accessibility_Check): Handle allocated objects initialized in
13333 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13334 and Expand_Allocator_Expression. Allocating class-wide interface objects
13335 this routine displaces the pointer to the allocated object to reference
13336 the component referencing the corresponding secondary dispatch table.
13337 Expand_Allocator_Expression): Add missing support to allocate class-wide
13338 interface objects initialized with a qualified expression.
13339 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13340 function result type, and use the finalization list associated with the
13341 function scope in that case (such an anonymous type should not be
13342 treated like an access parameter's type).
13344 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13345 Gary Dismukes <dismukes@adacore.com>
13346 Javier Miranda <miranda@adacore.com>
13348 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13349 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13350 required exception handler.
13351 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13352 properly the case of a function whose return type is a limited
13353 class-wide interface type. Modify the code of the accessibility
13354 check to handle class-wide interface objects. In this case we need to
13355 displace "this" to reference the primary dispatch table to get access
13356 to the TSD of the object (to evaluate its accessibility level).
13357 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13358 rather than a controlling result as one of the conditions for
13359 generating tests of the implicit BIP_Alloc_Form formal. The
13360 initialization assignment is also handled according to whether the
13361 result is tagged instead of controlling.
13362 In the case where the init assignment is inserted in the "then" part of
13363 the allocation conditional, rewrite the target to be a dereference of
13364 the implicit BIP_Object_Access formal.
13365 If the returned value is unconstrained and created on the secondary
13366 stack, mark the enclosing block and function so that the secondary
13367 stack is not reclaimed on return.
13368 Treat returns from functions with controlling results similarly to
13369 returns from functions with unconstrained result subtypes.
13370 If the object returned is unconstrained, and an allocator must be
13371 created for it, analyze the allocator once the block for the extended
13372 return is installed, to ensure that finalizable components
13373 of the expression use the proper finalization list. Guard the call to
13374 Move_Final_List with a check that there is something to finalize.
13375 (Make_Tag_Ctrl_Assignment): Use "old" handling
13376 of controlled type assignment for virtual machines, since new code uses
13377 unsupported features (such as direct access to bytes in memory).
13379 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13380 Ed Schonberg <schonberg@adacore.com>
13382 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13383 accessibility actual, check for the case of an aliased object that has
13384 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13385 we fall into processing for the attribute rather than the name of the
13387 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13388 formal has its address taken in the body, create a temporary to capture
13389 value. If the return type is a limited interface, do not treat the
13390 return value as Controlled.
13391 (Is_In_Place_Function): If the return type is a limited interface,
13392 treat as returning in place. The actual returned object may not always
13393 be limited, but the caller has to assume that it is returned in place.
13394 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13395 context of an allocator, use the correct finalization chain (that is,
13396 the chain belonging to the access type, rather than the chain belonging
13397 to the current scope).
13398 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13399 result type rather than a controlling result as a precondition for
13400 adding an allocation form actual to a build-in-place call.
13401 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13402 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13403 primitive in the dispatch tables. This work is now done by Make_DT when
13404 the type is frozen.
13405 (Register_Predefined_DT_Entry): Removed.
13406 (Add_Return): If end label is not present, use sloc of last statement
13407 for generated return statement in procedure, for better gdb behavior
13409 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13410 object address nodes to ensure proper processing by routines like
13412 (Expand_Call): Fix generation of validity check for parameter
13413 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13414 the allocation form parameter if the result subtype is constrained,
13415 except when the function has a controlling result.
13416 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13417 rather than Is_Controlled and Has_Controlled_Component, since we want to
13418 include class-wide result types in this treatment. Also test for a
13419 controlling result, since that also requires passing a finalization
13421 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13422 even when the result subtype is constrained, to handle calls involving
13423 controlling results.
13424 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13425 is now called even when the result subtype is constrained, to handle
13426 calls involving controlling results.
13427 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13428 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13429 now performs the test).
13430 (Make_Build_In_Place_Call_In_Object_Declaration):
13431 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13432 constrained, to handle calls involving controlling results.
13433 (Add_Return): Accomodate rewritten pattern from local raise to goto

13454 subprogram instead of a plain "raise Program_Error" node to raise
13455 Program_Error if an exception is propagated from an Adjust or Finalize
13457 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13458 appears in the optional statement list of a triggering alternative, the
13459 scope actions can be inserted directly there, and not in the list that
13460 includes the asynchronous select itself.

13490 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13491 functionality when the backend is generating code.
13492 Otherwise any serious error
13493 reported by the backend calling the frontend routine Error_Msg
13494 changes the Compilation_Mode to Check_Semantics, disables the

13535 deallocation of class-wide interface objects.
13536 (Expand_Dispatching_Constructor_Call): Take into account that if the
13537 result of the dispatching constructor is an interface type, the
13538 function returns a class-wide interface type; otherwise the returned
13539 object would be actual. The frontend previously accepted returning
13540 interface types because Expand_Interface_Actuals silently performed
13541 the management of the returned type "as if" it were a class-wide
13543 (Expand_Dispatching_Constructor_Call): Replace call to
13544 Make_DT_Access_Action by direct call to Make_Function_Call.

13636 subtype from the function call, as is done for private types.
13637 (Side_Effect_Free): An expression that is the renaming of an object or
13638 whose prefix is the renaming of a object, is not side-effect free
13639 because it may be assigned through the renaming and its value must be
13640 captured in a temporary.

13753 defined in GNAT.IO, which might not be stdout
13754 (Is_Valid): Adjust comment to mention that a positive reply means that
13755 Header_Of may be used to retrieve the allocation header associated with

14369 aggregate of a discriminated type, check that associations for any
14370 access discriminants satisfy accessibility requirements by calling

14393 both entities. This is required to statically build the dispatch table.
14394 (Declare_Inherited_Private_Subprograms): Rewriten to avoid the need
14395 of calling Set_All_DT_Position to re-evaluate the position of the
14396 entries in the dispatch table. Such reevaluation is not desired if

15265 (Resolve_Call): If the call returns an array, the context imposes the
15266 component type of the array, and the function has one non-defaulted
15267 parameter, rewrite the call as the indexing of a call with a single
15268 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15270 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15271 the master of the created object is the innermost enclosing statement.
15272 (Remove_Conversions): For a binary operator, check if type of second
15273 formal is numeric, to check if an abstract interpretation is present

15371 (Requires_Overriding): Add this new flag, because "requires
15372 overriding" is subtly different from "is abstract" (see AI-228).
15373 (Is_Abstract): Split Is_Abstract flag into Is_Abstract_Subprogram and
15374 Is_Abstract_Type. Make sure these are called only when appropriate.

15436 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15437 "abstract subprograms must be visible" message, whether or not the type

15520 that use (a subtype of) the class-wide type of the enclosing type.
15521 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15522 Derived_Type for Prev formal on call to
15523 Check_Anonymous_Access_Components rather than Empty.
15524 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15525 a record extension in deciding whether to create a class-wide type,

15580 (Initialize): Add the directory where gnatmake is invoked in front of
15581 the path if it is invoked from a bin directory, even without directory

15606 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15607 when -gnatg is not specified.

15659 parameter of the containing subprogram.
15660 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15661 under No_Dispatching_Calls restriction. During the semantic analysis

15685 of the table of ancestors.
15686 (Expand_Interface_Conversion): Insert function body at the closest place
15687 to the conversion expression, to prevent access-before-elaboration
15688 errors in the backend.

15714 (Expand_Dispatching_Call): Replace generation of call to the run-time
15715 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15716 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15718 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15719 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

15729 returns an actual parameter expression for both named and positional
15732 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15733 check violation of restriction No_Dispatching_Calls.
15734 (Check_Controlling_Type): A formal of a tagged incomplete type is a

15741 specify Any_Limited_Interface, and this functionality is already
15742 provided by the function Has_Abstract_Interfaces.
15743 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15744 support concurrent types implementing interfaces.
15745 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15746 specify kind Any_Limited_Interface, and this functionality is already

15763 Cyrille Comar <comar@adacore.com>
15765 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15766 anonymous, use finalization list of enclosing dynamic scope.
15767 (Expand_N_Package_Declaration): For a library package declaration
15768 without a corresponding body, generate RACW subprogram bodies in the
15769 spec (just as we do for the task activation call).
15770 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15771 Is_Abstract_Type. Make sure these are called only when appropriate.
15772 Remove all code for DSP option
15773 (CW_Or_Controlled_Type): new subprogram.

15777 Gary Dismukes <dismukes@adacore.com>
15779 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15780 parameter. If it is set to true, return a result capped according to
15781 the global upper bound for the index of an entry family.
15782 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15783 (Build_Find_Body_Index): Adjust for above change.
15784 (Entry_Index_Expression): Likewise.
15785 (Is_Potentially_Large_Family): New function extracted from...

15787 is potentially large.
15788 (Build_Entry_Count_Expression): If the family is potentially large, call
15789 Family_Size with 'Cap' set to true.
15790 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15791 a protected version of an operation declared in the private part of
15792 a protected object, because they may be invoked through a callback.
15793 (Set_Privals): If the type of a private component is an anonymous access
15794 type, do not create a new itype for each protected body.
15795 If the body of a protected operation creates
15796 controlled types (including allocators for class-widetypes), the
15797 body of the corresponding protected subprogram must include a
15799 (Build_Activation_Chain_Entity): Build the chain entity for extended
15801 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15802 to determine whether operation overrides an inherited primitive.
15803 (Build_Wrapper_Spec): Add code to examine the parents while looking
15804 for a possible overriding candidate.
15805 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15806 hold an actual parameter value since its initialization is separated

15810 2007-04-06 Thomas Quinot <quinot@adacore.com>
15811 Pablo Oliveira <oliveira@adacore.com>
15813 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15814 Do an Unchecked_Conversion to handle the passage from the Underlying
15815 Type to the Base Type when calling Build_To_Any_Call and
15816 Build_From_Any_Call.
15817 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15818 E_Constant, depending upon Variable formal.
15819 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15820 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15821 parameter that requires an extra constrained parameter, declare
15822 temporary for actual as a variable, not a constant.
15823 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15824 the unit being compiled is the one that contains the stub type.
15825 Change primitive operation name for the RACW associated with a RAS
15826 from Call to _Call so it cannot clash with any legal identifier.
15827 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15829 (Append_RACW_Bodies): New subprogram.
15830 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15831 Add_Receiving_Stubs_To_Declarations functions.
15832 When expanding a package body, this list correspond to the
15833 statements in the HSS at the end of the pacakge.
15834 When expanding a package spec, this list correspond to the
15836 (Add_Receiving_Stubs_To_Declarations): Append the function
15837 registering the receiving stubs at the end of the 'Stmts' list.
15838 (RCI_Package_Locator): Pass the new Version generic formal when
15839 instantiating a RCI_Locator package.
15840 (Build_From_Any_Function): To compute the High bound for an
15841 unconstrained array actual, we add the Low bound with the length.
15842 Thus we must convert the low bound and the length to an appropriate
15843 type before doing the sum.
15844 (Build_Subprogram_Receiving_Stubs, PolyORB):
15845 * Retrieve the extra formals parameters at the
15846 end of the parameter stream.
15847 * Use Move_Any_Value to write back out parameters
15848 after executing the request as it is more efficient
15849 than Copy_Any_Value.
15850 * Build the any containing Extra Formals with the
15851 appropriate typecode.
15852 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15853 empty Component_List.
15854 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15855 the tree the declaration for an object that serves as actual parameter
15856 in server-side stubs.
15857 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15858 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15859 Use Build_Actual_Object_Declaration to prepare the actuals.

15861 Extra Constrained Parameters.
15862 (Build_General_Calling_Stubs): Set the parameter type to boolean for
15863 Extra Constrained parameters.

15866 function with the first not implicit parent type.
15867 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15868 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15869 typecode from the Etype. Therefore we retrieve the correct typecode
15870 with a call to Get_Any_Type.
15871 (Copy_Specification): Do controlling formal type substitution based on
15872 Is_Controlling_Formal flag, instead of caller-provided object type.
15873 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15874 a RACW primitive operation, we might get a subprogram declaration for an
15875 ancestor of the RACW designated type (not for the designated type
15876 itself), in the case where this operation is inherited. In this case we
15877 have no easy means of determining the original tagged type for which
15878 the primitive was declared, so instead we now rely on
15879 Copy_Specification to use the Is_Controlling_Formal flag to determine
15880 which formals require type substitution.

15886 GNAT.Current_Exception are not allowed if pragma Restrictions
15887 (No_Exception_Propagation) is set and in any case make the associated
15888 handler unsuitable as a target for a local raise statement.
15889 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15890 run-time subprogram CW_Membership by call to Build_CW_Membership.
15891 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15892 by a function call, a temporary must be created before expanding the
15893 Constructor_Call itself, to prevent out-of-order elaboration in the
15894 back-end when stack checking is enabled..
15896 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15898 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15899 result are the bounds of the left operand, not the right.
15901 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15904 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15916 box corresponds to a component of the type.
15917 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15918 Is_Abstract_Subprogram and Is_Abstract_Type.

15923 * inline.adb (Add_Inlined_Body): Split Is_Abstract flag into
15924 Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
15925 called only when appropriate.

15933 offering facilities for all the Vector/View conversion routines
15934 implemented by this unit.

16023 standard 8bits encoding.
16024 (WS2SU): As above but converting from wide-sring to string.
16025 This is needed as it is necessary to have access to both versions in the
16026 runtime for the form parameter encoding support.
16027 This set of patch add support for the encoding form parameter.
16028 (S2WS): Improve implementation to handle cases where the filename is not
16029 UTF-8 encoded. In this case we default to using the current code page
16030 for the conversion.

16077 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16078 __gnat_adjust_context_for_raise.
16079 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16080 implementation of floating point operations as native x86 targets.
16081 So the FPU should be initialized in the same way using finit. Fix
16082 floating point operations accuracy issues.

16100 Javier Miranda <miranda@adacore.com>
16102 * lib-xref.ads, lib-xref.adb:
16103 Modify the loop that collects type references, to include interface
16104 types that the type implements. List each of these interfaces when
16105 building the entry for the type.
16106 (Generate_Definition): Initialize component Def and Typ of new entry
16107 in table Xrefs, to avoid to have these components unitialized.

16153 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16154 it no longer destroys the contents of Name_Buffer or Name_Len and
16155 non-standard and invalid names are handled better.
16156 (Get_Decoded_Name_String): Improve performance by using
16157 Name_Has_No_Encodings flag in the name table.

16165 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16166 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16167 there is no need to generate always a record_definition_node in case
16168 of synchronized interface types.
16169 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16170 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16171 illegal in Ada 95, in cases where it is legal. Change the warnings to
16172 errors in other cases. Don't give the error unless the "not null"
16173 parses properly. Correct the source position at which the error occurs.
16174 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16175 P_Null_Exclusion, to suppress "not null" warnings.

16227 Entry for pragma Unreferenced_Objects
16229 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD

16251 the default project path, initially done during elaboration of the
16253 If the prefix returned by Sdefault is null, get the prefix from a call
16254 to Executable_Prefix_Path.
16255 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16258 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16259 canonical directory name to open the directory from which files are
16261 (Record_Other_Sources): Idem.
16262 (Locate_Directory): Add the possibility to create automatically missing
16263 directories when Setup_Projects is True.
16264 Call Locate_Directory so that the directory will be created when

16266 library source copy dir and exec dir.
16268 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16271 2007-04-06 Robert Dewar <dewar@adacore.com>

16306 full word is no longer compared twice.
16308 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16310 * sem_ch10.adb (Install_Limited_Context_Clauses.
16311 Expand_Limited_With_Clause): Use a new copy of selector name in the
16312 call to Make_With_Clause. This fixes the tree structure for ASIS
16313 purposes. Nothing is changed in the compiler behaviour.
16314 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16315 a package renaming.
16316 (Install_Limited_With_Clauses): Do not install non-limited view when it
16317 is still incomplete.
16319 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16320 Gary Dismukes <dismukes@adacore.com>
16322 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16323 when capturing size information, instead of base type, which for a
16324 formal array type will be the unconstrained type.
16325 (Analyze_Formal_Object_Declaration): Add check for illegal default
16326 expressions for a formal in object of a limited type.
16327 (Instantiate_Object): Ditto.
16328 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16329 because they were defaulted in the formal package and no check applies
16331 (Check_Formal_Package_Instance): Extend conformance check to other
16332 discrete types beyond Integer.
16333 (Process_Default): Copy directly the unmatched formal. A generic copy
16334 has already been performed in Analyze_Formal_Package.
16335 (Analyze_Associations): If a formal subprogram has no match, check for
16336 partial parametrization before looking for a default, to prevent
16338 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16339 not set the instantiation environment before analyzing the actuals.
16340 Fixes regression on 8515-003 with implementation of AI-133.
16341 Set_Instance_Env checks whether the generic unit is a predefined
16342 unit, in which case the instance must be analyzed with the latest Ada
16343 mode. This setting must take place after analysis of the actuals,
16344 because the actuals must be analyzed and frozen in the Ada mode extant
16345 outside of the current instantiation.
16346 (Save_Env, Restore_Env): Preserve and restore the configuration
16347 parameters so that predefined units can be compiled in the proper Ada
16349 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16350 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16351 and Is_Abstract_Type.
16352 (Analyze_Formal_Package): For better error recovery, Add exception
16353 handler to catch Instantion_Error, which can be raised in
16354 Analyze_Associations
16356 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16357 Bob Duff <duff@adacore.com>
16358 Gary Dismukes <dismukes@adacore.com>
16360 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16361 prefix type is a discriminated subtype of the type of the formal.
16362 (Analyze_Allocator): Collect all coextensions regardless of the context.
16363 Whether they can be allocated statically is determined in exp_ch4.
16364 (Analyze_Selected_Component): If the prefix is a limited view and the
16365 non-limited view is available, use the non-limited one.
16366 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16367 therefore illegal), suggest a qualified expression rather than a type
16368 conversion, because a type conversion would be illegal in this context.
16369 (Anayze_Allocator): Trace recursively all nested allocators so that all
16370 coextensions are on the corresponding list for the root. Do no mark
16371 coextensions if the root allocator is within a declaration for a stack-
16372 allocated object, because the access discriminants will be allocated on
16374 (Analyze_Call): Remove restriction on calls to limited functions for the
16375 cases of generic actuals for formal objects, defaults for formal objects
16376 and defaults for record components.
16377 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16378 element list. Their expansion is delayed until the enclosing allocator
16379 is processed and its finalization list constructed.
16380 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16381 for an operation with the given name among the primitive operations of
16382 the corresponding record type.
16383 (Analyze_Selected_Component): If the prefix is a task type that
16384 implements an interface, and there is no entry with the given name,
16385 check whether there is another primitive operation (e.g. a function)
16387 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16388 properly the indexing of a function call written in prefix form, where
16389 the function returns an array type, and all parameters of the function
16390 except the first have defaults.
16391 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16392 the original operands, rather than relocating them, for efficiency and
16393 to work properly when an operand is overloaded.
16394 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16395 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16396 (Analyze_Selected_Component): If the prefix is a private extension, only
16397 scan the visible components, not those of the full view.
16398 (Try_Primitive_Operation): If the operation is a procedure, collect all
16399 possible interpretations, as for a function, because in the presence of
16400 classwide parameters several primitive operations of the type can match
16401 the given arguments.
16403 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16404 Robert Dewar <dewar@adacore.com>
16406 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16407 tag-indeterminate call to an abstract function, when the left-hand side
16409 (Analyze_Loop_Statement): Improve detection of infinite loops
16411 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16412 Thomas Quinot <quinot@adacore.com>
16414 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16415 out of Analyze_Package_Declaration, because processing must be applied
16416 to package bodies as well, for deferred constants completed by pragmas.
16417 (Analyze_Package_Declaration): When the package declaration being
16418 analyzed does not require an explicit body, call Check_Completion.
16419 (May_Need_Implicit_Body): An implicit body is required when a package
16420 spec contains the declaration of a remote access-to-classwide type.
16421 (Analyze_Package_Body): If the package contains RACWs, append the
16422 pending subprogram bodies generated by exp_dist at the end of the body.
16423 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16424 Is_Abstract_Subprogram and Is_Abstract_Type.
16425 (Preserve_Full_Attributes): The full entity list is not an attribute
16426 that must be preserved from full to partial view.
16428 * sem_dist.adb (Add_RAS_Dereference_TSS):
16429 Change primitive name to _Call so it cannot clash with any legal
16430 identifier, and be special-cased in Check_Completion.
16431 Mark the full view of the designated type for the RACW associated with
16432 a RAS as Comes_From_Source to get proper view switching when installing
16433 private declarations.
16434 Provite a placeholder nested package body along with the nested spec
16435 to have a place for Append_RACW_Bodies to generate the calling stubs
16436 and stream attributes.
16438 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16439 Robert Dewar <dewar@adacore.com>
16441 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16442 that is a limited view, check the non-limited view if available.
16443 (Undefined): Refine error message for missing with of Text_IO
16444 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16445 to distinguish real missing with cases.
16446 Fix format of all missing with messages
16447 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16448 renaming as body when renamed entity is abstract.
16450 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16451 Javier Miranda <miranda@adacore.com>
16453 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16454 predicate recursive, to handle complex expressions on literals whose
16455 spurious ambiguity comes from the abstract interpretation of some
16457 (Interface_Present_In_Ancestor): Add support to concurrent record
16459 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16460 Is_Abstract_Subprogram and Is_Abstract_Type.
16462 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16463 Javier Miranda <miranda@adacore.com>
16465 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16466 dereference of a local object R created as a reference to another
16467 object O, use the access level of O.
16468 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16469 rather than local Same_Formal_Type, to check whether protected operation
16470 overrides an inherited one.
16471 (Same_Formal_Type): New predicate, used when matching signatures of
16472 overriding synchronized operations, to handle the case when a formal
16473 has a type that is a generic actual.
16474 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16475 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16476 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16477 syntactic ambiguities involving indexing of function calls that return
16479 (Abstract_Interface_List): New subprogram that returns the list of
16480 abstract interfaces associated with a concurrent type or a
16481 concurrent record type.
16482 (Interface_Present_In_Parent): New subprogram used to check if a
16483 given type or some of its parents implement a given interface.
16484 (Collect_Abstract_Interfaces): Add support for concurrent types
16485 with interface types.
16486 (Has_Abstract_Interfaces): Add support for concurrent types with
16488 (Is_Parent): New subprogram that determines whether E1 is a parent
16489 of E2. For a concurrent type its parent is the first element of its
16490 list of interface types; for other types this function provides the
16491 same result than Is_Ancestor.
16492 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16493 (Collect_Synchronized_Interfaces): Removed because the subprogram
16494 Collect_Abstract_Interfaces provides this functionality.
16495 (Collect_Abstract_Interfaces): Minor update to give support to
16496 concurrent types and thus avoid undesired code duplication.
16497 (Get_Subprogram_Entity): Handle entry calls.
16498 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16500 (Enter_Name): Do not give -gnatwh hiding warning for record component

16510 New field Exception_Label added
16511 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16512 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node

16516 can be an E_Return_Statement.
16517 (Is_Coextension): New flag for allocators.

16525 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16526 before propagating exception.
16528 2007-04-06 Olivier Hainque <hainque@adacore.com>
16530 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16531 an address always within the call instruction from a return address.
16533 2007-04-06 Olivier Hainque <hainque@adacore.com>
16534 Eric Botcazou <botcazou@adacore.com>
16536 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16537 expression with a COMPOUND_EXPR including the call instead of emitting
16538 the call directly here.
16539 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16540 high bound is constant and the slice is empty. Tidy.
16541 (tree_transform, case N_Op_Not): Handle properly the case where the
16542 operation applies to a private type whose full view is a modular type.
16543 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16544 Address_Clause, use the associated Expression as the GNAT tree
16545 representing the choice value to ensure the corresponding GCC tree is
16546 of the proper kind.
16547 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16548 instead of just the operands, as the base GCC stabilize_reference does.
16549 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16550 requested; otherwise fail.
16551 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16553 2007-04-06 Thomas Quinot <quinot@adacore.com>

16556 implementation of UI_Div.
16557 (UI_Div): Reimplement as a call to UI_Div_Rem.
16558 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16559 remainder, avoiding the cost of a multiplication and a subtraction.
16560 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16561 provides both quotient and remainder in a single computation.
16562 (UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
16563 functions for uint.
16564 (UI_Modular_Inverse): Add a note that the behaviour of this subprogram
16565 is undefined if the given n is not inversible.
16567 2007-04-06 Olivier Hainque <hainque@adacore.com>
16569 * utils2.c (known_alignment): Handle COMPOUND_EXPR, COND_EXPR and
16570 BIT_AND_EXPR. Handle also VIEW_CONVERT_EXPR, as the other conversion
16573 2007-04-06 Eric Botcazou <botcazou@adacore.com>
16574 Olivier Hainque <hainque@adacore.com>
16576 * utils.c (update_pointer_to): Make a copy of the couple of FIELD_DECLs
16577 when updating the contents of the old pointer to an unconstrained array.
16578 (end_subprog_body): Set error_gnat_node to Empty.
16579 (write_record_type_debug_info): Do not be unduly sparing with our bytes.
16580 (unchecked_convert): For subtype to base type conversions, require that
16581 the source be a subtype if it is an integer type.

