2245 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
2246 Orig_Prev to Prev in the case where the actual is N_Function_Call or

4423 consistent way. We used to rely in this predicate on the privateness of
4424 the designated type and its ancestors, but depending on the currently

4440 Add missing escaping of all-caps word 'CPP' in error messages.
4441 (Build_Discriminated_Subtype): Do not inherit representation clauses
4442 from parent type if subtype already carries them, because they are
4443 inherited earlier during derivation and already include those that may
4444 come from a partial view.

4482 operation of an RACW stub type (these primitives are only executed
4483 through dispatching, never through static calls).
4484 (Collect_Interps): When only one interpretation has been found, set N's
4485 Entity and Etype to that interpretation, otherwise Entity and Etype may
4486 still refer to an interpretation that was ignored by Add_One_Interp,
4487 in which case would end up with being marked as not overloaded but with
4488 an Entity attribute not pointing to its (unique) correct interpretation.

8747 subprogram body that acts as its own spec may not have a non-private
8748 WITH clause on a private sibling.
8749 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
8750 child unit is a renaming, create an implicit with_clause on that
8751 parent, and not on the unit it renames, to prevent visibility errors

8798 of Related_Interface to Related_Type.
8799 (Record_Type_Declaration): Minor reordering of calls to decorate the

8818 (Process_Implicit_Dereference_Prefix): If the prefix has an incomplete
8819 type from a limited_with_clause, and the full view is available, use it

8848 Gary Dismukes <dismukes@adacore.com>
8850 * sem_ch9.adb (Analyze_Requeue): Add a local flag to capture whether a
8851 requeue statement is dispatching. Do not emit an error when the name is

8855 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
8856 Timed_Entry_Call): Analyze the triggering statement as the first step of
8857 the processing. If this is a dispatching select, postpone the analysis
8858 of all select statements until the Expander transforms the select. This
8859 approach avoids generating duplicate identifiers after the Expander has
8860 replicated some of the select statements. In case the Expander is
8861 disabled, perform regular analysis.
8862 (Check_Triggering_Statement): New routine.
8863 (Analyze_Requeue): Exclude any interpretations that are not entries when
8864 checking overloaded names in a requeue. Also test type conformance for

8873 for the defaulted actual.
8875 2007-12-13 Geert Bosch <bosch@adacore.com>
8877 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

9433 Add Unreferenced and Warnings (Off) pragmas for cases of
9434 variables modified calls where they are IN OUT or OUT parameters and
9435 the resulting values are not subsequently referenced. In a few cases,
9436 we also remove redundant code found by the new warnings.

9454 * ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
9456 (Xref_Record): Change type for Line, since in the case of a reference to
9457 a predefined entity (as happens for array index types), the line is set
9459 Add support for parsing multiple array index types info, or
9460 multiple inherited interfaces info. This information cannot be stored
9461 in Xref_Entity_Record, which only supports a single instance of Tref_*,
9462 and is therefore stored in the list of references instead. It has a
9463 special treatement later on in tools that use this information.
9465 2007-10-15 Tristan Gingold <gingold@adacore.com>
9467 * debug.adb: Document use of -gnatd.a and -gnatd.I
9469 * layout.adb: On OpenVMS -gnatd.a disables alignment optimization.

9473 * exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
9474 Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
9475 care of access to class-wide interface types plus removal of bizarre
9476 conversion of tagged object to access type (reported by Gary
9477 Dismukes). After this patch there is no need to perform any
9478 additional management on these nodes in Expand_Interface_Actuals.
9480 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
9481 that handles use of 'Access and 'Unchecked_Access applied to
9482 actuals covering interface types. Such code is now
9483 centralized in Expand_N_Attribute_Reference.
9485 2007-10-15 Ed Schonberg <schonberg@adacore.com>
9487 * exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
9488 of tagged types whose ultimate ancestor is a CPP type.
9489 (Freeze_Array_Type): For a packed array type, generate an initialization
9490 procedure if the type is public, to handle properly a client that
9491 specifies Normalize_Scalars.
9493 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9495 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

9513 (passing'Unrestricted_Access of nested subprograms to Sort) with use of
9514 the generic Heap_Sort_G, in order to avoid trampolines.

9519 * vx_stack_info.c: New file.
9521 * i-forbla-unimplemented.ads: New file.
9523 * Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
9524 for unsupported configurations; use it on VMS targets instead of the
9526 (EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
9527 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
9528 used by VxWorks targets to have access to task-specific data and be
9529 able to extract the stack boundaries for stack checking.
9530 Use system-vms-ia64.ads on ivms.
9532 * Make-lang.in: Update dependencies.
9534 * sysdep.c (__gnat_get_stack_info): Move to a standalone file

9551 95 reserved word in its name.
9552 (Process_Project_Level_Array_Attributes): Process new attribute
9553 Runtime_Library_Dir.
9555 * prj-part.adb (Parse_Single_Project): Do not check the name of the

9571 2007-10-15 Gary Dismukes <dismukes@adacore.com>
9573 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
9574 association for an access component, add an association with null as
9575 the expression. Remove testing for array subtypes and the setting in
9576 that case of Ctyp to the array component type, which prevented proper
9577 inclusion of an association for null-initialized arrays. Collapse
9578 condition that tests for array subtypes into just a test of
9579 Is_Partially_Initialized_Type (which already covers arrays anyway).
9581 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9583 * sem_ch12.adb: Minor code reformatting.
9584 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to
9585 find the parent package which may have been hidden by local

9590 * sem_ch3.adb (Build_Derived_Concurrent_Type): Set the Is_Constrained
9591 flag of derived concurrent types, taking into account the flag setting
9592 on the parent subtype and any new set of discriminants.
9594 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
9596 * sem_ch4.adb: Minor code and comment reformatting.
9597 (Analyze_Allocator): When the designated type of an unconstrained
9598 allocator is a record with unknown discriminants or an array with
9599 unknown range bounds, emit a detailed error message depending on the
9600 compilation mode and whether the designated type is limited.

9675 to generate g-soccon-vms.ads.
9677 * atree.adb: Add ??? comment

9733 type of file_info_ptr parameter.
9734 If mapped location support is enabled, create the isomorphic mapping
9735 between source files and line maps.
9736 (Sloc_to_locus): If mapped location support is enabled, translate
9737 source location into mapped location.
9738 (annotate_with_node): Rename into set_expr_location_from_node.

9764 * a-calend-vms.adb, a-calend.adb:
9765 Add a section on leap seconds control along with two entities used to
9766 enable and disable leap seconds support. The array Leap_Second_Times is
9767 now constant and contains hard time values pre-generated. Remove
9768 all elaboration code used to populate the table of leap seconds.
9771 Add entity Leap_Seconds_Support to the list of global run-time variables
9772 along with a comment on its usage and values.
9773 (Gen_Adainit_Ada): Add code to generate the declaration and import of

9829 Eric Botcazou <ebotcazou@adacore.com>
9832 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
9833 indirection added to the HT_Link component of the TSD. This is required
9834 to statically allocate the TSD.
9837 Minor reordering of the declarations in the private part. Required to
9838 add a level of indirection to the contents of the TSD component HT_Link.

9853 purpose Make_DT now declares a separate object that stores the
9854 HT_Link value, and initializes the TSD component with the address
9855 of this new object. The addition of this level of indirection is
9856 required to statically allocate the TSD because the TSD cannot
9857 have variable components.
9858 (Expand_Interface_Conversion): Improve the expanded code.
9859 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
9861 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
9862 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
9863 if we are building static dispatch tables then we must not generate
9864 extra code to register the primitive because the dispatch table will
9865 be built at the end of the library package; otherwise we notify that
9866 we cannot build the static dispatch table.

9889 associated with interface types.
9890 Extensive comment fixes regarding flags that appear in all entities. The
9891 documentation is now consistent for all such flags (there were a number
9892 of errors in the documentation in this regard).
9894 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
9896 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
9897 of these procedures are passed a function call that already has
9898 build-in-place actuals (testing new flag
9899 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
9900 the case where processing continues.
9901 (Expand_Call): If the call is generated from a thunk body then we
9902 propagate the extra actuals associated with the accessibility
9903 level of the access type actuals.
9905 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
9906 of each extra formal of a protected operation to reference the
9907 corresponding extra formal of the subprogram denoted by the
9908 operation's Protected_Body_Subprogram.
9910 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
9911 N_Function_Call nodes.
9913 2007-09-26 Robert Dewar <dewar@adacore.com>
9915 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set

9922 debug variable so that it won't be initialized when pragma
9923 Initialize_Scalars is in effect.
9925 2007-09-26 Gary Dismukes <dismukes@adacore.com>
9927 * freeze.adb (Freeze_Entity): Remove check for preelaborable
9928 initialization of a full view. This is moved to

9932 preelaborable initialization of a full view in entity loop.
9933 (Uninstall_Declarations): If entity is a use-visible compilation unit,
9934 its child units are use-visible only if they are visible child units.
9936 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
9937 whether an expression can be used within a type declaration that
9938 requires preelaborable init.
9939 (Check_Components): Replace inline code that does partial checking for
9940 preelaborable default expressions with call to
9941 Is_Preelaborable_Expression.
9942 (Has_Preelaborable_Initialization): In the case of a generic actual
9943 subtype, (that is, Is_Generic_Actual is True), return the result of
9944 applying Has_Preelaborable_Initialization to the generic actual's base
9947 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
9949 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
9950 call to Jan_1_Day _Of_Week to optimize its performance.
9951 (Is_Leap): Move the routine to the scope of Week_In_Year.
9952 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
9953 weekday on which January 1 falls of Year - 1 and Year + 1. This function
9954 avoids calling Time_Of and Split, thus making it more efficent.
9955 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
9957 * g-calend.ads (Week_In_Year): Change comment to reflect new
9960 2007-09-26 Emmanuel Briot <briot@adacore.com>
9962 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
9963 Command_Line): New types
9964 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
9965 support for defining how switches can be grouped on a command line (as
9966 is the case for -gnatw... for GNAT), and how simple switches can be
9967 used as aliases for more complex switches (-gnatwa is same as
9969 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
9970 (Start, Current_*): New subprograms
9971 Added support for parsing an array of strings in addition to the real
9973 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
9974 be moved from the body to the private part of the spec.
9975 (*): All subprograms now have an extra parameter with default value to
9976 specify which parser should be used. For backward compatibility, it
9977 defaults to parsing the command line of the application. They were also
9978 modified to properly handle cases where each of the argument does not
9979 start at index 1 (which is always true for Ada.Command_Line, but not
9980 when processing any Argument_List).
9981 (Free): New subprogram
9982 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
9983 Argument): New subprograms
9984 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
9985 special characters like ':', '=',... are now handled in a single place,
9986 which makes the code more extensible eventually.
9987 (Getopt, Full_Switch): When the switch was returned as part of the
9988 special character '*', make sure it is prepended by the switch character
9989 ('-' in general), so that the application knows whether "foo" or "-foo"
9990 was specified on the command line.
9992 2007-09-26 Florian Villoing <villoing@adacore.com>
9994 * g-dirope.adb (Remove_Dir): In case we are removing directories
9995 recursively, make sure that if an exception is raised during the
9996 processing, the current working directory is reset to its initial
9997 value before propagating the exception.
9999 2007-09-26 Vincent Celier <celier@adacore.com>
10001 * gnatbind.adb: If there are several ALI files specified and there is
10002 a main program to bind, the first ALI is expected to contain the main
10003 subprogram and the names of the binder generated files will be derived
10004 from the first ALI file name.
10005 (Gnatbind): Fix insertion character in invocation of Error_Msg
10007 2007-09-26 Vincent Celier <celier@adacore.com>

10042 * prj-attr.adb: New attributes Required_Switches (<language>) in
10043 packages Compiler and Binder.
10045 * prj-nmsc.adb: Major rewrite of the processing of configuration
10046 attributes for gprbuild. No impact on GNAT tools.
10048 * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
10049 process configuration attributes: this is done in Prj.Nmsc.Check.

10051 being extended, instead of a shallow copy.
10052 (Process_Project_Tree_Phase_1): New procedure
10053 (Process_Project_Tree_Phase_1): New procedure
10054 (Process): Implementation now uses the two new procedures
10056 * prj-util.adb (Executable_Of): Get the suffix and the default suffix
10057 from the project config, not the tree config that no longer exists.

10082 * sem_ch3.adb (Derive_Subprograms): If the interface parent is a direct
10083 ancestor of the derived type, the operations are inherited from the
10084 primary dispatch table of the parent.

10383 Thomas Quinot <quinot@adacore.com>
10385 * exp_ch3.adb (Predef_Spec_Or_Body): When the type is abstract, only
10386 create an abstract subprogram in the case of 'Input. For 'Output we now
10387 create a real spec/body when the type is abstract, since it can
10388 potentially be called.
10389 (Predefined_Primitive_Bodies): Now allow the creation of a predefined
10390 body for 'Output when the type is abstract (only the creation of the
10391 body for 'Input is excluded when the type is abstract).
10392 (Stream_Operation_OK): Add an additional condition in the return
10393 statement, so that False will be returned for TTS_Stream_Input if the
10394 associated tagged type is an abstract extension. Add comments for
10396 (Expand_N_Object_Declaration): For the case of a shared passive
10397 variable, insert init proc call only after the shared variable
10398 procedures have been processed, because the IP call needs to undergo
10399 shared passive variable reference expansion, which requires these
10400 procedures to be available (and elaborated).
10402 2007-09-10 Vincent Celier <celier@adacore.com>
10404 * prj-env.ads, prj-env.adb (Create_Mapping_File (Language)): Remove

10407 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10409 * sem_aggr.adb (Build_Record_Aggr_Code): If an aggregate component is
10410 given a box association, the type of the component is discriminated,
10411 and the value of the discriminant is the discriminant of the enclosing
10412 type, retrieve its value from the aggregate itself, where it must have
10415 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
10416 to remove other spurious ambiguities on arithmetic operations involving
10417 literals and addresses, on systems where Address is a visible integer
10418 type, when the operator is called in functional notation.
10419 (Try_Primitive_Operation): Within an instance, a call in prefixed form
10420 is legal when the types match, even if the operation is currently
10423 2007-09-10 Ed Schonberg <schonberg@adacore.com>
10425 * sem_ch12.adb (Build_Local_Package): A formal package with no
10426 associations is legal if all formals have defaults. It is not
10427 equivalent to a formal declared with a box.
10429 2007-09-10 Sergey Rybin <rybin@adacore.com>

10460 which a constant renaming is treated as a normal object declaration.
10461 * trans.c (lvalue_required_p) <N_Slice>: New case, extracted from
10462 the N_Indexed_Component case.
10463 <N_Indexed_Component>: Fall through to above case.

10469 try again to get an integral mode for it.
10471 2007-09-07 Eric Botcazou <ebotcazou@adacore.com>
10473 Re-apply accidentally reverted change:
10475 2007-02-07 Andreas Krebbel <krebbel1@de.ibm.com>

10478 get_action_description_for): Replace _Unwind_Word with _uleb128_t
10479 and _Unwind_SWord with _sleb128_t.
10481 2007-09-06 Eric Botcazou <ebotcazou@adacore.com>

10485 2007-09-05 Sandra Loosemore <sandra@codesourcery.com>
10487 * trans.c (Compilation_unit_to_gnu): Use set_cfun.

10534 (Mark_Non_Null): If the node for which we just generated an access check
10535 is a reference to an *in* parameter and the reference appears in the

10538 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10540 * einfo.ads, einfo.adb: New flag Is_Raised (Flag224). Update the

10543 Update the usage of available flag to reflect the addition of Is_Raised.
10544 (Is_Raised, Set_Is_Raised): Bodies of new routines.
10545 (Write_Entity_Flags): Write the status of flag Is_Raised.
10546 (Is_Descendent_Of_Address): New entity flag, to simplify handling of
10547 spurious ambiguities when integer literals appear in the context of an
10548 address type that is a visible integer type.
10550 * sem_ch11.adb (Analyze_Exception_Handler): Add code to warn on local
10551 exceptions never being raised.
10552 (Analyze_Raise_Statement): When analyzing an exception, mark it as being
10555 2007-08-31 Javier Miranda <miranda@adacore.com>
10557 * exp_ch11.adb (Expand_At_End_Handler): Avoid generation of raise
10558 statement when compiling under restriction No_Exceptions_Proparation.
10560 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10562 * exp_ch3.adb (Build_Record_Init_Proc): If there is a static
10563 initialization aggregate for the type, generate itype references for
10564 thetypes of its (sub)components, to prevent out-of-scope errors in gigi.
10566 2007-08-31 Gary Dismukes <dismukes@adacore.com>
10568 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
10569 library-level package renaming, pass the declaration associated with
10570 the renaming's special debug variable to Qualify_Entity_Names to ensure
10571 that its encoded name is properly qualified.
10573 * exp_dbug.adb (Qualify_All_Entity_Names): Check for a variable entity
10574 occurring in the list of entities to qualify, and do not attempt to
10575 traverse an entity list in that case. Variables associated with
10576 ` library-level package renamings can now occur in the table.
10578 * exp_dbug.ads: Revise documentation of the encoding for renaming
10581 2007-08-31 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
10583 * layout.adb (Layout_Type): Use Underlying_Type to determine whether an
10584 access type points to an unconstrained array.
10586 2007-08-31 Hristian Kirtchev <kirtchev@adacore.com>
10588 * restrict.adb, namet.adb, par-util.adb: Remove redundant type
10591 * sem_res.adb (Resolve_Qualified_Expression): Add machinery to detect
10592 simple redundant qualifications. The check is performed whenever the
10593 expression is a non-overloaded identifier.
10594 (Resolve_Type_Conversion): Enchance the redundant type conversion check
10595 to include loop parameters.
10596 (Valid_Conversion): Avoid generation of spurious error message.

10600 * par-ch4.adb (P_Simple_Expression): Fold long sequences of
10601 concatenations of string literals into a single literal, in order to
10602 avoid very deep recursion in the front end, which was causing stack
10605 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
10606 string, and the right operand is a string literal (the case of "" &
10607 "..."), optimize by avoiding copying the right operand -- just use the
10608 value of the right operand directly.
10610 * stringt.adb (Store_String_Chars): Optimize by growing the
10611 String_Chars table all at once, rather than appending characters one by
10613 (Write_String_Table_Entry): If the string to be printed is very long,
10614 just print the first few characters, followed by the length. Otherwise,
10615 doing "pn(n)" in the debugger can take an extremely long time.
10617 * sem_prag.adb (Process_Interface_Name): Replace loop doing
10618 Store_String_Char with Store_String_Chars.
10620 2007-08-31 Vincent Celier <celier@adacore.com>

10633 have not been fully analyzed.
10635 2007-08-31 Ed Schonberg <schonberg@adacore.com>
10637 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
10638 flag, for effiency. It is called when analyzing arithmetic operators
10639 and also for actuals in calls that are universal_integers. The flag is
10640 set for the predefined type address, and for any type or subtype
10643 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
10644 Universal_Integer, when the formal is a descendent of address and the
10645 call appears in user code.
10646 (Analyze_Selected_Component): if the prefix is a private extension, the
10647 tag component is visible.
10649 * sem_util.ads, sem_util.adb: Remove Is_Descendent_Of_Address, now an

10708 * misc.c (gnat_type_max_size): Constify.
10710 2007-08-16 Gary Dismukes <dismukes@adacore.com>
10712 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
10713 associated with Standard_Debug_Renaming_Type, to be used as the type of
10714 the special variables whose names provide debugger encodings for
10715 renaming declarations.
10717 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.
10718 (Set_Debug_Renaming_Link): Change to set Node25.
10719 (Write_Field13_Name): Remove case for E_Enumeration_Literal.
10720 (Write_Field25_Name): Add case for E_Variable to output
10721 "Debug_Renaming_Link".
10722 (Write_Field23_Name): Correct the output string for "Limited_View".
10724 * exp_dbug.adb: Add with and use of Tbuild.
10725 (Debug_Renaming_Declaration): Replace creation of an enumeration type
10726 and literal with creation of a variable of type
10727 Standard_Debug_Renaming_Type whose name encodes both the renamed object
10728 and the entity of the renaming declaration.
10729 (Qualify_Entity_Name): Add the delayed qualification of the entity name
10730 part of the name of a variable that has a Debug_Renaming_Link.
10732 * stand.ads (Standard_Debug_Renaming_Type): New Entity_Id denoting a
10733 special type to be associated with variables that provide debugger
10734 encodings for renaming declarations.

10737 Ed Schonberg <schonberg@adacore.com>
10738 Javier Miranda <miranda@adacore.com>
10740 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
10741 ancestor part given by an aggregate to test for an unchecked conversion,
10742 since this can occur in some cases when the ancestor part is a function
10743 call, and we don't want to fall into the recursive call to this
10744 procedure in that case.
10746 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
10747 stream attributes on limited types to account for user-specified
10748 attributes as well as whether Input (resp. Output) becomes available
10749 due to Read (resp. Write) being available for the type. Change Boolean
10750 variable to the more accurate name
10751 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
10752 double-"not" predicate at beginning of return statement to more
10753 understandable form.
10755 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
10756 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
10757 in a block statement and use that as the first statement of the
10758 expanded return rather than incorrectly using the handled sequence as
10759 the first statement.
10761 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
10762 operation, generate an explicit freeze node for it rather than
10763 generating extra formals, to ensure that gigi has the proper order of
10764 elaboration for anonymous subtypes in the signature of the subprograms.
10765 (Build_In_Place_Formal): Move assertion to beginning of loop.
10766 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
10767 applied to a function call (occurs for some cases of 'Input).
10768 (Make_Build_In_Place_Call_In_*): Allow for an unchecked conversion
10769 applied to a function call (occurs for some cases of 'Input).
10771 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
10772 2005, generate an extended return statement enclosing the result object
10775 * freeze.adb (Freeze_Record_Type): Extend the current management of
10776 components that are access type with an allocator as default value: add
10777 missing support to the use of qualified expressions of the
10778 allocator (which also cause freezing of the designated type!)
10779 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
10780 dispatching operation, since extra formals may be needed by calls to
10781 build-in-place functions (such as stream 'Input).
10783 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
10784 formals for 'Constrained and accessibility level in the case of a
10785 predefined dispatching operation.
10787 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
10788 point, no need to find the parent node.
10790 2007-08-16 Javier Miranda <miranda@adacore.com>
10792 * exp_attr.adb (Attribute_Priority): Add missing support for entries
10793 and entry barriers.
10795 2007-08-16 Javier Miranda <miranda@adacore.com>
10797 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
10798 is not really required and can introduce regression with the debugger.
10799 The original problem is fixed with the patch written for checks.adb.
10801 2007-08-16 Thomas Quinot <quinot@adacore.com>
10803 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress
10804 Range_Check on Allocated_Table.
10806 2007-08-16 Vincent Celier <celier@adacore.com>
10808 * make.adb (Collect_Arguments): Call Test_If_Relative_Path with
10809 Including_Non_Switch set to False.
10810 (Gnatmake): For the compiler, call Test_If_Relative_Path with
10811 Including_Non_Switch set to False.
10813 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
10814 parameter Including_Non_Switch, defaulted to True. When
10815 Including_Non_Switch is False, options that are not switches and
10816 appear as relative path are not converted to absolute paths.

10831 from the immediate ancestor of Main_Unit_Entity.
10832 (Install_Limited_Withed_Unit): Do not install the limited view of
10833 package P if P is reachable through an ancestor chain from package C

10840 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
10841 generic for an enclosing instance is a global reference, even though
10842 its scope is the enclosing instance.

10868 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
10869 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
10870 the statement which is being resolved comes from a predefined library
10871 unit, all non-predefined library interpretations are skipped.
10872 (Resolve_Op_Concat): If string concatenation was folded in the parser,
10873 but the "&" is user defined, give an error, because the folding would

10877 the parser has folded a long sequence of concatenations of string
10880 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
10881 and "JMP_BUF" variables as artificial.
10882 (N_String_Literal): Do not use alloca for very long string literals. Use
10883 xmalloc/free instead. Otherwise the stack might overflow.

10930 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
10931 Suppress unmodified in-out parameter warning in some cases
10932 This patch is a also fairly significant change to the way suppressible
10933 checks are handled.
10935 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
10936 needed for access to concurrent record types generated by the expander.
10937 (Generate_Range_Check): When generating a temporary to capture the
10938 value of a conversion that requires a range check, set the type of the
10939 temporary before rewriting the node, so that the type is always
10940 properly placed for back-end use.
10941 (Apply_Float_Conversion_Check): Handle case where the conversion is
10943 (Get_Discriminal): Code reformatting. Climb the scope stack looking
10944 for a protected type in order to examine its discriminants.

10951 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
10952 a-stwisu.adb, a-strsup.adb: Fix warnings for range
10953 tests optimized out.
10955 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
10956 (Get_Allocator_Final_List): For the case of an anonymous access type
10957 that has a specified Associated_Final_Chain, do not go up to the
10959 (Expand_N_Type_Conversion): Test for the case of renamings of access
10960 parameters when deciding whether to apply a run-time accessibility
10962 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
10963 aggregate code before allocator, and ahead of declaration for
10964 temporary, to prevent access before elaboration when the allocator is
10965 an actual for an access parameter.
10966 (Expand_N_Type_Conversion): On an access type conversion involving an
10967 access parameter, do not apply an accessibility check when the
10968 operand's original node was an attribute other than 'Access. We now
10969 create access conversions for the expansion of 'Unchecked_Access and
10970 'Unrestricted_Access in certain cases and clearly accessibility should
10971 not be checked for those.
10973 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
10974 includes a type conversion of a packed component that has been expanded,
10975 recover the original expression for the object, and use this expression
10976 in the post-call assignment statement, so that the assignment is made
10977 to the object and not to a back-end temporary.
10978 (Freeze_Subprogram): In case of primitives of tagged types not defined
10979 at the library level force generation of code to register the primitive
10980 in the dispatch table. In addition some code reorganization has been
10981 done to leave the implementation clear.
10982 (Expand_Call): When expanding an inherited implicit conversion,
10983 preserve the type of the inherited function after the intrinsic
10984 operation has been expanded.
10986 * exp_ch2.ads, exp_ch2.adb
10987 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
10988 of an entry formal appearing in an assignment statement does not assign
10990 (Expand_Current_Value): Instead of calling a routine to determine
10991 whether the prefix of an attribute reference should be optimized or
10992 not, prevent the optimization of such prefixes all together.
10994 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
10995 component whose prefix is known to be of an access type is an implicit
10996 dereference and does not assign to the prefix.
10998 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10999 Robert Dewar <dewar@adacore.com>
11001 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
11002 itype is visited, make an entry into table to link associated node and
11004 Add comments and correct harmless error in Build_NCT_Hash_Tables
11005 (Array_Aggr_Subtype): Associate each itype created for an index type to
11006 the corresponding range construct, and not to the aggregate itself. to
11007 maintain a one-to-one correspondence between itype and its associated
11008 node, to prevent errors when complex expression is copied.
11009 Fix mishandling of multiple levels of parens
11011 * sem_aggr.adb: Create a limited view of an incomplete type, to make
11012 treatment of limited views uniform for all visible declarations in a
11013 limited_withed package.
11014 (New_Copy_Tree): If hash table is being used and itype is visited,
11015 make an entry into table to link associated node and new itype.
11016 (Resolve_Record_Aggregate): Do not add an others box association for a
11017 discriminated record component that has only discriminants, when there
11018 is a box association for the component itself.
11020 * par-ch4.adb: Fix mishandling of multiple levels of parens
11022 2007-08-14 Robert Dewar <dewar@adacore.com>

11058 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
11059 to make treatment of limited views uniform for all visible declarations
11060 in a limited_withed package.
11061 Improve warnings for in out parameters
11062 (Set_Related_Interaface/Related_Interface): Allow the use of this
11063 attribute with constants.
11064 (Write_Field26_Name): Handle attribute Related_Interface in constants.
11065 Warn on duplicate pragma Preelaborable_Initialialization
11067 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
11068 generation of a freezing node to ensure proper management of null
11069 excluding access types in the backend.
11070 (Create_Extra_Formals): Test base type of the formal when checking for
11071 the need to add an extra accessibility-level formal. Pass the entity E
11072 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
11073 originally being done in a couple of cases), to ensure that the
11074 Extra_Formals list gets set on the entity E when the first entity is
11076 (Conforming_Types): Add missing calls to Base_Type to the code that
11077 handles anonymous access types. This is required to handle the
11078 general case because Process_Formals builds internal subtype entities
11079 to handle null-excluding access types.
11080 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11081 functions that need it, even when not marked Requires_Overriding.
11082 Improve warnings for in out parameters
11083 (Analyze_Function_Return): Warn for disallowed null return
11084 Warn on return from procedure with unset out parameter
11085 Ensure consistent use of # in error messages
11086 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
11087 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
11088 the implicit conversion of the expression done for anonymous access
11089 types. This is required to generate the code of the null excluding
11090 check (if required).
11092 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
11093 A formal parameter is never publicly referenceable outside of its body.
11094 (Check_References): For an unreferenced formal parameter in an accept
11095 statement, use the same warning circuitry as for subprogram formal
11097 (Warn_On_Unreferenced_Entity): New subprogram, taken from
11098 Output_Unreferenced_Messages, containing the part of that routine that
11099 is now reused for entry formals as described above.
11100 (Goto_Spec_Entity): New function
11101 (Check_References): Do not give IN OUT warning for dispatching operation
11102 Improve warnings for in out parameters
11103 (Test_Ref): Check that the entity is not undefinite before calling
11104 Scope_Within, in order to avoid infinite loops.

11110 Gary Dismukes <dismukes@adacore.com>
11112 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
11113 (Expand_N_Attribute_Reference): Further unify the handling of the
11114 three forms of access attributes, using common code now for all three
11115 cases. Add a test for the case of applying an access attribute to
11116 an explicit dereference when the context is an access-to-interface
11117 type. In that case we need to apply the conversion to the prefix
11118 of the explicit dereference rather than the prefix of the attribute.
11119 (Attribute_Version, UET_Address): Set entity as internal to ensure
11120 proper dg output of implicit importation.
11121 (Expand_Access_To_Type): Removed.
11122 (Expand_N_Attribute_Reference): Merge the code from the three cases
11123 of access attributes, since the processing is largely identical for
11124 these cases. The substantive fix here is to process the case of a
11125 type name prefix (current instance case) before handling the case
11126 of interface prefixes.

11131 Robert Dewar <dewar@adacore.com>
11133 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
11134 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
11135 type that is an anonymous access to controlled object, establish
11136 an associated finalization chain to avoid corrupting the global
11137 finalization list when a dynamically allocated object designated
11138 by such a component is deallocated.
11139 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
11140 functions that need it, even when not marked Requires_Overriding.
11141 (Initialize_Tag): Replace call to has_discriminants by call to
11142 Is_Variable_Size_Record in the circuitry that handles the
11143 initialization of secondary tags.
11144 (Is_Variable_Size_Record): New implementation.
11145 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
11146 Suppress_Initialization pragma for a derived type.
11147 (Is_Variable_Size_Record): New subprogram.
11148 (Build_Offset_To_Top_Functions): New implementation that simplifies the
11149 initial version of this routine and also fixes problems causing
11150 incomplete initialization of the table of interfaces.
11151 (Build_Init_Procedure): Improve the generation of code to initialize the
11152 the tag components of secondary dispatch tables.
11153 (Init_Secondary_Tags): New implementation that simplifies the previous
11154 version of this routine.
11155 (Make_DT): Add parameter to indicate when type has been frozen by an
11156 object declaration, for diagnostic purposes.
11157 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
11158 diagnose attemps to freeze a subprogram when some untagged type of its
11159 profile is a private type whose full view has not been analyzed yet.
11160 (Freeze_Array_Type): Generate init proc for packed array if either
11161 Initialize or Normalize_Scalars is set.
11162 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
11163 constructing the new profile, copy the null_exclusion indicator for each
11164 parameter, to ensure full conformance of the new body with the spec.
11166 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
11167 Create wrappers for constructor functions that need it, even when not
11168 marked Requires_Overriding.
11169 (Covers): Handle properly designated types of anonymous access types,
11170 whose non-limited views are themselves incomplete types.
11171 (Add_Entry): Use an entity to store the abstract operation which hides
11173 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
11174 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
11175 initialization aggregate.
11176 (Function_Interp_May_Be_Hidden): Rename to
11177 Function_Interp_Has_Abstract_Op.
11178 (Has_Compatible_Type): Remove machinery that skips interpretations if
11179 they are labeled as potentially hidden by an abstract operator.
11180 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
11181 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
11182 (Write_Overloads): Output the abstract operator if present.
11183 (Add_Entry): Before inserting a new entry into the interpretation table
11184 for a node, determine whether the entry will be disabled by an abstract
11186 (Binary_Op_Interp_May_Be_Hidden): New routine.
11187 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
11189 (Function_Interp_May_Be_Hidden): New routine.
11190 (Has_Compatible_Type): Do not consider interpretations hidden by
11191 abstract operators when trying to determine whether two types are
11193 (Has_Hidden_Interp): New routine.
11194 (Set_May_Be_Hidden_Interp): New routine.

11200 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
11201 types declared in the declarative part of a nested package body or in
11202 the proper body of a stub.
11203 (Set_All_DT_Position): Add missing check to avoid wrong assignation
11204 of the same dispatch table slot to renamed primitives.
11205 (Make_Select_Specific_Data_Table): Handle private types.
11206 (Tagged_Kind): Handle private types.
11207 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
11208 output of implicit importation and exportation.
11209 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
11210 first formal of the thunk is always associated with the controlling
11211 type. In addition perform the following code cleanup: remove formal
11212 Thunk_Alias which is no longer required, cleanup evaluation of the
11213 the controlling type, and update the documentation.
11214 Replace occurrence of Default_Prim_Op_Count by
11215 Max_Predef_Prims. Addition of compile-time check to verify
11216 that the value of Max_Predef_Prims is correct.
11217 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
11218 (Make_DT): Add parameter to indicate when type has been frozen by an
11219 object declaration, for diagnostic purposes.
11220 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
11221 construction of statically allocated dispatch tables.
11222 (Make_DT): In case of library-level tagged types export the declaration
11223 of the primary tag. Remove generation of tags (now done by Make_Tags).
11224 Additional modifications to handle non-static generation of dispatch
11225 tables. Take care of building tables for asynchronous interface types
11226 (Make_Tags): New subprogram that generates the entities associated with
11227 the primary and secondary tags of Typ and fills the contents of Access_
11228 Disp_Table. In case of library-level tagged types imports the forward
11229 declaration of the primary tag that will be declared later by Make_DT.
11230 (Expand_Interface_Conversion): In case of access types to interfaces
11231 replace an itype declaration by an explicit type declaration to avoid
11232 problems associated with the scope of such itype in transient blocks.

