2059 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2060 Orig_Prev to Prev in the case where the actual is N_Function_Call or
2061 N_Identifier. This was interfering with other cases that are rewritten

4155 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4156 convention from its base type, do not set the type to that of integer,

4221 the visible part of the spec of a remote types unit.

4223 New local subprogram Is_Valid_Remote_Object_Type, replaces
4224 Is_Recursively_Limited_Private.
4225 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4226 non-controlling formals (and the return type, even though this is not
4227 explicit in the standard) must support external streaming.

4229 as above for of RAS types and RCI subprograms. (The return type is not

4234 * sem_util.ads, sem_util.adb
4235 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4236 Is_Remote_Call_Interface to identify RACW types in a stable and
4237 consistent way. We used to rely in this predicate on the privateness of
4238 the designated type and its ancestors, but depending on the currently
4239 visible private parts, this caused false negatives. We now uniformly
4240 rely on checks made at the point where the RACW type is declared.

4254 Add missing escaping of all-caps word 'CPP' in error messages.
4255 (Build_Discriminated_Subtype): Do not inherit representation clauses
4256 from parent type if subtype already carries them, because they are
4257 inherited earlier during derivation and already include those that may
4258 come from a partial view.
4260 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4261 Check the declarations of a subprogram body for proper deferred
4262 constant completion.

4295 (Add_One_Interp): Ignore any interpretation that is a primitive
4296 operation of an RACW stub type (these primitives are only executed
4297 through dispatching, never through static calls).
4298 (Collect_Interps): When only one interpretation has been found, set N's
4299 Entity and Etype to that interpretation, otherwise Entity and Etype may
4300 still refer to an interpretation that was ignored by Add_One_Interp,
4301 in which case would end up with being marked as not overloaded but with
4302 an Entity attribute not pointing to its (unique) correct interpretation.
4304 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4307 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4317 (Print_Itype): Do not modify the sloc of the component type of a
4318 (packed) array itype, because it is an unrelated type whose source
4319 location is independent of the point of creation of the itype itself.

4355 => null". Add clarifying ".all", even though implicit .all is legal
4358 2008-05-20 Arnaud Charlet <charlet@adacore.com>
4360 * s-winext.ads: Replace representation clause by pragma Pack. Gives
4361 equivalent representation, but has the advantage of allowing
4362 compilation of this file under 64 bits platforms.
4364 * s-os_lib.adb (Normalize_Pathname): Mark Cur_Dir constant.
4366 * s-osinte-irix.ads: (Alternate_Stack_Size): Add dummy declaration.

8562 WITH clause on a private sibling.
8563 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8564 child unit is a renaming, create an implicit with_clause on that

8667 perform subtype conformance between the formals of the current entry
8668 and those of the target interface primitive.
8669 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8670 Timed_Entry_Call): Analyze the triggering statement as the first step of
8671 the processing. If this is a dispatching select, postpone the analysis
8672 of all select statements until the Expander transforms the select. This

8674 replicated some of the select statements. In case the Expander is
8675 disabled, perform regular analysis.
8676 (Check_Triggering_Statement): New routine.
8677 (Analyze_Requeue): Exclude any interpretations that are not entries when
8678 checking overloaded names in a requeue. Also test type conformance for

9271 a predefined entity (as happens for array index types), the line is set
9273 Add support for parsing multiple array index types info, or
9274 multiple inherited interfaces info. This information cannot be stored
9275 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9291 Dismukes). After this patch there is no need to perform any
9292 additional management on these nodes in Expand_Interface_Actuals.
9294 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9295 that handles use of 'Access and 'Unchecked_Access applied to
9296 actuals covering interface types. Such code is now
9297 centralized in Expand_N_Attribute_Reference.
9299 2007-10-15 Ed Schonberg <schonberg@adacore.com>

9302 of tagged types whose ultimate ancestor is a CPP type.

9333 * vx_stack_info.c: New file.
9335 * i-forbla-unimplemented.ads: New file.
9337 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
9338 for unsupported configurations; use it on VMS targets instead of the

9341 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9342 used by VxWorks targets to have access to task-specific data and be
9343 able to extract the stack boundaries for stack checking.
9344 Use system-vms-ia64.ads on ivms.

9387 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9388 association for an access component, add an association with null as
9389 the expression. Remove testing for array subtypes and the setting in
9390 that case of Ctyp to the array component type, which prevented proper
9391 inclusion of an association for null-initialized arrays. Collapse
9392 condition that tests for array subtypes into just a test of
9393 Is_Partially_Initialized_Type (which already covers arrays anyway).
9395 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

9405 flag of derived concurrent types, taking into account the flag setting
9406 on the parent subtype and any new set of discriminants.
9408 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9410 * sem_ch4.adb: Minor code and comment reformatting.
9411 (Analyze_Allocator): When the designated type of an unconstrained
9412 allocator is a record with unknown discriminants or an array with
9413 unknown range bounds, emit a detailed error message depending on the

9547 type of file_info_ptr parameter.
9548 If mapped location support is enabled, create the isomorphic mapping
9549 between source files and line maps.
9550 (Sloc_to_locus): If mapped location support is enabled, translate
9551 source location into mapped location.

9579 Add a section on leap seconds control along with two entities used to
9580 enable and disable leap seconds support. The array Leap_Second_Times is
9581 now constant and contains hard time values pre-generated. Remove
9582 all elaboration code used to populate the table of leap seconds.
9585 Add entity Leap_Seconds_Support to the list of global run-time variables
9586 along with a comment on its usage and values.

9643 Eric Botcazou <ebotcazou@adacore.com>
9646 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9647 indirection added to the HT_Link component of the TSD. This is required
9648 to statically allocate the TSD.
9651 Minor reordering of the declarations in the private part. Required to
9652 add a level of indirection to the contents of the TSD component HT_Link.
9653 This is required to statically allocate the TSD.
9655 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9656 Is_Statically_Allocated set from constant objects.
9657 Do not make exported constants created by the compiler volatile.
9658 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9661 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9662 before returning them.
9664 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9665 public part of the package.
9666 (Make_DT): Move HT_Link component out of the TSD record. For this
9667 purpose Make_DT now declares a separate object that stores the
9668 HT_Link value, and initializes the TSD component with the address
9669 of this new object. The addition of this level of indirection is
9670 required to statically allocate the TSD because the TSD cannot
9671 have variable components.
9672 (Expand_Interface_Conversion): Improve the expanded code.
9673 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9675 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9676 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9677 if we are building static dispatch tables then we must not generate
9678 extra code to register the primitive because the dispatch table will
9679 be built at the end of the library package; otherwise we notify that
9680 we cannot build the static dispatch table.
9682 2007-09-26 Robert Dewar <dewar@adacore.com>
9684 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9699 for thunks associated with interface types.
9701 * einfo.ads: Improve documentatation of Is_Internal
9702 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9703 associated with interface types.
9704 Extensive comment fixes regarding flags that appear in all entities. The
9705 documentation is now consistent for all such flags (there were a number
9706 of errors in the documentation in this regard).
9708 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9710 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9711 of these procedures are passed a function call that already has
9712 build-in-place actuals (testing new flag
9713 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9714 the case where processing continues.
9715 (Expand_Call): If the call is generated from a thunk body then we
9716 propagate the extra actuals associated with the accessibility
9717 level of the access type actuals.
9719 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9720 of each extra formal of a protected operation to reference the
9721 corresponding extra formal of the subprogram denoted by the
9722 operation's Protected_Body_Subprogram.
9724 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9725 N_Function_Call nodes.
9727 2007-09-26 Robert Dewar <dewar@adacore.com>
9729 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9731 * debug.adb: Add d.s flag.
9733 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9735 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9736 debug variable so that it won't be initialized when pragma
9737 Initialize_Scalars is in effect.
9739 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9741 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9742 initialization of a full view. This is moved to
9743 Analyze_Package_Specification.
9745 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9746 preelaborable initialization of a full view in entity loop.
9747 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9748 its child units are use-visible only if they are visible child units.
9750 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9751 whether an expression can be used within a type declaration that
9752 requires preelaborable init.
9753 (Check_Components): Replace inline code that does partial checking for
9754 preelaborable default expressions with call to
9755 Is_Preelaborable_Expression.
9756 (Has_Preelaborable_Initialization): In the case of a generic actual
9757 subtype, (that is, Is_Generic_Actual is True), return the result of
9758 applying Has_Preelaborable_Initialization to the generic actual's base
9761 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9763 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9764 call to Jan_1_Day _Of_Week to optimize its performance.
9765 (Is_Leap): Move the routine to the scope of Week_In_Year.
9766 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9767 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9768 avoids calling Time_Of and Split, thus making it more efficent.
9769 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9771 * g-calend.ads (Week_In_Year): Change comment to reflect new
9774 2007-09-26 Emmanuel Briot <briot@adacore.com>
9776 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9777 Command_Line): New types
9778 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9779 support for defining how switches can be grouped on a command line (as
9780 is the case for -gnatw... for GNAT), and how simple switches can be
9781 used as aliases for more complex switches (-gnatwa is same as
9783 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9784 (Start, Current_*): New subprograms
9785 Added support for parsing an array of strings in addition to the real
9787 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9788 be moved from the body to the private part of the spec.
9789 (*): All subprograms now have an extra parameter with default value to
9790 specify which parser should be used. For backward compatibility, it
9791 defaults to parsing the command line of the application. They were also
9792 modified to properly handle cases where each of the argument does not
9793 start at index 1 (which is always true for Ada.Command_Line, but not
9794 when processing any Argument_List).
9795 (Free): New subprogram
9796 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9797 Argument): New subprograms
9798 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9799 special characters like ':', '=',... are now handled in a single place,
9800 which makes the code more extensible eventually.
9801 (Getopt, Full_Switch): When the switch was returned as part of the
9802 special character '*', make sure it is prepended by the switch character
9803 ('-' in general), so that the application knows whether "foo" or "-foo"
9804 was specified on the command line.
9806 2007-09-26 Florian Villoing <villoing@adacore.com>
9808 * g-dirope.adb (Remove_Dir): In case we are removing directories
9809 recursively, make sure that if an exception is raised during the
9810 processing, the current working directory is reset to its initial
9811 value before propagating the exception.
9813 2007-09-26 Vincent Celier <celier@adacore.com>
9815 * gnatbind.adb: If there are several ALI files specified and there is
9816 a main program to bind, the first ALI is expected to contain the main
9817 subprogram and the names of the binder generated files will be derived
9818 from the first ALI file name.
9819 (Gnatbind): Fix insertion character in invocation of Error_Msg
9821 2007-09-26 Vincent Celier <celier@adacore.com>
9823 * gnatcmd.adb (Check_Files): Do not include sources that have been
9824 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9826 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9828 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9829 information about each of its index types, following the type
9830 reference for its component type.
9832 2007-09-26 Vincent Celier <celier@adacore.com>
9834 * make.adb: (Kill): New procedure (__gnat_kill imported)

9845 2007-09-26 Vincent Celier <celier@adacore.com>
9847 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9849 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9850 Replace components Compiler_Min_Options and Binder_Min_Options with
9851 Compiler_Required_Switches and Binder_Required_Switches in record
9853 Remove components Default_Language and Config in Project_Tree_Data,
9856 * prj-attr.adb: New attributes Required_Switches (<language>) in
9857 packages Compiler and Binder.
9859 * prj-nmsc.adb: Major rewrite of the processing of configuration
9860 attributes for gprbuild. No impact on GNAT tools.
9862 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer

9868 (Process): Implementation now uses the two new procedures
9870 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9871 from the project config, not the tree config that no longer exists.

9894 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9896 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
9897 ancestor of the derived type, the operations are inherited from the
9898 primary dispatch table of the parent.
9899 (OK_For_Limited_Init_In_05): Remove old comment. Reject in-place calls
9900 when the context is an explicit type conversion.
9902 2007-09-26 Ed Schonberg <schonberg@adacore.com>

10202 potentially be called.
10203 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10204 body for 'Output when the type is abstract (only the creation of the
10205 body for 'Input is excluded when the type is abstract).
10206 (Stream_Operation_OK): Add an additional condition in the return
10207 statement, so that False will be returned for TTS_Stream_Input if the
10208 associated tagged type is an abstract extension. Add comments for
10210 (Expand_N_Object_Declaration): For the case of a shared passive
10211 variable, insert init proc call only after the shared variable
10212 procedures have been processed, because the IP call needs to undergo
10213 shared passive variable reference expansion, which requires these

10226 type, retrieve its value from the aggregate itself, where it must have
10229 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10230 to remove other spurious ambiguities on arithmetic operations involving
10231 literals and addresses, on systems where Address is a visible integer
10232 type, when the operator is called in functional notation.
10233 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10234 is legal when the types match, even if the operation is currently

10364 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10365 exceptions never being raised.
10366 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10382 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10383 library-level package renaming, pass the declaration associated with
10384 the renaming's special debug variable to Qualify_Entity_Names to ensure
10385 that its encoded name is properly qualified.
10387 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10388 occurring in the list of entities to qualify, and do not attempt to
10389 traverse an entity list in that case. Variables associated with
10390 ` library-level package renamings can now occur in the table.

10414 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10415 concatenations of string literals into a single literal, in order to
10416 avoid very deep recursion in the front end, which was causing stack
10419 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10420 string, and the right operand is a string literal (the case of "" &
10421 "..."), optimize by avoiding copying the right operand -- just use the
10422 value of the right operand directly.
10424 * stringt.adb (Store_String_Chars): Optimize by growing the
10425 String_Chars table all at once, rather than appending characters one by
10427 (Write_String_Table_Entry): If the string to be printed is very long,
10428 just print the first few characters, followed by the length. Otherwise,
10429 doing "pn(n)" in the debugger can take an extremely long time.
10431 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10432 Store_String_Char with Store_String_Chars.

10445 * sem_ch10.adb (Analyze_Subunit_Context): When analyzing context
10446 clauses of subunits, ignore limited_with_clauses that are illegal and
10447 have not been fully analyzed.
10449 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10451 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10452 flag, for effiency. It is called when analyzing arithmetic operators
10453 and also for actuals in calls that are universal_integers. The flag is
10454 set for the predefined type address, and for any type or subtype
10457 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10458 Universal_Integer, when the formal is a descendent of address and the
10459 call appears in user code.

10524 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10526 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10527 associated with Standard_Debug_Renaming_Type, to be used as the type of
10528 the special variables whose names provide debugger encodings for
10529 renaming declarations.
10531 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10532 (Set_Debug_Renaming_Link): Change to set Node25.

10541 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10542 and the entity of the renaming declaration.
10543 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10544 part of the name of a variable that has a Debug_Renaming_Link.
10546 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10547 special type to be associated with variables that provide debugger

10551 Ed Schonberg <schonberg@adacore.com>
10552 Javier Miranda <miranda@adacore.com>
10554 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10555 ancestor part given by an aggregate to test for an unchecked conversion,
10556 since this can occur in some cases when the ancestor part is a function
10557 call, and we don't want to fall into the recursive call to this
10558 procedure in that case.
10560 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10561 stream attributes on limited types to account for user-specified
10562 attributes as well as whether Input (resp. Output) becomes available
10563 due to Read (resp. Write) being available for the type. Change Boolean
10564 variable to the more accurate name
10565 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10566 double-"not" predicate at beginning of return statement to more
10567 understandable form.
10569 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10570 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10571 in a block statement and use that as the first statement of the
10572 expanded return rather than incorrectly using the handled sequence as
10573 the first statement.
10575 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10576 operation, generate an explicit freeze node for it rather than
10577 generating extra formals, to ensure that gigi has the proper order of
10578 elaboration for anonymous subtypes in the signature of the subprograms.
10579 (Build_In_Place_Formal): Move assertion to beginning of loop.
10580 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10581 applied to a function call (occurs for some cases of 'Input).

10583 applied to a function call (occurs for some cases of 'Input).
10585 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10586 2005, generate an extended return statement enclosing the result object
10589 * freeze.adb (Freeze_Record_Type): Extend the current management of
10590 components that are access type with an allocator as default value: add
10591 missing support to the use of qualified expressions of the
10592 allocator (which also cause freezing of the designated type!)
10593 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10594 dispatching operation, since extra formals may be needed by calls to
10595 build-in-place functions (such as stream 'Input).
10597 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10598 formals for 'Constrained and accessibility level in the case of a
10599 predefined dispatching operation.
10601 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10602 point, no need to find the parent node.
10604 2007-08-16 Javier Miranda <miranda@adacore.com>
10606 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10607 and entry barriers.
10609 2007-08-16 Javier Miranda <miranda@adacore.com>
10611 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10612 is not really required and can introduce regression with the debugger.
10613 The original problem is fixed with the patch written for checks.adb.
10615 2007-08-16 Thomas Quinot <quinot@adacore.com>
10617 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10623 Including_Non_Switch set to False.
10624 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10625 Including_Non_Switch set to False.
10627 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10628 parameter Including_Non_Switch, defaulted to True. When
10629 Including_Non_Switch is False, options that are not switches and
10630 appear as relative path are not converted to absolute paths.
10632 2007-08-16 Nicolas Roche <roche@adacore.com>
10634 * Makefile.in (gnatlib): Propagate FORCE_DEBUG_ADAFLAGS value to sub

10641 * sem_ch10.adb (Has_With_Clause): If the name of the with clause
10642 currently inspected is a selected component, retrieve the entity of
10644 (Install_Limited_Withed_Unit): Call Has_Limited_With_Clause starting
10645 from the immediate ancestor of Main_Unit_Entity.
10646 (Install_Limited_Withed_Unit): Do not install the limited view of
10647 package P if P is reachable through an ancestor chain from package C
10648 and C also has a with clause for P in its body.
10649 (Has_Limited_With_Clause): New routine.
10650 (Has_With_Clause): New routine.
10652 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10654 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10655 generic for an enclosing instance is a global reference, even though
10656 its scope is the enclosing instance.
10658 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10659 Javier Miranda <miranda@adacore.com>
10661 * sem_ch3.adb (OK_For_Limited_Init_In_05): Allow calls to 'Input to
10662 initialize a limited object.

10667 2007-08-16 Robert Dewar <dewar@adacore.com>
10669 * sem_ch5.adb (Analyze_Assignment): Make sure we still note update in
10672 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10674 * sem_disp.adb (Check_Dispatching_Operation): If the operation
10675 implements an operation inherited from a progenitor interface, verify
10676 that they are subtype-conformant.
10678 2007-08-16 Hristian Kirtchev <kirtchev@adacore.com>
10679 Bob Duff <duff@adacore.com>
10680 Nicolas Setton <setton@adacore.com>
10682 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10683 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10684 the statement which is being resolved comes from a predefined library
10685 unit, all non-predefined library interpretations are skipped.
10686 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10687 but the "&" is user defined, give an error, because the folding would
10690 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
10691 the parser has folded a long sequence of concatenations of string
10694 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10695 and "JMP_BUF" variables as artificial.
10696 (N_String_Literal): Do not use alloca for very long string literals. Use
10697 xmalloc/free instead. Otherwise the stack might overflow.
10699 * utils.c (init_gigi_decls): Mark "JMPBUF_T" type as created by the

10744 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10745 Suppress unmodified in-out parameter warning in some cases
10746 This patch is a also fairly significant change to the way suppressible
10747 checks are handled.
10749 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10750 needed for access to concurrent record types generated by the expander.
10751 (Generate_Range_Check): When generating a temporary to capture the
10752 value of a conversion that requires a range check, set the type of the
10753 temporary before rewriting the node, so that the type is always
10754 properly placed for back-end use.
10755 (Apply_Float_Conversion_Check): Handle case where the conversion is
10757 (Get_Discriminal): Code reformatting. Climb the scope stack looking

10773 (Expand_N_Type_Conversion): Test for the case of renamings of access
10774 parameters when deciding whether to apply a run-time accessibility
10776 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10777 aggregate code before allocator, and ahead of declaration for
10778 temporary, to prevent access before elaboration when the allocator is
10779 an actual for an access parameter.
10780 (Expand_N_Type_Conversion): On an access type conversion involving an
10781 access parameter, do not apply an accessibility check when the
10782 operand's original node was an attribute other than 'Access. We now
10783 create access conversions for the expansion of 'Unchecked_Access and
10784 'Unrestricted_Access in certain cases and clearly accessibility should
10785 not be checked for those.
10787 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10788 includes a type conversion of a packed component that has been expanded,
10789 recover the original expression for the object, and use this expression
10790 in the post-call assignment statement, so that the assignment is made
10791 to the object and not to a back-end temporary.
10792 (Freeze_Subprogram): In case of primitives of tagged types not defined
10793 at the library level force generation of code to register the primitive
10794 in the dispatch table. In addition some code reorganization has been
10795 done to leave the implementation clear.
10796 (Expand_Call): When expanding an inherited implicit conversion,
10797 preserve the type of the inherited function after the intrinsic
10798 operation has been expanded.
10800 * exp_ch2.ads, exp_ch2.adb
10801 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10802 of an entry formal appearing in an assignment statement does not assign
10804 (Expand_Current_Value): Instead of calling a routine to determine
10805 whether the prefix of an attribute reference should be optimized or
10806 not, prevent the optimization of such prefixes all together.
10808 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10809 component whose prefix is known to be of an access type is an implicit
10810 dereference and does not assign to the prefix.
10812 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10813 Robert Dewar <dewar@adacore.com>
10815 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10816 itype is visited, make an entry into table to link associated node and
10818 Add comments and correct harmless error in Build_NCT_Hash_Tables
10819 (Array_Aggr_Subtype): Associate each itype created for an index type to
10820 the corresponding range construct, and not to the aggregate itself. to

10822 node, to prevent errors when complex expression is copied.
10823 Fix mishandling of multiple levels of parens
10825 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10826 treatment of limited views uniform for all visible declarations in a
10827 limited_withed package.
10828 (New_Copy_Tree): If hash table is being used and itype is visited,
10829 make an entry into table to link associated node and new itype.
10830 (Resolve_Record_Aggregate): Do not add an others box association for a
10831 discriminated record component that has only discriminants, when there
10832 is a box association for the component itself.

10881 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10882 generation of a freezing node to ensure proper management of null
10883 excluding access types in the backend.
10884 (Create_Extra_Formals): Test base type of the formal when checking for
10885 the need to add an extra accessibility-level formal. Pass the entity E
10886 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10887 originally being done in a couple of cases), to ensure that the
10888 Extra_Formals list gets set on the entity E when the first entity is
10890 (Conforming_Types): Add missing calls to Base_Type to the code that
10891 handles anonymous access types. This is required to handle the
10892 general case because Process_Formals builds internal subtype entities
10893 to handle null-excluding access types.
10894 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10895 functions that need it, even when not marked Requires_Overriding.
10896 Improve warnings for in out parameters
10897 (Analyze_Function_Return): Warn for disallowed null return
10898 Warn on return from procedure with unset out parameter
10899 Ensure consistent use of # in error messages
10900 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10901 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10902 the implicit conversion of the expression done for anonymous access
10903 types. This is required to generate the code of the null excluding
10904 check (if required).
10906 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10907 A formal parameter is never publicly referenceable outside of its body.
10908 (Check_References): For an unreferenced formal parameter in an accept
10909 statement, use the same warning circuitry as for subprogram formal
10911 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10912 Output_Unreferenced_Messages, containing the part of that routine that
10913 is now reused for entry formals as described above.

10915 (Check_References): Do not give IN OUT warning for dispatching operation
10916 Improve warnings for in out parameters

10923 Javier Miranda <miranda@adacore.com>
10924 Gary Dismukes <dismukes@adacore.com>
10926 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10927 (Expand_N_Attribute_Reference): Further unify the handling of the
10928 three forms of access attributes, using common code now for all three
10929 cases. Add a test for the case of applying an access attribute to
10930 an explicit dereference when the context is an access-to-interface
10931 type. In that case we need to apply the conversion to the prefix
10932 of the explicit dereference rather than the prefix of the attribute.
10933 (Attribute_Version, UET_Address): Set entity as internal to ensure
10934 proper dg output of implicit importation.
10935 (Expand_Access_To_Type): Removed.
10936 (Expand_N_Attribute_Reference): Merge the code from the three cases
10937 of access attributes, since the processing is largely identical for
10938 these cases. The substantive fix here is to process the case of a
10939 type name prefix (current instance case) before handling the case
10940 of interface prefixes.

10945 Robert Dewar <dewar@adacore.com>
10947 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10948 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10949 type that is an anonymous access to controlled object, establish
10950 an associated finalization chain to avoid corrupting the global
10951 finalization list when a dynamically allocated object designated
10952 by such a component is deallocated.
10953 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10954 functions that need it, even when not marked Requires_Overriding.
10955 (Initialize_Tag): Replace call to has_discriminants by call to
10956 Is_Variable_Size_Record in the circuitry that handles the
10957 initialization of secondary tags.
10958 (Is_Variable_Size_Record): New implementation.
10959 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10960 Suppress_Initialization pragma for a derived type.
10961 (Is_Variable_Size_Record): New subprogram.
10962 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10963 initial version of this routine and also fixes problems causing
10964 incomplete initialization of the table of interfaces.
10965 (Build_Init_Procedure): Improve the generation of code to initialize the
10966 the tag components of secondary dispatch tables.
10967 (Init_Secondary_Tags): New implementation that simplifies the previous
10968 version of this routine.
10969 (Make_DT): Add parameter to indicate when type has been frozen by an
10970 object declaration, for diagnostic purposes.
10971 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10972 diagnose attemps to freeze a subprogram when some untagged type of its
10973 profile is a private type whose full view has not been analyzed yet.
10974 (Freeze_Array_Type): Generate init proc for packed array if either
10975 Initialize or Normalize_Scalars is set.
10976 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10977 constructing the new profile, copy the null_exclusion indicator for each
10978 parameter, to ensure full conformance of the new body with the spec.
10980 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10981 Create wrappers for constructor functions that need it, even when not
10982 marked Requires_Overriding.
10983 (Covers): Handle properly designated types of anonymous access types,
10984 whose non-limited views are themselves incomplete types.
10985 (Add_Entry): Use an entity to store the abstract operation which hides
10987 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.

10992 (Has_Compatible_Type): Remove machinery that skips interpretations if
10993 they are labeled as potentially hidden by an abstract operator.
10994 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10995 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10996 (Write_Overloads): Output the abstract operator if present.
10997 (Add_Entry): Before inserting a new entry into the interpretation table
10998 for a node, determine whether the entry will be disabled by an abstract

11015 types declared in the declarative part of a nested package body or in
11016 the proper body of a stub.
11017 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11018 of the same dispatch table slot to renamed primitives.
11019 (Make_Select_Specific_Data_Table): Handle private types.
11020 (Tagged_Kind): Handle private types.
11021 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11022 output of implicit importation and exportation.
11023 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11024 first formal of the thunk is always associated with the controlling
11025 type. In addition perform the following code cleanup: remove formal
11026 Thunk_Alias which is no longer required, cleanup evaluation of the
11027 the controlling type, and update the documentation.
11028 Replace occurrence of Default_Prim_Op_Count by
11029 Max_Predef_Prims. Addition of compile-time check to verify
11030 that the value of Max_Predef_Prims is correct.
11031 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11032 (Make_DT): Add parameter to indicate when type has been frozen by an
11033 object declaration, for diagnostic purposes.
11034 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11035 construction of statically allocated dispatch tables.
11036 (Make_DT): In case of library-level tagged types export the declaration
11037 of the primary tag. Remove generation of tags (now done by Make_Tags).
11038 Additional modifications to handle non-static generation of dispatch
11039 tables. Take care of building tables for asynchronous interface types
11040 (Make_Tags): New subprogram that generates the entities associated with
11041 the primary and secondary tags of Typ and fills the contents of Access_
11042 Disp_Table. In case of library-level tagged types imports the forward
11043 declaration of the primary tag that will be declared later by Make_DT.
11044 (Expand_Interface_Conversion): In case of access types to interfaces
11045 replace an itype declaration by an explicit type declaration to avoid
11046 problems associated with the scope of such itype in transient blocks.

11049 Ed Schonberg <schonberg@adacore.com>
11050 Javier Miranda <miranda@adacore.com>
11052 * exp_util.ads, exp_util.adb:
11053 This patch replaces a number of occurrences of explicit tests for N_Null
11054 with calls to Known_Null. This improves tracking of null values, since
11055 Known_Null also catches null constants, and variables currently known to
11056 be null, so we get better tracking.
11057 (Ensure_Defined): create an itype reference only in the scope of the
11059 (Side_Effect_Free): A selected component of an access type that
11060 denotes a component with a rep clause must be treated as not
11061 side-effect free, because if it is part of a linked structure its
11062 value may be affected by a renaming.
11063 (Expand_Subtype_From_Expr): For limited objects initialized with build
11064 in place function calls, do nothing; otherwise we prematurely introduce
11065 an N_Reference node in the expression initializing the object, which
11066 breaks the circuitry that detects and adds the additional arguments to
11067 the called function. Bug found working in the new patch for statically
11068 allocated dispatch tables.
11069 (Is_Library_Level_Tagged_Type): New subprogram.
11070 (Remove_Side_Effects): If the expression of an elementary type is an
11071 operator treat as a function call.
11072 (Make_Literal_Range): If the index type of the array is not integer, use
11073 attributes properly to compute the constraint on the resulting aggregate
11076 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11077 class-wide type whose base type is an incomplete private type, leave
11078 class-wide type unfrozen so that freeze nodes can be generated
11079 properly at a later point.
11080 (Freeze_Entity, array case): Handle case of pragma Pack and component
11081 size attributre clause for same array.

11141 source dirs are not known.
11142 (Check_Ada_Name): Allow all identifiers that are not reserved words

11736 takes progenitor types into account.
11737 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11738 traversing over the primitives of the formal and actual types to locate
11739 any abstract subprograms of the actual type that correspond to a
11740 nonabstract subprogram of the formal type's ancestor type(s), and issue
11741 an error if such is found.

11757 an access_to_constant type.
11758 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11759 type, the candidate operations are found in the scope of declaration of
11760 the type, because the type has no primitive subprograms.
11761 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11762 a private extension, only examine visible components before trying to
11763 analyze as a prefixed call.

11778 purpose of enforcing E.2.2(8) only if it is not available at any place.
11779 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11780 when checking the legality of an extension aggregate in a preelaborable
11781 package. Treat the literal null as a valid default expression in a
11782 component declaration for a type with preelaborable initialization.
11783 A limited interface is a legal progenitor for the designated type of a
11784 remote access to class-wide type.

11821 whose type depends on discriminants, build its actual subtype before
11822 applying range checks on the bounds of the slice.

11824 to prevent anomalies between private and public views.

