1776 conversions of the class-wide return object to the specific type on
1777 component assignments).

1780 about a type mismatch for a class-wide function with a return object
1781 having a specific type when the object declaration doesn't come from

2104 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2105 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4197 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4200 (Freeze_Enumeration_Type): For a subtype that inherits a foreign
4201 convention from its base type, do not set the type to that of integer,

4244 (P_Access_Definition): Change the error message when parsing "access
4245 all" in Ada 95 mode. The message no longer forces the user to recompile

4266 the visible part of the spec of a remote types unit.

4268 New local subprogram Is_Valid_Remote_Object_Type, replaces
4269 Is_Recursively_Limited_Private.
4270 (Validate_RACW_Primitives): Enforce E.2.2(14) rules: the types of all
4271 non-controlling formals (and the return type, even though this is not
4272 explicit in the standard) must support external streaming.
4273 (Validate_RCI_Subprogram_Declaration): Enforce E.2.3(14) rules: same
4274 as above for of RAS types and RCI subprograms. (The return type is not

4279 * sem_util.ads, sem_util.adb
4280 (Is_Remote_Access_To_Class_Wide_Type): Only rely on Is_Remote_Types and
4281 Is_Remote_Call_Interface to identify RACW types in a stable and
4282 consistent way. We used to rely in this predicate on the privateness of
4283 the designated type and its ancestors, but depending on the currently
4284 visible private parts, this caused false negatives. We now uniformly
4285 rely on checks made at the point where the RACW type is declared.

4298 completed with pragma Import.
4299 Add missing escaping of all-caps word 'CPP' in error messages.
4300 (Build_Discriminated_Subtype): Do not inherit representation clauses
4301 from parent type if subtype already carries them, because they are
4302 inherited earlier during derivation and already include those that may
4303 come from a partial view.
4305 * sem_ch9.adb, sem_ch5.adb, sem_ch6.adb (Analyze_Subprogram_Body):
4306 Check the declarations of a subprogram body for proper deferred

4340 (Add_One_Interp): Ignore any interpretation that is a primitive
4341 operation of an RACW stub type (these primitives are only executed
4342 through dispatching, never through static calls).
4343 (Collect_Interps): When only one interpretation has been found, set N's
4344 Entity and Etype to that interpretation, otherwise Entity and Etype may
4345 still refer to an interpretation that was ignored by Add_One_Interp,
4346 in which case would end up with being marked as not overloaded but with
4347 an Entity attribute not pointing to its (unique) correct interpretation.
4349 2008-05-20 Ed Schonberg <schonberg@adacore.com>
4352 (Eval_Slice): Warn when a slice whose discrete range is a subtype name

4362 (Print_Itype): Do not modify the sloc of the component type of a
4363 (packed) array itype, because it is an unrelated type whose source
4364 location is independent of the point of creation of the itype itself.

4403 2008-05-20 Arnaud Charlet <charlet@adacore.com>
4405 * s-winext.ads: Replace representation clause by pragma Pack. Gives
4406 equivalent representation, but has the advantage of allowing
4407 compilation of this file under 64 bits platforms.
4409 * s-os_lib.adb (Normalize_Pathname): Mark Cur_Dir constant.
4411 * s-osinte-irix.ads: (Alternate_Stack_Size): Add dummy declaration.

8607 WITH clause on a private sibling.
8608 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8609 child unit is a renaming, create an implicit with_clause on that

8712 perform subtype conformance between the formals of the current entry
8713 and those of the target interface primitive.
8714 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8715 Timed_Entry_Call): Analyze the triggering statement as the first step of
8716 the processing. If this is a dispatching select, postpone the analysis
8717 of all select statements until the Expander transforms the select. This

8719 replicated some of the select statements. In case the Expander is
8720 disabled, perform regular analysis.
8721 (Check_Triggering_Statement): New routine.
8722 (Analyze_Requeue): Exclude any interpretations that are not entries when
8723 checking overloaded names in a requeue. Also test type conformance for

8732 for the defaulted actual.
8734 2007-12-13 Geert Bosch <bosch@adacore.com>
8736 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9319 multiple inherited interfaces info. This information cannot be stored
9320 in Xref_Entity_Record, which only supports a single instance of Tref_*,

9340 that handles use of 'Access and 'Unchecked_Access applied to

9412 Runtime_Library_Dir.
9414 * prj-part.adb (Parse_Single_Project): Do not check the name of the
9415 config project against the user project names.
9417 * prj-proc.adb (Expression): In multi-language mode, indexes that do
9418 not include a dot are always case insensitive.
9419 (Process_Declarative_Items): Ditto
9420 (Process_Project_Tree_Phase_1): Set Success to False in case an error is
9423 * prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is
9424 True, compare both indexes in lower case.

9430 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9432 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9433 association for an access component, add an association with null as
9434 the expression. Remove testing for array subtypes and the setting in
9435 that case of Ctyp to the array component type, which prevented proper
9436 inclusion of an association for null-initialized arrays. Collapse
9437 condition that tests for array subtypes into just a test of
9438 Is_Partially_Initialized_Type (which already covers arrays anyway).
9440 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>

9455 * sem_ch4.adb: Minor code and comment reformatting.
9456 (Analyze_Allocator): When the designated type of an unconstrained
9457 allocator is a record with unknown discriminants or an array with
9458 unknown range bounds, emit a detailed error message depending on the
9459 compilation mode and whether the designated type is limited.

9582 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
9584 Mapped location support
9585 * back_end.adb (Call_Back_End): Pass information about source
9586 files instead of units to gigi.
9587 * gigi.h (struct File_Info_Type): New.
9588 (gigi): Rename and change type of number_units parameter, change
9589 type of file_info_ptr parameter.
9590 * trans.c (number_files): New global variable.
9591 (gigi): Rename and change type of number_units parameter, change
9592 type of file_info_ptr parameter.
9593 If mapped location support is enabled, create the isomorphic mapping
9594 between source files and line maps.
9595 (Sloc_to_locus): If mapped location support is enabled, translate
9596 source location into mapped location.
9597 (annotate_with_node): Rename into set_expr_location_from_node.

9623 * a-calend-vms.adb, a-calend.adb:
9624 Add a section on leap seconds control along with two entities used to
9625 enable and disable leap seconds support. The array Leap_Second_Times is
9626 now constant and contains hard time values pre-generated. Remove
9627 all elaboration code used to populate the table of leap seconds.
9630 Add entity Leap_Seconds_Support to the list of global run-time variables
9631 along with a comment on its usage and values.
9632 (Gen_Adainit_Ada): Add code to generate the declaration and import of
9633 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
9634 or one (enabled) depending on the presence of binder switch "-y".
9635 (Gen_Adainit_C): Add code to generate the declaration of external int
9636 __gl_leap_seconds_support. Set is value to zero (disabled) or one
9637 (enabled) depending on the presence of binder switch "-y".

9647 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
9649 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
9651 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
9652 function which can be called by the debugger to interrupt the tasks of
9653 an Ada application asynchronously, as needed on VxWorks.
9654 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
9656 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,

9673 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
9675 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9678 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9680 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
9683 * sem_dist.ads: Minor comment fix
9685 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
9687 2007-09-26 Javier Miranda <miranda@adacore.com>
9688 Eric Botcazou <ebotcazou@adacore.com>
9691 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9692 indirection added to the HT_Link component of the TSD. This is required
9693 to statically allocate the TSD.
9696 Minor reordering of the declarations in the private part. Required to
9697 add a level of indirection to the contents of the TSD component HT_Link.
9698 This is required to statically allocate the TSD.
9700 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
9701 Is_Statically_Allocated set from constant objects.
9702 Do not make exported constants created by the compiler volatile.
9703 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
9706 * trans.c (Identifier_to_gnu): For constants, unshare initializers
9707 before returning them.
9709 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
9710 public part of the package.
9711 (Make_DT): Move HT_Link component out of the TSD record. For this
9712 purpose Make_DT now declares a separate object that stores the
9713 HT_Link value, and initializes the TSD component with the address
9714 of this new object. The addition of this level of indirection is
9715 required to statically allocate the TSD because the TSD cannot
9716 have variable components.
9717 (Expand_Interface_Conversion): Improve the expanded code.
9718 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9720 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9721 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9722 if we are building static dispatch tables then we must not generate
9723 extra code to register the primitive because the dispatch table will
9724 be built at the end of the library package; otherwise we notify that
9725 we cannot build the static dispatch table.
9727 2007-09-26 Robert Dewar <dewar@adacore.com>
9729 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

9744 for thunks associated with interface types.
9746 * einfo.ads: Improve documentatation of Is_Internal
9747 (Is_Thunk): New attribute applicable to subprograms. True for thunks
9748 associated with interface types.
9749 Extensive comment fixes regarding flags that appear in all entities. The
9750 documentation is now consistent for all such flags (there were a number
9751 of errors in the documentation in this regard).
9753 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9755 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9756 of these procedures are passed a function call that already has
9757 build-in-place actuals (testing new flag
9758 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9759 the case where processing continues.
9760 (Expand_Call): If the call is generated from a thunk body then we
9761 propagate the extra actuals associated with the accessibility
9762 level of the access type actuals.
9764 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9765 of each extra formal of a protected operation to reference the
9766 corresponding extra formal of the subprogram denoted by the
9767 operation's Protected_Body_Subprogram.
9769 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9770 N_Function_Call nodes.
9772 2007-09-26 Robert Dewar <dewar@adacore.com>
9774 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
9776 * debug.adb: Add d.s flag.
9778 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9780 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
9781 debug variable so that it won't be initialized when pragma
9782 Initialize_Scalars is in effect.
9784 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9786 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9787 initialization of a full view. This is moved to
9788 Analyze_Package_Specification.
9790 * sem_ch7.adb (Analyze_Package_Specification): Add check for
9791 preelaborable initialization of a full view in entity loop.
9792 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9793 its child units are use-visible only if they are visible child units.
9795 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9796 whether an expression can be used within a type declaration that
9797 requires preelaborable init.
9798 (Check_Components): Replace inline code that does partial checking for
9799 preelaborable default expressions with call to
9800 Is_Preelaborable_Expression.
9801 (Has_Preelaborable_Initialization): In the case of a generic actual
9802 subtype, (that is, Is_Generic_Actual is True), return the result of
9803 applying Has_Preelaborable_Initialization to the generic actual's base
9806 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9808 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9809 call to Jan_1_Day _Of_Week to optimize its performance.
9810 (Is_Leap): Move the routine to the scope of Week_In_Year.
9811 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9812 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9813 avoids calling Time_Of and Split, thus making it more efficent.
9814 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9816 * g-calend.ads (Week_In_Year): Change comment to reflect new
9819 2007-09-26 Emmanuel Briot <briot@adacore.com>
9821 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9822 Command_Line): New types
9823 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9824 support for defining how switches can be grouped on a command line (as
9825 is the case for -gnatw... for GNAT), and how simple switches can be
9826 used as aliases for more complex switches (-gnatwa is same as
9828 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9829 (Start, Current_*): New subprograms
9830 Added support for parsing an array of strings in addition to the real
9832 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9833 be moved from the body to the private part of the spec.
9834 (*): All subprograms now have an extra parameter with default value to
9835 specify which parser should be used. For backward compatibility, it
9836 defaults to parsing the command line of the application. They were also
9837 modified to properly handle cases where each of the argument does not
9838 start at index 1 (which is always true for Ada.Command_Line, but not
9839 when processing any Argument_List).
9840 (Free): New subprogram
9841 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9842 Argument): New subprograms
9843 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9844 special characters like ':', '=',... are now handled in a single place,
9845 which makes the code more extensible eventually.
9846 (Getopt, Full_Switch): When the switch was returned as part of the
9847 special character '*', make sure it is prepended by the switch character
9848 ('-' in general), so that the application knows whether "foo" or "-foo"
9849 was specified on the command line.
9851 2007-09-26 Florian Villoing <villoing@adacore.com>
9853 * g-dirope.adb (Remove_Dir): In case we are removing directories
9854 recursively, make sure that if an exception is raised during the
9855 processing, the current working directory is reset to its initial
9856 value before propagating the exception.
9858 2007-09-26 Vincent Celier <celier@adacore.com>
9860 * gnatbind.adb: If there are several ALI files specified and there is
9861 a main program to bind, the first ALI is expected to contain the main
9862 subprogram and the names of the binder generated files will be derived
9863 from the first ALI file name.
9864 (Gnatbind): Fix insertion character in invocation of Error_Msg
9866 2007-09-26 Vincent Celier <celier@adacore.com>
9868 * gnatcmd.adb (Check_Files): Do not include sources that have been
9869 removed by attributes Exclude_Source_Files or Locally_Removed_Files.
9871 2007-09-26 Ed Schonberg <schonberg@adacore.com>
9873 * lib-xref.ads, lib-xref.adb: The entry for array types now carries
9874 information about each of its index types, following the type
9875 reference for its component type.
9877 2007-09-26 Vincent Celier <celier@adacore.com>
9879 * make.adb: (Kill): New procedure (__gnat_kill imported)
9880 (Running_Compile, Outstanding_Compiles): Global variables that
9881 were previously local to procedure Compile_Sources.
9882 (Sigint_Intercepted): Send signal SIGINT to all outstanding
9883 compilation processes.
9885 (Gnatmake): If project files are used, create the mapping of all the
9886 sources, so that the correct paths will be found.
9888 * prj-env.ads, prj-env.adb (Create_Mapping): New procedure
9890 2007-09-26 Vincent Celier <celier@adacore.com>
9892 * makeutl.ads (Main_Config_Project): Moved to gpr_util.ads
9894 * prj.ads, prj.adb (Default_Language): Remove function, no longer used
9895 Replace components Compiler_Min_Options and Binder_Min_Options with
9896 Compiler_Required_Switches and Binder_Required_Switches in record
9898 Remove components Default_Language and Config in Project_Tree_Data,
9901 * prj-attr.adb: New attributes Required_Switches (<language>) in
9902 packages Compiler and Binder.
9904 * prj-nmsc.adb: Major rewrite of the processing of configuration
9905 attributes for gprbuild. No impact on GNAT tools.
9907 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
9908 process configuration attributes: this is done in Prj.Nmsc.Check.
9909 (Recursive_Process): Make a full copy of packages inherited from project
9910 being extended, instead of a shallow copy.
9911 (Process_Project_Tree_Phase_1): New procedure
9912 (Process_Project_Tree_Phase_1): New procedure
9913 (Process): Implementation now uses the two new procedures
9915 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
9916 from the project config, not the tree config that no longer exists.
9918 2007-09-26 Vincent Celier <celier@adacore.com>

10247 potentially be called.

10249 body for 'Output when the type is abstract (only the creation of the
10250 body for 'Input is excluded when the type is abstract).

10252 statement, so that False will be returned for TTS_Stream_Input if the
10253 associated tagged type is an abstract extension. Add comments for

10274 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10275 to remove other spurious ambiguities on arithmetic operations involving
10276 literals and addresses, on systems where Address is a visible integer
10277 type, when the operator is called in functional notation.
10278 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10279 is legal when the types match, even if the operation is currently

10410 exceptions never being raised.
10411 (Analyze_Raise_Statement): When analyzing an exception, mark it as being

10432 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10433 occurring in the list of entities to qualify, and do not attempt to
10434 traverse an entity list in that case. Variables associated with
10435 ` library-level package renamings can now occur in the table.

10459 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10460 concatenations of string literals into a single literal, in order to
10461 avoid very deep recursion in the front end, which was causing stack
10464 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10465 string, and the right operand is a string literal (the case of "" &
10466 "..."), optimize by avoiding copying the right operand -- just use the
10467 value of the right operand directly.
10469 * stringt.adb (Store_String_Chars): Optimize by growing the
10470 String_Chars table all at once, rather than appending characters one by
10472 (Write_String_Table_Entry): If the string to be printed is very long,
10473 just print the first few characters, followed by the length. Otherwise,
10474 doing "pn(n)" in the debugger can take an extremely long time.
10476 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10477 Store_String_Char with Store_String_Chars.

10496 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10497 flag, for effiency. It is called when analyzing arithmetic operators
10498 and also for actuals in calls that are universal_integers. The flag is
10499 set for the predefined type address, and for any type or subtype
10502 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10503 Universal_Integer, when the formal is a descendent of address and the
10504 call appears in user code.

10571 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10572 associated with Standard_Debug_Renaming_Type, to be used as the type of
10573 the special variables whose names provide debugger encodings for
10574 renaming declarations.
10576 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10577 (Set_Debug_Renaming_Link): Change to set Node25.

10587 and the entity of the renaming declaration.
10588 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10589 part of the name of a variable that has a Debug_Renaming_Link.
10591 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a

10596 Ed Schonberg <schonberg@adacore.com>
10597 Javier Miranda <miranda@adacore.com>
10599 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10600 ancestor part given by an aggregate to test for an unchecked conversion,
10601 since this can occur in some cases when the ancestor part is a function
10602 call, and we don't want to fall into the recursive call to this
10603 procedure in that case.
10605 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10606 stream attributes on limited types to account for user-specified
10607 attributes as well as whether Input (resp. Output) becomes available
10608 due to Read (resp. Write) being available for the type. Change Boolean
10609 variable to the more accurate name
10610 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10611 double-"not" predicate at beginning of return statement to more
10612 understandable form.
10614 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10615 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10616 in a block statement and use that as the first statement of the
10617 expanded return rather than incorrectly using the handled sequence as
10618 the first statement.
10620 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10621 operation, generate an explicit freeze node for it rather than
10622 generating extra formals, to ensure that gigi has the proper order of
10623 elaboration for anonymous subtypes in the signature of the subprograms.
10624 (Build_In_Place_Formal): Move assertion to beginning of loop.
10625 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion

10628 applied to a function call (occurs for some cases of 'Input).
10630 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10631 2005, generate an extended return statement enclosing the result object
10634 * freeze.adb (Freeze_Record_Type): Extend the current management of
10635 components that are access type with an allocator as default value: add
10636 missing support to the use of qualified expressions of the
10637 allocator (which also cause freezing of the designated type!)
10638 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10639 dispatching operation, since extra formals may be needed by calls to
10640 build-in-place functions (such as stream 'Input).
10642 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10643 formals for 'Constrained and accessibility level in the case of a
10644 predefined dispatching operation.
10646 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10647 point, no need to find the parent node.
10649 2007-08-16 Javier Miranda <miranda@adacore.com>
10651 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10652 and entry barriers.
10654 2007-08-16 Javier Miranda <miranda@adacore.com>
10656 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10657 is not really required and can introduce regression with the debugger.
10658 The original problem is fixed with the patch written for checks.adb.
10660 2007-08-16 Thomas Quinot <quinot@adacore.com>
10662 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

10672 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10673 parameter Including_Non_Switch, defaulted to True. When
10674 Including_Non_Switch is False, options that are not switches and
10675 appear as relative path are not converted to absolute paths.

10691 (Install_Limited_Withed_Unit): Do not install the limited view of
10692 package P if P is reachable through an ancestor chain from package C
10693 and C also has a with clause for P in its body.

10695 (Has_With_Clause): New routine.
10697 2007-08-16 Ed Schonberg <schonberg@adacore.com>
10699 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10700 generic for an enclosing instance is a global reference, even though
10701 its scope is the enclosing instance.

10727 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10728 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10729 the statement which is being resolved comes from a predefined library
10730 unit, all non-predefined library interpretations are skipped.
10731 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10732 but the "&" is user defined, give an error, because the folding would

10736 the parser has folded a long sequence of concatenations of string
10739 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10740 and "JMP_BUF" variables as artificial.

10795 needed for access to concurrent record types generated by the expander.
10796 (Generate_Range_Check): When generating a temporary to capture the

10810 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10811 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10812 tests optimized out.
10814 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10815 (Get_Allocator_Final_List): For the case of an anonymous access type
10816 that has a specified Associated_Final_Chain, do not go up to the
10818 (Expand_N_Type_Conversion): Test for the case of renamings of access
10819 parameters when deciding whether to apply a run-time accessibility
10821 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10822 aggregate code before allocator, and ahead of declaration for
10823 temporary, to prevent access before elaboration when the allocator is
10824 an actual for an access parameter.
10825 (Expand_N_Type_Conversion): On an access type conversion involving an
10826 access parameter, do not apply an accessibility check when the
10827 operand's original node was an attribute other than 'Access. We now
10828 create access conversions for the expansion of 'Unchecked_Access and
10829 'Unrestricted_Access in certain cases and clearly accessibility should
10830 not be checked for those.
10832 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10833 includes a type conversion of a packed component that has been expanded,
10834 recover the original expression for the object, and use this expression
10835 in the post-call assignment statement, so that the assignment is made
10836 to the object and not to a back-end temporary.
10837 (Freeze_Subprogram): In case of primitives of tagged types not defined
10838 at the library level force generation of code to register the primitive
10839 in the dispatch table. In addition some code reorganization has been
10840 done to leave the implementation clear.
10841 (Expand_Call): When expanding an inherited implicit conversion,
10842 preserve the type of the inherited function after the intrinsic
10843 operation has been expanded.
10845 * exp_ch2.ads, exp_ch2.adb
10846 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10847 of an entry formal appearing in an assignment statement does not assign
10849 (Expand_Current_Value): Instead of calling a routine to determine
10850 whether the prefix of an attribute reference should be optimized or
10851 not, prevent the optimization of such prefixes all together.
10853 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10854 component whose prefix is known to be of an access type is an implicit
10855 dereference and does not assign to the prefix.
10857 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10858 Robert Dewar <dewar@adacore.com>
10860 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
10861 itype is visited, make an entry into table to link associated node and
10863 Add comments and correct harmless error in Build_NCT_Hash_Tables
10864 (Array_Aggr_Subtype): Associate each itype created for an index type to
10865 the corresponding range construct, and not to the aggregate itself. to
10866 maintain a one-to-one correspondence between itype and its associated
10867 node, to prevent errors when complex expression is copied.
10868 Fix mishandling of multiple levels of parens
10870 * sem_aggr.adb: Create a limited view of an incomplete type, to make
10871 treatment of limited views uniform for all visible declarations in a
10872 limited_withed package.
10873 (New_Copy_Tree): If hash table is being used and itype is visited,
10874 make an entry into table to link associated node and new itype.
10875 (Resolve_Record_Aggregate): Do not add an others box association for a
10876 discriminated record component that has only discriminants, when there
10877 is a box association for the component itself.
10879 * par-ch4.adb: Fix mishandling of multiple levels of parens
10881 2007-08-14 Robert Dewar <dewar@adacore.com>
10883 * comperr.adb: Fix problem with suppressing warning messages from gigi
10885 * erroutc.ads, erroutc.adb, errout.ads,
10886 errout.adb (Write_Eol): Remove trailing spaces before writing the line
10887 (Write_Eol_Keep_Blanks): New procedure to write a line, including
10888 possible trailing spaces.
10889 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line
10890 Fix problem with suppressing warning messages from back end
10891 Improve handling of deleted warnings
10894 Fix problem with suppressing warning messages from back end

10914 Javier Miranda <miranda@adacore.com>
10915 Gary Dismukes <dismukes@adacore.com>
10917 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
10918 to make treatment of limited views uniform for all visible declarations
10919 in a limited_withed package.
10920 Improve warnings for in out parameters
10921 (Set_Related_Interaface/Related_Interface): Allow the use of this
10922 attribute with constants.
10923 (Write_Field26_Name): Handle attribute Related_Interface in constants.
10924 Warn on duplicate pragma Preelaborable_Initialialization
10926 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
10927 generation of a freezing node to ensure proper management of null
10928 excluding access types in the backend.
10929 (Create_Extra_Formals): Test base type of the formal when checking for
10930 the need to add an extra accessibility-level formal. Pass the entity E
10931 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
10932 originally being done in a couple of cases), to ensure that the
10933 Extra_Formals list gets set on the entity E when the first entity is
10935 (Conforming_Types): Add missing calls to Base_Type to the code that
10936 handles anonymous access types. This is required to handle the
10937 general case because Process_Formals builds internal subtype entities
10938 to handle null-excluding access types.
10939 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10940 functions that need it, even when not marked Requires_Overriding.
10941 Improve warnings for in out parameters
10942 (Analyze_Function_Return): Warn for disallowed null return
10943 Warn on return from procedure with unset out parameter
10944 Ensure consistent use of # in error messages
10945 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
10946 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
10947 the implicit conversion of the expression done for anonymous access
10948 types. This is required to generate the code of the null excluding
10949 check (if required).
10951 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
10952 A formal parameter is never publicly referenceable outside of its body.
10953 (Check_References): For an unreferenced formal parameter in an accept
10954 statement, use the same warning circuitry as for subprogram formal
10956 (Warn_On_Unreferenced_Entity): New subprogram, taken from
10957 Output_Unreferenced_Messages, containing the part of that routine that
10958 is now reused for entry formals as described above.
10959 (Goto_Spec_Entity): New function
10960 (Check_References): Do not give IN OUT warning for dispatching operation
10961 Improve warnings for in out parameters
10962 (Test_Ref): Check that the entity is not undefinite before calling
10963 Scope_Within, in order to avoid infinite loops.
10964 Warn on return from procedure with unset out parameter

10968 Javier Miranda <miranda@adacore.com>
10969 Gary Dismukes <dismukes@adacore.com>
10971 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
10972 (Expand_N_Attribute_Reference): Further unify the handling of the
10973 three forms of access attributes, using common code now for all three
10974 cases. Add a test for the case of applying an access attribute to
10975 an explicit dereference when the context is an access-to-interface
10976 type. In that case we need to apply the conversion to the prefix
10977 of the explicit dereference rather than the prefix of the attribute.
10978 (Attribute_Version, UET_Address): Set entity as internal to ensure
10979 proper dg output of implicit importation.
10980 (Expand_Access_To_Type): Removed.
10981 (Expand_N_Attribute_Reference): Merge the code from the three cases
10982 of access attributes, since the processing is largely identical for
10983 these cases. The substantive fix here is to process the case of a
10984 type name prefix (current instance case) before handling the case
10985 of interface prefixes.

10988 Ed Schonberg <schonberg@adacore.com>
10989 Javier Miranda <miranda@adacore.com>
10990 Robert Dewar <dewar@adacore.com>
10992 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10993 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10994 type that is an anonymous access to controlled object, establish
10995 an associated finalization chain to avoid corrupting the global
10996 finalization list when a dynamically allocated object designated
10997 by such a component is deallocated.
10998 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10999 functions that need it, even when not marked Requires_Overriding.
11000 (Initialize_Tag): Replace call to has_discriminants by call to
11001 Is_Variable_Size_Record in the circuitry that handles the
11002 initialization of secondary tags.
11003 (Is_Variable_Size_Record): New implementation.
11004 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11005 Suppress_Initialization pragma for a derived type.
11006 (Is_Variable_Size_Record): New subprogram.
11007 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11008 initial version of this routine and also fixes problems causing
11009 incomplete initialization of the table of interfaces.
11010 (Build_Init_Procedure): Improve the generation of code to initialize the
11011 the tag components of secondary dispatch tables.
11012 (Init_Secondary_Tags): New implementation that simplifies the previous
11013 version of this routine.
11014 (Make_DT): Add parameter to indicate when type has been frozen by an
11015 object declaration, for diagnostic purposes.
11016 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11017 diagnose attemps to freeze a subprogram when some untagged type of its
11018 profile is a private type whose full view has not been analyzed yet.
11019 (Freeze_Array_Type): Generate init proc for packed array if either
11020 Initialize or Normalize_Scalars is set.
11021 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11022 constructing the new profile, copy the null_exclusion indicator for each
11023 parameter, to ensure full conformance of the new body with the spec.
11025 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11026 Create wrappers for constructor functions that need it, even when not
11027 marked Requires_Overriding.
11028 (Covers): Handle properly designated types of anonymous access types,
11029 whose non-limited views are themselves incomplete types.
11030 (Add_Entry): Use an entity to store the abstract operation which hides
11032 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11033 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11034 initialization aggregate.
11035 (Function_Interp_May_Be_Hidden): Rename to
11036 Function_Interp_Has_Abstract_Op.
11037 (Has_Compatible_Type): Remove machinery that skips interpretations if
11038 they are labeled as potentially hidden by an abstract operator.
11039 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11040 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11041 (Write_Overloads): Output the abstract operator if present.
11042 (Add_Entry): Before inserting a new entry into the interpretation table
11043 for a node, determine whether the entry will be disabled by an abstract
11045 (Binary_Op_Interp_May_Be_Hidden): New routine.
11046 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11048 (Function_Interp_May_Be_Hidden): New routine.
11049 (Has_Compatible_Type): Do not consider interpretations hidden by
11050 abstract operators when trying to determine whether two types are
11052 (Has_Hidden_Interp): New routine.
11053 (Set_May_Be_Hidden_Interp): New routine.
11054 (Write_Overloads): Write the status of flag May_Be_Hidden.

11057 Javier Miranda <miranda@adacore.com>
11059 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
11060 types declared in the declarative part of a nested package body or in
11061 the proper body of a stub.
11062 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11063 of the same dispatch table slot to renamed primitives.
11064 (Make_Select_Specific_Data_Table): Handle private types.
11065 (Tagged_Kind): Handle private types.
11066 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11067 output of implicit importation and exportation.
11068 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11069 first formal of the thunk is always associated with the controlling
11070 type. In addition perform the following code cleanup: remove formal
11071 Thunk_Alias which is no longer required, cleanup evaluation of the
11072 the controlling type, and update the documentation.
11073 Replace occurrence of Default_Prim_Op_Count by
11074 Max_Predef_Prims. Addition of compile-time check to verify
11075 that the value of Max_Predef_Prims is correct.
11076 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11077 (Make_DT): Add parameter to indicate when type has been frozen by an
11078 object declaration, for diagnostic purposes.
11079 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11080 construction of statically allocated dispatch tables.
11081 (Make_DT): In case of library-level tagged types export the declaration
11082 of the primary tag. Remove generation of tags (now done by Make_Tags).
11083 Additional modifications to handle non-static generation of dispatch
11084 tables. Take care of building tables for asynchronous interface types
11085 (Make_Tags): New subprogram that generates the entities associated with
11086 the primary and secondary tags of Typ and fills the contents of Access_
11087 Disp_Table. In case of library-level tagged types imports the forward
11088 declaration of the primary tag that will be declared later by Make_DT.
11089 (Expand_Interface_Conversion): In case of access types to interfaces
11090 replace an itype declaration by an explicit type declaration to avoid
11091 problems associated with the scope of such itype in transient blocks.
11093 2007-08-14 Robert Dewar <dewar@adacore.com>
11094 Ed Schonberg <schonberg@adacore.com>
11095 Javier Miranda <miranda@adacore.com>
11097 * exp_util.ads, exp_util.adb:
11098 This patch replaces a number of occurrences of explicit tests for N_Null
11099 with calls to Known_Null. This improves tracking of null values, since
11100 Known_Null also catches null constants, and variables currently known to
11101 be null, so we get better tracking.
11102 (Ensure_Defined): create an itype reference only in the scope of the
11104 (Side_Effect_Free): A selected component of an access type that
11105 denotes a component with a rep clause must be treated as not
11106 side-effect free, because if it is part of a linked structure its
11107 value may be affected by a renaming.
11108 (Expand_Subtype_From_Expr): For limited objects initialized with build
11109 in place function calls, do nothing; otherwise we prematurely introduce
11110 an N_Reference node in the expression initializing the object, which
11111 breaks the circuitry that detects and adds the additional arguments to
11112 the called function. Bug found working in the new patch for statically
11113 allocated dispatch tables.
11114 (Is_Library_Level_Tagged_Type): New subprogram.
11115 (Remove_Side_Effects): If the expression of an elementary type is an
11116 operator treat as a function call.
11117 (Make_Literal_Range): If the index type of the array is not integer, use
11118 attributes properly to compute the constraint on the resulting aggregate
11121 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11122 class-wide type whose base type is an incomplete private type, leave
11123 class-wide type unfrozen so that freeze nodes can be generated
11124 properly at a later point.
11125 (Freeze_Entity, array case): Handle case of pragma Pack and component
11126 size attributre clause for same array.
11128 2007-08-14 Vincent Celier <celier@adacore.com>

11183 attribute Body in package Naming. Do not replace a source/unit in the
11184 same project when the order of the source dirs are known. Detect
11185 duplicate sources/units in the same project when the order of the
11186 source dirs are not known.
11187 (Check_Ada_Name): Allow all identifiers that are not reserved words

11193 directory of non extending project to nil.
11194 Change type of path name variables to be Path_Name_Type
11195 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

11776 (Collect_Previous_Instances): new procedure within of
11777 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11778 unit being loaded, to ensure that the generation of global symbols is

11781 takes progenitor types into account.
11782 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11783 traversing over the primitives of the formal and actual types to locate
11784 any abstract subprograms of the actual type that correspond to a
11785 nonabstract subprogram of the formal type's ancestor type(s), and issue
11786 an error if such is found.
11787 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

11802 an access_to_constant type.
11803 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11804 type, the candidate operations are found in the scope of declaration of
11805 the type, because the type has no primitive subprograms.
11806 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11807 a private extension, only examine visible components before trying to
11808 analyze as a prefixed call.
11809 Change Entity_List to Type_To_Use, for better readability.