16830 Valid_Conversion, to incorporate accessibility checks for arrays of
16831 anonymous access types.
16832 (Valid_Conversion): For a conversion to a numeric type occurring in an
16833 instance or inlined body, no need to check that the operand type is
16834 numeric, since this has been checked during analysis of the template.

16890 zone data and calculate the GMT offset.
16891 (__gnat_localtime_tzoff for Darwin, Free BSD, Linux, Lynx and Tru64):

17539 the parent part is a build-in-place function call, generate assignments.
17540 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17541 are build-in-place function calls.
17542 (Replace_Self_Reference): New subsidiary of
17543 Make_OK_Assignment_Statement, to replace an access attribute that is a
17544 self-reference into an access to the appropriate component of the
17545 target object. Generalizes previous mechanism to handle self-references
17546 nested at any level.
17547 (Is_Self_Referential_Init): Remove, not needed.
17548 (Is_Self_Referential_Init): New predicate to simplify handling of self
17549 referential components in record aggregates.
17550 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17551 check for presence of entity before checking for self-reference.
17552 (Has_Default_Init_Comps): Return True if a component association is a
17553 self-reference to the enclosing type, which can only come from a
17554 default initialization.
17555 (Make_OK_Assignment_Statement): If the expression is of the form
17556 Typ'Acc, where Acc is an access attribute, the expression comes from a
17557 default initialized self-referential component.
17558 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17559 that has been derived from several abstract interfaces we must also
17560 initialize the tags of the secondary dispatch tables.

17564 Javier Miranda <miranda@adacore.com>
17565 Robert Dewar <dewar@adacore.com>
17568 (Expand_Access_To_Protected_Op): If the context indicates that an access
17569 to a local operation may be transfered outside of the object, create an
17570 access to the wrapper operation that must be used in an external call.
17571 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17572 target, pass the Valid attribute applied to a floating-point prefix on
17573 to the back end without expansion.
17574 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17575 the allocated storage when it is specified by a per-object expression.
17576 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17577 Nothing to do here, the attribute has been rewritten during semantic

17581 (Find_Fat_Info): Handle case of universal real
17582 (Expand_Access_To_Protected_Op): Fix use of access to protected
17583 subprogram from inside the body of a protected entry.
17584 (Expand_Access_To_Protected_Op): Common procedure for the expansion of
17585 'Access and 'Unrestricted_Access, to transform the attribute reference
17586 into a fat pointer.
17587 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17588 subcomponent's enclosing variable is aliased with a constrained subtype.
17589 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17590 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17591 an aliased prefix must be known to be constrained in order to use True
17592 for the attribute value, and now it's possible for some aliased views
17593 to be unconstrained.
17595 2006-10-31 Robert Dewar <dewar@adacore.com>
17597 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17598 (Expand_Entity_Reference): Correct error of not handling subprogram
17599 formals in current_value processing.
17601 2006-10-31 Javier Miranda <miranda@adacore.com>

17603 Ed Schonberg <schonberg@adacore.com>
17604 Gary Dismukes <dismukes@adacore.com>
17606 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17607 register in the final list objects containing class-wide interfaces;
17608 otherwise we incorrectly register the tag of the interface in the final
17610 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17611 generate the wrapper if the parent primitive is abstract. This is
17612 required to report the correct error message.
17613 (Expand_N_Subtype_Indication): Do validity checks on range
17614 (Clean_Task_Names): If an initialization procedure includes a call to
17615 initialize a task (sub)component, indicate that the procedure will use
17616 the secondary stack.
17617 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17618 compatibility for interfacing with CPP by default.
17619 (Expand_N_Object_Declaration): Only build an Adjust call when the
17620 object's type is a nonlimited controlled type.
17621 * exp_ch3.adb: Add with and use of Exp_Ch6.
17622 (Expand_N_Object_Declaration): Check for object initialization that is a
17623 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17624 Object_Declaration to the call.
17625 (Freeze_Type): When the designated type of an RACW was not frozen at the
17626 point where the RACW was declared, validate the primitive operations
17627 with respect to E.2.2(14) when it finally is frozen.
17628 (Build_Initialization_Call,Expand_Record_Controller): Rename
17629 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17630 return-by-reference has no meaning in Ada 2005.
17631 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17632 to register tag of the immediate ancestor interfaces in the
17633 run-time structure.
17634 (Init_Secondary_Tags): Moved to the specification to allow the
17635 initialization of extension aggregates with abstract interfaces.
17636 (Build_Master_Renaming): Make public, for use by function declarations
17637 whose return type is an anonymous access type.
17638 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17639 Insert_List_Before_And_Analyze after the generation of the specs
17640 associated with null procedures.
17641 (Expand_Tagged_Root): Update documentation in its specification.
17642 (Init_Secondary_Tags): Update documentation.
17643 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17644 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17645 then generate code to inherit the contents of the dispatch table
17646 directly from the ancestor.
17647 (Expand_Record_Controller): Insert controller component after tags of
17648 implemented interfaces.
17649 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17650 create null procedure overridings when null procedures are inherited
17652 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17653 declarations for overriding null primitives inherited from interfaces.
17654 (Is_Null_Interface_Procedure): New function in
17655 Make_Null_Procedure_Specs.
17656 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17657 immediate ancestor of a tagged type is an abstract interface type we
17658 must generate the specification of the predefined primitives associated
17659 with controlled types (because the dispatch table of the ancestor is
17660 null and hence these entries cannot be inherited). This is required to
17661 elaborate well the dispatch table.

17669 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17671 (Expand_N_In): Do validity checks on range
17672 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17673 (Expand_N_Allocator): For "new T", if the object is constrained by
17674 discriminant defaults, allocate the right amount of memory, rather than
17675 the maximum for type T.
17676 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17677 when the allocator is initialized by a build-in-place call, since the
17678 allocator is already rewritten as a reference to the function result,
17679 and this prevents an unwanted duplication of the function call.
17680 Add with and use of Exp_Ch6.
17681 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17682 is a call to build-in-place function and apply
17683 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17684 untagged designated types).
17685 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17686 optimization if source or target is biased.
17687 (Expand_N_Allocator): Add comments for case of an allocator within a
17688 function that returns an anonymous access type designating tasks.
17689 (Expand_N_Allocator): apply discriminant checks for access
17690 discriminants of anonymous access types (AI-402, AI-416)

17697 * exp_ch5.ads (Expand_N_Extended_Return_Statement): New procedure.
17699 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17700 (Expand_N_Assignment_Statement): Call
17701 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17702 build-in-place function call. Currently, this can happen only for
17703 assignments that come from aggregates.
17704 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17705 in order to alleviate the upward compatibility introduced by AI-318.
17706 (Expand_N_Extended_Return_Statement): Add support for handling the
17707 return object as a build-in-place result.
17708 (Expand_Non_Function_Return): Implement simple return statements nested
17709 within an extended return.
17710 (Enable_New_Return_Processing): Turn on the new processing of return
17712 (Expand_Non_Function_Return): For a return within an extended return,
17713 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17714 (Expand_N_Extended_Return_Statement): Implement AI-318
17715 (Expand_Simple_Function_Return): Ditto.
17716 (Expand_N_If_Statement): Handle new -gnatwt warning
17717 (Expand_N_Case_Statement): Handle new -gnatwt warning
17718 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17719 a protected object.
17720 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17721 validity checking of assignments to elementary record components.
17722 (Expand_N_Return_Statement): return Class Wide types on the secondary
17723 stack independantly of their controlled status since with HIE runtimes,
17724 class wide types are not potentially controlled anymore.
17726 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17729 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17730 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17731 it expects a block, procedure, or task. The return statement will get
17732 turned into a block, and Expand_Cleanup_Actions will happen then.

17736 Bob Duff <duff@adacore.com>
17737 Gary Dismukes <dismukes@adacore.com>
17739 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17741 (Expand_Inlined_Call): Tagged types are by-reference types, and
17742 therefore should be replaced by a renaming declaration in the expanded
17743 body, as is done for limited types.
17744 (Expand_Call): If this is a call to a function with dispatching access
17745 result, propagate tag from context.
17746 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17748 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17749 build-in-place when the right-hand side of an assignment is a
17750 build-in-place function call.
17751 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17752 of the explicit dereference of the allocator to the result subtype of
17753 the build-in-place function. This is needed to satisfy type checking
17754 in cases where the caller's return object is created by an allocator for
17755 a class-wide access type and the type named in the allocator is a
17757 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17758 conversion of the reference to the declared object to the result subtype
17759 of the build-in-place function. This is needed to satisfy type checking
17760 in cases where the declared object has a class-wide type. Also, in the
17761 class-wide case, change the type of the object entity to the specific
17762 result subtype of the function, to avoid passing a class-wide object
17763 without explicit initialization to the back end.
17764 (Register_Interface_DT_Entry): Moved outside the body of
17765 Freeze_Subprogram because this routine is now public; it is called from
17766 Check_Dispatching_Overriding to handle late overriding of abstract
17767 interface primitives.
17768 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17769 adding an implicit access actual on a call to a build-in-place function.
17770 (Expand_Actuals): Test for an actual parameter that is a call to a
17771 build-in-place function and apply
17772 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17773 (Is_Build_In_Place_Function): New function to determine whether an
17774 entity is a function whose calls should be handled as build-in-place.
17775 (Is_Build_In_Place_Function_Call): New function to determine whether an
17776 expression is a function call that should handled as build-in-place.
17777 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17778 calls to build-in-place functions as the initialization of an allocator.
17779 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17780 handling calls to build-in-place functions in contexts that do not
17781 involve init of a separate object (for example, actuals of subprogram
17783 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17784 handling calls to build-in-place functions as the initialization of an
17785 object declaration.
17786 (Detect_Infinite_Recursion): Add explicit parameter Process to
17787 instantiation of Traverse_Body to avoid unreferenced warning.
17788 (Check_Overriding_Inherited_Interfaces): Removed.
17789 (Register_Interface_DT_Entry): Code cleanup.
17790 (Register_Predefined_DT_Entry): Code cleanup.
17791 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17792 inlined statements if within a transient scope.
17793 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17794 formal parameters with occurrences of actuals in inlined body, establish
17795 visibility on the proper view of the actual's subtype for the body's
17797 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17798 compatibility mode and we have an imported CPP subprogram because
17799 for now we assume that imported CPP primitives correspond with
17800 objects whose constructor is in the CPP side (and therefore we
17801 don't need to generate code to register them in the dispatch table).
17802 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17803 aligned selected component.
17804 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17805 the actual of an in-mode parameter is a type conversion.
17806 (Expand_Actuals): If the call does not come from source and the actual
17807 is potentially misaligned, let gigi handle it rather than rejecting the
17808 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17809 Class Wide types as returning by reference independantly of their
17810 controlled status since with HIE runtimes class wide types are not
17811 potentially controlled anymore.
17813 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17815 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17816 references that are private components of the protected object.

17818 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17819 instantiation to deal with warnings.

17824 2006-10-31 Robert Dewar <dewar@adacore.com>
17826 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17827 initialization of Homonym_Len.
17828 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17829 names from fully qualified name. Fixes problem of duplicate
17830 external names differing only in the presence of such a block name.
17832 2006-10-31 Thomas Quinot <quinot@adacore.com>
17833 Pablo Oliveira <oliveira@adacore.com>
17835 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17836 subprogram Ids, even if they are not yet assigned.
17837 (Build_Subprogram_Id): It is now this function that will take care of
17838 calling Assign_Subprogram_Ids if necessary.
17839 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17840 should be done only once they are assigned.
17841 (Build_From_Any_Function, case of tagged types): Add missing call to
17843 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17844 type for an RACW type.
17845 (Add_RACW_Features): When processing an RACW declaration for which the
17846 designated type is already frozen, enforce E.2.2(14) rules immediately.
17847 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17848 special reordering of controlling formals.
17850 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17851 associated stub type for an RACW type.
17853 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17855 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17856 fixed-point operations in an integer context, i.e. as operands of a
17857 conversion to an integer type, indicate that result must be rounded.
17859 2006-10-31 Robert Dewar <dewar@adacore.com>
17861 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17862 cases, pass the encoding method, since it is now required by the run
17865 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17866 assumption that Str'First = 1.
17867 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17868 it on to the Value_Wide_Wide_Character call.
17869 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17870 properly handles a string of the form quote-encoded_wide_char-quote.
17872 * s-wchcnv.adb: Minor reformatting
17874 2006-10-31 Javier Miranda <miranda@adacore.com>
17876 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17877 run-time membership test to ensure that the constructed object
17878 implements the target abstract interface.
17880 2006-10-31 Robert Dewar <dewar@adacore.com>
17882 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17883 Machine_Attribute pragma internally to implement the user pragma.
17884 Add processing for pragma Interface so that it is now completely
17885 equivalent to pragma Import.
17887 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17888 so that it can be applied to all entities, including record components
17889 and enumeration literals.
17890 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17891 priority ranges are correct, verify compatibility against task
17892 dispatching and locking policies, and if everything is correct an entry
17893 is added to the table containing priority specific dispatching entries
17894 for this compilation unit.
17895 (Delay_Config_Pragma_Analyze): Delay processing
17896 Priority_Specific_Dispatching pragmas because when processing the
17897 pragma we need to access run-time data, such as the range of
17898 System.Any_Priority.
17899 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17900 Allow pragma Unreferenced as a context item
17901 Add pragma Preelaborable_Initialization

17903 now syntactically and semantically equivalent to Import.
17904 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17905 insertion characters.
17906 Add handling for Pragma_Wide_Character_Encoding
17907 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17908 never supercedes a real restriction, and that a real restriction
17909 always supercedes a warning.
17910 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17914 Ed Schonberg <schonberg@adacore.com>
17915 Robert Dewar <dewar@adacore.com>
17917 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17918 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17919 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17921 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17922 type of the function containing a return statement, because the
17923 Return_Type field was removed. We now use the Return_Applies_To field.
17925 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17926 (Build_Task_Image_Decl): If procedure is not called from an
17927 initialization procedure, indicate that function that builds task name
17928 uses the sec. stack. Otherwise the enclosing initialization procedure
17929 will carry the indication.
17930 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17931 N_Object_Declaration instead.
17932 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17933 conditional dead code killed, and change implementation accordingly.
17934 (Insert_Actions): Add N_Return_Object_Declaration case.
17935 Correct comment to mention N_Extension_Aggregate node.
17936 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17937 attempts to save information for global variables which cannot be
17939 (Get_Current_Value_Condition): Handle conditions the other way round
17940 (constant on left). Also handle right operand of AND and AND THEN
17941 (Set_Current_Value_Condition): Corresponding changes
17942 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17943 (Get_Current_Value_Condition): Handle simple boolean operands
17944 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17945 (Get_Current_Value_Condition): If the variable reference is within an
17946 if-statement, does not appear in the list of then_statments, and does
17947 not come from source, treat it as being at unknown location.
17948 (Get_Current_Value_Condition): Enhance to allow while statements to be
17949 processed as well as if statements.
17950 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17952 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17953 of loop. This is safe now that we fixed Kill_Current_Values.
17954 (OK_To_Do_Constant_Replacement): Check whether current scope is
17955 Standard, before examining outer scopes.
17957 2006-10-31 Vincent Celier <celier@adacore.com>
17959 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17960 When True, apply VMS treatment to children of packages A, G, I and S.
17963 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17965 2006-10-31 Robert Dewar <dewar@adacore.com>
17966 Ed Schonberg <schonberg@adacore.com>

17969 (Warn_Overlay): Supply missing continuation marks in error msgs
17970 (Freeze_Entity): Add check for Preelaborable_Initialization
17972 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17974 * g-expect.adb: Add Warnings (Off) to prevent new warning
17976 * lib-xref.adb: Add handling of Last_Assignment field
17977 (Generate_Reference): Centralize handling of pragma Obsolescent here
17978 (Generate_Reference): Accept an implicit reference generated for a
17979 default in an instance.
17980 (Generate_Reference): Accept a reference for a node that is not in the
17981 main unit, if it is the generic body corresponding to an subprogram
17984 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17986 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17988 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17990 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17991 use clauses, to avoid messages on packages used to qualify, and also
17992 to avoid messages from obsolescent units.
17993 (Warn_On_Useless_Assignments): Don't generate messages for imported
17994 and exported variables.
17995 (Warn_On_Useless_Assignments): New procedure
17996 (Output_Obsolescent_Entity_Warnings): New procedure
17997 (Check_Code_Statement): New procedure
17999 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

18001 (Last_Assignment): New field for useless assignment warning
18003 2006-10-31 Olivier Hainque <hainque@adacore.com>
18005 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18006 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18008 2006-10-31 Bob Duff <duff@adacore.com>
18009 Robert Dewar <dewar@adacore.com>
18010 Ed Schonberg <schonberg@adacore.com>
18012 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18013 Ada 95 mode, because it violates the new rules for AI-318.
18015 * g-awk.ads: Use overloaded subprograms in every case where we used to
18016 have a default of Current_Session. This makes the code closer to be
18017 correct for both Ada 95 and 2005.
18019 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18020 code, relying on the fact that the compiler generates a warning
18021 instead of an error in -gnatg mode.
18023 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18024 E_Return_Statement entity kind.
18025 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18027 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18028 report an error if the reserved word abstract has been previously found.
18029 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18031 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18032 parenthesized range attribute usage
18033 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18035 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18036 in the syntax for extended_return_statement. This is not in the latest
18037 RM, but the ARG is expected to issue an AI allowing this.
18038 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18039 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18040 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18041 P_Return_Statement): Parse the new syntax for extended_return_statement.
18043 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18044 Output_End_Missing): Add error-recovery code for the new
18045 extended_return_statement syntax; that is, the new E_Return entry on
18048 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18049 limited to nonlimited, because otherwise we violate the new Ada 2005
18050 rules about returning limited types in function Create_AST_Handler in
18053 * sem.adb (Analyze): Add cases for new node kinds
18054 N_Extended_Return_Statement and N_Return_Object_Declaration.
18056 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18057 type is in the same category as type of context before applying check,
18058 to prevent anomalies in instantiations.
18059 (Resolve_Aggregate): Remove test for limited components in aggregates.
18060 It's unnecessary in Ada 95, because if it has limited components, then
18061 it must be limited. It's wrong in Ada 2005, because limited aggregates
18063 (Resolve_Record_Aggregate): Move check for limited types later, because
18064 OK_For_Limited_Init requires its argument to have been resolved.
18065 (Get_Value): When copying the component default expression for a
18066 defaulted association in an aggregate, use the sloc of the aggregate
18067 and not that of the original expression, to prevent spurious
18068 elaboration errors, when the expression includes function calls.
18069 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18070 were missing. We also didn't handle qualified expressions. Now also
18071 allow function calls. Use new common routine OK_For_Limited_Init.
18072 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18073 with space can upper case letter).
18075 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18076 Has_Static_Discriminants flag
18077 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18078 type with discriminants.
18079 (Process_Range_Expr_In_Decl): Do validity checks on range
18080 (Build_Discriminant_Constraints): Use updated form of
18081 Denotes_Discriminant.
18082 (Process_Subtype): If the subtype is a private subtype whose full view
18083 is a concurrent subtype, introduce an itype reference to prevent scope
18085 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18086 Record_Type_Declaration): The functionality of the subprograms
18087 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18088 is now performed by a single routine.
18089 (Build_Derived_Record_Type): If the type definition includes an explicit
18090 indication of limitedness, then the type must be marked as limited here
18091 to ensure that any access discriminants will not be treated as having
18092 a local anonymous access type.
18093 (Check_Abstract_Overriding): Issue a detailed error message when an
18094 abstract subprogram was not overridden due to incorrect mode of its
18096 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18097 synchronized private extension declarations. Verify that the ancestor is
18098 a limited or synchronized interface or in the generic case, the ancestor
18099 is a tagged limited type or synchronized interface and all progenitors
18100 are either limited or synchronized interfaces.
18101 Derived_Type_Declaration): Check for presence of private extension when
18102 dealing with synchronized formal derived types.
18103 Process_Full_View): Enchance the check done on the usage of "limited" by
18104 testing whether the private view is synchronized.
18105 Verify that a synchronized private view is completed by a protected or
18107 (OK_For_Limited_Init_In_05): New function.
18108 (Analyze_Object_Declaration): Move check for limited types later,
18109 because OK_For_Limited_Init requires its argument to have been resolved.
18110 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18111 in order to alleviate the upward compatibility introduced by AI-318.
18112 (Constrain_Corresponding_Record): If the constraint is for a component
18113 subtype, mark the itype as frozen, to avoid out-of-scope references to
18114 discriminants in the back-end.
18115 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18116 this subprogram against wrong sources.
18117 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18118 discriminant of limited type completed with a protected type, when the
18119 discriminant is used to constrain a private component of the type, and
18120 expansion is disabled.
18121 (Find_Type_Of_Object): Do not treat a return subtype that is an
18122 anonymous subtype as a local_anonymous_type, because its accessibility
18123 level is the return type of the enclosing function.
18124 (Check_Initialization): In -gnatg mode, turn the error "cannot
18125 initialize entities of limited type" into a warning.
18126 (OK_For_Limited_Init): Return true for generated nodes, since it
18127 sometimes violates the legality rules.
18128 (Make_Incomplete_Declaration): If the type for which an incomplete
18129 declaration is created happens to be the currently visible entity,
18130 preserve the homonym chain when removing it from visibility.
18131 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18132 inherited subprograms.
18133 (Access_Definition): If this is an access to function that is the return
18134 type of an access_to_function definition, context is a type declaration
18135 and the scope of the anonymous type is the current one.
18136 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18137 incomplete subtype to the set of private dependents of the original
18139 (Constrain_Discriminated_Type): Emit an error message whenever an
18140 incomplete subtype is being constrained.
18141 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18142 corresponding subtype of the full view of the original incomplete type.
18143 (Check_Incomplete): Properly detect invalid usage of incomplete types
18146 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18148 * g-catiio.ads, g-catiio.adb (Value): New function.

18157 Robert Dewar <dewar@adacore.com>
18159 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18160 handling executable extension manually and duplicating code.
18162 * make.adb: Implement new -S switch
18163 (Gnatmake): Use new function Osint.Executable_Name instead
18164 of handling executable extension manually.
18166 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18167 is specified, the executable name ends with this suffix.
18168 Take advantage of Osint.Executable_Name instead of duplicating code.
18170 * switch-m.adb: Recognize new gnatmake -S switch
18172 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18174 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18177 * makeusg.adb: Add line for gnatmake -S switch
18179 2006-10-31 Vincent Celier <celier@adacore.com>
18181 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18182 call it with -static-libgcc, as there are some platforms, such as
18183 Darwin, where one of these two switches is compulsory to link.
18185 2006-10-31 Vincent Celier <celier@adacore.com>
18187 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18188 instead of ADA_PROJECT_PATH, for the project path.
18189 (Gnatls): When displaying the project path directories, use host dir
18192 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18193 names in the project path, as absolute paths may correspond to
18194 multi-valued VMS logical names.
18196 2006-10-31 Vincent Celier <celier@adacore.com>
18198 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18199 absolute path name.
18200 (Locate_Regular_File): Ditto
18201 (Change_Dir): Remove, no longer used
18202 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18203 on Windows. Get it calling Get_Current_Dir.
18204 (OpenVMS): Remove imported boolean, no longer needed.
18205 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18206 (Pid_To_Integer): New function to convert a Process_Id to Integer
18208 2006-10-31 Thomas Quinot <quinot@adacore.com>
18210 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18211 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18213 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18216 2006-10-31 Robert Dewar <dewar@adacore.com>
18218 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18219 initial letter o as a zero.

18223 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18225 2006-10-31 Robert Dewar <dewar@adacore.com>
18227 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18229 (Layout_Variant_Record): Retrieve the discriminants from the entity
18230 rather than from the type definition, because in the case of a full
18231 type for a private type we need to take the discriminants from the
18233 (Layout_Component_List): When applying the Max operator to variants with
18234 a nonstatic size, check whether either operand is static and scale that
18235 operand from bits to storage units before applying Max.
18236 (Layout_Type): In VMS, if a C-convention access type has no explicit
18237 size clause (and does not inherit one in the case of a derived type),
18238 then the size is reset to 32 from 64.
18240 2006-10-31 Vincent Celier <celier@adacore.com>
18242 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18243 its file has already been loaded, according to the unit being loaded,
18244 not to the current value of Multiple_Unit_Index.
18246 2006-10-31 Thomas Quinot <quinot@adacore.com>
18247 Eric Botcazou <ebotcazou@adacore.com>

18282 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18284 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18285 Process_Body_Clauses): If the context of a body includes a use clause
18286 for P.Q then a with_clause for P in the same body is not redundant,
18287 even if the spec also has a with_clause on P.
18288 Add missing continuation mark to error msg
18289 (Build_Limited_Views): A limited view of a type is tagged if its
18290 declaration includes a record extension.
18291 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18292 node, even if the subunit has errors. This avoids malfunction by
18293 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18294 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18295 generation of obsolescent messages for with statements (cannot do
18296 this too early, or we cannot implement avoiding the messages in the
18297 case of obsolescent units withing obsolescent units).
18298 (Install_Siblings): If the with_clause is on a remote descendant of
18299 an ancestor of the current compilation unit, find whether there is
18300 a sibling child unit that is immediately visible.
18301 (Remove_Private_With_Clauses): New procedure, invoked after completing
18302 the analysis of the private part of a nested package, to remove from
18303 visibility the private with_clauses of the enclosing package
18305 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18306 now centralized in Generate_Reference.
18307 (Install_Limited_Context_Clauses): Remove superfluous error
18308 message associated with unlimited view visible through use
18309 and renamings. In addition, at the point in which the error
18310 is reported, we add the backslash to the text of the error
18311 to ensure that it is reported as a single error message.
18312 Use new // insertion for some continuation messages
18313 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18314 to create implicit with_clause for parent unit mentioned in original
18315 limited_with_clause.
18316 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18317 unit is a child unit. For ASIS queries.
18318 (Analyze_Subunit): If the subunit appears within a child unit, make all
18319 ancestor child units directly visible again.