11846 elabration statements, register the package with the name server
11847 at the beginning, not at the end, of the elaboration statements so

13016 components of records. Set to point to the entity of the corresponding
13018 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13019 (Original_Access_Type): Remove, not needed.
13020 (Root_Type): Handle properly subtypes of class-wide-types.
13023 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13024 class-wide types visible through limited-with clauses.
13025 (Try_Primitive_Operation): When examining all primitive operations of a
13026 tagged type, do not consider subprograms labeled as hidden unless they
13027 belong to a private generic type with a tagged parent.
13028 (Try_Object_Operation): Extensive rewriting, to handle properly various
13029 overloading cases, when several ancestors may have class-wide operations
13030 that are possible candidates, and when the overloaded functions return
13031 array types and have defaulted parameters so that the call may be
13032 interpreted as an indexing.
13033 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13034 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13035 successive actuals before analyzing the call itself.
13036 (Try_Primitive_Operation): A primitive operation is compatible with the
13037 prefix if the prefix has a synchronized type and the type of the formal
13038 is its corresponding record, as can be the case when the primitive
13039 operation is declared outside of the body of the type.
13040 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13041 perform homonym traversal, looking for class-wide operation matches
13042 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13043 access parameters are now restricted to anonymous access types.
13044 (Mark_Allocator): An allocator with a discriminant association parent is
13046 (Try_One_Prefix_Interpretation): If the type of the object is
13047 incomplete, as can be happen when it is a limited view obtained through
13048 a limited_with_clause, the selected component is not part of a prefixed
13050 (Complete_Object_Operation): Diagnose properly an object that is not
13051 aliased when the corresponding controlling formal is an access
13053 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13054 ambiguous calls in prefixed notation, where two primitives differ only
13055 in that the controlling argument of one is an access parameter.
13057 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13058 whether a function that returns an unconstrained type can be inlined.
13059 (Process_Formals): Diagnose properly the illegal use of an incomplete
13060 type in the profile of an access_to_subprogram declaration.
13061 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13062 operations are attached to the corresponding record.
13063 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13064 When processing a primitive of a concurrent type which implements an
13065 interface change the type of all controlling formals to that of the
13066 corresponding record type.
13067 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13068 to determine the tagged type to which a primitive belongs.
13069 (Check_Conventions): Capture condition to ignore a primitive operation
13070 (which is shared between the loop in Check_Conventions and the one in
13071 Check_Convention) in a new local function Skip_Check.
13072 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13073 confusion with Check_Conventions' own Prim_Op local variable.
13074 (Create_Extra_Formals): Test for a tagged result type rather than a
13075 controlling result when determining whether to add a BIP_Alloc_Form
13076 formal and a BIP_Final_List formal to the function.
13077 (Check_Conformance); For parameters that are anonymous access types,
13078 subtype conformance requires that the not null and the constant
13079 indicators must match
13080 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13081 to retrieve the appropriate type when processing a concurrent type
13082 declared within a generic. Minor comment reformatting. Change invocation
13083 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13085 (Analyze_Subprogram_Body): If the return type of a function is an
13086 anonymous access to the limited view of a class-wide type, and the
13087 non-limited view of the type is available, update the type of the
13088 function so that code can be generated.
13089 (Process_Formals): In case of access-subtype itype whose designated
13090 type is also an itype (situation that happens now with access to
13091 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13092 attribute to avoid backend problems.
13093 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13094 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13095 anonymous types' designated types are same before testing
13096 Subtypes_Statically_Match.
13097 (Create_Extra_Formals): Test for a named access parameter that is a
13098 controlling formal as an additional condition for adding an
13099 accessibility level formal. This can occur in the subp type created for
13100 dispatching calls in Expand_Dispatching_Call, and allows calling
13101 Create_Extra_Formals from that procedure rather than special-casing the
13102 extra formals there.
13103 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13104 when the function has a controlling result.
13105 (Check_Returns): Add much more knowledge of the optimization of local
13106 raise statements to gotos, to retain proper warnings in this case.
13107 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13108 nodes when looking for last statement.
13110 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13111 class-wide types visible through limited with clauses.
13112 (Add_One_Interp): If the operands are anonymous access types, the
13113 predefined operator on universal_access is immediately visibles
13114 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13115 other anonymous access types.
13116 (Disambiguate): Take into account CIL convention.
13117 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13119 2007-06-06 Robert Dewar <dewar@adacore.com>
13121 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13122 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13123 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13124 Fix lower bound of tables.
13127 * nlists.adb: Ditto.
13128 (Prev_Node, Next_Node): Change index type to Int so that it properly
13129 covers the range First_Node_Id - 1 up.
13131 2007-06-06 Javier Miranda <miranda@adacore.com>
13132 Ed Schonberg <schonberg@adacore.com>
13133 Bob Duff <duff@adacore.com>
13134 Hristian Kirtchev <kirtchev@adacore.com>
13136 * exp_aggr.ads, exp_aggr.adb:
13137 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13138 in extension aggregates.
13139 (Flatten): Other conditions being met, an aggregate is static if the
13140 low bound given by component associations is different from the low
13141 bound of the base index type.
13142 (Packed_Array_Aggregate_Handled): If the component type is itself a
13143 packed array or record, the front-end must expand into assignments.
13144 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13145 Init_Pr, instead of Ancestor_Is_Expression.
13146 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13147 coextension chain root, either generate a list controller or use the
13148 already existing one.
13149 (Static_Array_Aggregate): New procedure to construct a positional
13150 aggregate that can be handled by the backend, when all bounds and
13151 components are compile-time known constants.
13152 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13153 types covering interface types into assignments.
13154 (Replace_Type): move to Build_Record_Aggr_Code.
13155 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13156 interface type, convert to the definite type of the aggregate itself,
13157 so that needed components are visible.
13158 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13159 components and the context is an extended return statement do not
13160 create a transient block for it, to prevent premature finalization
13161 before the return is executed.
13162 (Gen_Assign): Do not generate a call to deep adjust routine if the
13163 component type is itself an array of controlled (sub)-components
13164 initialized with an inner aggregate.
13165 (Component_Check): New name for Static_Check. This name is now more
13166 appropriate, and documentation is added which was missing.
13167 (Component_Check): Add test for bit aligned component value
13168 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13169 Tagged_Comps, name is more appropriate given added function below.
13170 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13172 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13173 Javier Miranda <miranda@adacore.com>
13174 Robert Dewar <dewar@adacore.com>
13176 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13177 Terminated: Add unchecked type conversion from System.Address to
13178 System.Tasking.Task_Id when calling the predefined primitive
13180 Disable new Ada 05 accessibility check for JVM.NET targets, which
13181 cannot be implemented in a practical way.
13182 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13183 the sources always references the tag of the actual object. Therefore,
13184 if 'Tag is applied in the sources to class-wide interface objects we
13185 generate code that displaces "this" to reference the base of the object.
13186 (Expand_N_Attribute_Reference, case Size): Return specified size if
13187 known to front end.
13188 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13189 has code that displaces the pointer of the object to manage interface
13190 types. However this code must not be executed when the prefix is a
13191 subprogram. This bug caused the wrong expansion of the internally
13192 generated assignment that fills the dispatch table when the primitive
13193 is a function returning a class-wide interface type.
13194 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13195 Set_Attribute_Name for Name_Unaligned_Valid.
13197 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13198 Gary Dismukes <dismukes@adacore.com>
13200 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13201 If the initialization is the equivalent aggregate of the initialization
13202 procedure of the type, do not remove it.
13203 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13204 initialized to null from having their expression reset to empty and
13205 note this exception in the comment.

13209 Ed Schonberg <schonberg@adacore.com>
13210 Gary Dismukes <dismukes@adacore.com>
13212 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13213 Add "with" and "use" clauses for Sem_Attr.
13214 (Expand_Current_Value): Do not replace occurences of attribute
13215 references where the prefix must be a simple name.
13217 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13218 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13219 Attribute_Requires_Simple_Name_Prefix.
13220 (Name_Modifies_Prefix): Body of new function.
13221 (Requires_Simple_Name_Prefix): Body of new function.
13222 (Resolve_Attribute, case Access): Improve error message for case of
13223 mismatched conventions.
13224 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13226 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13227 constrained subtype for a nominal unconstrained type, use its base type
13228 to check for conformance with the context.
13229 (Resolve_Attribute): Remove test of the access type being associated
13230 with a return statement from condition for performing accessibility
13231 checks on access attributes, since this case is now captured by
13232 Is_Local_Anonymous_Access.
13233 (Analyze_Access_Attribute): Set Address_Taken on entity
13234 (Analyze_Attribute, case Address): Set Address_Taken on entity
13235 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13236 validating an access attribute whose prefix is a current instance.
13237 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13238 applied to dispatching operations, if freezing is required then we set
13239 the attribute Has_Delayed_Freeze in the prefix's entity.
13240 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13241 current scope if access of local subprogram taken
13242 (Analyze_Access_Attribute): Check legality of self-reference even if the
13243 expression comes from source, as when a single component association in
13244 an aggregate has a box association.
13245 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13246 the prefix if it is a protected operation and the attribute is
13247 Unrestricted_Access.
13248 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13249 reference to the base type of the context, to force a constraint check
13250 when the context is an access subtype with an explicit constraint.
13251 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13252 node is rewritten as an interface conversion. leave unanalyzed after
13253 resolution, to ensure that type checking against the context will take

13257 Javier Miranda <miranda@adacore.com>
13258 Robert Dewar <dewar@adacore.com>
13260 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13261 wrapper when the full view of the controlling type of an inherited
13262 function that dispatches on result implements interfaces.
13263 (Expand_N_Object_Declaration): In cases where the type of the
13264 declaration is anonymous access, create finalization list for it.
13265 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13266 if the object has no explicit initialization, to match description of
13267 functionality of pragam Persistent_BSS.
13268 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13269 new function to build static aggregates, to replace initialization call
13270 when static initialization is desired.
13271 (Freeze_Type): Generate a list controller for an access type whenever
13272 its designated type has controlled anonymous access discriminants.
13273 (Build_Equivalent_Aggregate): New procedure to compute a static
13274 aggregate to be used as default initialization for composite types,
13275 instead of a generating a call to the initialization procedure for the
13277 (Build_Initialization_Call): When available, replace a call to the
13278 initialization procedure with a copy of the equivalent static aggregate
13280 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13281 declarations for objects of a class-wide interface type, rather than
13282 just identifiers, to prevent visibility problems.
13283 (Expand_N_Object_Declaration): When expanding the declaration for an
13284 object of a class-wide interface type, preserve the homonym chain of
13285 the original entity before exchanging it with that of the generated
13286 renaming declaration.
13287 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13288 active, because there is no way to handle the exception.
13289 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13290 to do a minimum decoration of the Access_Disp_Table list.
13291 (Expand_Record_Controller): Avoid the addition of the controller between
13292 the component containing the tag of a secondary dispatch table and its
13293 adjacent component that stores the offset to the base of the object.
13294 This latter component is only generated when the parent type has
13295 discriminants ---documented in Add_Interface_Tag_Components).
13296 (Apply_Array_Size_Check): Removed, no longer needed.
13297 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13298 components, create a Master_Entity for it only if it contains tasks.
13299 (Build_Init_Procedure): Suppress the tag assignment compiling under
13301 (Freeze_Record_Type): Remove code associated with creation of dispatch
13303 (Init_Secondary_Tags): Update type of actuals when generating calls to
13304 Ada.Tags.Set_Offset_To_Top
13305 (Stream_Operation_OK): Disable use of streams compiling under no
13307 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13308 if Has_Init_Expression set.
13309 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13310 Register_Primitive, which provides the same functionality.
13311 (Requires_Init_Proc): Return false in case of interface types.
13312 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13314 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13315 is always associated with a predefined primitive because the internal
13316 entities associated with interface types are not predefined primitives.
13317 Therefore, the call to Is_Internal is replaced by a call to the
13318 function Is_Predefined_Dispatching_Operation.
13319 (Make_Eq_If): When generating the list of comparisons for the
13320 components of a given variant, omit the controller component that is
13321 present if the variant has controlled components.
13323 2007-06-06 Javier Miranda <miranda@adacore.com>
13324 Hristian Kirtchev <kirtchev@adacore.com>
13325 Bob Duff <duff@adacore.com>
13327 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13328 handle the creation of finalization lists and calls for nested
13329 coextensions when the root of the chains is part of a return statement.
13330 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13332 (Expand_Record_Equality): Skip components that are interface types.
13333 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13334 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13335 with Rewrite_Coextension. Change the condition for detecting coextension
13337 (Is_Local_Access_Discriminant): Removed.
13338 (Rewrite_Coextension): New routine which rewrites a static coextension
13339 as a temporary and uses its unrestricted access in the construction of
13341 (Complete_Coextension_Finalization): New routine. Generate finalization
13342 attachment calls to all delayed coextensions.
13343 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13344 the allocator is not a coextension itself and has delayed coextensions.
13345 If the current allocator is controlled, but also a coextension, delay
13346 the generation of the finalization attachment call.
13347 Rename local variable "Node" to "Nod" in order to avoid confusion with
13349 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13350 limited types that are not inherently limited. Such an allocator is
13351 illegal, but is generated by the expander for a return statement, to
13352 copy the result onto the secondary stack. This is the only case where a
13353 limited object can be copied. Generate code to displace the pointer
13354 to the object if the qualified expression is a class-wide interface
13355 object. Such displacement was missing and hence the copy of the object
13357 (Apply_Accessibility_Check): Handle allocated objects initialized in
13359 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13360 and Expand_Allocator_Expression. Allocating class-wide interface objects
13361 this routine displaces the pointer to the allocated object to reference
13362 the component referencing the corresponding secondary dispatch table.
13363 Expand_Allocator_Expression): Add missing support to allocate class-wide
13364 interface objects initialized with a qualified expression.
13365 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13366 function result type, and use the finalization list associated with the
13367 function scope in that case (such an anonymous type should not be
13368 treated like an access parameter's type).
13370 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13371 Gary Dismukes <dismukes@adacore.com>
13372 Javier Miranda <miranda@adacore.com>
13374 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13375 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13376 required exception handler.
13377 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13378 properly the case of a function whose return type is a limited
13379 class-wide interface type. Modify the code of the accessibility
13380 check to handle class-wide interface objects. In this case we need to
13381 displace "this" to reference the primary dispatch table to get access
13382 to the TSD of the object (to evaluate its accessibility level).
13383 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13384 rather than a controlling result as one of the conditions for
13385 generating tests of the implicit BIP_Alloc_Form formal. The
13386 initialization assignment is also handled according to whether the
13387 result is tagged instead of controlling.
13388 In the case where the init assignment is inserted in the "then" part of
13389 the allocation conditional, rewrite the target to be a dereference of
13390 the implicit BIP_Object_Access formal.
13391 If the returned value is unconstrained and created on the secondary
13392 stack, mark the enclosing block and function so that the secondary
13393 stack is not reclaimed on return.
13394 Treat returns from functions with controlling results similarly to
13395 returns from functions with unconstrained result subtypes.
13396 If the object returned is unconstrained, and an allocator must be
13397 created for it, analyze the allocator once the block for the extended
13398 return is installed, to ensure that finalizable components
13399 of the expression use the proper finalization list. Guard the call to
13400 Move_Final_List with a check that there is something to finalize.
13401 (Make_Tag_Ctrl_Assignment): Use "old" handling
13402 of controlled type assignment for virtual machines, since new code uses
13403 unsupported features (such as direct access to bytes in memory).
13405 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13406 Ed Schonberg <schonberg@adacore.com>
13408 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13409 accessibility actual, check for the case of an aliased object that has
13410 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13411 we fall into processing for the attribute rather than the name of the
13413 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13414 formal has its address taken in the body, create a temporary to capture
13415 value. If the return type is a limited interface, do not treat the
13416 return value as Controlled.
13417 (Is_In_Place_Function): If the return type is a limited interface,
13418 treat as returning in place. The actual returned object may not always
13419 be limited, but the caller has to assume that it is returned in place.
13420 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13421 context of an allocator, use the correct finalization chain (that is,
13422 the chain belonging to the access type, rather than the chain belonging
13423 to the current scope).
13424 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13425 result type rather than a controlling result as a precondition for
13426 adding an allocation form actual to a build-in-place call.
13427 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13428 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13429 primitive in the dispatch tables. This work is now done by Make_DT when
13430 the type is frozen.
13431 (Register_Predefined_DT_Entry): Removed.
13432 (Add_Return): If end label is not present, use sloc of last statement
13433 for generated return statement in procedure, for better gdb behavior
13435 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13436 object address nodes to ensure proper processing by routines like
13438 (Expand_Call): Fix generation of validity check for parameter
13439 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13440 the allocation form parameter if the result subtype is constrained,
13441 except when the function has a controlling result.
13442 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13443 rather than Is_Controlled and Has_Controlled_Component, since we want to
13444 include class-wide result types in this treatment. Also test for a
13445 controlling result, since that also requires passing a finalization
13447 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13448 even when the result subtype is constrained, to handle calls involving
13449 controlling results.
13450 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13451 is now called even when the result subtype is constrained, to handle
13452 calls involving controlling results.
13453 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13454 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13455 now performs the test).
13456 (Make_Build_In_Place_Call_In_Object_Declaration):
13457 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13458 constrained, to handle calls involving controlling results.
13459 (Add_Return): Accomodate rewritten pattern from local raise to goto
13460 transformation, so that we still recognize an transfer statement
13461 and do the right thing here in that case.
13462 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13463 and end of subprogram code.
13464 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13465 support for primitives that are functions (without formals) with a
13466 controlling result.
13467 (Inherited_From_Formal): If the actual subtype has not generic parent
13468 type, it is not an actual for a formal derived type, and there is no
13469 operation to inherit from the formal.

13478 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13479 Raise_From_Controlled_Operation is available, use a call to that
13480 subprogram instead of a plain "raise Program_Error" node to raise
13481 Program_Error if an exception is propagated from an Adjust or Finalize
13483 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13484 appears in the optional statement list of a triggering alternative, the
13485 scope actions can be inserted directly there, and not in the list that
13486 includes the asynchronous select itself.
13488 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13489 Robert Dewar <dewar@adacore.com>

13516 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13517 functionality when the backend is generating code.
13518 Otherwise any serious error
13519 reported by the backend calling the frontend routine Error_Msg
13520 changes the Compilation_Mode to Check_Semantics, disables the
13521 functionality of this routine and causes the generation of
13522 spureous additional errors.
13524 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13525 debugging information now generated by the compiler for fat-pointer
13527 Document the contents of DW_AT_producer in the GNAT Vendor extensions to

13539 stream attributes of the designated type of an RACW, as they are not
13540 dispatching primitive operations.

13561 deallocation of class-wide interface objects.
13562 (Expand_Dispatching_Constructor_Call): Take into account that if the
13563 result of the dispatching constructor is an interface type, the
13564 function returns a class-wide interface type; otherwise the returned
13565 object would be actual. The frontend previously accepted returning
13566 interface types because Expand_Interface_Actuals silently performed
13567 the management of the returned type "as if" it were a class-wide
13569 (Expand_Dispatching_Constructor_Call): Replace call to
13570 Make_DT_Access_Action by direct call to Make_Function_Call.

13593 renaming, either an attribute renaming or a renaming as body.
13594 (Check_Itype): If the designated type of an anonymous access component
13595 is a non-protected subprogram type, indicate that it is frozen, to
13596 prevent out-of-scope freeze node at some subsequent call.
13597 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13598 only if the subprogram is neither imported nor exported, as well as the

13603 Robert Dewar <dewar@adacore.com>
13604 Gary Dismukes <dismukes@adacore.com>
13606 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a

13632 considererd limited.
13633 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13634 should be declared as limited and that it will be considererd limited.

13659 object of a limited type can be initialized with a call to a function
13660 that returns in place. If the limited type has unknown discriminants,
13661 and the underlying type is a constrained composite type, build an actual
13662 subtype from the function call, as is done for private types.
13663 (Side_Effect_Free): An expression that is the renaming of an object or
13664 whose prefix is the renaming of a object, is not side-effect free
13665 because it may be assigned through the renaming and its value must be
13666 captured in a temporary.
13667 (Has_Controlled_Coextensions): New routine.
13668 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13669 as is done for other limited types.

13726 * opt.ads: Add new warning for renaming of function return objects
13727 (Generating_Code): New boolean variable used to indicate that the

13741 Standard can be renamed.
13742 (Analyze_Object_Renaming): Add new warning for renaming of function
13744 Also reject attempt to rename function return object in Ada 83 mode.
13745 (Attribute_Renaming): In case of tagged types, add the body of the
13746 generated function to the freezing actions of the type.
13747 (Find_Type): A protected type is visible right after the reserved word
13748 "is" is encountered in its type declaration. Set the entity and type

13776 (Deallocate, Dereference): Send error messages to the proper stream
13777 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
13778 documented. Previous code would send it to the current output file
13779 defined in GNAT.IO, which might not be stdout
13780 (Is_Valid): Adjust comment to mention that a positive reply means that
13781 Header_Of may be used to retrieve the allocation header associated with

13801 Correct error message when invocation of the linker fails
13802 Add explicit size clause for the C imported variables
13803 Object_List_File_Supported and Using_GNU_Linker to emphasize that
13804 we expect char size.
13805 Read target parameters earlier, since this is needed to set
13806 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13809 2007-06-06 Vincent Celier <celier@adacore.com>
13812 Add 3 spaces before the default project directory when displaying
13813 the project search path.

15291 (Resolve_Call): If the call returns an array, the context imposes the
15292 component type of the array, and the function has one non-defaulted
15293 parameter, rewrite the call as the indexing of a call with a single
15294 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15296 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15297 the master of the created object is the innermost enclosing statement.
15298 (Remove_Conversions): For a binary operator, check if type of second
15299 formal is numeric, to check if an abstract interpretation is present
15300 in the case of exponentiation as well.

15541 attempt to derive from a synchronized tagged type.

15546 that use (a subtype of) the class-wide type of the enclosing type.
15547 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15548 Derived_Type for Prev formal on call to
15549 Check_Anonymous_Access_Components rather than Empty.
15550 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15551 a record extension in deciding whether to create a class-wide type,

15632 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15633 when -gnatg is not specified.

15687 under No_Dispatching_Calls restriction. During the semantic analysis
15688 we already notified such violation.
15689 (Tagged_Membership): Constant folding. There is no need to check
15690 the tag at run-time if the type of the right operand is non
15691 class-wide abstract.
15692 Replace call to Is_Ancestor by call to Is_Parent
15693 to support concurrent types with interface types.
15694 (Expand_N_Allocator): Add an assertion associated with the generation
15696 (Expand_N_Slice): Do not enable range check to nodes associated
15697 with the frontend expansion of the dispatch table.

15705 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15706 initialize most the TSD components by means of an aggregate.
15707 Modify the declaration of the object containing the TSD
15708 because we now expand code that has a higher level of abstraction.
15709 The TSD has a discriminant containing the Inheritance Depth Level,
15710 value that is used in the membership test but also to fix the size
15711 of the table of ancestors.
15712 (Expand_Interface_Conversion): Insert function body at the closest place
15713 to the conversion expression, to prevent access-before-elaboration
15714 errors in the backend.
15715 Code improved to reduce the size of the dispatch table if
15716 compiling under restriction No_Dispatching_Calls plus code cleanup.
15717 Code reorganization plus removal of calls to Set_Num_Prim_Ops
15718 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.

15734 with CW_Membership.
15735 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Remove entries associated
15736 with Get_Access_Level, Get_Predefined_Prim_Op_Address,
15737 Get_Prim_Op_Address Get_RC_Offset, Get_Remotely_Callable, Inherit_DT,
15738 Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
15739 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15740 (Expand_Dispatching_Call): Replace generation of call to the run-time
15741 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15742 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15744 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15745 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15746 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15747 Build_Set_Prim_Op_Address.
15748 (Get_Remotely_Callable): Subprogram removed.
15749 (Init_Predefined_Interface_Primitives): Replace generation of call to
15750 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15753 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15754 First (Parameter_Associations ()) with the call to First_Actual that
15755 returns an actual parameter expression for both named and positional
15758 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15759 check violation of restriction No_Dispatching_Calls.
15760 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15761 controlling argument.
15763 * exp_util.ads, exp_util.adb (Type_May_Have_Bit_Aligned_Components): Use
15764 First/Next_Component_Or_Discriminant
15765 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15766 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15767 specify Any_Limited_Interface, and this functionality is already
15768 provided by the function Has_Abstract_Interfaces.
15769 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15770 support concurrent types implementing interfaces.
15771 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15772 specify kind Any_Limited_Interface, and this functionality is already
15773 provided by the function Has_Abstract_Interfaces.
15774 (Remove_Side_Effects): replace Controlled_Type by
15775 CW_Or_Controlled_Type whenever the issue is related to
15776 using or not the secondary stack.
15778 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15779 P_Interface_Type_Definition to fulfill the new interface (the formal
15780 Is_Synchronized is no longer required).
15782 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
15783 Update dependencies.
15785 * exp_atag.ads, exp_atag.adb: New file

15789 Cyrille Comar <comar@adacore.com>
15791 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15792 anonymous, use finalization list of enclosing dynamic scope.
15793 (Expand_N_Package_Declaration): For a library package declaration
15794 without a corresponding body, generate RACW subprogram bodies in the
15795 spec (just as we do for the task activation call).
15796 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15797 Is_Abstract_Type. Make sure these are called only when appropriate.
15798 Remove all code for DSP option
15799 (CW_Or_Controlled_Type): new subprogram.
15801 2007-04-06 Eric Botcazou <botcazou@adacore.com>
15802 Ed Schonberg <schonberg@adacore.com>
15803 Gary Dismukes <dismukes@adacore.com>
15805 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15806 parameter. If it is set to true, return a result capped according to
15807 the global upper bound for the index of an entry family.
15808 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15809 (Build_Find_Body_Index): Adjust for above change.
15810 (Entry_Index_Expression): Likewise.
15811 (Is_Potentially_Large_Family): New function extracted from...
15812 (Collect_Entry_Families): ...here. Call it to detect whether the family
15813 is potentially large.
15814 (Build_Entry_Count_Expression): If the family is potentially large, call
15815 Family_Size with 'Cap' set to true.
15816 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15817 a protected version of an operation declared in the private part of
15818 a protected object, because they may be invoked through a callback.
15819 (Set_Privals): If the type of a private component is an anonymous access
15820 type, do not create a new itype for each protected body.
15821 If the body of a protected operation creates
15822 controlled types (including allocators for class-widetypes), the
15823 body of the corresponding protected subprogram must include a
15825 (Build_Activation_Chain_Entity): Build the chain entity for extended
15827 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15828 to determine whether operation overrides an inherited primitive.
15829 (Build_Wrapper_Spec): Add code to examine the parents while looking
15830 for a possible overriding candidate.
15831 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15832 hold an actual parameter value since its initialization is separated
15833 from the the declaration. Prevents errors on null-excluding access
15836 2007-04-06 Thomas Quinot <quinot@adacore.com>
15837 Pablo Oliveira <oliveira@adacore.com>
15839 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15840 Do an Unchecked_Conversion to handle the passage from the Underlying
15841 Type to the Base Type when calling Build_To_Any_Call and
15842 Build_From_Any_Call.
15843 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15844 E_Constant, depending upon Variable formal.
15845 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15846 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15847 parameter that requires an extra constrained parameter, declare
15848 temporary for actual as a variable, not a constant.
15849 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15850 the unit being compiled is the one that contains the stub type.
15851 Change primitive operation name for the RACW associated with a RAS
15852 from Call to _Call so it cannot clash with any legal identifier.
15853 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15855 (Append_RACW_Bodies): New subprogram.
15856 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15857 Add_Receiving_Stubs_To_Declarations functions.
15858 When expanding a package body, this list correspond to the
15859 statements in the HSS at the end of the pacakge.
15860 When expanding a package spec, this list correspond to the
15862 (Add_Receiving_Stubs_To_Declarations): Append the function
15863 registering the receiving stubs at the end of the 'Stmts' list.
15864 (RCI_Package_Locator): Pass the new Version generic formal when
15865 instantiating a RCI_Locator package.
15866 (Build_From_Any_Function): To compute the High bound for an
15867 unconstrained array actual, we add the Low bound with the length.
15868 Thus we must convert the low bound and the length to an appropriate
15869 type before doing the sum.
15870 (Build_Subprogram_Receiving_Stubs, PolyORB):
15871 * Retrieve the extra formals parameters at the
15872 end of the parameter stream.
15873 * Use Move_Any_Value to write back out parameters
15874 after executing the request as it is more efficient
15875 than Copy_Any_Value.
15876 * Build the any containing Extra Formals with the
15877 appropriate typecode.
15878 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15879 empty Component_List.
15880 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15881 the tree the declaration for an object that serves as actual parameter
15882 in server-side stubs.
15883 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15884 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
15885 Use Build_Actual_Object_Declaration to prepare the actuals.

15892 function with the first not implicit parent type.
15893 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15894 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15895 typecode from the Etype. Therefore we retrieve the correct typecode
15896 with a call to Get_Any_Type.
15897 (Copy_Specification): Do controlling formal type substitution based on
15898 Is_Controlling_Formal flag, instead of caller-provided object type.
15899 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15900 a RACW primitive operation, we might get a subprogram declaration for an
15901 ancestor of the RACW designated type (not for the designated type
15902 itself), in the case where this operation is inherited. In this case we
15903 have no easy means of determining the original tagged type for which
15904 the primitive was declared, so instead we now rely on
15905 Copy_Specification to use the Is_Controlling_Formal flag to determine
15906 which formals require type substitution.

15912 GNAT.Current_Exception are not allowed if pragma Restrictions
15913 (No_Exception_Propagation) is set and in any case make the associated
15914 handler unsuitable as a target for a local raise statement.
15915 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15916 run-time subprogram CW_Membership by call to Build_CW_Membership.
15917 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15918 by a function call, a temporary must be created before expanding the
15919 Constructor_Call itself, to prevent out-of-order elaboration in the
15920 back-end when stack checking is enabled..
15922 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15924 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15925 result are the bounds of the left operand, not the right.
15927 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15930 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15936 Bob Duff <duff@adacore.com>
15938 * sem_aggr.adb (Resolve_Record_Aggregate): In semantics-only mode treat
15939 an association with a box as providing a value even though the
15940 initialization procedure for the type is not available.

15942 box corresponds to a component of the type.
15943 (Resolve_Record_Aggregate): Split Is_Abstract flag into
15944 Is_Abstract_Subprogram and Is_Abstract_Type.

15959 offering facilities for all the Vector/View conversion routines
15960 implemented by this unit.

16047 * mingw32.h (S2WSU): New macro to convert from a string to a
16048 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16049 standard 8bits encoding.
16050 (WS2SU): As above but converting from wide-sring to string.
16051 This is needed as it is necessary to have access to both versions in the
16052 runtime for the form parameter encoding support.
16053 This set of patch add support for the encoding form parameter.
16054 (S2WS): Improve implementation to handle cases where the filename is not
16055 UTF-8 encoded. In this case we default to using the current code page
16056 for the conversion.
16058 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16059 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16068 corresponding encoding value into AFCB structure.
16069 (Reset): Pass the encoding value to freopen.

16103 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16104 __gnat_adjust_context_for_raise.
16105 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16106 implementation of floating point operations as native x86 targets.
16107 So the FPU should be initialized in the same way using finit. Fix
16108 floating point operations accuracy issues.
16109 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16110 member in struct sigaction, so as to avoid warning for incompatible

16126 Javier Miranda <miranda@adacore.com>
16128 * lib-xref.ads, lib-xref.adb:
16129 Modify the loop that collects type references, to include interface
16130 types that the type implements. List each of these interfaces when
16131 building the entry for the type.
16132 (Generate_Definition): Initialize component Def and Typ of new entry
16133 in table Xrefs, to avoid to have these components unitialized.
16134 (Output_References): Split Is_Abstract flag into
16135 Is_Abstract_Subprogram and Is_Abstract_Type.
16136 (Generate_Reference): Add barrier to do not generate the warning
16137 associated with Ada 2005 entities with entities generated by the

16177 2007-04-06 Robert Dewar <dewar@adacore.com>
16179 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16180 it no longer destroys the contents of Name_Buffer or Name_Len and
16181 non-standard and invalid names are handled better.
16182 (Get_Decoded_Name_String): Improve performance by using
16183 Name_Has_No_Encodings flag in the name table.
16184 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16185 Used for debugging printouts.

16188 Javier Miranda <miranda@adacore.com>
16189 Bob Duff <duff@adacore.com>
16191 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16192 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16193 there is no need to generate always a record_definition_node in case
16194 of synchronized interface types.
16195 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16196 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16197 illegal in Ada 95, in cases where it is legal. Change the warnings to
16198 errors in other cases. Don't give the error unless the "not null"
16199 parses properly. Correct the source position at which the error occurs.
16200 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16201 P_Null_Exclusion, to suppress "not null" warnings.