11822 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11823 purpose of enforcing E.2.2(8) only if it is not available at any place.
11824 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11825 when checking the legality of an extension aggregate in a preelaborable
11826 package. Treat the literal null as a valid default expression in a
11827 component declaration for a type with preelaborable initialization.
11828 A limited interface is a legal progenitor for the designated type of a
11829 remote access to class-wide type.

11860 (Resolve): When looping through all possible interpretations of a node,
11861 do not consider those that are hidden by abstract operators.
11862 (Resolve_Actuals): When verifying that an access to class-wide object
11863 is an actual for a controlling formal, ignore anonymous access to
11864 subprograms whose return type is an access to class_wide type.
11865 (Resolve_Slice): If the prefix of the slice is a selected component
11866 whose type depends on discriminants, build its actual subtype before
11867 applying range checks on the bounds of the slice.
11868 (Valid_Conversion): In an instance or inlined body, compare root types,
11869 to prevent anomalies between private and public views.

11891 elabration statements, register the package with the name server
11892 at the beginning, not at the end, of the elaboration statements so

13021 (Selected_Range_Checks): If the node to be checked is a conversion to
13022 an unconstrained array type, and the expression is a slice, use the
13023 bounds of the slice to construct the required constraint checks.
13024 Improve NOT NULL error messages
13025 (Apply_Constraint_Check): If the context is a null-excluding access
13026 type, diagnose properly the literal null.
13028 2007-06-06 Pascal Obry <obry@adacore.com>
13030 * clean.adb (Clean_Archive): Use untouched casing for the archive name
13031 and the corresponding .deps file.
13032 (Clean_Interface_Copy_Directory): Use untouched casing for the library
13033 src directory. Minor code-clean-up. Use untouched casing for files
13034 read into the library src dir.
13035 (Clean_Library_Directory): Idem.
13036 (Parse_Cmd_Line): Accept new switch -aP

13041 Eric Botcazou <ebotcazou@adacore.com>
13042 Arnaud Charlet <charlet@adacore.com>
13044 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13045 applicable to types that have the With_Type flag set. Returns the
13046 non-limited view of the type, if available, otherwise the type itself.
13047 For class-wide types, there is no direct link in the tree, so we have
13048 to retrieve the class-wide type of the non-limited view of the Etype.
13049 New attributes Static_Initialization and Static_Elaboration_Desired.
13050 Remove the pragma Thread_Body, and the associated flag
13051 Is_Thread_Body in entities, and all related code.
13052 (Suppress_Value_Tracking_On_Call): New flag
13053 E_Exception has Esize and Alignment fields
13054 (Universal_Aliasing): New function.
13055 (Set_Universal_Aliasing): New procedure.
13056 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
13057 (Check_Nested_Access): New procedure.
13058 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
13059 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
13060 (Related_Interface): New attribute. Present in dispatch table pointer
13061 components of records. Set to point to the entity of the corresponding
13063 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
13064 (Original_Access_Type): Remove, not needed.
13065 (Root_Type): Handle properly subtypes of class-wide-types.
13068 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13069 class-wide types visible through limited-with clauses.
13070 (Try_Primitive_Operation): When examining all primitive operations of a
13071 tagged type, do not consider subprograms labeled as hidden unless they
13072 belong to a private generic type with a tagged parent.
13073 (Try_Object_Operation): Extensive rewriting, to handle properly various
13074 overloading cases, when several ancestors may have class-wide operations
13075 that are possible candidates, and when the overloaded functions return
13076 array types and have defaulted parameters so that the call may be
13077 interpreted as an indexing.
13078 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13079 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13080 successive actuals before analyzing the call itself.
13081 (Try_Primitive_Operation): A primitive operation is compatible with the
13082 prefix if the prefix has a synchronized type and the type of the formal
13083 is its corresponding record, as can be the case when the primitive
13084 operation is declared outside of the body of the type.
13085 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13086 perform homonym traversal, looking for class-wide operation matches
13087 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13088 access parameters are now restricted to anonymous access types.
13089 (Mark_Allocator): An allocator with a discriminant association parent is
13091 (Try_One_Prefix_Interpretation): If the type of the object is
13092 incomplete, as can be happen when it is a limited view obtained through
13093 a limited_with_clause, the selected component is not part of a prefixed
13095 (Complete_Object_Operation): Diagnose properly an object that is not
13096 aliased when the corresponding controlling formal is an access
13098 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13099 ambiguous calls in prefixed notation, where two primitives differ only
13100 in that the controlling argument of one is an access parameter.
13102 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13103 whether a function that returns an unconstrained type can be inlined.
13104 (Process_Formals): Diagnose properly the illegal use of an incomplete
13105 type in the profile of an access_to_subprogram declaration.
13106 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13107 operations are attached to the corresponding record.
13108 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13109 When processing a primitive of a concurrent type which implements an
13110 interface change the type of all controlling formals to that of the
13111 corresponding record type.
13112 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13113 to determine the tagged type to which a primitive belongs.
13114 (Check_Conventions): Capture condition to ignore a primitive operation
13115 (which is shared between the loop in Check_Conventions and the one in
13116 Check_Convention) in a new local function Skip_Check.
13117 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13118 confusion with Check_Conventions' own Prim_Op local variable.
13119 (Create_Extra_Formals): Test for a tagged result type rather than a
13120 controlling result when determining whether to add a BIP_Alloc_Form
13121 formal and a BIP_Final_List formal to the function.
13122 (Check_Conformance); For parameters that are anonymous access types,
13123 subtype conformance requires that the not null and the constant
13124 indicators must match
13125 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13126 to retrieve the appropriate type when processing a concurrent type
13127 declared within a generic. Minor comment reformatting. Change invocation
13128 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13130 (Analyze_Subprogram_Body): If the return type of a function is an
13131 anonymous access to the limited view of a class-wide type, and the
13132 non-limited view of the type is available, update the type of the
13133 function so that code can be generated.
13134 (Process_Formals): In case of access-subtype itype whose designated
13135 type is also an itype (situation that happens now with access to
13136 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13137 attribute to avoid backend problems.
13138 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13139 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13140 anonymous types' designated types are same before testing
13141 Subtypes_Statically_Match.
13142 (Create_Extra_Formals): Test for a named access parameter that is a
13143 controlling formal as an additional condition for adding an
13144 accessibility level formal. This can occur in the subp type created for
13145 dispatching calls in Expand_Dispatching_Call, and allows calling
13146 Create_Extra_Formals from that procedure rather than special-casing the
13147 extra formals there.
13148 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13149 when the function has a controlling result.
13150 (Check_Returns): Add much more knowledge of the optimization of local
13151 raise statements to gotos, to retain proper warnings in this case.
13152 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13153 nodes when looking for last statement.
13155 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13156 class-wide types visible through limited with clauses.
13157 (Add_One_Interp): If the operands are anonymous access types, the
13158 predefined operator on universal_access is immediately visibles
13159 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13160 other anonymous access types.
13161 (Disambiguate): Take into account CIL convention.
13162 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13164 2007-06-06 Robert Dewar <dewar@adacore.com>
13166 * sinput.ads, sinput.adb, uintp.ads, urealp.adb, stringt.adb,
13167 sem_elim.adb, prj-strt.adb, repinfo.ads, repinfo.adb, namet.ads,
13168 elists.ads, elists.adb, lib.ads, lib.adb (Unlock): New procedure.
13169 Fix lower bound of tables.
13172 * nlists.adb: Ditto.
13173 (Prev_Node, Next_Node): Change index type to Int so that it properly
13174 covers the range First_Node_Id - 1 up.
13176 2007-06-06 Javier Miranda <miranda@adacore.com>
13177 Ed Schonberg <schonberg@adacore.com>
13178 Bob Duff <duff@adacore.com>
13179 Hristian Kirtchev <kirtchev@adacore.com>
13181 * exp_aggr.ads, exp_aggr.adb:
13182 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13183 in extension aggregates.
13184 (Flatten): Other conditions being met, an aggregate is static if the
13185 low bound given by component associations is different from the low
13186 bound of the base index type.
13187 (Packed_Array_Aggregate_Handled): If the component type is itself a
13188 packed array or record, the front-end must expand into assignments.
13189 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13190 Init_Pr, instead of Ancestor_Is_Expression.
13191 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13192 coextension chain root, either generate a list controller or use the
13193 already existing one.
13194 (Static_Array_Aggregate): New procedure to construct a positional
13195 aggregate that can be handled by the backend, when all bounds and
13196 components are compile-time known constants.
13197 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13198 types covering interface types into assignments.
13199 (Replace_Type): move to Build_Record_Aggr_Code.
13200 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13201 interface type, convert to the definite type of the aggregate itself,
13202 so that needed components are visible.
13203 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13204 components and the context is an extended return statement do not
13205 create a transient block for it, to prevent premature finalization
13206 before the return is executed.
13207 (Gen_Assign): Do not generate a call to deep adjust routine if the
13208 component type is itself an array of controlled (sub)-components
13209 initialized with an inner aggregate.
13210 (Component_Check): New name for Static_Check. This name is now more
13211 appropriate, and documentation is added which was missing.
13212 (Component_Check): Add test for bit aligned component value
13213 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13214 Tagged_Comps, name is more appropriate given added function below.
13215 (Component_Not_OK_For_Backend): Check for bit aligned component ref.
13217 2007-06-06 Hristian Kirtchev <kirtchev@adacore.com>
13218 Javier Miranda <miranda@adacore.com>
13219 Robert Dewar <dewar@adacore.com>
13221 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13222 Terminated: Add unchecked type conversion from System.Address to
13223 System.Tasking.Task_Id when calling the predefined primitive
13225 Disable new Ada 05 accessibility check for JVM.NET targets, which
13226 cannot be implemented in a practical way.
13227 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13228 the sources always references the tag of the actual object. Therefore,
13229 if 'Tag is applied in the sources to class-wide interface objects we
13230 generate code that displaces "this" to reference the base of the object.
13231 (Expand_N_Attribute_Reference, case Size): Return specified size if
13232 known to front end.
13233 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13234 has code that displaces the pointer of the object to manage interface
13235 types. However this code must not be executed when the prefix is a
13236 subprogram. This bug caused the wrong expansion of the internally
13237 generated assignment that fills the dispatch table when the primitive
13238 is a function returning a class-wide interface type.
13239 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13240 Set_Attribute_Name for Name_Unaligned_Valid.
13242 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13243 Gary Dismukes <dismukes@adacore.com>
13245 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13246 If the initialization is the equivalent aggregate of the initialization
13247 procedure of the type, do not remove it.
13248 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13249 initialized to null from having their expression reset to empty and
13250 note this exception in the comment.

13254 Ed Schonberg <schonberg@adacore.com>
13255 Gary Dismukes <dismukes@adacore.com>
13257 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
13258 Add "with" and "use" clauses for Sem_Attr.
13259 (Expand_Current_Value): Do not replace occurences of attribute
13260 references where the prefix must be a simple name.
13262 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
13263 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
13264 Attribute_Requires_Simple_Name_Prefix.
13265 (Name_Modifies_Prefix): Body of new function.
13266 (Requires_Simple_Name_Prefix): Body of new function.
13267 (Resolve_Attribute, case Access): Improve error message for case of
13268 mismatched conventions.
13269 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
13271 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13272 constrained subtype for a nominal unconstrained type, use its base type
13273 to check for conformance with the context.
13274 (Resolve_Attribute): Remove test of the access type being associated
13275 with a return statement from condition for performing accessibility
13276 checks on access attributes, since this case is now captured by
13277 Is_Local_Anonymous_Access.
13278 (Analyze_Access_Attribute): Set Address_Taken on entity
13279 (Analyze_Attribute, case Address): Set Address_Taken on entity
13280 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13281 validating an access attribute whose prefix is a current instance.
13282 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13283 applied to dispatching operations, if freezing is required then we set
13284 the attribute Has_Delayed_Freeze in the prefix's entity.
13285 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13286 current scope if access of local subprogram taken
13287 (Analyze_Access_Attribute): Check legality of self-reference even if the
13288 expression comes from source, as when a single component association in
13289 an aggregate has a box association.
13290 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13291 the prefix if it is a protected operation and the attribute is
13292 Unrestricted_Access.
13293 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13294 reference to the base type of the context, to force a constraint check
13295 when the context is an access subtype with an explicit constraint.
13296 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13297 node is rewritten as an interface conversion. leave unanalyzed after
13298 resolution, to ensure that type checking against the context will take

13302 Javier Miranda <miranda@adacore.com>
13303 Robert Dewar <dewar@adacore.com>
13305 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13306 wrapper when the full view of the controlling type of an inherited
13307 function that dispatches on result implements interfaces.
13308 (Expand_N_Object_Declaration): In cases where the type of the
13309 declaration is anonymous access, create finalization list for it.
13310 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13311 if the object has no explicit initialization, to match description of
13312 functionality of pragam Persistent_BSS.
13313 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13314 new function to build static aggregates, to replace initialization call
13315 when static initialization is desired.
13316 (Freeze_Type): Generate a list controller for an access type whenever
13317 its designated type has controlled anonymous access discriminants.
13318 (Build_Equivalent_Aggregate): New procedure to compute a static
13319 aggregate to be used as default initialization for composite types,
13320 instead of a generating a call to the initialization procedure for the
13322 (Build_Initialization_Call): When available, replace a call to the
13323 initialization procedure with a copy of the equivalent static aggregate
13325 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13326 declarations for objects of a class-wide interface type, rather than
13327 just identifiers, to prevent visibility problems.
13328 (Expand_N_Object_Declaration): When expanding the declaration for an
13329 object of a class-wide interface type, preserve the homonym chain of
13330 the original entity before exchanging it with that of the generated
13331 renaming declaration.
13332 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13333 active, because there is no way to handle the exception.
13334 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13335 to do a minimum decoration of the Access_Disp_Table list.
13336 (Expand_Record_Controller): Avoid the addition of the controller between
13337 the component containing the tag of a secondary dispatch table and its
13338 adjacent component that stores the offset to the base of the object.
13339 This latter component is only generated when the parent type has
13340 discriminants ---documented in Add_Interface_Tag_Components).
13341 (Apply_Array_Size_Check): Removed, no longer needed.
13342 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13343 components, create a Master_Entity for it only if it contains tasks.
13344 (Build_Init_Procedure): Suppress the tag assignment compiling under
13346 (Freeze_Record_Type): Remove code associated with creation of dispatch
13348 (Init_Secondary_Tags): Update type of actuals when generating calls to
13349 Ada.Tags.Set_Offset_To_Top
13350 (Stream_Operation_OK): Disable use of streams compiling under no
13352 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13353 if Has_Init_Expression set.
13354 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13355 Register_Primitive, which provides the same functionality.
13356 (Requires_Init_Proc): Return false in case of interface types.
13357 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13359 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13360 is always associated with a predefined primitive because the internal
13361 entities associated with interface types are not predefined primitives.
13362 Therefore, the call to Is_Internal is replaced by a call to the
13363 function Is_Predefined_Dispatching_Operation.
13364 (Make_Eq_If): When generating the list of comparisons for the
13365 components of a given variant, omit the controller component that is
13366 present if the variant has controlled components.
13368 2007-06-06 Javier Miranda <miranda@adacore.com>
13369 Hristian Kirtchev <kirtchev@adacore.com>
13370 Bob Duff <duff@adacore.com>
13372 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13373 handle the creation of finalization lists and calls for nested
13374 coextensions when the root of the chains is part of a return statement.
13375 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13377 (Expand_Record_Equality): Skip components that are interface types.
13378 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13379 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13380 with Rewrite_Coextension. Change the condition for detecting coextension
13382 (Is_Local_Access_Discriminant): Removed.
13383 (Rewrite_Coextension): New routine which rewrites a static coextension
13384 as a temporary and uses its unrestricted access in the construction of
13386 (Complete_Coextension_Finalization): New routine. Generate finalization
13387 attachment calls to all delayed coextensions.
13388 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13389 the allocator is not a coextension itself and has delayed coextensions.
13390 If the current allocator is controlled, but also a coextension, delay
13391 the generation of the finalization attachment call.
13392 Rename local variable "Node" to "Nod" in order to avoid confusion with
13394 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13395 limited types that are not inherently limited. Such an allocator is
13396 illegal, but is generated by the expander for a return statement, to
13397 copy the result onto the secondary stack. This is the only case where a
13398 limited object can be copied. Generate code to displace the pointer
13399 to the object if the qualified expression is a class-wide interface
13400 object. Such displacement was missing and hence the copy of the object
13402 (Apply_Accessibility_Check): Handle allocated objects initialized in
13404 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13405 and Expand_Allocator_Expression. Allocating class-wide interface objects
13406 this routine displaces the pointer to the allocated object to reference
13407 the component referencing the corresponding secondary dispatch table.
13408 Expand_Allocator_Expression): Add missing support to allocate class-wide
13409 interface objects initialized with a qualified expression.
13410 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13411 function result type, and use the finalization list associated with the
13412 function scope in that case (such an anonymous type should not be
13413 treated like an access parameter's type).

13416 Gary Dismukes <dismukes@adacore.com>
13417 Javier Miranda <miranda@adacore.com>
13419 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13420 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13421 required exception handler.
13422 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13423 properly the case of a function whose return type is a limited
13424 class-wide interface type. Modify the code of the accessibility
13425 check to handle class-wide interface objects. In this case we need to
13426 displace "this" to reference the primary dispatch table to get access
13427 to the TSD of the object (to evaluate its accessibility level).
13428 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13429 rather than a controlling result as one of the conditions for
13430 generating tests of the implicit BIP_Alloc_Form formal. The
13431 initialization assignment is also handled according to whether the
13432 result is tagged instead of controlling.
13433 In the case where the init assignment is inserted in the "then" part of
13434 the allocation conditional, rewrite the target to be a dereference of
13435 the implicit BIP_Object_Access formal.
13436 If the returned value is unconstrained and created on the secondary
13437 stack, mark the enclosing block and function so that the secondary
13438 stack is not reclaimed on return.
13439 Treat returns from functions with controlling results similarly to
13440 returns from functions with unconstrained result subtypes.
13441 If the object returned is unconstrained, and an allocator must be
13442 created for it, analyze the allocator once the block for the extended
13443 return is installed, to ensure that finalizable components
13444 of the expression use the proper finalization list. Guard the call to
13445 Move_Final_List with a check that there is something to finalize.
13446 (Make_Tag_Ctrl_Assignment): Use "old" handling
13447 of controlled type assignment for virtual machines, since new code uses
13448 unsupported features (such as direct access to bytes in memory).
13450 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13451 Ed Schonberg <schonberg@adacore.com>
13453 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13454 accessibility actual, check for the case of an aliased object that has
13455 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13456 we fall into processing for the attribute rather than the name of the
13458 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13459 formal has its address taken in the body, create a temporary to capture
13460 value. If the return type is a limited interface, do not treat the
13461 return value as Controlled.
13462 (Is_In_Place_Function): If the return type is a limited interface,
13463 treat as returning in place. The actual returned object may not always
13464 be limited, but the caller has to assume that it is returned in place.
13465 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13466 context of an allocator, use the correct finalization chain (that is,
13467 the chain belonging to the access type, rather than the chain belonging
13468 to the current scope).
13469 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13470 result type rather than a controlling result as a precondition for
13471 adding an allocation form actual to a build-in-place call.
13472 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13473 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13474 primitive in the dispatch tables. This work is now done by Make_DT when
13475 the type is frozen.
13476 (Register_Predefined_DT_Entry): Removed.
13477 (Add_Return): If end label is not present, use sloc of last statement
13478 for generated return statement in procedure, for better gdb behavior
13480 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13481 object address nodes to ensure proper processing by routines like
13483 (Expand_Call): Fix generation of validity check for parameter
13484 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13485 the allocation form parameter if the result subtype is constrained,
13486 except when the function has a controlling result.
13487 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13488 rather than Is_Controlled and Has_Controlled_Component, since we want to
13489 include class-wide result types in this treatment. Also test for a
13490 controlling result, since that also requires passing a finalization
13492 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13493 even when the result subtype is constrained, to handle calls involving
13494 controlling results.
13495 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13496 is now called even when the result subtype is constrained, to handle
13497 calls involving controlling results.
13498 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13499 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13500 now performs the test).
13501 (Make_Build_In_Place_Call_In_Object_Declaration):
13502 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13503 constrained, to handle calls involving controlling results.
13504 (Add_Return): Accomodate rewritten pattern from local raise to goto
13505 transformation, so that we still recognize an transfer statement
13506 and do the right thing here in that case.
13507 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13508 and end of subprogram code.
13509 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13510 support for primitives that are functions (without formals) with a
13511 controlling result.
13512 (Inherited_From_Formal): If the actual subtype has not generic parent
13513 type, it is not an actual for a formal derived type, and there is no
13514 operation to inherit from the formal.
13516 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13517 Thomas Quinot <quinot@adacore.com>
13519 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13520 inserted cleanup code appropriately for GDB use.
13521 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13522 exception handler for Deep_Adjust or Deep_Finalize.
13523 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13524 Raise_From_Controlled_Operation is available, use a call to that
13525 subprogram instead of a plain "raise Program_Error" node to raise
13526 Program_Error if an exception is propagated from an Adjust or Finalize
13528 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13529 appears in the optional statement list of a triggering alternative, the
13530 scope actions can be inserted directly there, and not in the list that
13531 includes the asynchronous select itself.
13533 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13534 Robert Dewar <dewar@adacore.com>
13535 Hristian Kirtchev <kirtchev@adacore.com>
13537 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13538 generated exception handler appropriately when debugging generated code.
13539 Deal properly with No_Exception_Propagation restriction mode.
13540 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13541 System.Address to System.Tasking.Task_Id when processing the result of
13542 the predefined primitive _disp_get_task_id.
13543 (Expand_N_Asynchronous_Select): Clarify comment.
13544 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13545 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13546 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13547 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13548 privals and for generated call to Complete_Entry_Body, for better gdb
13550 (Copy_Result_Type): Utility to construct a parameter and result profile
13551 for protected functions whose return type is an anonymous access to
13553 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13555 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13556 point when the local-raise-to-goto transformation has taken place.
13558 2007-06-06 Javier Miranda <miranda@adacore.com>
13559 Nicolas Setton <setton@adacore.com>
13561 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13562 functionality when the backend is generating code.
13563 Otherwise any serious error
13564 reported by the backend calling the frontend routine Error_Msg
13565 changes the Compilation_Mode to Check_Semantics, disables the
13566 functionality of this routine and causes the generation of
13567 spureous additional errors.
13569 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13570 debugging information now generated by the compiler for fat-pointer
13572 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13574 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13576 2007-06-06 Thomas Quinot <quinot@adacore.com>
13578 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13579 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13580 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13581 For a remote call to a function with a classwide return type, apply an
13582 E.4(18) check to the returned value.
13583 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13584 stream attributes of the designated type of an RACW, as they are not
13585 dispatching primitive operations.
13587 2007-06-06 Geert Bosch <bosch@adacore.com>
13589 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13591 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13593 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13594 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13596 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13598 2007-06-06 Javier Miranda <miranda@adacore.com>
13600 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13601 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13603 2007-06-06 Javier Miranda <miranda@adacore.com>
13605 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13606 deallocation of class-wide interface objects.
13607 (Expand_Dispatching_Constructor_Call): Take into account that if the
13608 result of the dispatching constructor is an interface type, the
13609 function returns a class-wide interface type; otherwise the returned
13610 object would be actual. The frontend previously accepted returning
13611 interface types because Expand_Interface_Actuals silently performed
13612 the management of the returned type "as if" it were a class-wide
13614 (Expand_Dispatching_Constructor_Call): Replace call to
13615 Make_DT_Access_Action by direct call to Make_Function_Call.
13617 2007-06-06 Robert Dewar <dewar@adacore.com>
13618 Ed Schonberg <schonberg@adacore.com>
13620 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13621 compute masking constant, since we now set Esize properly to the
13623 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13624 to match the alignment.
13625 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13626 packed arrays of 8 bits or less.
13628 * freeze.adb (Freeze_Entity): When freezing the formals of a
13629 subprogram, freeze the designated type of a parameter of an access type
13630 only if it is an access parameter.
13631 Increase size of C convention enumeration object
13632 (Freeze_Entity, array type case): Make sure Esize value is properly
13633 adjusted for the alignment if it is known.
13634 (Freeze_Entity, array type case): When checking bit packed arrays for
13635 the size being incorrect, check RM_Size, not Esize.
13636 (Freeze_Record_Type): Check for bad discriminated record convention
13637 (In_Exp_Body): Return true if the body is generated for a subprogram
13638 renaming, either an attribute renaming or a renaming as body.
13639 (Check_Itype): If the designated type of an anonymous access component
13640 is a non-protected subprogram type, indicate that it is frozen, to
13641 prevent out-of-scope freeze node at some subsequent call.
13642 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13643 only if the subprogram is neither imported nor exported, as well as the
13644 NCA descriptor class if the subprogram is exported.
13646 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13647 Arnaud Charlet <charlet@adacore.com>
13648 Robert Dewar <dewar@adacore.com>
13649 Gary Dismukes <dismukes@adacore.com>
13651 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13652 default initialization on an imported object, when there is no
13653 initialization call generated for it.
13654 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13657 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13658 Static_Elaboration_Desired.
13659 Remove pragma Thread_Body.
13660 Implement a new pragma No_Body

13664 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13665 Pragma_CIL_Constructor): New names.
13667 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13668 uses the equivalent aggregate of a type must be treated as an implicit
13670 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13671 has none of the other categories.
13672 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13673 to apply Import to an object renaming declaration.
13675 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13676 from a C++ class should be declared as limited and that it will be
13677 considererd limited.
13678 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13679 should be declared as limited and that it will be considererd limited.
13680 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13681 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13682 (Analyze_Pragma): Deal with Universal_Aliasing.

13698 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13699 set to value that does not match base type size.

13703 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13704 object of a limited type can be initialized with a call to a function
13705 that returns in place. If the limited type has unknown discriminants,
13706 and the underlying type is a constrained composite type, build an actual
13707 subtype from the function call, as is done for private types.
13708 (Side_Effect_Free): An expression that is the renaming of an object or
13709 whose prefix is the renaming of a object, is not side-effect free
13710 because it may be assigned through the renaming and its value must be
13711 captured in a temporary.
13712 (Has_Controlled_Coextensions): New routine.
13713 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13714 as is done for other limited types.

13725 the parent unit is a renaming when the parent is itself a child unit.
13726 Remove handling of with_type clauses.
13728 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13764 Add new warning for renaming of function return objects
13766 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13767 (Tree_Read): Use size of object instead of type'object_size, since the
13768 latter is incorrect for packed array types.

13771 * opt.ads: Add new warning for renaming of function return objects
13772 (Generating_Code): New boolean variable used to indicate that the
13773 frontend as finished its work and has called the backend to process

13784 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
13785 unit is a compilation unit, rather than relying on its scope, so that
13786 Standard can be renamed.
13787 (Analyze_Object_Renaming): Add new warning for renaming of function
13789 Also reject attempt to rename function return object in Ada 83 mode.
13790 (Attribute_Renaming): In case of tagged types, add the body of the
13791 generated function to the freezing actions of the type.
13792 (Find_Type): A protected type is visible right after the reserved word
13793 "is" is encountered in its type declaration. Set the entity and type
13794 rather than emitting an error message.
13795 (New_Scope): Properly propagate Discard_Names to inner scopes

13811 * g-debpoo.ads, g-debpoo.adb (Free_Physically.Free_Blocks): Use the
13812 absolute value of Header.Block_Size when displaying the freed physical
13814 (Allocate): Compute Storage_Address using Integer_Address, not
13815 Storage_Offset, because the range of Storage_Offset may not be large
13817 (Configure): New parameter Low_Level_Traces
13818 (Allocate, Deallocation, Free_Physically): Added low-level traces
13819 (Configure): new parameter Errors_To_Stdout.
13820 (Output_File): new subprogram
13821 (Deallocate, Dereference): Send error messages to the proper stream
13822 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
13823 documented. Previous code would send it to the current output file
13824 defined in GNAT.IO, which might not be stdout
13825 (Is_Valid): Adjust comment to mention that a positive reply means that
13826 Header_Of may be used to retrieve the allocation header associated with
13827 the subprogram Storage address argument. Return False early if this
13828 address argument is misaligned.
13830 2007-06-06 Vincent Celier <celier@adacore.com>

13844 * gnatlink.adb (Gnatlink): Do not specify -static-libgcc when --LINK=
13846 Correct error message when invocation of the linker fails
13847 Add explicit size clause for the C imported variables
13848 Object_List_File_Supported and Using_GNU_Linker to emphasize that
13849 we expect char size.
13850 Read target parameters earlier, since this is needed to set
13851 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
13854 2007-06-06 Vincent Celier <celier@adacore.com>
13857 Add 3 spaces before the default project directory when displaying
13858 the project search path.
13859 Add new command line switch '-l' to display license information.
13861 2007-06-06 Vasiliy Fofanov <fofanov@adacore.com>

13887 (Get_Unit): Accept file names x__... and x~... (where x = a, g, i or s)
13888 on all platforms, as it is not possible to know which one is allowed
13889 before processing the project files.
13890 (Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
13891 specified when symbol policy is Direct. Check that when there is a

13893 Library_Symbol_File) it is not the same as the reference symbol file.
13894 (Check_Stand_Alone_Library): Recognize new symbol policy Direct.

14235 associated with dispatch tables is known at compile time.
14236 (Get_Value): If an association in a record aggregate has a box
14237 association, and the corresponding record component has a default
14238 expression, always copy the default expression, even when the

15338 parameter, rewrite the call as the indexing of a call with a single
15339 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
15341 (Resolve_Actuals): If an actual is an allocator for an access parameter,
15342 the master of the created object is the innermost enclosing statement.
15343 (Remove_Conversions): For a binary operator, check if type of second

15507 * sem_ch6.ads, sem_ch6.adb (Check_Overriding_Indicator): Print
15508 "abstract subprograms must be visible" message, whether or not the type

15536 Remove no longer used entities.
15538 * s-taskin.ads (Activation_Chain): Remove pragma Volatile. It is no

15586 attempt to derive from a synchronized tagged type.

15591 that use (a subtype of) the class-wide type of the enclosing type.
15592 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15593 Derived_Type for Prev formal on call to
15594 Check_Anonymous_Access_Components rather than Empty.
15595 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15596 a record extension in deciding whether to create a class-wide type,

15613 with abstract interfaces.