18334 a formal object declaration with an access definition or a subtype mark
18335 with a null exclusion.
18336 (P_Generic_Association): Handle association with box, and others_choice
18337 with box, to support Ada 2005 partially parametrized formal packages.
18339 2006-10-31 Robert Dewar <dewar@adacore.com>
18340 Javier Miranda <miranda@adacore.com>
18342 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18343 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18344 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18345 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18346 private extensions.
18347 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18348 to P_Interface_Type_Definition.
18349 (P_Interface_Type_Definition): Addition of one formal to report an error
18350 if the reserved word abstract has been previously found.
18351 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18352 object renaming declaration with an access definition or subtype mark
18353 with a possible null exclusion.
18355 * par-ch9.adb: Minor error msg fix
18357 * par-load.adb: Add missing continuation mark to error msg

18375 2006-10-31 Vincent Celier <celier@adacore.com>
18377 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18378 on VMS, change "__" to '.' before checking the name.
18379 (Record_Ada_Source): Always add the source file name in the list of
18380 of sources, even if it is not the first time, as it is for another
18382 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18383 dot, instead of replacing only the first '_'.
18385 * prj-part.adb (Parse): Convert project file path to canonical form
18387 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18388 extended, the project id of the project extending it is recorded in its
18389 data, even when it has already been processed as an imported project.
18391 2006-10-31 Robert Dewar <dewar@adacore.com>
18393 * repinfo.adb (List_Entities): Don't list entities from renaming
18396 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18397 Robert Dewar <dewar@adacore.com>
18399 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18400 only a restriction warning is active for the given restriction. This is
18401 desirable because we do not want to modify code in the case where only
18403 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18404 causes overriding of real restrictions.
18405 Take advantage of new No_Restrictions constant.
18407 * raise.h: (__gnat_set_globals): Change profile.
18409 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18411 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18414 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18415 Move all the entities in obsolete package System.PolyORB_Interface to
18416 System.Partition_Interface.

18432 Gary Dismukes <dismukes@adacore.com>
18434 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18435 properly an attempt to apply Unchecked_Access to a protected operation.
18436 (OK_Self_Reference): New subprogram to check the legality of an access
18437 attribute whose prefix is the type of an enclosing aggregate.
18438 Generalizes previous mechanism to handle attribute references nested
18439 arbitrarily deep within the aggregate.
18440 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18441 can appear in an aggregate if this is a default-initialized aggregate
18442 for a self-referential type.
18443 (Resolve_Attribute, case Access): Ditto.
18444 Add support for new implementation defined attribute Stub_Type.
18445 (Eval_Attribute, case Attribute_Stub_Type): New case.
18446 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18447 (Stream_Attribute_Available): Implement using new subprogram from
18448 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18449 Has_Specified_Stream_Attribute flag.
18450 Disallow Storage_Size and Storage_Pool for access to subprogram
18451 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18452 access types of return subtypes in extended return statements. Remove
18453 accessibility checks on anonymous access types when Unchecked_Access is
18455 (Analyze_Attribute): Add support for the use of 'Class to convert
18456 a class-wide interface to a tagged type.
18457 Add support for the attribute Priority.
18458 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18459 whether the designated type is discriminated with a constrained partial
18460 view and require static matching in that case.
18461 Add local variable Des_Btyp. The Designated_Type
18462 of an access to incomplete subtype is either its non-limited view if
18463 coming from a limited with or its etype if regular incomplete subtype.
18465 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18466 Fix predicate to identify and allow cases of (expander-generated)
18467 references to tag of designated object of a RACW.
18468 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18469 non-static, and therefore cannot appear as a primary in a preelaborable
18471 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18472 Has_Read_Write_Attributes.
18473 (Has_Read_Write_Attributes): Reimplement in termes of
18474 Has_Stream_Attribute_Definition.
18475 (Missing_Read_Write_Attributes): When checking component types in a
18476 record, unconditionally call Missing_Read_Write_Attributes recursively
18477 (remove guard checking for Is_Record_Type / Is_Access_Type).
18479 2006-10-31 Robert Dewar <dewar@adacore.com>
18481 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18482 useless assignments here and conditionalize it on absence of exception
18484 (Analyze_Exception_Handlers): Small code reorganization of error
18485 detection code, for new handling of formal packages.
18487 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18488 Hristian Kirtchev <kirtchev@adacore.com>
18490 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18491 that has been constant-folded, preserve information of original tree,
18493 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18494 generated private extension declaration if the formal derived type is
18495 synchronized. Carry synchronized present over to the generated private
18497 (Validate_Derived_Type_Instance): Ensure that the actual of a
18498 synchronized formal derived type is a synchronized tagged type.
18499 (Instantiate_Formal_Package): When creating the instantiation used to
18500 validate the actual package of a formal declared without a box, check
18501 whether the formal itself depends on a prior actual.
18502 (Instantiate_Formal_Subprogram): Create new entities for the defining
18503 identifiers of the formals in the renaming declaration, for ASIS use.
18504 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18505 a renaming declaration or a subtype declaration for an actual in an
18506 instance, capture location information of declaration in generic, for
18508 (Instantiate_Formal_Package): Add comments on needed additional tests.
18509 AI-317 (partial parametrization) is fully implemented.
18510 (Validate_Private_Type_Instance): Add check for actual which
18511 must have preelaborable initialization
18512 Use new // insertion for some continuation messages
18513 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18514 Default_Expression. Add type retrieval when the declaration has an
18515 access definition. Update premature usage of incomplete type check.
18516 (Check_Access_Definition): New subsidiary routine. Check whether the
18517 current compilation version is Ada 05 and the supplied node has an
18519 (Instantiate object): Alphabetize local variables. Handle the creation
18520 of new renaming declarations with respect to the kind of definition
18521 used - either an access definition or a subtype mark. Guard against
18522 unnecessary error message in the context of anonymous access types after
18523 they have been resolved. Add check for required null exclusion in a
18524 formal object declaration.
18525 (Switch_View): A private subtype of a non-private type needs to be
18526 switched (the base type can have been switched without its private
18527 dependents because of the last branch of Check_Private_View.
18528 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18530 (Instantiate_Type): Emit an error message whenever a class-wide type of
18531 a tagged incomplete type is used as a generic actual.
18532 (Find_Actual_Type): Extend routine to handle a component type in a child
18533 unit that is imported from a formal package in a parent.
18534 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18535 agree on constrainedness, rather than checking against ultimate ancestor
18536 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18537 generic body, for navigation purposes.
18539 2006-10-31 Robert Dewar <dewar@adacore.com>
18540 Thomas Quinot <quinot@adacore.com>
18542 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18544 (New_Stream_Subprogram): When processing an attribute definition clause
18545 for a stream-oriented subprogram, record an entity node occurring at
18546 the point of clause to use for checking the visibility of the clause,
18547 as defined by 8.3(23) as amended by AI-195.
18548 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18549 New_Stream_Function and New_Stream_Procedure.
18550 (New_Stream_Function, New_Stream_Procedure): Removed.
18551 (Analyze_Attribute_Definition_Clause, case Address): Check new
18552 Alignment_Check check
18554 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18555 Javier Miranda <miranda@adacore.com>
18556 Robert Dewar <dewar@adacore.com>
18558 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18559 generate the same errors compiling under -gnatc.
18560 (Try_Object_Operation): If no candidate interpretation succeeds, but
18561 there is at least one primitive operation with the right name, report
18562 error in call rather than on a malformed selected component.
18563 (Analyze_Selected_Component): If the prefix is an incomplete type from
18564 a limited view, and the full view is available, use the full view to
18565 determine whether this is a prefixed call to a primitive operation.
18566 (Operator_Check): Verify that a candidate interpretation is a binary
18567 operation before checking the type of its second formal.
18568 (Analyze_Call): Add additional warnings for function call contexts not
18570 (Analyze_Allocator): Move the check for "initialization not allowed for
18571 limited types" after analyzing the expression. This is necessary,
18572 because OK_For_Limited_Init looks at the structure of the expression.
18573 Before analysis, we don't necessarily know what sort of expression it
18574 is. For example, we don't know whether F(X) is a function call or an
18575 indexed component; the former is legal in Ada 2005; the latter is not.
18576 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18577 were missing. We also didn't handle qualified expressions. Now also
18578 allow function calls. Use new common routine OK_For_Limited_Init.
18579 (Analyze_Type_Conversion): Do not perform some legality checks in an
18580 instance, because the error message will be redundant or spurious.
18581 (Analyze_Overloaded_Selected_Component): Do not do style check when
18582 setting an entity, since we do not know it is the right entity yet.
18583 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18584 (Analyze_Overloaded_Selected_Component): Same change
18585 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18586 since regular incomplete subtypes are transformed into corresponding
18587 subtypes of their full views.
18588 (Complete_Object_Operation): Treat name of transformed subprogram call
18589 as coming from source, for browsing purposes.
18590 (Try_Primitive_Operation): If formal is an access parameter, compare
18591 with base type of object to determine whether it is a primitive
18593 (Operator_Check): If no interpretation of the operator matches, check
18594 whether a use clause on any candidate might make the operation legal.
18595 (Try_Class_Wide_Operation): Check whether the first parameter is an
18596 access type whose designated type is class-wide.
18598 2006-10-31 Robert Dewar <dewar@adacore.com>
18599 Ed Schonberg <schonberg@adacore.com>

18603 warn on infinite loops.
18604 Add \\ to some continuation messages
18605 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18606 (Process_Bounds): If the bounds are integer literals that result from
18607 constant-folding, and they carry a user-defined type, preserve that type
18608 rather than treating this as an integer range.
18609 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18610 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18611 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18612 left hand side of assignment.
18613 (Analyze_Assignment): Add suport to manage assigments to the attribute
18614 priority of a protected object.
18615 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18616 not just identifiers.
18617 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18618 or AND THEN for possible tracking.
18619 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18620 case of while loops so we can track values in the loop body.
18622 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18623 Hristian Kirtchev <kirtchev@adacore.com>
18624 Bob Duff <duff@adacore.com>
18626 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18627 procedure cannot be a protected operation (it is a basic_declaration,
18628 not a subprogram_declaration).
18629 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18630 Subp. Add logic for entry processing.
18631 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18632 Determine whether an entry or subprogram of a protected or task type
18633 override an inherited primitive of an implemented interface.
18634 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18635 Update the actual used in calls to Check_Overriding_Indicator.
18636 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18637 generate the proper reference to the parent unit, for cross-reference.
18638 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18640 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18641 (Add_Extra_Formal): Revise procedure to allow passing in associated
18642 entity, scope, and name suffix, and handle setting of the new
18643 Extra_Formals field.
18644 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18645 pass new parameters. Add support for adding the new extra access formal
18646 for functions whose calls are treated as build-in-place.
18647 (Analyze_A_Return_Statement): Correct casing in error message.
18648 Move Pop_Scope to after Analyze_Function_Return, because an extended
18649 return statement really is a full-fledged scope. Otherwise, visibility
18650 doesn't work right. Correct use of "\" for continuation messages.
18651 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18652 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18653 the node doesn't get properly marked as analyzed.
18654 (Analyze_Subprogram_Body): If subprogram is a function that returns
18655 an anonymous access type that denotes a task, build a Master Entity
18657 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18658 proper usage of null exclusion in a result definition.
18659 (Process_Formals): Code cleanup and new error message.
18660 (Process_Formals): Detect incorrect application of null exclusion to
18662 (Conforming_Types): Handle conformance between [sub]types and itypes
18663 generated for entities that have null exclusions applied to them.
18664 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18665 base type is an access subtype. This case arrises with null exclusions.
18666 (New_Overloaded_Entity): Do not remove the overriden entity from the
18667 homonym chain if it corresponds with an abstract interface primitive.
18668 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18669 call to the synthesized predicate Is_Incomplete_Type.
18670 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18672 (Analyze_Subprogram_Declaration): Check that abstract interface
18673 primitives are abstract or null.
18674 (Analyze_Subprogram_Specification): Remove previous check for abstract
18675 interfaces because it was not complete.
18676 (Has_Interface_Formals): Removed.
18678 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18679 Javier Miranda <miranda@adacore.com>
18681 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18682 of Analyze_Package_Body, to create Itype references for anonymous
18683 access types created in the package declaration, whose designated types
18684 may have only a limited view.
18685 (Analyze_Package_Specification): For the private part of a nested
18686 package, install private_with_clauses of enclosing compilation unit if
18687 we are in its visible part.
18688 (Declare_Inherited_Private_Subprograms): Complete barrier
18689 to ensure that the primitive operation has an alias to some parent
18690 primitive. This is now required because, after the changes done for the
18691 implementation of abstract interfaces, the contents of the list of
18692 primitives has entities whose alias attribute references entities of
18693 such list of primitives.
18694 (Analyze_Package_Specification): Simplify code that handles parent units
18695 of instances and formal packages.
18696 (Uninstall_Declarations): Check the convention consistency among
18697 primitive overriding operations of a tagged record type.

18706 expected and found set right)
18707 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18708 (Analyze_Generic_Renaming): Same fix
18709 (Use_One_Package): Do not take into account the internal entities of
18710 abstract interfaces during the analysis of entities that are marked
18711 as potentially use-visible.
18712 (Find_Type): Handle the case of an attribute reference for
18713 implementation defined attribute Stub_Type (simply let the analysis of
18714 the attribute reference rewrite it).
18715 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18716 type that appears in a Use_Type clause.
18717 (Analyze_Object_Renaming): Add support for renaming of the Priority
18719 (Find_Type): In Ada 2005, a task type can be used within its own body,
18720 when it appears in an access definition.
18721 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18722 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18723 in a formal object declaration or in a subtype declaration.
18724 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18725 (Check_Null_Exclusion): New local routine to
18726 Analyze_Subprogram_Renaming. Check whether the formals and return
18727 profile of a renamed subprogram have required null exclusions when
18728 their counterparts of the renaming already impose them.
18729 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18730 Determine whether an entity is inside a generic scope.
18731 (In_Open_Scope): First pass of documentation update.
18732 (Find_Expanded_Name): Add support for shadow entities associated with
18733 limited withed packages. This is required to handle nested packages.
18734 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18735 that makes a renaming of a limited withed package illegal.

18740 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18741 Check_Overriding_Indicator.
18742 (Analyze_Task_Definition): Ditto.
18743 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18744 (Check_Overriding_Indicator): To find overridden interface operation,
18745 examine only homonyms that have an explicit subprogram declaration, not
18746 inherited operations created by an unrelated type derivation.
18747 (Check_Overriding_Indicator): When checking for the presence of "null"
18748 in a procedure, ensure that the queried node is a procedure
18750 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18751 type when the formal is an access to variable.
18752 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18753 (Analyze_Task_Type): Same addition
18754 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18762 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18763 inherited from an interface ancestor by another interface in the
18764 context of an instance as 'late'.
18765 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18766 of a call to a function that dispatches on access result.
18767 (Check_Dispatching_Operation): In case of late overriding of a primitive
18768 that covers abstract interface subprograms we register it in all the
18769 secondary dispatch tables associated with abstract interfaces.
18770 (Check_Dispatching_Call): Add check that a dispatching call is not made
18771 to a function with a controlling result of a limited type. This is a
18772 current implementation restriction.
18773 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18774 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18775 argument is an interface type that is a generic formal.
18776 (Is_Interface_Subprogram): Removed.
18777 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18778 operation, check the formals to handle the case in which it is
18779 associated with an abstract interface type.

18797 Javier Miranda <miranda@adacore.com>
18799 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
18800 subprogram type to provide better diagnostics in case of ambiguity.
18801 (Covers): Handle coverage of formal and actual anonymous access types in
18802 the context of generic instantiation.
18803 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
18804 abstract interface types; this is required to handle concurrent types
18805 with discriminants and abstract interface types.
18806 (Covers): Include type coverage of both regular incomplete subtypes and
18807 incomplete subtypes of incomplete type visibles through a limited with

18821 qualification from an expression. There are numerous places where this
18822 ought to be used, but we currently only deal properly with zero or one
18824 (In_Instance); The analysis of the actuals in the instantiation of a
18825 child unit is not within an instantiation, even though the parent
18826 instance is on the scope stack.
18827 (Safe_To_Capture_Value): Exclude the case of variables that are
18829 (Check_Obsolescent): Removed
18830 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

18850 objects to handle the Ada 2005 case, where aliasedness no longer implies
18851 that the object is constrained. In particular, for dereferenced names,

18908 (N_Extended_Return_Statement): New node for extended_return_statement
18910 (N_Return_Object_Declaration): New node for part of

19595 we must pass the work to the expander to generate the required code to
19596 evaluate the conversion at run-time.
19597 (Resolve_Equality_Op): Do not apply previous

20272 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20273 were not always properly handled previously.
20274 Since we are changing the tree format anyway, also get rid of the
20275 junk obsolete Immediate_Errors flag.
20276 (Tree_Read): Change the way of reading Tree_Version_String - now we
20277 read the version string from the tree even if its length is not the
20278 same as the length of the version string computed from Gnatvsn.
20279 (Search_Directory_Present): New Boolean flag for the compiler.
20280 Define Tree_Version_String as a dynamic string.
20281 (Default_Stack_Size): new variable, used to handle switch -d.
20284 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20285 only for main unit.
20286 Add pragma Ada_2005 (synonym for Ada_05)
20287 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20288 were not always properly handled previously.
20290 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20291 explicit Ada_95 to Ada_2005.
20293 2006-02-13 Javier Miranda <miranda@adacore.com>
20294 Robert Dewar <dewar@adacore.com>
20295 Ed Schonberg <schonberg@adacore.com>
20297 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20298 against errors in the source program: a private types for which the
20299 corresponding full type declaration is missing and pragma CPP_Virtual
20301 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20302 (Is_Known_Null): New flag
20303 (Has_Pragma_Pure): New flag
20304 (No_Return): Present in all entities, set only for procedures
20305 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20306 explicitly declared limited.
20307 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20308 entities. Only used for component marked Is_Tag. If present it stores
20309 the Offset_To_Top function used to provide this value in tagged types
20310 whose ancestor has discriminants.
20312 * exp_ch2.adb: Update status of new Is_Known_Null flag
20314 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20316 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20317 the categorization sense if Is_Pure was set by pragma Pure_Function.
20319 2006-02-13 Quentin Ochem <ochem@adacore.com>
20320 Olivier Hainque <hainque@adacore.com>
20322 * bindusg.adb: Updated documentation for -d and -D switches.
20324 * raise.h (__gnat_set_globals): added new parameter for
20325 Default_Stack_Size.
20327 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20328 (__gnat_handle_vms_condition): Adjust context before raise.
20329 (__gnat_install_handler): Restore the global vector setup for GCC
20330 versions before 3.4, as the frame based circtuitry is not available
20332 (__gnat_set_globals): added a parameter default_stack_size
20333 (__gl_default_stack_size): new variable.
20335 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20337 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20338 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20339 does not exist in the Ada RM.
20340 (Compatible_Int_Bounds): Determine whether two integer range bounds
20341 are of equal length and have the same start and end values.
20342 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20343 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20344 aggregate when it is part of an object declaration.
20345 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20346 constrains discriminants of its parent, add explicitly the discriminant
20347 constraints of the ancestor by retrieving them from the
20348 stored_constraint of the parent.
20350 2006-02-13 Robert Dewar <dewar@adacore.com>
20352 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20353 attribute Mechanism_Code is applied to renamed subprogram, modify
20354 prefix to point to base subprogram.
20355 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20357 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20358 renamed subprograms so that the front-end must replace the prefix
20361 2006-02-13 Javier Miranda <miranda@adacore.com>
20362 Gary Dismukes <dismukes@adacore.com>
20364 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20365 availability of RE_Interface_Tag.
20366 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20367 (Freeze_Record_Type): Do not generate the tables associated with
20368 timed and conditional dispatching calls through synchronized
20369 interfaces if compiling under No_Dispatching_Calls restriction.
20370 When compiling for Ada 2005, for a nonabstract
20371 type with a null extension, call Make_Controlling_Function_Wrappers
20372 and insert the wrapper function declarations and bodies (the latter
20373 being appended as freeze actions).
20374 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20375 predefined primitives associated with timed and conditional
20376 dispatching calls through synchronized interfaces if we are
20377 compiling under No_Dispatching_Calls.
20378 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20379 service is available before generating a call.
20380 (Make_Controlling_Function_Wrappers): New procedure.
20381 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20382 access-to-limited-interfaces because they can be used to reference
20383 tasks that implement such limited interface.
20384 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20385 procedure spec and body of the Offset_To_Top function that is generated
20386 when the parent of a type with discriminants has secondary dispatch
20388 (Init_Secondary_Tags): Handle the case in which the parent of the type
20389 containing secondary dispatch tables has discriminants to generate the
20390 correct arguments to call Set_Offset_To_Top.
20391 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20393 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20394 Add Wide_[Wide_]Expanded_Name.
20395 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20396 the same functionality of Get_Prim_Op_Address but applied to predefined
20397 primitive operations because the pointers to the predefined primitives
20398 are now saved in a separate table.
20399 (Parent_Size): Modified to get access to the separate table of primitive
20400 operations or the parent type.
20401 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20402 functionality of Set_Prim_Op_Address but applied to predefined primitive
20404 (Set_Signature): New subprogram used to store the signature of a DT.
20405 (Displace): If the Offset_To_Top value is not static then call the
20406 function generated by the expander to get such value; otherwise use
20407 the value stored in the table of interfaces.
20408 (Offset_To_Top): The type of the actual has been changed to Address to
20409 give the correct support to tagged types with discriminants. In this
20410 case this value is stored just immediately after the tag field.
20411 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20412 offset_to_top value is static and hence pass this value to the run-time
20413 to store it in the table of interfaces, or else if this value is dynamic
20414 and then pass to the run-time the address of a function that is
20415 generated by the expander to provide this value for each object of the
20418 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20419 (Default_Prim_Op_Count): New entity
20420 (Get_Predefined_Prim_Op_Address): New entity
20421 (Set_Predefined_Prim_Op_Address): New entity
20422 (RE_Set_Signature): New entity
20424 2006-02-13 Thomas Quinot <quinot@adacore.com>
20425 Ed Schonberg <schonberg@adacore.com>
20427 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20428 Make_Adjust_Call done for a newly-allocated object.
20430 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20431 in a subprogram are wrapped in a cleanup block, indicate that the
20432 subprogram contains an inner block with an exception handler.
20433 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20434 Adjust call is for a newly-allocated object. In that case we must not
20435 assume that the finalization list chain pointers are correct (since they
20436 come from a bit-for-bit copy of the original object's pointers) so if
20437 the attach level would otherwise be zero (no change), we set it to 4
20438 instead to cause the pointers to be reset to null.
20440 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20441 reset chain pointers to null.
20443 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20445 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20446 string, and the context requires a loop for the assignment (e.g.
20447 because the left-hand side is packed), generate a unique name for the
20448 temporary that holds the string, to prevent spurious name clashes.
20450 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20451 Javier Miranda <miranda@adacore.com>
20452 Robert Dewar <dewar@adacore.com>
20453 Gary Dismukes <dismukes@adacore.com>
20455 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20456 return unconstrained arrays.
20458 (Expand_Call): An indirect call through an access parameter of a
20459 protected operation is not a protected call.
20460 Add circuit to raise CE in Ada 2005 mode following call
20461 to Raise_Exception.
20462 (Register_DT_Entry): Do nothing if
20463 the run-time does not give support to abstract interfaces.
20464 (Freeze_Subprogram): In case of dispatching operations, do not generate
20465 code to register the operation in the dispatch table if the source
20466 is compiled with No_Dispatching_Calls.
20467 (Register_Predefined_DT_Entry): Generate code that calls the new
20468 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20469 Set_Prim_Op_Address.
20471 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20472 on array assignments if the right-hand side is a function call that has
20473 been inlined. Check is performed on the assignment in the block.
20474 (Process_Bounds): If bounds and range are overloaded, apply preference
20475 rule for root operations to disambiguate, and diagnose true ambiguity.
20476 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20477 a tag-indeterminate right-hand side even when Expander_Active is True.
20478 Needed to ensure that dispatching calls to T'Input are allowed and
20479 get the tag of the target class-wide object.
20481 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20482 an inherited primitive operation that already overrides several
20483 abstract interface primitives. For transitivity, the new entity must
20484 also override all the abstract interface primitives covered by the
20485 inherited overriden primitive.
20486 Emit warning if new entity differs from homograph in same scope only in
20487 that one has an access parameter and the other one has a parameter of
20488 a general access type with the same designated type, at the same
20489 position in the signature.
20490 (Make_Inequality_Operator): Use source locations of parameters and
20491 subtype marks from corresponding equality operator when creating the
20492 tree structure for the implicit declaration of "/=". This does not
20493 change anything in behaviour except that the decoration of the
20494 components of the subtree created for "/=" allows ASIS to get the
20495 string images of the corresponding identifiers.
20496 (Analyze_Return_Statement): Remove '!' in warning message.
20497 (Check_Statement_Sequence): Likewise.
20498 (Analyze_Subprogram_Body): For an access parameter whose designated type
20499 is an incomplete type imported through a limited_with clause, use the
20500 type of the corresponding formal in the body.
20501 (Check_Returns): Implicit return in No_Return procedure now raises
20502 Program_Error with a compile time warning, instead of beging illegal.
20503 (Has_Single_Return): Function returning unconstrained type cannot be
20504 inlined if expression in unique return statement is not an identifier.
20505 (Build_Body_To_Inline): It is possible to inline a function call that
20506 returns an unconstrained type if all return statements in the function
20507 return the same local variable. Subsidiary procedure Has_Single_Return
20508 verifies that the body conforms to this restriction.
20510 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20511 same type, and one of them is of an anonymous access type, convert
20512 the other operand to it, so that this is a valid binary operation for
20514 (Resolve_Type_Conversion): Handle subtypes of protected types and
20515 task types when accessing to the corresponding record type.
20516 (Resolve_Allocator): Add '\' in 2-line warning message.
20517 Remove '!' in warning message.
20518 (Resolve_Call): Add '\' in 2-line warning message.
20519 (Valid_Conversion): Likewise.
20520 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20521 resulting type may be an access type with an implicit dereference.
20522 Obtain the proper component from the designated type.
20523 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20524 given by an expanded name with prefix Standard, when the operands are
20525 of an anonymous access type.
20526 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20527 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20528 prefix of the expression is not of an incomplete type. Allows full
20529 diagnoses of all semantic errors.
20530 (Resolve_Actuals): If the actual is an allocator whose directly
20531 designated type is a class-wide interface we build an anonymous
20532 access type to use it as the type of the allocator. Later, when
20533 the subprogram call is expanded, if the interface has a secondary
20534 dispatch table the expander will add a type conversion to force
20535 the displacement of the pointer.
20536 (Resolve_Call): If a function that returns an unconstrained type is
20537 marked Inlined_Always and inlined, the call will be inlined and does
20538 not require the creation of a transient scope.
20539 (Check_Direct_Boolean_Op): Removed
20540 (Resolve_Comparison_Op): Remove call to above
20541 (Resolve_Equality_Op): Remove call to above
20542 (Resolve_Logical_Op): Inline above, since this is only call.
20543 (Valid_Conversion): Handle properly conversions between arrays of
20544 convertible anonymous access types.
20547 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20548 the literal in an unchecked conversion, because GCC 4.x needs a static
20549 value for a string bound.
20551 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20552 Hristian Kirtchev <kirtchev@adacore.com>
20554 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20555 components of the corresponding record, take into account component
20556 definitions that are access definitions.
20557 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20558 procedure is not considered a dispatching call and will be expanded
20561 2006-02-13 Javier Miranda <miranda@adacore.com>
20563 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20564 controlling argument of the dispatching call is an abstract interface
20565 class-wide type then we use it directly.
20566 Check No_Dispatching_Calls restriction.
20567 (Default_Prim_Op_Position): Remove the code that looks for the last
20568 entity in the list of aliased subprograms. This code was wrong in
20570 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20571 when the source is compiled with the No_Dispatching_Calls restriction.
20572 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20573 if we are compiling with restriction No_Dispatching_Calls.
20574 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20575 subprograms if we are compiling under No_Dispatching_Calls restriction.
20576 (Make_DT): Generate a dispatch table with a single dummy entry if
20577 we are compiling with the No_Dispatching_Calls restriction. In
20578 addition, in this case we don't generate code that calls to the
20579 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20580 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20581 of this subprogram if compiling with the No_Dispatching_Calls
20583 (Expand_Type_Conversion): Instead of using the actual parameter,
20584 the argument passed as parameter to the conversion function was
20585 erroneously referenced by the expander.
20586 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20587 Set_Predefined_Primitive_Op_Address and Set_Signature.
20588 (Expand_Dispatching_Call): Generate call to
20589 Get_Predefined_Prim_Op_Address for predefined primitives.
20590 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20591 predefined primitives.
20592 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20593 primitives we reserve one dummy entry to ensure that the tag does not
20594 point to some memory that is associated with some other object. In
20595 addition, remove all the old code that generated the assignments
20596 associated with the signature of the dispatch table and replace them
20597 by a call to the new subprogram Set_Signature.
20598 (Set_All_DT_Position): Change the algorithm because now we have a
20599 separate dispatch table associated with predefined primitive operations.
20600 (Expand_Interface_Conversion): In case of non-static offset_to_top
20601 add explicit dereference to get access to the object after the call
20602 to displace the pointer to the object.
20603 (Expand_Interface_Thunk): Modify the generation of the actual used
20604 in the calls to the run-time function Offset_To_Top to fulfil its
20606 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20608 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20610 * exp_dist.adb (Copy_Specification): For access parameters, copy
20611 Null_Exclusion flag, which will have been set for stream subprograms
20614 2006-02-13 Pascal Obry <obry@adacore.com>
20616 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20617 previous implementation was using the C runtime spawnve routine but
20618 the corresponding wait was using directly the Win32 API. This was
20619 causing some times a lock when waiting for an event using
20620 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20621 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20622 API fixes this problem.
20624 2006-02-13 Robert Dewar <dewar@adacore.com>
20626 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20629 2006-02-13 Thomas Quinot <quinot@adacore.com>