16203 associated goto statements.
16205 * par-endh.adb (Pop_End_Context): Allow more flexibility in placement

16253 Entry for pragma Unreferenced_Objects
16255 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16256 switches, without repetition of "eD". Make sure that last character of
16257 -gnatep= switch is not taken as -gnat switch character.
16258 Complete rewrite of circuit for handling saving compilation options

16277 the default project path, initially done during elaboration of the
16279 If the prefix returned by Sdefault is null, get the prefix from a call
16280 to Executable_Prefix_Path.
16281 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16284 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16285 canonical directory name to open the directory from which files are
16287 (Record_Other_Sources): Idem.
16288 (Locate_Directory): Add the possibility to create automatically missing
16289 directories when Setup_Projects is True.
16290 Call Locate_Directory so that the directory will be created when
16291 Setup_Projects is True, for object dir, library dir, library ALI dir,
16292 library source copy dir and exec dir.
16294 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16297 2007-04-06 Robert Dewar <dewar@adacore.com>

16331 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16332 full word is no longer compared twice.
16334 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16336 * sem_ch10.adb (Install_Limited_Context_Clauses.
16337 Expand_Limited_With_Clause): Use a new copy of selector name in the
16338 call to Make_With_Clause. This fixes the tree structure for ASIS
16339 purposes. Nothing is changed in the compiler behaviour.
16340 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16341 a package renaming.
16342 (Install_Limited_With_Clauses): Do not install non-limited view when it
16343 is still incomplete.
16345 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16346 Gary Dismukes <dismukes@adacore.com>
16348 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16349 when capturing size information, instead of base type, which for a
16350 formal array type will be the unconstrained type.
16351 (Analyze_Formal_Object_Declaration): Add check for illegal default
16352 expressions for a formal in object of a limited type.
16353 (Instantiate_Object): Ditto.
16354 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16355 because they were defaulted in the formal package and no check applies
16357 (Check_Formal_Package_Instance): Extend conformance check to other
16358 discrete types beyond Integer.
16359 (Process_Default): Copy directly the unmatched formal. A generic copy
16360 has already been performed in Analyze_Formal_Package.
16361 (Analyze_Associations): If a formal subprogram has no match, check for
16362 partial parametrization before looking for a default, to prevent
16364 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16365 not set the instantiation environment before analyzing the actuals.
16366 Fixes regression on 8515-003 with implementation of AI-133.
16367 Set_Instance_Env checks whether the generic unit is a predefined
16368 unit, in which case the instance must be analyzed with the latest Ada
16369 mode. This setting must take place after analysis of the actuals,
16370 because the actuals must be analyzed and frozen in the Ada mode extant
16371 outside of the current instantiation.
16372 (Save_Env, Restore_Env): Preserve and restore the configuration
16373 parameters so that predefined units can be compiled in the proper Ada
16375 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16376 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16377 and Is_Abstract_Type.
16378 (Analyze_Formal_Package): For better error recovery, Add exception
16379 handler to catch Instantion_Error, which can be raised in
16380 Analyze_Associations
16382 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16383 Bob Duff <duff@adacore.com>
16384 Gary Dismukes <dismukes@adacore.com>
16386 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16387 prefix type is a discriminated subtype of the type of the formal.
16388 (Analyze_Allocator): Collect all coextensions regardless of the context.
16389 Whether they can be allocated statically is determined in exp_ch4.
16390 (Analyze_Selected_Component): If the prefix is a limited view and the
16391 non-limited view is available, use the non-limited one.
16392 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16393 therefore illegal), suggest a qualified expression rather than a type
16394 conversion, because a type conversion would be illegal in this context.
16395 (Anayze_Allocator): Trace recursively all nested allocators so that all
16396 coextensions are on the corresponding list for the root. Do no mark
16397 coextensions if the root allocator is within a declaration for a stack-
16398 allocated object, because the access discriminants will be allocated on
16400 (Analyze_Call): Remove restriction on calls to limited functions for the
16401 cases of generic actuals for formal objects, defaults for formal objects
16402 and defaults for record components.
16403 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16404 element list. Their expansion is delayed until the enclosing allocator
16405 is processed and its finalization list constructed.
16406 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16407 for an operation with the given name among the primitive operations of
16408 the corresponding record type.
16409 (Analyze_Selected_Component): If the prefix is a task type that
16410 implements an interface, and there is no entry with the given name,
16411 check whether there is another primitive operation (e.g. a function)
16413 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16414 properly the indexing of a function call written in prefix form, where
16415 the function returns an array type, and all parameters of the function
16416 except the first have defaults.
16417 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16418 the original operands, rather than relocating them, for efficiency and
16419 to work properly when an operand is overloaded.
16420 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16421 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16422 (Analyze_Selected_Component): If the prefix is a private extension, only
16423 scan the visible components, not those of the full view.
16424 (Try_Primitive_Operation): If the operation is a procedure, collect all
16425 possible interpretations, as for a function, because in the presence of
16426 classwide parameters several primitive operations of the type can match
16427 the given arguments.
16429 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16430 Robert Dewar <dewar@adacore.com>
16432 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16433 tag-indeterminate call to an abstract function, when the left-hand side
16435 (Analyze_Loop_Statement): Improve detection of infinite loops
16437 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16438 Thomas Quinot <quinot@adacore.com>
16440 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16441 out of Analyze_Package_Declaration, because processing must be applied
16442 to package bodies as well, for deferred constants completed by pragmas.
16443 (Analyze_Package_Declaration): When the package declaration being
16444 analyzed does not require an explicit body, call Check_Completion.
16445 (May_Need_Implicit_Body): An implicit body is required when a package
16446 spec contains the declaration of a remote access-to-classwide type.
16447 (Analyze_Package_Body): If the package contains RACWs, append the
16448 pending subprogram bodies generated by exp_dist at the end of the body.
16449 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16450 Is_Abstract_Subprogram and Is_Abstract_Type.
16451 (Preserve_Full_Attributes): The full entity list is not an attribute
16452 that must be preserved from full to partial view.
16454 * sem_dist.adb (Add_RAS_Dereference_TSS):
16455 Change primitive name to _Call so it cannot clash with any legal
16456 identifier, and be special-cased in Check_Completion.
16457 Mark the full view of the designated type for the RACW associated with
16458 a RAS as Comes_From_Source to get proper view switching when installing
16459 private declarations.
16460 Provite a placeholder nested package body along with the nested spec
16461 to have a place for Append_RACW_Bodies to generate the calling stubs
16462 and stream attributes.
16464 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16465 Robert Dewar <dewar@adacore.com>
16467 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16468 that is a limited view, check the non-limited view if available.
16469 (Undefined): Refine error message for missing with of Text_IO
16470 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16471 to distinguish real missing with cases.
16472 Fix format of all missing with messages
16473 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16474 renaming as body when renamed entity is abstract.
16476 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16477 Javier Miranda <miranda@adacore.com>
16479 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16480 predicate recursive, to handle complex expressions on literals whose
16481 spurious ambiguity comes from the abstract interpretation of some
16483 (Interface_Present_In_Ancestor): Add support to concurrent record
16485 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16486 Is_Abstract_Subprogram and Is_Abstract_Type.
16488 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16489 Javier Miranda <miranda@adacore.com>
16491 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16492 dereference of a local object R created as a reference to another
16493 object O, use the access level of O.
16494 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16495 rather than local Same_Formal_Type, to check whether protected operation
16496 overrides an inherited one.
16497 (Same_Formal_Type): New predicate, used when matching signatures of
16498 overriding synchronized operations, to handle the case when a formal
16499 has a type that is a generic actual.
16500 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16501 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16502 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16503 syntactic ambiguities involving indexing of function calls that return
16505 (Abstract_Interface_List): New subprogram that returns the list of
16506 abstract interfaces associated with a concurrent type or a
16507 concurrent record type.
16508 (Interface_Present_In_Parent): New subprogram used to check if a
16509 given type or some of its parents implement a given interface.
16510 (Collect_Abstract_Interfaces): Add support for concurrent types
16511 with interface types.
16512 (Has_Abstract_Interfaces): Add support for concurrent types with
16514 (Is_Parent): New subprogram that determines whether E1 is a parent
16515 of E2. For a concurrent type its parent is the first element of its
16516 list of interface types; for other types this function provides the
16517 same result than Is_Ancestor.
16518 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16519 (Collect_Synchronized_Interfaces): Removed because the subprogram
16520 Collect_Abstract_Interfaces provides this functionality.
16521 (Collect_Abstract_Interfaces): Minor update to give support to
16522 concurrent types and thus avoid undesired code duplication.
16523 (Get_Subprogram_Entity): Handle entry calls.
16524 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16526 (Enter_Name): Do not give -gnatwh hiding warning for record component
16527 entities, they never result in hiding.

16530 Robert Dewar <dewar@adacore.com>
16532 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
16533 to chain nested components that are allocators for access discriminants
16534 of the enclosing object.
16535 Add N_Push and N_Pop nodes
16536 New field Exception_Label added
16537 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16538 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
16539 (Is_Coextension): New flag for allocators, to mark allocators that
16540 correspond to access discriminants of dynamically allocated objects.
16541 (N_Block_Statement): Document the fact that the corresponding entity
16542 can be an E_Return_Statement.
16543 (Is_Coextension): New flag for allocators.
16544 Remove all code for DSP option
16546 * sprint.ads, sprint.adb: Display basic information for class_wide
16547 subtypes. Add handling of N_Push and N_Pop nodes
16549 2007-04-06 Arnaud Charlet <charlet@adacore.com>
16551 * s-tpobop.adb (Exceptional_Complete_Entry_Body): Undefer abortion
16552 before propagating exception.
16554 2007-04-06 Olivier Hainque <hainque@adacore.com>
16556 * tracebak.c (PC_ADJUST - ia64): -4 instead of -16, expected to yield
16557 an address always within the call instruction from a return address.
16559 2007-04-06 Olivier Hainque <hainque@adacore.com>
16560 Eric Botcazou <botcazou@adacore.com>
16562 * trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
16563 expression with a COMPOUND_EXPR including the call instead of emitting
16564 the call directly here.
16565 (gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
16566 high bound is constant and the slice is empty. Tidy.
16567 (tree_transform, case N_Op_Not): Handle properly the case where the
16568 operation applies to a private type whose full view is a modular type.
16569 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16570 Address_Clause, use the associated Expression as the GNAT tree
16571 representing the choice value to ensure the corresponding GCC tree is
16572 of the proper kind.
16573 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16574 instead of just the operands, as the base GCC stabilize_reference does.
16575 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16576 requested; otherwise fail.
16577 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
16579 2007-04-06 Thomas Quinot <quinot@adacore.com>
16581 * uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
16582 implementation of UI_Div.
16583 (UI_Div): Reimplement as a call to UI_Div_Rem.
16584 (UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
16585 remainder, avoiding the cost of a multiplication and a subtraction.
16586 (UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
16587 provides both quotient and remainder in a single computation.

16857 anonymous access types.
16858 (Valid_Conversion): For a conversion to a numeric type occurring in an
16859 instance or inlined body, no need to check that the operand type is

17565 the parent part is a build-in-place function call, generate assignments.
17566 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17567 are build-in-place function calls.
17568 (Replace_Self_Reference): New subsidiary of
17569 Make_OK_Assignment_Statement, to replace an access attribute that is a
17570 self-reference into an access to the appropriate component of the
17571 target object. Generalizes previous mechanism to handle self-references
17572 nested at any level.
17573 (Is_Self_Referential_Init): Remove, not needed.
17574 (Is_Self_Referential_Init): New predicate to simplify handling of self
17575 referential components in record aggregates.
17576 (Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
17577 check for presence of entity before checking for self-reference.
17578 (Has_Default_Init_Comps): Return True if a component association is a
17579 self-reference to the enclosing type, which can only come from a
17580 default initialization.
17581 (Make_OK_Assignment_Statement): If the expression is of the form
17582 Typ'Acc, where Acc is an access attribute, the expression comes from a
17583 default initialized self-referential component.
17584 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17585 that has been derived from several abstract interfaces we must also
17586 initialize the tags of the secondary dispatch tables.

17591 Robert Dewar <dewar@adacore.com>
17594 (Expand_Access_To_Protected_Op): If the context indicates that an access
17595 to a local operation may be transfered outside of the object, create an
17596 access to the wrapper operation that must be used in an external call.
17597 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17598 target, pass the Valid attribute applied to a floating-point prefix on
17599 to the back end without expansion.
17600 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17601 the allocated storage when it is specified by a per-object expression.
17602 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17603 Nothing to do here, the attribute has been rewritten during semantic

17607 (Find_Fat_Info): Handle case of universal real
17608 (Expand_Access_To_Protected_Op): Fix use of access to protected
17609 subprogram from inside the body of a protected entry.

17612 into a fat pointer.
17613 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17614 subcomponent's enclosing variable is aliased with a constrained subtype.
17615 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17616 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17617 an aliased prefix must be known to be constrained in order to use True
17618 for the attribute value, and now it's possible for some aliased views
17619 to be unconstrained.
17621 2006-10-31 Robert Dewar <dewar@adacore.com>
17623 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17624 (Expand_Entity_Reference): Correct error of not handling subprogram
17625 formals in current_value processing.
17627 2006-10-31 Javier Miranda <miranda@adacore.com>

17630 Gary Dismukes <dismukes@adacore.com>
17632 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17633 register in the final list objects containing class-wide interfaces;
17634 otherwise we incorrectly register the tag of the interface in the final
17636 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17637 generate the wrapper if the parent primitive is abstract. This is
17638 required to report the correct error message.
17639 (Expand_N_Subtype_Indication): Do validity checks on range
17640 (Clean_Task_Names): If an initialization procedure includes a call to
17641 initialize a task (sub)component, indicate that the procedure will use
17642 the secondary stack.
17643 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17644 compatibility for interfacing with CPP by default.
17645 (Expand_N_Object_Declaration): Only build an Adjust call when the
17646 object's type is a nonlimited controlled type.
17647 * exp_ch3.adb: Add with and use of Exp_Ch6.
17648 (Expand_N_Object_Declaration): Check for object initialization that is a
17649 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17650 Object_Declaration to the call.
17651 (Freeze_Type): When the designated type of an RACW was not frozen at the
17652 point where the RACW was declared, validate the primitive operations
17653 with respect to E.2.2(14) when it finally is frozen.
17654 (Build_Initialization_Call,Expand_Record_Controller): Rename
17655 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17656 return-by-reference has no meaning in Ada 2005.
17657 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17658 to register tag of the immediate ancestor interfaces in the
17659 run-time structure.
17660 (Init_Secondary_Tags): Moved to the specification to allow the
17661 initialization of extension aggregates with abstract interfaces.
17662 (Build_Master_Renaming): Make public, for use by function declarations
17663 whose return type is an anonymous access type.
17664 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17665 Insert_List_Before_And_Analyze after the generation of the specs
17666 associated with null procedures.
17667 (Expand_Tagged_Root): Update documentation in its specification.
17668 (Init_Secondary_Tags): Update documentation.
17669 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17670 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17671 then generate code to inherit the contents of the dispatch table
17672 directly from the ancestor.
17673 (Expand_Record_Controller): Insert controller component after tags of
17674 implemented interfaces.
17675 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17676 create null procedure overridings when null procedures are inherited
17678 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17679 declarations for overriding null primitives inherited from interfaces.
17680 (Is_Null_Interface_Procedure): New function in
17681 Make_Null_Procedure_Specs.
17682 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17683 immediate ancestor of a tagged type is an abstract interface type we
17684 must generate the specification of the predefined primitives associated
17685 with controlled types (because the dispatch table of the ancestor is
17686 null and hence these entries cannot be inherited). This is required to
17687 elaborate well the dispatch table.

17695 * exp_ch4.adb (Expand_N_Type_Conversion): Handle missing interface type
17697 (Expand_N_In): Do validity checks on range
17698 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17699 (Expand_N_Allocator): For "new T", if the object is constrained by
17700 discriminant defaults, allocate the right amount of memory, rather than
17701 the maximum for type T.
17702 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17703 when the allocator is initialized by a build-in-place call, since the
17704 allocator is already rewritten as a reference to the function result,
17705 and this prevents an unwanted duplication of the function call.
17706 Add with and use of Exp_Ch6.
17707 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17708 is a call to build-in-place function and apply
17709 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17710 untagged designated types).
17711 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17712 optimization if source or target is biased.
17713 (Expand_N_Allocator): Add comments for case of an allocator within a
17714 function that returns an anonymous access type designating tasks.
17715 (Expand_N_Allocator): apply discriminant checks for access
17716 discriminants of anonymous access types (AI-402, AI-416)

17725 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17726 (Expand_N_Assignment_Statement): Call
17727 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17728 build-in-place function call. Currently, this can happen only for
17729 assignments that come from aggregates.
17730 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17731 in order to alleviate the upward compatibility introduced by AI-318.
17732 (Expand_N_Extended_Return_Statement): Add support for handling the
17733 return object as a build-in-place result.
17734 (Expand_Non_Function_Return): Implement simple return statements nested
17735 within an extended return.
17736 (Enable_New_Return_Processing): Turn on the new processing of return
17738 (Expand_Non_Function_Return): For a return within an extended return,
17739 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17740 (Expand_N_Extended_Return_Statement): Implement AI-318
17741 (Expand_Simple_Function_Return): Ditto.
17742 (Expand_N_If_Statement): Handle new -gnatwt warning

17744 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17745 a protected object.
17746 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17747 validity checking of assignments to elementary record components.
17748 (Expand_N_Return_Statement): return Class Wide types on the secondary
17749 stack independantly of their controlled status since with HIE runtimes,
17750 class wide types are not potentially controlled anymore.
17752 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17755 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17756 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17757 it expects a block, procedure, or task. The return statement will get
17758 turned into a block, and Expand_Cleanup_Actions will happen then.
17760 2006-10-31 Robert Dewar <dewar@adacore.com>
17761 Ed Schonberg <schonberg@adacore.com>
17762 Bob Duff <duff@adacore.com>
17763 Gary Dismukes <dismukes@adacore.com>
17765 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17767 (Expand_Inlined_Call): Tagged types are by-reference types, and
17768 therefore should be replaced by a renaming declaration in the expanded
17769 body, as is done for limited types.
17770 (Expand_Call): If this is a call to a function with dispatching access
17771 result, propagate tag from context.
17772 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17774 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17775 build-in-place when the right-hand side of an assignment is a
17776 build-in-place function call.
17777 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17778 of the explicit dereference of the allocator to the result subtype of
17779 the build-in-place function. This is needed to satisfy type checking
17780 in cases where the caller's return object is created by an allocator for
17781 a class-wide access type and the type named in the allocator is a
17783 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17784 conversion of the reference to the declared object to the result subtype
17785 of the build-in-place function. This is needed to satisfy type checking
17786 in cases where the declared object has a class-wide type. Also, in the
17787 class-wide case, change the type of the object entity to the specific
17788 result subtype of the function, to avoid passing a class-wide object
17789 without explicit initialization to the back end.
17790 (Register_Interface_DT_Entry): Moved outside the body of
17791 Freeze_Subprogram because this routine is now public; it is called from
17792 Check_Dispatching_Overriding to handle late overriding of abstract
17793 interface primitives.
17794 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17795 adding an implicit access actual on a call to a build-in-place function.
17796 (Expand_Actuals): Test for an actual parameter that is a call to a
17797 build-in-place function and apply
17798 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17799 (Is_Build_In_Place_Function): New function to determine whether an
17800 entity is a function whose calls should be handled as build-in-place.
17801 (Is_Build_In_Place_Function_Call): New function to determine whether an
17802 expression is a function call that should handled as build-in-place.
17803 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17804 calls to build-in-place functions as the initialization of an allocator.
17805 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17806 handling calls to build-in-place functions in contexts that do not
17807 involve init of a separate object (for example, actuals of subprogram
17809 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17810 handling calls to build-in-place functions as the initialization of an
17811 object declaration.

17813 instantiation of Traverse_Body to avoid unreferenced warning.
17814 (Check_Overriding_Inherited_Interfaces): Removed.
17815 (Register_Interface_DT_Entry): Code cleanup.
17816 (Register_Predefined_DT_Entry): Code cleanup.
17817 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17818 inlined statements if within a transient scope.
17819 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17820 formal parameters with occurrences of actuals in inlined body, establish
17821 visibility on the proper view of the actual's subtype for the body's
17823 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17824 compatibility mode and we have an imported CPP subprogram because
17825 for now we assume that imported CPP primitives correspond with
17826 objects whose constructor is in the CPP side (and therefore we
17827 don't need to generate code to register them in the dispatch table).
17828 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17829 aligned selected component.
17830 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17831 the actual of an in-mode parameter is a type conversion.
17832 (Expand_Actuals): If the call does not come from source and the actual
17833 is potentially misaligned, let gigi handle it rather than rejecting the
17834 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17835 Class Wide types as returning by reference independantly of their
17836 controlled status since with HIE runtimes class wide types are not
17837 potentially controlled anymore.
17839 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17841 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17842 references that are private components of the protected object.

17844 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17845 instantiation to deal with warnings.

17852 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17853 initialization of Homonym_Len.
17854 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17855 names from fully qualified name. Fixes problem of duplicate
17856 external names differing only in the presence of such a block name.
17858 2006-10-31 Thomas Quinot <quinot@adacore.com>
17859 Pablo Oliveira <oliveira@adacore.com>
17861 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17862 subprogram Ids, even if they are not yet assigned.
17863 (Build_Subprogram_Id): It is now this function that will take care of
17864 calling Assign_Subprogram_Ids if necessary.
17865 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17866 should be done only once they are assigned.
17867 (Build_From_Any_Function, case of tagged types): Add missing call to

17870 type for an RACW type.
17871 (Add_RACW_Features): When processing an RACW declaration for which the
17872 designated type is already frozen, enforce E.2.2(14) rules immediately.
17873 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17874 special reordering of controlling formals.
17876 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the

17879 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17881 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17882 fixed-point operations in an integer context, i.e. as operands of a
17883 conversion to an integer type, indicate that result must be rounded.
17885 2006-10-31 Robert Dewar <dewar@adacore.com>
17887 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17888 cases, pass the encoding method, since it is now required by the run
17891 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17892 assumption that Str'First = 1.
17893 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17894 it on to the Value_Wide_Wide_Character call.
17895 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17896 properly handles a string of the form quote-encoded_wide_char-quote.
17898 * s-wchcnv.adb: Minor reformatting
17900 2006-10-31 Javier Miranda <miranda@adacore.com>

17903 run-time membership test to ensure that the constructed object
17904 implements the target abstract interface.
17906 2006-10-31 Robert Dewar <dewar@adacore.com>
17908 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17909 Machine_Attribute pragma internally to implement the user pragma.
17910 Add processing for pragma Interface so that it is now completely
17911 equivalent to pragma Import.
17913 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17914 so that it can be applied to all entities, including record components
17915 and enumeration literals.
17916 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17917 priority ranges are correct, verify compatibility against task
17918 dispatching and locking policies, and if everything is correct an entry
17919 is added to the table containing priority specific dispatching entries
17920 for this compilation unit.
17921 (Delay_Config_Pragma_Analyze): Delay processing
17922 Priority_Specific_Dispatching pragmas because when processing the
17923 pragma we need to access run-time data, such as the range of
17924 System.Any_Priority.
17925 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17926 Allow pragma Unreferenced as a context item
17927 Add pragma Preelaborable_Initialization
17928 (Analyze_Pragma, case Interface): Interface is extended so that it is
17929 now syntactically and semantically equivalent to Import.
17930 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17931 insertion characters.
17932 Add handling for Pragma_Wide_Character_Encoding
17933 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17934 never supercedes a real restriction, and that a real restriction
17935 always supercedes a warning.
17936 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17940 Ed Schonberg <schonberg@adacore.com>
17941 Robert Dewar <dewar@adacore.com>
17943 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17944 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17945 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17947 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17948 type of the function containing a return statement, because the
17949 Return_Type field was removed. We now use the Return_Applies_To field.
17951 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17952 (Build_Task_Image_Decl): If procedure is not called from an
17953 initialization procedure, indicate that function that builds task name
17954 uses the sec. stack. Otherwise the enclosing initialization procedure
17955 will carry the indication.
17956 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17957 N_Object_Declaration instead.
17958 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17959 conditional dead code killed, and change implementation accordingly.
17960 (Insert_Actions): Add N_Return_Object_Declaration case.
17961 Correct comment to mention N_Extension_Aggregate node.
17962 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17963 attempts to save information for global variables which cannot be
17965 (Get_Current_Value_Condition): Handle conditions the other way round
17966 (constant on left). Also handle right operand of AND and AND THEN
17967 (Set_Current_Value_Condition): Corresponding changes
17968 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17969 (Get_Current_Value_Condition): Handle simple boolean operands
17970 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17971 (Get_Current_Value_Condition): If the variable reference is within an
17972 if-statement, does not appear in the list of then_statments, and does
17973 not come from source, treat it as being at unknown location.
17974 (Get_Current_Value_Condition): Enhance to allow while statements to be
17975 processed as well as if statements.
17976 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17978 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17979 of loop. This is safe now that we fixed Kill_Current_Values.
17980 (OK_To_Do_Constant_Replacement): Check whether current scope is
17981 Standard, before examining outer scopes.
17983 2006-10-31 Vincent Celier <celier@adacore.com>
17985 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17986 When True, apply VMS treatment to children of packages A, G, I and S.
17989 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17991 2006-10-31 Robert Dewar <dewar@adacore.com>
17992 Ed Schonberg <schonberg@adacore.com>
17994 * freeze.adb: Add handling of Last_Assignment field
17995 (Warn_Overlay): Supply missing continuation marks in error msgs
17996 (Freeze_Entity): Add check for Preelaborable_Initialization
17998 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18000 * g-expect.adb: Add Warnings (Off) to prevent new warning
18002 * lib-xref.adb: Add handling of Last_Assignment field
18003 (Generate_Reference): Centralize handling of pragma Obsolescent here
18004 (Generate_Reference): Accept an implicit reference generated for a
18005 default in an instance.
18006 (Generate_Reference): Accept a reference for a node that is not in the
18007 main unit, if it is the generic body corresponding to an subprogram
18010 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18012 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18014 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18016 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18017 use clauses, to avoid messages on packages used to qualify, and also
18018 to avoid messages from obsolescent units.
18019 (Warn_On_Useless_Assignments): Don't generate messages for imported
18020 and exported variables.
18021 (Warn_On_Useless_Assignments): New procedure
18022 (Output_Obsolescent_Entity_Warnings): New procedure
18023 (Check_Code_Statement): New procedure
18025 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18026 Change name Is_Ada_2005 to Is_Ada_2005_Only
18027 (Last_Assignment): New field for useless assignment warning
18029 2006-10-31 Olivier Hainque <hainque@adacore.com>
18031 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18032 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18034 2006-10-31 Bob Duff <duff@adacore.com>
18035 Robert Dewar <dewar@adacore.com>
18036 Ed Schonberg <schonberg@adacore.com>
18038 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18039 Ada 95 mode, because it violates the new rules for AI-318.
18041 * g-awk.ads: Use overloaded subprograms in every case where we used to
18042 have a default of Current_Session. This makes the code closer to be
18043 correct for both Ada 95 and 2005.
18045 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18046 code, relying on the fact that the compiler generates a warning
18047 instead of an error in -gnatg mode.
18049 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18050 E_Return_Statement entity kind.
18051 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18053 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18054 report an error if the reserved word abstract has been previously found.
18055 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18057 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18058 parenthesized range attribute usage
18059 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18061 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18062 in the syntax for extended_return_statement. This is not in the latest
18063 RM, but the ARG is expected to issue an AI allowing this.
18064 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18065 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18066 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18067 P_Return_Statement): Parse the new syntax for extended_return_statement.
18069 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18070 Output_End_Missing): Add error-recovery code for the new
18071 extended_return_statement syntax; that is, the new E_Return entry on
18074 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18075 limited to nonlimited, because otherwise we violate the new Ada 2005
18076 rules about returning limited types in function Create_AST_Handler in
18079 * sem.adb (Analyze): Add cases for new node kinds
18080 N_Extended_Return_Statement and N_Return_Object_Declaration.
18082 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18083 type is in the same category as type of context before applying check,
18084 to prevent anomalies in instantiations.
18085 (Resolve_Aggregate): Remove test for limited components in aggregates.
18086 It's unnecessary in Ada 95, because if it has limited components, then
18087 it must be limited. It's wrong in Ada 2005, because limited aggregates
18089 (Resolve_Record_Aggregate): Move check for limited types later, because
18090 OK_For_Limited_Init requires its argument to have been resolved.
18091 (Get_Value): When copying the component default expression for a
18092 defaulted association in an aggregate, use the sloc of the aggregate
18093 and not that of the original expression, to prevent spurious
18094 elaboration errors, when the expression includes function calls.
18095 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18096 were missing. We also didn't handle qualified expressions. Now also
18097 allow function calls. Use new common routine OK_For_Limited_Init.
18098 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18099 with space can upper case letter).
18101 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18102 Has_Static_Discriminants flag
18103 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18104 type with discriminants.
18105 (Process_Range_Expr_In_Decl): Do validity checks on range
18106 (Build_Discriminant_Constraints): Use updated form of
18107 Denotes_Discriminant.
18108 (Process_Subtype): If the subtype is a private subtype whose full view
18109 is a concurrent subtype, introduce an itype reference to prevent scope
18111 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18112 Record_Type_Declaration): The functionality of the subprograms
18113 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18114 is now performed by a single routine.
18115 (Build_Derived_Record_Type): If the type definition includes an explicit
18116 indication of limitedness, then the type must be marked as limited here
18117 to ensure that any access discriminants will not be treated as having
18118 a local anonymous access type.
18119 (Check_Abstract_Overriding): Issue a detailed error message when an
18120 abstract subprogram was not overridden due to incorrect mode of its
18122 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18123 synchronized private extension declarations. Verify that the ancestor is
18124 a limited or synchronized interface or in the generic case, the ancestor
18125 is a tagged limited type or synchronized interface and all progenitors
18126 are either limited or synchronized interfaces.
18127 Derived_Type_Declaration): Check for presence of private extension when
18128 dealing with synchronized formal derived types.
18129 Process_Full_View): Enchance the check done on the usage of "limited" by
18130 testing whether the private view is synchronized.
18131 Verify that a synchronized private view is completed by a protected or
18133 (OK_For_Limited_Init_In_05): New function.
18134 (Analyze_Object_Declaration): Move check for limited types later,
18135 because OK_For_Limited_Init requires its argument to have been resolved.
18136 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18137 in order to alleviate the upward compatibility introduced by AI-318.
18138 (Constrain_Corresponding_Record): If the constraint is for a component
18139 subtype, mark the itype as frozen, to avoid out-of-scope references to
18140 discriminants in the back-end.
18141 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18142 this subprogram against wrong sources.
18143 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18144 discriminant of limited type completed with a protected type, when the
18145 discriminant is used to constrain a private component of the type, and
18146 expansion is disabled.
18147 (Find_Type_Of_Object): Do not treat a return subtype that is an
18148 anonymous subtype as a local_anonymous_type, because its accessibility
18149 level is the return type of the enclosing function.
18150 (Check_Initialization): In -gnatg mode, turn the error "cannot
18151 initialize entities of limited type" into a warning.
18152 (OK_For_Limited_Init): Return true for generated nodes, since it
18153 sometimes violates the legality rules.
18154 (Make_Incomplete_Declaration): If the type for which an incomplete
18155 declaration is created happens to be the currently visible entity,
18156 preserve the homonym chain when removing it from visibility.
18157 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18158 inherited subprograms.
18159 (Access_Definition): If this is an access to function that is the return
18160 type of an access_to_function definition, context is a type declaration
18161 and the scope of the anonymous type is the current one.
18162 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18163 incomplete subtype to the set of private dependents of the original
18165 (Constrain_Discriminated_Type): Emit an error message whenever an
18166 incomplete subtype is being constrained.
18167 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18168 corresponding subtype of the full view of the original incomplete type.
18169 (Check_Incomplete): Properly detect invalid usage of incomplete types
18172 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18174 * g-catiio.ads, g-catiio.adb (Value): New function.