15650 gnatbind if the ALI file effectively exists.
15651 (Initialize): Add the directory where gnatmake is invoked in front of
15652 the path if it is invoked from a bin directory, even without directory

15677 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15678 when -gnatg is not specified.
15679 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because

15692 (Initialize): Add the directory where gprmake is invoked in front of the
15693 path, if it is invoked from a bin directory or with directory
15694 information, so that the correct GNAT tools will be used when invoked

15704 If the array component is a discriminated record, the array aggregate
15705 is non-static even if the component is given by an aggregate with
15707 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
15708 (Convert_Aggr_In_Allocator): If the allocator is for an access
15709 discriminant and the type is controlled. do not place on a finalization
15710 list at this point. The proper list will be determined from the
15712 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
15713 initialize record controller if needed, before the components, to ensure
15714 that they are properly finalized.
15715 (Build_Record_Aggr_Code): For the case of an array component that has a
15716 corresponding array aggregate in the record aggregate, perform sliding

15729 succeed in that case, even when the expression originates from a
15730 parameter of the containing subprogram.
15731 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15732 under No_Dispatching_Calls restriction. During the semantic analysis
15733 we already notified such violation.
15734 (Tagged_Membership): Constant folding. There is no need to check
15735 the tag at run-time if the type of the right operand is non
15736 class-wide abstract.

15750 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15751 initialize most the TSD components by means of an aggregate.
15752 Modify the declaration of the object containing the TSD
15753 because we now expand code that has a higher level of abstraction.
15754 The TSD has a discriminant containing the Inheritance Depth Level,
15755 value that is used in the membership test but also to fix the size
15756 of the table of ancestors.
15757 (Expand_Interface_Conversion): Insert function body at the closest place
15758 to the conversion expression, to prevent access-before-elaboration
15759 errors in the backend.

15784 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
15785 (Expand_Dispatching_Call): Replace generation of call to the run-time
15786 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
15787 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
15789 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
15790 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
15791 Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
15792 Build_Set_Prim_Op_Address.
15793 (Get_Remotely_Callable): Subprogram removed.
15794 (Init_Predefined_Interface_Primitives): Replace generation of call to
15795 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
15798 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15799 First (Parameter_Associations ()) with the call to First_Actual that
15800 returns an actual parameter expression for both named and positional
15803 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
15804 check violation of restriction No_Dispatching_Calls.
15805 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15806 controlling argument.

15809 First/Next_Component_Or_Discriminant
15810 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
15811 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15812 specify Any_Limited_Interface, and this functionality is already
15813 provided by the function Has_Abstract_Interfaces.
15814 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15815 support concurrent types implementing interfaces.
15816 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15817 specify kind Any_Limited_Interface, and this functionality is already
15818 provided by the function Has_Abstract_Interfaces.
15819 (Remove_Side_Effects): replace Controlled_Type by
15820 CW_Or_Controlled_Type whenever the issue is related to
15821 using or not the secondary stack.
15823 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
15824 P_Interface_Type_Definition to fulfill the new interface (the formal
15825 Is_Synchronized is no longer required).
15827 * Make-lang.in (GNAT_ADA_OBJS): Addition of exp_atag.o
15828 Update dependencies.

15836 * exp_ch7.ads, exp_ch7.adb (Find_Final_List): If the access type is
15837 anonymous, use finalization list of enclosing dynamic scope.
15838 (Expand_N_Package_Declaration): For a library package declaration
15839 without a corresponding body, generate RACW subprogram bodies in the
15840 spec (just as we do for the task activation call).
15841 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15842 Is_Abstract_Type. Make sure these are called only when appropriate.
15843 Remove all code for DSP option
15844 (CW_Or_Controlled_Type): new subprogram.

15850 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
15851 parameter. If it is set to true, return a result capped according to
15852 the global upper bound for the index of an entry family.
15853 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
15854 (Build_Find_Body_Index): Adjust for above change.
15855 (Entry_Index_Expression): Likewise.

15860 Family_Size with 'Cap' set to true.
15861 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
15862 a protected version of an operation declared in the private part of
15863 a protected object, because they may be invoked through a callback.
15864 (Set_Privals): If the type of a private component is an anonymous access
15865 type, do not create a new itype for each protected body.
15866 If the body of a protected operation creates
15867 controlled types (including allocators for class-widetypes), the
15868 body of the corresponding protected subprogram must include a
15870 (Build_Activation_Chain_Entity): Build the chain entity for extended
15872 (Type_Conformant_Parameters): Use common predicate Conforming_Types
15873 to determine whether operation overrides an inherited primitive.

15875 for a possible overriding candidate.
15876 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
15877 hold an actual parameter value since its initialization is separated
15878 from the the declaration. Prevents errors on null-excluding access

15882 Pablo Oliveira <oliveira@adacore.com>
15884 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
15885 Do an Unchecked_Conversion to handle the passage from the Underlying

15887 Build_From_Any_Call.
15888 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
15889 E_Constant, depending upon Variable formal.
15890 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
15891 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
15892 parameter that requires an extra constrained parameter, declare
15893 temporary for actual as a variable, not a constant.
15894 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
15895 the unit being compiled is the one that contains the stub type.
15896 Change primitive operation name for the RACW associated with a RAS
15897 from Call to _Call so it cannot clash with any legal identifier.
15898 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
15900 (Append_RACW_Bodies): New subprogram.
15901 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
15902 Add_Receiving_Stubs_To_Declarations functions.
15903 When expanding a package body, this list correspond to the
15904 statements in the HSS at the end of the pacakge.
15905 When expanding a package spec, this list correspond to the

15908 registering the receiving stubs at the end of the 'Stmts' list.
15909 (RCI_Package_Locator): Pass the new Version generic formal when
15910 instantiating a RCI_Locator package.
15911 (Build_From_Any_Function): To compute the High bound for an
15912 unconstrained array actual, we add the Low bound with the length.
15913 Thus we must convert the low bound and the length to an appropriate
15914 type before doing the sum.
15915 (Build_Subprogram_Receiving_Stubs, PolyORB):
15916 * Retrieve the extra formals parameters at the
15917 end of the parameter stream.
15918 * Use Move_Any_Value to write back out parameters
15919 after executing the request as it is more efficient
15920 than Copy_Any_Value.
15921 * Build the any containing Extra Formals with the
15922 appropriate typecode.
15923 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
15924 empty Component_List.
15925 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
15926 the tree the declaration for an object that serves as actual parameter
15927 in server-side stubs.

15937 function with the first not implicit parent type.
15938 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
15939 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
15940 typecode from the Etype. Therefore we retrieve the correct typecode
15941 with a call to Get_Any_Type.
15942 (Copy_Specification): Do controlling formal type substitution based on
15943 Is_Controlling_Formal flag, instead of caller-provided object type.
15944 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
15945 a RACW primitive operation, we might get a subprogram declaration for an
15946 ancestor of the RACW designated type (not for the designated type
15947 itself), in the case where this operation is inherited. In this case we
15948 have no easy means of determining the original tagged type for which
15949 the primitive was declared, so instead we now rely on
15950 Copy_Specification to use the Is_Controlling_Formal flag to determine
15951 which formals require type substitution.

15957 GNAT.Current_Exception are not allowed if pragma Restrictions
15958 (No_Exception_Propagation) is set and in any case make the associated
15959 handler unsuitable as a target for a local raise statement.
15960 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
15961 run-time subprogram CW_Membership by call to Build_CW_Membership.
15962 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
15963 by a function call, a temporary must be created before expanding the
15964 Constructor_Call itself, to prevent out-of-order elaboration in the
15965 back-end when stack checking is enabled..
15967 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15969 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
15970 result are the bounds of the left operand, not the right.
15972 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15975 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15987 box corresponds to a component of the type.
15988 (Resolve_Record_Aggregate): Split Is_Abstract flag into

16092 * mingw32.h (S2WSU): New macro to convert from a string to a
16093 wide-string using the UTF-8 encoding. The S2WS macro supports now only
16094 standard 8bits encoding.
16095 (WS2SU): As above but converting from wide-sring to string.
16096 This is needed as it is necessary to have access to both versions in the
16097 runtime for the form parameter encoding support.
16098 This set of patch add support for the encoding form parameter.
16099 (S2WS): Improve implementation to handle cases where the filename is not
16100 UTF-8 encoded. In this case we default to using the current code page
16101 for the conversion.
16103 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16104 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16113 corresponding encoding value into AFCB structure.
16114 (Reset): Pass the encoding value to freopen.

16148 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16149 __gnat_adjust_context_for_raise.
16150 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16151 implementation of floating point operations as native x86 targets.
16152 So the FPU should be initialized in the same way using finit. Fix
16153 floating point operations accuracy issues.
16154 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16155 member in struct sigaction, so as to avoid warning for incompatible

16173 * lib-xref.ads, lib-xref.adb:
16174 Modify the loop that collects type references, to include interface
16175 types that the type implements. List each of these interfaces when
16176 building the entry for the type.
16177 (Generate_Definition): Initialize component Def and Typ of new entry
16178 in table Xrefs, to avoid to have these components unitialized.
16179 (Output_References): Split Is_Abstract flag into
16180 Is_Abstract_Subprogram and Is_Abstract_Type.
16181 (Generate_Reference): Add barrier to do not generate the warning
16182 associated with Ada 2005 entities with entities generated by the

16222 2007-04-06 Robert Dewar <dewar@adacore.com>
16224 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16225 it no longer destroys the contents of Name_Buffer or Name_Len and
16226 non-standard and invalid names are handled better.
16227 (Get_Decoded_Name_String): Improve performance by using
16228 Name_Has_No_Encodings flag in the name table.
16229 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16230 Used for debugging printouts.

16233 Javier Miranda <miranda@adacore.com>
16234 Bob Duff <duff@adacore.com>
16236 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16237 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16238 there is no need to generate always a record_definition_node in case
16239 of synchronized interface types.
16240 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16241 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16242 illegal in Ada 95, in cases where it is legal. Change the warnings to
16243 errors in other cases. Don't give the error unless the "not null"
16244 parses properly. Correct the source position at which the error occurs.
16245 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16246 P_Null_Exclusion, to suppress "not null" warnings.

16298 Entry for pragma Unreferenced_Objects
16300 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16301 switches, without repetition of "eD". Make sure that last character of
16302 -gnatep= switch is not taken as -gnat switch character.
16303 Complete rewrite of circuit for handling saving compilation options

16322 the default project path, initially done during elaboration of the
16324 If the prefix returned by Sdefault is null, get the prefix from a call
16325 to Executable_Prefix_Path.
16326 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16329 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16330 canonical directory name to open the directory from which files are
16332 (Record_Other_Sources): Idem.
16333 (Locate_Directory): Add the possibility to create automatically missing
16334 directories when Setup_Projects is True.
16335 Call Locate_Directory so that the directory will be created when
16336 Setup_Projects is True, for object dir, library dir, library ALI dir,
16337 library source copy dir and exec dir.
16339 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16342 2007-04-06 Robert Dewar <dewar@adacore.com>

16376 * s-carun8.adb, s-carsi8.adb (Compare_Array_?8): modify so that last
16377 full word is no longer compared twice.
16379 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16381 * sem_ch10.adb (Install_Limited_Context_Clauses.
16382 Expand_Limited_With_Clause): Use a new copy of selector name in the
16383 call to Make_With_Clause. This fixes the tree structure for ASIS
16384 purposes. Nothing is changed in the compiler behaviour.
16385 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16386 a package renaming.
16387 (Install_Limited_With_Clauses): Do not install non-limited view when it
16388 is still incomplete.
16390 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16391 Gary Dismukes <dismukes@adacore.com>
16393 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16394 when capturing size information, instead of base type, which for a
16395 formal array type will be the unconstrained type.
16396 (Analyze_Formal_Object_Declaration): Add check for illegal default
16397 expressions for a formal in object of a limited type.
16398 (Instantiate_Object): Ditto.
16399 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16400 because they were defaulted in the formal package and no check applies
16402 (Check_Formal_Package_Instance): Extend conformance check to other
16403 discrete types beyond Integer.
16404 (Process_Default): Copy directly the unmatched formal. A generic copy
16405 has already been performed in Analyze_Formal_Package.
16406 (Analyze_Associations): If a formal subprogram has no match, check for
16407 partial parametrization before looking for a default, to prevent
16409 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16410 not set the instantiation environment before analyzing the actuals.
16411 Fixes regression on 8515-003 with implementation of AI-133.
16412 Set_Instance_Env checks whether the generic unit is a predefined
16413 unit, in which case the instance must be analyzed with the latest Ada
16414 mode. This setting must take place after analysis of the actuals,
16415 because the actuals must be analyzed and frozen in the Ada mode extant
16416 outside of the current instantiation.
16417 (Save_Env, Restore_Env): Preserve and restore the configuration
16418 parameters so that predefined units can be compiled in the proper Ada
16420 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16421 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16422 and Is_Abstract_Type.
16423 (Analyze_Formal_Package): For better error recovery, Add exception
16424 handler to catch Instantion_Error, which can be raised in
16425 Analyze_Associations
16427 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16428 Bob Duff <duff@adacore.com>
16429 Gary Dismukes <dismukes@adacore.com>
16431 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16432 prefix type is a discriminated subtype of the type of the formal.
16433 (Analyze_Allocator): Collect all coextensions regardless of the context.
16434 Whether they can be allocated statically is determined in exp_ch4.
16435 (Analyze_Selected_Component): If the prefix is a limited view and the
16436 non-limited view is available, use the non-limited one.
16437 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16438 therefore illegal), suggest a qualified expression rather than a type
16439 conversion, because a type conversion would be illegal in this context.
16440 (Anayze_Allocator): Trace recursively all nested allocators so that all
16441 coextensions are on the corresponding list for the root. Do no mark
16442 coextensions if the root allocator is within a declaration for a stack-
16443 allocated object, because the access discriminants will be allocated on
16445 (Analyze_Call): Remove restriction on calls to limited functions for the
16446 cases of generic actuals for formal objects, defaults for formal objects
16447 and defaults for record components.
16448 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16449 element list. Their expansion is delayed until the enclosing allocator
16450 is processed and its finalization list constructed.
16451 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16452 for an operation with the given name among the primitive operations of
16453 the corresponding record type.
16454 (Analyze_Selected_Component): If the prefix is a task type that
16455 implements an interface, and there is no entry with the given name,
16456 check whether there is another primitive operation (e.g. a function)
16458 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16459 properly the indexing of a function call written in prefix form, where
16460 the function returns an array type, and all parameters of the function
16461 except the first have defaults.
16462 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16463 the original operands, rather than relocating them, for efficiency and
16464 to work properly when an operand is overloaded.
16465 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16466 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16467 (Analyze_Selected_Component): If the prefix is a private extension, only
16468 scan the visible components, not those of the full view.
16469 (Try_Primitive_Operation): If the operation is a procedure, collect all
16470 possible interpretations, as for a function, because in the presence of
16471 classwide parameters several primitive operations of the type can match
16472 the given arguments.
16474 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16475 Robert Dewar <dewar@adacore.com>
16477 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
16478 tag-indeterminate call to an abstract function, when the left-hand side
16480 (Analyze_Loop_Statement): Improve detection of infinite loops
16482 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16483 Thomas Quinot <quinot@adacore.com>
16485 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
16486 out of Analyze_Package_Declaration, because processing must be applied
16487 to package bodies as well, for deferred constants completed by pragmas.
16488 (Analyze_Package_Declaration): When the package declaration being
16489 analyzed does not require an explicit body, call Check_Completion.
16490 (May_Need_Implicit_Body): An implicit body is required when a package
16491 spec contains the declaration of a remote access-to-classwide type.
16492 (Analyze_Package_Body): If the package contains RACWs, append the
16493 pending subprogram bodies generated by exp_dist at the end of the body.
16494 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
16495 Is_Abstract_Subprogram and Is_Abstract_Type.
16496 (Preserve_Full_Attributes): The full entity list is not an attribute
16497 that must be preserved from full to partial view.
16499 * sem_dist.adb (Add_RAS_Dereference_TSS):
16500 Change primitive name to _Call so it cannot clash with any legal
16501 identifier, and be special-cased in Check_Completion.
16502 Mark the full view of the designated type for the RACW associated with
16503 a RAS as Comes_From_Source to get proper view switching when installing
16504 private declarations.
16505 Provite a placeholder nested package body along with the nested spec
16506 to have a place for Append_RACW_Bodies to generate the calling stubs
16507 and stream attributes.
16509 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16510 Robert Dewar <dewar@adacore.com>
16512 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
16513 that is a limited view, check the non-limited view if available.
16514 (Undefined): Refine error message for missing with of Text_IO
16515 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
16516 to distinguish real missing with cases.
16517 Fix format of all missing with messages
16518 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
16519 renaming as body when renamed entity is abstract.
16521 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16522 Javier Miranda <miranda@adacore.com>
16524 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
16525 predicate recursive, to handle complex expressions on literals whose
16526 spurious ambiguity comes from the abstract interpretation of some
16528 (Interface_Present_In_Ancestor): Add support to concurrent record
16530 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
16531 Is_Abstract_Subprogram and Is_Abstract_Type.
16533 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16534 Javier Miranda <miranda@adacore.com>
16536 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16537 dereference of a local object R created as a reference to another
16538 object O, use the access level of O.
16539 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16540 rather than local Same_Formal_Type, to check whether protected operation
16541 overrides an inherited one.
16542 (Same_Formal_Type): New predicate, used when matching signatures of
16543 overriding synchronized operations, to handle the case when a formal
16544 has a type that is a generic actual.
16545 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16546 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
16547 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
16548 syntactic ambiguities involving indexing of function calls that return
16550 (Abstract_Interface_List): New subprogram that returns the list of
16551 abstract interfaces associated with a concurrent type or a
16552 concurrent record type.
16553 (Interface_Present_In_Parent): New subprogram used to check if a
16554 given type or some of its parents implement a given interface.
16555 (Collect_Abstract_Interfaces): Add support for concurrent types
16556 with interface types.
16557 (Has_Abstract_Interfaces): Add support for concurrent types with
16559 (Is_Parent): New subprogram that determines whether E1 is a parent
16560 of E2. For a concurrent type its parent is the first element of its
16561 list of interface types; for other types this function provides the
16562 same result than Is_Ancestor.
16563 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16564 (Collect_Synchronized_Interfaces): Removed because the subprogram
16565 Collect_Abstract_Interfaces provides this functionality.
16566 (Collect_Abstract_Interfaces): Minor update to give support to
16567 concurrent types and thus avoid undesired code duplication.
16568 (Get_Subprogram_Entity): Handle entry calls.
16569 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
16571 (Enter_Name): Do not give -gnatwh hiding warning for record component
16572 entities, they never result in hiding.

16575 Robert Dewar <dewar@adacore.com>
16577 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
16578 to chain nested components that are allocators for access discriminants
16579 of the enclosing object.
16580 Add N_Push and N_Pop nodes
16581 New field Exception_Label added
16582 (Local_Raise_Statements): New field in N_Exception_Handler_Node
16583 (Local_Raise_Not_OK): New flag in N_Exception_Handler_Node
16584 (Is_Coextension): New flag for allocators, to mark allocators that
16585 correspond to access discriminants of dynamically allocated objects.
16586 (N_Block_Statement): Document the fact that the corresponding entity
16587 can be an E_Return_Statement.
16588 (Is_Coextension): New flag for allocators.

16902 anonymous access types.
16903 (Valid_Conversion): For a conversion to a numeric type occurring in an

16961 zone data and calculate the GMT offset.
16962 (__gnat_localtime_tzoff for Darwin, Free BSD, Linux, Lynx and Tru64):

17490 rewritten replacement for Apply_Alignment_Check
17491 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
17492 we request a discriminal value only in case of discriminants.
17493 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17494 assignments where the target subtype is unconstrained and the target
17495 object is a parameter or dereference (other aliased cases are known
17496 to be unconstrained).

17610 the parent part is a build-in-place function call, generate assignments.
17611 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
17612 are build-in-place function calls.
17613 (Replace_Self_Reference): New subsidiary of
17614 Make_OK_Assignment_Statement, to replace an access attribute that is a
17615 self-reference into an access to the appropriate component of the
17616 target object. Generalizes previous mechanism to handle self-references
17617 nested at any level.
17618 (Is_Self_Referential_Init): Remove, not needed.
17619 (Is_Self_Referential_Init): New predicate to simplify handling of self
17620 referential components in record aggregates.

17622 check for presence of entity before checking for self-reference.
17623 (Has_Default_Init_Comps): Return True if a component association is a
17624 self-reference to the enclosing type, which can only come from a
17625 default initialization.
17626 (Make_OK_Assignment_Statement): If the expression is of the form
17627 Typ'Acc, where Acc is an access attribute, the expression comes from a
17628 default initialized self-referential component.
17629 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17630 that has been derived from several abstract interfaces we must also
17631 initialize the tags of the secondary dispatch tables.

17636 Robert Dewar <dewar@adacore.com>
17639 (Expand_Access_To_Protected_Op): If the context indicates that an access
17640 to a local operation may be transfered outside of the object, create an
17641 access to the wrapper operation that must be used in an external call.
17642 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17643 target, pass the Valid attribute applied to a floating-point prefix on
17644 to the back end without expansion.
17645 (Storage_Size): Use the new run-time function Storage_Size to retrieve
17646 the allocated storage when it is specified by a per-object expression.
17647 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
17648 Nothing to do here, the attribute has been rewritten during semantic

17657 into a fat pointer.
17658 (Is_Constrained_Aliased_View): New predicate to help determine whether a
17659 subcomponent's enclosing variable is aliased with a constrained subtype.
17660 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17661 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17662 an aliased prefix must be known to be constrained in order to use True
17663 for the attribute value, and now it's possible for some aliased views
17664 to be unconstrained.
17666 2006-10-31 Robert Dewar <dewar@adacore.com>
17668 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
17669 (Expand_Entity_Reference): Correct error of not handling subprogram
17670 formals in current_value processing.
17672 2006-10-31 Javier Miranda <miranda@adacore.com>

17675 Gary Dismukes <dismukes@adacore.com>
17677 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
17678 register in the final list objects containing class-wide interfaces;
17679 otherwise we incorrectly register the tag of the interface in the final
17681 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17682 generate the wrapper if the parent primitive is abstract. This is
17683 required to report the correct error message.
17684 (Expand_N_Subtype_Indication): Do validity checks on range
17685 (Clean_Task_Names): If an initialization procedure includes a call to
17686 initialize a task (sub)component, indicate that the procedure will use
17687 the secondary stack.
17688 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
17689 compatibility for interfacing with CPP by default.
17690 (Expand_N_Object_Declaration): Only build an Adjust call when the
17691 object's type is a nonlimited controlled type.
17692 * exp_ch3.adb: Add with and use of Exp_Ch6.
17693 (Expand_N_Object_Declaration): Check for object initialization that is a
17694 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17695 Object_Declaration to the call.
17696 (Freeze_Type): When the designated type of an RACW was not frozen at the
17697 point where the RACW was declared, validate the primitive operations
17698 with respect to E.2.2(14) when it finally is frozen.
17699 (Build_Initialization_Call,Expand_Record_Controller): Rename
17700 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17701 return-by-reference has no meaning in Ada 2005.
17702 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
17703 to register tag of the immediate ancestor interfaces in the
17704 run-time structure.
17705 (Init_Secondary_Tags): Moved to the specification to allow the
17706 initialization of extension aggregates with abstract interfaces.
17707 (Build_Master_Renaming): Make public, for use by function declarations
17708 whose return type is an anonymous access type.
17709 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17710 Insert_List_Before_And_Analyze after the generation of the specs
17711 associated with null procedures.
17712 (Expand_Tagged_Root): Update documentation in its specification.
17713 (Init_Secondary_Tags): Update documentation.
17714 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17715 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17716 then generate code to inherit the contents of the dispatch table
17717 directly from the ancestor.
17718 (Expand_Record_Controller): Insert controller component after tags of
17719 implemented interfaces.
17720 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
17721 create null procedure overridings when null procedures are inherited
17723 (Make_Null_Procedure_Specs): New procedure to generate null procedure
17724 declarations for overriding null primitives inherited from interfaces.
17725 (Is_Null_Interface_Procedure): New function in
17726 Make_Null_Procedure_Specs.
17727 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17728 immediate ancestor of a tagged type is an abstract interface type we
17729 must generate the specification of the predefined primitives associated
17730 with controlled types (because the dispatch table of the ancestor is
17731 null and hence these entries cannot be inherited). This is required to
17732 elaborate well the dispatch table.

17742 (Expand_N_In): Do validity checks on range
17743 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
17744 (Expand_N_Allocator): For "new T", if the object is constrained by
17745 discriminant defaults, allocate the right amount of memory, rather than
17746 the maximum for type T.
17747 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17748 when the allocator is initialized by a build-in-place call, since the
17749 allocator is already rewritten as a reference to the function result,
17750 and this prevents an unwanted duplication of the function call.
17751 Add with and use of Exp_Ch6.
17752 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17753 is a call to build-in-place function and apply
17754 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17755 untagged designated types).
17756 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
17757 optimization if source or target is biased.
17758 (Expand_N_Allocator): Add comments for case of an allocator within a
17759 function that returns an anonymous access type designating tasks.
17760 (Expand_N_Allocator): apply discriminant checks for access
17761 discriminants of anonymous access types (AI-402, AI-416)

17770 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
17771 (Expand_N_Assignment_Statement): Call
17772 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
17773 build-in-place function call. Currently, this can happen only for
17774 assignments that come from aggregates.
17775 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17776 in order to alleviate the upward compatibility introduced by AI-318.
17777 (Expand_N_Extended_Return_Statement): Add support for handling the
17778 return object as a build-in-place result.
17779 (Expand_Non_Function_Return): Implement simple return statements nested
17780 within an extended return.
17781 (Enable_New_Return_Processing): Turn on the new processing of return
17783 (Expand_Non_Function_Return): For a return within an extended return,
17784 don't raise Program_Error, because Sem_Ch6 now gives a warning.
17785 (Expand_N_Extended_Return_Statement): Implement AI-318
17786 (Expand_Simple_Function_Return): Ditto.
17787 (Expand_N_If_Statement): Handle new -gnatwt warning

17789 (Expand_N_Assignment): Handle assignment to the Priority attribute of
17790 a protected object.
17791 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
17792 validity checking of assignments to elementary record components.
17793 (Expand_N_Return_Statement): return Class Wide types on the secondary
17794 stack independantly of their controlled status since with HIE runtimes,
17795 class wide types are not potentially controlled anymore.
17797 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17800 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17801 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17802 it expects a block, procedure, or task. The return statement will get
17803 turned into a block, and Expand_Cleanup_Actions will happen then.

17807 Bob Duff <duff@adacore.com>
17808 Gary Dismukes <dismukes@adacore.com>
17810 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17812 (Expand_Inlined_Call): Tagged types are by-reference types, and
17813 therefore should be replaced by a renaming declaration in the expanded
17814 body, as is done for limited types.
17815 (Expand_Call): If this is a call to a function with dispatching access
17816 result, propagate tag from context.
17817 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17819 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17820 build-in-place when the right-hand side of an assignment is a
17821 build-in-place function call.
17822 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17823 of the explicit dereference of the allocator to the result subtype of
17824 the build-in-place function. This is needed to satisfy type checking
17825 in cases where the caller's return object is created by an allocator for
17826 a class-wide access type and the type named in the allocator is a
17828 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17829 conversion of the reference to the declared object to the result subtype
17830 of the build-in-place function. This is needed to satisfy type checking
17831 in cases where the declared object has a class-wide type. Also, in the
17832 class-wide case, change the type of the object entity to the specific
17833 result subtype of the function, to avoid passing a class-wide object
17834 without explicit initialization to the back end.
17835 (Register_Interface_DT_Entry): Moved outside the body of
17836 Freeze_Subprogram because this routine is now public; it is called from
17837 Check_Dispatching_Overriding to handle late overriding of abstract
17838 interface primitives.
17839 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17840 adding an implicit access actual on a call to a build-in-place function.
17841 (Expand_Actuals): Test for an actual parameter that is a call to a
17842 build-in-place function and apply
17843 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17844 (Is_Build_In_Place_Function): New function to determine whether an
17845 entity is a function whose calls should be handled as build-in-place.
17846 (Is_Build_In_Place_Function_Call): New function to determine whether an
17847 expression is a function call that should handled as build-in-place.
17848 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17849 calls to build-in-place functions as the initialization of an allocator.
17850 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17851 handling calls to build-in-place functions in contexts that do not
17852 involve init of a separate object (for example, actuals of subprogram
17854 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17855 handling calls to build-in-place functions as the initialization of an
17856 object declaration.

17858 instantiation of Traverse_Body to avoid unreferenced warning.
17859 (Check_Overriding_Inherited_Interfaces): Removed.
17860 (Register_Interface_DT_Entry): Code cleanup.
17861 (Register_Predefined_DT_Entry): Code cleanup.
17862 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
17863 inlined statements if within a transient scope.
17864 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
17865 formal parameters with occurrences of actuals in inlined body, establish
17866 visibility on the proper view of the actual's subtype for the body's
17868 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
17869 compatibility mode and we have an imported CPP subprogram because
17870 for now we assume that imported CPP primitives correspond with
17871 objects whose constructor is in the CPP side (and therefore we
17872 don't need to generate code to register them in the dispatch table).
17873 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
17874 aligned selected component.
17875 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
17876 the actual of an in-mode parameter is a type conversion.
17877 (Expand_Actuals): If the call does not come from source and the actual
17878 is potentially misaligned, let gigi handle it rather than rejecting the
17879 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
17880 Class Wide types as returning by reference independantly of their
17881 controlled status since with HIE runtimes class wide types are not
17882 potentially controlled anymore.
17884 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17886 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
17887 references that are private components of the protected object.

17889 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
17890 instantiation to deal with warnings.