20633 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20634 array reference that is an explicit dereference, mark the converted
20635 (packed) array reference as analyzed to prevent a forthcoming
20636 reanalysis from resetting its type to the original (non-packed) array
20639 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20640 Javier Miranda <miranda@adacore.com>
20641 Eric Botcazou <ebotcazou@adacore.com>
20643 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20644 Is_Predefined_Primitive_Operation): When
20645 searching for the predefined equality operator, verify that operands
20646 have the same type.
20647 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20648 for the last entity in the list of aliased subprograms. This code
20649 was wrong in case of renamings.
20650 (Set_Renamed_Subprogram): New procedure
20651 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20652 Exp_Type constant computed when entering this subprogram.
20653 (Known_Null): New function
20654 (OK_To_Do_Constant_Replacement): New function
20655 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20656 (Side_Effect_Free): An attribute reference 'Input is not free of
20657 side effect, unlike other attributes that are functions. (from code
20659 (Remove_Side_Effects): Expressions that involve packed arrays or records
20660 are copied at the point of reference, and therefore must be marked as
20661 renamings of objects.
20662 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20663 not a dispatching operation.
20666 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20667 elementary types in all cases.
20669 2006-02-13 Javier Miranda <miranda@adacore.com>
20671 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20672 task types when accessing to the corresponding record type.
20673 Remove '!' in warning message.
20675 2006-02-13 Olivier Hainque <hainque@adacore.com>
20677 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20678 to avoid useless and space inefficient overalignments on targets where
20679 Max_Alignment is larger than 16.
20681 2006-02-13 Pascal Obry <obry@adacore.com>
20683 * g-catiio.adb (Sec_Number): New type used to compute the number of
20684 seconds since 1-1-1970.
20685 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20686 negative numbers (years, months...) it is better to have a Natural here.
20688 (Image) [Number]: Change parameter from Long_Integer to Number.
20689 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20690 overflow for dates past year 2038.
20692 2006-02-13 Matthew Heaney <heaney@adacore.com>
20694 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20697 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20699 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20701 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20702 finalization can occur normally.
20704 2006-02-13 Vincent Celier <celier@adacore.com>
20706 * gnatcmd.adb (Rules_Switches): New table
20707 (Add_To_Rules_Switches): New procedure
20708 (GNATCmd): For command CHECK, put all options following "-rules" in the
20709 Rules_Switches table. Append these -rules switches after the -cargs
20712 2006-02-13 Robert Dewar <dewar@adacore.com>
20714 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20715 These two cases were generating incorrect output, and if this unit
20716 was built with checks on, generated a discriminant mismatch constraint
20719 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20720 Robert Dewar <dewar@adacore.com>
20722 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20723 view is an array type, indicate the component type as well, for
20724 navigation purposes.
20725 (Generate_Reference): Don't consider array ref on LHS to be a case

20727 Do not give Ada 2005 warning except on real reference.
20729 2006-02-13 Vincent Celier <celier@adacore.com>
20731 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20732 main source, add switch -mdebug-main=_ada_ so that the executable can
20733 be debugged by the standard VMS debugger.
20734 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20735 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20736 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20737 of the last source, as the binding and linking phases are never
20739 Set all executable obsolete when rebuilding a library.
20741 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20744 2006-02-13 Javier Miranda <miranda@adacore.com>
20747 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20748 code to improve the error message reported when the program has
20749 declarations of abstract interface types and it is not compiled with
20750 the -gnat05 switch.
20751 (P_Access_Definition): Reorganize the code to improve the error
20752 message reported when the new Ada 2005 syntax for anonymous
20753 access types is used and the program is not compiled with the

20776 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20777 unknown, use the location of the project to report the error.
20778 (When_No_Sources): New global variable
20779 (Report_No_Ada_Sources): New procedure
20780 (Check): New parameter When_No_Sources. Set value of global variable

20783 (Get_Sources_From_File): Ditto
20784 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20787 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20788 Call Prj.Proc.Process with parameter When_No_Sources.
20790 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20791 Call Recursive_Check with parameter When_No_Sources.

20806 When removing nodes (attributes Source_Dirs, Source_Files,
20807 Source_List_File and package Naming), save the comments and attach the
20808 saved comments to the newly created nodes.
20809 Do not add a with clause for the naming package if one already exists.

20818 aliased entities to look for the overriden abstract interface
20820 (Is_Interface_Subprogram): Complete documentation.
20821 (Check_Dispatching_Operation): Do not generate code to register the
20822 operation in the dispatch table if the source is compiled with
20823 restriction No_Dispatching_Calls.

20825 No_Return procedure with procedure that is not No_Return
20826 (Check_Dispatching_Call): Suppress the check for an abstract operation
20827 when the original node of an actual is a tag-indeterminate attribute
20828 call, since the attribute, which must be 'Input, can never be abstract.
20829 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20830 call to the Input attribute (even when rewritten).
20831 (Propagate_Tag): Augment comment to indicate the possibility of a call
20832 to an Input attribute.
20834 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20844 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20846 2006-02-13 Javier Miranda <miranda@adacore.com>
20848 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20849 handles default-initialized components to keep separate the management
20850 of this feature but also avoid the unrequired resolution and
20851 expansion of components that do not have partially initialized
20853 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20854 (Check_Bounds): Likewise.
20855 (Check_Length): Likewise.
20857 2006-02-13 Javier Miranda <miranda@adacore.com>
20858 Ed Schonberg <schonberg@adacore.com>
20860 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20861 abstract interface type call analyze_and_resolve to expand the type
20862 conversion into the corresponding displacement of the
20863 reference to the base of the object.
20864 (Eval_Attribute, case Width): For systems where IEEE extended precision
20865 is supported, the maximum exponent occupies 4 decimal digits.
20866 (Accessibility_Message): Add '\' in 2-line warning message.
20867 (Resolve_Attribute): Likewise.
20868 (case Attribute_Access): Significantly revise checks
20869 for illegal access-to-subprogram Access attributes to properly enforce
20870 the rules of 3.10.2(32/2).
20871 Diagnose use of current instance with an illegal attribute.
20873 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20875 (Enclosing_Generic_Unit): New function to return a node's innermost
20876 enclosing generic declaration node.
20877 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20878 (Type_Access_Level): The accessibility level of anonymous acccess types
20879 associated with discriminants is that of the current instance of the
20880 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20881 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20882 (Kill_Current_Values_For_Entity): New function
20883 (Enter_Name): Change formal type to Entity_Id
20885 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>

20889 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20890 Analyze_Compilation_Unit.
20891 Detect and warn on redundant with clauses detected in a package spec
20892 and/or body when -gnatwr is used.
20893 (Analyze_Context): Analyze config pragmas before other items
20894 (Install_Context_Items): Don't analyze config pragmas here
20895 (Install_Limited_Withed_Unit): Set limited entity of package in
20896 with_clause so that cross-reference information or warning messages on
20897 unused packages can be properly generated
20898 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20899 has Error_Posted set. Prevent infinite loops in illegal programs.
20900 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20901 to the point of the error test requiring the current unit to be private.
20902 This ensures that private with clauses are not exempted from the basic
20903 checking for being a descendant of the same library unit parent as a
20904 withed private descendant unit.
20905 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20906 handle private with clauses properly, as well as to account for cases
20907 where the withed unit is a public descendant of a private ancestor
20908 (in which case the current unit must be a descendant of the private
20909 ancestor's parent). The spec comments were updated accordingly. Also,
20910 the old error message in this subprogram was replaced with error
20911 messages that mirror the errors tested and reported by
20912 Check_Private_Child_Unit.
20913 Parameter and variable names improved for readability.
20914 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20915 private as the precondition for calling
20916 Check_Private_Limited_Withed_Unit since that subprogram has been
20917 revised to test public units as well as private units.

20922 Javier Miranda <miranda@adacore.com>
20924 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20925 that Scope_Stack.First = 1.
20926 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20927 were not always properly handled previously.
20928 (Formal_Entity): Complete rewrite, to handle properly some complex case
20929 with multiple levels of parametrization by formal packages.
20930 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20931 to the corresponding derived type declaration for proper semantics.
20933 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20934 (Check_Component): Enforce restriction on components of
20935 unchecked_unions: a component in a variant cannot contain tasks or
20937 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20939 Add pragma Ada_2005 (synonym for Ada_05)
20940 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20941 were not always properly handled previously.
20942 Document that pragma Propagate_Exceptions has no effect
20943 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20944 (Set_Convention_From_Pragma): Check that if a convention is
20945 specified for a dispatching operation, then it must be
20946 consistent with the existing convention for the operation.
20947 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20948 longer required to specify an vtable-ptr component in the record. For
20949 compatibility reasons we leave the support for the previous definition.
20950 (Analyze_Pragma, case No_Return): Allow multiple arguments
20952 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20953 non-overrideen inherited operation with a controlling result as
20954 illegal only its implicit declaration comes from the derived type
20955 declaration of its result's type.
20956 (Check_Possible_Deferred_Completion): Relocate the object definition
20957 node of the subtype indication of a deferred constant completion rather
20958 than directly analyzing it. The analysis of the generated subtype will
20959 correctly decorate the GNAT tree.
20960 (Record_Type_Declaration): Check whether this is a declaration for a
20961 limited derived record before analyzing components.
20962 (Analyze_Component_Declaration): Diagnose record types not explicitly
20963 declared limited when a component has a limited type.
20964 (Build_Derived_Record_Type): Code reorganization to check if some of
20965 the inherited subprograms of a tagged type cover interface primitives.
20966 This check was missing in case of a full-type associated with a private
20968 (Constant_Redeclaration): Check that the subtypes of the partial and the
20969 full view of a constrained deferred constant statically match.
20970 (Mentions_T): A reference to the current type in an anonymous access
20971 component declaration must be an entity name.
20972 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20973 class_wide type to refer to full type, not to the incomplete one.
20974 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20975 available. Required to give support to the certified run-time.
20976 (Analyze_Component_Declaration): In case of anonymous access components
20977 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20978 (Process_Discriminants): For an access discriminant, use the
20979 discriminant specification as the associated_node_for_itype, to
20980 simplify accessibility checks.
20982 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20983 Javier Miranda <miranda@adacore.com>
20985 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20986 abstract interpretations on an operator, remove interpretations that
20987 yield Address or a type derived from it, if one of the operands is an
20989 (Try_Object_Operation.Try_Primitive_Operation,
20990 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20991 location when creating the new reference to a primitive or class-wide
20992 operation as a part of rewriting a subprogram call.
20993 (Try_Primitive_Operations): If context requires a function, collect all
20994 interpretations after the first match, because there may be primitive
20995 operations of the same type with the same profile and different return
20996 types. From code reading.
20997 (Try_Primitive_Operation): Use the node kind to choose the proper
20998 operation when a function and a procedure have the same parameter
21000 (Complete_Object_Operation): If formal is an access parameter and prefix
21001 is an object, rewrite as an Access reference, to match signature of
21002 primitive operation.
21003 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21004 by an expanded name with prefix Standard, when the operands are of an
21005 anonymous access type.
21006 (Remove_Abstract_Operations): If the operation is abstract because it is
21007 inherited by a user-defined type derived from Address, remove it as
21008 well from the set of candidate interpretations of an overloaded node.
21009 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21012 2006-02-13 Bob Duff <duff@adacore.com>
21014 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21015 redundant use clauses.
21016 In particular, if the scope of two use clauses overlaps, but one is not
21017 entirely included in the other, we should not warn. This can happen
21018 with nested packages.
21019 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21020 reported errors. The bug was reported when the compiler was built
21021 with assertions enabled.
21022 (Find_Type): If the node is a 'Class reference and the prefix is a
21023 synchronized type without a corresponding record, return the type
21026 2006-02-13 Javier Miranda <miranda@adacore.com>
21028 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21029 if this is the full-declaration associated with a private declaration
21030 that implement interfaces, then the private type declaration must be
21032 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21033 as aliased. The use of the 'access attribute is not available for such
21034 object (for this purpose the object should be explicitly marked as
21035 aliased, but being an anonymous type this is not possible).
21037 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21038 Robert Dewar <dewar@adacore.com>
21040 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21041 compilation unit is an elaboration scope.
21042 (Add_Task_Proc): Add '\' in 2-line warning message.
21043 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21045 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21046 Javier Miranda <miranda@adacore.com>
21048 * sem_type.adb (Write_Overloads): Improve display of candidate
21050 (Add_One_Interp): Do not add to the list of interpretations aliased
21051 entities corresponding with an abstract interface type that is an
21052 immediate ancestor of a tagged type; otherwise we have a dummy
21053 conflict between this entity and the aliased entity.
21054 (Disambiguate): The predefined equality on universal_access is not
21055 usable if there is a user-defined equality with the proper signature,
21056 declared in the same declarative part as the designated type.
21057 (Find_Unique_Type): The universal_access equality operator defined under
21058 AI-230 does not cover pool specific access types.
21059 (Covers): If one of the types is a generic actual subtype, check whether
21060 it matches the partial view of the other type.
21062 2006-02-13 Thomas Quinot <quinot@adacore.com>
21064 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21065 line. This is necessary to allow In_Extended_Main_Unit to provide
21066 correct results for itypes while writing out expanded source.
21067 (Close_File): No need to update the source_index_table here since it's
21068 now done for each line.
21070 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21071 Robert Dewar <dewar@adacore.com>
21073 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21074 preserve the source unit where the itype is declared, and prevent a
21076 (Note_Implicit_Run_Time_Call): New procedure
21077 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21080 * sprint.ads: Document use of $ for implicit run time routine call
21082 2006-02-13 Quentin Ochem <ochem@adacore.com>
21084 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21087 2006-02-13 Bob Duff <duff@adacore.com>
21089 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21090 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21091 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21092 raise Constraint_Error.
21094 * s-vallli.adb (Scan_Long_Long_Integer): Call
21095 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21096 do not scan leading blanks and sign twice.
21097 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21098 raise Constraint_Error.
21100 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21101 Scan_Long_Long_Unsigned): Split out most of the processing from
21102 Scan_Long_Long_Unsigned out into
21103 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21104 This prevents scanning leading blanks and sign twice.
21105 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21108 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21109 out most of the processing from Scan_Unsigned out into
21110 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21111 This prevents scanning leading blanks and sign twice.
21113 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21114 use with Modular'Value attribute.
21115 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21313 * a-taster.ads, a-taster.adb: New files.
21315 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21316 link to the version that does nothing. This way the task termination

21318 because of an unhandled exception.
21320 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21321 handler because of an unhandled exception.
21323 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21334 in charge of finalizing the global list for controlled objects.
21335 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21336 instead for handling run-time termination in a more flexible way.
21337 (Adafinal_NT): This new procedure will take care of finalizing the
21338 global list for controlled objects if needed, but no tasking
21341 * s-tarest.adb (Task_Lock): Do not try to lock again the
21342 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21343 some run-time operations.
21344 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21345 until all nested locks have been released.
21346 (Task_Wrapper): Call the fall-back task termination handler. It
21347 applies to all tasks but the environment task.
21348 (Finalize_Global_Tasks): Add the call for the task termination
21349 procedure for the environment task.
21350 (Task_Wrapper): suppress warnings around declaration of

21354 moved to the Common_ATCB record.
21355 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21356 Common_ATCB record.

21358 Common_ATCB record.
21360 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21361 Fall_Back_Handler, and Specific_Handler.

21364 defined in Ada.Task_Termination, to avoid circular dependencies.
21365 (Termination_Handler): Redefine this type here, alredy defined in
21366 Ada.Task_Termination, for avoiding circular dependencies.
21367 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21368 for storing task termination handlers. In addition,
21369 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21370 Common_ATCB because it is used by both the regular and the restricted
21372 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21373 Common_ATCB because it is used by both the regular and the restricted
21375 (Common_ATCB): Added a dynamic task analyzer field.

21380 tasks but the environment task.
21381 (Finalize_Global_Tasks): Call the task termination procedure for the
21382 environment task. The call to Finalize_Global_List is now performed
21383 using the soft links mechanism.
21384 (Task_Wrapper): added dynamic stack analysis.
21386 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21387 potentially blocking operations has been moved from
21388 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21389 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21390 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21391 this run-time check.
21393 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21394 of task termination procedure.
21395 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21437 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21438 to the specification because the frontend generates code that uses this
21440 (Set_Interface_Table): Add missing assertion.
21441 Update documentation describing the run-time structure.
21442 (Displace): New subprogram that displaces the pointer to the object
21443 to reference one of its secondary dispatch tables.
21444 (IW_Membership): Modified to use the new table of interfaces.
21445 (Inherit_TSD): Modified to use the new table of interfaces.
21446 (Register_Interface_Tag): Use the additional formal to fill the
21447 contents of the new table of interfaces.
21448 (Set_Interface_Table): New subprogram that stores in the TSD the

21463 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21464 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21465 record component containing the tag of the secondary dispatch table we
21466 have to use the Offset_To_Top run-time function to get this information;
21467 otherwise if the pointer to the base of the object has been displace
21468 we get a wrong value if we use the 'position attribute.
21470 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21471 all the calls to Expand_Interface_Thunk.

21475 ensure that the interfaces implemented by the ancestors are placed
21476 at the header of the generated list.
21477 (Expand_Interface_Conversion): Handle the case in which the displacement
21478 associated with the interface conversion is not statically known. In
21479 this case we generate a call to the new run-time subprogram Displace.

21481 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21482 Get_Tagged_Kind and Set_Tagged_Kind.

21490 secondary dispatch table respectively of a tagged type.
21492 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

21506 RE_TK_Tagged, RE_TK_Task.
21508 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21509 Init_Secondary_Tags_Internal to allow its use with interface types and
21510 also to generate the code for the new additional actual required
21511 by Set_Offset_To_Top.
21512 (Build_Init_Statements): In case of components associated with abstract
21513 interface types there is no need to generate a call to its IP.
21514 (Freeze_Record_Type): Generate Select Specific Data tables only for
21516 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21517 the bodies and specifications of the predefined primitive operations
21518 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21519 for concurrent types.

21524 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21525 properly protected objects and attach handler in the case of the
21526 restricted profile.
21527 Move embeded package Select_Expansion_Utilities into a separate external

21539 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21540 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21541 about the use and expansion of SAVE_EXPRs in the various possible
21542 renaming handling cases.
21543 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21544 abusing DECL_FCONTEXT.

21641 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21642 and the assignment to a class-wide object, before the assignment we
21643 generate a run-time check to ensure that the tag of the Target is
21644 covered by the tag of the source.

21709 copied component does not have a known static Esize, then reset
21710 the size and positional fields of the new component.
21711 (Analyze_Component_Declaration): A limited component is
21712 legal within a protected type that implements an interface.
21713 (Collect_Interfaces): Do not add to the list the interfaces that
21714 are implemented by the ancestors.
21715 (Derived_Type_Declaration): If the parent of the full-view is an
21716 interface perform a transformation of the tree to ensure that it has
21717 the same parent than the partial-view. This simplifies the job of the
21718 expander in order to generate the correct object layout, and it is
21719 needed because the list of interfaces of the full-view can be given in
21721 (Process_Full_View): The parent of the full-view does not need to be
21722 a descendant of the parent of the partial view if both parents are
21724 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21725 "limited" the parent must be a limited type.

21737 lists of interfaces constitute a set equality. If not, the first
21738 differing interface is returned.
21739 (Process_Full_View): Improve the check for the "no hidden interface"
21740 rule as defined by AI-396.

21799 available user-specified stream attributes on limited parameters to
21800 also test the type directly rather than only its underlying type (for
21801 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21802 attributes are visible at the point of the subprogram declaration.
21803 For Ada 2005, the error message is modified to indicate that the
21804 type's stream attributes must be visible (again, only for -gnat05).

21836 types use the corresponding record type. This was not needed before
21837 the implementation of Ada 2005 synchronized types because
21838 concurrent types were never tagged types in Ada 95.