18183 Robert Dewar <dewar@adacore.com>
18185 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18186 handling executable extension manually and duplicating code.
18188 * make.adb: Implement new -S switch
18189 (Gnatmake): Use new function Osint.Executable_Name instead
18190 of handling executable extension manually.
18192 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18193 is specified, the executable name ends with this suffix.
18194 Take advantage of Osint.Executable_Name instead of duplicating code.
18196 * switch-m.adb: Recognize new gnatmake -S switch
18198 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18200 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18203 * makeusg.adb: Add line for gnatmake -S switch
18205 2006-10-31 Vincent Celier <celier@adacore.com>
18207 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18208 call it with -static-libgcc, as there are some platforms, such as
18209 Darwin, where one of these two switches is compulsory to link.
18211 2006-10-31 Vincent Celier <celier@adacore.com>
18213 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18214 instead of ADA_PROJECT_PATH, for the project path.
18215 (Gnatls): When displaying the project path directories, use host dir
18218 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18219 names in the project path, as absolute paths may correspond to
18220 multi-valued VMS logical names.
18222 2006-10-31 Vincent Celier <celier@adacore.com>
18224 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18225 absolute path name.
18226 (Locate_Regular_File): Ditto
18227 (Change_Dir): Remove, no longer used
18228 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18229 on Windows. Get it calling Get_Current_Dir.
18230 (OpenVMS): Remove imported boolean, no longer needed.
18231 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18232 (Pid_To_Integer): New function to convert a Process_Id to Integer
18234 2006-10-31 Thomas Quinot <quinot@adacore.com>
18236 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18237 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18239 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18242 2006-10-31 Robert Dewar <dewar@adacore.com>
18244 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18245 initial letter o as a zero.

18249 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18251 2006-10-31 Robert Dewar <dewar@adacore.com>
18253 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18255 (Layout_Variant_Record): Retrieve the discriminants from the entity
18256 rather than from the type definition, because in the case of a full
18257 type for a private type we need to take the discriminants from the
18259 (Layout_Component_List): When applying the Max operator to variants with
18260 a nonstatic size, check whether either operand is static and scale that
18261 operand from bits to storage units before applying Max.
18262 (Layout_Type): In VMS, if a C-convention access type has no explicit
18263 size clause (and does not inherit one in the case of a derived type),
18264 then the size is reset to 32 from 64.
18266 2006-10-31 Vincent Celier <celier@adacore.com>
18268 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18269 its file has already been loaded, according to the unit being loaded,
18270 not to the current value of Multiple_Unit_Index.
18272 2006-10-31 Thomas Quinot <quinot@adacore.com>
18273 Eric Botcazou <ebotcazou@adacore.com>
18274 Arnaud Charlet <charlet@adacore.com>
18276 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18277 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18279 (a-except.o): Pass it to the compiler.
18280 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18281 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18282 a-calend-mingw.adb version.
18284 * Makefile.rtl: Added s-dsaser.
18285 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18286 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18287 Ada.Dispatching.Round_Robin.
18288 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18290 * Make-lang.in: Remove all references to gt-ada-decl.h.
18291 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18293 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18294 Update dependencies.
18296 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18298 2006-10-31 Vincent Celier <celier@adacore.com>
18300 * mlib-utl.adb (Initialized): Remove, no longer used
18301 (Initialize): Remove, no longer used
18302 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18303 if there is one, the archive indexer. Fail if the archive builder cannot
18305 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18308 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18310 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18311 Process_Body_Clauses): If the context of a body includes a use clause
18312 for P.Q then a with_clause for P in the same body is not redundant,
18313 even if the spec also has a with_clause on P.
18314 Add missing continuation mark to error msg
18315 (Build_Limited_Views): A limited view of a type is tagged if its
18316 declaration includes a record extension.
18317 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18318 node, even if the subunit has errors. This avoids malfunction by
18319 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18320 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18321 generation of obsolescent messages for with statements (cannot do
18322 this too early, or we cannot implement avoiding the messages in the
18323 case of obsolescent units withing obsolescent units).
18324 (Install_Siblings): If the with_clause is on a remote descendant of
18325 an ancestor of the current compilation unit, find whether there is
18326 a sibling child unit that is immediately visible.
18327 (Remove_Private_With_Clauses): New procedure, invoked after completing
18328 the analysis of the private part of a nested package, to remove from
18329 visibility the private with_clauses of the enclosing package
18331 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18332 now centralized in Generate_Reference.
18333 (Install_Limited_Context_Clauses): Remove superfluous error
18334 message associated with unlimited view visible through use
18335 and renamings. In addition, at the point in which the error
18336 is reported, we add the backslash to the text of the error
18337 to ensure that it is reported as a single error message.
18338 Use new // insertion for some continuation messages
18339 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18340 to create implicit with_clause for parent unit mentioned in original
18341 limited_with_clause.
18342 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18343 unit is a child unit. For ASIS queries.
18344 (Analyze_Subunit): If the subunit appears within a child unit, make all
18345 ancestor child units directly visible again.
18347 2006-10-31 Robert Dewar <dewar@adacore.com>
18349 * par-ch10.adb (P_Context_Clause): Minor error message fix

18358 P_Interface_Type_Definition.
18359 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18360 a formal object declaration with an access definition or a subtype mark
18361 with a null exclusion.
18362 (P_Generic_Association): Handle association with box, and others_choice
18363 with box, to support Ada 2005 partially parametrized formal packages.
18365 2006-10-31 Robert Dewar <dewar@adacore.com>
18366 Javier Miranda <miranda@adacore.com>
18368 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18369 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18370 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).

18378 object renaming declaration with an access definition or subtype mark
18379 with a possible null exclusion.

18406 of sources, even if it is not the first time, as it is for another
18408 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18409 dot, instead of replacing only the first '_'.
18411 * prj-part.adb (Parse): Convert project file path to canonical form
18413 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18414 extended, the project id of the project extending it is recorded in its
18415 data, even when it has already been processed as an imported project.
18417 2006-10-31 Robert Dewar <dewar@adacore.com>

18423 Robert Dewar <dewar@adacore.com>
18425 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18426 only a restriction warning is active for the given restriction. This is
18427 desirable because we do not want to modify code in the case where only
18429 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18430 causes overriding of real restrictions.
18431 Take advantage of new No_Restrictions constant.
18433 * raise.h: (__gnat_set_globals): Change profile.
18435 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18437 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18440 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18441 Move all the entities in obsolete package System.PolyORB_Interface to
18442 System.Partition_Interface.
18443 (RE_Storage_Size): New function in System.Tasking.

18460 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18461 properly an attempt to apply Unchecked_Access to a protected operation.
18462 (OK_Self_Reference): New subprogram to check the legality of an access
18463 attribute whose prefix is the type of an enclosing aggregate.
18464 Generalizes previous mechanism to handle attribute references nested
18465 arbitrarily deep within the aggregate.
18466 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18467 can appear in an aggregate if this is a default-initialized aggregate
18468 for a self-referential type.
18469 (Resolve_Attribute, case Access): Ditto.
18470 Add support for new implementation defined attribute Stub_Type.

18475 Has_Specified_Stream_Attribute flag.
18476 Disallow Storage_Size and Storage_Pool for access to subprogram
18477 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18478 access types of return subtypes in extended return statements. Remove
18479 accessibility checks on anonymous access types when Unchecked_Access is
18481 (Analyze_Attribute): Add support for the use of 'Class to convert
18482 a class-wide interface to a tagged type.
18483 Add support for the attribute Priority.
18484 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18485 whether the designated type is discriminated with a constrained partial
18486 view and require static matching in that case.
18487 Add local variable Des_Btyp. The Designated_Type
18488 of an access to incomplete subtype is either its non-limited view if
18489 coming from a limited with or its etype if regular incomplete subtype.
18491 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18492 Fix predicate to identify and allow cases of (expander-generated)
18493 references to tag of designated object of a RACW.
18494 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18495 non-static, and therefore cannot appear as a primary in a preelaborable
18497 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18498 Has_Read_Write_Attributes.
18499 (Has_Read_Write_Attributes): Reimplement in termes of
18500 Has_Stream_Attribute_Definition.
18501 (Missing_Read_Write_Attributes): When checking component types in a
18502 record, unconditionally call Missing_Read_Write_Attributes recursively
18503 (remove guard checking for Is_Record_Type / Is_Access_Type).
18505 2006-10-31 Robert Dewar <dewar@adacore.com>
18507 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18508 useless assignments here and conditionalize it on absence of exception
18510 (Analyze_Exception_Handlers): Small code reorganization of error
18511 detection code, for new handling of formal packages.
18513 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18514 Hristian Kirtchev <kirtchev@adacore.com>
18516 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18517 that has been constant-folded, preserve information of original tree,
18519 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18520 generated private extension declaration if the formal derived type is
18521 synchronized. Carry synchronized present over to the generated private
18523 (Validate_Derived_Type_Instance): Ensure that the actual of a
18524 synchronized formal derived type is a synchronized tagged type.
18525 (Instantiate_Formal_Package): When creating the instantiation used to
18526 validate the actual package of a formal declared without a box, check
18527 whether the formal itself depends on a prior actual.
18528 (Instantiate_Formal_Subprogram): Create new entities for the defining
18529 identifiers of the formals in the renaming declaration, for ASIS use.
18530 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18531 a renaming declaration or a subtype declaration for an actual in an
18532 instance, capture location information of declaration in generic, for
18534 (Instantiate_Formal_Package): Add comments on needed additional tests.
18535 AI-317 (partial parametrization) is fully implemented.
18536 (Validate_Private_Type_Instance): Add check for actual which
18537 must have preelaborable initialization
18538 Use new // insertion for some continuation messages
18539 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18540 Default_Expression. Add type retrieval when the declaration has an
18541 access definition. Update premature usage of incomplete type check.
18542 (Check_Access_Definition): New subsidiary routine. Check whether the
18543 current compilation version is Ada 05 and the supplied node has an
18545 (Instantiate object): Alphabetize local variables. Handle the creation
18546 of new renaming declarations with respect to the kind of definition
18547 used - either an access definition or a subtype mark. Guard against
18548 unnecessary error message in the context of anonymous access types after
18549 they have been resolved. Add check for required null exclusion in a
18550 formal object declaration.
18551 (Switch_View): A private subtype of a non-private type needs to be
18552 switched (the base type can have been switched without its private
18553 dependents because of the last branch of Check_Private_View.
18554 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18556 (Instantiate_Type): Emit an error message whenever a class-wide type of
18557 a tagged incomplete type is used as a generic actual.
18558 (Find_Actual_Type): Extend routine to handle a component type in a child
18559 unit that is imported from a formal package in a parent.
18560 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18561 agree on constrainedness, rather than checking against ultimate ancestor
18562 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18563 generic body, for navigation purposes.
18565 2006-10-31 Robert Dewar <dewar@adacore.com>
18566 Thomas Quinot <quinot@adacore.com>
18568 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18570 (New_Stream_Subprogram): When processing an attribute definition clause
18571 for a stream-oriented subprogram, record an entity node occurring at
18572 the point of clause to use for checking the visibility of the clause,
18573 as defined by 8.3(23) as amended by AI-195.
18574 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18575 New_Stream_Function and New_Stream_Procedure.
18576 (New_Stream_Function, New_Stream_Procedure): Removed.
18577 (Analyze_Attribute_Definition_Clause, case Address): Check new
18578 Alignment_Check check

18581 Javier Miranda <miranda@adacore.com>
18582 Robert Dewar <dewar@adacore.com>
18584 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18585 generate the same errors compiling under -gnatc.
18586 (Try_Object_Operation): If no candidate interpretation succeeds, but
18587 there is at least one primitive operation with the right name, report
18588 error in call rather than on a malformed selected component.
18589 (Analyze_Selected_Component): If the prefix is an incomplete type from
18590 a limited view, and the full view is available, use the full view to
18591 determine whether this is a prefixed call to a primitive operation.
18592 (Operator_Check): Verify that a candidate interpretation is a binary
18593 operation before checking the type of its second formal.
18594 (Analyze_Call): Add additional warnings for function call contexts not
18596 (Analyze_Allocator): Move the check for "initialization not allowed for
18597 limited types" after analyzing the expression. This is necessary,
18598 because OK_For_Limited_Init looks at the structure of the expression.
18599 Before analysis, we don't necessarily know what sort of expression it
18600 is. For example, we don't know whether F(X) is a function call or an
18601 indexed component; the former is legal in Ada 2005; the latter is not.
18602 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18603 were missing. We also didn't handle qualified expressions. Now also
18604 allow function calls. Use new common routine OK_For_Limited_Init.
18605 (Analyze_Type_Conversion): Do not perform some legality checks in an
18606 instance, because the error message will be redundant or spurious.
18607 (Analyze_Overloaded_Selected_Component): Do not do style check when
18608 setting an entity, since we do not know it is the right entity yet.
18609 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18610 (Analyze_Overloaded_Selected_Component): Same change
18611 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18612 since regular incomplete subtypes are transformed into corresponding
18613 subtypes of their full views.
18614 (Complete_Object_Operation): Treat name of transformed subprogram call
18615 as coming from source, for browsing purposes.
18616 (Try_Primitive_Operation): If formal is an access parameter, compare
18617 with base type of object to determine whether it is a primitive
18619 (Operator_Check): If no interpretation of the operator matches, check
18620 whether a use clause on any candidate might make the operation legal.
18621 (Try_Class_Wide_Operation): Check whether the first parameter is an
18622 access type whose designated type is class-wide.

18629 warn on infinite loops.
18630 Add \\ to some continuation messages
18631 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18632 (Process_Bounds): If the bounds are integer literals that result from
18633 constant-folding, and they carry a user-defined type, preserve that type
18634 rather than treating this as an integer range.
18635 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18636 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18637 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18638 left hand side of assignment.
18639 (Analyze_Assignment): Add suport to manage assigments to the attribute
18640 priority of a protected object.
18641 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18642 not just identifiers.
18643 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18644 or AND THEN for possible tracking.
18645 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18646 case of while loops so we can track values in the loop body.

18649 Hristian Kirtchev <kirtchev@adacore.com>
18650 Bob Duff <duff@adacore.com>
18652 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18653 procedure cannot be a protected operation (it is a basic_declaration,
18654 not a subprogram_declaration).
18655 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18656 Subp. Add logic for entry processing.
18657 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18658 Determine whether an entry or subprogram of a protected or task type
18659 override an inherited primitive of an implemented interface.
18660 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18661 Update the actual used in calls to Check_Overriding_Indicator.
18662 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18663 generate the proper reference to the parent unit, for cross-reference.
18664 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18666 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18667 (Add_Extra_Formal): Revise procedure to allow passing in associated
18668 entity, scope, and name suffix, and handle setting of the new
18669 Extra_Formals field.
18670 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18671 pass new parameters. Add support for adding the new extra access formal
18672 for functions whose calls are treated as build-in-place.
18673 (Analyze_A_Return_Statement): Correct casing in error message.
18674 Move Pop_Scope to after Analyze_Function_Return, because an extended
18675 return statement really is a full-fledged scope. Otherwise, visibility
18676 doesn't work right. Correct use of "\" for continuation messages.
18677 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18678 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18679 the node doesn't get properly marked as analyzed.
18680 (Analyze_Subprogram_Body): If subprogram is a function that returns
18681 an anonymous access type that denotes a task, build a Master Entity
18683 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18684 proper usage of null exclusion in a result definition.
18685 (Process_Formals): Code cleanup and new error message.
18686 (Process_Formals): Detect incorrect application of null exclusion to
18688 (Conforming_Types): Handle conformance between [sub]types and itypes
18689 generated for entities that have null exclusions applied to them.
18690 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18691 base type is an access subtype. This case arrises with null exclusions.
18692 (New_Overloaded_Entity): Do not remove the overriden entity from the
18693 homonym chain if it corresponds with an abstract interface primitive.
18694 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18695 call to the synthesized predicate Is_Incomplete_Type.
18696 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18698 (Analyze_Subprogram_Declaration): Check that abstract interface
18699 primitives are abstract or null.
18700 (Analyze_Subprogram_Specification): Remove previous check for abstract
18701 interfaces because it was not complete.
18702 (Has_Interface_Formals): Removed.
18704 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18705 Javier Miranda <miranda@adacore.com>
18707 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18708 of Analyze_Package_Body, to create Itype references for anonymous
18709 access types created in the package declaration, whose designated types
18710 may have only a limited view.
18711 (Analyze_Package_Specification): For the private part of a nested
18712 package, install private_with_clauses of enclosing compilation unit if
18713 we are in its visible part.
18714 (Declare_Inherited_Private_Subprograms): Complete barrier
18715 to ensure that the primitive operation has an alias to some parent
18716 primitive. This is now required because, after the changes done for the
18717 implementation of abstract interfaces, the contents of the list of
18718 primitives has entities whose alias attribute references entities of
18719 such list of primitives.
18720 (Analyze_Package_Specification): Simplify code that handles parent units
18721 of instances and formal packages.
18722 (Uninstall_Declarations): Check the convention consistency among
18723 primitive overriding operations of a tagged record type.

18734 (Analyze_Generic_Renaming): Same fix
18735 (Use_One_Package): Do not take into account the internal entities of
18736 abstract interfaces during the analysis of entities that are marked
18737 as potentially use-visible.
18738 (Find_Type): Handle the case of an attribute reference for
18739 implementation defined attribute Stub_Type (simply let the analysis of
18740 the attribute reference rewrite it).
18741 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18742 type that appears in a Use_Type clause.
18743 (Analyze_Object_Renaming): Add support for renaming of the Priority
18745 (Find_Type): In Ada 2005, a task type can be used within its own body,
18746 when it appears in an access definition.
18747 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18748 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18749 in a formal object declaration or in a subtype declaration.
18750 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18751 (Check_Null_Exclusion): New local routine to
18752 Analyze_Subprogram_Renaming. Check whether the formals and return
18753 profile of a renamed subprogram have required null exclusions when
18754 their counterparts of the renaming already impose them.
18755 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18756 Determine whether an entity is inside a generic scope.
18757 (In_Open_Scope): First pass of documentation update.
18758 (Find_Expanded_Name): Add support for shadow entities associated with
18759 limited withed packages. This is required to handle nested packages.
18760 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18761 that makes a renaming of a limited withed package illegal.

18767 Check_Overriding_Indicator.
18768 (Analyze_Task_Definition): Ditto.
18769 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18770 (Check_Overriding_Indicator): To find overridden interface operation,
18771 examine only homonyms that have an explicit subprogram declaration, not
18772 inherited operations created by an unrelated type derivation.
18773 (Check_Overriding_Indicator): When checking for the presence of "null"
18774 in a procedure, ensure that the queried node is a procedure
18776 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18777 type when the formal is an access to variable.
18778 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18779 (Analyze_Task_Type): Same addition
18780 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to

18788 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18789 inherited from an interface ancestor by another interface in the
18790 context of an instance as 'late'.
18791 (Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
18792 of a call to a function that dispatches on access result.
18793 (Check_Dispatching_Operation): In case of late overriding of a primitive
18794 that covers abstract interface subprograms we register it in all the
18795 secondary dispatch tables associated with abstract interfaces.
18796 (Check_Dispatching_Call): Add check that a dispatching call is not made
18797 to a function with a controlling result of a limited type. This is a
18798 current implementation restriction.
18799 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18800 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18801 argument is an interface type that is a generic formal.
18802 (Is_Interface_Subprogram): Removed.
18803 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18804 operation, check the formals to handle the case in which it is
18805 associated with an abstract interface type.

19618 * sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
19619 abstract interface type, the static analysis is not enough to know if
19620 the interface is implemented or not by the source tagged type. Hence
19621 we must pass the work to the expander to generate the required code to
19622 evaluate the conversion at run-time.
19623 (Resolve_Equality_Op): Do not apply previous
19624 transformation if expansion is disasbled, to prevent anomalies when

20285 * switch.ads, switch.adb (Bad_Switch): New procedure
20287 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20288 Remove 0-9 as debug flag character possibilities
20289 -d is now controlling the primary stack size when its value is a
20290 positive. Also add checks against invalid values, and support for kb,
20291 mb. Ditto for -D switch.
20293 2006-02-13 Robert Dewar <dewar@adacore.com>
20294 Serguei Rybin <rybin@adacore.com>
20296 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20297 save/restore routines.
20298 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20299 were not always properly handled previously.
20300 Since we are changing the tree format anyway, also get rid of the
20301 junk obsolete Immediate_Errors flag.
20302 (Tree_Read): Change the way of reading Tree_Version_String - now we
20303 read the version string from the tree even if its length is not the
20304 same as the length of the version string computed from Gnatvsn.
20305 (Search_Directory_Present): New Boolean flag for the compiler.
20306 Define Tree_Version_String as a dynamic string.
20307 (Default_Stack_Size): new variable, used to handle switch -d.
20310 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
20311 only for main unit.
20312 Add pragma Ada_2005 (synonym for Ada_05)
20313 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20314 were not always properly handled previously.
20316 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
20317 explicit Ada_95 to Ada_2005.
20319 2006-02-13 Javier Miranda <miranda@adacore.com>
20320 Robert Dewar <dewar@adacore.com>
20321 Ed Schonberg <schonberg@adacore.com>
20323 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20324 against errors in the source program: a private types for which the
20325 corresponding full type declaration is missing and pragma CPP_Virtual
20327 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20328 (Is_Known_Null): New flag
20329 (Has_Pragma_Pure): New flag

20331 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20332 explicitly declared limited.
20333 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20334 entities. Only used for component marked Is_Tag. If present it stores
20335 the Offset_To_Top function used to provide this value in tagged types
20336 whose ancestor has discriminants.
20338 * exp_ch2.adb: Update status of new Is_Known_Null flag
20340 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20342 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20343 the categorization sense if Is_Pure was set by pragma Pure_Function.
20345 2006-02-13 Quentin Ochem <ochem@adacore.com>
20346 Olivier Hainque <hainque@adacore.com>
20348 * bindusg.adb: Updated documentation for -d and -D switches.
20350 * raise.h (__gnat_set_globals): added new parameter for
20351 Default_Stack_Size.
20353 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20354 (__gnat_handle_vms_condition): Adjust context before raise.
20355 (__gnat_install_handler): Restore the global vector setup for GCC
20356 versions before 3.4, as the frame based circtuitry is not available
20358 (__gnat_set_globals): added a parameter default_stack_size
20359 (__gl_default_stack_size): new variable.
20361 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20363 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20364 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20365 does not exist in the Ada RM.
20366 (Compatible_Int_Bounds): Determine whether two integer range bounds
20367 are of equal length and have the same start and end values.
20368 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20369 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20370 aggregate when it is part of an object declaration.
20371 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20372 constrains discriminants of its parent, add explicitly the discriminant
20373 constraints of the ancestor by retrieving them from the
20374 stored_constraint of the parent.
20376 2006-02-13 Robert Dewar <dewar@adacore.com>
20378 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20379 attribute Mechanism_Code is applied to renamed subprogram, modify
20380 prefix to point to base subprogram.
20381 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20383 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20384 renamed subprograms so that the front-end must replace the prefix
20387 2006-02-13 Javier Miranda <miranda@adacore.com>
20388 Gary Dismukes <dismukes@adacore.com>
20390 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20391 availability of RE_Interface_Tag.
20392 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20393 (Freeze_Record_Type): Do not generate the tables associated with
20394 timed and conditional dispatching calls through synchronized
20395 interfaces if compiling under No_Dispatching_Calls restriction.
20396 When compiling for Ada 2005, for a nonabstract
20397 type with a null extension, call Make_Controlling_Function_Wrappers
20398 and insert the wrapper function declarations and bodies (the latter
20399 being appended as freeze actions).
20400 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20401 predefined primitives associated with timed and conditional
20402 dispatching calls through synchronized interfaces if we are
20403 compiling under No_Dispatching_Calls.
20404 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20405 service is available before generating a call.
20406 (Make_Controlling_Function_Wrappers): New procedure.
20407 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20408 access-to-limited-interfaces because they can be used to reference
20409 tasks that implement such limited interface.
20410 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20411 procedure spec and body of the Offset_To_Top function that is generated
20412 when the parent of a type with discriminants has secondary dispatch
20414 (Init_Secondary_Tags): Handle the case in which the parent of the type
20415 containing secondary dispatch tables has discriminants to generate the
20416 correct arguments to call Set_Offset_To_Top.
20417 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20419 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20420 Add Wide_[Wide_]Expanded_Name.
20421 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20422 the same functionality of Get_Prim_Op_Address but applied to predefined
20423 primitive operations because the pointers to the predefined primitives
20424 are now saved in a separate table.
20425 (Parent_Size): Modified to get access to the separate table of primitive
20426 operations or the parent type.
20427 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20428 functionality of Set_Prim_Op_Address but applied to predefined primitive
20430 (Set_Signature): New subprogram used to store the signature of a DT.
20431 (Displace): If the Offset_To_Top value is not static then call the
20432 function generated by the expander to get such value; otherwise use
20433 the value stored in the table of interfaces.
20434 (Offset_To_Top): The type of the actual has been changed to Address to
20435 give the correct support to tagged types with discriminants. In this
20436 case this value is stored just immediately after the tag field.
20437 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20438 offset_to_top value is static and hence pass this value to the run-time
20439 to store it in the table of interfaces, or else if this value is dynamic
20440 and then pass to the run-time the address of a function that is
20441 generated by the expander to provide this value for each object of the
20444 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20445 (Default_Prim_Op_Count): New entity
20446 (Get_Predefined_Prim_Op_Address): New entity
20447 (Set_Predefined_Prim_Op_Address): New entity

20451 Ed Schonberg <schonberg@adacore.com>
20453 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20454 Make_Adjust_Call done for a newly-allocated object.
20456 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20457 in a subprogram are wrapped in a cleanup block, indicate that the
20458 subprogram contains an inner block with an exception handler.
20459 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20460 Adjust call is for a newly-allocated object. In that case we must not
20461 assume that the finalization list chain pointers are correct (since they
20462 come from a bit-for-bit copy of the original object's pointers) so if
20463 the attach level would otherwise be zero (no change), we set it to 4
20464 instead to cause the pointers to be reset to null.
20466 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20467 reset chain pointers to null.
20469 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20471 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20472 string, and the context requires a loop for the assignment (e.g.
20473 because the left-hand side is packed), generate a unique name for the
20474 temporary that holds the string, to prevent spurious name clashes.
20476 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20477 Javier Miranda <miranda@adacore.com>
20478 Robert Dewar <dewar@adacore.com>
20479 Gary Dismukes <dismukes@adacore.com>
20481 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20482 return unconstrained arrays.
20484 (Expand_Call): An indirect call through an access parameter of a
20485 protected operation is not a protected call.
20486 Add circuit to raise CE in Ada 2005 mode following call
20487 to Raise_Exception.
20488 (Register_DT_Entry): Do nothing if
20489 the run-time does not give support to abstract interfaces.
20490 (Freeze_Subprogram): In case of dispatching operations, do not generate
20491 code to register the operation in the dispatch table if the source
20492 is compiled with No_Dispatching_Calls.
20493 (Register_Predefined_DT_Entry): Generate code that calls the new
20494 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20495 Set_Prim_Op_Address.
20497 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20498 on array assignments if the right-hand side is a function call that has
20499 been inlined. Check is performed on the assignment in the block.
20500 (Process_Bounds): If bounds and range are overloaded, apply preference
20501 rule for root operations to disambiguate, and diagnose true ambiguity.
20502 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20503 a tag-indeterminate right-hand side even when Expander_Active is True.
20504 Needed to ensure that dispatching calls to T'Input are allowed and
20505 get the tag of the target class-wide object.
20507 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20508 an inherited primitive operation that already overrides several
20509 abstract interface primitives. For transitivity, the new entity must
20510 also override all the abstract interface primitives covered by the
20511 inherited overriden primitive.
20512 Emit warning if new entity differs from homograph in same scope only in
20513 that one has an access parameter and the other one has a parameter of
20514 a general access type with the same designated type, at the same
20515 position in the signature.
20516 (Make_Inequality_Operator): Use source locations of parameters and
20517 subtype marks from corresponding equality operator when creating the
20518 tree structure for the implicit declaration of "/=". This does not
20519 change anything in behaviour except that the decoration of the
20520 components of the subtree created for "/=" allows ASIS to get the
20521 string images of the corresponding identifiers.
20522 (Analyze_Return_Statement): Remove '!' in warning message.
20523 (Check_Statement_Sequence): Likewise.
20524 (Analyze_Subprogram_Body): For an access parameter whose designated type
20525 is an incomplete type imported through a limited_with clause, use the
20526 type of the corresponding formal in the body.
20527 (Check_Returns): Implicit return in No_Return procedure now raises
20528 Program_Error with a compile time warning, instead of beging illegal.
20529 (Has_Single_Return): Function returning unconstrained type cannot be
20530 inlined if expression in unique return statement is not an identifier.
20531 (Build_Body_To_Inline): It is possible to inline a function call that
20532 returns an unconstrained type if all return statements in the function
20533 return the same local variable. Subsidiary procedure Has_Single_Return
20534 verifies that the body conforms to this restriction.
20536 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20537 same type, and one of them is of an anonymous access type, convert
20538 the other operand to it, so that this is a valid binary operation for
20540 (Resolve_Type_Conversion): Handle subtypes of protected types and
20541 task types when accessing to the corresponding record type.
20542 (Resolve_Allocator): Add '\' in 2-line warning message.
20543 Remove '!' in warning message.
20544 (Resolve_Call): Add '\' in 2-line warning message.
20545 (Valid_Conversion): Likewise.
20546 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20547 resulting type may be an access type with an implicit dereference.
20548 Obtain the proper component from the designated type.
20549 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20550 given by an expanded name with prefix Standard, when the operands are
20551 of an anonymous access type.
20552 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20553 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20554 prefix of the expression is not of an incomplete type. Allows full
20555 diagnoses of all semantic errors.
20556 (Resolve_Actuals): If the actual is an allocator whose directly
20557 designated type is a class-wide interface we build an anonymous
20558 access type to use it as the type of the allocator. Later, when
20559 the subprogram call is expanded, if the interface has a secondary
20560 dispatch table the expander will add a type conversion to force
20561 the displacement of the pointer.
20562 (Resolve_Call): If a function that returns an unconstrained type is
20563 marked Inlined_Always and inlined, the call will be inlined and does
20564 not require the creation of a transient scope.
20565 (Check_Direct_Boolean_Op): Removed
20566 (Resolve_Comparison_Op): Remove call to above
20567 (Resolve_Equality_Op): Remove call to above
20568 (Resolve_Logical_Op): Inline above, since this is only call.
20569 (Valid_Conversion): Handle properly conversions between arrays of
20570 convertible anonymous access types.
20573 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20574 the literal in an unchecked conversion, because GCC 4.x needs a static
20575 value for a string bound.
20577 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20578 Hristian Kirtchev <kirtchev@adacore.com>
20580 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20581 components of the corresponding record, take into account component
20582 definitions that are access definitions.
20583 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20584 procedure is not considered a dispatching call and will be expanded
20587 2006-02-13 Javier Miranda <miranda@adacore.com>
20589 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20590 controlling argument of the dispatching call is an abstract interface
20591 class-wide type then we use it directly.
20592 Check No_Dispatching_Calls restriction.
20593 (Default_Prim_Op_Position): Remove the code that looks for the last
20594 entity in the list of aliased subprograms. This code was wrong in
20596 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20597 when the source is compiled with the No_Dispatching_Calls restriction.
20598 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20599 if we are compiling with restriction No_Dispatching_Calls.
20600 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20601 subprograms if we are compiling under No_Dispatching_Calls restriction.
20602 (Make_DT): Generate a dispatch table with a single dummy entry if
20603 we are compiling with the No_Dispatching_Calls restriction. In
20604 addition, in this case we don't generate code that calls to the
20605 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20606 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20607 of this subprogram if compiling with the No_Dispatching_Calls
20609 (Expand_Type_Conversion): Instead of using the actual parameter,
20610 the argument passed as parameter to the conversion function was
20611 erroneously referenced by the expander.
20612 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20613 Set_Predefined_Primitive_Op_Address and Set_Signature.
20614 (Expand_Dispatching_Call): Generate call to
20615 Get_Predefined_Prim_Op_Address for predefined primitives.
20616 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20617 predefined primitives.
20618 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20619 primitives we reserve one dummy entry to ensure that the tag does not
20620 point to some memory that is associated with some other object. In
20621 addition, remove all the old code that generated the assignments
20622 associated with the signature of the dispatch table and replace them
20623 by a call to the new subprogram Set_Signature.
20624 (Set_All_DT_Position): Change the algorithm because now we have a
20625 separate dispatch table associated with predefined primitive operations.
20626 (Expand_Interface_Conversion): In case of non-static offset_to_top
20627 add explicit dereference to get access to the object after the call
20628 to displace the pointer to the object.
20629 (Expand_Interface_Thunk): Modify the generation of the actual used
20630 in the calls to the run-time function Offset_To_Top to fulfil its
20632 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20634 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20636 * exp_dist.adb (Copy_Specification): For access parameters, copy
20637 Null_Exclusion flag, which will have been set for stream subprograms
20640 2006-02-13 Pascal Obry <obry@adacore.com>
20642 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20643 previous implementation was using the C runtime spawnve routine but
20644 the corresponding wait was using directly the Win32 API. This was
20645 causing some times a lock when waiting for an event using
20646 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20647 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20648 API fixes this problem.
20650 2006-02-13 Robert Dewar <dewar@adacore.com>
20652 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze
20655 2006-02-13 Thomas Quinot <quinot@adacore.com>
20657 * exp_pakd.ads: Fix typos in comments.
20659 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20660 array reference that is an explicit dereference, mark the converted
20661 (packed) array reference as analyzed to prevent a forthcoming
20662 reanalysis from resetting its type to the original (non-packed) array
20665 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20666 Javier Miranda <miranda@adacore.com>
20667 Eric Botcazou <ebotcazou@adacore.com>
20669 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20670 Is_Predefined_Primitive_Operation): When
20671 searching for the predefined equality operator, verify that operands
20672 have the same type.
20673 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20674 for the last entity in the list of aliased subprograms. This code
20675 was wrong in case of renamings.
20676 (Set_Renamed_Subprogram): New procedure
20677 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20678 Exp_Type constant computed when entering this subprogram.
20679 (Known_Null): New function
20680 (OK_To_Do_Constant_Replacement): New function
20681 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20682 (Side_Effect_Free): An attribute reference 'Input is not free of
20683 side effect, unlike other attributes that are functions. (from code
20685 (Remove_Side_Effects): Expressions that involve packed arrays or records
20686 are copied at the point of reference, and therefore must be marked as
20687 renamings of objects.
20688 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20689 not a dispatching operation.
20692 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20693 elementary types in all cases.
20695 2006-02-13 Javier Miranda <miranda@adacore.com>
20697 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20698 task types when accessing to the corresponding record type.
20699 Remove '!' in warning message.
20701 2006-02-13 Olivier Hainque <hainque@adacore.com>
20703 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20704 to avoid useless and space inefficient overalignments on targets where
20705 Max_Alignment is larger than 16.
20707 2006-02-13 Pascal Obry <obry@adacore.com>
20709 * g-catiio.adb (Sec_Number): New type used to compute the number of
20710 seconds since 1-1-1970.
20711 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20712 negative numbers (years, months...) it is better to have a Natural here.
20714 (Image) [Number]: Change parameter from Long_Integer to Number.
20715 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20716 overflow for dates past year 2038.
20718 2006-02-13 Matthew Heaney <heaney@adacore.com>
20720 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20723 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20725 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20727 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that