11235 Ed Schonberg <schonberg@adacore.com>
11236 Javier Miranda <miranda@adacore.com>
11238 * exp_util.ads, exp_util.adb:
11239 This patch replaces a number of occurrences of explicit tests for N_Null
11240 with calls to Known_Null. This improves tracking of null values, since
11241 Known_Null also catches null constants, and variables currently known to
11242 be null, so we get better tracking.
11243 (Ensure_Defined): create an itype reference only in the scope of the
11245 (Side_Effect_Free): A selected component of an access type that
11246 denotes a component with a rep clause must be treated as not
11247 side-effect free, because if it is part of a linked structure its
11248 value may be affected by a renaming.
11249 (Expand_Subtype_From_Expr): For limited objects initialized with build
11250 in place function calls, do nothing; otherwise we prematurely introduce
11251 an N_Reference node in the expression initializing the object, which
11252 breaks the circuitry that detects and adds the additional arguments to
11253 the called function. Bug found working in the new patch for statically
11254 allocated dispatch tables.
11255 (Is_Library_Level_Tagged_Type): New subprogram.
11256 (Remove_Side_Effects): If the expression of an elementary type is an
11257 operator treat as a function call.
11258 (Make_Literal_Range): If the index type of the array is not integer, use
11259 attributes properly to compute the constraint on the resulting aggregate
11262 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
11263 class-wide type whose base type is an incomplete private type, leave
11264 class-wide type unfrozen so that freeze nodes can be generated
11265 properly at a later point.
11266 (Freeze_Entity, array case): Handle case of pragma Pack and component
11267 size attributre clause for same array.
11269 2007-08-14 Vincent Celier <celier@adacore.com>
11271 * prj.ads, prj.adb: Update Project Manager to new attribute names for
11273 Allow all valid declarations in configuration project files
11274 (Reset): Initialize all tables and hash tables in the project tree data
11275 Major update of the Project Manager and of the project aware tools,
11276 including gprmake, so that the same sources in the GNAT repository

11913 * sem_ch12.ads, sem_ch12.adb (Instantiate_Type): If the formal is a
11914 derived type with interface progenitors use the analyzed formal as the
11915 parent of the actual, to create renamings for all the inherited
11916 operations in Derive_Subprograms.
11917 (Collect_Previous_Instances): new procedure within of
11918 Load_Parent_Of_Generic, to instantiate all bodies in the compilation
11919 unit being loaded, to ensure that the generation of global symbols is
11920 consistent in different compilation modes.
11921 (Is_Tagged_Ancestor): New function testing the ancestor relation that
11922 takes progenitor types into account.
11923 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
11924 traversing over the primitives of the formal and actual types to locate
11925 any abstract subprograms of the actual type that correspond to a
11926 nonabstract subprogram of the formal type's ancestor type(s), and issue
11927 an error if such is found.
11928 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
11929 Instantiate_Package_Body, Instantiate_Subprogram_Body):
11930 Remove bogus guard around calls to Inherit_Context.
11931 (Reset_Entity): If the entity is the selector of a selected component
11932 that denotes a named number, propagate constant-folding to the generic
11933 template only if the named number is global to the generic unit.
11934 (Set_Instance_Env): Only reset the compilation switches when compiling
11935 a predefined or internal unit.
11937 2007-08-14 Ed Schonberg <schonberg@adacore.com>

11940 parameter to determine whether operation applies to the prefix.
11941 (Complete_Object_Operation): If actual has an access type and
11942 controlling formal is not an in_parameter, reject the actual if it is
11943 an access_to_constant type.
11944 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
11945 type, the candidate operations are found in the scope of declaration of
11946 the type, because the type has no primitive subprograms.
11947 (Analyze_Selected_Component): If prefix is class-wide, and root type is
11948 a private extension, only examine visible components before trying to
11949 analyze as a prefixed call.
11950 Change Entity_List to Type_To_Use, for better readability.
11951 (Has_Fixed_Op): Use base type when checking whether the type of an

11960 formal At_Any_Place indicating, when True, that we want to test for
11961 availability of the stream attribute at any place (as opposed to the
11962 current visibility context only).
11963 (Missing_Read_Write_Attributes): A stream attribute is missing for the
11964 purpose of enforcing E.2.2(8) only if it is not available at any place.
11965 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
11966 when checking the legality of an extension aggregate in a preelaborable
11967 package. Treat the literal null as a valid default expression in a
11968 component declaration for a type with preelaborable initialization.
11969 A limited interface is a legal progenitor for the designated type of a
11970 remote access to class-wide type.

11982 mark the full view as referenced, to prevent spurious warnings.
11983 (Find_Selected_Component, Has_Components): Handle properly non-limited
11984 views that are themselves incomplete types.
11985 Handle interfaces visible through limited-with clauses.
11986 (Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
11987 subprogram generic actual for which we have generated a renaming.
11988 Warn when the renaming introduces a homonym of
11989 the renamed entity, and the renamed entity is directly visible.

11998 the allocator is not a coextension.
11999 (Resolve): Skip an interpretation hidden by an abstract operator only
12000 when the type of the interpretation matches that of the context.
12001 (Resolve): When looping through all possible interpretations of a node,
12002 do not consider those that are hidden by abstract operators.
12003 (Resolve_Actuals): When verifying that an access to class-wide object
12004 is an actual for a controlling formal, ignore anonymous access to
12005 subprograms whose return type is an access to class_wide type.
12006 (Resolve_Slice): If the prefix of the slice is a selected component
12007 whose type depends on discriminants, build its actual subtype before
12008 applying range checks on the bounds of the slice.
12009 (Valid_Conversion): In an instance or inlined body, compare root types,
12010 to prevent anomalies between private and public views.
12011 (Resolve): Improve error message for ambiguous fixed multiplication
12012 expressions that involve universal_fixed multiplying operations.

12032 elabration statements, register the package with the name server
12033 at the beginning, not at the end, of the elaboration statements so
12034 that they can create remote access to subprogram values that designate
12035 remote subprograms from the package.

12039 * g-catiio.adb (Image): For the case of %s, use Ada.Calendar.Time
12040 values to compute the number of seconds since the Unix Epoc in order to

13163 an unconstrained array type, and the expression is a slice, use the
13164 bounds of the slice to construct the required constraint checks.
13165 Improve NOT NULL error messages

13183 Arnaud Charlet <charlet@adacore.com>
13185 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
13186 applicable to types that have the With_Type flag set. Returns the
13187 non-limited view of the type, if available, otherwise the type itself.
13188 For class-wide types, there is no direct link in the tree, so we have
13189 to retrieve the class-wide type of the non-limited view of the Etype.
13190 New attributes Static_Initialization and Static_Elaboration_Desired.
13191 Remove the pragma Thread_Body, and the associated flag
13192 Is_Thread_Body in entities, and all related code.

13206 (Root_Type): Handle properly subtypes of class-wide-types.
13209 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
13210 class-wide types visible through limited-with clauses.
13211 (Try_Primitive_Operation): When examining all primitive operations of a
13212 tagged type, do not consider subprograms labeled as hidden unless they
13213 belong to a private generic type with a tagged parent.
13214 (Try_Object_Operation): Extensive rewriting, to handle properly various
13215 overloading cases, when several ancestors may have class-wide operations
13216 that are possible candidates, and when the overloaded functions return
13217 array types and have defaulted parameters so that the call may be
13218 interpreted as an indexing.
13219 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
13220 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
13221 successive actuals before analyzing the call itself.
13222 (Try_Primitive_Operation): A primitive operation is compatible with the
13223 prefix if the prefix has a synchronized type and the type of the formal
13224 is its corresponding record, as can be the case when the primitive
13225 operation is declared outside of the body of the type.
13226 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
13227 perform homonym traversal, looking for class-wide operation matches
13228 (formerly done in statements of Try_Class_Wide_Operation). Matches on
13229 access parameters are now restricted to anonymous access types.
13230 (Mark_Allocator): An allocator with a discriminant association parent is
13232 (Try_One_Prefix_Interpretation): If the type of the object is
13233 incomplete, as can be happen when it is a limited view obtained through
13234 a limited_with_clause, the selected component is not part of a prefixed
13236 (Complete_Object_Operation): Diagnose properly an object that is not
13237 aliased when the corresponding controlling formal is an access
13239 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
13240 ambiguous calls in prefixed notation, where two primitives differ only
13241 in that the controlling argument of one is an access parameter.
13243 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
13244 whether a function that returns an unconstrained type can be inlined.
13245 (Process_Formals): Diagnose properly the illegal use of an incomplete
13246 type in the profile of an access_to_subprogram declaration.
13247 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
13248 operations are attached to the corresponding record.
13249 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
13250 When processing a primitive of a concurrent type which implements an
13251 interface change the type of all controlling formals to that of the
13252 corresponding record type.
13253 (Check_Synchronized_Overriding): Relax the conditional logic when trying
13254 to determine the tagged type to which a primitive belongs.
13255 (Check_Conventions): Capture condition to ignore a primitive operation
13256 (which is shared between the loop in Check_Conventions and the one in
13257 Check_Convention) in a new local function Skip_Check.
13258 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
13259 confusion with Check_Conventions' own Prim_Op local variable.
13260 (Create_Extra_Formals): Test for a tagged result type rather than a
13261 controlling result when determining whether to add a BIP_Alloc_Form
13262 formal and a BIP_Final_List formal to the function.
13263 (Check_Conformance); For parameters that are anonymous access types,
13264 subtype conformance requires that the not null and the constant
13265 indicators must match
13266 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
13267 to retrieve the appropriate type when processing a concurrent type
13268 declared within a generic. Minor comment reformatting. Change invocation
13269 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
13271 (Analyze_Subprogram_Body): If the return type of a function is an
13272 anonymous access to the limited view of a class-wide type, and the
13273 non-limited view of the type is available, update the type of the
13274 function so that code can be generated.
13275 (Process_Formals): In case of access-subtype itype whose designated
13276 type is also an itype (situation that happens now with access to
13277 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
13278 attribute to avoid backend problems.
13279 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
13280 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
13281 anonymous types' designated types are same before testing
13282 Subtypes_Statically_Match.
13283 (Create_Extra_Formals): Test for a named access parameter that is a
13284 controlling formal as an additional condition for adding an
13285 accessibility level formal. This can occur in the subp type created for
13286 dispatching calls in Expand_Dispatching_Call, and allows calling
13287 Create_Extra_Formals from that procedure rather than special-casing the
13288 extra formals there.
13289 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
13290 when the function has a controlling result.
13291 (Check_Returns): Add much more knowledge of the optimization of local
13292 raise statements to gotos, to retain proper warnings in this case.
13293 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
13294 nodes when looking for last statement.
13296 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
13297 class-wide types visible through limited with clauses.
13298 (Add_One_Interp): If the operands are anonymous access types, the
13299 predefined operator on universal_access is immediately visibles
13300 (Find_Unique_Type): Handle anonymous access to subprogram types just as
13301 other anonymous access types.
13302 (Disambiguate): Take into account CIL convention.
13303 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
13305 2007-06-06 Robert Dewar <dewar@adacore.com>

13322 * exp_aggr.ads, exp_aggr.adb:
13323 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
13324 in extension aggregates.
13325 (Flatten): Other conditions being met, an aggregate is static if the
13326 low bound given by component associations is different from the low
13327 bound of the base index type.
13328 (Packed_Array_Aggregate_Handled): If the component type is itself a
13329 packed array or record, the front-end must expand into assignments.
13330 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
13331 Init_Pr, instead of Ancestor_Is_Expression.
13332 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
13333 coextension chain root, either generate a list controller or use the
13334 already existing one.
13335 (Static_Array_Aggregate): New procedure to construct a positional
13336 aggregate that can be handled by the backend, when all bounds and
13337 components are compile-time known constants.
13338 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
13339 types covering interface types into assignments.
13340 (Replace_Type): move to Build_Record_Aggr_Code.
13341 (Expand_Record_Aggr_Code): if the target of the aggregate is an
13342 interface type, convert to the definite type of the aggregate itself,
13343 so that needed components are visible.
13344 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
13345 components and the context is an extended return statement do not
13346 create a transient block for it, to prevent premature finalization
13347 before the return is executed.
13348 (Gen_Assign): Do not generate a call to deep adjust routine if the
13349 component type is itself an array of controlled (sub)-components
13350 initialized with an inner aggregate.
13351 (Component_Check): New name for Static_Check. This name is now more
13352 appropriate, and documentation is added which was missing.
13353 (Component_Check): Add test for bit aligned component value
13354 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
13355 Tagged_Comps, name is more appropriate given added function below.
13356 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

13360 Robert Dewar <dewar@adacore.com>
13362 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
13363 Terminated: Add unchecked type conversion from System.Address to
13364 System.Tasking.Task_Id when calling the predefined primitive
13366 Disable new Ada 05 accessibility check for JVM.NET targets, which
13367 cannot be implemented in a practical way.
13368 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
13369 the sources always references the tag of the actual object. Therefore,
13370 if 'Tag is applied in the sources to class-wide interface objects we
13371 generate code that displaces "this" to reference the base of the object.
13372 (Expand_N_Attribute_Reference, case Size): Return specified size if
13373 known to front end.
13374 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
13375 has code that displaces the pointer of the object to manage interface
13376 types. However this code must not be executed when the prefix is a
13377 subprogram. This bug caused the wrong expansion of the internally
13378 generated assignment that fills the dispatch table when the primitive
13379 is a function returning a class-wide interface type.
13380 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
13381 Set_Attribute_Name for Name_Unaligned_Valid.

13384 Gary Dismukes <dismukes@adacore.com>
13386 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
13387 If the initialization is the equivalent aggregate of the initialization
13388 procedure of the type, do not remove it.
13389 (Expand_N_Attribute_Definition_Clause): Exclude access variables
13390 initialized to null from having their expression reset to empty and

13412 (Analyze_Attribute, case 'Access): If the type of the prefix is a
13413 constrained subtype for a nominal unconstrained type, use its base type
13414 to check for conformance with the context.
13415 (Resolve_Attribute): Remove test of the access type being associated
13416 with a return statement from condition for performing accessibility
13417 checks on access attributes, since this case is now captured by
13418 Is_Local_Anonymous_Access.
13419 (Analyze_Access_Attribute): Set Address_Taken on entity
13420 (Analyze_Attribute, case Address): Set Address_Taken on entity
13421 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
13422 validating an access attribute whose prefix is a current instance.
13423 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
13424 applied to dispatching operations, if freezing is required then we set
13425 the attribute Has_Delayed_Freeze in the prefix's entity.
13426 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
13427 current scope if access of local subprogram taken
13428 (Analyze_Access_Attribute): Check legality of self-reference even if the
13429 expression comes from source, as when a single component association in
13430 an aggregate has a box association.
13431 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
13432 the prefix if it is a protected operation and the attribute is
13433 Unrestricted_Access.
13434 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
13435 reference to the base type of the context, to force a constraint check
13436 when the context is an access subtype with an explicit constraint.
13437 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
13438 node is rewritten as an interface conversion. leave unanalyzed after
13439 resolution, to ensure that type checking against the context will take

13444 Robert Dewar <dewar@adacore.com>
13446 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
13447 wrapper when the full view of the controlling type of an inherited
13448 function that dispatches on result implements interfaces.
13449 (Expand_N_Object_Declaration): In cases where the type of the
13450 declaration is anonymous access, create finalization list for it.
13451 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
13452 if the object has no explicit initialization, to match description of
13453 functionality of pragam Persistent_BSS.
13454 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
13455 new function to build static aggregates, to replace initialization call
13456 when static initialization is desired.

13458 its designated type has controlled anonymous access discriminants.
13459 (Build_Equivalent_Aggregate): New procedure to compute a static

13464 initialization procedure with a copy of the equivalent static aggregate
13466 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
13467 declarations for objects of a class-wide interface type, rather than
13468 just identifiers, to prevent visibility problems.
13469 (Expand_N_Object_Declaration): When expanding the declaration for an
13470 object of a class-wide interface type, preserve the homonym chain of
13471 the original entity before exchanging it with that of the generated
13472 renaming declaration.
13473 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
13474 active, because there is no way to handle the exception.
13475 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
13476 to do a minimum decoration of the Access_Disp_Table list.
13477 (Expand_Record_Controller): Avoid the addition of the controller between
13478 the component containing the tag of a secondary dispatch table and its
13479 adjacent component that stores the offset to the base of the object.
13480 This latter component is only generated when the parent type has
13481 discriminants ---documented in Add_Interface_Tag_Components).
13482 (Apply_Array_Size_Check): Removed, no longer needed.
13483 (Expand_N_Full_Type_Declaration): If the type has anonymous access
13484 components, create a Master_Entity for it only if it contains tasks.
13485 (Build_Init_Procedure): Suppress the tag assignment compiling under
13487 (Freeze_Record_Type): Remove code associated with creation of dispatch
13489 (Init_Secondary_Tags): Update type of actuals when generating calls to
13490 Ada.Tags.Set_Offset_To_Top
13491 (Stream_Operation_OK): Disable use of streams compiling under no
13493 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
13494 if Has_Init_Expression set.
13495 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
13496 Register_Primitive, which provides the same functionality.
13497 (Requires_Init_Proc): Return false in case of interface types.
13498 (Add_Secondary_Tables): Use the new attribute Related_Interface to
13500 (Predefined_Primitive_Freeze): Do not assume that an internal entity
13501 is always associated with a predefined primitive because the internal
13502 entities associated with interface types are not predefined primitives.
13503 Therefore, the call to Is_Internal is replaced by a call to the
13504 function Is_Predefined_Dispatching_Operation.
13505 (Make_Eq_If): When generating the list of comparisons for the
13506 components of a given variant, omit the controller component that is
13507 present if the variant has controlled components.
13509 2007-06-06 Javier Miranda <miranda@adacore.com>
13510 Hristian Kirtchev <kirtchev@adacore.com>
13511 Bob Duff <duff@adacore.com>
13513 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
13514 handle the creation of finalization lists and calls for nested
13515 coextensions when the root of the chains is part of a return statement.
13516 (Inside_A_Return_Statement): New function inside Complete_Coextension_
13518 (Expand_Record_Equality): Skip components that are interface types.
13519 (Displace_Allocator_Pointer): Add missing support for interface subtypes
13520 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
13521 with Rewrite_Coextension. Change the condition for detecting coextension
13523 (Is_Local_Access_Discriminant): Removed.
13524 (Rewrite_Coextension): New routine which rewrites a static coextension
13525 as a temporary and uses its unrestricted access in the construction of
13527 (Complete_Coextension_Finalization): New routine. Generate finalization
13528 attachment calls to all delayed coextensions.
13529 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
13530 the allocator is not a coextension itself and has delayed coextensions.
13531 If the current allocator is controlled, but also a coextension, delay
13532 the generation of the finalization attachment call.
13533 Rename local variable "Node" to "Nod" in order to avoid confusion with
13535 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
13536 limited types that are not inherently limited. Such an allocator is
13537 illegal, but is generated by the expander for a return statement, to
13538 copy the result onto the secondary stack. This is the only case where a
13539 limited object can be copied. Generate code to displace the pointer
13540 to the object if the qualified expression is a class-wide interface
13541 object. Such displacement was missing and hence the copy of the object
13543 (Apply_Accessibility_Check): Handle allocated objects initialized in
13545 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
13546 and Expand_Allocator_Expression. Allocating class-wide interface objects
13547 this routine displaces the pointer to the allocated object to reference
13548 the component referencing the corresponding secondary dispatch table.
13549 Expand_Allocator_Expression): Add missing support to allocate class-wide
13550 interface objects initialized with a qualified expression.
13551 (Get_Allocator_Final_List): Test for an anonymous access type that is a
13552 function result type, and use the finalization list associated with the
13553 function scope in that case (such an anonymous type should not be
13554 treated like an access parameter's type).
13556 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13557 Gary Dismukes <dismukes@adacore.com>
13558 Javier Miranda <miranda@adacore.com>
13560 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
13561 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
13562 required exception handler.
13563 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
13564 properly the case of a function whose return type is a limited
13565 class-wide interface type. Modify the code of the accessibility
13566 check to handle class-wide interface objects. In this case we need to
13567 displace "this" to reference the primary dispatch table to get access
13568 to the TSD of the object (to evaluate its accessibility level).
13569 (Expand_N_Extended_Return_Statement): Test for a tagged result type
13570 rather than a controlling result as one of the conditions for
13571 generating tests of the implicit BIP_Alloc_Form formal. The
13572 initialization assignment is also handled according to whether the
13573 result is tagged instead of controlling.
13574 In the case where the init assignment is inserted in the "then" part of
13575 the allocation conditional, rewrite the target to be a dereference of
13576 the implicit BIP_Object_Access formal.
13577 If the returned value is unconstrained and created on the secondary
13578 stack, mark the enclosing block and function so that the secondary
13579 stack is not reclaimed on return.
13580 Treat returns from functions with controlling results similarly to
13581 returns from functions with unconstrained result subtypes.
13582 If the object returned is unconstrained, and an allocator must be
13583 created for it, analyze the allocator once the block for the extended
13584 return is installed, to ensure that finalizable components
13585 of the expression use the proper finalization list. Guard the call to
13586 Move_Final_List with a check that there is something to finalize.
13587 (Make_Tag_Ctrl_Assignment): Use "old" handling
13588 of controlled type assignment for virtual machines, since new code uses
13589 unsupported features (such as direct access to bytes in memory).
13591 2007-06-06 Gary Dismukes <dismukes@adacore.com>
13592 Ed Schonberg <schonberg@adacore.com>
13594 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
13595 accessibility actual, check for the case of an aliased object that has
13596 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
13597 we fall into processing for the attribute rather than the name of the
13599 (Expand_Inline_Call): If an actual is a literal, and the corresponding
13600 formal has its address taken in the body, create a temporary to capture
13601 value. If the return type is a limited interface, do not treat the
13602 return value as Controlled.
13603 (Is_In_Place_Function): If the return type is a limited interface,
13604 treat as returning in place. The actual returned object may not always
13605 be limited, but the caller has to assume that it is returned in place.
13606 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
13607 context of an allocator, use the correct finalization chain (that is,
13608 the chain belonging to the access type, rather than the chain belonging
13609 to the current scope).
13610 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
13611 result type rather than a controlling result as a precondition for
13612 adding an allocation form actual to a build-in-place call.
13613 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
13614 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
13615 primitive in the dispatch tables. This work is now done by Make_DT when
13616 the type is frozen.
13617 (Register_Predefined_DT_Entry): Removed.
13618 (Add_Return): If end label is not present, use sloc of last statement
13619 for generated return statement in procedure, for better gdb behavior
13621 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
13622 object address nodes to ensure proper processing by routines like
13624 (Expand_Call): Fix generation of validity check for parameter
13625 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
13626 the allocation form parameter if the result subtype is constrained,
13627 except when the function has a controlling result.
13628 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
13629 rather than Is_Controlled and Has_Controlled_Component, since we want to
13630 include class-wide result types in this treatment. Also test for a
13631 controlling result, since that also requires passing a finalization
13633 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
13634 even when the result subtype is constrained, to handle calls involving
13635 controlling results.
13636 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
13637 is now called even when the result subtype is constrained, to handle
13638 calls involving controlling results.
13639 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
13640 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
13641 now performs the test).
13642 (Make_Build_In_Place_Call_In_Object_Declaration):
13643 Add_Alloc_Form_Actual_* is now called even when the result subtype is
13644 constrained, to handle calls involving controlling results.
13645 (Add_Return): Accomodate rewritten pattern from local raise to goto
13646 transformation, so that we still recognize an transfer statement
13647 and do the right thing here in that case.
13648 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
13649 and end of subprogram code.
13650 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
13651 support for primitives that are functions (without formals) with a
13652 controlling result.
13653 (Inherited_From_Formal): If the actual subtype has not generic parent
13654 type, it is not an actual for a formal derived type, and there is no
13655 operation to inherit from the formal.
13657 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13658 Thomas Quinot <quinot@adacore.com>
13660 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
13661 inserted cleanup code appropriately for GDB use.
13662 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
13663 exception handler for Deep_Adjust or Deep_Finalize.
13664 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
13665 Raise_From_Controlled_Operation is available, use a call to that
13666 subprogram instead of a plain "raise Program_Error" node to raise
13667 Program_Error if an exception is propagated from an Adjust or Finalize
13669 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
13670 appears in the optional statement list of a triggering alternative, the
13671 scope actions can be inserted directly there, and not in the list that
13672 includes the asynchronous select itself.
13674 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13675 Robert Dewar <dewar@adacore.com>
13676 Hristian Kirtchev <kirtchev@adacore.com>
13678 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
13679 generated exception handler appropriately when debugging generated code.
13680 Deal properly with No_Exception_Propagation restriction mode.
13681 (Expand_N_Abort_Statement): Add an unchecked type conversion from
13682 System.Address to System.Tasking.Task_Id when processing the result of
13683 the predefined primitive _disp_get_task_id.
13684 (Expand_N_Asynchronous_Select): Clarify comment.
13685 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
13686 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
13687 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
13688 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
13689 privals and for generated call to Complete_Entry_Body, for better gdb
13691 (Copy_Result_Type): Utility to construct a parameter and result profile
13692 for protected functions whose return type is an anonymous access to
13694 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
13696 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
13697 point when the local-raise-to-goto transformation has taken place.
13699 2007-06-06 Javier Miranda <miranda@adacore.com>
13700 Nicolas Setton <setton@adacore.com>
13702 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
13703 functionality when the backend is generating code.
13704 Otherwise any serious error
13705 reported by the backend calling the frontend routine Error_Msg
13706 changes the Compilation_Mode to Check_Semantics, disables the
13707 functionality of this routine and causes the generation of
13708 spureous additional errors.
13710 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
13711 debugging information now generated by the compiler for fat-pointer
13713 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
13715 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
13717 2007-06-06 Thomas Quinot <quinot@adacore.com>
13719 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram
13720 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
13721 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
13722 For a remote call to a function with a classwide return type, apply an
13723 E.4(18) check to the returned value.
13724 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
13725 stream attributes of the designated type of an RACW, as they are not
13726 dispatching primitive operations.
13728 2007-06-06 Geert Bosch <bosch@adacore.com>
13730 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
13732 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
13734 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
13735 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
13737 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
13739 2007-06-06 Javier Miranda <miranda@adacore.com>
13741 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
13742 attribute compiling package Ada.Tags under No_Run_Time_Mode.
13744 2007-06-06 Javier Miranda <miranda@adacore.com>
13746 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
13747 deallocation of class-wide interface objects.
13748 (Expand_Dispatching_Constructor_Call): Take into account that if the
13749 result of the dispatching constructor is an interface type, the
13750 function returns a class-wide interface type; otherwise the returned
13751 object would be actual. The frontend previously accepted returning
13752 interface types because Expand_Interface_Actuals silently performed
13753 the management of the returned type "as if" it were a class-wide
13755 (Expand_Dispatching_Constructor_Call): Replace call to
13756 Make_DT_Access_Action by direct call to Make_Function_Call.
13758 2007-06-06 Robert Dewar <dewar@adacore.com>
13759 Ed Schonberg <schonberg@adacore.com>
13761 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
13762 compute masking constant, since we now set Esize properly to the
13764 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
13765 to match the alignment.
13766 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
13767 packed arrays of 8 bits or less.
13769 * freeze.adb (Freeze_Entity): When freezing the formals of a
13770 subprogram, freeze the designated type of a parameter of an access type
13771 only if it is an access parameter.
13772 Increase size of C convention enumeration object
13773 (Freeze_Entity, array type case): Make sure Esize value is properly
13774 adjusted for the alignment if it is known.
13775 (Freeze_Entity, array type case): When checking bit packed arrays for
13776 the size being incorrect, check RM_Size, not Esize.
13777 (Freeze_Record_Type): Check for bad discriminated record convention
13778 (In_Exp_Body): Return true if the body is generated for a subprogram
13779 renaming, either an attribute renaming or a renaming as body.
13780 (Check_Itype): If the designated type of an anonymous access component
13781 is a non-protected subprogram type, indicate that it is frozen, to
13782 prevent out-of-scope freeze node at some subsequent call.
13783 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
13784 only if the subprogram is neither imported nor exported, as well as the
13785 NCA descriptor class if the subprogram is exported.

13790 Gary Dismukes <dismukes@adacore.com>
13792 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
13793 default initialization on an imported object, when there is no
13794 initialization call generated for it.
13795 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
13798 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
13799 Static_Elaboration_Desired.
13800 Remove pragma Thread_Body.
13801 Implement a new pragma No_Body
13802 Removes the Explicit_Overriding pragma
13803 Remove Optional_Overriding pragma
13804 (Prag): Deal with Universal_Aliasing.
13805 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
13806 Pragma_CIL_Constructor): New names.
13808 * sem_cat.adb (Validate_Object_Declaration): An initialization that
13809 uses the equivalent aggregate of a type must be treated as an implicit
13811 (Get_Categorization): Check a unit for pragma Preelaborate only if it
13812 has none of the other categories.
13813 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
13814 to apply Import to an object renaming declaration.
13816 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
13817 from a C++ class should be declared as limited and that it will be
13818 considererd limited.
13819 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
13820 should be declared as limited and that it will be considererd limited.
13821 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
13822 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
13823 (Analyze_Pragma): Deal with Universal_Aliasing.
13824 (Sig_Flags): Likewise.
13825 (Set_Encoded_Interface_Name): Suppress encoding when compiling for AAMP.
13826 (Overflow_Checks_Unsuppressed): New flag.
13827 (Process_Suppress_Unsuppress): Set Overflow_Checks_Unsuppressed.
13828 (Analyze_Pragma [case Pack]): Ignore pragma Pack and post warning in
13829 case of JVM or .NET targets, and compiling user code.
13830 Add debugging convenience routine rv
13832 2007-06-06 Robert Dewar <dewar@adacore.com>
13834 * exp_strm.adb (Make_Field_Attributes): Avoid _Parent components that
13835 are interface type.
13836 (Build_Elementary_Input_Call): For floating-point use right type in the
13837 absence of strange size or stream size clauses.
13838 (Build_Elementary_Write_Call): Same fix
13839 (Has_Stream_Standard_Rep): Returns False if Stream_Size attribute
13840 set to value that does not match base type size.
13842 2007-06-06 Ed Schonberg <schonberg@adacore.com>
13844 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
13845 object of a limited type can be initialized with a call to a function
13846 that returns in place. If the limited type has unknown discriminants,
13847 and the underlying type is a constrained composite type, build an actual
13848 subtype from the function call, as is done for private types.
13849 (Side_Effect_Free): An expression that is the renaming of an object or
13850 whose prefix is the renaming of a object, is not side-effect free
13851 because it may be assigned through the renaming and its value must be
13852 captured in a temporary.
13853 (Has_Controlled_Coextensions): New routine.
13854 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
13855 as is done for other limited types.
13856 (Non_Limited_Designated_Type): new predicate.
13857 (Make_CW_Equivalent_Type): Modified to handle class-wide interface
13859 Remove all handling of with_type clauses.
13861 * par-ch10.adb: Remove all handling of with_type clauses.
13863 * lib-load.ads, lib-load.adb (Load_Main_Source): Do not get the
13864 checksum if the main source could not be parsed.
13865 (Loat_Unit): When processing a child unit, determine properly whether
13866 the parent unit is a renaming when the parent is itself a child unit.
13867 Remove handling of with_type clauses.
13869 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

13884 not be parsed, because of preprocessing errors.
13886 * gnat1drv.adb (gnat1drv): Handle RE_Not_Available gracefully.
13887 (Gnat1drv): Exit with errors if the main source could not be parsed,
13888 because of preprocessing errors.
13889 (Check_Rep_Info): New procedure
13891 2007-06-06 Robert Dewar <dewar@adacore.com>

13895 GNAT.Heap/Bubble_Sort_G is now pure
13897 2007-06-06 Robert Dewar <dewar@adacore.com>
13899 * g-catiio.ads, g-catiio.adb (Image): Check for null picture string
13901 2007-06-06 Robert Dewar <dewar@adacore.com>
13902 Ed Schonberg <schonberg@adacore.com>
13904 * g-comlin.ads, g-comlin.adb:
13905 Add new warning for renaming of function return objects
13907 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
13908 (Tree_Read): Use size of object instead of type'object_size, since the
13909 latter is incorrect for packed array types.
13910 (Tree_Write): Same fix
13912 * opt.ads: Add new warning for renaming of function return objects
13913 (Generating_Code): New boolean variable used to indicate that the
13914 frontend as finished its work and has called the backend to process

14376 associated with dispatch tables is known at compile time.
14377 (Get_Value): If an association in a record aggregate has a box

15718 causes the error message for the ambiguous "X'Access = Y'Access" and
15719 "X'Unrestricted_Access = Y'Access" and so forth to match.
15720 (Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
15721 now that anonymous access to protected operations have their own kind.
15722 (Resolve_Attribute): In case of dispatching call check the violation of
15723 restriction No_Dispatching_Calls.
15724 (Check_Array_Type): Check new -gnatyA array index style option

15727 attempt to derive from a synchronized tagged type.
15728 (Analyze_Type_Declaration): If there is a incomplete tagged view of the
15729 type, inherit the class-wide type already created, because it may
15730 already have been used in a self-referential anonymous access component.
15731 (Mentions_T): Recognize self-referential anonymous access components
15732 that use (a subtype of) the class-wide type of the enclosing type.
15733 (Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
15734 Derived_Type for Prev formal on call to
15735 Check_Anonymous_Access_Components rather than Empty.
15736 (Make_Incomplete_Type_Declaration): Add test for case where the type has
15737 a record extension in deciding whether to create a class-wide type,
15738 rather than just checking Tagged_Present.
15739 (Replace_Anonymous_Access_To_Protected_Subprogram): Procedure applies
15740 to stand-alone object declarations as well as component declarations.
15741 (Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
15742 prevent accidental overwriting when enclosing package appears in
15743 a limited_with_clause.
15744 (Array_Type_Declaration): If the component type is an anonymous access,
15745 the associated_node for the itype is the type declaration itself.

15747 types with abstract interfaces.
15748 (Check_Abstract_Interfaces): New subprogram that verifies the ARM
15749 rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).

15754 with abstract interfaces.
15755 (Analyze_Subtype_Indication): Resolve the range with the given subtype
15756 mark, rather than delaying the full resolution depending on context.

15782 Do not collect arguments if project is externally built.
15783 (Compile_Sources): Do nothing, not even check if the source is up to
15784 date, if its project is externally built.
15785 (Compile): When compiling a predefined source, add -gnatpg
15786 as the second switch, after -c.
15787 (Compile_Sources): Allow compilation of Annex J renames without -a
15788 (Is_In_Object_Directory): Check if the ALI file is in the object
15789 even if there is no project extension.
15790 (Create_Binder_Mapping_File): Only put a unit in the mapping file for
15791 gnatbind if the ALI file effectively exists.
15792 (Initialize): Add the directory where gnatmake is invoked in front of
15793 the path if it is invoked from a bin directory, even without directory
15794 information, so that the correct GNAT tools will be used when spawned

15818 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
15819 when -gnatg is not specified.
15820 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15821 there is no need to generate always a record_definition_node in case
15822 of synchronized interface types.
15823 (SIS_Entry_Active): Initialize global variable to False
15824 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to

15849 (Convert_Aggr_In_Allocator): If the allocator is for an access
15850 discriminant and the type is controlled. do not place on a finalization
15851 list at this point. The proper list will be determined from the

15854 initialize record controller if needed, before the components, to ensure
15855 that they are properly finalized.

15870 succeed in that case, even when the expression originates from a
15871 parameter of the containing subprogram.
15872 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
15873 under No_Dispatching_Calls restriction. During the semantic analysis
15874 we already notified such violation.
15875 (Tagged_Membership): Constant folding. There is no need to check
15876 the tag at run-time if the type of the right operand is non
15877 class-wide abstract.