21966 * socket.c: Add extern int h_errno for rtems since networking header
21967 files are not available at this point in a tool bootstrap. Newlib

21989 can't handle that case.
21991 2005-11-17 Laurent Guerby <laurent@guerby.net>
21994 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22084 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22085 elementary types using the operator in standard. It is cleaner not to
22086 modify the programmers intent, especially in the case of floating-point.
22087 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22088 it did not matter because we always rewrote a/=b to not(a=b).
22089 (Expand_Allocator_Expression): For an allocator expression whose nominal
22090 subtype is an unconstrained packed type, convert the expression to its
22091 actual constrained subtype.
22092 Implement warning for <= or >= where < or > not possible
22093 Fix to Vax_Float tests (too early in many routines, causing premature
22094 Vax_Float expansions.

22108 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22109 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22111 Include -gnatwx as part of -gnatg (warn on redundant parens)
22112 Allow optional = after -gnatm
22113 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22114 longer sets Elaboration_Checks.
22115 Code to set warning mode moved to Sem_Warn
22116 so that it can be shared by pragma processing.
22118 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if

22130 * exp_vfpt.adb: Handle /= case
22131 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22243 we are not defining the type.
22244 <E_Record_Type>: Likewise.
22245 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22246 to get advantage of the new maybe_stabilize_reference interface, to
22247 ensure that what we reference is indeed stabilized instead of relying
22248 on assumptions on what the stabilizer does.
22249 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22250 type imported through a limited_with clause, use its non-limited view.
22251 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22253 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22254 of #if sections + explicit comparisons of convention identifiers.

22256 before early-returning for certain types when code generation is
22258 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22260 that we are not defining.
22261 (elaborate_expression_1): Do not create constants when creating
22262 variables needed by the debug info: the dwarf2 writer considers that
22263 CONST_DECLs is used only to represent enumeration constants, and emits
22265 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22266 object with an address clause into an indirect reference, drop the
22267 initializing expression.
22269 (STACK_CHECK_BUILTIN): Delete.
22270 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22279 subtype to build an actual type with bounds template.
22280 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22281 is provided by the front-end, use that subtype to compute the size of
22282 the deallocated object.

22284 check for a potential violation of a No_Elaboration_Code restriction.

22289 maybe_stabilize, for common uses without restriction on lvalues and
22290 without need to check for the success indication.
22291 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22292 pass false instead of 0 as the FORCE argument which is a bool.
22293 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22294 attached to a renaming pointer has been properly stabilized, as no such
22295 object is attached otherwise.
22296 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22297 function uses the "target pointer" return mechanism.
22298 Reinstate conversion of the actual to the type of the formal
22299 parameter before any other specific treatment based on the passing
22300 mechanism. This turns out to be necessary in order for PLACEHOLDER
22301 substitution to work properly when the latter type is unconstrained.

22305 (maybe_stabilize_reference): New function, like gnat_stabilize_reference
22306 with extra arguments to control whether to recurse through non-values
22307 and to let the caller know if the stabilization has succeeded.
22309 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22310 static output of record constructor if all the components are constant.
22311 (gnat_build_constructor): For a record type, sort the list of field
22312 initializers in increasing bit position order.
22313 Factor common code to build a storage type for an unconstrained object
22314 from a fat or thin pointer type and a constrained object type.
22315 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22316 types variants, and process special cases of VIEW_CONVERT expressions
22317 as their NOP_EXPR counterpart to ensure we get to the
22318 CORRESPONDING_VARs associated with CONST_DECls.
22319 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22320 on the right-hand side.
22322 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22325 are converting back to its original type.
22326 (convert) <JM input>: Fallthrough regular conversion code instead of
22327 extracting the object if converting to a type variant.
22328 (create_var_decl): When a variable has an initializer requiring code
22329 generation and we are at the top level, check for a potential violation
22330 of a No_Elaboration_Code restriction.
22331 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22332 SIZE and SIZE_UNIT which we need for later back-annotations.

22335 is an unchecked union.
22336 (pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
22337 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22338 main variant, just replace the VIEW_CONVERT_EXPR.

22474 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22475 for task component, in the case of a limited aggregate. The enclosed

22516 with an actual subtype so GIGI can make a correct size computation.
22517 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22518 'Unrestricted_Access, if the designated type is an interface we
22519 add a type conversion to force the displacement of the pointer
22520 to the secondary dispatch table.
22521 Use Universal_Real instead of Long_Long_Float when we need a high
22522 precision float type for the generated code (prevents gratuitous
22523 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22524 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22525 'Terminated for task interface class-wide objects. Generate a call to
22526 the predefined dispatching routine used to retrieve the _task_id from
22527 a task corresponding record.

22556 the return value into its actual subtype in order to help the backend
22557 to return the actual size instead of the maximum. This is another

22583 (Send_Signal): Release the process handle.
22585 2005-11-14 Robert Dewar <dewar@adacore.com>
22587 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we

22589 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)
22592 * exp_imgv.adb: Use Universal_Real instead of Long_Long_Float when we

22607 attribute of the N_Free_Statement.
22608 Generate itype for classwide designated object in both cases of
22609 user-specified storage pool: specific and class-wide, not only in the
22611 Raise CE when trying to set a not null access type object to null.
22612 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22613 an explicit loop, because freeze nodes make its position variable.

22888 In addition some minor reorganization of the code has been done to
22889 leave it more clear.
22890 (Analyze_Type_Declaration): If type has previous incomplete tagged
22891 partial view, inherit properly its primitive operations.

22919 subprogram declaration.
22920 Change name Is_Package to Is_Package_Or_Generic_Package
22921 (Process_Formals): A non null qualifier on a non null named access

22933 package associated with a generic instance or formal package, the
22934 private declarations of the parent must be installed (by calling new

22936 Change name Is_Package to Is_Package_Or_Generic_Package
22937 (Preserve_Full_Attributes): For a synchronized type, the corresponding

22943 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
22944 not try to rewrite a renamed stream attribute, because the operations
22945 on the type may not have been generated.
22946 Handle properly a renaming_as_body generated for a stream operation
22947 whose default is abstract because the object type itself is abstract.
22948 (Find_Type): If the type is incomplete and appears as the prefix of a
22949 'Class reference, it is tagged, and its list of primitive operations
22950 must be initialized properly.
22951 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22952 private declaration of a parent unit, prior to compiling the private
22953 part of a child unit, find on the scope stack the proper parent entity
22954 on which to link the use clause.

22977 (Valid_Conversion): If the operand has a single interpretation do not
22978 remove address operations.
22979 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22980 statement to inhibit warning.
22981 (Resolve_Unary_Op): Do not produce a warning when
22982 processing an expression of the form -(A mod B)
22983 Use Universal_Real instead of Long_Long_Float when we need a high

22986 (Resolve_Concatenation_Arg): Improve error message when argument is an
22987 ambiguous call to a function that returns an array.
22988 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that

23963 Hristian Kirtchev <kirtchev@adacore.com>
23964 Javier Miranda <miranda@adacore.com>
23966 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23967 from object notation, the original node is unanalyzed and carries no
23968 semantic information, so that accessiblity checks must be performed on
23969 the type of the actual itself.
23970 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23971 compatibility with Build_Protected_Sub_Specification.
23972 (Check_Overriding_Inherited_Interfaces): Add suport to handle

23978 include the generation of dispatching subprograms when the type
23979 implements at least one interface.
23981 * lib.ads: Extend information in Load_Stack to include whether a given
23982 load comes from a Limited_With_Clause.
23984 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
23985 whether a potential circularity is harmless, because it includes units
23986 loaded through a limited_with clause. Extends previous treatment which
23987 did not handle properly arbitrary combinations of limited and
23988 non-limited clauses.
23990 2005-09-01 Nicolas Setton <setton@adacore.com>
23992 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

24005 * exp_intr.adb (Expand_Source_Name): For Enclosing_Entity, generate
24006 fully qualified name, to distinguish instances with the same local name.
24008 * g-souinf.ads (Enclosing_Entity): Document that entity name is now

24020 (Close): Deallocate any existing filter for the concerned connection
24022 2005-09-01 Laurent Pautet <pautet@adacore.com>
24024 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24025 position set is provided, we compute one in order to reduce the maximum
24026 length of the keys. This computation first selects a character
24027 position between 1 and the minimum length of the keys in order to
24028 avoid reducing one of the keys to an empty string.
24029 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24030 does not converge. The initialization procedure now comes with a
24031 maximum number of iterations such that when exceeded, an exception is
24032 raised in Compute. The user can initialize this ratio to another value
24034 Reformating and updated headers.
24036 2005-09-01 Javier Miranda <miranda@adacore.com>
24038 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24039 that given an entity T creates and returns an Itype that duplicates the
24040 contents of T. The returned Itype has the null-exclusion
24041 attribute set to True, and its Etype attribute references T
24042 to keep the association between the two entities.
24043 Update copyright notice
24045 * sem_aggr.adb (Check_Can_Never_Be_Null,
24046 Aggregate_Constraint_Checks, Resolve_Aggregate,
24047 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
24049 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

24067 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24068 instead of Set_Subtype_Mark.

24076 N_Function_Specification.
24077 (Set_Result_Definition): New procedure for N_Function_Specifications.
24078 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24079 and N_Function_Specification.
24081 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24082 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
24083 Add support for LIMITED NEW for Ada 2005 AI-419
24084 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24085 syntax for anonymous access results.

24104 (Write_ALI): For D lines, on platforms where file names are
24105 case-insensitive, record the file names in lower case.
24107 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24108 Emmanuel Briot <briot@adacore.com>

24137 * snames.h, snames.ads, snames.adb: Introduce entries in
24138 Preset_Names for Name_Disp_Asynchronous_Select,
24139 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24140 Name_Disp_Timed_Select.
24141 New pragma Debug_Policy
24143 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24145 Switch -gnata also sets Debug_Pragmas_Enabled
24147 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24148 handle an explicit -gnata when compiling predefined files.
24150 2005-09-01 Vincent Celier <celier@adacore.com>
24152 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24153 directories of projects that have no Ada sources.
24155 2005-09-01 Robert Dewar <dewar@adacore.com>
24157 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24158 (makes a difference for wide characters)
24160 * widechar.adb, widechar.ads:
24161 Add Wide_Char_Byte_Count feature to count chars vs bytes
24163 2005-09-01 Thomas Quinot <quinot@adacore.com>
24164 Ed Schonberg <schonberg@adacore.com>
24165 Robert Dewar <dewar@adacore.com>
24167 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24168 'Address attribute reference with an overloaded prefix, use the
24169 location of the prefix (not the location of the attribute reference) as
24170 the error location.
24171 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24172 a function renaming thereof, is a valid prefix for 'Size (where it is
24173 intepreted as a function call).
24174 (Statically_Denotes_Entity): New predicate to determine whether the
24175 prefix of an array attribute can be considered static.
24178 (Eval_Attr): Fix failure to evaluate Component_Size for
24179 unconstrained arrays (resulted in wrong value in packed case, since
24180 back end cannot handle this case)
24182 2005-09-01 Robert Dewar <dewar@adacore.com>
24184 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24185 error msgs for most common cases.

24188 2005-09-01 Javier Miranda <miranda@adacore.com>
24189 Ed Schonberg <schonberg@adacore.com>
24191 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24192 become local to the whole package.
24193 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24194 the package was already analyzed the new algorithm "replaces" the
24195 real entities by the shadow ones. This is required to ensure that
24196 the order of these entities in the homonym chains does not change;
24197 otherwise we can have undefined references at linking time because
24198 in case of conflicts the external name of the entities will have
24199 a suffix that depends on the order of the entities in the chain.
24200 (Remove_Limited_With_Clause): Complementary code that completes the
24201 new algorithm and replaces the shadow entities by the real ones.
24202 (Install_Limited_Withed_Unit): When unchaining entities before the
24203 installation of the shadow entities, only regular entities of the
24204 public part must be taken into account. This is required to
24205 keep this routine in synch with the work done by Remove_Limited_
24207 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24208 even if unit is analyzed, because the analysis of the unit is
24209 idempotent in any case, and the limited view of the unit may have to
24210 be installed for proper visibility.
24211 (Expand_Limited_With_Clause): Even if the unit in the implicit
24212 with_clause has been analyzed already, a limited view of the package
24213 must be built for the current context, if it does not exist yet.
24215 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24216 Javier Miranda <miranda@adacore.com>
24217 Gary Dismukes <dismukes@adacore.com>
24219 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24220 defining entity for the instance body, make a new defining identifier
24221 rather than copying the entity of the spec, to prevent accidental
24222 sharing of the entity list.
24223 (Check_Private_View): When exchanging views of private types, build the
24224 list of exchanged views as a stack, to ensure that on exit the exchanges
24225 are undone in the proper order.
24226 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24227 Restore the compilation environment in case of instantiation_error.
24228 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24229 for an anonymous access result.
24230 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24231 (Formal_Entity): Handle properly the case of a formal package that
24232 denotes a generic package renaming.

24236 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24237 clause if the array aggregate is surrounded by parentheses.

24241 Ed Schonberg <schonberg@adacore.com>
24242 Javier Miranda <miranda@adacore.com>
24244 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24246 to check if a type is Constrained in cases related to code generation
24247 (rather than semantic checking) since otherwise we do not generate
24248 similar code for mutable private types depending if their
24249 discriminants are visible or not.
24250 (Check_Abstract_Overriding): Do not complain about failure to override
24251 the primitive operations used in dispatching selects since they will
24252 always be overriden at the freeze point of the type.
24253 (Access_Definition): Separate out handling for resetting the scope
24254 of an anonymous access function result type. Retrieve the scope
24255 of the associated function rather than using Current_Scope, which
24256 does not have a consistent value (depends on whether we're in the
24257 middle of analyzing formal parameters). Add ??? comment about
24258 finding a cleaner way to handle the special cases of scope setting.
24259 (Process_Incomplete_Dependents): A protected operation is never a
24260 dispatching operation (only its wrapper may be).
24261 (Build_Derived_Record_Type): In case of tagged private types that
24262 implement interfaces add derivation of predefined primitive
24264 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24265 by two parameters that are used in case of derivation from abstract
24266 interface types: No_Predefined_Prims is used to avoid the derivation
24267 of predefined primitives from the interface, and Predefined
24268 Prims_Only is used to complete the derivation predefined primitives
24269 in case of private tagged types implementing interfaces.
24270 Fix typo in comments
24271 (Find_Interface_In_Descendant): Protect the frontend against
24272 wrong code with large circularity chains.
24273 (Is_Private_Overriding): Add support for entities overriding interface
24274 subprograms. The test failed because Entities associated with overriden
24275 interface subprograms are always marked as hidden (and used to build
24276 the secondary dispatch table); in this case the overriden entity is
24277 available through the field abstract_interface_alias (cf. override_
24278 dispatching_operation)
24279 (Access_Definition): Set the scope of the type to Current_Scope for the
24280 case of a function with an anonymous access result type.
24281 (Access_Subprogram_Declaration): Handle creation of the type entity for
24282 an access-to-function type with an anonymous access result.
24283 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24284 in handling for N_Access_Function_Definition.
24285 (Analyze_Subtype_Declaration): Modify the text of error message.
24286 (Derived_Type_Declaration): Modify the text of error message.
24287 (Process_Subtype): Modify the text of error message plus cleanup
24288 of one redundant error message.
24289 (Analyze_Component_Declaration): Code cleanup.
24290 (Analyze_Object_Declaration): Code cleanup.
24291 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24292 attribute in case of access types. Code cleanup.
24293 (Array_Type_Declaration): Code cleanup.
24294 (Process_Discriminants): Create the new null-excluding itype
24295 if required. Code cleanup.
24296 (Process_Subtype): Create the new null-excluding itype if
24297 required. Code cleanup.
24298 (Build_Derived_Record_Type): Code cleanup to avoid calling
24299 twice the subprogram derive_subprograms in case of private
24300 types that implement interfaces. In this particular case the
24301 subprogram Complete_Subprograms_Derivation already does the
24302 job associated with the second call.
24304 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24305 conversion to the full view when generating an operation for a
24306 discriminant whose type may currently be private.
24308 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24309 Javier Miranda <miranda@adacore.com>
24311 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24312 V (Obj.F), the rewriting does not involve the indexed component, but
24313 only the selected component itself.
24314 Do not apply the transformation if the analyzed node is an actual of a
24315 call to another subprogram.
24316 (Complete_Object_Operation): Retain the entity of the
24317 dispatching operation in the selector of the rewritten node. The
24318 entity will be used in the expansion of dispatching selects.
24319 (Analyze_One_Call): Improve location of the error message associated
24321 (Analyze_Selected_Component): No need to resolve prefix when it is a
24322 function call, resolution is done when parent node is resolved, as
24324 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24325 when attempting to resolve a call transformed from its object notation.
24326 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24327 of the argument list for each interpretation of the operation.
24328 (Try_Object_Operation): The designated type of an access parameter may
24329 be an incomplete type obtained through a limited_with clause, in which
24330 case the primitive operations of the type are retrieved from its full
24332 (Analyze_Call): If this is an indirect call, and the return type of the
24333 access_to_subprogram is incomplete, use its full view if available.
24335 2005-09-01 Javier Miranda <miranda@adacore.com>
24336 Gary Dismukes <dismukes@adacore.com>
24338 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24339 access types the null-exclusion and access-to-constant attributes must
24341 (Analyze_Return_Statement): When the result type is an anonymous access
24342 type, apply a conversion of the return expression to the access type
24343 to ensure that appropriate accessibility checks are performed.
24344 (Analyze_Return_Type): For the case of an anonymous access result type,
24345 generate the Itype and set Is_Local_Anonymous_Access on the type.
24346 Add ??? placeholder for check to disallow returning a limited object
24347 in Ada 2005 unless it's an aggregate or a result of a function call.
24348 Change calls from Subtype_Mark to Result_Definition.
24349 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24350 Result_Definition in call to Make_Function_Specification.
24351 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24352 Set_Result_Definition.
24353 (Make_Inequality_Operator): Change formal Subtype_Mark to
24354 Result_Definition in call to Make_Function_Specification.
24355 (Process_Formals): Create the new null-excluding itype if required.
24356 (New_Overloaded_Entity): For an entity overriding an interface primitive
24357 check if the entity also covers other abstract subprograms in the same
24358 scope. This is required to handle the general case, that is, overriding
24359 other interface primitives and overriding abstract subprograms inherited
24360 from some abstract ancestor type.
24361 (New_Overloaded_Entity): For an overriding entity that comes from
24362 source, note the operation that it overrides.
24363 (Check_Conformance, Type_Conformant): Addition of one new formal
24364 to skip controlling formals in the analysis. This is used to
24365 handle overloading of abstract interfaces.
24366 (Base_Types_Match): Add missing case for types imported from
24367 limited-with clauses
24368 (New_Overloaded_Entity): Add barrier to protect the use of
24369 the "alias" attribute.
24371 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24373 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24374 verify that the procedure and the entry are mode conformant.
24375 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24376 as a different operator, which is often a cut-and-paste error.
24378 2005-09-01 Javier Miranda <miranda@adacore.com>
24379 Ed Schonberg <schonberg@adacore.com>
24381 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24382 used in controlling parameters exclude null because it is necessary to
24383 read the tag to dispatch, and null has no tag.
24384 (Override_Dispatching_Operation): If the previous operation is inherited
24385 from an interface, it becomes hidden and does not participate in later
24388 2005-09-01 Javier Miranda <miranda@adacore.com>
24389 Ed Schonberg <schonberg@adacore.com>
24390 Gary Dismukes <dismukes@adacore.com>
24392 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24393 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24394 the expander will generate the corresponding run-time check to evaluate
24396 (Resolve_Call): Check for legal type of procedure name or prefix that
24397 appears as a trigger in a triggering alternative.
24398 (Valid_Conversion): If expression is ambiguous and the context involves
24399 an extension of System, remove System.Address interpretations.
24400 (Resolve_Qualified_Expression): Reject the case of a specific-type
24401 qualification applied to a class-wide argument. Enhance comment
24402 to explain checking of Original_Node.
24403 (Resolve_Type_Conversion): The location of the error message was not
24404 general enough to handle the general case and hence it has been removed.
24405 In addition, this patch improves the text of the message.
24406 (Resolve_Type_Conversion): Add missing support for access to interface
24408 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24409 do not expand if the expression is the actual in a call, because proper
24410 expansion will take place when the call itself is expanded.
24411 (Resolve_Allocator): If the context is an unchecked conversion, the
24412 allocator inherits its storage pool, if any, from the target type of
24415 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24416 Javier Miranda <miranda@adacore.com>
24418 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24419 inherited interface operation that has an implementation, use the
24420 implementation to avoid spurious ambiguities.
24421 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24422 use the Corresponding_Record_Typ attribute to look for the interface
24423 because it is set by the expander (and hence it is not always
24424 available). For this reason we traverse the list of interfaces
24425 (available in the parent of the concurrent type).
24426 (Interface_Present_In_Ancestor): Handle entities from the limited view
24428 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24430 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24431 from the list of required components.
24432 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24433 primitive procedure of a limited interface with a controlling first
24435 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24437 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24438 capture if it is generated in the second operand of a short-circuit
24440 Do not capture values for variables with address clauses.
24441 (Is_Object_Reference): Treat a function call as an object reference only
24442 if its type is not Standard_Void_Type.
24444 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24446 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24447 to a variable that is statically known to be constant.

24464 Document new treatment of wide characters in max line length
24466 Remove -gnatL/-gnatZ switches, no longer used.
24467 Add note on pragmas Assertion_Policy and Debug_Policy in discussion

24471 Float_Representation.
24472 Add documentation for pragma No_Strict_Aliasing

25229 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25230 longer protected objects. They have been replaced by lower-level
25231 suspension objects made up by a mutex and a condition variable (or
25232 their equivalent given a particular OS) plus some internal data to
25233 reflect the state of the suspension object.
25234 (Initialize, Finalize): Add this initialization procedure for
25235 Suspension_Object, which is a controlled type.
25236 (Finalize): Add the finalization procedure for Suspension_Object,
25237 which is a controlled type.
25239 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of

25241 VxWorks specific version of this package. Target dependencies
25242 has been moved to System.Task_Primitives.Operations.
25244 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25246 (InitializeCriticalSection, EnterCriticalSection,
25247 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25248 pCriticalSection by an anonymous access type so that we avoid problems
25249 of accessibility to local objects.

25256 set the environment task mask here.
25257 (Current_State): Add this function that returns the state of the
25259 (Set_False): Add this procedure that sets the state of the suspension
25261 (Set_True): Add this procedure that sets the state of the suspension
25262 object to True, releasing the task that was suspended, if any.
25263 (Suspend_Until_True): Add this procedure that blocks the calling task
25264 until the state of the object is True. Program_Error is raised if
25265 another task is already waiting on that suspension object.
25266 (Initialize): Add this procedure for initializing the suspension
25267 object. It initializes the mutex and the condition variable which are
25268 used for synchronization and queuing, and it sets the internal state
25270 (Finalize): Add this procedure for finalizing the suspension object,
25271 destroying the mutex and the condition variable.

25276 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25277 which provides a low-level abstraction (using operating system
25278 primitives) for Ada.Synchronous_Task_Control.
25279 This object is made up by a mutex (for ensuring mutual exclusion), a
25280 condition variable (for queuing threads until the condition is
25281 signaled), a Boolean (State) indicating whether the object is open,
25282 and a Boolean (Waiting) reflecting whether there is a task already
25283 suspended on this object.

25725 way as a normal component of an anonymous access type.
25726 (Resolve_Allocator): When an allocator's designated type is a class-wide
25727 type, check that the accessibility level of type given in the

25748 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25749 check on possible violation of restriction No_Direct_Boolean_Operators

26756 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26759 error messages if expansion has been disabled due to previous
26760 (unrelated) errors).
26762 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26763 is disabled, the entity denoted by the argument is the access type
26764 itself, not an underlying record type, so there is no need to go back
26765 to the Corresponding_Remote_Type.

26775 denotes a type in the class.
26776 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26777 of Name_Generic_Dispatching_Constructor.
26779 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada
26780 05 unit for AI-260-02).

26794 the case of renaming of stream attributes when the renaming denotes a
26795 generic formal subprogram association for an abstract formal subprogram.
26796 Check that the attribute is a primitive stream attribute (and not
26797 a class-wide stream attribute) and then rewrite the attribute name
26798 as the name of the appropriate compiler-generated stream primitive.

26802 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26810 itype whose parent is controlled and not yet frozen, do not create a
26811 freeze node for the itype if expansion is disabled.
26813 2005-03-29 Vincent Celier <celier@adacore.com>
26815 * make.adb (Gnatmake): Don't fail if the main project file is declared
26816 as having no Ada sources. Do not display message "no sources to
26817 compile" in quiet output.