20735 Rules_Switches table. Append these -rules switches after the -cargs
20738 2006-02-13 Robert Dewar <dewar@adacore.com>
20740 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20741 These two cases were generating incorrect output, and if this unit
20742 was built with checks on, generated a discriminant mismatch constraint
20745 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20746 Robert Dewar <dewar@adacore.com>
20748 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20749 view is an array type, indicate the component type as well, for
20750 navigation purposes.
20751 (Generate_Reference): Don't consider array ref on LHS to be a case
20752 of violating pragma Unreferenced.
20753 Do not give Ada 2005 warning except on real reference.
20755 2006-02-13 Vincent Celier <celier@adacore.com>
20757 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20758 main source, add switch -mdebug-main=_ada_ so that the executable can
20759 be debugged by the standard VMS debugger.
20760 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20761 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20762 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20763 of the last source, as the binding and linking phases are never
20765 Set all executable obsolete when rebuilding a library.
20767 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20770 2006-02-13 Javier Miranda <miranda@adacore.com>
20773 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20774 code to improve the error message reported when the program has
20775 declarations of abstract interface types and it is not compiled with
20776 the -gnat05 switch.
20777 (P_Access_Definition): Reorganize the code to improve the error
20778 message reported when the new Ada 2005 syntax for anonymous
20779 access types is used and the program is not compiled with the

20802 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20803 unknown, use the location of the project to report the error.
20804 (When_No_Sources): New global variable
20805 (Report_No_Ada_Sources): New procedure
20806 (Check): New parameter When_No_Sources. Set value of global variable

20809 (Get_Sources_From_File): Ditto
20810 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20813 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20814 Call Prj.Proc.Process with parameter When_No_Sources.
20816 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20817 Call Recursive_Check with parameter When_No_Sources.
20818 (Recursive_Check): New parameter When_No_Sources. Call itself and
20819 Prj.Nmsc.Check with parameter When_No_Sources.
20820 (Process): New parameter When_No_Sources. Call Check with parameter
20822 (Copy_Package_Declarations): New procedure to copy renamed parameters
20823 and setting the location of the declared attributes to the location

20830 * prj-makr.adb (Make): Preserve the comments from the original project
20832 When removing nodes (attributes Source_Dirs, Source_Files,
20833 Source_List_File and package Naming), save the comments and attach the
20834 saved comments to the newly created nodes.
20835 Do not add a with clause for the naming package if one already exists.

20843 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
20844 aliased entities to look for the overriden abstract interface
20846 (Is_Interface_Subprogram): Complete documentation.
20847 (Check_Dispatching_Operation): Do not generate code to register the
20848 operation in the dispatch table if the source is compiled with
20849 restriction No_Dispatching_Calls.

20851 No_Return procedure with procedure that is not No_Return
20852 (Check_Dispatching_Call): Suppress the check for an abstract operation
20853 when the original node of an actual is a tag-indeterminate attribute
20854 call, since the attribute, which must be 'Input, can never be abstract.
20855 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20856 call to the Input attribute (even when rewritten).
20857 (Propagate_Tag): Augment comment to indicate the possibility of a call
20858 to an Input attribute.
20860 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
20861 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
20863 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.

20870 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20872 2006-02-13 Javier Miranda <miranda@adacore.com>
20874 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20875 handles default-initialized components to keep separate the management
20876 of this feature but also avoid the unrequired resolution and
20877 expansion of components that do not have partially initialized
20879 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20880 (Check_Bounds): Likewise.
20881 (Check_Length): Likewise.
20883 2006-02-13 Javier Miranda <miranda@adacore.com>
20884 Ed Schonberg <schonberg@adacore.com>
20886 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20887 abstract interface type call analyze_and_resolve to expand the type
20888 conversion into the corresponding displacement of the
20889 reference to the base of the object.
20890 (Eval_Attribute, case Width): For systems where IEEE extended precision
20891 is supported, the maximum exponent occupies 4 decimal digits.
20892 (Accessibility_Message): Add '\' in 2-line warning message.
20893 (Resolve_Attribute): Likewise.
20894 (case Attribute_Access): Significantly revise checks
20895 for illegal access-to-subprogram Access attributes to properly enforce
20896 the rules of 3.10.2(32/2).
20897 Diagnose use of current instance with an illegal attribute.
20899 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20901 (Enclosing_Generic_Unit): New function to return a node's innermost
20902 enclosing generic declaration node.
20903 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20904 (Type_Access_Level): The accessibility level of anonymous acccess types
20905 associated with discriminants is that of the current instance of the
20906 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20907 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20908 (Kill_Current_Values_For_Entity): New function
20909 (Enter_Name): Change formal type to Entity_Id
20911 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
20912 Ed Schonberg <schonberg@adacore.com>
20913 Gary Dismukes <dismukes@adacore.com>
20915 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20916 Analyze_Compilation_Unit.
20917 Detect and warn on redundant with clauses detected in a package spec
20918 and/or body when -gnatwr is used.
20919 (Analyze_Context): Analyze config pragmas before other items
20920 (Install_Context_Items): Don't analyze config pragmas here
20921 (Install_Limited_Withed_Unit): Set limited entity of package in
20922 with_clause so that cross-reference information or warning messages on
20923 unused packages can be properly generated
20924 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20925 has Error_Posted set. Prevent infinite loops in illegal programs.
20926 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20927 to the point of the error test requiring the current unit to be private.
20928 This ensures that private with clauses are not exempted from the basic
20929 checking for being a descendant of the same library unit parent as a
20930 withed private descendant unit.
20931 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20932 handle private with clauses properly, as well as to account for cases
20933 where the withed unit is a public descendant of a private ancestor
20934 (in which case the current unit must be a descendant of the private
20935 ancestor's parent). The spec comments were updated accordingly. Also,
20936 the old error message in this subprogram was replaced with error
20937 messages that mirror the errors tested and reported by
20938 Check_Private_Child_Unit.
20939 Parameter and variable names improved for readability.
20940 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20941 private as the precondition for calling
20942 Check_Private_Limited_Withed_Unit since that subprogram has been
20943 revised to test public units as well as private units.

20948 Javier Miranda <miranda@adacore.com>
20950 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20951 that Scope_Stack.First = 1.
20952 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20953 were not always properly handled previously.
20954 (Formal_Entity): Complete rewrite, to handle properly some complex case
20955 with multiple levels of parametrization by formal packages.
20956 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20957 to the corresponding derived type declaration for proper semantics.
20959 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20960 (Check_Component): Enforce restriction on components of
20961 unchecked_unions: a component in a variant cannot contain tasks or
20963 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20965 Add pragma Ada_2005 (synonym for Ada_05)
20966 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20967 were not always properly handled previously.
20968 Document that pragma Propagate_Exceptions has no effect
20969 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20970 (Set_Convention_From_Pragma): Check that if a convention is
20971 specified for a dispatching operation, then it must be
20972 consistent with the existing convention for the operation.
20973 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20974 longer required to specify an vtable-ptr component in the record. For
20975 compatibility reasons we leave the support for the previous definition.
20976 (Analyze_Pragma, case No_Return): Allow multiple arguments
20978 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20979 non-overrideen inherited operation with a controlling result as
20980 illegal only its implicit declaration comes from the derived type
20981 declaration of its result's type.
20982 (Check_Possible_Deferred_Completion): Relocate the object definition
20983 node of the subtype indication of a deferred constant completion rather
20984 than directly analyzing it. The analysis of the generated subtype will
20985 correctly decorate the GNAT tree.
20986 (Record_Type_Declaration): Check whether this is a declaration for a
20987 limited derived record before analyzing components.
20988 (Analyze_Component_Declaration): Diagnose record types not explicitly
20989 declared limited when a component has a limited type.
20990 (Build_Derived_Record_Type): Code reorganization to check if some of
20991 the inherited subprograms of a tagged type cover interface primitives.
20992 This check was missing in case of a full-type associated with a private
20994 (Constant_Redeclaration): Check that the subtypes of the partial and the
20995 full view of a constrained deferred constant statically match.
20996 (Mentions_T): A reference to the current type in an anonymous access
20997 component declaration must be an entity name.
20998 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20999 class_wide type to refer to full type, not to the incomplete one.
21000 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21001 available. Required to give support to the certified run-time.
21002 (Analyze_Component_Declaration): In case of anonymous access components
21003 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21004 (Process_Discriminants): For an access discriminant, use the
21005 discriminant specification as the associated_node_for_itype, to
21006 simplify accessibility checks.
21008 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21009 Javier Miranda <miranda@adacore.com>
21011 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21012 abstract interpretations on an operator, remove interpretations that
21013 yield Address or a type derived from it, if one of the operands is an
21015 (Try_Object_Operation.Try_Primitive_Operation,
21016 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21017 location when creating the new reference to a primitive or class-wide
21018 operation as a part of rewriting a subprogram call.
21019 (Try_Primitive_Operations): If context requires a function, collect all
21020 interpretations after the first match, because there may be primitive
21021 operations of the same type with the same profile and different return
21022 types. From code reading.
21023 (Try_Primitive_Operation): Use the node kind to choose the proper
21024 operation when a function and a procedure have the same parameter
21026 (Complete_Object_Operation): If formal is an access parameter and prefix
21027 is an object, rewrite as an Access reference, to match signature of
21028 primitive operation.
21029 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21030 by an expanded name with prefix Standard, when the operands are of an
21031 anonymous access type.
21032 (Remove_Abstract_Operations): If the operation is abstract because it is
21033 inherited by a user-defined type derived from Address, remove it as
21034 well from the set of candidate interpretations of an overloaded node.
21035 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21038 2006-02-13 Bob Duff <duff@adacore.com>
21040 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21041 redundant use clauses.
21042 In particular, if the scope of two use clauses overlaps, but one is not
21043 entirely included in the other, we should not warn. This can happen
21044 with nested packages.
21045 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21046 reported errors. The bug was reported when the compiler was built
21047 with assertions enabled.
21048 (Find_Type): If the node is a 'Class reference and the prefix is a
21049 synchronized type without a corresponding record, return the type
21052 2006-02-13 Javier Miranda <miranda@adacore.com>
21054 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21055 if this is the full-declaration associated with a private declaration
21056 that implement interfaces, then the private type declaration must be
21058 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21059 as aliased. The use of the 'access attribute is not available for such
21060 object (for this purpose the object should be explicitly marked as
21061 aliased, but being an anonymous type this is not possible).
21063 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21064 Robert Dewar <dewar@adacore.com>
21066 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21067 compilation unit is an elaboration scope.
21068 (Add_Task_Proc): Add '\' in 2-line warning message.
21069 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21071 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21072 Javier Miranda <miranda@adacore.com>
21074 * sem_type.adb (Write_Overloads): Improve display of candidate
21076 (Add_One_Interp): Do not add to the list of interpretations aliased
21077 entities corresponding with an abstract interface type that is an
21078 immediate ancestor of a tagged type; otherwise we have a dummy
21079 conflict between this entity and the aliased entity.
21080 (Disambiguate): The predefined equality on universal_access is not
21081 usable if there is a user-defined equality with the proper signature,
21082 declared in the same declarative part as the designated type.
21083 (Find_Unique_Type): The universal_access equality operator defined under
21084 AI-230 does not cover pool specific access types.
21085 (Covers): If one of the types is a generic actual subtype, check whether
21086 it matches the partial view of the other type.
21088 2006-02-13 Thomas Quinot <quinot@adacore.com>
21090 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21091 line. This is necessary to allow In_Extended_Main_Unit to provide
21092 correct results for itypes while writing out expanded source.
21093 (Close_File): No need to update the source_index_table here since it's
21094 now done for each line.
21096 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21097 Robert Dewar <dewar@adacore.com>
21099 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21100 preserve the source unit where the itype is declared, and prevent a
21102 (Note_Implicit_Run_Time_Call): New procedure
21103 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21106 * sprint.ads: Document use of $ for implicit run time routine call
21108 2006-02-13 Quentin Ochem <ochem@adacore.com>
21110 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21113 2006-02-13 Bob Duff <duff@adacore.com>
21115 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21116 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21117 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21118 raise Constraint_Error.
21120 * s-vallli.adb (Scan_Long_Long_Integer): Call
21121 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21122 do not scan leading blanks and sign twice.
21123 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21124 raise Constraint_Error.
21126 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21127 Scan_Long_Long_Unsigned): Split out most of the processing from
21128 Scan_Long_Long_Unsigned out into
21129 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21130 This prevents scanning leading blanks and sign twice.
21131 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21134 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21135 out most of the processing from Scan_Unsigned out into
21136 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21137 This prevents scanning leading blanks and sign twice.
21139 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21140 use with Modular'Value attribute.
21141 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21341 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21342 link to the version that does nothing. This way the task termination

21344 because of an unhandled exception.
21346 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21347 handler because of an unhandled exception.
21349 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21355 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21356 non-tasking version of the soft link for task termination. We do
21357 nothing since if we are using the non-tasking version it

21360 in charge of finalizing the global list for controlled objects.
21361 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21362 instead for handling run-time termination in a more flexible way.
21363 (Adafinal_NT): This new procedure will take care of finalizing the
21364 global list for controlled objects if needed, but no tasking
21367 * s-tarest.adb (Task_Lock): Do not try to lock again the
21368 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21369 some run-time operations.
21370 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21371 until all nested locks have been released.
21372 (Task_Wrapper): Call the fall-back task termination handler. It

21380 moved to the Common_ATCB record.
21381 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21382 Common_ATCB record.

21384 Common_ATCB record.
21386 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21387 Fall_Back_Handler, and Specific_Handler.

21391 (Termination_Handler): Redefine this type here, alredy defined in
21392 Ada.Task_Termination, for avoiding circular dependencies.
21393 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21394 for storing task termination handlers. In addition,
21395 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21396 Common_ATCB because it is used by both the regular and the restricted
21398 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21399 Common_ATCB because it is used by both the regular and the restricted
21401 (Common_ATCB): Added a dynamic task analyzer field.

21406 tasks but the environment task.
21407 (Finalize_Global_Tasks): Call the task termination procedure for the

21409 using the soft links mechanism.
21410 (Task_Wrapper): added dynamic stack analysis.
21412 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21413 potentially blocking operations has been moved from
21414 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21415 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21416 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21417 this run-time check.
21419 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21420 of task termination procedure.
21421 (Init_Tasking_Soft_Links): Install the task-safe version of the soft

21463 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21464 to the specification because the frontend generates code that uses this
21466 (Set_Interface_Table): Add missing assertion.
21467 Update documentation describing the run-time structure.
21468 (Displace): New subprogram that displaces the pointer to the object
21469 to reference one of its secondary dispatch tables.
21470 (IW_Membership): Modified to use the new table of interfaces.
21471 (Inherit_TSD): Modified to use the new table of interfaces.
21472 (Register_Interface_Tag): Use the additional formal to fill the
21473 contents of the new table of interfaces.
21474 (Set_Interface_Table): New subprogram that stores in the TSD the

21489 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21490 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21491 record component containing the tag of the secondary dispatch table we
21492 have to use the Offset_To_Top run-time function to get this information;
21493 otherwise if the pointer to the base of the object has been displace
21494 we get a wrong value if we use the 'position attribute.
21496 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21497 all the calls to Expand_Interface_Thunk.
21498 (Make_Secondary_DT): Secondary dispatch tables do not have a table of

21501 ensure that the interfaces implemented by the ancestors are placed
21502 at the header of the generated list.
21503 (Expand_Interface_Conversion): Handle the case in which the displacement
21504 associated with the interface conversion is not statically known. In
21505 this case we generate a call to the new run-time subprogram Displace.

21507 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21508 Get_Tagged_Kind and Set_Tagged_Kind.

21532 RE_TK_Tagged, RE_TK_Task.
21534 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21535 Init_Secondary_Tags_Internal to allow its use with interface types and
21536 also to generate the code for the new additional actual required
21537 by Set_Offset_To_Top.
21538 (Build_Init_Statements): In case of components associated with abstract
21539 interface types there is no need to generate a call to its IP.
21540 (Freeze_Record_Type): Generate Select Specific Data tables only for

21550 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21551 properly protected objects and attach handler in the case of the
21552 restricted profile.

21566 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21567 about the use and expansion of SAVE_EXPRs in the various possible
21568 renaming handling cases.
21569 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21570 abusing DECL_FCONTEXT.

21663 the iterator is quitting iteration on parent directory.
21665 2005-12-09 Javier Miranda <miranda@adacore.com>
21667 * exp_ch5.adb (Expand_N_Assignment_Statement): In case of tagged types
21668 and the assignment to a class-wide object, before the assignment we
21669 generate a run-time check to ensure that the tag of the Target is
21670 covered by the tag of the source.

21691 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21692 base type to create anonymous subtype, because entity may be a locally
21693 declared subtype or generic actual.
21694 (Find_Interface): New subprogram that given a tagged type and one of its
21695 component associated with the secondary table of an abstract interface
21696 type, return the entity associated with such abstract interface type.
21698 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21699 conversion cannot be handled at compile time. In this case we pass this
21700 information to the expander to generate the appropriate code.

21735 copied component does not have a known static Esize, then reset
21736 the size and positional fields of the new component.
21737 (Analyze_Component_Declaration): A limited component is
21738 legal within a protected type that implements an interface.
21739 (Collect_Interfaces): Do not add to the list the interfaces that
21740 are implemented by the ancestors.
21741 (Derived_Type_Declaration): If the parent of the full-view is an
21742 interface perform a transformation of the tree to ensure that it has
21743 the same parent than the partial-view. This simplifies the job of the
21744 expander in order to generate the correct object layout, and it is
21745 needed because the list of interfaces of the full-view can be given in
21747 (Process_Full_View): The parent of the full-view does not need to be
21748 a descendant of the parent of the partial view if both parents are
21750 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21751 "limited" the parent must be a limited type.

21765 (Process_Full_View): Improve the check for the "no hidden interface"
21766 rule as defined by AI-396.
21768 2005-12-09 Robert Dewar <dewar@adacore.com>

21825 available user-specified stream attributes on limited parameters to
21826 also test the type directly rather than only its underlying type (for
21827 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21828 attributes are visible at the point of the subprogram declaration.
21829 For Ada 2005, the error message is modified to indicate that the
21830 type's stream attributes must be visible (again, only for -gnat05).

21862 types use the corresponding record type. This was not needed before
21863 the implementation of Ada 2005 synchronized types because
21864 concurrent types were never tagged types in Ada 95.

21992 * socket.c: Add extern int h_errno for rtems since networking header
21993 files are not available at this point in a tool bootstrap. Newlib

21997 Roger Sayle <roger@eyesopen.com>
22000 * misc.c (internal_error_function): Don't use vsprintf to format

22103 deal with different cases of static and dynamic elaboration checks (all
22104 checks does not count in the first case, but does in the second).

22110 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22111 elementary types using the operator in standard. It is cleaner not to
22112 modify the programmers intent, especially in the case of floating-point.
22113 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22114 it did not matter because we always rewrote a/=b to not(a=b).
22115 (Expand_Allocator_Expression): For an allocator expression whose nominal
22116 subtype is an unconstrained packed type, convert the expression to its
22117 actual constrained subtype.
22118 Implement warning for <= or >= where < or > not possible
22119 Fix to Vax_Float tests (too early in many routines, causing premature
22120 Vax_Float expansions.

22126 of pragma Suppress (All_Checks)
22127 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22128 a string literal for precise control over warnings.
22129 Avoid raise of pragma in case of unrecognized pragma and just return
22132 * sem_prag.ads: Minor reformatting
22134 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22135 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter

22137 Include -gnatwx as part of -gnatg (warn on redundant parens)
22138 Allow optional = after -gnatm
22139 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22140 longer sets Elaboration_Checks.
22141 Code to set warning mode moved to Sem_Warn
22142 so that it can be shared by pragma processing.
22144 * s-mastop-tru64.adb (Pop_Frame): Remove redundant parentheses in if
22147 * s-taprop-solaris.adb:
22148 Change some <= to =, to avoid new warning

22156 * exp_vfpt.adb: Handle /= case
22157 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22269 we are not defining the type.
22270 <E_Record_Type>: Likewise.
22271 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22272 to get advantage of the new maybe_stabilize_reference interface, to
22273 ensure that what we reference is indeed stabilized instead of relying
22274 on assumptions on what the stabilizer does.
22275 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22276 type imported through a limited_with clause, use its non-limited view.
22277 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others
22279 (gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
22280 of #if sections + explicit comparisons of convention identifiers.

22282 before early-returning for certain types when code generation is
22284 (gnat_to_gnu_entity) <object>: Adjust comment attached to the
22285 nullification of gnu_expr we do for objects with address clause and
22286 that we are not defining.
22287 (elaborate_expression_1): Do not create constants when creating
22288 variables needed by the debug info: the dwarf2 writer considers that
22289 CONST_DECLs is used only to represent enumeration constants, and emits
22291 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22292 object with an address clause into an indirect reference, drop the
22293 initializing expression.
22295 (STACK_CHECK_BUILTIN): Delete.
22296 (STACK_CHECK_PROBE_INTERVAL): Likewise.

22304 if there is an actual subtype provided by the front-end, use that
22305 subtype to build an actual type with bounds template.
22306 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22307 is provided by the front-end, use that subtype to compute the size of
22308 the deallocated object.

22310 check for a potential violation of a No_Elaboration_Code restriction.

22315 maybe_stabilize, for common uses without restriction on lvalues and
22316 without need to check for the success indication.
22317 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22318 pass false instead of 0 as the FORCE argument which is a bool.
22319 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22320 attached to a renaming pointer has been properly stabilized, as no such
22321 object is attached otherwise.
22322 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22323 function uses the "target pointer" return mechanism.
22324 Reinstate conversion of the actual to the type of the formal
22325 parameter before any other specific treatment based on the passing
22326 mechanism. This turns out to be necessary in order for PLACEHOLDER
22327 substitution to work properly when the latter type is unconstrained.

22331 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22335 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22336 static output of record constructor if all the components are constant.
22337 (gnat_build_constructor): For a record type, sort the list of field
22338 initializers in increasing bit position order.
22339 Factor common code to build a storage type for an unconstrained object
22340 from a fat or thin pointer type and a constrained object type.
22341 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22342 types variants, and process special cases of VIEW_CONVERT expressions
22343 as their NOP_EXPR counterpart to ensure we get to the
22344 CORRESPONDING_VARs associated with CONST_DECls.
22345 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22346 on the right-hand side.
22348 * utils.c (build_unc_object_type_from_ptr): New subprogram, factoring

22353 extracting the object if converting to a type variant.
22354 (create_var_decl): When a variable has an initializer requiring code
22355 generation and we are at the top level, check for a potential violation
22356 of a No_Elaboration_Code restriction.
22357 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22358 SIZE and SIZE_UNIT which we need for later back-annotations.

22361 is an unchecked union.

22363 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22364 main variant, just replace the VIEW_CONVERT_EXPR.

22542 with an actual subtype so GIGI can make a correct size computation.
22543 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22544 'Unrestricted_Access, if the designated type is an interface we
22545 add a type conversion to force the displacement of the pointer
22546 to the secondary dispatch table.
22547 Use Universal_Real instead of Long_Long_Float when we need a high
22548 precision float type for the generated code (prevents gratuitous
22549 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22550 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22551 'Terminated for task interface class-wide objects. Generate a call to
22552 the predefined dispatching routine used to retrieve the _task_id from
22553 a task corresponding record.

22582 the return value into its actual subtype in order to help the backend
22583 to return the actual size instead of the maximum. This is another

22633 attribute of the N_Free_Statement.
22634 Generate itype for classwide designated object in both cases of
22635 user-specified storage pool: specific and class-wide, not only in the
22637 Raise CE when trying to set a not null access type object to null.

22915 leave it more clear.
22916 (Analyze_Type_Declaration): If type has previous incomplete tagged

22973 whose default is abstract because the object type itself is abstract.
22974 (Find_Type): If the type is incomplete and appears as the prefix of a
22975 'Class reference, it is tagged, and its list of primitive operations
22976 must be initialized properly.

23006 statement to inhibit warning.
23007 (Resolve_Unary_Op): Do not produce a warning when
23008 processing an expression of the form -(A mod B)
23009 Use Universal_Real instead of Long_Long_Float when we need a high

23989 Hristian Kirtchev <kirtchev@adacore.com>
23990 Javier Miranda <miranda@adacore.com>
23992 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
23993 from object notation, the original node is unanalyzed and carries no
23994 semantic information, so that accessiblity checks must be performed on
23995 the type of the actual itself.
23996 (Expand_N_Subprogram_Declaration): Change last actual parameter for
23997 compatibility with Build_Protected_Sub_Specification.
23998 (Check_Overriding_Inherited_Interfaces): Add suport to handle

24008 load comes from a Limited_With_Clause.
24010 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24011 whether a potential circularity is harmless, because it includes units
24012 loaded through a limited_with clause. Extends previous treatment which
24013 did not handle properly arbitrary combinations of limited and
24014 non-limited clauses.
24016 2005-09-01 Nicolas Setton <setton@adacore.com>
24018 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types

24048 2005-09-01 Laurent Pautet <pautet@adacore.com>
24050 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24051 position set is provided, we compute one in order to reduce the maximum
24052 length of the keys. This computation first selects a character
24053 position between 1 and the minimum length of the keys in order to
24054 avoid reducing one of the keys to an empty string.
24055 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24056 does not converge. The initialization procedure now comes with a
24057 maximum number of iterations such that when exceeded, an exception is
24058 raised in Compute. The user can initialize this ratio to another value
24060 Reformating and updated headers.
24062 2005-09-01 Javier Miranda <miranda@adacore.com>
24064 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24065 that given an entity T creates and returns an Itype that duplicates the
24066 contents of T. The returned Itype has the null-exclusion
24067 attribute set to True, and its Etype attribute references T
24068 to keep the association between the two entities.
24069 Update copyright notice
24071 * sem_aggr.adb (Check_Can_Never_Be_Null,
24072 Aggregate_Constraint_Checks, Resolve_Aggregate,

24104 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24105 and N_Function_Specification.
24107 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24108 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.

24130 (Write_ALI): For D lines, on platforms where file names are
24131 case-insensitive, record the file names in lower case.
24133 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24134 Emmanuel Briot <briot@adacore.com>

24160 Component_Size attribute specification. Give warning for ignored pragma
24163 * snames.h, snames.ads, snames.adb: Introduce entries in
24164 Preset_Names for Name_Disp_Asynchronous_Select,
24165 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24166 Name_Disp_Timed_Select.
24167 New pragma Debug_Policy
24169 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24171 Switch -gnata also sets Debug_Pragmas_Enabled
24173 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24174 handle an explicit -gnata when compiling predefined files.
24176 2005-09-01 Vincent Celier <celier@adacore.com>
24178 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24179 directories of projects that have no Ada sources.
24181 2005-09-01 Robert Dewar <dewar@adacore.com>
24183 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24184 (makes a difference for wide characters)
24186 * widechar.adb, widechar.ads:
24187 Add Wide_Char_Byte_Count feature to count chars vs bytes
24189 2005-09-01 Thomas Quinot <quinot@adacore.com>
24190 Ed Schonberg <schonberg@adacore.com>
24191 Robert Dewar <dewar@adacore.com>
24193 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24194 'Address attribute reference with an overloaded prefix, use the
24195 location of the prefix (not the location of the attribute reference) as
24196 the error location.
24197 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24198 a function renaming thereof, is a valid prefix for 'Size (where it is
24199 intepreted as a function call).
24200 (Statically_Denotes_Entity): New predicate to determine whether the
24201 prefix of an array attribute can be considered static.
24204 (Eval_Attr): Fix failure to evaluate Component_Size for
24205 unconstrained arrays (resulted in wrong value in packed case, since
24206 back end cannot handle this case)
24208 2005-09-01 Robert Dewar <dewar@adacore.com>
24210 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24211 error msgs for most common cases.

24214 2005-09-01 Javier Miranda <miranda@adacore.com>
24215 Ed Schonberg <schonberg@adacore.com>
24217 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24218 become local to the whole package.
24219 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24220 the package was already analyzed the new algorithm "replaces" the
24221 real entities by the shadow ones. This is required to ensure that
24222 the order of these entities in the homonym chains does not change;
24223 otherwise we can have undefined references at linking time because
24224 in case of conflicts the external name of the entities will have
24225 a suffix that depends on the order of the entities in the chain.
24226 (Remove_Limited_With_Clause): Complementary code that completes the
24227 new algorithm and replaces the shadow entities by the real ones.
24228 (Install_Limited_Withed_Unit): When unchaining entities before the
24229 installation of the shadow entities, only regular entities of the
24230 public part must be taken into account. This is required to
24231 keep this routine in synch with the work done by Remove_Limited_
24233 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24234 even if unit is analyzed, because the analysis of the unit is
24235 idempotent in any case, and the limited view of the unit may have to
24236 be installed for proper visibility.
24237 (Expand_Limited_With_Clause): Even if the unit in the implicit
24238 with_clause has been analyzed already, a limited view of the package
24239 must be built for the current context, if it does not exist yet.