17897 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
17898 initialization of Homonym_Len.
17899 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
17900 names from fully qualified name. Fixes problem of duplicate
17901 external names differing only in the presence of such a block name.
17903 2006-10-31 Thomas Quinot <quinot@adacore.com>
17904 Pablo Oliveira <oliveira@adacore.com>
17906 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
17907 subprogram Ids, even if they are not yet assigned.
17908 (Build_Subprogram_Id): It is now this function that will take care of
17909 calling Assign_Subprogram_Ids if necessary.
17910 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
17911 should be done only once they are assigned.
17912 (Build_From_Any_Function, case of tagged types): Add missing call to
17914 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
17915 type for an RACW type.
17916 (Add_RACW_Features): When processing an RACW declaration for which the
17917 designated type is already frozen, enforce E.2.2(14) rules immediately.
17918 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
17919 special reordering of controlling formals.
17921 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
17922 associated stub type for an RACW type.
17924 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17926 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
17927 fixed-point operations in an integer context, i.e. as operands of a
17928 conversion to an integer type, indicate that result must be rounded.
17930 2006-10-31 Robert Dewar <dewar@adacore.com>
17932 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
17933 cases, pass the encoding method, since it is now required by the run
17936 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
17937 assumption that Str'First = 1.
17938 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
17939 it on to the Value_Wide_Wide_Character call.
17940 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
17941 properly handles a string of the form quote-encoded_wide_char-quote.
17943 * s-wchcnv.adb: Minor reformatting
17945 2006-10-31 Javier Miranda <miranda@adacore.com>
17947 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
17948 run-time membership test to ensure that the constructed object
17949 implements the target abstract interface.
17951 2006-10-31 Robert Dewar <dewar@adacore.com>
17953 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
17954 Machine_Attribute pragma internally to implement the user pragma.
17955 Add processing for pragma Interface so that it is now completely
17956 equivalent to pragma Import.
17958 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
17959 so that it can be applied to all entities, including record components
17960 and enumeration literals.
17961 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
17962 priority ranges are correct, verify compatibility against task
17963 dispatching and locking policies, and if everything is correct an entry
17964 is added to the table containing priority specific dispatching entries
17965 for this compilation unit.
17966 (Delay_Config_Pragma_Analyze): Delay processing
17967 Priority_Specific_Dispatching pragmas because when processing the
17968 pragma we need to access run-time data, such as the range of
17969 System.Any_Priority.
17970 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
17971 Allow pragma Unreferenced as a context item
17972 Add pragma Preelaborable_Initialization
17973 (Analyze_Pragma, case Interface): Interface is extended so that it is
17974 now syntactically and semantically equivalent to Import.
17975 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
17976 insertion characters.
17977 Add handling for Pragma_Wide_Character_Encoding
17978 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17979 never supercedes a real restriction, and that a real restriction
17980 always supercedes a warning.
17981 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of
17984 2006-10-31 Bob Duff <duff@adacore.com>
17985 Ed Schonberg <schonberg@adacore.com>
17986 Robert Dewar <dewar@adacore.com>
17988 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17989 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17990 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17992 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17993 type of the function containing a return statement, because the
17994 Return_Type field was removed. We now use the Return_Applies_To field.
17996 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17997 (Build_Task_Image_Decl): If procedure is not called from an
17998 initialization procedure, indicate that function that builds task name
17999 uses the sec. stack. Otherwise the enclosing initialization procedure
18000 will carry the indication.
18001 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18002 N_Object_Declaration instead.
18003 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18004 conditional dead code killed, and change implementation accordingly.
18005 (Insert_Actions): Add N_Return_Object_Declaration case.
18006 Correct comment to mention N_Extension_Aggregate node.
18007 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18008 attempts to save information for global variables which cannot be
18010 (Get_Current_Value_Condition): Handle conditions the other way round
18011 (constant on left). Also handle right operand of AND and AND THEN
18012 (Set_Current_Value_Condition): Corresponding changes
18013 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18014 (Get_Current_Value_Condition): Handle simple boolean operands
18015 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18016 (Get_Current_Value_Condition): If the variable reference is within an
18017 if-statement, does not appear in the list of then_statments, and does
18018 not come from source, treat it as being at unknown location.
18019 (Get_Current_Value_Condition): Enhance to allow while statements to be
18020 processed as well as if statements.
18021 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18023 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18024 of loop. This is safe now that we fixed Kill_Current_Values.
18025 (OK_To_Do_Constant_Replacement): Check whether current scope is
18026 Standard, before examining outer scopes.
18028 2006-10-31 Vincent Celier <celier@adacore.com>
18030 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18031 When True, apply VMS treatment to children of packages A, G, I and S.
18034 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18036 2006-10-31 Robert Dewar <dewar@adacore.com>
18037 Ed Schonberg <schonberg@adacore.com>
18039 * freeze.adb: Add handling of Last_Assignment field
18040 (Warn_Overlay): Supply missing continuation marks in error msgs
18041 (Freeze_Entity): Add check for Preelaborable_Initialization
18043 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18045 * g-expect.adb: Add Warnings (Off) to prevent new warning
18047 * lib-xref.adb: Add handling of Last_Assignment field
18048 (Generate_Reference): Centralize handling of pragma Obsolescent here
18049 (Generate_Reference): Accept an implicit reference generated for a
18050 default in an instance.
18051 (Generate_Reference): Accept a reference for a node that is not in the
18052 main unit, if it is the generic body corresponding to an subprogram
18055 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18057 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18059 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18061 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18062 use clauses, to avoid messages on packages used to qualify, and also
18063 to avoid messages from obsolescent units.
18064 (Warn_On_Useless_Assignments): Don't generate messages for imported
18065 and exported variables.
18066 (Warn_On_Useless_Assignments): New procedure
18067 (Output_Obsolescent_Entity_Warnings): New procedure
18068 (Check_Code_Statement): New procedure
18070 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

18072 (Last_Assignment): New field for useless assignment warning
18074 2006-10-31 Olivier Hainque <hainque@adacore.com>
18076 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18077 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18079 2006-10-31 Bob Duff <duff@adacore.com>
18080 Robert Dewar <dewar@adacore.com>
18081 Ed Schonberg <schonberg@adacore.com>
18083 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18084 Ada 95 mode, because it violates the new rules for AI-318.
18086 * g-awk.ads: Use overloaded subprograms in every case where we used to
18087 have a default of Current_Session. This makes the code closer to be
18088 correct for both Ada 95 and 2005.
18090 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18091 code, relying on the fact that the compiler generates a warning
18092 instead of an error in -gnatg mode.
18094 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18095 E_Return_Statement entity kind.
18096 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18098 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18099 report an error if the reserved word abstract has been previously found.
18100 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18102 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18103 parenthesized range attribute usage
18104 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18106 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18107 in the syntax for extended_return_statement. This is not in the latest
18108 RM, but the ARG is expected to issue an AI allowing this.
18109 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18110 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18111 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18112 P_Return_Statement): Parse the new syntax for extended_return_statement.
18114 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18115 Output_End_Missing): Add error-recovery code for the new
18116 extended_return_statement syntax; that is, the new E_Return entry on
18119 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18120 limited to nonlimited, because otherwise we violate the new Ada 2005
18121 rules about returning limited types in function Create_AST_Handler in
18124 * sem.adb (Analyze): Add cases for new node kinds
18125 N_Extended_Return_Statement and N_Return_Object_Declaration.
18127 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18128 type is in the same category as type of context before applying check,
18129 to prevent anomalies in instantiations.
18130 (Resolve_Aggregate): Remove test for limited components in aggregates.
18131 It's unnecessary in Ada 95, because if it has limited components, then
18132 it must be limited. It's wrong in Ada 2005, because limited aggregates
18134 (Resolve_Record_Aggregate): Move check for limited types later, because
18135 OK_For_Limited_Init requires its argument to have been resolved.
18136 (Get_Value): When copying the component default expression for a
18137 defaulted association in an aggregate, use the sloc of the aggregate
18138 and not that of the original expression, to prevent spurious
18139 elaboration errors, when the expression includes function calls.
18140 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18141 were missing. We also didn't handle qualified expressions. Now also
18142 allow function calls. Use new common routine OK_For_Limited_Init.
18143 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18144 with space can upper case letter).
18146 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18147 Has_Static_Discriminants flag
18148 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18149 type with discriminants.
18150 (Process_Range_Expr_In_Decl): Do validity checks on range
18151 (Build_Discriminant_Constraints): Use updated form of
18152 Denotes_Discriminant.
18153 (Process_Subtype): If the subtype is a private subtype whose full view
18154 is a concurrent subtype, introduce an itype reference to prevent scope
18156 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18157 Record_Type_Declaration): The functionality of the subprograms
18158 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18159 is now performed by a single routine.
18160 (Build_Derived_Record_Type): If the type definition includes an explicit
18161 indication of limitedness, then the type must be marked as limited here
18162 to ensure that any access discriminants will not be treated as having
18163 a local anonymous access type.
18164 (Check_Abstract_Overriding): Issue a detailed error message when an
18165 abstract subprogram was not overridden due to incorrect mode of its
18167 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18168 synchronized private extension declarations. Verify that the ancestor is
18169 a limited or synchronized interface or in the generic case, the ancestor
18170 is a tagged limited type or synchronized interface and all progenitors
18171 are either limited or synchronized interfaces.
18172 Derived_Type_Declaration): Check for presence of private extension when
18173 dealing with synchronized formal derived types.
18174 Process_Full_View): Enchance the check done on the usage of "limited" by
18175 testing whether the private view is synchronized.
18176 Verify that a synchronized private view is completed by a protected or
18178 (OK_For_Limited_Init_In_05): New function.
18179 (Analyze_Object_Declaration): Move check for limited types later,
18180 because OK_For_Limited_Init requires its argument to have been resolved.
18181 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18182 in order to alleviate the upward compatibility introduced by AI-318.
18183 (Constrain_Corresponding_Record): If the constraint is for a component
18184 subtype, mark the itype as frozen, to avoid out-of-scope references to
18185 discriminants in the back-end.
18186 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18187 this subprogram against wrong sources.
18188 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18189 discriminant of limited type completed with a protected type, when the
18190 discriminant is used to constrain a private component of the type, and
18191 expansion is disabled.
18192 (Find_Type_Of_Object): Do not treat a return subtype that is an
18193 anonymous subtype as a local_anonymous_type, because its accessibility
18194 level is the return type of the enclosing function.
18195 (Check_Initialization): In -gnatg mode, turn the error "cannot
18196 initialize entities of limited type" into a warning.
18197 (OK_For_Limited_Init): Return true for generated nodes, since it
18198 sometimes violates the legality rules.
18199 (Make_Incomplete_Declaration): If the type for which an incomplete
18200 declaration is created happens to be the currently visible entity,
18201 preserve the homonym chain when removing it from visibility.
18202 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18203 inherited subprograms.
18204 (Access_Definition): If this is an access to function that is the return
18205 type of an access_to_function definition, context is a type declaration
18206 and the scope of the anonymous type is the current one.
18207 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18208 incomplete subtype to the set of private dependents of the original
18210 (Constrain_Discriminated_Type): Emit an error message whenever an
18211 incomplete subtype is being constrained.
18212 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18213 corresponding subtype of the full view of the original incomplete type.
18214 (Check_Incomplete): Properly detect invalid usage of incomplete types
18217 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18219 * g-catiio.ads, g-catiio.adb (Value): New function.

18228 Robert Dewar <dewar@adacore.com>
18230 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18231 handling executable extension manually and duplicating code.
18233 * make.adb: Implement new -S switch
18234 (Gnatmake): Use new function Osint.Executable_Name instead
18235 of handling executable extension manually.
18237 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18238 is specified, the executable name ends with this suffix.
18239 Take advantage of Osint.Executable_Name instead of duplicating code.
18241 * switch-m.adb: Recognize new gnatmake -S switch
18243 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18245 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18248 * makeusg.adb: Add line for gnatmake -S switch
18250 2006-10-31 Vincent Celier <celier@adacore.com>
18252 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18253 call it with -static-libgcc, as there are some platforms, such as
18254 Darwin, where one of these two switches is compulsory to link.
18256 2006-10-31 Vincent Celier <celier@adacore.com>
18258 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18259 instead of ADA_PROJECT_PATH, for the project path.
18260 (Gnatls): When displaying the project path directories, use host dir
18263 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18264 names in the project path, as absolute paths may correspond to
18265 multi-valued VMS logical names.
18267 2006-10-31 Vincent Celier <celier@adacore.com>
18269 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18270 absolute path name.
18271 (Locate_Regular_File): Ditto
18272 (Change_Dir): Remove, no longer used
18273 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18274 on Windows. Get it calling Get_Current_Dir.
18275 (OpenVMS): Remove imported boolean, no longer needed.
18276 (Normalize_Pathname)[VMS]: Do not resolve directory names.
18277 (Pid_To_Integer): New function to convert a Process_Id to Integer
18279 2006-10-31 Thomas Quinot <quinot@adacore.com>
18281 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
18282 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
18284 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
18287 2006-10-31 Robert Dewar <dewar@adacore.com>
18289 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18290 initial letter o as a zero.
18292 2006-10-31 Robert Dewar <dewar@adacore.com>
18294 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18296 2006-10-31 Robert Dewar <dewar@adacore.com>
18298 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18300 (Layout_Variant_Record): Retrieve the discriminants from the entity
18301 rather than from the type definition, because in the case of a full
18302 type for a private type we need to take the discriminants from the
18304 (Layout_Component_List): When applying the Max operator to variants with
18305 a nonstatic size, check whether either operand is static and scale that
18306 operand from bits to storage units before applying Max.
18307 (Layout_Type): In VMS, if a C-convention access type has no explicit
18308 size clause (and does not inherit one in the case of a derived type),
18309 then the size is reset to 32 from 64.
18311 2006-10-31 Vincent Celier <celier@adacore.com>
18313 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18314 its file has already been loaded, according to the unit being loaded,
18315 not to the current value of Multiple_Unit_Index.
18317 2006-10-31 Thomas Quinot <quinot@adacore.com>
18318 Eric Botcazou <ebotcazou@adacore.com>
18319 Arnaud Charlet <charlet@adacore.com>
18321 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18322 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18324 (a-except.o): Pass it to the compiler.
18325 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18326 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18327 a-calend-mingw.adb version.
18329 * Makefile.rtl: Added s-dsaser.
18330 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
18331 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
18332 Ada.Dispatching.Round_Robin.
18333 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18335 * Make-lang.in: Remove all references to gt-ada-decl.h.
18336 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

18343 2006-10-31 Vincent Celier <celier@adacore.com>
18345 * mlib-utl.adb (Initialized): Remove, no longer used
18346 (Initialize): Remove, no longer used
18347 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18348 if there is one, the archive indexer. Fail if the archive builder cannot
18350 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18353 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18355 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18356 Process_Body_Clauses): If the context of a body includes a use clause
18357 for P.Q then a with_clause for P in the same body is not redundant,
18358 even if the spec also has a with_clause on P.
18359 Add missing continuation mark to error msg
18360 (Build_Limited_Views): A limited view of a type is tagged if its
18361 declaration includes a record extension.
18362 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18363 node, even if the subunit has errors. This avoids malfunction by
18364 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18365 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18366 generation of obsolescent messages for with statements (cannot do
18367 this too early, or we cannot implement avoiding the messages in the
18368 case of obsolescent units withing obsolescent units).
18369 (Install_Siblings): If the with_clause is on a remote descendant of

18373 the analysis of the private part of a nested package, to remove from
18374 visibility the private with_clauses of the enclosing package
18376 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18377 now centralized in Generate_Reference.
18378 (Install_Limited_Context_Clauses): Remove superfluous error
18379 message associated with unlimited view visible through use
18380 and renamings. In addition, at the point in which the error
18381 is reported, we add the backslash to the text of the error
18382 to ensure that it is reported as a single error message.
18383 Use new // insertion for some continuation messages
18384 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18385 to create implicit with_clause for parent unit mentioned in original
18386 limited_with_clause.
18387 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18388 unit is a child unit. For ASIS queries.
18389 (Analyze_Subunit): If the subunit appears within a child unit, make all
18390 ancestor child units directly visible again.

18406 with a null exclusion.
18407 (P_Generic_Association): Handle association with box, and others_choice
18408 with box, to support Ada 2005 partially parametrized formal packages.

18453 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18454 dot, instead of replacing only the first '_'.
18456 * prj-part.adb (Parse): Convert project file path to canonical form
18458 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18459 extended, the project id of the project extending it is recorded in its

18468 Robert Dewar <dewar@adacore.com>
18470 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18471 only a restriction warning is active for the given restriction. This is
18472 desirable because we do not want to modify code in the case where only
18474 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18475 causes overriding of real restrictions.
18476 Take advantage of new No_Restrictions constant.
18478 * raise.h: (__gnat_set_globals): Change profile.
18480 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18482 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18485 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.

18505 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18506 properly an attempt to apply Unchecked_Access to a protected operation.
18507 (OK_Self_Reference): New subprogram to check the legality of an access
18508 attribute whose prefix is the type of an enclosing aggregate.
18509 Generalizes previous mechanism to handle attribute references nested
18510 arbitrarily deep within the aggregate.
18511 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18512 can appear in an aggregate if this is a default-initialized aggregate
18513 for a self-referential type.
18514 (Resolve_Attribute, case Access): Ditto.
18515 Add support for new implementation defined attribute Stub_Type.

18520 Has_Specified_Stream_Attribute flag.
18521 Disallow Storage_Size and Storage_Pool for access to subprogram
18522 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18523 access types of return subtypes in extended return statements. Remove
18524 accessibility checks on anonymous access types when Unchecked_Access is
18526 (Analyze_Attribute): Add support for the use of 'Class to convert
18527 a class-wide interface to a tagged type.
18528 Add support for the attribute Priority.
18529 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18530 whether the designated type is discriminated with a constrained partial
18531 view and require static matching in that case.
18532 Add local variable Des_Btyp. The Designated_Type
18533 of an access to incomplete subtype is either its non-limited view if
18534 coming from a limited with or its etype if regular incomplete subtype.
18536 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18537 Fix predicate to identify and allow cases of (expander-generated)
18538 references to tag of designated object of a RACW.
18539 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18540 non-static, and therefore cannot appear as a primary in a preelaborable
18542 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18543 Has_Read_Write_Attributes.
18544 (Has_Read_Write_Attributes): Reimplement in termes of
18545 Has_Stream_Attribute_Definition.
18546 (Missing_Read_Write_Attributes): When checking component types in a
18547 record, unconditionally call Missing_Read_Write_Attributes recursively
18548 (remove guard checking for Is_Record_Type / Is_Access_Type).
18550 2006-10-31 Robert Dewar <dewar@adacore.com>
18552 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18553 useless assignments here and conditionalize it on absence of exception

18556 detection code, for new handling of formal packages.
18558 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18559 Hristian Kirtchev <kirtchev@adacore.com>
18561 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18562 that has been constant-folded, preserve information of original tree,
18564 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18565 generated private extension declaration if the formal derived type is
18566 synchronized. Carry synchronized present over to the generated private
18568 (Validate_Derived_Type_Instance): Ensure that the actual of a
18569 synchronized formal derived type is a synchronized tagged type.
18570 (Instantiate_Formal_Package): When creating the instantiation used to
18571 validate the actual package of a formal declared without a box, check
18572 whether the formal itself depends on a prior actual.
18573 (Instantiate_Formal_Subprogram): Create new entities for the defining
18574 identifiers of the formals in the renaming declaration, for ASIS use.
18575 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18576 a renaming declaration or a subtype declaration for an actual in an
18577 instance, capture location information of declaration in generic, for
18579 (Instantiate_Formal_Package): Add comments on needed additional tests.
18580 AI-317 (partial parametrization) is fully implemented.
18581 (Validate_Private_Type_Instance): Add check for actual which
18582 must have preelaborable initialization
18583 Use new // insertion for some continuation messages
18584 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18585 Default_Expression. Add type retrieval when the declaration has an
18586 access definition. Update premature usage of incomplete type check.
18587 (Check_Access_Definition): New subsidiary routine. Check whether the
18588 current compilation version is Ada 05 and the supplied node has an
18590 (Instantiate object): Alphabetize local variables. Handle the creation
18591 of new renaming declarations with respect to the kind of definition
18592 used - either an access definition or a subtype mark. Guard against
18593 unnecessary error message in the context of anonymous access types after
18594 they have been resolved. Add check for required null exclusion in a
18595 formal object declaration.
18596 (Switch_View): A private subtype of a non-private type needs to be
18597 switched (the base type can have been switched without its private
18598 dependents because of the last branch of Check_Private_View.
18599 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18601 (Instantiate_Type): Emit an error message whenever a class-wide type of
18602 a tagged incomplete type is used as a generic actual.
18603 (Find_Actual_Type): Extend routine to handle a component type in a child
18604 unit that is imported from a formal package in a parent.
18605 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18606 agree on constrainedness, rather than checking against ultimate ancestor
18607 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18608 generic body, for navigation purposes.
18610 2006-10-31 Robert Dewar <dewar@adacore.com>
18611 Thomas Quinot <quinot@adacore.com>
18613 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18615 (New_Stream_Subprogram): When processing an attribute definition clause
18616 for a stream-oriented subprogram, record an entity node occurring at
18617 the point of clause to use for checking the visibility of the clause,
18618 as defined by 8.3(23) as amended by AI-195.
18619 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18620 New_Stream_Function and New_Stream_Procedure.
18621 (New_Stream_Function, New_Stream_Procedure): Removed.
18622 (Analyze_Attribute_Definition_Clause, case Address): Check new
18623 Alignment_Check check

18626 Javier Miranda <miranda@adacore.com>
18627 Robert Dewar <dewar@adacore.com>
18629 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18630 generate the same errors compiling under -gnatc.
18631 (Try_Object_Operation): If no candidate interpretation succeeds, but
18632 there is at least one primitive operation with the right name, report
18633 error in call rather than on a malformed selected component.
18634 (Analyze_Selected_Component): If the prefix is an incomplete type from
18635 a limited view, and the full view is available, use the full view to
18636 determine whether this is a prefixed call to a primitive operation.
18637 (Operator_Check): Verify that a candidate interpretation is a binary
18638 operation before checking the type of its second formal.
18639 (Analyze_Call): Add additional warnings for function call contexts not
18641 (Analyze_Allocator): Move the check for "initialization not allowed for
18642 limited types" after analyzing the expression. This is necessary,
18643 because OK_For_Limited_Init looks at the structure of the expression.
18644 Before analysis, we don't necessarily know what sort of expression it
18645 is. For example, we don't know whether F(X) is a function call or an
18646 indexed component; the former is legal in Ada 2005; the latter is not.
18647 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18648 were missing. We also didn't handle qualified expressions. Now also
18649 allow function calls. Use new common routine OK_For_Limited_Init.
18650 (Analyze_Type_Conversion): Do not perform some legality checks in an
18651 instance, because the error message will be redundant or spurious.
18652 (Analyze_Overloaded_Selected_Component): Do not do style check when
18653 setting an entity, since we do not know it is the right entity yet.
18654 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18655 (Analyze_Overloaded_Selected_Component): Same change
18656 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18657 since regular incomplete subtypes are transformed into corresponding
18658 subtypes of their full views.
18659 (Complete_Object_Operation): Treat name of transformed subprogram call
18660 as coming from source, for browsing purposes.
18661 (Try_Primitive_Operation): If formal is an access parameter, compare
18662 with base type of object to determine whether it is a primitive
18664 (Operator_Check): If no interpretation of the operator matches, check
18665 whether a use clause on any candidate might make the operation legal.
18666 (Try_Class_Wide_Operation): Check whether the first parameter is an
18667 access type whose designated type is class-wide.
18669 2006-10-31 Robert Dewar <dewar@adacore.com>
18670 Ed Schonberg <schonberg@adacore.com>

18674 warn on infinite loops.
18675 Add \\ to some continuation messages
18676 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18677 (Process_Bounds): If the bounds are integer literals that result from
18678 constant-folding, and they carry a user-defined type, preserve that type
18679 rather than treating this as an integer range.
18680 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18681 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18682 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18683 left hand side of assignment.
18684 (Analyze_Assignment): Add suport to manage assigments to the attribute
18685 priority of a protected object.
18686 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18687 not just identifiers.
18688 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18689 or AND THEN for possible tracking.
18690 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18691 case of while loops so we can track values in the loop body.
18693 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18694 Hristian Kirtchev <kirtchev@adacore.com>
18695 Bob Duff <duff@adacore.com>
18697 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18698 procedure cannot be a protected operation (it is a basic_declaration,
18699 not a subprogram_declaration).
18700 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18701 Subp. Add logic for entry processing.
18702 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18703 Determine whether an entry or subprogram of a protected or task type
18704 override an inherited primitive of an implemented interface.
18705 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
18706 Update the actual used in calls to Check_Overriding_Indicator.
18707 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
18708 generate the proper reference to the parent unit, for cross-reference.
18709 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
18711 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18712 (Add_Extra_Formal): Revise procedure to allow passing in associated
18713 entity, scope, and name suffix, and handle setting of the new
18714 Extra_Formals field.
18715 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18716 pass new parameters. Add support for adding the new extra access formal
18717 for functions whose calls are treated as build-in-place.
18718 (Analyze_A_Return_Statement): Correct casing in error message.
18719 Move Pop_Scope to after Analyze_Function_Return, because an extended
18720 return statement really is a full-fledged scope. Otherwise, visibility
18721 doesn't work right. Correct use of "\" for continuation messages.
18722 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18723 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18724 the node doesn't get properly marked as analyzed.
18725 (Analyze_Subprogram_Body): If subprogram is a function that returns
18726 an anonymous access type that denotes a task, build a Master Entity
18728 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18729 proper usage of null exclusion in a result definition.
18730 (Process_Formals): Code cleanup and new error message.
18731 (Process_Formals): Detect incorrect application of null exclusion to
18733 (Conforming_Types): Handle conformance between [sub]types and itypes
18734 generated for entities that have null exclusions applied to them.
18735 (Maybe_Primitive_Operation): Add an additional type retrieval when the
18736 base type is an access subtype. This case arrises with null exclusions.
18737 (New_Overloaded_Entity): Do not remove the overriden entity from the
18738 homonym chain if it corresponds with an abstract interface primitive.
18739 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18740 call to the synthesized predicate Is_Incomplete_Type.
18741 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18743 (Analyze_Subprogram_Declaration): Check that abstract interface
18744 primitives are abstract or null.
18745 (Analyze_Subprogram_Specification): Remove previous check for abstract
18746 interfaces because it was not complete.
18747 (Has_Interface_Formals): Removed.
18749 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18750 Javier Miranda <miranda@adacore.com>
18752 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
18753 of Analyze_Package_Body, to create Itype references for anonymous
18754 access types created in the package declaration, whose designated types
18755 may have only a limited view.
18756 (Analyze_Package_Specification): For the private part of a nested
18757 package, install private_with_clauses of enclosing compilation unit if
18758 we are in its visible part.
18759 (Declare_Inherited_Private_Subprograms): Complete barrier
18760 to ensure that the primitive operation has an alias to some parent
18761 primitive. This is now required because, after the changes done for the
18762 implementation of abstract interfaces, the contents of the list of
18763 primitives has entities whose alias attribute references entities of
18764 such list of primitives.
18765 (Analyze_Package_Specification): Simplify code that handles parent units
18766 of instances and formal packages.
18767 (Uninstall_Declarations): Check the convention consistency among
18768 primitive overriding operations of a tagged record type.

18777 expected and found set right)
18778 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
18779 (Analyze_Generic_Renaming): Same fix
18780 (Use_One_Package): Do not take into account the internal entities of
18781 abstract interfaces during the analysis of entities that are marked
18782 as potentially use-visible.
18783 (Find_Type): Handle the case of an attribute reference for
18784 implementation defined attribute Stub_Type (simply let the analysis of
18785 the attribute reference rewrite it).
18786 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
18787 type that appears in a Use_Type clause.
18788 (Analyze_Object_Renaming): Add support for renaming of the Priority
18790 (Find_Type): In Ada 2005, a task type can be used within its own body,
18791 when it appears in an access definition.
18792 (Analyze_Object_Renaming): Remove warning on null_exclusion.
18793 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18794 in a formal object declaration or in a subtype declaration.
18795 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18796 (Check_Null_Exclusion): New local routine to
18797 Analyze_Subprogram_Renaming. Check whether the formals and return
18798 profile of a renamed subprogram have required null exclusions when
18799 their counterparts of the renaming already impose them.
18800 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18801 Determine whether an entity is inside a generic scope.
18802 (In_Open_Scope): First pass of documentation update.
18803 (Find_Expanded_Name): Add support for shadow entities associated with
18804 limited withed packages. This is required to handle nested packages.
18805 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18806 that makes a renaming of a limited withed package illegal.

18811 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18812 Check_Overriding_Indicator.
18813 (Analyze_Task_Definition): Ditto.
18814 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18815 (Check_Overriding_Indicator): To find overridden interface operation,

20261 after hyphen (small aesthetic change useful for a range of numbers
20263 Suppress range checks for a couple of assignments which otherwise
20264 cause validity checks with validity checking turned on.
20266 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case Size):
20267 Improvement in error message for object.
20268 (Rep_Item_Too_Late): Remove '!' in warning message.

20271 Eric Botcazou <ebotcazou@adacore.com>
20273 * err_vars.ads: Suppress range checks for a couple of assignments
20274 which otherwise cause validity checks with validity checking turned on.

20284 implied by '?' in error messages.
20286 * gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
20287 (Gnat1drv): Use a goto to end of main subprogram instead of
20288 Exit_Program (E_Success) so that finalization can occur normally.
20290 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>

20306 Thomas Quinot <quinot@adacore.com>
20308 * checks.adb (Build_Discriminant_Checks): If the expression being
20309 checks is an aggregate retrieve the values of its discriminants to
20310 generate the check, rather than creating a temporary and a reference
20312 (Apply_Access_Check): Rewritten to handle new Is_Known_Null flag
20313 (Install_Null_Excluding_Check): Ditto
20314 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

20327 error message with the full switch.
20328 Eliminate numeric switches for binder/gnatmake
20330 * switch.ads, switch.adb (Bad_Switch): New procedure
20332 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
20333 Remove 0-9 as debug flag character possibilities
20334 -d is now controlling the primary stack size when its value is a
20335 positive. Also add checks against invalid values, and support for kb,
20336 mb. Ditto for -D switch.
20338 2006-02-13 Robert Dewar <dewar@adacore.com>
20339 Serguei Rybin <rybin@adacore.com>
20341 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20342 save/restore routines.
20343 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20344 were not always properly handled previously.
20345 Since we are changing the tree format anyway, also get rid of the
20346 junk obsolete Immediate_Errors flag.
20347 (Tree_Read): Change the way of reading Tree_Version_String - now we
20348 read the version string from the tree even if its length is not the
20349 same as the length of the version string computed from Gnatvsn.
20350 (Search_Directory_Present): New Boolean flag for the compiler.
20351 Define Tree_Version_String as a dynamic string.
20352 (Default_Stack_Size): new variable, used to handle switch -d.

20356 only for main unit.
20357 Add pragma Ada_2005 (synonym for Ada_05)
20358 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20359 were not always properly handled previously.