26821 * Makefile.in [VMS] (EXTRA_GNATTOOLS): Add vms_help and gnat.hlp as

26837 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
26838 rather than proceed ahead using a junk attribute name.
26840 2005-03-29 Vincent Celier <celier@adacore.com>
26842 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
26844 * prj-part.adb (Parse_Single_Project): Set the location of a project
26845 on its defining identifier, rather than on the reserved word "project".
26847 * prj-proc.adb (Expression): Adapt to the fact that default of external
26848 references may be string expressions, not always literal strings.
26849 (Recursive_Process): Set Display_Name equal to Name
26850 when Location is No_Location, that is when there is no actual file.
26851 Get the Display_Name of the project from the source, when it is not a
26853 (Process): Use the Display_Name in error messages
26855 * prj-strt.adb (External_Reference): Allow default to be string

27518 Update documentation on Must_Be_Byte_Aligned for new spec
27520 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27521 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27522 uses of the Access_Disp_Table attribute to reference the first dispatch
27523 table associated with a tagged type. As
27524 part of the implementation of abstract interface types,
27525 Access_Disp_Table has been redefined to contain a list of dispatch
27526 tables (rather than a single dispatch table).
27527 Similarly, upgrade all the references to Tag_Component by the
27528 new attribute First_Tag_Component.
27529 (Find_Inherited_TSS): Moved to exp_tss.
27530 Clean up test in Expand_N_Object_Declaration for cases
27531 where we need to do a separate assignment of the initial value.

27533 declaration of a tagged type is an aggregate, no need to generate an
27534 additional tag assignment.
27535 (Freeze_Type): Now a function that returns True if the N_Freeze_Entity
27537 Bit packed array ops are only called if operands are known to be
27539 (Component_Equality): When returning an N_Raise_Program_Error statement,
27540 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27541 expects that only expressions have a bona fide type).
27542 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27543 determine the amount of data to be copied.
27545 * par.adb (P_Interface_Type_Definition): New subprogram that parses the
27546 new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):

27573 (Task_Body_Procedure): Removed.
27574 (Set_Task_Body_Procedure): Removed.
27575 These subprogram have been removed because the attribute
27576 Task_Body_Procedure has been moved to the corresponding task type
27577 or task subtype entity to leave a field free to store the list
27578 of interfaces implemented by a task (for AI-345)
27579 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27580 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27581 expression flag Do_Range_Check
27582 (Exception_Junk): Change to Flag7 to accomodate above change
27583 (Box_Present, Default_Name, Specification, Set_Box_Present,
27584 Set_Default_Name, Set_Specification): Expand the expression
27585 "X in N_Formal_Subprogram_Declaration" into the corresponding
27586 two comparisons. Required to use the csinfo tool.

27589 "with string" given.
27591 * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
27594 * par-ch11.adb (P_Raise_Statement): Recognize with string expression
27597 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27598 attribute Task_Body_Procedure rather than the old semantic field that
27599 was available in the task_type_declaration node.
27601 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27602 interface type definitions.
27603 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27606 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
27607 task type declaration.

27609 protected type declaration.
27611 2005-03-15 Doug Rupp <rupp@adacore.com>
27612 Vincent Celier <celier@adacore.com>
27614 * bindgen.adb (Gen_Main_C): Change WBI __posix_exit to decc$posix_exit
27615 (Gen_Output_File_C): Likewise.

27620 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27621 is an N_Raise_Constraint_Error node, create a new copy of it without
27622 going through a call to Duplicate_Subexpr.

27627 Ed Schonberg <schonberg@adacore.com>
27633 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27634 representation clause that prescribes a size not equal to the rounded
27635 size of their types.
27636 (gnat_to_gnu_entity, case E_Component): Always look at
27637 Original_Record_Component if Present and not the entity.
27638 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27639 of tagged extension types by not making field for components that are
27641 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27642 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27643 expression to the type of the object when the object is constant.
27644 Reverse defer_debug_incomplete_list before traversing it, so that trees
27645 are processed in the order at which they were added to the list. This
27646 order is important when using the stabs debug format.
27647 If we are deferring the output of debug information, also defer this
27648 output for a function return type.
27649 When adding fields to a record, prevent emitting debug information
27650 for incomplete records, emit the information only when the record is
27652 (components_to_record): New parameter defer_debug.
27653 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27654 (gnat_to_gnu_field_decl): New function.

27656 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27657 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27658 No longer update discriminants to not be a COMPONENT_REF.
27659 (copy_alias_set): Strip padding from input type; also handle
27660 unconstrained arrays properly.
27662 * gigi.h (write_record_type_debug_info): New function.
27663 Convert to use ANSI-style prototypes. Remove unused
27664 declarations for emit_stack_check, elab_all_gnat and

27673 (convert) <UNION_TYPE>: Accept slight type variations when
27674 converting to an unchecked union type.
27676 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27677 replace the N_Freeze_Entity with a null statement.
27679 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27680 within a constrained subcomponent of an enclosing record, place the

27683 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27684 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27685 within records; allow them to have freeze nodes if their base types
27688 * exp_util.adb (Remove_Side_Effects): Properly test for
27689 Expansion_Delayed and handle case when it's inside an
27690 N_Qualified_Expression.
27692 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27693 Comes_From_Generic, to recognize accurately that the parent type in a
27694 derived type declaration can be traced back to a formal type, because
27695 it is one or is derived from one, or because its completion is derived
27697 (Constrain_Component_Type): If component comes from source and has no
27698 explicit constraint, no need to constrain in in a subtype of the
27700 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27701 Minor change to propagate Is_Ada_2005 flag
27703 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27704 Expansion_Delayed is False.
27705 (assoc_to_constructor): Ignore fields that have a
27706 Corresponding_Discriminant.
27707 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27708 function returns "by target", dereference the target pointer using the
27709 type of the actual return value.
27710 <all>: Be prepared for a null gnu_result.
27711 (processed_inline_subprograms): Check flag_really_no_inline
27712 instead of flag_no_inline.

27723 Must_Be_Byte_Aligned for cases where we do not need to use a
27724 System.Pack_nn unit.
27726 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27728 Needed now that we do some processing for IN parameters as well. This
27729 may well fix some unrelated errors.
27730 (Expand_Call): Handle case of unaligned objects (in particular those
27731 that come from packed arrays).
27732 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27733 renamed entity is an inherited operation, re-expand the call using the
27734 original operation, which is the one to call.
27735 Detect attempt to inline parameterless recursive subprogram.
27736 (Represented_As_Scalar): Fix to work properly with private types
27737 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27738 accurate estimate. Yields True in far fewer cases than before,
27739 improving the quality of code that depends on this test.
27741 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27742 over both visible and private declarations to remove them from tree,
27743 and mark subprograms declared in package as eliminated, to prevent
27744 spurious use in subsequent compilation of generic units in the context.
27746 * exp_util.ads: Minor cleanup in variable names
27748 * sem_eval.ads, sem_eval.adb: Minor reformatting
27749 (Compile_Time_Known_Bounds): New function

27753 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27754 determining whether an unchecked conversion is needed for the argument
27755 of an initialization call.
27757 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27759 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27760 that appears in the instantiation rather than the internal subtype
27761 generated in the wrapper package, to avoid anomalies in gigi when the
27762 target is derived from a private type whose full view is an access type.
27764 2005-03-15 Robert Dewar <dewar@adacore.com>
27766 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27768 Add documentation to replace the use of this flag
27769 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27772 2005-03-15 Thomas Quinot <quinot@adacore.com>
27774 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27775 here from exp_attr so it can be shared between exp_attr and exp_dist.
27776 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27777 all TSS names, not a subset thereof, and the previous name introduced
27778 an unnecessarily confusion that a distinction might exist between
27779 "OK" TSS names and some "not OK" TSS names.
27781 2005-03-15 Doug Rupp <rupp@adacore.com>
27783 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27786 2005-03-15 Pascal Obry <obry@adacore.com>
27787 Eric Botcazou <ebotcazou@adacore.com>
27791 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27792 when IN_RTS. This is to work around a bootstrap path problem.
27794 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27795 table and pass it to __gnat_install_SEH_handler().
27796 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27798 * lang.opt: Fix specification of -fRTS=.

27802 Vincent Celier <celier@adacore.com>
27803 Arnaud Charlet <charlet@adacore.com>
27806 This change works fine when gnatlib is built from the gcc directory,
27807 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27808 is not passed to ada/Makefile.in, so more work is needed by a
27809 Makefile/configure expert.
27811 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27812 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27813 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27815 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.

27820 2005-03-15 Robert Dewar <dewar@adacore.com>
27822 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27824 * impunit.adb: Add GNAT.UTF_32
27826 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27828 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27829 now uses GNAT.UTF_32).
27831 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27832 capabilities for categorizing characters using Unicode categories
27834 2005-03-15 Ed Schonberg <schonberg@adacore.com>

27843 Ed Schonberg <schonberg@adacore.com>
27845 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27846 parameter reported some error we immediately return. This improves the
27847 behaviour of the frontend in case of errors.
27848 (Install_Parent, Remove_Parent): Introduce new flag
27849 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27850 ancestor of a generic child unit, when the child is being instantiated.
27851 (Inline_Instance_Body): If we are compiling the private
27852 part or the body of a child unit, restore the proper visibility of the
27853 parents after compiling the instance body.

27856 Javier Miranda <miranda@adacore.com>
27859 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27860 of a private type, in which case it is underlying_type that denotes
27861 the proper task. Also modified to use the new entity attribute
27862 that is directly available in the task type and task subtype entities
27863 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27864 arrays when other dimensions than the first are constrained by
27865 discriminants of an enclosing record.
27866 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27867 a combination of indexed and selected components, find ultimate entity
27868 and generate the appropriate reference for it, to suppress spurious
27870 (Note_Possible_Modification): If an entity name has no entity, return.
27871 (Is_Variable): A function call never denotes a variable.
27872 (Requires_Transient_Scope): For record types, recurse only on

27878 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27879 Eliminated as candidates for resolution. Both efficient, and avoids
27880 anomalies with operators declared in deleted code.
27881 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27882 expansion is disabled (as when compiling a generic) to prevent spurious
27883 warnings on prefixes of selected components.
27885 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27887 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27888 attached to a list before checking whether it appears in the private
27889 declarations of the current package.
27890 (Make_Inequality_Operator): Insert declaration in proper declarative
27891 list rather than just setting the Parent field, so that
27892 Is_Private_Declaration can handle it properly.
27894 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27896 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27897 a renaming a body, check that the renamed subprogram in not intrinsic.
27898 (Find_Direct_Name): If several use_visible entities hide
27899 each other, and the context is a predefined file compiled through
27900 rtsfind, keep only the entity that comes from a predefined file.
27902 2005-03-15 Geert Bosch <bosch@adacore.com>
27904 * s-fatgen.adb (Valid): Extend special exceptions to account for long

28299 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28300 Remove ["0A"] from comment, since it can look like a line terminator.
28301 Currently we don't permit this, but this is under discussion by the
28302 ARG, and it is easy enough to use a different example.
28304 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28305 handling UTF-32 encoding for wide wide character.
28306 Implement new brackets coding ["hhhhhhhh"]

28313 (RT_Exception_Code): Addition of CE_Null_Not_Allowed; used to
28314 notify that constraint error will be raised at run-time
28315 because a null value is assigned to a null-excluding object.
28316 Remove some obsolete declarations and make Char_Code
28319 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28320 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28321 Rcheck subprograms.
28323 * checks.adb (Check_Null_Not_Allowed): Replace the error message on
28324 wrong null-exclusion value by a warning message.
28325 (Enable_Range_Check): Do range check if the prefix is an
28326 explicit dereference whose designated object is an unconstrained array.
28327 Current algorithm for removing duplicate checks is over-eager in this

28339 * exp_util.adb (Insert_Actions): Replace
28340 N_Formal_Subprogram_Declaration by
28341 N_Formal_{Abstract|Concrete}_Subprogram_Declaration.
28342 Char_Literal_Value field is now a Uint.
28344 * sinfo.ads, sinfo.adb (Corresponding_Formal_Spec): New function
28345 defined for subprogram renaming declarations. When set, the field
28346 indicates the defining entity of a corresponding formal subprogram
28347 when the renaming corresponds to a formal subprogram association in an
28349 (Set_Corresponding_Formal_Spec): New procedure to return
28350 Corresponding_Formal_Spec field.
28351 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28352 (which is now a subtype).
28353 Char_Literal_Value field is now a Uint
28355 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28356 pointer to the base of the dispatch table.
28357 Minor changes to comments.
28358 (Controlling_Type): New function for determining the tagged type
28359 associated with a tagged primitive subprogram.
28360 (Expand_Dispatching_Call): Add support for a controlling actual that is

28363 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28364 describing the new layout.
28365 (Dispatch_Table): The expander computes the actual array size, allocates
28366 the Dispatch_Table record accordingly, and generates code that displaces
28367 the base of the record after the Typeinfo_Ptr component. The access to
28368 these components is done by means of local functions.
28369 (Offset_To_Top): New function.
28370 (Typeinfo_Ptr): New function.
28371 (Get_TSD): Modified to access the new position of the TSD.
28372 (Set_TSD): Modified to save the TSD in its new position.
28374 * par-ch12.adb (P_Formal_Subprogram_Declaration): Add parsing for the
28375 case of formal abstract subprograms. Add check and message for -gnat05.
28378 * sem_ch12.adb: Add with and use for Sem_Disp.

28382 N_Formal_Subtype_Declaration (which is now a subtype).
28383 (Analyze_Formal_Subprogram): Add handling for
28384 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28385 dispatching, setting the controlling status of the formal parameters
28386 and result, and issuing an error if there is no controlling type for
28387 the formal subprogram.
28388 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28389 which is an unclean use of that field, we set the new field
28390 Corresponding_Formal_Spec to make the formal subprogram available to
28391 processing in Analyze_Subprogram_Declaration.
28392 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28393 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28394 Constrained, so that it is is does not statically match its anonymous
28397 * sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
28398 abstract formal subprograms in error check for functions returning
28399 abstract types. Set scope of new designator for
28400 a parameterless subprogram, so that it is available when checking the
28401 body for nested subprograms, before full analysis of said body.
28402 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28403 subprogram only if inner one comes from source.
28404 (Analyze_Function_Call): If the call is given in object notation, the
28405 analysis of the name rewrites the node and analyzes it with the proper
28406 argument list. After analyzing the name, if the call has been rewritten
28407 and the result type is set, no further analysis is needed.
28408 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28409 mark in function specification, in a context where the formals are
28410 visible and hide outer homographs.
28412 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28413 as the tagged type for the cases of abstract formal subprograms and
28414 renamings of those. Clean up spec comments.
28415 (Check_Dispatching_Context): Add error message to indicate "abstract
28416 procedure", covering the case of a call to a formal abstract procedure
28417 that has statically tagged operands.
28418 (Check_Dispatching_Call): Check for the case of an actual given by
28419 a tag-indeterminate function call whose type is an ancestor of the
28420 containing call's associated tagged type. This situation can occur
28421 for inherited primitives with function defaults. In this case we
28422 use the tagged type's tag directly as the controlling argument for
28424 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28426 * sprint.adb (Sprint_Node_Actual): Split
28427 N_Formal_Subprogram_Declaration into two alternatives for the new
28428 cases N_Formal_Abstract_Subprogram_Declaration and

28499 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
28503 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28504 on the field if Pragma Component_Alignment (Storage_Unit).
28505 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28506 side-effects as if it were a constant; also make SAVE_EXPR to protect
28508 (gnat_to_gnu_entity, case E_Record_Subtype): If have _Parent, make a
28510 (make_dummy_type): Set TYPE_UNCHECKED_UNION_P.
28511 (components_to_record): Test it.

28524 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28526 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28527 component of an array of arrays in an assignment context, and the
28528 aggregate has component associations that require sliding on
28529 assignment, force reanalysis of the aggregate to generate a temporary
28530 before the assignment.
28531 (Must_Slide): Make global to the package, for use in Gen_Assign.
28533 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28535 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28536 unchecked union with no inferable discriminants, return a
28537 Raise_Program_Error node, rather than inserting it at the point the
28539 (Expand_Record_Equality, Component_Equality): Handle properly the case
28540 where some subcomponent is an unchecked union whose generated equality
28541 code raises program error.
28543 2005-02-09 Doug Rupp <rupp@adacore.com>

28549 Arnaud Charlet <charlet@adacore.com>
28551 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28552 address of the exception registration. The Win32 version of this
28553 routine calls __gnat_install_SEH_handler() to initialize the SEH
28554 (Structured Exception Handling) handler.
28555 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28556 SEH (Structured Exception Handling) now.
28557 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28558 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28559 preprocessor condition protecting the call to the extra eh setup
28560 subprogram, which is only available for the ppc target.
28561 (__gnat_clear_exception_count): replaced reference to
28562 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28564 * seh_init.c: New file.
28566 * Make-lang.in: (GNAT_ADA_OBJS): Add seh_init.o.
28567 (GNATBIND_OBJS): Idem.
28569 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28570 routine takes a new parameter (a pointer to the exception registration
28571 for the SEH (Structured Exception Handling) support.
28573 * raise.h: (__gnat_install_SEH_handler): New prototype.
28574 Update copyright notice.
28576 * s-tassta.adb (Task_Wrapper): Declare the exception registration
28577 record and initialize it by calling __gnat_install_SEH_handler.

28587 Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
28588 [VMS]: Add translations for g-enblsp.adb.
28590 * s-asthan-vms.adb: Removed.
28591 * s-asthan-vms-alpha.adb: Added.

28602 -shared-libgcc is now used by default on some systems (e.g. linux with
28604 Remove references to Makefile.prolog/generic, no longer used.
28606 2005-02-09 Vincent Celier <celier@adacore.com>
28608 * prj-makr.adb (Process_Directory): Put file name in canonical case
28609 before matching against the patterns.
28610 If gnatname has been invoked as <prefix>-gnatname
28611 then invoke the compiler as <prefix>-gcc, not just "gcc".
28613 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28615 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28616 with expansion disabled. The actual subtype is needed among other
28617 places when the selected component appears in the context of a loop
28618 bound, and denotes a packed array.
28619 (Operator_Check): Always use the first subtype in the
28620 error message, to avoid the appearance of internal base types.
28621 (Transform_Object_Operation): Copy each actual in full
28622 to the parameter associations of the constructed call, rather than
28623 using the shallow copy mechanism of New_Copy_List. This ensures that
28624 the chaining of named associations is done properly.
28625 (Complete_Object_Operation): Rewrite node, rather than
28626 replacing it, so that we can trace back to the original selected
28629 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28630 and calls that use object notation, if the called function is not
28631 declared in a withed unit, place the elaboration constraint on the
28632 unit in the context that makes the function accessible.
28633 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28634 imposes an elaboration constraint between two packages.
28636 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28638 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28639 views of a private type after handling its private dependents, to
28640 maintain proper stack discipline between entry and exit from the
28643 2005-02-09 Cyrille Comar <comar@adacore.com>

28656 recursion warnings when compiled with -gnatdm.
28658 2005-02-09 Robert Dewar <dewar@adacore.com>
28660 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28661 Slight fix to documentation of -gnaty with no parameters
28663 * xr_tabls.ads: Add ??? comment for missing overall comment
28665 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28666 we now use by default.
28668 * xsnames.adb: Adjust end of file test to look for five space followed
28669 by '#' instead of six spaces. The format of xsnames.adb was modified
28670 in the last update.
28672 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28675 * clean.adb: Minor reformatting.
28677 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28678 gnatname.adb: Minor reformatting
28679 Add 2005 to copyright output when utility is run
28681 * csets.adb: Eliminate obsolete comment
28683 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28686 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28688 2005-02-09 Sergey Rybin <rybin@adacore.com>
28690 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28691 the difference between compact and incompact layout and add the record
28692 representation clause to the example illustrating different layouts.
28693 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28694 component clauses").
28696 2005-02-09 Florian Villoing <villoing@adacore.com>
28698 * gnat_ugn.texi: Fix typos.
28699 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28701 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28702 in the generated documentation.
28704 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28706 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28736 * s-osinte-vxworks.ads (taskPriorityGet): Add this function (imported
28737 from the VxWorks kernel) that is needed for getting the active
28738 priority of the different tasks.
28740 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28741 Use a pragma Elaborate_Body in the spec file instead.
28742 Noticed by code reading.
28744 2005-02-09 Thomas Quinot <quinot@adacore.com>
28746 * exp_util.ads: Minor correction in comment.
28748 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28750 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28751 since this procedure is now too complex to be worth inlining.

29406 "no bitfield creation", to be used by make_aligning_type. Don't
29407 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29408 fields claimed addressable still have to be bitfields. Use
29409 value_factor_p instead of a raw binop construction to check for the
29410 position's alignment.

29417 Ed Schonberg <schonberg@adacore.com>
29419 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29420 with an implicit dereference as its prefix, use
29421 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29423 prefix is generated, if appropriate.
29425 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29426 dereference is rewritten to an explicit one, generate a reference to
29427 the entity denoted by its prefix using the original prefix node, so

29429 access value, if appropriate.
29431 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29432 emitting 'assigned but never read' warning on a variable on the basis

29446 an external name, to be handled by the back end.
29448 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29449 subprogram which is Imported with convention Intrinsic if an
29450 External_Name argument is specified.
29451 (Process_Import_Or_Interface): Properly diagnose link name argument.
29452 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29477 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29478 PCS-specific part of Add_Stub_Type.

29505 (Generate_Reference): Handle properly a reference to an entry formal,
29506 when an accept statement has a pragma Unreferenced for it.
29508 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29509 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29510 the body, to ensure that warnings are properly emitted for each accept
29511 statement of a given task entry.

29533 (Remove_Next_Debug): Same fix
29535 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do

29539 (Remove_Next): Same cleanup
29541 2004-12-07 Thomas Quinot <quinot@adacore.com>
29543 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29544 used to record an implicit dereference as a read operation on its
29545 prefix when operating under -gnatc. Necessary to avoid spurious
29546 'variable assigned but never read' warnings in that mode.
29547 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29548 is a non-overloaded implicit dereference, call the above subprogram to
29549 ensure proper recording of references.
29551 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29553 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29554 to be resolved later as part of Analyze_Iteration_Scheme's call to

29601 2004-12-07 Vincent Celier <celier@adacore.com>
29603 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29604 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29605 and -eit to -ept. Added qualifier
29606 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29608 2004-11-27 Andreas Schwab <schwab@suse.de>
29610 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29612 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29614 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29615 internal implementation unit GNAT.Sockets.Thin,
29616 as their usage for sockets is non-portable (using the read and write
29617 functions from the system runtime library is fine on UNIX but won't
29618 work under Windows).
29620 * mingw32.h: Update copyright notice.
29622 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29674 new Others_Value and All_Others_Value objects.
29675 (struct attrib): Rename "arg" component as "args", since GCC expects a
29676 list of arguments in there.
29678 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29679 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29682 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29683 others_decl and all_others_decl instead of hardcoded dummy addresses
29684 to represent "others" and "all others" choices, which is cleaner and
29685 more flexible with respect to the possible eh pointer encoding policies.
29687 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29688 (process_attributes): Account for the naming change of the "args"
29689 attribute list entry component.
29691 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29692 cumulating attributes for different entities into a single list.
29693 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29694 attributes for the current entity and propagate first subtype
29695 attributes to other subtypes.
29696 <E_Procedure>: Attribute arguments are attr->args and not
29697 attr->arg any more.
29698 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29699 argument provided, as this is what GCC expects. Use NULL_TREE instead
29702 2004-11-18 Robert Dewar <dewar@adacore.com>
29704 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29737 (First_RCI_Subprogram_Id): Document this constant.
29738 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29740 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29741 replaced with calls to Get_Library_Unit_Name_String. Previously there
29742 were several instances of the same code in different locations in the
29743 compiler; this checkin completes the replacement of all of these
29744 instances with calls to a common subprogram.
29745 Minor reformatting.