15891 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
15892 initialize most the TSD components by means of an aggregate.
15893 Modify the declaration of the object containing the TSD
15894 because we now expand code that has a higher level of abstraction.
15895 The TSD has a discriminant containing the Inheritance Depth Level,
15896 value that is used in the membership test but also to fix the size
15897 of the table of ancestors.
15898 (Expand_Interface_Conversion): Insert function body at the closest place
15899 to the conversion expression, to prevent access-before-elaboration
15900 errors in the backend.

15928 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_

15939 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
15940 First (Parameter_Associations ()) with the call to First_Actual that
15941 returns an actual parameter expression for both named and positional

15945 check violation of restriction No_Dispatching_Calls.
15946 (Check_Controlling_Type): A formal of a tagged incomplete type is a
15947 controlling argument.

15953 specify Any_Limited_Interface, and this functionality is already
15954 provided by the function Has_Abstract_Interfaces.
15955 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
15956 support concurrent types implementing interfaces.
15957 (Find_Implemented_Interface): Removed. All the calls to this subprogram
15958 specify kind Any_Limited_Interface, and this functionality is already

15961 CW_Or_Controlled_Type whenever the issue is related to
15962 using or not the secondary stack.

15980 without a corresponding body, generate RACW subprogram bodies in the
15981 spec (just as we do for the task activation call).
15982 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
15983 Is_Abstract_Type. Make sure these are called only when appropriate.

16002 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
16003 a protected version of an operation declared in the private part of
16004 a protected object, because they may be invoked through a callback.
16005 (Set_Privals): If the type of a private component is an anonymous access
16006 type, do not create a new itype for each protected body.
16007 If the body of a protected operation creates
16008 controlled types (including allocators for class-widetypes), the
16009 body of the corresponding protected subprogram must include a

16016 for a possible overriding candidate.
16017 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
16018 hold an actual parameter value since its initialization is separated

16028 Build_From_Any_Call.
16029 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
16030 E_Constant, depending upon Variable formal.
16031 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,

16033 parameter that requires an extra constrained parameter, declare
16034 temporary for actual as a variable, not a constant.
16035 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
16036 the unit being compiled is the one that contains the stub type.
16037 Change primitive operation name for the RACW associated with a RAS
16038 from Call to _Call so it cannot clash with any legal identifier.
16039 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
16041 (Append_RACW_Bodies): New subprogram.
16042 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
16043 Add_Receiving_Stubs_To_Declarations functions.
16044 When expanding a package body, this list correspond to the

16049 registering the receiving stubs at the end of the 'Stmts' list.
16050 (RCI_Package_Locator): Pass the new Version generic formal when
16051 instantiating a RCI_Locator package.
16052 (Build_From_Any_Function): To compute the High bound for an
16053 unconstrained array actual, we add the Low bound with the length.
16054 Thus we must convert the low bound and the length to an appropriate
16055 type before doing the sum.
16056 (Build_Subprogram_Receiving_Stubs, PolyORB):
16057 * Retrieve the extra formals parameters at the
16058 end of the parameter stream.
16059 * Use Move_Any_Value to write back out parameters
16060 after executing the request as it is more efficient
16061 than Copy_Any_Value.
16062 * Build the any containing Extra Formals with the
16063 appropriate typecode.
16064 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
16065 empty Component_List.

16079 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
16080 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
16081 typecode from the Etype. Therefore we retrieve the correct typecode
16082 with a call to Get_Any_Type.
16083 (Copy_Specification): Do controlling formal type substitution based on
16084 Is_Controlling_Formal flag, instead of caller-provided object type.
16085 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
16086 a RACW primitive operation, we might get a subprogram declaration for an
16087 ancestor of the RACW designated type (not for the designated type
16088 itself), in the case where this operation is inherited. In this case we
16089 have no easy means of determining the original tagged type for which
16090 the primitive was declared, so instead we now rely on
16091 Copy_Specification to use the Is_Controlling_Formal flag to determine
16092 which formals require type substitution.

16100 handler unsuitable as a target for a local raise statement.
16101 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
16102 run-time subprogram CW_Membership by call to Build_CW_Membership.
16103 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
16104 by a function call, a temporary must be created before expanding the
16105 Constructor_Call itself, to prevent out-of-order elaboration in the
16106 back-end when stack checking is enabled..

16182 to be checked by gnatstack, which are the naming and the stack packages.
16183 (Check_Files): If no .ci files were specified for gnatstack we add all
16184 the .ci files belonging to the projects, including binder generated
16186 (Non_VMS_Usage): Document that gnatstack accept project file switches.
16187 (GNATCmd): Update the B_Start variable if we are in a VMS environment.
16188 Add gnatstack to the list of commands that use project file related
16189 switches, and get the single attribute Switches from the stack package
16190 in a project file when calling gnatstack. Parse the -U flag for

16235 standard 8bits encoding.
16236 (WS2SU): As above but converting from wide-sring to string.
16237 This is needed as it is necessary to have access to both versions in the
16238 runtime for the form parameter encoding support.
16239 This set of patch add support for the encoding form parameter.
16240 (S2WS): Improve implementation to handle cases where the filename is not
16241 UTF-8 encoded. In this case we default to using the current code page
16242 for the conversion.
16244 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
16245 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

16289 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
16290 __gnat_adjust_context_for_raise.
16291 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
16292 implementation of floating point operations as native x86 targets.
16293 So the FPU should be initialized in the same way using finit. Fix
16294 floating point operations accuracy issues.
16295 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
16296 member in struct sigaction, so as to avoid warning for incompatible

16312 Javier Miranda <miranda@adacore.com>
16314 * lib-xref.ads, lib-xref.adb:
16315 Modify the loop that collects type references, to include interface
16316 types that the type implements. List each of these interfaces when
16317 building the entry for the type.
16318 (Generate_Definition): Initialize component Def and Typ of new entry
16319 in table Xrefs, to avoid to have these components unitialized.
16320 (Output_References): Split Is_Abstract flag into
16321 Is_Abstract_Subprogram and Is_Abstract_Type.
16322 (Generate_Reference): Add barrier to do not generate the warning
16323 associated with Ada 2005 entities with entities generated by the

16365 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
16366 it no longer destroys the contents of Name_Buffer or Name_Len and
16367 non-standard and invalid names are handled better.
16368 (Get_Decoded_Name_String): Improve performance by using
16369 Name_Has_No_Encodings flag in the name table.
16370 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
16371 Used for debugging printouts.

16374 Javier Miranda <miranda@adacore.com>
16375 Bob Duff <duff@adacore.com>
16377 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
16378 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
16379 there is no need to generate always a record_definition_node in case
16380 of synchronized interface types.
16381 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
16382 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
16383 illegal in Ada 95, in cases where it is legal. Change the warnings to
16384 errors in other cases. Don't give the error unless the "not null"
16385 parses properly. Correct the source position at which the error occurs.
16386 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
16387 P_Null_Exclusion, to suppress "not null" warnings.

16439 Entry for pragma Unreferenced_Objects
16441 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
16442 switches, without repetition of "eD". Make sure that last character of
16443 -gnatep= switch is not taken as -gnat switch character.
16444 Complete rewrite of circuit for handling saving compilation options

16463 the default project path, initially done during elaboration of the
16465 If the prefix returned by Sdefault is null, get the prefix from a call
16466 to Executable_Prefix_Path.
16467 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
16470 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
16471 canonical directory name to open the directory from which files are
16473 (Record_Other_Sources): Idem.
16474 (Locate_Directory): Add the possibility to create automatically missing
16475 directories when Setup_Projects is True.

16478 library source copy dir and exec dir.
16480 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
16483 2007-04-06 Robert Dewar <dewar@adacore.com>

16518 full word is no longer compared twice.
16520 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16522 * sem_ch10.adb (Install_Limited_Context_Clauses.
16523 Expand_Limited_With_Clause): Use a new copy of selector name in the
16524 call to Make_With_Clause. This fixes the tree structure for ASIS
16525 purposes. Nothing is changed in the compiler behaviour.
16526 (Process_Body_Clauses): Handle properly use clauses whose prefix is
16527 a package renaming.
16528 (Install_Limited_With_Clauses): Do not install non-limited view when it
16529 is still incomplete.
16531 2007-04-06 Ed Schonberg <schonberg@adacore.com>
16532 Gary Dismukes <dismukes@adacore.com>
16534 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
16535 when capturing size information, instead of base type, which for a
16536 formal array type will be the unconstrained type.
16537 (Analyze_Formal_Object_Declaration): Add check for illegal default
16538 expressions for a formal in object of a limited type.
16539 (Instantiate_Object): Ditto.
16540 (Check_Formal_Package_Instance): Skip entities that are formal objects,
16541 because they were defaulted in the formal package and no check applies
16543 (Check_Formal_Package_Instance): Extend conformance check to other
16544 discrete types beyond Integer.
16545 (Process_Default): Copy directly the unmatched formal. A generic copy
16546 has already been performed in Analyze_Formal_Package.
16547 (Analyze_Associations): If a formal subprogram has no match, check for
16548 partial parametrization before looking for a default, to prevent
16550 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
16551 not set the instantiation environment before analyzing the actuals.
16552 Fixes regression on 8515-003 with implementation of AI-133.
16553 Set_Instance_Env checks whether the generic unit is a predefined
16554 unit, in which case the instance must be analyzed with the latest Ada
16555 mode. This setting must take place after analysis of the actuals,
16556 because the actuals must be analyzed and frozen in the Ada mode extant
16557 outside of the current instantiation.
16558 (Save_Env, Restore_Env): Preserve and restore the configuration
16559 parameters so that predefined units can be compiled in the proper Ada
16561 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
16562 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
16563 and Is_Abstract_Type.
16564 (Analyze_Formal_Package): For better error recovery, Add exception
16565 handler to catch Instantion_Error, which can be raised in
16566 Analyze_Associations

16569 Bob Duff <duff@adacore.com>
16570 Gary Dismukes <dismukes@adacore.com>
16572 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
16573 prefix type is a discriminated subtype of the type of the formal.
16574 (Analyze_Allocator): Collect all coextensions regardless of the context.
16575 Whether they can be allocated statically is determined in exp_ch4.
16576 (Analyze_Selected_Component): If the prefix is a limited view and the
16577 non-limited view is available, use the non-limited one.
16578 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
16579 therefore illegal), suggest a qualified expression rather than a type
16580 conversion, because a type conversion would be illegal in this context.
16581 (Anayze_Allocator): Trace recursively all nested allocators so that all
16582 coextensions are on the corresponding list for the root. Do no mark
16583 coextensions if the root allocator is within a declaration for a stack-
16584 allocated object, because the access discriminants will be allocated on
16586 (Analyze_Call): Remove restriction on calls to limited functions for the
16587 cases of generic actuals for formal objects, defaults for formal objects
16588 and defaults for record components.
16589 (Analyze_Allocator): Before analysis, chain coextensions on the proper
16590 element list. Their expansion is delayed until the enclosing allocator
16591 is processed and its finalization list constructed.
16592 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
16593 for an operation with the given name among the primitive operations of
16594 the corresponding record type.
16595 (Analyze_Selected_Component): If the prefix is a task type that
16596 implements an interface, and there is no entry with the given name,
16597 check whether there is another primitive operation (e.g. a function)
16599 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
16600 properly the indexing of a function call written in prefix form, where
16601 the function returns an array type, and all parameters of the function
16602 except the first have defaults.
16603 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
16604 the original operands, rather than relocating them, for efficiency and
16605 to work properly when an operand is overloaded.
16606 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
16607 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
16608 (Analyze_Selected_Component): If the prefix is a private extension, only
16609 scan the visible components, not those of the full view.
16610 (Try_Primitive_Operation): If the operation is a procedure, collect all
16611 possible interpretations, as for a function, because in the presence of
16612 classwide parameters several primitive operations of the type can match
16613 the given arguments.
16615 2007-04-06 Ed Schonberg <schonberg@adacore.com>

16642 identifier, and be special-cased in Check_Completion.
16643 Mark the full view of the designated type for the RACW associated with
16644 a RAS as Comes_From_Source to get proper view switching when installing
16645 private declarations.
16646 Provite a placeholder nested package body along with the nested spec
16647 to have a place for Append_RACW_Bodies to generate the calling stubs
16648 and stream attributes.

16677 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
16678 dereference of a local object R created as a reference to another
16679 object O, use the access level of O.
16680 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
16681 rather than local Same_Formal_Type, to check whether protected operation
16682 overrides an inherited one.
16683 (Same_Formal_Type): New predicate, used when matching signatures of
16684 overriding synchronized operations, to handle the case when a formal
16685 has a type that is a generic actual.
16686 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
16687 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.

16700 (Is_Parent): New subprogram that determines whether E1 is a parent
16701 of E2. For a concurrent type its parent is the first element of its
16702 list of interface types; for other types this function provides the
16703 same result than Is_Ancestor.
16704 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
16705 (Collect_Synchronized_Interfaces): Removed because the subprogram
16706 Collect_Abstract_Interfaces provides this functionality.

16708 concurrent types and thus avoid undesired code duplication.
16709 (Get_Subprogram_Entity): Handle entry calls.

16752 high bound is constant and the slice is empty. Tidy.
16753 (tree_transform, case N_Op_Not): Handle properly the case where the
16754 operation applies to a private type whose full view is a modular type.
16755 (Case_Statement_To_gnu): If an alternative is an E_Constant with an
16756 Address_Clause, use the associated Expression as the GNAT tree
16757 representing the choice value to ensure the corresponding GCC tree is
16758 of the proper kind.
16759 (maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
16760 instead of just the operands, as the base GCC stabilize_reference does.
16761 <CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
16762 requested; otherwise fail.
16763 (addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.

17023 (mainly static expression evaluation).
17024 Reword some continuation messages
17025 Add some \\ sequences to continuation messages
17026 (Resolve_Call): Refine infinite recursion case. The test has been

17042 Valid_Conversion, to incorporate accessibility checks for arrays of
17043 anonymous access types.
17044 (Valid_Conversion): For a conversion to a numeric type occurring in an
17045 instance or inlined body, no need to check that the operand type is
17046 numeric, since this has been checked during analysis of the template.

17512 (__gnat_set_globals): Now a dummy function.
17513 (__gnat_handle_vms_condition): Feed adjust_context_for_raise with
17514 mechargs instead of sigargs, as the latter can be retrieved from the

17562 (Set_All_DT_Position): Hidden entities associated with abstract
17563 interface primitives are not taken into account in the check for

17576 (Make_DT): If the ancestor of the type is a CPP_Class and we are
17577 compiling under full ABI compatibility mode we avoid the generation of
17578 calls to run-time services that fill the dispatch tables because under
17579 this mode we currently inherit the dispatch tables in the IP subprogram.
17580 (Write_DT): Emit an "is null" indication for a null procedure primitive.
17581 (Expand_Interface_Conversion): Use an address as the type of the formal
17582 of the internally built function that handles the case in which the

17633 we request a discriminal value only in case of discriminants.
17634 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
17635 assignments where the target subtype is unconstrained and the target
17636 object is a parameter or dereference (other aliased cases are known

17753 are build-in-place function calls.
17754 (Replace_Self_Reference): New subsidiary of
17755 Make_OK_Assignment_Statement, to replace an access attribute that is a
17756 self-reference into an access to the appropriate component of the
17757 target object. Generalizes previous mechanism to handle self-references
17758 nested at any level.
17759 (Is_Self_Referential_Init): Remove, not needed.

17766 default initialization.
17767 (Make_OK_Assignment_Statement): If the expression is of the form
17768 Typ'Acc, where Acc is an access attribute, the expression comes from a
17769 default initialized self-referential component.
17770 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
17771 that has been derived from several abstract interfaces we must also

17777 Robert Dewar <dewar@adacore.com>
17780 (Expand_Access_To_Protected_Op): If the context indicates that an access
17781 to a local operation may be transfered outside of the object, create an
17782 access to the wrapper operation that must be used in an external call.
17783 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
17784 target, pass the Valid attribute applied to a floating-point prefix on

17800 subcomponent's enclosing variable is aliased with a constrained subtype.
17801 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
17802 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
17803 an aliased prefix must be known to be constrained in order to use True
17804 for the attribute value, and now it's possible for some aliased views
17805 to be unconstrained.

17820 otherwise we incorrectly register the tag of the interface in the final
17822 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
17823 generate the wrapper if the parent primitive is abstract. This is
17824 required to report the correct error message.
17825 (Expand_N_Subtype_Indication): Do validity checks on range
17826 (Clean_Task_Names): If an initialization procedure includes a call to

17835 call to build-in-place function and apply Make_Build_In_Place_Call_In_
17836 Object_Declaration to the call.
17837 (Freeze_Type): When the designated type of an RACW was not frozen at the
17838 point where the RACW was declared, validate the primitive operations
17839 with respect to E.2.2(14) when it finally is frozen.
17840 (Build_Initialization_Call,Expand_Record_Controller): Rename
17841 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
17842 return-by-reference has no meaning in Ada 2005.

17844 to register tag of the immediate ancestor interfaces in the
17845 run-time structure.

17847 initialization of extension aggregates with abstract interfaces.
17848 (Build_Master_Renaming): Make public, for use by function declarations
17849 whose return type is an anonymous access type.
17850 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
17851 Insert_List_Before_And_Analyze after the generation of the specs
17852 associated with null procedures.

17854 (Init_Secondary_Tags): Update documentation.
17855 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
17856 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
17857 then generate code to inherit the contents of the dispatch table
17858 directly from the ancestor.
17859 (Expand_Record_Controller): Insert controller component after tags of
17860 implemented interfaces.
17861 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to

17865 declarations for overriding null primitives inherited from interfaces.
17866 (Is_Null_Interface_Procedure): New function in
17867 Make_Null_Procedure_Specs.
17868 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
17869 immediate ancestor of a tagged type is an abstract interface type we
17870 must generate the specification of the predefined primitives associated
17871 with controlled types (because the dispatch table of the ancestor is
17872 null and hence these entries cannot be inherited). This is required to
17873 elaborate well the dispatch table.

17887 the maximum for type T.
17888 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
17889 when the allocator is initialized by a build-in-place call, since the
17890 allocator is already rewritten as a reference to the function result,
17891 and this prevents an unwanted duplication of the function call.
17892 Add with and use of Exp_Ch6.
17893 (Expand_Allocator_Expresssion): Check for an allocator whose expression
17894 is a call to build-in-place function and apply
17895 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
17896 untagged designated types).
17897 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal

17917 in order to alleviate the upward compatibility introduced by AI-318.

17933 validity checking of assignments to elementary record components.
17934 (Expand_N_Return_Statement): return Class Wide types on the secondary
17935 stack independantly of their controlled status since with HIE runtimes,
17936 class wide types are not potentially controlled anymore.
17938 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
17941 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
17942 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
17943 it expects a block, procedure, or task. The return statement will get
17944 turned into a block, and Expand_Cleanup_Actions will happen then.

17948 Bob Duff <duff@adacore.com>
17949 Gary Dismukes <dismukes@adacore.com>
17951 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
17953 (Expand_Inlined_Call): Tagged types are by-reference types, and
17954 therefore should be replaced by a renaming declaration in the expanded
17955 body, as is done for limited types.
17956 (Expand_Call): If this is a call to a function with dispatching access
17957 result, propagate tag from context.
17958 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
17960 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
17961 build-in-place when the right-hand side of an assignment is a
17962 build-in-place function call.
17963 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
17964 of the explicit dereference of the allocator to the result subtype of
17965 the build-in-place function. This is needed to satisfy type checking
17966 in cases where the caller's return object is created by an allocator for
17967 a class-wide access type and the type named in the allocator is a
17969 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
17970 conversion of the reference to the declared object to the result subtype
17971 of the build-in-place function. This is needed to satisfy type checking
17972 in cases where the declared object has a class-wide type. Also, in the
17973 class-wide case, change the type of the object entity to the specific
17974 result subtype of the function, to avoid passing a class-wide object
17975 without explicit initialization to the back end.
17976 (Register_Interface_DT_Entry): Moved outside the body of
17977 Freeze_Subprogram because this routine is now public; it is called from
17978 Check_Dispatching_Overriding to handle late overriding of abstract
17979 interface primitives.
17980 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
17981 adding an implicit access actual on a call to a build-in-place function.
17982 (Expand_Actuals): Test for an actual parameter that is a call to a
17983 build-in-place function and apply
17984 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
17985 (Is_Build_In_Place_Function): New function to determine whether an
17986 entity is a function whose calls should be handled as build-in-place.
17987 (Is_Build_In_Place_Function_Call): New function to determine whether an
17988 expression is a function call that should handled as build-in-place.
17989 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
17990 calls to build-in-place functions as the initialization of an allocator.
17991 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
17992 handling calls to build-in-place functions in contexts that do not
17993 involve init of a separate object (for example, actuals of subprogram
17995 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
17996 handling calls to build-in-place functions as the initialization of an
17997 object declaration.
17998 (Detect_Infinite_Recursion): Add explicit parameter Process to
17999 instantiation of Traverse_Body to avoid unreferenced warning.
18000 (Check_Overriding_Inherited_Interfaces): Removed.
18001 (Register_Interface_DT_Entry): Code cleanup.
18002 (Register_Predefined_DT_Entry): Code cleanup.
18003 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
18004 inlined statements if within a transient scope.
18005 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
18006 formal parameters with occurrences of actuals in inlined body, establish
18007 visibility on the proper view of the actual's subtype for the body's
18009 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
18010 compatibility mode and we have an imported CPP subprogram because
18011 for now we assume that imported CPP primitives correspond with
18012 objects whose constructor is in the CPP side (and therefore we
18013 don't need to generate code to register them in the dispatch table).
18014 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
18015 aligned selected component.
18016 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
18017 the actual of an in-mode parameter is a type conversion.
18018 (Expand_Actuals): If the call does not come from source and the actual
18019 is potentially misaligned, let gigi handle it rather than rejecting the
18020 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
18021 Class Wide types as returning by reference independantly of their
18022 controlled status since with HIE runtimes class wide types are not
18023 potentially controlled anymore.
18025 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18027 * exp_ch9.adb (Update_Prival_Types): Simplify code for entity
18028 references that are private components of the protected object.
18029 (Build_Barrier_Function): Set flag Is_Entry_Barrier_Function
18030 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
18031 instantiation to deal with warnings.
18032 (Initialize_Protection): If expression for priority is non-static, use
18033 System_Priority as its expected type, in case the expression has not
18036 2006-10-31 Robert Dewar <dewar@adacore.com>
18038 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
18039 initialization of Homonym_Len.
18040 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
18041 names from fully qualified name. Fixes problem of duplicate
18042 external names differing only in the presence of such a block name.
18044 2006-10-31 Thomas Quinot <quinot@adacore.com>
18045 Pablo Oliveira <oliveira@adacore.com>
18047 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
18048 subprogram Ids, even if they are not yet assigned.
18049 (Build_Subprogram_Id): It is now this function that will take care of
18050 calling Assign_Subprogram_Ids if necessary.
18051 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
18052 should be done only once they are assigned.
18053 (Build_From_Any_Function, case of tagged types): Add missing call to
18055 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
18056 type for an RACW type.
18057 (Add_RACW_Features): When processing an RACW declaration for which the
18058 designated type is already frozen, enforce E.2.2(14) rules immediately.
18059 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
18060 special reordering of controlling formals.
18062 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
18063 associated stub type for an RACW type.
18065 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18067 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
18068 fixed-point operations in an integer context, i.e. as operands of a
18069 conversion to an integer type, indicate that result must be rounded.
18071 2006-10-31 Robert Dewar <dewar@adacore.com>
18073 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
18074 cases, pass the encoding method, since it is now required by the run
18077 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
18078 assumption that Str'First = 1.
18079 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
18080 it on to the Value_Wide_Wide_Character call.
18081 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
18082 properly handles a string of the form quote-encoded_wide_char-quote.
18084 * s-wchcnv.adb: Minor reformatting
18086 2006-10-31 Javier Miranda <miranda@adacore.com>
18088 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
18089 run-time membership test to ensure that the constructed object
18090 implements the target abstract interface.
18092 2006-10-31 Robert Dewar <dewar@adacore.com>
18094 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
18095 Machine_Attribute pragma internally to implement the user pragma.
18096 Add processing for pragma Interface so that it is now completely
18097 equivalent to pragma Import.
18099 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
18100 so that it can be applied to all entities, including record components
18101 and enumeration literals.
18102 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
18103 priority ranges are correct, verify compatibility against task
18104 dispatching and locking policies, and if everything is correct an entry
18105 is added to the table containing priority specific dispatching entries
18106 for this compilation unit.
18107 (Delay_Config_Pragma_Analyze): Delay processing
18108 Priority_Specific_Dispatching pragmas because when processing the
18109 pragma we need to access run-time data, such as the range of
18110 System.Any_Priority.
18111 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
18112 Allow pragma Unreferenced as a context item
18113 Add pragma Preelaborable_Initialization
18114 (Analyze_Pragma, case Interface): Interface is extended so that it is
18115 now syntactically and semantically equivalent to Import.
18116 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
18117 insertion characters.
18118 Add handling for Pragma_Wide_Character_Encoding
18119 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
18120 never supercedes a real restriction, and that a real restriction
18121 always supercedes a warning.
18122 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

18126 Ed Schonberg <schonberg@adacore.com>
18127 Robert Dewar <dewar@adacore.com>
18129 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
18130 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
18131 Is_Inherently_Limited_Type, because return-by-reference has no meaning
18133 (Find_Node_To_Be_Wrapped): Use new method of determining the result
18134 type of the function containing a return statement, because the
18135 Return_Type field was removed. We now use the Return_Applies_To field.
18137 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
18138 (Build_Task_Image_Decl): If procedure is not called from an
18139 initialization procedure, indicate that function that builds task name
18140 uses the sec. stack. Otherwise the enclosing initialization procedure
18141 will carry the indication.
18142 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
18143 N_Object_Declaration instead.
18144 (Kill_Dead_Code): New interface to implement -gnatwt warning for
18145 conditional dead code killed, and change implementation accordingly.
18146 (Insert_Actions): Add N_Return_Object_Declaration case.
18147 Correct comment to mention N_Extension_Aggregate node.
18148 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
18149 attempts to save information for global variables which cannot be
18151 (Get_Current_Value_Condition): Handle conditions the other way round
18152 (constant on left). Also handle right operand of AND and AND THEN
18153 (Set_Current_Value_Condition): Corresponding changes
18154 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
18155 (Get_Current_Value_Condition): Handle simple boolean operands
18156 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
18157 (Get_Current_Value_Condition): If the variable reference is within an
18158 if-statement, does not appear in the list of then_statments, and does
18159 not come from source, treat it as being at unknown location.
18160 (Get_Current_Value_Condition): Enhance to allow while statements to be
18161 processed as well as if statements.
18162 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
18164 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
18165 of loop. This is safe now that we fixed Kill_Current_Values.
18166 (OK_To_Do_Constant_Replacement): Check whether current scope is
18167 Standard, before examining outer scopes.
18169 2006-10-31 Vincent Celier <celier@adacore.com>
18171 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
18172 When True, apply VMS treatment to children of packages A, G, I and S.
18175 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
18177 2006-10-31 Robert Dewar <dewar@adacore.com>

18181 (Warn_Overlay): Supply missing continuation marks in error msgs
18182 (Freeze_Entity): Add check for Preelaborable_Initialization
18184 * g-comlin.adb: Add Warnings (Off) to prevent new warning
18186 * g-expect.adb: Add Warnings (Off) to prevent new warning
18188 * lib-xref.adb: Add handling of Last_Assignment field
18189 (Generate_Reference): Centralize handling of pragma Obsolescent here
18190 (Generate_Reference): Accept an implicit reference generated for a
18191 default in an instance.
18192 (Generate_Reference): Accept a reference for a node that is not in the
18193 main unit, if it is the generic body corresponding to an subprogram
18196 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
18198 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
18200 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
18202 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
18203 use clauses, to avoid messages on packages used to qualify, and also
18204 to avoid messages from obsolescent units.
18205 (Warn_On_Useless_Assignments): Don't generate messages for imported
18206 and exported variables.
18207 (Warn_On_Useless_Assignments): New procedure
18208 (Output_Obsolescent_Entity_Warnings): New procedure
18209 (Check_Code_Statement): New procedure
18211 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag
18212 Change name Is_Ada_2005 to Is_Ada_2005_Only
18213 (Last_Assignment): New field for useless assignment warning
18215 2006-10-31 Olivier Hainque <hainque@adacore.com>
18217 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
18218 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
18220 2006-10-31 Bob Duff <duff@adacore.com>
18221 Robert Dewar <dewar@adacore.com>
18222 Ed Schonberg <schonberg@adacore.com>
18224 * g-awk.adb (Default_Session, Current_Session): Compile this file in
18225 Ada 95 mode, because it violates the new rules for AI-318.
18227 * g-awk.ads: Use overloaded subprograms in every case where we used to
18228 have a default of Current_Session. This makes the code closer to be
18229 correct for both Ada 95 and 2005.
18231 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
18232 code, relying on the fact that the compiler generates a warning
18233 instead of an error in -gnatg mode.
18235 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
18236 E_Return_Statement entity kind.
18237 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
18239 * par.adb (P_Interface_Type_Definition): Addition of one formal to
18240 report an error if the reserved word abstract has been previously found.
18241 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
18243 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
18244 parenthesized range attribute usage
18245 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
18247 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
18248 in the syntax for extended_return_statement. This is not in the latest
18249 RM, but the ARG is expected to issue an AI allowing this.
18250 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
18251 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
18252 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
18253 P_Return_Statement): Parse the new syntax for extended_return_statement.
18255 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
18256 Output_End_Missing): Add error-recovery code for the new
18257 extended_return_statement syntax; that is, the new E_Return entry on
18260 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
18261 limited to nonlimited, because otherwise we violate the new Ada 2005
18262 rules about returning limited types in function Create_AST_Handler in
18265 * sem.adb (Analyze): Add cases for new node kinds
18266 N_Extended_Return_Statement and N_Return_Object_Declaration.
18268 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
18269 type is in the same category as type of context before applying check,
18270 to prevent anomalies in instantiations.
18271 (Resolve_Aggregate): Remove test for limited components in aggregates.
18272 It's unnecessary in Ada 95, because if it has limited components, then
18273 it must be limited. It's wrong in Ada 2005, because limited aggregates
18275 (Resolve_Record_Aggregate): Move check for limited types later, because
18276 OK_For_Limited_Init requires its argument to have been resolved.
18277 (Get_Value): When copying the component default expression for a
18278 defaulted association in an aggregate, use the sloc of the aggregate
18279 and not that of the original expression, to prevent spurious
18280 elaboration errors, when the expression includes function calls.
18281 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
18282 were missing. We also didn't handle qualified expressions. Now also
18283 allow function calls. Use new common routine OK_For_Limited_Init.
18284 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
18285 with space can upper case letter).
18287 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
18288 Has_Static_Discriminants flag
18289 (Record_Type_Declaration): Diagnose an attempt to declare an interface
18290 type with discriminants.
18291 (Process_Range_Expr_In_Decl): Do validity checks on range
18292 (Build_Discriminant_Constraints): Use updated form of
18293 Denotes_Discriminant.
18294 (Process_Subtype): If the subtype is a private subtype whose full view
18295 is a concurrent subtype, introduce an itype reference to prevent scope
18297 (Build_Derived_Record_Type, Collect_Interface_Primitives,
18298 Record_Type_Declaration): The functionality of the subprograms
18299 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
18300 is now performed by a single routine.
18301 (Build_Derived_Record_Type): If the type definition includes an explicit
18302 indication of limitedness, then the type must be marked as limited here
18303 to ensure that any access discriminants will not be treated as having
18304 a local anonymous access type.
18305 (Check_Abstract_Overriding): Issue a detailed error message when an
18306 abstract subprogram was not overridden due to incorrect mode of its
18308 (Analyze_Private_Extension_Declaration): Add support for the analysis of
18309 synchronized private extension declarations. Verify that the ancestor is
18310 a limited or synchronized interface or in the generic case, the ancestor
18311 is a tagged limited type or synchronized interface and all progenitors
18312 are either limited or synchronized interfaces.
18313 Derived_Type_Declaration): Check for presence of private extension when
18314 dealing with synchronized formal derived types.
18315 Process_Full_View): Enchance the check done on the usage of "limited" by
18316 testing whether the private view is synchronized.
18317 Verify that a synchronized private view is completed by a protected or
18319 (OK_For_Limited_Init_In_05): New function.
18320 (Analyze_Object_Declaration): Move check for limited types later,
18321 because OK_For_Limited_Init requires its argument to have been resolved.
18322 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
18323 in order to alleviate the upward compatibility introduced by AI-318.
18324 (Constrain_Corresponding_Record): If the constraint is for a component
18325 subtype, mark the itype as frozen, to avoid out-of-scope references to
18326 discriminants in the back-end.
18327 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
18328 this subprogram against wrong sources.
18329 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
18330 discriminant of limited type completed with a protected type, when the
18331 discriminant is used to constrain a private component of the type, and
18332 expansion is disabled.
18333 (Find_Type_Of_Object): Do not treat a return subtype that is an
18334 anonymous subtype as a local_anonymous_type, because its accessibility
18335 level is the return type of the enclosing function.
18336 (Check_Initialization): In -gnatg mode, turn the error "cannot
18337 initialize entities of limited type" into a warning.
18338 (OK_For_Limited_Init): Return true for generated nodes, since it
18339 sometimes violates the legality rules.
18340 (Make_Incomplete_Declaration): If the type for which an incomplete
18341 declaration is created happens to be the currently visible entity,
18342 preserve the homonym chain when removing it from visibility.
18343 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
18344 inherited subprograms.
18345 (Access_Definition): If this is an access to function that is the return
18346 type of an access_to_function definition, context is a type declaration
18347 and the scope of the anonymous type is the current one.
18348 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
18349 incomplete subtype to the set of private dependents of the original
18351 (Constrain_Discriminated_Type): Emit an error message whenever an
18352 incomplete subtype is being constrained.
18353 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
18354 corresponding subtype of the full view of the original incomplete type.
18355 (Check_Incomplete): Properly detect invalid usage of incomplete types
18358 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
18360 * g-catiio.ads, g-catiio.adb (Value): New function.
18361 Given an input String, try and parse a valid Time value.
18363 2006-10-31 Vincent Celier <celier@adacore.com>
18365 * g-debpoo.adb (Is_Valid): Correctly compute Offset using
18366 Integer_Address arithmetic, as in Set_Valid.

18369 Robert Dewar <dewar@adacore.com>
18371 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
18372 handling executable extension manually and duplicating code.
18374 * make.adb: Implement new -S switch
18375 (Gnatmake): Use new function Osint.Executable_Name instead
18376 of handling executable extension manually.
18378 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
18379 is specified, the executable name ends with this suffix.
18380 Take advantage of Osint.Executable_Name instead of duplicating code.
18382 * switch-m.adb: Recognize new gnatmake -S switch
18384 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
18386 (Get_Target_Parameters): Set Executable_Extension_On_Target if
18389 * makeusg.adb: Add line for gnatmake -S switch
18391 2006-10-31 Vincent Celier <celier@adacore.com>
18393 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
18394 call it with -static-libgcc, as there are some platforms, such as
18395 Darwin, where one of these two switches is compulsory to link.
18397 2006-10-31 Vincent Celier <celier@adacore.com>
18399 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
18400 instead of ADA_PROJECT_PATH, for the project path.
18401 (Gnatls): When displaying the project path directories, use host dir
18404 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
18405 names in the project path, as absolute paths may correspond to
18406 multi-valued VMS logical names.
18408 2006-10-31 Vincent Celier <celier@adacore.com>
18410 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
18411 absolute path name.
18412 (Locate_Regular_File): Ditto
18413 (Change_Dir): Remove, no longer used
18414 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
18415 on Windows. Get it calling Get_Current_Dir.