20365 Robert Dewar <dewar@adacore.com>
20366 Ed Schonberg <schonberg@adacore.com>
20368 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
20369 against errors in the source program: a private types for which the
20370 corresponding full type declaration is missing and pragma CPP_Virtual
20372 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
20373 (Is_Known_Null): New flag
20374 (Has_Pragma_Pure): New flag
20375 (No_Return): Present in all entities, set only for procedures
20376 (Is_Limited_Type): A type whose ancestor is an interface is limited if
20377 explicitly declared limited.
20378 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
20379 entities. Only used for component marked Is_Tag. If present it stores
20380 the Offset_To_Top function used to provide this value in tagged types
20381 whose ancestor has discriminants.
20383 * exp_ch2.adb: Update status of new Is_Known_Null flag
20385 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
20387 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
20388 the categorization sense if Is_Pure was set by pragma Pure_Function.
20390 2006-02-13 Quentin Ochem <ochem@adacore.com>
20391 Olivier Hainque <hainque@adacore.com>
20393 * bindusg.adb: Updated documentation for -d and -D switches.
20395 * raise.h (__gnat_set_globals): added new parameter for
20396 Default_Stack_Size.
20398 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
20399 (__gnat_handle_vms_condition): Adjust context before raise.
20400 (__gnat_install_handler): Restore the global vector setup for GCC
20401 versions before 3.4, as the frame based circtuitry is not available
20403 (__gnat_set_globals): added a parameter default_stack_size
20404 (__gl_default_stack_size): new variable.
20406 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20408 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
20409 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
20410 does not exist in the Ada RM.
20411 (Compatible_Int_Bounds): Determine whether two integer range bounds
20412 are of equal length and have the same start and end values.
20413 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20414 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20415 aggregate when it is part of an object declaration.
20416 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20417 constrains discriminants of its parent, add explicitly the discriminant
20418 constraints of the ancestor by retrieving them from the
20419 stored_constraint of the parent.
20421 2006-02-13 Robert Dewar <dewar@adacore.com>
20423 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20424 attribute Mechanism_Code is applied to renamed subprogram, modify
20425 prefix to point to base subprogram.
20426 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20428 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20429 renamed subprograms so that the front-end must replace the prefix
20432 2006-02-13 Javier Miranda <miranda@adacore.com>
20433 Gary Dismukes <dismukes@adacore.com>
20435 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20436 availability of RE_Interface_Tag.
20437 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20438 (Freeze_Record_Type): Do not generate the tables associated with
20439 timed and conditional dispatching calls through synchronized
20440 interfaces if compiling under No_Dispatching_Calls restriction.
20441 When compiling for Ada 2005, for a nonabstract
20442 type with a null extension, call Make_Controlling_Function_Wrappers
20443 and insert the wrapper function declarations and bodies (the latter
20444 being appended as freeze actions).
20445 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20446 predefined primitives associated with timed and conditional
20447 dispatching calls through synchronized interfaces if we are
20448 compiling under No_Dispatching_Calls.
20449 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20450 service is available before generating a call.
20451 (Make_Controlling_Function_Wrappers): New procedure.
20452 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20453 access-to-limited-interfaces because they can be used to reference
20454 tasks that implement such limited interface.
20455 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20456 procedure spec and body of the Offset_To_Top function that is generated
20457 when the parent of a type with discriminants has secondary dispatch
20459 (Init_Secondary_Tags): Handle the case in which the parent of the type
20460 containing secondary dispatch tables has discriminants to generate the
20461 correct arguments to call Set_Offset_To_Top.
20462 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20464 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20465 Add Wide_[Wide_]Expanded_Name.
20466 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20467 the same functionality of Get_Prim_Op_Address but applied to predefined
20468 primitive operations because the pointers to the predefined primitives
20469 are now saved in a separate table.
20470 (Parent_Size): Modified to get access to the separate table of primitive
20471 operations or the parent type.
20472 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20473 functionality of Set_Prim_Op_Address but applied to predefined primitive
20475 (Set_Signature): New subprogram used to store the signature of a DT.
20476 (Displace): If the Offset_To_Top value is not static then call the
20477 function generated by the expander to get such value; otherwise use
20478 the value stored in the table of interfaces.
20479 (Offset_To_Top): The type of the actual has been changed to Address to
20480 give the correct support to tagged types with discriminants. In this
20481 case this value is stored just immediately after the tag field.
20482 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20483 offset_to_top value is static and hence pass this value to the run-time
20484 to store it in the table of interfaces, or else if this value is dynamic
20485 and then pass to the run-time the address of a function that is
20486 generated by the expander to provide this value for each object of the
20489 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20490 (Default_Prim_Op_Count): New entity
20491 (Get_Predefined_Prim_Op_Address): New entity
20492 (Set_Predefined_Prim_Op_Address): New entity
20493 (RE_Set_Signature): New entity
20495 2006-02-13 Thomas Quinot <quinot@adacore.com>
20496 Ed Schonberg <schonberg@adacore.com>
20498 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
20499 Make_Adjust_Call done for a newly-allocated object.
20501 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20502 in a subprogram are wrapped in a cleanup block, indicate that the
20503 subprogram contains an inner block with an exception handler.
20504 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20505 Adjust call is for a newly-allocated object. In that case we must not
20506 assume that the finalization list chain pointers are correct (since they
20507 come from a bit-for-bit copy of the original object's pointers) so if
20508 the attach level would otherwise be zero (no change), we set it to 4
20509 instead to cause the pointers to be reset to null.
20511 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20512 reset chain pointers to null.
20514 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20516 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20517 string, and the context requires a loop for the assignment (e.g.
20518 because the left-hand side is packed), generate a unique name for the
20519 temporary that holds the string, to prevent spurious name clashes.
20521 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20522 Javier Miranda <miranda@adacore.com>
20523 Robert Dewar <dewar@adacore.com>
20524 Gary Dismukes <dismukes@adacore.com>
20526 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20527 return unconstrained arrays.
20529 (Expand_Call): An indirect call through an access parameter of a
20530 protected operation is not a protected call.
20531 Add circuit to raise CE in Ada 2005 mode following call
20532 to Raise_Exception.
20533 (Register_DT_Entry): Do nothing if
20534 the run-time does not give support to abstract interfaces.
20535 (Freeze_Subprogram): In case of dispatching operations, do not generate
20536 code to register the operation in the dispatch table if the source
20537 is compiled with No_Dispatching_Calls.
20538 (Register_Predefined_DT_Entry): Generate code that calls the new
20539 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20540 Set_Prim_Op_Address.
20542 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20543 on array assignments if the right-hand side is a function call that has
20544 been inlined. Check is performed on the assignment in the block.
20545 (Process_Bounds): If bounds and range are overloaded, apply preference
20546 rule for root operations to disambiguate, and diagnose true ambiguity.
20547 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20548 a tag-indeterminate right-hand side even when Expander_Active is True.
20549 Needed to ensure that dispatching calls to T'Input are allowed and
20550 get the tag of the target class-wide object.
20552 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20553 an inherited primitive operation that already overrides several
20554 abstract interface primitives. For transitivity, the new entity must
20555 also override all the abstract interface primitives covered by the
20556 inherited overriden primitive.
20557 Emit warning if new entity differs from homograph in same scope only in
20558 that one has an access parameter and the other one has a parameter of
20559 a general access type with the same designated type, at the same
20560 position in the signature.
20561 (Make_Inequality_Operator): Use source locations of parameters and
20562 subtype marks from corresponding equality operator when creating the
20563 tree structure for the implicit declaration of "/=". This does not
20564 change anything in behaviour except that the decoration of the
20565 components of the subtree created for "/=" allows ASIS to get the
20566 string images of the corresponding identifiers.
20567 (Analyze_Return_Statement): Remove '!' in warning message.
20568 (Check_Statement_Sequence): Likewise.
20569 (Analyze_Subprogram_Body): For an access parameter whose designated type
20570 is an incomplete type imported through a limited_with clause, use the
20571 type of the corresponding formal in the body.
20572 (Check_Returns): Implicit return in No_Return procedure now raises
20573 Program_Error with a compile time warning, instead of beging illegal.
20574 (Has_Single_Return): Function returning unconstrained type cannot be
20575 inlined if expression in unique return statement is not an identifier.
20576 (Build_Body_To_Inline): It is possible to inline a function call that
20577 returns an unconstrained type if all return statements in the function
20578 return the same local variable. Subsidiary procedure Has_Single_Return
20579 verifies that the body conforms to this restriction.
20581 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20582 same type, and one of them is of an anonymous access type, convert
20583 the other operand to it, so that this is a valid binary operation for
20585 (Resolve_Type_Conversion): Handle subtypes of protected types and
20586 task types when accessing to the corresponding record type.
20587 (Resolve_Allocator): Add '\' in 2-line warning message.
20588 Remove '!' in warning message.
20589 (Resolve_Call): Add '\' in 2-line warning message.
20590 (Valid_Conversion): Likewise.
20591 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20592 resulting type may be an access type with an implicit dereference.
20593 Obtain the proper component from the designated type.
20594 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20595 given by an expanded name with prefix Standard, when the operands are
20596 of an anonymous access type.
20597 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20598 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20599 prefix of the expression is not of an incomplete type. Allows full
20600 diagnoses of all semantic errors.
20601 (Resolve_Actuals): If the actual is an allocator whose directly
20602 designated type is a class-wide interface we build an anonymous
20603 access type to use it as the type of the allocator. Later, when
20604 the subprogram call is expanded, if the interface has a secondary
20605 dispatch table the expander will add a type conversion to force
20606 the displacement of the pointer.
20607 (Resolve_Call): If a function that returns an unconstrained type is
20608 marked Inlined_Always and inlined, the call will be inlined and does
20609 not require the creation of a transient scope.
20610 (Check_Direct_Boolean_Op): Removed
20611 (Resolve_Comparison_Op): Remove call to above
20612 (Resolve_Equality_Op): Remove call to above
20613 (Resolve_Logical_Op): Inline above, since this is only call.
20614 (Valid_Conversion): Handle properly conversions between arrays of
20615 convertible anonymous access types.
20618 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20619 the literal in an unchecked conversion, because GCC 4.x needs a static
20620 value for a string bound.
20622 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20623 Hristian Kirtchev <kirtchev@adacore.com>
20625 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20626 components of the corresponding record, take into account component
20627 definitions that are access definitions.
20628 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20629 procedure is not considered a dispatching call and will be expanded
20632 2006-02-13 Javier Miranda <miranda@adacore.com>
20634 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20635 controlling argument of the dispatching call is an abstract interface
20636 class-wide type then we use it directly.
20637 Check No_Dispatching_Calls restriction.
20638 (Default_Prim_Op_Position): Remove the code that looks for the last
20639 entity in the list of aliased subprograms. This code was wrong in
20641 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20642 when the source is compiled with the No_Dispatching_Calls restriction.
20643 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20644 if we are compiling with restriction No_Dispatching_Calls.
20645 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20646 subprograms if we are compiling under No_Dispatching_Calls restriction.
20647 (Make_DT): Generate a dispatch table with a single dummy entry if
20648 we are compiling with the No_Dispatching_Calls restriction. In
20649 addition, in this case we don't generate code that calls to the
20650 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20651 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20652 of this subprogram if compiling with the No_Dispatching_Calls
20654 (Expand_Type_Conversion): Instead of using the actual parameter,
20655 the argument passed as parameter to the conversion function was
20656 erroneously referenced by the expander.
20657 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20658 Set_Predefined_Primitive_Op_Address and Set_Signature.
20659 (Expand_Dispatching_Call): Generate call to
20660 Get_Predefined_Prim_Op_Address for predefined primitives.
20661 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20662 predefined primitives.
20663 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20664 primitives we reserve one dummy entry to ensure that the tag does not
20665 point to some memory that is associated with some other object. In
20666 addition, remove all the old code that generated the assignments
20667 associated with the signature of the dispatch table and replace them
20668 by a call to the new subprogram Set_Signature.
20669 (Set_All_DT_Position): Change the algorithm because now we have a
20670 separate dispatch table associated with predefined primitive operations.
20671 (Expand_Interface_Conversion): In case of non-static offset_to_top
20672 add explicit dereference to get access to the object after the call
20673 to displace the pointer to the object.
20674 (Expand_Interface_Thunk): Modify the generation of the actual used
20675 in the calls to the run-time function Offset_To_Top to fulfil its
20677 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20679 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20681 * exp_dist.adb (Copy_Specification): For access parameters, copy
20682 Null_Exclusion flag, which will have been set for stream subprograms
20685 2006-02-13 Pascal Obry <obry@adacore.com>
20687 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20688 previous implementation was using the C runtime spawnve routine but
20689 the corresponding wait was using directly the Win32 API. This was
20690 causing some times a lock when waiting for an event using
20691 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20692 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20693 API fixes this problem.
20695 2006-02-13 Robert Dewar <dewar@adacore.com>
20697 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20702 * exp_pakd.ads: Fix typos in comments.
20704 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
20705 array reference that is an explicit dereference, mark the converted
20706 (packed) array reference as analyzed to prevent a forthcoming
20707 reanalysis from resetting its type to the original (non-packed) array

20711 Javier Miranda <miranda@adacore.com>
20712 Eric Botcazou <ebotcazou@adacore.com>
20714 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20715 Is_Predefined_Primitive_Operation): When
20716 searching for the predefined equality operator, verify that operands
20717 have the same type.
20718 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20719 for the last entity in the list of aliased subprograms. This code
20720 was wrong in case of renamings.
20721 (Set_Renamed_Subprogram): New procedure
20722 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20723 Exp_Type constant computed when entering this subprogram.

20728 side effect, unlike other attributes that are functions. (from code
20730 (Remove_Side_Effects): Expressions that involve packed arrays or records
20731 are copied at the point of reference, and therefore must be marked as
20732 renamings of objects.

20734 not a dispatching operation.
20737 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20738 elementary types in all cases.

20754 * g-catiio.adb (Sec_Number): New type used to compute the number of
20755 seconds since 1-1-1970.
20756 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20757 negative numbers (years, months...) it is better to have a Natural here.
20759 (Image) [Number]: Change parameter from Long_Integer to Number.
20760 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20761 overflow for dates past year 2038.
20763 2006-02-13 Matthew Heaney <heaney@adacore.com>
20765 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise

20777 * gnatcmd.adb (Rules_Switches): New table
20778 (Add_To_Rules_Switches): New procedure
20779 (GNATCmd): For command CHECK, put all options following "-rules" in the
20780 Rules_Switches table. Append these -rules switches after the -cargs
20783 2006-02-13 Robert Dewar <dewar@adacore.com>
20785 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20786 These two cases were generating incorrect output, and if this unit
20787 was built with checks on, generated a discriminant mismatch constraint
20790 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20791 Robert Dewar <dewar@adacore.com>
20793 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20794 view is an array type, indicate the component type as well, for
20795 navigation purposes.
20796 (Generate_Reference): Don't consider array ref on LHS to be a case
20797 of violating pragma Unreferenced.
20798 Do not give Ada 2005 warning except on real reference.
20800 2006-02-13 Vincent Celier <celier@adacore.com>
20802 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20803 main source, add switch -mdebug-main=_ada_ so that the executable can
20804 be debugged by the standard VMS debugger.
20805 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20806 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20807 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20808 of the last source, as the binding and linking phases are never
20810 Set all executable obsolete when rebuilding a library.
20812 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20815 2006-02-13 Javier Miranda <miranda@adacore.com>
20818 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20819 code to improve the error message reported when the program has
20820 declarations of abstract interface types and it is not compiled with
20821 the -gnat05 switch.
20822 (P_Access_Definition): Reorganize the code to improve the error
20823 message reported when the new Ada 2005 syntax for anonymous

20847 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20848 unknown, use the location of the project to report the error.
20849 (When_No_Sources): New global variable
20850 (Report_No_Ada_Sources): New procedure
20851 (Check): New parameter When_No_Sources. Set value of global variable
20853 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20854 (Get_Sources_From_File): Ditto
20855 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20858 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
20859 Call Prj.Proc.Process with parameter When_No_Sources.
20861 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
20862 Call Recursive_Check with parameter When_No_Sources.
20863 (Recursive_Check): New parameter When_No_Sources. Call itself and
20864 Prj.Nmsc.Check with parameter When_No_Sources.
20865 (Process): New parameter When_No_Sources. Call Check with parameter
20867 (Copy_Package_Declarations): New procedure to copy renamed parameters

20877 When removing nodes (attributes Source_Dirs, Source_Files,
20878 Source_List_File and package Naming), save the comments and attach the
20879 saved comments to the newly created nodes.
20880 Do not add a with clause for the naming package if one already exists.

20896 No_Return procedure with procedure that is not No_Return
20897 (Check_Dispatching_Call): Suppress the check for an abstract operation
20898 when the original node of an actual is a tag-indeterminate attribute
20899 call, since the attribute, which must be 'Input, can never be abstract.
20900 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
20901 call to the Input attribute (even when rewritten).
20902 (Propagate_Tag): Augment comment to indicate the possibility of a call
20903 to an Input attribute.
20905 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow

20915 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
20917 2006-02-13 Javier Miranda <miranda@adacore.com>
20919 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
20920 handles default-initialized components to keep separate the management
20921 of this feature but also avoid the unrequired resolution and
20922 expansion of components that do not have partially initialized
20924 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
20925 (Check_Bounds): Likewise.
20926 (Check_Length): Likewise.
20928 2006-02-13 Javier Miranda <miranda@adacore.com>
20929 Ed Schonberg <schonberg@adacore.com>
20931 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
20932 abstract interface type call analyze_and_resolve to expand the type
20933 conversion into the corresponding displacement of the
20934 reference to the base of the object.
20935 (Eval_Attribute, case Width): For systems where IEEE extended precision
20936 is supported, the maximum exponent occupies 4 decimal digits.
20937 (Accessibility_Message): Add '\' in 2-line warning message.
20938 (Resolve_Attribute): Likewise.
20939 (case Attribute_Access): Significantly revise checks
20940 for illegal access-to-subprogram Access attributes to properly enforce
20941 the rules of 3.10.2(32/2).
20942 Diagnose use of current instance with an illegal attribute.
20944 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
20946 (Enclosing_Generic_Unit): New function to return a node's innermost
20947 enclosing generic declaration node.
20948 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
20949 (Type_Access_Level): The accessibility level of anonymous acccess types
20950 associated with discriminants is that of the current instance of the
20951 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
20952 (Compile_Time_Constraint_Error): Handle case of conditional expression.
20953 (Kill_Current_Values_For_Entity): New function
20954 (Enter_Name): Change formal type to Entity_Id

20960 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
20961 Analyze_Compilation_Unit.
20962 Detect and warn on redundant with clauses detected in a package spec
20963 and/or body when -gnatwr is used.
20964 (Analyze_Context): Analyze config pragmas before other items
20965 (Install_Context_Items): Don't analyze config pragmas here
20966 (Install_Limited_Withed_Unit): Set limited entity of package in
20967 with_clause so that cross-reference information or warning messages on
20968 unused packages can be properly generated
20969 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
20970 has Error_Posted set. Prevent infinite loops in illegal programs.
20971 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
20972 to the point of the error test requiring the current unit to be private.
20973 This ensures that private with clauses are not exempted from the basic
20974 checking for being a descendant of the same library unit parent as a
20975 withed private descendant unit.
20976 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
20977 handle private with clauses properly, as well as to account for cases
20978 where the withed unit is a public descendant of a private ancestor
20979 (in which case the current unit must be a descendant of the private
20980 ancestor's parent). The spec comments were updated accordingly. Also,
20981 the old error message in this subprogram was replaced with error
20982 messages that mirror the errors tested and reported by
20983 Check_Private_Child_Unit.
20984 Parameter and variable names improved for readability.
20985 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20986 private as the precondition for calling
20987 Check_Private_Limited_Withed_Unit since that subprogram has been
20988 revised to test public units as well as private units.

20993 Javier Miranda <miranda@adacore.com>
20995 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20996 that Scope_Stack.First = 1.
20997 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20998 were not always properly handled previously.
20999 (Formal_Entity): Complete rewrite, to handle properly some complex case
21000 with multiple levels of parametrization by formal packages.
21001 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21002 to the corresponding derived type declaration for proper semantics.
21004 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21005 (Check_Component): Enforce restriction on components of
21006 unchecked_unions: a component in a variant cannot contain tasks or
21008 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21010 Add pragma Ada_2005 (synonym for Ada_05)
21011 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21012 were not always properly handled previously.
21013 Document that pragma Propagate_Exceptions has no effect
21014 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21015 (Set_Convention_From_Pragma): Check that if a convention is
21016 specified for a dispatching operation, then it must be
21017 consistent with the existing convention for the operation.
21018 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21019 longer required to specify an vtable-ptr component in the record. For
21020 compatibility reasons we leave the support for the previous definition.
21021 (Analyze_Pragma, case No_Return): Allow multiple arguments
21023 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21024 non-overrideen inherited operation with a controlling result as
21025 illegal only its implicit declaration comes from the derived type
21026 declaration of its result's type.
21027 (Check_Possible_Deferred_Completion): Relocate the object definition
21028 node of the subtype indication of a deferred constant completion rather
21029 than directly analyzing it. The analysis of the generated subtype will
21030 correctly decorate the GNAT tree.
21031 (Record_Type_Declaration): Check whether this is a declaration for a
21032 limited derived record before analyzing components.
21033 (Analyze_Component_Declaration): Diagnose record types not explicitly
21034 declared limited when a component has a limited type.
21035 (Build_Derived_Record_Type): Code reorganization to check if some of
21036 the inherited subprograms of a tagged type cover interface primitives.
21037 This check was missing in case of a full-type associated with a private
21039 (Constant_Redeclaration): Check that the subtypes of the partial and the
21040 full view of a constrained deferred constant statically match.
21041 (Mentions_T): A reference to the current type in an anonymous access
21042 component declaration must be an entity name.
21043 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21044 class_wide type to refer to full type, not to the incomplete one.
21045 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21046 available. Required to give support to the certified run-time.
21047 (Analyze_Component_Declaration): In case of anonymous access components
21048 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21049 (Process_Discriminants): For an access discriminant, use the
21050 discriminant specification as the associated_node_for_itype, to
21051 simplify accessibility checks.
21053 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21054 Javier Miranda <miranda@adacore.com>
21056 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21057 abstract interpretations on an operator, remove interpretations that
21058 yield Address or a type derived from it, if one of the operands is an
21060 (Try_Object_Operation.Try_Primitive_Operation,
21061 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21062 location when creating the new reference to a primitive or class-wide
21063 operation as a part of rewriting a subprogram call.
21064 (Try_Primitive_Operations): If context requires a function, collect all
21065 interpretations after the first match, because there may be primitive
21066 operations of the same type with the same profile and different return
21067 types. From code reading.
21068 (Try_Primitive_Operation): Use the node kind to choose the proper
21069 operation when a function and a procedure have the same parameter
21071 (Complete_Object_Operation): If formal is an access parameter and prefix
21072 is an object, rewrite as an Access reference, to match signature of
21073 primitive operation.
21074 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21075 by an expanded name with prefix Standard, when the operands are of an
21076 anonymous access type.
21077 (Remove_Abstract_Operations): If the operation is abstract because it is
21078 inherited by a user-defined type derived from Address, remove it as
21079 well from the set of candidate interpretations of an overloaded node.
21080 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21083 2006-02-13 Bob Duff <duff@adacore.com>
21085 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21086 redundant use clauses.
21087 In particular, if the scope of two use clauses overlaps, but one is not
21088 entirely included in the other, we should not warn. This can happen
21089 with nested packages.
21090 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21091 reported errors. The bug was reported when the compiler was built
21092 with assertions enabled.
21093 (Find_Type): If the node is a 'Class reference and the prefix is a
21094 synchronized type without a corresponding record, return the type
21097 2006-02-13 Javier Miranda <miranda@adacore.com>
21099 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21100 if this is the full-declaration associated with a private declaration
21101 that implement interfaces, then the private type declaration must be
21103 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21104 as aliased. The use of the 'access attribute is not available for such
21105 object (for this purpose the object should be explicitly marked as
21106 aliased, but being an anonymous type this is not possible).
21108 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21109 Robert Dewar <dewar@adacore.com>
21111 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21112 compilation unit is an elaboration scope.
21113 (Add_Task_Proc): Add '\' in 2-line warning message.
21114 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21116 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21117 Javier Miranda <miranda@adacore.com>
21119 * sem_type.adb (Write_Overloads): Improve display of candidate
21121 (Add_One_Interp): Do not add to the list of interpretations aliased
21122 entities corresponding with an abstract interface type that is an
21123 immediate ancestor of a tagged type; otherwise we have a dummy
21124 conflict between this entity and the aliased entity.
21125 (Disambiguate): The predefined equality on universal_access is not
21126 usable if there is a user-defined equality with the proper signature,
21127 declared in the same declarative part as the designated type.
21128 (Find_Unique_Type): The universal_access equality operator defined under
21129 AI-230 does not cover pool specific access types.
21130 (Covers): If one of the types is a generic actual subtype, check whether
21131 it matches the partial view of the other type.
21133 2006-02-13 Thomas Quinot <quinot@adacore.com>
21135 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21136 line. This is necessary to allow In_Extended_Main_Unit to provide
21137 correct results for itypes while writing out expanded source.
21138 (Close_File): No need to update the source_index_table here since it's
21139 now done for each line.
21141 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21142 Robert Dewar <dewar@adacore.com>
21144 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21145 preserve the source unit where the itype is declared, and prevent a

21155 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21158 2006-02-13 Bob Duff <duff@adacore.com>
21160 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21161 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21162 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21163 raise Constraint_Error.
21165 * s-vallli.adb (Scan_Long_Long_Integer): Call
21166 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21167 do not scan leading blanks and sign twice.
21168 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21169 raise Constraint_Error.
21171 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21172 Scan_Long_Long_Unsigned): Split out most of the processing from
21173 Scan_Long_Long_Unsigned out into
21174 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21175 This prevents scanning leading blanks and sign twice.
21176 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21179 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21180 out most of the processing from Scan_Unsigned out into
21181 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21182 This prevents scanning leading blanks and sign twice.
21184 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21185 use with Modular'Value attribute.
21186 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value

21384 * a-taster.ads, a-taster.adb: New files.
21386 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21387 link to the version that does nothing. This way the task termination
21388 routine is not executed twice for the environment task when finishing
21389 because of an unhandled exception.
21391 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21392 handler because of an unhandled exception.
21394 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

21400 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21401 non-tasking version of the soft link for task termination. We do
21402 nothing since if we are using the non-tasking version it
21403 means that the task termination functionality is not used.
21404 (Null_Finalize_Global_List): Add this null version for the procedure
21405 in charge of finalizing the global list for controlled objects.
21406 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21407 instead for handling run-time termination in a more flexible way.
21408 (Adafinal_NT): This new procedure will take care of finalizing the
21409 global list for controlled objects if needed, but no tasking
21412 * s-tarest.adb (Task_Lock): Do not try to lock again the
21413 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21414 some run-time operations.
21415 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21416 until all nested locks have been released.
21417 (Task_Wrapper): Call the fall-back task termination handler. It
21418 applies to all tasks but the environment task.
21419 (Finalize_Global_Tasks): Add the call for the task termination
21420 procedure for the environment task.
21421 (Task_Wrapper): suppress warnings around declaration of
21422 Secondary_Stack_Address.
21424 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21425 moved to the Common_ATCB record.
21426 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21427 Common_ATCB record.
21428 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21429 Common_ATCB record.
21431 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21432 Fall_Back_Handler, and Specific_Handler.
21434 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21435 defined in Ada.Task_Termination, to avoid circular dependencies.
21436 (Termination_Handler): Redefine this type here, alredy defined in
21437 Ada.Task_Termination, for avoiding circular dependencies.
21438 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21439 for storing task termination handlers. In addition,
21440 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21441 Common_ATCB because it is used by both the regular and the restricted
21443 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21444 Common_ATCB because it is used by both the regular and the restricted
21446 (Common_ATCB): Added a dynamic task analyzer field.
21448 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21449 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.

21451 tasks but the environment task.
21452 (Finalize_Global_Tasks): Call the task termination procedure for the
21453 environment task. The call to Finalize_Global_List is now performed
21454 using the soft links mechanism.
21455 (Task_Wrapper): added dynamic stack analysis.
21457 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21458 potentially blocking operations has been moved from
21459 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21460 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21461 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21462 this run-time check.
21464 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21465 of task termination procedure.
21466 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21467 link for the task termination procedure.

21508 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21509 to the specification because the frontend generates code that uses this
21511 (Set_Interface_Table): Add missing assertion.
21512 Update documentation describing the run-time structure.
21513 (Displace): New subprogram that displaces the pointer to the object
21514 to reference one of its secondary dispatch tables.
21515 (IW_Membership): Modified to use the new table of interfaces.
21516 (Inherit_TSD): Modified to use the new table of interfaces.
21517 (Register_Interface_Tag): Use the additional formal to fill the
21518 contents of the new table of interfaces.
21519 (Set_Interface_Table): New subprogram that stores in the TSD the

21534 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21535 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21536 record component containing the tag of the secondary dispatch table we
21537 have to use the Offset_To_Top run-time function to get this information;
21538 otherwise if the pointer to the base of the object has been displace
21539 we get a wrong value if we use the 'position attribute.
21541 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21542 all the calls to Expand_Interface_Thunk.
21543 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21544 interfaces; hence the call to Set_Interface_Table was clearly wrong.

21546 ensure that the interfaces implemented by the ancestors are placed
21547 at the header of the generated list.
21548 (Expand_Interface_Conversion): Handle the case in which the displacement
21549 associated with the interface conversion is not statically known. In
21550 this case we generate a call to the new run-time subprogram Displace.

21552 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
21553 Get_Tagged_Kind and Set_Tagged_Kind.
21554 (Tagged_Kind): New function that determines the tagged kind of a type
21555 with respect to limitedness and concurrency and returns a reference to

21558 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
21559 primary dispatch table for a type.

21561 secondary dispatch table respectively of a tagged type.
21563 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.

21574 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
21575 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
21576 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
21577 RE_TK_Tagged, RE_TK_Task.
21579 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
21580 Init_Secondary_Tags_Internal to allow its use with interface types and
21581 also to generate the code for the new additional actual required
21582 by Set_Offset_To_Top.
21583 (Build_Init_Statements): In case of components associated with abstract
21584 interface types there is no need to generate a call to its IP.
21585 (Freeze_Record_Type): Generate Select Specific Data tables only for
21587 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
21588 the bodies and specifications of the predefined primitive operations
21589 dealing with dispatching selects and abort, 'Callable, 'Terminated only
21590 for concurrent types.
21592 * exp_sel.ads, exp_sel.adb: New files.
21594 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
21595 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
21596 properly protected objects and attach handler in the case of the
21597 restricted profile.
21598 Move embeded package Select_Expansion_Utilities into a separate external
21600 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
21601 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
21602 (Build_K, Build_S_Assignment): New subprograms, part of the select
21603 expansion utilities.

21606 where the trigger is a dispatching procedure of a limited tagged type.
21608 2005-12-09 Olivier Hainque <hainque@adacore.com>
21610 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
21611 pointer initialization values. Make a SAVE_EXPR instead. Add comments
21612 about the use and expansion of SAVE_EXPRs in the various possible
21613 renaming handling cases.
21614 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
21615 abusing DECL_FCONTEXT.

21715 covered by the tag of the source.
21717 2005-12-09 Robert Dewar <dewar@adacore.com>
21719 * exp_imgv.adb (Expand_Image_Attribute): Generate extra boolean

21734 component associated with the secondary table of an abstract interface
21735 type, return the entity associated with such abstract interface type.
21736 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
21737 base type to create anonymous subtype, because entity may be a locally
21738 declared subtype or generic actual.
21739 (Find_Interface): New subprogram that given a tagged type and one of its
21740 component associated with the secondary table of an abstract interface
21741 type, return the entity associated with such abstract interface type.
21743 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
21744 conversion cannot be handled at compile time. In this case we pass this
21745 information to the expander to generate the appropriate code.

21780 copied component does not have a known static Esize, then reset
21781 the size and positional fields of the new component.
21782 (Analyze_Component_Declaration): A limited component is
21783 legal within a protected type that implements an interface.
21784 (Collect_Interfaces): Do not add to the list the interfaces that
21785 are implemented by the ancestors.
21786 (Derived_Type_Declaration): If the parent of the full-view is an
21787 interface perform a transformation of the tree to ensure that it has
21788 the same parent than the partial-view. This simplifies the job of the
21789 expander in order to generate the correct object layout, and it is
21790 needed because the list of interfaces of the full-view can be given in
21792 (Process_Full_View): The parent of the full-view does not need to be
21793 a descendant of the parent of the partial view if both parents are
21795 (Analyze_Private_Extension_Declaration): If declaration has an explicit
21796 "limited" the parent must be a limited type.

21810 (Process_Full_View): Improve the check for the "no hidden interface"
21811 rule as defined by AI-396.
21813 2005-12-09 Robert Dewar <dewar@adacore.com>
21815 * freeze.adb (Freeze_Record_Type): Only test for useless pack on record
21816 types, not on record subtypes.
21817 (Freeze_Entity): Code cleanup. Add barrier to the loop
21818 that generates the references for primitive operations. This allows to
21819 remove an unnecessary exception handler.

21870 available user-specified stream attributes on limited parameters to
21871 also test the type directly rather than only its underlying type (for
21872 Ada 95) and, in the case of Ada 2005, to check that the user-specified
21873 attributes are visible at the point of the subprogram declaration.
21874 For Ada 2005, the error message is modified to indicate that the
21875 type's stream attributes must be visible (again, only for -gnat05).

21907 types use the corresponding record type. This was not needed before
21908 the implementation of Ada 2005 synchronized types because
21909 concurrent types were never tagged types in Ada 95.

22037 * socket.c: Add extern int h_errno for rtems since networking header
22038 files are not available at this point in a tool bootstrap. Newlib

22042 Roger Sayle <roger@eyesopen.com>
22045 * misc.c (internal_error_function): Don't use vsprintf to format
22046 the error message text, instead use pp_format_text and the new

22057 * trans.c (gnat_gimplify_expr, case ADDR_EXPR): Always make
22058 a temporary if taking the address of something that is neither
22059 reference, declaration, or constant, since the gimplifier
22060 can't handle that case.
22062 2005-11-17 Laurent Guerby <laurent@guerby.net>
22065 * s-auxdec-empty.ads, s-auxdec-empty.adb: New files.