29778 that the pragmas are properly attached to the tree, and that no
29779 nodes are improperly shared.
29781 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29782 pragmas to Exp_Prag, which is more appropriate.
29783 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29784 check for duplicates Remove use of Is_Psected flag, no longer needed.
29785 Use new Make_String_Literal function with string.
29787 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29788 that are functions return universal values, that have to be converted
29789 to the context type.
29790 Use new Make_String_Literal function with string.
29791 (Get_Stream_Convert_Pragma): New function, replaces the use of
29792 Get_Rep_Pragma, which had to be kludged to work in this case.
29794 * freeze.adb: Use new Has_Rep_Pragma function
29796 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29797 function with string.
29798 Use new Has_Rep_Pragma function.
29800 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29803 2004-11-18 Robert Dewar <dewar@adacore.com>
29805 * errout.ads, errout.adb: (First_Sloc): New function
29807 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29808 check (-gnatyx) instead of being included as a redundant construct
29811 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29812 Style_Check_Order_Subprograms.
29814 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29815 stylesw.adb: Add Style_Check_Xtra_Parens
29817 * usage.adb: Add line for -gnatyx (check extra parens)
29819 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29821 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29822 Robert Dewar <dewar@adacore.com>
29824 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29825 discriminant of a constrained subtype, analyze the copy of the
29826 corresponding constraint, because in some cases it may be only
29827 partially analyzed.
29828 Removes long-lived ??? comments.
29830 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29831 handled controlled or secondary-stack expressions within the
29832 iteration_scheme of a loop.
29834 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29835 bounds that may contain functions calls, to prevent memory leaks when
29836 the bound contains a call to a function that uses the secondary stack.
29837 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29838 generate temporaries for loop bounds that might contain function calls
29839 that require secondary stack and/or finalization actions.
29841 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29842 selected component and the selector is overloadable (not just a
29843 function) treat as function call, Analyze_Call will disambiguate if
29845 (Analyze_Selected_Component): Do not generate an actual subtype for the
29846 selected component if expansion is disabled. The actual subtype is only
29847 needed for constraint checks.
29848 (Analyze_Allocator): If restriction No_Streams is set, then do
29849 not permit objects to be declared of a stream type, or of a
29850 composite type containing a stream.
29852 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29853 No_Streams no longer prohibits with'ing this package.
29855 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29856 discriminants, but the parent base has unknown discriminants, there is
29857 no discriminant constraint to inherit. Such a discrepancy can arise
29858 when the actual for a formal type with unknown discriminants is a
29859 similar private type whose full view has discriminants.
29860 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29861 do not permit objects to be declared of a stream type, or of a
29862 composite type containing a stream.
29864 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29866 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29867 protected operations.
29869 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29870 generated name, it complicates decoding in gdb and hinders debugging
29871 of protected operations.
29872 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29873 flag for the protected entry barrier function.
29874 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29875 flag for the protected entry function.
29877 2004-11-18 Nicolas Setton <setton@adacore.com>
29879 * expect.c: Define __unix__ when __APPLE__ is defined.
29881 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29882 Darwin-specific section.
29884 * lang-specs.h: Change the placement of the %1 marker.
29885 Works around the fact that gcc adds -fPIC by default under Darwin.
29887 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29889 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29890 type of the object with the packed array type, set the Analyzed flag
29891 on the object if it is an entity or simple indexed component, to avoid
29892 spurious type errors.
29894 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29896 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29897 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29898 separate line from the version message.
29900 2004-11-18 Ed Falis <falis@adacore.com>
29902 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29904 (init_float): Eliminate initialization of floating point status for
29905 AE653. The instructions have no effect for vThreads.
29907 2004-11-18 Vincent Celier <celier@adacore.com>
29909 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29910 gnatbind is invoked with -shared.
29912 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29914 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29915 for Detect_Blocking which is redundant with the check done within the
29916 procedure Protected_Single_Entry_Call.
29917 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29918 Detect_Blocking which is redundant with the check done within the
29919 procedure Protected_Single_Entry_Call.
29921 2004-11-18 Vincent Celier <celier@adacore.com>
29923 * makegpr.adb (Compile): Put the compiling switches (in package
29924 Compiler and on the command line) immediately after "-c", instead of
29925 at the end of the command line invocation of the compiler, when
29926 compiling a non-Ada file.
29927 (Build_Global_Archive): When there is no need to rebuild the archive,
29928 set Global_Archive_Exists, so that the archive is passed to the linker
29931 2004-11-18 Robert Dewar <dewar@adacore.com>
29932 Sergey Rybin <rybin@adacore.com>
29935 Remove extra paren check from list of checks for redundant constructs
29936 Add documentation of new -gnatyx style check (check extra parens)
29937 Remove paragraph about gnatelim debug options.
29939 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29940 objects rather than forbidding dependencies on the package Ada.Streams.
29942 * sinfo.ads: Add ??? note that we should document pragmas passed to
29945 * g-expect.ads: Fix a few typos in the comments.
29947 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29949 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29952 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29954 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29956 2004-11-07 Andreas Schwab <schwab@suse.de>
29958 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29960 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29963 * Makefile.in (darwin): Set soext to .dylib.
29965 2004-10-26 Vincent Celier <celier@gnat.com>
29966 Thomas Quinot <quinot@act-europe.fr>
29968 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29969 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29970 there is no use of GNAT.Sockets.Constants.
29971 Remove remaining pragma Import for C_Write
29972 Remove C_Read and C_Write from internal implementation unit
29973 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29974 the read and write functions from the system runtime library is fine
29975 on UNIX but won't work under Windows).
29977 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29978 (Check_Selector): Use C_Recv instead of C_Read.
29979 Selectors are the GNAT.Sockets abstraction to perform a select()
29980 call on a set of descriptors. To allow abortion of an ongoing
29981 select operation, some data is written to a dedicated socket that
29982 is always monitored.
29983 Under Windows, the write and read library functions cannot operate
29984 on sockets, so we need to use send and recv instead, which is portable
29985 across all supported platforms.
29987 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29988 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29989 (using the read and write functions from the system runtime library is
29990 fine on UNIX but won't work under Windows).
29992 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29994 * mlib-tgt-darwin.adb: New file.
29996 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29997 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29998 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29999 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30002 * Makefile.in: Add support for building shared libraries under Darwin.
30003 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30004 the low level EH init subprogram to be called from __gnat_initialize.
30006 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30007 indicates which options to pass to the archive indexer.
30009 * mlib-utl.adb: Add support for calling ranlib with additional
30010 options. This is needed for instance under Mac OS X.
30011 (Ranlib_Options): New global variable, used to store the potential
30012 options to pass to ranlib.
30013 (Ar): Use Ranlib_Options when spawning ranlib.
30014 (Initialize): Set the value of ranlib option.
30016 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30018 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30019 instead of 8K, to reflect the real potential needs for stack-checking
30022 2004-10-26 Pascal Obry <obry@gnat.com>
30024 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30026 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30027 Windows only the initial thread stack size can be set so it is good to
30028 start we a low stack size.
30029 The OS will adjust the size as needed.
30031 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30032 Nicolas Setton <setton@act-europe.fr>
30034 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30035 "__unix__" instead of "unix".
30036 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30037 sections were just mistakenly ignored. The former is
30038 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30039 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30040 of hpux. This prevents an unwanted definition of the symbol
30041 convert_addresses in adaint.o.
30043 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30045 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30046 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30048 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30050 * a-filico.ads, a-filico.adb: fix incorrect header.
30052 2004-10-26 Javier Miranda <miranda@gnat.com>
30054 * a-ststio.ads: Fix typo in identifier
30056 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30058 * sem_ch4.adb: Minor reformatting.
30060 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30062 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30063 enabled, check the result of unary and binary operations when the
30064 expression is the right-hand side of an assignment.
30066 2004-10-26 Vincent Celier <celier@gnat.com>
30068 * clean.adb (Delete): Do not output warnings when in quiet output and
30069 not in verbose mode.
30070 (Force_Deletions): New Boolean flag, defaulted to False
30071 (Delete): Only delete a file if it is writable, and when
30072 Force_Deletions is True.
30073 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30074 (Usage): Line for new switch -f
30075 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30078 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30080 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30081 JM type only if its size matches that of the wrapper. When a size is
30082 prescribed and the field is not aliased, remove the wrapper of a JM
30083 type only if the size is not greater than that of the packed array.
30084 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30087 2004-10-26 Geert Bosch <bosch@gnat.com>
30089 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30090 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30091 (Pred): Implement in terms of Succ.
30093 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30095 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30096 unchecked conversion is safe for in-place use if the expression of the
30097 conversion is safe.
30098 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30099 be expandable in place even if the aggregate does not come from source.
30100 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30101 designated object of an allocator in place, rather than building it
30102 first on the stack. The previous scheme forces a full copy of the array,
30103 and may be altogether unsusable if the size of the array is too large
30104 for stack allocation.
30106 2004-10-26 Robert Dewar <dewar@gnat.com>
30108 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30109 compares if the component is atomic.
30111 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30112 array assignment if the component type is atomic.
30114 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30115 Eric Botcazou <ebotcazou@act-europe.fr>
30117 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30118 is aliased and is a by_reference type, do not pass by copy.
30119 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30120 detect whether the call is in the right side of an assignment or
30121 the expression of an object declaration. Recurse on component
30122 association within aggregates.
30123 Call it in the condition that determines whether the temporary is
30124 necessary for correct stack-checking.
30126 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30128 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30129 RACW_Type, used in the PolyORB version.
30130 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30131 version and the GARLIC version.
30133 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30134 Rename RCI_Info to RCI_Locator for better consistency between the
30135 GARLIC and PolyORB versions of the distributed systems annex.
30136 (DSA_Implementation_Name): This enumeration lists the possible
30137 implementations of the Partition Communication Subsystem for the
30138 Distributed Systems Annex (DSA). The three available implementations
30139 are the dummy stub implementation (No_DSA), and two versions based on
30140 two different distribution runtime libraries: GARLIC and PolyORB. Both
30141 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30143 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30146 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30147 between the GARLIC and PolyORB versions of the distributed systems
30149 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30151 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30153 * gnat1drv.adb: Suppress calling the back end when
30154 Frontend_Layout_On_Target is true.
30156 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30158 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30159 Set_Read_Only): New subprograms.
30160 These new routines allow the user to set or unset the Owner execute
30161 and Owner write permission flags on a file.
30163 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30164 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30166 2004-10-26 Matthew Gingell <gingell@gnat.com>
30168 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30170 2004-10-26 Pascal Obry <obry@gnat.com>
30172 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30173 memory before the faulting page we properly test the process read
30174 access for this address using appropriate Win32 routine.
30175 (HPUX sections): guard with "__hpux__" instead of "hpux".
30177 2004-10-26 Robert Dewar <dewar@gnat.com>
30179 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30180 entry parameter if pragma Unreferenced set, since we do not properly
30181 handle the case of multiple parameters.
30183 2004-10-26 Vincent Celier <celier@gnat.com>
30185 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30186 (Ada_Objects_Path.Add): For a library project, add to the object path
30187 the library directory only if there is no object directory or if the
30188 library directory contains ALI files.
30189 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30191 2004-10-26 Vincent Celier <celier@gnat.com>
30193 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30194 extension of library projects.
30196 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30197 path defaults to ".:<prefix>/lib/gnat".
30198 (Parse): For an extending all project, allow direct import of a project
30199 that is virtually extended.
30201 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30202 the specified name is directly imported, return its ID. Otherwise, if
30203 an extension of this project is imported, return the ID of the
30206 2004-10-26 Robert Dewar <dewar@gnat.com>
30208 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30209 (Sub3): New procedure, used by Scaled_Divide
30210 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30211 correct more than one instance of failure to propagate carries
30213 (Double_Divide): Handle overflow case of largest negative number
30214 divided by minus one.
30216 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30217 the case of a quotient value out of range.
30220 2004-10-26 Robert Dewar <dewar@gnat.com>
30222 * s-bitops.adb (Bit_Eq): Remove redundant check.
30224 * s-bitops.ads: Minor comment updates
30225 Change some occurrences of Address to System.Address
30227 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30229 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30231 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30232 accessibility check to prefix that is a protected operation.
30234 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30236 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30237 empty, post message on stub.
30239 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30240 Javier Miranda <miranda@gnat.com>
30242 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30243 current instance appears within a unit that is directly in the context
30245 Used to determine whether the body of the instance should be analyzed
30246 immediately after its spec, to make its subprogram bodies available
30247 for front-end inlining.
30248 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30249 constraint is not allowed on the component type (AARM 12.5.3(3))
30251 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30253 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30254 'Storage_Pool): enhance, document & limit detection of non-sharable
30257 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30259 * s-pooglo.ads: Add more documentation now that this pool is properly
30262 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30264 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30265 or protected type with discriminants, do not constrain the
30266 corresponding record type if the subtype declaration has no
30267 discriminant constraints. This can be the case in source code, or in
30268 the subtype declaration created to rename an actual type within an
30271 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30273 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30274 different kind of stub (possibly wrong name for file), do not check
30276 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30277 includes call to some function that returns an unconstrained type, do
30280 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30282 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30283 appear in the code for the main unit. Dependencies among units in the
30284 context of the main unit are established when those other units are
30285 compiled. Otherwise spurious elaboration constraints can generate
30286 incorrect elaboration circularities.
30288 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30289 Ed Schonberg <schonberg@gnat.com>
30291 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30292 subprogram is called with a parameter that is not an object name. This
30293 situation arises for some cases of illegal code, which is diagnosed
30294 later, and in this case it is wrong to call Is_Aliased, as that might
30295 cause a compiler crash.
30296 (Explain_Limited_Type): Refine previous fix to include
30297 inherited components of derived types, to provide complete information.
30299 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30300 is the prival for a protected object.
30301 It is necessary to mark this entity as a variable, in addition to
30302 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30303 modified to avoid checking the Aliased flag on entities that are not
30304 objects. (Checking that flag for non-objects is erroneous and could
30305 lead to a compiler crash).
30307 2004-10-26 Robert Dewar <dewar@gnat.com>
30309 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30310 X_Frac = 0.5, then we know that the number X must be positive.
30311 (Succ): Remove the same redundant test, and also fix the primary test
30312 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30314 (Decompose): Add fuller comments to spec
30316 2004-10-26 Pascal Obry <obry@gnat.com>
30318 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30319 validity (process must have read access). Set to 0 in all other cases.
30320 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30321 violation on Win32.
30322 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30323 segmentation violation.
30325 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30327 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30328 whose type is a constructed subtype of an aliased object with an
30329 unconstrained nominal subtype, convert the actual to the constructed
30330 subtype before taking its address.
30332 2004-10-26 Vincent Celier <celier@gnat.com>
30334 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30335 (Is_Path_Name_Case_Sensitive): New function
30337 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30338 (Base_Name, Simple_Name, Current_Directory, Compose,
30339 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30342 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30343 Vasiliy Fofanov <fofanov@act-europe.fr>
30344 Vincent Celier <celier@gnat.com>
30346 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30347 "memory management issues" section and document some of the useful
30348 memory pools provided as part of the GNAT library.
30349 Remove "virtual" from declaration of A::method2 in
30350 the simple example of Ada/C++ mixed system.
30351 Library Projects may be virtually extended: their virtual extensions
30352 are not Library Projects.
30353 Added section on extending project hierarchies.
30355 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30357 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30359 (__gnat_portable_spawn): Remove const.
30361 * mingw32.h (MAXPATHLEN): Check for previous definition.
30363 2004-10-17 Matthias Klose <doko@debian.org>
30365 * gnatvsn.ads: Set gnat library version to 4.0.
30367 2004-10-05 Vincent Celier <celier@gnat.com>
30369 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30371 2004-10-04 Laurent Guerby <laurent@guerby.net>
30374 * Makefile.in: Define and use RANLIB_FLAGS.
30376 2004-10-04 Pascal Obry <obry@gnat.com>
30378 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30379 other x86 platforms).
30381 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30383 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30384 in general and triggers stack alignment adjustment for thread entry
30385 points on targets where this is necessary.
30387 2004-10-04 Bernard Banner <banner@gnat.com>
30390 * Makefile.in: Add section for powerpc linux
30391 Add variant i-vxwork-x86.ads
30393 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30395 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30397 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30398 table registration calls when need be. Ensures no reference to the crt
30399 ctors symbol are issued in the SJLJ case, which avoids possible
30400 undefined symbol errors in the case of modules to be statically linked
30403 2004-10-04 Javier Miranda <miranda@gnat.com>
30405 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30406 in-line the code corresponding to subprogram Analyze_Actuals. In
30407 addition, analyze the actuals only in case of subprogram call.
30409 2004-10-04 Ed Falis <falis@gnat.com>
30411 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30413 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30415 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30416 in the documentation.
30418 2004-10-04 Robert Dewar <dewar@gnat.com>
30420 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30422 (Analyze_Block_Statement): Add circuitry to detect following dead code
30423 (Check_Unreachable_Code): Handle case of block exit
30425 2004-10-04 Robert Dewar <dewar@gnat.com>
30427 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30428 (XMatchD): Avoid warning for Logic_Error call
30430 2004-10-04 Robert Dewar <dewar@gnat.com>
30432 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30433 consider expressions buried within a procedure actual to be an actual.
30434 This caused some blowups with uses of packed slices within a procedure
30437 2004-10-04 Robert Dewar <dewar@gnat.com>
30439 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30440 longer need to be initialized to zero.
30441 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30442 initialized to zero.
30444 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30445 considered valid, even if the representation is modular. That's correct
30446 now that we no longer initialize packed modular arrays to zero.
30448 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30449 suffixes. These are now documented as the only cases in which the
30450 debugger ignores outer records.
30451 Previously, the spec allowed arbitrary suffixes for this purpose.
30452 Change name of LJM to JM for packed array pad records
30453 Create separate section on packed array handling, and add a whole new
30454 set of comments to this section describing the situation with packed
30455 modular types and justification requirements depending on endianness.
30457 2004-10-04 Robert Dewar <dewar@gnat.com>
30459 * a-except.adb: Add a comment for last change
30461 * einfo.ads: Minor spelling correction in comment
30463 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30465 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30468 * sem_util.ads: Minor comment update
30470 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30472 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30473 Inline_Always when in Configurable_Run_Time mode.
30475 * sem_prag.adb (Process_Convention): If entity is an inherited
30476 subprogram, apply convention to parent subprogram if in same scope.
30477 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30478 when in Configurable_Run_Time mode.
30480 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30482 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30483 class_wide type after component list has been inherited.
30485 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30487 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30488 Denotes_Previous_Actual, to handle properly the case of a private
30489 actual that is also the component type of a subsequent array actual.
30490 The visibility status of the first actual is not affected when the
30491 second is installed.
30492 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30493 make fully recursive the treatment of formals of packages declared
30495 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30496 the above on exit from an instantiation.
30497 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30498 current instantiation which is now complete.
30499 (Analyze_Package_Instantiation): No instantiated body is needed if the
30500 main unit is generic. Efficient, and avoid anomalies when a instance
30501 appears in a package accessed through rtsfind.
30503 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30505 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30506 do not generate a declaration for a temporary if the call is part of a
30507 library-level instantiation.
30509 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30511 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30512 searching for a limited component to flag.
30514 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30515 expansion of Input, to account for the fact that the implicit call
30516 generated by the attribute reference must freeze the user-defined
30517 stream subprogram. This is only relevant to 'Input, because it can
30518 appear in an object declaration, prior to the body of the subprogram.
30520 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30521 expansion can proceed and further errors uncovered.
30522 (Minor clean up): Fix cases of using | instead of \ for continuation
30525 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30527 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30529 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30530 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30531 Use gcc_assert and gcc_unreachable.
30533 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30534 specified alignment before validating size.
30535 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30536 stripped-down declaration for the type of the inner field when making
30539 * utils.c (finish_record_type): Do not compute the size in units
30540 incrementally. Instead compute it once for the rep clause case.
30541 Use gcc_assert and gcc_unreachable.
30543 2004-10-04 Vincent Celier <celier@gnat.com>
30545 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30547 (Is_Valid_Path_Name): Take '/' as a directory separator.
30549 2004-10-04 Vincent Celier <celier@gnat.com>
30551 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30552 (Extended_Project) only if Extended_Project is defined, to avoid
30554 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30556 (Parse_Single_Project): Ditto.
30558 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30559 Add_To_Project_Path for virtual projects.
30561 2004-10-04 Vincent Celier <celier@gnat.com>
30563 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,

30565 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30566 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30567 parameter Options_2.
30569 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30570 Build_Dynamic_Library with an empty Options_2.
30572 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30575 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30576 directory separator, if any.
30577 (Gprmake): Do not allow mains on the command line for library projects.
30578 Do not attempt to link when the project is a library project.
30579 (Library_Opts): New table to store Library_Options.
30580 (Build_Library): If Library_Options is specified, pass these options
30581 when building a shared library.
30583 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30585 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30586 the end of this procedure now that the unlock operation was inserted
30589 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30591 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30592 corresponding to the Preallocated_Stacks flags in System.
30593 (Get_Target_Parameters): Including the processing for
30594 Preallocated_Stacks.
30596 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30597 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30600 system-vxworks-sparcv9.ads, system-vxworks-xscale.ads,
30601 system-solaris-x86.ads, system-irix-o32.ads, system-irix-n32.ads,
30602 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30603 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30604 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30605 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30606 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30607 used to signal whether the compiler creates the required stacks and
30608 descriptors for the different tasks (when True) or it is done by the
30609 underlying operating system at run time (when False).
30610 It is initially set to False in all targets.
30612 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30613 if it is supported by the target.
30614 (Make_Task_Create_Call): Pass the stack address if it has been
30615 previously created. Otherwise pass a Null_Address.
30617 * snames.adb: Add _stack.
30619 * snames.ads: Add Name_uStack. Required to allow the expander to
30620 statically allocated task stacks.
30622 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30623 Stack_Address argument.
30624 Check that its value is equal to Null_Address because this target does
30625 not support the static stack allocation.
30627 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30629 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30632 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30634 * exp_dist.adb: Split declaration of asynchronous flag out of
30635 Add_RACW_Read_Attribute.
30636 Minor reformatting for better alignment with PolyORB version.
30637 Store the entity for the asynchronous flag of an RACW, rather than the
30638 expression, in the asynchronous flags table. This will allow this flag
30639 to be used in other subprograms beside Add_RACW_Read_Attribute.
30641 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30643 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30644 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30645 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30646 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30647 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30648 sockets constant MSG_NOSIGNAL (Linux-specific).
30649 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30650 all Send operations.
30651 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30652 from trigerring SIGPIPE.
30653 Rename components to avoid clash with Ada 2005 possible reserved
30655 (Check_Selector): When the select system call returns with an error
30656 condition, propagate Socket_Error to the caller.
30658 2004-10-01 Jan Hubicka <jh@suse.cz>
30660 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30662 2004-09-23 Robert Dewar <dewar@gnat.com>
30665 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30666 instead do this at freeze time (we won't do it if there is an address
30668 Change "pragma inline" to "pragma Inline" in information and error
30670 Minor reformatting.
30672 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30673 right way of doing things after all.
30674 (Freeze_Entity): For object, set Is_Public for imported entities
30675 unless there is an address clause present.
30677 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30679 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30680 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30681 ensures proper handling of types with rep clauses, which might have
30682 their TYPE_SIZE set already.
30684 2004-09-21 Robert Dewar <dewar@gnat.com>
30686 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30687 packed array types in both little- and big-endian cases. This change
30688 ensures that we no longer count on the unused bits being initialized
30689 for such types (and in particular ensures that equality testing will
30690 only read the relevant bits).
30691 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30692 These changes mean that we no longer need to initialize small packed
30694 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30695 optimization to an LJM field as to its parent field.
30697 * ada-tree.h, trans.c, utils.c, utils2.c:
30698 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30700 2004-09-20 Jan Hubicka <jh@suse.cz>
30702 * utils.c (gnat_finalize): Remove.
30703 (end_subprog_body): Directly call cgraph_finalize_function;
30704 do not lower the nested functions.
30706 2004-09-20 Robert Dewar <dewar@gnat.com>
30709 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30710 if an address clause is present, since that means that the Import
30713 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30715 * 5tsystem.ads: Removed, no longer used.
30717 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30718 Zack Weinberg <zack@codesourcery.com>
30720 * ada-tree.def: Use tree_code_class enumeration constants
30721 instead of code letters.
30722 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30723 Update for new tree-class enumeration constants.
30725 2004-09-17 Vincent Celier <celier@gnat.com>
30727 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30728 capabilities of the general project manager.
30730 2004-09-09 Vincent Celier <celier@gnat.com>
30732 * a-direct.ads: Add pragma Ada_05
30733 (Directory_Entry_Type): Give default value to component Kind to avoid
30734 not initialized warnings.
30736 * a-direct.adb (Current_Directory): Remove directory separator at the
30738 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30739 an existing directory.
30740 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30741 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30742 Convert the result to File_Size.
30744 * prj.ads: (Project_Error): New exception
30746 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30747 Prj.Com, not from Osint.
30748 (Attrs, Package_Attributes): Tables moved to private part of spec
30749 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30751 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30752 Prj.Project_Error after call to Fail.
30753 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30754 Fail. Check that package name is not already in use.
30756 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30757 used by tools, not only by the project manager, and to indicate that
30758 exception Prj.Prj_Error may be raised in case of problem.
30759 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30761 (Attrs, Package_Attributes): Table instantiations moved from the body to
30762 the private part to be accessible from Prj.Attr.PM body.
30764 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30765 from new package Prj.Attr.PM.

30822 raise Program_Error if called from a protected operation.
30824 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30825 the protected action nesting level.
30826 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30827 protected action nesting level.
30828 (Unlock): When pragma Detect_Blocking is active decrease the protected
30829 action nesting level.
30831 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30832 Protected_Action_Nesting.
30834 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30835 Common_ATCB record. It contains the dynamic level of protected action
30836 nesting for each task. It is needed for checking whether potentially
30837 blocking operations are called from protected operations.
30838 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30839 Detect_Blocking is active or not in the partition.
30841 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30875 contains the required machinery for handling that.
30877 * sem_util.ads: Change comment associated to procedure
30878 Check_Potentially_Blocking_Operation.
30879 This procedure does not insert a call for raising the exception because
30880 that is currently done by the run time.
30882 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30884 * init.c: Add the global variable __gl_detect_blocking that indicates
30885 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30886 making the pragma available at run time.
30887 (__gnat_set_globals): Pass and update the detect_blocking parameter.

30890 pragma Detect_Blocking is active.
30892 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30894 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30895 DB is found in the ali file. Any unit compiled with pragma
30896 Detect_Blocking active forces its effect in the whole partition.
30898 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30899 Detect_Blocking is active and delay is called from a protected
30902 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30903 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30904 Detect_Blocking is active (0 otherwise).
30905 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30906 as Detect_Blocking parameter if pragma Detect_Blocking is active (0

30916 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30917 Update API in placeholder implemetation of s-parint to reflect changes
30918 in distribution runtime library.
30920 * sem_ch3.adb (Expand_Derived_Record): Rename to
30921 Expand_Record_Extension.
30923 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30924 primitive operations of potentially distributed object types that have
30925 non-controlling anonymous access formals.
30927 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30929 New implementation of expansion for remote access-to-subprogram types,
30930 based on the RACW infrastructure.
30931 This version of sem_dist is compatible with PolyORB/DSA as well as
30934 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30935 Asynchrronous that applies to a remote access-to-subprogram type, mark
30936 the underlying RACW type as asynchronous.
30938 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30939 __gnat_using_gnu_linker to 1.