18428 2006-10-31 Robert Dewar <dewar@adacore.com>
18430 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
18431 initial letter o as a zero.

18435 * g-spipat.adb (S_To_PE): Remove incorrect use of 0 instead of Str'First
18437 2006-10-31 Robert Dewar <dewar@adacore.com>
18439 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
18441 (Layout_Variant_Record): Retrieve the discriminants from the entity
18442 rather than from the type definition, because in the case of a full
18443 type for a private type we need to take the discriminants from the
18445 (Layout_Component_List): When applying the Max operator to variants with
18446 a nonstatic size, check whether either operand is static and scale that
18447 operand from bits to storage units before applying Max.
18448 (Layout_Type): In VMS, if a C-convention access type has no explicit
18449 size clause (and does not inherit one in the case of a derived type),
18450 then the size is reset to 32 from 64.
18452 2006-10-31 Vincent Celier <celier@adacore.com>
18454 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
18455 its file has already been loaded, according to the unit being loaded,
18456 not to the current value of Multiple_Unit_Index.
18458 2006-10-31 Thomas Quinot <quinot@adacore.com>
18459 Eric Botcazou <ebotcazou@adacore.com>
18460 Arnaud Charlet <charlet@adacore.com>
18462 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
18463 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
18465 (a-except.o): Pass it to the compiler.
18466 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
18467 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
18468 a-calend-mingw.adb version.

18473 Ada.Dispatching.Round_Robin.
18474 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
18476 * Make-lang.in: Remove all references to gt-ada-decl.h.
18477 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
18479 Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
18480 Update dependencies.
18482 * system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
18484 2006-10-31 Vincent Celier <celier@adacore.com>
18486 * mlib-utl.adb (Initialized): Remove, no longer used
18487 (Initialize): Remove, no longer used
18488 (Ar): If Ar_Exec is null, get the location of the archive builder and,
18489 if there is one, the archive indexer. Fail if the archive builder cannot
18491 (Gcc): If the driver path is unknown, get it. Fail if the driver cannot
18494 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18496 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
18497 Process_Body_Clauses): If the context of a body includes a use clause
18498 for P.Q then a with_clause for P in the same body is not redundant,
18499 even if the spec also has a with_clause on P.
18500 Add missing continuation mark to error msg
18501 (Build_Limited_Views): A limited view of a type is tagged if its
18502 declaration includes a record extension.
18503 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
18504 node, even if the subunit has errors. This avoids malfunction by
18505 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
18506 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
18507 generation of obsolescent messages for with statements (cannot do
18508 this too early, or we cannot implement avoiding the messages in the
18509 case of obsolescent units withing obsolescent units).
18510 (Install_Siblings): If the with_clause is on a remote descendant of
18511 an ancestor of the current compilation unit, find whether there is
18512 a sibling child unit that is immediately visible.
18513 (Remove_Private_With_Clauses): New procedure, invoked after completing
18514 the analysis of the private part of a nested package, to remove from
18515 visibility the private with_clauses of the enclosing package
18517 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
18518 now centralized in Generate_Reference.
18519 (Install_Limited_Context_Clauses): Remove superfluous error
18520 message associated with unlimited view visible through use
18521 and renamings. In addition, at the point in which the error
18522 is reported, we add the backslash to the text of the error
18523 to ensure that it is reported as a single error message.
18524 Use new // insertion for some continuation messages
18525 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
18526 to create implicit with_clause for parent unit mentioned in original
18527 limited_with_clause.
18528 (Install_Limited_With_Unit): Set entity of parent identifiers if the
18529 unit is a child unit. For ASIS queries.
18530 (Analyze_Subunit): If the subunit appears within a child unit, make all
18531 ancestor child units directly visible again.

18543 Add the new actual Abstract_Present to every call to
18544 P_Interface_Type_Definition.
18545 (P_Formal_Object_Declarations): Update grammar rules. Handle parsing of
18546 a formal object declaration with an access definition or a subtype mark
18547 with a null exclusion.
18548 (P_Generic_Association): Handle association with box, and others_choice
18549 with box, to support Ada 2005 partially parametrized formal packages.
18551 2006-10-31 Robert Dewar <dewar@adacore.com>
18552 Javier Miranda <miranda@adacore.com>
18554 * par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
18555 (P_Type_Declaration): Remove barrier against the reserved word "limited"
18556 after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
18557 (P_Type_Declaration): Minor code cleanup. Add support for synchronized
18558 private extensions.
18559 (P_Type_Declaration): Add the new actual Abstract_Present to every call
18560 to P_Interface_Type_Definition.
18561 (P_Interface_Type_Definition): Addition of one formal to report an error
18562 if the reserved word abstract has been previously found.
18563 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
18564 object renaming declaration with an access definition or subtype mark
18565 with a possible null exclusion.
18567 * par-ch9.adb: Minor error msg fix
18569 * par-load.adb: Add missing continuation mark to error msg
18571 * par-tchk.adb: (Wrong_Token): Code cleanup, use concatenation

18576 unknown attribute in unknown package or in package that does not need
18578 (Parse_Package_Declaration): Do not issue warning for unknown package in
18581 2006-10-31 Vincent Celier <celier@adacore.com>
18583 * prj-makr.adb (Packages_To_Check_By_Gnatname): New global constant
18584 (Make): Call Parse with Packages_To_Check_By_Gnatname for parameter
18587 2006-10-31 Vincent Celier <celier@adacore.com>
18589 * prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
18590 on VMS, change "__" to '.' before checking the name.
18591 (Record_Ada_Source): Always add the source file name in the list of
18592 of sources, even if it is not the first time, as it is for another
18594 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
18595 dot, instead of replacing only the first '_'.
18597 * prj-part.adb (Parse): Convert project file path to canonical form
18599 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
18600 extended, the project id of the project extending it is recorded in its
18601 data, even when it has already been processed as an imported project.
18603 2006-10-31 Robert Dewar <dewar@adacore.com>
18605 * repinfo.adb (List_Entities): Don't list entities from renaming
18608 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18609 Robert Dewar <dewar@adacore.com>
18611 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
18612 only a restriction warning is active for the given restriction. This is
18613 desirable because we do not want to modify code in the case where only
18615 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
18616 causes overriding of real restrictions.
18617 Take advantage of new No_Restrictions constant.
18619 * raise.h: (__gnat_set_globals): Change profile.
18621 2006-10-31 Arnaud Charlet <charlet@adacore.com>
18623 * rtsfind.adb: Remove s-polint from comment as it exists no more.
18626 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.
18627 Move all the entities in obsolete package System.PolyORB_Interface to
18628 System.Partition_Interface.
18629 (RE_Storage_Size): New function in System.Tasking.

18642 Thomas Quinot <quinot@adacore.com>
18643 Javier Miranda <miranda@adacore.com>
18644 Gary Dismukes <dismukes@adacore.com>
18646 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
18647 properly an attempt to apply Unchecked_Access to a protected operation.
18648 (OK_Self_Reference): New subprogram to check the legality of an access
18649 attribute whose prefix is the type of an enclosing aggregate.
18650 Generalizes previous mechanism to handle attribute references nested
18651 arbitrarily deep within the aggregate.
18652 (Analyze_Access_Attribute): An access attribute whose prefix is a type
18653 can appear in an aggregate if this is a default-initialized aggregate
18654 for a self-referential type.
18655 (Resolve_Attribute, case Access): Ditto.
18656 Add support for new implementation defined attribute Stub_Type.
18657 (Eval_Attribute, case Attribute_Stub_Type): New case.
18658 (Analyze_Attribute, case Attribute_Stub_Type): New case.
18659 (Stream_Attribute_Available): Implement using new subprogram from
18660 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
18661 Has_Specified_Stream_Attribute flag.
18662 Disallow Storage_Size and Storage_Pool for access to subprogram
18663 (Resolve_Attribute, case 'Access et al): Take into account anonymous
18664 access types of return subtypes in extended return statements. Remove
18665 accessibility checks on anonymous access types when Unchecked_Access is
18667 (Analyze_Attribute): Add support for the use of 'Class to convert
18668 a class-wide interface to a tagged type.
18669 Add support for the attribute Priority.
18670 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
18671 whether the designated type is discriminated with a constrained partial
18672 view and require static matching in that case.
18673 Add local variable Des_Btyp. The Designated_Type
18674 of an access to incomplete subtype is either its non-limited view if
18675 coming from a limited with or its etype if regular incomplete subtype.
18677 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
18678 Fix predicate to identify and allow cases of (expander-generated)
18679 references to tag of designated object of a RACW.
18680 (Validate_Static_Object_Name): In Ada 2005, a formal object is
18681 non-static, and therefore cannot appear as a primary in a preelaborable
18683 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
18684 Has_Read_Write_Attributes.
18685 (Has_Read_Write_Attributes): Reimplement in termes of
18686 Has_Stream_Attribute_Definition.
18687 (Missing_Read_Write_Attributes): When checking component types in a
18688 record, unconditionally call Missing_Read_Write_Attributes recursively
18689 (remove guard checking for Is_Record_Type / Is_Access_Type).
18691 2006-10-31 Robert Dewar <dewar@adacore.com>
18693 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
18694 useless assignments here and conditionalize it on absence of exception
18696 (Analyze_Exception_Handlers): Small code reorganization of error
18697 detection code, for new handling of formal packages.
18699 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18700 Hristian Kirtchev <kirtchev@adacore.com>
18702 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
18703 that has been constant-folded, preserve information of original tree,
18705 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
18706 generated private extension declaration if the formal derived type is
18707 synchronized. Carry synchronized present over to the generated private
18709 (Validate_Derived_Type_Instance): Ensure that the actual of a
18710 synchronized formal derived type is a synchronized tagged type.
18711 (Instantiate_Formal_Package): When creating the instantiation used to
18712 validate the actual package of a formal declared without a box, check
18713 whether the formal itself depends on a prior actual.
18714 (Instantiate_Formal_Subprogram): Create new entities for the defining
18715 identifiers of the formals in the renaming declaration, for ASIS use.
18716 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
18717 a renaming declaration or a subtype declaration for an actual in an
18718 instance, capture location information of declaration in generic, for
18720 (Instantiate_Formal_Package): Add comments on needed additional tests.
18721 AI-317 (partial parametrization) is fully implemented.
18722 (Validate_Private_Type_Instance): Add check for actual which
18723 must have preelaborable initialization
18724 Use new // insertion for some continuation messages
18725 (Analyze_Formal_Object_Declaration): Change usage of Expression to
18726 Default_Expression. Add type retrieval when the declaration has an
18727 access definition. Update premature usage of incomplete type check.
18728 (Check_Access_Definition): New subsidiary routine. Check whether the
18729 current compilation version is Ada 05 and the supplied node has an
18731 (Instantiate object): Alphabetize local variables. Handle the creation
18732 of new renaming declarations with respect to the kind of definition
18733 used - either an access definition or a subtype mark. Guard against
18734 unnecessary error message in the context of anonymous access types after
18735 they have been resolved. Add check for required null exclusion in a
18736 formal object declaration.
18737 (Switch_View): A private subtype of a non-private type needs to be
18738 switched (the base type can have been switched without its private
18739 dependents because of the last branch of Check_Private_View.
18740 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
18742 (Instantiate_Type): Emit an error message whenever a class-wide type of
18743 a tagged incomplete type is used as a generic actual.
18744 (Find_Actual_Type): Extend routine to handle a component type in a child
18745 unit that is imported from a formal package in a parent.
18746 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
18747 agree on constrainedness, rather than checking against ultimate ancestor
18748 (Instantiate_Subprogram_Body): Create a cross-reference link to the
18749 generic body, for navigation purposes.
18751 2006-10-31 Robert Dewar <dewar@adacore.com>
18752 Thomas Quinot <quinot@adacore.com>
18754 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
18756 (New_Stream_Subprogram): When processing an attribute definition clause
18757 for a stream-oriented subprogram, record an entity node occurring at
18758 the point of clause to use for checking the visibility of the clause,
18759 as defined by 8.3(23) as amended by AI-195.
18760 (New_Stream_Subprogram): New procedure, factoring behaviour from both
18761 New_Stream_Function and New_Stream_Procedure.
18762 (New_Stream_Function, New_Stream_Procedure): Removed.
18763 (Analyze_Attribute_Definition_Clause, case Address): Check new
18764 Alignment_Check check

18767 Javier Miranda <miranda@adacore.com>
18768 Robert Dewar <dewar@adacore.com>
18770 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
18771 generate the same errors compiling under -gnatc.
18772 (Try_Object_Operation): If no candidate interpretation succeeds, but
18773 there is at least one primitive operation with the right name, report
18774 error in call rather than on a malformed selected component.
18775 (Analyze_Selected_Component): If the prefix is an incomplete type from
18776 a limited view, and the full view is available, use the full view to
18777 determine whether this is a prefixed call to a primitive operation.
18778 (Operator_Check): Verify that a candidate interpretation is a binary
18779 operation before checking the type of its second formal.
18780 (Analyze_Call): Add additional warnings for function call contexts not
18782 (Analyze_Allocator): Move the check for "initialization not allowed for
18783 limited types" after analyzing the expression. This is necessary,
18784 because OK_For_Limited_Init looks at the structure of the expression.
18785 Before analysis, we don't necessarily know what sort of expression it
18786 is. For example, we don't know whether F(X) is a function call or an
18787 indexed component; the former is legal in Ada 2005; the latter is not.
18788 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
18789 were missing. We also didn't handle qualified expressions. Now also
18790 allow function calls. Use new common routine OK_For_Limited_Init.
18791 (Analyze_Type_Conversion): Do not perform some legality checks in an
18792 instance, because the error message will be redundant or spurious.
18793 (Analyze_Overloaded_Selected_Component): Do not do style check when
18794 setting an entity, since we do not know it is the right entity yet.
18795 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
18796 (Analyze_Overloaded_Selected_Component): Same change
18797 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
18798 since regular incomplete subtypes are transformed into corresponding
18799 subtypes of their full views.
18800 (Complete_Object_Operation): Treat name of transformed subprogram call
18801 as coming from source, for browsing purposes.
18802 (Try_Primitive_Operation): If formal is an access parameter, compare
18803 with base type of object to determine whether it is a primitive
18805 (Operator_Check): If no interpretation of the operator matches, check
18806 whether a use clause on any candidate might make the operation legal.
18807 (Try_Class_Wide_Operation): Check whether the first parameter is an
18808 access type whose designated type is class-wide.

18815 warn on infinite loops.
18816 Add \\ to some continuation messages
18817 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
18818 (Process_Bounds): If the bounds are integer literals that result from
18819 constant-folding, and they carry a user-defined type, preserve that type
18820 rather than treating this as an integer range.
18821 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
18822 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
18823 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
18824 left hand side of assignment.
18825 (Analyze_Assignment): Add suport to manage assigments to the attribute
18826 priority of a protected object.
18827 (Check_Possible_Current_Value_Condition): Allow fully qualified names
18828 not just identifiers.
18829 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
18830 or AND THEN for possible tracking.
18831 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
18832 case of while loops so we can track values in the loop body.
18834 2006-10-31 Ed Schonberg <schonberg@adacore.com>
18835 Hristian Kirtchev <kirtchev@adacore.com>
18836 Bob Duff <duff@adacore.com>
18838 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
18839 procedure cannot be a protected operation (it is a basic_declaration,
18840 not a subprogram_declaration).
18841 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
18842 Subp. Add logic for entry processing.
18843 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
18844 Determine whether an entry or subprogram of a protected or task type
18845 override an inherited primitive of an implemented interface.

18847 Update the actual used in calls to Check_Overriding_Indicator.

18855 Extra_Formals field.
18856 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
18857 pass new parameters. Add support for adding the new extra access formal
18858 for functions whose calls are treated as build-in-place.
18859 (Analyze_A_Return_Statement): Correct casing in error message.
18860 Move Pop_Scope to after Analyze_Function_Return, because an extended
18861 return statement really is a full-fledged scope. Otherwise, visibility
18862 doesn't work right. Correct use of "\" for continuation messages.
18863 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
18864 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
18865 the node doesn't get properly marked as analyzed.
18866 (Analyze_Subprogram_Body): If subprogram is a function that returns
18867 an anonymous access type that denotes a task, build a Master Entity
18869 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
18870 proper usage of null exclusion in a result definition.

18878 (New_Overloaded_Entity): Do not remove the overriden entity from the
18879 homonym chain if it corresponds with an abstract interface primitive.
18880 (Process_Formals): Replace membership test agains Incomplete_Kind with a
18881 call to the synthesized predicate Is_Incomplete_Type.
18882 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
18884 (Analyze_Subprogram_Declaration): Check that abstract interface
18885 primitives are abstract or null.
18886 (Analyze_Subprogram_Specification): Remove previous check for abstract
18887 interfaces because it was not complete.
18888 (Has_Interface_Formals): Removed.

18898 package, install private_with_clauses of enclosing compilation unit if
18899 we are in its visible part.
18900 (Declare_Inherited_Private_Subprograms): Complete barrier
18901 to ensure that the primitive operation has an alias to some parent
18902 primitive. This is now required because, after the changes done for the
18903 implementation of abstract interfaces, the contents of the list of
18904 primitives has entities whose alias attribute references entities of
18905 such list of primitives.
18906 (Analyze_Package_Specification): Simplify code that handles parent units
18907 of instances and formal packages.
18908 (Uninstall_Declarations): Check the convention consistency among
18909 primitive overriding operations of a tagged record type.

18923 as potentially use-visible.
18924 (Find_Type): Handle the case of an attribute reference for
18925 implementation defined attribute Stub_Type (simply let the analysis of
18926 the attribute reference rewrite it).

18934 (Analyze_Object_Renaming): Introduce checks for required null exclusion
18935 in a formal object declaration or in a subtype declaration.
18936 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
18937 (Check_Null_Exclusion): New local routine to
18938 Analyze_Subprogram_Renaming. Check whether the formals and return
18939 profile of a renamed subprogram have required null exclusions when
18940 their counterparts of the renaming already impose them.
18941 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
18942 Determine whether an entity is inside a generic scope.
18943 (In_Open_Scope): First pass of documentation update.
18944 (Find_Expanded_Name): Add support for shadow entities associated with
18945 limited withed packages. This is required to handle nested packages.
18946 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217
18947 that makes a renaming of a limited withed package illegal.

18950 Ed Schonberg <schonberg@adacore.com>
18952 * sem_ch9.adb (Analyze_Protected_Definition): Remove call to
18953 Check_Overriding_Indicator.
18954 (Analyze_Task_Definition): Ditto.
18955 (Analyze_Protected_Type, Analyze_Task_Type): Code cleanup.
18956 (Check_Overriding_Indicator): To find overridden interface operation,
18957 examine only homonyms that have an explicit subprogram declaration, not
18958 inherited operations created by an unrelated type derivation.
18959 (Check_Overriding_Indicator): When checking for the presence of "null"
18960 in a procedure, ensure that the queried node is a procedure
18962 (Matches_Prefixed_View_Profile): Add mechanism to retrieve the parameter
18963 type when the formal is an access to variable.
18964 (Analyze_Protected_Type): Add check for Preelaborable_Initialization
18965 (Analyze_Task_Type): Same addition
18966 (Analyze_Entry_Declaration): Call Generate_Reference_To_Formals, to
18967 provide navigation capabilities for entries.

18974 * sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
18975 inherited from an interface ancestor by another interface in the
18976 context of an instance as 'late'.

18978 of a call to a function that dispatches on access result.
18979 (Check_Dispatching_Operation): In case of late overriding of a primitive
18980 that covers abstract interface subprograms we register it in all the
18981 secondary dispatch tables associated with abstract interfaces.
18982 (Check_Dispatching_Call): Add check that a dispatching call is not made
18983 to a function with a controlling result of a limited type. This is a
18984 current implementation restriction.
18985 (Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
18986 (Check_Dispatching_Operation): Do no emit a warning if the controlling
18987 argument is an interface type that is a generic formal.
18988 (Is_Interface_Subprogram): Removed.
18989 (Check_Dispatching_Operation): If the subprogram is not a dispatching
18990 operation, check the formals to handle the case in which it is
18991 associated with an abstract interface type.

19009 Javier Miranda <miranda@adacore.com>
19011 * sem_type.adb (Add_One_Interp): If node is an indirect call, preserve
19012 subprogram type to provide better diagnostics in case of ambiguity.

19014 the context of generic instantiation.
19015 (Covers/Interface_Present_In_Ancestors): Use the base type to manage
19016 abstract interface types; this is required to handle concurrent types
19017 with discriminants and abstract interface types.

19031 Add missing continuation marks in error msgs
19032 (Unqualify): New function for removing zero or more levels of
19033 qualification from an expression. There are numerous places where this
19034 ought to be used, but we currently only deal properly with zero or one
19036 (In_Instance); The analysis of the actuals in the instantiation of a
19037 child unit is not within an instantiation, even though the parent
19038 instance is on the scope stack.

19041 (Check_Obsolescent): Removed
19042 (Is_Aliased_View): A reference to an enclosing instance in an aggregate

19060 (Has_Compatible_Alignment): New function
19061 (Is_Dependent_Component_Of_Mutable_Object): Revise the tests for mutable
19062 objects to handle the Ada 2005 case, where aliasedness no longer implies

19120 (N_Extended_Return_Statement): New node for extended_return_statement
19122 (N_Return_Object_Declaration): New node for part of

19297 This is a significant redesign primarily for the sake of automatic
19298 timer task termination but also to fix a design flaw.
19299 Therefore we are now using an RTS lock, instead of a protected
19300 object, to provide mutual exclusion to the queue of pending events
19301 and the type Timing_Event is no longer a protected type.

20149 other basic tools. The full version that includes the Ada 2005 stuff

20475 -d is now controlling the primary stack size when its value is a
20476 positive. Also add checks against invalid values, and support for kb,
20477 mb. Ditto for -D switch.
20479 2006-02-13 Robert Dewar <dewar@adacore.com>
20480 Serguei Rybin <rybin@adacore.com>
20482 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
20483 save/restore routines.
20484 Properly handle Ada_Version_Explicit and Ada_Version_Config, which

20486 Since we are changing the tree format anyway, also get rid of the
20487 junk obsolete Immediate_Errors flag.
20488 (Tree_Read): Change the way of reading Tree_Version_String - now we
20489 read the version string from the tree even if its length is not the
20490 same as the length of the version string computed from Gnatvsn.

20522 whose ancestor has discriminants.
20524 * exp_ch2.adb: Update status of new Is_Known_Null flag
20526 * sem_ch7.adb: Maintain status of new Is_Known_Null flag

20553 are of equal length and have the same start and end values.
20554 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
20555 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
20556 aggregate when it is part of an object declaration.
20557 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
20558 constrains discriminants of its parent, add explicitly the discriminant
20559 constraints of the ancestor by retrieving them from the
20560 stored_constraint of the parent.
20562 2006-02-13 Robert Dewar <dewar@adacore.com>
20564 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
20565 attribute Mechanism_Code is applied to renamed subprogram, modify
20566 prefix to point to base subprogram.
20567 Max/Min attributes now violate Restriction No_Implicit_Conditionals
20569 * sinfo.ads: Document that Mechanism_Code cannot be applied to
20570 renamed subprograms so that the front-end must replace the prefix

20574 Gary Dismukes <dismukes@adacore.com>
20576 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
20577 availability of RE_Interface_Tag.
20578 (Build_Initialization_Call): Fix wrong access to the discriminant value.
20579 (Freeze_Record_Type): Do not generate the tables associated with
20580 timed and conditional dispatching calls through synchronized
20581 interfaces if compiling under No_Dispatching_Calls restriction.
20582 When compiling for Ada 2005, for a nonabstract
20583 type with a null extension, call Make_Controlling_Function_Wrappers
20584 and insert the wrapper function declarations and bodies (the latter
20585 being appended as freeze actions).
20586 (Predefined_Primitive_Bodies): Do not generate the bodies of the
20587 predefined primitives associated with timed and conditional
20588 dispatching calls through synchronized interfaces if we are
20589 compiling under No_Dispatching_Calls.
20590 (Build_Init_Procedure): Use RTE_Available to check if a run-time
20591 service is available before generating a call.
20592 (Make_Controlling_Function_Wrappers): New procedure.
20593 (Expand_N_Full_Type_Declaration): Create a class-wide master for
20594 access-to-limited-interfaces because they can be used to reference
20595 tasks that implement such limited interface.
20596 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
20597 procedure spec and body of the Offset_To_Top function that is generated
20598 when the parent of a type with discriminants has secondary dispatch
20600 (Init_Secondary_Tags): Handle the case in which the parent of the type
20601 containing secondary dispatch tables has discriminants to generate the
20602 correct arguments to call Set_Offset_To_Top.
20603 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
20605 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
20606 Add Wide_[Wide_]Expanded_Name.
20607 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
20608 the same functionality of Get_Prim_Op_Address but applied to predefined
20609 primitive operations because the pointers to the predefined primitives
20610 are now saved in a separate table.
20611 (Parent_Size): Modified to get access to the separate table of primitive
20612 operations or the parent type.
20613 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
20614 functionality of Set_Prim_Op_Address but applied to predefined primitive
20616 (Set_Signature): New subprogram used to store the signature of a DT.
20617 (Displace): If the Offset_To_Top value is not static then call the
20618 function generated by the expander to get such value; otherwise use
20619 the value stored in the table of interfaces.
20620 (Offset_To_Top): The type of the actual has been changed to Address to
20621 give the correct support to tagged types with discriminants. In this
20622 case this value is stored just immediately after the tag field.
20623 (Set_Offset_To_Top): Two new formals have been added to indicate if the
20624 offset_to_top value is static and hence pass this value to the run-time
20625 to store it in the table of interfaces, or else if this value is dynamic
20626 and then pass to the run-time the address of a function that is
20627 generated by the expander to provide this value for each object of the
20630 * rtsfind.ads (Default_Prin_Op_Count): Removed.
20631 (Default_Prim_Op_Count): New entity

20640 Make_Adjust_Call done for a newly-allocated object.
20642 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
20643 in a subprogram are wrapped in a cleanup block, indicate that the
20644 subprogram contains an inner block with an exception handler.
20645 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
20646 Adjust call is for a newly-allocated object. In that case we must not
20647 assume that the finalization list chain pointers are correct (since they
20648 come from a bit-for-bit copy of the original object's pointers) so if
20649 the attach level would otherwise be zero (no change), we set it to 4
20650 instead to cause the pointers to be reset to null.
20652 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
20653 reset chain pointers to null.
20655 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20657 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
20658 string, and the context requires a loop for the assignment (e.g.
20659 because the left-hand side is packed), generate a unique name for the
20660 temporary that holds the string, to prevent spurious name clashes.
20662 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20663 Javier Miranda <miranda@adacore.com>
20664 Robert Dewar <dewar@adacore.com>
20665 Gary Dismukes <dismukes@adacore.com>
20667 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
20668 return unconstrained arrays.
20670 (Expand_Call): An indirect call through an access parameter of a
20671 protected operation is not a protected call.
20672 Add circuit to raise CE in Ada 2005 mode following call
20673 to Raise_Exception.
20674 (Register_DT_Entry): Do nothing if
20675 the run-time does not give support to abstract interfaces.
20676 (Freeze_Subprogram): In case of dispatching operations, do not generate
20677 code to register the operation in the dispatch table if the source
20678 is compiled with No_Dispatching_Calls.
20679 (Register_Predefined_DT_Entry): Generate code that calls the new
20680 run-time subprogram Set_Predefined_Prim_Op_Address instead of
20681 Set_Prim_Op_Address.
20683 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
20684 on array assignments if the right-hand side is a function call that has
20685 been inlined. Check is performed on the assignment in the block.
20686 (Process_Bounds): If bounds and range are overloaded, apply preference
20687 rule for root operations to disambiguate, and diagnose true ambiguity.
20688 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
20689 a tag-indeterminate right-hand side even when Expander_Active is True.
20690 Needed to ensure that dispatching calls to T'Input are allowed and
20691 get the tag of the target class-wide object.
20693 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
20694 an inherited primitive operation that already overrides several
20695 abstract interface primitives. For transitivity, the new entity must
20696 also override all the abstract interface primitives covered by the
20697 inherited overriden primitive.
20698 Emit warning if new entity differs from homograph in same scope only in
20699 that one has an access parameter and the other one has a parameter of
20700 a general access type with the same designated type, at the same
20701 position in the signature.
20702 (Make_Inequality_Operator): Use source locations of parameters and
20703 subtype marks from corresponding equality operator when creating the
20704 tree structure for the implicit declaration of "/=". This does not
20705 change anything in behaviour except that the decoration of the
20706 components of the subtree created for "/=" allows ASIS to get the
20707 string images of the corresponding identifiers.
20708 (Analyze_Return_Statement): Remove '!' in warning message.
20709 (Check_Statement_Sequence): Likewise.
20710 (Analyze_Subprogram_Body): For an access parameter whose designated type
20711 is an incomplete type imported through a limited_with clause, use the
20712 type of the corresponding formal in the body.
20713 (Check_Returns): Implicit return in No_Return procedure now raises
20714 Program_Error with a compile time warning, instead of beging illegal.
20715 (Has_Single_Return): Function returning unconstrained type cannot be
20716 inlined if expression in unique return statement is not an identifier.
20717 (Build_Body_To_Inline): It is possible to inline a function call that
20718 returns an unconstrained type if all return statements in the function
20719 return the same local variable. Subsidiary procedure Has_Single_Return
20720 verifies that the body conforms to this restriction.
20722 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
20723 same type, and one of them is of an anonymous access type, convert
20724 the other operand to it, so that this is a valid binary operation for
20726 (Resolve_Type_Conversion): Handle subtypes of protected types and
20727 task types when accessing to the corresponding record type.
20728 (Resolve_Allocator): Add '\' in 2-line warning message.
20729 Remove '!' in warning message.
20730 (Resolve_Call): Add '\' in 2-line warning message.
20731 (Valid_Conversion): Likewise.
20732 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
20733 resulting type may be an access type with an implicit dereference.
20734 Obtain the proper component from the designated type.
20735 (Make_Call_Into_Operator): Handle properly a call to predefined equality
20736 given by an expanded name with prefix Standard, when the operands are
20737 of an anonymous access type.
20738 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
20739 Explicit_Dereference and Resolve_Selected_Component, to verify that the
20740 prefix of the expression is not of an incomplete type. Allows full
20741 diagnoses of all semantic errors.
20742 (Resolve_Actuals): If the actual is an allocator whose directly
20743 designated type is a class-wide interface we build an anonymous
20744 access type to use it as the type of the allocator. Later, when
20745 the subprogram call is expanded, if the interface has a secondary
20746 dispatch table the expander will add a type conversion to force
20747 the displacement of the pointer.
20748 (Resolve_Call): If a function that returns an unconstrained type is
20749 marked Inlined_Always and inlined, the call will be inlined and does
20750 not require the creation of a transient scope.
20751 (Check_Direct_Boolean_Op): Removed
20752 (Resolve_Comparison_Op): Remove call to above
20753 (Resolve_Equality_Op): Remove call to above
20754 (Resolve_Logical_Op): Inline above, since this is only call.
20755 (Valid_Conversion): Handle properly conversions between arrays of
20756 convertible anonymous access types.
20759 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
20760 the literal in an unchecked conversion, because GCC 4.x needs a static
20761 value for a string bound.
20763 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20764 Hristian Kirtchev <kirtchev@adacore.com>
20766 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
20767 components of the corresponding record, take into account component
20768 definitions that are access definitions.
20769 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
20770 procedure is not considered a dispatching call and will be expanded
20773 2006-02-13 Javier Miranda <miranda@adacore.com>
20775 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
20776 controlling argument of the dispatching call is an abstract interface
20777 class-wide type then we use it directly.
20778 Check No_Dispatching_Calls restriction.
20779 (Default_Prim_Op_Position): Remove the code that looks for the last
20780 entity in the list of aliased subprograms. This code was wrong in
20782 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
20783 when the source is compiled with the No_Dispatching_Calls restriction.
20784 (Init_Predefined_Interface_Primitives): No need to inherit primitives
20785 if we are compiling with restriction No_Dispatching_Calls.
20786 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
20787 subprograms if we are compiling under No_Dispatching_Calls restriction.
20788 (Make_DT): Generate a dispatch table with a single dummy entry if
20789 we are compiling with the No_Dispatching_Calls restriction. In
20790 addition, in this case we don't generate code that calls to the
20791 following run-time subprograms: Set_Type_Kind, Inherit_DT.
20792 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
20793 of this subprogram if compiling with the No_Dispatching_Calls
20795 (Expand_Type_Conversion): Instead of using the actual parameter,
20796 the argument passed as parameter to the conversion function was
20797 erroneously referenced by the expander.
20798 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
20799 Set_Predefined_Primitive_Op_Address and Set_Signature.
20800 (Expand_Dispatching_Call): Generate call to
20801 Get_Predefined_Prim_Op_Address for predefined primitives.
20802 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
20803 predefined primitives.
20804 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
20805 primitives we reserve one dummy entry to ensure that the tag does not
20806 point to some memory that is associated with some other object. In
20807 addition, remove all the old code that generated the assignments
20808 associated with the signature of the dispatch table and replace them
20809 by a call to the new subprogram Set_Signature.
20810 (Set_All_DT_Position): Change the algorithm because now we have a
20811 separate dispatch table associated with predefined primitive operations.
20812 (Expand_Interface_Conversion): In case of non-static offset_to_top
20813 add explicit dereference to get access to the object after the call
20814 to displace the pointer to the object.
20815 (Expand_Interface_Thunk): Modify the generation of the actual used
20816 in the calls to the run-time function Offset_To_Top to fulfil its
20818 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
20820 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20822 * exp_dist.adb (Copy_Specification): For access parameters, copy
20823 Null_Exclusion flag, which will have been set for stream subprograms
20826 2006-02-13 Pascal Obry <obry@adacore.com>
20828 * expect.c (__gnat_expect_portable_execvp): New implementation. The
20829 previous implementation was using the C runtime spawnve routine but
20830 the corresponding wait was using directly the Win32 API. This was
20831 causing some times a lock when waiting for an event using
20832 WaitForSingleObject in __gnat_waitpid. This new implementation uses
20833 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
20834 API fixes this problem.
20836 2006-02-13 Robert Dewar <dewar@adacore.com>
20838 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

20846 array reference that is an explicit dereference, mark the converted
20847 (packed) array reference as analyzed to prevent a forthcoming
20848 reanalysis from resetting its type to the original (non-packed) array
20851 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20852 Javier Miranda <miranda@adacore.com>
20853 Eric Botcazou <ebotcazou@adacore.com>
20855 * exp_util.ads, exp_util.adb (Find_Prim_Op,
20856 Is_Predefined_Primitive_Operation): When
20857 searching for the predefined equality operator, verify that operands
20858 have the same type.
20859 (Is_Predefined_Dispatching_Operation): Remove the code that looks
20860 for the last entity in the list of aliased subprograms. This code
20861 was wrong in case of renamings.
20862 (Set_Renamed_Subprogram): New procedure
20863 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
20864 Exp_Type constant computed when entering this subprogram.
20865 (Known_Null): New function
20866 (OK_To_Do_Constant_Replacement): New function
20867 (Known_Non_Null): Check scope before believing Is_Known_Non_Null flag
20868 (Side_Effect_Free): An attribute reference 'Input is not free of
20869 side effect, unlike other attributes that are functions. (from code
20871 (Remove_Side_Effects): Expressions that involve packed arrays or records
20872 are copied at the point of reference, and therefore must be marked as
20873 renamings of objects.
20874 (Is_Predefined_Dispatching_Operation): Return false if the operation is
20875 not a dispatching operation.
20878 (Remove_Side_Effects): Lift enclosing type conversion nodes for
20879 elementary types in all cases.
20881 2006-02-13 Javier Miranda <miranda@adacore.com>
20883 * freeze.adb (Freeze_Entity): Handle subtypes of protected types and
20884 task types when accessing to the corresponding record type.
20885 Remove '!' in warning message.
20887 2006-02-13 Olivier Hainque <hainque@adacore.com>
20889 * g-altive.ads (VECTOR_ALIGNMENT): Set to Min (16, Max_Alignment),
20890 to avoid useless and space inefficient overalignments on targets where
20891 Max_Alignment is larger than 16.
20893 2006-02-13 Pascal Obry <obry@adacore.com>
20895 * g-catiio.adb (Sec_Number): New type used to compute the number of
20896 seconds since 1-1-1970.
20897 (Image) [Natural]: The parameter was an Integer, as we can't deal with
20898 negative numbers (years, months...) it is better to have a Natural here.
20900 (Image) [Number]: Change parameter from Long_Integer to Number.
20901 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
20902 overflow for dates past year 2038.
20904 2006-02-13 Matthew Heaney <heaney@adacore.com>
20906 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise
20909 2006-02-13 Arnaud Charlet <charlet@adacore.com>
20911 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
20913 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
20914 finalization can occur normally.
20916 2006-02-13 Vincent Celier <celier@adacore.com>
20918 * gnatcmd.adb (Rules_Switches): New table
20919 (Add_To_Rules_Switches): New procedure
20920 (GNATCmd): For command CHECK, put all options following "-rules" in the
20921 Rules_Switches table. Append these -rules switches after the -cargs
20924 2006-02-13 Robert Dewar <dewar@adacore.com>
20926 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
20927 These two cases were generating incorrect output, and if this unit
20928 was built with checks on, generated a discriminant mismatch constraint
20931 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20932 Robert Dewar <dewar@adacore.com>
20934 * lib-xref.adb (Get_Type_Reference): For a private type whose full
20935 view is an array type, indicate the component type as well, for
20936 navigation purposes.
20937 (Generate_Reference): Don't consider array ref on LHS to be a case
20938 of violating pragma Unreferenced.
20939 Do not give Ada 2005 warning except on real reference.
20941 2006-02-13 Vincent Celier <celier@adacore.com>
20943 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
20944 main source, add switch -mdebug-main=_ada_ so that the executable can
20945 be debugged by the standard VMS debugger.
20946 (Gnatmake): Set No_Main_Subprogram to True when there is no main
20947 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
20948 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
20949 of the last source, as the binding and linking phases are never
20951 Set all executable obsolete when rebuilding a library.
20953 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
20956 2006-02-13 Javier Miranda <miranda@adacore.com>
20959 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
20960 code to improve the error message reported when the program has
20961 declarations of abstract interface types and it is not compiled with
20962 the -gnat05 switch.
20963 (P_Access_Definition): Reorganize the code to improve the error
20964 message reported when the new Ada 2005 syntax for anonymous
20965 access types is used and the program is not compiled with the

20979 2006-02-13 Vincent Celier <celier@adacore.com>
20981 * prj.adb (Reset): Initialize the first element of table Namings with
20982 the standard naming data.
20984 2006-02-13 Vincent Celier <celier@adacore.com>
20986 * prj.ads (Error_Warning): New enumeration type
20988 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
20989 unknown, use the location of the project to report the error.
20990 (When_No_Sources): New global variable
20991 (Report_No_Ada_Sources): New procedure
20992 (Check): New parameter When_No_Sources. Set value of global variable
20994 (Find_Sources): Call Report_No_Ada_Sources when appropriate
20995 (Get_Sources_From_File): Ditto
20996 (Warn_If_Not_Sources): Better warning messages indicating the unit name
20999 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
21000 Call Prj.Proc.Process with parameter When_No_Sources.
21002 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
21003 Call Recursive_Check with parameter When_No_Sources.
21004 (Recursive_Check): New parameter When_No_Sources. Call itself and
21005 Prj.Nmsc.Check with parameter When_No_Sources.
21006 (Process): New parameter When_No_Sources. Call Check with parameter
21008 (Copy_Package_Declarations): New procedure to copy renamed parameters
21009 and setting the location of the declared attributes to the location
21010 of the renamed package.