22132 * gen-soccon.c: Complete value expansion should not be performed on
22133 TARGET, as it has the form of a math expression, and some components
22134 may be platform-defined macros.
22135 For VxWorks, generate the OK and ERROR values.
22136 New constants giving the sizes of the components of C struct timeval.
22138 2005-11-14 Robert Dewar <dewar@adacore.com>

22142 * types.ads: Include All_Checks in Suppress_Array
22144 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as
22145 not(a=b), since we no longer do this rewriting, and hence it is not
22147 (Elaboration_Checks_Suppressed): Add special casing to
22148 deal with different cases of static and dynamic elaboration checks (all
22149 checks does not count in the first case, but does in the second).
22150 (Expr_Known_Valid): Do not assume that the result of any arbitrary
22151 function call is valid, since this is not the case.
22152 (Ensure_Valid): Do not apply validity check to a real literal
22153 in a universal or fixed context
22155 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
22156 elementary types using the operator in standard. It is cleaner not to
22157 modify the programmers intent, especially in the case of floating-point.
22158 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
22159 it did not matter because we always rewrote a/=b to not(a=b).
22160 (Expand_Allocator_Expression): For an allocator expression whose nominal
22161 subtype is an unconstrained packed type, convert the expression to its
22162 actual constrained subtype.
22163 Implement warning for <= or >= where < or > not possible
22164 Fix to Vax_Float tests (too early in many routines, causing premature
22165 Vax_Float expansions.
22167 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Allow this pragma
22168 to be used with packages and generic packages as well as with
22170 (Suppress): Set All_Checks, but not Elaboration_Check, for case
22171 of pragma Suppress (All_Checks)
22172 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
22173 a string literal for precise control over warnings.
22174 Avoid raise of pragma in case of unrecognized pragma and just return
22177 * sem_prag.ads: Minor reformatting
22179 * switch-c.adb (Scan_Front_End_Switches): Replace "raise Bad_Switch;"
22180 with call to new procedure Bad_Switch. Call Scan_Pos with new parameter
22181 Switch. Do not handle any exception.
22182 Include -gnatwx as part of -gnatg (warn on redundant parens)
22183 Allow optional = after -gnatm
22184 (Scan_Front_End_Switches): The -gnatp switch sets All_Checks, but no
22185 longer sets Elaboration_Checks.
22186 Code to set warning mode moved to Sem_Warn
22187 so that it can be shared by pragma processing.

22314 we are not defining the type.
22315 <E_Record_Type>: Likewise.
22316 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22317 to get advantage of the new maybe_stabilize_reference interface, to
22318 ensure that what we reference is indeed stabilized instead of relying
22319 on assumptions on what the stabilizer does.
22320 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22321 type imported through a limited_with clause, use its non-limited view.
22322 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

22327 before early-returning for certain types when code generation is
22329 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

22331 that we are not defining.
22332 (elaborate_expression_1): Do not create constants when creating
22333 variables needed by the debug info: the dwarf2 writer considers that
22334 CONST_DECLs is used only to represent enumeration constants, and emits
22336 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22337 object with an address clause into an indirect reference, drop the
22338 initializing expression.

22350 subtype to build an actual type with bounds template.
22351 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22352 is provided by the front-end, use that subtype to compute the size of
22353 the deallocated object.

22355 check for a potential violation of a No_Elaboration_Code restriction.

22361 without need to check for the success indication.

22363 pass false instead of 0 as the FORCE argument which is a bool.
22364 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22365 attached to a renaming pointer has been properly stabilized, as no such
22366 object is attached otherwise.

22368 function uses the "target pointer" return mechanism.
22369 Reinstate conversion of the actual to the type of the formal
22370 parameter before any other specific treatment based on the passing
22371 mechanism. This turns out to be necessary in order for PLACEHOLDER
22372 substitution to work properly when the latter type is unconstrained.

22376 (maybe_stabilize_reference): New function, like gnat_stabilize_reference

22380 * utils2.c (gnat_build_constructor): Only sort the fields for possible
22381 static output of record constructor if all the components are constant.
22382 (gnat_build_constructor): For a record type, sort the list of field
22383 initializers in increasing bit position order.
22384 Factor common code to build a storage type for an unconstrained object
22385 from a fat or thin pointer type and a constrained object type.
22386 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22387 types variants, and process special cases of VIEW_CONVERT expressions
22388 as their NOP_EXPR counterpart to ensure we get to the
22389 CORRESPONDING_VARs associated with CONST_DECls.
22390 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22391 on the right-hand side.

22398 extracting the object if converting to a type variant.
22399 (create_var_decl): When a variable has an initializer requiring code
22400 generation and we are at the top level, check for a potential violation
22401 of a No_Elaboration_Code restriction.
22402 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
22403 SIZE and SIZE_UNIT which we need for later back-annotations.

22406 is an unchecked union.

22408 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
22409 main variant, just replace the VIEW_CONVERT_EXPR.

22545 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22546 for task component, in the case of a limited aggregate. The enclosed

22586 access to unconstrained packed array type, annotate the dereference
22587 with an actual subtype so GIGI can make a correct size computation.
22588 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22589 'Unrestricted_Access, if the designated type is an interface we
22590 add a type conversion to force the displacement of the pointer
22591 to the secondary dispatch table.
22592 Use Universal_Real instead of Long_Long_Float when we need a high
22593 precision float type for the generated code (prevents gratuitous
22594 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22595 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22596 'Terminated for task interface class-wide objects. Generate a call to
22597 the predefined dispatching routine used to retrieve the _task_id from
22598 a task corresponding record.

22624 for any entity whose value is known from the condition of the first
22626 (Expand_N_Return_Statement): When returning a mutable record, convert
22627 the return value into its actual subtype in order to help the backend
22628 to return the actual size instead of the maximum. This is another
22629 aftermath of not returning mutable records on the sec-stack anymore.

22632 handling of error msg for suspicious reverse range iteration.

22960 leave it more clear.
22961 (Analyze_Type_Declaration): If type has previous incomplete tagged

23018 whose default is abstract because the object type itself is abstract.
23019 (Find_Type): If the type is incomplete and appears as the prefix of a
23020 'Class reference, it is tagged, and its list of primitive operations
23021 must be initialized properly.

23051 statement to inhibit warning.
23052 (Resolve_Unary_Op): Do not produce a warning when
23053 processing an expression of the form -(A mod B)

24096 position set is provided, we compute one in order to reduce the maximum
24097 length of the keys. This computation first selects a character
24098 position between 1 and the minimum length of the keys in order to
24099 avoid reducing one of the keys to an empty string.
24100 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24101 does not converge. The initialization procedure now comes with a

24235 Ed Schonberg <schonberg@adacore.com>
24236 Robert Dewar <dewar@adacore.com>
24238 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24239 'Address attribute reference with an overloaded prefix, use the
24240 location of the prefix (not the location of the attribute reference) as
24241 the error location.
24242 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24243 a function renaming thereof, is a valid prefix for 'Size (where it is
24244 intepreted as a function call).
24245 (Statically_Denotes_Entity): New predicate to determine whether the
24246 prefix of an array attribute can be considered static.
24249 (Eval_Attr): Fix failure to evaluate Component_Size for
24250 unconstrained arrays (resulted in wrong value in packed case, since
24251 back end cannot handle this case)
24253 2005-09-01 Robert Dewar <dewar@adacore.com>
24255 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24256 error msgs for most common cases.
24257 Use new errout insertion char < (conditional warning)
24259 2005-09-01 Javier Miranda <miranda@adacore.com>
24260 Ed Schonberg <schonberg@adacore.com>
24262 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24263 become local to the whole package.
24264 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24265 the package was already analyzed the new algorithm "replaces" the
24266 real entities by the shadow ones. This is required to ensure that
24267 the order of these entities in the homonym chains does not change;
24268 otherwise we can have undefined references at linking time because
24269 in case of conflicts the external name of the entities will have
24270 a suffix that depends on the order of the entities in the chain.
24271 (Remove_Limited_With_Clause): Complementary code that completes the
24272 new algorithm and replaces the shadow entities by the real ones.
24273 (Install_Limited_Withed_Unit): When unchaining entities before the
24274 installation of the shadow entities, only regular entities of the
24275 public part must be taken into account. This is required to
24276 keep this routine in synch with the work done by Remove_Limited_
24278 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24279 even if unit is analyzed, because the analysis of the unit is
24280 idempotent in any case, and the limited view of the unit may have to
24281 be installed for proper visibility.
24282 (Expand_Limited_With_Clause): Even if the unit in the implicit
24283 with_clause has been analyzed already, a limited view of the package
24284 must be built for the current context, if it does not exist yet.
24286 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24287 Javier Miranda <miranda@adacore.com>
24288 Gary Dismukes <dismukes@adacore.com>
24290 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24291 defining entity for the instance body, make a new defining identifier
24292 rather than copying the entity of the spec, to prevent accidental
24293 sharing of the entity list.
24294 (Check_Private_View): When exchanging views of private types, build the
24295 list of exchanged views as a stack, to ensure that on exit the exchanges
24296 are undone in the proper order.
24297 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24298 Restore the compilation environment in case of instantiation_error.
24299 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24300 for an anonymous access result.
24301 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24302 (Formal_Entity): Handle properly the case of a formal package that
24303 denotes a generic package renaming.
24305 2005-09-01 Thomas Quinot <quinot@adacore.com>
24307 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24308 clause if the array aggregate is surrounded by parentheses.
24310 2005-09-01 Cyrille Comar <comar@adacore.com>
24311 Gary Dismukes <dismukes@adacore.com>
24312 Ed Schonberg <schonberg@adacore.com>
24313 Javier Miranda <miranda@adacore.com>
24315 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24317 to check if a type is Constrained in cases related to code generation
24318 (rather than semantic checking) since otherwise we do not generate
24319 similar code for mutable private types depending if their
24320 discriminants are visible or not.
24321 (Check_Abstract_Overriding): Do not complain about failure to override
24322 the primitive operations used in dispatching selects since they will
24323 always be overriden at the freeze point of the type.
24324 (Access_Definition): Separate out handling for resetting the scope
24325 of an anonymous access function result type. Retrieve the scope
24326 of the associated function rather than using Current_Scope, which
24327 does not have a consistent value (depends on whether we're in the
24328 middle of analyzing formal parameters). Add ??? comment about
24329 finding a cleaner way to handle the special cases of scope setting.
24330 (Process_Incomplete_Dependents): A protected operation is never a
24331 dispatching operation (only its wrapper may be).
24332 (Build_Derived_Record_Type): In case of tagged private types that
24333 implement interfaces add derivation of predefined primitive
24335 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24336 by two parameters that are used in case of derivation from abstract
24337 interface types: No_Predefined_Prims is used to avoid the derivation
24338 of predefined primitives from the interface, and Predefined
24339 Prims_Only is used to complete the derivation predefined primitives
24340 in case of private tagged types implementing interfaces.
24341 Fix typo in comments
24342 (Find_Interface_In_Descendant): Protect the frontend against
24343 wrong code with large circularity chains.
24344 (Is_Private_Overriding): Add support for entities overriding interface
24345 subprograms. The test failed because Entities associated with overriden
24346 interface subprograms are always marked as hidden (and used to build
24347 the secondary dispatch table); in this case the overriden entity is
24348 available through the field abstract_interface_alias (cf. override_
24349 dispatching_operation)
24350 (Access_Definition): Set the scope of the type to Current_Scope for the
24351 case of a function with an anonymous access result type.
24352 (Access_Subprogram_Declaration): Handle creation of the type entity for
24353 an access-to-function type with an anonymous access result.
24354 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24355 in handling for N_Access_Function_Definition.
24356 (Analyze_Subtype_Declaration): Modify the text of error message.
24357 (Derived_Type_Declaration): Modify the text of error message.
24358 (Process_Subtype): Modify the text of error message plus cleanup
24359 of one redundant error message.
24360 (Analyze_Component_Declaration): Code cleanup.
24361 (Analyze_Object_Declaration): Code cleanup.
24362 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24363 attribute in case of access types. Code cleanup.
24364 (Array_Type_Declaration): Code cleanup.
24365 (Process_Discriminants): Create the new null-excluding itype
24366 if required. Code cleanup.
24367 (Process_Subtype): Create the new null-excluding itype if
24368 required. Code cleanup.
24369 (Build_Derived_Record_Type): Code cleanup to avoid calling
24370 twice the subprogram derive_subprograms in case of private
24371 types that implement interfaces. In this particular case the
24372 subprogram Complete_Subprograms_Derivation already does the
24373 job associated with the second call.
24375 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24376 conversion to the full view when generating an operation for a
24377 discriminant whose type may currently be private.
24379 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24380 Javier Miranda <miranda@adacore.com>
24382 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24383 V (Obj.F), the rewriting does not involve the indexed component, but
24384 only the selected component itself.
24385 Do not apply the transformation if the analyzed node is an actual of a
24386 call to another subprogram.
24387 (Complete_Object_Operation): Retain the entity of the
24388 dispatching operation in the selector of the rewritten node. The
24389 entity will be used in the expansion of dispatching selects.
24390 (Analyze_One_Call): Improve location of the error message associated
24392 (Analyze_Selected_Component): No need to resolve prefix when it is a
24393 function call, resolution is done when parent node is resolved, as
24395 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24396 when attempting to resolve a call transformed from its object notation.
24397 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24398 of the argument list for each interpretation of the operation.
24399 (Try_Object_Operation): The designated type of an access parameter may
24400 be an incomplete type obtained through a limited_with clause, in which
24401 case the primitive operations of the type are retrieved from its full
24403 (Analyze_Call): If this is an indirect call, and the return type of the
24404 access_to_subprogram is incomplete, use its full view if available.
24406 2005-09-01 Javier Miranda <miranda@adacore.com>
24407 Gary Dismukes <dismukes@adacore.com>
24409 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24410 access types the null-exclusion and access-to-constant attributes must
24412 (Analyze_Return_Statement): When the result type is an anonymous access
24413 type, apply a conversion of the return expression to the access type
24414 to ensure that appropriate accessibility checks are performed.
24415 (Analyze_Return_Type): For the case of an anonymous access result type,
24416 generate the Itype and set Is_Local_Anonymous_Access on the type.
24417 Add ??? placeholder for check to disallow returning a limited object
24418 in Ada 2005 unless it's an aggregate or a result of a function call.
24419 Change calls from Subtype_Mark to Result_Definition.
24420 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24421 Result_Definition in call to Make_Function_Specification.
24422 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24423 Set_Result_Definition.
24424 (Make_Inequality_Operator): Change formal Subtype_Mark to
24425 Result_Definition in call to Make_Function_Specification.
24426 (Process_Formals): Create the new null-excluding itype if required.
24427 (New_Overloaded_Entity): For an entity overriding an interface primitive
24428 check if the entity also covers other abstract subprograms in the same
24429 scope. This is required to handle the general case, that is, overriding
24430 other interface primitives and overriding abstract subprograms inherited
24431 from some abstract ancestor type.
24432 (New_Overloaded_Entity): For an overriding entity that comes from
24433 source, note the operation that it overrides.
24434 (Check_Conformance, Type_Conformant): Addition of one new formal
24435 to skip controlling formals in the analysis. This is used to
24436 handle overloading of abstract interfaces.
24437 (Base_Types_Match): Add missing case for types imported from
24438 limited-with clauses
24439 (New_Overloaded_Entity): Add barrier to protect the use of
24440 the "alias" attribute.
24442 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24444 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24445 verify that the procedure and the entry are mode conformant.
24446 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24447 as a different operator, which is often a cut-and-paste error.
24449 2005-09-01 Javier Miranda <miranda@adacore.com>
24450 Ed Schonberg <schonberg@adacore.com>
24452 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24453 used in controlling parameters exclude null because it is necessary to
24454 read the tag to dispatch, and null has no tag.
24455 (Override_Dispatching_Operation): If the previous operation is inherited
24456 from an interface, it becomes hidden and does not participate in later
24459 2005-09-01 Javier Miranda <miranda@adacore.com>
24460 Ed Schonberg <schonberg@adacore.com>
24461 Gary Dismukes <dismukes@adacore.com>
24463 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24464 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24465 the expander will generate the corresponding run-time check to evaluate
24467 (Resolve_Call): Check for legal type of procedure name or prefix that
24468 appears as a trigger in a triggering alternative.
24469 (Valid_Conversion): If expression is ambiguous and the context involves
24470 an extension of System, remove System.Address interpretations.
24471 (Resolve_Qualified_Expression): Reject the case of a specific-type
24472 qualification applied to a class-wide argument. Enhance comment
24473 to explain checking of Original_Node.
24474 (Resolve_Type_Conversion): The location of the error message was not
24475 general enough to handle the general case and hence it has been removed.
24476 In addition, this patch improves the text of the message.
24477 (Resolve_Type_Conversion): Add missing support for access to interface
24479 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24480 do not expand if the expression is the actual in a call, because proper
24481 expansion will take place when the call itself is expanded.
24482 (Resolve_Allocator): If the context is an unchecked conversion, the
24483 allocator inherits its storage pool, if any, from the target type of
24486 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24487 Javier Miranda <miranda@adacore.com>
24489 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24490 inherited interface operation that has an implementation, use the
24491 implementation to avoid spurious ambiguities.
24492 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24493 use the Corresponding_Record_Typ attribute to look for the interface
24494 because it is set by the expander (and hence it is not always
24495 available). For this reason we traverse the list of interfaces
24496 (available in the parent of the concurrent type).
24497 (Interface_Present_In_Ancestor): Handle entities from the limited view
24499 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24501 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24502 from the list of required components.
24503 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24504 primitive procedure of a limited interface with a controlling first
24506 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24508 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24509 capture if it is generated in the second operand of a short-circuit
24511 Do not capture values for variables with address clauses.
24512 (Is_Object_Reference): Treat a function call as an object reference only
24513 if its type is not Standard_Void_Type.
24515 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24517 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24518 to a variable that is statically known to be constant.
24520 2005-09-01 Geert Bosch <bosch@adacore.com>
24521 Robert Dewar <dewar@adacore.com>
24523 * ttypef.ads (VAXDF_Safe_First): Use correct value for constant.
24524 (VAXGF_Safe_First): Idem.
24526 2005-09-01 Robert Dewar <dewar@adacore.com>
24527 Arnaud Charlet <charlet@adacore.com>
24529 * g-dirope.ads: Minor reformatting
24530 Document that bounds of result of Base_Name match the input index
24532 Add documentation on environment variable syntax for Expand_Path
24534 * gnat_ugn.texi: Update documentation to include mention of -m switches
24535 Document new treatment of wide characters in max line length
24537 Remove -gnatL/-gnatZ switches, no longer used.
24538 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24541 * gnat_rm.texi: Add doc for two argument form of pragma
24542 Float_Representation.
24543 Add documentation for pragma No_Strict_Aliasing
24544 Add note that explicit component clause overrides pragma Pack.
24545 Add documentation of pragma Debug_Policy

25300 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25301 longer protected objects. They have been replaced by lower-level
25302 suspension objects made up by a mutex and a condition variable (or
25303 their equivalent given a particular OS) plus some internal data to
25304 reflect the state of the suspension object.
25305 (Initialize, Finalize): Add this initialization procedure for
25306 Suspension_Object, which is a controlled type.
25307 (Finalize): Add the finalization procedure for Suspension_Object,
25308 which is a controlled type.
25310 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25311 Ada.Synchronous_Task_Control because there is no longer a need for a
25312 VxWorks specific version of this package. Target dependencies
25313 has been moved to System.Task_Primitives.Operations.
25315 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25317 (InitializeCriticalSection, EnterCriticalSection,
25318 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25319 pCriticalSection by an anonymous access type so that we avoid problems
25320 of accessibility to local objects.

25327 set the environment task mask here.
25328 (Current_State): Add this function that returns the state of the
25330 (Set_False): Add this procedure that sets the state of the suspension
25332 (Set_True): Add this procedure that sets the state of the suspension
25333 object to True, releasing the task that was suspended, if any.
25334 (Suspend_Until_True): Add this procedure that blocks the calling task
25335 until the state of the object is True. Program_Error is raised if
25336 another task is already waiting on that suspension object.
25337 (Initialize): Add this procedure for initializing the suspension
25338 object. It initializes the mutex and the condition variable which are
25339 used for synchronization and queuing, and it sets the internal state
25341 (Finalize): Add this procedure for finalizing the suspension object,
25342 destroying the mutex and the condition variable.

25347 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
25348 which provides a low-level abstraction (using operating system
25349 primitives) for Ada.Synchronous_Task_Control.
25350 This object is made up by a mutex (for ensuring mutual exclusion), a
25351 condition variable (for queuing threads until the condition is
25352 signaled), a Boolean (State) indicating whether the object is open,
25353 and a Boolean (Waiting) reflecting whether there is a task already
25354 suspended on this object.

25619 type derivation of private tagged types implementing interfaces.
25620 In this case some interface primitives may have been overriden

25710 * i-cpp.ads, i-cpp.adb:
25711 This package has been left available for compatibility with previous
25712 versions of the frontend. As part of the new layout this is now a

25766 access to subprograms must be recursive.
25767 (Is_Unchecked_Conversion): Improve the test that recognizes
25768 instantiations of Unchecked_Conversion, and allows them in bodies that
25769 are to be inlined by the front-end. When the body comes from an

25792 object or component (that is, when Is_Local_Anonymous_Access is true).
25793 Prevent the special checks for conversions of access discriminants in
25794 the case where the discriminant belongs to a nonlimited type, since
25795 such discriminants have their accessibility level defined in the same
25796 way as a normal component of an anonymous access type.
25797 (Resolve_Allocator): When an allocator's designated type is a class-wide
25798 type, check that the accessibility level of type given in the
25799 allocator's expression or subtype indication is not statically deeper

25819 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
25820 check on possible violation of restriction No_Direct_Boolean_Operators

26124 the "simple_choice" member in a variant record, in accordance with the
26125 description in the package spec: the information output for a constant
26126 should be "S number", not "SS number".
26127 (Get_Encoded_Name): Return at once if not generating code. Avoids name

26827 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead

26966 the node as a call once the context identifies the interpretation of
26967 the prefix whose call yields the context type.
26968 (Valid_Conversion): For the case of a conversion between
26969 local access-to-subprogram types, check subtype conformance using
26970 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more

27646 These subprogram have been removed because the attribute
27647 Task_Body_Procedure has been moved to the corresponding task type
27648 or task subtype entity to leave a field free to store the list
27649 of interfaces implemented by a task (for AI-345)

27764 Comes_From_Generic, to recognize accurately that the parent type in a
27765 derived type declaration can be traced back to a formal type, because
27766 it is one or is derived from one, or because its completion is derived
27768 (Constrain_Component_Type): If component comes from source and has no
27769 explicit constraint, no need to constrain in in a subtype of the

27802 that come from packed arrays).
27803 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27804 renamed entity is an inherited operation, re-expand the call using the
27805 original operation, which is the one to call.
27806 Detect attempt to inline parameterless recursive subprogram.
27807 (Represented_As_Scalar): Fix to work properly with private types
27808 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27809 accurate estimate. Yields True in far fewer cases than before,
27810 improving the quality of code that depends on this test.
27812 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27813 over both visible and private declarations to remove them from tree,
27814 and mark subprograms declared in package as eliminated, to prevent
27815 spurious use in subsequent compilation of generic units in the context.
27817 * exp_util.ads: Minor cleanup in variable names
27819 * sem_eval.ads, sem_eval.adb: Minor reformatting
27820 (Compile_Time_Known_Bounds): New function
27822 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27824 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27825 determining whether an unchecked conversion is needed for the argument
27826 of an initialization call.
27828 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27830 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27831 that appears in the instantiation rather than the internal subtype
27832 generated in the wrapper package, to avoid anomalies in gigi when the
27833 target is derived from a private type whose full view is an access type.
27835 2005-03-15 Robert Dewar <dewar@adacore.com>
27837 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27839 Add documentation to replace the use of this flag
27840 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27843 2005-03-15 Thomas Quinot <quinot@adacore.com>
27845 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27846 here from exp_attr so it can be shared between exp_attr and exp_dist.
27847 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27848 all TSS names, not a subset thereof, and the previous name introduced
27849 an unnecessarily confusion that a distinction might exist between
27850 "OK" TSS names and some "not OK" TSS names.
27852 2005-03-15 Doug Rupp <rupp@adacore.com>
27854 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27857 2005-03-15 Pascal Obry <obry@adacore.com>
27858 Eric Botcazou <ebotcazou@adacore.com>
27862 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
27863 when IN_RTS. This is to work around a bootstrap path problem.
27865 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
27866 table and pass it to __gnat_install_SEH_handler().
27867 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
27869 * lang.opt: Fix specification of -fRTS=.
27871 2005-03-15 Doug Rupp <rupp@adacore.com>
27872 Bernard Banner <banner@adacore.com>
27873 Vincent Celier <celier@adacore.com>
27874 Arnaud Charlet <charlet@adacore.com>
27877 This change works fine when gnatlib is built from the gcc directory,
27878 but does not work when using the libada Makefile, since GCC_FOR_TARGET
27879 is not passed to ada/Makefile.in, so more work is needed by a
27880 Makefile/configure expert.
27882 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
27883 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
27884 Setup gnatlink switch -M for x86_64 linux, as it is already setup
27886 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
27887 Run ranlib on libgccprefix.a
27888 Define PREFIX_OBJS for Darwin, to build libgccprefix.
27889 (ADA_INCLUDE_SRCS): Split Ada packages.
27891 2005-03-15 Robert Dewar <dewar@adacore.com>
27893 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
27895 * impunit.adb: Add GNAT.UTF_32
27897 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
27899 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
27900 now uses GNAT.UTF_32).
27902 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
27903 capabilities for categorizing characters using Unicode categories
27905 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27907 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
27908 instantiation that has been rewritten as a package body, retrieve spec
27909 to generate proper name for implicit_with_clause.
27910 (Install_Parents): Recognize a parent that is an instantiation but has
27911 been rewritten as a package declaration during analysis.
27913 2005-03-15 Javier Miranda <miranda@adacore.com>
27914 Ed Schonberg <schonberg@adacore.com>
27916 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
27917 parameter reported some error we immediately return. This improves the
27918 behaviour of the frontend in case of errors.
27919 (Install_Parent, Remove_Parent): Introduce new flag
27920 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
27921 ancestor of a generic child unit, when the child is being instantiated.
27922 (Inline_Instance_Body): If we are compiling the private
27923 part or the body of a child unit, restore the proper visibility of the
27924 parents after compiling the instance body.
27926 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27927 Javier Miranda <miranda@adacore.com>
27930 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
27931 of a private type, in which case it is underlying_type that denotes
27932 the proper task. Also modified to use the new entity attribute
27933 that is directly available in the task type and task subtype entities
27934 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
27935 arrays when other dimensions than the first are constrained by
27936 discriminants of an enclosing record.
27937 (Insert_Explicit_Dereference): If the prefix is an indexed component or
27938 a combination of indexed and selected components, find ultimate entity
27939 and generate the appropriate reference for it, to suppress spurious
27941 (Note_Possible_Modification): If an entity name has no entity, return.
27942 (Is_Variable): A function call never denotes a variable.
27943 (Requires_Transient_Scope): For record types, recurse only on
27944 components, not on internal subtypes that may have been generated for
27945 constrained components.
27947 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27949 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
27950 Eliminated as candidates for resolution. Both efficient, and avoids
27951 anomalies with operators declared in deleted code.
27952 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
27953 expansion is disabled (as when compiling a generic) to prevent spurious
27954 warnings on prefixes of selected components.
27956 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27958 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
27959 attached to a list before checking whether it appears in the private
27960 declarations of the current package.
27961 (Make_Inequality_Operator): Insert declaration in proper declarative
27962 list rather than just setting the Parent field, so that
27963 Is_Private_Declaration can handle it properly.
27965 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27967 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
27968 a renaming a body, check that the renamed subprogram in not intrinsic.
27969 (Find_Direct_Name): If several use_visible entities hide
27970 each other, and the context is a predefined file compiled through
27971 rtsfind, keep only the entity that comes from a predefined file.
27973 2005-03-15 Geert Bosch <bosch@adacore.com>
27975 * s-fatgen.adb (Valid): Extend special exceptions to account for long
27976 long float padding to also cover AMD64 and IA64.
27978 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27980 * s-imgwch.adb: Add with and use of Interfaces.
27981 (Img_Wide_Character): Change type of Val to Unsigned_16.

28036 as these may cause generated code to not conform to Ada semantics.
28037 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

28295 new reserved words of Ada 2005: Tok_Interface, Tok_Overriding
28296 and Tok_Synchronized.
28298 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
28299 "dispatching" rather than "primitive" operations, since dispatching
28300 calls are now allowed to abstract formal subprograms (which are not

28303 (Resolve_Slice): If the prefix is an access to an unconstrained array,
28304 compute the actual subtype of the designated object to impose the proper
28306 (Resolve_Selected_Component): Do not insert an access check if the
28307 prefix is an access type: such a node is expanded into an explicit
28308 dereference, on which the access check is performed anyway. Removes
28309 expensive duplicate checks.
28310 (Resolve_Call): Use new flag Is_Obsolescent and field
28311 Obsolescent_Warning so that pragma Obsolescent works on library
28313 Add support for wide wide character type
28314 (Resolve_Allocator): Replace the error message on wrong null-exclusion
28315 value by a warning message.
28316 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
28317 as fixed-point, and one of the operands is non-static and universal, it
28318 can only be an illegal exponentiation operation, in which case there is
28319 no real value to retrieve.
28321 * exp_strm.adb: Add support for wide wide character type
28322 (Build_Elementary_Input_Call): Compute the size of the stream element by

28360 "not in" for test of N_Formal_Subprogram_Declaration (which is now a
28362 (Unit_Declaration_Node): Ditto.
28363 (Is_Variable_Prefix): For the case of an indexed component whose prefix
28364 has a packed array type, the prefix has been rewritten into a type
28365 conversion. Determine variable-ness from the converted expression.
28366 Handle wide wide character cases.

28370 * stringt.ads, stringt.adb: Handle full UTF-32 range.
28371 Remove ["0A"] from comment, since it can look like a line terminator.
28372 Currently we don't permit this, but this is under discussion by the
28373 ARG, and it is easy enough to use a different example.
28375 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
28376 handling UTF-32 encoding for wide wide character.

28395 wrong null-exclusion value by a warning message.
28396 (Enable_Range_Check): Do range check if the prefix is an
28397 explicit dereference whose designated object is an unconstrained array.
28398 Current algorithm for removing duplicate checks is over-eager in this

28426 * exp_disp.ads, exp_disp.adb (Make_DT): Generate code that moves the
28427 pointer to the base of the dispatch table.
28428 Minor changes to comments.
28429 (Controlling_Type): New function for determining the tagged type
28430 associated with a tagged primitive subprogram.
28431 (Expand_Dispatching_Call): Add support for a controlling actual that is

28434 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
28435 describing the new layout.
28436 (Dispatch_Table): The expander computes the actual array size, allocates
28437 the Dispatch_Table record accordingly, and generates code that displaces
28438 the base of the record after the Typeinfo_Ptr component. The access to
28439 these components is done by means of local functions.
28440 (Offset_To_Top): New function.
28441 (Typeinfo_Ptr): New function.
28442 (Get_TSD): Modified to access the new position of the TSD.
28443 (Set_TSD): Modified to save the TSD in its new position.