30949 Expand_Record_Extension.
30950 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30951 a component declaration must remain attached at that point in the
30952 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30953 It is therefore necessary to take a copy of the expression when building
30954 the corresponding assignment statement in the init proc.
30955 As a side effect, in the case of a derived record type, we now see the
30956 original expression, without any rewriting that could have occurred
30957 during expansion of the ancestor type's init proc, and we do not need
30958 to go back to Original_Node.
30960 * exp_ch3.ads (Expand_Derived_Record): Rename to

30968 subprogram. The proxy object is used as the designated object
30969 for RAS values on the same partition (unless All_Calls_Remote applies).
30970 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30971 System.Partition_Interface.Get_Unique_Remote_Pointer.

30976 New implementation of expansion for remote access-to-subprogram types,
30977 based on the RACW infrastructure.
30979 * exp_dist.ads (Copy_Specification): Update comment to note that this
30980 function can copy the specification from either a subprogram
30981 specification or an access-to-subprogram type definition.
30983 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30985 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30986 in an instance, between an explicit subprogram an one inherited from a
30987 type derived from an actual.
30989 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30990 add a polling call if the subprogram is to be inlined by the back-end,
30991 to avoid repeated calls with multiple inlinings.
30993 * checks.adb (Apply_Alignment_Check): If the expression in the address
30994 clause is a call whose name is not a static entity (e.g. a dispatching
30995 call), treat as dynamic.

30999 * g-trasym.ads: Minor reformatting
31001 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31012 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31013 enable map file generation. Add the right option to generate the map
31014 file if Map_File is set to True.
31016 * gnatdll.adb (Gen_Map_File): New variable.
31017 (Syntax): Add info about new -m (Map_File) option.

31045 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31046 of variable length temporaries for function return now that the
31047 back-end and gigi support it.

31098 * exp_ch6.adb (Expand_Call): Properly handle validity checks for
31099 packed indexed component where array is an IN OUT formal. This
31100 generated garbage code previously.

31119 expander is not active (but check for unset reference to prefix of
31122 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31123 pragma Debug as an if statement with a constant condition, for
31124 consistent treatment of entity references contained within the
31125 enclosed procedure call.
31127 2004-09-01 Vincent Celier <celier@gnat.com>
31129 * bindgen.adb: (Set_EA_Last): New procedure
31130 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure

31154 2004-09-01 Pascal Obry <obry@gnat.com>
31156 * gprcmd.adb (Extend): Do not output trailing directory separator. This

31161 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31162 target names rewrite to fix regressions with recent version of

31214 2004-08-16 Pascal Obry <obry@gnat.com>
31216 * adaint.c (__gnat_prj_add_obj_files): Set to 0 only on Win32 for GCC
31217 backend prior to GCC 3.4. With GCC 3.4 we are using the GCC's shared
31218 option and not mdll anymore. Update comment.
31220 2004-08-16 Pascal Obry <obry@gnat.com>
31222 * bld.adb (Put_Include_Project): Properly handle directory separators
31225 2004-08-16 Ed Schonberg <schonberg@gnat.com>

31238 2004-08-13 Olivier Hainque <hainque@act-europe.fr>
31240 * decl.c (gnat_to_gnu_entity) <E_Variable>: When building an allocator
31241 for a global aliased object with a variable size and an unconstrained
31242 nominal subtype, pretend there is no initializer if the one we have is
31243 incomplete, and avoid referencing an inexistant component in there. The
31244 part we have will be rebuilt anyway and the reference may confuse
31245 further operations.

33227 * lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
33228 includes case of a variable referenced on the left hand side of an
33229 assignment, therefore remove redundant code. Variables and prefixes of

33231 hand side. Warnings are now properly emitted when variables or prefixes
33232 are assigned but not read.

33239 "variable ... is assigned but never read" since other entities may read
33240 the memory location.

33896 Merge from tree-ssa-20020619-branch.
33898 * config-lang.in (boot_language, build_by_default): Set

33935 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33936 Analyze on the library unit node after generation of distribution stub
33937 constructs. The call was a no-op because Unit_Node has already been
33938 Analyzed, and the tree fragments for the distribution stubs are
33939 analyzed as they are inserted in Exp_Dist.
33940 Update comment regarding to distribution stubs to reflect that we
33941 do not generate stub in separate files anymore.

33959 has been rewritten as an explicit dereference, retrieve type of
33960 original node to check for possibly unconstrained record type.
33962 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33964 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33965 overriding, use the operation of the parent unconditionally.
33967 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33968 operation when either operand is a literal, to avoid further
33971 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33972 overridden by a previous explicit declaration, mark the previous entity
33975 * sem_disp.adb (Check_Dispatching_Operation): New predicate
33976 Is_Visibly_Controlled, to determine whether a declaration of a
33977 primitive control operation for a derived type overrides an inherited
33978 one. Add warning if the explicit declaration does not override.
33980 2004-05-10 Vincent Celier <celier@gnat.com>
33982 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
33983 some cases when the sources are no longer present.
33985 * make.adb (Collect_Arguments): Fail if an external source, not part
33986 of any project need to be compiled, when switch -x has not been
33989 * makeusg.adb: Document new switch -x
33991 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
33992 defaulted to False.

33996 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
33997 gnatmake switch -x.
33999 * gnat_ugn.texi: Document new gnatmake switch -x
34001 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
34003 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34005 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34006 (process_attributes): Likewise.
34008 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34010 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34012 2004-05-10 Robert Dewar <dewar@gnat.com>
34014 * gnat_ugn.texi: Document that for config pragma files, the maximum
34015 line length is always 32767.
34017 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34018 literals is now allowed.
34020 * gnat-style.texi: Remove statement about splitting long lines before
34021 an operator rather than after, since we do not follow this rule at all.
34022 Clarify rule (really lack of rule) for spaces around exponentiation
34024 * sem_elim.adb: Allow concatenation of string literals as well as a
34025 single string literal for pragma arguments.
34027 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34029 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34030 written for append case.
34032 * frontend.adb: Changes to avoid checking max line length in config
34035 * g-os_lib.ads: Minor reformatting
34037 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34038 wrong in any case. Instead use standard value. Noticed during code
34041 * opt.ads (Max_Line_Length): New field, used to implement removal of
34042 limitation on length of lines when scanning config pragma files.
34044 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34045 makeutl.ads, makeutl.adb: Minor reformatting
34047 * scn.adb: Do not check line length while scanning config pragma files

35236 as is done for non-private derived record types.
35238 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35239 Ada 2005 AI-310: an abstract non-dispatching operation is not a

35254 complete assignment subtree which is now unnecessary, as the expansion
35255 of inlined call has been improved to preserve a consistent assignment
35256 tree. Note_Possible_Modification must be called only
35257 after checks have been applied, or else unnecessary checks will
35260 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35261 of explicit dereferences that do not Come_From_Source:

35263 pointer (an assignment to an implicit dereference must not be
35264 recorded as modifying the pointer);
35265 - do not rely on Original_Node being present (Analyze_Assignment
35266 calls Note_Possible_Modification on a copied tree).
35268 * sem_warn.adb (Check_References): When an unset reference to a pointer
35269 that is never assigned is encountered, prefer '<pointer> may be null'
35270 warning over '<pointer> is never assigned a value'.

35533 information for protected (wrapper) operation as well, to simplify gdb
35536 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a

35579 a classwide type (for which Is_Object_Reference holds), but it can
35580 also be a value conversion for an access-to-classwide type. In the
35581 latter case, there is an implicit dereference, and the original node
35582 for the prefix does not verify Is_Object_Reference.

35668 gigi has enough information to construct the record, and there is no
35669 place in the tree for the declaration.
35671 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35672 serial number for the dummy body that is built for analysis, to avoid
35673 inconsistencies in the generation of internal names when compiling
35676 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35678 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35681 2004-03-22 GNAT Script <nobody@gnat.com>
35683 * Make-lang.in: Makefile automatically updated
35685 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35687 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
35688 * trans.c (tree_transform, emit_index_check): Likewise.
35689 * utils.c (build_template): Likewise.
35690 (max_size, convert): Remove handling of WITH_RECORD_EXPR.

35710 Minor reformatting.
35712 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35714 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35715 as regular exception objects and not as mere integers representing the
35716 condition code. The latter approach required some dynamics to mask off
35717 severity bits, which did not fit well into the GCC table based model.
35718 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35719 exception data objects. We don't it and it would conflict with the other
35720 external symbol we have to generate for such exceptions.
35722 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35723 the special code for VMS exceptions, since these are now represented
35724 as regular exceptions objects.
35726 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35728 * decl.c (debug_no_type_hash): Remove.

35732 2004-03-19 Laurent Guerby <laurent@guerby.net>
35734 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35735 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35737 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35739 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35740 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.

35743 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35744 TYPE_VALUES, not TYPE_FIELDS.

35757 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35759 * adaint.c: Update comments.
35761 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35762 GNATLIB_SHARED for FreeBSD.
35764 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35766 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35767 When needed (stack checking) the stack size is retrieved
35768 from the VxWorks kernel.
35770 * Makefile.in: Flag -nostdinc is required when building the run time
35771 for avoiding looking for files in the base compiler.
35772 Add the VxWorks specific version of the package body for
35773 System.Stack_checking.Operations (5zstchop.adb).
35775 * Make-lang.in: Add the object file for
35776 System.Stack_Checking.Operations.

35784 checking from this package to package System.Stack_Checking.Operations.
35785 This way, stack checking operations are only linked in the final
35786 executable when using the -fstack-check flag.
35788 2004-03-18 Doug Rupp <rupp@gnat.com>
35790 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35800 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35801 the procedures Add_To_Path_File.
35802 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35803 making sure that each directory is present only once and, for object
35804 dirs, when a directory already present is added, the duplicate is
35805 removed and the directory is always put as the last in the table.
35806 Write the path files at the end of these accumulations.
35808 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35809 Files_Htable for all sources.
35811 * prj-proc.adb (Process): Remove restrictions between not directly
35812 related extending projects.

35820 parameter Trusted_Mode.
35822 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35824 * scn.adb (Determine_License): Take into account a degenerated case
35825 when the source contains only comments.
35827 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35829 * sem_warn.adb (Check_References): For a warning on a selected
35830 component that does not come from source, locate an uninitialized
35831 component of the record type to produce a more precise error message.
35833 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35835 * 3zsoccon.ads: Fix multicast options.
35837 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35840 2004-03-15 Robert Dewar <dewar@gnat.com>

35843 pragma used for a private type.
35845 * lib-xref.adb (Generate_Reference): Do not generate warning if
35846 reference is in a different unit from the pragma Unreferenced.
35848 * 5vtpopde.adb: Minor reformatting
35849 Fix casing of To_Task_ID
35851 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35852 flag if we have an unchecked conversion to an access type in the same
35855 2004-03-15 Geert Bosch <bosch@gnat.com>
35857 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35858 imaginary parts, use Double precision throughout.
35860 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35861 we want to be able to compile run-time with -gnata for testing, but
35862 this may also be instantiated in user code that is compiled with -gnata.
35864 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35866 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

35868 throughout the various run-time units.
35869 (Exception_Data): Use Exception_Code for Import_Code.
35871 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35879 component, now reflected by an exported accessor.
35880 (is_handled_by): New routine to compute whether the propagated
35881 occurrence matches some handler choice specification. Extracted out of
35882 get_action_description_for, and expanded to take care of the VMS
35884 (get_action_description_for): Use is_handled_by instead of an explicit
35885 complex condition to decide if the current choice at hand catches the
35886 propagated occurrence.
35888 * raise.h (Exception_Code): New type for C.
35890 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35891 System.Standard_Library.Exception_Code, to allow references from the
35892 pragma import/export expander.
35894 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35895 New accessors to allow easy access to GNAT exception data
35897 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35898 redundant Handled_By_Others component, helper for the personality
35899 routine which will now be able to call the appropriate exception data
35902 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35903 component of Standard_Exception_Type to be the closest possible to
35904 Exception_Code in System.Standard_Library, that we cannot get at this
35905 point. Expand a ??? comment to notify that this type node should
35906 probably be rewritten later on.
35908 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35909 registration call to include a pointer to the exception object in the
35912 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35913 instead of int and explicit bitmasks.
35915 2004-03-15 Vincent Celier <celier@gnat.com>
35917 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35918 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35920 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35921 longer needed now that it is in the spec of
35922 System.Tasking.Task_Attributes.
35924 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35926 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35928 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35930 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35931 taken care of in Scan_Make_Arg.
35932 (Scan_Make_Arg): Add the executable suffix only if the argument
35933 following -o, in canonical case, does not end with the executable
35934 suffix. When in verbose mode and executable file name does not end
35935 with executable suffix, output the executable name, in canonical case.
35937 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35938 to avoid warnings when instantiating Ada.Task_Attributes.
35941 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35942 in the correct order.
35944 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35952 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35954 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35955 tagged type is inherited, and the parent operation is not frozen yet,
35956 force generation of a freeze node for the inherited operation, so the
35957 corresponding dispatch entry is properly initialized.
35958 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35959 when looking for user-defined equality operation.
35961 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35962 boolean when locating primitive equality of tagged component.
35964 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35966 a temporary before expanding assignment into a loop.
35968 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35969 priority in full, to ensure that any expanded subepxressions of it are
35970 elaborated in the scope of the init_proc.

35973 after object declaration, skipping over code that may have been
35974 generated for validity checks.
35976 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35977 discriminants, ignore the known discriminants of its full view, if
35978 any, to check legality.
35980 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35981 component if type has unknown discriminants.
35982 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35983 null if type has unknown discriminants.
35985 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35986 for end label when present.
35988 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35989 temporary file, rather than an empty string.
35991 2004-03-15 Ed Falis <falis@gnat.com>
35993 * s-thread.adb: Removed, no longer used.

36015 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36016 Insert_Dereference_Action when rewriting an implicit dereference into
36017 an explicit one, this will be taken care of during expansion of the
36018 explicit dereference.
36019 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36020 of non-packed slices, since the dereference action generated by
36021 expansion of the explicit dereference is needed in any case.
36022 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36023 analyze and resolve the rewritten explicit dereference so it is seen
36025 (Insert_Dereference_Action): This procedure is now called only for the
36026 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36027 dereferences that do not come from source (including explicit
36028 dereferences resulting from rewriting implicit ones), but do not
36029 recursively insert a check for the dereference nodes contained within
36031 (Insert_Dereference_Action): Clarify and correct comment.

36908 checks for bitfield creation are triggered.
36909 (finish_record_type): During last pass over the fields, clear
36910 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37297 be modified by the binder generated main program if the -D switch is
37300 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37301 imported functions (since now we expect this to be done for imported
37304 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37305 Minor reformatting throughout
37307 * 5zinit.adb: Minor reformatting

37311 doing reformatting)
37313 * sprint.adb: Minor updates to avoid -gnatwa warnings
37315 * s-secsta.ads, s-secsta.adb:
37316 (SS_Get_Max): New function to obtain high water mark for ss stack
37317 Default_Secondary_Stack is not a constant since it may be modified by
37318 the binder generated main program if the -D switch is used.
37320 * switch-b.adb: New -Dnnn switch for binder
37323 Make -gnatg imply all warnings currently in -gnatwa

37354 Acquire new SS indication of secondary stack use from ali files
37356 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37357 (since now we expect this to be done for imported functions)
37359 * bindgen.adb: Generate call to modify default secondary stack size if
37362 * bindusg.adb: Add line for new -D switch
37364 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37365 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37366 Add circuitry for both records and arrays to avoid gigi
37367 processing if the type involved has non-bit-aligned components
37369 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37370 N_String_Literal node always references an E_String_Literal_Subtype
37371 entity. This may not be true in the future.
37372 (Possible_Bit_Aligned_Component): Move processing of
37373 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37375 * exp_ch6.adb (Expand_Thread_Body): Pick up
37376 Default_Secondary_Stack_Size as variable so that we get value modified
37377 by possible -Dnnn binder parameter.
37379 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37380 (Type_May_Have_Bit_Aligned_Components): New function.
37382 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37392 unless explicit Pure_Function pragma given, to avoid insidious bug of
37393 call to non-pure imported function getting eliminated.

37415 * rtsfind.adb (Load_Fail): Give full error message in configurable
37416 run-time mode if all_errors mode is set. This was not done in the case
37417 of a file not found, which was an oversight.
37418 Note if secondary stack unit is used by compiler.
37420 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37421 ineffective elaborate all pragmas on non-visible packages (this
37422 happened when a renamed subprogram was called). Now the elaborate all
37423 always goes on the package containing the renaming rather than the one
37424 containing the renamed subprogram.
37426 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37427 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37429 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37430 has an Etype that references an E_String_Literal.
37431 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37432 always references an E_String_Literal_Subtype entity. This may not
37433 be true in the future.
37435 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37438 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37441 2004-01-05 Ed Falis <falis@gnat.com>

37448 * bld.adb: Minor comment updates
37449 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37452 * make.adb (Gnatmake): Special process for files to compile/check when
37453 -B is specified. Fail when there are only foreign mains in attribute
37454 Main of the project file and -B is not specified. Do not skip bind/link
37455 steps when -B is specified.
37457 * makeusg.adb: Document new switch -B
37459 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
37461 * switch-m.adb: (Scan_Make_Switches): Process -B switch

37480 -gnatwa warning on static condition.
37482 2004-01-05 Doug Rupp <rupp@gnat.com>

37486 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37488 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37489 all attributes, including read-only attribute.
37491 2004-01-05 Pascal Obry <obry@gnat.com>

37494 library naming scheme.
37496 * mlib-prj.adb (Build_Library): Generate different names for the static
37497 or dynamic version of the GNAT runtime. This is needed to support the
37498 new shared library naming scheme.

37500 based on the new naming scheme.
37502 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37503 scheme for the shared runtime libraries.
37506 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37508 (install-gnatlib): Do not create symlinks for shared libraries.
37509 (gnatlib-shared-default): Idem.
37510 (gnatlib-shared-dual-win32): New target. Not used for now as the
37511 auto-import feature does not support arrays/records.
37512 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37513 (gnatlib-shared-vms): Fix shared runtime libraries names.
37515 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37516 dependent runtime shared library name.
37518 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37520 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37523 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37525 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37526 protected objects when allocator has a subtype indication, not a
37527 qualified expression. Note that qualified expressions may have to be
37528 checked when limited aggregates are implemented.
37530 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37531 pure, emit warning.
37532 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37533 subprogram is imported, remove warning.
37535 2004-01-05 Geert Bosch <bosch@gnat.com>
37537 * s-poosiz.adb: Update copyright notice.
37538 (Allocate): Use Task_Lock to protect against concurrent access.
37539 (Deallocate): Likewise.
37541 2004-01-05 Joel Brobecker <brobecker@gnat.com>
37543 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

37577 * cstand.adb (Create_Standard): Change the way how the declaration of
37578 the Duration type is created (making it the same way as it is for all
37579 the other standard types).
37581 2003-12-17 Robert Dewar <dewar@gnat.com>
37583 * s-crtl.ads: Fix header format
37584 Change Pure to Preelaborate

37589 the expression type only if it is declared in the current unit.
37591 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37592 are universal and already analyzed, as can occur in constrained
37593 subcomponents that depend on discriminants, when one constraint is a
37596 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37597 type Any_Fixed is legal as the argument of a conversion, if only one
37598 fixed-point type is in context.

37611 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37612 (Gnatchop): Do not set failure status when reporting the number of
37615 2003-12-15 Doug Rupp <rupp@gnat.com>
37617 * s-ctrl.ads: New file.
37619 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).

37637 * Make-lang.in: Makefile automatically updated
37639 2003-12-11 Ed Falis <falis@gnat.com>
37641 * 5zinit.adb: Clean up.
37643 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37644 to __gnat_map_signal, imported from init.c to support

37677 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37678 Minor reformatting throughout
37680 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37682 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37683 bounds of a loop, create a separate block in order to generate proper
37684 cleanup actions to prevent memory leaks.
37686 * sem_res.adb (Resolve_Call): After a call to
37687 Establish_Transient_Scope, the call may be rewritten and relocated, in
37688 which case no further processing is needed.
37690 * sem_util.adb: (Wrong_Type): Refine previous fix.
37691 Fixes ACATS regressions.
37694 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37697 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37699 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37700 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37703 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37706 2003-12-08 Robert Dewar <dewar@gnat.com>
37708 * 7sintman.adb: Minor reformatting
37710 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37711 standard linker options to get standard libraries linked. We now plan
37712 to provide dummy versions of these libraries to match the appropriate
37713 configurable run-time (e.g. if a library is not needed at all, provide
37714 a dummy empty library).
37716 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37717 options (-L parameters and standard libraries). What we plan to do is
37718 to provide dummy libraries where the libraries are not required.
37720 * gnatbind.adb: Minor comment improvement
37722 2003-12-08 Javier Miranda <miranda@gnat.com>
37724 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37725 aggregate in the parent. Otherwise constants with limited aggregates
37726 are not supported. Add new formal to pass the component type (Ctype).
37727 It is required to call the corresponding IP subprogram in case of
37728 default initialized components.
37729 (Gen_Assign): In case of default-initialized component, generate a
37730 call to the IP subprogram associated with the component.
37731 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37732 of aggregate with default initialized components.
37733 (Has_Default_Init_Comps): Improve implementation to recursively check
37734 all the present expressions.
37736 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37737 to indicate that the initialization call corresponds to a
37738 default-initialized component of an aggregate.
37739 In case of default initialized aggregate with tasks this parameter is
37740 used to generate a null string (this is just a workaround that must be
37741 improved later). In case of discriminants, this parameter is used to
37742 generate a selected component node that gives access to the discriminant
37745 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37746 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37747 allocated aggregates with default-initialized components.
37749 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37750 the box notation is used in positional aggregates.

37766 * prj-part.adb (With_Record): New component Node
37767 (Parse): New Boolean parameter Store_Comments, defaulted to False.
37768 Set the scanner to return ends of line and comments as tokens, if
37769 Store_Comments is True.
37770 (Pre_Parse_Context_Clause): Create the N_With_Clause nodes so that
37771 comments are associated with these nodes. Store the node IDs in the
37773 (Post_Parse_Context_Clause): Use the N_With_Clause nodes stored in the
37775 (Parse_Single_Project): Call Pre_Parse_Context_Clause before creating
37776 the N_Project node. Call Tree.Save and Tree.Reset before scanning the
37777 current project. Call Tree.Restore afterwards. Set the various nodes
37778 for comment storage (Next_End, End_Of_Line, Previous_Line,
37781 * prj-part.ads (Parse): New Boolean parameter Store_Comments,
37782 defaulted to False.
37784 * prj-pp.adb (Write_String): New Boolean parameter Truncated, defaulted
37785 to False. When Truncated is True, truncate the string, never go to the
37787 (Write_End_Of_Line_Comment): New procedure
37788 (Print): Process comments for nodes N_With_Clause,

39531 a subunit is missing.
39532 (Instantiate_Subprogram_Body): If body of function is missing, set type
39533 of return expression explicitly in dummy body, to prevent cascaded
39534 errors when a subunit is missing.
39538 (Access_Subprogram_Declaration): Verify that return type is valid.
39542 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39547 (Corresponding_Discriminant): If the scope of the discriminant is a
39548 private type without discriminant, use its full view.

41574 function approach did not work well because of a side effect (the
41575 function call could reallocate the table which was being indexed
41576 using its result). Fixes ada/4851.

41943 2001-12-17 Laurent Pautet <pautet@gnat.com>
41946 Fix comment of Shutdown_Socket and Close_Socket. These functions
41947 should not fail silently because if they are called twice, this
41948 probably means that there is a race condition in the user program.
41949 Anyway, this behaviour is consistent with the rest of this unit.
41950 When an error occurs, an exception is raised with the error message
41951 as exception message.

43285 instead of the previous simple checksum algorithm.
43286 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43287 (Set_Source_Table): idem.
43290 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43291 instead of simple checksum.
43292 (CRC_Match): new function.
43293 (CRC_Error): new constant.
43295 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43296 a CRC now and not a simple checksum. A CRC uses lower-case hex
43297 letters, fixes ambiguity in parsing.
43299 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43300 is what this variable will store.
43302 * bcheck.adb: Change reference to chechsum in comments by CRC.
43303 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43304 rename All_Checksum_Match to All_CRC_Match. Change due to API
43305 renaming since now GNAT does not use a simple checksum but a
43306 CRC using GNAT.CRC32.
43308 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43309 now and not anymore a simple checksum.

43346 Update comments for the CRC.
43348 * types.adb (Hex): Use lowercase for the letter part.
43350 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43351 for a word. This is currently used only for CRC. In previous version,
43352 the checksum was using a representation with all letter being
43353 upper-case. With the new implementation (using CRC) we do not remove
43354 the 32th bit of the CRC, so we can have an upper-case starting letter
43355 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43356 It is ambigous since the CRC was optional and could be followed by
43357 options like EB, EE. So now this routines uses lower-case letter for
43358 the hexadecimal representation. Strange enough only lower case letters
43359 where checked in Scan_ALI (even if this was not a possible case).
43361 * gnatvsn.ads (Library_Version): changed to 3.15a.
43363 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43366 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