21016 * prj-makr.adb (Make): Preserve the comments from the original project
21018 When removing nodes (attributes Source_Dirs, Source_Files,
21019 Source_List_File and package Naming), save the comments and attach the
21020 saved comments to the newly created nodes.
21021 Do not add a with clause for the naming package if one already exists.

21029 * sem_disp.adb (Override_Dispatching_Operation): Traverse the list of
21030 aliased entities to look for the overriden abstract interface
21032 (Is_Interface_Subprogram): Complete documentation.
21033 (Check_Dispatching_Operation): Do not generate code to register the
21034 operation in the dispatch table if the source is compiled with
21035 restriction No_Dispatching_Calls.
21036 (Override_Dispatching_Operation): Check for illegal attempt to override
21037 No_Return procedure with procedure that is not No_Return
21038 (Check_Dispatching_Call): Suppress the check for an abstract operation
21039 when the original node of an actual is a tag-indeterminate attribute
21040 call, since the attribute, which must be 'Input, can never be abstract.
21041 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
21042 call to the Input attribute (even when rewritten).
21043 (Propagate_Tag): Augment comment to indicate the possibility of a call
21044 to an Input attribute.
21046 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
21047 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.
21049 * s-rident.ads: (No_Dispatching_Calls): New GNAT restriction.
21050 No_Wide_Characters is no longer partition-wide
21051 No_Implementation_Attributes/Pragmas are now Ada 2005 (AI-257)
21054 2006-02-13 Douglas Rupp <rupp@adacore.com>
21056 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
21058 2006-02-13 Javier Miranda <miranda@adacore.com>
21060 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
21061 handles default-initialized components to keep separate the management
21062 of this feature but also avoid the unrequired resolution and
21063 expansion of components that do not have partially initialized
21065 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
21066 (Check_Bounds): Likewise.
21067 (Check_Length): Likewise.
21069 2006-02-13 Javier Miranda <miranda@adacore.com>
21070 Ed Schonberg <schonberg@adacore.com>
21072 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
21073 abstract interface type call analyze_and_resolve to expand the type
21074 conversion into the corresponding displacement of the
21075 reference to the base of the object.
21076 (Eval_Attribute, case Width): For systems where IEEE extended precision
21077 is supported, the maximum exponent occupies 4 decimal digits.
21078 (Accessibility_Message): Add '\' in 2-line warning message.
21079 (Resolve_Attribute): Likewise.
21080 (case Attribute_Access): Significantly revise checks
21081 for illegal access-to-subprogram Access attributes to properly enforce
21082 the rules of 3.10.2(32/2).
21083 Diagnose use of current instance with an illegal attribute.
21085 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
21087 (Enclosing_Generic_Unit): New function to return a node's innermost
21088 enclosing generic declaration node.
21089 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
21090 (Type_Access_Level): The accessibility level of anonymous acccess types
21091 associated with discriminants is that of the current instance of the
21092 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
21093 (Compile_Time_Constraint_Error): Handle case of conditional expression.
21094 (Kill_Current_Values_For_Entity): New function
21095 (Enter_Name): Change formal type to Entity_Id
21097 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>
21098 Ed Schonberg <schonberg@adacore.com>
21099 Gary Dismukes <dismukes@adacore.com>
21101 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
21102 Analyze_Compilation_Unit.
21103 Detect and warn on redundant with clauses detected in a package spec
21104 and/or body when -gnatwr is used.

21106 (Install_Context_Items): Don't analyze config pragmas here
21107 (Install_Limited_Withed_Unit): Set limited entity of package in
21108 with_clause so that cross-reference information or warning messages on
21109 unused packages can be properly generated
21110 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
21111 has Error_Posted set. Prevent infinite loops in illegal programs.
21112 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
21113 to the point of the error test requiring the current unit to be private.
21114 This ensures that private with clauses are not exempted from the basic
21115 checking for being a descendant of the same library unit parent as a
21116 withed private descendant unit.
21117 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
21118 handle private with clauses properly, as well as to account for cases
21119 where the withed unit is a public descendant of a private ancestor
21120 (in which case the current unit must be a descendant of the private
21121 ancestor's parent). The spec comments were updated accordingly. Also,
21122 the old error message in this subprogram was replaced with error
21123 messages that mirror the errors tested and reported by
21124 Check_Private_Child_Unit.
21125 Parameter and variable names improved for readability.
21126 (Install_Limited_Context_Clauses): Remove test for a withed unit being
21127 private as the precondition for calling
21128 Check_Private_Limited_Withed_Unit since that subprogram has been
21129 revised to test public units as well as private units.

21134 Javier Miranda <miranda@adacore.com>
21136 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
21137 that Scope_Stack.First = 1.
21138 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21139 were not always properly handled previously.
21140 (Formal_Entity): Complete rewrite, to handle properly some complex case
21141 with multiple levels of parametrization by formal packages.
21142 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
21143 to the corresponding derived type declaration for proper semantics.
21145 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
21146 (Check_Component): Enforce restriction on components of
21147 unchecked_unions: a component in a variant cannot contain tasks or
21149 (Unchecked_Union): Allow nested variants and multiple discriminants, to
21151 Add pragma Ada_2005 (synonym for Ada_05)
21152 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
21153 were not always properly handled previously.
21154 Document that pragma Propagate_Exceptions has no effect
21155 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
21156 (Set_Convention_From_Pragma): Check that if a convention is
21157 specified for a dispatching operation, then it must be
21158 consistent with the existing convention for the operation.
21159 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
21160 longer required to specify an vtable-ptr component in the record. For
21161 compatibility reasons we leave the support for the previous definition.
21162 (Analyze_Pragma, case No_Return): Allow multiple arguments
21164 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
21165 non-overrideen inherited operation with a controlling result as
21166 illegal only its implicit declaration comes from the derived type
21167 declaration of its result's type.
21168 (Check_Possible_Deferred_Completion): Relocate the object definition
21169 node of the subtype indication of a deferred constant completion rather
21170 than directly analyzing it. The analysis of the generated subtype will
21171 correctly decorate the GNAT tree.
21172 (Record_Type_Declaration): Check whether this is a declaration for a
21173 limited derived record before analyzing components.
21174 (Analyze_Component_Declaration): Diagnose record types not explicitly
21175 declared limited when a component has a limited type.
21176 (Build_Derived_Record_Type): Code reorganization to check if some of
21177 the inherited subprograms of a tagged type cover interface primitives.
21178 This check was missing in case of a full-type associated with a private
21180 (Constant_Redeclaration): Check that the subtypes of the partial and the
21181 full view of a constrained deferred constant statically match.
21182 (Mentions_T): A reference to the current type in an anonymous access
21183 component declaration must be an entity name.
21184 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
21185 class_wide type to refer to full type, not to the incomplete one.
21186 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
21187 available. Required to give support to the certified run-time.
21188 (Analyze_Component_Declaration): In case of anonymous access components
21189 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
21190 (Process_Discriminants): For an access discriminant, use the
21191 discriminant specification as the associated_node_for_itype, to
21192 simplify accessibility checks.

21195 Javier Miranda <miranda@adacore.com>
21197 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
21198 abstract interpretations on an operator, remove interpretations that
21199 yield Address or a type derived from it, if one of the operands is an
21201 (Try_Object_Operation.Try_Primitive_Operation,
21202 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
21203 location when creating the new reference to a primitive or class-wide
21204 operation as a part of rewriting a subprogram call.
21205 (Try_Primitive_Operations): If context requires a function, collect all
21206 interpretations after the first match, because there may be primitive
21207 operations of the same type with the same profile and different return
21208 types. From code reading.
21209 (Try_Primitive_Operation): Use the node kind to choose the proper
21210 operation when a function and a procedure have the same parameter
21212 (Complete_Object_Operation): If formal is an access parameter and prefix
21213 is an object, rewrite as an Access reference, to match signature of
21214 primitive operation.
21215 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
21216 by an expanded name with prefix Standard, when the operands are of an
21217 anonymous access type.
21218 (Remove_Abstract_Operations): If the operation is abstract because it is
21219 inherited by a user-defined type derived from Address, remove it as
21220 well from the set of candidate interpretations of an overloaded node.
21221 (Analyze_Membership_Op): Membership test not applicable to cpp-class
21224 2006-02-13 Bob Duff <duff@adacore.com>
21226 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
21227 redundant use clauses.
21228 In particular, if the scope of two use clauses overlaps, but one is not
21229 entirely included in the other, we should not warn. This can happen
21230 with nested packages.
21231 (Analyze_Subprogram_Renaming): Protect the compiler against previously
21232 reported errors. The bug was reported when the compiler was built
21233 with assertions enabled.
21234 (Find_Type): If the node is a 'Class reference and the prefix is a
21235 synchronized type without a corresponding record, return the type
21238 2006-02-13 Javier Miranda <miranda@adacore.com>
21240 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
21241 if this is the full-declaration associated with a private declaration
21242 that implement interfaces, then the private type declaration must be
21244 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
21245 as aliased. The use of the 'access attribute is not available for such
21246 object (for this purpose the object should be explicitly marked as
21247 aliased, but being an anonymous type this is not possible).
21249 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21250 Robert Dewar <dewar@adacore.com>
21252 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
21253 compilation unit is an elaboration scope.
21254 (Add_Task_Proc): Add '\' in 2-line warning message.
21255 (Activate_All_Desirable): Deal with case of unit with'ed by parent
21257 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21258 Javier Miranda <miranda@adacore.com>
21260 * sem_type.adb (Write_Overloads): Improve display of candidate
21262 (Add_One_Interp): Do not add to the list of interpretations aliased
21263 entities corresponding with an abstract interface type that is an
21264 immediate ancestor of a tagged type; otherwise we have a dummy
21265 conflict between this entity and the aliased entity.
21266 (Disambiguate): The predefined equality on universal_access is not
21267 usable if there is a user-defined equality with the proper signature,
21268 declared in the same declarative part as the designated type.
21269 (Find_Unique_Type): The universal_access equality operator defined under
21270 AI-230 does not cover pool specific access types.
21271 (Covers): If one of the types is a generic actual subtype, check whether
21272 it matches the partial view of the other type.
21274 2006-02-13 Thomas Quinot <quinot@adacore.com>
21276 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
21277 line. This is necessary to allow In_Extended_Main_Unit to provide
21278 correct results for itypes while writing out expanded source.
21279 (Close_File): No need to update the source_index_table here since it's
21280 now done for each line.
21282 2006-02-13 Ed Schonberg <schonberg@adacore.com>
21283 Robert Dewar <dewar@adacore.com>
21285 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
21286 preserve the source unit where the itype is declared, and prevent a
21288 (Note_Implicit_Run_Time_Call): New procedure
21289 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
21292 * sprint.ads: Document use of $ for implicit run time routine call
21294 2006-02-13 Quentin Ochem <ochem@adacore.com>
21296 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
21299 2006-02-13 Bob Duff <duff@adacore.com>
21301 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
21302 Scan_Unsigned, so we do not scan leading blanks and sign twice.
21303 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21304 raise Constraint_Error.
21306 * s-vallli.adb (Scan_Long_Long_Integer): Call
21307 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
21308 do not scan leading blanks and sign twice.
21309 Integer'Value("- 5") and Integer'Value("-+5") now correctly
21310 raise Constraint_Error.
21312 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
21313 Scan_Long_Long_Unsigned): Split out most of the processing from
21314 Scan_Long_Long_Unsigned out into
21315 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.
21316 This prevents scanning leading blanks and sign twice.
21317 Also fixed a bug: Modular'Value("-0") should raise Constraint_Error
21320 * s-valuns.ads, s-valuns.adb (Scan_Raw_Unsigned, Scan_Unsigned): Split
21321 out most of the processing from Scan_Unsigned out into
21322 Scan_Raw_Unsigned, so that Val_LLI can call the Raw_ version.
21323 This prevents scanning leading blanks and sign twice.
21325 * s-valuti.ads, s-valuti.adb (Scan_Plus_Sign): Add Scan_Plus_Sign, for
21326 use with Modular'Value attribute.
21327 (Scan_Plus_Sign): Add Scan_Plus_Sign, for use with Modular'Value
21330 2006-02-13 Robert Dewar <dewar@adacore.com>
21332 * s-wchjis.adb (JIS_To_EUC): Raise Constraint_Error for invalid value
21334 2006-02-13 Eric Botcazou <ebotcazou@adacore.com>
21336 * tracebak.c (PPC AIX/Darwin): Define FORCE_CALL to 1.
21337 (PPC VxWorks): Likewise.
21338 (Generic unwinder): Define FORCE_CALL to 0 if not already defined.
21339 (forced_callee): Make non-inlinable and non-pure.
21340 (__gnat_backtrace): Call forced_callee if FORCE_CALL is set to 1.

21343 Ben Brosgol <brosgol@adacore.com>
21344 Robert Dewar <dewar@adacore.com>

21482 (../../vxaddr2line): gnatlink with targext.o.
21483 (TOOLS_LIBS): Move targext.o to precede libgnat.
21484 (init.o, initialize.o): Minor clean up in dependencies.

21522 Quentin Ochem <ochem@adacore.com>
21523 Florian Villoing <villoing@adacore.com>
21525 * a-taster.ads, a-taster.adb: New files.
21527 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
21528 link to the version that does nothing. This way the task termination
21529 routine is not executed twice for the environment task when finishing
21530 because of an unhandled exception.
21532 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
21533 handler because of an unhandled exception.
21535 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from
21536 System.Tasking.Utilities instead of that in System.Tasking.Stages.
21538 * s-finimp.adb (initialization code): Modify the soft link for the
21539 finalization of the global list instead of Adafinal.
21541 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
21542 non-tasking version of the soft link for task termination. We do
21543 nothing since if we are using the non-tasking version it
21544 means that the task termination functionality is not used.
21545 (Null_Finalize_Global_List): Add this null version for the procedure
21546 in charge of finalizing the global list for controlled objects.
21547 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
21548 instead for handling run-time termination in a more flexible way.
21549 (Adafinal_NT): This new procedure will take care of finalizing the
21550 global list for controlled objects if needed, but no tasking
21553 * s-tarest.adb (Task_Lock): Do not try to lock again the
21554 Global_Task_Lock if we already own it. Otherwise, we get blocked in
21555 some run-time operations.
21556 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
21557 until all nested locks have been released.
21558 (Task_Wrapper): Call the fall-back task termination handler. It
21559 applies to all tasks but the environment task.
21560 (Finalize_Global_Tasks): Add the call for the task termination
21561 procedure for the environment task.
21562 (Task_Wrapper): suppress warnings around declaration of
21563 Secondary_Stack_Address.
21565 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
21566 moved to the Common_ATCB record.
21567 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
21568 Common_ATCB record.
21569 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
21570 Common_ATCB record.
21572 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
21573 Fall_Back_Handler, and Specific_Handler.
21575 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
21576 defined in Ada.Task_Termination, to avoid circular dependencies.
21577 (Termination_Handler): Redefine this type here, alredy defined in
21578 Ada.Task_Termination, for avoiding circular dependencies.
21579 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
21580 for storing task termination handlers. In addition,
21581 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
21582 Common_ATCB because it is used by both the regular and the restricted
21584 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
21585 Common_ATCB because it is used by both the regular and the restricted
21587 (Common_ATCB): Added a dynamic task analyzer field.
21589 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
21590 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
21591 (Task_Wrapper): Call the task termination handler. It applies to all
21592 tasks but the environment task.
21593 (Finalize_Global_Tasks): Call the task termination procedure for the
21594 environment task. The call to Finalize_Global_List is now performed
21595 using the soft links mechanism.
21596 (Task_Wrapper): added dynamic stack analysis.
21598 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
21599 potentially blocking operations has been moved from
21600 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
21601 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
21602 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
21603 this run-time check.
21605 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
21606 of task termination procedure.
21607 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
21608 link for the task termination procedure.
21610 * bindusg.adb: (Bindusg): Added documentation for -u option.
21612 * bindgen.adb (Get_Main_Ada) Added handling of dynamic stack analysis.

21620 * opt.ads: Added flags used by dynamic stack measurement.
21621 (Max_Line_Length): Remove (not used anymore)
21623 * s-io.ads, s-io.adb (Standard_Error): new subprogram
21624 (Standart_Output): new subprogram
21625 (Set_Output): new subprogram
21626 (Put): now uses the value of Current_Out to know if the output has to be
21627 send to stderr or stdout.
21629 * s-stausa.ads: Complete implementation.
21631 * switch-b.adb: Added handling of -u switch for dynamic stack analysis.
21633 * impunit.adb (Non_Imp_File_Names_05): Add Ada.Task_Termination to the
21634 list of Ada 05 files.
21635 (GNAT Library Units): Add AltiVec files.
21637 * g-allein.ads, g-alleve.adb, g-alleve.ads, g-altcon.adb,
21638 g-altcon.ads, g-altive.ads, g-alveop.adb, g-alveop.ads
21639 g-alvety.ads, g-alvevi.ads: New files providing altivec API.
21641 2005-12-09 Nicolas Setton <setton@adacore.com>
21643 * adaint.c (__gnat_locate_regular_file): Return immediately if
21644 file_name is empty.
21646 2005-12-09 Javier Miranda <miranda@adacore.com>
21647 Hristian Kirtchev <kirtchev@adacore.com>
21649 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
21650 to the specification because the frontend generates code that uses this
21652 (Set_Interface_Table): Add missing assertion.
21653 Update documentation describing the run-time structure.
21654 (Displace): New subprogram that displaces the pointer to the object
21655 to reference one of its secondary dispatch tables.
21656 (IW_Membership): Modified to use the new table of interfaces.
21657 (Inherit_TSD): Modified to use the new table of interfaces.
21658 (Register_Interface_Tag): Use the additional formal to fill the
21659 contents of the new table of interfaces.
21660 (Set_Interface_Table): New subprogram that stores in the TSD the
21661 pointer to the table of interfaces.
21662 (Set_Offset_To_Top): Use the additional formal to save copy of
21663 the offset value in the table of interfaces.
21664 Update structure of GNAT Primary and Secondary dispatch table diagram.
21665 Add comment section on GNAT dispatch table prologue.
21666 (Offset_To_Signature): Update the constant value of the Signature field.
21667 (Dispatch_Table): Update comment on hidden fields in the prologue.
21668 (Get_Entry_Index, Get_Prim_Op_Kind, Get_Offset_Index, OSD,
21669 Set_Entry_Index, Set_Offset_Index, Set_Prim_Op_Kind, SSD, TSD): Change
21670 the type of formal parameter T to Tag, introduce additional assertions.
21671 (Get_Num_Prim_Ops, Set_Num_Prim_Ops): Remove an unnecessary type
21673 (Get_Tagged_Kind, Set_Tagged_Kind): New bodies.
21675 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
21676 in all the calls to Expand_Interface_Thunk. Instead of referencing the
21677 record component containing the tag of the secondary dispatch table we
21678 have to use the Offset_To_Top run-time function to get this information;
21679 otherwise if the pointer to the base of the object has been displace
21680 we get a wrong value if we use the 'position attribute.
21682 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
21683 all the calls to Expand_Interface_Thunk.
21684 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
21685 interfaces; hence the call to Set_Interface_Table was clearly wrong.
21686 (Collect_All_Interfaces): Modify the internal subprogram Collect to
21687 ensure that the interfaces implemented by the ancestors are placed
21688 at the header of the generated list.
21689 (Expand_Interface_Conversion): Handle the case in which the displacement
21690 associated with the interface conversion is not statically known. In
21691 this case we generate a call to the new run-time subprogram Displace.
21692 (Make_DT): Generate and fill the new table of interfaces.
21693 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for

22011 available user-specified stream attributes on limited parameters to
22012 also test the type directly rather than only its underlying type (for
22013 Ada 95) and, in the case of Ada 2005, to check that the user-specified
22014 attributes are visible at the point of the subprogram declaration.
22015 For Ada 2005, the error message is modified to indicate that the
22016 type's stream attributes must be visible (again, only for -gnat05).

22296 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for

22342 * exp_vfpt.adb: Handle /= case
22343 (Expand_Vax_Conversion): Properly recognize Conversion_OK flag

22351 Increase default priority on Lynx from 15 to 17, and meet the Ada
22352 requirement that Default_Priority be ((Priority'First +

22455 we are not defining the type.
22456 <E_Record_Type>: Likewise.
22457 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
22458 to get advantage of the new maybe_stabilize_reference interface, to

22461 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
22462 type imported through a limited_with clause, use its non-limited view.
22463 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

22468 before early-returning for certain types when code generation is

22472 that we are not defining.
22473 (elaborate_expression_1): Do not create constants when creating
22474 variables needed by the debug info: the dwarf2 writer considers that
22475 CONST_DECLs is used only to represent enumeration constants, and emits
22477 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
22478 object with an address clause into an indirect reference, drop the

22491 subtype to build an actual type with bounds template.
22492 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
22493 is provided by the front-end, use that subtype to compute the size of
22494 the deallocated object.

22496 check for a potential violation of a No_Elaboration_Code restriction.

22501 maybe_stabilize, for common uses without restriction on lvalues and
22502 without need to check for the success indication.
22503 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
22504 pass false instead of 0 as the FORCE argument which is a bool.
22505 (Identifier_to_gnu): Remove checks ensuring that an renamed object
22506 attached to a renaming pointer has been properly stabilized, as no such
22507 object is attached otherwise.
22508 (call_to_gnu): Invoke create_var_decl to create the temporary when the
22509 function uses the "target pointer" return mechanism.
22510 Reinstate conversion of the actual to the type of the formal
22511 parameter before any other specific treatment based on the passing

22522 static output of record constructor if all the components are constant.
22523 (gnat_build_constructor): For a record type, sort the list of field
22524 initializers in increasing bit position order.

22526 from a fat or thin pointer type and a constrained object type.
22527 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
22528 types variants, and process special cases of VIEW_CONVERT expressions
22529 as their NOP_EXPR counterpart to ensure we get to the
22530 CORRESPONDING_VARs associated with CONST_DECls.
22531 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
22532 on the right-hand side.

22539 extracting the object if converting to a type variant.
22540 (create_var_decl): When a variable has an initializer requiring code
22541 generation and we are at the top level, check for a potential violation
22542 of a No_Elaboration_Code restriction.
22543 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

22686 * exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
22687 for task component, in the case of a limited aggregate. The enclosed
22688 object declaration will create it earlier. Otherwise, in the case of a
22689 nested aggregate, the object may appear in the wrong scope.
22690 (Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
22691 (Gen_Assign): If the component being assigned is an array type and the
22692 expression is itself an aggregate, wrap the assignment in a block to
22693 force finalization actions on the temporary created for each row of the
22695 (Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
22696 structures are initialized after all discriminants are set so that
22697 they can be accessed even when their offset is dynamic.

22725 * exp_attr.adb (Expand_N_Attribute_Reference, cases of Attribute_Size
22726 and related): For a prefix that is an explicit dereference of an

22728 with an actual subtype so GIGI can make a correct size computation.
22729 (Expand_N_Attribute_Reference): In case of 'Unchecked_Access and
22730 'Unrestricted_Access, if the designated type is an interface we
22731 add a type conversion to force the displacement of the pointer
22732 to the secondary dispatch table.
22733 Use Universal_Real instead of Long_Long_Float when we need a high
22734 precision float type for the generated code (prevents gratuitous
22735 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
22736 (Expand_N_Attribute_Reference): Add support for attribute 'Callable and
22737 'Terminated for task interface class-wide objects. Generate a call to
22738 the predefined dispatching routine used to retrieve the _task_id from
22739 a task corresponding record.

22764 if-statement that has elsif_parts, recompute the Current_Value node
22765 for any entity whose value is known from the condition of the first
22767 (Expand_N_Return_Statement): When returning a mutable record, convert
22768 the return value into its actual subtype in order to help the backend
22769 to return the actual size instead of the maximum. This is another
22770 aftermath of not returning mutable records on the sec-stack anymore.
22772 * sem_ch5.ads, sem_ch5.adb (Analyze_Iteration_Scheme): Minor change to
22773 handling of error msg for suspicious reverse range iteration.
22774 (Check_Possible_Current_Value_Condition): Move declaration from body to

22797 2005-11-14 Robert Dewar <dewar@adacore.com>
22799 * exp_fixd.adb: Use Universal_Real instead of Long_Long_Float when we
22800 need a high precision float type for the generated code (prevents
22801 gratuitous Vax_Float stuff when pragma Float_Representation (Vax_Float)

22819 attribute of the N_Free_Statement.
22820 Generate itype for classwide designated object in both cases of
22821 user-specified storage pool: specific and class-wide, not only in the
22823 Raise CE when trying to set a not null access type object to null.
22824 (Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
22825 an explicit loop, because freeze nodes make its position variable.

23062 scope against package Standard. Add comments and a ??? comment.
23063 (Remove_Parent): Revise condition for resetting Is_Immediately_Visible
23064 on a child instance parent to test that the parent equals

23084 full view to construct the full declaration of the derived type.
23085 (Build_Derived_Record_Type): Relax the condition that controls the
23086 execution of the check that verifies that the partial view and

23096 (Process_Full_View): Rename local subprogram Find_Interface_In_
23097 Descendant to Find_Ancestor_Interface to leave the code more clear.
23098 Remove wrong code that avoids the generation of an error message
23099 when the immediate ancestor of the partial view is an interface.
23100 In addition some minor reorganization of the code has been done to
23101 leave it more clear.
23102 (Analyze_Type_Declaration): If type has previous incomplete tagged
23103 partial view, inherit properly its primitive operations.
23104 (Collect_Interfaces): Make public, for analysis of formal

23117 be included in the interface list.
23118 (Access_Definition): If the designated type is an interface that may
23119 contain tasks, create Master_Id for it before analyzing the expression
23120 of the declaration, which may be an allocator.

23131 subprogram declaration.
23132 Change name Is_Package to Is_Package_Or_Generic_Package
23133 (Process_Formals): A non null qualifier on a non null named access
23134 type is not an error, and is a warning only if Redundant_Constructs

23140 * sem_ch7.adb (Install_Parent_Private_Declarations): New procedure
23141 nested within Analyze_Package_Specification to install the private
23142 declarations and use clauses within each of the parent units of a
23143 package instance of a generic child package.
23144 (Analyze_Package_Specification): When entering a private part of a
23145 package associated with a generic instance or formal package, the
23146 private declarations of the parent must be installed (by calling new
23147 procedure Install_Parent_Private_Declarations).
23148 Change name Is_Package to Is_Package_Or_Generic_Package
23149 (Preserve_Full_Attributes): For a synchronized type, the corresponding
23150 record is absent in a generic context, which does not indicate a
23153 2005-11-14 Ed Schonberg <schonberg@adacore.com>
23155 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic context, do
23156 not try to rewrite a renamed stream attribute, because the operations
23157 on the type may not have been generated.
23158 Handle properly a renaming_as_body generated for a stream operation
23159 whose default is abstract because the object type itself is abstract.
23160 (Find_Type): If the type is incomplete and appears as the prefix of a
23161 'Class reference, it is tagged, and its list of primitive operations
23162 must be initialized properly.
23163 (Chain_Use_Clauses): When chaining the use clauses that appear in the
23164 private declaration of a parent unit, prior to compiling the private
23165 part of a child unit, find on the scope stack the proper parent entity
23166 on which to link the use clause.
23167 (Note_Redundant_Use): Emit a warning when a redundant use clause is
23169 (Analyze_Object_Renaming): An attribute reference is not a legal object
23170 if it is not a function call.

23173 Ed Schonberg <schonberg@adacore.com>
23175 * sem_eval.adb: Implement d.f flag
23176 (Subtype_Statically_Match): A generic actual type has unknown
23177 discriminants when the corresponding actual has a similar partial view.
23178 If the routine is called to validate the signature of an inherited
23179 operation in a child instance, the generic actual matches the full view,

23186 * sem_res.adb (Resolve_Call): Provide a better error message whenever
23187 a procedure call is used as a select statement trigger and is not an
23188 entry renaming or a primitive of a limited interface.
23189 (Valid_Conversion): If the operand has a single interpretation do not
23190 remove address operations.
23191 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
23192 statement to inhibit warning.
23193 (Resolve_Unary_Op): Do not produce a warning when
23194 processing an expression of the form -(A mod B)
23195 Use Universal_Real instead of Long_Long_Float when we need a high
23196 precision float type for the generated code (prevents gratuitous
23197 Vax_Float stuff when pragma Float_Representation (Vax_Float) used)
23198 (Resolve_Concatenation_Arg): Improve error message when argument is an
23199 ambiguous call to a function that returns an array.
23200 (Make_Call_Into_Operator, Operand_Type_In_Scope): Do not check that
23201 there is an implicit operator in the given scope if we are within an
23202 instance: legality check has been performed on the generic.
23203 (Resolve_Unary_Op): Apply warnings checks on argument of Abs operator
23204 after resolving operand, to avoid false warnings on overloaded calls.
23206 2005-11-14 Ed Schonberg <schonberg@adacore.com>
23207 Javier Miranda <miranda@adacore.com>
23210 * sem_type.adb (Covers): In an inlined body, a composite type matches
23211 a private type whose full view is a composite type.
23212 (Interface_Present_In_Ancestor): Protect the frontend against
23213 previously detected errors to ensure that its compilation
23214 with assertions enabled gives the same output that its
23215 compilation without assertions.
23216 (Interface_Present_In_Ancestor): Add support for private types.
23217 Change name In_Actual to In_Generic_Actual (clean up)
23218 (Disambiguate): New predicate In_Actual, to recognize expressions that
23219 appear in the renaming declaration generated for generic actuals, and
23220 which must be resolved in the outer context.

23231 (Set_Public_Status): Do not set Is_Public on an object whose declaration
23232 occurs within a handled_sequence_of_statemets.
23233 (Is_Controlling_Limited_Procedure): Factor some of the logic, account
23234 for a parameterless procedure.
23235 (Enter_Name): Recognize renaming declarations created for private
23236 component of a protected type within protected operations, so that
23237 the source name of the component can be used in the debugger.