24243 Gary Dismukes <dismukes@adacore.com>
24245 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24246 defining entity for the instance body, make a new defining identifier
24247 rather than copying the entity of the spec, to prevent accidental
24248 sharing of the entity list.
24249 (Check_Private_View): When exchanging views of private types, build the
24250 list of exchanged views as a stack, to ensure that on exit the exchanges
24251 are undone in the proper order.
24252 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24253 Restore the compilation environment in case of instantiation_error.
24254 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24255 for an anonymous access result.
24256 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24257 (Formal_Entity): Handle properly the case of a formal package that
24258 denotes a generic package renaming.
24260 2005-09-01 Thomas Quinot <quinot@adacore.com>
24262 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24263 clause if the array aggregate is surrounded by parentheses.
24265 2005-09-01 Cyrille Comar <comar@adacore.com>
24266 Gary Dismukes <dismukes@adacore.com>
24267 Ed Schonberg <schonberg@adacore.com>
24268 Javier Miranda <miranda@adacore.com>
24270 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24272 to check if a type is Constrained in cases related to code generation
24273 (rather than semantic checking) since otherwise we do not generate
24274 similar code for mutable private types depending if their
24275 discriminants are visible or not.
24276 (Check_Abstract_Overriding): Do not complain about failure to override
24277 the primitive operations used in dispatching selects since they will
24278 always be overriden at the freeze point of the type.
24279 (Access_Definition): Separate out handling for resetting the scope
24280 of an anonymous access function result type. Retrieve the scope
24281 of the associated function rather than using Current_Scope, which
24282 does not have a consistent value (depends on whether we're in the
24283 middle of analyzing formal parameters). Add ??? comment about
24284 finding a cleaner way to handle the special cases of scope setting.
24285 (Process_Incomplete_Dependents): A protected operation is never a
24286 dispatching operation (only its wrapper may be).
24287 (Build_Derived_Record_Type): In case of tagged private types that
24288 implement interfaces add derivation of predefined primitive
24290 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24291 by two parameters that are used in case of derivation from abstract
24292 interface types: No_Predefined_Prims is used to avoid the derivation
24293 of predefined primitives from the interface, and Predefined
24294 Prims_Only is used to complete the derivation predefined primitives
24295 in case of private tagged types implementing interfaces.
24296 Fix typo in comments
24297 (Find_Interface_In_Descendant): Protect the frontend against
24298 wrong code with large circularity chains.
24299 (Is_Private_Overriding): Add support for entities overriding interface
24300 subprograms. The test failed because Entities associated with overriden
24301 interface subprograms are always marked as hidden (and used to build
24302 the secondary dispatch table); in this case the overriden entity is
24303 available through the field abstract_interface_alias (cf. override_
24304 dispatching_operation)
24305 (Access_Definition): Set the scope of the type to Current_Scope for the
24306 case of a function with an anonymous access result type.
24307 (Access_Subprogram_Declaration): Handle creation of the type entity for
24308 an access-to-function type with an anonymous access result.
24309 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24310 in handling for N_Access_Function_Definition.
24311 (Analyze_Subtype_Declaration): Modify the text of error message.
24312 (Derived_Type_Declaration): Modify the text of error message.
24313 (Process_Subtype): Modify the text of error message plus cleanup
24314 of one redundant error message.
24315 (Analyze_Component_Declaration): Code cleanup.
24316 (Analyze_Object_Declaration): Code cleanup.
24317 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24318 attribute in case of access types. Code cleanup.
24319 (Array_Type_Declaration): Code cleanup.
24320 (Process_Discriminants): Create the new null-excluding itype
24321 if required. Code cleanup.
24322 (Process_Subtype): Create the new null-excluding itype if
24323 required. Code cleanup.
24324 (Build_Derived_Record_Type): Code cleanup to avoid calling
24325 twice the subprogram derive_subprograms in case of private
24326 types that implement interfaces. In this particular case the
24327 subprogram Complete_Subprograms_Derivation already does the
24328 job associated with the second call.
24330 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24331 conversion to the full view when generating an operation for a
24332 discriminant whose type may currently be private.
24334 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24335 Javier Miranda <miranda@adacore.com>
24337 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24338 V (Obj.F), the rewriting does not involve the indexed component, but
24339 only the selected component itself.
24340 Do not apply the transformation if the analyzed node is an actual of a
24341 call to another subprogram.
24342 (Complete_Object_Operation): Retain the entity of the
24343 dispatching operation in the selector of the rewritten node. The
24344 entity will be used in the expansion of dispatching selects.
24345 (Analyze_One_Call): Improve location of the error message associated
24347 (Analyze_Selected_Component): No need to resolve prefix when it is a
24348 function call, resolution is done when parent node is resolved, as
24350 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24351 when attempting to resolve a call transformed from its object notation.
24352 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24353 of the argument list for each interpretation of the operation.
24354 (Try_Object_Operation): The designated type of an access parameter may
24355 be an incomplete type obtained through a limited_with clause, in which
24356 case the primitive operations of the type are retrieved from its full
24358 (Analyze_Call): If this is an indirect call, and the return type of the
24359 access_to_subprogram is incomplete, use its full view if available.
24361 2005-09-01 Javier Miranda <miranda@adacore.com>
24362 Gary Dismukes <dismukes@adacore.com>
24364 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24365 access types the null-exclusion and access-to-constant attributes must
24367 (Analyze_Return_Statement): When the result type is an anonymous access
24368 type, apply a conversion of the return expression to the access type
24369 to ensure that appropriate accessibility checks are performed.
24370 (Analyze_Return_Type): For the case of an anonymous access result type,
24371 generate the Itype and set Is_Local_Anonymous_Access on the type.
24372 Add ??? placeholder for check to disallow returning a limited object
24373 in Ada 2005 unless it's an aggregate or a result of a function call.
24374 Change calls from Subtype_Mark to Result_Definition.
24375 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24376 Result_Definition in call to Make_Function_Specification.
24377 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24378 Set_Result_Definition.
24379 (Make_Inequality_Operator): Change formal Subtype_Mark to
24380 Result_Definition in call to Make_Function_Specification.
24381 (Process_Formals): Create the new null-excluding itype if required.
24382 (New_Overloaded_Entity): For an entity overriding an interface primitive
24383 check if the entity also covers other abstract subprograms in the same
24384 scope. This is required to handle the general case, that is, overriding
24385 other interface primitives and overriding abstract subprograms inherited
24386 from some abstract ancestor type.
24387 (New_Overloaded_Entity): For an overriding entity that comes from
24388 source, note the operation that it overrides.
24389 (Check_Conformance, Type_Conformant): Addition of one new formal
24390 to skip controlling formals in the analysis. This is used to
24391 handle overloading of abstract interfaces.
24392 (Base_Types_Match): Add missing case for types imported from
24393 limited-with clauses
24394 (New_Overloaded_Entity): Add barrier to protect the use of
24395 the "alias" attribute.
24397 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24399 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24400 verify that the procedure and the entry are mode conformant.
24401 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24402 as a different operator, which is often a cut-and-paste error.
24404 2005-09-01 Javier Miranda <miranda@adacore.com>
24405 Ed Schonberg <schonberg@adacore.com>
24407 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24408 used in controlling parameters exclude null because it is necessary to
24409 read the tag to dispatch, and null has no tag.
24410 (Override_Dispatching_Operation): If the previous operation is inherited
24411 from an interface, it becomes hidden and does not participate in later
24414 2005-09-01 Javier Miranda <miranda@adacore.com>
24415 Ed Schonberg <schonberg@adacore.com>
24416 Gary Dismukes <dismukes@adacore.com>
24418 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24419 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24420 the expander will generate the corresponding run-time check to evaluate
24422 (Resolve_Call): Check for legal type of procedure name or prefix that
24423 appears as a trigger in a triggering alternative.
24424 (Valid_Conversion): If expression is ambiguous and the context involves
24425 an extension of System, remove System.Address interpretations.
24426 (Resolve_Qualified_Expression): Reject the case of a specific-type
24427 qualification applied to a class-wide argument. Enhance comment
24428 to explain checking of Original_Node.
24429 (Resolve_Type_Conversion): The location of the error message was not
24430 general enough to handle the general case and hence it has been removed.
24431 In addition, this patch improves the text of the message.
24432 (Resolve_Type_Conversion): Add missing support for access to interface
24434 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24435 do not expand if the expression is the actual in a call, because proper
24436 expansion will take place when the call itself is expanded.
24437 (Resolve_Allocator): If the context is an unchecked conversion, the
24438 allocator inherits its storage pool, if any, from the target type of
24441 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24442 Javier Miranda <miranda@adacore.com>
24444 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24445 inherited interface operation that has an implementation, use the
24446 implementation to avoid spurious ambiguities.
24447 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24448 use the Corresponding_Record_Typ attribute to look for the interface
24449 because it is set by the expander (and hence it is not always
24450 available). For this reason we traverse the list of interfaces
24451 (available in the parent of the concurrent type).
24452 (Interface_Present_In_Ancestor): Handle entities from the limited view
24454 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24456 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24457 from the list of required components.
24458 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24459 primitive procedure of a limited interface with a controlling first
24461 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24463 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24464 capture if it is generated in the second operand of a short-circuit
24466 Do not capture values for variables with address clauses.
24467 (Is_Object_Reference): Treat a function call as an object reference only
24468 if its type is not Standard_Void_Type.
24470 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24472 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24473 to a variable that is statically known to be constant.

24487 Add documentation on environment variable syntax for Expand_Path
24489 * gnat_ugn.texi: Update documentation to include mention of -m switches
24490 Document new treatment of wide characters in max line length
24492 Remove -gnatL/-gnatZ switches, no longer used.
24493 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24496 * gnat_rm.texi: Add doc for two argument form of pragma
24497 Float_Representation.
24498 Add documentation for pragma No_Strict_Aliasing
24499 Add note that explicit component clause overrides pragma Pack.
24500 Add documentation of pragma Debug_Policy

25255 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25256 longer protected objects. They have been replaced by lower-level
25257 suspension objects made up by a mutex and a condition variable (or
25258 their equivalent given a particular OS) plus some internal data to
25259 reflect the state of the suspension object.
25260 (Initialize, Finalize): Add this initialization procedure for
25261 Suspension_Object, which is a controlled type.
25262 (Finalize): Add the finalization procedure for Suspension_Object,
25263 which is a controlled type.
25265 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25266 Ada.Synchronous_Task_Control because there is no longer a need for a
25267 VxWorks specific version of this package. Target dependencies
25268 has been moved to System.Task_Primitives.Operations.
25270 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25272 (InitializeCriticalSection, EnterCriticalSection,
25273 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25274 pCriticalSection by an anonymous access type so that we avoid problems
25275 of accessibility to local objects.

25281 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25282 set the environment task mask here.
25283 (Current_State): Add this function that returns the state of the
25285 (Set_False): Add this procedure that sets the state of the suspension
25287 (Set_True): Add this procedure that sets the state of the suspension
25288 object to True, releasing the task that was suspended, if any.
25289 (Suspend_Until_True): Add this procedure that blocks the calling task
25290 until the state of the object is True. Program_Error is raised if
25291 another task is already waiting on that suspension object.
25292 (Initialize): Add this procedure for initializing the suspension
25293 object. It initializes the mutex and the condition variable which are
25294 used for synchronization and queuing, and it sets the internal state
25296 (Finalize): Add this procedure for finalizing the suspension object,
25297 destroying the mutex and the condition variable.

25302 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25303 which provides a low-level abstraction (using operating system
25304 primitives) for Ada.Synchronous_Task_Control.
25305 This object is made up by a mutex (for ensuring mutual exclusion), a
25306 condition variable (for queuing threads until the condition is
25307 signaled), a Boolean (State) indicating whether the object is open,
25308 and a Boolean (Waiting) reflecting whether there is a task already
25309 suspended on this object.

25326 System.Parameters.No_Abort is True.
25328 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
25329 is no longer done in the body of s-taprop

25574 type derivation of private tagged types implementing interfaces.
25575 In this case some interface primitives may have been overriden

25721 access to subprograms must be recursive.
25722 (Is_Unchecked_Conversion): Improve the test that recognizes
25723 instantiations of Unchecked_Conversion, and allows them in bodies that
25724 are to be inlined by the front-end. When the body comes from an
25725 instantiation, a reference to Unchecked_Conversion will be an
25726 Expanded_Name, even though the body has not been analyzed yet.

25747 object or component (that is, when Is_Local_Anonymous_Access is true).
25748 Prevent the special checks for conversions of access discriminants in
25749 the case where the discriminant belongs to a nonlimited type, since
25750 such discriminants have their accessibility level defined in the same
25751 way as a normal component of an anonymous access type.
25752 (Resolve_Allocator): When an allocator's designated type is a class-wide
25753 type, check that the accessibility level of type given in the
25754 allocator's expression or subtype indication is not statically deeper

25774 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25775 check on possible violation of restriction No_Direct_Boolean_Operators

26782 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26785 error messages if expansion has been disabled due to previous
26786 (unrelated) errors).
26788 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26789 is disabled, the entity denoted by the argument is the access type
26790 itself, not an underlying record type, so there is no need to go back
26791 to the Corresponding_Remote_Type.

26801 denotes a type in the class.
26802 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26803 of Name_Generic_Dispatching_Constructor.
26805 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

26820 the case of renaming of stream attributes when the renaming denotes a
26821 generic formal subprogram association for an abstract formal subprogram.
26822 Check that the attribute is a primitive stream attribute (and not
26823 a class-wide stream attribute) and then rewrite the attribute name
26824 as the name of the appropriate compiler-generated stream primitive.

26828 * exp_util.adb (Remove_Side_Effects): Properly propagate arguments to

26836 itype whose parent is controlled and not yet frozen, do not create a
26837 freeze node for the itype if expansion is disabled.
26839 2005-03-29 Vincent Celier <celier@adacore.com>
26841 * make.adb (Gnatmake): Don't fail if the main project file is declared
26842 as having no Ada sources. Do not display message "no sources to
26843 compile" in quiet output.

27544 Update documentation on Must_Be_Byte_Aligned for new spec
27546 * tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
27547 exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
27548 uses of the Access_Disp_Table attribute to reference the first dispatch
27549 table associated with a tagged type. As
27550 part of the implementation of abstract interface types,
27551 Access_Disp_Table has been redefined to contain a list of dispatch
27552 tables (rather than a single dispatch table).
27553 Similarly, upgrade all the references to Tag_Component by the
27554 new attribute First_Tag_Component.
27555 (Find_Inherited_TSS): Moved to exp_tss.

27563 Bit packed array ops are only called if operands are known to be
27565 (Component_Equality): When returning an N_Raise_Program_Error statement,
27566 ensure that its Etype is set to Empty to avoid confusing GIGI (which
27567 expects that only expressions have a bona fide type).
27568 (Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
27569 determine the amount of data to be copied.
27571 * par.adb (P_Interface_Type_Definition): New subprogram that parses the

27599 (Task_Body_Procedure): Removed.
27600 (Set_Task_Body_Procedure): Removed.
27601 These subprogram have been removed because the attribute
27602 Task_Body_Procedure has been moved to the corresponding task type
27603 or task subtype entity to leave a field free to store the list
27604 of interfaces implemented by a task (for AI-345)
27605 Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
27606 (Null_Exclusion_Present): Change to Flag11, to avoid conflict with
27607 expression flag Do_Range_Check

27623 * exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
27624 attribute Task_Body_Procedure rather than the old semantic field that
27625 was available in the task_type_declaration node.
27627 * par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
27628 interface type definitions.
27629 (P_Formal_Derived_Type_Definition): Modified to handle the list of
27632 * par-ch9.adb (P_Task): Modified to handle the list of interfaces in a

27669 expression to the type of the object when the object is constant.
27670 Reverse defer_debug_incomplete_list before traversing it, so that trees
27671 are processed in the order at which they were added to the list. This
27672 order is important when using the stabs debug format.
27673 If we are deferring the output of debug information, also defer this
27674 output for a function return type.
27675 When adding fields to a record, prevent emitting debug information
27676 for incomplete records, emit the information only when the record is
27678 (components_to_record): New parameter defer_debug.

27686 unconstrained arrays properly.
27688 * gigi.h (write_record_type_debug_info): New function.
27689 Convert to use ANSI-style prototypes. Remove unused

27715 Expansion_Delayed and handle case when it's inside an
27716 N_Qualified_Expression.
27718 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27719 Comes_From_Generic, to recognize accurately that the parent type in a
27720 derived type declaration can be traced back to a formal type, because
27721 it is one or is derived from one, or because its completion is derived
27723 (Constrain_Component_Type): If component comes from source and has no
27724 explicit constraint, no need to constrain in in a subtype of the
27726 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27727 Minor change to propagate Is_Ada_2005 flag

27734 function returns "by target", dereference the target pointer using the
27735 type of the actual return value.
27736 <all>: Be prepared for a null gnu_result.
27737 (processed_inline_subprograms): Check flag_really_no_inline

27750 System.Pack_nn unit.
27752 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27754 Needed now that we do some processing for IN parameters as well. This
27755 may well fix some unrelated errors.
27756 (Expand_Call): Handle case of unaligned objects (in particular those
27757 that come from packed arrays).
27758 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27759 renamed entity is an inherited operation, re-expand the call using the
27760 original operation, which is the one to call.
27761 Detect attempt to inline parameterless recursive subprogram.
27762 (Represented_As_Scalar): Fix to work properly with private types
27763 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27764 accurate estimate. Yields True in far fewer cases than before,
27765 improving the quality of code that depends on this test.
27767 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27768 over both visible and private declarations to remove them from tree,
27769 and mark subprograms declared in package as eliminated, to prevent

27781 of an initialization call.
27783 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27785 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27786 that appears in the instantiation rather than the internal subtype
27787 generated in the wrapper package, to avoid anomalies in gigi when the
27788 target is derived from a private type whose full view is an access type.
27790 2005-03-15 Robert Dewar <dewar@adacore.com>
27792 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,

27800 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27801 here from exp_attr so it can be shared between exp_attr and exp_dist.
27802 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27803 all TSS names, not a subset thereof, and the previous name introduced
27804 an unnecessarily confusion that a distinction might exist between
27805 "OK" TSS names and some "not OK" TSS names.
27807 2005-03-15 Doug Rupp <rupp@adacore.com>
27809 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style

27818 when IN_RTS. This is to work around a bootstrap path problem.
27820 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27821 table and pass it to __gnat_install_SEH_handler().
27822 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.

27829 Arnaud Charlet <charlet@adacore.com>
27832 This change works fine when gnatlib is built from the gcc directory,
27833 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27834 is not passed to ada/Makefile.in, so more work is needed by a
27835 Makefile/configure expert.
27837 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27838 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27839 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27841 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27842 Run ranlib on libgccprefix.a
27843 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27844 (ADA_INCLUDE_SRCS): Split Ada packages.
27846 2005-03-15 Robert Dewar <dewar@adacore.com>
27848 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27850 * impunit.adb: Add GNAT.UTF_32
27852 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27854 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27855 now uses GNAT.UTF_32).
27857 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27858 capabilities for categorizing characters using Unicode categories
27860 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27862 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27863 instantiation that has been rewritten as a package body, retrieve spec
27864 to generate proper name for implicit_with_clause.
27865 (Install_Parents): Recognize a parent that is an instantiation but has
27866 been rewritten as a package declaration during analysis.
27868 2005-03-15 Javier Miranda <miranda@adacore.com>
27869 Ed Schonberg <schonberg@adacore.com>
27871 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27872 parameter reported some error we immediately return. This improves the
27873 behaviour of the frontend in case of errors.
27874 (Install_Parent, Remove_Parent): Introduce new flag
27875 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27876 ancestor of a generic child unit, when the child is being instantiated.
27877 (Inline_Instance_Body): If we are compiling the private
27878 part or the body of a child unit, restore the proper visibility of the
27879 parents after compiling the instance body.
27881 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27882 Javier Miranda <miranda@adacore.com>
27885 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27886 of a private type, in which case it is underlying_type that denotes
27887 the proper task. Also modified to use the new entity attribute
27888 that is directly available in the task type and task subtype entities
27889 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27890 arrays when other dimensions than the first are constrained by
27891 discriminants of an enclosing record.
27892 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27893 a combination of indexed and selected components, find ultimate entity
27894 and generate the appropriate reference for it, to suppress spurious
27896 (Note_Possible_Modification): If an entity name has no entity, return.
27897 (Is_Variable): A function call never denotes a variable.
27898 (Requires_Transient_Scope): For record types, recurse only on
27899 components, not on internal subtypes that may have been generated for
27900 constrained components.
27902 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27904 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27905 Eliminated as candidates for resolution. Both efficient, and avoids
27906 anomalies with operators declared in deleted code.
27907 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27908 expansion is disabled (as when compiling a generic) to prevent spurious
27909 warnings on prefixes of selected components.
27911 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27913 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27914 attached to a list before checking whether it appears in the private
27915 declarations of the current package.
27916 (Make_Inequality_Operator): Insert declaration in proper declarative
27917 list rather than just setting the Parent field, so that
27918 Is_Private_Declaration can handle it properly.
27920 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27922 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27923 a renaming a body, check that the renamed subprogram in not intrinsic.
27924 (Find_Direct_Name): If several use_visible entities hide
27925 each other, and the context is a predefined file compiled through
27926 rtsfind, keep only the entity that comes from a predefined file.
27928 2005-03-15 Geert Bosch <bosch@adacore.com>
27930 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27931 long float padding to also cover AMD64 and IA64.

28303 Corresponding_ Formal_Spec and simplify condition.
28304 (Use_One_Package): Check that scope of homonym of identifier is defined,
28305 before checking whether it is a wrapper package.
28306 Add support for wide wide character type
28308 * sem_eval.adb: Add support for wide wide character type.

28315 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28317 (Unit_Declaration_Node): Ditto.
28318 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28319 has a packed array type, the prefix has been rewritten into a type
28320 conversion. Determine variable-ness from the converted expression.
28321 Handle wide wide character cases.
28323 * stand.ads: Add types Wide_Wide_Character and Wide_Wide_String
28325 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28326 Remove ["0A"] from comment, since it can look like a line terminator.
28327 Currently we don't permit this, but this is under discussion by the
28328 ARG, and it is easy enough to use a different example.
28330 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28331 handling UTF-32 encoding for wide wide character.

28345 * a-except.adb (Rcheck_30): New subprogram. Addition of the message
28346 corresponding to CE_Null_Not_Allowed, and adjust the output of all the
28347 Rcheck subprograms.

28350 wrong null-exclusion value by a warning message.
28351 (Enable_Range_Check): Do range check if the prefix is an
28352 explicit dereference whose designated object is an unconstrained array.
28353 Current algorithm for removing duplicate checks is over-eager in this

28371 defined for subprogram renaming declarations. When set, the field
28372 indicates the defining entity of a corresponding formal subprogram
28373 when the renaming corresponds to a formal subprogram association in an
28375 (Set_Corresponding_Formal_Spec): New procedure to return
28376 Corresponding_Formal_Spec field.
28377 Minor changes of "=" to "in" in tests of N_Formal_Subprogram_Declaration
28378 (which is now a subtype).
28379 Char_Literal_Value field is now a Uint
28381 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28382 pointer to the base of the dispatch table.
28383 Minor changes to comments.

28389 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28390 describing the new layout.
28391 (Dispatch_Table): The expander computes the actual array size, allocates
28392 the Dispatch_Table record accordingly, and generates code that displaces
28393 the base of the record after the Typeinfo_Ptr component. The access to
28394 these components is done by means of local functions.
28395 (Offset_To_Top): New function.
28396 (Typeinfo_Ptr): New function.
28397 (Get_TSD): Modified to access the new position of the TSD.
28398 (Set_TSD): Modified to save the TSD in its new position.

28408 N_Formal_Subtype_Declaration (which is now a subtype).
28409 (Analyze_Formal_Subprogram): Add handling for
28410 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28411 dispatching, setting the controlling status of the formal parameters
28412 and result, and issuing an error if there is no controlling type for
28413 the formal subprogram.
28414 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28415 which is an unclean use of that field, we set the new field
28416 Corresponding_Formal_Spec to make the formal subprogram available to
28417 processing in Analyze_Subprogram_Declaration.
28418 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28419 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
28420 Constrained, so that it is is does not statically match its anonymous

28424 abstract formal subprograms in error check for functions returning
28425 abstract types. Set scope of new designator for
28426 a parameterless subprogram, so that it is available when checking the
28427 body for nested subprograms, before full analysis of said body.
28428 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28429 subprogram only if inner one comes from source.
28430 (Analyze_Function_Call): If the call is given in object notation, the
28431 analysis of the name rewrites the node and analyzes it with the proper
28432 argument list. After analyzing the name, if the call has been rewritten
28433 and the result type is set, no further analysis is needed.
28434 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28435 mark in function specification, in a context where the formals are
28436 visible and hide outer homographs.
28438 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28439 as the tagged type for the cases of abstract formal subprograms and
28440 renamings of those. Clean up spec comments.
28441 (Check_Dispatching_Context): Add error message to indicate "abstract
28442 procedure", covering the case of a call to a formal abstract procedure
28443 that has statically tagged operands.
28444 (Check_Dispatching_Call): Check for the case of an actual given by
28445 a tag-indeterminate function call whose type is an ancestor of the
28446 containing call's associated tagged type. This situation can occur
28447 for inherited primitives with function defaults. In this case we
28448 use the tagged type's tag directly as the controlling argument for
28450 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28452 * sprint.adb (Sprint_Node_Actual): Split
28453 N_Formal_Subprogram_Declaration into two alternatives for the new

28529 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28530 on the field if Pragma Component_Alignment (Storage_Unit).
28531 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28532 side-effects as if it were a constant; also make SAVE_EXPR to protect

28550 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28552 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28553 component of an array of arrays in an assignment context, and the
28554 aggregate has component associations that require sliding on
28555 assignment, force reanalysis of the aggregate to generate a temporary
28556 before the assignment.
28557 (Must_Slide): Make global to the package, for use in Gen_Assign.
28559 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28561 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28562 unchecked union with no inferable discriminants, return a
28563 Raise_Program_Error node, rather than inserting it at the point the
28565 (Expand_Record_Equality, Component_Equality): Handle properly the case
28566 where some subcomponent is an unchecked union whose generated equality
28567 code raises program error.

28575 Arnaud Charlet <charlet@adacore.com>
28577 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28578 address of the exception registration. The Win32 version of this
28579 routine calls __gnat_install_SEH_handler() to initialize the SEH
28580 (Structured Exception Handling) handler.
28581 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28582 SEH (Structured Exception Handling) now.
28583 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28584 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28585 preprocessor condition protecting the call to the extra eh setup
28586 subprogram, which is only available for the ppc target.
28587 (__gnat_clear_exception_count): replaced reference to
28588 variable taskIdCurrent by call to taskIdSelf(), cleaner.
28590 * seh_init.c: New file.

28593 (GNATBIND_OBJS): Idem.
28595 * misc.c (gnat_parse_file): Update call to __gnat_initialize. This
28596 routine takes a new parameter (a pointer to the exception registration
28597 for the SEH (Structured Exception Handling) support.
28599 * raise.h: (__gnat_install_SEH_handler): New prototype.
28600 Update copyright notice.
28602 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28632 2005-02-09 Vincent Celier <celier@adacore.com>
28634 * prj-makr.adb (Process_Directory): Put file name in canonical case
28635 before matching against the patterns.
28636 If gnatname has been invoked as <prefix>-gnatname
28637 then invoke the compiler as <prefix>-gcc, not just "gcc".
28639 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28641 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28642 with expansion disabled. The actual subtype is needed among other
28643 places when the selected component appears in the context of a loop
28644 bound, and denotes a packed array.
28645 (Operator_Check): Always use the first subtype in the
28646 error message, to avoid the appearance of internal base types.
28647 (Transform_Object_Operation): Copy each actual in full
28648 to the parameter associations of the constructed call, rather than
28649 using the shallow copy mechanism of New_Copy_List. This ensures that
28650 the chaining of named associations is done properly.
28651 (Complete_Object_Operation): Rewrite node, rather than
28652 replacing it, so that we can trace back to the original selected
28655 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28656 and calls that use object notation, if the called function is not
28657 declared in a withed unit, place the elaboration constraint on the
28658 unit in the context that makes the function accessible.
28659 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28660 imposes an elaboration constraint between two packages.
28662 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28664 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28665 views of a private type after handling its private dependents, to
28666 maintain proper stack discipline between entry and exit from the

28686 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28687 Slight fix to documentation of -gnaty with no parameters
28689 * xr_tabls.ads: Add ??? comment for missing overall comment
28691 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28692 we now use by default.
28694 * xsnames.adb: Adjust end of file test to look for five space followed
28695 by '#' instead of six spaces. The format of xsnames.adb was modified
28696 in the last update.
28698 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28701 * clean.adb: Minor reformatting.
28703 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28704 gnatname.adb: Minor reformatting
28705 Add 2005 to copyright output when utility is run
28707 * csets.adb: Eliminate obsolete comment
28709 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28712 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28714 2005-02-09 Sergey Rybin <rybin@adacore.com>
28716 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28717 the difference between compact and incompact layout and add the record
28718 representation clause to the example illustrating different layouts.
28719 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28720 component clauses").
28722 2005-02-09 Florian Villoing <villoing@adacore.com>
28724 * gnat_ugn.texi: Fix typos.
28725 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28727 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28728 in the generated documentation.

28763 from the VxWorks kernel) that is needed for getting the active
28764 priority of the different tasks.
28766 * s-atacco.ads, s-atacco.adb (Nothing): Remove this dummy procedure.
28767 Use a pragma Elaborate_Body in the spec file instead.
28768 Noticed by code reading.
28770 2005-02-09 Thomas Quinot <quinot@adacore.com>
28772 * exp_util.ads: Minor correction in comment.
28774 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28776 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,
28777 since this procedure is now too complex to be worth inlining.

29082 structure of GARLIC and PolyORB RPC receivers.
29083 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
29085 Simplify elaboration code for RCI packages.
29087 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29197 note that it applies to obsolete GNAT features, which was previously
29198 omitted. Second we contrast the behavior with that of the new
29199 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29200 Preliminary rewriting of GNAT & libraries chapter in order to take

29433 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29434 fields claimed addressable still have to be bitfields. Use
29435 value_factor_p instead of a raw binop construction to check for the
29436 position's alignment.

29443 Ed Schonberg <schonberg@adacore.com>
29445 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29446 with an implicit dereference as its prefix, use
29447 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29449 prefix is generated, if appropriate.
29451 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29452 dereference is rewritten to an explicit one, generate a reference to
29453 the entity denoted by its prefix using the original prefix node, so

29455 access value, if appropriate.
29457 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29458 emitting 'assigned but never read' warning on a variable on the basis

29472 an external name, to be handled by the back end.
29474 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29475 subprogram which is Imported with convention Intrinsic if an
29476 External_Name argument is specified.
29477 (Process_Import_Or_Interface): Properly diagnose link name argument.

29503 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29504 PCS-specific part of Add_Stub_Type.

29534 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29535 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29536 the body, to ensure that warnings are properly emitted for each accept
29537 statement of a given task entry.

29565 (Remove_Next): Same cleanup
29567 2004-12-07 Thomas Quinot <quinot@adacore.com>
29569 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29570 used to record an implicit dereference as a read operation on its
29571 prefix when operating under -gnatc. Necessary to avoid spurious
29572 'variable assigned but never read' warnings in that mode.
29573 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29574 is a non-overloaded implicit dereference, call the above subprogram to
29575 ensure proper recording of references.
29577 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29579 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs

29627 2004-12-07 Vincent Celier <celier@adacore.com>
29629 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29630 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29631 and -eit to -ept. Added qualifier
29632 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29634 2004-11-27 Andreas Schwab <schwab@suse.de>

29638 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29640 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29641 internal implementation unit GNAT.Sockets.Thin,
29642 as their usage for sockets is non-portable (using the read and write
29643 functions from the system runtime library is fine on UNIX but won't
29644 work under Windows).