28453 N_Formal_Subtype_Declaration (which is now a subtype).
28454 (Analyze_Formal_Subprogram): Add handling for
28455 N_Formal_Abstract_Subprogram, marking the formal as abstract and
28456 dispatching, setting the controlling status of the formal parameters
28457 and result, and issuing an error if there is no controlling type for
28458 the formal subprogram.
28459 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28460 which is an unclean use of that field, we set the new field
28461 Corresponding_Formal_Spec to make the formal subprogram available to

28463 (Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
28464 Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type

28469 abstract formal subprograms in error check for functions returning
28470 abstract types. Set scope of new designator for

28472 body for nested subprograms, before full analysis of said body.
28473 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
28474 subprogram only if inner one comes from source.
28475 (Analyze_Function_Call): If the call is given in object notation, the
28476 analysis of the name rewrites the node and analyzes it with the proper
28477 argument list. After analyzing the name, if the call has been rewritten
28478 and the result type is set, no further analysis is needed.
28479 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28480 mark in function specification, in a context where the formals are
28481 visible and hide outer homographs.
28483 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28484 as the tagged type for the cases of abstract formal subprograms and
28485 renamings of those. Clean up spec comments.
28486 (Check_Dispatching_Context): Add error message to indicate "abstract
28487 procedure", covering the case of a call to a formal abstract procedure
28488 that has statically tagged operands.
28489 (Check_Dispatching_Call): Check for the case of an actual given by
28490 a tag-indeterminate function call whose type is an ancestor of the
28491 containing call's associated tagged type. This situation can occur
28492 for inherited primitives with function defaults. In this case we
28493 use the tagged type's tag directly as the controlling argument for
28495 (Expand_Call): Name change on call to Expand_Dispatch_Call.
28497 * sprint.adb (Sprint_Node_Actual): Split
28498 N_Formal_Subprogram_Declaration into two alternatives for the new

28574 (gnat_to_gnu_field): Do not necessarily invoke make_packable_type
28575 on the field if Pragma Component_Alignment (Storage_Unit).
28576 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
28577 side-effects as if it were a constant; also make SAVE_EXPR to protect

28595 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28597 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
28598 component of an array of arrays in an assignment context, and the
28599 aggregate has component associations that require sliding on
28600 assignment, force reanalysis of the aggregate to generate a temporary
28601 before the assignment.
28602 (Must_Slide): Make global to the package, for use in Gen_Assign.
28604 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28606 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
28607 unchecked union with no inferable discriminants, return a
28608 Raise_Program_Error node, rather than inserting it at the point the
28610 (Expand_Record_Equality, Component_Equality): Handle properly the case
28611 where some subcomponent is an unchecked union whose generated equality
28612 code raises program error.

28620 Arnaud Charlet <charlet@adacore.com>
28622 * init.c (__gnat_initialize): Add a new parameter eh which contains the
28623 address of the exception registration. The Win32 version of this
28624 routine calls __gnat_install_SEH_handler() to initialize the SEH
28625 (Structured Exception Handling) handler.
28626 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
28627 SEH (Structured Exception Handling) now.
28628 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
28629 (__gnat_initialize for ppc-vxworks): Adjust comments and the
28630 preprocessor condition protecting the call to the extra eh setup
28631 subprogram, which is only available for the ppc target.

28645 Update copyright notice.
28647 * s-tassta.adb (Task_Wrapper): Declare the exception registration

28677 2005-02-09 Vincent Celier <celier@adacore.com>
28679 * prj-makr.adb (Process_Directory): Put file name in canonical case
28680 before matching against the patterns.
28681 If gnatname has been invoked as <prefix>-gnatname
28682 then invoke the compiler as <prefix>-gcc, not just "gcc".
28684 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28686 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28687 with expansion disabled. The actual subtype is needed among other
28688 places when the selected component appears in the context of a loop
28689 bound, and denotes a packed array.
28690 (Operator_Check): Always use the first subtype in the
28691 error message, to avoid the appearance of internal base types.
28692 (Transform_Object_Operation): Copy each actual in full
28693 to the parameter associations of the constructed call, rather than
28694 using the shallow copy mechanism of New_Copy_List. This ensures that
28695 the chaining of named associations is done properly.
28696 (Complete_Object_Operation): Rewrite node, rather than
28697 replacing it, so that we can trace back to the original selected
28700 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28701 and calls that use object notation, if the called function is not
28702 declared in a withed unit, place the elaboration constraint on the
28703 unit in the context that makes the function accessible.
28704 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28705 imposes an elaboration constraint between two packages.
28707 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28709 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28710 views of a private type after handling its private dependents, to
28711 maintain proper stack discipline between entry and exit from the

28727 recursion warnings when compiled with -gnatdm.
28729 2005-02-09 Robert Dewar <dewar@adacore.com>
28731 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
28732 Slight fix to documentation of -gnaty with no parameters
28734 * xr_tabls.ads: Add ??? comment for missing overall comment
28736 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28737 we now use by default.
28739 * xsnames.adb: Adjust end of file test to look for five space followed
28740 by '#' instead of six spaces. The format of xsnames.adb was modified
28741 in the last update.
28743 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28746 * clean.adb: Minor reformatting.
28748 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28749 gnatname.adb: Minor reformatting
28750 Add 2005 to copyright output when utility is run
28752 * csets.adb: Eliminate obsolete comment
28754 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28757 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28759 2005-02-09 Sergey Rybin <rybin@adacore.com>
28761 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28762 the difference between compact and incompact layout and add the record
28763 representation clause to the example illustrating different layouts.
28764 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28765 component clauses").
28767 2005-02-09 Florian Villoing <villoing@adacore.com>
28769 * gnat_ugn.texi: Fix typos.
28770 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or
28772 Make proper use of @ref, @xref and @pxref to avoid duplication of "see"
28773 in the generated documentation.
28775 2005-02-09 Arnaud Charlet <charlet@adacore.com>

29072 is to check if two function signatures for a call-site and a callee are
29073 compatible enough for the call to be valid. The underlying purpose is
29074 to check if a call to a mapped builtin is using the right interface.
29075 The current code actually does not check antyhing - this a placeholder

29127 structure of GARLIC and PolyORB RPC receivers.
29128 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
29130 Simplify elaboration code for RCI packages.
29132 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

29242 note that it applies to obsolete GNAT features, which was previously
29243 omitted. Second we contrast the behavior with that of the new
29244 Ada 2005 AI-368 restriction No_Obsolescent_Features.
29245 Preliminary rewriting of GNAT & libraries chapter in order to take
29246 into account default project locations & new project manager

29477 "no bitfield creation", to be used by make_aligning_type. Don't
29478 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
29479 fields claimed addressable still have to be bitfields. Use
29480 value_factor_p instead of a raw binop construction to check for the
29481 position's alignment.
29483 2004-12-07 Geert Bosch <bosch@adacore.com>

29488 Ed Schonberg <schonberg@adacore.com>
29490 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
29491 with an implicit dereference as its prefix, use
29492 Insert_Explicit_Dereference instead of merely rewriting the prefix into

29494 prefix is generated, if appropriate.
29496 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
29497 dereference is rewritten to an explicit one, generate a reference to
29498 the entity denoted by its prefix using the original prefix node, so

29500 access value, if appropriate.
29502 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
29503 emitting 'assigned but never read' warning on a variable on the basis

29517 an external name, to be handled by the back end.
29519 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
29520 subprogram which is Imported with convention Intrinsic if an
29521 External_Name argument is specified.
29522 (Process_Import_Or_Interface): Properly diagnose link name argument.
29523 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion

29548 PolyORB_Support.Build_Stub_Type): New subrograms containing the
29549 PCS-specific part of Add_Stub_Type.
29550 (Insert_Partition_Check): Use runtime library function to perform

29579 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
29580 and the Has_Pragma_Unreferenced flag for each formal before analyzing
29581 the body, to ensure that warnings are properly emitted for each accept
29582 statement of a given task entry.

29604 (Remove_Next_Debug): Same fix
29606 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
29607 maintain back pointers now, though we did not used to, and comments
29609 (Prepend): Remove pragma Inline.
29610 (Remove_Next): Same cleanup
29612 2004-12-07 Thomas Quinot <quinot@adacore.com>
29614 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
29615 used to record an implicit dereference as a read operation on its
29616 prefix when operating under -gnatc. Necessary to avoid spurious
29617 'variable assigned but never read' warnings in that mode.
29618 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29619 is a non-overloaded implicit dereference, call the above subprogram to
29620 ensure proper recording of references.
29622 2004-12-07 Gary Dismukes <dismukes@adacore.com>
29624 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
29625 to be resolved later as part of Analyze_Iteration_Scheme's call to

29672 2004-12-07 Vincent Celier <celier@adacore.com>
29674 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29675 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29676 and -eit to -ept. Added qualifier
29677 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29679 2004-11-27 Andreas Schwab <schwab@suse.de>
29681 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29683 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29685 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29686 internal implementation unit GNAT.Sockets.Thin,
29687 as their usage for sockets is non-portable (using the read and write
29688 functions from the system runtime library is fine on UNIX but won't
29689 work under Windows).

29693 2004-11-25 Arnaud Charlet <charlet@adacore.com>

29742 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29744 * gigi.h (others_decl, all_others_decl): New decls representing the
29745 new Others_Value and All_Others_Value objects.
29746 (struct attrib): Rename "arg" component as "args", since GCC expects a
29747 list of arguments in there.
29749 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29750 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29753 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29754 others_decl and all_others_decl instead of hardcoded dummy addresses
29755 to represent "others" and "all others" choices, which is cleaner and
29756 more flexible with respect to the possible eh pointer encoding policies.
29758 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29759 (process_attributes): Account for the naming change of the "args"
29760 attribute list entry component.
29762 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29763 cumulating attributes for different entities into a single list.
29764 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29765 attributes for the current entity and propagate first subtype
29766 attributes to other subtypes.
29767 <E_Procedure>: Attribute arguments are attr->args and not
29768 attr->arg any more.
29769 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29770 argument provided, as this is what GCC expects. Use NULL_TREE instead
29773 2004-11-18 Robert Dewar <dewar@adacore.com>
29775 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29776 Minor reformatting througout (including new function specs)
29777 Add ??? comments asking for clarification.
29779 2004-11-18 Thomas Quinot <quinot@adacore.com>
29781 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29782 incomplete duplicate implementation of this subprogram from butil.
29784 2004-11-18 Thomas Quinot <quinot@adacore.com>
29786 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29787 procedures factors the common processing for building an RPC receiver
29788 for an RCI package or an RACW type.
29789 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29790 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29791 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29793 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29795 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29797 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29798 distribution subprogram identifiers that are either subprogram numbers
29800 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29801 string distribution identifiers assigned to a given subprogram.
29802 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29803 (Add_RAS_Dereference_TSS): Add comments.
29804 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29805 is not referenced yet because it will be used by the PolyORB DSA
29807 (Insert_Partition_Check): Remove fossile code.
29808 (First_RCI_Subprogram_Id): Document this constant.
29809 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29811 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29812 replaced with calls to Get_Library_Unit_Name_String. Previously there
29813 were several instances of the same code in different locations in the
29814 compiler; this checkin completes the replacement of all of these
29815 instances with calls to a common subprogram.
29816 Minor reformatting.
29818 * sem_dist.adb: Remove comment noting that RPC receiver generation
29819 should be disabled for RACWs that implement RASs.
29820 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29822 * sem_util.ads, sem_util.adb (Has_Stream): New function
29823 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29824 qualified name of a library unit into the name buffer.
29825 (Note_Possible_Modification): Generate a reference only
29826 if the context comes from source.
29828 * snames.ads (PCS_Names): New subtype corresponding to names of
29829 supported implementations of the Partition Communication Subsystem
29830 (PCS) (i.e. the runtime library support modules for the distributed
29833 2004-11-18 Robert Dewar <dewar@adacore.com>
29834 Ed Schonberg <schonberg@adacore.com>
29836 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
29837 (Has_Rep_Pragma): New function
29838 (Has_Attribute_Definition_Clause): New function
29839 (Record_Rep_Pragma): Moved here from sem_ch13.adb
29840 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29842 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29844 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29845 (Expand_Pragma_Psect_Object): New procedure
29846 These procedures contain the revised and cleaned up processing for
29847 these two pragmas. This processing was formerly in Sem_Prag, but
29848 is more appropriately moved here. The cleanup involves making sure
29849 that the pragmas are properly attached to the tree, and that no
29850 nodes are improperly shared.
29852 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29853 pragmas to Exp_Prag, which is more appropriate.
29854 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29855 check for duplicates Remove use of Is_Psected flag, no longer needed.
29856 Use new Make_String_Literal function with string.
29858 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
29859 that are functions return universal values, that have to be converted
29860 to the context type.
29861 Use new Make_String_Literal function with string.
29862 (Get_Stream_Convert_Pragma): New function, replaces the use of
29863 Get_Rep_Pragma, which had to be kludged to work in this case.
29865 * freeze.adb: Use new Has_Rep_Pragma function
29867 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
29868 function with string.
29869 Use new Has_Rep_Pragma function.
29871 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
29874 2004-11-18 Robert Dewar <dewar@adacore.com>
29876 * errout.ads, errout.adb: (First_Sloc): New function
29878 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
29879 check (-gnatyx) instead of being included as a redundant construct
29882 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
29883 Style_Check_Order_Subprograms.
29885 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
29886 stylesw.adb: Add Style_Check_Xtra_Parens
29888 * usage.adb: Add line for -gnatyx (check extra parens)
29890 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
29892 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29893 Robert Dewar <dewar@adacore.com>
29895 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
29896 discriminant of a constrained subtype, analyze the copy of the
29897 corresponding constraint, because in some cases it may be only
29898 partially analyzed.
29899 Removes long-lived ??? comments.
29901 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
29902 handled controlled or secondary-stack expressions within the
29903 iteration_scheme of a loop.
29905 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
29906 bounds that may contain functions calls, to prevent memory leaks when
29907 the bound contains a call to a function that uses the secondary stack.
29908 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
29909 generate temporaries for loop bounds that might contain function calls
29910 that require secondary stack and/or finalization actions.
29912 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
29913 selected component and the selector is overloadable (not just a
29914 function) treat as function call, Analyze_Call will disambiguate if
29916 (Analyze_Selected_Component): Do not generate an actual subtype for the
29917 selected component if expansion is disabled. The actual subtype is only
29918 needed for constraint checks.
29919 (Analyze_Allocator): If restriction No_Streams is set, then do
29920 not permit objects to be declared of a stream type, or of a
29921 composite type containing a stream.
29923 * restrict.ads: Remove the a-stream entry from Unit_Array, since
29924 No_Streams no longer prohibits with'ing this package.
29926 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
29927 discriminants, but the parent base has unknown discriminants, there is
29928 no discriminant constraint to inherit. Such a discrepancy can arise
29929 when the actual for a formal type with unknown discriminants is a
29930 similar private type whose full view has discriminants.
29931 (Analyze_Object_Declaration): If restriction No_Streams is set, then
29932 do not permit objects to be declared of a stream type, or of a
29933 composite type containing a stream.
29935 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29937 * exp_dbug.ads: Update documentation to reflect simpler encoding for
29938 protected operations.
29940 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
29941 generated name, it complicates decoding in gdb and hinders debugging
29942 of protected operations.
29943 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
29944 flag for the protected entry barrier function.
29945 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
29946 flag for the protected entry function.
29948 2004-11-18 Nicolas Setton <setton@adacore.com>
29950 * expect.c: Define __unix__ when __APPLE__ is defined.
29952 * Makefile.in: Inform the value of the variable GMEM_LIB in the
29953 Darwin-specific section.
29955 * lang-specs.h: Change the placement of the %1 marker.
29956 Works around the fact that gcc adds -fPIC by default under Darwin.
29958 2004-11-18 Ed Schonberg <schonberg@adacore.com>
29960 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
29961 type of the object with the packed array type, set the Analyzed flag
29962 on the object if it is an entity or simple indexed component, to avoid
29963 spurious type errors.
29965 2004-11-18 Gary Dismukes <dismukes@adacore.com>
29967 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
29968 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
29969 separate line from the version message.
29971 2004-11-18 Ed Falis <falis@adacore.com>
29973 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
29975 (init_float): Eliminate initialization of floating point status for
29976 AE653. The instructions have no effect for vThreads.
29978 2004-11-18 Vincent Celier <celier@adacore.com>
29980 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29981 gnatbind is invoked with -shared.
29983 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29985 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29986 for Detect_Blocking which is redundant with the check done within the
29987 procedure Protected_Single_Entry_Call.
29988 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29989 Detect_Blocking which is redundant with the check done within the
29990 procedure Protected_Single_Entry_Call.
29992 2004-11-18 Vincent Celier <celier@adacore.com>
29994 * makegpr.adb (Compile): Put the compiling switches (in package
29995 Compiler and on the command line) immediately after "-c", instead of
29996 at the end of the command line invocation of the compiler, when
29997 compiling a non-Ada file.
29998 (Build_Global_Archive): When there is no need to rebuild the archive,
29999 set Global_Archive_Exists, so that the archive is passed to the linker
30002 2004-11-18 Robert Dewar <dewar@adacore.com>
30003 Sergey Rybin <rybin@adacore.com>
30006 Remove extra paren check from list of checks for redundant constructs
30007 Add documentation of new -gnatyx style check (check extra parens)
30008 Remove paragraph about gnatelim debug options.
30010 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30011 objects rather than forbidding dependencies on the package Ada.Streams.
30013 * sinfo.ads: Add ??? note that we should document pragmas passed to
30016 * g-expect.ads: Fix a few typos in the comments.
30018 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30020 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30023 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30025 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30027 2004-11-07 Andreas Schwab <schwab@suse.de>
30029 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30031 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30034 * Makefile.in (darwin): Set soext to .dylib.
30036 2004-10-26 Vincent Celier <celier@gnat.com>
30037 Thomas Quinot <quinot@act-europe.fr>
30039 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30040 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30041 there is no use of GNAT.Sockets.Constants.
30042 Remove remaining pragma Import for C_Write
30043 Remove C_Read and C_Write from internal implementation unit
30044 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30045 the read and write functions from the system runtime library is fine
30046 on UNIX but won't work under Windows).
30048 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30049 (Check_Selector): Use C_Recv instead of C_Read.
30050 Selectors are the GNAT.Sockets abstraction to perform a select()
30051 call on a set of descriptors. To allow abortion of an ongoing
30052 select operation, some data is written to a dedicated socket that
30053 is always monitored.
30054 Under Windows, the write and read library functions cannot operate
30055 on sockets, so we need to use send and recv instead, which is portable
30056 across all supported platforms.
30058 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30059 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30060 (using the read and write functions from the system runtime library is
30061 fine on UNIX but won't work under Windows).
30063 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30065 * mlib-tgt-darwin.adb: New file.
30067 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30068 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30069 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30070 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30073 * Makefile.in: Add support for building shared libraries under Darwin.
30074 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30075 the low level EH init subprogram to be called from __gnat_initialize.
30077 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30078 indicates which options to pass to the archive indexer.
30080 * mlib-utl.adb: Add support for calling ranlib with additional
30081 options. This is needed for instance under Mac OS X.
30082 (Ranlib_Options): New global variable, used to store the potential
30083 options to pass to ranlib.
30084 (Ar): Use Ranlib_Options when spawning ranlib.
30085 (Initialize): Set the value of ranlib option.
30087 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30089 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30090 instead of 8K, to reflect the real potential needs for stack-checking
30093 2004-10-26 Pascal Obry <obry@gnat.com>
30095 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30097 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30098 Windows only the initial thread stack size can be set so it is good to
30099 start we a low stack size.
30100 The OS will adjust the size as needed.
30102 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30103 Nicolas Setton <setton@act-europe.fr>
30105 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30106 "__unix__" instead of "unix".
30107 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30108 sections were just mistakenly ignored. The former is
30109 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30110 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30111 of hpux. This prevents an unwanted definition of the symbol
30112 convert_addresses in adaint.o.
30114 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30116 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30117 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30119 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30121 * a-filico.ads, a-filico.adb: fix incorrect header.
30123 2004-10-26 Javier Miranda <miranda@gnat.com>
30125 * a-ststio.ads: Fix typo in identifier
30127 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30129 * sem_ch4.adb: Minor reformatting.
30131 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30133 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30134 enabled, check the result of unary and binary operations when the
30135 expression is the right-hand side of an assignment.
30137 2004-10-26 Vincent Celier <celier@gnat.com>
30139 * clean.adb (Delete): Do not output warnings when in quiet output and
30140 not in verbose mode.
30141 (Force_Deletions): New Boolean flag, defaulted to False
30142 (Delete): Only delete a file if it is writable, and when
30143 Force_Deletions is True.
30144 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30145 (Usage): Line for new switch -f
30146 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30149 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30151 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30152 JM type only if its size matches that of the wrapper. When a size is
30153 prescribed and the field is not aliased, remove the wrapper of a JM
30154 type only if the size is not greater than that of the packed array.
30155 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30158 2004-10-26 Geert Bosch <bosch@gnat.com>
30160 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30161 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30162 (Pred): Implement in terms of Succ.
30164 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30166 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30167 unchecked conversion is safe for in-place use if the expression of the
30168 conversion is safe.
30169 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30170 be expandable in place even if the aggregate does not come from source.
30171 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30172 designated object of an allocator in place, rather than building it
30173 first on the stack. The previous scheme forces a full copy of the array,
30174 and may be altogether unsusable if the size of the array is too large
30175 for stack allocation.
30177 2004-10-26 Robert Dewar <dewar@gnat.com>
30179 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30180 compares if the component is atomic.
30182 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30183 array assignment if the component type is atomic.
30185 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30186 Eric Botcazou <ebotcazou@act-europe.fr>
30188 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30189 is aliased and is a by_reference type, do not pass by copy.
30190 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30191 detect whether the call is in the right side of an assignment or
30192 the expression of an object declaration. Recurse on component
30193 association within aggregates.
30194 Call it in the condition that determines whether the temporary is
30195 necessary for correct stack-checking.
30197 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30199 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30200 RACW_Type, used in the PolyORB version.
30201 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30202 version and the GARLIC version.
30204 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30205 Rename RCI_Info to RCI_Locator for better consistency between the
30206 GARLIC and PolyORB versions of the distributed systems annex.
30207 (DSA_Implementation_Name): This enumeration lists the possible
30208 implementations of the Partition Communication Subsystem for the
30209 Distributed Systems Annex (DSA). The three available implementations
30210 are the dummy stub implementation (No_DSA), and two versions based on
30211 two different distribution runtime libraries: GARLIC and PolyORB. Both
30212 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30214 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30217 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30218 between the GARLIC and PolyORB versions of the distributed systems
30220 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30222 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30224 * gnat1drv.adb: Suppress calling the back end when
30225 Frontend_Layout_On_Target is true.
30227 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30229 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30230 Set_Read_Only): New subprograms.
30231 These new routines allow the user to set or unset the Owner execute
30232 and Owner write permission flags on a file.
30234 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30235 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30237 2004-10-26 Matthew Gingell <gingell@gnat.com>
30239 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30241 2004-10-26 Pascal Obry <obry@gnat.com>
30243 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30244 memory before the faulting page we properly test the process read
30245 access for this address using appropriate Win32 routine.
30246 (HPUX sections): guard with "__hpux__" instead of "hpux".
30248 2004-10-26 Robert Dewar <dewar@gnat.com>
30250 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30251 entry parameter if pragma Unreferenced set, since we do not properly
30252 handle the case of multiple parameters.
30254 2004-10-26 Vincent Celier <celier@gnat.com>
30256 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30257 (Ada_Objects_Path.Add): For a library project, add to the object path
30258 the library directory only if there is no object directory or if the
30259 library directory contains ALI files.
30260 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30262 2004-10-26 Vincent Celier <celier@gnat.com>
30264 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30265 extension of library projects.
30267 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30268 path defaults to ".:<prefix>/lib/gnat".
30269 (Parse): For an extending all project, allow direct import of a project
30270 that is virtually extended.
30272 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30273 the specified name is directly imported, return its ID. Otherwise, if
30274 an extension of this project is imported, return the ID of the
30277 2004-10-26 Robert Dewar <dewar@gnat.com>
30279 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30280 (Sub3): New procedure, used by Scaled_Divide
30281 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30282 correct more than one instance of failure to propagate carries
30284 (Double_Divide): Handle overflow case of largest negative number
30285 divided by minus one.
30287 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30288 the case of a quotient value out of range.
30291 2004-10-26 Robert Dewar <dewar@gnat.com>
30293 * s-bitops.adb (Bit_Eq): Remove redundant check.
30295 * s-bitops.ads: Minor comment updates
30296 Change some occurrences of Address to System.Address
30298 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30300 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30302 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30303 accessibility check to prefix that is a protected operation.
30305 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30307 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30308 empty, post message on stub.
30310 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30311 Javier Miranda <miranda@gnat.com>
30313 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30314 current instance appears within a unit that is directly in the context
30316 Used to determine whether the body of the instance should be analyzed
30317 immediately after its spec, to make its subprogram bodies available
30318 for front-end inlining.
30319 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30320 constraint is not allowed on the component type (AARM 12.5.3(3))
30322 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30324 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30325 'Storage_Pool): enhance, document & limit detection of non-sharable
30328 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30330 * s-pooglo.ads: Add more documentation now that this pool is properly
30333 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30335 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30336 or protected type with discriminants, do not constrain the
30337 corresponding record type if the subtype declaration has no
30338 discriminant constraints. This can be the case in source code, or in
30339 the subtype declaration created to rename an actual type within an
30342 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30344 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30345 different kind of stub (possibly wrong name for file), do not check
30347 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30348 includes call to some function that returns an unconstrained type, do
30351 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30353 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30354 appear in the code for the main unit. Dependencies among units in the
30355 context of the main unit are established when those other units are
30356 compiled. Otherwise spurious elaboration constraints can generate
30357 incorrect elaboration circularities.
30359 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30360 Ed Schonberg <schonberg@gnat.com>
30362 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30363 subprogram is called with a parameter that is not an object name. This
30364 situation arises for some cases of illegal code, which is diagnosed
30365 later, and in this case it is wrong to call Is_Aliased, as that might
30366 cause a compiler crash.
30367 (Explain_Limited_Type): Refine previous fix to include
30368 inherited components of derived types, to provide complete information.
30370 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30371 is the prival for a protected object.
30372 It is necessary to mark this entity as a variable, in addition to
30373 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30374 modified to avoid checking the Aliased flag on entities that are not
30375 objects. (Checking that flag for non-objects is erroneous and could
30376 lead to a compiler crash).
30378 2004-10-26 Robert Dewar <dewar@gnat.com>
30380 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30381 X_Frac = 0.5, then we know that the number X must be positive.
30382 (Succ): Remove the same redundant test, and also fix the primary test
30383 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30385 (Decompose): Add fuller comments to spec
30387 2004-10-26 Pascal Obry <obry@gnat.com>
30389 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30390 validity (process must have read access). Set to 0 in all other cases.
30391 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30392 violation on Win32.
30393 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30394 segmentation violation.
30396 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30398 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30399 whose type is a constructed subtype of an aliased object with an
30400 unconstrained nominal subtype, convert the actual to the constructed
30401 subtype before taking its address.
30403 2004-10-26 Vincent Celier <celier@gnat.com>
30405 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30406 (Is_Path_Name_Case_Sensitive): New function
30408 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30409 (Base_Name, Simple_Name, Current_Directory, Compose,
30410 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30413 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30414 Vasiliy Fofanov <fofanov@act-europe.fr>
30415 Vincent Celier <celier@gnat.com>
30417 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30418 "memory management issues" section and document some of the useful
30419 memory pools provided as part of the GNAT library.
30420 Remove "virtual" from declaration of A::method2 in
30421 the simple example of Ada/C++ mixed system.
30422 Library Projects may be virtually extended: their virtual extensions
30423 are not Library Projects.
30424 Added section on extending project hierarchies.
30426 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30428 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30430 (__gnat_portable_spawn): Remove const.
30432 * mingw32.h (MAXPATHLEN): Check for previous definition.
30434 2004-10-17 Matthias Klose <doko@debian.org>
30436 * gnatvsn.ads: Set gnat library version to 4.0.
30438 2004-10-05 Vincent Celier <celier@gnat.com>
30440 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30442 2004-10-04 Laurent Guerby <laurent@guerby.net>
30445 * Makefile.in: Define and use RANLIB_FLAGS.
30447 2004-10-04 Pascal Obry <obry@gnat.com>
30449 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30450 other x86 platforms).
30452 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30454 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30455 in general and triggers stack alignment adjustment for thread entry
30456 points on targets where this is necessary.
30458 2004-10-04 Bernard Banner <banner@gnat.com>
30461 * Makefile.in: Add section for powerpc linux
30462 Add variant i-vxwork-x86.ads
30464 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30466 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30468 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30469 table registration calls when need be. Ensures no reference to the crt
30470 ctors symbol are issued in the SJLJ case, which avoids possible
30471 undefined symbol errors in the case of modules to be statically linked
30474 2004-10-04 Javier Miranda <miranda@gnat.com>
30476 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30477 in-line the code corresponding to subprogram Analyze_Actuals. In
30478 addition, analyze the actuals only in case of subprogram call.
30480 2004-10-04 Ed Falis <falis@gnat.com>
30482 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30484 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30486 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30487 in the documentation.
30489 2004-10-04 Robert Dewar <dewar@gnat.com>
30491 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30493 (Analyze_Block_Statement): Add circuitry to detect following dead code
30494 (Check_Unreachable_Code): Handle case of block exit
30496 2004-10-04 Robert Dewar <dewar@gnat.com>
30498 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30499 (XMatchD): Avoid warning for Logic_Error call
30501 2004-10-04 Robert Dewar <dewar@gnat.com>
30503 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30504 consider expressions buried within a procedure actual to be an actual.
30505 This caused some blowups with uses of packed slices within a procedure
30508 2004-10-04 Robert Dewar <dewar@gnat.com>
30510 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30511 longer need to be initialized to zero.
30512 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30513 initialized to zero.
30515 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30516 considered valid, even if the representation is modular. That's correct
30517 now that we no longer initialize packed modular arrays to zero.
30519 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30520 suffixes. These are now documented as the only cases in which the
30521 debugger ignores outer records.
30522 Previously, the spec allowed arbitrary suffixes for this purpose.
30523 Change name of LJM to JM for packed array pad records
30524 Create separate section on packed array handling, and add a whole new
30525 set of comments to this section describing the situation with packed
30526 modular types and justification requirements depending on endianness.
30528 2004-10-04 Robert Dewar <dewar@gnat.com>
30530 * a-except.adb: Add a comment for last change
30532 * einfo.ads: Minor spelling correction in comment
30534 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
30536 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
30539 * sem_util.ads: Minor comment update
30541 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30543 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30544 Inline_Always when in Configurable_Run_Time mode.
30546 * sem_prag.adb (Process_Convention): If entity is an inherited
30547 subprogram, apply convention to parent subprogram if in same scope.
30548 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30549 when in Configurable_Run_Time mode.
30551 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30553 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30554 class_wide type after component list has been inherited.
30556 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30558 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30559 Denotes_Previous_Actual, to handle properly the case of a private
30560 actual that is also the component type of a subsequent array actual.
30561 The visibility status of the first actual is not affected when the
30562 second is installed.
30563 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30564 make fully recursive the treatment of formals of packages declared
30566 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30567 the above on exit from an instantiation.
30568 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30569 current instantiation which is now complete.
30570 (Analyze_Package_Instantiation): No instantiated body is needed if the
30571 main unit is generic. Efficient, and avoid anomalies when a instance
30572 appears in a package accessed through rtsfind.
30574 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30576 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30577 do not generate a declaration for a temporary if the call is part of a
30578 library-level instantiation.
30580 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30582 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30583 searching for a limited component to flag.
30585 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30586 expansion of Input, to account for the fact that the implicit call
30587 generated by the attribute reference must freeze the user-defined
30588 stream subprogram. This is only relevant to 'Input, because it can
30589 appear in an object declaration, prior to the body of the subprogram.
30591 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30592 expansion can proceed and further errors uncovered.
30593 (Minor clean up): Fix cases of using | instead of \ for continuation
30596 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
30598 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
30600 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
30601 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.
30602 Use gcc_assert and gcc_unreachable.
30604 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30605 specified alignment before validating size.
30606 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30607 stripped-down declaration for the type of the inner field when making
30610 * utils.c (finish_record_type): Do not compute the size in units
30611 incrementally. Instead compute it once for the rep clause case.
30612 Use gcc_assert and gcc_unreachable.
30614 2004-10-04 Vincent Celier <celier@gnat.com>
30616 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30618 (Is_Valid_Path_Name): Take '/' as a directory separator.
30620 2004-10-04 Vincent Celier <celier@gnat.com>
30622 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30623 (Extended_Project) only if Extended_Project is defined, to avoid
30625 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30627 (Parse_Single_Project): Ditto.
30629 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30630 Add_To_Project_Path for virtual projects.
30632 2004-10-04 Vincent Celier <celier@gnat.com>
30634 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30635 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30636 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30637 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30638 parameter Options_2.
30640 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30641 Build_Dynamic_Library with an empty Options_2.
30643 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30646 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30647 directory separator, if any.
30648 (Gprmake): Do not allow mains on the command line for library projects.
30649 Do not attempt to link when the project is a library project.
30650 (Library_Opts): New table to store Library_Options.
30651 (Build_Library): If Library_Options is specified, pass these options
30652 when building a shared library.
30654 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30656 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30657 the end of this procedure now that the unlock operation was inserted
30660 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30662 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30663 corresponding to the Preallocated_Stacks flags in System.
30664 (Get_Target_Parameters): Including the processing for
30665 Preallocated_Stacks.
30667 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,
30668 system-vms_64.ads, system-unixware.ads, system-linux-ia64.ads,