23248 * par-prag.adb: Modify processing of pragma Warnings to accomodate new
23249 form with a string literal argument

23886 entity of a primitive wrapper.
23887 (Write_Entity_Flags): Output the name and value of the
23888 Is_Primitive_Wrapper attribute.
23889 (Write_Field27_Name): Output the name and entity of the field Wrapped_
23891 (Underlying_Type): If we have an incomplete entity that comes from
23892 the limited view then we return the Underlying_Type of its non-limited
23893 view if it is already available.
23894 (Abstract_Interface_Alias): Flag applies to all subrogram kinds,
23895 including operators.
23896 (Write_Field26_Name): Add entry for Overridden_Operation

23900 predefined position in the dispatch table for the primitive operations
23901 used in dispatching selects.
23902 (Init_Predefined_Interface_Primitives): Remove the hardcoded number of
23903 predefined primitive operations and replace it with
23904 Default_Prim_Op_Count.

23906 Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Update
23907 the names of the generated primitive operations used in dispatching
23909 (Init_Predefined_Interface_Primitives): No need to inherit primitives in
23910 case of abstract interface types. They will be inherit by the objects
23911 implementing the interface.

23913 ancestor interface for the elaboration of abstract interface types.
23914 The dispatch table will be inherited by the object implementing the

23923 (Build_Anonymous_Access_Type): Removed.
23924 (Expand_Interface_Actuals): With the previous cleanup there is no need
23925 to build an anonymous access type. This allows further cleanup in the
23926 code generated by the expander.
23927 (Expand_Interface_Conversion): If the actual is an access type then
23928 build an internal function to handle the displacement. If the actual
23929 is null this function returns null because no displacement is
23930 required; otherwise performs a type conversion that will be
23931 expanded in the code that returns the value of the displaced actual.
23932 (Expand_Interface_Actuals): Avoid the generation of unnecessary type
23933 conversions that have no effect in the generated code because no
23934 displacement is required. Code cleanup; use local variables to
23935 avoid repeated calls to the subprogram directly_designated_type().

23943 (Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
23944 (Expand_Subtype_From_Expr): Do not build actual subtype if the
23945 expression is limited.
23946 (Find_Interface_Tag): Add code to handle class-wide types and
23947 entities from the limited-view.
23949 * rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
23950 Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
23951 POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,
23952 POK_Task_Entry, POK_Task_Procedure, Prim_Op_Kind, Set_Entry_Index,

23977 (Initialize): Call Interrupt_Managemeent.Initialize to ensure proper
23978 initialization of this unit.
23979 (Specific): Add new procedures Initialize and Delete so that this
23980 package can be used for VxWorks 5.x and 6.x
23981 (ATCB_Key, ATCB_Key_Address): Moved to Specific package body to hide
23982 differences between VxWorks 5.x and 6.x
23983 Minor reformatting.
23984 (Timed_Delay): Remove calls to Defer/Undefer_Abort, now performed by

24004 * adaint.c: The wait.h header is not located in the sys directory on
24005 VxWorks when using RTPs.
24006 (__gnat_set_env_value): Use setenv instead of putenv on VxWorks when
24008 (__gnat_dup): dup is available on Vxworks when using RTPs.
24009 (__gnat_dup2): dup2 is available on Vxworks when using RTPs.
24011 * cal.c: Use the header time.h for Vxworks 6.0 when using RTPs.
24013 * expect.c: The wait.h header is not located in the sys directory on
24014 VxWorks when using RTPs.

24036 Move all target-specific file inclusions and macro definitions to
24037 gsocket.h, in order to ensure that any C code in socket.c will see a set
24038 of constants that is consistent with the contents of g-soccon.ads.
24039 This change also makes gen-soccon self-contained (removing dependencies
24040 upon GCC internal headers).
24042 * g-socket.adb (Send_Vector): Make calls to Writev at most IOV_MAX
24044 (To_Inet_Addr): Now a procedure instead of a function, more efficient.
24046 * socket.c: Minor reformatting.

24175 Hristian Kirtchev <kirtchev@adacore.com>
24176 Javier Miranda <miranda@adacore.com>
24178 * exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
24179 from object notation, the original node is unanalyzed and carries no
24180 semantic information, so that accessiblity checks must be performed on
24181 the type of the actual itself.
24182 (Expand_N_Subprogram_Declaration): Change last actual parameter for
24183 compatibility with Build_Protected_Sub_Specification.
24184 (Check_Overriding_Inherited_Interfaces): Add suport to handle
24185 overloaded primitives.

24190 include the generation of dispatching subprograms when the type
24191 implements at least one interface.
24193 * lib.ads: Extend information in Load_Stack to include whether a given
24194 load comes from a Limited_With_Clause.
24196 * lib-load.adb (From_Limited_With_Chain): New predicate to determine
24197 whether a potential circularity is harmless, because it includes units
24198 loaded through a limited_with clause. Extends previous treatment which
24199 did not handle properly arbitrary combinations of limited and
24200 non-limited clauses.
24202 2005-09-01 Nicolas Setton <setton@adacore.com>
24204 * exp_dbug.adb (Get_Encoded_Name): Fixed bug that caused biaised types
24205 to be encoded as typ___XBLU_lowerbound__upperbound instead of

24232 (Close): Deallocate any existing filter for the concerned connection
24234 2005-09-01 Laurent Pautet <pautet@adacore.com>
24236 * g-pehage.ads, g-pehage.adb (Select_Char_Position): When no character
24237 position set is provided, we compute one in order to reduce the maximum
24238 length of the keys. This computation first selects a character
24239 position between 1 and the minimum length of the keys in order to
24240 avoid reducing one of the keys to an empty string.
24241 (Initialize, Compute): When the ratio V to K is too low, the algorithm
24242 does not converge. The initialization procedure now comes with a
24243 maximum number of iterations such that when exceeded, an exception is
24244 raised in Compute. The user can initialize this ratio to another value
24246 Reformating and updated headers.

24250 * itypes.ads, itypes.adb (Create_Null_Excluding_Itype): New subprogram
24251 that given an entity T creates and returns an Itype that duplicates the
24252 contents of T. The returned Itype has the null-exclusion
24253 attribute set to True, and its Etype attribute references T
24254 to keep the association between the two entities.
24255 Update copyright notice
24257 * sem_aggr.adb (Check_Can_Never_Be_Null,
24258 Aggregate_Constraint_Checks, Resolve_Aggregate,
24259 Resolve_Array_Aggregate, Resolve_Record_Aggregate): Code cleanup.
24261 * sem_ch5.adb (Analyze_Assignment): Code cleanup.

24272 Call Set_Result_Definition instead of Set_Subtype_Mark.
24273 (P_Subprogram_Specification): Add parsing of anonymous access result
24274 plus null exclusions. Call Set_Result_Definition instead of
24277 * par-ch3.adb: Add support for LIMITED NEW for Ada 2005 AI-419
24278 (P_Access_Type_Definition): Add parsing for an anonymous access result
24279 subtype, plus parsing for null exclusions. Call Set_Result_Definition
24280 instead of Set_Subtype_Mark.
24282 * sinfo.adb: Add support for LIMITED NEW for Ada 2005 AI-419
24283 (Null_Exclusion_Present): Allow this flag for N_Function_Specification.
24284 (Result_Definition): New function for N_Function_Specifications.
24285 (Subtype_Mark): No longer allowed for N_Access_Function_Definition and
24286 N_Function_Specification.
24287 (Set_Null_Exclusion_Present): Allow this flag for
24288 N_Function_Specification.
24289 (Set_Result_Definition): New procedure for N_Function_Specifications.
24290 (Set_Subtype_Mark): No longer allowed for N_Access_Function_Definition
24291 and N_Function_Specification.
24293 * sinfo.ads: Update grammar rules for 9.7.2: Entry_Call_Alternative,
24294 Procedure_Or_Entry_Call; 9.7.4: Triggering_Statement.
24295 Add support for LIMITED NEW for Ada 2005 AI-419
24296 Update the syntax of PARAMETER_AND_RESULT_PROFILE to reflect the new
24297 syntax for anonymous access results.
24298 Replace Subtype_Mark field by Result_Definition in
24299 N_Function_Specification and N_Access_Definition specs.
24300 Add Null_Exclusion_Present to spec of N_Function_Specification.
24301 (Result_Definition): New function for N_Function_Specification and
24302 N_Access_Function_Definition.
24303 (Set_Result_Definition): New procedure for N_Function_Specification and
24304 N_Access_Function_Definition.
24306 * sprint.adb (S_Print_Node_Actual): Change Subtype_Mark calls to
24307 Result_Definition for cases of N_Access_Function_Definition and
24308 N_Function_Specification.
24309 Print "not null" if Null_Exclusion_Present on N_Function_Specification.
24311 2005-09-01 Vincent Celier <celier@adacore.com>
24313 * lib-writ.adb: Update Copyright notice
24314 (Write_With_Lines): On platforms where file names are case-insensitive,
24315 record the file names in lower case.
24316 (Write_ALI): For D lines, on platforms where file names are
24317 case-insensitive, record the file names in lower case.
24319 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24320 Emmanuel Briot <briot@adacore.com>

24327 * ali.ads (Xref_Entity_Record): Add support for storing the overriding
24330 * ali.adb (Get_Typeref): New subprogram. Adds support for parsing the
24331 overriding entity information.
24333 2005-09-01 Vincent Celier <celier@adacore.com>
24335 * mlib-prj.adb (Copy_Interface_Sources): Copy all interface sources,
24336 including those that are inherited.
24338 2005-09-01 Robert Dewar <dewar@adacore.com>
24340 * opt.ads, opt.adb: Add new switches Debug_Pragmas_Enabled[_Config]
24342 * par-prag.adb: Implement new pragma Debug_Policy
24344 * sem_prag.adb Implement new pragma Debug_Policy
24345 (Analyze_Pragma, case Pack): do not let pragma Pack override an explicit
24346 Component_Size attribute specification. Give warning for ignored pragma
24349 * snames.h, snames.ads, snames.adb: Introduce entries in
24350 Preset_Names for Name_Disp_Asynchronous_Select,
24351 Name_Disp_Conditional_Select, Name_Disp_Get_Prim_Op_Kind,
24352 Name_Disp_Timed_Select.
24353 New pragma Debug_Policy
24355 * switch-c.adb (Scan_Front_End_Switches): Set Ada 2005 mode
24357 Switch -gnata also sets Debug_Pragmas_Enabled
24359 * sem.adb, par.adb (Set_Opt_Config_Switch): Add parameter Main_Unit to
24360 handle an explicit -gnata when compiling predefined files.
24362 2005-09-01 Vincent Celier <celier@adacore.com>
24364 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
24365 directories of projects that have no Ada sources.
24367 2005-09-01 Robert Dewar <dewar@adacore.com>
24369 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
24370 (makes a difference for wide characters)
24372 * widechar.adb, widechar.ads:
24373 Add Wide_Char_Byte_Count feature to count chars vs bytes
24375 2005-09-01 Thomas Quinot <quinot@adacore.com>
24376 Ed Schonberg <schonberg@adacore.com>
24377 Robert Dewar <dewar@adacore.com>
24379 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
24380 'Address attribute reference with an overloaded prefix, use the
24381 location of the prefix (not the location of the attribute reference) as
24382 the error location.
24383 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
24384 a function renaming thereof, is a valid prefix for 'Size (where it is
24385 intepreted as a function call).
24386 (Statically_Denotes_Entity): New predicate to determine whether the
24387 prefix of an array attribute can be considered static.
24390 (Eval_Attr): Fix failure to evaluate Component_Size for
24391 unconstrained arrays (resulted in wrong value in packed case, since
24392 back end cannot handle this case)
24394 2005-09-01 Robert Dewar <dewar@adacore.com>
24396 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
24397 error msgs for most common cases.
24398 Use new errout insertion char < (conditional warning)
24400 2005-09-01 Javier Miranda <miranda@adacore.com>
24401 Ed Schonberg <schonberg@adacore.com>
24403 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
24404 become local to the whole package.
24405 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
24406 the package was already analyzed the new algorithm "replaces" the
24407 real entities by the shadow ones. This is required to ensure that
24408 the order of these entities in the homonym chains does not change;
24409 otherwise we can have undefined references at linking time because
24410 in case of conflicts the external name of the entities will have
24411 a suffix that depends on the order of the entities in the chain.
24412 (Remove_Limited_With_Clause): Complementary code that completes the
24413 new algorithm and replaces the shadow entities by the real ones.
24414 (Install_Limited_Withed_Unit): When unchaining entities before the
24415 installation of the shadow entities, only regular entities of the
24416 public part must be taken into account. This is required to
24417 keep this routine in synch with the work done by Remove_Limited_
24419 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
24420 even if unit is analyzed, because the analysis of the unit is
24421 idempotent in any case, and the limited view of the unit may have to
24422 be installed for proper visibility.
24423 (Expand_Limited_With_Clause): Even if the unit in the implicit
24424 with_clause has been analyzed already, a limited view of the package
24425 must be built for the current context, if it does not exist yet.
24427 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24428 Javier Miranda <miranda@adacore.com>
24429 Gary Dismukes <dismukes@adacore.com>
24431 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
24432 defining entity for the instance body, make a new defining identifier
24433 rather than copying the entity of the spec, to prevent accidental
24434 sharing of the entity list.
24435 (Check_Private_View): When exchanging views of private types, build the
24436 list of exchanged views as a stack, to ensure that on exit the exchanges
24437 are undone in the proper order.
24438 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
24439 Restore the compilation environment in case of instantiation_error.
24440 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
24441 for an anonymous access result.
24442 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
24443 (Formal_Entity): Handle properly the case of a formal package that
24444 denotes a generic package renaming.
24446 2005-09-01 Thomas Quinot <quinot@adacore.com>
24448 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
24449 clause if the array aggregate is surrounded by parentheses.
24451 2005-09-01 Cyrille Comar <comar@adacore.com>
24452 Gary Dismukes <dismukes@adacore.com>
24453 Ed Schonberg <schonberg@adacore.com>
24454 Javier Miranda <miranda@adacore.com>
24456 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
24458 to check if a type is Constrained in cases related to code generation
24459 (rather than semantic checking) since otherwise we do not generate
24460 similar code for mutable private types depending if their
24461 discriminants are visible or not.
24462 (Check_Abstract_Overriding): Do not complain about failure to override
24463 the primitive operations used in dispatching selects since they will
24464 always be overriden at the freeze point of the type.
24465 (Access_Definition): Separate out handling for resetting the scope
24466 of an anonymous access function result type. Retrieve the scope
24467 of the associated function rather than using Current_Scope, which
24468 does not have a consistent value (depends on whether we're in the
24469 middle of analyzing formal parameters). Add ??? comment about
24470 finding a cleaner way to handle the special cases of scope setting.
24471 (Process_Incomplete_Dependents): A protected operation is never a
24472 dispatching operation (only its wrapper may be).
24473 (Build_Derived_Record_Type): In case of tagged private types that
24474 implement interfaces add derivation of predefined primitive
24476 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
24477 by two parameters that are used in case of derivation from abstract
24478 interface types: No_Predefined_Prims is used to avoid the derivation
24479 of predefined primitives from the interface, and Predefined
24480 Prims_Only is used to complete the derivation predefined primitives
24481 in case of private tagged types implementing interfaces.
24482 Fix typo in comments
24483 (Find_Interface_In_Descendant): Protect the frontend against
24484 wrong code with large circularity chains.
24485 (Is_Private_Overriding): Add support for entities overriding interface
24486 subprograms. The test failed because Entities associated with overriden
24487 interface subprograms are always marked as hidden (and used to build
24488 the secondary dispatch table); in this case the overriden entity is
24489 available through the field abstract_interface_alias (cf. override_
24490 dispatching_operation)
24491 (Access_Definition): Set the scope of the type to Current_Scope for the
24492 case of a function with an anonymous access result type.
24493 (Access_Subprogram_Declaration): Handle creation of the type entity for
24494 an access-to-function type with an anonymous access result.
24495 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
24496 in handling for N_Access_Function_Definition.
24497 (Analyze_Subtype_Declaration): Modify the text of error message.
24498 (Derived_Type_Declaration): Modify the text of error message.
24499 (Process_Subtype): Modify the text of error message plus cleanup
24500 of one redundant error message.
24501 (Analyze_Component_Declaration): Code cleanup.
24502 (Analyze_Object_Declaration): Code cleanup.
24503 (Analyze_Subtype_Declaration): Propagate the null-exclusion
24504 attribute in case of access types. Code cleanup.
24505 (Array_Type_Declaration): Code cleanup.
24506 (Process_Discriminants): Create the new null-excluding itype
24507 if required. Code cleanup.
24508 (Process_Subtype): Create the new null-excluding itype if
24509 required. Code cleanup.
24510 (Build_Derived_Record_Type): Code cleanup to avoid calling
24511 twice the subprogram derive_subprograms in case of private
24512 types that implement interfaces. In this particular case the
24513 subprogram Complete_Subprograms_Derivation already does the
24514 job associated with the second call.
24516 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
24517 conversion to the full view when generating an operation for a
24518 discriminant whose type may currently be private.
24520 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24521 Javier Miranda <miranda@adacore.com>
24523 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
24524 V (Obj.F), the rewriting does not involve the indexed component, but
24525 only the selected component itself.
24526 Do not apply the transformation if the analyzed node is an actual of a
24527 call to another subprogram.
24528 (Complete_Object_Operation): Retain the entity of the
24529 dispatching operation in the selector of the rewritten node. The
24530 entity will be used in the expansion of dispatching selects.
24531 (Analyze_One_Call): Improve location of the error message associated
24533 (Analyze_Selected_Component): No need to resolve prefix when it is a
24534 function call, resolution is done when parent node is resolved, as
24536 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
24537 when attempting to resolve a call transformed from its object notation.
24538 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
24539 of the argument list for each interpretation of the operation.
24540 (Try_Object_Operation): The designated type of an access parameter may
24541 be an incomplete type obtained through a limited_with clause, in which
24542 case the primitive operations of the type are retrieved from its full
24544 (Analyze_Call): If this is an indirect call, and the return type of the
24545 access_to_subprogram is incomplete, use its full view if available.
24547 2005-09-01 Javier Miranda <miranda@adacore.com>
24548 Gary Dismukes <dismukes@adacore.com>
24550 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
24551 access types the null-exclusion and access-to-constant attributes must
24553 (Analyze_Return_Statement): When the result type is an anonymous access
24554 type, apply a conversion of the return expression to the access type
24555 to ensure that appropriate accessibility checks are performed.
24556 (Analyze_Return_Type): For the case of an anonymous access result type,
24557 generate the Itype and set Is_Local_Anonymous_Access on the type.
24558 Add ??? placeholder for check to disallow returning a limited object
24559 in Ada 2005 unless it's an aggregate or a result of a function call.
24560 Change calls from Subtype_Mark to Result_Definition.
24561 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
24562 Result_Definition in call to Make_Function_Specification.
24563 (Build_Body_To_Inline): Change Set_Subtype_Mark to
24564 Set_Result_Definition.
24565 (Make_Inequality_Operator): Change formal Subtype_Mark to
24566 Result_Definition in call to Make_Function_Specification.
24567 (Process_Formals): Create the new null-excluding itype if required.
24568 (New_Overloaded_Entity): For an entity overriding an interface primitive
24569 check if the entity also covers other abstract subprograms in the same
24570 scope. This is required to handle the general case, that is, overriding
24571 other interface primitives and overriding abstract subprograms inherited
24572 from some abstract ancestor type.
24573 (New_Overloaded_Entity): For an overriding entity that comes from
24574 source, note the operation that it overrides.
24575 (Check_Conformance, Type_Conformant): Addition of one new formal
24576 to skip controlling formals in the analysis. This is used to
24577 handle overloading of abstract interfaces.
24578 (Base_Types_Match): Add missing case for types imported from
24579 limited-with clauses
24580 (New_Overloaded_Entity): Add barrier to protect the use of
24581 the "alias" attribute.
24583 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24585 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
24586 verify that the procedure and the entry are mode conformant.
24587 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
24588 as a different operator, which is often a cut-and-paste error.
24590 2005-09-01 Javier Miranda <miranda@adacore.com>
24591 Ed Schonberg <schonberg@adacore.com>
24593 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
24594 used in controlling parameters exclude null because it is necessary to
24595 read the tag to dispatch, and null has no tag.
24596 (Override_Dispatching_Operation): If the previous operation is inherited
24597 from an interface, it becomes hidden and does not participate in later
24600 2005-09-01 Javier Miranda <miranda@adacore.com>
24601 Ed Schonberg <schonberg@adacore.com>
24602 Gary Dismukes <dismukes@adacore.com>
24604 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
24605 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
24606 the expander will generate the corresponding run-time check to evaluate
24608 (Resolve_Call): Check for legal type of procedure name or prefix that
24609 appears as a trigger in a triggering alternative.
24610 (Valid_Conversion): If expression is ambiguous and the context involves
24611 an extension of System, remove System.Address interpretations.
24612 (Resolve_Qualified_Expression): Reject the case of a specific-type
24613 qualification applied to a class-wide argument. Enhance comment
24614 to explain checking of Original_Node.
24615 (Resolve_Type_Conversion): The location of the error message was not
24616 general enough to handle the general case and hence it has been removed.
24617 In addition, this patch improves the text of the message.
24618 (Resolve_Type_Conversion): Add missing support for access to interface
24620 (Resolve_Type_Conversion): If the target is a class-wide interface type,
24621 do not expand if the expression is the actual in a call, because proper
24622 expansion will take place when the call itself is expanded.
24623 (Resolve_Allocator): If the context is an unchecked conversion, the
24624 allocator inherits its storage pool, if any, from the target type of
24627 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24628 Javier Miranda <miranda@adacore.com>
24630 * sem_type.adb (Add_One_Interp): If a candidate operation is an
24631 inherited interface operation that has an implementation, use the
24632 implementation to avoid spurious ambiguities.
24633 (Interface_Present_In_Ancestor): In case of concurrent types we can't
24634 use the Corresponding_Record_Typ attribute to look for the interface
24635 because it is set by the expander (and hence it is not always
24636 available). For this reason we traverse the list of interfaces
24637 (available in the parent of the concurrent type).
24638 (Interface_Present_In_Ancestor): Handle entities from the limited view
24640 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24642 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
24643 from the list of required components.
24644 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
24645 primitive procedure of a limited interface with a controlling first
24647 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
24649 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
24650 capture if it is generated in the second operand of a short-circuit
24652 Do not capture values for variables with address clauses.
24653 (Is_Object_Reference): Treat a function call as an object reference only
24654 if its type is not Standard_Void_Type.
24656 2005-09-01 Ed Schonberg <schonberg@adacore.com>
24658 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
24659 to a variable that is statically known to be constant.

24671 Document that bounds of result of Base_Name match the input index
24673 Add documentation on environment variable syntax for Expand_Path
24675 * gnat_ugn.texi: Update documentation to include mention of -m switches
24676 Document new treatment of wide characters in max line length
24678 Remove -gnatL/-gnatZ switches, no longer used.
24679 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
24682 * gnat_rm.texi: Add doc for two argument form of pragma
24683 Float_Representation.
24684 Add documentation for pragma No_Strict_Aliasing
24685 Add note that explicit component clause overrides pragma Pack.
24686 Add documentation of pragma Debug_Policy

25441 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
25442 longer protected objects. They have been replaced by lower-level
25443 suspension objects made up by a mutex and a condition variable (or
25444 their equivalent given a particular OS) plus some internal data to
25445 reflect the state of the suspension object.
25446 (Initialize, Finalize): Add this initialization procedure for
25447 Suspension_Object, which is a controlled type.
25448 (Finalize): Add the finalization procedure for Suspension_Object,
25449 which is a controlled type.
25451 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
25452 Ada.Synchronous_Task_Control because there is no longer a need for a
25453 VxWorks specific version of this package. Target dependencies
25454 has been moved to System.Task_Primitives.Operations.
25456 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
25458 (InitializeCriticalSection, EnterCriticalSection,
25459 LeaveCriticalSection, DeleteCriticalSection): Replace the type
25460 pCriticalSection by an anonymous access type so that we avoid problems
25461 of accessibility to local objects.
25463 * s-taprop.ads, s-taprop-posix.adb, s-taprop-vxworks.adb,

25467 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
25468 set the environment task mask here.
25469 (Current_State): Add this function that returns the state of the
25471 (Set_False): Add this procedure that sets the state of the suspension
25473 (Set_True): Add this procedure that sets the state of the suspension
25474 object to True, releasing the task that was suspended, if any.
25475 (Suspend_Until_True): Add this procedure that blocks the calling task
25476 until the state of the object is True. Program_Error is raised if
25477 another task is already waiting on that suspension object.
25478 (Initialize): Add this procedure for initializing the suspension
25479 object. It initializes the mutex and the condition variable which are
25480 used for synchronization and queuing, and it sets the internal state

25952 (Resolve_Actuals): Enable full error reporting on view conversions
25953 between unrelated by_reference array types.
25954 The rule for view conversions of arrays with aliased components is

25997 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
25998 both bound checks, rather than a conjunction.
25999 (Insert_Valid_Check): If the expression is an actual that is an indexed
26000 component of a bit-packed array, force expansion of the packed element
26001 reference, because it is specifically inhibited elsewhere.

26014 may be deallocated by Normalize_Arguments.
26015 (Collect_Arguments): Eliminate empty arguments
26017 * gnatcmd.adb (All_Projects): New Boolean flag, initialized to False,
26018 and set to True when -U is used for GNAT PRETTY or GNAT METRIC.

26968 To_Any and TypeCode TSSs on RAS types directly using Set_TSS, instead
26969 of using Set_Renaming_TSS. This ensures that the TSS bodies are not
26970 analyzed if expansion is disabled (which could otherwise cause spurious
26971 error messages if expansion has been disabled due to previous
26972 (unrelated) errors).
26974 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
26975 is disabled, the entity denoted by the argument is the access type
26976 itself, not an underlying record type, so there is no need to go back
26977 to the Corresponding_Remote_Type.

26987 denotes a type in the class.
26988 (Expand_Intrinsic_Call): Call Expand_Dispatching_Constructor in the case
26989 of Name_Generic_Dispatching_Constructor.
26991 * Makefile.rtl: Add a-tgdico.ads to the list of library units (new Ada

27009 a class-wide stream attribute) and then rewrite the attribute name
27010 as the name of the appropriate compiler-generated stream primitive.

27022 itype whose parent is controlled and not yet frozen, do not create a
27023 freeze node for the itype if expansion is disabled.
27025 2005-03-29 Vincent Celier <celier@adacore.com>
27027 * make.adb (Gnatmake): Don't fail if the main project file is declared
27028 as having no Ada sources. Do not display message "no sources to

27049 * par-ch4.adb (P_Name): When a bad attribute is returned, return error,
27050 rather than proceed ahead using a junk attribute name.
27052 2005-03-29 Vincent Celier <celier@adacore.com>
27054 * prj.ads, prj.adb: (Project_Data): Add new component Display_Name
27056 * prj-part.adb (Parse_Single_Project): Set the location of a project
27057 on its defining identifier, rather than on the reserved word "project".
27059 * prj-proc.adb (Expression): Adapt to the fact that default of external
27060 references may be string expressions, not always literal strings.
27061 (Recursive_Process): Set Display_Name equal to Name
27062 when Location is No_Location, that is when there is no actual file.
27063 Get the Display_Name of the project from the source, when it is not a
27065 (Process): Use the Display_Name in error messages
27067 * prj-strt.adb (External_Reference): Allow default to be string
27068 expressions, not only literal strings.

27092 * sem_ch4.adb (Analyze_Selected_Component): Do not generate an actual
27093 subtype if code is being pre-analyzed, to prevent un-expanded
27094 references to protected formals, among others.
27095 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
27096 interpretation that can be a call, include the result of the call as a
27097 possible interpretation of the dereference.
27099 * sem_ch5.adb (Process_Bounds): Determine type of range by
27100 pre-analyzing a copy of the original range, and then analyze the range
27101 with the expected type.
27103 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference
27104 with an overloaded prefix where not all interpretations yield an
27105 access to subprogram, do not rewrite node as a call.
27106 (Resolve_Explicit_Dereference): Recognize the previous case and rewrite
27107 the node as a call once the context identifies the interpretation of
27108 the prefix whose call yields the context type.
27109 (Valid_Conversion): For the case of a conversion between
27110 local access-to-subprogram types, check subtype conformance using
27111 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more

27116 * sem_ch6.adb (Set_Formal_Mode): If the subtype has a non_null
27117 indicator, indicate that the formal can never be null.
27118 (Process_Formals): If a formal has a non_null indicator, insert the
27119 resulting subtype immediately before the enclosing subprogram decl,
27120 and not at the beginning of the corresponding declarative part, to
27121 prevent access before elaboration (Ada2005).

27244 explanatory error message (including the name of the missing attribute).
27245 (Stream_Operation_OK): Renamed from Stream_Operations_OK. This
27246 subprogram determines whether a default implementation exists for a
27247 given stream attribute.
27248 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies):
27249 Determine whether to generate a default implementation for each stream
27250 attribute separately, as this depends on the specific attribute.

27253 limited extension where a stream attribute is missing for a limited
27254 component (which will have been flagged in Exp_Ch3.Sem_Attr), do not

27832 * checks.adb (Get_E_First_Or_Last): When the expression being retrieved
27833 is an N_Raise_Constraint_Error node, create a new copy of it without
27834 going through a call to Duplicate_Subexpr.
27836 2005-03-15 Eric Botcazou <ebotcazou@adacore.com>
27837 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27838 Nicolas Setton <setton@adacore.com>
27839 Ed Schonberg <schonberg@adacore.com>
27845 * decl.c (gnat_to_gnu_field): Reject aliased components with a
27846 representation clause that prescribes a size not equal to the rounded
27847 size of their types.
27848 (gnat_to_gnu_entity, case E_Component): Always look at
27849 Original_Record_Component if Present and not the entity.
27850 (gnat_to_gnu_entity, case E_Record_Subtype): Rework handling of subtypes
27851 of tagged extension types by not making field for components that are
27853 (gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
27854 (gnat_to_gnu_entity) <E_Variable>: Do not convert again the
27855 expression to the type of the object when the object is constant.
27856 Reverse defer_debug_incomplete_list before traversing it, so that trees
27857 are processed in the order at which they were added to the list. This
27858 order is important when using the stabs debug format.
27859 If we are deferring the output of debug information, also defer this
27860 output for a function return type.
27861 When adding fields to a record, prevent emitting debug information
27862 for incomplete records, emit the information only when the record is
27864 (components_to_record): New parameter defer_debug.
27865 (gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.
27866 (gnat_to_gnu_field_decl): New function.
27867 (substitution_list, annotate_rep): Call it.
27868 (gnat_to_gnu_entity, case E_Record_Subtype): Likewise.
27869 (gnat_to_gnu_entity, case E_Record_Type): Likewise.
27870 No longer update discriminants to not be a COMPONENT_REF.
27871 (copy_alias_set): Strip padding from input type; also handle
27872 unconstrained arrays properly.
27874 * gigi.h (write_record_type_debug_info): New function.
27875 Convert to use ANSI-style prototypes. Remove unused
27876 declarations for emit_stack_check, elab_all_gnat and
27877 set_second_error_entity.
27878 (gnat_to_gnu_field_decl): New decl.
27880 * utils.c (write_record_type_debug_info): New function.
27881 (finish_record_type): Delegate generation of debug information to
27882 write_record_type_debug_info.
27883 (update_pointer_to): Remove unneeded calls to rest_of_decl_compilation.
27884 (update_pointer_to): Fix pasto.
27885 (convert) <UNION_TYPE>: Accept slight type variations when
27886 converting to an unchecked union type.
27888 * exp_ch13.adb (Expand_N_Freeze_Entity): If Freeze_Type returns True,
27889 replace the N_Freeze_Entity with a null statement.
27891 * freeze.adb (Freeze_Expression): If the freeze nodes are generated
27892 within a constrained subcomponent of an enclosing record, place the
27893 freeze nodes in the scope stack entry for the enclosing record.
27894 (Undelay_Type): New Subprogram.
27895 (Set_Small_Size): Pass T, the type to modify; all callers changed.
27896 (Freeze_Entity, Freeze_Record_Type): Change the way we handle types
27897 within records; allow them to have freeze nodes if their base types
27900 * exp_util.adb (Remove_Side_Effects): Properly test for
27901 Expansion_Delayed and handle case when it's inside an
27902 N_Qualified_Expression.
27904 * sem_ch3.adb (Derived_Type_Declaration): New predicate
27905 Comes_From_Generic, to recognize accurately that the parent type in a
27906 derived type declaration can be traced back to a formal type, because
27907 it is one or is derived from one, or because its completion is derived
27909 (Constrain_Component_Type): If component comes from source and has no
27910 explicit constraint, no need to constrain in in a subtype of the
27912 (Constrain_Access, Constrain_Array): Allow itypes to be delayed.
27913 Minor change to propagate Is_Ada_2005 flag
27915 * trans.c (gnat_to_gnu, case N_Aggregate): Verify that
27916 Expansion_Delayed is False.
27917 (assoc_to_constructor): Ignore fields that have a
27918 Corresponding_Discriminant.
27919 (gnat_to_gnu) <N_Return_Statement>: Restructure. If the
27920 function returns "by target", dereference the target pointer using the
27921 type of the actual return value.
27922 <all>: Be prepared for a null gnu_result.
27923 (processed_inline_subprograms): Check flag_really_no_inline
27924 instead of flag_no_inline.
27925 (set_second_error_entity): Remove unused function.
27926 (gnat_to_gnu, case N_Selected_Component): Call
27927 gnat_to_gnu_field_decl.
27928 (assoc_to_constructor): Likewise.
27930 2005-03-15 Robert Dewar <dewar@adacore.com>
27931 Ed Schonberg <schonberg@adacore.com>
27932 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
27934 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
27935 Must_Be_Byte_Aligned for cases where we do not need to use a
27936 System.Pack_nn unit.
27938 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
27940 Needed now that we do some processing for IN parameters as well. This
27941 may well fix some unrelated errors.
27942 (Expand_Call): Handle case of unaligned objects (in particular those
27943 that come from packed arrays).
27944 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
27945 renamed entity is an inherited operation, re-expand the call using the
27946 original operation, which is the one to call.
27947 Detect attempt to inline parameterless recursive subprogram.
27948 (Represented_As_Scalar): Fix to work properly with private types
27949 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
27950 accurate estimate. Yields True in far fewer cases than before,
27951 improving the quality of code that depends on this test.
27953 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
27954 over both visible and private declarations to remove them from tree,
27955 and mark subprograms declared in package as eliminated, to prevent
27956 spurious use in subsequent compilation of generic units in the context.
27958 * exp_util.ads: Minor cleanup in variable names
27960 * sem_eval.ads, sem_eval.adb: Minor reformatting
27961 (Compile_Time_Known_Bounds): New function
27963 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27965 * exp_ch7.adb (Convert_View): Use base types of underlying types when
27966 determining whether an unchecked conversion is needed for the argument
27967 of an initialization call.
27969 2005-03-15 Ed Schonberg <schonberg@adacore.com>
27971 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
27972 that appears in the instantiation rather than the internal subtype
27973 generated in the wrapper package, to avoid anomalies in gigi when the
27974 target is derived from a private type whose full view is an access type.
27976 2005-03-15 Robert Dewar <dewar@adacore.com>
27978 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
27980 Add documentation to replace the use of this flag
27981 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
27984 2005-03-15 Thomas Quinot <quinot@adacore.com>
27986 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
27987 here from exp_attr so it can be shared between exp_attr and exp_dist.
27988 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
27989 all TSS names, not a subset thereof, and the previous name introduced
27990 an unnecessarily confusion that a distinction might exist between
27991 "OK" TSS names and some "not OK" TSS names.
27993 2005-03-15 Doug Rupp <rupp@adacore.com>
27995 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
27998 2005-03-15 Pascal Obry <obry@adacore.com>
27999 Eric Botcazou <ebotcazou@adacore.com>
28003 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
28004 when IN_RTS. This is to work around a bootstrap path problem.
28006 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
28007 table and pass it to __gnat_install_SEH_handler().
28008 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
28010 * lang.opt: Fix specification of -fRTS=.
28012 2005-03-15 Doug Rupp <rupp@adacore.com>
28013 Bernard Banner <banner@adacore.com>
28014 Vincent Celier <celier@adacore.com>
28015 Arnaud Charlet <charlet@adacore.com>
28018 This change works fine when gnatlib is built from the gcc directory,
28019 but does not work when using the libada Makefile, since GCC_FOR_TARGET
28020 is not passed to ada/Makefile.in, so more work is needed by a
28021 Makefile/configure expert.
28023 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
28024 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
28025 Setup gnatlink switch -M for x86_64 linux, as it is already setup
28027 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
28028 Run ranlib on libgccprefix.a
28029 Define PREFIX_OBJS for Darwin, to build libgccprefix.
28030 (ADA_INCLUDE_SRCS): Split Ada packages.
28032 2005-03-15 Robert Dewar <dewar@adacore.com>
28034 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
28036 * impunit.adb: Add GNAT.UTF_32
28038 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
28040 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
28041 now uses GNAT.UTF_32).
28043 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
28044 capabilities for categorizing characters using Unicode categories
28046 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28048 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
28049 instantiation that has been rewritten as a package body, retrieve spec
28050 to generate proper name for implicit_with_clause.
28051 (Install_Parents): Recognize a parent that is an instantiation but has
28052 been rewritten as a package declaration during analysis.
28054 2005-03-15 Javier Miranda <miranda@adacore.com>
28055 Ed Schonberg <schonberg@adacore.com>
28057 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
28058 parameter reported some error we immediately return. This improves the
28059 behaviour of the frontend in case of errors.
28060 (Install_Parent, Remove_Parent): Introduce new flag
28061 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
28062 ancestor of a generic child unit, when the child is being instantiated.
28063 (Inline_Instance_Body): If we are compiling the private
28064 part or the body of a child unit, restore the proper visibility of the
28065 parents after compiling the instance body.
28067 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28068 Javier Miranda <miranda@adacore.com>
28071 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
28072 of a private type, in which case it is underlying_type that denotes
28073 the proper task. Also modified to use the new entity attribute
28074 that is directly available in the task type and task subtype entities
28075 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
28076 arrays when other dimensions than the first are constrained by
28077 discriminants of an enclosing record.
28078 (Insert_Explicit_Dereference): If the prefix is an indexed component or
28079 a combination of indexed and selected components, find ultimate entity
28080 and generate the appropriate reference for it, to suppress spurious
28082 (Note_Possible_Modification): If an entity name has no entity, return.
28083 (Is_Variable): A function call never denotes a variable.
28084 (Requires_Transient_Scope): For record types, recurse only on
28085 components, not on internal subtypes that may have been generated for
28086 constrained components.
28088 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28090 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
28091 Eliminated as candidates for resolution. Both efficient, and avoids
28092 anomalies with operators declared in deleted code.
28093 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
28094 expansion is disabled (as when compiling a generic) to prevent spurious
28095 warnings on prefixes of selected components.
28097 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28099 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
28100 attached to a list before checking whether it appears in the private
28101 declarations of the current package.
28102 (Make_Inequality_Operator): Insert declaration in proper declarative
28103 list rather than just setting the Parent field, so that
28104 Is_Private_Declaration can handle it properly.
28106 2005-03-15 Ed Schonberg <schonberg@adacore.com>
28108 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
28109 a renaming a body, check that the renamed subprogram in not intrinsic.
28110 (Find_Direct_Name): If several use_visible entities hide
28111 each other, and the context is a predefined file compiled through
28112 rtsfind, keep only the entity that comes from a predefined file.
28114 2005-03-15 Geert Bosch <bosch@adacore.com>
28116 * s-fatgen.adb (Valid): Extend special exceptions to account for long
28117 long float padding to also cover AMD64 and IA64.
28119 2005-03-15 Gary Dismukes <dismukes@adacore.com>
28121 * s-imgwch.adb: Add with and use of Interfaces.
28122 (Img_Wide_Character): Change type of Val to Unsigned_16.
28123 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
28125 2005-03-15 Matthew Gingell <gingell@adacore.com>
28127 * sysdep.c: Implement __gnat_localtime_r as call to localtime_r on AIX.
28129 2005-03-15 Robert Dewar <dewar@adacore.com>