29697 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29699 * gigi.h (others_decl, all_others_decl): New decls representing the
29700 new Others_Value and All_Others_Value objects.
29701 (struct attrib): Rename "arg" component as "args", since GCC expects a
29702 list of arguments in there.
29704 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29705 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29708 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29709 others_decl and all_others_decl instead of hardcoded dummy addresses
29710 to represent "others" and "all others" choices, which is cleaner and
29711 more flexible with respect to the possible eh pointer encoding policies.
29713 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29714 (process_attributes): Account for the naming change of the "args"
29715 attribute list entry component.
29717 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29718 cumulating attributes for different entities into a single list.
29719 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29720 attributes for the current entity and propagate first subtype
29721 attributes to other subtypes.
29722 <E_Procedure>: Attribute arguments are attr->args and not
29723 attr->arg any more.
29724 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29725 argument provided, as this is what GCC expects. Use NULL_TREE instead
29728 2004-11-18 Robert Dewar <dewar@adacore.com>
29730 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:

29742 procedures factors the common processing for building an RPC receiver
29743 for an RCI package or an RACW type.

29762 (Insert_Partition_Check): Remove fossile code.
29763 (First_RCI_Subprogram_Id): Document this constant.
29764 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29766 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29767 replaced with calls to Get_Library_Unit_Name_String. Previously there
29768 were several instances of the same code in different locations in the
29769 compiler; this checkin completes the replacement of all of these
29770 instances with calls to a common subprogram.
29771 Minor reformatting.
29773 * sem_dist.adb: Remove comment noting that RPC receiver generation
29774 should be disabled for RACWs that implement RASs.

29777 * sem_util.ads, sem_util.adb (Has_Stream): New function
29778 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29779 qualified name of a library unit into the name buffer.
29780 (Note_Possible_Modification): Generate a reference only
29781 if the context comes from source.
29783 * snames.ads (PCS_Names): New subtype corresponding to names of
29784 supported implementations of the Partition Communication Subsystem
29785 (PCS) (i.e. the runtime library support modules for the distributed

29789 Ed Schonberg <schonberg@adacore.com>
29791 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29792 (Has_Rep_Pragma): New function
29793 (Has_Attribute_Definition_Clause): New function
29794 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29795 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29797 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29799 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29800 (Expand_Pragma_Psect_Object): New procedure
29801 These procedures contain the revised and cleaned up processing for
29802 these two pragmas. This processing was formerly in Sem_Prag, but
29803 is more appropriately moved here. The cleanup involves making sure
29804 that the pragmas are properly attached to the tree, and that no
29805 nodes are improperly shared.
29807 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29808 pragmas to Exp_Prag, which is more appropriate.
29809 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29810 check for duplicates Remove use of Is_Psected flag, no longer needed.
29811 Use new Make_String_Literal function with string.
29813 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29814 that are functions return universal values, that have to be converted
29815 to the context type.
29816 Use new Make_String_Literal function with string.
29817 (Get_Stream_Convert_Pragma): New function, replaces the use of
29818 Get_Rep_Pragma, which had to be kludged to work in this case.
29820 * freeze.adb: Use new Has_Rep_Pragma function
29822 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29823 function with string.
29824 Use new Has_Rep_Pragma function.
29826 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29829 2004-11-18 Robert Dewar <dewar@adacore.com>
29831 * errout.ads, errout.adb: (First_Sloc): New function
29833 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29834 check (-gnatyx) instead of being included as a redundant construct
29837 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29838 Style_Check_Order_Subprograms.
29840 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29841 stylesw.adb: Add Style_Check_Xtra_Parens
29843 * usage.adb: Add line for -gnatyx (check extra parens)
29845 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29847 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29848 Robert Dewar <dewar@adacore.com>
29850 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29851 discriminant of a constrained subtype, analyze the copy of the
29852 corresponding constraint, because in some cases it may be only
29853 partially analyzed.
29854 Removes long-lived ??? comments.
29856 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29857 handled controlled or secondary-stack expressions within the
29858 iteration_scheme of a loop.
29860 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29861 bounds that may contain functions calls, to prevent memory leaks when
29862 the bound contains a call to a function that uses the secondary stack.
29863 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29864 generate temporaries for loop bounds that might contain function calls
29865 that require secondary stack and/or finalization actions.
29867 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29868 selected component and the selector is overloadable (not just a
29869 function) treat as function call, Analyze_Call will disambiguate if
29871 (Analyze_Selected_Component): Do not generate an actual subtype for the
29872 selected component if expansion is disabled. The actual subtype is only
29873 needed for constraint checks.
29874 (Analyze_Allocator): If restriction No_Streams is set, then do
29875 not permit objects to be declared of a stream type, or of a
29876 composite type containing a stream.
29878 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29879 No_Streams no longer prohibits with'ing this package.
29881 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29882 discriminants, but the parent base has unknown discriminants, there is
29883 no discriminant constraint to inherit. Such a discrepancy can arise
29884 when the actual for a formal type with unknown discriminants is a
29885 similar private type whose full view has discriminants.
29886 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29887 do not permit objects to be declared of a stream type, or of a
29888 composite type containing a stream.
29890 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29892 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29893 protected operations.
29895 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29896 generated name, it complicates decoding in gdb and hinders debugging
29897 of protected operations.
29898 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29899 flag for the protected entry barrier function.
29900 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29901 flag for the protected entry function.
29903 2004-11-18 Nicolas Setton <setton@adacore.com>
29905 * expect.c: Define __unix__ when __APPLE__ is defined.
29907 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29908 Darwin-specific section.
29910 * lang-specs.h: Change the placement of the %1 marker.
29911 Works around the fact that gcc adds -fPIC by default under Darwin.
29913 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29915 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29916 type of the object with the packed array type, set the Analyzed flag
29917 on the object if it is an entity or simple indexed component, to avoid
29918 spurious type errors.
29920 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29922 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29923 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29924 separate line from the version message.
29926 2004-11-18 Ed Falis <falis@adacore.com>
29928 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29930 (init_float): Eliminate initialization of floating point status for
29931 AE653. The instructions have no effect for vThreads.
29933 2004-11-18 Vincent Celier <celier@adacore.com>
29935 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29936 gnatbind is invoked with -shared.
29938 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29940 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29941 for Detect_Blocking which is redundant with the check done within the
29942 procedure Protected_Single_Entry_Call.
29943 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29944 Detect_Blocking which is redundant with the check done within the
29945 procedure Protected_Single_Entry_Call.
29947 2004-11-18 Vincent Celier <celier@adacore.com>
29949 * makegpr.adb (Compile): Put the compiling switches (in package
29950 Compiler and on the command line) immediately after "-c", instead of
29951 at the end of the command line invocation of the compiler, when
29952 compiling a non-Ada file.
29953 (Build_Global_Archive): When there is no need to rebuild the archive,
29954 set Global_Archive_Exists, so that the archive is passed to the linker
29957 2004-11-18 Robert Dewar <dewar@adacore.com>
29958 Sergey Rybin <rybin@adacore.com>
29961 Remove extra paren check from list of checks for redundant constructs
29962 Add documentation of new -gnatyx style check (check extra parens)
29963 Remove paragraph about gnatelim debug options.
29965 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29966 objects rather than forbidding dependencies on the package Ada.Streams.
29968 * sinfo.ads: Add ??? note that we should document pragmas passed to
29971 * g-expect.ads: Fix a few typos in the comments.
29973 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29975 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29978 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29980 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29982 2004-11-07 Andreas Schwab <schwab@suse.de>
29984 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29986 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29989 * Makefile.in (darwin): Set soext to .dylib.
29991 2004-10-26 Vincent Celier <celier@gnat.com>
29992 Thomas Quinot <quinot@act-europe.fr>
29994 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29995 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29996 there is no use of GNAT.Sockets.Constants.
29997 Remove remaining pragma Import for C_Write
29998 Remove C_Read and C_Write from internal implementation unit
29999 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30000 the read and write functions from the system runtime library is fine
30001 on UNIX but won't work under Windows).
30003 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30004 (Check_Selector): Use C_Recv instead of C_Read.
30005 Selectors are the GNAT.Sockets abstraction to perform a select()
30006 call on a set of descriptors. To allow abortion of an ongoing
30007 select operation, some data is written to a dedicated socket that
30008 is always monitored.
30009 Under Windows, the write and read library functions cannot operate
30010 on sockets, so we need to use send and recv instead, which is portable
30011 across all supported platforms.
30013 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30014 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30015 (using the read and write functions from the system runtime library is
30016 fine on UNIX but won't work under Windows).
30018 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30020 * mlib-tgt-darwin.adb: New file.
30022 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30023 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30024 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30025 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30028 * Makefile.in: Add support for building shared libraries under Darwin.
30029 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30030 the low level EH init subprogram to be called from __gnat_initialize.
30032 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30033 indicates which options to pass to the archive indexer.
30035 * mlib-utl.adb: Add support for calling ranlib with additional
30036 options. This is needed for instance under Mac OS X.
30037 (Ranlib_Options): New global variable, used to store the potential
30038 options to pass to ranlib.
30039 (Ar): Use Ranlib_Options when spawning ranlib.
30040 (Initialize): Set the value of ranlib option.
30042 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30044 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30045 instead of 8K, to reflect the real potential needs for stack-checking
30048 2004-10-26 Pascal Obry <obry@gnat.com>
30050 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30052 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30053 Windows only the initial thread stack size can be set so it is good to
30054 start we a low stack size.
30055 The OS will adjust the size as needed.
30057 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30058 Nicolas Setton <setton@act-europe.fr>
30060 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30061 "__unix__" instead of "unix".
30062 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30063 sections were just mistakenly ignored. The former is
30064 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30065 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30066 of hpux. This prevents an unwanted definition of the symbol
30067 convert_addresses in adaint.o.
30069 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30071 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30072 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30074 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30076 * a-filico.ads, a-filico.adb: fix incorrect header.
30078 2004-10-26 Javier Miranda <miranda@gnat.com>
30080 * a-ststio.ads: Fix typo in identifier
30082 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30084 * sem_ch4.adb: Minor reformatting.
30086 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30088 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30089 enabled, check the result of unary and binary operations when the
30090 expression is the right-hand side of an assignment.
30092 2004-10-26 Vincent Celier <celier@gnat.com>
30094 * clean.adb (Delete): Do not output warnings when in quiet output and
30095 not in verbose mode.
30096 (Force_Deletions): New Boolean flag, defaulted to False
30097 (Delete): Only delete a file if it is writable, and when
30098 Force_Deletions is True.
30099 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30100 (Usage): Line for new switch -f
30101 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30104 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30106 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30107 JM type only if its size matches that of the wrapper. When a size is
30108 prescribed and the field is not aliased, remove the wrapper of a JM
30109 type only if the size is not greater than that of the packed array.
30110 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30113 2004-10-26 Geert Bosch <bosch@gnat.com>
30115 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30116 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30117 (Pred): Implement in terms of Succ.
30119 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30121 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30122 unchecked conversion is safe for in-place use if the expression of the
30123 conversion is safe.
30124 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30125 be expandable in place even if the aggregate does not come from source.
30126 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30127 designated object of an allocator in place, rather than building it
30128 first on the stack. The previous scheme forces a full copy of the array,
30129 and may be altogether unsusable if the size of the array is too large
30130 for stack allocation.
30132 2004-10-26 Robert Dewar <dewar@gnat.com>
30134 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30135 compares if the component is atomic.
30137 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30138 array assignment if the component type is atomic.
30140 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30141 Eric Botcazou <ebotcazou@act-europe.fr>
30143 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30144 is aliased and is a by_reference type, do not pass by copy.
30145 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30146 detect whether the call is in the right side of an assignment or
30147 the expression of an object declaration. Recurse on component
30148 association within aggregates.
30149 Call it in the condition that determines whether the temporary is
30150 necessary for correct stack-checking.
30152 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30154 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30155 RACW_Type, used in the PolyORB version.
30156 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30157 version and the GARLIC version.
30159 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30160 Rename RCI_Info to RCI_Locator for better consistency between the
30161 GARLIC and PolyORB versions of the distributed systems annex.
30162 (DSA_Implementation_Name): This enumeration lists the possible
30163 implementations of the Partition Communication Subsystem for the
30164 Distributed Systems Annex (DSA). The three available implementations
30165 are the dummy stub implementation (No_DSA), and two versions based on
30166 two different distribution runtime libraries: GARLIC and PolyORB. Both
30167 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30169 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30172 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30173 between the GARLIC and PolyORB versions of the distributed systems
30175 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30177 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30179 * gnat1drv.adb: Suppress calling the back end when
30180 Frontend_Layout_On_Target is true.
30182 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30184 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30185 Set_Read_Only): New subprograms.
30186 These new routines allow the user to set or unset the Owner execute
30187 and Owner write permission flags on a file.
30189 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30190 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30192 2004-10-26 Matthew Gingell <gingell@gnat.com>
30194 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30196 2004-10-26 Pascal Obry <obry@gnat.com>
30198 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30199 memory before the faulting page we properly test the process read
30200 access for this address using appropriate Win32 routine.
30201 (HPUX sections): guard with "__hpux__" instead of "hpux".
30203 2004-10-26 Robert Dewar <dewar@gnat.com>
30205 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30206 entry parameter if pragma Unreferenced set, since we do not properly
30207 handle the case of multiple parameters.
30209 2004-10-26 Vincent Celier <celier@gnat.com>
30211 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30212 (Ada_Objects_Path.Add): For a library project, add to the object path
30213 the library directory only if there is no object directory or if the
30214 library directory contains ALI files.
30215 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30217 2004-10-26 Vincent Celier <celier@gnat.com>
30219 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30220 extension of library projects.
30222 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30223 path defaults to ".:<prefix>/lib/gnat".
30224 (Parse): For an extending all project, allow direct import of a project
30225 that is virtually extended.
30227 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30228 the specified name is directly imported, return its ID. Otherwise, if
30229 an extension of this project is imported, return the ID of the
30232 2004-10-26 Robert Dewar <dewar@gnat.com>
30234 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30235 (Sub3): New procedure, used by Scaled_Divide
30236 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30237 correct more than one instance of failure to propagate carries
30239 (Double_Divide): Handle overflow case of largest negative number
30240 divided by minus one.
30242 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30243 the case of a quotient value out of range.
30246 2004-10-26 Robert Dewar <dewar@gnat.com>
30248 * s-bitops.adb (Bit_Eq): Remove redundant check.
30250 * s-bitops.ads: Minor comment updates
30251 Change some occurrences of Address to System.Address
30253 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30255 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30257 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30258 accessibility check to prefix that is a protected operation.
30260 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30262 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30263 empty, post message on stub.
30265 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30266 Javier Miranda <miranda@gnat.com>
30268 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30269 current instance appears within a unit that is directly in the context
30271 Used to determine whether the body of the instance should be analyzed
30272 immediately after its spec, to make its subprogram bodies available
30273 for front-end inlining.
30274 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30275 constraint is not allowed on the component type (AARM 12.5.3(3))
30277 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30279 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30280 'Storage_Pool): enhance, document & limit detection of non-sharable
30283 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30285 * s-pooglo.ads: Add more documentation now that this pool is properly
30288 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30290 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30291 or protected type with discriminants, do not constrain the
30292 corresponding record type if the subtype declaration has no
30293 discriminant constraints. This can be the case in source code, or in
30294 the subtype declaration created to rename an actual type within an
30297 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30299 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30300 different kind of stub (possibly wrong name for file), do not check
30302 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30303 includes call to some function that returns an unconstrained type, do
30306 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30308 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30309 appear in the code for the main unit. Dependencies among units in the
30310 context of the main unit are established when those other units are
30311 compiled. Otherwise spurious elaboration constraints can generate
30312 incorrect elaboration circularities.
30314 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30315 Ed Schonberg <schonberg@gnat.com>
30317 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30318 subprogram is called with a parameter that is not an object name. This
30319 situation arises for some cases of illegal code, which is diagnosed
30320 later, and in this case it is wrong to call Is_Aliased, as that might
30321 cause a compiler crash.
30322 (Explain_Limited_Type): Refine previous fix to include
30323 inherited components of derived types, to provide complete information.
30325 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30326 is the prival for a protected object.
30327 It is necessary to mark this entity as a variable, in addition to
30328 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30329 modified to avoid checking the Aliased flag on entities that are not
30330 objects. (Checking that flag for non-objects is erroneous and could
30331 lead to a compiler crash).
30333 2004-10-26 Robert Dewar <dewar@gnat.com>
30335 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30336 X_Frac = 0.5, then we know that the number X must be positive.
30337 (Succ): Remove the same redundant test, and also fix the primary test
30338 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30340 (Decompose): Add fuller comments to spec
30342 2004-10-26 Pascal Obry <obry@gnat.com>
30344 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30345 validity (process must have read access). Set to 0 in all other cases.
30346 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30347 violation on Win32.
30348 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30349 segmentation violation.
30351 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30353 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30354 whose type is a constructed subtype of an aliased object with an
30355 unconstrained nominal subtype, convert the actual to the constructed
30356 subtype before taking its address.
30358 2004-10-26 Vincent Celier <celier@gnat.com>
30360 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30361 (Is_Path_Name_Case_Sensitive): New function
30363 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30364 (Base_Name, Simple_Name, Current_Directory, Compose,
30365 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30368 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30369 Vasiliy Fofanov <fofanov@act-europe.fr>
30370 Vincent Celier <celier@gnat.com>
30372 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30373 "memory management issues" section and document some of the useful
30374 memory pools provided as part of the GNAT library.
30375 Remove "virtual" from declaration of A::method2 in
30376 the simple example of Ada/C++ mixed system.
30377 Library Projects may be virtually extended: their virtual extensions
30378 are not Library Projects.
30379 Added section on extending project hierarchies.
30381 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30383 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30385 (__gnat_portable_spawn): Remove const.
30387 * mingw32.h (MAXPATHLEN): Check for previous definition.
30389 2004-10-17 Matthias Klose <doko@debian.org>
30391 * gnatvsn.ads: Set gnat library version to 4.0.
30393 2004-10-05 Vincent Celier <celier@gnat.com>
30395 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30397 2004-10-04 Laurent Guerby <laurent@guerby.net>
30400 * Makefile.in: Define and use RANLIB_FLAGS.
30402 2004-10-04 Pascal Obry <obry@gnat.com>
30404 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30405 other x86 platforms).
30407 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30409 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30410 in general and triggers stack alignment adjustment for thread entry
30411 points on targets where this is necessary.
30413 2004-10-04 Bernard Banner <banner@gnat.com>
30416 * Makefile.in: Add section for powerpc linux
30417 Add variant i-vxwork-x86.ads
30419 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30421 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30423 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30424 table registration calls when need be. Ensures no reference to the crt
30425 ctors symbol are issued in the SJLJ case, which avoids possible
30426 undefined symbol errors in the case of modules to be statically linked
30429 2004-10-04 Javier Miranda <miranda@gnat.com>
30431 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30432 in-line the code corresponding to subprogram Analyze_Actuals. In
30433 addition, analyze the actuals only in case of subprogram call.
30435 2004-10-04 Ed Falis <falis@gnat.com>
30437 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30439 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30441 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30442 in the documentation.
30444 2004-10-04 Robert Dewar <dewar@gnat.com>
30446 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30448 (Analyze_Block_Statement): Add circuitry to detect following dead code
30449 (Check_Unreachable_Code): Handle case of block exit
30451 2004-10-04 Robert Dewar <dewar@gnat.com>
30453 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30454 (XMatchD): Avoid warning for Logic_Error call
30456 2004-10-04 Robert Dewar <dewar@gnat.com>
30458 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30459 consider expressions buried within a procedure actual to be an actual.
30460 This caused some blowups with uses of packed slices within a procedure
30463 2004-10-04 Robert Dewar <dewar@gnat.com>
30465 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30466 longer need to be initialized to zero.
30467 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30468 initialized to zero.
30470 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30471 considered valid, even if the representation is modular. That's correct
30472 now that we no longer initialize packed modular arrays to zero.
30474 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30475 suffixes. These are now documented as the only cases in which the
30476 debugger ignores outer records.
30477 Previously, the spec allowed arbitrary suffixes for this purpose.
30478 Change name of LJM to JM for packed array pad records
30479 Create separate section on packed array handling, and add a whole new
30480 set of comments to this section describing the situation with packed
30481 modular types and justification requirements depending on endianness.
30483 2004-10-04 Robert Dewar <dewar@gnat.com>
30485 * a-except.adb: Add a comment for last change
30487 * einfo.ads: Minor spelling correction in comment
30489 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30491 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30494 * sem_util.ads: Minor comment update
30496 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30498 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30499 Inline_Always when in Configurable_Run_Time mode.
30501 * sem_prag.adb (Process_Convention): If entity is an inherited
30502 subprogram, apply convention to parent subprogram if in same scope.
30503 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30504 when in Configurable_Run_Time mode.
30506 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30508 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30509 class_wide type after component list has been inherited.
30511 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30513 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30514 Denotes_Previous_Actual, to handle properly the case of a private
30515 actual that is also the component type of a subsequent array actual.
30516 The visibility status of the first actual is not affected when the
30517 second is installed.
30518 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30519 make fully recursive the treatment of formals of packages declared
30521 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30522 the above on exit from an instantiation.
30523 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30524 current instantiation which is now complete.
30525 (Analyze_Package_Instantiation): No instantiated body is needed if the
30526 main unit is generic. Efficient, and avoid anomalies when a instance
30527 appears in a package accessed through rtsfind.
30529 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30531 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30532 do not generate a declaration for a temporary if the call is part of a
30533 library-level instantiation.
30535 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30537 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30538 searching for a limited component to flag.
30540 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30541 expansion of Input, to account for the fact that the implicit call
30542 generated by the attribute reference must freeze the user-defined
30543 stream subprogram. This is only relevant to 'Input, because it can
30544 appear in an object declaration, prior to the body of the subprogram.
30546 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30547 expansion can proceed and further errors uncovered.
30548 (Minor clean up): Fix cases of using | instead of \ for continuation
30551 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30553 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30555 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30556 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30557 Use gcc_assert and gcc_unreachable.
30559 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30560 specified alignment before validating size.
30561 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30562 stripped-down declaration for the type of the inner field when making
30565 * utils.c (finish_record_type): Do not compute the size in units
30566 incrementally. Instead compute it once for the rep clause case.
30567 Use gcc_assert and gcc_unreachable.
30569 2004-10-04 Vincent Celier <celier@gnat.com>
30571 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30573 (Is_Valid_Path_Name): Take '/' as a directory separator.
30575 2004-10-04 Vincent Celier <celier@gnat.com>
30577 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30578 (Extended_Project) only if Extended_Project is defined, to avoid
30580 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30582 (Parse_Single_Project): Ditto.
30584 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30585 Add_To_Project_Path for virtual projects.
30587 2004-10-04 Vincent Celier <celier@gnat.com>
30589 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30590 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30591 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30592 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30593 parameter Options_2.
30595 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30596 Build_Dynamic_Library with an empty Options_2.
30598 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30601 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30602 directory separator, if any.
30603 (Gprmake): Do not allow mains on the command line for library projects.
30604 Do not attempt to link when the project is a library project.
30605 (Library_Opts): New table to store Library_Options.
30606 (Build_Library): If Library_Options is specified, pass these options
30607 when building a shared library.
30609 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30611 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30612 the end of this procedure now that the unlock operation was inserted
30615 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30617 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30618 corresponding to the Preallocated_Stacks flags in System.
30619 (Get_Target_Parameters): Including the processing for
30620 Preallocated_Stacks.
30622 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30623 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30628 system-hpux.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
30629 system-vxworks-mips.ads, system-os2.ads, system-interix.ads,
30630 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30631 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30632 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30633 used to signal whether the compiler creates the required stacks and
30634 descriptors for the different tasks (when True) or it is done by the
30635 underlying operating system at run time (when False).
30636 It is initially set to False in all targets.
30638 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30639 if it is supported by the target.
30640 (Make_Task_Create_Call): Pass the stack address if it has been
30641 previously created. Otherwise pass a Null_Address.
30643 * snames.adb: Add _stack.
30645 * snames.ads: Add Name_uStack. Required to allow the expander to
30646 statically allocated task stacks.
30648 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30649 Stack_Address argument.
30650 Check that its value is equal to Null_Address because this target does
30651 not support the static stack allocation.
30653 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30655 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30658 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30660 * exp_dist.adb: Split declaration of asynchronous flag out of
30661 Add_RACW_Read_Attribute.
30662 Minor reformatting for better alignment with PolyORB version.
30663 Store the entity for the asynchronous flag of an RACW, rather than the
30664 expression, in the asynchronous flags table. This will allow this flag
30665 to be used in other subprograms beside Add_RACW_Read_Attribute.
30667 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30669 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,
30670 g-soccon-aix.ads, g-soccon-irix.ads, g-soccon-hpux.ads,
30671 g-soccon-interix.ads, g-soccon-solaris.ads, g-soccon-vms.adb,
30672 g-soccon-mingw.ads, g-soccon-vxworks.ads, g-soccon-freebsd.ads,
30673 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30674 sockets constant MSG_NOSIGNAL (Linux-specific).
30675 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30676 all Send operations.
30677 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30678 from trigerring SIGPIPE.
30679 Rename components to avoid clash with Ada 2005 possible reserved
30681 (Check_Selector): When the select system call returns with an error
30682 condition, propagate Socket_Error to the caller.
30684 2004-10-01 Jan Hubicka <jh@suse.cz>
30686 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30688 2004-09-23 Robert Dewar <dewar@gnat.com>
30691 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30692 instead do this at freeze time (we won't do it if there is an address
30694 Change "pragma inline" to "pragma Inline" in information and error
30696 Minor reformatting.
30698 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30699 right way of doing things after all.
30700 (Freeze_Entity): For object, set Is_Public for imported entities
30701 unless there is an address clause present.
30703 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30705 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30706 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30707 ensures proper handling of types with rep clauses, which might have
30708 their TYPE_SIZE set already.
30710 2004-09-21 Robert Dewar <dewar@gnat.com>
30712 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30713 packed array types in both little- and big-endian cases. This change
30714 ensures that we no longer count on the unused bits being initialized
30715 for such types (and in particular ensures that equality testing will
30716 only read the relevant bits).
30717 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30718 These changes mean that we no longer need to initialize small packed
30720 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30721 optimization to an LJM field as to its parent field.
30723 * ada-tree.h, trans.c, utils.c, utils2.c:
30724 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30726 2004-09-20 Jan Hubicka <jh@suse.cz>
30728 * utils.c (gnat_finalize): Remove.
30729 (end_subprog_body): Directly call cgraph_finalize_function;
30730 do not lower the nested functions.
30732 2004-09-20 Robert Dewar <dewar@gnat.com>
30735 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30736 if an address clause is present, since that means that the Import
30739 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30741 * 5tsystem.ads: Removed, no longer used.
30743 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30744 Zack Weinberg <zack@codesourcery.com>
30746 * ada-tree.def: Use tree_code_class enumeration constants
30747 instead of code letters.
30748 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30749 Update for new tree-class enumeration constants.
30751 2004-09-17 Vincent Celier <celier@gnat.com>
30753 * prj-attr-pm.ads, prj-attr-pm.adb: New files, to split some private
30754 capabilities of the general project manager.
30756 2004-09-09 Vincent Celier <celier@gnat.com>
30758 * a-direct.ads: Add pragma Ada_05
30759 (Directory_Entry_Type): Give default value to component Kind to avoid
30760 not initialized warnings.
30762 * a-direct.adb (Current_Directory): Remove directory separator at the
30764 (Delete_Directory, Delete_Tree): Raise Name_Error if Directory is not
30765 an existing directory.
30766 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning

30851 the protected action nesting level.
30852 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30853 protected action nesting level.

30858 Protected_Action_Nesting.
30860 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30861 Common_ATCB record. It contains the dynamic level of protected action
30862 nesting for each task. It is needed for checking whether potentially
30863 blocking operations are called from protected operations.
30864 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30865 Detect_Blocking is active or not in the partition.
30867 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,

30901 contains the required machinery for handling that.
30903 * sem_util.ads: Change comment associated to procedure
30904 Check_Potentially_Blocking_Operation.
30905 This procedure does not insert a call for raising the exception because
30906 that is currently done by the run time.

30925 Detect_Blocking is active and delay is called from a protected
30928 * bindgen.adb (Gen_Adainit_Ada): When generating the call to

30942 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30943 Update API in placeholder implemetation of s-parint to reflect changes
30944 in distribution runtime library.
30946 * sem_ch3.adb (Expand_Derived_Record): Rename to
30947 Expand_Record_Extension.
30949 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30950 primitive operations of potentially distributed object types that have
30951 non-controlling anonymous access formals.
30953 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30955 New implementation of expansion for remote access-to-subprogram types,
30956 based on the RACW infrastructure.
30957 This version of sem_dist is compatible with PolyORB/DSA as well as
30960 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30961 Asynchrronous that applies to a remote access-to-subprogram type, mark
30962 the underlying RACW type as asynchronous.
30964 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30965 __gnat_using_gnu_linker to 1.

30976 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30977 a component declaration must remain attached at that point in the
30978 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30979 It is therefore necessary to take a copy of the expression when building
30980 the corresponding assignment statement in the init proc.
30981 As a side effect, in the case of a derived record type, we now see the
30982 original expression, without any rewriting that could have occurred
30983 during expansion of the ancestor type's init proc, and we do not need
30984 to go back to Original_Node.
30986 * exp_ch3.ads (Expand_Derived_Record): Rename to

30994 subprogram. The proxy object is used as the designated object
30995 for RAS values on the same partition (unless All_Calls_Remote applies).
30996 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30997 System.Partition_Interface.Get_Unique_Remote_Pointer.

31003 based on the RACW infrastructure.
31005 * exp_dist.ads (Copy_Specification): Update comment to note that this
31006 function can copy the specification from either a subprogram
31007 specification or an access-to-subprogram type definition.
31009 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31011 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31012 in an instance, between an explicit subprogram an one inherited from a
31013 type derived from an actual.
31015 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31016 add a polling call if the subprogram is to be inlined by the back-end,
31017 to avoid repeated calls with multiple inlinings.
31019 * checks.adb (Apply_Alignment_Check): If the expression in the address
31020 clause is a call whose name is not a static entity (e.g. a dispatching
31021 call), treat as dynamic.

31039 enable map file generation. Add the right option to generate the map
31040 file if Map_File is set to True.

31267 for a global aliased object with a variable size and an unconstrained
31268 nominal subtype, pretend there is no initializer if the one we have is
31269 incomplete, and avoid referencing an inexistant component in there. The

31330 returning C.int, to avoid using a derived boolean type.
31332 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31361 ignore overflows on low and high bounds of an index to also account for
31362 differences in signedness between sizetype and gnu_index_subtype.