30676 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30677 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30678 used to signal whether the compiler creates the required stacks and
30679 descriptors for the different tasks (when True) or it is done by the
30680 underlying operating system at run time (when False).
30681 It is initially set to False in all targets.
30683 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30684 if it is supported by the target.
30685 (Make_Task_Create_Call): Pass the stack address if it has been
30686 previously created. Otherwise pass a Null_Address.
30688 * snames.adb: Add _stack.
30690 * snames.ads: Add Name_uStack. Required to allow the expander to
30691 statically allocated task stacks.
30693 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30694 Stack_Address argument.
30695 Check that its value is equal to Null_Address because this target does
30696 not support the static stack allocation.
30698 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30700 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30703 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30705 * exp_dist.adb: Split declaration of asynchronous flag out of
30706 Add_RACW_Read_Attribute.
30707 Minor reformatting for better alignment with PolyORB version.
30708 Store the entity for the asynchronous flag of an RACW, rather than the
30709 expression, in the asynchronous flags table. This will allow this flag
30710 to be used in other subprograms beside Add_RACW_Read_Attribute.
30712 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30714 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30718 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30719 sockets constant MSG_NOSIGNAL (Linux-specific).
30720 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30721 all Send operations.
30722 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30723 from trigerring SIGPIPE.
30724 Rename components to avoid clash with Ada 2005 possible reserved
30726 (Check_Selector): When the select system call returns with an error
30727 condition, propagate Socket_Error to the caller.
30729 2004-10-01 Jan Hubicka <jh@suse.cz>
30731 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
30733 2004-09-23 Robert Dewar <dewar@gnat.com>
30736 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
30737 instead do this at freeze time (we won't do it if there is an address
30739 Change "pragma inline" to "pragma Inline" in information and error
30741 Minor reformatting.
30743 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30744 right way of doing things after all.
30745 (Freeze_Entity): For object, set Is_Public for imported entities
30746 unless there is an address clause present.
30748 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30750 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30751 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30752 ensures proper handling of types with rep clauses, which might have
30753 their TYPE_SIZE set already.
30755 2004-09-21 Robert Dewar <dewar@gnat.com>
30757 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30758 packed array types in both little- and big-endian cases. This change
30759 ensures that we no longer count on the unused bits being initialized
30760 for such types (and in particular ensures that equality testing will
30761 only read the relevant bits).
30762 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30763 These changes mean that we no longer need to initialize small packed
30765 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30766 optimization to an LJM field as to its parent field.
30768 * ada-tree.h, trans.c, utils.c, utils2.c:
30769 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30771 2004-09-20 Jan Hubicka <jh@suse.cz>
30773 * utils.c (gnat_finalize): Remove.
30774 (end_subprog_body): Directly call cgraph_finalize_function;

30780 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30781 if an address clause is present, since that means that the Import

30813 Convert the result to File_Size.
30815 * prj.ads: (Project_Error): New exception
30817 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30818 Prj.Com, not from Osint.
30819 (Attrs, Package_Attributes): Tables moved to private part of spec
30820 (Add_Attribute, Add_Unknown_Package): Moved to new child package

30825 Fail. Check that package name is not already in use.
30827 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30828 used by tools, not only by the project manager, and to indicate that
30829 exception Prj.Prj_Error may be raised in case of problem.
30830 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30832 (Attrs, Package_Attributes): Table instantiations moved from the body to
30833 the private part to be accessible from Prj.Attr.PM body.
30835 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30836 from new package Prj.Attr.PM.
30837 (Parse_Attribute_Declaration): Call Add_Attribute from new package

30888 pragmas recognized by GNAT.
30890 * gnat_rm.texi: Document pragma Detect_Blocking.
30892 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
30893 raise Program_Error if called from a protected operation.
30895 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
30896 the protected action nesting level.
30897 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
30898 protected action nesting level.
30899 (Unlock): When pragma Detect_Blocking is active decrease the protected
30900 action nesting level.
30902 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
30903 Protected_Action_Nesting.
30905 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
30906 Common_ATCB record. It contains the dynamic level of protected action
30907 nesting for each task. It is needed for checking whether potentially
30908 blocking operations are called from protected operations.
30909 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
30910 Detect_Blocking is active or not in the partition.
30912 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
30913 raise Program_Error if called from a protected operation.

30944 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
30945 insertion of the statement raising Program_Error. The run time
30946 contains the required machinery for handling that.
30948 * sem_util.ads: Change comment associated to procedure
30949 Check_Potentially_Blocking_Operation.
30950 This procedure does not insert a call for raising the exception because
30951 that is currently done by the run time.
30953 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
30955 * init.c: Add the global variable __gl_detect_blocking that indicates
30956 whether pragma Detect_Blocking is active (1) or not (0). Needed for
30957 making the pragma available at run time.
30958 (__gnat_set_globals): Pass and update the detect_blocking parameter.
30960 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
30961 pragma Detect_Blocking is active.
30963 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
30965 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
30966 DB is found in the ali file. Any unit compiled with pragma
30967 Detect_Blocking active forces its effect in the whole partition.
30969 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
30970 Detect_Blocking is active and delay is called from a protected
30973 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
30974 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
30975 Detect_Blocking is active (0 otherwise).
30976 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
30977 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30980 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30982 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30983 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash

30987 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30988 Update API in placeholder implemetation of s-parint to reflect changes
30989 in distribution runtime library.
30991 * sem_ch3.adb (Expand_Derived_Record): Rename to
30992 Expand_Record_Extension.
30994 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30995 primitive operations of potentially distributed object types that have
30996 non-controlling anonymous access formals.
30998 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31000 New implementation of expansion for remote access-to-subprogram types,
31001 based on the RACW infrastructure.
31002 This version of sem_dist is compatible with PolyORB/DSA as well as
31005 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31006 Asynchrronous that applies to a remote access-to-subprogram type, mark
31007 the underlying RACW type as asynchronous.
31009 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31010 __gnat_using_gnu_linker to 1.
31012 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31013 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31014 GNAT.Perfect_Hash_Generators, and remove the empty

31019 * exp_ch3.adb (Expand_Derived_Record): Rename to
31020 Expand_Record_Extension.
31021 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31022 a component declaration must remain attached at that point in the
31023 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31024 It is therefore necessary to take a copy of the expression when building
31025 the corresponding assignment statement in the init proc.
31026 As a side effect, in the case of a derived record type, we now see the
31027 original expression, without any rewriting that could have occurred
31028 during expansion of the ancestor type's init proc, and we do not need
31029 to go back to Original_Node.
31031 * exp_ch3.ads (Expand_Derived_Record): Rename to
31032 Expand_Record_Extension.
31034 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

31037 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31038 New subprograms. Used to create a proxy tagged object for a remote
31039 subprogram. The proxy object is used as the designated object
31040 for RAS values on the same partition (unless All_Calls_Remote applies).
31041 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31042 System.Partition_Interface.Get_Unique_Remote_Pointer.
31043 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31044 Renamed from Add_RAS_*_Attribute.
31045 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31047 New implementation of expansion for remote access-to-subprogram types,
31048 based on the RACW infrastructure.
31050 * exp_dist.ads (Copy_Specification): Update comment to note that this
31051 function can copy the specification from either a subprogram
31052 specification or an access-to-subprogram type definition.
31054 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31056 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31057 in an instance, between an explicit subprogram an one inherited from a
31058 type derived from an actual.
31060 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31061 add a polling call if the subprogram is to be inlined by the back-end,
31062 to avoid repeated calls with multiple inlinings.
31064 * checks.adb (Apply_Alignment_Check): If the expression in the address
31065 clause is a call whose name is not a static entity (e.g. a dispatching
31066 call), treat as dynamic.

31070 * g-trasym.ads: Minor reformatting
31072 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31078 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
31081 2004-09-09 Pascal Obry <obry@gnat.com>
31083 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31084 enable map file generation. Add the right option to generate the map
31085 file if Map_File is set to True.
31087 * gnatdll.adb (Gen_Map_File): New variable.
31088 (Syntax): Add info about new -m (Map_File) option.
31089 (Parse_Command_Line): Add support for -m option.

31114 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
31116 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31117 of variable length temporaries for function return now that the
31118 back-end and gigi support it.

31175 * gnat-style.texi: Minor updates (note that boolean constants and
31176 variables are joined with AND/OR rather than short circuit forms).
31178 2004-09-01 Ed Schonberg <schonberg@gnat.com>
31180 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if
31181 it is an upward conversion of an untagged type with no representation

31193 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
31194 pragma Debug as an if statement with a constant condition, for
31195 consistent treatment of entity references contained within the
31196 enclosed procedure call.
31198 2004-09-01 Vincent Celier <celier@gnat.com>
31200 * bindgen.adb: (Set_EA_Last): New procedure
31201 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
31203 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing

31225 2004-09-01 Pascal Obry <obry@gnat.com>
31227 * gprcmd.adb (Extend): Do not output trailing directory separator. This
31228 is not needed and it confuses Windows GNU/make which does not report
31229 directory terminated by a slash as a directory.
31230 (gprcmd): Idem for "pwd" internal command.
31232 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
31233 target names rewrite to fix regressions with recent version of

31339 unit, this is an attempt to inline a construct that is not available in
31340 the current restricted mode, so abort rather than trying to continue.
31342 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31343 discriminants that rename those of the parent, recover names of
31344 original discriminants for the constraint on the full view of the

31375 returning C.int, to avoid using a derived boolean type.
31377 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

33330 interpretations for rewritten right operand.
33331 (Set_Mixed_Mode_Operand): Handle properly a universal real operand when

33717 * g-os_lib.adb (Normalize_Pathname.Final_Value): Remove trailing
33718 directory separator.
33720 * prj-proc.adb (Recursive_Process): Inherit attribute Languages from
33721 project being extended, if Languages is not declared in extending

33726 * sem_ch10.adb (Install_Limited_Withed_Unit): Do not install the
33727 limited view of a visible sibling.
33729 2004-05-14 Robert Dewar <dewar@gnat.com>
33731 * gnat_ugn.texi: Minor change to -gnatS documentation
33733 * sprint.adb: Remove some instances of Assert (False) and for this
33734 purpose replace them by output of a ??? string.
33736 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
33739 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
33740 flag processing. This was suppressing required dependencies in
33741 No_Run_Time mode and is not needed since the binder does not generate
33742 references for things in libgnat anyway.
33744 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
33747 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
33749 * gnat_ugn.texi: Document AIX-specific issue with initialization of
33752 * exp_ch4.adb (Insert_Dereference_Action): Do not generate dereference
33753 action for the case of an actual parameter in an init proc call.
33755 2004-05-14 Ed Schonberg <schonberg@gnat.com>
33757 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
33758 subtype, check visible entities in base type.
33760 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
33761 actions if the object is a renaming.
33763 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
33764 Check_Formal_Package_Instance, to determine more precisely when the
33765 formal and the actual denote the same entity.
33767 2004-05-14 Javier Miranda <miranda@gnat.com>
33769 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
33771 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
33772 corresponding to a private_with must be removed from visibility; it
33773 will be made visible later, just before we analyze the private part of
33775 (Check_Private_Child_Unit): Allow private_with clauses in public
33777 (Install_Siblings): Make visible the private entities of private-withed
33779 (Install_Withed_Unit): Do not install the private withed unit if we
33780 are compiling a package declaration and the Private_With_OK flag was
33781 not set by the caller. These declarations will be installed later,
33782 just before we analyze the private part of the package.
33784 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
33785 during the evaluation of the expression that initializes the object,
33786 decorate it with the expected type to avoid cascade errors.
33789 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
33790 subprogram we have to install the private_with clauses after its
33791 specification has been analyzed (as documented in AI-262.TXT).
33793 * sem_ch8.adb (Has_Private_With): New function. Determines if the
33794 current compilation unit has a private with on a given entity.
33795 (Find_Direct_Name): Detect the Beaujolais problem described in
33798 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
33799 provides the functionality of the function Is_Ancestor that was
33800 previously available in sem_ch10. It has been renamed to avoid
33803 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
33805 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
33807 * utils.c (build_vms_descriptor): Use SImode pointers.
33809 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>
33811 * gnat_ugn.texi: Revised chapter "GNAT and Libraries".

33963 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
33965 2004-05-13 Diego Novillo <dnovillo@redhat.com>
33967 Merge from tree-ssa-20020619-branch.
33969 * config-lang.in (boot_language, build_by_default): Set
33971 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
33972 (max_size): Add static chain op for call_expr.
33974 2004-05-12 Richard Sandiford <rsandifo@redhat.com>
33977 * 5gmastop.adb (Roff): Choose between '4' and '0', not '4' and ' '.
33979 2004-05-11 Roger Sayle <roger@eyesopen.com>
33981 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
33984 2004-05-10 Doug Rupp <rupp@gnat.com>
33986 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
33989 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
33991 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
33993 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
33994 Fixes undefined symbols in IA64 gnatlib.
33996 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
33998 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
33999 Short_Address). This will be moved to system.auxdec.
34001 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
34003 * sem_util.adb: Replace test for presence of a node that is always
34004 present with a call to Discard_Node.
34006 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
34007 Analyze on the library unit node after generation of distribution stub
34008 constructs. The call was a no-op because Unit_Node has already been
34009 Analyzed, and the tree fragments for the distribution stubs are
34010 analyzed as they are inserted in Exp_Dist.
34011 Update comment regarding to distribution stubs to reflect that we
34012 do not generate stub in separate files anymore.
34014 * einfo.ads: Clarify the fact that a tagged private type has the
34015 E_Record_Type_With_Private Ekind.
34017 * erroutc.adb: Minor reformatting
34019 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
34020 values if line length is increased using -gnatyM (noticed during code
34023 * eval_fat.adb: Minor reformatting
34024 Put spaces around exponentiation operator
34026 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34029 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
34030 has been rewritten as an explicit dereference, retrieve type of
34031 original node to check for possibly unconstrained record type.
34033 2004-05-10 Ed Schonberg <schonberg@gnat.com>
34035 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
34036 overriding, use the operation of the parent unconditionally.
34038 * sem_ch4.adb (Remove_Address_Interpretations): Remove address
34039 operation when either operand is a literal, to avoid further
34042 * sem_ch6.adb (New_Overloaded_Entity): If new entity is inherited and
34043 overridden by a previous explicit declaration, mark the previous entity
34046 * sem_disp.adb (Check_Dispatching_Operation): New predicate
34047 Is_Visibly_Controlled, to determine whether a declaration of a
34048 primitive control operation for a derived type overrides an inherited
34049 one. Add warning if the explicit declaration does not override.
34051 2004-05-10 Vincent Celier <celier@gnat.com>

34588 whether a pragma All_Calls_Remote applies to the subprogram on which
34590 No functional change is introduced by this revision; the new parameter

35181 export only when the export is coming from source. This may be not
35182 be true e.g. on VMS where we expand export pragmas for exception codes

35324 * sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
35325 complete assignment subtree which is now unnecessary, as the expansion
35326 of inlined call has been improved to preserve a consistent assignment
35327 tree. Note_Possible_Modification must be called only
35328 after checks have been applied, or else unnecessary checks will

35650 a classwide type (for which Is_Object_Reference holds), but it can
35651 also be a value conversion for an access-to-classwide type. In the
35652 latter case, there is an implicit dereference, and the original node
35653 for the prefix does not verify Is_Object_Reference.
35655 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35656 conversion of a discriminant-dependent component of a mutable object
35659 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35661 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35662 inherited, has convention C, and has unconstrained array parameters,
35663 place the corresponding warning on the derived type declaration rather
35664 than the original subprogram.
35666 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35667 indication on renaming declaration, if formal has a box and actual
35670 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35671 determine whether to generate an implicit or explicit reference to
35672 the renamed entity.
35674 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35675 subprogram renaming comes from a defaulted formal subprogram in an
35678 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35680 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35681 value expressions to ensure that calls within a component definition
35682 will be checked (since those are evaluated during the record type's
35685 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35687 * s-tpobop.adb: Code clean up:
35688 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35699 of No_Strict_Aliasing to build_pointer_type_for_mode.
35700 * utils.c (update_pointer_to): Walk pointer and ref chains.
35702 2004-03-22 Cyrille Comar <comar@act-europe.fr>

35707 Has_RACW, Is_Generic, etc.)
35708 (Output_Object, Gnatls): Take into account ALI files not attached to
35711 2004-03-22 Vincent Celier <celier@gnat.com>
35713 * gprep.adb: Change all String_Access to Name_Id
35714 (Is_ASCII_Letter): new function
35715 (Double_File_Name_Buffer): New procedure
35716 (Preprocess_Infile_Name): New procedure

35728 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
35729 case when the source contains only comments.
35731 2004-03-22 Ed Schonberg <schonberg@gnat.com>
35733 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35734 declaration for a child subprogram body that acts as a spec, indicate
35735 that the entity in the declaration needs debugging information.
35737 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35738 full view if the subtype is created for a constrained record component;
35739 gigi has enough information to construct the record, and there is no
35740 place in the tree for the declaration.
35742 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35743 serial number for the dummy body that is built for analysis, to avoid
35744 inconsistencies in the generation of internal names when compiling
35747 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
35749 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
35752 2004-03-22 GNAT Script <nobody@gnat.com>

35775 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35776 gnat_ug_wnt.texi: Regenerate.
35778 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35780 * ada-tree.h: Update copyright notice.
35781 Minor reformatting.
35783 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35785 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35786 as regular exception objects and not as mere integers representing the
35787 condition code. The latter approach required some dynamics to mask off
35788 severity bits, which did not fit well into the GCC table based model.
35789 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35790 exception data objects. We don't it and it would conflict with the other
35791 external symbol we have to generate for such exceptions.
35793 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35794 the special code for VMS exceptions, since these are now represented
35795 as regular exceptions objects.
35797 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35799 * decl.c (debug_no_type_hash): Remove.

35803 2004-03-19 Laurent Guerby <laurent@guerby.net>
35805 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35806 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35808 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35810 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35811 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35812 (TYPE_RM_SIZE_INT): Directly use type.values.
35813 (TREE_LOOP_ID): Clean up check.
35814 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35815 TYPE_VALUES, not TYPE_FIELDS.

35826 Specific.Set instead of direct call to e.g pthread_setspecific.
35828 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35830 * adaint.c: Update comments.
35832 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35833 GNATLIB_SHARED for FreeBSD.
35835 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35837 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35838 When needed (stack checking) the stack size is retrieved
35839 from the VxWorks kernel.
35841 * Makefile.in: Flag -nostdinc is required when building the run time
35842 for avoiding looking for files in the base compiler.
35843 Add the VxWorks specific version of the package body for
35844 System.Stack_checking.Operations (5zstchop.adb).
35846 * Make-lang.in: Add the object file for
35847 System.Stack_Checking.Operations.
35849 * Makefile.rtl: Add object file for the package
35850 System.Stack_Checking.Operations.

35854 * s-stache.ads, s-stache.adb: Move the operations related to stack
35855 checking from this package to package System.Stack_Checking.Operations.
35856 This way, stack checking operations are only linked in the final
35857 executable when using the -fstack-check flag.
35859 2004-03-18 Doug Rupp <rupp@gnat.com>
35861 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).

35871 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
35872 the procedures Add_To_Path_File.
35873 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
35874 making sure that each directory is present only once and, for object
35875 dirs, when a directory already present is added, the duplicate is
35876 removed and the directory is always put as the last in the table.
35877 Write the path files at the end of these accumulations.
35879 * prj-nmsc.adb (Record_Source): Add source file name in hash table
35880 Files_Htable for all sources.
35882 * prj-proc.adb (Process): Remove restrictions between not directly
35883 related extending projects.

35891 parameter Trusted_Mode.
35893 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
35895 * scn.adb (Determine_License): Take into account a degenerated case
35896 when the source contains only comments.
35898 2004-03-18 Ed Schonberg <schonberg@gnat.com>
35900 * sem_warn.adb (Check_References): For a warning on a selected
35901 component that does not come from source, locate an uninitialized
35902 component of the record type to produce a more precise error message.
35904 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
35906 * 3zsoccon.ads: Fix multicast options.
35908 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
35911 2004-03-15 Robert Dewar <dewar@gnat.com>
35913 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
35914 pragma used for a private type.
35916 * lib-xref.adb (Generate_Reference): Do not generate warning if
35917 reference is in a different unit from the pragma Unreferenced.
35919 * 5vtpopde.adb: Minor reformatting
35920 Fix casing of To_Task_ID
35922 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
35923 flag if we have an unchecked conversion to an access type in the same
35926 2004-03-15 Geert Bosch <bosch@gnat.com>
35928 * a-ngcoty.adb (Modulus): In alternate formula for large real or
35929 imaginary parts, use Double precision throughout.
35931 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
35932 we want to be able to compile run-time with -gnata for testing, but
35933 this may also be instantiated in user code that is compiled with -gnata.
35935 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
35937 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
35938 codes. Having a separate type for this is useful to enforce consistency
35939 throughout the various run-time units.
35940 (Exception_Data): Use Exception_Code for Import_Code.
35942 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
35943 Natural and Integer in various places.

35945 with the severity bits masked off.
35946 (Register_VMS_Exception): Handle the additional exception data pointer
35949 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
35950 component, now reflected by an exported accessor.
35951 (is_handled_by): New routine to compute whether the propagated
35952 occurrence matches some handler choice specification. Extracted out of
35953 get_action_description_for, and expanded to take care of the VMS
35955 (get_action_description_for): Use is_handled_by instead of an explicit
35956 complex condition to decide if the current choice at hand catches the
35957 propagated occurrence.
35959 * raise.h (Exception_Code): New type for C.
35961 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
35962 System.Standard_Library.Exception_Code, to allow references from the
35963 pragma import/export expander.
35965 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
35966 New accessors to allow easy access to GNAT exception data
35968 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
35969 redundant Handled_By_Others component, helper for the personality
35970 routine which will now be able to call the appropriate exception data
35973 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
35974 component of Standard_Exception_Type to be the closest possible to
35975 Exception_Code in System.Standard_Library, that we cannot get at this
35976 point. Expand a ??? comment to notify that this type node should
35977 probably be rewritten later on.
35979 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35980 registration call to include a pointer to the exception object in the
35983 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35984 instead of int and explicit bitmasks.
35986 2004-03-15 Vincent Celier <celier@gnat.com>
35988 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35989 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35991 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35992 longer needed now that it is in the spec of
35993 System.Tasking.Task_Attributes.
35995 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35997 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35999 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36001 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36002 taken care of in Scan_Make_Arg.
36003 (Scan_Make_Arg): Add the executable suffix only if the argument
36004 following -o, in canonical case, does not end with the executable
36005 suffix. When in verbose mode and executable file name does not end
36006 with executable suffix, output the executable name, in canonical case.
36008 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
36009 to avoid warnings when instantiating Ada.Task_Attributes.
36012 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
36013 in the correct order.
36015 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
36016 redirect standard output and error to a file for the invocation of the
36017 compiler, then read the file.
36019 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
36020 directory, instead of the Value.
36021 (Find_Source_Dirs): Remove useless code & comments.
36023 2004-03-15 Ed Schonberg <schonberg@gnat.com>
36025 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36026 tagged type is inherited, and the parent operation is not frozen yet,
36027 force generation of a freeze node for the inherited operation, so the
36028 corresponding dispatch entry is properly initialized.
36029 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
36030 when looking for user-defined equality operation.
36032 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
36033 boolean when locating primitive equality of tagged component.
36035 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
36036 bit-aligned field and the right-hand side a string literal, introduce
36037 a temporary before expanding assignment into a loop.
36039 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
36040 priority in full, to ensure that any expanded subepxressions of it are
36041 elaborated in the scope of the init_proc.
36043 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
36044 after object declaration, skipping over code that may have been
36045 generated for validity checks.
36047 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
36048 discriminants, ignore the known discriminants of its full view, if
36049 any, to check legality.
36051 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
36052 component if type has unknown discriminants.
36053 (Analyze_Private_Extension_Declaration): Discriminant constraint is
36054 null if type has unknown discriminants.
36056 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
36057 for end label when present.
36059 * s-fileio.adb (Open): When called with a C_Stream, use given name for
36060 temporary file, rather than an empty string.
36062 2004-03-15 Ed Falis <falis@gnat.com>
36064 * s-thread.adb: Removed, no longer used.
36066 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

36086 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
36087 Insert_Dereference_Action when rewriting an implicit dereference into
36088 an explicit one, this will be taken care of during expansion of the
36089 explicit dereference.
36090 (Expand_N_Slice): Same. Always do the rewriting, even for the case
36091 of non-packed slices, since the dereference action generated by
36092 expansion of the explicit dereference is needed in any case.
36093 (Expand_N_Selected_Component): When rewriting an implicit dereference,
36094 analyze and resolve the rewritten explicit dereference so it is seen
36096 (Insert_Dereference_Action): This procedure is now called only for the
36097 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
36098 dereferences that do not come from source (including explicit
36099 dereferences resulting from rewriting implicit ones), but do not
36100 recursively insert a check for the dereference nodes contained within
36102 (Insert_Dereference_Action): Clarify and correct comment.

36979 checks for bitfield creation are triggered.
36980 (finish_record_type): During last pass over the fields, clear
36981 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37323 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
37324 generated to rename a generic actual, go to the actual itself, the

37440 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37441 N_String_Literal node always references an E_String_Literal_Subtype
37442 entity. This may not be true in the future.
37443 (Possible_Bit_Aligned_Component): Move processing of
37444 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37446 * exp_ch6.adb (Expand_Thread_Body): Pick up

37451 (Type_May_Have_Bit_Aligned_Components): New function.

37491 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37492 ineffective elaborate all pragmas on non-visible packages (this
37493 happened when a renamed subprogram was called). Now the elaborate all
37494 always goes on the package containing the renaming rather than the one
37495 containing the renamed subprogram.
37497 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37498 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37523 * make.adb (Gnatmake): Special process for files to compile/check when
37524 -B is specified. Fail when there are only foreign mains in attribute

37559 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37560 all attributes, including read-only attribute.

37565 library naming scheme.

37599 checked when limited aggregates are implemented.

37602 pure, emit warning.

37779 * 7sintman.adb: Minor reformatting
37781 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37782 standard linker options to get standard libraries linked. We now plan
37783 to provide dummy versions of these libraries to match the appropriate
37784 configurable run-time (e.g. if a library is not needed at all, provide
37785 a dummy empty library).
37787 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37788 options (-L parameters and standard libraries). What we plan to do is
37789 to provide dummy libraries where the libraries are not required.
37791 * gnatbind.adb: Minor comment improvement
37793 2003-12-08 Javier Miranda <miranda@gnat.com>
37795 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
37796 aggregate in the parent. Otherwise constants with limited aggregates
37797 are not supported. Add new formal to pass the component type (Ctype).
37798 It is required to call the corresponding IP subprogram in case of
37799 default initialized components.
37800 (Gen_Assign): In case of default-initialized component, generate a
37801 call to the IP subprogram associated with the component.
37802 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
37803 of aggregate with default initialized components.
37804 (Has_Default_Init_Comps): Improve implementation to recursively check

37807 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37808 to indicate that the initialization call corresponds to a
37809 default-initialized component of an aggregate.
37810 In case of default initialized aggregate with tasks this parameter is
37811 used to generate a null string (this is just a workaround that must be
37812 improved later). In case of discriminants, this parameter is used to
37813 generate a selected component node that gives access to the discriminant
37816 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37817 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37818 allocated aggregates with default-initialized components.
37820 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
37821 the box notation is used in positional aggregates.

37863 Process nodes N_Comment.
37865 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
37866 without comments and there are some comments, set the flag
37867 Unkept_Comments to True.
37868 (Scan): If there are comments, set the flag Unkept_Comments to True and
37869 clear the comments.

37909 Correct typo in comment
37910 (Resolve_Aggregate): In case of array aggregates set the estimated
37911 type of the aggregate before calling resolve. This is needed to know
37912 the name of the corresponding IP in case of limited array aggregates.

37934 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
37936 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
37937 they are automatically generated by Make-lang.in and cause nothing but
37938 maintenance troubles.
37940 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
37942 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

37956 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
37957 to ensure that the kernel fills in the interrupted context structure
37958 before calling a signal handler, which is necessary to be able to
37959 unwind past it. Update the copyright notice.
37961 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
37963 * a-elchha.ads: New file.
37965 * a-elchha.adb: New default last chance handler. Contents taken from
37966 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

38048 included in HIE_NONE_TARGET_PAIRS.
38050 2003-12-03 Ed Schonberg <schonberg@gnat.com>
38053 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
38054 is legal in an instance, because legality is cheched in the template.

38075 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
38076 so that the debugger can reliably access the value of the parameter,

38212 Add to Unblocked_Signal_Mask the set of signals that are in
38216 Adding a check to see whether the Interrupt_ID we want to unmask is in
38217 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
38218 reason is that the index type of the Keep_Unmasked array is not always
38219 Interrupt_ID; it may be a subtype of Interrupt_ID.
38221 2003-11-24 Gary Dismukes <dismukes@gnat.com>
38224 (Remove_Side_Effects): Condition constantness of object created for a

41645 function approach did not work well because of a side effect (the
41646 function call could reallocate the table which was being indexed
41647 using its result). Fixes ada/4851.

42017 Fix comment of Shutdown_Socket and Close_Socket. These functions
42018 should not fail silently because if they are called twice, this
42019 probably means that there is a race condition in the user program.
42020 Anyway, this behaviour is consistent with the rest of this unit.
42021 When an error occurs, an exception is raised with the error message
42022 as exception message.

43361 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43362 instead of simple checksum.
43363 (CRC_Match): new function.
43364 (CRC_Error): new constant.
43366 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43367 a CRC now and not a simple checksum. A CRC uses lower-case hex
43368 letters, fixes ambiguity in parsing.
43370 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43371 is what this variable will store.
43373 * bcheck.adb: Change reference to chechsum in comments by CRC.
43374 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43375 rename All_Checksum_Match to All_CRC_Match. Change due to API
43376 renaming since now GNAT does not use a simple checksum but a
43377 CRC using GNAT.CRC32.
43379 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43380 now and not anymore a simple checksum.

43417 Update comments for the CRC.
43419 * types.adb (Hex): Use lowercase for the letter part.
43421 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43422 for a word. This is currently used only for CRC. In previous version,
43423 the checksum was using a representation with all letter being
43424 upper-case. With the new implementation (using CRC) we do not remove
43425 the 32th bit of the CRC, so we can have an upper-case starting letter
43426 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43427 It is ambigous since the CRC was optional and could be followed by
43428 options like EB, EE. So now this routines uses lower-case letter for
43429 the hexadecimal representation. Strange enough only lower case letters
43430 where checked in Scan_ALI (even if this was not a possible case).
43432 * gnatvsn.ads (Library_Version): changed to 3.15a.
43434 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43437 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