28133 * sem_ch7.adb: Minor change to propagate Is_Ada_2005 flag
28135 * i-c.adb: Clarify that AI-258 behavior is also intended in Ada 95
28137 2005-03-15 Robert Dewar <dewar@adacore.com>
28139 * s-bitops.adb, s-bitops.ads,
28140 s-taprop-os2.adb, s-intman-vms.ads, s-intman-vxworks.ads,

28161 procedures in the bug boxes for various GNAT builds.
28163 2005-03-15 Vincent Celier <celier@adacore.com>
28165 * snames.ads, snames.adb: Save as Unix text file, not as DOS text file
28167 2005-03-15 Geert Bosch <bosch@adacore.com>
28168 Arnaud Charlet <charlet@adacore.com>
28169 Robert Dewar <dewar@adacore.com>
28170 Cyrille Comar <comar@adacore.com>
28171 Sergey Rybin <rybin@adacore.com>
28173 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
28174 too specific and long-winded to be appropriate for the GNAT User's
28176 Warn about use of GCC switches not documented in the GNAT User's Guide,
28177 as these may cause generated code to not conform to Ada semantics.
28178 Remove mention of -gdwarf-2 for sparc64, since this is now the default.
28179 Add documentation for -gnat95 and -gnat05 switches
28180 Remove paragraph documenting obsolete way to refer to third party
28182 Add a few references to Ada_05 that were missing.
28183 Update documentation on -gnatZ/-gnatL.

28228 we asked for an unknown mode.
28230 2005-02-12 Richard Henderson <rth@redhat.com>
28232 * utils.c (gnat_type_for_mode): Return NULL for COMPLEX modes;

28305 * exp_ch3.ads, exp_ch3.adb: Fix various places where Wide_Wide_String
28306 was not taken into account.

28599 the formal subprogram.
28600 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
28601 which is an unclean use of that field, we set the new field

28620 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
28621 mark in function specification, in a context where the formals are
28622 visible and hide outer homographs.
28624 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
28625 as the tagged type for the cases of abstract formal subprograms and
28626 renamings of those. Clean up spec comments.

28628 procedure", covering the case of a call to a formal abstract procedure
28629 that has statically tagged operands.
28630 (Check_Dispatching_Call): Check for the case of an actual given by
28631 a tag-indeterminate function call whose type is an ancestor of the

28739 component of an array of arrays in an assignment context, and the
28740 aggregate has component associations that require sliding on

28827 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
28828 with expansion disabled. The actual subtype is needed among other
28829 places when the selected component appears in the context of a loop
28830 bound, and denotes a packed array.
28831 (Operator_Check): Always use the first subtype in the
28832 error message, to avoid the appearance of internal base types.
28833 (Transform_Object_Operation): Copy each actual in full
28834 to the parameter associations of the constructed call, rather than
28835 using the shallow copy mechanism of New_Copy_List. This ensures that
28836 the chaining of named associations is done properly.
28837 (Complete_Object_Operation): Rewrite node, rather than
28838 replacing it, so that we can trace back to the original selected
28841 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
28842 and calls that use object notation, if the called function is not
28843 declared in a withed unit, place the elaboration constraint on the
28844 unit in the context that makes the function accessible.
28845 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
28846 imposes an elaboration constraint between two packages.
28848 2005-02-09 Ed Schonberg <schonberg@adacore.com>
28850 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
28851 views of a private type after handling its private dependents, to
28852 maintain proper stack discipline between entry and exit from the
28855 2005-02-09 Cyrille Comar <comar@adacore.com>

28873 Slight fix to documentation of -gnaty with no parameters
28875 * xr_tabls.ads: Add ??? comment for missing overall comment
28877 * xsinfo.adb: Make default file name be sinfo.h, since this is what
28878 we now use by default.
28880 * xsnames.adb: Adjust end of file test to look for five space followed
28881 by '#' instead of six spaces. The format of xsnames.adb was modified
28882 in the last update.
28884 * a-numeri.ads: Add reference to AI-388 for greek letter pi
28887 * clean.adb: Minor reformatting.
28889 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
28890 gnatname.adb: Minor reformatting

28893 * csets.adb: Eliminate obsolete comment
28895 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
28898 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
28900 2005-02-09 Sergey Rybin <rybin@adacore.com>
28902 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
28903 the difference between compact and incompact layout and add the record
28904 representation clause to the example illustrating different layouts.
28905 Add the description of '-A5' gnatpp option ("align 'AT' keywords in
28906 component clauses").
28908 2005-02-09 Florian Villoing <villoing@adacore.com>
28910 * gnat_ugn.texi: Fix typos.
28911 Use @command to display 'gcc', 'gnatbind', etc. insted of @code or

28914 in the generated documentation.
28916 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28918 * gnat_ugn.texi: Remove all mentions of FSU threads, which are no

28960 2005-02-09 Arnaud Charlet <charlet@adacore.com>
28962 * s-taprop.ads (Initialize): Update comments. Remove pragma Inline,

29210 2005-01-03 Olivier Hainque <hainque@adacore.com>
29212 * decl.c (compatible_signatures_p): New function. The intended purpose
29213 is to check if two function signatures for a call-site and a callee are
29214 compatible enough for the call to be valid. The underlying purpose is
29215 to check if a call to a mapped builtin is using the right interface.
29216 The current code actually does not check antyhing - this a placeholder
29217 for future refinements.

29759 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
29760 is a non-overloaded implicit dereference, call the above subprogram to
29761 ensure proper recording of references.
29763 2004-12-07 Gary Dismukes <dismukes@adacore.com>

29783 address that has no record in the system hosts database and no reverse
29786 * cstand.adb, a-tags.ads: Fix typos in comment.
29788 2004-12-07 Robert Dewar <dewar@adacore.com>
29790 * exp_ch2.adb, exp_ch3.adb, exp_ch5.adb, exp_ch8.adb,
29791 exp_ch9.adb, exp_pakd.adb, interfac.ads, sem_ch6.adb,
29792 sem_ch7.adb, sem_ch10.adb, sem_ch13.adb, sem_ch3.adb,

29796 Add some ??? comments asking for more comments
29798 * s-poosiz.adb: Minor reformatting
29799 Add comments on alignment requirement
29801 * sinfo.ads: Remove obsolete comment and fix typo.
29803 2004-12-07 Vincent Celier <celier@adacore.com>
29804 Sergey Rybin <rybin@adacore.com>
29806 * gnat_ugn.texi: Update the section "The GNAT Driver and Project
29807 Files" with the new tool and package names.
29808 Reformatting to suppress most of the warnings for line too long
29809 Document the new section "Project Search Path:" in the output of
29811 Add gnatmetric section
29813 2004-12-07 Vincent Celier <celier@adacore.com>
29815 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
29816 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
29817 and -eit to -ept. Added qualifier
29818 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
29820 2004-11-27 Andreas Schwab <schwab@suse.de>
29822 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
29824 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29826 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
29827 internal implementation unit GNAT.Sockets.Thin,
29828 as their usage for sockets is non-portable (using the read and write
29829 functions from the system runtime library is fine on UNIX but won't
29830 work under Windows).
29832 * mingw32.h: Update copyright notice.
29834 2004-11-25 Arnaud Charlet <charlet@adacore.com>
29836 * ada-tree.h: Minor reformatting of previous change to avoid lines
29837 longer than 79 characters.
29839 2004-11-25 Olivier Hainque <hainque@adacore.com>
29841 * tb-gcc.c: GCC infrastructure based implementation of

29855 2004-11-21 Andreas Jaeger <aj@suse.de>
29857 * stylesw.adb: Change Style_Check_Subprogram_Order to
29858 Style_Check_Order_Subprograms.
29860 2004-11-18 Arnaud Charlet <charlet@adacore.com>
29862 * adaint.h, adaint.c
29863 (__gnat_portable_spawn): Fix cast of spawnvp third parameter
29865 Add also a cast to kill another warning.
29866 (win32_no_block_spawn): Initialize CreateProcess's dwCreationFlags
29867 parameter with the priority class of the parent process instead of
29868 always using the NORMAL_PRIORITY_CLASS.
29869 (__gnat_dup): New function.
29870 (__gnat_dup2): New function.
29871 (__gnat_is_symbolic_link): Enable the effective body of this
29872 function when __APPLE__ is defined.
29874 * g-os_lib.ads, g-os_lib.adb (Spawn): Two new procedures.
29877 2004-11-18 Olivier Hainque <hainque@adacore.com>
29879 * a-exexpr.adb (Others_Value, All_Others_Value): New variables, the
29880 address of which may be used to represent "others" and "all others"
29881 choices in exception tables, instead of the current harcoded
29882 (void *)0 and (void *)1.
29883 (Setup_Exception): Do nothing in the GNAT SJLJ case.
29885 * gigi.h (others_decl, all_others_decl): New decls representing the
29886 new Others_Value and All_Others_Value objects.
29887 (struct attrib): Rename "arg" component as "args", since GCC expects a
29888 list of arguments in there.
29890 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
29891 corresponding objects exported by a-exexpr, instead of hardcoded dummy
29894 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
29895 others_decl and all_others_decl instead of hardcoded dummy addresses
29896 to represent "others" and "all others" choices, which is cleaner and
29897 more flexible with respect to the possible eh pointer encoding policies.
29899 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
29900 (process_attributes): Account for the naming change of the "args"
29901 attribute list entry component.
29903 * decl.c (build_attr_list): Rename into prepend_attributes to allow
29904 cumulating attributes for different entities into a single list.
29905 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
29906 attributes for the current entity and propagate first subtype
29907 attributes to other subtypes.
29908 <E_Procedure>: Attribute arguments are attr->args and not
29909 attr->arg any more.
29910 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
29911 argument provided, as this is what GCC expects. Use NULL_TREE instead
29914 2004-11-18 Robert Dewar <dewar@adacore.com>
29916 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
29917 Minor reformatting througout (including new function specs)
29918 Add ??? comments asking for clarification.
29920 2004-11-18 Thomas Quinot <quinot@adacore.com>
29922 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
29923 incomplete duplicate implementation of this subprogram from butil.
29925 2004-11-18 Thomas Quinot <quinot@adacore.com>
29927 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
29928 procedures factors the common processing for building an RPC receiver
29929 for an RCI package or an RACW type.
29930 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
29931 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
29932 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
29934 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
29936 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
29938 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
29939 distribution subprogram identifiers that are either subprogram numbers
29941 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
29942 string distribution identifiers assigned to a given subprogram.
29943 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
29944 (Add_RAS_Dereference_TSS): Add comments.
29945 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
29946 is not referenced yet because it will be used by the PolyORB DSA
29948 (Insert_Partition_Check): Remove fossile code.
29949 (First_RCI_Subprogram_Id): Document this constant.
29950 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
29952 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
29953 replaced with calls to Get_Library_Unit_Name_String. Previously there
29954 were several instances of the same code in different locations in the
29955 compiler; this checkin completes the replacement of all of these
29956 instances with calls to a common subprogram.
29957 Minor reformatting.
29959 * sem_dist.adb: Remove comment noting that RPC receiver generation
29960 should be disabled for RACWs that implement RASs.
29961 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
29963 * sem_util.ads, sem_util.adb (Has_Stream): New function
29964 (Get_Library_Unit_Name_String): New subprogram to retrieve the fully
29965 qualified name of a library unit into the name buffer.
29966 (Note_Possible_Modification): Generate a reference only
29967 if the context comes from source.
29969 * snames.ads (PCS_Names): New subtype corresponding to names of
29970 supported implementations of the Partition Communication Subsystem
29971 (PCS) (i.e. the runtime library support modules for the distributed
29974 2004-11-18 Robert Dewar <dewar@adacore.com>

29981 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
29983 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
29985 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
29986 (Expand_Pragma_Psect_Object): New procedure
29987 These procedures contain the revised and cleaned up processing for
29988 these two pragmas. This processing was formerly in Sem_Prag, but
29989 is more appropriately moved here. The cleanup involves making sure
29990 that the pragmas are properly attached to the tree, and that no
29991 nodes are improperly shared.
29993 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
29994 pragmas to Exp_Prag, which is more appropriate.
29995 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
29996 check for duplicates Remove use of Is_Psected flag, no longer needed.
29997 Use new Make_String_Literal function with string.
29999 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
30000 that are functions return universal values, that have to be converted
30001 to the context type.
30002 Use new Make_String_Literal function with string.
30003 (Get_Stream_Convert_Pragma): New function, replaces the use of
30004 Get_Rep_Pragma, which had to be kludged to work in this case.
30006 * freeze.adb: Use new Has_Rep_Pragma function
30008 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
30009 function with string.
30010 Use new Has_Rep_Pragma function.
30012 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
30015 2004-11-18 Robert Dewar <dewar@adacore.com>
30017 * errout.ads, errout.adb: (First_Sloc): New function
30019 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
30020 check (-gnatyx) instead of being included as a redundant construct
30023 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
30024 Style_Check_Order_Subprograms.
30026 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
30027 stylesw.adb: Add Style_Check_Xtra_Parens
30029 * usage.adb: Add line for -gnatyx (check extra parens)
30031 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
30033 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30034 Robert Dewar <dewar@adacore.com>
30036 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
30037 discriminant of a constrained subtype, analyze the copy of the
30038 corresponding constraint, because in some cases it may be only
30039 partially analyzed.
30040 Removes long-lived ??? comments.
30042 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
30043 handled controlled or secondary-stack expressions within the
30044 iteration_scheme of a loop.
30046 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
30047 bounds that may contain functions calls, to prevent memory leaks when
30048 the bound contains a call to a function that uses the secondary stack.
30049 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
30050 generate temporaries for loop bounds that might contain function calls
30051 that require secondary stack and/or finalization actions.
30053 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
30054 selected component and the selector is overloadable (not just a
30055 function) treat as function call, Analyze_Call will disambiguate if
30057 (Analyze_Selected_Component): Do not generate an actual subtype for the
30058 selected component if expansion is disabled. The actual subtype is only
30059 needed for constraint checks.
30060 (Analyze_Allocator): If restriction No_Streams is set, then do
30061 not permit objects to be declared of a stream type, or of a
30062 composite type containing a stream.
30064 * restrict.ads: Remove the a-stream entry from Unit_Array, since
30065 No_Streams no longer prohibits with'ing this package.
30067 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
30068 discriminants, but the parent base has unknown discriminants, there is
30069 no discriminant constraint to inherit. Such a discrepancy can arise
30070 when the actual for a formal type with unknown discriminants is a
30071 similar private type whose full view has discriminants.
30072 (Analyze_Object_Declaration): If restriction No_Streams is set, then
30073 do not permit objects to be declared of a stream type, or of a
30074 composite type containing a stream.
30076 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30078 * exp_dbug.ads: Update documentation to reflect simpler encoding for
30079 protected operations.
30081 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
30082 generated name, it complicates decoding in gdb and hinders debugging
30083 of protected operations.
30084 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
30085 flag for the protected entry barrier function.
30086 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
30087 flag for the protected entry function.
30089 2004-11-18 Nicolas Setton <setton@adacore.com>
30091 * expect.c: Define __unix__ when __APPLE__ is defined.
30093 * Makefile.in: Inform the value of the variable GMEM_LIB in the
30094 Darwin-specific section.
30096 * lang-specs.h: Change the placement of the %1 marker.
30097 Works around the fact that gcc adds -fPIC by default under Darwin.
30099 2004-11-18 Ed Schonberg <schonberg@adacore.com>
30101 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
30102 type of the object with the packed array type, set the Analyzed flag
30103 on the object if it is an entity or simple indexed component, to avoid
30104 spurious type errors.
30106 2004-11-18 Gary Dismukes <dismukes@adacore.com>
30108 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
30109 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
30110 separate line from the version message.
30112 2004-11-18 Ed Falis <falis@adacore.com>
30114 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
30116 (init_float): Eliminate initialization of floating point status for
30117 AE653. The instructions have no effect for vThreads.
30119 2004-11-18 Vincent Celier <celier@adacore.com>
30121 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
30122 gnatbind is invoked with -shared.
30124 2004-11-18 Jose Ruiz <ruiz@adacore.com>
30126 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
30127 for Detect_Blocking which is redundant with the check done within the
30128 procedure Protected_Single_Entry_Call.
30129 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
30130 Detect_Blocking which is redundant with the check done within the
30131 procedure Protected_Single_Entry_Call.
30133 2004-11-18 Vincent Celier <celier@adacore.com>
30135 * makegpr.adb (Compile): Put the compiling switches (in package
30136 Compiler and on the command line) immediately after "-c", instead of
30137 at the end of the command line invocation of the compiler, when
30138 compiling a non-Ada file.
30139 (Build_Global_Archive): When there is no need to rebuild the archive,
30140 set Global_Archive_Exists, so that the archive is passed to the linker
30143 2004-11-18 Robert Dewar <dewar@adacore.com>
30144 Sergey Rybin <rybin@adacore.com>
30147 Remove extra paren check from list of checks for redundant constructs
30148 Add documentation of new -gnatyx style check (check extra parens)
30149 Remove paragraph about gnatelim debug options.
30151 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
30152 objects rather than forbidding dependencies on the package Ada.Streams.
30154 * sinfo.ads: Add ??? note that we should document pragmas passed to
30157 * g-expect.ads: Fix a few typos in the comments.
30159 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
30161 * misc.c (gnat_handle_option): Use %< and %> for quoting in
30164 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
30166 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
30168 2004-11-07 Andreas Schwab <schwab@suse.de>
30170 * Makefile.in (install-gnatlib): Remove spurious hyphen.
30172 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
30175 * Makefile.in (darwin): Set soext to .dylib.
30177 2004-10-26 Vincent Celier <celier@gnat.com>
30178 Thomas Quinot <quinot@act-europe.fr>
30180 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
30181 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
30182 there is no use of GNAT.Sockets.Constants.
30183 Remove remaining pragma Import for C_Write
30184 Remove C_Read and C_Write from internal implementation unit
30185 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
30186 the read and write functions from the system runtime library is fine
30187 on UNIX but won't work under Windows).
30189 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
30190 (Check_Selector): Use C_Recv instead of C_Read.
30191 Selectors are the GNAT.Sockets abstraction to perform a select()
30192 call on a set of descriptors. To allow abortion of an ongoing
30193 select operation, some data is written to a dedicated socket that
30194 is always monitored.
30195 Under Windows, the write and read library functions cannot operate
30196 on sockets, so we need to use send and recv instead, which is portable
30197 across all supported platforms.
30199 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
30200 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
30201 (using the read and write functions from the system runtime library is
30202 fine on UNIX but won't work under Windows).
30204 2004-10-26 Nicolas Setton <setton@act-europe.fr>
30206 * mlib-tgt-darwin.adb: New file.
30208 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30209 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30210 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
30211 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
30214 * Makefile.in: Add support for building shared libraries under Darwin.
30215 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
30216 the low level EH init subprogram to be called from __gnat_initialize.
30218 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
30219 indicates which options to pass to the archive indexer.
30221 * mlib-utl.adb: Add support for calling ranlib with additional
30222 options. This is needed for instance under Mac OS X.
30223 (Ranlib_Options): New global variable, used to store the potential
30224 options to pass to ranlib.
30225 (Ar): Use Ranlib_Options when spawning ranlib.
30226 (Initialize): Set the value of ranlib option.
30228 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30230 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
30231 instead of 8K, to reflect the real potential needs for stack-checking
30234 2004-10-26 Pascal Obry <obry@gnat.com>
30236 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
30238 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
30239 Windows only the initial thread stack size can be set so it is good to
30240 start we a low stack size.
30241 The OS will adjust the size as needed.
30243 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
30244 Nicolas Setton <setton@act-europe.fr>
30246 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
30247 "__unix__" instead of "unix".
30248 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
30249 sections were just mistakenly ignored. The former is
30250 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
30251 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
30252 of hpux. This prevents an unwanted definition of the symbol
30253 convert_addresses in adaint.o.
30255 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30257 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
30258 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
30260 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30262 * a-filico.ads, a-filico.adb: fix incorrect header.
30264 2004-10-26 Javier Miranda <miranda@gnat.com>
30266 * a-ststio.ads: Fix typo in identifier
30268 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30270 * sem_ch4.adb: Minor reformatting.
30272 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30274 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
30275 enabled, check the result of unary and binary operations when the
30276 expression is the right-hand side of an assignment.
30278 2004-10-26 Vincent Celier <celier@gnat.com>
30280 * clean.adb (Delete): Do not output warnings when in quiet output and
30281 not in verbose mode.
30282 (Force_Deletions): New Boolean flag, defaulted to False
30283 (Delete): Only delete a file if it is writable, and when
30284 Force_Deletions is True.
30285 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
30286 (Usage): Line for new switch -f
30287 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
30290 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30292 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
30293 JM type only if its size matches that of the wrapper. When a size is
30294 prescribed and the field is not aliased, remove the wrapper of a JM
30295 type only if the size is not greater than that of the packed array.
30296 (gnat_to_gnu_entity): Change the extension of packed array wrappers
30299 2004-10-26 Geert Bosch <bosch@gnat.com>
30301 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
30302 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
30303 (Pred): Implement in terms of Succ.
30305 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30307 * exp_aggr.adb (Safe_Component): An aggregate component that is an
30308 unchecked conversion is safe for in-place use if the expression of the
30309 conversion is safe.
30310 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
30311 be expandable in place even if the aggregate does not come from source.
30312 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
30313 designated object of an allocator in place, rather than building it
30314 first on the stack. The previous scheme forces a full copy of the array,
30315 and may be altogether unsusable if the size of the array is too large
30316 for stack allocation.
30318 2004-10-26 Robert Dewar <dewar@gnat.com>
30320 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
30321 compares if the component is atomic.
30323 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
30324 array assignment if the component type is atomic.
30326 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30327 Eric Botcazou <ebotcazou@act-europe.fr>
30329 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
30330 is aliased and is a by_reference type, do not pass by copy.
30331 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
30332 detect whether the call is in the right side of an assignment or
30333 the expression of an object declaration. Recurse on component
30334 association within aggregates.
30335 Call it in the condition that determines whether the temporary is
30336 necessary for correct stack-checking.
30338 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30340 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
30341 RACW_Type, used in the PolyORB version.
30342 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
30343 version and the GARLIC version.
30345 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
30346 Rename RCI_Info to RCI_Locator for better consistency between the
30347 GARLIC and PolyORB versions of the distributed systems annex.
30348 (DSA_Implementation_Name): This enumeration lists the possible
30349 implementations of the Partition Communication Subsystem for the
30350 Distributed Systems Annex (DSA). The three available implementations
30351 are the dummy stub implementation (No_DSA), and two versions based on
30352 two different distribution runtime libraries: GARLIC and PolyORB. Both
30353 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
30355 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
30358 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
30359 between the GARLIC and PolyORB versions of the distributed systems
30361 Remove RE_Unbounded_Reclaim_Pool since it is unused.
30363 2004-10-26 Gary Dismukes <dismukes@gnat.com>
30365 * gnat1drv.adb: Suppress calling the back end when
30366 Frontend_Layout_On_Target is true.
30368 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30370 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
30371 Set_Read_Only): New subprograms.
30372 These new routines allow the user to set or unset the Owner execute
30373 and Owner write permission flags on a file.
30375 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
30376 GNAT.OS_Lib.Set_Executable instead of rolling our own.
30378 2004-10-26 Matthew Gingell <gingell@gnat.com>
30380 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
30382 2004-10-26 Pascal Obry <obry@gnat.com>
30384 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
30385 memory before the faulting page we properly test the process read
30386 access for this address using appropriate Win32 routine.
30387 (HPUX sections): guard with "__hpux__" instead of "hpux".
30389 2004-10-26 Robert Dewar <dewar@gnat.com>
30391 * lib-xref.adb (Generate_Reference): Don't complain about reference to
30392 entry parameter if pragma Unreferenced set, since we do not properly
30393 handle the case of multiple parameters.
30395 2004-10-26 Vincent Celier <celier@gnat.com>
30397 * prj-env.adb: (Contains_ALI_Files): New Boolean function
30398 (Ada_Objects_Path.Add): For a library project, add to the object path
30399 the library directory only if there is no object directory or if the
30400 library directory contains ALI files.
30401 (Set_Ada_Paths.Add.Recursive_Add): Ditto
30403 2004-10-26 Vincent Celier <celier@gnat.com>
30405 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
30406 extension of library projects.
30408 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
30409 path defaults to ".:<prefix>/lib/gnat".
30410 (Parse): For an extending all project, allow direct import of a project
30411 that is virtually extended.
30413 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
30414 the specified name is directly imported, return its ID. Otherwise, if
30415 an extension of this project is imported, return the ID of the
30418 2004-10-26 Robert Dewar <dewar@gnat.com>
30420 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
30421 (Sub3): New procedure, used by Scaled_Divide
30422 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
30423 correct more than one instance of failure to propagate carries
30425 (Double_Divide): Handle overflow case of largest negative number
30426 divided by minus one.
30428 * s-arit64.ads (Double_Divide): Document that overflow can occur in
30429 the case of a quotient value out of range.
30432 2004-10-26 Robert Dewar <dewar@gnat.com>
30434 * s-bitops.adb (Bit_Eq): Remove redundant check.
30436 * s-bitops.ads: Minor comment updates
30437 Change some occurrences of Address to System.Address
30439 * s-carsi8.ads: Fix minor cut-and-paste error in comments
30441 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30443 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
30444 accessibility check to prefix that is a protected operation.
30446 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30448 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
30449 empty, post message on stub.
30451 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30452 Javier Miranda <miranda@gnat.com>
30454 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
30455 current instance appears within a unit that is directly in the context
30457 Used to determine whether the body of the instance should be analyzed
30458 immediately after its spec, to make its subprogram bodies available
30459 for front-end inlining.
30460 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
30461 constraint is not allowed on the component type (AARM 12.5.3(3))
30463 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30465 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
30466 'Storage_Pool): enhance, document & limit detection of non-sharable
30469 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
30471 * s-pooglo.ads: Add more documentation now that this pool is properly
30474 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30476 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
30477 or protected type with discriminants, do not constrain the
30478 corresponding record type if the subtype declaration has no
30479 discriminant constraints. This can be the case in source code, or in
30480 the subtype declaration created to rename an actual type within an
30483 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30485 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
30486 different kind of stub (possibly wrong name for file), do not check
30488 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
30489 includes call to some function that returns an unconstrained type, do
30492 2004-10-26 Ed Schonberg <schonberg@gnat.com>
30494 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
30495 appear in the code for the main unit. Dependencies among units in the
30496 context of the main unit are established when those other units are
30497 compiled. Otherwise spurious elaboration constraints can generate
30498 incorrect elaboration circularities.
30500 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
30501 Ed Schonberg <schonberg@gnat.com>
30503 * sem_util.adb (Is_Aliased_View): Defend against the case where this
30504 subprogram is called with a parameter that is not an object name. This
30505 situation arises for some cases of illegal code, which is diagnosed
30506 later, and in this case it is wrong to call Is_Aliased, as that might
30507 cause a compiler crash.
30508 (Explain_Limited_Type): Refine previous fix to include
30509 inherited components of derived types, to provide complete information.
30511 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
30512 is the prival for a protected object.
30513 It is necessary to mark this entity as a variable, in addition to
30514 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
30515 modified to avoid checking the Aliased flag on entities that are not
30516 objects. (Checking that flag for non-objects is erroneous and could
30517 lead to a compiler crash).
30519 2004-10-26 Robert Dewar <dewar@gnat.com>
30521 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
30522 X_Frac = 0.5, then we know that the number X must be positive.
30523 (Succ): Remove the same redundant test, and also fix the primary test
30524 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
30526 (Decompose): Add fuller comments to spec
30528 2004-10-26 Pascal Obry <obry@gnat.com>
30530 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
30531 validity (process must have read access). Set to 0 in all other cases.
30532 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
30533 violation on Win32.
30534 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
30535 segmentation violation.
30537 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
30539 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
30540 whose type is a constructed subtype of an aliased object with an
30541 unconstrained nominal subtype, convert the actual to the constructed
30542 subtype before taking its address.
30544 2004-10-26 Vincent Celier <celier@gnat.com>
30546 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
30547 (Is_Path_Name_Case_Sensitive): New function
30549 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
30550 (Base_Name, Simple_Name, Current_Directory, Compose,
30551 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
30554 2004-10-26 Cyrille Comar <comar@act-europe.fr>
30555 Vasiliy Fofanov <fofanov@act-europe.fr>
30556 Vincent Celier <celier@gnat.com>
30558 * gnat_ugn.texi: Generalize "finding memory problems" section into a
30559 "memory management issues" section and document some of the useful
30560 memory pools provided as part of the GNAT library.
30561 Remove "virtual" from declaration of A::method2 in
30562 the simple example of Ada/C++ mixed system.
30563 Library Projects may be virtually extended: their virtual extensions
30564 are not Library Projects.
30565 Added section on extending project hierarchies.
30567 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
30569 * adaint.c (__gnat_get_libraries_from_registry): Cast value
30571 (__gnat_portable_spawn): Remove const.
30573 * mingw32.h (MAXPATHLEN): Check for previous definition.
30575 2004-10-17 Matthias Klose <doko@debian.org>
30577 * gnatvsn.ads: Set gnat library version to 4.0.
30579 2004-10-05 Vincent Celier <celier@gnat.com>
30581 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
30583 2004-10-04 Laurent Guerby <laurent@guerby.net>
30586 * Makefile.in: Define and use RANLIB_FLAGS.
30588 2004-10-04 Pascal Obry <obry@gnat.com>
30590 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
30591 other x86 platforms).
30593 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30595 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
30596 in general and triggers stack alignment adjustment for thread entry
30597 points on targets where this is necessary.
30599 2004-10-04 Bernard Banner <banner@gnat.com>
30602 * Makefile.in: Add section for powerpc linux
30603 Add variant i-vxwork-x86.ads
30605 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
30607 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
30609 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
30610 table registration calls when need be. Ensures no reference to the crt
30611 ctors symbol are issued in the SJLJ case, which avoids possible
30612 undefined symbol errors in the case of modules to be statically linked
30615 2004-10-04 Javier Miranda <miranda@gnat.com>
30617 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
30618 in-line the code corresponding to subprogram Analyze_Actuals. In
30619 addition, analyze the actuals only in case of subprogram call.
30621 2004-10-04 Ed Falis <falis@gnat.com>
30623 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
30625 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
30627 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
30628 in the documentation.
30630 2004-10-04 Robert Dewar <dewar@gnat.com>
30632 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
30634 (Analyze_Block_Statement): Add circuitry to detect following dead code
30635 (Check_Unreachable_Code): Handle case of block exit
30637 2004-10-04 Robert Dewar <dewar@gnat.com>
30639 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
30640 (XMatchD): Avoid warning for Logic_Error call
30642 2004-10-04 Robert Dewar <dewar@gnat.com>
30644 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
30645 consider expressions buried within a procedure actual to be an actual.
30646 This caused some blowups with uses of packed slices within a procedure
30649 2004-10-04 Robert Dewar <dewar@gnat.com>
30651 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
30652 longer need to be initialized to zero.
30653 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
30654 initialized to zero.
30656 * checks.adb (Expr_Known_Valid): Packed arrays are now always
30657 considered valid, even if the representation is modular. That's correct
30658 now that we no longer initialize packed modular arrays to zero.
30660 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
30661 suffixes. These are now documented as the only cases in which the
30662 debugger ignores outer records.
30663 Previously, the spec allowed arbitrary suffixes for this purpose.
30664 Change name of LJM to JM for packed array pad records
30665 Create separate section on packed array handling, and add a whole new
30666 set of comments to this section describing the situation with packed
30667 modular types and justification requirements depending on endianness.
30669 2004-10-04 Robert Dewar <dewar@gnat.com>
30671 * a-except.adb: Add a comment for last change

30680 * sem_util.ads: Minor comment update
30682 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30684 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
30685 Inline_Always when in Configurable_Run_Time mode.
30687 * sem_prag.adb (Process_Convention): If entity is an inherited
30688 subprogram, apply convention to parent subprogram if in same scope.
30689 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
30690 when in Configurable_Run_Time mode.
30692 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30694 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
30695 class_wide type after component list has been inherited.
30697 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30699 * sem_ch12.adb (Check_Generic_Actuals): New predicate
30700 Denotes_Previous_Actual, to handle properly the case of a private
30701 actual that is also the component type of a subsequent array actual.
30702 The visibility status of the first actual is not affected when the
30703 second is installed.
30704 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
30705 make fully recursive the treatment of formals of packages declared
30707 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
30708 the above on exit from an instantiation.
30709 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
30710 current instantiation which is now complete.
30711 (Analyze_Package_Instantiation): No instantiated body is needed if the
30712 main unit is generic. Efficient, and avoid anomalies when a instance
30713 appears in a package accessed through rtsfind.
30715 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30717 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
30718 do not generate a declaration for a temporary if the call is part of a
30719 library-level instantiation.
30721 2004-10-04 Ed Schonberg <schonberg@gnat.com>
30723 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
30724 searching for a limited component to flag.
30726 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
30727 expansion of Input, to account for the fact that the implicit call
30728 generated by the attribute reference must freeze the user-defined
30729 stream subprogram. This is only relevant to 'Input, because it can
30730 appear in an object declaration, prior to the body of the subprogram.
30732 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
30733 expansion can proceed and further errors uncovered.
30734 (Minor clean up): Fix cases of using | instead of \ for continuation
30737 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30745 * decl.c (gnat_to_gnu_entity, case object): Check and process a
30746 specified alignment before validating size.
30747 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
30748 stripped-down declaration for the type of the inner field when making
30751 * utils.c (finish_record_type): Do not compute the size in units
30752 incrementally. Instead compute it once for the rep clause case.
30753 Use gcc_assert and gcc_unreachable.
30755 2004-10-04 Vincent Celier <celier@gnat.com>
30757 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
30759 (Is_Valid_Path_Name): Take '/' as a directory separator.
30761 2004-10-04 Vincent Celier <celier@gnat.com>
30763 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
30764 (Extended_Project) only if Extended_Project is defined, to avoid
30766 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
30768 (Parse_Single_Project): Ditto.
30770 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
30771 Add_To_Project_Path for virtual projects.
30773 2004-10-04 Vincent Celier <celier@gnat.com>
30775 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
30776 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
30777 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
30778 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
30779 parameter Options_2.
30781 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
30782 Build_Dynamic_Library with an empty Options_2.
30784 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
30787 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
30788 directory separator, if any.
30789 (Gprmake): Do not allow mains on the command line for library projects.
30790 Do not attempt to link when the project is a library project.
30791 (Library_Opts): New table to store Library_Options.
30792 (Build_Library): If Library_Options is specified, pass these options
30793 when building a shared library.
30795 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30797 * s-tposen.adb (Service_Entry): The object must be always unlocked at
30798 the end of this procedure now that the unlock operation was inserted
30801 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
30803 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
30804 corresponding to the Preallocated_Stacks flags in System.
30805 (Get_Target_Parameters): Including the processing for
30806 Preallocated_Stacks.