33215 2004-06-07 Thomas Quinot <quinot@act-europe.fr>
33217 * bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
33218 the index of the last element is Units.Last, not Units.Table'Last
33219 (which is usually not a valid index within the actually allocated
33220 storage for the table).
33222 * exp_ch4.adb (Insert_Dereference_Action): Change predicate that
33223 determines whether to generate a call to a checked storage pool

33257 hand side. Warnings are now properly emitted when variables or prefixes
33258 are assigned but not read.
33260 * sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
33261 left hand side referenced variables. Private access types do not

33285 interpretations for rewritten right operand.
33286 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33716 actions if the object is a renaming.
33718 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
33719 Check_Formal_Package_Instance, to determine more precisely when the
33720 formal and the actual denote the same entity.
33722 2004-05-14 Javier Miranda <miranda@gnat.com>
33724 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33726 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33727 corresponding to a private_with must be removed from visibility; it
33728 will be made visible later, just before we analyze the private part of
33730 (Check_Private_Child_Unit): Allow private_with clauses in public
33732 (Install_Siblings): Make visible the private entities of private-withed
33734 (Install_Withed_Unit): Do not install the private withed unit if we
33735 are compiling a package declaration and the Private_With_OK flag was
33736 not set by the caller. These declarations will be installed later,
33737 just before we analyze the private part of the package.
33739 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
33740 during the evaluation of the expression that initializes the object,
33741 decorate it with the expected type to avoid cascade errors.
33744 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
33745 subprogram we have to install the private_with clauses after its
33746 specification has been analyzed (as documented in AI-262.TXT).
33748 * sem_ch8.adb (Has_Private_With): New function. Determines if the
33749 current compilation unit has a private with on a given entity.
33750 (Find_Direct_Name): Detect the Beaujolais problem described in
33753 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
33754 provides the functionality of the function Is_Ancestor that was
33755 previously available in sem_ch10. It has been renamed to avoid
33758 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
33760 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
33762 * utils.c (build_vms_descriptor): Use SImode pointers.

33949 Fixes undefined symbols in IA64 gnatlib.
33951 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
33953 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
33954 Short_Address). This will be moved to system.auxdec.

33959 present with a call to Discard_Node.
33961 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33962 Analyze on the library unit node after generation of distribution stub
33963 constructs. The call was a no-op because Unit_Node has already been
33964 Analyzed, and the tree fragments for the distribution stubs are
33965 analyzed as they are inserted in Exp_Dist.
33966 Update comment regarding to distribution stubs to reflect that we
33967 do not generate stub in separate files anymore.
33969 * einfo.ads: Clarify the fact that a tagged private type has the
33970 E_Record_Type_With_Private Ekind.
33972 * erroutc.adb: Minor reformatting

33981 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33984 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
33985 has been rewritten as an explicit dereference, retrieve type of
33986 original node to check for possibly unconstrained record type.
33988 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33990 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33991 overriding, use the operation of the parent unconditionally.
33993 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
33994 operation when either operand is a literal, to avoid further
33997 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
33998 overridden by a previous explicit declaration, mark the previous entity
34001 * sem_disp.adb (Check_Dispatching_Operation): New predicate
34002 Is_Visibly_Controlled, to determine whether a declaration of a
34003 primitive control operation for a derived type overrides an inherited
34004 one. Add warning if the explicit declaration does not override.
34006 2004-05-10 Vincent Celier <celier@gnat.com>
34008 * gnatls.adb (Gnatls): Initialize Snames, to avoid assertion error in
34009 some cases when the sources are no longer present.
34011 * make.adb (Collect_Arguments): Fail if an external source, not part
34012 of any project need to be compiled, when switch -x has not been
34015 * makeusg.adb: Document new switch -x
34017 * opt.ads (External_Unit_Compilation_Allowed): New Boolean flag,
34018 defaulted to False.
34020 * switch-m.adb (Scan_Make_Switches): New switch -x
34022 * vms_data.ads: Add VMS qualifier /NON_PROJECT_UNIT_COMPILATION for
34023 gnatmake switch -x.
34025 * gnat_ugn.texi: Document new gnatmake switch -x
34027 2004-05-10 Eric Botcazou <ebotcazou@act-europe.fr>
34029 * misc.c (gnat_init_options): Set flag_zero_initialized_in_bss to 0.
34031 * utils.c (create_var_decl): Do not modify the DECL_COMMON flag.
34032 (process_attributes): Likewise.
34034 2004-05-10 Joel Brobecker <brobecker@gnat.com>
34036 * s-inmaop.ads: Fix spelling mistake in one of the comments.
34038 2004-05-10 Robert Dewar <dewar@gnat.com>
34040 * gnat_ugn.texi: Document that for config pragma files, the maximum
34041 line length is always 32767.
34043 * gnat_rm.texi: For pragma Eliminate, note that concatenation of string
34044 literals is now allowed.
34046 * gnat-style.texi: Remove statement about splitting long lines before
34047 an operator rather than after, since we do not follow this rule at all.
34048 Clarify rule (really lack of rule) for spaces around exponentiation
34050 * sem_elim.adb: Allow concatenation of string literals as well as a
34051 single string literal for pragma arguments.
34053 * sem_prag.ads, sem_prag.adb: (Is_Config_Static_String): New function
34055 * a-textio.adb (Terminate_Line): Do not add line feed if nothing
34056 written for append case.
34058 * frontend.adb: Changes to avoid checking max line length in config
34061 * g-os_lib.ads: Minor reformatting
34063 * mlib-utl.adb: Do not define Max_Line_Length locally (definition was
34064 wrong in any case. Instead use standard value. Noticed during code
34067 * opt.ads (Max_Line_Length): New field, used to implement removal of
34068 limitation on length of lines when scanning config pragma files.
34070 * osint.ads, prj-dect.adb, prj-strt.adb, prj-tree.adb,
34071 makeutl.ads, makeutl.adb: Minor reformatting

35133 2004-04-08 Olivier Hainque <hainque@act-europe.fr>
35135 * sem_prag.adb (Set_Exported): Warn about making static as result of
35136 export only when the export is coming from source. This may be not
35137 be true e.g. on VMS where we expand export pragmas for exception codes
35138 together with imported or exported exceptions, and we don't want the
35139 user to be warned about something he didn't write.
35141 2004-04-08 Thomas Quinot <quinot@act-europe.fr>
35143 * sem_util.adb (Note_Possible_Modification): Reorganize to remove code
35144 duplication between normal entities and those declared as renamings.
35145 No functional change.
35147 * s-fileio.ads (Form): Remove pragma Inline, as we cannot currently
35148 inline functions returning an unconstrained result.

35213 * make.adb (Scan_Make_Arg): Pass any -fxxx switches to gnatlink, not
35214 just to the compiler.

35243 (Leading_Part): Still perform truncation to machine number if the
35244 specified radix_digits is greater or equal to machine_mantissa.
35246 2004-04-05 Javier Miranda <miranda@gnat.com>
35248 * par-ch3.adb: Complete documentation of previous change
35249 Correct wrong syntax documentation of the OBJECT_DECLARATION rule

35254 * par-ch6.adb: Complete documentation of previous change.
35256 * sinfo.ads: Fix typo in commment.
35258 2004-04-05 Ed Schonberg <schonberg@gnat.com>
35260 * sem_ch3.adb (Inherit_Components): If derived type is private and has

35262 as is done for non-private derived record types.
35264 * sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
35265 Ada 2005 AI-310: an abstract non-dispatching operation is not a
35266 candidate interpretation in an overloaded call.
35268 * tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
35269 expression is Null and target type is not an access type (e.g. a

35274 * exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
35275 statement whose right-hand side is an inlined call, save a copy of the
35276 original assignment subtree to preserve enough consistency for
35277 Analyze_Assignment to proceed.
35279 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35280 complete assignment subtree which is now unnecessary, as the expansion
35281 of inlined call has been improved to preserve a consistent assignment
35282 tree. Note_Possible_Modification must be called only
35283 after checks have been applied, or else unnecessary checks will
35286 * sem_util.adb (Note_Possible_Modification): Reorganise the handling
35287 of explicit dereferences that do not Come_From_Source:
35288 - be selective on cases where we must go back to the dereferenced
35289 pointer (an assignment to an implicit dereference must not be
35290 recorded as modifying the pointer);
35291 - do not rely on Original_Node being present (Analyze_Assignment
35292 calls Note_Possible_Modification on a copied tree).
35294 * sem_warn.adb (Check_References): When an unset reference to a pointer
35295 that is never assigned is encountered, prefer '<pointer> may be null'
35296 warning over '<pointer> is never assigned a value'.

35365 a string literal, create a temporary for it, constant folding only
35366 handles scalars here.
35368 2004-04-01 Vincent Celier <celier@gnat.com>

35552 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35554 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35555 current unit cannot be inlined if it appears in the body of a withed
35556 unit, to avoid order of elaboration problems in gigi.
35558 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35559 information for protected (wrapper) operation as well, to simplify gdb
35562 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35563 protected body, indicate that the entity for the generated spec comes

35605 a classwide type (for which Is_Object_Reference holds), but it can
35606 also be a value conversion for an access-to-classwide type. In the
35607 latter case, there is an implicit dereference, and the original node
35608 for the prefix does not verify Is_Object_Reference.

35688 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35689 declaration for a child subprogram body that acts as a spec, indicate
35690 that the entity in the declaration needs debugging information.
35692 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35693 full view if the subtype is created for a constrained record component;
35694 gigi has enough information to construct the record, and there is no
35695 place in the tree for the declaration.
35697 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35698 serial number for the dummy body that is built for analysis, to avoid
35699 inconsistencies in the generation of internal names when compiling
35702 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35704 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35707 2004-03-22 GNAT Script <nobody@gnat.com>
35709 * Make-lang.in: Makefile automatically updated
35711 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

35738 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35740 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35741 as regular exception objects and not as mere integers representing the
35742 condition code. The latter approach required some dynamics to mask off
35743 severity bits, which did not fit well into the GCC table based model.
35744 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35745 exception data objects. We don't it and it would conflict with the other
35746 external symbol we have to generate for such exceptions.
35748 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35749 the special code for VMS exceptions, since these are now represented
35750 as regular exceptions objects.
35752 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35754 * decl.c (debug_no_type_hash): Remove.

35758 2004-03-19 Laurent Guerby <laurent@guerby.net>
35760 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35761 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35763 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35765 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.

35790 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35792 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35793 When needed (stack checking) the stack size is retrieved
35794 from the VxWorks kernel.
35796 * Makefile.in: Flag -nostdinc is required when building the run time
35797 for avoiding looking for files in the base compiler.
35798 Add the VxWorks specific version of the package body for
35799 System.Stack_checking.Operations (5zstchop.adb).
35801 * Make-lang.in: Add the object file for
35802 System.Stack_Checking.Operations.

35810 checking from this package to package System.Stack_Checking.Operations.
35811 This way, stack checking operations are only linked in the final
35812 executable when using the -fstack-check flag.
35814 2004-03-18 Doug Rupp <rupp@gnat.com>
35816 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35826 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35827 the procedures Add_To_Path_File.
35828 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35829 making sure that each directory is present only once and, for object
35830 dirs, when a directory already present is added, the duplicate is
35831 removed and the directory is always put as the last in the table.
35832 Write the path files at the end of these accumulations.
35834 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35835 Files_Htable for all sources.
35837 * prj-proc.adb (Process): Remove restrictions between not directly
35838 related extending projects.

35846 parameter Trusted_Mode.
35848 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35850 * scn.adb (Determine_License): Take into account a degenerated case
35851 when the source contains only comments.
35853 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35855 * sem_warn.adb (Check_References): For a warning on a selected
35856 component that does not come from source, locate an uninitialized
35857 component of the record type to produce a more precise error message.
35859 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35861 * 3zsoccon.ads: Fix multicast options.
35863 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35866 2004-03-15 Robert Dewar <dewar@gnat.com>

35869 pragma used for a private type.
35871 * lib-xref.adb (Generate_Reference): Do not generate warning if
35872 reference is in a different unit from the pragma Unreferenced.

35878 flag if we have an unchecked conversion to an access type in the same
35881 2004-03-15 Geert Bosch <bosch@gnat.com>
35883 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35884 imaginary parts, use Double precision throughout.
35886 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35887 we want to be able to compile run-time with -gnata for testing, but
35888 this may also be instantiated in user code that is compiled with -gnata.
35890 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35892 * s-stalib.ads (Exception_Code): New type, to represent Import/Export

35894 throughout the various run-time units.
35895 (Exception_Data): Use Exception_Code for Import_Code.
35897 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of

35905 component, now reflected by an exported accessor.
35906 (is_handled_by): New routine to compute whether the propagated
35907 occurrence matches some handler choice specification. Extracted out of
35908 get_action_description_for, and expanded to take care of the VMS
35910 (get_action_description_for): Use is_handled_by instead of an explicit
35911 complex condition to decide if the current choice at hand catches the
35912 propagated occurrence.
35914 * raise.h (Exception_Code): New type for C.
35916 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35917 System.Standard_Library.Exception_Code, to allow references from the
35918 pragma import/export expander.
35920 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35921 New accessors to allow easy access to GNAT exception data
35923 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35924 redundant Handled_By_Others component, helper for the personality
35925 routine which will now be able to call the appropriate exception data
35928 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35929 component of Standard_Exception_Type to be the closest possible to
35930 Exception_Code in System.Standard_Library, that we cannot get at this
35931 point. Expand a ??? comment to notify that this type node should
35932 probably be rewritten later on.
35934 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35935 registration call to include a pointer to the exception object in the
35938 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In

35941 2004-03-15 Vincent Celier <celier@gnat.com>
35943 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35944 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35946 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35947 longer needed now that it is in the spec of
35948 System.Tasking.Task_Attributes.
35950 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35952 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35954 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35956 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35957 taken care of in Scan_Make_Arg.
35958 (Scan_Make_Arg): Add the executable suffix only if the argument
35959 following -o, in canonical case, does not end with the executable
35960 suffix. When in verbose mode and executable file name does not end
35961 with executable suffix, output the executable name, in canonical case.
35963 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35964 to avoid warnings when instantiating Ada.Task_Attributes.
35967 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35968 in the correct order.
35970 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but

35980 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35981 tagged type is inherited, and the parent operation is not frozen yet,
35982 force generation of a freeze node for the inherited operation, so the
35983 corresponding dispatch entry is properly initialized.
35984 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35985 when looking for user-defined equality operation.
35987 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35988 boolean when locating primitive equality of tagged component.
35990 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a

35992 a temporary before expanding assignment into a loop.
35994 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35995 priority in full, to ensure that any expanded subepxressions of it are
35996 elaborated in the scope of the init_proc.
35998 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35999 after object declaration, skipping over code that may have been
36000 generated for validity checks.
36002 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36003 discriminants, ignore the known discriminants of its full view, if
36004 any, to check legality.
36006 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36007 component if type has unknown discriminants.
36008 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36009 null if type has unknown discriminants.
36011 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36012 for end label when present.
36014 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36015 temporary file, rather than an empty string.
36017 2004-03-15 Ed Falis <falis@gnat.com>
36019 * s-thread.adb: Removed, no longer used.

36041 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36042 Insert_Dereference_Action when rewriting an implicit dereference into
36043 an explicit one, this will be taken care of during expansion of the
36044 explicit dereference.
36045 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36046 of non-packed slices, since the dereference action generated by
36047 expansion of the explicit dereference is needed in any case.
36048 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36049 analyze and resolve the rewritten explicit dereference so it is seen
36051 (Insert_Dereference_Action): This procedure is now called only for the
36052 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36053 dereferences that do not come from source (including explicit
36054 dereferences resulting from rewriting implicit ones), but do not
36055 recursively insert a check for the dereference nodes contained within
36057 (Insert_Dereference_Action): Clarify and correct comment.

36934 checks for bitfield creation are triggered.
36935 (finish_record_type): During last pass over the fields, clear
36936 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37278 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
37279 generated to rename a generic actual, go to the actual itself, the
37280 subtype is not a user-visible entity.
37282 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible
37283 part is a private subtype, reset the visibility of its full view, if
37284 any, to be consistent.
37287 * sem_ch12.adb (Analyze_Formal_Package): Diagnose properly an attempt
37288 to use a generic package G as a formal package for another generic
37291 2004-01-12 Robert Dewar <dewar@gnat.com>

37320 2004-01-05 Robert Dewar <dewar@gnat.com>
37322 * 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
37323 be modified by the binder generated main program if the -D switch is
37326 * 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
37327 imported functions (since now we expect this to be done for imported
37330 * 5vtaprop.adb: Add several ??? for sections requiring more comments
37331 Minor reformatting throughout
37333 * 5zinit.adb: Minor reformatting
37334 Add 2004 to copyright date
37335 Minor changes to avoid -gnatwa warnings
37336 Correct some instances of using OR instead of OR ELSE (noted while
37337 doing reformatting)
37339 * sprint.adb: Minor updates to avoid -gnatwa warnings
37341 * s-secsta.ads, s-secsta.adb:
37342 (SS_Get_Max): New function to obtain high water mark for ss stack
37343 Default_Secondary_Stack is not a constant since it may be modified by
37344 the binder generated main program if the -D switch is used.
37346 * switch-b.adb: New -Dnnn switch for binder
37349 Make -gnatg imply all warnings currently in -gnatwa
37351 * vms_conv.adb: Minor reformatting
37352 Add 2004 to copyright notice

37375 lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
37376 Minor reformatting and code clean ups.
37377 Minor changes to prevent -gnatwa warnings
37379 * ali.adb: Minor reformatting and cleanup of code
37380 Acquire new SS indication of secondary stack use from ali files
37382 * a-numaux.ads: Add Pure_Function pragmas for all imported functions
37383 (since now we expect this to be done for imported functions)
37385 * bindgen.adb: Generate call to modify default secondary stack size if
37388 * bindusg.adb: Add line for new -D switch
37390 * exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
37391 replacement name for Type_May_Have_Non_Bit_Aligned_Components!
37392 Add circuitry for both records and arrays to avoid gigi
37393 processing if the type involved has non-bit-aligned components
37395 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37396 N_String_Literal node always references an E_String_Literal_Subtype
37397 entity. This may not be true in the future.
37398 (Possible_Bit_Aligned_Component): Move processing of
37399 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37401 * exp_ch6.adb (Expand_Thread_Body): Pick up
37402 Default_Secondary_Stack_Size as variable so that we get value modified
37403 by possible -Dnnn binder parameter.
37405 * exp_util.adb (Component_May_Be_Bit_Aligned): New function.
37406 (Type_May_Have_Bit_Aligned_Components): New function.
37408 * exp_util.ads (Component_May_Be_Bit_Aligned): New function.

37416 importing constant atomic/volatile objects.
37417 (Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
37418 unless explicit Pure_Function pragma given, to avoid insidious bug of
37419 call to non-pure imported function getting eliminated.

37422 gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
37423 gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting

37437 New switch Sec_Stack_Used (GNAT, GNATBIND)
37438 Make Default_Secondary_Stack_Size a variable instead of a constant,
37439 so that it can be modified by the new -Dnnn bind switch.
37441 * rtsfind.adb (Load_Fail): Give full error message in configurable
37442 run-time mode if all_errors mode is set. This was not done in the case
37443 of a file not found, which was an oversight.
37444 Note if secondary stack unit is used by compiler.
37446 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37447 ineffective elaborate all pragmas on non-visible packages (this
37448 happened when a renamed subprogram was called). Now the elaborate all
37449 always goes on the package containing the renaming rather than the one
37450 containing the renamed subprogram.
37452 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37453 (Process_Eliminate_Pragma): Add parameter to capture pragma location.
37455 * sem_eval.adb (Eval_String_Literal): Do not assume that string literal
37456 has an Etype that references an E_String_Literal.
37457 (Eval_String_Literal): Avoid assumption that N_String_Literal node
37458 always references an E_String_Literal_Subtype entity. This may not
37459 be true in the future.
37461 * sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
37464 * sem_res.adb (Resolve): Specialize msg for function name used in proc
37467 2004-01-05 Ed Falis <falis@gnat.com>
37469 * g-debuti.adb: Replaced direct boolean operator with short-circuit
37472 2004-01-05 Vincent Celier <celier@gnat.com>
37474 * bld.adb: Minor comment updates
37475 (Process_Declarative_Items): Correct incorrect name (Index_Name instead
37478 * make.adb (Gnatmake): Special process for files to compile/check when
37479 -B is specified. Fail when there are only foreign mains in attribute
37480 Main of the project file and -B is not specified. Do not skip bind/link
37481 steps when -B is specified.
37483 * makeusg.adb: Document new switch -B
37485 * opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag
37487 * switch-m.adb: (Scan_Make_Switches): Process -B switch
37489 * vms_data.ads: Add new GNAT PRETTY qualifier

37494 * trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
37497 * misc.c (gnat_printable_name): If VERBOSITY is 2, call
37498 Set_Identifier_Casing.
37500 * decl.c (gnat_to_gnu_entity, E_Function): Give error if return type
37501 has size that overflows.
37503 2004-01-05 Gary Dismukes <dismukes@gnat.com>
37505 * exp_ch4.adb (Expand_Array_Comparison): Add Boolean constant to avoid
37506 -gnatwa warning on static condition.
37508 2004-01-05 Doug Rupp <rupp@gnat.com>
37510 * link.c: (shared_libgnat_default) [VMS]: Change to STATIC.
37512 2004-01-05 Arnaud Charlet <charlet@act-europe.fr>
37514 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37515 all attributes, including read-only attribute.
37517 2004-01-05 Pascal Obry <obry@gnat.com>
37519 * bindgen.adb (Gen_Object_Files_Options): Generate the new shared
37520 library naming scheme.
37522 * mlib-prj.adb (Build_Library): Generate different names for the static
37523 or dynamic version of the GNAT runtime. This is needed to support the
37524 new shared library naming scheme.
37525 (Process_Binder_File): Add detection of shared library in binder file
37526 based on the new naming scheme.
37528 * gnatlink.adb (Process_Binder_File): Properly detect the new naming
37529 scheme for the shared runtime libraries.
37532 (LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
37534 (install-gnatlib): Do not create symlinks for shared libraries.
37535 (gnatlib-shared-default): Idem.
37536 (gnatlib-shared-dual-win32): New target. Not used for now as the
37537 auto-import feature does not support arrays/records.
37538 (gnatlib-shared-win32): Do not create copy for the shared libraries.
37539 (gnatlib-shared-vms): Fix shared runtime libraries names.
37541 * osint.ads, osint.adb (Shared_Lib): New routine, returns the target
37542 dependent runtime shared library name.
37544 2004-01-05 Vasiliy Fofanov <fofanov@act-europe.fr>
37546 * osint.adb (Read_Library_Info): Remove bogus check if ALI is older
37549 2004-01-05 Ed Schonberg <schonberg@gnat.com>
37551 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
37552 protected objects when allocator has a subtype indication, not a
37553 qualified expression. Note that qualified expressions may have to be
37554 checked when limited aggregates are implemented.
37556 * sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
37557 pure, emit warning.
37558 (Analyze_Pragma, case Pure_Function): If enclosing package is pure and
37559 subprogram is imported, remove warning.
37561 2004-01-05 Geert Bosch <bosch@gnat.com>
37563 * s-poosiz.adb: Update copyright notice.
37564 (Allocate): Use Task_Lock to protect against concurrent access.
37565 (Deallocate): Likewise.
37567 2004-01-05 Joel Brobecker <brobecker@gnat.com>
37569 * s-stalib.adb (Elab_Final_Code): Add missing year in date inside ???

37599 Ada.Exceptions.Last_Chance_Handler.
37601 2003-12-17 Sergey Rybin <rybin@act-europe.fr>
37603 * cstand.adb (Create_Standard): Change the way how the declaration of
37604 the Duration type is created (making it the same way as it is for all
37605 the other standard types).
37607 2003-12-17 Robert Dewar <dewar@gnat.com>
37609 * s-crtl.ads: Fix header format
37610 Change Pure to Preelaborate
37612 2003-12-17 Ed Schonberg <schonberg@gnat.com>
37614 * checks.adb (Selected_Length_Checks): Generate an Itype reference for
37615 the expression type only if it is declared in the current unit.
37617 * sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
37618 are universal and already analyzed, as can occur in constrained
37619 subcomponents that depend on discriminants, when one constraint is a
37622 * sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
37623 type Any_Fixed is legal as the argument of a conversion, if only one
37624 fixed-point type is in context.
37626 2003-12-17 GNAT Script <nobody@gnat.com>

37635 2003-12-15 Vincent Celier <celier@gnat.com>
37637 * gnatchop.adb: (Error_Msg): Do not exit on error for a warning
37638 (Gnatchop): Do not set failure status when reporting the number of
37641 2003-12-15 Doug Rupp <rupp@gnat.com>
37643 * s-ctrl.ads: New file.
37645 * Makefile.rtl (GNAT_RTL_NONTASKING_OBJS): Add s-crtl$(objext).
37647 * Make-lang.in: (GNAT_ADA_OBJS): Add ada/s-crtl.o.
37648 (GNATBIND_OBJS): Add ada/s-crtl.o.

37663 * Make-lang.in: Makefile automatically updated
37665 2003-12-11 Ed Falis <falis@gnat.com>
37667 * 5zinit.adb: Clean up.
37669 * 5zintman.adb (Notify_Exception): replaced case statement with a call
37670 to __gnat_map_signal, imported from init.c to support
37671 signal -> exception mappings that depend on the vxWorks version.
37674 Created and exported __gnat_map_signal to support signal -> exception
37675 mapping that is dependent on the VxWorks version.

37685 __gnat_handler_installed, as done on all other platforms.
37686 Remove duplicated code.
37688 2003-12-11 Jerome Guitton <guitton@act-europe.fr>
37690 * Makefile.in (rts-zfp, rts-ravenscar): Create libgnat.a.
37692 2003-12-11 Thomas Quinot <quinot@act-europe.fr>
37694 * sinfo.ads: Fix inconsistent example code in comment.
37696 2003-12-11 Robert Dewar <dewar@gnat.com>
37698 * a-tiinau.adb: Add a couple of comments
37700 * sem_ch3.adb: Minor reformatting
37703 Fix bad prototype of Same_Base_Type in body (code reading cleanup)
37704 Minor reformatting throughout
37706 2003-12-11 Ed Schonberg <schonberg@gnat.com>
37708 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37709 bounds of a loop, create a separate block in order to generate proper
37710 cleanup actions to prevent memory leaks.
37712 * sem_res.adb (Resolve_Call): After a call to
37713 Establish_Transient_Scope, the call may be rewritten and relocated, in
37714 which case no further processing is needed.
37716 * sem_util.adb: (Wrong_Type): Refine previous fix.
37717 Fixes ACATS regressions.
37720 * sem_prag.adb (Back_End_Cannot_Inline): A renaming_as_body can always
37723 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
37725 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
37726 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
37729 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
37732 2003-12-08 Robert Dewar <dewar@gnat.com>
37734 * 7sintman.adb: Minor reformatting
37736 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37737 standard linker options to get standard libraries linked. We now plan
37738 to provide dummy versions of these libraries to match the appropriate
37739 configurable run-time (e.g. if a library is not needed at all, provide
37740 a dummy empty library).
37742 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37743 options (-L parameters and standard libraries). What we plan to do is
37744 to provide dummy libraries where the libraries are not required.
37746 * gnatbind.adb: Minor comment improvement
37748 2003-12-08 Javier Miranda <miranda@gnat.com>
37750 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37751 aggregate in the parent. Otherwise constants with limited aggregates
37752 are not supported. Add new formal to pass the component type (Ctype).
37753 It is required to call the corresponding IP subprogram in case of
37754 default initialized components.
37755 (Gen_Assign): In case of default-initialized component, generate a
37756 call to the IP subprogram associated with the component.
37757 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37758 of aggregate with default initialized components.
37759 (Has_Default_Init_Comps): Improve implementation to recursively check
37760 all the present expressions.
37762 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37763 to indicate that the initialization call corresponds to a
37764 default-initialized component of an aggregate.
37765 In case of default initialized aggregate with tasks this parameter is
37766 used to generate a null string (this is just a workaround that must be
37767 improved later). In case of discriminants, this parameter is used to
37768 generate a selected component node that gives access to the discriminant
37771 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37772 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37773 allocated aggregates with default-initialized components.
37775 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37776 the box notation is used in positional aggregates.
37778 2003-12-08 Samuel Tardieu <tardieu@act-europe.fr>
37780 * lib.ads: Fix typo in comment
37782 2003-12-08 Vincent Celier <celier@gnat.com>
37784 * prj.adb (Project_Empty): New component Unkept_Comments
37785 (Scan): Remove procedure; moved to Prj.Err.
37787 * prj.ads (Project_Data): New Boolean component Unkept_Comments

39526 (__gnat_full_name) [sgi] Return buffer.
39528 2003-10-22 Arnaud Charlet <charlet@act-europe.fr>
39530 * mingw32.h: New file.
39531 * gnat_wrapper.adb: New file.
39533 2003-10-22 Jerome Roussel <roussel@act-europe.fr>
39535 * g-regpat.ads, g-regpat.adb (Match): new function, to know if a
39536 string match a pre compiled regular expression (the corresponding
39537 version of the function working on a raw regular expression)
39538 Fix typos in various comments
39539 Update copyright notice in spec
39541 2003-10-21 Gary Dismukes <dismukes@gnat.com>
39544 (Component_Needs_Simple_Initialization): Return False when the type is a
39545 packed bit array. Revise spec comments to document this case.
39548 (Expand_Pragma_Import): Set any expression on the imported object to
39549 empty to avoid initializing imported objects (in particular this
39550 covers the case of zero-initialization of bit arrays).
39551 Update copyright notice.
39553 2003-10-21 Ed Schonberg <schonberg@gnat.com>
39556 (Load_Parent_Of_Generic): If parent is compilation unit, stop search,
39557 a subunit is missing.
39558 (Instantiate_Subprogram_Body): If body of function is missing, set type
39559 of return expression explicitly in dummy body, to prevent cascaded
39560 errors when a subunit is missing.
39564 (Access_Subprogram_Declaration): Verify that return type is valid.
39568 (Check_Elab_Calls): Do not apply elaboration checks if the main unit is
39573 (Corresponding_Discriminant): If the scope of the discriminant is a
39574 private type without discriminant, use its full view.

41581 (general) Add @./@: where approriate, and two spaces after the
41582 full stop at the end of a sentence. Use @samp markup when
41583 referring concrete lexical entities (keywords, attribute names
41584 etc.), and @syntax for ARM grammar elements. Use @r for English

41599 * make.adb (Add_Switch): Make Generic_Position a procedure. The
41600 function approach did not work well because of a side effect (the
41601 function call could reallocate the table which was being indexed
41602 using its result). Fixes ada/4851.

41661 Add 2001 to copyright date
41663 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41664 need to force universal inlining for these cases.

41880 When using a project file, fail if specified executable is relative
41881 path with directory information, and prepend executable, if not

41967 to Hbound, but no actual example of failure has been found.
41969 2001-12-17 Laurent Pautet <pautet@gnat.com>
41972 Fix comment of Shutdown_Socket and Close_Socket. These functions
41973 should not fail silently because if they are called twice, this
41974 probably means that there is a race condition in the user program.
41975 Anyway, this behaviour is consistent with the rest of this unit.
41976 When an error occurs, an exception is raised with the error message
41977 as exception message.
41979 2001-12-17 Robert Dewar <dewar@gnat.com>

43311 instead of the previous simple checksum algorithm.
43312 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43313 (Set_Source_Table): idem.
43316 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43317 instead of simple checksum.
43318 (CRC_Match): new function.
43319 (CRC_Error): new constant.
43321 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43322 a CRC now and not a simple checksum. A CRC uses lower-case hex
43323 letters, fixes ambiguity in parsing.
43325 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43326 is what this variable will store.
43328 * bcheck.adb: Change reference to chechsum in comments by CRC.
43329 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43330 rename All_Checksum_Match to All_CRC_Match. Change due to API
43331 renaming since now GNAT does not use a simple checksum but a
43332 CRC using GNAT.CRC32.
43334 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43335 now and not anymore a simple checksum.

43372 Update comments for the CRC.
43374 * types.adb (Hex): Use lowercase for the letter part.
43376 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43377 for a word. This is currently used only for CRC. In previous version,
43378 the checksum was using a representation with all letter being
43379 upper-case. With the new implementation (using CRC) we do not remove
43380 the 32th bit of the CRC, so we can have an upper-case starting letter
43381 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43382 It is ambigous since the CRC was optional and could be followed by
43383 options like EB, EE. So now this routines uses lower-case letter for
43384 the hexadecimal representation. Strange enough only lower case letters
43385 where checked in Scan_ALI (even if this was not a possible case).
43387 * gnatvsn.ads (Library_Version): changed to 3.15a.
43389 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43392 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