30816 system-solaris-sparc.ads, system-solaris-sparcv9.ads, system-vms.ads,
30817 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
30818 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
30819 used to signal whether the compiler creates the required stacks and
30820 descriptors for the different tasks (when True) or it is done by the
30821 underlying operating system at run time (when False).
30822 It is initially set to False in all targets.
30824 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
30825 if it is supported by the target.
30826 (Make_Task_Create_Call): Pass the stack address if it has been
30827 previously created. Otherwise pass a Null_Address.
30829 * snames.adb: Add _stack.
30831 * snames.ads: Add Name_uStack. Required to allow the expander to
30832 statically allocated task stacks.
30834 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
30835 Stack_Address argument.
30836 Check that its value is equal to Null_Address because this target does
30837 not support the static stack allocation.

30841 * usage.adb: Change "pragma inline" to "pragma Inline" in information
30844 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30846 * exp_dist.adb: Split declaration of asynchronous flag out of
30847 Add_RACW_Read_Attribute.
30848 Minor reformatting for better alignment with PolyORB version.
30849 Store the entity for the asynchronous flag of an RACW, rather than the
30850 expression, in the asynchronous flags table. This will allow this flag
30851 to be used in other subprograms beside Add_RACW_Read_Attribute.
30853 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
30855 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

30859 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
30860 sockets constant MSG_NOSIGNAL (Linux-specific).
30861 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
30862 all Send operations.
30863 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
30864 from trigerring SIGPIPE.
30865 Rename components to avoid clash with Ada 2005 possible reserved
30867 (Check_Selector): When the select system call returns with an error
30868 condition, propagate Socket_Error to the caller.

30878 instead do this at freeze time (we won't do it if there is an address
30880 Change "pragma inline" to "pragma Inline" in information and error
30882 Minor reformatting.
30884 * freeze.adb (Check_Address_Clause): Remove previous change, not the
30885 right way of doing things after all.
30886 (Freeze_Entity): For object, set Is_Public for imported entities
30887 unless there is an address clause present.
30889 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
30891 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
30892 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
30893 ensures proper handling of types with rep clauses, which might have
30894 their TYPE_SIZE set already.
30896 2004-09-21 Robert Dewar <dewar@gnat.com>
30898 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
30899 packed array types in both little- and big-endian cases. This change
30900 ensures that we no longer count on the unused bits being initialized
30901 for such types (and in particular ensures that equality testing will
30902 only read the relevant bits).
30903 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30904 These changes mean that we no longer need to initialize small packed
30906 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
30907 optimization to an LJM field as to its parent field.
30909 * ada-tree.h, trans.c, utils.c, utils2.c:
30910 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
30912 2004-09-20 Jan Hubicka <jh@suse.cz>
30914 * utils.c (gnat_finalize): Remove.
30915 (end_subprog_body): Directly call cgraph_finalize_function;
30916 do not lower the nested functions.
30918 2004-09-20 Robert Dewar <dewar@gnat.com>
30921 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
30922 if an address clause is present, since that means that the Import
30925 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
30927 * 5tsystem.ads: Removed, no longer used.
30929 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>
30930 Zack Weinberg <zack@codesourcery.com>
30932 * ada-tree.def: Use tree_code_class enumeration constants
30933 instead of code letters.
30934 * ada-tree.h, decl.c, misc.c, trans.c, utils.c, utils2.c:
30935 Update for new tree-class enumeration constants.

30951 an existing directory.
30952 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
30953 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
30954 Convert the result to File_Size.
30956 * prj.ads: (Project_Error): New exception
30958 * prj-attr.adb: Except in procedure Initialize, Fail comes from
30959 Prj.Com, not from Osint.
30960 (Attrs, Package_Attributes): Tables moved to private part of spec
30961 (Add_Attribute, Add_Unknown_Package): Moved to new child package
30963 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
30964 Prj.Project_Error after call to Fail.
30965 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
30966 Fail. Check that package name is not already in use.
30968 * prj-attr.ads: Comment updates to indicate that all subprograms may be
30969 used by tools, not only by the project manager, and to indicate that
30970 exception Prj.Prj_Error may be raised in case of problem.
30971 (Add_Unknown_Package, Add_Attribute): Moved to new child package
30973 (Attrs, Package_Attributes): Table instantiations moved from the body to
30974 the private part to be accessible from Prj.Attr.PM body.
30976 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
30977 from new package Prj.Attr.PM.
30978 (Parse_Attribute_Declaration): Call Add_Attribute from new package
30981 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
30983 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
30984 instead of Elaboration_Checks).
30986 * a-calend.adb: Minor reformatting

31028 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
31029 pragmas recognized by GNAT.
31031 * gnat_rm.texi: Document pragma Detect_Blocking.
31033 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
31034 raise Program_Error if called from a protected operation.
31036 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
31037 the protected action nesting level.
31038 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
31039 protected action nesting level.
31040 (Unlock): When pragma Detect_Blocking is active decrease the protected
31041 action nesting level.
31043 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
31044 Protected_Action_Nesting.
31046 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
31047 Common_ATCB record. It contains the dynamic level of protected action
31048 nesting for each task. It is needed for checking whether potentially
31049 blocking operations are called from protected operations.
31050 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
31051 Detect_Blocking is active or not in the partition.
31053 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
31054 raise Program_Error if called from a protected operation.

31063 * s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
31064 raise Program_Error if called from a protected operation, and increase
31065 the protected action nesting level.
31066 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
31067 Program_Error if called from a protected operation, and increase the
31068 protected action nesting level.

31074 the protected action nesting level.
31075 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
31076 Program_Error if called from a protected operation, and increase the
31077 protected action nesting level.

31081 active, raise Program_Error if called from a protected operation.
31082 (Unlock_Entry): When pragma Detect_Blocking is active decrease the
31083 protected action nesting level.
31085 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
31086 insertion of the statement raising Program_Error. The run time
31087 contains the required machinery for handling that.
31089 * sem_util.ads: Change comment associated to procedure
31090 Check_Potentially_Blocking_Operation.
31091 This procedure does not insert a call for raising the exception because
31092 that is currently done by the run time.
31094 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
31096 * init.c: Add the global variable __gl_detect_blocking that indicates
31097 whether pragma Detect_Blocking is active (1) or not (0). Needed for
31098 making the pragma available at run time.
31099 (__gnat_set_globals): Pass and update the detect_blocking parameter.
31101 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
31102 pragma Detect_Blocking is active.
31104 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
31106 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
31107 DB is found in the ali file. Any unit compiled with pragma
31108 Detect_Blocking active forces its effect in the whole partition.
31110 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
31111 Detect_Blocking is active and delay is called from a protected
31114 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
31115 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
31116 Detect_Blocking is active (0 otherwise).
31117 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
31118 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
31121 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
31123 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
31124 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
31127 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
31128 (Register_Receiving_Stub): Add Subp_Info formal parameter.
31129 Update API in placeholder implemetation of s-parint to reflect changes
31130 in distribution runtime library.
31132 * sem_ch3.adb (Expand_Derived_Record): Rename to
31133 Expand_Record_Extension.
31135 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
31136 primitive operations of potentially distributed object types that have
31137 non-controlling anonymous access formals.
31139 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
31141 New implementation of expansion for remote access-to-subprogram types,
31142 based on the RACW infrastructure.
31143 This version of sem_dist is compatible with PolyORB/DSA as well as
31146 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
31147 Asynchrronous that applies to a remote access-to-subprogram type, mark
31148 the underlying RACW type as asynchronous.
31150 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
31151 __gnat_using_gnu_linker to 1.
31153 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
31154 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
31155 GNAT.Perfect_Hash_Generators, and remove the empty

31160 * exp_ch3.adb (Expand_Derived_Record): Rename to
31161 Expand_Record_Extension.
31162 (Build_Record_Init_Proc.Build_Assignment): The default expression in
31163 a component declaration must remain attached at that point in the
31164 tree so New_Copy_Tree copies it if the enclosing record type is derived.
31165 It is therefore necessary to take a copy of the expression when building
31166 the corresponding assignment statement in the init proc.
31167 As a side effect, in the case of a derived record type, we now see the
31168 original expression, without any rewriting that could have occurred
31169 during expansion of the ancestor type's init proc, and we do not need
31170 to go back to Original_Node.
31172 * exp_ch3.ads (Expand_Derived_Record): Rename to
31173 Expand_Record_Extension.
31175 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
31176 Returns the RACW type used to implement a remote access-to-subprogram
31178 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
31179 New subprograms. Used to create a proxy tagged object for a remote
31180 subprogram. The proxy object is used as the designated object
31181 for RAS values on the same partition (unless All_Calls_Remote applies).
31182 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
31183 System.Partition_Interface.Get_Unique_Remote_Pointer.
31184 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
31185 Renamed from Add_RAS_*_Attribute.
31186 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
31188 New implementation of expansion for remote access-to-subprogram types,
31189 based on the RACW infrastructure.
31191 * exp_dist.ads (Copy_Specification): Update comment to note that this
31192 function can copy the specification from either a subprogram
31193 specification or an access-to-subprogram type definition.
31195 2004-09-09 Ed Schonberg <schonberg@gnat.com>
31197 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
31198 in an instance, between an explicit subprogram an one inherited from a
31199 type derived from an actual.
31201 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
31202 add a polling call if the subprogram is to be inlined by the back-end,
31203 to avoid repeated calls with multiple inlinings.
31205 * checks.adb (Apply_Alignment_Check): If the expression in the address
31206 clause is a call whose name is not a static entity (e.g. a dispatching
31207 call), treat as dynamic.
31209 2004-09-09 Robert Dewar <dewar@gnat.com>
31211 * g-trasym.ads: Minor reformatting
31213 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except

31219 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
31222 2004-09-09 Pascal Obry <obry@gnat.com>
31224 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
31225 enable map file generation. Add the right option to generate the map
31226 file if Map_File is set to True.
31228 * gnatdll.adb (Gen_Map_File): New variable.
31229 (Syntax): Add info about new -m (Map_File) option.
31230 (Parse_Command_Line): Add support for -m option.
31231 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

31252 * opt.ads: Add Ada_Version_Runtime constant used to decide which
31253 version of the language is used to compile the run time.
31255 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
31257 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
31258 of variable length temporaries for function return now that the
31259 back-end and gigi support it.
31261 2004-09-01 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
31263 * misc.c (gnat_print_type): Use TYPE_RM_SIZE_NUM.
31265 * trans.c (struct stmt_group): Delete field GLOBAL.

31483 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
31484 discriminants that rename those of the parent, recover names of
31485 original discriminants for the constraint on the full view of the

31516 returning C.int, to avoid using a derived boolean type.
31518 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

31547 ignore overflows on low and high bounds of an index to also account for
31548 differences in signedness between sizetype and gnu_index_subtype.
31549 These are as legitimate as the ones caused by a lower TYPE_PRECISION

35466 complete assignment subtree which is now unnecessary, as the expansion
35467 of inlined call has been improved to preserve a consistent assignment

35469 after checks have been applied, or else unnecessary checks will

35673 (Resolve_Record_Aggregate.Get_Value): Carry out some static check
35675 * sem_ch3.adb (Access_Definition): In Ada 0Y the Can_Never_Be_Null
35676 attribute must be set only if specified by means of the null-excluding
35677 part. In addition, we must also propagate the access-constant attribute

35692 * sem_ch6.adb (Process_Formals): Carry out some static checks.
35693 (Set_Actual_Subtypes): Generate null-excluding subtype if the
35694 null-excluding part was present; it is not required to be done here in
35695 case of anonymous access types.
35696 (Set_Formal_Mode): Ada 0Y allows anonymous access to have the null
35699 * sem_res.adb (Resolve_Actuals): Carry out some static check
35700 (Resolve_Null): Allow null in anonymous access
35702 * sinfo.adb: New subprogram Null_Exclusion_Present
35703 All_Present and Constant_Present available on access_definition nodes
35705 * sinfo.ads: New flag Null_Exclusion_Present on subtype_declaration,
35706 object_declaration, derived_type_definition, component_definition,
35707 discriminant_specification, access_to_object_definition,

35726 * sem_ch12.adb: Add comment for previous change
35728 2004-03-29 Laurent Pautet <pautet@act-europe.fr>
35730 * osint.adb (Executable_Prefix): Set Exec_Name to the current
35731 executable name when not initialized. Otherwise, use its current value.
35733 * osint.ads (Exec_Name): Move Exec_Name from body to spec in order to
35734 initialize it to another executable name than the current one. This
35735 allows to configure paths for an executable name (gnatmake) different
35736 from the current one (gnatdist).
35738 2004-03-29 Ed Schonberg <schonberg@gnat.com>
35740 * exp_ch6.adb (Expand_Call): A call to a function declared in the
35741 current unit cannot be inlined if it appears in the body of a withed
35742 unit, to avoid order of elaboration problems in gigi.
35744 * exp_ch9.adb (Build_Protected_Sub_Specification): Generate debugging
35745 information for protected (wrapper) operation as well, to simplify gdb
35748 * sem_ch6.adb (Analyze_Subprogram_Body): For a private operation in a
35749 protected body, indicate that the entity for the generated spec comes
35750 from source, to ensure that references are properly generated for it.
35751 (Build_Body_To_Inline): Do not inline a function that returns a
35754 * sem_prag.adb (Process_Convention): If subprogram is overloaded, only
35755 apply convention to homonyms that are declared explicitly.
35757 * sem_res.adb (Make_Call_Into_Operator): If the operation is a function
35758 that renames an equality operator and the operands are overloaded,
35759 resolve them with the declared formal types, before rewriting as an
35762 2004-03-29 GNAT Script <nobody@gnat.com>
35764 * Make-lang.in: Makefile automatically updated
35766 2004-03-25 Vasiliy Fofanov <fofanov@act-europe.fr>
35768 * memtrack.adb: Log realloc calls, which are treated as free followed
35771 2004-03-25 Vincent Celier <celier@gnat.com>
35773 * prj-makr.adb (Process_Directories): Detect when a file contains
35774 several units. Do not include such files in the config pragmas or

35783 resolve links when computing the display names.
35785 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
35787 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
35788 attribute reference does not denote a subtype, it can be any
35789 expression that has a classwide type, potentially after an implicit
35790 dereference. In particular, the prefix can be a view conversion for
35791 a classwide type (for which Is_Object_Reference holds), but it can
35792 also be a value conversion for an access-to-classwide type. In the
35793 latter case, there is an implicit dereference, and the original node
35794 for the prefix does not verify Is_Object_Reference.
35796 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
35797 conversion of a discriminant-dependent component of a mutable object
35800 2004-03-25 Ed Schonberg <schonberg@gnat.com>
35802 * freeze.adb (Freeze_Entity): When an inherited subprogram is
35803 inherited, has convention C, and has unconstrained array parameters,
35804 place the corresponding warning on the derived type declaration rather
35805 than the original subprogram.
35807 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
35808 indication on renaming declaration, if formal has a box and actual
35811 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
35812 determine whether to generate an implicit or explicit reference to
35813 the renamed entity.
35815 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
35816 subprogram renaming comes from a defaulted formal subprogram in an
35819 2004-03-25 Gary Dismukes <dismukes@gnat.com>
35821 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
35822 value expressions to ensure that calls within a component definition
35823 will be checked (since those are evaluated during the record type's
35826 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
35828 * s-tpobop.adb: Code clean up:
35829 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

35874 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
35875 declaration for a child subprogram body that acts as a spec, indicate
35876 that the entity in the declaration needs debugging information.
35878 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
35879 full view if the subtype is created for a constrained record component;
35880 gigi has enough information to construct the record, and there is no
35881 place in the tree for the declaration.
35883 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
35884 serial number for the dummy body that is built for analysis, to avoid
35885 inconsistencies in the generation of internal names when compiling
35888 2004-03-22 Thomas Quinot <quinot@act-europe.fr>

35916 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
35917 gnat_ug_wnt.texi: Regenerate.
35919 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
35921 * ada-tree.h: Update copyright notice.
35922 Minor reformatting.
35924 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
35926 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
35927 as regular exception objects and not as mere integers representing the
35928 condition code. The latter approach required some dynamics to mask off
35929 severity bits, which did not fit well into the GCC table based model.
35930 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
35931 exception data objects. We don't it and it would conflict with the other
35932 external symbol we have to generate for such exceptions.
35934 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
35935 the special code for VMS exceptions, since these are now represented
35936 as regular exceptions objects.
35938 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35940 * decl.c (debug_no_type_hash): Remove.

35942 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
35944 2004-03-19 Laurent Guerby <laurent@guerby.net>
35946 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
35947 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
35949 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35951 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
35952 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
35953 (TYPE_RM_SIZE_INT): Directly use type.values.
35954 (TREE_LOOP_ID): Clean up check.
35955 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
35956 TYPE_VALUES, not TYPE_FIELDS.

35966 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
35967 Specific.Set instead of direct call to e.g pthread_setspecific.
35969 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
35971 * adaint.c: Update comments.
35973 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
35974 GNATLIB_SHARED for FreeBSD.
35976 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
35978 * init.c [VxWorks]: Do not fix the stack size for the environment task.
35979 When needed (stack checking) the stack size is retrieved
35980 from the VxWorks kernel.
35982 * Makefile.in: Flag -nostdinc is required when building the run time
35983 for avoiding looking for files in the base compiler.
35984 Add the VxWorks specific version of the package body for
35985 System.Stack_checking.Operations (5zstchop.adb).
35987 * Make-lang.in: Add the object file for
35988 System.Stack_Checking.Operations.
35990 * Makefile.rtl: Add object file for the package
35991 System.Stack_Checking.Operations.
35993 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
35995 * s-stache.ads, s-stache.adb: Move the operations related to stack
35996 checking from this package to package System.Stack_Checking.Operations.
35997 This way, stack checking operations are only linked in the final
35998 executable when using the -fstack-check flag.
36000 2004-03-18 Doug Rupp <rupp@gnat.com>
36002 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
36005 * 5qsystem.ads, 5xcrtl.ads: New files.

36011 * prj-env.adb (Source_Paths, Object_Paths): New tables.
36012 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
36013 the procedures Add_To_Path_File.
36014 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
36015 making sure that each directory is present only once and, for object
36016 dirs, when a directory already present is added, the duplicate is
36017 removed and the directory is always put as the last in the table.
36018 Write the path files at the end of these accumulations.
36020 * prj-nmsc.adb (Record_Source): Add source file name in hash table
36021 Files_Htable for all sources.
36023 * prj-proc.adb (Process): Remove restrictions between not directly
36024 related extending projects.

36034 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
36036 * scn.adb (Determine_License): Take into account a degenerated case
36037 when the source contains only comments.
36039 2004-03-18 Ed Schonberg <schonberg@gnat.com>
36041 * sem_warn.adb (Check_References): For a warning on a selected
36042 component that does not come from source, locate an uninitialized
36043 component of the record type to produce a more precise error message.
36045 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
36047 * 3zsoccon.ads: Fix multicast options.
36049 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
36052 2004-03-15 Robert Dewar <dewar@gnat.com>
36054 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
36055 pragma used for a private type.
36057 * lib-xref.adb (Generate_Reference): Do not generate warning if
36058 reference is in a different unit from the pragma Unreferenced.
36060 * 5vtpopde.adb: Minor reformatting
36061 Fix casing of To_Task_ID
36063 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
36064 flag if we have an unchecked conversion to an access type in the same
36067 2004-03-15 Geert Bosch <bosch@gnat.com>
36069 * a-ngcoty.adb (Modulus): In alternate formula for large real or
36070 imaginary parts, use Double precision throughout.
36072 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
36073 we want to be able to compile run-time with -gnata for testing, but
36074 this may also be instantiated in user code that is compiled with -gnata.
36076 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
36078 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
36079 codes. Having a separate type for this is useful to enforce consistency
36080 throughout the various run-time units.
36081 (Exception_Data): Use Exception_Code for Import_Code.
36083 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
36084 Natural and Integer in various places.

36086 with the severity bits masked off.
36087 (Register_VMS_Exception): Handle the additional exception data pointer

36091 component, now reflected by an exported accessor.
36092 (is_handled_by): New routine to compute whether the propagated
36093 occurrence matches some handler choice specification. Extracted out of
36094 get_action_description_for, and expanded to take care of the VMS
36096 (get_action_description_for): Use is_handled_by instead of an explicit
36097 complex condition to decide if the current choice at hand catches the
36098 propagated occurrence.
36100 * raise.h (Exception_Code): New type for C.
36102 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
36103 System.Standard_Library.Exception_Code, to allow references from the
36104 pragma import/export expander.
36106 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
36107 New accessors to allow easy access to GNAT exception data
36109 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
36110 redundant Handled_By_Others component, helper for the personality
36111 routine which will now be able to call the appropriate exception data
36114 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
36115 component of Standard_Exception_Type to be the closest possible to
36116 Exception_Code in System.Standard_Library, that we cannot get at this
36117 point. Expand a ??? comment to notify that this type node should
36118 probably be rewritten later on.
36120 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
36121 registration call to include a pointer to the exception object in the
36124 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
36125 instead of int and explicit bitmasks.
36127 2004-03-15 Vincent Celier <celier@gnat.com>
36129 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
36130 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
36132 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
36133 longer needed now that it is in the spec of
36134 System.Tasking.Task_Attributes.
36136 * adaint.h, adaint.c: (__gnat_create_output_file): New function
36138 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
36140 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
36142 * make.adb (Gnatmake): Do not check the executable suffix; it is being
36143 taken care of in Scan_Make_Arg.
36144 (Scan_Make_Arg): Add the executable suffix only if the argument
36145 following -o, in canonical case, does not end with the executable
36146 suffix. When in verbose mode and executable file name does not end
36147 with executable suffix, output the executable name, in canonical case.
36149 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
36150 to avoid warnings when instantiating Ada.Task_Attributes.
36153 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
36154 in the correct order.
36156 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
36157 redirect standard output and error to a file for the invocation of the
36158 compiler, then read the file.
36160 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
36161 directory, instead of the Value.
36162 (Find_Source_Dirs): Remove useless code & comments.
36164 2004-03-15 Ed Schonberg <schonberg@gnat.com>
36166 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
36167 tagged type is inherited, and the parent operation is not frozen yet,
36168 force generation of a freeze node for the inherited operation, so the
36169 corresponding dispatch entry is properly initialized.
36170 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
36171 when looking for user-defined equality operation.
36173 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
36174 boolean when locating primitive equality of tagged component.
36176 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
36177 bit-aligned field and the right-hand side a string literal, introduce

37120 checks for bitfield creation are triggered.
37121 (finish_record_type): During last pass over the fields, clear
37122 DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is

37581 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
37582 N_String_Literal node always references an E_String_Literal_Subtype
37583 entity. This may not be true in the future.
37584 (Possible_Bit_Aligned_Component): Move processing of
37585 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
37587 * exp_ch6.adb (Expand_Thread_Body): Pick up

37592 (Type_May_Have_Bit_Aligned_Components): New function.

37632 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
37633 ineffective elaborate all pragmas on non-visible packages (this
37634 happened when a renamed subprogram was called). Now the elaborate all
37635 always goes on the package containing the renaming rather than the one
37636 containing the renamed subprogram.
37638 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
37639 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

37664 * make.adb (Gnatmake): Special process for files to compile/check when
37665 -B is specified. Fail when there are only foreign mains in attribute

37700 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
37701 all attributes, including read-only attribute.

37740 checked when limited aggregates are implemented.

37743 pure, emit warning.

37856 to __gnat_map_signal, imported from init.c to support
37857 signal -> exception mappings that depend on the vxWorks version.
37860 Created and exported __gnat_map_signal to support signal -> exception
37861 mapping that is dependent on the VxWorks version.

37894 * exp_ch7.adb (Establish_Transient_Scope): If the call is within the
37895 bounds of a loop, create a separate block in order to generate proper
37896 cleanup actions to prevent memory leaks.
37898 * sem_res.adb (Resolve_Call): After a call to
37899 Establish_Transient_Scope, the call may be rewritten and relocated, in

37918 2003-12-08 Robert Dewar <dewar@gnat.com>
37920 * 7sintman.adb: Minor reformatting
37922 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
37923 standard linker options to get standard libraries linked. We now plan
37924 to provide dummy versions of these libraries to match the appropriate
37925 configurable run-time (e.g. if a library is not needed at all, provide
37926 a dummy empty library).
37928 * targparm.ads: Configurable_Run_Time mode no longer affects linker
37929 options (-L parameters and standard libraries). What we plan to do is
37930 to provide dummy libraries where the libraries are not required.
37932 * gnatbind.adb: Minor comment improvement

37948 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
37949 to indicate that the initialization call corresponds to a
37950 default-initialized component of an aggregate.
37951 In case of default initialized aggregate with tasks this parameter is
37952 used to generate a null string (this is just a workaround that must be
37953 improved later). In case of discriminants, this parameter is used to
37954 generate a selected component node that gives access to the discriminant
37957 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
37958 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
37959 allocated aggregates with default-initialized components.

38004 Process nodes N_Comment.
38006 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
38007 without comments and there are some comments, set the flag
38008 Unkept_Comments to True.

38050 Correct typo in comment
38051 (Resolve_Aggregate): In case of array aggregates set the estimated
38052 type of the aggregate before calling resolve. This is needed to know

38077 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
38078 they are automatically generated by Make-lang.in and cause nothing but
38079 maintenance troubles.

38097 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
38098 to ensure that the kernel fills in the interrupted context structure
38099 before calling a signal handler, which is necessary to be able to
38100 unwind past it. Update the copyright notice.
38102 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
38104 * a-elchha.ads: New file.

38191 2003-12-03 Ed Schonberg <schonberg@gnat.com>
38194 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
38195 is legal in an instance, because legality is cheched in the template.

38216 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
38217 so that the debugger can reliably access the value of the parameter,

41124 2002-09-23 Zack Weinberg <zack@codesourcery.com>
41126 * Make-lang.in (EXTRA_GNATBIND_OBJS): Add version.o.
41127 * Makefile.in (TOOLS_LIBS): Add ../../version.o.
41128 * gnatvsn.ads: Gnat_Version_String is now a function.
41129 * gnatvsn.adb: New file. When asked for Gnat_Version_String,
41130 copy the C version_string into a String and return it.
41131 * gnatcmd.adb, gnatkr.adb, gnatlbr.adb, gnatlink.adb,
41132 gnatls.adb,gnatmake.adb, gnatprep.adb, gnatpsta.adb:
41133 Remove pragma Ident (Gnat_Version_String). If this was the
41134 sole use of package Gnatvsn, remove the with statement too.

41724 from mdllfile.ad[bs] and mdlltool.ad[bs]
41726 2002-03-03 Kaveh R. Ghazi <ghazi@caip.rutgers.edu>
41728 * utils.c (init_gnat_to_gnu, init_gigi_decls): Use ARRAY_SIZE in

41746 2002-01-30 Richard Henderson <rth@redhat.com>
41748 * trans.c (tree_transform) [N_Loop_Statement]: Use
41749 expand_exit_loop_top_cond.

41766 (title page): Remove date.
41767 (general) Add @./@: where approriate, and two spaces after the
41768 full stop at the end of a sentence. Use @samp markup when
41769 referring concrete lexical entities (keywords, attribute names
41770 etc.), and @syntax for ARM grammar elements. Use @r for English

41786 function approach did not work well because of a side effect (the
41787 function call could reallocate the table which was being indexed
41788 using its result). Fixes ada/4851.

41826 * raise.c (__gnat_eh_personality): Exception handling personality
41827 routine for Ada. Still in rough state, inspired from the C++ version

41849 * g-regpat.adb: Change pragma Inline_Always to Inline. There is no
41850 need to force universal inlining for these cases.
41852 2001-12-19 Arnaud Charlet <charlet@gnat.com>
41854 * s-taprob.adb: Minor clean ups so that this unit can be used in

41883 * trans.c (tree_transform, case of arithmetic operators): If result
41884 type is private, the gnu_type is the base type of the full view,
41885 given that the full view itself may be a subtype.

42155 2001-12-17 Laurent Pautet <pautet@gnat.com>
42158 Fix comment of Shutdown_Socket and Close_Socket. These functions
42159 should not fail silently because if they are called twice, this
42160 probably means that there is a race condition in the user program.
42161 Anyway, this behaviour is consistent with the rest of this unit.
42162 When an error occurs, an exception is raised with the error message
42163 as exception message.

42316 reference nodes, since this field is used in such nodes.

43498 (Time_Stamp_Mismatch): use CRC_Match for comparison.
43499 (Set_Source_Table): idem.
43502 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
43503 instead of simple checksum.
43504 (CRC_Match): new function.
43505 (CRC_Error): new constant.
43507 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
43508 a CRC now and not a simple checksum. A CRC uses lower-case hex
43509 letters, fixes ambiguity in parsing.
43511 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
43512 is what this variable will store.
43514 * bcheck.adb: Change reference to chechsum in comments by CRC.
43515 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
43516 rename All_Checksum_Match to All_CRC_Match. Change due to API
43517 renaming since now GNAT does not use a simple checksum but a
43518 CRC using GNAT.CRC32.
43520 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
43521 now and not anymore a simple checksum.

43558 Update comments for the CRC.
43560 * types.adb (Hex): Use lowercase for the letter part.
43562 * types.ads (Get_Hex_String): Returns the hexadecimal representation
43563 for a word. This is currently used only for CRC. In previous version,
43564 the checksum was using a representation with all letter being
43565 upper-case. With the new implementation (using CRC) we do not remove
43566 the 32th bit of the CRC, so we can have an upper-case starting letter
43567 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
43568 It is ambigous since the CRC was optional and could be followed by
43569 options like EB, EE. So now this routines uses lower-case letter for
43570 the hexadecimal representation. Strange enough only lower case letters
43571 where checked in Scan_ALI (even if this was not a possible case).
43573 * gnatvsn.ads (Library_Version): changed to 3.15a.
43575 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
43578 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
43581 * ali-util.adb: Redo previous change to avoid using word CRC everywhere
43582 Add 2001 to copyright notice
43583 (Accumulate_Checksum): Modify to use System.CRC32.
43585 * ali-util.ads: Redo changes of previous revision to continue to use
43586 the word Checksum. Add 2001 to copyright notice.
43588 * ali.adb: Undo some of previous changes, not needed.
43589 Keep the change for lower case letters in the checksum.
43591 * ali.ads: Undo previous change not needed.
43593 * bcheck.adb: Undo most of previous change, not needed.
43594 But do use Checksums_Match for checksum comparison.

43597 But do use Checksums_Match for comparing checksums.
43599 * lib-load.adb: Undo previous change, not needed.
43601 * lib-writ.adb: Undo previous change, not needed.
43603 * lib-writ.ads: Document that checksums use lower case,

43621 * sinput.adb: Undo previous change, not needed.
43623 * sinput-l.adb: Undo previous change, not needed.
43625 * sinput.ads: Undo previous change, not needed. Keep only comment
43626 on new checksum algorithm
